INTRODUCTION
O
ver twenty years have passed since the editors at McGraw-Hill
received the manuscript for the first edition of this book. Back
then, they measured it up and declared it was more than they had
bargained for—both in words and illustrations. So everyone looked at
it, hoping to find chapters, or parts of chapters, that could be cut. After
a while, it became evident that the book would be more helpful to its
readers as it stood. So nothing was cut and the publisher kindly agreed
to put out a longer and more profusely illustrated version than
originally planned.
In a sense, the same thing happened with the second edition,
which came out in 1991. Except for a few minor changes, little of the
original material was deleted, because almost everything still held
true. At that time, additional information was included in many chapters. The book became thicker, packed with new material.
The third edition, published in 1999, received a general overhaul,
with numerous chapter upgrades and many new sections. Manufacturers continued to get better at what they do—designing and making
innovative home products. Outdated information was stricken from
the previous edition, replaced by discussions about better components
and construction techniques that gave homebuilders more options
than ever before.
That leads us to this, the fourth edition. Like the others, this edition
also contains more information than the publisher expected. But we
couldn’t help it. Current conditions demanded a concentrated focus
on energy conservation. Why? Have you fueled up your car, van or
truck lately? If so, remember when paying $1.50 per gallon unleaded
seemed like robbery? Today that would be a bargain. The sad truth is
that fuel costs—including home heating and cooling prices—are likely
to keep rising. They may back down a bit, for a while, but competition

INTRODUCTION
for raw materials and energy is heating up as countries such as China,
India, and others industrialize to supply modern living conditions and
goods to their citizens. To help ease the pain of rising energy prices,
the fourth edition of this book features practical information on construction details that will save homeowners energy and money. Lots of
energy and money. Realistic, cost-effective ways of including energysaving components in your new home are discussed in practically
every chapter of this edition.
But saving energy and money are not the only reasons to take charge
of your homebuilding process. We live—now, more so than ever—in an
age of information. We know more about practically everything.
Motion pictures and television, supported by the print media, bring
video and audio segments of war, ethnic atrocities, natural disasters,
and political unrest into our very living rooms. Cable and satellite television carry 24-hour programming on nearly every imaginable subject.
You want round the clock coverage of the financial markets worldwide? How about an unending succession of cooking shows? You’d
like health, medicine, and wellness? Or fishing, golf, professional
wrestling, country western music, rock videos? Do you like romance
movies? Science fiction? Home shopping networks? Travel channels?
Court TV? News headlines? History? Cartoons? Science? Weather? You
name it. There are channels that focus on nothing but home and garden. Watch a side-to-side split-level from planning stage to move-in
condition. The Internet, which has literally come of age since the first
edition of this book, can quickly tap what seems to be an endless supply of details about any topic. Personal computers, ever more powerful
and accessible, run CD-ROMs containing enormous amounts of information, which will help you select from various products to consider
for your home. The Internet will also supply information on products
available from numerous manufacturers. In short, there’s an incredible
amount of information out there, which can be had for the asking.
To acquire such a cosmopolitan array of information, we’ve had to
trade off much of the basic knowledge that our fathers and their fathers
and grandfathers had once known. Granted, they had learned such
knowledge not by choice, but by necessity. A few hundred years ago,
for example, people grew their own food, doctored their own sick, and
built their own homes—with their own hands. They took care of all
their basic needs by themselves.
INTRODUCTION
Thanks to the collective progress realized over the past few centuries, much of that all-around knowledge has become of little use to
the average person. How many people must still be able to shoe a
plowhorse, dig their own well, deliver their own babies, or even teach
their own children how to read and write?
Today, if you’re an accountant, you’re an accountant. You have to
keep up with an avalanche of changing accounting information to service your clients. If you’re a farmer, you’re a farmer, and you have to
subscribe to the latest agricultural techniques to be a success. Or, if
you’re a builder of houses, you’re a builder of houses.
If you can’t perform in whatever business you’re in, and if you
don’t really know the ins and outs of the trade, you’ll be supplanted by
other professionals who do. Specialists who keep up-to-date with the
evolving nature of their business will acquire the competitive edge
needed to stay ahead of their peers. Consequently, people no longer
have the time, need, or inclination to acquire many of the basic skills
our forefathers found unavoidable.
Take the subject of houses, for example. Because the public has
largely turned the job of housebuilding over to a group of professional
builders, not many people really understand exactly what a house
consists of, or how all the parts must mesh together to make a satisfactory dwelling.
And that’s the reason for this book. The idea is simple enough: by
understanding houses, you can better arrive at an understanding
house—one that suits you perfectly, one that is constructed to give
maximum enjoyment and value with minimum investment.
Everybody has to live somewhere, that’s a fact. You can live at
someone else’s place for free, with parents or benevolent friends. Or
you can make do at a place provided by an accommodating employer.
You can reside at someone else’s place and pay rent. Then again, you
can choose to live in something you own. And at some point in their
lives, most people prefer the latter option. This book has been written
for people in search of a modern home situated in either a subdivision
down the street or on five acres out in the boondocks. Although it
focuses on new construction, it also proposes what to look for in existing houses, new or old.
Without knowing better, people considering the purchase of a new
house will approach one or more builders with a sketch and floor plan
xvii

INTRODUCTION
ripped out of a magazine. Then they’ll ask the builder how much he’ll
charge to complete that same house for them. Depending on the
amounts and quality of materials used, or rather, depending on what
specifications or “specs” are followed, the cost of a 2000-square-foot
two-story house can vary by tens of thousands of dollars. By providing
only a simple generic floor plan as a building guide, eager buyers overlook important pre-construction choices that should, in fact, be made
by the buyers themselves. Instead of exercising their own wishes in
the planning and construction of their new house, these trusting buyers leave consequential decisions completely up to the builder.
Another irony is that, when faced with such a complex and expensive task as the purchase of a new house, most people remain interested merely in the basic floor plan, the amount of square footage of
living space, the appearance of the exterior sheathing, and other incidentals such as the color of the flooring and carpeting and the style
and stain of kitchen cabinets. Rarely do they care what thickness the
outer walls will be, or on which side of the house the garage should be
located. They leave detail after detail to the builder’s discretion.
Naturally, in this competitive business, the builder provides what
the buyer wants in a manner most advantageous to the builder himself.
He tends to use materials that he’s been using on other houses he’s
built, and he probably gets them in bulk, at a discount. Unless otherwise requested, this usually means he’ll provide the absolute minimum specs needed to satisfy local building codes, even when, for a
few dollars more, substantial long-range savings and additional conveniences can be enjoyed by the buyers.
Most minimum building codes can be satisfied with economygrade materials. “Economy grade” is a misleading term at best, because
materials in that class actually end up costing more than materials of
high quality, due to frequent maintenance and repairs needed and
shorter life spans. That can mean early replacements, all at extra cost
and inconvenience to the homeowner. And marginal products,
because they’re less durable, can lead to a very annoying and even
uncomfortable house. Unfortunately, marginal quality materials are
found not only in low-priced houses, but in many high-priced
dwellings as well.
High-quality flooring, paneling, wiring, heating, and many other
products cost only a little more, by and large, than the same products
INTRODUCTION
of marginal quality. Certainly, the installation costs are about the same
in either case; an identical amount of labor is required to put down a
new floor of the best or worst vinyl. All things considered, studies
indicate that the initial price of a house built with high-quality materials will run only about 8 to 10 percent more than an identical economygrade dwelling.
The argument to go with quality materials is a persuasive one. But
even before that comes the question: do you want to build a new house
or move into an existing one?
It’s entirely possible to find an older or recently built house that
meets most of your needs, and is constructed similar to the guidelines
described in the following chapters. Such houses can be difficult to
locate, but in many cases, due to circumstances of the present owners,
you can get more house for the money, but not without certain tradeoffs: the house might be in a location you don’t like, or it might have
everything you asked for except a basement, a den, or a two-car garage.
With new construction you have the opportunity to custom design
your own house. With new construction you’ll end up with more
built-in conveniences, with better insulation and more energy efficient
appliances and heating/cooling systems. There are also less repairs to
worry about and less time spent maintaining things, especially with
many of today’s maintenance-free items. New homes generally require
lower down payments, with better financing terms available to owners. Kitchens can be loaded with modern appliances and built-ins.
There are better roofing materials, flooring, easy-care carpeting, windows, and exterior sheathings. And it’s also a nice feeling to move into
a house knowing that you and your family will be the first to live there.
It has that wonderful sweet new-house smell of sawdust, plaster, and
carpeting.
New homes are clean to the eye and touch, and hold their value
well when soundly constructed. Everything is under warranty. You
know exactly what went into the place, having periodically inspected
its erection. You know that it’s a structurally sound dwelling, built
with the latest high-quality, energy-efficient materials.
No matter what you decide to go with—new construction or an
existing home—buying any house is a major investment. Let’s face it,
finding or arriving at the right house for you can be a tough (though
enjoyable) process. It’s not like buying a stereo, for example, where
xix
xx
INTRODUCTION
you can walk into a stereo store and listen to different brands and different models, turn them on, one after another. You can pick up a Consumer Reports and read reviews on them. You can shop for the same
models all over town.
But a house? The two biggest words in real estate have always been
“buyer beware,” and for no small reason. There are endless possibilities open to house buyers and endless pitfalls.
A house is a lot more than a “hedge against inflation” or a pleasant
alternative to paying rent. And sure, owning property will probably
give you the urge to become involved with the community, and will
probably encourage you to send out roots. But most of all, a house is a
dwelling in which human drama unfolds. Children grow up in houses.
Marriages and other relationships flourish or flounder in them, in
unique environments created within the home’s outer shell. In homes
we grow up, learn things, spend time together, eat, play, party, laugh,
fight, cry, make love, pray, and entertain one another. Homes reflect
our personalities and uniqueness, and they deserve to be acquired as
the result of careful deliberation instead of happenstance.
Everybody has to live somewhere. If you have a say in the matter,
then exercise it. Get involved with selecting what you’re going to live
in. It only makes sense. Why settle for less? Why put up with a building that doesn’t meet your and your family’s basic requirements?
Especially if within those same means you have the ability to attain
a dwelling far superior, with an optimal plan custom tailored to your
needs.
Talking new construction, you have to familiarize yourself with
building jargon (it’s not tough) and prepare yourself for entering into a
close and beneficial relationship with a general contractor who builds
houses for a living. You must understand the advantages and disadvantages of the various types of homes available in order to make an
educated choice: ranch, Cape Cod, two-story, split foyer, or split-level.
You should know how to arrange the rooms you choose for the
greatest convenience of both initial construction and everyday living.
Beyond that, you should figure out if you might want to enlarge the
house at a later date. If so, a few relatively minor modifications up
front can mean a lot of savings later. You need to know how to match
the home you want to a building site. And you need to know additional do’s and don’ts along the way. In fact, in many cases, just know-
INTRODUCTION
ing what not to do will lead you to a correct choice. It’s a complex mix
of qualities and factors that can make a difference between ending up
with an extremely pleasant and valuable home, or a disaster.
But don’t worry. Again, it’s not that hard to acquire a lot more
house than you ever thought you could afford—one built with conveniences and quality not usually included with your neighbor’s house.
And it will be a lot of fun.
To get the most out of this book, first read the table of contents for a
general idea of what’s covered. Then take it a chapter at a time, section
by section, at a leisurely pace. Make notes on the numerous ideas that
will result in energy savings.
After you’ve read the entire book, you can proceed with confidence
that you are sufficiently prepared. Arrive at the house you want—in
your mind and on paper. Use the checklists and summary points
throughout the book so you don’t ignore any important considerations.
Determine what construction costs are running by going to open
houses and by asking builders and real estate agents at those open
houses. Realtors can provide valuable and free financial information,
perhaps a helpful summary of mortgage rates in your area. And they
can be instrumental in putting together packages requiring creative
financing (especially when a sale hinges upon you getting the loan).
Although no one person could possibly use every shred of information contained in this book, together the details provide a comprehensive backdrop from which readers can draw whatever is needed to
help illuminate their own specific situations.
Okay. Enough talk. Now let’s get into it. Let’s begin with some style.

What to Build
T
o arrive at the best-possible home for yourself, first take a step
back—away from houses and house construction in general—and
review some basic concepts about what a home can and should contain. You need to think about the pros and cons of the various house
styles and types available, and how you can arrive at floor plans that
will most favorably suit your present and future needs. You should
realize that features can be built into a new house, at minor cost, that
will permit efficient and convenient expansion of living space years
later. And you should also be mildly familiar with typical house construction plans, prints, and drawings.
It’s best to arrive at your “ideal” house on your own, with the help of
books or articles, before approaching builders who will naturally, even
with good intentions, lead you toward house types they prefer or think
that you should prefer. But if you already have a building site picked
out, and your brother-in-law happens to be a builder, so be it. Still, read
the chapters about what to build. If your initial plans (or those of your
brother-in-law) are correct, then you’ll be able to proceed full of confidence. On the other hand, if you discover that a different type of house
would be better for you, don’t let anyone tell you otherwise.
Don’t be one of the thousands of home buyers who are just on the
receiving end of a new house, passively accepting whatever happens
along. Let there be conscious reasons for everything you end up with.

CHAPTER
1
A House Divided
The modern house consists of at least six main types of areas:
■ Living and Recreation Space. In any one dwelling, this can
include a living room, family room, den, library, music room, sunroom, or other rooms and niches planned for entertainment, relaxation, hobbies, or study.
■ Food Preparation Space. The kitchen ranks number one here, fol-
lowed by additional food storage areas such as nearby walk-in
pantries and “satellite” serving platforms, bars, and grills conveniently located in family rooms and other living and recreational
spaces.
■ Dining Space. Depending on the floor plan, this can be a separate
formal dining room adjacent to the kitchen, or an open dining area
having the kitchen on one side and the living room or family room
on another. Or, when economy is desired, a portion of the actual
kitchen itself can be reserved for a dining table or booth.
■ Bathing and Washing Space. This means bathrooms, both full and
half, plus toilets, hand sinks, showers, saunas, and indoor hot tubs.
■ Sleeping and Dressing Space. Bedrooms, dressing nooks, and
related storage areas.
■ Service and Storage Space. Everything else in a house fits in here:
basement, attic, stairs, hallways, laundry rooms, and garages.

WHAT TO BUILD
LIVING AND RECREATION SPACE
We’ve come a long way since our primitive ancestors stalked
through forests in search of daily sustenance. Indeed, prehistoric life
was tough. There were no plumbers, no cable televisions, no supermarkets, doctors, or economists. Instead you had one continuous struggle against the elements, with little time to do anything but attempt to
satisfy the most basic of needs. And even if the typical primitive had
the time, he or she still wouldn’t have known how to put a formal living room to good use.
Okay, so they did have dens—in the strictest sense of the word (Fig.
1.1). Back then a shelter was just that—a few walls against which to huddle. There was a roof for protection from rain, sleet, and snow, under
which early humans could hunker down, relatively safe from predators.
Even though our primitive forerunners had the protection of rough
shelters, they were still lucky just to make it through their teens in one
piece. In fact, as late as the early 1900s, the expected American life
span was only 46 years for men and 49 for women. That didn’t leave
much free time for recreation.
F I G U R E 1 .1
A primitive den.
A HOUSE DIVIDED
Thanks to revolutionary medical and pharmaceutical advances,
look how long people are living today. Consider also, especially during the latter half of this century, how work weeks have grown shorter
and family sizes smaller. Automobiles, trucks, and aircraft have given
us mobility, and sped up the delivery of time-saving conveniences to
our doors. New leisure time has created a demand that greater attention be paid to the living and recreational space in modern dwellings.
Simply put, a house’s living and recreation rooms should contain
enough space to satisfy the needs of its occupants. It means enough
space for general and specific leisure activities such as entertaining
friends, watching television, listening to music, practicing musical
instruments, gaming, reading, studying, writing, bookkeeping, children’s play, and plain old relaxing . . . all in comfort, and, if need be,
privacy.
Living and recreation rooms must also be adequate in size to hold
sufficient furniture for comfortable seating. At the same time they
should be large enough to permit the rearrangement of major pieces of
furniture into a variety of positions while still maintaining good traffic
circulation within the room.
Depending on a dwelling’s size and floor plan, living and recreational space may be planned as a number of individual rooms, or may
be distilled into a single, all-purpose area.
The Living Room
If one all-purpose room is all you desire, or all you can afford at the
outset, that room should probably be the living room. At one time
referred to as a parlor, the living room was originally designed to entertain guests in a formal fashion. The living room should be at a quiet
place for reading and conversation. It should be close to the front door,
next to dining space, and away from sleeping areas. There should also
be a closet outside the living room, near the front door, for coats, hats,
boots and other items. There are two main types of living rooms: traditional and open.
A traditional living room is a room placed away from the kitchen and
other work or recreational rooms in the house. This out-of-the-way
placement allows at least two separate entertainment centers (including
the kitchen in a smaller house) so that more than one family member
can plan activities with outside friends at the same time, without
5
6
WHAT TO BUILD
infringing on each other’s privacy. The traditional living room is usually
situated at a dead-end location to minimize unwanted interruptions and
through traffic. Doors can be considered for additional privacy.
As mentioned earlier, if the house you plan will not accommodate
other recreation rooms beyond a living room, then consider that your
living room will have to be used for whatever leisure-time activities
you enjoy. When a single room must serve a variety of functions, a
more open type of room is often the most practical choice. In fact, due
to the overall reduction of square footage in recent years for cost reasons, open planning is becoming increasingly important because it
lends the impression of maximum space for the money. In fact, it does
give you more square footage of usable space, because there are less
walls to take up space. Open planning serves well in the more contemporary and expensive plans, and in households having few or no
children, where privacy is not as important as it would be to a large
family. However, a danger in open-type rooms is that spaces must be
carefully planned so they don’t appear jumbled and haphazardly
thrown together.
The Family Room
A second recreational room that has grown popular in the past few
decades is the family room. Instead of wearing out the living room furnishings, informal activities such as children’s play, listening to
music, and lounging on sofas while watching television can be comfortably pursued in a more casual environment.
A home that contains both a living room and a family room will
typically have the main television set placed in the family room. And
like it or not, television has become a mainstay in most modern households. On average, the tube is on for over seven hours per day, 365
days per year in every household that has one. Videocassette players
are practically as common as toasters.
Because people want the television where groups of family members and guests can watch it comfortably, it has a definite impact on
interior decoration. This means a wall or corner is effectively removed
from the placement of seating and other furniture. Thus, when the
room is originally sized and laid out, the television placement should
be taken into account: preferably some spot where the glaring sun will
not interfere with viewing.
A HOUSE DIVIDED
If you plan to have a separate family room in addition to a living
room, consider locating it next to the kitchen, where only a few steps
will separate food and drink from leisure-time activities, and where a
parent can still work in the kitchen while supervising children at play.
Another desirable feature for a family room is an outdoors access,
commonly provided by sliding glass doors that lead to a patio, terrace,
or deck. Although some people add doors to the family room to
seclude it from the rest of the house, most active families prefer an
open-type plan allowing easy movement to and from the kitchen and
fostering efficient communications between the two areas.
Fireplaces
Whether you decide upon one living room/family room combination, or multiple living and recreation rooms, one feature to consider—even in the warmer climates—is a fireplace.
When planned from the beginning, one or more fireplaces can be
integrated in the house in such a manner as to save space, materials,
and money. For instance, if the back of a fireplace is located inside the
garage, you can reduce the number of expensive finishing bricks or
stones normally needed to construct an outside wall chimney. Not
only that, but instead of dissipating heat outside through an outer
chimney wall, some heat will radiate into the garage, where it will do
some good. The ash cleanout door can be built so it opens at a convenient height within the garage, where messy ashes and grits can be
removed and disposed of in one efficient step. No more trudging
across carpets, or climbing stairs.
If you plan to put a fireplace in a first-floor living or family room,
consider two other points: First, if your house will have a basement,
do you plan on doing much socializing there? If so, you might want to
include a second fireplace. Then an economical way would be to align
both fireplaces one right over another.
Second, due to their very nature, fireplaces demand comfortable
seating around them, and require freedom from internal traffic and
other interference. Therefore a door next to a fireplace is poor design.
Anyone entering or exiting the room through such an access becomes
an immediate intruder, an interruption to the conversation group. A
door near a fireplace also prevents the placement of furniture on that
side of the hearth, creating wasted space that in turn will effectively
7
8
WHAT TO BUILD
shrink the amount of usable space in a large living or family room
down to that of a much smaller area.
Windows and Glass Doors
An important feature common to all living and recreation rooms
are windows and glass sliding doors. While you should make sure that
living and recreation rooms are bright and cheerful from natural light,
and plenty of ventilation is provided, too much glass—especially sliding glass doors and floor-to-ceiling windows—can pose a number of
irritating problems:
1. If too much wall space consists of glass there might be no place to
arrange furniture unless you decide to block off some of the glass
with a piece of furniture such as a sofa or plush chair.
2. If you deliberately decide to place furniture in front of glass, consider how the furniture will look from outside, too.
3. Remember that too many glass walls will severely restrict possibilities for hanging pictures and other decorative works of art.
4. When you entertain in glass-lined living or recreation rooms, large
panes of glass can be distracting. During the day, people find themselves gazing out the windows instead of paying attention to the
conversation, and at night huge panes of blackened glass make certain individuals uncomfortable: they feel that they’re being
watched from the outside.
The inclination to overuse glass is especially strong on sites having
dramatic views, when the owners are naturally moved toward taking
full advantage of those views. In this situation you must be careful not
to get carried away. Instead, strike a happy balance between beautiful
views and functional rooms.
Along the same lines, in most settings (except in rural locations
where a house is tucked back from the main road), avoid an oversized
picture window in the front of the house. Such a window invariably
gets covered with drapes or blinds anyway, for privacy. When it’s not
covered, the residents feel like goldfish in a bowl. And typically, all
that can be seen through the front window is passing traffic. The larger
picture windows are far more productive when placed at the side or
A HOUSE DIVIDED
back of the house, facing a private patio, terrace, yard, or other more
intimate and less “public” views.
Built-Ins
To make for a more aesthetically pleasing appearance, it’s wise to
include sufficient built-ins for living and recreation rooms, especially
to accommodate the items you want to store there. Books, records,
mementos, knickknacks, card tables, and even fireplace wood are a
few common objects to keep in mind.
Built-in bookcases and shelves are installed most efficiently when
the carpenters and woodwork stainers are putting up the rest of the
house trim.
Patios
Another recreation space to consider when planning a new house
is a patio. Because it can easily become an important part of your home
living experience, a patio deserves the same careful thought that goes
into the arrangement of your interior living and recreation areas.
When pinching dollars, settle first for the foundation and concrete
slab, and plan to add a roof, privacy screen, and other conveniences
later. Location is a major factor for enjoyment of an open or screenedin patio or deck. Remember that an open concrete patio can get as hot
as a city street when it bakes in the sun.
Other Living and Recreation Rooms
Rooms sometimes built into a house are a library, den or study, and a
music or other hobby room. There are darkrooms for amateur photographers, billiard rooms for would-be Mosconis, sewing rooms, trophy
rooms, and rooms designed specifically for personal computers and
video games. These are special areas in a house which, depending on
the interests of you and your family, can greatly enhance the total living
experience.
FOOD PREPARATION SPACE
For the bachelor who scratches his head in bewilderment while
attempting to boil water for instant coffee, a kitchen complete with the
appliances of his dreams might consist of a frost-free refrigerator, a
9
10
WHAT TO BUILD
microwave oven, a double-slotted toaster, and the plainest of sinks.
Others, individuals who fancy themselves a step or two below awardwinning French chefs, need wide expanses of counter space, double
ovens, microwaves, electric grills and barbecues, three-tubbed stainless steel sinks, boxes of hand appliances, and piles of pots, pans, and
multipurpose utensils.
Food is always being highlighted by the media. Sales of cookbooks
and culinary magazines have reached best-selling proportions. Talk
shows serve up celebrity cooks. Medical studies stress how a healthy diet
can ward off heart disease, stress, and even cancer. And there’s no denying that everyone has to eat. It’s not something we can elect to pass up.
In any household, the primary food preparation area is the kitchen.
Kitchen Size
The overall size of your kitchen should depend on the following
points:
1. The size of your family and the number of individuals in your family who like to cook. Usually, the bigger the family, the bigger the
kitchen. And don’t exclude the children. Psychologists say that
youngsters, especially teenagers, should be encouraged to learn
how to cook, and that culinary creativity helps a child’s overall
development.
2. Do family members and many friends and guests tend to congregate
in the kitchen? Then make the kitchen large enough to accommodate plenty of seating space.
3. Do you approve of or insist upon having meals other than breakfast
in the kitchen? If you prefer nightly suppers in the kitchen, then
you’d better plan an eat-in kitchen arrangement, with space for a
table and chairs. If only breakfast will be served there, then a bar at
which three or four people can comfortably sit is likely to be all the
eating space you’ll need.
4. What are your shopping habits? If you prefer to go long periods of
time between shopping, you’ll need ample storage space for canned
or packaged goods, as well as a roomy refrigerator and probably a
separate freezer. Additional base and wall cabinets might be necessary, and an extra-large food pantry is a must. On the other hand, if
A HOUSE DIVIDED
your total food and beverage inventory at any one time is likely to
consist of a six-pack of beer, a quart of buttermilk, and a few frozen
TV dinners, you can get by with a lot less kitchen.
5. You might want to install a small built-in desk in the kitchen, for
making out shopping lists, menus, recipes, phone call messages,
and financial records. Or taking this a step further, consider an
equipment desk with a computer, printer, and storage files for keeping in touch with children and your cooking while “working” on
the Internet and accomplishing desk work. Many dandy recipes are
available via the Internet, which will work out handily from this
location. A broom closet keeps long and bulky brooms, mops,
sweepers, and ironing boards out of sight in case your house doesn’t include a first-floor laundry or utility room.
6. While it’s true that a family’s kitchen should be a direct reflection
of how much that family likes to cook (Why have a big kitchen if
you spend most of your time in fast food restaurants?), it should
also be an indication of what kinds of cooking are preferred. A lot
of baking encourages the installation of double ovens. In fact, if you
have the room, consider leaving space in the form of cupboards for
a second oven just in case a future potential buyer of your house
finds the ability to have a double oven an attractive feature. If you
do a lot of entertaining, plan for an indoor grill or barbecue. If fancy
presentations are important to you, select any of the other truly
marvelous food preparation aids available. Even simple items such
as brackets and shelves for condiments and spices, and bookshelves for cookbooks should be carefully planned in advance so
enough space is allowed. These built-ins might seem minor, but if
you just ignore their placement until everything else is completed,
you’ll be hard-pressed to neatly accommodate them. Finishing
touches are often what separates the attractive, efficient kitchen
from one that’s awkward to work in and always appears cluttered.
Kitchen Functions
No matter what overall size your kitchen is, it still should:
1. Provide adequate working space. Any kitchen can be thought of as
a combination of three work areas (Fig. 1.2). The first is food
11
12
WHAT TO BUILD
F I G U R E 1. 2
A kitchen work area.
preparation, which includes counter space, utensil storage drawers and cabinets, places to store cutters, knives, food processors,
chopping boards, glassware, cups, and plates. The second is food
cooking, which includes the range, oven, counter space, and storage areas for pots, pans, cooking utensils, seasonings, ingredients,
and other cooking supplies. The third is food cleaning, which
includes single or dual basin sinks, counter space, dishwasher,
trash facilities, and perhaps a garbage disposal.
Even the smallest kitchens should be set up so that the items
stored at each work area are used for corresponding activities. For
instance, the groceries should be stored near the refrigerator, so the
sandwich maker has easy access to the peanut butter, jelly, bread,
and milk without walking all over the kitchen. Likewise, cooking
utensils and aids are best kept by the stove. Cleaning supplies and
pot scrubbers should be stored within reach of the sink.
2. Provide sufficient counter space. Counter space at both sides of the
sink is crucial. At least three linear feet of counter should be
installed between the sink and refrigerator so that you can remove
food from storage and put it away with ease, and can cut and chop
foods or roll out dough. The counter space between the sink and
refrigerator is often called the mix center. Near the sink, you need
one place to stage dirty cookware and dishes before you rinse and
wash them, and another to let them dry off after washing. Sink
counter space is still a requirement even if you plan to have an
automatic dishwasher.
A HOUSE DIVIDED
The range or cooking center should also have counter space on
both sides so you can place prepared foods in one place before
cooking and afterwards in another while cooked foods are cooling.
People frequently don’t allow enough counter space here, and family cooks are sorry later on.
Beyond these areas, there should be enough additional counter
space to accommodate all your favorite items and appliances such as
a mixer, blender, food processor, toaster, crockpot, microwave oven,
electric sharpener, can opener, bread box, and even a telephone.
3. Provide ample storage space. In the kitchen, enough storage space
can mean the difference between a food preparation area that’s easy
to organize, easy to work in, and easy to keep clean—or an area
that’s difficult to work in and always a mess. Neatness and cleanliness count heavily toward a cook’s efficiency and enjoyment of his
or her work. And it’s a proven fact that substantial psychological
stress occurs to people who occupy cluttered, disheveled areas.
Here are a few points to keep in mind when planning your kitchen
storage:
■ All kitchens should contain cabinets beneath the sink to hold
items such as soaps, cleaning utensils, washcloths, and drying
towels. If you desire, a garbage disposal can make short work of
most food waste and scraps, and an automatic dishwasher can
be installed under one side of the sink counter to take care of
dirty dishes, pots, pans, glasses, and utensils.
■ There should be a good supply of cabinets and drawers around
the food preparation area for utensils, cutters, chopping boards,
and glassware. The range and cooking center also requires cabinet space on both sides for pots, pans, dishes, trays, casserole
dishes, strainers, and dozens of miscellaneous objects.
■ A pantry is a helpful addition for storing food, beverages, liquors,
a stool, and even a small sweeper for quick cleanup (Fig. 1.3).
■ After making sure you have sufficient base and wall cabinets,
drawers, and pantry space, give careful consideration to the size
of your refrigerator and freezer units. Analyze your shopping
habits again, and plan to purchase large enough refrigerators

and freezers so you won’t find yourself short of storage space
for cold and frozen foods. Do you like to hunt and fish? Is one
of your hobbies picking farm-fresh fruits and vegetables? Do
you raise your own bumper crops, or prefer to buy meats in
bulk?
■ Have an efficient layout. There are four widely accepted
arrangements of the three kitchen work centers: the U-shape, the
L-shape, the parallel wall, and the one-wall.
THE U-SHAPE
With this plan the sink is usually placed in the center leg of a Ushaped counter, between the food storage and cooking centers. The
work triangle consists of three relatively short and equal-length distances. This, plus the fact that no through traffic interferes with the triangle, is what makes the U-shape plan the most efficient and desirable
arrangement for many kitchens. It’s compact, step-saving, and keeps
the cooks out of the limelight (Fig. 1.4).

A U-shaped kitchen.
15

WHAT TO BUILD
F I G U R E 1. 5
An L-shaped kitchen.
THE L-SHAPE
This arrangement fits well on two adjacent walls and provides a
good location for dining or laundry space on the opposite side of the
room. It’s not as convenient as the U-shape, but it’s the next best thing.
This plan can be converted into a U-shape by the addition of an island
or peninsula section of counter and cabinet to work with (Fig. 1.5).
THE PARALLEL WALL
This arrangement has one work center on one wall and the others
along an opposite wall. If your house seems to demand a parallel wall
or “corridor” style of kitchen, take precautions to prevent kitchen traffic from interfering with the work triangle. Try to locate doors so people won’t naturally cut through the kitchen when entering or departing
through a back or side door. For the sake of whatever traffic you end up
with, this corridor between the two walls should be a minimum of 4
feet wide between facing appliances and equipment. This lets two people easily pass each other while working. Avoid placing the refrigerator
or oven where their open doors will block off a frequently used passageway. Otherwise, a work triangle arrangement almost as efficient as
that of a U-shape can be constructed using this plan (Fig. 1.6).
A HOUSE DIVIDED
F I G U R E 1. 6
A parallel kitchen.
THE ONE-WALL
One-wall kitchens are best suited to small houses where space is
extremely tight. At best, cabinet and counter space is minimal, and
you have no choice but to live with relatively long kitchen traffic patterns. However, if the distance from one end of the cabinetry to the
other is close to 10 feet, some degree of efficiency can be realized
through carefully laid out appliances, even when a true work triangle
is lacking (Fig. 1.7).
F I G U R E 1. 7
A sidewall kitchen.
17
18
WHAT TO BUILD
The same traffic precautions that apply to the parallel wall kitchen
also pertain to the one-wall plan.
Any kitchen arrangement can be further improved upon or detracted
from by placement of windows and doors. Effective lighting over the
sink and main work surfaces is essential. Whenever possible, place a
window that opens easily over the sink, for light, ventilation, keeping an
eye on children, and even to provide a view to make washing dishes
more palatable. Naturally, an electric light is still needed for night work
at the sink.
Doors should encourage traffic to go around the kitchen work area
instead of through it. This minimizes interruption of the cooks and the
possibility of spilling hot foods on innocent bystanders. The work area
should also be out of the way to individuals who enter and exit the house
from the rear or side, and should not be directly adjacent to kitchen
tables and chairs.
Other points to think about when planning the kitchen include:
1. Someone will be spending a lot of time in the kitchen. Try to arrange
the nicest views available through the windows or sliding doors.
2. There should be an exhaust fan or range hood with a built-in fan
directly over the range. You need a way to expel cooking smoke,
fumes, and odors to keep your kitchen fresh.
3. Plan for plenty of electrical outlets along the kitchen walls and
counters. It’s frustrating not to have enough outlets for the standard
complement of kitchen appliances.
4. Be aware that because a kitchen is considered the heart of any
household, it’s best situated in a central location, close to dining
areas and family entrances near the garage so groceries can be easily carried into the house. If you plan a family room, consider having it adjoin the kitchen along one wall to facilitate traffic,
communications, and even the ability to spread out if ever you
throw a sizeable party.
DINING SPACE
People have all kinds of theories on what dining should be. Some
individuals prefer to dine on the run, and aren’t particular about what
A HOUSE DIVIDED
they eat, where they eat, or even how the food tastes. To them, eating
is merely a necessary fact of life, a biological requirement.
Others enjoy taking the time and effort either to prepare or seek out
gourmet-style meals. Good meals to them are to be slowly savored in
the company of others, in carefully structured atmospheres at home or
in fine restaurants.
A typical household leans toward a happy median between the
“fast-food” meal and a candlelit dinner. That’s why there are often two
dining areas in a typical home—one for quick breakfasts, lunches, and
children’s meals, and another for more formal dining, which, though
less frequently, still plays an important role in holiday celebrations
and special family events. In any event, a dining room should have
direct access to the kitchen.
In many households, a third dining area consists of an outdoor patio
or deck with a gas grill. All three areas, however, should be located near
the kitchen food preparation site for greatest convenience.
You have several basic choices to make when deciding upon informal and formal dining space: quick, easy meals and snacks can be
served either at an attractive utilitarian bar, which is simply an extension of the kitchen work counter, an overhanging portion of counter
that can accommodate three or four bar stools (Fig. 1.8), or a table/
chairs or booth/bench arrangement included as part of an extension of
the kitchen—often referred to as a breakfast room or nook.
If you don’t want a formal dining room, you should probably opt
for a table/chairs set that’s placed right into the heart of the kitchen,
yet out of the cook’s way. This arrangement is referred to as an eat-in
kitchen. Formal meals can still be served in an eat-in kitchen when
special attention is given to items such as appropriate lighting, ventilation, and mood music.
The kind of kitchen dining space you prefer also depends on if you
plan to use the table, booth, or bar for other purposes. Certainly, you can
hardly play cards at a breakfast bar.
If you want more than a breakfast bar and eat-in kitchen, and you have
the space and resources, then go with a formal dining room too. This can
be footage borrowed from a living or family room, often delineated by special interior decorations or furnishings such as vinyl flooring, wallcoverings, or a chair rail. Or it could be a separate room of its own.
For ultimate privacy, doors can be installed to completely close
off the dining room from the kitchen and living or family room. This

can come in handy for special events such as birthday or graduation
celebrations.
A dining room implies both enclosed space and service at the table.
For this you’ll need plenty of table space, chair space, access and serving space, plus room for any china hutch or side table server you want.
When laying out your dining room, consider space for extra furniture
and guest seating. One way to achieve this is to have the dining room
connected to the living room (or family room) area. This will make the
home seem larger and allow for relaxed seating before and after dinner.
Also, in case you need to expand the dining room table for extra seat-
A HOUSE DIVIDED
ing, furniture could be arranged for temporary dining-table expansion.
A chandelier or other suspended lighting fixture, preferably one controlled by a dimmer switch, makes a lot of sense. The ability to lower
the lighting level, at little cost, will provide a relaxing and classy
atmosphere.
While a separate formal dining room is more traditional, an openstyle dining room can fit nicely into an active family’s lifestyle. Without the walls of a formal dining room, communications between the
kitchen and living or family room are greatly improved. And due to
the additional cost of a separate dining room, plus the overall reduction of square footage in many of today’s modern houses, the openstyle dining room situated directly between the kitchen and living or
family room is becoming increasingly popular.
BATHING AND WASHING SPACE
Three questions must be addressed when you consider the bathing,
washing, and comfort facilities you want in your new house: Are there
enough bathrooms planned? Are the bathrooms large enough? And are
the bathrooms conveniently located?
Are There Enough Bathrooms?
We’ve come a long way since the days of an outhouse behind every
barn. Today, even a house having one complete bathroom is considered old-fashioned.
It’s tempting to trade away the relatively high cost of bathroom construction and the space bathrooms require for more living and work
space. But as it is, to ensure a good market value for your house, you
should seriously consider at least two bathrooms, and possibly more if
you have a large family.
Bathrooms come in both full and half sizes. A full bath includes a
toilet, hand sink, bathtub, and/or shower (Fig. 1.9). Most modern premolded units combine a bathtub and shower in the same piece. A half
bath consists of a toilet and hand sink (Fig. 1.10).
To begin with, one full bathroom should be designated for general
use, close to the bedrooms. It should be accessible from most areas of
the house and should not be reached by traveling through other rooms.
A second bath, often directly adjacent to or back-to-back with the main

bath so plumbing fixtures can be shared, is usually located next to a
master bedroom. A third bath, or at least a half bath, can be a great convenience, especially when positioned near the living room, family
room, and kitchen.
With the exception of single-level ranch houses, it is definitely a
plus to locate a bathroom on each living level. This results in time and
energy savings over the short and long runs. If there’s one thing that
A HOUSE DIVIDED

can make a house feel too small, it’s standing in line in the morning, waiting to use
the only bathroom.
Are the Bathrooms Large Enough?
All bathrooms should be large enough
for ease of movement, proper traffic flow,
and plenty of storage. Individuals who frequently get dirty at work or at play need
roomy bathrooms with easy-to-clean surfaces. So do families with lots of children.
People who depend on their appearances,
such as models, airline attendants, politicians, salespeople, businesspeople, and
others, might also prefer more spacious
personal care areas with generous vanities, wide mirrors, and plusher appointments.
No matter what size full and half bathrooms you decide upon, all the required
fixtures and accessories should be provided and sensibly located:

■ Built-in storage for towels, soap, toilet
paper and tissues, shampoo, and other personal aids should be
included.
■ A roomy vanity and medicine cabinet rounds out the basic
storage.
■ Many clever and attractive shelving arrangements consisting of
materials from woven reeds to glass and chrome can be custom
installed into otherwise unusable space.
■ A laundry hamper or built-in laundry chute will save many
steps and will help keep bathrooms neat and uncluttered.
■ When no window space is available, a ventilation fan unit can be
installed to ensure a turnover of fresh air and prevent stuffiness.
If a window is used, though, the bathtub should not be placed
beneath it. Sufficient lighting is important, and so is a heat vent.

WHAT TO BUILD
Are the Bathrooms Conveniently Located?
In addition to being located near the bedrooms, bathrooms should
also be planned near the main floor living and working areas. If your
family often engages in outdoor activities, at least one half bathroom
should be placed near the outside access. That same half bath can then
be used by guests and family members who congregate in the living or
family room, and by individuals coming from the kitchen and dining
areas. This half bath is a real step-saver, especially in a sprawling singlestory ranch home. And remember, people—especially guests—should
be able to use the bathrooms without being seen by everyone else.
The nearer to other plumbing lines you can locate the bathrooms,
the better. Placing two baths back-to-back saves on the installation
labor and material costs and takes up a minimum of space. So does situating rooms containing plumbing fixtures as close as possible and
practical to where the sewer and water lines enter the house—this
effectively reduces the length of indoor service piping and allows for
fixtures to be drained and vented with a single stack.
SLEEPING AND DRESSING SPACE
We spend practically a third of our lives in bedrooms. When examining how bedrooms will fit into your new house, six factors should be
given careful attention: size, layout, windows, closets, noise, and the
importance of having a master bedroom.
Size
There should be a rhyme and reason for bedroom sizes. Look at
each one separately. Will it be for children or adults? Do you want
bunk beds or queen- and king-size versions? Will a spare bedroom
also serve as a sewing room? Are you planning a master bedroom
complete with its own bath? In addition to providing space for beds,
bedrooms should be able to comfortably accommodate a small desk, a
dresser, and other clothes storage areas. Children’s bedrooms should
have suitable space for doing homework, for a desk, computer, computer stand, and printer. They should also contain storage shelves and
sufficient closet space. There should also be enough room for dressing
and personal care, and ample window space to provide sufficient air
and natural lighting.
A HOUSE DIVIDED
Layout
There are no tricks to designing functional bedrooms, but a frequent mistake is to have a poor bed location in relation to the bedroom’s traffic pattern. Because bedrooms usually have at least several
doors—the entrance door from a hallway, closet doors in various
arrangements, and possibly a door to a private bathroom, dressing
room, or even to an adjoining child’s nursery—these entranceways
make continuous wall space for furniture, including the bed, hard
to find.
Typical bedroom traffic patterns are from the main bedroom door to
the bathroom, clothes closet, or dresser, in that order of frequency. If
you have to walk around the end of the bed to reach any of these
places, you’ll have an awkward traffic pattern. When laying out each
bedroom make sure there’s a place to locate the bed or beds that won’t
result in the creation of obstacle courses.
An unused “secondary” bedroom is ideal for guests. If you expect
frequent visitors, consider equipping such a bedroom with an attached
bath for privacy. Try to have the heating and cooling for this bedroom
zoned for energy savings.
Windows
Bedroom windows, like most other windows, have two primary
functions: to provide light and ventilation. Windows are helpful both
in cool climates where they let the sun in to illuminate and heat bedrooms (although windows can also be mediums of rapid heat loss
when the sun is absent), and in warm climates, where windows on
opposite walls provide refreshing cross ventilation breezes. At the
same time, heavy-duty window shades or coverings can be used during the day to keep out hot sunrays. In unusual circumstances, when
only inside walls enclose a bedroom, the need for cross ventilation can
be negated by the installation of central air-conditioning.
When considering the style, efficiency, and placement of bedroom
windows, think about the possibility of drafts during cold weather,
especially at the head of a bed placed near a window. On the other
hand, such drafts can become cooling breezes welcome on hot summer
evenings. Weigh the pros and cons and remember that certain types of
windows positioned over the head of a bed might be difficult to open
or even reach.
25
26
WHAT TO BUILD
After deciding on the types of windows you want, make sure they’ll
provide adequate safety, including an escape route in case of a fire. In
a child’s bedroom, you won’t want windows so low that you’ll have to
worry about children falling out of them. But if the windows are too
high off the floor, or too small, then the kids can’t reach or escape from
them during an emergency. All sleeping areas should have at least one
easy-to-open window with an opening of not less than 7 square feet.
Check local building code requirements for window opening width
and height, as well as the sill height above the floor. All window locks
should be able to be unlatched quickly so a child or adult needing to
exit for a fire is not delayed.
Closets
Closet space is vital to any bedroom. Without closets, orderly
clothes storage becomes impossible. In fact, even individuals living in
houses with an abundance of storage space always seem to want more
closet room as the years go by and possessions keep accumulating.
To head off what could be an eventual problem, plan generous closets that make the most of their space. Consider going with a splitdesign version: half of it open all the way up so dresses, raincoats, and
other long garments can be hung, and the other half consisting of two
double-decked pole and shelf arrangements, for shorter garments.
Small items can be placed on shelves installed in what otherwise
would have been wasted space within conventional closets. Many
people are surprised when they learn how much a scientifically
designed closet can neatly hold (Figs. 1.11 and 1.12).
For sheer convenience, there should be an inside light in every
closet; not one operated by a pull string. Install an electrical switch
either inside or outside the closet doors. Pull strings and chains have
a way of getting tucked up on a shelf as something is being put away,
then they become difficult to find in the dark. Don’t use a bare lightbulb without some kind of glass cover. There’s a danger of fire if the
bulb is not at least 18 inches from the edge of the nearest shelf or from
the closest item of clothing. A better alternative is to install recessed
lighting in all closets.
Last, if you choose not to store extra replacement linens in a bedroom closet, see that storage for them is available in a different closet
located close to the bedrooms, perhaps in a hallway.
A HOUSE DIVIDED

Noise
As a rule, bedrooms should be placed together in a part of the
house that’s protected from outside vehicle noise from nearby
streets. As much as possible, they should also be secluded from living, entertainment, and working space noise inside the house. Some
dwellings lend themselves to a clear-cut separation of sleeping

space: two-story homes, for example, usually reserve the second
floor for bedrooms. This clustering of bedrooms, generally near bathroom facilities, makes parental supervision easier and ensures a
quiet sleeping area.
The Master Bedroom
The term “master bedroom” sounds like a throwback to medieval
times, when the master and mistress of the house lived out their lives
A HOUSE DIVIDED
in luxury, catered to hand and foot by indentured servants. Today, a
master bedroom is one common luxury item that most homeowners
still enjoy. A master bedroom offers the utmost in convenience and
privacy; it should at the very least include a half bath (a full bath is
much preferred), and should be large enough to permit several alternative furniture arrangements. Include enough uninterrupted wall
space for a queen- (or king-) size bed.
As mentioned before, the clothes closet should be roomy. Two separate closets—“hers” and “his”—are ideal. The closets should have a
minimum depth of 24 inches. The poles should have a height of
between 5 and 6 feet and be at least 12 inches from the closet rear wall.
If hanging poles are to be double stacked, the top pole should be
installed at least 6 feet high. It’s also a good idea to soundproof the wall
between the master bath and master bedroom for the late-sleeping/
early-rising couple.
SERVICE AND STORAGE SPACE
There’s nothing glamorous about service and storage space. You
can have spectacular living rooms for talk-of-the-town entertaining,
modern kitchens that grace the covers of architectural magazines, luxurious master bedrooms, and spacious whirlpool and sauna bathrooms for pampering yourself. But who can get excited about hallways
or stairs? Or laundry and utility rooms? Usually the homeowners who
have ill-planned ones.
Certainly these behind-the-scene features cannot be excluded from
the typical house. Storage areas are also necessary accompaniments to
the more popular parts of every dwelling. They include closets, small
storage nooks and crannies, plus garages, basements, and attics.
Hallways
There’s something disconcerting about a main entrance that opens
directly into your living room. Instead, look for a center hallway plan
that offers access to any part of the house without leading you conspicuously through living and entertainment areas. On the other hand,
excessive hallway footage, along with its special walls, means costly
wasted space. To limit the space used by an entrance hall, make the
entry a part of a corner of your living room, but still keep it “separate”
29
30
WHAT TO BUILD
by installing a different flooring and by breaking up the ceiling line
directly above the change of flooring.
Instead of completely writing off necessary hallway space as practically useless except as a pathway between rooms, consider the wall
surfaces as potential showcases for artwork and photos. Strategically
located lighting fixtures will also help support an individual decorating effort. Where needed, specify 42-inch-wide hallways when possible. They make carrying large pieces of furniture safer and easier.
Stairways
This kind of house space has had its ups and downs over the years.
Wrongly positioned, stairways—like hallways—can rob otherwise
useful living and working space from any floor plan. To avoid this
wasted effort, stairways should be constructed one on top of another
whenever possible.
Even though you’ve probably heard a lot of nice things about the
spiral stairway, don’t believe all of them. Although this setup, which
takes approximately 4 by 4 feet of floor space, is the most compact
arrangement you can have, it’s also the most expensive, inconvenient,
and dangerous. The novelty quickly wears off. Ask anyone who has
had to raise children around a spiral.
The most economical and convenient choice is a standard straight
stairway taking up about 8 by 3 feet of floor space. An altered version
of the straight stairway that can be very acceptable is the landing stairway, consisting of a half flight of stairs that leads to a rectangular landing and then another half flight to the next floor level. The landing
stairway takes up about 7 by 7 feet of floor space. It adds an extra touch
to a room at a cost higher than that of a straight stairway, but without
the hazards of the spiral.
When planning a basement, consider the practical advantages
gained by an outside stairway. Bulky items can be carried from the
back or side yard to the basement, and vice versa. This also increases
the likelihood that you’ll use your basement for storage instead of just
dropping everything in the garage.
Laundry and Utility Rooms
Mention “laundry room” as a topic of conversation to anyone and
you’ll likely receive a polite nod and a yawn. Most home buyers tend
A HOUSE DIVIDED
to overlook the importance of both laundry and utility rooms because
these areas simply don’t have the pizzazz potential of other parts of a
house. That’s unfortunate. Laundry and utility rooms haphazardly
planned are usually tucked somewhere out of the way, with little consideration for convenience.
There are two kinds of utility rooms: those with laundry facilities
and those without. Utility rooms without laundry facilities can be
located practically anywhere toward the outer reaches of the central
living and work areas of the house. Utility rooms having laundry facilities must be positioned more carefully and can be located successfully in a number of places within a house.
A basement is one locale. This can be an economical place, although
over the years you’ll have to contend with constant stair climbing. If
you decide on the basement as your laundry/utility area, give serious
thought to a direct outside basement access (Fig. 1.13). A door to the
yard lets you hang clothes outside during nice weather. It also lets you
enter from the outdoors in wet or dirty clothes that can be changed
right in the laundry area. Then you simply wash up at the laundry tub
and proceed through the house. A clothes chute from the upstairs levels to the basement laundry basket can be another step-saver.
A garage or carport is another locale. In warm-climate locations
people often choose to put their utility room either in the garage/
carport or in an adjoining space called a “mud” room—so named
because of its outdoors accessibility. There are no steps to climb (or
very few), and with a laundry tub you can enjoy all of the conveniences
found in a basement utility room having direct access to the outside. If
there’s a second story in the house, a laundry chute can be arranged to
drop clothes straight into a garage or carport or mud room hamper.
The first floor of the house is yet another alternative. There are two
types of in-house laundry rooms that can be positioned on the first
floor of any house. First, there’s a laundry room that’s a full-size room
a little smaller than the average bedroom but large enough to hold
a washer, dryer, stationary tub, ironing board, soap, bleach, cleansers,
a sewing machine and supplies, and, if enough space is available, a
working surface for sorting clothes before and after washing, drying,
and ironing (Fig. 1.14). There should also be a clothes closet with floor
space for storing dirty laundry out of sight. The closet should have
shelves for laundry sprays, softeners, measuring cups, and scrub

brushes. Consider having the clothes rod go only three-quarters across
the closet, so one-quarter of the vertical space can be reserved for
shelves affixed from top to bottom.
The second type of first-floor in-house laundry room is a laundry
center that’s installed entirely within a closet (Fig. 1.15). This is a more
economical route than the full-size room. Although you don’t have as
much space or versatility, you do have the basic necessities for washing clothes in a first-floor location. The closet in question need be only
as deep and as wide as required to accommodate a washer, dryer, and
stationary tub. A shelf across the top of the appliances can hold laundry baskets, soap, and other items. You might have room to stand up
an ironing board, too. If not, just place it in a kitchen broom closet. A
screen or folding louvered door should be installed to conceal the
laundry center when no one is using it. This setup is clean, simple,
and convenient.

When possible, try to have one of the
first-floor laundry arrangements. They’re
usually the best alternatives and have the
most conveniences.
Once you decide on the size and type of
first-floor laundry you want, a number of
other things must be considered when
you’re planning its location:
1. If it’s situated near an outside door,
you’ll save wear and tear on carpeting.
Someone walking into the house after
playing football in the rain, jogging, or
fishing can easily change clothes and
clean up before trooping through the
rest of the house. An outside access
also makes it easier to hang clothes in
the yard.

WHAT TO BUILD
2. The nearer the kitchen, the better. Clothes washing can be made
much more palatable when done in between other tasks. If the laundry is close to the kitchen, you can move from one area to another
with ease and accomplish more work in a shorter timespan.
3. If you plan your house so the main bath and bedrooms are on the
same floor as the kitchen, consider locating the laundry between
the main bath/bedrooms and kitchen. Again, being near the
kitchen will allow you to move easily between those work areas.
Being near the main bathroom will save steps when collecting
soiled clothing. And being near the bedrooms will make it simpler
to put away clean clothes. If you plan a two-story house with the
main bath and bedrooms on the second floor, try to include a
clothes chute that will usher soiled clothes straight into the laundry room collection hamper.
4. It’s nice to have a window in the laundry for the daytime sun. If
you can’t arrange one due to your layout (for instance, if you have
room for only a hallway closet–type laundry center) then make
sure you plan for adequate lighting. Working in the dark causes
eyestrain and general fatigue.
5. The ideal laundry room should provide storage space to accommodate the following:
■ Soiled clothes. Preferably more than one container so clothes
can be sorted as they accumulate.
■ Detergents, bleach, sprays, iron, and related supplies. Be sure
they are out of children’s reach.
■ Space/shelves for folded clean clothes. Preferably a section for
each family member.
■ If the room is large enough, an ironing board and sewing
machine.
■ A place to hang clothes, especially permanent press items.
6. If you have enough room a conventional standup ironing board
will do fine. However, even if space isn’t a factor, one arrangement
to consider is a built-in ironing board (Fig. 1.16) that hides or folds
into a wall when not in use. These ironing boards are usually
strong and durable, and between 40 and 48 inches in length. The

units can be recessed into a wall or simply attached to it. The foldout ironing board is especially handy when you have to press one
or two garments in a hurry. Ironing centers can be purchased with
a variety of features, including:
■ Unfinished wood cabinet doors, allowing you to stain, paint,
or paper them to match a room’s decor. A fully mirrored door
is another alternative.
■ Storage shelves. In some there’s a special shelf for an iron to
rest on, and it’s constructed so you can put the iron away
immediately after use, with no cooling required. Other shelves
are arranged to hold spray starch, water bottles, hangers, and
similar items.
■ Automatic iron shutoffs. They’ll turn off your iron if you for-
get. A timer is set when you begin to iron, for up to 60 minutes.
If you’re called away and cannot return before the 60 minutes
35

WHAT TO BUILD
are up, a red light will come on and the iron is automatically
turned off. You simply reset the timer when you return. Look
for a unit with a safety switch that turns off the electricity to
the ironing center when the ironing board is put into its storage
position.
■ Adjustable work lights. A built-in work light that swivels up,
down, and sideways to provide illumination exactly where
you need it.
■ Hanger hooks. For just-ironed garments. The hook folds flat
against the door when not in use.
■ Swivel units. Some ironing centers have ironing boards that
can swivel a full 180° to face whatever direction you wish.
This adds greater installation flexibility. An unusual room
design or the location of furniture in the room can usually be
accommodated by swiveling the board one way or another.
■ Optional sleeve boards. This affords about a 4-inch clearance
between the board and base, allowing room for maneuvering
and arranging garments while ironing. They’re great for ironing sleeves, pant legs, pleated garments, and baby clothes.
7. Double-stacked clothes washer/dryer arrangements can be used
when space is at a premium. Improved design has resulted in
narrower units that can be located in places previous models
could not. A variety of excellent 24-by-24-inch stackable washers and dryers are available. If you can live with the smaller
capacities, they can be placed in a closet 30 inches wide by 30
inches deep. Necessary sprays, spot cleaners, and detergents can
be kept in the same closet or in a nearby cabinet. One company
makes a standard-capacity washer/dryer unit that can be placed
side by side separately or doublestacked. This is an ideal option
if you need large-capacity washing but still want to save space by
stacking.
The nice thing about double-stacking is that the clothes washing and drying machines can actually be located in a space comparable in size to an entrance hall closet.
8. A stationary sink located near the clothes washer will save a lot of
steps. It’s handy for a variety of tasks:
A HOUSE DIVIDED
■ Pre-machine washing
■ Spraying spot remover on garments
■ Soaking items
■ Drying items
■ Filling pails with water
■ Cleaning and spraying houseplants
■ Cleaning and rinsing off large items such as boots
Stationary sinks come in a variety of materials, including plastic, fiberglass, steel, and stainless steel. You’ll find the plastic
models to be extremely efficient and economical.
9. Clothes chutes and hampers can be an important part of the laundry center. The use of a clothes chute will save labor and time in
getting the dirty clothes to the washer. Simplifying this task will
encourage everyone to properly dispose of the items to be washed
instead of leaving them all over the house.
In addition to keeping the dirty clothes out of sight, hampers
can be an attractive addition to the hallway or bathroom decor.
Their style and shape can vary from a rectangular floor model to a
bookcase-style stand-up model with adjustable shelves, an overhead cabinet, and a tip-out hamper on the bottom.
The most popular hampers are made of machine-washable fabrics such as cotton and polyester, supported by a hardwood or
brass-plated steel frame. Hand-woven rattan or willow strips are
also very serviceable. If space permits, two separate hampers can
be used, one for whites, and one for colors.
10. One drawback to laundry centers can be the tangle of hoses and
electrical cords that surround washing machines and dryers. A
washing machine outlet box groups together all of the water connections, drains, and electrical outlets for both machines into one
neat, compact unit that can be almost hidden from view, recessed
into a wall. Made of molded ABS plastic, the device meets safety
standards and is available in a cream color that blends with any
laundry decor. The unit should also have a contoured bottom for
overflow drainage.
37
38
WHAT TO BUILD
11. To prevent mold and mildew from forming inside closets, make
sure clothes are dry before storing them. To help this happen, closets can be outfitted with louvered doors to provide air circulation.
As you can see, a variety of arrangements are available to accommodate your laundry center. Some are more convenient than others. No
matter where you locate it, here are a few additional considerations:
■ Make sure there is an outside dryer vent. Otherwise moisture
from the clothes dryer will cause an uncomfortable environment that’s tough on laundry machines and other appliances,
tough on the house (moisture causes mold and mildew, will
soften plasterboard, and will rust metal), and even tough on
people (it’s hard on the lungs).
■ If you’re concerned with the possibility of overflowing wash or
rinse water, have a drain installed beneath the washer. With a firstfloor laundry not set up over concrete, consider vinyl flooring so
spills can be efficiently mopped up without leaving a mess.
Garages
People who have never had a garage don’t realize what they’re
missing. They say that their cars have always been out in the weather,
and if not for a little inconvenience during winter, who needs a garage
anyway? But once they move to a place that has a garage—even a small
detached garage—they’ll never go without one again. It’s nice to get
into a dry car after an all-evening snowstorm. It’s nice to be able to pull
out of the garage in the morning and drive past the neighbors who are
stamping their feet and swearing while they scrape sheets of ice from
their windshields. And by the same token, in the South or Southwest,
it’s nice to climb into a car that hasn’t been roasting all day in the sun.
Persistent sunlight fades paint, rots fabric, and cracks vinyl.
It’s also nice to have storage space outside the house for seasonal
items that can go six months of the year out of sight secured on garage
rafters. It’s nice to be able to lock up your cars, bicycles, golf clubs,
tools, and spare tires in a garage.
When determining the size of your garage, consider how many
vehicles you have (or plan to acquire), as well as the quantity of other
items you want to store there. A roomy garage can serve many pur-
A HOUSE DIVIDED
poses other than being a car barn. Will you need additional room for
workshop or hobby areas? You’ll find a garage useful for storing
canned foods, holding garage sales, and even as a handy play area for
children when it’s raining. When designing your garage:
1. Insist on at least one floor drain. If the garage will be connected to
the house, there should be a drain under each car space. Contour
the concrete floor to the drains so the surface can be easily cleaned.
Without the drains, dirt, mud, and slush will inevitably get tracked
into the house.
2. If the garage is built under the same roofline as the rest of the house
it will simplify construction efforts and costs. The property assessment will also likely be lower with that kind of arrangement, which
will in turn minimize real estate taxes.
3. A garage should conform to the slope of the lot. If necessary, sidesloping lots can be accommodated by lowering the garage to meet
the natural lot line, but this increases the number of steps needed
from garage to living area, and by doing so takes away from some of
the garage’s usable space. On the other hand, if the garage is located
higher on the same side-sloping lot, the driveway and garage floor
will have to be built up substantially. This will be discussed further
in chapter 15, on garages.
4. In warm-climate locations the garage is sometimes used to house
the furnace, air conditioner, water heater, and laundry equipment.
Whatever items you plan on installing, make sure your garage will
be large enough to carry out your designs. If you place any equipment having natural gas pilot lights in a garage, precautions must
be taken, especially if flammable liquids are stored there.
5. If the back of your fireplace will protrude into the garage, that must
be taken into account. As mentioned earlier, such a setup will save
on chimney finishing bricks, and excess heat will be radiated into
the garage instead of being lost directly outside.
6. If there’s enough room on the lot, consider having a 3-car garage.
After all, the garage is one of the least expensive parts of a house. In
addition to the parent’s vehicles, a son or daughter will often use
the third space.

WHAT TO BUILD
Basements
The decision to have or not have a basement is often influenced by
the regional custom of the area you’re building in. Most houses in
cold-climate locations will have basements. But in areas having
exceptionally high groundwater tables (swampy places, for instance)
or not experiencing freezing temperatures during winter, houses do
not need and sometimes should not have basements. In general,
though, there are a number of advantages to a basement:
1. A basement will provide handy storage space for household materials and outdoors equipment, especially when an outside access
door is installed.
2. It’s an ideal out-of-the-way place to put your water heater and furnace. Both of these appliances are simple to service and repair in a
basement.
3. A house with a basement is usually easier to protect from wooddestroying insects such as carpenter ants and termites.
4. In a basement, water pipes are less likely to freeze, and wiring and
all piping installed beneath the house are easy to get at for repairs
and modifications.
5. A basement offers economical potential for future living expansion.
A family room, bedroom, sauna, bathroom, workshop, darkroom,
or other hobby and game room can be neatly situated within a basement. Consider a 9-foot-high basement for easier finishing later.
Some people, even though they live in areas where a basement is
traditionally included with the typical house, have strong feelings that
such a feature is a waste of both money and space. They consider basements as dark, dank areas suitable for merely storage and the housing
of a furnace and water heater. Here are some frequently mentioned
drawbacks to having a basement:
1. The necessary stairway encroaches on usable space both in the
basement and on the floor above.
2. There’s no doubt that basements can be dark, gloomy, wet, and
clammy.
A HOUSE DIVIDED
3. There’s an expense for waterproofing and establishing proper
draining around the foundation.
4. There’s also the cost of basement flooring, finished walls if
desired—plus heat, wiring, and lighting.
5. If the money spent on the basement could be used elsewhere, you
could substantially add on to your upstairs living levels.
6. Unlike the rest of the house, the typical basement has little natural
light or ventilation.
Attics
Here’s a house feature that appears to be nearing extinction, going
the same way as the covered sitdown front porch. Years ago, when
two- and three-story houses were crammed together along big city
streets like upright dominoes, attics were included with every
dwelling.
They held (and still do) old chests and cardboard boxes loaded
with Christmas decorations, clothes, toys, school papers, books,
antiques, and other mementos. Attics have always been cluttered,
dusty repositories of family memorabilia—mostly because there was
little other space built anywhere else into the house for storage. If you
happen to decide on an attic, remember:
1. Although the attic opening should be located in a concealed, outof-the-way area, it should be easily accessible when you have to use
it. A good place to put a pull-down stairway unit is inside a utility
room or spare bedroom closet.
2. The attic opening should at least be 23 ⫻ 54 inches. Don’t settle for
anything less than a drop-down staircase or ladder arrangement,
especially when the attic opening is situated in the garage.
3. If possible, allow for ample attic height and headroom to enable
you to move around without constantly stooping over.
4. Some individuals believe they can store items across the attic floor
joints without laying down flooring. Don’t fall for that trap. Never
settle for a completely unfloored attic. The more you lay down, the
better.
41
42
WHAT TO BUILD
5. Provide lighting and an electric outlet in the attic. Attics are generally dark inside. It’s an inconvenience having to always carry a
flashlight up there, or to string an extension cord every time you
want to use a vacuum cleaner, light, or power tool.
6. Provide ventilation in the attic to alleviate harmful heat and moisture buildup during summer.
7. If a pull-down stairway is not selected, don’t settle for a flimsy
piece of wood pulled over the attic access doorway. Instead, consider specifying a custom-made steel access door with frame, built
on hinges for ease of use. This type of door will not warp, has an
excellent fire rating, can be purchased with recessed hinges and
catches, and is fully insulated.
Storage Space
A sufficient amount of storage space will make a home a much
more pleasant place to live in. While some individuals catalog everything they own and are able to find the most obscure item at a
moment’s notice, others are so disorganized that they routinely lose
anything from their Christmas decorations to last year’s swimsuits.
The relatively recent reduction in the overall square footage of
houses has wreaked havoc with storage space and has thus increased
the importance properly designed storage space can mean to you. Efficient storage in bedrooms and kitchens is especially critical. Here are
a few points to consider when planning your overall storage space:
1. Place a clothes closet near the main entrance.
2. Have a linen closet near the bedrooms and main bathroom to hold
sheets, pillow cases, towels, washcloths, comforters, and other
bulky whites.
3. Try to place a clothes closet near the garage or side entrance.
4. Locate a pantry closet in the kitchen for holding canned foods, beverages, liquor, and lots of other kitchen items.
5. Make sure that your “live” storage—for items used day-in and
day-out—is very accessible. Live storage requires drawers,
shelves, closets, and at times, chests. Each storage area should be
A HOUSE DIVIDED
thought out in advance for particular needs and sized accordingly.
And each should be located in the proper place.
6. Your “dead” storage—for things you use only infrequently during
the year, such as lawn furniture and snow tires—can be put in outof-the-way locations. Find dead storage in the most inaccessible
spots, in places such as attics, basements, and garages. Use boxes
and chests to store smaller items in.
It only stands to reason that as far as possible, your house should
provide you with whatever you need for safety, comfort, enjoyment,
and privacy. For individuals having particular interests requiring special adaptations, facilities such as the following may be desired: a
sauna, steam bath, hot tub, greenhouse, elaborate garden, fountain,
swimming pool, place for animals, patio/garden living room, or various outdoor work and hobby areas.
No matter which areas are most important to you, make sure you at
least consider each of the six main types of spaces under roof. That
way you can make intelligent decisions when custom designing your
house, realizing the trade-off effects that having too much or too little
of any particular space are likely to have once you move in.
A house ultimately expresses the unique personalities, goals, and
lifestyles of its inhabitants. Thus, a totally satisfying residence will
provide you with deep-seated feelings of personal achievement and
will remain a source of continuous pride.
➤➤➤➤➤ POINTS TO PONDER
1. Consider that a modern house consists of six main types of
space: living and recreation, food preparation, dining, bathing
and washing, sleeping and dressing, and service and storage
space.
2. Carefully review and question your need for both a living room
and a family room. Having both is no longer as necessary or traditional as it was in past years.
3. To make for a more aesthetically pleasing appearance, it’s wise
to include sufficient built-ins for living and recreation rooms,
such as bookcases and shelves to exactly match the wood trim
that’s being installed throughout the home.
43

WHAT TO BUILD
4. Plan in advance for special needs such as photo darkrooms, a
library, den, billiard room, exercise room, or home office. They
can be special areas that, depending on your interests, can
greatly enhance the total living experience.
5. If you’ve ever heard the saying, “I hardly ever cook, so that’s
why I like such a small kitchen,” don’t believe it. The importance of counter space and storage space in a kitchen cannot be
stressed enough. Consider the value of an open connection
between the kitchen and family room. You can visit with family
members, relatives, and guests while preparing or cleaning up
food and refreshments.
6. To keep extremely messy teenagers and other so-inclined family
members out of the nice bathrooms, consider a “knockaround”
bathroom installed in the basement for those individuals to
shower in, put makeup on, and toss their dirty clothes (if there’s
a basement laundry) directly near the washing machine.
7. Many homebuilders never understand how important closets
are to bedrooms. Make them larger than you think they should
be. And put lights and sturdy shelves in them.
8. Go for a larger garage than you think you’ll need. If you’ve got
enough room on the lot, and you can make it fit with the overall
house plan, a three-car garage may not cost much more, proportionally, than a two-car garage.
9. A well-planned attic can add inexpensive storage (and sometimes expandable) space to certain types of homes, especially
when properly insulated, floored, and wired.
10. Keep in mind the value of a first-floor laundry. It will save you
time and energy when conveniently located.
CHAPTER

House Styles and Types
Y
our ideal house, a dwelling that’s both handsome and practical, is
much more than simply a collection of great rooms. Certainly, a
well-designed house that offers plenty of living security, enjoyment,
and pride of ownership should feature memorable individual rooms.
But that’s not enough.
To work as a single unit, rooms should be arranged to match your
living requirements and lifestyle as closely as possible. Your home
should contain the correct amount of space to suit yourself and your
family or future family. It shouldn’t be too small, nor too large.
The best way to go about putting a house together in your mind is
also the most logical. First, decide on the amount of space you want
roofed over. Once that’s established you can go on to the style and type
of house that will best lend itself to your objectively arrived at space
requirements and your subjectively arrived at preferences for appearance and setting. Naturally, both advantages and disadvantages exist
for all the various types of houses, and these characteristics will be
pointed out later in the chapter.
Somewhere in the back of your thoughts, while considering space
requirements and house types, keep in tune with your financial parameters. If money or income is a major problem, pay particular attention to the chapter on planning for future expansion.

WHAT TO BUILD
When deciding how much space will be roofed over:
1. Arrive at the number of rooms you want. The six types of space
were discussed in the previous chapter. Figure out your ideal number of rooms: what they are, their sizes, and then, just to be safe,
also determine the minimum number of rooms you can get along
with (keeping in mind you can add more at a later date).
2. Determine a dollar-per-square-foot cost and decide how much you
can afford or wish to spend. Consider how much of a down payment you can come up with, plus the cost of current mortgage rates
in your area. To arrive at how much you can expect to pay per
square foot of house space, attend new construction open houses
that are built with similar materials and workmanship to what
you’d consider acceptable. When at an open house, ask what the
going price for the house is, excluding the lot, then divide those
total dollars by the amount of square feet the house has. Square
footage means the livable area of the house. It doesn’t include the
garage, basement, or attic. What you can spend on a home mortgage
is usually governed by ratios of indebtedness to income that are
conservatively set by banks and savings and loans.
3. Decide on the style of architecture you’d prefer. Some styles are
innately larger than others. Some styles are low key, while others
literally exude a certain social status. Your choice is likely to be
influenced by climate, geographic location, personal tastes,
finances, and also by the dwellings already built in the area or
neighborhood you decide upon.
4. The last consideration, and a consideration more important than
style, is the type of house you want: a single-story, a one and onehalf-story, a two-story, split foyer, or multilevel.
HOUSE STYLES
Style is a broad concern that will ultimately affect your choice of
house. It most commonly indicates the decorative features of the exterior and to some degree the interior. An overview of the various house
architectural styles reveals that individual styles are best suited to
their own particular climates and locations. They’re frequently con-
HOUSE STYLES AND TYPES
structed of local or native materials, with exteriors and even appropriate colors that complement their surroundings.
When looking at particular styles you will find that Early American, Cape Cod, Colonial, Georgian Colonial, and Southern Colonial are
all styles that have withstood the whims of change. The first two are
compact, informal houses well suited to the northern sectors of the
United States. The Georgian and Southern Colonial are larger and
more formal. The Georgian is adaptable to both the northern climates
and the milder climates, and the Southern Colonial—actually a form
of the Georgian—is especially suited to the warm and humid climate
of southeastern regions. Meanwhile, the Mission or Adobe style is particularly good in the hot, dry climate of the Southwest; in the warm,
wet areas of the Southeast, adobe would not withstand a single rainy
season. The Adobe is a prime example of how house styles often incorporate local materials of a particular region.
A popular and far-reaching style that has been evolving over recent
years is the Contemporary. This style is suited to the theory “anything
goes” and has few rules to follow or break. Contemporary houses can
be simple, basic, and inexpensive. Or they can be extremely liberal in
their composition, consisting of any of a variety of singularly dominant characteristics, from long, sweeping rooflines, to a half-dozen
levels juxtaposed over one another. Contemporaries can be full of big
open spaces, constructed with huge panes of glass, hand-hewn stones,
posts and beams, and modern brightly colored manufactured materials. Innovative features such as passive solar heating, central courtyards or greenhouses, interior balconies, and spacious wood decks are
frequently part of the Contemporary plan.
But Contemporaries are not for everyone. They can mean skilled
engineering, expensive plans and drawings, tricky construction, costly
materials, and high utility bills from heating cathedral ceilings and
similar extravagant spaces.
Although individual construction styles may vary greatly from one
another, they all must answer to certain design guidelines. No matter
which style you lean toward, consider the following points in regard
to your own house plans:
1. Think about the design of your house in relation to the complexity
of construction. If the house makes a turn anywhere, for example—
47
48
WHAT TO BUILD
L-shaped or U-shaped rather than running in a straight line—you
introduce construction complications. A gable roof, which is simply
two sloped surfaces meeting at a high point called a ridge, is economical and comparatively easy to build, until you choose to turn a
corner with it; then the junction forms a V-shaped indentation and
the affected rafters require compound angle fitting, a construction
technique that takes much more time and skill. Instead of laying
down simple angles where all the rafters are positioned in the same
fashion, boards must be individually measured and cut to multiple
lengths and angles.
Another suggestion that will keep construction costs lower is to
build the outside walls free from a lot of ins, outs, jigs, and jogs
(Fig. 2.1). Most houses look better anyway if they don’t have a sizeable amount of rooflines joined together. Otherwise a house will
appear cluttered and haphazardly designed. In general, a simple
square or rectangular plan gives you more house for the money.
2. A few additional comments about the roof and roofline can be
made here: a continuous roofline gives an impression of greater
size than a roofline broken up into several different planes. A roof
should extend or overhang past the outer walls 2 to 4 feet. This not
only lends a handsome and distinctive appearance to the house,
F I G U R E 2 .1
A house cluttered with many ins, outs, jigs, and jogs.
HOUSE STYLES AND TYPES
but it also helps protect windows and outer walls from snow, rain,
and sun. Another plus is that it keeps water away from the foundation and basement. A substantial overhang is a feature largely
ignored by many builders. It shouldn’t be excluded. For the relatively small cost of an overhanging roof, there are too many benefits
to go without one.
A roof over the main entranceway will shield you from the elements while you’re fumbling for your house key, or will keep visitors out of the rain while they’re waiting for you to answer the door.
It also provides a nice spot for you to sit on a patio or lawn chair in
comfortable shade during the summer.
3. Remember that good proportions are one of the first rules of a goodlooking house. The exterior of your house should not have more
than two (at the most, four) sizes of matching windows, apart from
glass sliding doors. At the same time, the doors should not be of
abnormal size or located in odd places. To arrive at a satisfactory
scale and proportion of doors and windows, compare what’s
already been installed on existing houses in neighborhoods you’d
feel comfortable in. Get a feeling for the styles of windows and
doors you prefer.
The tops and bottoms of all equal-size windows should line up,
conforming to one long horizontal line across the house. Smaller
windows should line up with the tops or bottoms of larger windows. When the tops of exterior doors also line up with window
tops, things will look even better.
The exterior should not consist of more than two, or at the very
most three, kinds of siding materials, so that the whole appearance
works toward a single theme. If a wide variety of materials are present, the house will not be pleasing to the eye, plus the exterior will
likely end up costing more than necessary and will be difficult to
maintain properly. Never mix more than three materials such as
aluminum siding, wood siding, bricks and stone, or glass. Each will
compete with the others, resulting in an extremely “busy” and disconcerting effect.
Just as too many different building materials will clutter up the
exterior of a house, so will too many colors. You’ve probably heard
of Hollywood entertainers who paint their mansions a bright
orange or obscene purple. If you merely want a practical, hand-
49
50
WHAT TO BUILD
some exterior that won’t draw curiosity seekers and will help
ensure a good resale value, then the exterior of your house should
be consistent with the exteriors on the rest of the neighborhood
dwellings.
4. It makes sense to select a house style that will closely match the living pattern of your family. Consider your entertainment activities,
hobbies, children’s pastimes, gardening interests, maintenance
desires, and even the amount of time you like to spend away from
home on vacation.
5. If you might want to add another room or section later on, when
designing for expandability remember that building up or down is
always cheaper than building out. Also remember that building
out, if the only alternative, at a later date will be more cost efficient
if you plan for it at the outset.
HOUSE TYPES
House “type” denotes the number and arrangement of a dwelling’s
living levels. The basic types of houses are the single-story ranch, the
Cape Cod or one and one-half-story, the two-story, the split foyer, and
the multilevel.
Again, an important consideration that will affect your choice of
house type is your lifestyle. You want the house that best fits your
needs and meets your ideas of personal acceptance and preference, as
well as something that fits the setting you desire.
Some family activities that will affect the type of house you want are:
■ Entertaining—card playing, informal and formal dinners, out-
door barbecues, large cocktail parties, teenage parties, and other
pursuits all present different requirements.
■ Privacy—families and individual members differ in their desire
and needs for privacy.
■ Hobbies—these can present special problems related to space,
storage, and noise levels. For example, a drummer needs a different kind of space than a stamp collector. The woodworker
needs room for bulky tools and materials and will be a major
generator of noise.
HOUSE STYLES AND TYPES
The Single-Story Ranch
This type of house (Fig. 2.2) can be constructed in a wide variety of
sizes, shapes, and designs. It can be built over a full or partial basement, a crawl space, or a concrete slab foundation (Fig. 2.3).
Before the advantages and disadvantages of the ranch are discussed, here are some general guidelines applicable to all singlestory plans:
■ The single-story plan should provide access from both the front
main entrance and a rear or side entrance into the house without routing people directly through the center of the living room
or kitchen work area.
■ The living room should not be used as a corridor at the expense
of carpeting and furnishings, but should instead provide the privacy for which it was intended. An entry foyer should distribute
traffic so visitors don’t have to step directly into the living room.
This prevents congested cross-traffic and interruptions.
■ The kitchen, laundry, family room, and any busy work center of
the house should be accessible from an outdoor patio or deck, if
one is included with your plan.
FIGURE 2.2

51
52
WHAT TO BUILD
FIGURE 2.3
A ranch home cutaway.
■ The master bedroom suite should be assured of privacy by its
remoteness from the family room, kitchen area, and outdoor living space.
■ If you choose to go with a ranch house, don’t try to match it to a
lot with a substantial forward slope. Ranches look best if they
appear to be hugging the ground; a forward-sloping lot requires
an exposed foundation in the front, which detracts from the low
look of a ranch (Fig. 2.4). Single-story houses are ideally suited
to flat lots or sites that gently slope to the sides or rear, particularly if the plans call for a walkout from a basement or lower living area. This is also a way of economically increasing the
amount of living space since the lower level is an extension of
the foundation.
Advantages
1. Single-stories offer the greatest liveability for all members of the
household regardless of age. Major rooms are located on a single
level (unless a basement has been expanded into living space).
The overwhelming advantage of this house is its suitability to families having senior citizens or young children. There are no second-story stairs to climb up or tumble down.
HOUSE STYLES AND TYPES
FIGURE 2.4
A ranch home on a forward-sloping lot.
2. Single-stories can be made very relaxing and informal through the
use of outdoor space. They offer the most convenience for
indoor/outdoor living, with plenty of possibilities for porches,
patios, terraces, planters, and gardens that can be built adjacent to
and integral with any room.
3. Single-story houses can have spacious basements. You might be
one of those persons who thinks if you’re going to have a cellar, it
might as well be a large one. After all, basements are good for storage, workshops, heating appliances, billiards, ping-pong and other
sports and hobbies, for future expansion of living space, and for
laundry facilities if you can’t have your laundry on the first floor.
4. As a rule, ranch houses are easy to build. They’re close to the
ground. You needn’t resort to double-length ladders and scaffolding to reach much of the structure, as you have to with two-stories
and Cape Cods, for instance.
5. Because there are fewer living levels, heating and cooling systems
don’t have to negotiate additional floors and ceilings once the main
living level is taken care of. The same is true with the plumbing
53
54
WHAT TO BUILD
system. There is much less maneuvering of ducts, pipes, and electrical wiring in a single-story.
6. A single-story plan is the easiest house to keep clean after it’s built.
Not having to climb stairs is a big time-saver. In a ranch you don’t
have to worry about keeping cleaning equipment on more than
one floor.
7. A single-story is easy to expand even if no preparations were made
at the time of original construction. You can simply convert part of
the basement into living area, or you can add on an exterior wing.
Of course, if you know in advance that you want additional space
later (as discussed in chapter 4), you can then make provisions in
the walls where the expansion will be.
8. With a single-story house, you can consider a contemporary-looking sloped ceiling that follows the pitch of the roof so ceiling
joists are not required and a feeling of spaciousness is created.
Insulation and ceiling materials are applied directly to the rafters.
This is a common building practice in the South, but it can also
be used —with today’s energy efficient insulation — in the North
as well.
9. When designed with trussed rafters, a ranch can benefit from the
popular open planning in which living, dining, kitchen, and family alcove sections are designed as part of one interconnected
space. Because structural partitions are not needed except for privacy, areas can be arranged by furniture placements, room
dividers, folding partitions, and even projecting or freestanding
fireplaces.
10. A one-story house is much easier to inspect and maintain due to its
proximity to the ground. The roof pitch is usually very low, so it’s
not difficult to climb onto, walk on, or repair. The outside walls, if
constructed of painted materials, are simple to touch up or repaint,
and it’s easy to perform other routine housekeeping tasks such as
washing windows and cleaning out gutters.
Disadvantages
1. Single-stories have been described as being typically informal due
to the reduced amount of privacy found between their walls. The
HOUSE STYLES AND TYPES
single-floor layout increases the importance of effective interior
zoning—for the careful placement of physical buffers between the
living, working, and sleeping areas. The need for such buffers
(along with an aversion to stair climbing) may be greater in a family that includes very old or very young members who need more
rest than other family members.
2. Some people just don’t feel comfortable sleeping on a first-floor
level, for reasons of privacy and security.
3. Ranch houses cost more to build per square foot than other house
types, because of their high ratio of foundation and roof to living
space.
4. It’s difficult and expensive to build upward on a ranch.
5. Single-level houses usually require relatively wide lots and might
be difficult to locate on smaller size parcels found in many neighborhoods.
6. Heating and cooling costs tend to be higher per square foot in ranches
because all the ceilings and floors are essentially exterior surfaces.
Exterior surfaces allow heat to leak out during the winter and coolness to escape during summer. On multilevel houses, at least some
ceilings and floors are interior surfaces.
7. Although it’s easy enough when you have room to spread out on a
building site, expanding a single-story house can be expensive and
difficult on smaller parcels where the house has already been situated
on the lot according to zoning restrictions. Local restrictions might
prohibit expanding any closer to lot sides and setbacks.
The Cape Cod
This traditional design (Fig. 2.5) derived its nickname from the
place where it was first built. Originally a testament to pure function,
it resembled a simple Monopoly-style square house capped with a
broad low-slung roof all constructed around and over a massive stone
chimney that stood erect through the dead center of the house.
Such a monumental chimney served several purposes. First, since
the entire house had been built up around the chimney, each room had
its own fireplace—either for cooking and/or warmth, and all fireplaces
55
56
WHAT TO BUILD
FIGURE 2.5
A one and one-half-story home.
conveniently shared the same chimney. Second, the chimney also
helped give the house stability against fierce Atlantic gales and shifting seacoast sands.
Most of the original Cape Cods were 38 by 29 feet or smaller. They
had low ceilings, rarely over 7 feet high. That was about the largest
space that could be heated with wood. The entrance was centered at
the front of the house, directly opposite a central stairway that led to
the second floor. The second floor started at the roofline and was often
supplemented with “eye” dormers for additional room, light, and ventilation. Its resulting dormitory-style rooms were popular for storage
and for children’s bedrooms.
On the first floor, the front of the house consisted of two large
rooms, one on each side of the central stairway. A large “Colonial”
kitchen took up the entire rear of the dwelling and was flush against
the massive all-purpose fireplace hearth. The bathroom was out back.
Way out back.
The Cape Cod’s windows were small and shuttered to keep out
windblown sand, hail, and driving January snows. The small panes or
“lites” making up each window were used due to the limitations of the
glass-blowing industry in those days. Large panes were difficult to
make true and clear.
HOUSE STYLES AND TYPES
The entire house usually faced squarely south to take advantage of
every available ray of winter sunshine, plus, cleverly enough, to
enable occupants to tell time: when the sun’s rays came straight
through the front window, hitting a marker on the floor in such a way,
the people inside knew it was high noon.
As decades passed, and long after the original reasons for the Cape
Cod design had ceased to exist, the one and one-half-story house again
found supporters during the Depression days of the 1930s. Homebuilders liked them because Cape Cods were compact, thrifty houses
to construct, especially when the huge fireplaces were left out. Cape
Cods had another resurgence after the World Wars when builders
mass-produced row after row of them. And the houses are still popular today, in larger more luxurious versions.
Here are a few general guidelines for the one and one-half-story
house:
■ It can be built over a full or partial basement, a crawl space, or a
concrete slab foundation.
■ Although the Cape Cod typically still has a front center
entrance, it’s also a good idea to have a rear access as well.
■ As with the ranch, an entrance foyer should distribute traffic so
visitors don’t step directly into the living room from the outside.
■ In a Cape Cod, the master bedroom is often located on the first
floor, with the other bedrooms upstairs. Whether on the first or
second floor, the master bedroom should be assured of privacy.
■ Even if the second story will not be finished off initially, make
provisions for future expansion (Fig. 2.6). Have the ceiling/roof
area insulated instead of the second floor (more on this in chapter 4).
Advantages
1. It’s an economical house to build, with a low cost per square foot of
living area. It requires proportionally less materials and labor to
construct than other types, and because of its relatively small basement foundation and roof, a larger amount of living space can be
had for a smaller financial outlay.
57
58
WHAT TO BUILD
FIGURE 2.6
A one and one-half-story home cutaway.
2. Its two living levels allow distinct zoning for privacy.
3. The Cape Cod is known for its low heating and energy costs, due to
its efficient shape.
4. It can be constructed on a small lot.
5. The completed Cape Cod needs fewer furnishings, less interior
decoration, and takes less time to clean and maintain than other
types.
6. Its low roofline makes it fairly simple to build and maintain, but not
so simple as a ranch.
7. The second story can be left unfinished and initially used for attic
storage. Later, if more living space is needed, the area can then be
employed for practical expansion. This is an economical approach
to the problem of insufficient funds. You can initially run heat and
air-conditioning pipes and ducts, plumbing pipes, and electrical
lines to the second floor and then cap them off there. For air circulation you can install louvered ventilators at each end of the attic
from the start. In short, a design like the Cape Cod offers a great
HOUSE STYLES AND TYPES
“finish it later” potential. This is good for young starters or newlyweds who at first need only a minimum of space but want more
later on, as the family grows. Then, when the children eventually
leave home, the second floor can be converted into an income unit
or merely sealed off and used for storage.
8. Here, one person’s advantage can be another’s disadvantage. Many
people contend that climbing stairs in a Cape Cod or other house
having stairs is good exercise to help keep a person fit.
Disadvantages
1. Upstairs rooms beneath the roof tend to be hot during summer and
cold during winter unless special care is taken when insulating and
installing heating and air-conditioning.
2. When poor planning is followed, the second floor can be cut up
into odd-size rooms, with sloping ceilings and dormer windows—
causing awkward room layouts.
3. There’s the need to provide space for a stairway leading to the second floor. This is space taken away from the first level. And stairs
have to be ascended every time you want to visit the second floor.
4. If there’s a basement beneath the house, the opening used by the
downstairs stairwell takes up more space wreaking havoc with the
compact first floor, where every square foot counts.
The Two-Story House
All things considered, the two-story house is one of the best, most
efficient designs available (Fig. 2.7). It has become increasingly popular for families looking for a spacious yet economical and private
dwelling. A two-story can be built over a full or partial basement, a
crawl space, or a concrete slab foundation (Fig. 2.8). Some general
guidelines to consider are:
■ Once again, through the use of an entry foyer, access should be
provided to all parts of the house from the main entrance. The
entry foyer is usually the best place to start the upstairs stairway, so those entering the house can go straight to the second
floor if they choose.
59
60
WHAT TO BUILD
FIGURE 2.7

FIGURE 2.8
A two-story cutaway.
HOUSE STYLES AND TYPES
■ As in the other house types, the living room should not be a traf-
fic runway.
■ A rear entrance should be provided (or a side entrance), with
direct access to the kitchen, laundry, family room, and all other
working and living areas of the house.
■ The upstairs bedrooms should be planned so you don’t have to
walk through one bedroom to reach another.
Advantages
1. There’s natural zoning between the upstairs and downstairs. The
upstairs serves as an effective buffer between the sleeping areas and
the downstairs living and work spaces.
2. Certain individuals prefer the feelings of privacy, security, and
comfort brought about when the bedrooms are located on a second
story, well above ground level.
3. Building up as opposed to out is cheaper per square foot. A two-level
square house with a given amount of floor space requires only half as
much foundation and roof as it would if constructed as a single-level
dwelling. Building down means a basement. One justification for a
basement is its value as living area. But here the term “living area” is
broadly used to cover basement recreation rooms, workshops, hobby
areas, and similar spaces planned for special activities. If the basement will likely become a depository for junk, then it shouldn’t be
considered as possible living space.
4. Size being equal, it’s cheaper to heat and cool a two-story than a
ranch. Cool air falls, and heat rises. At least one level in a two-story
reaps certain benefits, no matter what the outside temperature is.
5. The two-story is adaptable to small lots. In fact, no other common
type can match it for getting the most house on the least lot. It’s a
good choice on either high-priced land or on a tight little parcel.
And a simple way to gain more space on the second level without
affecting the foundation space requirements is to have the secondstory walls overhang the first-story walls, Garrison style. This also
aesthetically breaks up the highwall appearance you might otherwise find unappealing.
61
62
WHAT TO BUILD
6. A two-story can be successfully expanded without much advance
planning. A family room or wing on the side can be added, but at
substantial cost. Due to its compactness on a lot, there’s usually
plenty of room to build an attached garage. Naturally, if you decide
at the time of original construction that someday you will need
more space, by building expandable features into the house, you’ll
save money in the long run.
7. Physical fitness buffs will swear that a two-story improves the cardiovascular system because occupants are forced to exercise by
climbing up and down stairs.
Disadvantages
1. Having to frequently go up and down stairs makes housekeeping
tougher and puts a strain on parents of young children and on the
elderly.
2. It puts restrictions on a family that likes to spend a lot of time outdoors. Although the downstairs can be designed for easy access to
the backyard, you might find the times needed to trudge upstairs to
retrieve something from a bedroom will amount to a noticeable
inconvenience.
3. Unless the attic of a two-story is properly ventilated, the upstairs
bedrooms will get uncomfortably hot during summer.
4. Without an elaborate network of wood decks and patios, the upstairs
bedrooms are usually shut off from direct access to the outdoors and
are not easy to escape from in case of fire or other emergencies.
5. Although the per-square-foot cost of a two-story is much lower than
that of a single-story, extra footage must be provided in the two-story
to compensate for the space lost to the second-floor stairway. Plus
the upstairs stairway limits the flexibility of the overall design.
6. Long ladders are needed to reach the roof, gutters, and second-story
windows.
The Split Foyer
A split foyer (Fig. 2.9) is essentially a raised single-story house with
the basement or lower level lifted halfway out of the ground and
joined to an entry foyer. The lower level is usually finished off into

part of the house’s living quarters. An identifying characteristic of the
split foyer is that the entry foyer is always located about halfway
between the two living levels. In other words, once you step into a
split foyer you have to go either up or down (usually a half flight of
stairs) to reach a living level (Fig. 2.10). Split foyers have also been
called, rightly and wrongly, mid-levels, raised-levels, and raised
ranches. As with the other house types, there are general points to
keep in mind when designing a split foyer:

64
WHAT TO BUILD
■ Split foyers are meant to be constructed on lots having front-to-
back or back-to-front slopes. It’s silly to place them on dead
level ground. Take a drive through practically any middle-class
suburb. You’ll notice that the worst-looking split foyers—the
“no design” kind, have all been erected on flat lots. Built so,
they appear ungainly and awkward. Instead, they should be
closely fitted onto sloping parcels, so a natural marriage
between the house and land results.
■ The two levels of a split foyer provide distinct zoning to help
separate working and living activities. Further, room functions
can be planned in a variety of ways. On a front-to-back downward sloping lot, the rear entrance is likely to be located in the
upper living area, even if it means the construction of an outside
wood deck or concrete patio with steps to the ground.
■ A split foyer’s entry, like the other entry setups, must direct traf-
fic through a hall or foyer arrangement to upstairs and downstairs rooms without marching visitors through the center of
other rooms along the way. The rear entrance should also permit
easy travel to the kitchen, laundry, and remaining areas.
■ The arrangement of living areas can vary greatly in split foyers.
Some plans have all the bedrooms on one floor, with the working and living space on the other level. Some plans combine
living and sleeping areas on both floors. The garage can be
included in the lower level, or attached to the side of the house
with its own entry. In any layout, the bedrooms—especially the
master bedroom—should be assured privacy from the rest of
the house.
Advantages
1. This design offers easy entry from the outside to either interior
level.
2. The entrance foyer midway between the upper and lower levels
has direct access to at least one bath, thus reducing traffic near the
main living areas.
3. Properly designed, a split foyer can look handsome and large, with
only a short stairway from either level to the outdoors.
HOUSE STYLES AND TYPES
4. The split foyer can provide automatic interior zoning with the
sleeping area on one level and the working and living areas on the
other.
5. Greater window depth is allowed in the lower level, which yields
improved lighting and ventilation. In turn, this helps the area normally referred to as the basement become more desirable for recreation rooms, baths, and bedrooms.
6. The split foyer uses its floor area to the maximum. It has a lower
per-square-foot cost compared to a single-story ranch.
7. The simple floor plan and relatively compact design of this house
results in construction convenience and savings.
8. With proper attention to correct insulation and careful positioning
of heating and cooling appliances, the split foyer is easier to make
energy efficient than a dwelling that has many projections and
corners, or one that is spread out.
9. Most split foyers are suitable for small lots.
10. The minimal foundation and roof areas help reduce construction
costs.
11. When the upper living area faces downhill, you enjoy the full
advantage of a view with height.
12. Again, with this design, a physical fitness buff will proclaim that
exercise on the stairs helps strengthen the heart.
Disadvantages
1. There’s the inconvenience of frequent stair climbing.
2. Even though this dwelling can be energy efficient, because the stairway is more open than that of a two-story, for instance, heat quickly
rises to the upper level. If proper insulation, heating, and cooling
steps are not taken, the lower level tends to be cold during winter.
Special wall insulation below ground level is necessary, and a welldesigned heating/cooling system is a must. Rooms over the garage
can also be chilly if not well insulated. And during summer, without enough insulation, rooms on the upper level will tend to be on
the warm side.
65
66
WHAT TO BUILD
3. The open stairway also reduces the effect of the zoning. Not visually, but because it allows odors and noise to freely move from floor
to floor.
4. The split foyer, due to its structure and design, is not easily expandable at a later date.
5. Because the lower level of a split foyer is usually designed for living areas, there’s not much room to have a basement workshop or
storage facilities.
The Split- or Multilevel
These houses (Figs. 2.11 and 2.12) are essentially split in half vertically with two or more levels so the upper level is only half as high as
the ground level floor. A typical layout for this design has the kitchen,

dining room, and living room on one level (the ground level), with the
bedrooms on another level a half story higher. The ground level may
be over a full basement, or constructed on a crawl space in warmclimate regions, with the upper half story over a garage that’s on a
grade. Here are some general guidelines to keep in mind when planning a multilevel house, or split-level:
■ Split-levels are ideally suited for side-sloping lots on hilly ter-
rain where the bottom level faces and opens toward the downhill side and the upstairs level opens toward the uphill side
(Fig. 2.13). A split-level house placed on a flat lot will look awkward and will not be a very functional dwelling.
■ Arrangements of living areas vary in split-levels. It’s best to have
the living facilities on one of the upper levels with the sleeping
rooms on another for noise breakup and privacy zoning. As with
other types of homes, the bedrooms, especially the master bedroom, should be carefully located for privacy.
68
WHAT TO BUILD
F I G U R E 2 .1 3
A split-level home cutaway.
■ The main entrance may be either on the upper or lower grade, as
determined by the slope of the building site relative to the street.
■ Matching a split-level to a side-sloping lot allows close to a full
height exposure on both sides of the dwelling, making each side
fully accessible to the outdoors.
■ As with other house types, it’s a good idea to have a front and
rear entrance in a split-level, even though these entrances may
be located on different levels. In any event, the living and working centers of the home, including the kitchen and laundry,
should be easily accessible from either entrance.
■ An entry foyer should distribute traffic via a hallway to the
rooms on its own level, and to the stairs leading to other levels.
■ Consider that the basement is usually the best place to put the
heating unit, storage space, and perhaps a workshop if desired.
Advantages
1. It adapts well to lots with side slopes.
2. A split-level has many of the same advantages a split foyer has. It
produces automatic interior zoning. The sleeping area can be on
one level, and the working and living areas on other levels.
HOUSE STYLES AND TYPES
3. A split-level can offer easy entry from the outdoors to any interior
level. On a side-sloping lot you will have at least two main floors
with access straight to the outside.
4. When properly designed, a good split-level will look handsome
and large, with only a short stairway from one level to another.
5. There can be greater window depths in the lower level, which
will gain improved lighting and ventilation for possible expansion of the lower level into a recreation room, bedrooms, or any
other living and working space that you may desire.
6. If the areas beneath the upper level are being used for living space,
or even for a garage, that means at least three-quarters of the floor
area is actively put to good use, thus making the price per square
foot reasonably low.
7. Frequent short bursts of stair climbing are considered a plus by the
health conscious.
8. When the upper level faces downhill, there’s the scenic advantage
of a view with height.
9. With the ability to have access from the outside on at least two levels,
there should be no problem locating a bathroom near each entrance.
Disadvantages
1. Split-level room arrangements can be jumbled and disjointed if
care is not taken during the initial planning stage. You could end
up with a house that requires you to climb steps no matter where
you want to go, or what you want to do.
2. The heating and cooling requirements of split-levels can be very
demanding. The lowest level tends to be cold during winter and
needs special wall insulation for any area below ground. A welldesigned heating/cooling system is a must. Rooms constructed over
a garage tend to be chilly, and the rooms in the upper level are frequently too warm in summer unless proper precautions are taken.
This is largely due to the number of open stairways present, similar
to those in a split foyer.
3. The open stairways reduce the zoning effect by letting odors and
sounds travel freely from one level to another.
69
70
WHAT TO BUILD
4. Because the split-level house has so many different levels, it
can be tough to build. This runs up the cost per square foot, especially if substantial bulldozing of the lot is needed for the
foundation and landscaping, or if retaining walls must be constructed.
5. Another drawback to split-levels is that they’re often difficult to
expand due to limitations of the lot and also because tampering
with the original plan can easily harm the dwelling’s appearance. Too many jogs and angles in the rooflines or exterior walls
make them look cluttered and unplanned, as if put together
piecemeal.
6. The split-level is a poor choice for individuals who prefer large
basements for woodworking shops or want surplus storage space
and footage to eventually turn into a basement recreation room.
7. With the two sections of the side-to-side split-level framed under
two distinct rooflines, the builder must skillfully integrate the two
sections in an artistic manner to avoid the appearance of two separate houses joined together to make a single dwelling.
ALTERNATE HOUSING
In this discussion, alternate housing refers to homes that are constructed differently from typical modern dwellings found in standard
subdivisions across the country. Some dwellings, though, due to local
building materials and climates, can be considered “alternate” in one
location, but not in another (an adobe home in Michigan, for example,
would be neither normal nor serviceable).
Special care is needed when planning alternate housing:
1. Allow plenty of time for the construction. Special materials must
be obtained. Financing and building permits must be secured from
institutions that may not be familiar with “different” methods of
construction.
2. A builder experienced in the kind of construction techniques
needed for you might be difficult to find.
3. You’ll need good, complete budget estimates.
HOUSE STYLES AND TYPES
4. Site selection is usually crucial to the overall success of the completed home. Little things can mean a lot. Water tables, prevailing
winds, orientation, and topography are all very important.
Steel-Framed Construction
Although steel-framed construction is not really a “type” of housing, the use of steel instead of wood framing members varies far
enough from traditional construction methods to be mentioned here.
Indeed, to some individuals, steel-framed dwellings sound just as
“alternative” as the term “underground” housing. To others, they’re a
logical extension of modern architecture. After all, steel framing has
been employed successfully with industrial and commercial buildings
for decades.
Advantages
1. Steel is strong and relatively light for its weight. Steel studs and
other framing components with outer dimensions equal to wood
members are considerably lower in bulk and greater in strength.
Steel members provide increased protection against high winds,
hailstorms, heavy snows, hurricanes, earthquakes, and other
weather extremes. Due to steel’s positive methods of attachment to
the foundation, it’s less likely that the home will separate from the
foundation during an earthquake, hurricane, or other cataclysmic
event.
Because of steel’s high strength-to-weight ratio, and depending
on the design, studs can be placed farther apart instead of using
standard 16-inch wood stud centers (Fig. 2.14). This permits
greater lengths of uninterrupted wall insulation, with fewer thermal breaks in between. Other advantages to steel’s high strengthto-weight ratio include successful home design and construction
on soils that have poor bearing capacities, without using expensive oversize footings.
2. Steel framing allows for more flexible design with larger open
spaces, including longer floor spans and higher walls. Light steelframed walls can be used with dwellings of almost any shape.
3. Uniform manufacturing tolerances maintain a consistent, dimensionally correct steel product. That translates to level floors, flat

WHAT TO BUILD
F I G U R E 2 .1 4
Twenty-four-inch steel stud centers.
HOUSE STYLES AND TYPES
walls, and straight rooflines. Wood members are more likely to
contain natural imperfections such as knots or weak spots.
Cheaper wood studs may arrive at the building site twisted and
can continue to warp even after being nailed in place. Unstable
lumber can add to building costs and create unsightly drywall
stress cracks and nail “pop outs” that are frustrating to repair.
Steel is available in cut-to-length pieces to reduce in-field cutting
and minimize waste.
4. Steel won’t rot, splinter, crack, or readily warp, buckle, or twist.
It’s not as affected by moisture. Other building products, including
paper, gypsum, and wood components, are affected by humidity,
groundwater, and additional sources of moisture.
5. Steel framing members can be ordered to exact lengths and specifications, plus they’re on the market in a wide variety of precut
standard shapes and sizes. Custom shapes are also available. No
high premiums must be paid for extra-long steel framing members,
as must be paid for wood, because steel is, of course, manufactured to length, while not all logs can be sawn into extra-long
boards and beams.
6. Steel resists termites and other wood-destroying insects that can
cause wood roofs to sag, floors to slope, and main beams and posts
to crumble.
7. Steel is not combustible. Although it can be ruined in a hot fire, it
will not burn like wood and does not help fuel a home fire. That can
result in lower fire insurance premiums for some policy holders.
8. Screw-attached metal framing members eliminate squeaks and
“nail pops,” which frequently occur with wood. Screws and bolts
won’t loosen or pull out under stress like nails can. Steel framing
can be manufactured with openings and punch-outs spaced at regular intervals, allowing utility components such as electrical and
plumbing lines to be roughed-in easily, instead of drilling holes
through wooden framing members. Grommets or conduits can
protect the wiring from sharp edges of the punch-outs (Fig. 2.15).
9. Steel framing provides square walls and doors that aren’t affected by
moisture and don’t stick. Such strongly built houses are also much
less likely to settle over the years.
73
74
WHAT TO BUILD
10. Steel framing components, and especially studs, are resilient. That means
they help the walls absorb sound.
When combined with sound-attenuating insulation, they provide quiet bedrooms and other living spaces.
11. Steel framing also helps achieve good
indoor air quality because no pesticides
or other chemical treatments are used,
nor are resin adhesives present, as they
may be with wood.
12. Because steel framing allows for larger
open spans (up to about 60 feet without
interior support walls), a home can be
designed with very few interior loadbearing partitions. Later on, additional
nonbearing walls can be added,
removed, altered, or even relocated
without major disruptions to the home’s
structure.
F I G U R E 2 .1 5
Steel framing with punch-outs.
13. What about lightning? Wouldn’t a
steel-framed home attract direct hits,
like a lightning rod? The steel, if
struck, would actually provide many
conductive paths directly to ground,
where electrical energy would disperse with no greater chance of explosions, fires, or personal injury than
with a dwelling made from wood
framing.
14. What about radio-wave interference? The steel framing shouldn’t
interfere with radio, TV, phone reception, or garage door openers
because the waves can still pass through the spaces between the
studs.
15. What about fastening pictures on walls or other fixtures onto wall
studs? No problem. Simply use metal screws instead of nails.
HOUSE STYLES AND TYPES
Disadvantages
There aren’t many drawbacks to the steel framing members and
panels themselves, but what has been perceived as limiting factors to
construction with steel framing are as follows:
1. Availability of steel framing members at building supply centers is
somewhat limited, but is improving as various contractors are
becoming familiar with using steel in residential dwellings. More
and more lumberyards and commercial building supply warehouses
are adding steel framing product lines as alternatives to wood.
2. Numerous builders are reluctant to switch from wood to steel simply because that would be a departure from long-standing building
techniques they have been using throughout their entire careers.
3. There can be relatively high cost to ship steel framing members from
out-of-state manufacturers, while wood is much more likely to be
“manufactured” locally—and subject to lower transportation costs.
4. A perception exists with many individuals that wood is a warm,
natural, renewable resource and steel is “cold” and manufactured
mainly for commercial use.
5. Some people fear that steel will rust, be an electrical hazard, and
result in dwellings that look like commercial buildings.
STEEL-FRAMED CONSTRUCTIONS BASICS
Entire books are available on steel-framed construction, and manufacturers offer videos, plans, written instructions, courses, and guidebooks on their products. Some basic points and characteristics of steel
construction offered by the various steel kit, component, and package
manufacturers include the following:
■ Steel frame houses appear, inside and out, like wood frame
construction. Once they’re finished, the steel framing is not
apparent.
■ Steel component manufacture is typically cold-formed steel in
shape, size, and function that mirrors dimensional lumber. The
framing components are essentially used in four types of “sections”: floor joist systems, exterior and load-bearing walls, nonload-bearing partition walls, and roof rafter and support systems.
75
76
WHAT TO BUILD
■ Steel components such as studs, joists,

and rafters are stamped into a squared C
shape, called structural-C, C-members,
or simply C. The C configuration is made
of the cross-sectional configuration consisting of a web, flange, and lip. The web
is the part of a C-section that connects
the two flanges (Fig. 2.16). Web stiffeners
are additional pieces attached to the web
to strengthen the web against buckling or
crimping (Fig. 2.17). A flange is the part
that is perpendicular to the web, and the
lip is the part of the C-section that
extends from the flange at the open end.
The lip increases the strength characteristics of the member and
acts as a stiffener to the flange (Fig. 2.16). C-studs, precut or site
cut, are used in structural and nonstructural walls. Channel type
wall studs are designed so facing materials can be screw-attached
quickly (Fig. 2.18). Those made for load-bearing walls are heavier, typically 20- to 16-gauge steel (gauge is a unit of measurement to describe the nominal thickness of steel—the lower the
gauge, the greater the thickness). The studs can be ordered in
sizes up to 8 inches in depth. Deeper studs are used in plumbing
walls and other special situations. Larger C-members such as 2 ×
6s, 8s, and 10s are also made of heavier steel and are used as floor
joists, headers, and in some cases, rafters. When extra strength is
needed, C-members are joined together to form heavier components. Studs are paired or assembled with tracks to create support posts and jack-stud assemblies. Deeper C-members are
joined back-to-back, or flange to flange where heavier beams and
headers are required (see Fig. 2.18).
■ U-shaped channels, or tracks, are used for rim joists and wall
plates, and built-up assemblies of C-members (Fig. 2.19). The
track has a web and flanges, but no lip. When used as wall
plates, vertical studs fit inside the tracks and the flanges are fastened together (Fig. 2.19). Clip-angles are L-shaped short pieces
of metal, usually with a 90-degree bend, used for connections
(Fig. 2.20).

■ The zinc-coated galvanized steel pro-
tects against rust, as does the “red iron”
with its red oxide coating.
■ A homebuilder can purchase the steel
framing components or a complete
house package with windows, doors,
roof, utilities, and more. All the steel
framing members are predrilled, color
coded, and numbered according to the
purchase plans so they bolt together
almost like a life-size erector set. Most
builders use screw guns and self-tapping
screws and sometimes glue to fasten just
about any material to steel framing.
■ A steel-framed house is typically built

over a conventional poured concrete
slab, foundation, or block basement featuring anchor bolts poured in concrete
and sticking up for anchoring (Fig.

■ Manufacturer kits often include flexi-
ble floor plans with clear span interiors
and options such as raised or vaulted
ceilings and decks.
■ Steel framing members are usually

numbered and marked for specific kits
and plans. Framing assemblies bolt
together then can be tilted up onto the
foundation, each bolted to the anchor
plates. For ranch homes, the assemblies
are often light enough to be handled by
several workers without special lifting
equipment. Some designs use individual roof trusses, and others combine the
roof framing members with the wall
framing sections.
HOUSE STYLES AND TYPES
■
To help compensate for thermal
conductivity of steel, builders
include a nonconducting buffer
between the exterior siding and
the steel studs—most generally a
high-density foam board instead of
plywood or fiberboard.
■
It’s possible to erect insulation vertically and hold it in place with zfurring channels. The channels
typically hold insulation blankets,
polystyrene insulation, gypsum
panels, or other rigid insulation
(Fig. 2.22).
79
■ A typical steel framing roof system
is a purloin system which bolts to
the top of the main frame rafters.
They provide excellent strength and
will not sag or weaken over standard lifetimes.
FIGURE 2.21
Anchor bolts.
■
An excellent option when selecting steel framing is the use of
prebuilt panels or assemblies—walls, floors, and other components that have been prefabricated. Panels come in handy especially when there is a repetition of panel types and dimensions.
Panels can be erected quickly on site and can even be put into
place during freezing weather. Because the assemblies are constructed by experienced crews and preinspected, they greatly
reduce on-site wasted materials.
■
Steel can’t do it all. Even when a home is framed with steel,
floor decking and roof sheathing are likely to be plywood or
oriented-strand board. The wood backing, sheathing, and decking are also screwed into place, as are wood window and door
frames. Casings and trim can then be nailed to these wood components in traditional fashion.
■
If you decide to help engineer your own steel framing, consider that most steel suppliers offer in-house engineering at
reduced rates.

STEEL FRAMING INSPECTION POINTERS
■ Screws should be about 3⁄8 to 1⁄ 2 inch
longer than the thickness of the connected materials. At least three exposed
threads should extend through the steel
to ensure a good connection.
■ Insulation should be placed between
all studs in exterior walls, between
structural members and door and window frames on all four sides, in small
spaces between window and door
framing members, behind outlet boxes
in exterior walls, against second-floor
header joists and edge joists, between
the top plate and subfloor of two-story
and split-level dwellings, between ceiling joists of unheated garages or
porches when the rooms above are
used for living areas, between ceiling
joists below unheated attics, below
stairways to unheated attic spaces, in
knee walls of heated attics, on basement walls when those spaces are used
for living areas, around the inside
perimeter of a concrete slab floor in
heated spaces, and other logical spaces
that, due to the building’s design,
would need insulation.

square as they should be, with no uneven surfaces, odd projections, or extra-wide seams or gaps.
Solar Houses
If anything was ever thought to be the answer to the heating fuel
crisis, it has been (and continues to be) the sun. Just the thought of all
that free energy has sent environmentalists scurrying to the bookstores
and libraries for information and plans on how to construct solar
devices. Located just a tad over 90 million miles away from our planet,
HOUSE STYLES AND TYPES
the sun is ultimately the single source of practically all energy we’ve
ever used.
There are two main types of solar heat and energy producing systems: passive and active. Passive systems include design features such
as windows, skylights, and greenhouses coupled with materials that
will absorb or collect and store heat so the heat can be gradually
returned to the home’s living areas. Active systems feature more
advanced methods of storing and distributing the sun’s heat and energy.
In a nutshell, solar systems include about five variations, the first
two being passive, and the latter three, active:
1. Solar Windows. Even in the coldest climates the south side of a
building is warmed by the sun, especially on clear, cloudless days.
Windows positioned on the south side of a home are the collectors
that let the inside surfaces absorb heat. Depending on the heatabsorbing materials (floors, furniture, air, and so on), the heat is
radiated back into the living spaces quickly or slowly.
2. Building Materials/Components Designed for Heat Collection and
Storage. These could be a masonry or stone wall or floor, or a water
container of some type. Something that would hold heat for a long
time and radiate it back into the living spaces at a slow rate, even
after the sun has set.
3. Active Collector with Storage and Distribution. These are what
you’d probably recognize as solar panels positioned on the roof or
side of a building. Heat is drawn from the collector by circulating
air or liquid through the collector and is transferred to a storage
device. The stored heat is then sent throughout the building
through air ducts or piping and radiators.
4. Active Systems that Power Other Heating and Cooling Equipment.
The only difference from the previous system is that the collected heat
is here used to power a secondary heating or cooling system, rather
than directly distributing the collected heat throughout the dwelling.
5. Photovoltaic Cells. These devices convert the sun’s energy to electricity, which in turn can provide heat as well as plain old electric
energy for a variety of other uses.
Almost every home possesses some sort of passive energy features.
Many can be designed into the building plans at surprisingly little
cost. Full-fledged, active solar heating, though, is another story. It can
81
82
WHAT TO BUILD
be quite expensive, especially when the services of a knowledgeable
architect are required.
Naturally, site planning is also a critical consideration when
arranging for solar heating.
Wind-Powered Houses
Rarely are wind-powered homes entirely powered by wind.
Instead, the available wind machines or “windmills” are designed to
supplement energy usages.
Underground Houses
In the mid-nineteenth century, settlers throughout the midwestern
prairies had little selection of building materials. Due to the lack of
forests, little else was available but the sod of the earth. Early sod
homes offered poor protection from the elements. They were dark,
damp, and drafty. By itself, soil is an inadequate insulator. The walls
of a typical sod dwelling possessed an R-factor between 1 and 2, about
the equivalent of a thin piece of plywood.
Today, what we know as underground dwellings also use soil and
sod in their construction. The main difference is that they’re finely
engineered to give their occupants the following benefits:
■ They conserve a site’s surface space. They’re no longer built
upon the surface of the ground. Instead, they’re tucked into the
site, beneath part of the surface.
■ They provide the owner with low energy consumption. At least
several sides, often three, are heavily banked with soil. This
cave-like effect more easily maintains a constant temperature,
summer or winter.
■ They offer excellent privacy and quiet acoustics. Not much
sound can penetrate from outside in, or vice versa.
■ Modern designs provide stable, durable construction, unlike the
old sod homes that easily eroded in the face of prairie storms
and winds.
■ They’re constructed needing low maintenance.
On the other hand, underground homes do not enjoy good reputations by individuals unfamiliar with their construction. People recall
HOUSE STYLES AND TYPES
the cramped underground bomb shelters popular in the 1950s, or
imagine themselves emerging in a bright sunny morning from a dark
cellarlike space, eyes squinting like a mole’s.
Legitimate concerns are for an underground dwelling’s ventilation,
waterproofing, and roof construction. In poorly engineered underground homes, those could pose major problems.
Log Houses
This easily recognized home can be built in practically any size,
style, and floor plan. It’s fairly inexpensive because it uses less framing in its construction than is required of more typically modern
dwellings. They can be either custom-built or of the kit type. A kit log
house is usually the lowest cost option because the manufacturer supplies only what is necessary, with everything cut to size and little
waste. Directions are simple and the construction time quick, although
inclement weather can be a major factor here, as in most construction
schedules.
One limiting factor, however, is where the log home can be built. It
looks out of place in a modern subdivision. Much of its charm comes
from it being located on an agricultural or wooded site.
Pole Frame Houses
Frequently featured in architectural magazines, pole frame homes
feature a rather strong, easy, cost-effective technique of construction,
that of pressure-treated poles embedded in the earth 4 to 6 feet deep
instead of the standard concrete foundation. When firmly anchored in
the subsoil, pole frame homes can be safely constructed in areas
unsuitable for standard foundations, including extremely swampy,
rocky, uneven, or even potentially seismic terrains. This can be so
because the wood pole foundation for a pole frame house also serves
as the major framing members of the dwelling.
Pole frame dwellings also fit nicely into the most modern, exclusive neighborhoods and subdivisions. Their exteriors can be clad with
modern sidings and frequently feature passive solar components
because fewer load-bearing walls are required with pole/beam construction.
Some building codes, however, have not caught up with pole frame
construction, and in certain places it could be difficult to talk savings
and loans and building inspectors into rubber stamping the plans.

WHAT TO BUILD
Also, fewer contractors are familiar with this type of construction, so
accurate cost and time estimates may be more difficult to come by in
your location.
Prefabricated or Manufactured Houses
Prefabricated houses include all factory-built dwellings. For our
purposes, we’ll exclude the motor homes and the mobile homes, and
move on to the three remaining “prefabs”: the shell home, the modular or sectional home, and the panelized home. Each type is available
in a mind-boggling range of plans, cost, and quality.
SHELL HOUSES
These homes consist of little but the exterior shell: walls, rough
flooring, and a roof. The idea is to put up a weather-tight outside shell
of the home, so the inside can be finished off at leisure by the owner,
who frequently, for better or for worse, chooses to do much of the work
him- or herself.
MODULAR OR SECTIONAL HOUSES
These homes are completely built in the factory and are simply
placed or assembled on a waiting foundation. Wiring and plumbing
are already included in the sections or walls. These kinds of homes
can be ready to be occupied within a few days of delivery.
PRECUT AND PANELIZED HOUSES
Precut homes are assembled on the building site out of materials
that have been precisely cut and packaged at the factory. There’s very
little waste, but there’s also a need for strict security at the building site
to prevent theft of parts, of boards or key framing members that might
disappear as they sometimes do from conventional stick-built sites,
where they aren’t missed as much. Panelized homes consist of wall sections built on a factory assembly line. Unlike the walls for modular or
sectional houses, these walls must be finished off at the building site,
frequently by a contractor who must be hired to erect them.
Considerations when comparing prefabricated houses include:
■ Will the finished product be what you expect? Take a look at
several homes that have already been erected, and speak with
their occupants. Prefab manufacturers, at least some of them,
HOUSE STYLES AND TYPES
have wooed customers with all sorts of free giveaway gimmicks,
extras, and other high-pressure sales tactics. Remember that
reputable outfits will offer sound value and reliable customer
follow-up services.
■ Supposedly, the cost of prefabs should be less than the cost of
stick-built houses because the factories use large quantities of
the same materials, with less-expensive labor and less waste.
Depending on the distance from the factory, those savings could
be offset by transportation costs to get the finished product to
your site.
■ Popular designs include the A-frame, ski-chalet, and to a lesser
extent, the geodesic and other multisided dwellings. These
designs are frequently built as second homes, with their
uniquely “different” floor plans affording their owners dramatic
relief from everyday conventional dwellings.
Plenty of literature is available on prefabricated housing. Manufacturers offer brochures, reports, and sales materials, and many annual
publications and monthly magazines are devoted to listing, discussing, and rating the various prefabs currently on the market.
➤➤➤➤➤ POINTS TO PONDER
1. Think about your lifestyle and how you presently live it, or how
you want to change it. Then decide on the amount of space
you’ll need under roof.
2. Review and weigh the advantages and disadvantages of various
home types found in this chapter.
3. Decide on the type and style of house that will best lend itself to
your objectively arrived at space requirements and your subjectively arrived at preferences for appearance and setting.
4. Seek additional advice from real estate professionals who may
urge you to plan more than you need to guarantee increased
value or sales prospects if the home must eventually be sold.
5. All things considered, the two-story house is one of the best,
most efficient designs available. But it does have stairs from one
living space to another.
85
86
WHAT TO BUILD
6. Single-story ranch homes offer the greatest liveability for all
members of a household regardless of age.
7. Cape Cods or story-and-a-half homes are economical to build,
heat, cool, and expand their living space from an unfinished second floor at a later date.
8. Split foyers and split- or multilevel dwellings are best constructed on lots having front-to-back or back-to-front or side-toside slopes.
9. Don’t be afraid to consider alternate construction methods and
materials, including steel framing, solar-power assistance, kit
homes, pole framing, log homes, and prefabricated or manufactured homes. There could even be a manufacturer’s incentive
available for you to be the first in your area to showcase certain
dwelling models.
10. If alternate housing is elected, pay particular attention to choosing a contractor who has had experience with building the type
of home with the type of construction materials and methods
required by your plans.

Traf fic Planning and Zoning
A
fter you’ve reviewed the first two chapters, you should be ready to
begin sketching the general layout and design of your house. As
you do this, give careful consideration to the overall traffic plan and
interior zoning best suited to your own particular situation.
First let’s look at the space in a typical house from another angle.
What about the place you’re living in now? Chances are, you can (or
you wish you could) identify three kinds of space by function. Excluding storage areas, there’s private space, or areas needed for sleeping,
dressing, lovemaking, bathing, and studying. There’s social space, or
areas for being with others, entertaining, relaxing, and recreating. And
there’s transitional space, or places, depending on the circumstances,
where either private or social activities can occur.
To discuss interior zoning in relation to those areas, we must study
traffic that enters and exits the house, traffic that moves within the
house itself, plus room-to-room relationships.
TRAFFIC ENTERING AND EXITING THE HOUSE
Service Access
It might sound snobbish, but there should be a definite entrance to
be used by servicemen, repairmen, and individuals delivering items
87

88
WHAT TO BUILD
they have to carry into the house. Such an entry should be wide
enough, direct, and as short to service areas as possible. The kitchen,
laundry, basement, and utility rooms should be the prime considerations here, since those areas are the places most frequented by servicemen and vendors.
This entrance should be a logical alternative to protect the living
room from unwanted intrusions by casual visitors such as messengers,
salespersons, or unexpected visitors for whom a proper reception has
not been prepared, such as your clergyman or parents-in-law. Ideally,
this access, or a sidewalk that leads to it, should be visible and obvious from the front of your house so people who have never been to
your place can determine which entrance to use by themselves. Otherwise, a small tasteful sign can be strategically placed at a sidewalk that
leads to a side or rear entrance.
The most important idea of a service access is to reduce cross traffic through the living areas of the house whenever possible. Why
invite a meter reader or other service provider to pass through your
dining room while en route to the basement? It’s wise to eliminate as
much of this type of cross traffic as you can.
Guest Access
This entrance is traditionally for friends and guests of the family. It
is the main front door, the entrance that usually faces the front street.
It should be easily accessible from the driveway and the front street,
and from all rooms inside the house so occupants are able to quickly
answer the door when someone arrives.
This entrance should provide guests exterior shelter from the elements while they’re waiting at the door, and should have a place to
remove coats, a closet to hang them up in, and an area in which visitors can adjust to the surroundings (entrance hall, foyer, vestibule,
gallery).
It should provide efficient access to those parts of the house guests
are most likely to frequent. This includes the living room, dining
room, recreation or party room, an office, a patio, the bathrooms—
each family’s pattern of living will determine the needs for guest
accessibility. In addition, this access should give a pleasant impression to visitors, as well as a sampling of the quality and character of
the house.
TRAFFIC PLANNING AND ZONING
Day-to-Day Indoor/Outdoor Movement
Children need a good access to repeatedly go in and out while playing. Because very young children need almost constant supervision, a
back door to their play yard may be a necessity. Excessive running
through the house can be minimized further by locating toilet facilities
near the door most often used by children.
Guests invited for outdoor activities usually enter the house by the
front door then proceed to the location of the activity. This path
should be fairly direct and avoid, if possible, passing through a room.
Because the outdoor living areas are likely to be the setting for picnics, barbecues, and similar events, the exits should be located near
the kitchen. Here again, the availability of bathroom facilities for adult
outdoor activities (in addition to the convenience for children) comes
into play.
Removal of waste materials should involve a minimum of travel
through the inside of the house. Containers for staging garbage and trash
are usually located near the service areas, screened from public view.
If you have a basement planned, consider an outside door for the
convenience of children who are playing downstairs. This lets them run
straight outside without tracking through the rest of the house. And it’s
a great energy and time-saver if your laundry equipment is situated in
the basement, where you can quickly walk outdoors to hang up wet
clothes in nice weather. Also, when you’re working outside in the yard,
you can enter the basement, change clothes, and get cleaned up. It’s nice
to be able to bring large items in through the basement door instead of
carrying them through the house and down the basement stairs. This
means a lot when transporting clothes washers and dryers, freezers,
pool tables, and other large objects. A direct basement access will also
be a time-saver when you store outdoor equipment such as screens,
storm windows, garden tools, and lawn mowers in the cellar.
In addition to the main front entrance, a separate side or rear access
usually serves as the family entrance for grocery shopping, for children
going to and coming from school, for family members taking out the
laundry from a first-floor utility area, plus other informal activities.
General Guidelines for Entries
For safety’s sake, install a peephole or window in your front and
rear doors so you can see who is ringing or knocking.
89
90
WHAT TO BUILD
Again, it’s not a good idea to have a front door that opens directly
into the living room. A main entrance center hall or foyer should both
shield you and your visitors from an inrush of wind, snow, or rain, and
keep your living room privacy intact. Although the main entrance
should lead to the living room area, it shouldn’t encourage people to
pass through the living room on their way to the rest of the house. If so,
it causes interruptions, wear and tear on the carpet, and other inconveniences. A good floor plan will provide access to all main living
areas through hallways or foyers rather than directing traffic from one
main room to another. This also means that you should provide the
ability, even in open-style plans, for direct access to the kitchen and
bedrooms without intruding on living room activities. Thus children
can come and go without interrupting a conversation you are having
with guests in the living room.
The access from the front door to the kitchen should be easy and
direct, as this path is frequently used. There should be a convenient
sheltered entrance to the kitchen from the garage, carport, or driveway,
so groceries can be brought into the house and put away without a lot
of effort and fuss.
You’ll want good guest circulation with the ability to move the
guests from the front door to the coat closet, bathroom, and living
room. A clothes closet is essential near the front and side/rear
entrance, not only for guests but for family members as well.
The remaining components of traffic planning and zoning in a
house deal with internal movement and room-to-room relationships.
INTERNAL MOVEMENT
Here are five points to consider when developing your floor plan:
1. The living, sleeping, and work areas should be separate from
one another. Yet they should be positioned properly in relation
to each other and to additional factors such as orientation to the
street, the sun, and even to scenic views. It’s important to weigh
your feelings toward “bedrooms” versus “work and play noise,”
or “entertaining guests” versus “bothering sleeping children.” In
other words, how much of a buffer zone between the bedrooms
and the rest of the house do you think you’ll need?
TRAFFIC PLANNING AND ZONING
A two-story house contains natural zoning, with the kitchen
and living rooms on the first floor—a full story below the bedrooms. In a single-story house the living and sleeping areas
should generally be located at opposite ends of the house, neatly
connected by the kitchen and utility room.
2. Try to separate quiet rooms from noisy ones by distance. Keep
bedrooms as far away as possible from the living, food preparation, and utility areas. Isolate study rooms from play areas,
hobby rooms, party rooms, and workshops. Adequate soundabsorbing features become particularly important in moderatesize houses with open kitchens, combined living and dining
room areas, and all-purpose family rooms, and also in children’s
play areas and adult workshops.
3. In the interest of silence, though, don’t get carried away. Make
sure no key area is completely isolated (laundry rooms and bathrooms especially), and also see that there’s a safe place for children to play while you’re entertaining in the living room.
4. In houses where stairs are necessary, the head of the stairs
should be centrally located. This not only minimizes the need
for halls, it also frees exterior walls for windows and adds natural lighting and inexpensive ventilation. In two-story houses
the stairway to the basement is usually positioned beneath the
stairs to the second floor. The problem with this setup is one of
arranging your plan so the head of the basement stairs is located
near the service or rear/side door so items can come and go from
the basement in an efficient manner.
5. For ease of internal movement, many people favor an open plan.
Open planning attempts to achieve a feeling of spaciousness; the
interior of a house is made to appear larger than it really is
through the elimination of solid walls between activity centers
and by substituting partial walls, screens, or open room
dividers.
A small dining room will appear larger if no solid wall stands
between it and the living room. The uninterrupted expanse of ceiling
visually increases the appearance of the dining room, and it has the same
effect in the living room. The two rooms “borrow” space from each other.
91
92
WHAT TO BUILD
Similarly, a kitchen will appear larger if it opens to a family room
or dining space. This can be accomplished by using a breakfast bar to
separate the two spaces. The open feeling is not lost even if you opt for
a cabinet over the bar. Space between the bar and cabinet, and the cabinet and the ceiling, as well as the absence of a door between the two
areas will be sufficient to retain the openness.
Of course, there are disadvantages to the open plan: a lack of privacy, conflicting activities can be distracting, and incorrectly grouped
furniture might “float” without unifying walls.
ROOM-TO-ROOM RELATIONSHIPS
Although you might have already read about some of these points
in the first two chapters, many are so important that they bear repeating. A main consideration to keep in mind is that your traffic patterns
should not take people through the middle of several rooms (or even
one room) while en route to another.
The Kitchen
This is considered to be the most important room of a house. Certainly it’s the heart of a house, a place used by the entire family for a
variety of activities. It’s most often placed adjacent to both dining and
living rooms and close to a patio or deck where a barbecue can be
located. If you have a first-floor family room, this too should be within
easy reach of the kitchen, so that the dishes used for snacking are not
far from the sink.
The kitchen should be centrally located to have “control” over the
entire house. Here are other considerations:
■ It should be easily accessible to the front door so guests can be
received, and to the family entrance at the rear or side so a car
can be unloaded and deliveries accepted.
■ From the kitchen you should be able to keep an eye on children
playing either inside or out.
■ The basement stairs should be close by, especially if you have
any food storage down there, or if your laundry is in the cellar.
■ Having a bathroom within a few steps of the kitchen saves a lot
of time.
TRAFFIC PLANNING AND ZONING
■ Consider that an open area from the kitchen to the dining or
family rooms allows for free conversation and visiting while
you’re cleaning up or preparing something to eat. An island or
peninsula, while still “open,” can help separate the kitchen
from a family room to keep curious hands away from hot pots,
pans, and other kitchen hazards.
■ Think twice about a kitchen that steps down into a family room.
It may be harmless to household members who are used to this
arrangement, but it could result in children and guests unfamiliar with such a step taking spills through the years ahead.
■ Ideally a kitchen has no more than two doors, one to the dining
area or front of the house, and one to the service/family entrance
or garage. Within the house there should be alternate ways to
reach those areas without going through the kitchen. If there are
three or more doors in the kitchen they should be located in one
passageway that doesn’t break up the kitchen work traffic.
■ After the kitchen’s location is decided upon, appliances should
be arranged so that distances between the central cooking area
(range), the preparation and cleaning area (the sink), and the
food storage area (the refrigerator and pantry) are no more than
7 feet each (Fig. 3.1).
■ If possible, the kitchen should have at least one, and preferably
two, outside walls in which to place windows. An open kitchen
room arrangement and windows facing the backyard enable parents to
keep an eye on their children during
meal preparation and cleanup. Window screens will enable grease fumes
and cooking odors to be removed.
Windows also serve as pleasant distractions for the busy cook by providing scenic and interesting views
when available.
■ Although the kitchen should have a
convenient central location, watch
out for any traffic patterns that
route individuals from the living

WHAT TO BUILD
room to the bedrooms by passing directly through the kitchen
or dining areas.
The Laundry Area
This feature is usually placed in one of four areas within the house:
1. In or next to the kitchen. This allows much of the required
housework to be done in the same general vicinity, without
wasted motions.
2. In the basement. But this forces you to constantly go up and
down stairs when doing the wash, and if you don’t have a direct
outdoors access from the basement, it makes hanging up clothes
in the yard cumbersome.
3. Near the bedrooms. This makes it handy for changing out of
your soiled clothes and putting away clean garments.
4. In warmer climates where basements aren’t included with many
houses, a popular place to put the laundry is in a mud room
attached to part of the garage or in a breezeway.
No matter where the laundry room is, you’ll need easy access to the
outdoors, you’ll need space for a clothes washer and dryer, soaps and
cleansers, and you’ll need enough room nearby to set up an ironing
board.
The Utility Area
This is where the furnace, air-conditioning unit, water heater, and
possibly a humidifier are set up. From the standpoints of maintenance,
efficiency of operation, and cost of installation, this area should be
somewhat centrally located in a basement, but not out in the middle of
the cellar floor. It should be close to a wall to avoid breaking up a large
portion of otherwise usable space. Although the furnace, water heater,
and related appliances are typically located in the basement, when no
basement is included they’re placed in a mud room, garage, or integrated into their own area right inside the house.
Again, in the basement, the furnace, water heater, heating and airconditioning ducts, humidifier, main electrical box, central vacuum
unit, plumbing pipes, water filters/conditioners, main water supply isolation valve, water fixture isolation valves, sump pump, burglar alarm
TRAFFIC PLANNING AND ZONING
panels, staircases, clothes washer and dryer and laundry sink/tub,
freezer, storage shelves, and related appliances should be positioned out
of the way, or at least where you want them—in case you decide to finish off part of the space later. Yet the equipment needing preventive
maintenance and eventual repairs should be laid out in a manner to
allow easy access. At least one window should be large enough for an
emergency exit—if no outside basement doors are planned.
Bathroom Facilities
Here are some considerations:
■ Avoid having bathrooms visible from other rooms, especially
from the living room or head of the stairs.
■ Be certain that guests can easily get to a bathroom without being
under direct observation from the living room.
■ Position at least one bathroom near the bedrooms.
■ A bathroom should be simple to get to from the rear or side
entrance for children playing or adults entertaining outdoors.
Bedrooms
Bedrooms should be placed together in one part of the house, protected from outside noises as much as possible and also convenient to
bathrooms. This makes parental supervision easier and simplifies the
problem of maintaining a quiet sleeping area.
■ Don’t situate bedrooms one after another in a series requiring
passage through each other.
■ When dressing, people should be able to move between the bed-
rooms and the main bathroom without being seen from the living areas.
■ There should be a buffer zone between the living and sleeping
areas so parents can entertain while children sleep. The placement of bathrooms, hallways, closets, bookshelves, utility
rooms, fireplaces, or other interior masonry walls can serve as
sound barriers between the various quiet rooms and the noiseproducing ones. Avoid “closet” walls that have only a thin plywood or fiberboard backing as the barrier between two rooms.
95
96
WHAT TO BUILD
The Dining Area
The dining area should be adjacent to the food preparation space.
For quick meals many people use a bar that is part of the kitchen work
counter. Others rely on a table in the kitchen, or position a table in the
family room or breakfast room. Still others choose to have a separate
formal dining room next to the kitchen.
The Living Room
The living room should be near the main front entrance. It’s used
for such activities as reading, visiting, and entertaining guests. If your
house won’t have a separate family room, you can use the living room
for watching television and listening to music. In any case, this
room should be at a dead-end location to discourage unnecessary traffic from interrupting conversations and other activities.
Storage Areas
As mentioned earlier, storage is a vital consideration when planning your home. Keep in mind the following points:
■ There should be ample storage in all rooms of a house.
■ Each bedroom should have its own closet(s).
■ It is convenient to have storage space in bathrooms either under
the sink or in a separate closet.
■ The hallway leading to the bedrooms should have a linen closet
for clean sheets, pillowcases, blankets, and other bedding and
bathroom linens.
■ Plan closets near all of the entrance doors: front door, side door,
and rear door. These closets are needed to keep guest and family member coats, hats, boots, umbrellas, and similar personal
clothing and care items.
■ If there’s no formal laundry area, consider a laundry closet near
the kitchen or bedrooms.
■ In the kitchen, a pantry closet for storing canned foods and
appliances is a true plus.
■ A broom closet in the kitchen is needed to store dust mops,
brooms, sweepers, ironing boards, and other unwieldy items.
TRAFFIC PLANNING AND ZONING
GENERAL GUIDELINES
Make sure the size and arrangement of your rooms allows for flexibility of living arrangements. Check that your house plan has enough
windows to provide plenty of natural lighting and cross ventilation,
yet that the windows will not severely limit the wall space for your
furniture and decorations.
✔✔✔✔✔ COMMON MISTAKES CHECKLIST
Before you go to the next chapter, on size planning and future expansion, here’s a checklist of things people often overlook or fall for:
No separate entranceway or foyer to receive visitors.
No window or peephole in the front and rear doors, so the occupants
can’t see who’s knocking or ringing the doorbell.
No roof overhang or similar protection over the front door.
An isolated carport or garage with no sheltered direct access from the
car to the house.
No direct access route from the driveway, carport, or garage to the
kitchen.
No direct route from the back- or side yard to a bathroom so children
can come in and out with a minimum of bother.
Are gas, electric, and water meters planned for the inside of the
house? In the garage or basement? If so, move them outside to eliminate the need for meter readers to clomp through the house every
other month.
A fishbowl picture window in the front of the house exposes you to
every passerby.
Accident-inviting basement doors that open inward toward the cellar
steps.
Walls so cut up by windows and doors that furniture placement is
extremely limited. Plan ahead to accommodate your furnishings. Is
there sufficient wall space? Develop a sense of scale and dimensions
as you evaluate room sizes and window and door locations. The height
of the window sills are important factors. Desks, bureaus, chests,
dressers, and buffets all require wall space. If the window sills are
97
98
WHAT TO BUILD
✔✔✔✔✔ COMMON MISTAKES CHECKLIST (CONTINUED)
high enough, some of the furniture can be placed beneath windows.
Many major furniture pieces are between 30 and 32 inches high.
Windows in children’s rooms that are too low for safety, too high to
see out from, and too small or difficult to escape from in case of a
fire.
A hard-to-open double-hung window over the kitchen sink is a big
pain in the neck. An easy-to-crank casement window is best here,
and a sliding window second best.
A window over the bathtub causes problems. It can result in cold
drafts as well as rotted window sills from condensation.
Bathrooms located directly in the line of sight from living areas, or
directly in view from the top of the stairs so everyone knows when
others are using the bathrooms, makes for embarrassing situations.
Having only one bathroom is especially tough in two-story houses
and split-levels.
No light switches at every room entrance/exit.
No lights or electrical outlets on a porch, patio, or terrace.
No lighting outside to illuminate the approach to the front entrance.
Noisy light switches that go off and on like pistol shots. Silent
switches cost only a little more.
Child-trap closets that can’t be opened from the inside.
Small closets that are hardly large enough for half your wardrobe.
Also watch out for narrow lost doors that keep much of the closet out
of easy reach unless you happen to use a fishing rod. Be careful of
basketball-player shelves too high for a person of normal height, and
clothes poles fastened so low that dresses and trousers can’t hang
without hitting the floor.
Avoid a situation where there is no room for expansion. Sometimes,
due to how the dwelling is placed on the lot, or because of building
or zoning restrictions or construction methods, a house simply cannot be expanded.
Watch out for rooms that are too small to be practical. There’s competition among builders and developers to get the largest number of
TRAFFIC PLANNING AND ZONING
✔✔✔✔✔ COMMON MISTAKES CHECKLIST (CONTINUED)
rooms in a given square footage, at the lowest price. A dining room is
too small if you cannot walk around the table and chairs.
A floor plan that provides poor circulation in and out of the house
and from one room to another.
No interior zoning: the living, working, and sleeping areas are all
jumbled together, each infringing on another’s integrity.
No consideration to the number of floor levels—one, one and onehalf, two, or multilevels—that offer the most advantages and greatest living conveniences to your family.
A house interior that’s dark and drab from a lack of ample window
and glass placements. Strategic windows and glass sliding doors can
go a long way to make your house bright, cheerful, and attractive.
But don’t overdo them; hang on to your privacy as well.
A kitchen that’s situated at one end of the house, not centrally
located.
A poorly designed kitchen. An inefficient work triangle, skimpy
counter space and storage, no place to eat in comfort, and a lack of
outdoor access. If any room of the house deserves the most attention
to detail, it’s the kitchen.
Inadequate storage space throughout the house might not become
apparent for a few years, but when it does, that lack of space will be
most frustrating. Make sure the closets are large enough for storing
household items, linen, and laundry, as well as for personal possessions—seasonal and routine items.

1. The living, sleeping, and work areas should be as separate from
each other as possible. Quiet rooms can be separated from

all-purpose family rooms.
4. There should be enough windows in your floor plan to allow
for plenty of natural lighting and cross ventilation, yet not too
much glass to severely limit furniture and decorative item
placements.
5. Bathrooms should be positioned so their entrance doors are as
private as possible.
6. There should be a direct route from the back- or side yard to a
bathroom so children and adults can come in with a minimum
of bother.

Size Planning
B
efore you begin drawing your final plans and prints, within the
best of your abilities try to determine how large your house should
be and whether you can realistically afford it just yet. If your dream
house is financially out of reach, face the facts. You’ll have to decide
exactly what’s necessary and what can be scaled down, completely
eliminated, or added on at a later date. If you elect future expansion as
the best option, then plan for that expansion long before your new
house is begun.
To start you out on the right track, this chapter covers two important subjects:
1. How to arrive at the correct size house to suit your present and
future needs.
2. How to prepare your house for future expansion.
DECIDING ON THE SIZE OF YOUR HOUSE
The size of a house is generally expressed, as mentioned earlier, in
total square footage of finished floor area. This is the key figure used
today for determining building value.
Often a higher-priced house offers more square footage for the
money, or more value in space per dollar than that offered by an inex-

WHAT TO BUILD
pensive dwelling. Thus cheaper houses are frequently more costly per
square foot. Of course, it also depends on special items and options
built into each home but, all things equal, smaller houses tend to be
more expensive per square foot of living space.
That holds true because smaller houses incur overhead costs comparable to those of larger houses, and in smaller dwellings those same overhead costs must be spread out over a lesser amount of square footage. In
a sense, it’s like buying groceries in bulk. The smaller packages usually
cost more per ounce or per pound than their larger-size counterparts. On
the other hand, smaller homes generally use less energy to heat and cool,
plus there are fewer square feet to maintain and keep clean.
To get a handle on how the costs in a typical house and lot are broken out, those expenses can be separated into three relatively equal
categories (Fig. 4.1): one-third of the costs result from the land and
improvements to that land. Improvements can include a water well,
septic system, utility connections, landscaping, a driveway and sidewalk, and even road construction if needed. Another one-third of the
costs go to the house structure from foundation to roof, including the
house shell and entire framework. The remaining one-third of the
costs come from the vital organs of the house, which include the
plumbing, heating, and electrical systems, and also the kitchen and
bathrooms.
If you study that division of costs, it
becomes evident that when the first and
last categories remain fairly constant in
price, you can considerably add to the size
of the house by increasing the dimensions
of the basic structure at a substantially
reduced cost per square foot of living
space.
Here are some pointers to weigh when
size planning:
F I G U R E 4 .1
A breakdown of house/lot costs.
1. When considering the overall size of
your house, the number of bedrooms
can be used as an acceptable guide. At
least three bedrooms are recommended
even if you have no children or are
planning no children in the future. A
SIZE PLANNING
two-bedroom house is for the most part more difficult to sell
because fewer people are looking for them. Anyway, you can always
turn a spare bedroom into a study, sewing room, or game area.
2. To economize on materials and labor, view the space inside your
house in terms of actual requirements. Determine what each individual room will be used for, and then decide on its size and shape.
You might realize that certain rooms such as walk-in closets are a
waste for you.
3. When designing and planning rooms, consider your present
dwelling. Are the rooms there too small? Or too large? Think about
rooms in other houses you’ve been in. Focus on ones that are close to
what you want. If you can, measure the ideal rooms to leave no doubt
in your mind. And don’t leave out the work area in the kitchen that
will have to accommodate appliances, cabinets, and closet space.
4. The housing requirements of a typical family change about every
five years, as time marches on. You might want to keep that in mind
while laying out the size and shape of your new house. How do you
fit into the following typical household scenario?
■
■
■
■
■
■
Using a young couple just starting out together as the initial family unit, all their living requirements could be contained in a
small dwelling, from a one-bedroom kitchenette/bath apartment
to a two-bedroom house.
Between 5 to 10 years, with the addition of one or two children,
the needs go up to at least two and possibly three bedrooms,
larger living spaces, and more storage.
Between 10 to 15 years, the typical family, if three children are
present by then, needs more sleeping space, a second bath, and
more living and storage area.
From 15 to 25 years, this 10-year span while the children are
maturing is likely to be stable unless the wage-earner’s business
requires a change of locale or an upgrading of living standards.
At 25 through 40 years, during each 5-year period it’s likely that
one child will fly the nest—for marriage or at least for college or
career.
Over 40 years, the family is once again down to two people, and
large amounts of space can become a hindrance rather than a
help.

WHAT TO BUILD
Planning for Future Expansion
For any of a variety of reasons you might not be able or be willing
to start out with the size house you’d like to eventually have. If you
want to avoid jumping from house to house every few years as your
housing needs increase, consider the following:
1. Initially plan a house that can be easily expanded at a later date.
2. Review the house design you want in relation to the ease or complexity of making additions. Allow space and structure adaptability
to add a garage, foyer, family room, bedrooms, second bath, or
whatever it may be that you didn’t initially build into your house.
3. When more space is required of a single-story ranch or two-story
house, the construction of an addition to the rear or side of the
house may be the best (but not the cheapest) answer. In both types
of houses, it’s a good idea to begin with dwellings that are able to
accept additions without having their overall architectural character ruined by those additions. Consider how roof slopes, window
types, exterior finishes, dormers, and similar features will be
affected by the modifications you’re planning. Also pay close attention to property line construction setbacks, so they won’t rule out
your ability to expand in other ways at some future date.
4. If your expansion plans call for knocking out a wall or walls later to
enlarge part of your house, plan for that before the house is completed. Leave plumbing out of the walls that will be removed. Support the above ceiling or floor independently of the affected walls.
Build the framework for the new entrance right into the wall so all
you need to do is knock out the rest of the wall when the time is
right. Electricity is not a problem; light switches and outlets are easily moved.
5. When working with large unfinished places that will eventually be
rendered into living areas, place doors and windows in such a way
that easy-to-install partitions can be erected to turn big, open spaces
into several individual rooms, as desired.
6. Although it might not be the way for you, there’s no doubt that
building up or down is cheaper than building out.
SIZE PLANNING
When Expanding Upwards
If you start out with a Cape Cod, a two-story, or even a ranch house
having unfinished upper levels or attics, there are a number of technical points to be addressed when planning the initial structure.
To permit maximum expansion without resorting to exterior modifications, the roof slope must be steep enough (or a gently sloped roof
raised up enough) to provide adequate head room for new living areas.
For example, on a house having a width of 24 feet or more, make sure
your roof slope—if the roof is not stepped up or raised up substantially—has a minimum of 9 inches of height for every 12 inches of
travel or run toward the peak. Also make certain the floor joists of the
unfinished floor or attic are large enough to carry typical floor loads
(Fig. 4.2).
Whatever your plan, you’ll have to comply with local building
codes that usually require one-half of a room’s ceiling area to have a
minimum floor-to-ceiling height of 71⁄2 feet. Thus, if your attic space
has windows at the gable ends, sufficient head room, and properly
FIGURE 4.2

105
106
WHAT TO BUILD
sized floor joists, the construction of one or more rooms is a relatively
simple and inexpensive project, with no need for exterior remodeling.
Extensions of existing heat, air-conditioning, and return air ducts that
had already been installed to and capped off at the area to be finished
and activation of the already rough plumbing and wiring should result
in a satisfactory expansion of your existing house at a nominal cost.
To attain increased floor area and more wall space for windows,
dormers are recommended. Two types of dormers may be used: the
shed dormer, and the window or gable or “eye” dormer (Fig. 4.3).
The shed dormer is the most practical because it adds a great deal
of floor and wall space and is relatively simple to construct. However,
because it’s not as pleasant to look at as the window dormer, it’s generally built at the rear of the house. A window or “eye” dormer offers
less space, but it’s still a major improvement over nothing. The illumination, ventilation, and increased floor space it brings can transfer an
otherwise little-used space into a cozy bedroom or study. This addition of dormers can often be accomplished without removing the existing structure’s entire roof.
FIGURE 4.3
Shed and gable or eye dormers.
SIZE PLANNING
When Expanding Downwards
If you start out with a house having a basement, and you plan on
eventually using that basement for additional living space, then keep
the following points in mind:
1. Make sure you have enough clear area to allow for basement expansion. You wouldn’t want your water heater, furnace, stairs, and
other items to be laid out so they break up the entire cellar.
2. Use larger-than-normal basement windows for extra light and ventilation, and consider an outside access so you don’t have to walk
through the main part of the house every time you want to go in or
out of the cellar.
3. If you plan to add a bathroom to your basement in the future, be
sure to locate the sewer drain pipes below the cellar floor. If the
sewer pipes enter the basement midway up the wall, you’re in for
extra expense and inconvenience when you have to add a pump
system to push the refuse upwards.
In conclusion, you’ll find that interior expansion is always more
economical than exterior expansion. But exterior expansion provides
extra space without sacrificing attic storage or basement areas.
No matter which direction you plan to expand in—whether it be
up, down, or out—make sure your furnace/air-conditioning units will
have the capacity to handle the extra load.
All in all, a small increase of effort in the initial planning, plus a little additional cost, can make enormous differences in the ease and
expense of expansion at a later date.
➤➤➤➤➤ POINTS TO PONDER
1. As a rule, because smaller houses incur overhead costs comparable to those of larger dwellings, a larger home built on the
same lot with the same quality of construction would likely
cost less per square foot of living space than would that of the
smaller house.
2. When considering the size of your house, the number of bedrooms can be used as a general guideline. At least three bed-

rooms are recommended even if you have no children or are
planning no children in the future, because—unless you’re in
an area heavily populated by retirees—two-bedroom homes are
more difficult to sell because fewer people are looking for them.
Consider your present residence. Are the rooms there too
small? Or too large? Measure ideal rooms to leave no doubt in
your mind as to how large they are.
The housing requirements of a typical family change about
every five years, as time marches on. Consider your family’s
maturation and living needs as you lay out the size and shape
of your new home.
If you’re unable or unwilling to start out with the size home
you’d eventually like to have, consider initially planning and
building a house that can be easily expanded later.
If expansion plans call for knocking out walls later to enlarge part
of the house, plan for that before the home is completed. Leave
plumbing out of the walls that will be removed. Support the
above ceiling or floor independently of the affected walls. Build
the framework for the new entrance right into the wall so all you
need to do is knock out the rest of the wall when the time is right.
When working with large unfinished spaces that will eventually
be rendered into living areas, place doors and windows in such
a way that easy-to-install partitions can be erected to turn those
big, open spaces into several individual rooms, as desired.
Dormers are excellent ways to attain increased floor area and
more wall space for windows.
When expanding upward with a Cape Cod, a two-story, or even
a ranch house having unfinished upper levels or attics, the roof
slope must be steep enough—or a gently sloped roof raised up
enough—to provide adequate head room for new living areas.
And make sure the floor joists of the unfinished floor or attic
are large enough to carry typical floor loads.
When expanding downward into a basement, make sure that the
basement is high enough (9 feet is not too high), that the heating/cooling equipment and stairs are laid out so they won’t break
up the entire cellar, that larger-than-normal basement windows
are used for extra light and ventilation, that an outside access is
considered, and that there’s a logical place to install a bathroom.
CHAPTER

Prints and Drawings
N
ow that the first four chapters have touched upon most of the
major options involved when a house is planned, such as dwelling
styles, types, floor plans, individual rooms, and sundry accessories,
you can see how inefficient it is to just go to a builder and describe
what you want in vague generalities.
WHY YOU SHOULD CREATE THE PLANS
To walk into a skilled contractor’s office and hint merely at what
you think you need, and then let the builder charge ahead and build it
using his or her own discretion, is in a sense like going into a clothing
store and—without even browsing through the racks—telling a salesperson who knows neither your size nor your taste in clothes to please
select an entire suit of clothes, right down to the shoes, that you’ll be
sure to like. The salesperson would be astonished. No one ever leaves
that many decisions up to a total stranger, however knowledgeable
about clothes the salesperson might be. Naturally, the salesperson
would start asking questions, inquiring what type of clothes? Sports,
leisure, business, or social? What size slacks do you take? Made of
which materials, in what colors? For winter or fair-weather use? And
what price range are you looking in?

WHAT TO BUILD
To take the analogy a step further, what about the purchase of an
automobile? A new car is a major expenditure to most of us. You
decide what style, type, and size vehicle is best suited to your needs,
desires, and pocketbook. Few people will stroll into a dealer’s showroom and request a “four-door sedan,” and fewer yet will ask a salesperson to simply suggest something out of the blue. Try it sometime
and see what happens. It’s human nature for a salesperson to try to
convince you to purchase whatever is being pushed at the time by the
dealer. And salespeople are good at that. That’s why they’re in sales.
Builders are a different breed. Builders are accustomed to dealing
with people who walk in cold, having only a foggy idea of what they
want. By far, most builders will play fair with their customers, will try
to help a potential homeowner arrive at a suitable house design. Some,
however, especially during times when plenty of work is available,
become irritated by customers who come expecting counseling services to help plan an entire dwelling from scratch. These builders will
invariably suggest a stock plan—a house they’re thoroughly familiar
with, perhaps one they’ve built within the past few months.
Other builders, when faced with an undecided client, will ask
dozens of questions such as “How large do you want the bedrooms?”
and “What size garage?” Then they try to piece together an appropriate
plan from your answers.
Somewhere along the line each builder is going to have to know
how much material to order. How else can he bid the job? To know
that, he’s going to need a set of plans, a set of blueprints and drawings
to use as a guide. And just as a cook needs to follow recipes in the
kitchen, so does a builder need prints and drawings to follow in the
field.
If you’re still not convinced that you should participate fully in the
creation of the prints and drawings by making many of the optional
construction decisions yourself, then consider that the builder wants
you to be pleased with the finished product, but rarely does that concern go too far past the technical level. Do you really think it will register on a contractor if you say “Gee, you should have made the family
room 2 feet longer so we could fit our overstuffed sofa in front of the
fireplace”? What else can he say but “I’m sorry. It was on the plans you
approved.” To mention that the basement has heaved up and it’s full of
water—now that will register. Builders can handle complaints center-
PRINTS AND DRAWINGS
ing on the actual construction—the carrying out of the original agreed
upon plans. But if you chastise a contractor after he erects the house
that the garage should have been located on the other side of the
dwelling to act as a shield against prevailing winter winds—your
efforts will likely fall on deaf ears.
FINAL SET OF PLANS
No matter where you get them, your final set of prints and drawings
should in some way address the following:
Floor Plans
One blueprint for each floor. These are working drawings showing
overall dimensions, room and hallway sizes, location and sizes of
doors and windows, location of interior partitions and wall thicknesses, location of electrical switches, plugs, and appliances, plumbing fixtures, water supply, drains, and other information needed to
complete the house (Fig. 5.1).
Lot Plan
The lot plan shows the original contour of the land, the proposed
finished contours, original trees and the ones which will be left standing, the location of a water well and septic tank if applicable, the driveway, electrical service, and the placement or orientation of the
house on the building site (Fig. 5.2).
Foundation Plan
The foundation plan shows the height of the sill (where the house
frame rests on the foundation or top of the basement) above grade, the
chimney location, the extent of excavation and grading required, plus
the location of water and sewer hookups and easements (Fig. 5.3).
Elevation Drawing
The elevation drawing depicts the lines of the house from its four
or more sides. You might need a front, rear, and two side views,
depending on the complexity of the house. It will show where windows and doors go, and their respective sizes. Exterior material types
can also be indicated here (Fig. 5.4).

If the interior has any unusual or distinctive features, you might
want artist’s renditions to help you visualize what the interior will
look like. An example would be an elaborate bathroom or special
kitchen cabinet setups (Fig. 5.5).
Perspective Sketch
The sketch shows what the completed house will look like from the
outside, including landscaping if desired.
Finally, you should request at least four and possibly five complete
sets of plans—one for the builder, one for the lending institution, one
for the local building department, one for yourself, and, just in case, an
extra set for your records.

PREPARING YOUR PLANS
There are a number of ways you can complete the plans you’ll need
before going to contractors and soliciting bids.
1. Have an architect do them for you, with your help.
2. Purchase a set of stock plans through a mail-order company.
3. Prepare them yourself with help from books, magazines, and
friends.
4. Use packaged planning kits.
5. Employ a personal computer and special home designing
software.
Architects
The truly great houses in the world have practically all been
designed by architects. Indeed, architects are wonderful at custom
engineering houses that require complex construction techniques or
unique materials. If you’ve got a building site in the middle of a
swamp, or on a ledge of solid rock, an architect will be able to figure
out how to build on it. And due to the nature of their business, they
stay abreast of the latest energy-saving techniques and other technical
innovations. Whether an architect is right for you depends on the complexity of your design and building site, and your bank account. Like
any professionals, architects are well compensated for their efforts.
Stock Plans
If you’d prefer not to draw your own initial plans, and hiring an
architect is out of the question, consider stock prints and drawings
that have already been prepared by professionals and are available
through mail-order companies. Even if you can’t find exactly what you
want, plans can always be modified to some extent by your
builder/architect. Remember that care must be taken, because major
changes can cause structural problems—especially when altering a
foundation to match a lot or when changing load-bearing walls.
One advantage to using stock plans is simple economy. They’re
inexpensive themselves, and their dimensioning of rooms and spaces
117

WHAT TO BUILD
for suitable structural members are made with a minimum amount of
waste by using standard lumber. This is because stock plans are prepared by experienced home design experts who have accumulated a
broad range of planning ideas over a considerable length of time. Some
are licensed practicing architects.
Do-It-Yourself
To help you commit your ideas to paper, there’s a wonderful invention available at nominal cost: graph paper. Graph paper is an ideal
medium for expressing room sizes and relationships of a floor plan. A
good scale to work with is 1⁄4-inch equals 1 linear foot. You’ll also need
a roll-up steel or plastic tape measure at least 25 feet long, plus some
home design books and magazines that will give you average dimensions and proportions of various features in houses such as hallway
widths, door heights, and wall thicknesses. Many of these dimensions
can be found within this book.
Once you finish your plans the best way you know how, the builder
can use his knowledge of construction materials to point out where
adding a few feet here, or taking away a few inches there, can result in
substantial savings. If plywood sheets come in 4- by 8-foot sheets (and
they do), it would be silly to spec out a room that would require coverage by ten sheets of 41⁄2- by 8-foot sheets. That would result in sizeable waste.
Builder/architects can take your estimates and customize them—
still keeping your plan’s original integrity—to dimensions that lend
themselves to standard building material sizes in order to reduce
waste and give you more for your money. Builder/architects have a
realistic feel for how to stretch materials to the maximum. They’ll be
able to take your rough drawings and show you where you can pick
up efficiencies, and where you could use substantially less materials—perhaps by merely altering a particular dimension in some
minor way.
Packaged Planning Kits
If you’d like to explore a simpler method of creating your own
house plans, packaged planning kits are available from a variety of
companies and publishers. They consist of scaled grid sheets or boards
and appropriately sized furniture; construction parts such as win-
PRINTS AND DRAWINGS
dows, doors, and walls; and even landscaping trees and shrubs.
They’re simple to use, and they can help plan how much furniture
your house will need and where it should go.
The kits come with instructions and most are designed with a 1⁄4inch scale. They can help you reduce the cost of professional drawings; the designer can do the drawings a lot faster if he or she just
copies from your layout.
Most kits are manufactured in two-dimensional style, but some
offer three-dimensional planning—a great help if you have a difficult
time conceptualizing and visualizing whether a room design you are
planning would fit the space allotted. The 3-D kits tend to be twice the
scale of the others to give you a better grasp of the cardboard, plastic,
or foam furniture replicas. These life-like objects include plumbing
fixtures, televisions, stereos, sofas, toilets, even pianos. Some kits use
decals, and plastic or cardboard printed in 3-D style. Other kits supply
foam furniture that you can paint or even upholster to try out color
schemes.
Computer-Assisted Plans
For the ultimate in home design at your fingertips, turn to the personal computer. Architects have been using CAD (computer-assisted
design) graphics and engineering packages for years, but now that the
personal computer has become so affordable and easy to use, it’s certainly an interesting option.
Software is available to help you draw your own designs on a monitor or computer screen. And computer screens are great to work with
because they’re so easy to change, with no harm done if you make a
mistake. With some programs you can look at the drawings in 3-D; you
can rotate them right on the screen to see all angles of a room or entire
floor plan. You can save the drawings on disks and print them out on
a printer whenever you need a copy.
The details on these programs are incredible—down to the patterns
on wallpaper. You can ask for overhead and side views, and you can
even fast-forward a newly planted landscaping scheme to see how it
will look years in the future, when fully grown.
These accurate designs can help reduce the effort and cost of having professionals complete your set of plans.

WHAT TO BUILD
BEFORE APPROACHING THE BUILDER
It’s important that your plans are as detailed as possible before you
meet with contractors; otherwise, you’ll be at a disadvantage in regard
to the bids. In order to protect themselves against work that is not
clearly spelled out, they might pad their bids. At the same time, some
could attempt to make you do without items you are taking for
granted, which are not initially specified.
➤➤➤➤➤ POINTS TO PONDER
1. Unless you have absolutely no opinion on what you’re going to
be living in, at the very least, provide some active input into the
planning of your new home.
2. An ideal set of home plans includes floor plans, a lot plan, a
foundation plan, an elevation drawing, an interior sketch, and
a perspective or outside sketch, with landscaping if desired.
3. There are different ways to complete new house plans. You could
use an architect; purchase a set of stock plans through a mail
order company; prepare them yourself with help from books,
magazines, the Internet, and friends; use packaged planning kits;
or employ a personal computer with home-designing software.
4. Architects are great but expensive.
5. Stock plans are good—and they can be modified to some extent
by your builder/architect. They’re usually quite economical
because they’re prepared by experienced home design experts
who have accumulated a broad range of planning ideas over a
considerable length of time.
6. Do-it-yourself plans are entirely possible. Don’t be afraid to try.
A good builder can take your drawings and have a complete set
of technically correct plans made, adding efficiencies when
drawing from his knowledge of available construction material
dimensions.
7. Two-dimensional and 3-D packaged planning kits are available
for a simple way of creating house plans. They can help you
reduce the cost of professional drawings because the designer
can do the drawing a lot faster if he or she just copies from your
layout.
PRINTS AND DRAWINGS
8. If you’re computer literate, some excellent software programs
are available to walk you through numerous home design scenarios and can print out a variety of overhead, side, and even
landscaped views.
9. It’s important that your plans are as detailed as possible before
meeting with the contractors. Do your homework in advance.
Make all of the decisions you can beforehand.
10. Remain open, however, to good suggestions offered by
builders. Don’t be reluctant to modify your plans in reaction to
new information that would better suit your purpose.

How to Build It
I
f you never even lift a hammer throughout the entire construction
process, it still pays to know how a house can and should be put
together. How else could you make educated decisions concerning the
building specifications that are so crucial to a dwelling’s quality of
construction and overall durability, safety, and comfort? Often the
difference between mediocre and excellent construction involves a
ridiculously small materials cost. Knowing construction methods and
materials will also assist in your dealings with whichever contractor
you choose.
While it’s not necessary to be able to recite good specifications from
memory, it’s important that you have a sense of how the contractor
should go about fulfilling his obligations. Chapters 6 through 27 cover
what should happen from foundation to rooftop and point out essential
decisions that need to be made and should be made with your input.

Footers and Foundations
N
o house will be solid enough to reach its full life expectancy unless
it’s carefully constructed on adequate footers and foundations.
FOOTERS
A footer, as the name implies, is that lowest part of a house upon
which the rest of the dwelling is placed. And like anyone’s foot, if it’s
not firmly planted on the ground, proper posture or position of the rest
of the body (or in this case, the house) becomes difficult if not impossible to maintain. A house footer serves to firmly situate the building
onto and into the ground. And because it plays such a basic and critical role, it’s important to make sure that the footer is done correctly.
Footers are largely inaccessible once covered and landscaped over,
and if ineptly constructed, major problems will result in huge
expenses and inconveniences to homeowners.
Few people realize exactly what a house sits on, and how the house
is joined to the earth. There are right and wrong ways to construct a
footer; the main idea is to evenly spread or distribute the weight of the
house over a large enough area of soil so that settling or moving will
never occur. The chief enemies are gravity and time. Downward pressure that’s not evenly supported from below will ultimately result in
125

126
HOW TO BUILD IT
cracked floors, foundations, and telltale symptoms such as doors that
will not close, cracks in plaster, and worst of all, an obvious tilting of
the house.
Construction Guidelines
Consider the following when planning your footer:
1. It must be built on virgin soil if conventional building practices
are to be followed. Sure, some houses are constructed on swampland—but they require extra engineering, expense, and effort. The
standard-type house should rest upon solid ground. This means
shy away from a building lot that has been filled in and graded to
bring its surface up to a respectable level.
Consider arranging for a soil test hole to be dug where the basement will be. It will identify soil types and may detect the presence
of water or boulders below grade. Digging the test hole will also help
get more accurate prices on excavation, foundation, and drainage
work, plus it will prevent major surprises and possible delays.
2. If you realize the land consists of recently filled loose soil, and you
still desire to build on it, several options exist. You can have the
soil compacted through mechanical means. Contractors can use a
heavy-duty tamper that hammers the soil down, plus huge rollers
that pass back and forth over the surface, compacting as it moves.
Together these machines press the soil until the proper “load
level” or ability to support weight is reached that’s similar to that
of virgin earth (undisturbed ground).
If the depth of uncompacted soil is too great to be efficiently
compacted, and a deep cellar might lend itself to the house’s structure, you could excavate and remove the disturbed ground until
you hit virgin soil, then build from there.
A last and most radical alternative could apply if virgin ground
is entirely too far below grade to fix by either compacting or excavating. Here the solution is to architecturally design a one-of-akind footer of the floating nature to adequately support the house
you plan. In most cases, though, the expense is too great to bother
with. It is better to find a more suitable site.
Either of the first two options will also cost more than an ideal
lot, but they’re necessary if you are to prevent the house from
FOOTERS AND FOUNDATIONS
127
shifting and being subject to the difficult-to-correct ailments
described earlier. Unless concrete is poured onto undisturbed or
properly compacted soil, its weight, when coupled with that of
the foundation and the rest of the house, will slowly press down
the loose soil below. This will result in cracks, heaving, and tilting
which naturally will disturb the framework of the rest of the
house. Suddenly the windows won’t go up as easily, the doors
will no longer fit their frames, plaster walls will crack—all indicating that stressful pressures are at work that will probably brand
the house as shoddily constructed.
3. The frost line must be taken into account. The earth is an insulator, and in northern sections some of the top ground freezes and
offers protection to the unfrozen soil below. The frost line is an
imaginary undulating plane located at some depth below the surface, or the average depth of ground that can be expected to freeze
during winter, year after year. In the northern parts of the United
States for instance, it ranges from about 2 to 5 feet below typical
ground level. If a footer is not placed
below that frost line, the alternate
expansion and contraction of the earth
above the frost line might cause the
footer to move—to heave upward or
list downward, causing cracks to
occur in rigid concrete footers and
foundations, with their accompanying
ill effects. In general, national building
codes recommend that footers should
be located at least 12 inches below the
frost line (Fig. 6.1).
4. The type and condition of the soil
must also be taken into consideration.
For example, it’s an unwise practice to
build on organic type soils such as
peat: they haven’t the proper loadbearing strength to support the weight of a
house. Groundwater content likewise
influences the ability of the soil to
support weight and greatly affects the

HOW TO BUILD IT
installation of proper drainage to prevent water from seeping into
lower levels. Be careful not to build over a spot where a large tree
root system still exists: the roots will slowly disintegrate, leaving
voids that will undermine the footer and lower-level floor. Major
tree roots should be removed and the holes left by them filled in
and compacted.
5. Naturally, the contour of the building site and the distribution of
the house’s weight can have a major effect on the footer’s construction demands. A two-story dwelling with one floor directly
above another, even if it weighs the same as a multilevel that’s
spaced out over more area of ground, will distribute its weight in
a different manner—thus the need for a different footer than that
of the multilevel’s. In many cases, footers must be custom
designed for lots having substantial slopes. “Steps” are commonly
included to compensate for grade differences (Fig. 6.2). When
preparing for a block foundation, as a general rule, the depth of
FIGURE 6.2

each step should be in a multiple of 8 inches, which happens to be
the height of the standard concrete building block. That helps
build uniformity into the foundation so you won’t end up having
to add a half-course of block somewhere along the top of the foundation, with the accompanying waste and bother.
6. When a full basement is specified for a house, there should be an
excavation of proper width, length, and depth to accommodate the
foundation walls, piers and support columns, pilasters, entryways, fireplaces, chimney stack, basement floors, garages, patios
and porches, and an adequate drainage systems (Fig. 6.3).
7. Pour separate footers wherever steel-support columns will be
located (concrete columns that support the house’s main steel
beam or beams). This helps relieve downward pressure and will
help prevent the basement floor from cracking. A footer for a pier,
post, or column should be square and should have a pin or fasteners to securely anchor the post bottom. Check local building codes.
130
HOW TO BUILD IT
8. A bed of gravel must be laid under and
around the planned footer and foundation wall, no matter which type of
footer is used (Fig. 6.4).
9. Footers for single-story and one and
one-half-story houses should be at least
8 inches thick and 16 inches wide; for a
two-story dwelling, 12 inches thick and
24 inches wide. Larger footers are
needed for homes constructed on unstable earth or on filled land. In general, a
rule of thumb is that footers be at least
FIGURE 6.4
as deep as the foundation wall is thick,
and twice as wide (Fig. 6.5). With conA footer with gravel and rebar.
crete slab construction, contractors
often simply increase the thickness of the slab under the load-bearing
walls instead of pouring separate footers. The width of footer and
foundation walls should be increased when brick or stone veneer is
used on the exterior of the house. A single-story-home footer may go
from 8 by 16 to 12 by 24 inches with foundation walls 12 inches thick.
The contractor’s engineer and local building code should determine
the proper footer size and foundation
wall thicknesses. In all cases the footer
must meet the local building code
minimum specifications. When the
footer excavation takes place, make
sure it’s not dug too deep. You don’t
want the excavators to backfill fresh
soil before the footer and basement
floor are poured. It’s critical to pour
both onto virgin soil.
FIGURE 6.5
Footer design.
10. As mentioned before, if the earth on a
potential building site is unstable, you
would do best to avoid such a lot in
favor of another with virgin soil. If you
decide to build on a filled lot anyway,
have a structural engineer design the
FOOTERS AND FOUNDATIONS
131
footer. He or she may have to go extra lengths to compensate for
soil weaknesses.
11. The concrete used in footers should have a strength of at least
4,000 or more pounds per square inch. The footer strength must
also meet local building code requirements.
12. Reinforce a footer for extra strength. This applies to all footers,
including those for fireplaces and support columns or piers. In
normal situations, embed at least three steel reinforcement rebars
lengthwise throughout the footer (Fig. 6.6). Typically, steel rebar
should be at least 5⁄8-inch thick and elevated from the ground during and after the concrete pouring through the use of “foundation
chairs” concreted right in, about every 6 feet. Thicker steel rebar
may be required depending on the application, and on local building codes. The bars are usually situated so they will be covered by
a minimum of 3 inches of concrete at all points. Overlaps should
occur wherever the bars meet, and those overlaps should be wired
together. The use of 20-foot or longer rebar rods will minimize the
FIGURE 6.6
Footer reinforcement—rebar on chairs.
132
HOW TO BUILD IT
number of overlaps necessary. The overlaps should occur in
straight runs, never at corners, and parallel runs of rebar should
have staggered overlaps so two or three overlaps will not occur at
the same point in a run. The rods should be bent and continued in
single pieces around corners. The local building code may specify
rod and overlap dimensions. Vertical support rods for the foundation walls should also be placed in the footer before the footer is
poured, so those rods are securely anchored.
13. If you’re going to have solid poured concrete foundation walls,
consider placing a 2-inch keyway in the footer. Once the footer is
poured and setting up, a 2-inch keyway can be formed into its top
to allow the solid poured concrete wall to have a solid water resistant connection with the footer.
14. Allow concrete used for footers two days to set to gain most of its
strength before anything is done on top of it. Make sure footers are
level, with no visible cracks.
15. Depending on the type of foundation your house requires, there are
a number of items that might have to be prepared for while the
footer is being installed. These include drains and sewers, plus
water, gas, electric, and phone lines. If the necessary holes or
trenches are dug for these items while the backhoe/shovel is present for excavating the footer and basement, they can be completed
at less cost. The backhoe/shovel won’t have to come back a second
time, nor will the contractor need costly labor to dig them by hand.
16. Special attention to the sewer or septic lines prior to pouring the
footer will prevent basic sewage problems. If your house will be
connected to a street sewer, this connection should be made at the
excavation/footer/foundation stages of construction. The sewer
usually runs under a wall footer and basement floor to the main
stack location. If a septic system will be used, the same sanitary
sewer pipe installation must be made from the septic tank location
to the stack. In any case, you don’t want to end up with your house
sewer discharge line below the line it needs to be hooked up to.
17. Last, make sure the contractor grades and stones the driveway
while the footer is going in—before the construction of the foundation and rest of the house begins. An early graded and stoned
drive where the finished driveway will go is convenient for
FOOTERS AND FOUNDATIONS
receiving material deliveries and for simply getting onto and off
the site in bad weather. It will also encourage the heavy cement
trucks needed for the footer, foundation, and basement floor to
pack down the gravel and earth driveway long before the finished
driveway will be poured or asphalted. All of the heavy equipment
and delivery traffic will result in a stronger driveway base.
FOUNDATIONS
To put it in simple terms, the foundation of a house is what sets
directly above the concrete footer and below the wood-frame living
levels. Another way of describing most foundations is to call them
basement walls. In houses without basements, a slab foundation also
incorporates the dwelling’s footer in one continuous piece of concrete.
The foundation must be strong enough, whatever its construction,
to support the house sills (heavy horizontal timbers or planks attached
to the upper part of the foundation to serve as a starting point for the
house walls) and other related members of the house structure, as
required.
From a structural standpoint, the foundation performs several key
functions:
■ It supports the weight of the house and any other vertical loads,
such as snow.
■ It stabilizes the house against horizontal forces such as wind.
■ It acts as a retaining wall against the earth fill around the house.
■ In some cases, a basement might be needed to act as a barrier to
moisture or heat loss.
No matter which foundation type you must have, or elect to have,
some general points apply. All foundations, whether slab type, crawl
spaces, basements, or any others, should extend above the final grade
enough so that wood members of the house are some distance above
the soil. That distance might be regulated by local building codes.
However, keep in mind as the specs of your foundation are laid out
that if local building codes are being used as a guide, they’ll help, but
they could still fall short of what many people would consider optimum construction. Local specs lay down minimum rules for safety
133
134
HOW TO BUILD IT
and health, but that’s about all. In other words, you might want to go a
few steps beyond what they recommend. In this case, it’s better to
position the top of your foundation slightly higher, away from the
ground level, for added protection against moisture and insects.
When excavating is necessary—and that’s likely for any of the foundation types you will consider—have the valuable topsoil scraped off
and saved. It should be pushed into a pile and kept out of the way until
the house is completed and the landscaping is roughly finished, so
you can spread the topsoil around to provide a fertile base in which to
plant grass seed or to lay sod. Don’t let the topsoil become “lost”
amidst the rest of the soil that’s excavated and used to fill in around
the foundation.
Slab Foundations
The slab foundation, as mentioned earlier, generally involves a
combination of footer and foundation into a single slab of concrete
(Fig. 6.7). They’re popular wherever basements are impractical or
impossible to have, in certain parts of the Southwest and South for
instance, or in areas with high groundwater levels.
The “floating” slab is unique in that the finished concrete floor,
foundation walls, and footers are reinforced together with steel mesh
and metal rods and poured as one integral mass over a bed of gravel
(Fig. 6.8). The entire slab thus floats on top of the ground while functioning as the floor of the house. However, the depth of the concrete
should not be equal throughout its overall area: the slab must be
thicker beneath support walls if the footer is considered part of the
slab.
In cases where the terrain is not relatively flat, a footer must be
poured separately from the slab and terraced or stepped down. Then a
FIGURE 6.7

FOOTERS AND FOUNDATIONS
135
FIGURE 6.8

foundation, usually of concrete block, is constructed to a certain level
height so a concrete slab floor can be poured. A slab foundation can be
very trouble free and economical when built in adherence to the following construction points:
1. First, the site must be properly graded and compacted, and the
footing trenches dug.
2. If the slab will be placed directly on soil, make sure the area is free
of biodegradable tree roots and debris.
3. Granular fill makes a better base than soil. Bank or river gravel,
crushed stone, or slag can all be used, in sizes from 3⁄8- to 1-inch
thick. A 6- to 12-inch-thick granular bed of fill will suffice.
4. At this stage all of the following underground utilities should be
installed: plumbing, drains, sewers, heating service lines and
ducts, radiant pipes, electrical work, and any other public or private utilities. Steel sleeves with foam insulation inside should be
placed over all water and sewer pipes where those pipes protrude
136
HOW TO BUILD IT
from a concrete slab, allowing the pipes to “give” if a slight adjustment is needed when the connection is made. Remember that if
your house will have a slab foundation, you’re going to end up
with one continuous slab of concrete. If anything is done wrong
and not corrected after the concrete is poured and before it dries,
just think of the trouble and expense you’d have to go through to
simply get at the problem, let alone to fix it. Take precautions to
see that the utilities are all accounted for and installed in a safe
and correct fashion.
When run beneath a concrete floor, water lines should be laid
in trenches deep enough to prevent freezing (below the frost line).
Pressure-check the plumbing for leaks before the concrete is
poured. The water should be turned on with all faucets and shutoffs closed to make sure there are no leaking seams, cracks, or
holes through which concrete could seep, to solidify and plug
water or drainage lines.
Make sure copper pipe is wrapped in a rubber or plastic tape
wherever it will come in contact with concrete. An undesirable
chemical reaction occurs when bare copper meets concrete. It’s
another simple precaution that can save a lot of time, expense, and
inconvenience at some later date.
5. The subgrade for the slab should be dressed up or smoothed out in
preparation for the concrete pour. Whether the subgrade is gravel or
slag, it must be thoroughly compacted. It should end up higher than
the surrounding grade so water will drain away from the house and
so the top of the slab is comfortably higher than ground level.
6. At this stage, a vapor barrier is placed over the sub-base to stop the
movement of liquid water and water vapor into the slab. Among
materials used as successful vapor barriers are heavy-duty sheets
of roofing material, polyethylene plastic, and construction paper.
They act as both an insulation and moisture control, holding
dampness in the ground rather than permitting it to penetrate
cracks that could form in the slab foundation.
7. The slab should now be reinforced with steel rods. Although the
steel reinforcement will not assure the prevention of cracks, it
might reduce the magnitude of cracks that would otherwise occur.
For best results, the steel is placed horizontally through the mid-
FOOTERS AND FOUNDATIONS
dle of the slab and held in position until the concrete dries. A common practice of placing the reinforcement rods on the sub-base,
then pulling it up to the center of the slab with a rake or hook
should not be permitted. It’s virtually impossible to accurately
control the location of the rods or wire fabric with this method.
Instead, steel bridging or “chairs” can be anchored into the subbase. The chairs will stick up to about the midpoint of the slab and
will correctly hold the reinforcement when the concrete is poured.
Naturally, the chairs will be concreted right into the slab, along
with the reinforcing steel.
8. In addition to steel rods, welded wire fabric or mesh is required
for slab foundations. Again, this material makes the concrete less
likely to break loose from itself. Wire joints should be overlapped
and wired together according to your building code, unless the
entire job can be done with a single piece.
9. In an application where a foundation is required to hold up a concrete slab (with the interior filled with bank gravel to support the
slab) then the top block—if it’s a concrete block foundation—or the
top ledge—if it’s a poured foundation—should be a header or shoe
block form in which a portion of the block/concrete has been cut/left
out to provide a base for the concrete slab to be fastened to or supported on (Fig. 6.9). Vertical reinforcement rods should also come up
from the foundation walls and be bent into the slab. This will help
hold the walls to the floor slab. More about this type of construction
can be found in the crawl space/basement section of this chapter.
10. Before the concrete is poured, a means by which the house sill—
the wooden horizontal planks that support the main upper structure of the house—can be secured to the foundation must be
arranged. Anchor bolts can be positioned about every 3 feet
around the perimeter of the slab so they’ll be embedded into the
slab when the slab dries and cures. Check the local building code
for the proper size and spacing of anchors.
11. When the slab is framed and ready to be poured, it should hold the
top of the floor about 8 inches above the ground, and the surrounding grade should be sloped away from the foundation to
keep water running away from the house. If an elevated floor slab
is used, it should be a minimum of 4 inches thick at any part.
137
138
HOW TO BUILD IT
FIGURE 6.9
A foundation that supports a concrete slab.
12. If a smooth finish is desired, specify that the concrete should be
troweled by hand or by power-driven machines. A textured finish
can be obtained by dragging a broom across the surface before the
concrete is fully set.
Advantages
1. They’re very economical to build, especially when compared to
crawl space or full basement foundations. Most slab foundations
take much less labor and time to construct.
2. They’re worm- and rot-proof.
3. They can’t catch fire.
4. They’re basically wearproof and are certainly more secure than
any other kind except solid rock.
FOOTERS AND FOUNDATIONS
5. They can store heat from the earth and are naturals for use in a
passive solar heating system.
6. They require little insulation from the elements.
7. As foundations, slabs are outstanding because they simultaneously act as one gigantic footer. Consequently, they impose the
lowest soil loading per square foot of all foundations.
8. They experience less problems from ground moisture . . . there’s
no leaky basement from a slab.
9. The slab is more adaptable to filled or unstable soils where conventional foundations would settle unevenly and crack.
10. The slab-on-grade foundation eliminates the need to frame a floor
on the first level.
11. They are not affected by underneath drafts.
12. Vinyl flooring and wall-to-wall carpeting can be installed directly
onto the top surface of a slab.
Disadvantages
1. If a problem occurs with a utility that’s concreted into or positioned beneath a slab, it’s extremely expensive and troublesome to
access the malfunction, to make repairs, and to restore the foundation to the way it was.
2. Slab foundations can be efficiently used only on relatively flat
lots. They require substantial site-work when employed on
uneven ground, whereas a crawl space or basement foundation
readily adapts to hilly terrain.
3. Floors constructed over a crawl space or basement foundation are
easier on the feet and legs.
4. Plastic and other moisture barriers must be punctured for pipes
and electrical wires to pass through, thus allowing some underground dampness to rest against the bottom of the slab.
5. Because the slab is mostly below ground, no ventilation reaches
its lower surfaces. The slab tends to adjust to room temperature
very slowly and instead follows fluctuations in ground temperatures whenever they occur.

HOW TO BUILD IT
Concrete and Block Wall Foundations
Many houses built today sit on foundation walls that form either a
crawl space under the house, a partial basement, or a full basement.
These types of foundations are more common in northern locations
where deep frost lines are encountered, but are also found, conditions
permitting, in the South. They’re constructed of either solid poured concrete or concrete blocks, and if either has the edge over the other, it’s concrete blocks. Both foundations will not only support a dwelling, they’ll
also protect it from water, frost, and insects while providing (when
desired) a basement to be used for storage or expanded living space.
If proper foundation construction is not followed, the result will be
a below-standard foundation and possibly a house that tilts, floors that
sag, walls that crack and leak, doors that won’t fit their jambs, and
windows that won’t open or close—all of the same defects that can
also be attributed to a poorly executed footer.
Although crawl spaces are frequently left with soil or gravel floors,
both the solid concrete and the block wall foundation floors should be
poured with concrete to provide cleanliness, to prevent moisture and
insect encroachment, and to supply a useful floor for storage or additional living areas.
The National Building Code requires a foundation to start at least 1
foot below the frost line. Local building codes can tell you how deep
the frost line is in your area. Should bedrock (solid rock) be encountered before the prescribed depth is reached, digging can stop because
bedrock will not move no matter what happens or how cold it gets.
Even if you build where there’s never freezing temperatures, still see
that the foundation is situated at least 1 foot below grade (ground
level) to assure a firm and level base for the framing structure.
Crawl Space Foundations
These foundations are cheaper to construct than basements, and
acceptable when the storage, utility, and living spaces otherwise found
in basements are neither needed nor desired (Fig. 6.10).
Advantages
1. A crawl space foundation is cheaper to construct than a partial or
full basement.
FOOTERS AND FOUNDATIONS
141
F I G U R E 6 .1 0
Crawl space foundations.
2. Because a crawl space is relatively low to the ground, there’s not
much risk of cracked walls.
3. The crawl space foundation takes considerably less time to build,
thus speeding up the overall construction time of the house.
4. A crawl space provides ventilation below the first floor, separating the living areas from contact with the ground and letting
the floor follow suit to the temperatures maintained by the living spaces (unlike a slab, which is more affected by ground
temperatures).
Disadvantages
1. A crawl space foundation is practically useless for storage or living space (for humans).
2. A crawl space can’t accommodate large or tall appliances such as
water heaters or furnaces.
3. Crawl spaces will attract a variety of small furry creatures (notably
rabbits, squirrels, chipmunks, skunks, possums, and mice).
4. Water or sewer lines that run through crawl spaces must be insulated extra well to prevent pipes from freezing.
Partial and Full Basement Foundations
There’s a convincing argument that since the house will be placed
over a footer anyway, you might as well put the potential space below
the regular living level to good use, too (Fig. 6.11).
142
HOW TO BUILD IT
F I G U R E 6 .11
A basement foundation.
Advantages
1. The functional living areas of the house can always be expanded
into a basement’s lower level. A recreation room can be installed
there at a minimal cost.
2. The partial or full basement can easily accommodate a water
heater, furnace, and other major appliances such as freezers, washing machines, and clothes dryers.
3. A basement can include a separate entranceway into the house on
the lowest level.
4. These foundations provide considerable storage and workbench
areas.
5. Like the crawl space, a basement also insulates the main living
areas from the ground.
Disadvantages
1. Basement foundations are more expensive to construct.
2. Because of their height, the walls of a basement foundation are
more likely to crack and develop problems.
3. A basement foundation can at times be virtually out of the question in areas where the water table is high.
FOOTERS AND FOUNDATIONS
143
4. Basement foundations take a relatively long time to construct and
string out the entire housebuilding process.
FOUNDATION CONSTRUCTION
Once you decide on the type of foundation that you think best fits your requirements or is intrinsically suited to the
house you are planning, you then must
decide how that foundation should be
constructed. Three options are concrete
block, poured concrete, and precast concrete walls. All can be used to provide
crawl space foundations (usually built up
from a footer having walls 18 to 24 inches
above ground level), or basement foundations that are typically 7 feet high on the
inside.
Concrete Block Construction
You probably already know what concrete blocks are. They’re rather rough-feeling, heavy, gray, and have several
rectangular holes running through their
insides, vertically (Fig. 6.12). When
installed, they’re laid one course or row on
top of another, staggered so their vertical
joints don’t coincide with each other. The
staggering of joints makes for a stronger
interlocking bond. At the same time, the
center rectangular holes are large enough
to overlap so the courses can be tied
together with reinforcement rods that are
inserted vertically and then filled with wet
concrete.
On a foundation, the concrete blocks
begin at the footer and are laid to form the
desired height of the house foundation or
F I G U R E 6 .1 2

144
HOW TO BUILD IT
basement. On houses using brick exterior finishes, the brick may also
start with the footer and follow the house blocks right up. This will
help support the brick veneer and strengthen the entire foundation.
An alternative for brick exteriors is to go with a wider foundation
block that provides a ledge at the outer top of the foundation walls on
which the brick can be conveniently laid or begun from.
Advantages
1. Concrete block walls permit a stop-and-go schedule during
construction.
2. Concrete block walls are easier to repair than poured concrete walls.
3. Concrete block construction is often preferred by builders costing
out the foundation job because block construction eliminates the
need for concrete forms.
4. Concrete block walls absorb sound better than solid poured walls.
Disadvantages
1. Concrete block walls are strong, but not as strong nor as impenetrable as solid poured concrete walls.
2. A concrete block wall is more likely to develop small cracks that
can allow air infiltration, moisture, and even insects inside the
foundation.
Solid Poured Concrete Construction
Solid poured concrete foundations, even though not as common as
block foundations, are desirable in a number of situations.
Advantages
1. They have a slight advantage in strength and load-carrying capacity over block wall construction.
2. They offer the best protection against air infiltration, moisture,
and insects. They’re also less likely to result in wet basements.
This can be a major advantage where rainy weather is common.
3. They can often be cast integrally with the footer, at a substantial
time and cost savings.
FOOTERS AND FOUNDATIONS
Disadvantages
1. They can be more expensive than block construction.
2. It’s somewhat difficult to be sure that you’ll get as good a mix of
cement as specified. There’s an element of risk involved. It means,
again, dealing only with reputable contractors for the concrete.
Established builders will do so, but vanishing or marginal builders
might not. A defective mix might not be detected until the house
is up and the contractors are long gone. By then it will be a nightmare to correct major flaws or problems.
Precast Concrete Construction
Precast concrete stud wall construction provides an interesting
alternative to concrete-block masonry construction. Precast walls are
strong and capable of being efficiently installed as both foundation
walls and walls above grade.
Precast wall panels are built with steel-reinforced concrete studs
(typically about 71⁄2 by 2 inches), 1-inch rigid insulation board, rebar
reinforced top and bottom bond (footer) beams, along with a concrete
facing about 2 inches thick. The bond beams and concrete facing are
cast in one continuous pour. Studs are connected by encapsulating vertical rebars plus galvanized hooks and pins that protrude from the top,
bottom, and back of each stud. The galvanized pins protruding from the
studs secure an approximately 2-inch-thick face pour. Pressure-treated
furring strips are preattached to the inner face of each stud. This construction provides a base for the homeowner to finish the basement
without having to add any additional studding. Holes are cast into each
stud to accommodate wiring and small-diameter plumbing (Fig. 6.13).
Precast Construction Points
■ Custom-made panels are made to support door and window
openings.
■ All precast panels, and each individual concrete stud, should
include vertical rebar reinforcement. This gives considerable
tensile strength to the entire structure.
■ The rebar-reinforced top bond beam typically has a perforation
about every 24 inches to enable the secure bolting of a sill plate
145

to the top of the wall. The beam also provides strength and
helps to equally distribute the weight of the home.
■ Insulation built into the wall supplies an insulating value of
about R-5. The wall’s cavity, about 71⁄2 inches deep, permits a
thick blanket of insulation to be applied. Combined with the 1-
FOOTERS AND FOUNDATIONS
inch thick polystyrene panels between the concrete studs and
the concrete skin, those components can yield an effective
cumulative rating approaching R-24.
Advantages
1. The panels come with ready-to-finish interior walls. A treated
wood nailer is factory installed to the inside of the reinforced concrete studs, ready for the application of a vapor barrier and wallboard.
2. The panels resist moisture, mold, and mildew well.
3. The insulation panels also provide a thermal break and vapor
barrier.
4. Precast panels can be installed in almost any weather. There’s no
danger of the concrete freezing before it cures or curing too
quickly from excessive heat.
5. These panels save time when being finished in a basement,
because there’s no need for additional framing to support the insulation batts, vapor barrier, and drywall which can be attached
directly to the furring strips with no loss of space.
Foundation Construction Points
Here’s a collection of various construction specs and procedures
used in proper concrete block, poured concrete, and some precast concrete foundations:
1. The minimum thickness for any home in the most ideal situations
requiring minimum loadings is 8 inches. However, 10 inches is
preferable and safer. The minimum thickness should be increased
to 10 inches if the walls will be subjected to any lateral pressures
such as large snowdrifts, if the walls are more than 7 feet below
grade, if the walls are longer than 20 feet, or if the house is going to
carry a heavier than normal load. This can be the case if you elect a
two-story home or if you plan on having considerably heavy furniture and items such as a grand piano, pool table, waterbeds, or
exercise equipment. For extra-deep basements, use 12-inch concrete block. As the block size increases, so should the footer.
147
148
HOW TO BUILD IT
2. Before the foundation floor is concreted, all necessary plumbing
and sewer pipes should be installed. Make sure all pipe cleanouts
are present in the foundation walls and floor. Once the rough
(underground) plumbing is situated in the foundation, the
plumbing inspector may wish to check that the drainage system,
when full of water, will hold up without leaking; check for proper
pipe slope or fall; check the cleanouts; inspect the piping for
proper sizing.
3. Once the foundation walls are up, the floor of the crawl space,
basement, or garage should be filled with 6 to 12 inches of 3⁄4-inch
stone, with 3- to 4-inch drainpipes running through the stone. The
stone (or gravel) should be compacted as it’s put down. Over the
drainpipe and stone, a plastic vapor barrier should be placed to
seal out dampness. This is especially important if the foundation
is a crawl space. A concrete floor at least 4 inches thick will hold
the water and dampness down into the ground, and the drainpipe
will direct the water to a sump hole. Should the sump hole ever
fill up, a sump pump can be installed to pump out the water and
pipe it away from the house.
4. If concrete block is used, the first layer of blocks against the footer
should be special drain blocks with grooved or weep holes along
their bottoms. This will prevent a buildup of water pressure
against the walls. Instead the water will flow into the 6-inch gravel
bed beneath the concrete floor. The drainpipe running through the
gravel will convey the water to the sump hole.
5. Along the outside of the foundation, 4-inch rigid plastic pipe having openings or perforations along the top should be placed endto-end on a gravel base along the footer, pitched toward the spot
where the water will be piped away from the house. This pipe
should be lower than the basement floor and not simply resting on
the footer. With this setup, water flowing against the wall of a
home has a place to go. These drainage pipes need to be continuously sloped toward the discharge end; otherwise, sediment might
build up at a low point and completely block the line. If the soil is
full of clay or silt, consider installing a soil-filtering fabric to protect the stone and the drain piping from becoming plugged with
sediment washed down from the backfill. The water table should
FOOTERS AND FOUNDATIONS
be maintained no higher than the elevation of the pipe under the
entire basement or crawl space so water pressure is held at a minimum. This perimeter drainage pipe system should be covered
with approximately 12 inches of 3⁄4-inch stone.
6. On some lots there is no place to discharge the house drain pipe
from the foundation to daylight. In this situation, footer drains can
be run inside to the basement sump hole.
7. A sump pump should be installed in the foundation floor when
necessary (Fig. 6.14). Some foundations, either crawl space or
basement types, might never need one, while others may have to
employ one year-round. Many building codes have been making it
mandatory to include a sump hole so a pump can be added later,
if needed. For the most part, sump pumps are set up so that if
water backs up to a certain level and threatens to flood the cellar,
the pump will automatically kick in and pump out the water into
an outside drainage line that will carry it away from the house.
The sump hole itself should be 24 inches in diameter or 20 inches
square and should extend at least 30 inches below the bottom of
the basement or crawl space floor. The sump hole should be covered to prevent people and pets from stepping into it and moisture
from escaping it into the basement.
8. One aspect of the foundation that deserves special attention is
waterproofing. Damages due to water and moisture are among the
most serious causes of home deterioration. They cause wood rot,
unsightly paint peeling, mildew, rusted appliances, and other maladies. They can even affect the health of the occupants. To prevent
damp and wet basements, good waterproofing techniques, proper
drainage, vapor barriers, correctly graded lots, appropriate landscaping and positioning of shrubs and trees, generous roof overhangs, and plenty of gutters and downspouts are necessary.
9. If you’re going to have a basement, have the septic disposal system
line or the sewer line located below the basement floor if possible.
Otherwise, wastewater and solids generated in the basement have
to be pumped up to the level of the main lines for disposal. If the
disposal lines cannot be lowered, the simplest solution is often to
completely avoid any sanitary drains in the basement (that means
no toilets, wash basins, showers, or laundry equipment). Then the

house sewer or septic lines can be suspended beneath the first-floor
joists and run through openings cut in the foundation walls. The
same thing can be done with a crawl space foundation if necessary,
as long as precautions are taken to prevent the lines from freezing.
FOUNDATION REINFORCEMENT
Reinforcement of a foundation’s floor and walls is a critical part of
the housebuilding process that can be easily slighted by marginal
builders. Most home buyers don’t realize what’s involved and depend
solely on the recommendations of contractors who can, at times,
underemphasize the specs that are needed for a sturdy foundation.
FOOTERS AND FOUNDATIONS
F
OCUS
WATERPROOFING
Wet and damp basements can be more than just uncomfortable.
Unchecked moisture allows mold and fungi to flourish, which can cause
allergic reactions in people and pets and can result in peeling paint;
rotting wood; and warped drywall or other wall, floor, and ceiling components.
With either a basement or slab foundation, in addition to applying a
1
⁄2 inch of parging masonry (or cement) on the outside surface of basement walls, followed by two coats of a bituminous tar sealant, make
sure good drainage is achieved around the entire dwelling. Grading or
sloping the soil away from the home’s perimeter is essential to effectively controlling roof and outside wall water runoff. As a rule of thumb,
the soil should slope downward at least 6 vertical inches in the first 10
horizontal feet of travel from the foundation wall or outer vertical surface of the slab.
Some of the best drainage systems direct water that comes near the
foundation down toward the level of the home’s footing, where clay, concrete, or plastic drainage tiles or pipes collect and convey the water away
from the dwelling, or collect and discharge the water through a sump
pump. For drainage lines to work efficiently, they must be securely
installed in beds of porous material—usually washed gravel. To achieve
good drainage at window wells, the washed gravel should continue from
the bottom of the wells to the foundation drainage tile. The window well
should be wider than the window and frame and deep enough for at least
two inches of washed gravel to be placed at the bottom of the well—
while staying below the lower portion of the window’s frame. It’s important to prevent any chance of water getting up to any part of the
window’s frame.
To address the “open” nature of window wells, galvanized steel
window wells are available to hold back the earth, and sturdy grating
should be fitted at the well’s top to prevent someone from stepping
into the well. Plastic covers can also be placed over the top of window
wells to keep out rain and snow.
Downspouts that carry rainwater away from roof gutters should be
connected to a mostly horizontal (slightly sloped) length of pipe that
carries the water several feet away from the foundation. If a sidewalk is
in the way, drain tile can be used to run the water beneath the walk to
open ground or a catch basin, depending on the landscaping serviced. If
151
152
HOW TO BUILD IT
a downspout empties into a catch basin, then into a drain pipe, the
catch basin should be positioned far enough away from the foundation
so runoff during a heavy rain will not overshoot it and yet close enough
to catch the slower flow during a light rain. The water can also be conveyed to a bubbler or “dry well” where the water is allowed to simply
drain off or dissipate into the surrounding ground. Bubblers or dry wells
should never be located within the drip line of large trees—where the
soil could become saturated for long periods of time and could allow
the tree to fall over (roots and all) in high winds.
On flat or level building sites where there’s no room for or possibility
of establishing surface drainage slopes, a “trunk and arm” drainage system can help handle water runoff (Fig. 6.15). Such a drainage system
consists of a perforated drain tile (usually 6-inch diameter), which acts
as the trunk and runs parallel to the home’s foundation, and solid drain
tiles (usually 4-inch diameter), which act as the arms, attached to the
trunk with T connectors. The arm tiles run perpendicular to the trunk,
spaced about 10 feet apart from each other and slope underground to
dry wells filled with washed gravel, where the surface runoff water can
collect and slowly dissipate into the surrounding earth.

This cost-cutting philosophy can lead to
big problems later, at the homeowner’s
expense.
Here are some guidelines for the reinforcement of foundation floors and walls:
1. A concrete floor should be strengthened with reinforcement rebar. The
rebar should be elevated to the middle
of the floor’s thickness on steel bridges
or chairs set so they’re positioned
evenly across the floor before the concrete is poured with ends overlapped.
If welded wire fabric is used along
with the rebar, its joints should overlap. Material overlap should meet
local building code.
F I G U R E 6 .1 6
Foundation block pilaster.
2. If a foundation has long walls or walls
subjected to above-average stresses, they can be strengthened with
pilasters (Fig. 6.16). A pilaster is a vertical block or concrete column poured or constructed adjacent to or adjoining a foundation
wall, located at about the middle of the wall’s length. More
pilasters are often needed along unusually long walls. By having
thicker walls at selected points, this extra support lessens the overall stress on the walls and helps prevent cracking. Steel rebar at
least 5⁄8-inch thick, with four rebars to a set should be installed in
and extend the full height of the concrete-filled pilaster voids.
3. Another modern and commonly used method of reinforcing the
walls of a foundation is to place long pieces of 5⁄8-inch-thick rebar
the length of the wall, in sets of four, through the rectangular openings of every other concrete block, vertically, and then to fill in
those reinforced holes or “cores” solidly with concrete (Fig. 6.17).
The same rebar can also be embedded in the footing pour as a tie
from wall to base, especially when high walls must withstand considerable pressures from slopes, water, or backfilling. All house
foundations should have either the pilasters or the reinforcement
rebar for vertical support. For a stronger foundation wall, use both
pilasters and vertical reinforcement rebar throughout the walls.
154
HOW TO BUILD IT
4. For horizontal support, reinforcement
wire should be placed in the mortar
bed joint of every other course of
blocks (Fig. 6.18).
5. Block walls that are quickly erected
and backfilled require bracing within
the crawl space or basement for temporary support until the concrete and
mortar dries, to make sure the structure is tightly knit before stresses are
applied. Leave temporary wood supports up in the basement as long as
possible, especially during and after
backfilling takes place.

6. Load-bearing foundation walls should
not be joined or tied together with a
masonry bond unless the walls join at
a corner. Instead, steel tie bars vertically spaced not further than 4 feet
apart (check local building code) will
form a strong bond (Fig. 6.19). If the
walls are concrete block, strips of lath

or steel mesh can be laid across the
common joints in alternate layers or
courses (Fig. 6.20). If a nonbearing
wall will be constructed at a later date,
ties should be incorporated into the
first wall, to be left half-exposed so
they’ll be available when needed for
the second adjoining wall.
Masonry Joints

walls, you have an option to select any of
the following mortar joint types that
would best go with your style of construction: flush, struck, V, concave, raked, beaded, extruded, and weathered (Fig. 6.21). The V and
concave versions are the most popular since they look neat and do not
form a miniledge that could accumulate water. Beneath the grade, or
the ground level, where appearance does not count, the joints are typically left flush.
Concrete Forms
If you’re using poured concrete walls, make sure you realize that
the quality of the concrete forms directly affects the finished appearance of the walls. Concrete forms must be tight, smooth, defect-free,
properly aligned, and well-braced to resist lateral pressures created by
the poured concrete.
FOUNDATION FLOOR SUB-BASES AND FLOORS
The floor sub-base should consist of a compacted layer of 3⁄4-inch
stone 4 inches thick. Plastic sheathing that comes in 4- or 6-mil thicknesses or other suitable vapor barrier materials are placed over the
subbase to form an effective insulating moisture barrier before the
floor concrete is poured.
The concrete floor should be a minimum of 4 inches thick, with
welded wire mesh and rebar running through it for strength, and the concrete should be sloped to the floor drains. If you desire a smooth finish on
a basement floor, it will be necessary to specify that you want the concrete
steel-troweled. Should you desire a textured finish, it can be obtained by
having brooms dragged across the surface before the concrete is set.
156
HOW TO BUILD IT
FOUNDATION WALL TOPS
On top of all foundation walls anchor
bolts (Figs. 6.22 and 6.23) should be
installed or partially embedded at approximately 3-foot intervals (check local building code), with protruding bolt lengths
long enough to securely fasten the sill
plates (wooden planks that join the upper
framing structure to the foundation).
Have foundation walls constructed of
concrete block capped with a course of solid
masonry blocks that will act as an insect
barrier and help distribute the weight of the
house’s upper structure. When solid blocks
are not used, the cores or rectangular holes
in the top course can be solidly filled with
mortar or concrete. To do this, a strip of thin
metal lath must be placed in the mortar joint
under the top course. The strip, which is
just wide enough to cover the block cavities,
forms a base for the concrete that fills the
top course cavities.
WALL COVERINGS AND INSULATION FOR
THE FOUNDATION
Exterior
FIGURE 6.21

The foundation will be less susceptible
to frost damage, moisture transfer, leaking,
and insects if the walls are insulated on
the outside (Fig. 6.24). Concrete block
walls should be pargeted (plastered) with
a 1⁄2-inch of cement mortar.
The half inch of mortar can be applied
in two coats for superior holding power.
Apply 1⁄4-inch thick layer of portland
cement to a moistened masonry wall. The

first coating should be put on roughly and allowed to dry for 24 hours.
When ready for the second coating, the first should be moistened, then
the second 1⁄4-inch coating can be smoothed over the first and kept
moist for about 48 hours while it hardens.
For any foundation wall, request two coats of tar or bituminous
waterproofing material to be troweled on. Troweled tar is the best, but
brushed on or sprayed on waterproofing is better than nothing. If local
weather conditions are severe, protection can be further improved with
a layer of sheet polyethylene or asphalt-impregnated membrane. Make
sure there are no sharp surfaces that could tear or damage the membrane
when the membrane is applied. Remove any large rocks or roots from
the backfill so the poly membrane won’t be damaged during backfilling.
Internal insulation inside the blocks can be accomplished by
installing rigid foam insulation inserts that are friction fit into conventional block holes before the block is laid to increase R-values. Block

holes that will be concrete filled are skipped. This type of insulation is
out of view and protected from the elements. (See Fig. 6.25.)
Exterior insulation can be installed using extruded polystyrene
rigid foam that’s 11⁄2 or 2 inches thick tongue and groove for a good
seal. It will provide good thermal protection and moisture resistance
above and below grade. The joints should be taped with product from
the manufacturer. The manufacturer will supply installation instructions.
Above-grade foundation wall exteriors can also be protected with
stucco or treated plywood.
Interior
To reduce heat loss, to prevent moisture and water leakage, and to
further prevent the possibility of insect penetration, foundation interior walls can be insulated and covered.
A thick waterproofing white paint that’s brushed onto the interior
surface will reduce moisture penetration and discourage insects from

infiltrating interior walls (Fig. 6.26). Foundation wall interiors can be insulated by
first putting up furring strips and then
applying blanket insulation in the usual
way (Fig. 6.27).
FLOOR SUPPORT BEAMS OR GIRDERS
To support the house, one or more girders (load-bearing beams that help support
the first-floor joists) as determined by the
contractor’s structural engineer should be
installed. Steel I beams make the most reliable girders, but wood girders constructed
of planks joined together by bolts or nails
are also used (Fig. 6.28). Steel I beams are
rather consistent in quality. The wood
girders will vary in quality because they’re
dependent on the quality of their individual component planks. Girders either rest
in pockets formed in the tops of the foun-

dation walls or on top of corresponding
masonry pilasters. In any event, the steel
girder tops are generally made flush with
the top of the wooden sill with wood
planking that’s laid along the top of the
entire steel beam (Fig. 6.29).
FOUNDATION VENTILATION
Ventilation in foundation walls can be
accomplished either with windows or
with vents. Basement windows are discussed in the chapter on windows. If vents
are decided upon, have them installed
near or at the top course of concrete
FIGURE 6.27
blocks, or as high as possible in the founFoundation wall furring strips and insulation.
dation walls at the rate of one every 50 linear feet, each being about the size of a
concrete block: 8 by 16 inches (Fig. 6.30). They should be the type that
can be closed during cold weather. At least one vent should be positioned at each corner of the house, with cross ventilation arranged for
a minimum of two opposite sides. If the house is located in an area
experiencing high humidity during much of the year, increase the
number of vents to one for every 15 linear feet.
On a crawl space foundation, in addition to vents, there should be
at least one access door of not less than 32 by 36 inches installed. If it’s
a large crawl space of 2,000 square feet or more, or an unusual shape,
more than one access door should be included. Confirm this with local
building codes.
BACKFILLING
Once the foundation work has been completed and before backfilling occurs, you should make a formal inspection. Backfilling is simply
the pushing back of excavated soil around the house to fill in the construction ditches. Backfilling should only occur after the first floor is
framed and the walls are framed up so the added weight of the structure will stiffen the walls and make them less likely to bulge from the
pressure of the backfilled soil.

HOW TO BUILD IT
FIGURE 6.30
Foundation wall vents.
To avoid subjecting a “green” foundation that isn’t fully cured to
pressures that could damage it, plank or timber bracing should be
installed inside the crawl space or basement, supporting the walls at
about 12-foot intervals. The house’s central longitudinal support beam
or girder, plus the first-floor joists and floor decking should also be
erected to help strengthen the foundation walls before backfilling
takes place.
As a general rule, backfill height from footer to grade should not
exceed about 7 feet.
FOOTERS AND FOUNDATIONS
The waterproofing must be protected during the backfilling, since
rocks and other hard materials in the backfill could scratch and penetrate the waterproofing and allow moisture seepage. If the soil that will
be pushed back contains large rocks, the contractor should apply 4 by
8-foot or 4 by 10-foot sheets of impregnated sheathing or equal material
for protection. The final grade must slope away from the foundation.
F OCUS
STORM SHELTERS
Sometimes referred to as tornado shelters, these units are typically set
within the ground and temporarily protect household members who may
seek shelter during major storms. A good time to have one installed, of
course, is when the home’s foundation is being constructed and the backhoe or other piece of heavy equipment is already there anyway to excavate.
The most popular types of storm shelters are manufactured out of
fiberglass—a forgiving material that withstands considerable movement
and settling of earth, resists corrosion, mold, and mildew, and is very
durable (Fig. 6.31). Units are available that seat up to 10 adults. These
shelters are often anchored at the bottom of excavations, in poured concrete foundations that hold the units below ground level. To provide
enough air for the inhabitants to breathe, storm shelters need multiple
ducts and vents that rise far enough above the ground to prevent surface water and runoff from entering. The vent openings should also be
covered with insect screens.
Outside doors should be low profile to permit simple landscaping and
to avoid tornado or hurricane winds from affecting the unit.
Some of the more important features found in storm shelters include
the following:
■

Prewiring for a television and phone. This would allow shelter users
to stay in contact with what’s in the news or what’s going on outside, and to phone for help in case problems occur.

Skid-resistant steps with handrails.
A lifting jack inside the unit, in case the doors become blocked by
a downed tree branch, for instance.
A carpeted floor.
163
164
HOW TO BUILD IT
Other alternatives for tornado- or hurricane-resistant home protection
include “in-residence shelters,” which employ more conventional construction methods to encase an interior room of a house with concrete
or steel and to then bolt the reinforced room to the foundation. Such
rooms can have practical uses as well—as closets, storage areas, or even
photographic darkrooms.
FIGURE 6.31

SAFETY >>>NOTE
With any storm shelter, make sure that a number of relatives, friends,
or neighbors know of its existence and get them to agree to come looking for you following a major storm if you don’t check with them immediately afterward.

ROOT CELLARS
A root cellar may sound a bit old fashioned, but for households fond
of gardening, farming, and cooking, a root cellar can be an interesting
and useful addition. Root cellars are still standard fare in Europe and
many other parts of the world—small- to medium-sized rooms or portions of cellars carved out of or built into the earth. Their name has
evolved from two of their characteristics: root cellars have been used
for centuries to store root vegetables such as potatoes, carrots,
parsnips, turnips, and onions (as well as canned and pickled foods)
that keep longer in dark, cool places; and second, because roots of
trees and live plants had often grown directly into the root cellar over
the years.
The perfect time to build a root cellar is when the excavation and
foundation are under way. Because a root cellar needs to be shaded
from sunlight, the basement provides the best location, where it will
help resist temperature swings and has a natural ability to keep stored
items cool. One way is to take a corner of the basement—a northern
corner, if possible—with the greatest exposure to cold outer walls (concrete or concrete block) and frame in a rectangular room (large enough
to suit your needs) with insulated studded walls. Another way—if the
home will have a concrete porch or patio that rests on top of a full
foundation wall—is to simply build the root cellar within that part of
the foundation wall. It’s typically a large enough area and will need
only one insulated wall and door to enclose.
A third option is a root cellar that has three sides carved out of the
soil, again, so only one insulated wall and door separates the space
from the rest of the basement. Any enclosing wall (or walls) should use
2 by 6 inch studs with fiberglass or rigid foam insulation. The ceiling
needs to be insulated as well. Protect both sides of insulation from
moisture in the air with polyethylene air-vapor barriers. The ceiling
needs the same barriers running up and around each joist, above the
insulation, and below the insulation, too. A finish layer of drywall can
be placed over the insulation and air-vapor barriers to protect against
punctures. For access, an insulated steel door will do a good job here
with a tight seal around its edges and extra rigid foam insulation bolted
to the inside of the door with large flat washers. Because the door
needn’t be fancy, contractors often suggest making it out of 2 by 2s,
165
166
HOW TO BUILD IT
2 by 4s, and plywood. Wood doors, however, will likely warp over the
long haul, and lose their temperature-tight seal.
A root cellar must also be ventilated. A small louvered metal vent the
size of a concrete block works well. The louvers can be adjusted or
closed as needed throughout the year.
Last, make sure the contractor builds and installs whatever shelving
you need to maximize storage space (Fig. 6.32).
FIGURE 6.32
Root cellar shelving.
POLE AND PIER FOUNDATIONS
A less frequently used foundation is the pole and pier arrangement
(Fig. 6.33). It’s a good setup for small homes built in steep terrain, or
for vacation homes and cottages. Poles or piers are firmly implanted
into solid ground so they’re stationary (frequently cemented right into
FOOTERS AND FOUNDATIONS
167
the ground) and then the frame of the
house is constructed on top of them. For
this type of foundation, concrete tubes
(concrete-filled cardboard cylinders) and
telephone poles are very popular.
Advantages
1. It lends itself to steep terrain where
there is considerable variation in the
height of the piers and where a regular
masonry foundation is impractical.
2. Grading isn’t required. There’s a minimum of site preparation involved.
3. It’s an inexpensive foundation and
easy to build.
4. There’s plenty of natural ventilation
between the ground and the living
levels.
FIGURE 6.33
A post and pier foundation.
Disadvantages
1. With the underside floor surface fully exposed to the elements, in
cold climates the floor must be exceptionally well insulated.
2. It allows wind and small creatures to get beneath the building.
3. It is practically useless for any kind of storage or future expansion.
MISCELLANEOUS ITEMS
1. In locations with large populations of termites or carpenter ants,
consult a qualified pest-control company to provide appropriate
treatment. The company should provide a guarantee on their work
that covers repairs if insects re-infest the treated areas.
2. Specify if you want windows in your foundation: their size and
make, how many, and their location if in a full or partial basement.
3. Specify if you want a rear or side outdoor entrance to the basement.
Use concrete or steel lintels for door openings. Precast lintels are
168
HOW TO BUILD IT
simple to install because they’re made to match the height and
width of concrete blocks. They should be long enough to overlap
(per building code) on the bearing block. Another method involves
forming and pouring a lintel on the site, using wood forms and
reinforcement rods.
The outside stairwells should begin at a point lower than the
basement floor, to prevent water from entering the house. A 6-inch
sill protecting the basement door is standard. Or, a built-up curb
could be constructed as a partial remedy. A decision should also
be made if you want the stairwell opening covered by steel doors.
4. Don’t let the contractors confuse the topsoil that was pushed to the
side when the construction first began with the soil that was excavated for the foundation. The topsoil should only be used for finished site grading, not as backfill around the foundation.
Trees you want saved should be marked with bright ribbons or
spray paint so the contractors won’t damage or knock them down.
The agreement should specify that all scrap tree stumps and brush
must be pulled out and hauled away. If you get your builder to
agree up front, hardwood trees that need to be removed could be
cut up and piled for firewood.
5. It’s not a common request, but poured concrete walls and floors
can be colored by the addition (when wet concrete is being mixed)
of mineral pigments sold by ready-mix concrete and block producers, lumberyards, and building material dealers. Reds, greens,
yellows, browns, grays, and other colors are available.
6. If you’re going to have a full basement, and you plan to eventually
put in a recreation room, try to locate it as closely as possible to
the basement stairs. Opt for larger windows than normal so the
room will have adequate light and ventilation during the day.
Check building code requirements related to any partitions you
plan to install around the furnace and water heater; you might
have to meet clearance and surfacing requirements.
Avoid placing partitions, present or future, too close to plumbingheating-electrical elements such as sump pumps, water meters, shutoff valves, and waste cleanouts. Give them an extra inch or two
clearance to permit quick access in case of trouble.
FOOTERS AND FOUNDATIONS
When possible, plan a workshop area close to an outside access and
also near an unexcavated sheltered area where a crawl space can be
used for lumber and storage of other long materials.
The typical cellar wall should be 11 courses high (or 88 inches).
But if any rooms on the floor above it will be sunken, consider an extra
course (12 courses total) in case you someday decide to finish off the
basement. If you go the extra block, you’ll still be able to have a normal
ceiling height when finished.
All basements should have at least one water drain in the floor, and
those cellars larger than 900 square feet should have two drains. The
floor should taper toward the drains, and the drains should transport
water to the house’s sump hole or exit drain.
The local building code and the contractor’s engineer should specify properly sized steel beams, girders, and vertical columns.
➤➤➤➤➤ POINTS TO PONDER
1. The main goal of a footer is to evenly spread or distribute the
weight of a house over a large enough area of soil so that settling or moving of the dwelling never occurs.
2. If the building site you select consists of recently filled loose
soil, the loose soil must be either excavated out, compacted
through mechanical means, or built upon by custom engineering and construction of a footer for the exact home you are
building.
3. The frost line must always be taken into account when constructing footers and foundations. If a footer is not placed below the
frost line, the alternate expansion and contraction of the earth
above the frost line might cause the footer to move—to heave
upward or list downward—causing cracks in rigid concrete footers and foundations, with their accompanying ill effects.
4. The type and condition of the soil must be taken into account;
check it by having a soil test hole dug. Organic types of soils (such
as peat) groundwater content, and large tree root systems can all
interfere with traditional concrete footers and foundations.
5. Paying special attention to the sewer or septic lines prior to
pouring a footer will help prevent basic sewage and drainage
problems.
169
170
HOW TO BUILD IT
6. Concrete foundations should extend above the final grade
enough so that wood members of the house are some distance
above the soil, for protection against moisture and insects.
7. Concrete block or panel or poured concrete foundation walls
enclosing a basement should be a minimum of 7 feet high, from
the basement floor, and consider up to 9 feet if you know you’ll
be finishing off parts of the basement later.
8. Achieving efficient outside drainage around a home’s foundation is absolutely critical to prevent basements from developing moisture and leaks. So are good waterproofing techniques,
vapor barriers, correctly graded lots, appropriate landscaping
and positioning of shrubs and trees, generous roof overhangs,
and plenty of gutters and downspouts.
9. Don’t allow the contractors to confuse the topsoil that was
pushed to the side when the excavation first began with the soil
that was excavated for the foundation. The topsoil should only
be used for finished site grading, not as backfill around the
foundation.
10. Consider the addition of a root cellar and/or storm shelter to be
excavated at the same time your home’s footer and foundation
are being installed.
CHAPTER
7
Floor Framing
T
he wood frame of a house has been compared to the skeleton in a
human body, in that it forms the shape and size and provides the
strength to a dwelling. Even with a brick house (in today’s modern
construction this usually means brick veneer), the framing actually
supports the brick, not the reverse as many people think. It’s critical
that the framing be erected correctly; it’s not an area in which to
compromise to reduce costs. Any errors discovered after the framing is
complete are likely to be expensive to correct.
As a rule, the sills, girders, floor joists, and subflooring are the first
members of the wood-framed structure placed on the foundation walls.
These are followed by the outside wall studding and corner posts.
LUMBER
All the lumber used should be air- or kiln-dried and of No. 2 grade
or better. Regular lumber while seasoning after it’s nailed in place, can
shrink away from the shank of a nail, reducing friction between the nail
and the surrounding wood and causing nail popping, the protrusion of
heads of nails from lumber they had previously been nailed flat against.
Besides an increase in strength and nail-holding power, air- or kilndried lumber holds screws and glue better, and results in superior

adherence of paints and preservatives. It’s also a better thermal insulator than regular lumber, and is less likely to be attacked by fungi or
insects. Only pressure-treated lumber should be used for framing
members that are exposed to moisture.
Here are some guidelines:
■
.25 CCA (pounds salt solution per cubic foot) for above-grade
applications, such as decks and railings.
■
.40 CCA for lumber that comes in contact with the ground, such
as columns supporting decks.
■
.60 CCA for lumber located below grade, such as in an all-wood
foundation.
SILL PLATES
The sill or sill plate is the timber (usually made of 2 by 10-foot
wood planks) that’s secured to the top of the foundation walls to form
a link between the foundation and the home’s upper structure.
Some sill plates are laid in a bed of wet mortar. Most, however, are
installed in the following manner: anchor bolts are partially embedded
in the concrete foundation wall tops, then a resilient, waterproof layer
of sealer (similar to felt or Styrofoam) is pushed over the protruding
bolts down onto the top surface of the foundation walls. The sill plate,
having holes drilled in it to correspond with each anchor bolt, is then
placed over the bolts onto the fiberglass layer, pressing the fiberglass
flat against the top of the foundation walls. The sill plate is secured
along the foundation top with sturdy lock washers and nuts tightened
onto each anchor bolt (Fig. 7.1).
SUPPORT BEAMS OR GIRDERS, AND POSTS
As mentioned in chapter 6, floor joists that traverse long spans
between foundation walls must be supported by longitudinal beams or
girders. These structural members can be steel I beams (the best alternative) or wood planks nailed or bolted together, as determined by the
contractor’s engineer. The ends of these longitudinal beams or girders
rest either on pockets (rebar/poured concrete reinforced) in the foundation walls, or on concrete block or poured pilasters. The girders
FLOOR FRAMING
173
should bear or rest on each foundation
wall. The top surface of a longitudinal
beam or girder must be made level with
the top surface of the foundation wall via a
wood plank secured on top.
Vertical posts of steel support the
beams or girders through the interior of the
span (Fig. 7.2). To prevent sinking, the vertical posts should be located over piers
(concrete-filled holes about 18 inches
across and 8 inches deep) set in a gravel
floor or beneath a concrete floor so the
weight the posts support will be distributed over a broad area.
F I G U R E 7.1
FLOOR JOISTS
Securing and sealing the sill plate.
Floor joists are horizontal structural
planks placed on edge against a house’s
sill plate in an orderly fashion to distribute
the weight of the wood framing to girders
and sills and to provide a base for floor
decking. Joist ends rest both on the sill
plates and on interior longitudinal girders
of steel or wood (Fig. 7.3). The joists
should be of sufficient strength, stiffness,
and number to support the floor loads over
the area spanned, with no perceivable
deflection or “give” that could result in
cracked plaster or pulled-apart drywall
seams.
In good construction, joists are placed
either 12 or 16 inches on center, and are
made of planks 2 by 10 inches or 2 by 12
inches. Planks running around outside
wall perimeters that floor joists are fastened to are called headers (Fig. 7.4).

F I G U R E 7. 3
Floor joists support.
Double-thickness floor joists—two planks fastened together—
should be used in certain situations, for example, wherever the first- or
second-floor walls run parallel to the floor joists. This will also occur
at openings around a stairway (Fig. 7.5), near a fireplace chimney, or at
any major change in joist direction such as where partitions are built
to provide clearance for hot air ducts and returns, under cast-iron
bathtubs, or to provide additional support where joists cross a girder
(Fig. 7.6).
When choosing the floor joist material, ask your builder about engineered wood I-beam floor joists. Engineered wood I beams are made
with a top and bottom lumber flange (typically 2 by 3 inches or 2 by 4
inches) with a grooved center to accommodate a center web (typically
plywood) (Fig. 7.7). Special hangers with blocking are needed to
secure these beams.
Engineered wood I-beam floor joists offer many advantages:

back from the edges.
■ There is more bearing surface for glue and support.
■ Typically lighter than dimensional lumber.
■ Can come with predrilled knockouts for wire and plumbing.
HEADERS
Again, a floor-framing header is a wood plank that the floor joists
are nailed perpendicular against on two opposite sides of the house,
and parallel against on the other sides. It’s erected vertically on its long
edge, resting on the sill plate along the exterior of the foundation
walls. Many contractors also use the term “rim joists” when referring
to the floor header joists.
FLOOR DECKING
A number of structural materials, mostly wood or composition
wood products, are used to cover floor joists and to construct the firstfloor platform on which all subsequent house framing rests. These are
mainly walls that are bearing units for the upper floors and the roof
structure, and walls that form interior partitions. The most popular
materials are plywood, hardwood boards, and particleboard. Thicknesses of the floor should range from 11⁄8-inch and thicker. Remember
to consider what you’re going to have as furnishings. For example, if a
room is expected to include a complete set of Olympic weights, with a
variety of exercise benches and machines, it will likely require a
thicker floor.
Plywood is one of the strongest and most convenient floor materials
available. It not only makes an effective floor, but also serves as a strong
structural tie between the floor joists and wood beams or girders.
Hardwood boards are available in many sizes and thicknesses.
They are often used as floor coverings, and alone over the joists as the
main floor structure as well.
Particleboard is popular because of its low cost and lack of sheet
curvature (it’s stiff and straight). When used with an underlayer of plywood, what results is a thick, sturdy floor. If you use a two-layer floor
177
178
HOW TO BUILD IT
with particleboard as your second layer, do not leave this material
exposed to the weather. It will absorb moisture and swell up.
An excellent all-around floor construction consists first of 5⁄8-inch
thick (or thicker) plywood sheets glued and screwed to the floor joists.
The glue helps eliminate squeaks and nail popping and increases
the stiffness of the plywood-to-beam bond from 10 to 90 percent. In
fact, the adhesion of mastic-type glue is so strong that plywood and
joists tend to behave like integral T-beam units. Screwing the flooring
to the joists is superior to nailing. Screws have proven the most efficient; they’ll help prevent springiness, uplift, horizontal shifting,
warpage, and nail-head popping. When used along with glue, they’ll
provide a trouble-free floor.
The plywood and other sheet materials should always be attached
so that the joints don’t line up in a regular fashion (Fig. 7.8). On the

first layer of flooring, it’s best to arrange the plywood sheets so their
lengths run at right angles to the joists for maximum strength. Once the
4 by 8-foot sheets of plywood are laid down, they should be covered
with 15-pound asphalt-saturated felt paper. Then a second structural
layer of particleboard (5⁄8-inch) sheets can be fastened to the plywood—
again staggered so none of the seams coincide (Fig. 7.9). If additional
strength is desired, the second layer can also be plywood sheets (5⁄8inch). In either case, the result will be a sturdy, quiet floor.
When you select plywood, make sure that the contractor uses a
good CDX grade, one that contains exterior glue lines on both sides.
This grade of plywood, made with an exterior-type glue that is waterproof, will stand up to prolonged exposure to the elements during construction. The bottom plywood layer is first screwed down with an
automatic screw gun, it should then be screwed along the vital joints—
where one piece of plywood faces another—to prevent squeaking.
Gaps of 1⁄16-inch or more, depending on the humidity levels in your
area, should be left between the sheet edges and end joints in all plywood layers. Plywood expands when it absorbs moisture and will
buckle if it doesn’t have enough room. Higher humidity areas may

require more of a gap for
expansion. Even correctly installed singlelayer floors will squeak
and give if the sheets are
too thin. Use 11⁄8-inchthick tongue-and-groove
plywood
if you’re going with a
single layer. Plywood
used for single-layer
construction
should
have an approved APA
stamp on it, or be of
equal quality (Fig. 7.10).

Association—the “APA”

mills produce about 75
percent of structural
wood panel products
made in North America.
In any event, plywood subflooring should
always end directly over
a joist. The subflooring
stabilizes the joists and
keeps them from twisting or buckling.
CAULKING
Make sure that parallel beads of caulk are run between the bottom
of the floor decking and the sole plate as well as between the top of the
FLOOR FRAMING
181
floor decking and the outside wall framing. This will reduce the loss of heat due to
air infiltration.
BRIDGING AND BLOCKING
To stabilize the floor joists, bridging or
blocking must be used. They help keep
the joists properly aligned so the floor
decking has a continuously level base to
rest upon (Figs. 7.11, 7.12, and 7.13).
Bridging consists of pieces of wood (or
sometimes metal), usually 1 by 3 inches, Metal bridging of floor joists.
nailed crossways between the top and bottom of adjacent joists at about the center of each joist span. There
should be no more than 8 feet between individual rows of bridging,
and nailing is easier if the bridging is slightly staggered along individual rows (Fig. 7.14).
Blocking refers to 2 by 10-inch or 2 by 12-inch wood blocks fit and
nailed firmly between joists at the center of each joist span. Again,
there should be no more than 8 feet between individual rows of blocks.
Blocking not only holds the joists parallel and plumb, but will also
act as a firestop that will retard the horizontal spread of flames. In
homes where bridging is used to support the floor joists, a row of
blocking can also be installed for fire protection.

STONE AND TILE FLOORS
If your plans call for stone or tile floors in areas other than bathrooms, allow additional space where needed for the setting of stone or
tile in a thin bed of cement by dropping the floor decking.
FLOOR EXTENSIONS
Give careful consideration to house designs that call for floor extensions that protrude outside the basic perimeter of the walls. They
FLOOR FRAMING
might be needed for such features as porches, second-story overhangs
or decks, or bay windows. A sizeable protrusion could require supports outside of the foundation wall or even an actual adjustment to
the foundation.
TERMITE CONTROL
Termites frequently enter a housing structure near the first-floor
level. It’s best to consult a qualified pest-control company to make
sure the necessary treatment is provided. The best companies give a
lifetime guarantee on their work that will cover repairs if insect damages eventually result. Construction design precautions include, on a
hollow-block foundation, filling the top courses of block with concrete, and installing a metal termite shield along the foundation wall.
Such a shield must be made of noncorroding metal and must be
installed so no gaps exist along seams or where the shield is
attached. This continuous strip of thin metal, attached between the
foundation and sill plate, should extend at least 2 inches out and 2
inches down from the foundation wall, bent downward at a 45degree angle.
FLOOR INSULATION
The usual procedure for installing an effective vapor barrier is to
place 15-pound building paper between the first and second layers of
floor decking (if there are two layers), or else between the only layer of
structural floor decking and the floor covering (Fig. 7.15). In addition,
if required by your climate and house type, blanket or batt insulation
can be installed between the floor joists beneath the floor decking. An
integral vapor barrier should also be situated against the underside of
the floor decking. This will prevent the movement of moisture from
the living area into the insulation.
Insulation from noise can be an important feature in a home. An
example of a soundproof type of floor, starting at the top, consists of a
layer of carpet, the carpet pad, a 5⁄8-inch plywood top floor deck, a layer
of 15-pound felt paper, a 5⁄8-inch plywood bottom floor deck, 8-inch-thick
fiberglass batt insulation with a vapor barrier at the top against the warm
side of the structure, and finally, a layer of 1⁄2-inch fire-resistant gympsum
board nailed to special resilient channels attached to the joists.

➤➤➤➤➤ POINTS TO PONDER
1. Lumber should be air- or kiln-dried No. 2 grade or better. It’s
already seasoned, it won’t shrink as much as regular lumber
will, it holds screws and glue better, provides increased thermal
insulating values, holds paint and preservatives better, and is
less likely to be attacked by fungi and insects.
2. Only pressure-treated or exterior grade lumber should be used
for framing members that will be exposed to moisture.
3. Sill plates must be fastened to the foundation in a positive way,
typically with anchor bolts that are partially embedded in the
concrete foundation wall tops.
4. To prevent air, moisture, or insect intrusion through gaps or
cracks which could otherwise exist between the foundation top
and sill plate bottom, a resilient, waterproof layer of sealer
(sometimes of or similar to felt or fiberglass or Styrofoam) is
pushed over the protruding anchor bolts so that it is sandwiched
and tightly squeezed between the foundation and sill plate.
FLOOR FRAMING
5. In good construction, floor joists are placed either 12 or 16
inches on center and are made of planks a minimum of 2 by 10
inches or 2 by 12 inches.
6. Double-thickness floor joists—two planks fastened together—
should be used where extra strength is needed: wherever the
first- or second-floor walls run parallel to the floor joists, for
instance, or at openings around a stairway, near a fireplace
chimney, under cast-iron bathtubs, or at any major change in
joist direction.
7. To stabilize floor joists, bridging or blocking must be used to
help keep the joists properly aligned so the floor decking has a
continuously level base to rest upon.
8. Give careful consideration to house designs that call for floor
extensions that protrude outside the basic perimeter of the
walls. They might be needed for porches, second-story overhangs, decks, or bay windows. A sizeable protrusion could
require supports outside of the foundation wall or even an
actual adjustment to the foundation.
9. If you live in termite country, consult a professional exterminator
and arrange whatever precautionary work that’s needed. Construction precautions may include filling in the top two courses
of foundation blocks with concrete and installing a noncorrosive
metal termite shield that extends at least 2 inches out and 2
inches down at a 45-degree angle from the foundation wall.
10. Insulation from noise can be an important feature in a home,
especially in single-story dwellings with basement recreation
rooms.

CHAPTER
8
Wall Framing
T
he wall frame is the next logical part of the house to erect after the
first-floor decking is attached to the foundation. Wall framing
performs three basic tasks. First, it supports the home’s upper floors,
ceilings, and roof. Second, it acts as a base on which outside and
inside coverings can be fastened. Third, it provides space for and
conceals essential wiring, pipes, heating ducts, and insulation. In its
most general sense, wall framing also includes room partitions that are
constructed within the outer perimeter of a dwelling.
TYPES OF WALL FRAMING
There are four types of wall framing worth noting: platform, balloon, post and beam, and pole.
Platform Framing
In platform framing, each floor is built separately, one on top of the
other, with the first floor providing a work platform for the second
level, and so on (Fig. 8.1).
Balloon Framing
In balloon framing, the studs or vertical members of the exterior
walls are continuous from the sill plate of the first floor to the top plate

of the second floor. These long studs are
more expensive than the studs used to
frame single-floor levels, and the labor to
erect the longer studs, due to scaffolding
required, is higher (Fig. 8.2).
FIGURE 8.3
Post and beam framing.
Post and Beam Framing
Post and beam wall framing uses long, thick structural members—
often rough-hewn posts and beams. There are fewer framing pieces
required, and those pieces must span lengthy open spaces. Wooden
planks are used for the floors and roof. In fact, they supply the sole
support over long spans in both, being nailed at their ends to wood
beams. Consequently, post and beam framing doesn’t employ joists for
the floors or ceiling. This type of framing is very popular where
exposed beams and beamed wide-open ceilings fit the particular style
or decor of a home (Fig. 8.3).
Pole Framing
In certain situations this uncommon type of framing has an advantage
over studded wall framing in that long wooden poles, if properly pres-

FIGURE 8.4

191
sure treated, can be embedded deep into the ground to provide a total
bracing effect for the walls against the force of strong winds (Fig. 8.4).
STUDDED WALLS
By far, studded walls support most of the floors, ceilings, and roofs
of modern dwellings. This conventional wall framing consists of a
combination of header, studding, and top plate, which should be doubled (Fig. 8.5).
Exterior Studded Walls
The header for the exterior walls runs on and along the top outer
edge of the sill plate and against the perimeter of the first floor joists
and decking. It should possess greater width than individual wall
studs—usually 2- by 10-inches. Specify the quality of all framing lumber to be KD No. 2 BTR SPF or better grade and a species appropriate
for the span, spacing, and load.
Many contractors will suggest the use of
2- by 4-inch studs in the wall framing. Don’t
be swayed by a builder who advocates such
construction. By going with 2- by 6-inch
studded walls, you’ll end up with stronger
walls that will accommodate thicker blankets of insulation—that will, in turn, yield
greater energy efficiency for a proportionally small increase in construction costs.
Have the wall studs spaced 16 inches
on center to provide a sturdy base for exterior and interior wall coverings to be
attached to. Use a double-width top plate
of 2 by 6-inch lumber to hold the top of the
walls together.
Interior Studded Walls, or
Partitions
Conventional interior wall framing consists, as does the exterior wall, of a combination of sole plate, studding, and top plate
FIGURE 8.5
A studded wall frame, with double top plate.
192
HOW TO BUILD IT
(often doubled) to receive the weight of the ceiling joists. The sole plate
generally runs across the floor decking, parallel or perpendicular to the
floor joists, depending on the direction of the partition. The ceiling joists
are typically positioned directly over the supporting studs applicable.
The partition tops should also be capped with two pieces of 2-inch
thick boards, which are lapped or tied into exterior walls wherever
they intersect.
If your house is a one and one-half-story or two-story design, it will
require the installation of one or more load-bearing partitions before
the structural framing work is completed. Later, interior partitioning
consists of fitting the other various room and intersecting partitions to
load-bearing partitions and exterior walls.
In a conventionally framed two-story home, the load-bearing firstfloor partition should be placed directly over the main longitudinal
support beam or girder that rests on the foundation walls. Load-bearing partitions on a second floor should likewise be positioned over
corresponding members on the first floor,
so weight will bear down upon the main
girder(s) beneath the first floor.
Remember, due to their size and shape,
combination bathtub/shower units must
be installed during the wall partition and
framing activity (Fig. 8.6). Select the models and colors well in advance so they can
be ordered and received in time for the
plumbers to erect them when the framing
crew is ready.
Corners
The corners of wall frames need extra
support because they must provide stability to both intersecting walls. They involve
the assembly of “posts” with insulation,
and corner bracing for strength, also with
insulation (Fig. 8.7).
Posts

The posts are block assemblies of 2- by

ners of wall frames and where interior partitions abut an outer perimeter wall. They should be constructed to provide a good nailing surface
for exterior and interior wall coverings, and because they’re hollow,
they must be filled with fiberglass or other insulation so that heat is
not wasted through the thermal break they’d otherwise create (Fig.
8.8). The insides of posts must be insulated as they’re being put
together. It can’t be done later, when the posts are covered over.
Corner Bracing
If plywood at least 1⁄2-inch thick is used as the outer sheathing on
the wall frame corners, depending on where you live (i.e., a location
where strong winds and storms are common), other bracing may not be
necessary (Fig. 8.9). But if the outer sheathing is a material that’s not
very strong, such as particle board, additional bracing will be needed.
An effective corner brace to specify is the diagonal support that’s “let
into” or inset into the outer corner studs (Fig. 8.10). This type of brac-
193
194
HOW TO BUILD IT

ing is achieved with either 1- by 4-inch or 1- by 6-inch boards that fit
snugly in notches cut at appropriate angles at the proper height of each
wall stud crossed. The inset boards on both sides of a corner rise to
meet each other in the shape of a triangle (Figs. 8.11 and 8.12).
OPENINGS IN WALL FRAMING
Remember that it’s the outer walls of a home that protect the occupants from winds and inclement weather, noise, and unsightly views.
WALL FRAMING
195

F I G U R E 8 .1 0
Diagonal corner bracing.
Openings should be strategically placed as
well as being soundly framed. Here are
some pointers to consider when planning
the openings in your wall frames:
1. It’s important to know far in advance of
the wall framing, the size, type, and
brand of each window and door you
want so the rough opening dimensions
can be secured from the manufacturers
and passed along to the carpenters who
will be erecting the wall framing.
2. In good construction, board cuts and
joints should be accurate and tight at
the junction of the roof rafters and the
ridge board, at the headers of windows
and doors, and at all intersections. Cuts
and joints that result in large, obvious
gaps create weaknesses in the framing
that you should not accept.
3. Wherever an interior door or window
will be hung, there must be double

studding around the opening to make up for the support studs that
would otherwise go in place of the door or window opening. Double studding also presents a needed place to nail door and window
trim. A double horizontal lintel or header is used to support short
studs that reinforce the top plate of the wall above the opening
(Figs. 8.13 and 8.14). The planks for the headers should be 2 by 10s.
WALL FRAMING
197
4. If any of your exterior walls will have
brick veneer coverings, you’ll need
steel lintels to support the brick veneer
over the tops of window and door openings (Fig. 8.15).
5. If you desire, blocking can be installed
to the right and left of each window
between the studs to provide a solid
backing to which curtain rods can be
mounted. Anywhere you plan to hang
heavy or often-used objects such as
large pictures, trophies, or hanging
bookcases,
arrange
for
blocking
between the studs to take the weight.
Keep this in mind in the bathroom, for
fastening towel racks, soap dishes, and
toothbrush holders to the wall.

the storage portion of the cabinet is
recessed into a wall, additional framing
must be installed to accept them. Select
the cabinets well in advance so you’ll
have the correct dimensions of the rough
openings to give to the framing crew.
7. Make sure the framing crew remembers
to install nailers to which drywall or
plaster lathing can be attached, especially in odd corners and spaces where
regular framing isn’t used.
VENTILATION
F I G U R E 8 .1 5
Masonry steel lintel reinforcement over window.
Plan the openings—especially window
openings—for cross ventilation as far as
possible. Good airflow occurs when the air
inlets and outlets are approximately the
same size. A better airflow results from a
larger outlet than inlet.
SHEATHING
One of the last operations of the wall
framing is the installation of the exterior
sheathing that’s attached to the wall studs.
Six materials are typically used, mostly in
4- by 8-foot sheets: CDX plywood, particleboard, fiberboard insulating sheathing,
exterior gypsum board (if you plan to
stucco), rigid foam insulating sheathing,
and Styrofoam insulating sheathing (Figs.
8.16, 8.17, and 8.18).
Exterior sheathing performs three
functions:
F I G U R E 8 .1 6
Plywood sheating construction.
1. It braces the structure. Plywood is the
strongest, most rigid of the six, followed
WALL FRAMING
199
by particleboard. If plywood is used, at
least on the corners, it may eliminate
the need for diagonal bracing. Diagonal
boards with plywood corners will
provide superior structural bracing.
For best results the sheathings
should be applied vertically in 4- by 8foot or longer sheets with edge and center nailing.
2. It provides insulation. If insulation, not
strength, is the main concern, rigid
foam and Styrofoam board are the winners here. They can be purchased with
tongue-and-groove edges to provide a
tight fit to reduce air infiltration.
3. Sheathing provides a weathertight base
for the exterior siding. Plywood and
particleboard sheathings are a strong
base for exterior siding. Make sure the
sheathing you choose will provide the
needed base for the exterior siding you
have selected. Be aware that there are
two types of plywood: exterior and
interior. Definitely, only exterior-grade
plywood should be used for the outside
of a house. Exterior CDX plywood is
made with high-quality veneers and is
bonded with water-proof glue. It offers
the best durability and its glue won’t
weaken with age or with long exposure
to foul weather.
Last, with rigid foam or Styrofoam
sheathing, review with the manufacturer
and your contractor where an additional
vapor barrier may be needed. Besides a
vapor barrier applied to the inside of wall
studs to prevent movement of moisture

Styrofoam or fiberboard.

from living areas into insulation, a vapor barrier may also be needed
on the outside of wall studs. If where you live rigid foam or Styrofoam
traps any moisture inside an exterior wall, it will condense as it
reaches its dewpoint and create water. The water will soak the insulation and rot the sill plates over time.
NAILS
As minor as they might seem, nails are what hold much of a house
together. Only galvanized nails should be used on exposed materials,
both inside and out. Unless the house is roofed over immediately, a
sudden downpour could cause regular steel nails to rust and streak the
surfaces in just one night.
If your walls will have studs with 24-inch o.c. (on center) placements instead of 16-inch o.c. as recommended, nailers will have to be
installed so drywall or plaster lathing can be securely attached. Nailers are small 2- by 4-inch or 2- by 6-inch blocks attached perpendicular to the studs, in between pairs of studs. The nailers will also give
extra support and stiffness to the walls and will act as a fireblock to
discourage flames from spreading throughout a wall.
It’s a good idea to specify that exterior wall sheathing be applied by
hand nailing only. Some of the more fragile sheathings such as
polyurethane board can be easily torn and damaged by power nailing
equipment.
For optimum efficiency, nails should be spaced 6 inches on center
(o.c.).
ENERGY
Energy is of great interest no matter which part of a house is being discussed. But here, with the exterior walls, insulation takes on a special
importance. Naturally, you want to reduce the consumption of energy for
heating and cooling and to increase the level of comfort in the home by
muffling the effects of the elements. That’s another reason why openings
should be carefully planned to prevent unwanted heat loss or heat gain
and to allow for natural ventilation and heat gain when desired.
The major obstacles to well-insulated, sealed walls are doors, windows, and electrical outlets. Again, eliminating as many potential
WALL FRAMING
201
problems as possible in the design stages
is the first and most logical step. Place
wall switches and outlets on interior walls
when possible, and use as few windows,
glass sliders, and doors as practical. Have
reasons for everything that goes into the
exterior walls. When you can, incorporate
features that must be inset into a wall,
within interior walls, where the interruption of insulation is not a factor.
Because wall insulation is so important, the use of 2- by 6-inch studs is
stressed over and over. Old-fashioned 2 by
4 studs were fine in their day, when energy
was inexpensive, but only 31⁄2 inches of
fiberglass batt or blanket insulation will fit
into such walls. With 2 by 6 studs, 51⁄2
inches of the same kind of insulation can
be laid (Fig. 8.19). That makes a big difference in energy use.
SOUND INSULATION
There are two ways to arrange effective
sound insulation for interior walls. The
first employs staggered 2- by 4-inch studs
erected on a 2- by 6-inch plate. The studs
should be positioned 16 inches o.c.

Because the studs are staggered, this technique eliminates the touching of drywall or

plaster on both sides of the wall by any single stud, thus reducing the wall sound transmission capabilities. The
air voids between the studs are “woven” with 31⁄2-inch fiberglass blanket or batt insulation, which will further deaden noise transmission.
In the second procedure, interior walls are constructed with 2- by
6-inch studs and 51⁄2-inch or 6-inch batt or blanket insulation. The
additional wall thickness makes up for sound transmission deficiencies.

HOW TO BUILD IT
VAPOR BARRIERS
In addition to being insulated, living areas should also be sealed
with a moisture-proof layer or vapor barrier that’s applied to the inside
of the wall studs to prevent the movement of moisture from the living
areas into the insulation. Insulation will lose some of its thermal qualities if it becomes damp or wet, and if the moisture within the living
spaces is retained within the house, the occupants will still feel comfortable with less heat, due to the inside humidity. Consult local building codes for guidance on specific vapor barrier requirements.
Depending on your climate, whether it’s hot, humid, or dry, vapor barrier needs vary.
There are several methods for applying a vapor barrier to exterior
walls: install insulating batts or blankets faced with vapor barrier
backings such as treated Kraft paper or aluminum foil. The vapor barrier should always be placed closest to the living area that’s heated. If
unfaced batts or blankets are used, a vapor barrier or polyethylene film
not less than 3 mils thick (or an equivalent) should be applied.
If you elect loose blown insulation, establish a vapor barrier by stapling or nailing polyethylene sheet material to the interior of the wall
studs. You can also install aluminum foil–backed drywall before the
insulation is blown between the studding.
BEFORE THE WALLS ARE CLOSED
Before the walls are closed up, the following items should be completed, if applicable:
■
Sink drains
■ Vents
■ Water supply for sinks
■ Cold water for toilets
■ Water for showers and tubs
■ Hot water for a dishwasher
■ Hot and cold water for a clothes washer
■ Gas lines

INSPECTION
WALL FRAMING
After the wall framing is complete, check
the following:
■
Vertical walls are plumb.
■ Opposite walls of rooms are parallel.
■ Horizontal members (joists, headers, and subfloors) are level.
■ Exterior sheathing is not damaged
or punctured.
■ Plumbing installed
➤➤➤➤➤ POINTS TO PONDER
1. Again, if you’re using wood, use only air- or kiln-dried No. 2
grade or better framing lumber. You don’t need the warping and
shrinking that could result from unseasoned lumber.
2. Don’t be swayed by a builder who suggests the use of 2- by 4inch wood studs in the wall framing to save a few dollars. By
using 2- by 6-inch studded walls, you’ll end up with stronger
walls that will accommodate thicker blankets of insulation.
3. Conventional wood studding should be spaced 16 inches on
center to provide a sturdy base to which exterior and interior
wall coverings may be attached.
4. Use double-width or double-thick top plates of 2- by 6-inch
lumber to hold the top of the walls together.
5. In a conventionally framed two-story home, load-bearing firstfloor partition(s) should be placed directly over the main longitudinal support beam(s) or girder(s) that rest on the foundation.
6. Remember, due to their size and shape, combination bathtub/
shower units must be installed during the wall partition and
framing activity or you won’t be able to simply carry them into
place later—they’re too big.
7. Corners of wall frames need extra support because they must
provide stability to both intersecting walls.
204
HOW TO BUILD IT
8. In addition to being insulated, living areas should also be
sealed with a moisture-proof layer or vapor barrier that’s
applied to the inside of the wall studs to prevent the movement
of moisture from the living areas into the insulation.
9. Sound insulation is important for establishing privacy between
bedrooms, bathrooms, and other living areas.
10. While wall framing is still exposed or open, make sure as much
of the plumbing, electric, communications, doorbells, security
alarm systems, certain types of insulation, central vacuum systems, heating and air-conditioning components, plus various
vents, drains, built-ins, window and door openings, and other
applicable items are completed.
CHAPTER

Roof Framing
T
here’s no getting out from under it: the roof of a house is often all
there is between you and the sky. And as such, the roof will protect
you from such inconveniences as snow, sleet, hail, rain, sunrays,
wind, dust and dirt, acid rain, insects and animals, moonlight, and
noise. It will, when constructed and insulated properly, keep cool air
in the house during summer, and warm air outside. Then conversely,
during winter, the roof keeps cold air at bay and warm air inside.
The typical roof also serves, however infrequently, as a platform for
contractors to walk on when they’re performing maintenance and
repairs—to renew the flashing on a chimney, for instance, or to dislodge a stubborn bird nest from a false flue.
A roof must be securely fastened to the rest of the house, not merely
“tacked onto” the upper level. It has to be able to resist updrafts of
wind that would otherwise yank a roof right off.
The roof and ceiling frame of a home’s upper level needs to be
sturdy enough to support whatever covering or options are planned,
including heavy tiles or slates, solar panels, and skylights. At the same
time, however, it should be noted that any irregularities or impediments to simple rooflines provide opportunities for water or moisture
to seep through the roofing. This includes chimneys, vents, roof lights,
and anywhere the roof has a valley or dormer where one roofline intersects another.

206
HOW TO BUILD IT
Other practical considerations to be made with the roof frame are
the size and shape of the area between the upper level’s ceiling and the
rooftop, commonly known as the attic space. In certain types of
houses, this space can be constructed in a variety of ways. It tends to
follow patterns dictated by the shape of the rest of the house, tempered
by basic aesthetics. Although it should be in correct proportion to the
surrounding architectural components, certain decisions must be
made regarding roof pitch, materials, and construction techniques.
The roof overhang—the part of the roof that protrudes beyond the
exterior walls—protects the exterior sheathing or siding, windows,
and doors from the elements, especially rain and sun. A wide overhang will block the sun on summer days when the sun rises high overhead, then will let the sun rays enter during winter, when the sun
travels a much lower route in the sky.
ROOF STYLES
Six styles of roofs account for the lion’s share of roofs, old and new:
gable, gambrel, hip, mansard, flat, and single-pitch or shed. The first
three are the most widely used (Fig. 9.1).
Keep in mind that the following styles are not restrictive of each
other. A single dwelling can and will often have a combination of several roof styles.
The Gable Roof
The gable roof is the single most popular roof style built today. It
consists of two usually equal-sloped roof planes that meet at a topmost
ridge. In fact, it’s the ridgeline running the entire length of the house,
or at least on the parts of the house having that style of roof, that most
characterizes the gable style. The gable also means the upper triangular area formed on each end of such a roof. Gable or shed dormers are
frequently added to plain gable roofs to break monotonous lines or for
the practical purpose of providing natural light, air, and additional
space to make an attic area more useful.
The Gambrel Roof
In general, the gambrel roof is a gable roof having two separate roof
slopes on each side of the topmost ridge, the flatter or least-sloped of

207
208
HOW TO BUILD IT
the two being above the level of any dormer windows. An advantage
this roof has over the gable roof is that it increases the usable attic
space, and when dormer windows are installed, it’s almost equivalent
to having a second story.
The Hip Roof
With the hip roof, the ridge does not run the full length of the
house. Instead, hip rafters extend up diagonally from each corner to
meet the ends of the ridge. Essentially, the sides or slopes of this roof
angle up in four planes from the outside walls. It’s an exceptionally
strong roof design.
Although by far the majority of houses built today have one of the
above three roof styles, there are an equal number of lesser-used styles
that should also be mentioned.
The Mansard Roof
The mansard is a variation or modification of the gambrel roof. It is
also referred to as a hip version of the gambrel. Its advantages lie in the
space added to the attic and in the additional strength of its construction.
The Flat Roof
Not often used in typical residential construction, the flat roof frequently employs the use of rubber roofing materials covered by fine
gravel. Naturally, such a roof would have to be constructed extremely
strong for any building located in a climate expecting substantial
snowfalls.
The Single-Pitch or Shed Roof
This simple style features a single roof surface or plane that’s usually gently sloped in a single direction. It’s not a bad roof, but its
appearance is rather dull and uninspiring.
ROOF PITCH
When describing a roof’s configuration, “pitch” is the measure of
its steepness or the degree of slope the roof or part of the roof has. It’s
expressed in two corresponding numbers: a value of rise per a value of
run (Fig. 9.2). “Rise” means just what it says—a vertical distance.
ROOF FRAMING
“Run” addresses the horizontal travel it
takes to reach a given rise. A 4–12 pitch
means there are 4 units or measures of rise
for each 12 units or measures of run (Fig.
9.3). It can as easily be expressed with
inches or feet. Whatever measures are
used, the ratio remains constant. Generally, when it comes to roof pitch, builders
tend to do their thinking in inches. A very
low-pitched roof will have a substantially
smaller rise than run: 1–12 or 2–12, for
example. Medium-sloped roofs range up
to about 6–12—about the steepest slope
that a novice can comfortably walk around Determining roof pitch or slope.
on. A roof having a 45-degree angle is considered steep, having a pitch of 12–12.
The pitch of a house roof is influenced by a variety of factors,
including expected snowfall, the heaviness or lightness of construction materials, how much storage or living space you want beneath the
roof, how much insulation is planned, and of course, how the house
should look so it’s architecturally balanced. Different climate conditions and different house types will call for different roof pitches. Here
are the main characteristics of a low-pitched roof:
1. It will shed water well in warm climates, and will, if built soundly,
retain snow for added insulation in colder climates.
2. The area directly under roof will consistently be a wider, more
open space, providing extra room with pleasantly sloped ceilings.
FIGURE 9.3
A pitch of 4–12.
209
FIGURE 9.2
210
HOW TO BUILD IT
3. The low pitch will make both interior and exterior maintenance
safer and less expensive.
4. Since its initial construction requires less material due to its minimal
surface area, it’s also less costly to build than a steeply pitched roof.
To balance out our roof picture, here are some characteristics of a
steeply pitched roof, from 6–12 to 12–12 and above:
1. A steeply pitched roof sheds just about everything in a hurry. Rain
races off its surface, and snow is less likely to accumulate there. A
steeply pitched roof rarely leaks. It doesn’t give the moisture a
chance to penetrate.
2. Although certain individuals can benefit by lofty storage spaces
provided within a steeply pitched roof, care must be taken to avoid
ending up with inaccessible, unpleasant attic rooms. Let no one
sway you into believing that every inch of an attic constructed
beneath steeply sloped roof planes can be gainfully employed.
3. A steep pitch makes maintenance and repairs tasks for professionals, especially when the exterior must be accessed. That means
inconvenience and high expenses for both.
4. Since more surface area is involved, a steeply pitched roof requires
more materials at an initially larger cost outlay.
5. Steeply pitched roofs are good for placing solar collectors on in
cold and warm climate locations.
Keep in mind that the pitch of your roof might limit or even dictate
what roofing materials you can use. Wood and asphalt shingles, wood
shakes, and tile or slate can require a pitch of 4–12 or steeper. Roofs
sloped less than 4–12 are uncommon, and might need to be covered
with an industrial-type flat roof of rubber or tar and fine gravel.
BUILDING METHODS
There are two common methods of constructing roofs:
■
The stick-built system uses individually erected rafters, ridge
boards, ceiling joists, and collar beams assembled on the job.
ROOF FRAMING
■
211
The prefabricated truss system is a newer method in which
trusses are made to your roof’s specifications by a fabricating
company that specializes in this work.
Stick-Built Roofs
Figure 9.4 shows an example of a stick-built roof.
CEILING JOISTS
When all exterior and interior walls are framed, plumbed, and
nailed, and after the top plate has been fastened in place, the ceiling
joists go up to tie the walls together and to form a structural base for
the erection of the roof. In most cases, these joists must span the width
of the house, one overlapping with another, supported by a load-bearing collar beam toward the center of the house. The size of lumber to
FIGURE 9.4

212
HOW TO BUILD IT
use for joists is determined by the distance to span, the type of wood
used, and the load that will have to be supported above. The dimensions of the lumber used for ceiling joists should be specified in the
plans. Do not settle for anything less than 2- by 6-inch planks.
In a two-story home, the ceiling joists at the second level become
floor joists for the attic, and it’s reasonable to assure they must be as
sturdy as those used below and constructed in a similar fashion.
The spacing of the ceiling joists may vary, but, as with studs, 16
inches o.c. is considered standard good construction. The doubled top
plate of the wall frame supplies sufficient strength. It makes sense to
locate joists over the wall stud positions (Figs. 9.5 and 9.6). Install
wood blocking between ceiling joists where bracing is needed for ceiling lights and fans.
Ceiling joists serve several purposes: they resist the outward thrust
imposed upon the walls by the roof rafters, they provide nailing surfaces
for the ceiling and the upstairs or attic flooring, they support any weight
placed on the upper floor. Because of their place in the framing scheme,
joists must be securely nailed to the top plate of every wall that their ends
rest on and to every load-bearing partition wall that they cross or join on.
Note that ceiling joists are not used with houses having truss framing. The bottoms of the trusses, normally constructed of 2 by 4s or 2 by
6s, become the ceiling joists.
RAFTERS
Rafters are wood planks or boards that span the distances from the
top of the exterior walls to the roof ridgeline or peak to form the skeletal structure that the roof deck is fastened to. The size of the rafters

varies with the distance they must span and the steepness or pitch of
the roof. It’s often computed by referring to tables that show the loadbearing capacities and deflection qualities of various woods and
boards. When sizing your rafters, many variables go into selecting the
proper dimensions, such as length of span, spacing of structural members, wood species, lumber grade, plus expected wind forces and
snowfall. Depending on the conditions, your rafters may need to be 2
by 8, 2 by 10, or even larger.
When selecting roof rafter joists ask your builder about using engineered wood I-beam roof rafter joists.
Engineered wood I beams are made with a top and bottom lumber
flange with a grooved center to accommodate a center web (typically
plywood) (Fig. 9.7). Special hangers with blocking are needed to
secure these beams.
Engineered wood I-beam roof rafter joists offer many advantages:
■ Good strength.
■ Excellent clear span on large rooms. Span longer distances than
regular wood.

screwed straight down (not angled as
when trying to hit half a 2 by lumber)
while staying back from the edges.
■ There is more bearing surface for glue and support.
■ Typically lighter than dimensional lumber.
The rafters should be spaced in the same manner as ceiling joists
are erected, then each rafter can be tied or nailed to a companion joist
as well as to the plate.
Advantages
1. Dormer expansions are relatively simple to make with rafter framing. If you think you might want to expand into an attic, it’s a must
to use rafters instead of prefabricated trusses. And if expansion is
likely, then increase the size of your floor joists.
2. The rafter or stick design is also the better choice when adding
dormers because it’s much easier to tailor the roof to accept the
dormer framing.
3. Rafter-built roofs allow you to have cathedral ceilings.
Disadvantages
1. The main disadvantage of rafter roof framing is that load-bearing
interior walls must be relied upon for support.
Truss-Built Roofs
Roof trusses, unlike ceiling joists used with rafters, span the entire
width of a structure (Fig. 9.8). They are triangular with wood interior
ROOF FRAMING
215
FIGURE 9.8
Truss-built construction.
bridging (W-shaped) for strength. Mathematically, the principle that gives
what appear to be flimsy components the strength to span such long distances is the inherent rigidity of the triangle. Trusses simply rest upon and
are fastened to opposite exterior walls. The individual truss units should
be spaced 16 inches o.c. to avoid the risk of a sagging roof deck.
If you are using a truss-built roof, consider the following three
points:
■ While some contractors use 2 by 4 trusses, a 2 by 6 truss provides
a stronger design. A major disadvantage of 2 by 4 trusses is truss
uplift. When the top chords of a 2 by 4 truss are heated in the
summer, they expand slightly causing the bottom chord to bow
up in the middle. The interior ceiling drywall or plasterboard is
attached to these chords and is pulled upward separating corners
and cracking the joints. If 2 by 4 trusses are being used, consider
requesting 2 by 6 bottom chords to help resist bowing.
■ Trusses limit attic space as a result of the cross member sup-
ports. To alleviate the space loss, ask your contractor if “W”
trusses will support the roof load. “W” trusses have the inner
cross member angled to provide more attic space.
■ Make sure wood blocking is installed between trusses where
bracing is needed for ceiling lights and fans.
Advantages
1. Ceiling joists aren’t needed in the attic.
2. Trusses are built using smaller dimensional lumber than is used by
the stick-built rafter system.
216
HOW TO BUILD IT
3. Despite the small lumber, the truss design still provides adequate
strength to a roof.
4. Savings in framing costs can usually be realized due to the reduction of materials and labor involved with truss installation.
5. The greatest advantage of a trussed roof is that it eliminates the
need for load-bearing interior walls. Trusses are engineered to span
entire distances between opposite exterior walls without relying on
intermediate support. Thus, complete design freedom in the planning of interior space is possible.
Disadvantages
1. The diagonal members used to reinforce the truss design greatly
restrict the amount of usable attic space. To many homebuilders it
comes down to the question of free use of living areas versus the
importance of storage space.
THE ROOF DECK
The roof deck is what gets fastened to the exterior of the rafters and
what the finished roofing shingles, shakes, tiles, or other materials are
fastened to (Fig. 9.9). It consists of a structural sheathing and a moisture-resistant underlayment.
Roof Sheathings
Most roof sheathing is done with plywood sheets in thicknesses
suitable to properly strengthen the rafters and to correctly prepare for
whatever roof covering will be used. Here are some construction
points to remember about plywood sheathing:
1. The type of plywood to specify is CDX. This comes with a clear (C)
or smooth side to be seen, and a rough side (D) to be hidden. The X
means it’s all held together with exterior-type glue.
2. The plywood thickness for roof sheathings should be at least 5⁄8
inch, and preferably 3⁄4 inch. Review your local building requirements. The added thickness of 3⁄4 inch gives superior resistance to
high winds and affords better penetration for shingle nails. Plywood roof sheathing should be on 16-inch on center roof framing,
ROOF FRAMING
217
FIGURE 9.9

with metal “H” clips fastened between the edges of the plywood
sheets to reduce the potential of the sheathing to sag and to give
extra support between the framing rafters or trusses.
3. For the greatest overall strength, the 4- by 8-foot or larger sheets of
plywood should be laid crossways to the rafters or trusses—similar
to their use over floor joists—to tie the greatest number of framing
members together as possible with a single sheet.
4. The joints should also be staggered by at least one rafter or truss so
that there is no continuous joint line from a cornice to the roof ridge
board. No adjoining panels should abut over the same rafter or
truss.
218
HOW TO BUILD IT
Roof Underlayments
The second step toward completing a roof is to place a layer of
underlayment or saturated roofing felt paper on top of the plywood
sheathing. The roofing felt should be a 15-pound or 30-pound material, which means that the weight of the amount of felt paper that
would cover 100 square feet in a single ply is 15 or 30 pounds, respectively. The shingle manufacturer may specify which felt to use so the
warranty remains in place.
Roofing paper should be applied with 6-inch end overlaps and
head overlaps along the edges of 3 inches. Many felt papers have white
stripes on them for indicating the correct overlaps, and such stripes
can also be helpful guides for coursing the shingles.
There are three basic reasons that felt paper is placed over the
sheathing before the final roof topping material is laid:
■
It provides additional weather protection for the roof.
■ It’s a resilient padding between the shingles and the wood
sheathing.
■
It keeps the sheathing dry until the final roofing material can be
applied.
It’s a good idea that the roofers try to paper a roof on a mild-weather
day. If the temperatures are too cold, the paper becomes brittle and tears
easily. If the weather is too hot the paper becomes soft, and likewise
tears easily. Of course, building paper must be applied perfectly flat to
avoid bulges on the finished roof. Although numerous roofing underlayments are available, many contractors have been using ice and water
guard underlayments, especially where water and ice plays a role, such
as along valleys, drip edges, dormers, chimneys, and other roof parts.
VENTILATION
When closing a car door from the inside, have you ever experienced pressure on your ears because the car is practically airtight, and
there’s barely any means for the air to escape? Or how about storing
fresh mushrooms in an airtight plastic bag? Any cook knows that to do
so invites spoilage: if air cannot freely circulate around the mushrooms to remove “expired” moisture, then that moisture will quickly
ROOF FRAMING
condense onto the mushrooms and will cause them to deteriorate,
even if they’re kept cold.
The same principle holds true with houses, especially when it comes
to roofs. A house/roof combination that’s too “airtight” is unhealthy.
Moisture that’s given off from a variety of our appliances and fixtures
such as toilets, showers, clothes washers and dryers, dishwashers, cooking surfaces, and even from our own breathing—not to mention periods
of high-humidity weather—becomes an agent that will, if not removed,
rot wood, wreak havoc with insulation, and even go right through to the
underlayment of a roof and affect asphalt or wood shingle roofing materials themselves—all from within. Materials stored in moist environments will also tend to be ruined by mildew over the long haul.
Thus, an airtight, self-contained roof/house combination is not
only undesirable, but is downright dangerous to have. Many old
houses were constructed without vents. Instead, the owners relied
upon large double-hung windows and screens positioned at the gable
ends, opening them for a cross breeze. That worked fine until the windows rotted or “froze” shut and couldn’t be opened or were closed
during rainstorms and times of high humidity. That’s why you’ll find
so many old houses with rotting wood roofs and musty-smelling attics
that are extremely hot in the summer and freezing in the winter.
Hot air accumulates in the attic as heated air rises from the home’s
living areas, while sunrays superheat the roof. Trapped hot air in an
unventilated or improperly ventilated attic will defeat the best efforts
of air conditioning, insulation, and even shade trees to help keep a
home cooler during summer. On the other hand, effective attic ventilation reduces heat buildup, helps keep the living quarters comfortable, cuts cooling costs, extends shingle life by keeping the roof cooler
during hot weather, helps reduce moisture buildup that encourages
mildew growth and rot on the roof’s framing members and sheathing,
and also minimizes the buildup of ice dams on the roof and gutters
during winter.
Nowadays, all good builders realize that attic or roof vents are
necessities, and the builders supply one or a combination of several
vent types to let the house breathe and rid itself of unwanted moisture.
Consider, too, that roof ventilation also allows heat that rises to the
upper reaches of the roof interior to escape, and does the same for dangerous gases or fumes that could collect there in the event of an accident or emergency.
219
220
HOW TO BUILD IT
How much ventilation is needed? Your builder should have a good
feel for that. It can be affected by the direction of prevailing winds, the
amounts of shelter from the sun, or even from the positions of neighboring buildings or parts of the house itself. Some rooflines can channel wind toward a certain part of the roof, while others might hinder
particular airflows from having desired effects. Roof ventilation is
especially important to houses exposed to continuous sunshine and
equipped with air-conditioning.
Proper ventilation helps remove warm, moist air from the attic,
making your home more comfortable and helping to reduce cooling
costs in the summer and prevent ice dams in winter. An effective yearround ventilation system provides continuous airflow through the
attic, with air entering via soffit vents and exiting at ridge, gable, turbine, or roof vents as well as roof fans.
The following are five popular types of vents that can be used on
new houses (Fig. 9.10) along with window and roof fans.
Ridge Vents
Because the ridge line is the highest part of a roof, it offers an efficient location for a ventilator. A ridge vent typically consists of a long
channel or “crack” covered by an upside-down gutterlike vent running
along the roof ridge that permits air to escape from the house and prevents rain from entering.
A ridge vent will vent your entire peak, working with the wind to
siphon moist, hot air out of the attic spaces and protecting your roof
and keeping your house more comfortable.
Ridge vents should be durable and weather-resistant. They typically come in metal or plastic. When choosing yours, make sure it
offers the following qualities:
■ Rain- and snowproof, prevents both from entering
■ Rated to withstand high winds (in excess of 100 mph) and bliz-
zard conditions
■ Bug- and insectproof
■ Resists denting and cracking
■ Warp-proof

These are the triangular slatted arrangements you’ll notice on practically every house that has gable ends. Frequently made of galvanized
metal, gable vents do a good job of getting rid of heat because they are
located close to the roof ridge. Depending on the location of the house,
a cross breeze will sometimes result.
Roof Turbines
F I G U R E 9 .1 2
A roof turbine vent.
Turbine vents help get rid of heat and
moisture. Roof turbines and fans are galvanized or aluminum vent units fastened to a
side of a roof, on one of the slopes, positioned to act like a wind-powered turbine
or fan when the wind blows, and like a
free vent when the air is still (Fig. 9.12).
The turbine vent utilizes a series of specially shaped vanes to catch the wind and
provide the rotary motion to pull hot and
humid air from the attic. They can be electrically powered to assist in removing hot

air during summer, to augment an air-conditioning system so that it doesn’t become
overloaded. Look for a turbine vent with
sturdy rust-free construction (typically
aluminum) that has permanently lubricated upper and lower bearings, rated to
operate from as little as a breeze of 1-mileper-hour through regular winds, and be
able to withstand the strongest winds
expected in your location.

vent out. The quantity used will depend on the size of your roof.
Soffit Vents
Soffit ventilators are similar to gable vents, except they’re positioned at the eave or soffit areas of the roof (Fig. 9.13). Install a continuous pattern of soffit ventilation under the eaves to allow fresh, cooler
air to enter the attic. Fresh air flows in through the soffit openings into
the attic and then stale air is expelled through the gable vents, roof
vents, ridge vents, turbines, or fans.
Make sure your contractor does not block the soffit vent spaces
between rafters just above the exterior walls, where baffles should
be installed to allow air to move past the insulation. Without ventilation baffles, effective airflow up and out the ridge vents may be
hindered.
And finally, because air will be drawn into the soffit vents, the
vents should include a fine screen mesh to prevent insects from entering. Of course, soffit vents should be made of nonrusting materials,
such as aluminum or plastic.
Window Fans
When any or all of the preceding vents do not provide enough air
circulation, an attic window fan might be necessary to draw out hot air
and rid the attic of unwanted moisture. If you plan to install an attic
F I G U R E 9 .1 3

HOW TO BUILD IT
ventilation window fan, make sure the
builder includes large enough gable or
other vents to permit the passage of enough
air so the fan can operate efficiently.
Roof Fans
A roof fan.
Roof fans, also referred to as attic fans,
have traditionally been electric ventilators
that mount on a side of the roof and can
quickly exhaust heat and humidity from
the attic (Fig. 9.14). The fan motor is typiF I G U R E 9 .1 4
cally activated and shut down by a built-in
thermostat that monitors the attic temperature. When the air rises above a set temperature, the fan comes on; when it falls below that temperature, the
fan shuts down. A manual shutdown switch is normally placed in the
hallway to allow turning the fan off. These units continue to be very
popular in homes. They lower the attic temperature, save on air-conditioning, and make a home more comfortable.
Due to the situation—a roof fan is most needed when the sun is
shining during times of hot weather, it’s an ideal candidate for solar
power. An energy-efficient solar fan provides an excellent way to vent
an attic or garage by using the sun’s rays to exhaust heated air (Fig.
9.15). Their energy source is free and plentiful, with no electrical
wiring or complicated controls to attach.
These relatively inexpensive fans operate fastest during the hottest
parts of the day, then at lower speeds during early morning or late afternoon when
inside air is cooler and needs less circulation. Since sunshine access by the roofmounted solar fan is so important, the
units work best when facing south or
southwest.
Consider these points when shopping
for solar fans:
■ Solar fans should be able to be set to

come on at one temperature, and turn
itself off at another, lower temperature.
ROOF FRAMING
■ The fan design should accomplish positive venting by creating
negative air pressure that will draw heated air, including moisture, out from beneath the roof.
■ A baffle system should enable heated air to exhaust but keep
rain and snow from entering.
■ The unit should provide ventilation even later in the day or
night if temperatures within the space remain elevated. This
can be accomplished with a rechargeable backup battery
charged by excess energy generated during the day by the solar
cell. When fully charged, the battery should have the capability
to operate the vent for nearly three days’ worth of dark or cloudy
weather conditions.
■ A heavy-gauge screen should be attached around the top edge of
the inside housing to keep out insects, birds, and other critters.
Chimney Vents
Although they have little to do with attic airflows, chimney vents
also pass through the attic and roof, or are positioned directly adjacent
to them. Especially if it’s a manufactured metal chimney that has a builtin air space, it should be located at least 2 inches away from any nearby
wood frame. The top of a chimney should clear the roof ridge by 3 feet.
INSULATION
Insulation of the attic and roof is a task that must not be taken
lightly. In cold-climate locations, the heat generated by a furnace or
fireplace rises, and it’s the attic insulation that prevents it from escaping. In warm climates, heat from the sun beaming down on the roof
tends to make the rooms that are directly beneath the attic too warm.
Again, it’s the attic and roof insulation that will prevent heat from
passing through the attic floor into the living areas.
Attic and roof insulation is covered in Chapter 20.
➤➤➤➤➤ POINTS TO PONDER
1. The roof overhang—the part of the roof that protrudes beyond
the exterior walls—protects the exterior sheathing or siding,

windows, and doors from the elements, especially rain and
sun.
A wide roof overhang will block the sun on summer days when
the sun rises high overhead, then will let the sun rays enter
during winter, when the sun travels a much lower route in the
sky. This means a wide overhang is usually preferred over a
narrow one.
Simpler roofs, with fewer angles, valleys, and intersections, are
typically less-expensive roofs, due to simplicity of installation.
Stick-built roofing systems use individually erected rafters,
ridge boards, ceiling joists, and collar beams assembled piecemeal on the job site.
Stick-built roofs allow for simpler dormer expansions and
cathedral ceilings.
Prefabricated truss systems employ trusses made to your specification by a fabricating company that specializes in this work.
They’re simpler to erect on site than stick-built systems.
Include a complete ventilation system with soffit vents that
allow outside air to enter and higher-level vents (ridge, gable,
turbine, roof) or fans to provide air an exit.
If an attic is desired, trusses will not work as well as stick-built
roofs because the truss components take up most of the otherwise usable attic space.
An airtight, self-contained roof/house combination is not only
undesirable, but is dangerous to have. Attic and roof vents are
absolute necessities.
Remember that the steeper the roof pitch, the more dangerous
it is to be accessed for maintenance and repairs.
CHAPTER
10
Roof Exterior Finishing
T
he exterior roof covering is an important milestone in the house
construction process because it brings the job’s progress to the point
of being closed in against the weather, or in the terminology of many
builders: under roof.
The reasons for reaching this stage as quickly as possible are to protect the already completed construction from extensive damage due to
rain, snow, and exposure, and to provide cover and enclosure so that
further construction can proceed despite inclement weather.
ROOFING MATERIAL SELECTION
Good reasons exist as to why you should explore the various types
of roofing materials available for your house. Indeed, your selection
may be influenced by the following:
1. The desire for fire protection. At one time, the combustibility of a
house’s roofing material substantially influenced the fire insurance
rate charged. Certainly, if you’re miles away from the nearest hydrant,
you might want to think twice about wood shakes or shingles.
2. The effect that weather elements have in the area you live in. Certain
roofing materials hold up better in certain climates than others will.
227

HOW TO BUILD IT
3. The life expectancy of the roofing. The price of the labor needed to
replace a roof is high. Therefore, it’s important to pick out a roofing
material that will last. Don’t make the mistake of selecting a material that will need replacing in less than 10 years. A quality product
should last for 20 to 30 years of normal use.
4. The type of house and how the house is positioned on the lot. If
large expanses of sloping roof will be visible from the ground, try to
choose a material that will contribute to the overall attractiveness
of the home. Too often an owner will select expensive siding materials only to downgrade the building’s appearance with a cheap
roof. Instead, give careful attention to your roof; use materials that
add color, patterns, or textures as desired.
TYPES OF ROOFING
There are basically six types of roofing that cover about 95 percent
of the residential roofs: asphalt shingles, fiberglass shingles, wood
shingles and shakes, slate shingles, tile shingles, and metal shingles.
Asphalt Shingles
By far, asphalt shingles (Figs. 10.1 and 10.2) are the most common
roofing material in both warm and cold climates. Sometimes they’re
also referred to as composition shingles.
These durable shingles, depending on their weight, have a life
expectancy of 15 to 30 years. They’re made of a heavy paper known as
felt, which is coated with hot liquid asphalt then covered with fine
rock granules.
Asphalt shingles are manufactured in many different colors by
many different companies. These shingles
vary in weight from about 165 pounds per
roofing square (a roofing square equals 100
square feet of roof area) to about 340
pounds per square. The heavier shingles
are more expensive and have greater textures and longer life. They also take more
F I G U R E 1 0 .1
time and effort to put up, and most roofers
will charge a higher rate for applying them.

229
FIGURE 10.2
Asphalt shingle installation.
There are many different kinds of asphalt shingles. The minimum
grades weigh about 165 to 235 pounds per square, the medium grades
run about 235 to 250 pounds per square, and the top grades weigh
above 250 pounds per roofing unit. If a medium- or heavy weight shingle is selected, the house framing will have to be strengthened enough
to support the additional weight. The heavier the shingle, the longer
the life expectancy. A 300-pound or heavier asphalt shingle should
last between 20 to 30 years. Besides being more durable, premium
shingles are offered in better colors, colors that do not fade as quickly
as the less-expensive models do. The 250- to 340-pound shingles are
also less susceptible to wind damage than the lighter shingles because
of their heavier, stiffer construction. But even if you live in a severe
windstorm or hurricane area and decide to use the heavier asphalt
shingles, they should have self-sealing tabs so curling doesn’t result.
Winds can play havoc with asphalt and other shingles. To prevent
such damage from occurring, choose only shingles with self-sealing
tabs, plus opt for the interlocking types having tabs and slots used to
hook each shingle together with the adjacent ones. Consider that light
shingles have a tendency to get blown around in heavy wind.
230
HOW TO BUILD IT
Last, although asphalt shingles are the most popular selection for
roofing materials on new construction, they should be used warily on
roofs having pitches of less than 3–12. With very low slopes, water seepage can occur under the shingles, especially during times of high winds.
Fiberglass Shingles
These shingles are similar in appearance to the asphalt variety, but
are more resistant to fire. Ask your insurance agent about the possibility of reduced
premiums for your homeowner’s policy if
you elect to go with fiberglass shingles. As
with the asphalt type, the heavier fiberglass shingles are the more durable. Stick
with self-sealing or interlocking shingles
for protection against wind and curling.
Along with the asphalt shingles, fiberglass
ones should not be used with a pitch of
less than 3–12 unless a properly installed
underlayment is laid first.
Fiberglass is a popular choice due to its
favorable combination of appearance,
price, and durability.
Wood Shakes and Shingles
FIGURE 10.3
A wood shake and shingle.
Wood shakes and shingles are available in several species of wood, with red
and white cedars the most popular, followed by cypress and redwood (Fig. 10.3).
The term “shingle” means that the wood
has been sawn, whereas “shake” indicates
that the wood has been split. The shake is
usually thicker and has a more rustic
appearance.
Supply and labor costs to install wood
shakes or shingles can be four to five times
that of installing standard asphalt or fiberglass shingles. Homeowners, though, consider wood shakes and shingles a step up
in quality and beauty.
ROOF EXTERIOR FINISHING
“Hand-split” wood shakes and wood shingles have been popular
for quite a while in the western United States, but did not reach the
Midwest and East in appreciable numbers until the late 1960s. Their
increasing popularity is attributed to their textures, deep shadow
tones, longevity, weather resistance, and compatibility with Colonial,
Modern, and Contemporary house styles.
The main drawback to wood shakes and shingles is their flammable nature.
Slate Shingles
Slate is one of the finest roofing materials available, and one of the
most expensive (Fig. 10.4). Certainly it’s one of the most durable shingles you can cover a roof with. But it also can weigh over 3,000 pounds
per square (compared with 165 to 350 pounds for asphalt and fiberglass, and 200 to 450 pounds for wood), so a slate roof frame must be
designed strong enough to support such an ambitious load.
Roofs made of slate shingles can add considerably to the value of a
house. Pieces of slate are available in smooth commercial grades or
rough quarry runs, in different colors and variegated shades depending on where they come from. They make a beautiful roof and, if cut
from a good mineral bed, will last 100 years and more.
It’s unfortunate that slate has been given a bad name from older
homes where tree-damaged roofs or roofs undermined by rotting wood
supports caused by a lack of proper ventilation result in loose and
FIGURE 10.4

231
232
HOW TO BUILD IT
fallen slate roofing. People have heard horror stories about the high costs of repairing
old slate roofs and have unjustly grown
overly wary of the slate shingles.
Tile Shingles
Clay or cement tile shingles are especially popular in the sunbelt areas (Fig.
10.5). They come in all kinds of decorator
shapes and colors and textures. They’re
simple to install but physically taxing
because of their incredible weight—from
800 to 2,600 pounds per square. As with
slate shingles, a tile roof needs to be well
braced to support its own weight. The tiles
are apt to be expensive, especially in areas
where they aren’t frequently used (outside
of warm-climate locations), but they are
durable and have a long life expectancy.
They should be used sparingly for flatsloped roofs, and should generally be
applied where the pitch is steep enough
for water to run down quickly to avoid
water backup and leaking roofs.

FIGURE 10.6
Metal shingles.
Metal Shingles
Metal roofs, especially ones made of
high-quality copper, terne (tin/lead alloy),
or aluminum are very durable (Fig. 10.6).
At the same time, they’re relatively expensive and can be noisy to the point of aggravation in a rainstorm.
Aluminum shingles are lightweight
when compared with other roofing materials (about 40 to 60 pounds per square) and
come in many modern colors, shades, and
styles, mostly in a shake-type texture.
They’ll last a long time if fastened securely
with aluminum nails.
ROOF EXTERIOR FINISHING
ROOFING COLOR
If your roof is a complex one, with many dormers, valleys, and
varying planes, medium to dark roofing shingles will tend to pull it all
together in a nice way.
Check other houses that are already completed in the area or on the
street you’re planning to build. If several or many of them are using
similar colors, it might be wise for you to select something different so
your home doesn’t “blend in” with the rest of them, to break the
monotony.
Be aware that a light-colored roof reflects heat and is more desirable in areas where air-conditioning is the greatest energy user. Whites
and light grays are the most effective shades and when it comes to
keeping roofing and attics cool under strong sun rays. Other colors and
darker shades convert more of the sun’s rays to heat.
In humid locations and places where tree leaves and debris tends to
fall on roofs, algae and mildew growth may be a problem. This can be
seen as dark areas or streaks on light-colored roofs. If your site has
these conditions, select algae-resistant shingles. They have a slight
amount of copper in the surface granules. Copper ions retard the
growth of algae.
If you live in a warm climate and still decide to select a dark-colored roof, make sure you have sufficient ventilation, insulation, and
air cooling to negate the additional warmth absorbed by the shingles.
VENTILATION AND SOFFITS
The roof and attic should be assured of adequate ventilation to
allow for the escape of heat and humidity (Figs. 10.7 and 10.8). All
ventilation units installed on the roof or in gable ends should be
designed to shed rain and snow and not permit any moisture penetration. In addition, the free opening vent areas must be screened to protect against entry by insects, bats, rodents, squirrels, and similar
invaders Soffits, the flat painted surfaces under a roof or overhang,
should be constructed of prepainted or vinyl-coated sheets that are
maintenance free (Fig. 10.9).
They’re available with either a smooth unbroken surface, but also
with perforated or slotted surfaces that will encourage ventilation of
the attic or roof space. You need a steady pattern of perforated soffits
233

FIGURE 10.9

ROOF EXTERIOR FINISHING
to ensure effective air flows for circulation. Eave soffit vents work by
allowing circulation of air through an attic to prevent moisture condensation and its consequential damage to roof structure and insulation. When installing the soffit vents, insulation must not plug the
spaces between the rafters just above exterior walls. To prevent this
from happening, consider the installation of baffles that will allow air
to move past the insulation. Also remember that venting the eaves
alone is insufficient. Because warm air circulates upward, roof or
gable vents mentioned earlier should be used in addition. There must
also be enough free opening areas near the top of the attic to match the
collective opening space of the eave soffits.
Because ventilation is so important, a ventilation system may
include soffit vents with a combination of roof ridge vents, louver
vents, metal dome vents, gable vents, and turbine vents, any combination of which will:
■ Allow outside air to flow naturally upward and out of the attic.
■ Promote a cooler, drier attic.
■ Prevent moisture from becoming trapped within insulation,
structural wood, shingles, and roof deck.
■ Help prevent rotting, mildew, drywall damage, peeling paint,
and warped siding.
■ Provide year-round performance for consistent ventilation, low-
ering the overall energy consumption.
FLASHING
Protecting framing and insulation from rain, snowmelt and moisture is critical. All can cause great amounts of damage and inconvenience. At the very least, uninvited moisture in its many forms can
reduce the insulating value (reducing energy efficiency) and damage
your ceilings and walls.
Flashing is sheet metal or other material used to prevent the leakage or driving in of rainwater and general moisture infiltration at joints
near openings or where different materials or planes meet, such as
around chimneys, vents, roof valleys, and stacks (Figs. 10.10, 10.11,
10.12, and 10.13). If a material projects horizontally from the surface of
the house, as at window and door trims, or at the insulation around a
235
236
HOW TO BUILD IT
foundation, flashing is required. It’s also needed wherever roofs and
walls join, as with a split-level house or a two-story having an attached
garage (Fig. 10.14). Flashing is important at the juncture of a dormer’s
siding with a main roof, to prevent water from leaking through (Fig.
10.15).
Aluminum is the most common flashing material. It’s produced in
long rolls in several widths and is inexpensive, lightweight, and resistant to corrosion except in industrial areas and near the seacoasts. It
has one drawback—a shiny appearance that must be painted. And aluminum does not paint well.
Galvanized steel and terne are also employed as flashing; but they
must also be painted. Stainless steel, zinc alloy, and even lead have all
been used in similar fashion.
An excellent, though expensive, choice for flashing is copper. It
seems to last forever and requires almost no maintenance. One advantage it has is that its corners can be soldered for a watertight connection.
Asphalt roofing material is sometimes used for valley flashing on
roofs, and plumbing stacks are frequently flashed with special neo-

prene plastic collars. Vinyl materials in various colors are also on the
market. Vinyl is an excellent choice and costs substantially less than
copper.
Chimney Flashing
Because the chimney’s exterior can be a frequent source of
unwanted water intrusion, a few words on its flashing will perhaps
save considerable trouble in the future. For sure, water seepage around
the chimney can enter the attic or spaces beneath the roof and ruin the
insulation there, do damage to the roof sheathing and framing, and
eventually ruin the ceiling below. When there is such a leak, the problem is usually with the chimney flashing. The sheet-metal flashing
around the chimney is supposed to keep the intersection between the
chimney and roof watertight.
An effective way to seal a chimney is with two flashing layers: flashing and counter-flashing. The first layer is called step flashing, where
sections of L-shaped sheet metal are “woven” into the surrounding
shingle courses and lapped snug up against the chimney sides.
This flashing is installed in a stair-step fashion starting at the bottom or lower side of the chimney, working toward the upper part, fastened to the roof only, not to the chimney. Next, a small lip of the
counter-flashing metal is embedded in the chimney mortar joints, and
folded down to cover the tops of the step flashing. Then when the roof
moves with winds or from shrinkage, the two pieces of metal flashing
move or slide against each other to prevent bending or damage while
maintaining protection from water. The
corners of this arrangement are especially
vulnerable, and an effective installation
will leave only a small spot that must be
sealed with high-quality caulk.
A special situation occurs when a
chimney is positioned at or near the bottom of a roof slope. In such a case, a
“cricket” or “saddle” should be installed
at the intersection of the chimney’s high
side and the roof to divert and prevent
water from rushing down the roof into or
F I G U R E 1 0 .1 6
against the up-roof part of the chimney
(Fig. 10.16).
A chimney cricket or saddle.
239
240
HOW TO BUILD IT
A cricket also prevents leaves, twigs, and other debris, snow, and
ice from collecting behind the chimney—which can cause rain or
snow melt to back up beneath the shingles and leak through the roof.
If the cricket is large and exposed to view, it should be framed,
sheathed, and finished with the same shingles and flashing used on
the rest of the roof. Smaller crickets unexposed to view, can be covered
with metal, but must still be flashed at all joints with the roof and
chimney.
INSTALLATION
No matter how good a roof’s materials are, the roof won’t be able to
do what it’s supposed to do if the installation is shoddy. Here are some
things to watch out for:
■ The ice and water guard or similar underlayment, which is
needed to protect your roof deck from ice damming and windblown rain, should be flexible, self-adhesive, and waterproof.
■
A 3-inch galvanized metal drip edge eave should be installed
nailed at least 10 inches on center. Roofing ice and water guard
or a similar underlayment should go beneath this drip edge.
■
All roofing felt should have at least a 6-inch vertical overlap.
■
Ice and water guard, a water-resistant underlayment (Fig. 10.2),
provides superior roof deck protection and helps prevent damage caused by freeze/thaw cycles, pooled water, wind-driven
rains, and normal water flow that occurs around roof valleys,
vents, skylights, and chimneys. It should also be installed under
shingled roofing eaves to protect against water backup from ice
dams and hard rains.
■
When anchoring the underlayment and topping materials,
power staple guns are the most economical way to go, but they
don’t do as sturdy a job as nails do. If your roofing is self-sealing
asphalt shingles (shingles with glue underneath each tab that
will stick to the shingle below it when baked in the sun), consider that it takes at least one and preferably two hot summers
for them to “melt” together to form a strong bond. Up until that
time, staples will not provide the holding power of wide-headed
ROOF EXTERIOR FINISHING
nails. High winds are more likely to blow stapled shingles from
a roof.
■
Roofing nails must meet the shingle manufacturer’s specifications to protect the shingle warranty requirements. At the very
least, roofing nails will have very sharp points, flat head diameters, and length long enough for full penetration of the roof
sheathing.
■
All roofing nails should be nailed flush with shingles.
■
When wood shakes and shingles are applied, the manufacturer’s
installation instructions must be followed exactly, especially
regarding spacing and fastening.
■
Because of the high asphalt content in asphalt and fiberglass
shingles, it is recommended that temperatures be over 50°
Fahrenheit when installed, as they are susceptible to cracking in
cold weather.
■
Make sure masonry and metal chimneys, skylights, and other
obstructions are in place before the roofing begins. Otherwise,
the roofers will have to make an extra trip to complete the
remaining shingles and flashing, at extra expense.
■
All materials should conform to or exceed requirements of the
local building code.
WATER DRAINAGE
Gutters and downspouts work together to collect runoff water from
the roof and divert it away from the house so foundation seepage can
be prevented (Figs. 10.17, 10.18, and 10.19). They can divert water
away from foundations, plantings, decorative details, basements, siding, sidewalks, driveways, and roof edges, while increasing the width
of roof overhangs and helping to prevent snow and ice slides during
winter. They’re vital necessities in most cases, but can be troublesome
to maintain—tree leaves, seeds, and twigs tend to collect in them and
clog the downspouts, squirrels and chipmunks use them as freeways
and store winter food in them, plus they can be damaged by ice that
collects and hangs from their not-too-strong edges. Here are some
important points to consider when planning gutters and downspouts:

F I G U R E 1 0 .17
A roof drainage system.
1. The least-expensive gutters to buy are galvanized steel models, but
they have to be painted before they can be secured to the fascia or
rafter ends of a roof.
2. Another inexpensive option is to use unpainted aluminum. It’s
durable enough unless exposed to salt air
near seacoasts or air laden with chemical
contaminants. Even when no pollutants
are present, however, this gutter should be
painted for the sake of appearance.
F I G U R E 1 0 .1 8
Metal gutter shapes.
3. Your other choices of gutter materials
are much better: aluminum with factory baked-on enamel, and aluminum
covered with a thin layer of vinyl.
Vinyl gutters (solid vinyl) are also
available. All three are in the long run
durable, economical, and require little
maintenance. Vinyl tends to be brittle
in very cold weather, but it never
requires refinishing because the color
ROOF EXTERIOR FINISHING
243
is integral to its form. Copper gutters
are also available at substantially
higher prices than the others.
4. Metals used in gutters and downspouts vary in thicknesses; 26-gauge
galvanized steel is quite strong and
common, but 24-gauge is stronger.
5. Cleaning gutters and preventing downspouts from getting clogged can be easily done if you specify removable caps
or screens. Then you can just pop off
the caps or screens when necessary
and flush the small accumulation of
silt from the gutters with a garden hose.
6. Gutters should be mounted on the fascia boards (especially when the fascia
is not made of or coated with vinyl) so
the gutter backs are offset slightly, with
an airspace between the fascia so the
fascia surface will not deteriorate from
lack of ventilation.
F I G U R E 1 0 .1 9
7. Large houses with great expanses of
roof require that both the gutters and
A gutter and downspout arrangement.
the downspouts have sufficient capacity to handle expected volumes of rainwater. While 5-inch gutters are common, 6-inch gutters may be
required to handle roofs having very long spans.
8. A roof plane will collect water during any rainfall, especially if
there is wind. The higher the roof ridge, the more true roof area
there is and the faster water will race into the gutters. If you plan a
steep roof, try to be generous with gutter sizes regardless of the
roof area size.
9. Gutter troughs are to be sloped toward downspouts approximately
1 inch for every 12 lineal feet.
10. Your downspouts may be rectangular or round, and plain or corrugated (Fig. 10.20). In cold-climate locations when there is a
244
HOW TO BUILD IT
possibility of standing water freezing
in the downspouts, the corrugated
type is preferable because it can
expand without damage.
11. Downspouts are to be fastened to the
wall every 5 to 6 vertical feet.
11. The water discharge can flow from
the downspouts into drainpipes that
run to storm sewers or to a natural
runoff area, perhaps to the street or a
storage cistern or rain barrel—as long
as it meets building code requirements and does not run into the foundation or form a swamp on adjacent
ground.

COLUMNS
Depending on the construction of your house, unsupported roof
overhangs can protrude from the house a considerable distance. But
beyond a certain point they must be supported around the outer edges
by columns (Fig. 10.21).
Although wood columns, except in very small sizes, are hollow,
they still have the strength to bear a substantial load. Trouble is,
they’re so intricately made that they cost a fortune.
Factory-painted aluminum columns are the answer. They cost considerably less, are maintenance-free, and because they’re hollow—
made only of thin metal—they can be installed around a
weight-bearing wood or steel post.
➤➤➤➤➤ POINTS TO PONDER
1. When shopping for roofing, pay particular attention to fire
resistance, the severity of weather the roof will face, the roofing’s life expectancy, and the roof’s appearance.
2. It takes about the same time, effort, and cost to put on a lowquality, marginal roof as it does one of the highest quality.
ROOF EXTERIOR FINISHING
FIGURE 10.21
A column.
3. Roofing material should not be skimped on. The roofing market
is competitive; and you’ll usually get what you pay for. It’s
worth doing comprehensive reviews and inspections of a wide
variety of materials and models.
4. Selecting premium roofing materials is almost always a wise
decision. They not only last longer and provide better protection against the elements, they’ll also make the home look considerably more handsome.

Shingles should fit tight around all
stack vents and skylights. Areas
should be well sealed with an
asphalt roofing compound.
Shingles should lie flat with tabs
sealed/glued down.
Shingles should extend over the
edge of the roofing deck by at least
3 inches.
Shingles should match or exceed the
required fire rating stated by local
building codes.
Vents and roof flashing should be
painted the proper color with exterior rustproof paint.
Check vents to make sure they are
not blocked with insulation or other
obstructions.
Make sure adjustable attic and other
vents and louvers work correctly.
Downspouts should be secure so that
a strong wind will not affect them.
5. If your roof is a complex one, with
many dormers, valleys, and various
planes, medium or dark roofing shingles will tend to pull the roof together
in an attractive way.
6. Be aware that light-colored roofs
reflect heat and are more desirable in
areas where air-conditioning is the
greatest energy user.
7. In colder climates, the reverse is true.
Black absorbs heat from the sun, so a
darker color is clearly the more practical choice.
8. The roof and attic must be assured of
adequate ventilation to enable heat
and moisture to escape.
9. Flashing is an important component
of roofs. It belongs where different
construction materials or planes
meet, such as around chimneys,
vents, roof valleys, and stacks, and
when materials project horizontally
almost anywhere from the surface of
the house. Simply put, it prevents
water, air, dust, and other materials
from entering cracks and gaps in the
roof and in the rest of the home’s
outer shell.
10. Be generous with large, quality gutters and downspouts that are appropriately selected to complement the
appearance of both roof and outer
shell.

Exterior Wall Finishing
T
he exterior wall covering is the single most dominant feature of a
home’s outer appearance; its color and texture are the first things
noticed by anyone approaching the house. Good design calls for
simple lines, common sense in the selection of materials, harmonious
textures and colors, plus good proportions and scale. A hash of
materials such as a bit of stone here, some brick over there, with
shingles and clapboards and stucco all mixed above, will give the
impression that the house is desperately trying to trick observers into
liking some detail, and more often than not will ruin a dwelling’s
appearance.
Beyond its cosmetic nature, the exterior wall covering also acts as
the final protective layer between a home’s occupants and the great
outdoors. More specifically, it is this outer “sandwich” layer that,
along with its interior counterpart, envelops whatever insulation is
chosen to help protect family members from temperature extremes,
and minimizes the need to import or purchase additional energy
required for comfort. Attached to the frame or masonry walls can be
wood siding in various forms, brick, stone, stucco, aluminum and
vinyl sidings, shingles of metal, asphalt, or plastic, and many other
lesser-used siding materials.

ALUMINUM AND VINYL SIDINGS
Aluminum and vinyl sidings are available in many different colors
and shades, textures, and forms for both horizontal and vertical installation. When used alone or in combination with each other to cover
exterior wood surfaces, they’ll practically eliminate the need for future
wood refinishing and painting chores. These sidings can also help provide additional thermal and sound insulation when installed over
polystyrene or similar backer boards.
Indeed, recent manufacturing innovations enable many sidings to
have wood-grain finishes or textures that look, and often feel, just like
painted wood, smooth “clear” cedar, cedar shakes, weathered cedar,
teak, or fir, roughsawn barnboard, and other varieties. All feature

sturdy locking mechanisms so that individual panels will resist wind
and weather.
For example, horizontal siding panels generally interlock where they
overlap, as do the panels of double 4-inch clapboard, double 5-inch, and
triple 3-inch, plus double 41⁄2-inch wood-grain shiplap (Fig. 11.1).
Aluminum Siding
Aluminum siding is a low-maintenance exterior wall covering that
won’t rust in the ordinary sense. Its baked-on finish lasts for 20 to 40
years, depending on the grade purchased. Aluminum siding won’t rot,
split, warp, or crack. It’s manufactured in a wide variety of colors and
shades from light pastel tints to whites to deep rich tones, and comes
in numerous textures and finishes—some resembling wood siding.
The difference in price and insulating qualities is small, but if you’re
249
250
HOW TO BUILD IT
planning top-notch construction that calls
for aluminum siding, opt for the thicker
gauge because it’s stiffer and holds up better to abuse. The width of the horizontal
type of aluminum siding is a single panel
of 8 inches, or “double-four” panels that
are essentially single panels, each having a
horizontal crease across the middle so it
resembles two 4-inch-wide lengths of
clapboard (Fig. 11.2). There are also clapboard-like panels with 5-inch exposures,

9-inch exposures, and two beveled edges

beveledge siding.
For vertical applications, aluminum siding is available in many of
the same colors and finishes as the horizontal panels, so the two materials can be mixed and matched on the same dwelling. The vertical
siding comes in 10-, 12-, and 16-inch-wide board and batten strips,
plus in V-groove and other styles.
There are several drawbacks to aluminum siding you should know
about. First, unless reinforced by being installed directly over a stiff polystyrene or Styrofoam backer board material, aluminum siding will dent
when soundly struck by a baseball, rock, or other hard object flung by a
neighbor’s 10-year-old son. Second, the surface color can be scratched
off, exposing the silvery bare aluminum beneath. Third, bare aluminum
exposed to industrial pollutants and seacoast environments can gradually react to the airborne chemicals in a negative way. And fourth, aluminum siding can be expensive. That’s because the cost of aluminum
siding is naturally tied almost directly to the cost of aluminum, which
can fluctuate considerably due to the overall supply and demand. Conditions involving wars, tariffs, or the industrialization of China and other
nations can all have dramatic effects on the price of aluminum.
Vinyl Siding
Vinyl siding is another popular low-maintenance wall covering
that’s manufactured essentially in the same forms as aluminum siding.
As with aluminum siding, vinyl can be backed with a polystyrene or
other board reinforcement both to give the siding a strong base and an

insulating R-value (especially when also backed with several layers of
house wrap). A major advantage to vinyl siding is that the color is
molded throughout the entire thickness of the material, so a scratch
will do little damage (Fig. 11.3).
Neither will vinyl siding dent; it’s resilient nature allows it to
spring back into shape after all but the most violent blows. Look for a
vinyl siding that’s a double thick .088-inch rolled-over nail hem
design that increases wind resistance and stiffens the panel. Such a
design may withstand wind load pressures up to 180 miles per hour
when installed with nails and up to 235 miles per hour with staples.
This siding panel should feature a true .044-inch thickness for outstanding strength and durability. Most modern vinyl sidings have one-
251
252
HOW TO BUILD IT
step panel locking systems for secure
installation and perfect horizontal or vertical alignment. Too, the color goes clear
through the vinyl, so scratches won’t
show, and a special sunshield technology
is often used to protect the surface from
harmful sun ultraviolet rays.
Drawbacks to vinyl are that it’s inclined
to buckle or ripple if not installed exactly
correct, and it’s not as readily adaptable as
aluminum is to cover unusual or unique
exposed wood trim.
No matter which type of aluminum or
vinyl siding is selected, make sure the contractor correctly applies caulking around
the doors, windows, and corners—wherever the siding forms a seam across its
grain or meets with different building
materials (Fig. 11.4). The contractor
should also use aluminum nails for fastening the siding materials to exterior walls.
Aluminum nails won’t rust and form
unsightly streaks.
MASONRY EXTERIOR WALL COVERINGS
F I G U R E 11 . 4
Caulking around a window.
Masonry exterior walls of brick and
stone have always held a certain attraction for individuals who prefer
the beauty, feel, and apparent strength of brick and stone construction.
Masonry also enjoys an intangible prestige value that houses sheathed
with wood, aluminum, or vinyl sidings seem to lack.
It’s true that brick and stone sidings are more expensive than most
other exterior wall coverings, mainly due to installation costs. To use
brick or stone, a contractor must either move exterior walls inward 5
or more inches to allow space for the full masonry veneer so the specified outer wall dimensions can be retained or can keep the load-bearing foundation walls and exterior walls true to their specified
dimensions by installing the brick veneer against the outside of these
EXTERIOR WALL FINISHING
walls (Fig. 11.5). To permit the latter
method, a separate outer foundation must
be constructed to support the brick or
stone walls (Fig. 11.6). In either case, there
must also be a space between the masonry
and interior wall surfaces, and this space
should contain proper insulation and a
vapor barrier (Fig. 11.7).
The first choice (of moving the walls
inward to accommodate the thickness of
bricks or stones) should require no change
in the home’s roof structure, particularly
to the overhang and exterior trim. The second choice (of building out) might, however, require alterations in these areas to
accommodate the wider dimensions of the
outer limits to the exterior walls.

Advantages
1. Brick and stone make beautiful, unique
exterior wall coverings.
2. They hold onto their looks indefinitely,
with little maintenance.
3. Brick and stone houses have historically held their value well and have
enjoyed good resale demand.
4. They’re durable and have a reputation
of permanence.
5. Because of their strength, they don’t
“sway” as much in the wind as woodsided homes and will not develop as
many interior plaster or drywall cracks
and imperfections as in less-rigid nonmasonry dwellings.
6. Their resistance to fire is excellent.
7. They help reduce exterior noise.

Disadvantages
1. They add considerable extra expense to
the purchase price of a house.
2. It’s difficult and expensive to make
modifications to the exterior walls or
additions to a structure. Removal of
part of an old wall is expensive, and
matching up the brick for the new walls
can be difficult.
F I G U R E 11 . 7

3. Brick and stone have low insulating values. Despite popular belief, even the
thickest masonry offers exceptionally
poor insulation properties, which is
why masonry houses seem particularly
cold and are hard to heat. Consequently,
the proper amount of exterior wall insulation must be insisted upon regardless
of the type of brick or stone used.
Brick
F I G U R E 11 . 8
A textured brick.
Brick makes a very attractive exterior, with numerous colors and
textures available. All of one color can be used, or a mottled effect can
be had by using many different shades or colors in the same surface.
The best way to arrive at what you’d like is to take a drive through
neighborhoods that have plenty of brick homes. A few color snapshots
of what most appeals to you can be handed to your contractor, who
will be able to tell you where those bricks
can be purchased or ordered.
It should be noted that most bricks are
manufactured with holes in their centers.
When mortar is applied to the bricks, some
of it fills those holes and provides additional bonding strength when dried. If the
top of any bricks need be exposed, enough
solid bricks without holes should be
ordered along with the others. The same
principle applies to textured bricks where
EXTERIOR WALL FINISHING
255
typically only one side—the exposed side—is textured (Fig. 11.8).
When bricks are needed to have a textured surface exposed on two or
three or four surfaces, special bricks that are textured all around will
have to be ordered. Remember that a brick wall will cover a structure,
but won’t support it. The stud wall provides the support. Instead,
metal anchors tie the brick wall to the frame wall.
Make sure the contract specifies that the masons must finish the job
by cleaning the brick with the brick manufacturer’s cleaning solvent.
Muriatic acid can stain brick.
Stone
Stone also makes an attractive exterior that’s durable and practically maintenance-free. It has most of the advantages and disadvantages of brick.
Stonework is usually more costly than brick. In general, stones cut
with rectangular corners are more commonly used for covering exterior walls. Rubble or fieldstones having irregular shapes and no corners can be employed in a feature wall for dramatic effect to create a
rustic appearance.
Openings in Masonry Exterior Wall Coverings
Due to the weight of brick and stone, door and window openings
require special supports to hold the brick or stone securely in place

above those openings. There are three common ways to provide such
support: with steel lintels, curved brick arches, and flat brick arches.
The steel lintel is the simplest to install (Fig. 11.9). It consists of
“angle iron” of appropriate length that overlaps the top of the door or
window opening on either side, so the weight of the brick or stone

257
above the opening can be transferred to
and distributed throughout the adjacent
masonry structure. The curved brick arch
is constructed of standard size and shape
bricks or stones to span the opening (Fig.
11.10), and the flat brick arch is formed
with specially cut bricks (Fig. 11.11).
WOOD SHINGLES AND SHAKES
Wood shingles and shakes are usually
made of cedar, but can be made of redwood or cypress (Figs. 11.12 and 11.13).
Cedar shingles or shakes are used as sidF I G U R E 11 .1 2

catching rustic appeal to the home and a
“warm” siding that’s naturally resistant to decay and is an excellent
insulation. Cedar has a golden brown color when new, that gradually
darkens with age, and finally weathers into an attractive silver-gray,
depending on the climate (the amount of sunlight and humidity) it’s
located in.
The difference between shingles and shakes is that both sides of
shingles are sawn smooth, while shakes
have at least one rough-textured side created by splitting it from the mother log.
These are the same shingles and shakes
that are also used for roofing.
While cedar, redwood, and cypress
shingles and shakes can be installed in
some climates without being coated with
preservatives, weathering everywhere is
best controlled by applying recommended weatherproofings every five or
six years. Pressure-treated Southern yellow pine is also an acceptable substitute,
when available.

can tell the difference between the best and lower grades by the wood
grain—it should be regular and clear with few or no defects.
Drawbacks to wood shingles and shakes include their cost: they’re
expensive and time-consuming to apply. Unless you opt for shingles
and shakes prefabricated into 8-foot panels, each shingle or shake must
be hand nailed into place, one at a time. They’re also susceptible to fire.
Only nonrusting nails that provide sturdy holding power should be
used to fasten wood shingles and shakes to the walls. Common nails
won’t hold well enough and will rust and streak the siding.
Molded “Cedar” Shingles
Molded shingles that look like wood are available in vinyl,
polypropylene, and other plastic materials. Models include both half-

round shingle panels and “full perfection”
shingle panels. While offering the look of
real wood, these panels are practically free
from splitting, warping, cupping, twisting,
fading, or streaking. They also need no
painting or repetitive surface protection.
The panels are typically about 0.100-inch
thick with ribbed backer components that
add structural stability. These molded
shingles hold up well in rainy, windy, and
coastal climate locations, especially when
backed with reflective building foil (Fig.
11-14).
SOLID WOOD SIDING
Almost any type of wood can be used for
solid plank siding, including such species
as cedar, redwood, fir, cypress, pine,
spruce, and hemlock. Redwood siding in
particular is very durable. It resists
deterioration from the weather and from
insects. Unpainted redwood surfaces will
darken season by season to a deep grayish
brown.
Solid wood siding comes in many
styles for horizontal and vertical applications, including beveled, dropped, and
beaded planks for horizontal sidings, and
V-groove, tongue-and-groove, board-and
batten, and channel vertical sidings (Figs.
11.15, 11.16, and 11.17).
Beveled horizontal wood siding is
probably the most popular of all solid
wood exterior wall coverings because it so
nicely complements most styles of architecture. It consists of long boards, available in varying thicknesses and widths
having beveled edges and tapered to exag-

gerate the deep, long horizontal shadow
lines at the lower edges of the planks that
help provide character to a dwelling’s
appearance. The individual boards are
usually installed over a sheathing and
building paper, nailed through them to the
exterior wall studs. Corners are covered
with either metal corner pieces or wood
corner boards (Figs. 11.18 and 11.19). The
thickness of the corner boards should be at
least 1 inch to provide a substantial caulking base.

that once covered (and still covers) many a
home consists of wood planks of uniform
thicknesses.

weatherproofed with water-repellent treatments, oils, varnishes, preservatives, or
exterior paints and other coatings that will have to be periodically
renewed as needed. A vapor barrier beneath the wood siding is also
required to prevent condensation from within the home from causing
paint to peel and wood to rot.
PLYWOOD SIDING
Plywood siding can be supplied in many varieties of wood and patterns at varying costs (Fig. 11.20). Check with your local suppliers to
see samples. Only exterior types of plywood should be considered—
those having their layers of veneer bonded together with a tough
waterproof glue.
Plywood panels are manufactured in 4-foot widths and 8- to 12-foot
lengths that, due to their size and ease of installation, help hold down
labor costs. If you plan to use plywood siding, match the correct length
panels to the requirements of your home to have as few horizontal
joints as possible, because they’ll detract from the overall appearance
and can be a source of water and moisture leaks if not correctly
installed.

Because of its strength, plywood siding is sometimes applied directly
to the wall studs, without the use of an underlayment sheathing.
HARDBOARD SIDING
Hardboard sidings are manufactured panels consisting mostly of
wood products. They come in more finishes and textures than plywoods, but are not as strong.
On the positive side, factory-made hardboard sidings are free from
natural defects. Their panels are stiffer and less likely to warp or bend.
Both the texture and depth of wood are presented in authentic-looking
wood grains and grooves. The better hardboard or wood fiber sidings
are over 50 percent denser than real wood planking and won’t crack,
split, check, or delaminate. They can also be purchased primed—
ready for custom finishing in multiple lap sheets that are easy to
install without having to nail narrow individual boards.
EXTERIOR WALL FINISHING
Remember that even factory-finished hardboard sidings will probably have to be refinished eventually.
STUCCO
Stucco is that plasterlike material so popular with English Tudor
construction. It’s an excellent exterior finish, having a long life span
and needing very little maintenance. It’s really a version of Portland
cement that’s troweled on like plaster to either masonry or frame
walls, with no seams or joints. It’s usually made in white, but can be
colored with any paint manufactured for application over masonry.
There’s also a wide selection of pigments available that can be added
to the stucco mix. If deeper hues are desired, the stucco can be painted
in the same fashion as concrete block.
Stucco can be applied as a finish coat to both existing houses and
new construction. It can be finished to give a number of interesting
textures to conform with traditional or modern architectural styling.
Three coats with a total thickness of about 3⁄4 inch are generally recommended. When stucco is applied over the sheathing of a woodframed house, a layer of stucco wrap can be placed over the sheathing.
Stucco wrap is a type of engineered construction fabric or membrane
(also see house wrap, in the section on Vapor Barriers). Stucco wrap
creates a drainage path for water and moisture to escape. It will take
water and moisture that may enter the walls from the interior spaces
and around windows, doors and other joints, and channel it outside. It
thus helps prevent water and moisture from harming the sheathing,
framing and insulation—which can cause expansion and contraction,
leading to stucco fractures and cracking.
Stucco wrap is also good at managing the hydration process of the
stucco material during the curing. The scratch coat will not absorb water
from the other stucco coats because, again, the stucco wrap channels the
water and moisture toward the outside. Because the scratch coat will
not absorb extra water, it won’t expand and contract much during curing. The result is a dramatic reduction of cracking in the scratch coat.
This helps create a strong, stable stucco, with each layer drying at a similar rate, front to back. A white stucco wrap is often preferred because it
won’t absorb much heat from the sun, and the cooler surface further
extends the stucco drying time, so cracking is even less likely. Less
stucco cracks makes a more solid energy efficient exterior wall.
263
264
HOW TO BUILD IT
Next comes the application of metal lathing nailed to the exterior
wall. The lathing should be self-furring or should be applied with selffurring nails. The most important point in the application of the stucco
is that the scratch or first coat of material must be pushed through the
metal lathing and behind it to form a solid layer between the lathing
and studs or sheathing.
Where stucco is applied over large uninterrupted areas, control
joints should be installed to permit expansion and contraction of the
stucco material. Without these control joints the stucco will crack. As
a general guide, control joints are planned for at least every 3 feet of
travel.
The second coat is applied over the scratch coat (the first coat) after
allowing sufficient time for the first coat to dry. And finally, after the
second coat has dried, the third and finishing layer is applied with
whatever pattern you have selected—smooth, stippled, swirled, or
other (Fig. 11.21).
When applying stucco over masonry, the finish coat can be troweled directly to the block or concrete.
Make sure exterior outlets and fixtures
aren’t accidentally covered, and ask about
the stucco warranty. Strong stucco will
better withstand building movement,
wind pressure, and other stresses.
VAPOR AND AIR-INFILTRATION BARRIERS
F I G U R E 11 . 2 1
Stucco application.
It was apparent decades ago, since the
1950s, that builders needed to protect
their houses from the harmful effects of
unwanted air drafts and moisture. Back
then, they used tar-impregnated paper and
similar building papers and sealing materials.
The living areas between the exterior
walls should be sealed with appropriate
material applied to the inside of the walls
to prevent the movement of unwanted air
and moisture from the outside in, and also
EXTERIOR WALL FINISHING
from the inside living areas into the exterior wall insulation and outer wall coverings (Fig. 11.22).
To reinforce why vapor and air-infiltration barriers are needed, it’s been estimated that the typical home can have
close to a half mile of undesirable cracks
and crevices in its outer shell that can let
out warm air during winter, and cooled air
during summer.
In addition, unwanted moisture that
enters walls can lead to mold, mildew, and
rot. Wall moisture originating from within
a building can sometimes be more damaging than outside moisture penetration.
Daily activities within a household
such as showering, cooking, washing
clothes and dishes, and even breathing—
produce moisture vapor that needs to

escape. Again, without proper vapor barriers, as the temperature increases within a A vapor barrier view.
home, inside water vapor is transmitted
into walls, where it condenses. This condensation results in a wetting
of structural materials and in a loss of the insulating qualities of exterior walls. It also gives rise to such serious problems as chemical,
physical, or biological deterioration of the wall materials, and promotes corrosion of metal, spalling of brick, and rotting of timbers.
House wrap—an engineered construction fabric or membrane—can
be used on the outside of a wall, against some wall sheathings, to protect the sheathing from water and moisture. If properly installed, exterior house wrap placed over certain exterior sheathings can improve
comfort, energy efficiency, and will protect against moisture and water
damage.
Installed over wood or certain insulation sheathings, and under
siding or other exterior coverings, house wrap provides a protective
barrier which helps seal against leaks and drafts (air infiltration).
On the other hand, as some manufacturers of rigid sheathing panels point out, if their panels are properly installed, there should be no
265
266
HOW TO BUILD IT
air leaks through cracks or seams (or very minimal air leaks). If that’s
true, they say, then additional installation of house wrap over those
panels may actually create harmful conditions by trapping eventual
residues of wood starches from siding materials and from cleaning
detergents that may become trapped within the house wrap fabric
(thus plugging the fabric meshing so it can no longer breathe).
In many other situations, though, house wrap works hand-in-hand
with insulation. Using a clothing analogy, the home’s insulation traps
air in tiny pockets (like a thick cable-knit wool sweater does) to slow
the transfer of heat, while house wrap functions like a Goretex windbreaker does, when layered over the wool sweater. Where properly
used, house wrap should thus cover or seal:
■
Gaps between sheathing pieces or panels
■ Joints between the sole plate and sub floor along exterior walls
■ Gaps in drywall or plaster board and top and bottom wall plates
■ Where framing members meet in an outside intersection and
form a crack
■ Around window and door frames
■ Electrical and plumbing penetrations through top and bottom
wall plates.
An effective house wrap design resists tears in all directions, stands
up to windy conditions, with good tensile strength. Also, it should
only enable condensation to evaporate or drain away from the house
sheathing. Around windows and doors, house wrap can be used in the
sill rough openings before a window or door is installed. A straight
flash wrap is available for straight heads and jambs of windows and
doors to effectively seal gaps. House wrap tape is manufactured for
taping house wrap seams, tears, and openings such as holes and open
spaces around electrical boxes, venting ducts, and similar construction components and materials. Before deciding on a vapor/air infiltration system for your home, at least be aware of the various
strategies, and discuss them with your builder.
Make sure the particular house wrap or rigid panels are compatible
with the planned siding. For example, certain cedar and other wood
siding may need special add-ons to enable the siding to breathe from
both sides. Consider that many new products are in the process of
EXTERIOR WALL FINISHING
coming to market, so carefully research their pros and cons, then consider your house style and the weather conditions in your locale. It’s
far less expensive, and a much simpler process, to design the barrier
system for installation during construction—than to try to upgrade or
change systems at a later date.
Insulating batts in the exterior walls should have a vapor barrier
backing such as treated Kraft paper with the vapor barrier on or toward
the living-area side. If blown insulation or unfaced insulation is chosen, aluminum foil–backed drywall can be used, or friction fit or other
types of insulation can be applied after polyethylene sheet material is
stapled or nailed to the interior of the wall studs and ceiling joists. The
polyethylene film should not be less than 3 mils thick.
INSULATION
Underneath the sheathing and exterior wall covering, between the
studs, one of the following types of insulation will generally be used:
■ Batts or blankets—these are prepared thicknesses of expanded
glass fiber, mineral fiber, or organic fiber that are placed in the
walls between the studs. They should be faced (having a vapor
barrier on one side) in order to hold their form well.
■ Blown or poured—this is composed of loose expanded mineral
or organic fibers that are placed or blown into frame spaces.
They’re more useful for insulating existing buildings when it
would be impractical to completely remove the inner or outer
wall sheathings. On the down side, blown or poured insulation
may eventually settle and lose some of its insulating value.
If you choose to use vinyl or aluminum siding, remember that polystyrene and similar backer boards can be used behind the siding panels to provide extra insulation as well as added strength.
Or, this leads us to another recent product development that’s
become especially pertinent in this time of rising fuel costs, that of
exterior rigid foam insulation. Exterior rigid foam insulation is made
of extruded polystyrene or similar material that has an R-value of
about R-5 per inch of product thickness. It contains literally hundreds
of millions of densely packed air cells. Since air is one of nature’s most
effective insulators, the sheer volume of this compressed trapped air
267
268
HOW TO BUILD IT
gives this insulation exceptional thermal performance. It also prevents
air infiltration and resists moisture penetration.
In some cases, these panels can be installed over exterior sheathing
(as long as the total vapor/air-infiltration barrier system isn’t over engineered to prevent at least some healthy “breathing”). For example, a costeffective way to achieve a R-19 wall system is to install 1-inch extruded
polystyrene foam insulation to the exterior sheathing of a 2" by 4" wall
cavity filled with R-13 fiberglass insulation. Exterior sheathing, siding,
and interior drywall typically provide an R-value of R-1. A 2" by 6" wall
cavity filled with fiberglass insulation will give an even greater R-value.
The exterior layer of foam insulation will also help reduce road noise,
will help prevent air infiltration, and will increase comfort through less
radiant heat loss because the entire mass of the wall structure is covered.
Again, when dealing with barrier products, it’s important to have a
strategy that manufacturers and builders will somewhat agree upon, so
the combination of several different products will work in your favor—
and will not inadvertently cause moisture or air circulation/breathing
problems.
ENERGY-SAVING OUTDOOR PAINT
Many of these paints use microscopic insulating ceramic spheres in
their composition to help create a sturdy reflective, radiant barrier to
ward off the sun’s heat, especially in white and lighter shades of color.
They also protect against moisture, and provide an excellent choice
when sealing joints and narrow cracks and spaces around vents, trim,
and fastening devices.
Paints with insulating ceramics resist stains, corrosion, mold and
mildew, and can be scrubbed clean, help deaden sound, and are effective in hot and cold climates. They can be applied with brush or roller,
and are simple to use for touch-up tasks.
Table 11.1 lists insulation values of sidings.
INTAKE/EXHAUST HOODS
Request that the siding contractor provide waterproof maintenance-free hoods in colors that match your siding for dryer and other
intake/exhausts (Figs. 11.23 and 11.24).

MOUNTING PLATES
Color-matching mounting plates for mailboxes, hose reels, electrical outlets, coach lamps, and other lights and fixtures are usually
available in vinyl and plastic. While these may sound like “small”
details, they can all contribute to a handsome exterior—without
ungainly distractions caused by mismatching hardware (Fig. 11.25).

Many police, paramedic, or fire department personnel will tell you about the
amount of time lost nights trying to locate
a house for an emergency call when the
home’s address numbers are not readily

address number fixture.
They’re inexpensive to operate and
easy to read, day or night. They’re made
from maintenance-free vinyl or plastic
products that also come in colors to match the siding (Fig. 11.26).
AWNINGS
There’s something old-fashioned about a good set of fabric awnings.
Maybe it’s the additional level of privacy they provide when installed
over windows, doors, decks or patios. Or maybe it’s the additional
color they add, or their ability to be adjustable. They also protect—to a
certain extent—against rain, wind, and sunlight. In fact, canvas and
other fabric awnings block out or absorb up to 99 percent of the sun’s
harmful ultraviolet rays, and can reduce the amount of sunlight and

271
glare passing through windows by as much
as 94 percent. Awnings can thus reduce
heat gain through windows—up to 77 percent on eastern and western windows.
They’ll also protect indoor furnishings
such as carpeting, curtains, and furniture
from sunlight fading, while keeping the
inside environment cooler, with lower airconditioning costs. On the down side,
awnings eventually wear out. They’ll
need maintenance and eventual replacement as well as routinely being put up and
taken down, depending on seasonal
weather patterns; this could raise safety
issues, especially with second-story

awnings, awnings constructed of aluminum, plastic, or composite materials.
Especially where snow and ice are not issues, rigid awnings can
provide many of the advantages of their fabric cousins and can be left
in place year-round.
There are many types and styles of awnings. Consider these features if you decide to investigate their use on your home:
■ Do the units require minimal maintenance?
■ Are they self-storing?
■ Is the awning material resistant to
ultraviolet light, mildew, and water?
■ Is the awning operated with a man-
ual crank, or is motorized?
■ Is it an under-the-eave mount, or
flat-wall mounted?
■ Does
it have stainless steel or
other hardware that will not rust or
deteriorate?
F I G U R E 11 . 2 6

272
HOW TO BUILD IT
■ Are there oil-impregnated bearings, so there’s no need for lubri-
cation?
■ Do the units have strong, lightweight, rustproof frames with a
baked enamel finish?
VENTILATION GABLES
Ventilation gables can be critical to planning for sufficient air
movement into an attic or other “open” spaces beneath upper reaches
of the roof. Air movement will help remove dampness and hot air, thus
helping the insulation and lumber there. Some manufacturers offer copolymer construction gable vents with ultraviolet-stabilized colors
molded throughout, and fully screened for insect, bat, and bird protection. These units can be installed on all types of exteriors, including wood, vinyl, aluminum, stucco, hardboard, stone, and brick.
SIDING GENERAL CONSIDERATIONS
■ It’s a good idea to view the work of masons the builder is plan-
ning to use on your siding. Ask to see recent completed projects
whether they’re in brick, stone, or stucco.
■ Decide if you want a matching stoner brick mailbox or light
posts on either side of the driveway or walk before masonry siding is applied.
■ It should be stated in the contract that the builder should see
that only OSHA-compliant scaffolding is used for all elevated
work.
■ The exterior siding contractor should also quote on any wrought
iron railings needed.
■ The exterior siding contractor should figure in trim around the
doors, windows, and at the corners of the home. Flashing must
be installed at the head and sill of all door and window openings. Trim should be securely fastened and well caulked wherever needed. Request tinted caulk that matches the siding color.
■ House wrap fastened over plywood will help keep out wind and
water. Flashing at the base of the wrap will help carry off water
EXTERIOR WALL FINISHING
from the wall, and weep holes between bricks, stones, or in the
vinyl or aluminum siding will allow water to escape.
■ Wood siding should clear the ground surface for less chance of
wood-boring insect damage and decay from moisture.
■ The agreement should specify if any brick, stone, shingle, or
shake siding must be treated with water repellant after the siding has had sufficient time to “dry out.” For example, the contractor should not paint right after installation of wood, but
should wait until the wood has a chance to dry. If it shrinks after
being coated, that will leave unpainted strips of wood where the
pieces overlap.
■ No matter which siding you plan, ask the contractor to hand-
pick the best material for the front and back of the home, where
appearance is most important.
■ See that only exterior, nonrusting fasteners are used in all siding
applications.
■ Nails must be driven flush or countersunk.
■ All laps of siding must be parallel, and all joints should be stag-
gered between courses.
➤➤➤➤➤ POINTS TO PONDER
1. The exterior wall covering is the single most dominant feature
of a home’s outer appearance; its color and texture are the first
things noticed by anyone approaching the house.
2. Good design calls for simple lines, common sense in the selection of materials, harmonious textures and colors, plus good
proportions and scale.
3. A hash of contrasting materials, such as a bit of stone here,
some brick over there, with shingles and clapboards and stucco
all mixed together can lend an unattractive garish look to the
dwelling—even though individually those sidings are quite
attractive.
4. Brick and stone are more expensive than most other wall coverings, mainly due to installation costs. But they do make beautiful, unique exteriors, hold their looks indefinitely, need little

maintenance, and have reputations for durability and for helping home resale values.
Although cedar, redwood, cypress, and pressure-treated Southern yellow pine shingles and shakes are sometimes installed in
hot, dry climates without being coated with preservatives,
weathering everywhere is best controlled by applying recommended weatherproofing every few years per the manufacturer’s recommendation.
Only nonrusting fasteners should be used to attach exterior
wall siding, to prevent unsightly rust leaching and staining.
Stucco is a plaster-like material so popular with English Tudor
construction. It provides an excellent exterior finish, having a
long life span and needing very little maintenance. It’s really a
version of portland cement that’s troweled on like plaster to
either masonry or frame walls, with no seams or joints.
The vinyl, aluminum, and related siding industry is constantly
engineering improved materials. Do a thorough review of these
sidings before making a final decision. Consider the material’s
appearance, plus its ability to resist dents and scratches, to
hold its color and resist fading, and to provide insulation value.
Again, it costs about the same to install an inferior material, as
it does to put up quality siding.
After you decide on what kind or kinds of siding you want,
select only high-quality siding(s) and sealing caulks.
If your home is being constructed near others, consider how the
appearances of those neighboring dwellings may affect or limit
your own siding (and roof) selections. In other words, it’s prudent to consider the appearance of your home within its setting.

Stairs
W
ho can forget the dramatic confrontations in Gone with the Wind
between Rhett Butler and Scarlet O’Hara on a huge, spectacular
staircase?—the dominating structural feature of the deep-South estate
of Tara. And what about the shrieking panic of Martin Balsam in
Alfred Hitchcock’s Psycho, as he tumbles backwards away from the
murderer—down a stark wooden flight of stairs.
No doubt, staircases are custom-made for grand entrances and
exits. At the same time, stairways can be convenient and dangerous,
healthy and harmful, attractive and ugly, space-saving and spacestealing. They’re less expensive and much more practical than elevators or escalators, and they enable us to make better use of small
building sites by permitting several living levels to be positioned one
atop another. Staircases can be made of wood, metal, stone, concrete,
or any combination of construction materials having the strength to
do the job.
A stairwell is the term for a shaft or opening through one or more
floors of a house in which a staircase is constructed or placed. A completed stairway consists of the following (Figs. 12.1 and 12.2):
■ Stringers—diagonal or circular supports for the steps.
■ Treads—the horizontal upper surfaces of individual steps, the
part your foot steps on.

An open main stairway.
■ Risers—the vertical pieces between the treads. Some basement
stairways don’t have risers, but are wide open between the
wooden treads (Fig. 12.3).
■ Handrails.
■ Newel posts—the posts at the top or bottom of a flight of stairs
that support a handrail, or the central upright pillar around
which the steps of a winding staircase turn.
■ Balusters—any of the small posts that support the handrail of a
railing. In olden times, these were frequently elaborate woodwork. Latter-day balusters, railings, and posts are more likely to
be black wrought-iron or simple wooden handrails attached to
the sides of the stairwell walls.

GENERAL STANDARDS
1. Stairway angles. In staircase design and
construction you’ll find a rise and run
similar to that of a roof’s slope. The
angle of a stairway is determined by the
arrangement of the tread depths and
riser heights.
2. Stairway treads and risers. For safety’s
sake, all treads should be equal and all
risers should be equal in any one flight.
3. Stairway widths. Main stairways should
be at least 3 feet wide, clear of the
handrail(s) (Fig. 12.4). A basement stairway can be slightly narrower, with a
minimum clearance of 2 feet 10 inches.
F I G U R E 12 . 3

4. Stairway landings. The minimum
dimensions for a regular stairway landing is 3 feet square. For safety, landings
must be level and free from intermediate steps between a main up flight and a
main down flight.
5. Stairway framing support. This is the
required vertical structural framing
built to support all stairways from
underneath.

Stairway types.

HOW TO BUILD IT
STAIRWAY TYPES
There are four basic types of staircases
used in modern houses: straight stairways,
L-shaped stairways having a landing or
winders at the turn, U-shaped stairways
having a landing or winders at the turn,
and spiral staircases (Figs. 12.5 and 12.6).
Straight
Straight stairways are by far the stairways
used in most house construction today.
Advantages
1. They cost the least to build.
2. They’re the easiest to carry bulky items
and materials on.
Disadvantages
1. They’re dangerous. If someone happens
to trip at the top, a fall all the way to the
bottom could result. Small children
especially must be protected from them.
2. They’re tiring to climb because there’s
no space to stop and catch your breath.
F I G U R E 12 . 6
A spiral staircase.
3. They’re not very attractive.
L-shaped and U-shaped
Both of these stairway types were used frequently during past
decades when individual carpentry efforts were more predominant
than today’s prebuilt and space-saving methods.
Advantages
1. They have landings to rest on to catch your breath.
2. The landings provide good spaces to hang decorations or art.
3. They can be so attractive as to add character to a house.
STAIRS
Disadvantages
1. They’re more difficult to work into a house’s floor plan.
2. They’re more expensive to build.
3. They make it harder to carry large items such as bedroom furniture
up and down. This is especially true of narrow U-shaped stairways.
Spiral and Circular
Only people thoroughly familiar with spiral staircases should plan
them into their houses.
Advantages
1. They save space. Spiral stairways can be installed where you cannot possibly fit conventional stairs.
2. Because they’re rarely enclosed, they serve as attractive decorative
units that generally become focal points of the rooms they’re in.
3. They’re good for outdoor use to provide access to second-story balconies, decks, and regular rooms.
Disadvantages
1. The treads are not full depth at both sides. If you fall from the top
you can tumble a long way. Most people aren’t used to them. Spiral
stairways require a different gait to ascend than to descend; visitors
unaccustomed to them might find this a nuisance.
2. They’re almost impossible to use for moving large items such as
bedroom furniture between floors.
STAIRWAY STYLES
Regardless of their shape, stairways can be open on both sides,
open on one side, or closed in by walls on both sides. The most attractive seem to have one open-type support or stringer. That way at least
one wall provides a surface to hang artwork or plants, and the stairway
still looks and feels spacious—even if it isn’t.
As an added note, if you’re planning to use stairwell walls as a
gallery, arrange for blocking in between the studs while the wall is
281
282
HOW TO BUILD IT
being erected. Then heavy items can be fastened to the blocking if
need be, and not just into the weaker plaster or drywall.
WIDTHS AND HEADROOM
A staircase should be wide enough so two people can pass each
other on the steps and furniture can be transported up and down with
a minimum of trouble. Consider 36 inches as a minimum width to be
safe; 42 inches, if space permits, is ideal. Extra inches are especially
handy if a staircase is closed or makes a turn and involves winders as
in L-shaped and U-shaped types. If wider, they’re a lot easier to maneuver large pieces of furniture on.
The stairs should also be plenty deep for a good step. Twelve to 14
inches deep for individual treads is both the maximum and ideal
range. The headroom between any part of the tread on any individual
step and the nearest vertical obstruction should not be less than 7 feet,
preferably 7 feet, 6 inches (Fig. 12.7).
RAILINGS
F I G U R E 12 . 7
A stairway’s minimum headroom.
Stairway railings can be fun to think
about. Should you have a flashy brass rail?
Or maybe an intricately carved wooden
one? Then again, maybe it would be better
to put up a half wall and top it off with a
nice modern slab of sanded-smooth oak
with a great, round finial (ornamental post
top) at the bottom to keep youngsters from
using the rail as a slide. Above all, a railing
must be sturdy. Although local building
codes must be followed or exceeded, they
often define “sturdy” as being able to support a weight or push of 200 pounds at any
point of the rail.
Stairway railings can add a lot to the
safety and decor of your home, so keep the
following in mind:
STAIRS
283
■ Stairways should be equipped on each side with permanent and
substantial handrails 36 inches in height from the center of each
tread. Narrow stairs can get along with one rail, but wide stairways should have two.
■ The railings should be continuous from floor to floor, even
when there are landings.
■ All handrails should have rounded corners and a surface
smooth and free of splinters.
■ Since you’re going to need some kind of railing(s) anyway, you
might as well use railing that adds to the attractiveness of your
home.
FOLDING AND EXTENSION STAIRWAYS
Folding or extension stairways are widely used for necessary and
convenient access to attics, finished living quarters, or out-of-the-way
closet storage spaces (Fig. 12.8). Some models, especially the wider
ones, have handrails on both sides. These are preferable.
Many of the narrower models, with
only a single handrail, are best installed to
drop down along an adjacent wall, if possible. The use of these stairways also
saves the floor space of the room or area
below the device, which allows for freer
planning. Most folding or sliding extension stairways come completely assembled for installation in a prepared opening
and are attached to a ceiling door so you
just have to reach up and pull them down.
The two most popular types are rigid
extension units that slide up and down
parallel with their pull-down door, and
three-section units held together with
hinges. When not in use, the hinged secF I G U R E 12 . 8
tions fold up into a compact bundle that’s
stored on top of the closed door.
A pull-down extension staircase.
284
HOW TO BUILD IT
Although these setups provide somewhat less sturdy means of
access than access gained by permanently fixed stairs, the folding and
extension models are not used as frequently and are the better choice
for top-level spaces.
The folding units fit into homes with floor-to-ceiling heights of 7
feet 6 inches to 8 feet 9 inches. Rigid extension stairways are available
in many more sizes ranging from 7 feet 6 inches to over 16 feet.
All folding and extension staircases that fold or slide up into
unheated areas such as attics must not be overlooked when it comes to
insulation and air infiltration. The door of a pull-down stairway
should be hinged on one side of the frame and equipped with latches
so that when closed, the door can be snugly pulled against a rubber
seal to prevent drafts.
Insulation to match the other parts of the attic floor should then be
placed on top of the door and around the sides of the frame. Caulking
compound can be applied around the seam at the juncture of the door
frame and subfloor.
SAFET Y
POINTERS
BASEMENT STAIRS
Due to the “hard” nature of typical basement staircases, coupled with
the fact that they usually lead to a plain concrete floor, take extra
precautions to safeguard them from babies, toddlers, and other young
children. Consider the use of a closure on the basement door, one that
slowly shuts the door after someone goes through, similar to the setup
on a storm door. To remain effective, the unit should also have a cylinder
that can hold the door open if something needs to be transported up or
down the stairs. Another feature to arrange for is plush-type, padded
carpeting at the bottom of the basement stairs, securely fastened to the
floor or placed with nonslip backing, so that it won’t pose a tripping
hazard. If someone accidentally slips down the stairs, the plush padded
carpeting at the stairs’ bottom will help soften the impact.
STAIRS

Outdoor basement stairs.
EXTERIOR STAIRWELLS
Exterior stairwells that lead from basements and lower living levels
directly to the outdoors face special problems that are solved by construction specifications different from those used for inside stairways
(Fig. 12.9).
1. Exterior stairwell sidewalls are normally formed with poured concrete or concrete blocks.
2. The steps are practically always made of poured concrete.
3. The entrance doors, single or double, can be wood, but should
preferably be steel with a wood center or core. These composition
steel/wood doors hold up very well against moisture in all climates.
4. The bottom of an outside stairwell should be lower than the basement to prevent a direct flow of water into the house. A 6-inch sill
285
286
HOW TO BUILD IT
is standard, with a stairwell drain installed to convey excess water
into an appropriate drainage area.
➤➤➤➤➤ POINTS TO PONDER
1. Although stairway appearances are important, they’re not as
important as stairway safety. Safety considerations should
come first with stairways.
2. Main stairways should be at least 3 feet wide.
3. Stairs should be plenty deep for a good step. Twelve to 14
inches deep for individual treads is an ideal range.
4. The headroom between any part of the tread on any individual
step and the nearest vertical obstruction should be between 7
and 71⁄2 feet.
5. There should be at least one sturdy handrail on each stairway.
6. Stairways must be well lit, with lighting controls at the top and
bottom of each stairway.
7. Folding or sliding stairways, such as pull-down units to attics,
must be frequently inspected for loose fasteners caused by
opening and closing actions, vibrations, and even alternating
hot/cold temperature changes.
8. Consider putting up a barrier in the attic around a pull-down
stairway so that no one accidentally steps, kneels, or leans
against the folded stairway from above (which could cause the
stairway and the person to tumble to the lower floor).
9. Be aware that hardwood stairs can be beautiful, but they can
also be quite slippery, especially when wet or when people
walk on them in stocking feet.
10. If you’re planning to use stairway walls as a gallery, arrange for
blocking in between the studs while the wall is being erected.
Then heavy items can be fastened to the blocking if need be,
and not just into the weaker plaster or drywall.

Windows
I
magine a house without windows and you’re likely to conjure up
some prison-like dwelling or subterranean earthen home
constructed into the side of a hill. Windows, large and small, perform
many important functions in the typical home. First of all, they
provide natural lighting. Second, they admit fresh air for ventilation
and allow oxygen-depleted used air to be expelled. They also provide
access for passive solar-heating sunrays, and openings in the house’s
outer shell for air-conditioning units. From within the house, they
enable the occupants to attain a visual continuity with the outdoors
and provide exits to those same outdoors in case of emergencies.
GENERAL CONSIDERATIONS
When planning for and selecting windows for your house, keep the
following points in mind for each potential window candidate:
■ Insulating and anti-air infiltration properties.
■ Ease of operation.
■ Necessary maintenance.
■ Ease or difficulty to clean.
■ Its style and how it will fit in with your overall exterior scheme.
287

288
HOW TO BUILD IT
■ Price—a cheap window could cause a loss of any initial savings
through consequential increases in heating, cooling, and maintenance costs.
DRAWBACKS
Like any other feature in a house, windows can also have their
drawbacks:
1. Large expanses of glass increase heat loss during periods of cold
temperatures and become a source of unwanted, and at times
uncontrollable, solar heat gain during warmer months.
2. In the summer, windows not only let the hot sun in to make the
inside of a house uncomfortably warm, but they also permit sunlight to fade the color from carpeting, paneling, furniture upholstery, and practically anything else.
3. In addition to providing views that might not always be pretty,
windows can turn a house into a goldfish bowl by enabling outsiders and strangers to see into the interior living areas.
4. Windows require a fair amount of washing—a chore no one
enjoys. Every now and then a child’s softball smashes through
one, or a limb from a nearby tree gets blown too close, and they
must be replaced.
5. Windows are the first surfaces in a house to fog up when the interior humidity rises. They can stream with condensation, which
might ruin the finish on the sills.
6. Windows can admit annoying neighborhood noises.
7. When not secured properly, windows provide encouragement to
burglars and intruders.
8. Windows become ugly black mirrors from inside when you turn
on the lights at night.
9. Windows require expensive curtains, draperies, and blinds that
also need periodic cleaning.
10. If not carefully and tastefully selected and located, instead of improving the appearance of a house, they can actually detract from it.
WINDOWS
WINDOW TYPES
When selecting from the 11 basic window types used on today’s
modern houses, there’s no reason why you can’t employ two or three
types of them as long as they look nice together. At the same time,
there’s no reason why you can’t combine one type of movable window
with a fixed window, or even with another type of movable window in
the same opening. The tightest-sealing and most energy-efficient window types, including casement, hopper, tilt-turn, and awning use
long-lasting compression-type weather strip seals.
Casement Windows
A casement window is a miniature version of a hinged door, except
it’s opened and closed with a crank or lever mounted on the inside of
the window sill (Fig. 13.1). Thus, you don’t have to disturb a screen or
additional storm sashes, which might be mounted on the inside—
although add-on storm windows and screens can also be installed on
the outside of casement windows. A latch locks each sash tightly.
Advantages
1. Because of their method of operation, casement windows are ideal
for installations behind counters and hard-to-reach or difficult-to-

HOW TO BUILD IT
move furniture. Wherever you can’t stand right next to the window
for leverage, or can’t reach the entire window due to its high placement, you won’t be able to comfortably position a double-hung
window and should opt for the casement.
2. They offer excellent sealing against air infiltration when they latch
against compression weather stripping.
3. Depending on the particular design, interior and exterior surfaces
can be cleaned from inside the house.
4. Since the entire sash opens, a casement window admits 100 percent of an available breeze.
5. Casement windows can be outfitted with automatic openers.
Disadvantages
1. You have to carefully consider where you locate casement windows in
relation to outdoor activities. They shouldn’t open out onto terraces,
porches, decks, or sidewalks where people can bump into them.
2. Because the screens or storm windows are fastened to the inside,
they hinder fast exits through the window openings if needed during a fire or other emergency.
Double-Hung Windows
These are the most common windows found in construction today.
The double-hung window has two sashes or panes that slide up and
down in channels or tracks called stiles. As a rule, the sashes are the
same size; but in some cases, the bottom sash is taller than the top
sash. The two sections are held in place by either springs or friction. If
by friction, it’s a sign of a good, tight fit (Fig. 13.2). Look for models
with ventilation limit latches that enable the windows to vent in a
partly open position, for recessed tilt latches that allow easy window
cleaning access, and for a sloped sill for rainwater runoff.
Advantages
1. Because they’re held firmly in place, double-hung windows rarely
warp or sag.
2. Unless they’re painted shut, double-hung windows are simple to
open and close as long as you can stand directly adjacent to them
for good leverage.
WINDOWS
FIGURE 13.2
Double- and single-hung window operation.
3. Relatively little air leakage occurs around the edges.
4. They can be cleaned from the inside if the sash is removable. The
older models had pulleys and weights suspended within the walls
to help the windows open and close—they had to be cleaned from
the outside. Some modern double-hung window sashes can be
popped out of their stiles, to the inside, for convenient cleaning and
replacement.
Disadvantages
1. If you will have to reach over a counter or piece of furniture to open
and close them, double-hung windows will be difficult to operate
and shouldn’t be used.
2. These windows can never open to more than half of their total area.
3. Even when they’re open only an inch or two, double-hung windows are likely to admit hard-driven rain.
4. If the sashes aren’t removable, the only way to clean them is from the
outside—with a ladder when they’re located on second-story levels.
Single-Hung Windows
Not as popular as their double-hung cousins, the single-hung window looks exactly like the double-hung unit but differs in that the sin-
291
292
HOW TO BUILD IT
gle-hung window’s top sash is fixed. It can’t be moved. Only the bottom half of the window can be screened.
Advantages
1. Because half of this window is sealed shut, there’s somewhat less
maintenance and less chance of air leakage.
2. The cost of a single-hung window is less than that of a similar doublehung model.
Disadvantages
1. Ventilation is limited to the bottom part of the window opening.
2. Washing a single-hung window can be a problem unless the lower
sash is removable.
Awning Windows
Awning windows are hinged similarly to casement windows, but along
their top edge so they swing out and up when you turn a crank or lever or
simply give them a push (Fig. 13.3). Some units are made with special
hardware that provides pivot action—the top
of the sash moves down as you push the bottom outward. The screens and storm windows are installed from the inside.
Advantages
1. They can be opened wide enough so
you can get almost 100 percent of possible ventilation—even during a rainstorm—without letting in water.
2. They can be used as clerestory windows, placed high in walls to provide
natural light and ventilation while
assuring privacy and leaving a maximum amount of wall space for furniture
placement.
FIGURE 13.3

3. They offer an excellent seal against air
infiltration when they latch closed
against compression weather stripping.
WINDOWS
293
Disadvantages
1. Awning
windows
shouldn’t
be
installed overlooking porches, decks,
terraces, or sidewalks because someone
might run into their open projecting
sashes.
2. Because they slant, open sashes are so
exposed that they become dirty in short
order and require more frequent washing than any other type of window.
3. As with casement windows, having
storm windows and screens mounted
on the inside can hinder a quick escape.
Hopper Windows and Tilt-Turn
Windows
Hopper windows are the reverse models of awning windows. Hinged or pivoted
at their bottom, they open inward and
downward from their top so that the entering air flows upward (Fig.
13.4). Operated by a lock handle at the top of the sash, they’re most
commonly used in basements and clerestories. Screens and storm windows are installed on the outside.
A tilt-turn window is a variation of a hopper window in which, by
turning one handle on a tilt-turn window 90 degrees, the window
switches from a hopper design (tilts in at the top just a little) to a
swing-in casement window (Fig. 13.5). In the hopper position, the
window can be left open in a rainstorm without water leakage. In the
casement position, they are easy to clean from indoors. Tilt-turn windows are also very airtight and efficient because the weather stripping
seal gets compressed when the window is closed.
Advantages
1. Hopper windows provide almost 100 percent of possible ventilation.
2. Both their inner and outer surfaces can be easily washed from the
inside.
FIGURE 13.4

294

Tilt-turn window opening positions.
3. They offer an excellent seal against air infiltration when they latch
closed against compression weather stripping.
Disadvantages
1. Hopper windows interfere with draperies and curtains and are
impossible to darken with shades when opened.
2. Because they stick out inside a room or hallway they can cause traffic problems in living areas of a home.
3. Because of their unusual open position they can be difficult to exit
from in case of an emergency.
Horizontal Sliding Windows
In effect, a horizontal sliding window is a double-hung or singlehung window laid on its side (Fig. 13.6). With some units, both sashes
slide from side to side in a channel; in others, only one sash (usually
the right sash) slides. In still others made with three panels of glass,
the two outer sashes slide to the center over a fixed sash that is twice

the width of each sliding sash. Look for ventilation limit latches that
enable the windows to vent in a partly open position, for recessed tilt
latches that allow easy window cleaning access, and for a sloped sill
for rainwater runoff.
Advantages
1. As with double-hung windows, because they’re held firmly in
place they won’t warp or sag.
2. They’re easy to open and close as long as you’re standing next to
them.
3. Relatively little air leakage occurs around the edges.
4. Washing is usually easy because many sashes can be removed from
the inside of the house.
5. Horizontal sliding windows are a good choice in locations where
you want an operating sash with a large expanse of glass and a minimum number of framing members to obstruct the view. No other
operating unit fills this requirement as well.
295
296
HOW TO BUILD IT
Disadvantages
1. Horizontal sliding windows cannot be opened to access more than
50 percent of their possible ventilation space.
2. They will admit driving rain into the house.
3. If you must reach over a counter or piece of furniture to open and
close them, horizontal sliders are difficult to operate and should
not be used.
Fixed Windows
Fixed windows are panes of glass mounted in frames that are
installed directly into a wall (Fig. 13.7). They can’t be opened and
closed, and can be ordered in a variety of sizes, shapes, and glass
types.
Advantages
1. They’re the most weather-tight windows available.
2. Because they can’t be opened, they don’t require screens or hardware.
3. They’re less expensive than other windows.
FIGURE 13.7
Fixed windows.
WINDOWS
Disadvantages
1. They can provide no ventilation.
2. They’re impossible to exit from in case of an emergency.
3. They must be cleaned from the outside.
Glass Block Windows
Glass block windows are installed like concrete blocks, course by
course. Glass blocks allow light to enter a room and, at the same time,
provide privacy. Standard (plain) as well as fancy “designer” glass
blocks are available. These blocks are not solid glass. Instead, each unit
consists of two hollow 1⁄4- to 3⁄4-inch-thick glass half-blocks fused together
under high temperatures. As the air inside the fused block cools, an
insulating partial vacuum is formed within the block (Fig. 13.7).
Advantages
1. When set in mortar, glass blocks are airtight, reducing the likelihood of drafts, dirt, allergy-causing particles, noise, and even burglar entry. They’re efficient year-round and minimize interior glare
and the fading of carpet, furniture, and furnishings.
2. Some “designer” glass blocks have patterns etched in their glass
such as wavy finishes, raised diamonds, stippled textures, or fluted
surfaces. Any of those can add character to a room.
3. Glass blocks can be purchased with color tints to blend or contrast
with interior designs.
Disadvantages
1. They can’t be opened or seen through.
2. They can’t be escaped through.
Bay Windows
A bay window consists of three adjacent windows or sections of
windows in a series. Two side sections are angled back from each side
of a straight center window or section of windows (Fig. 13.8). An
entire bay window unit can be made from combinations of windows
such as casement or double-hung windows on the sides and a fixed
center section.
297
298
HOW TO BUILD IT
FIGURE 13.8
A bay window.
Bay windows are ideal when you want to increase both the real and
apparent size of a room. They’ll also add a graceful note to an otherwise rather severe facade.
Advantages
1. They open up a 180-degree view and add space to a room.
2. They not only increase ventilation but also enable you to scoop in
breezes traveling parallel to the house walls.
3. They form a delightful niche for sitting or dining near. They’re
often featured in designer rooms and houses and they provide considerably more light than conventional window arrangements do.
4. They provide an excellent place for growing houseplants.
5. Bay window roofs may be shingled to match the house roof, or they
can be roofed with copper for a distinctive, traditional look.
WINDOWS
Disadvantages
1. At least the center part of a bay window must be cleaned from the
outside.
2. Because this arrangement protrudes out from a wall, it’s not as
energy efficient as other window installations.
Bow Windows
The bow window is a close relative of the bay window, and they’re
often confused with each other (Fig. 13.9). The bow window is gently
curved rather than angled and is considered a more graceful feature
when used in a house’s living area. The bow window receives its name
from the arrangement of a series of windows that arc out from the
house’s exterior walls.
Because of their curved shape, bow windows are necessarily made
up of relatively narrow sashes or of many small fixed panes. When
FIGURE 13.9

299
300
HOW TO BUILD IT
sashes are used, they’re generally the casement and occasionally the
double-hung type. With casement windows, either all of the sashes
can open, or only the two end panels, or only the end panels and every
other intermediate panel. When double-hung windows make up a
bow, only the end panels open. Bow windows are also available in
models in which none of the sashes open, with fixed large- or smallpane styles.
Advantages
1. They open up a 180-degree view.
2. Not only do bow windows increase ventilation, they enable you to
scoop in breezes that run parallel to the house walls.
3. They form the same kind of delightful niche found with bay windows, for dining near, growing plants in, and sitting in.
Disadvantages
1. Because they protrude, they are not as energy efficient as windows
closer to the walls.
2. These windows are usually narrow or small, so there’s little opportunity to escape through them in case of an emergency.
3. Some of their sections are normally fixed, and cleaning will have to
be done from the outside.
Garden Windows
F I G U R E 1 3 .1 0
A garden window.
Garden windows, also referred to as
greenhouse windows, project from a
home’s exterior by about 12 inches and
have glass roofs as well as vertical glass
panes (Fig. 13.10). Inside glass shelves or
expanded metal shelving across a garden
window allows the placement of plants
and admits sunlights from top to bottom.
The insulated glass and tight seals minimize winter heat loss. Some models have
insulated curved center window sections
that eliminate the need for center frames.
WINDOWS
Others use side-opening casement windows that hinge on the side
near the house. Many come with double lock latches on each side for
security and an airtight seal when closed and latched.
Numerous units employ vinyl frames (some foam-filled for extra
insulation value) that come in white, tan, and brown. For severe cold
climate locations, certain models afford extra protection for the plants
during winter, with rigid foam insulation sandwiched between the
seat and sides.
Advantages
1. They offer practically the same excellent spaciousness and ventilating possibilities as those available with bay windows.
2. They are great for growing cooking herbs in or near the kitchen.
Disadvantages
1. They cannot be easily escaped through.
2. They may be difficult to clean.
Jalousie Windows
A jalousie window is made up of a
series of narrow horizontal panes or glass
slats that open outward with a crank. (Fig.
13.11)
Advantages
1. They can be opened far enough to gain
virtually 100 percent of available ventilation.
2. They can be opened during rainy
weather without admitting water into
the room.
3. The airflow from jalousie windows can
be adjusted in any amount or vertical
direction.
4. They’re easy to open over a counter or
furniture.

HOW TO BUILD IT
Disadvantages
1. They possess many small glass sections that need to be cleaned.
2. They’re difficult to wash from the inside.
3. They’re very poor for preventing air infiltration.
4. Jalousie windows are impossible to exit from in case of an emergency.
Skylight Windows
Skylight windows do two things better than other windows can:
they admit more natural light and distribute the light more evenly.
They also make rooms look larger and can help equalize the light in
a room that might have windows on only one side. Frequently, the skylight chosen is a fixed window unable to be opened. Fixed skylights
come in many shapes—dome, smooth, low-profile curb, pyramid, and
ridge (Fig. 13.12). The same windows also are available in models that
can be opened and closed.
Another kind of roof skylight window is a single sash that pivots at
the sides about a third of the way down from the top. When opened,
the bottom swings out and the top swings in. It can be held open at any
angle—even completely reversed for easy washing from the inside.
In a third type of roof window, the sash is hinged at the top and
raises like an awning window to give an unobstructed view while
keeping out rain. The outside of the more progressive models is
washed with a special tool provided by the manufacturer.
Skylights and roof windows should generally be installed on the
south side of homes located in cold-climate areas, or on the north side
of dwellings located in warm-climate places. In colder areas, consider
a clear skylight or roof window combined with an insulating shade or
storm window. In warmer areas, use frosted or tinted skylights that
open to vent excess heat and have shades for blocking out the sun
when needed. The tinted glass will help reduce illumination while
cutting down on glare and heat gain.
Sun-screening capabilities with skylight or roof windows include
Venetian blinds, pleated shades, and roller shades. Venetian blinds
come in thermal units operated manually or electrically. Pleated
shades offer lighting gradations from soft filtered light to darkness.
WINDOWS
303

Skylight windows.
Various colors and shades are available, with different insulation values. Roller shades are often a choice of homeowners looking to work
within a limited budget.
Roof windows can be installed in convenient-reach locations such
as attics and “extra” or “nook” rooms. Some of these windows open to
a full 45-degree angle to satisfy egress requirements for emergency
escape.
Ventilating skylights are available in low-e insulated glass, with
optional insect screens. Units positioned out of a person’s normal
reach can be operated with a number of control systems (with manual
or motorized control rods), including the following:
304
HOW TO BUILD IT
■ Electric programmable units with timers that can be set to open
or close the windows automatically at desired times
■ Electric control systems with switch keypads
■ Units with infrared remote controls similar to a hand-held tele-
vision remote control, for convenient operating of vent skylights
and sunscreening accessories
Advantages
1. Skylight windows permit installation of smaller and fewer windows and simplify interior decoration and furniture placement by
allowing more uninterrupted wall space in a room.
2. They can be used to illuminate rooms and areas that share no outside walls for regular windows, such as inside bathrooms and halls.
3. They supply privacy without sacrificing any natural lighting. Also,
some models open for fresh air.
4. Skylight windows can provide more flexibility in the planning of a
house because you needn’t have to include sidewall windows in
every room and because they can effectively add useful space (such
as in attics) to spaces otherwise dark and dreary.
5. During winter, the pros and cons of a high-quality skylight are
about a wash, as the skylight loses more heat than does an insulated
attic floor or ceiling, but does reduce the need for electric lighting
during the day and provides some passive solar heat gain during
sunny weather. However, during summer, a vent skylight is an
energy saver since the hottest indoor air rises to the ceiling where
the skylight vent exhausts it. This creates a natural air flow, drawing fresh cooler outside air indoors.
Disadvantages
1. Because heat rises, skylight windows tend to be less efficient than a
plain windowless roof or ceiling in cold weather, especially during
times when the sun is not shining. Because of this, consider only skylights that have a minimum of double-glazed glass (not all of them do).
2. They can be difficult to clean. The fixed types must be cleaned from
above. Leaves, dust, and even ice buildup during winter can pose
real problems.
WINDOWS
3. Provisions need to be made for draining off water—either condensated moisture or water that collects from rain and melting snow.
TYPES OF GLASS
There are three types of glass panels typically used to construct modern windows: plate glass, tempered glass, and insulating glass panes.
Plate Glass
This is the standard glass normally used in house windows. It can
be plain or tinted to reduce glare and can be doubled up to sandwich
in a thin airspace for insulating qualities. When struck or put under
stress, it shatters into pieces that are usually very sharp. It’s an excellent material for windows, though, because it can be manufactured
free of flaws and distortions.
Tempered Glass
Tempered glass panes are three to five times stronger than those
made of ordinary plate glass. Tempered glass should be used in doors
and in glass panels adjacent to doors and other areas where it is likely
that people, especially children, might run into or fall against them. In
fact, many building codes require the use of tempered glass in wall
areas that are within 4 feet of any door. When struck or put under
stress, tempered glass develops hairline cracks or breaks into many
small, rounded pieces instead of into the sharp, ragged pieces that
come from standard plate glass. Auto windshields are a common
example of tempered glass.
Insulating Glass
This glass exists in two forms. One is a special double or triple
sheet of glass (double or triple pane/double or triple glazed) separated
by an airspace(s) with the glass edges welded or formed together to
make airtight center spaces much like the liner for a thermos bottle.
The other consists of two or three sheets of glass held in the frame with
an insulating airspace in between. Double-pane insulating glass used
in most stock windows is made of two panes of sheet glass having a 3⁄8
to 1⁄2 inch of airspace between them. Triple-pane glass windows consist
of three panes of glass with approximately 3⁄8 inch of airspaces between
each pair of panes (Fig. 13.13).
305
306
HOW TO BUILD IT
In this day and age, it no longer makes
sense to install windows having only a
single thickness of glass. Instead, all exterior windows located in living areas or
heated areas of a house should be doubleor triple-paned. The additional expense is
well worth it; you should save enough in
fuel and energy costs to more than make
up for the initial investment within a few
years and have a more comfortable home
in the meantime.
More advantages to using double- or
triple-pane windows as opposed to a combination of single-pane sashes and storm
windows are that the multipanel windows
offer a better appearance; are easier to
clean; and provide increased soundproofing, a permanent installation, and even a
better overall price. In all multipane windows, specify that the thickness of the
sash is at least 13⁄8 inches.
Self-Cleaning Glass
F I G U R E 1 3 .1 3
Insulating glass double- and triple-pane windows.
Several manufacturers produce windows made of glass that’s designed to selfclean. Due to chemical compounds
embedded within the surface of the
molten glass during manufacturing, when
the window is exposed to sunlight a chemical reaction helps disintegrate many foreign materials that collect on the glass,
such as tree sap, pollen, or dead insects.
Also, water doesn’t bead up on self-cleaning glass; instead it spreads out in sheets
that wash away loose debris like a
squeegee.
While windows with self-cleaning
glass cost more, they enable more of the
WINDOWS
sun’s rays to enter through the cleaner glass—warming interior spaces
during winter and helping to reduce energy costs.
Additional Glass Options Include:
■ Low-e glazings are special coatings that reduce heat transfer
through windows. The coatings are thin, almost invisible metal
oxide or semiconductor films placed directly on one or more
surfaces of glass or on plastic films between two or more panes.
The coatings prevent heat loss during winter and slow heat from
entering the house in the summer.
■ Spectrally selective coatings are considered to be the next gen-
eration of low-e technologies. These coatings filter out from 40
to 70 percent of the heat normally transmitted through clear
glass, while allowing the full amount of light transmission.
■ Insulated glass contains at least double panes surrounding a
sealed air space, offering an insulated layer between you and
the elements, plus warm-edge spacers that minimize heat and
cold conductivity between outdoors and indoors. Filling the
gap between the panes with a low conductivity harmless inert
gas adds about another R-1 of insulation value to the window,
and also helps block out noise.
■ Heat-absorbing glazings are glass that has tinted coatings to absorb
some solar heat (but they can’t absorb it all). Some heat continues
to pass through the glass by conduction and re-radiation.
■ Warm-edge technology uses low-conductance spacers to reduce
heat transfer near the edges of insulated glazing. The edge spacers are what hold the panes of glass apart and provides an airtight seal in an insulated glass window. The better models carry
a long warranty against spacer and seal failure. New glazing
technologies with warm edges and insulated frames not only
reduce energy costs, but make homes more comfortable as well,
even helping to reduce incidents of frost and condensation.
■ Reflective coatings greatly reduce the transmission of daylight
through clear glass. Although they typically block more light
than heat, reflective coatings, when applied to tinted or clear
307
308
HOW TO BUILD IT
glass, also slow some heat transmission. These coatings are commonly applied in hot-climate locations, where protection from
the glaring sun is critical to comfort. Care must be taken, though,
since the reduced cooling energy that results may be somewhat
offset by a resulting need for additional artificial lighting.
■ Visual transmittance (VT) identifies the see-through quality of
the glass. Windows with high visible transmittance are easy to
see through and admit plenty of natural daylight. The VT in residential windows ranges from a shady 15 percent for some
tinted glass, up to 90 percent for clear glass (the higher the number, the clearer the glass). To most people, glass with VT values
of 60 percent or more looks clear. Any value below 50 percent
begins to appears dark and/or reflective. Besides giving you a
nice view, high-VT windows can save energy in certain conditions because you’ll need less artificial illumination. But can
you have your high-tech insulated glass and see through it too?
Not all of the time. Some tints and coatings that block heat also
reduce visual transmission, so make sure you actually see and
look through any special glass you may be considering, before
specifying it for your home.
CONTROLLING HEAT
Windows, for all their wonderful qualities, can also be considered
as thermal holes or passageways. An average home may lose up to 30
percent of its heat or air conditioning energy through low-quality windows. Energy-efficient windows save money every month. Their
higher initial cost can be offset in many ways. One way is that a
smaller, less expensive heating and cooling system would be acceptable. Energy efficient, durable windows will certainly cost less in the
long haul because of less energy used, lower maintenance costs, and
avoidance of replacement expenses that will otherwise inevitably
come into play if inferior windows are selected.
All of this, plus the occupants will be a lot more comfortable in a
dwelling that’s built with good windows—due to the ways the windows help control heat. In short, when sunlight strikes a window, visible light, ultraviolet rays, and heat are either reflected, absorbed, or
transmitted into the building.
WINDOWS
309
During winter, a window with a lower glass temperature feels
colder partly because more heat is radiated from a person’s body
toward the window, than from the window to the person. Cold glass
can also create uncomfortable drafts as air next to the window is
cooled and travels downward to the floor. This sets up an air movement pattern that feels drafty and promotes heat loss. High-performance windows installed with efficient weather stripping result in
higher interior temperatures in winter, and thus greater comfort. During summer, windows with low solar heat coefficients reduce the solar
radiation coming through the glass, with its overly warm discomfort.
Windows lose and gain heat by conduction, convection, radiation,
and air leakage (Fig. 13.14).
■
Conduction is the movement of
heat through a solid material. With
less conductive material, head flow
is impeded. To control conduction,
look for multiple-glazed windows
with an approved low-conductance,
inert approved harmless gas
trapped between panes of glass.
Thermally resistant edge spacers
and window frames will further
reduce conduction.
■ Convection is another way heat
moves through windows. In cold
weather, heated indoor air presses
against the interior surface of window glass. The air cools off,
becomes dense and sinks toward the
floor. As this cooled air drops, warm
air rushes in to take its place along
the surface of the glass. The cycle
then repeats itself over and over, or
at least until the glass becomes too
warm to continue to cool the indoor
air. What actually happens is the
occupants feel too cold for comfort
F I G U R E 1 3 .1 4
Windows lose and gain heat.
310
HOW TO BUILD IT
and turn up their thermostat control. Unfortunately, this is
where excessive energy costs come into play. Each 1 percent
increase in thermostat setting requires an increased home
energy usage of about 2 percent. This heat loss or transfer is
expressed with U-values, or U-factors. U-values are the mathematical inverse of the R-values commonly used to measure the
effectiveness of thermal insulation. That means the lower the Uvalue, the higher its insulating value. Your window U-value
should be below 0.35 to be efficient.
■ Radiation is a third way heat can enter or leave a dwelling. You
can help control this process to your advantage with low-e glass
coatings, transparent metal oxides that reflect up to 90 percent of
long-wave heat energy, while passing shorter waves of visible
light. The shorter wavelength visible light is absorbed by the
floors, walls and furniture. It re-radiates indoors from those surfaces, all while the long-wave heat energy is reflected back outdoors. In cold climates, the low-e glass reflects the internally
produced radiant heat waves back into the house, again while
admitting visible light. The shorter wavelength visible light is
absorbed by floors, walls and furniture, and re-radiates from
those surfaces at the same time the long-wave heat energy is
reflected back inside. For heating, low-e coatings thus work best
when applied to the internal or inter-pane surface of the interior
window pane. Conversely, for cooling, low-e coatings work best
applied to the inter-pane surface of the window’s exterior pane.
■ Air leakage is a fourth way that heat is lost (or gained) from a
home. In short, air leakage siphons a large percentage of an average home’s heating and cooling energy to the outdoors. Some of
this is unavoidable, of course. When someone enters or exits a
dwelling, there’s bound to be some exchange of indoor and outdoor air. It’s the avoidable air escape and exchange that windows (and doors) must address. To control air infiltration,
quality windows need durable weather stripping and secure
closing devices. Hinged windows such as casement and awning
types tend to clamp more tightly against weather stripping than
do double-hung windows. But the difference can be slight; wellmade double-hung windows are certainly acceptable.
WINDOWS
311
How well the individual components of the window are joined can
also affect air leakage. Glass-to-frame, frame-to-frame, and sash-to-frame
connections must be well-fit and tight. The technical measurement
specification for window air leakage is measured in cubic feet of air per
minute per square of window. Look for windows with certified air-leakage rates of 0.01 to 0.06 cfm/ft or less. Lowest values are best.
TYPES OF WINDOW FRAMES
There are three primary types of materials used in window frame
construction: wood, metal, and plastic.
Wood Frames
Wood frames are the most handsome window frames available and
are often preferred for this reason alone. They can be purchased with
their exterior and side surfaces (the parts that abut the tracks or stiles
and face the outdoors) covered with a layer of tough vinyl or a layer of
aluminum with a coat of factory-applied, baked-on paint. The only
part of such a window frame that retains its wood surface is the interior section—what you can see that faces the inside of a room. That
inside surface is the most important part of
a window frame from an appearance point
of view. It can be stained, varnished, or
painted to match or complement the rest
of a room’s decor. The choice of colors for
either the vinyl- or aluminum-clad surfaces are usually limited to white, brown,
or bronze.
Because no staining, varnishing, or
refinishing is ever required to the nonwood surfaces, maintenance there is
extremely infrequent. And the wood part

inside the room, will rarely need attention

HOW TO BUILD IT
Advantages
1. A primary advantage of wood-framed windows is their appearance.
They look less clinical than aluminum or steel sashes. As such,
wood is favored in many residential applications because of its
appearance and traditional place in house design.
2. Condensation is not much of a problem with wood frames as, it is
with steel and aluminum ones.
3. Wood frames can be successfully used with all architectural styles.
4. Wood frames are poor heat conductors, so they provide effective
insulating qualities.
5. Provided you select the wood frames having vinyl- or aluminumclad exteriors, the outer and inner track surfaces will be practically
maintenance-free.
6. The interior surfaces of wood sashes can be painted to match any
color scheme or can be stained and finished in natural tones to match
inside wood baseboard and other trim. Exterior surfaces of wood
sashes can also be painted to easily change color schemes if desired.
Disadvantages
1. If the exterior surfaces are not vinyl- or aluminum-clad, they’ll
need refinishing, especially if no awnings or substantial overhangs
are in place to shield the windows from rain, sun, and snow. If
uncovered wood frames are not treated to resist decay and moisture
absorption, they’ll rot in short order.
Metal Frames
Metal window frames are available in aluminum and steel models,
in natural finishes or various selections of anodized coloring. Aluminum windows became popular because people thought aluminum
models suffered from none of the problems associated with wood—
that they wouldn’t rot, swell, contract, warp, or need refinishing. This,
however, proved not altogether true. Near seacoasts and corrosive
industrial locales, aluminum frames can corrode so badly that they
need to be painted for protection. For these reasons, it’s advisable to
purchase aluminum or steel windows that are protected by factoryapplied finishes.
WINDOWS
A traditional heat conduction problem for aluminum frames can be
addressed during their manufacture by including a thermal break,
splitting the frame components into interior and exterior pieces by
using a less-conductive material to join them.
Advantages
1. They cost less than wood frames.
2. They lend themselves nicely to places that receive rugged use, such
as basement windows and garage windows.
3. They’re easy to operate.
4. They won’t warp.
5. Aluminum window frames are light, strong, and easily extruded
into the complex shapes required for window parts.
6. Aluminum frames are available in anodized and factory-baked
enamel finishes that are extremely durable and low-maintenance.
Disadvantages
1. Because aluminum and steel are excellent conductors, they permit
high heat loss from within a house through the window frames.
2. Also due to their conductivity, they cause excessive moisture condensation on the interior portion of the frames when significant
temperature differences exist between the inside and outside of the
windows. If you insist on aluminum- or steel-framed windows,
make sure you select a brand that has a thermal break—where an
insulating material separates the interior and exterior sections of
the frame. The most efficient and practical insulating materials
include plastic, urethane, epoxy, and vinyl.
3. Aluminum and steel frames often provide a looser fit than that of
wood frames, allowing for more air infiltration.
Vinyl Frames
Vinyl is an option for your consideration. Vinyl allows very little
heat and cold transference and is practically maintenance-free. Vinylclad wood makes for top-quality frames that combines wood’s extra
insulating properties with vinyl’s easy care. Most vinyl-framed win-
313
314
HOW TO BUILD IT
dows use multichambered hollow extruded frame and sash sections.
These chambers create multiple “dead” airspaces that provide insulation U-value and strength. Several manufacturers offer foam insulation inside the frame chambers. The major difference between
insulated vinyl and standard vinyl frames is improved thermal insulating capabilities.
Advantages
1. They are energy efficient and help reduce noise transmission.
2. They have good air and weather seals for reducing dust and pollens.
3. Vinyl comes in wood grain finishes, and one model actually has a
real wood composite on the side that faces the inside of the home.
4. Vinyl window frames do not require painting. Because the color
goes all the way through, there is no finish coat that can be damaged or will deteriorate; therefore the surface is maintenance free.
Plastic Frames
An available option on some window types is plastic frames. Plastic frames are lightweight and corrosion-free.
Advantages
1. Painting is never needed unless you decide to change their color.
2. They’re easy to operate.
3. They’re not as expensive as wood frames.
4. Plastic is not a good conductor; it doesn’t have the condensation or
heat transfer problems of aluminum or steel.
Disadvantages
1. The main drawback is their lack of strength. Wood, aluminum, and
steel frames are much stronger. Plastic frames are more likely to
break, especially during cold weather, when plastic turns brittle.
Fiberglass Frames
Fiberglass-framed windows can cost a bit more, but they may be
worth it to you. They seldom need to be caulked or painted and pos-
WINDOWS
sess high insulation values. Some fiberglass windows are available
with real wood interior sides. The strong fiberglass exterior sides provide the stability and can resist gale winds and driving rains while the
wood interior sides give the home a warm, comfortable look and feel.
Advantages
1. They remain airtight because fiberglass frame material expands
with temperature changes at almost the identical rate as window
glass, so the fit stays true during temperature swings.
2. The fiberglass exterior provides excellent strength and rigidity,
which makes these windows favorable choices in rough-weather
locations subject to gale-force winds and driving rain. Models are
available in many colors, and since fiberglass resists high temperatures, the paint can be baked on. These frames can also be hand
painted with good success, should you decide to change the décor
of a single room or of the entire house.
3. Many fiberglass-framed windows offer optional foam insulation
filling for additional energy efficiency.
4. Because fiberglass is stronger than most vinyl/plastic, it can have
smaller cross-sectional pieces and thus provide a proportionally
larger clear window area, allowing more free passive solar heating
during winter.
WINDOW SIZE AND ALIGNMENT
Make certain that the size of some windows, particularly in bedrooms, is large enough to escape from in case of a fire. As mentioned
previously, all sleeping areas should have at least one easy-to-open
window having an opening of not less than 7 square feet. Check local
building code requirements for window opening width and height, as
well as the sill height above the floor.
Also be aware that the size and placement of windows will limit
where you can comfortably arrange furniture. Major items such as
desks, sofas, bureaus, dressers, china cabinets, and buffets all normally require wall space. However, if window sills are high enough,
some furniture can be placed beneath them. Many pieces of furniture
are only 30 to 32 inches high.
315
316
HOW TO BUILD IT
Windows should be aligned in a pleasant manner, especially when
viewed from the outside. That typically means that windows across
each living level conform to one long horizontal line. Small windows
should line up with the top or bottom halves of large windows. Then
for maximum effect, have the tops of exterior doors line up with the
F I G U R E 1 3 .1 6
Comparison between poorly and correctly aligned windows.
WINDOWS
window tops on the first level (Fig. 13.16). When possible, arrange vertical window placements directly above one another.
WINDOW LOCATION
No matter where you locate your windows, all exposures will be
able to provide a sufficient amount of natural light (Fig. 13.17). Southern exposures, with their high sun angle, offer the most light and the
best opportunity to control and use sunshine to good advantage. East
and west exposures are the most difficult to control, having lowangled rays, with the west being particularly troublesome. Northern
exposures, lacking direct sunlight, are the easiest of the four to control.
For the typical home, windows on the north side of the house are discouraged. However, when windows are required due to an unavoidable or advantageous orientation or positioning of the dwelling—such
as a master bedroom overlooking a scenic view—a northern exposure
can be well suited to the dwelling.
Other points to remember:
■ Horizontal window openings are especially useful for control-
ling light from southern exposures.
F I G U R E 1 3 .17

317
318
HOW TO BUILD IT
■ Vertical window openings are most useful for controlling light
from eastern and western exposures.
■ Windows located high in a room offer the most illumination and
the deepest penetration by natural light.
■ Clerestories and skylights offer good possibilities for lighting
interior spaces in a home.
■ Windows can be located to illuminate parts of a house or room
where specific tasks will be undertaken. Of course, artificial
lighting should also be arranged for times of insufficient daylight or during evenings.
WINDOW VENTILATION
In addition to providing natural light, the second major function of
windows is to provide ventilation to get rid of stale air in the home
(Fig. 13.18).
Large openings allow for the best natural ventilation when
arranged to encourage a crosscurrent of air. Openings should be oriented to pick up prevailing summer breezes.
Good airflow occurs when the inlets and outlets are approximately
the same size. Better airflow can be attained by having a larger ratio of
outlet-to-inlet area. A combination of openings can direct airflow as
desired; openings placed lower in the wall surfaces result in better
cooling than those placed higher in a room.
Exterior features such as overhangs, porches, fences, garages,
shrubs, and trees can be used to block or encourage airflow.
If you plan to install central air-conditioning in the house, you
won’t need side windows for cross ventilation. By not putting them in,
you’ll save their installation costs, plus money on energy costs.
STORM WINDOWS
Storm windows cut down on conductive heat losses and gains,
depending on the season, by impeding air infiltration and by providing an airspace between inner and outer panes of glass (Fig. 13.19).
On most types of windows (double-hung, single-hung, awning,
sliding, and jalousie) conventional storm windows are put up in the
WINDOWS

HOW TO BUILD IT
fall and taken down in the spring. But they
can also be used to keep cool, conditioned
air in a home during summers in warm-climate locations. On casement windows,
storm windows are frequently fastened to
the outside of the sash.
Combination aluminum-framed storm
windows and screens are used on doublehung, single-hung, and sliding windows.
In cold-climate areas, they have generally
replaced conventional storm windows
because combination storm window/
screens can be left in place year-round. In
winter, they keep out the cold, and during
summer, the insects.
Two kinds of combination storm windows are available: double-track and
F I G U R E 1 3 .1 9
triple-track. Both include an upper panel
A triple-track storm window arrangement. of glass, a lower panel of glass, and a single
panel of screen. In the double-track
arrangement, both glass panels are fitted into separate channels or
tracks so they can move up and down independently of one another. In
summer, when ventilation is required, the lower panel of glass slides to
the top of its track and the screen panel is inserted into the lower half
of the track. During winter the screen is removed entirely and stored.
The triple-track storm window arrangement eliminates the necessity for putting in and taking out the screen because each of its two
glass panels and the screen all fit into their own tracks. You can convert from a storm window to a screen by simply sliding the lower glass
panel up and pushing its replacement screen down. In winter, the
screen can conveniently be stored in the top part of the frame, within
its own track. Although definitely more expensive, this setup is highly
desirable if it fits into your budget. You gain the flexibility to have
screens at a moment’s notice, or storm windows, and it sure beats having to lug and store screens someplace where they could get damaged
during the off-season.
When planning for storm windows, consider that caulking is
needed around permanently installed units, at the outer edges of their
WINDOWS
321
frames. Two weep holes must be kept open at the bottom edges of
each storm window to provide drainage and some ventilation, or
wooden sills might rot. To prevent corrosion and maintain a good
appearance, select only storm windows that have frames finished in
baked enamel or that are coated with a layer of maintenance-free
vinyl or similar material.
Key points to look for in a storm window are:
■ Installation with quality stainless
steel screws.
■ Low air infiltration rating.
■ No-gap
weather stripping. The
entire perimeter of the closed sash
should be sealed.
■ Baked enamel finish on the frames.
■ Tie-bar horizontal stiffeners result
in a more rigid assembly.
■ Double-strength glass.
■ Thick-gauge aluminum.
■ Low-e coating
■ Adjustable sill extender permits a
tight fit, even to uneven sills.
■ Energy Star labels present.
SCREENS
Most screens installed in today’s homes
are made of aluminum mesh (Figs. 13.20
and 13.21). Screens are wonderful conveniences. They let air in (or out) and keep
out insects and vermin. One recent innovation is a window with built-in screens
that pull down and roll up out of sight
within the window frame.

HOW TO BUILD IT
Aluminum Screening
Aluminum screening is rustproof and
resilient. It comes in bright or natural (silvery) finish, charcoal, and black. Charcoal
and black tend to be the most popular
because they provide excellent outward
visibility. Black aluminum is a top-of-theline screening product. It actually seems to
disappear into the background while you
look through it to the outdoors.
Fiberglass Screening
Fiberglass screening is typically vinylcoated for strength and durability. It’s
especially well suited for coastal areas. It
will not corrode, rust, or dent and is very
easy to handle.
Solar Screening
FIGURE 13.21
Screens.
Solar screening products are made of
vinyl-coated fiberglass, heavy-duty vinylcoated polyester, and louvered aluminum.
They provide protection against insects while blocking out two-thirds
of the sun’s heat and glare—and still allow good outward visibility.
Less heat and less glare means less summer energy consumption.
Pet Screening
Pet screens are heavy-duty, pet-resistant screens made from strong
materials such as vinyl-coated polyester. This screening fabric resists
tears, punctures, and other damages caused by pets, toddlers, or heavy
wear in high-traffic areas. They’re available in black and gray and are
ideal for windows, doors, and porches likely to take abuse.
SHUTTERS
The main purpose of outside shutters is to beautify the exterior of a
house, to harmoniously balance out the appearance of the windows.
Maybe years ago they would prevent an Indian’s arrow or a marauder’s
WINDOWS
bullet or grizzly bear’s paw from entering a
window, but they don’t anymore. In fact,
most of them no longer even close.
You can save money by using ornamental shutters made of vinyl, plastic, or aluminum. Vinyl and plastic shutters are
typically available in maintenance-free
colors and shades that will match or contrast with whatever siding you choose.
Their rigid one-piece construction comes
with the color molded throughout, and no
paint to chip or flake like the finishes of
traditional painted shutters can. Deep
wood grain textured models are also on
the market, in both open louvered or
raised panel designs. They’re less expensive than wood and don’t require costly
operating hardware. Vinyl, plastic, and
aluminum shutters are made in louvered
and raised-panel designs—usually in
black, brown, green, or white (Fig. 13.22).
Aluminum units are the stronger of the
three, but because the finish is only baked
on, and they’re exposed to the rain, sun, and snow throughout the
year, they’ll eventually need repainting. Vinyl-covered shutters, on the
other hand, are integrally colored so they don’t have to be touched up
even if damaged.
Shutters are typically installed by fastening them to window casings or adjacent wall surfaces with screws. But that also means there’s
no easy way to clean out wasps’ nests, bats, or debris that can accumulate behind the shutters.
Wood shutters present an additional problem: if they’re not adequately treated with wood preservative, they’ll rot. They require frequent stripping, sanding, and painting or staining, which can be quite a
time-consuming process, especially if the shutters are louvered. Like the
other site-painted items, painted wood shutters won’t clean as easily as
those having factory finishes. On the positive side, wood shutters can be
custom-finished and refinished to match any decorating scheme.

HOW TO BUILD IT
DIAMOND AND RECTANGULAR PANES
If you’d like to have windows with
either small diamond—or rectangularshaped panes, you could invest a small
fortune into obtaining them. Alternatively,
you could buy single-pane windows and
turn them into multipane ones with
devices called snap-in muntins. The
muntins are made of plastic or wood,
painted or coated to match the window
frames. They snap onto the back of the
window, on the inside, depending on the
style of window. You can remove them
quickly when you wash the windows,
then snap them back into the sash when
the glass is clean (Fig. 13.23).
Seen from the inside of a house, muntin
inserts are difficult to distinguish from
permanent muntins. From the outside,
FIGURE 13.23
although you might be able to tell that they
Snap-in muntins. don’t project through the glass, the insets
impart an appearance and effect of the real
thing at a much lower cost.
EXTERIOR CONTROL OF SUNLIGHT
Regular double- or triple-pane windows, even though they’re great
for controlling the loss or gain of heat through conductivity, cannot
prevent sunrays from entering and heating a room. This is good in
winter and bad during summer. There are tinted window coatings that
act like tinted glass when applied (as in a car windshield) or, to a certain extent, like sunglasses.
Wide roof overhangs, like wide-brimmed hats, will effectively
shade windows facing south. The same overhangs will also admit winter sun that strikes at a much lower angle. Overhangs, though, are not
very effective at shielding east and west windows, because the morning and afternoon sun rises and sets at low angles all year round.
WINDOWS
Canvas, plastic, or aluminum awnings
can successfully provide the overhang
needed to shade most windows during
warm weather (Fig. 12.24).
Also consider motorized awnings,
which can enhance the appearance and
comfort of an existing porch, deck, or patio
while stopping direct sunlight from hitting
windows and raising the house temperature. In addition, they protect carpeting
and furniture from sunlight fading and
stop the associated degrading effects that
gradually weaken the fibers of indoor furnishings. Beyond installing canvas, plastic, or aluminum awnings, deciduous trees An aluminum awning.
can be the answer (Fig. 13.24). Deciduous
shade trees planted on the south, west, and east sides of a home will
provide much appreciated shade during summer, and because they
lose their leaves toward the end of each autumn, sunshine will be let
through when you need it the most—during winter.
Sun Control Window Film
Window film is a relatively inexpensive feature to consider from
day one with your windows. It should be installed and approved by
the window manufacturer to protect the window warranty. It’s a clear
high-tech protective layer that’s applied over window glass to increase
the window’s visual clarity, shatter resistance, and ultraviolet (UV)
and other light-blocking ability. The film is treated with a variety of
thin metal coatings which result in a wide range of colors or shades,
appearances, and performance. Quality sun-control window film has
the following features:
■
Can block up to 99 percent of the sun’s harmful ultraviolet rays.
Ultraviolet light causes most of the deterioration and discoloration in furnishings.
■ The film also helps block out intense visible light that con-
tributes to fading of more sensitive colors and materials such as
natural dyes and fibers or works of art on paper.
325
FIGURE 13.24
326
HOW TO BUILD IT
■ Window film can reduce the amount of solar heat that passes into
the home. Solar heat levels build up on and damage furniture and
fabrics, which get almost hot to the touch. It causes temperature
changes that lead to dryness, warping, and general deterioration—particularly with wood, paper, and natural fabrics.
■ Can provide a clear, practically colorless appearance that’s crit-
ical for a good view—while reducing glare and eye discomfort
(similar to what a good pair of sunglasses does for the eyes).
■ Is wipable and scratch-resistant.
■ Helps holds the glass together if struck, for additional security
against violent weather, intruders, and accidental breakage and
personal injury.
■ Saves energy by reducing cooling needs during summer, and by
reflecting heat back inside the home during winter. It effectively
increases the insulation value of windows.
INTERNAL CONTROL OF SUNLIGHT
Be aware that curtains and drapes can be purchased with linings that
provide considerable insulating values. Look at the options before making a choice. In addition to conventional curtains and draperies, you can
also help control energy loss with roll-up shades, honeycomb shades,
cellular shades, Venetian blinds, and vertical blinds. Roll-up shades
come in many colors, patterns, and textures. The least-expensive ones
are made of a thin layer of vinyl. Vinyl-coated cotton shades are better.
Fiberglass laminated to vinyl results in the most durable and nicestlooking shades available. While most of these materials are translucent
or semitranslucent, some are designed to give complete darkness. Also
on the market are shades that are coated on the back to prevent and
reflect the incoming sunrays. The alternatives to fabric shades are those
constructed of slender strips of wood, metal, or semirigid vinyl.
When choosing blinds, honeycomb shades made of spun polyester
are extremely flexible, making them good choices to fit windows with
unusual shapes. The combs give this product a distinct look. They do
a fine job trapping air for good sound and thermal insulating qualities.
Some manufacturers claim R-values as high as 4.8. Cellular shades are
also good sound and thermal insulating, while the use of Venetian
WINDOWS
blinds is another common way of regulating available sunlight (Fig. 13.25). Venetian blinds of horizontal wood, metal, or
plastic strips or louvers are made in two
basic styles. The standard blind features 2inch-wide slats held in place by wide
cloth tapes. The miniblind has 1-inchwide slats held by slender cords. Simply
because it’s made of heavier material, the
standard blind is more rugged, flaps less in
a breeze, and can be used to darken rooms
more effectively. But the miniblind is more
attractive in every way, and when it’s
opened wide, the slats are almost invisible. These and other size units come in a
great range of colors and dimensions up to
a maximum of about 100 square feet.
Vertical blinds are, in effect, venetian
blinds turned on their side (Fig. 13.26).
They take the place of draperies and conventional blinds or shades on windows of
above-average size and are particularly
suited to unusually tall or wide windows.
They’re ideal for glass sliding doors
because they can be set to shut out glare without barring the view, and
won’t catch in the doors like draperies will.
When choosing blinds, consider the single-cord control, which
eliminates the looped cord design. Better yet, some advanced models
operate on a remote control system. No cords, no wiring, just batteries.
A few even feature a memory stop system to adjust the shades in the
same desired position each time.
HEAT LOSS THROUGH WINDOWS
The loss of heat through window openings can be reduced by the
following:
■
Adding additional layers of glass (storm sashes or panels).
327
FIGURE 13.25

328
HOW TO BUILD IT
FIGURE 13.26
Vertical blinds.
■ Sealing cracks around glass, sashes, and window frames to pre-
vent air infiltration.
■ Making sure that weather stripping and thresholds seal the door
edges tightly.
■ Installing heavy drapes on the inside to trap an additional layer
of air next to the glass.
■ Providing shelters for window openings in the form of over-
hangs, baffles, recesses, or plantings.
WINDOW INSTALLATION
■ Proper installation will protect the indoors from wind and
moisture, and will help lengthen a window’s useful lifespan.
WINDOWS
■ The rough opening for the window should be wrapped with
house wrap or prepared using an equally efficient insulation
material.
■ As the frame is set into the opening, it should be adjusted to be
perfectly square, plumb, and level. The distance between the
frame sides should be measured precisely to make sure there is
no bowing that would result in overly tight or loose sashes.
■ After the frame is fastened in place, the top must be flashed with
a copper or aluminum cap. To be effective, the cap must extend
up under the siding.
■ The gap between the window frame and wall frame should be
filled with a nonexpanding approved insulation.
WINDOW ENERGY-SAVING CONSIDERATIONS
■ Grilles mounted between double-glaze windows eliminate the
task of removing and replacing standard grilles whenever the
windows need cleaning. With the use of interior grilles, all you
do is wipe the glass clean.
■ The same goes for blinds that are enclosed between glass lay-
ers—their individual slats won’t need meticulous cleaning over
the years, and they’re protected from being accidentally caught
and damaged by children, cats, or clumsy bystanders. Cordless
models are available in which a sliding handle can raise, lower,
and tilt the slats. Some are adjustable by remote control.
■ Keeping the glass clean will help take advantage of solar heat in
the cold months and will admit higher illumination levels all
year around, reducing the need for indoor artificial lighting.
■ Double weather-stripped window sashes and compression seals
all the way around save energy.
■ In warm climates, look for windows with double glazing and
spectrally selective coatings that reduce heat gain.
■ In climates with both heating and cooling seasons, select
windows with both low U-values and low solar heat gain coefficiencies.
329
330
HOW TO BUILD IT
■ Another quality to look for in windows is an air-leakage rating
of 0.01 to 0.06 cubic feet of air per minute, or less.
■ Quality-built windows help your house stay cleaner due to less
air infiltration. Humidity is easier to control, and less electricity
will be used running vacuums for cleaning.
■ Awning windows can stay open through more types of weather
without needing to close.
■ Windows should be located for cross-ventilation to help reduce
cooling system use. Also, try to locate them away from highnoise areas so you will be able to leave them open more often,
for longer durations. In general, try to avoid placing windows
on the west side in hot-climate locations, and on the north side
in cold-climate locales.
■ General window features to look for include tilt-in sashes for
easy cleaning, removable screens, double- or single-hung or
sliding windows with interlocks at the panel’s meeting rails to
seal out air and water, tempered or “safety” glass for shatter
resistance, and fusion-welded frames for superior strength and
weather resistance.
■ Energy Star labels on the windows mean energy savings at
home.
■ Multi-pane windows having 3⁄8- to 1⁄2-inch spaces between panes
that are filled with low-conductivity inert gas.
■ Windows have traditionally been a weak link in a home’s exte-
rior when it comes to insulation capabilities. Insist on windows
with high R-values (or low U-values). That means storm window arrangements and at least double-pane (and sometimes
triplepane) windows made of glazed low-e glass. The e stands
for emissivity, a measure of the ability of glass to reflect or block
out long-wave radiant energy or heat and ultraviolet rays. The
lower the emissivity, the better the insulating qualities of the
glass. Low-e glazing and coatings reduce the fading of furniture,
curtains, carpeting, artwork and paints.
■ What’s next? Researchers have discovered that thin transparent
films made from metallic compounds such as nickel hydroxide
WINDOWS
and titanium dioxide, when sandwiched around window glass,
can yield effects similar to those available from “reactive” sunglasses that automatically darken as light levels increase. Simply,
these “smart” windows can remain transparent or clear when the
sun is low in the sky (or not out at all) and will slowly darken as
the sun rises and shines more forcefully later in the day. By blocking out midday heat from the sun, these photochromatic windows will reduce the amount of energy needed to run
air-conditioning and cooling units. As the sun sets and outdoor
light levels decrease, these windows gradually turn clear again.
➤➤➤➤➤ POINTS TO PONDER
1. Windows provide natural lighting, ventilation, passive solar
heat, openings for air-conditioning units and fans, visual contact with the outside, and exits during emergencies.
2. Consider the following characteristics when selecting windows: insulating properties, ease of operation, necessary maintenance, simplicity or difficulty to clean, and how the style fits
in with the overall exterior schme, and price.
3. Avoid making decisions on window selections mainly on
price. Inexpensive windows could really cost literally thousands of dollars worth of unnecessary heat loss over the years.
4. When choosing windows, ask yourself where and how the windows will be used, then match your needs with the most logical window types that will satisfy them.
5. When comparing windows, carefully review their insulating
values.
6. All sleeping areas should have at least one easy-to-open window having an opening of not less than 6 to 7 square feet.
Check local building codes for the opening height, width, and
sill height from the floor.
7. Be aware that the size and placement of windows will limit
where you can comfortably arrange furniture.
8. Horizontal window openings are great for controlling light
from southern exposures; vertical window openings work well
with light from eastern and western exposures.

Doors
T
here’s absolutely no doubt about it. You can’t have a house without
doors. Even primitive people had them—hides draped from poles
or vines. The Egyptians used woven reed mats that rolled up and
down, and early Britons employed huge stones that pivoted in a
circular fashion. Doors as we know them came into vogue during the
Middle Ages—sturdy wooden models held together by strips of
wrought iron or tightly fitted dowels.
A door provides a lot more than a simple entrance or exitway in a
house. A door is a moving part. It lets in air and seals out weather, dirt,
and noise. It takes up space, gets in the way, batters walls and furniture, and gets battered in turn.
Doors protect our privacy and belongings. They keep out the heat
and cold and allow ventilation of a closed-in space, even when shut.
They provide an access for natural light and bring the outdoors inside.
They’ll hold warmth-giving heat indoors during winter and cool air in
the summer. They’ll even pull teeth in a pinch.
When considering the entrances/exits that your house will have,
here are some questions to ask yourself about each door:
■ Will it operate easily and reliably?
■ Will it close securely?

There are five main types of doors that a house can contain: exterior, interior, storm, patio/garden, and basement.
Exterior Doors
In addition to providing privacy and security, exterior doors can
serve as effective weather barriers and sound reducers (Fig. 14.1).
They’re about 13⁄4 inch thick, 3 feet or more wide, and at least 6
feet 8 inches high. There should always be a secure layer of weather
stripping around an exterior door’s edges to ensure a tight weather
seal.
A house’s front door deserves extra attention because it’s the part of
a home visitors see first. The main entrance can make an impression
that adds considerably to a dwelling’s appearance, and even to the
home’s value and saleability. Because of the special importance of
front doors, they’re constructed differently in some respects from just
“plain” exterior doors. Details such as door caps, exterior moldings
and panels, windows or lights in or to the side of the door, and reeded
or fluted pilaster trim at the jambs all help make the front door something to be approached by its own sidewalk, lit up from the outside at
night, flanked by landscaped shrubbery beds, and protected by a roof
overhang.
Home security should not be forgotten in connection with any exterior doors. Security means a combination of the proper door locks and

hardware plus the ability to see who is calling before the door is
opened. One way that front entrance visibility can be accomplished is
by the installation of sidelights. Sidelights are narrow glass panes or
panels that run the height of an entrance door, placed either at one or
both sides of the door for added beauty and natural light. Two drawbacks are their relatively poor insulation value and their susceptibility
to intruders who, if the sidelights are not positioned correctly in relation to the door’s locks, can break the glass then reach inside to unlock
the door. Sidelights vary in size, but are normally less than 1 foot wide.
They’re available in many finishes and textures, some with low-e insulated glass for increased energy efficiency.
If there are no see-through sidelights, opt for a peephole to see
who’s outside before opening the door. Electronic touch pad and
remote-type entrance locks are available that eliminate fumbling for
keys at night.
336
HOW TO BUILD IT
For a side door or rear door having large
clear energy-efficient glass panes, consider
a unit with built-in blinds. Because the
blinds are sealed between tempered safety
glass, there’s no dusting or cleaning of the
individual slats; they should operate for
years with practically no maintenance
involved. Such inside-the-door or -window blinds will tilt a full 180 degrees,
which allows you to control sunlight levels and privacy with fingertip adjustment.
Some units even come with an option that
enables raising or lowering the slats just
like that of a traditional blind.
Interior Doors
FIGURE 14.2
A louvered door.
Interior doors exist mainly for privacy
and noise reduction. To be effective for
each, they must be well fitted. However, if
the house heating system depends on a free flow of air from room to
room, interior doors should be undercut at least 1⁄2 inch above the finished floors to permit air passage. Although this doesn’t apply to areas
having their own air supply and return outlets, remember that door fit
is still important. You don’t want doors to work too tightly, especially
over carpeting, because large amounts of friction will be created when
the doors are opened and closed.
Interior doors are available, in addition to flush and paneled models,
in full louvered, top and bottom louvered, or partially louvered with
either a top or bottom of paneling (Fig. 14.2). Louvered doors, while
more expensive than flush or paneled doors, are particularly useful in
locations requiring a free flow of air—namely closets or rooms containing mechanical equipment that must “breathe” to operate safely and
efficiently, such as water heaters and certain heating units and furnaces.
Storm Doors
If you elect to include an enclosed patio that leads to your back or
side door, it will provide an efficient air lock when you enter the house
from there during cold weather. Otherwise, storm doors provide protection from harsh weather and direct sunlight for your primary doors.
DOORS
They supply additional security, offer natural ventilation in the summer, and help
control heat loss and drafts during winter
and cool air loss during summer (Fig.
14.3), when, in both seasons, the storm
door creates an insulating dead air space
around the main door it protects. Most
storm doors are designed for easy
changeovers from screens in summer, with
fiberglass or other screening that will not
rust or corrode, to energy-efficient glass
inserts during winter. A storm door is
nothing to skimp on: good styling on the
front entrance storm door can add a lot to
the appearance of a house, and can also
cover up a nondescript front door.
When selecting your storm doors look
for the following:
■

glass and screen inserts should be
strong. If you can easily bend or flex the frames, they’re too
weak to make an adequate door.
■ A wrought-iron door with deadbolts and heavy hinges makes a
secure and decorative storm door. But well-constructed storm
doors are available in many materials as well, including wood,
aluminum, steel, and fiberglass.
■ Doors having a foam insulation core between their outer panels
or skins are very efficient. This sandwich-style construction
forms a rigid door with airtight seals, some with refrigeratortype magnetic closure strips.
■ A functional design will typically enable you to remove the
glass and screen inserts from the inside of the house, in a simple
manner. Separate screen doors with particleboard or wood cores
beneath their outer skins are rigid and durable.
■ A front storm door with a lot of screen/glass having attractive
bevels, or stained glass provides efficient ventilation and an
attractive entrance.
337
338
HOW TO BUILD IT
Home’s Appearance
The most decorative glass panes are beveled, etched, frosted, colored,
or accented with brass and other accompaniments. Smaller windows,
such as ornate ovals, are energy efficient. Low-emissivity glass with insulating inert argon gas in the gap is one of the most energy-efficient panes
available.
■
For the front storm door, select glass that helps enhance the
apearance. In some models, the decorative glass panes are further sandwiched between two outer panes, creating additional
insulating air gaps.
■ For a functional rear screen door, consider a unit having less
glass and an extra-strong frame. In hot climates, tinted glass
panes will help your air conditioner.
■ Look for weather tightness to prevent the entrance of water, cold
air, dust, and insects. A triple-track system is one of the best
designs, especially for the back storm door. If you lower the top
glass and raise the bottom glass panels a little, it creates a natural air current ventilation path. With such a system, you never
need to remove the screen or glass panels.
■ For ease of maintenance, a storm door with a self-storing glass
or screen has less glass area, so that the glass or screen panel can
be slipped down and hidden inside the door.
■ Make sure storm doors have easy-to-work locking mechanisms.
Some of the most secure units feature decorative wrought-iron
or aluminum channels, reinforced latches, anti-theft stops,
deadbolt pins resembling the pins from bank vaults, and nonremovable pin hinges. In addition, there is an increasing
demand for storm doors having keyed deadbolts that you can
lock from the outside for additional security.
Screening
RETRACTABLE SCREEN SYSTEMS
In our ever-present quest to save energy whenever possible, consider that improving natural ventilation instead of using air conditioning can help lower utility bills and improve indoor air quality. Enter
retractable screen systems.
DOORS
Retractable screen systems feature a narrow tubular housing
mounted vertically on a door frame (Figure 14.4). One small aluminum track is attached to the floor, and another to the top of the door
opening. A magnetic latch is fixed on the other side of the door opening, as seen in the illustration. When you open the door to go in or out,
or just for ventilation, you pull the handle on the screen that’s coiled
up within the cassette housing. The screen unrolls from the cassette
housing and adheres to the magnetic latch; there is a slight spring tension on the screening to keep it taut and
attractive. Premium screening kits use ball
bearings in the cassette for smoother operation. Nylon or other reinforcement strips
along the upper and lower edges of the
screen increase the unit’s durability.
SUN AND PET CONTROL SCREENING
This screen material can be used to block
intense summer sunlight when a window is
open and also when the same window is
closed, since the screening is located on the
outside of the window. A durable woven
vinyl-coated fiberglass product, its ribbed
weave is designed to block up to 70 percent
of the sunlight’s heat and glare. In addition
to reducing the amount of solar heat gain
(and keeping insects out) during summer, it
can also reduce heat loss during winter.
Another handy option for pet lovers is special dog- and cat-resistant screening made of
special vinyl coated polyester. It’s about
seven times more tear-resistant than ordinary screening.
Awnings
An alternative to a storm door is a
retractable awning, installed above its
companion exterior door. Many retractable
awning models open or close in just a few
FIGURE 14.4

339
340
HOW TO BUILD IT
seconds. An awning can protect the door from rain and sun. It can
keep the outer surface of the exterior door from not getting wet—
which also prevents water from dripping off the door onto the interior
floor each time the door is opened when wet. An awning will give you
the chance to open an umbrella as you first go outdoors, and an opportunity to be out of the rain as you unlock the door to go inside.
Patio/Garden Doors
Sliding glass doors and French doors will bring the outdoors inside
and will provide convenient access to a patio, deck, or garden. They’ll
make whatever room they’re part of appear larger than it really is, and
they’ll supply a flood of natural air and light when their screens are in
play. Practically any house built today will use one of these doors
somewhere within its walls (Fig. 14.5).
FIGURE 14.5
A glass sliding patio door.
DOORS
Factors to consider when selecting patio/garden doors are thermal
insulation quality, weather tightness, a secure locking system, and a
nice appearance.
Sliding glass doors are generally the bypass type. All units
include at least one fixed and one sliding panel. Some three-panel
models are available having a center panel that slides open in one
direction. For larger wall spans, four-panel models can be installed
having two center panels opening in opposite directions to make a
convenient access to large decks or patios. Sliding glass doors cover
a large span, so the strength of the frame is critical. Typical frame
material options include fiberglass, vinyl, wood, vinyl- or aluminum-clad wood or aluminum. Wood frames allow for a great range
of styles and contours; they should come treated with a water-repellant coating.
Fiberglass frames are very energy efficient, easy to maintain,
durable, and can be easily painted. Fiberglass expands and contracts
with temperature changes at a similar rate as the glass panes. This
reduces stress within the door and results in a long-term airtight seal
that helps prevent fogging. Fiberglass or vinyl frames should contain
foam or similar insulation inside the cavities for improved comfort
and lower utility bills. For a wood door appearance, select a model
having real oak or other veneer fastened to the fiberglass. A patio door
has a large amount of glass area compared to the frame area, so the type
of glass you select has a greater impact on energy efficiency than does
the frame material. For hot climate locations, consider doors with
tinted glass. For cold climate locations, opt for triple pane systems
with low-e glass.
French doors generally have a single panel that swings while the
other panel remains stationary (Fig. 14.6). Their wide frames are
attractive, strong, and can be energy efficient because there is less
glass area to lose or gain heat through. Grids inside the panels have
thick rails, stiles and transoms, with stained, beveled or etched
thermal glass. For exterior wood French doors, look for units that
have a waterproof material inserted in the bottom of each door stile
to prevent moisture damage. The block is covered by veneer so you
can’t see it, and the bottom rail and stile secured with glue and
dowel pins. The bottom rail needs to be sealed with waterproof
material.

Basement Doors
Outside basement doors allow you to transport such items as
screens, storm windows, and garden tools inside and out without
lugging them through the living areas. As mentioned earlier, basement doors are ideal for lower-level laundry rooms and will provide children with a means of getting to the back and side yards
without having to pass through the rest of the house. A basement
door should be at least 36 inches wide to accommodate large appliances.
Although basement doors should be able to effectively withstand
the weather and provide security against theft by themselves, attrac-
DOORS
tive basement stairwell covers can be purchased in ready-to-install
packages for use in all types of houses. They’re typically steel double
door covers that enclose and protect the outer stairwells leading to
basement doors.
DOOR STYLES
There are six basic styles of doors used throughout today’s modern
house: hinged, bifold, sliding, pocket, folding, and cafe.
Hinged Doors
A hinged door is essentially a simple rigid panel that swings open
and closed on hinges. It’s the most common type of door. Hinged doors
come in several architectural styles: flush, contemporary, Colonial
(six-panel), and glass (Fig. 14.7).
FIGURE 14.7
Hinged doors.
343
344
HOW TO BUILD IT
Advantages
1. When closed, hinged doors seal very well, curbing energy loss and
limiting the amount of sound transmission.
2. They’re initially one of the least costly type of doors to purchase
and hang.
3. They require a minimum amount of maintenance and cleaning.
4. They’re great for providing (on their back sides) space for doorhung shoe racks, necktie racks, belt racks, and for fastening all-purpose hooks to.
Disadvantages
1. They take up precious room to swing in. Consequently, they can’t
be used where there’s an obstacle in the way of their swing.
Bifold Doors
Folding doors.
Bifold doors are similar to those used in telephone booths, except
house bifolds open outward (Fig. 14.8). They’re used indoors only,
because there is no way to seal the cracks around their edges. The most
common bifold door consists of two fairly
narrow vertical panels that are hinged
together. One panel pivots next to the door
jamb; the other glides in an overhead
track. To open a bifold door, you either
shove the track-mounted panel toward the
opposite door jamb or pull the knobs fastened to the panels near the hinged edges.
Both methods of opening force the panels
to fold together back-to-back at right
angles to the doorway opening.
For small openings, a single bifold door
with two narrow panels is adequate. For
larger openings, the door is made with
wider panels or a double bifold door is
employed having four panels hinged
FIGURE 14.8
together. These doors are designed to be
operated from one side only and are best
DOORS
suited for closets. They’re useful in providing wide door opening coverage to shallow closets, making the most of the available square footage.
Advantages
1. When both sections of a bifold door are completely opened, you
have an almost clear view through the doorway. Or, you can have
access to one-half of the same closet without disturbing the door
covering the other half.
2. Bifold doors are ideal in cases where there is little room to swing a
regular door outward.
3. They allow the maximum opening to a closet with the minimum
extension into the room. Extending the height of the doors a full 8
feet to the ceiling eliminates headers and permits full-width shelves
and access to the upper area which would otherwise be lost.
4. In walk-in closets, space used for the “walking in” cannot be used
for storage. In shallow closets with bifold doors, however, the users
do not enter the closets—so almost all of the space within is available for storage.
5. Bifold doors come in styles that include solid or louvered panels.
The louvered doors have a beautiful appearance that alone makes
them popular with many homeowners.
Disdvantages
1. Bifold doors can come untracked or malfunction easier than simple
hinged-hung doors can. They won’t take the abuse that other types
of doors can take.
2. Bifold doors are somewhat more expensive than their counterparts.
3. Bifold doors cannot be used where a tight weather seal is required,
nor where the door must be operated from two sides.
4. Bifold louvered doors are time-consuming to clean and difficult to
repaint or resurface because of the many individual slats.
Sliding Doors
Sliding doors consist of usually two and sometimes three door panels that slide by each other (Fig. 14.9). These units hang from and
345
346
HOW TO BUILD IT
move along double or triple tracks
installed against the underside of conventional head jambs. To prevent operating
problems, sliding doors made of glass
should be of top-quality construction with
sturdy tracks, double or insulated shatterproof glass, and mohair or other stripping
laid along the door’s tubing edges for maximum insulation.
Advantages
1. Sliding doors can be used wherever
doors are needed, but door swing space
or projections are not permitted.
FIGURE 14.9
Sliding doors.
2. Sliding doors are easily maintained and cleaned.
3. Glass sliding doors are wonderful for expanding a view and for
making rooms seem a lot larger than they really are.
Disdvantages
1. Sliding doors give access to only half (or when three doors are
involved, to one-third) of an opening at once.
2. These doors are sensitive to any settling that might occur in a
house. The sliding doors can stick against the bottom floor guide,
which causes the doors to ride up and either jump or damage the
hanging tracks and trolleys.
3. Sometimes the screen inserts to glass sliding doors can be a nuisance if they’re not fitted exactly because they tend to pop out of
their tracks.
4. A cheaply made closet sliding door, when handled gently, will do
the job, but a cheaply made glass slider that isn’t weather tight and
fitted correctly will let in a lot of cold or hot air and can be difficult
to operate.
Pocket Doors
A pocket door slides in and out of a pocket built into the wall framing of partition walls. Their use with load-bearing walls is usually
DOORS

impractical. One excellent use is with a small bathroom or mudroom,
to prevent the room’s occupant from having to squeeze around the
door. (Fig. 14.10).
These space-savers can have silent-action rollers and rubber stopping bumpers inside the pockets so the doors will work without clatter. A pocket door recedes or slides in and out of a pocket built into the
wall framing, instead of swinging out in an arc like a hinged door does.
Standard hinged doors waste a lot of space; they take away from possible furniture placements, picture hanging, shelving installations,
and the like.
347
348
HOW TO BUILD IT
A well-placed pocket door will save roughly 8 to 10 square feet of
floor space. Also, while pocket doors themselves may not directly
lower your utility costs, they will allow you to build a smaller square
footage house that provides the same usable amount of floor space. A
smaller house has less wall and roof footage, thus less area to heat and
cool.
Another energy benefit of pocket doors is that they allow heating
and cooling systems to operate more efficiently because when you
open a pocket door there is no restriction to air movement, allowing
better circulation. Standard hinged doors can hinder air movement
and cause (however slightly) heating and cooling systems to work
harder. Manufacturers offer beautiful wood pocket doors made from
oak, cherry, walnut, and others, supported by sturdy steel-reinforced
split studs.
Advantages
1. Pocket doors are useful in locations where there is little room to
swing a standard hinged door out of the way due to interference
with traffic or the operation of other doors.
2. When open, pocket doors are completely out of the way (disappeared into a wall). They take up no floor or wall space and they
don’t obstruct the door opening even a fraction of an inch.
Disdvantages
1. Pocket doors should be installed only in partition walls, not walls
that are load bearing.
2. A wall that has a door pocket built into it should not contain electric wiring in that section of wall. You’ll have to place electrical
outlets and the light switch on the other side of the doorway.
3. Avoid locating a pocket door in a wall that will be tiled. Vibrations
from frequent opening and closing of the door could eventually
crack the grout and loosen the tiles.
Folding Doors
Folding doors are made of many thin, narrow vertical strips or
creases that fold back-to-back into a compact bundle when the doors
DOORS
349
are pushed open (Fig. 14.11). The simplest folding models have very
small strips that are tied together with cords. Most, however, have
wooden or metal slats about 4 inches wide that are hinged together
with vinyl fabric. In all cases, these doors hang from and run in a track.
They open and close between the door opening’s side jambs.
The main applications for folding doors
are in closets, laundry niches, and some
storage pantry-like areas in the garage,
basement, or hallways. They can also be
used to divide large open spaces into two
smaller rooms.
Advantages
1. They don’t swing out or protrude from
doorway openings. Their accordion
sections fold up into a small bundle
when opened.
Disdvantages
1. Folding doors give scant protection
against fire and noise.
2. They don’t operate very smoothly.
They’re not made as sturdily as other
doors and cannot stand heavy use well.
3. A main objection of homeowners is that
folding doors don’t look like doors.
Rather, they resemble stiff draperies.
Folding doors are generally neither
strong nor secure and they have a tendency to wave in a strong draft.
Cafe Doors
These are the doors you’ve probably
seen a thousand gunslingers walk through,
into television and theater saloons.
They’re the double swinging doors on the

short side—about 30 to 60 inches long—
installed on opposite sides of an opening
roughly midway between the top and bottom of a passageway (Fig. 14.12). They’re
attached to the opening’s walls or jambs
with gravity pivot hinges that enable the
doors to be pushed open in either direction, only to be closed automatically once
a person passes through them. Cafe doors
are available in both louvered and paneled
designs.
Because you can push your way
through them without using your hands,
these doors come in handy in places
where you’re likely to have your hands
full, such as between a kitchen and dining
room, where the cook is likely to shoulder
his or her way from the kitchen carrying a holiday turkey. Cafe doors
don’t provide much privacy from noise or odors (then again, who
wants to hide the delicious smells that waft from a kitchen stove?), but
they will block the sight of stacks of dirty dishes in the kitchen sink
from guests in the dining room.
Advantages
1. They’re inexpensive and easy to install.
2. They’re simple to use.
3. They add a unique and attractive character to the interior of a
home.
Disdvantages
1. They provide little protection from fire and noise.
2. Because people are constantly pushing against them, they’re difficult to keep clean. If louvered, they’re time-consuming to wash or
resurface.
3. Children can be injured running in and out of them.
DOORS
DOOR OPENINGS
Door openings are permanent features of a house that should be
well thought out in advance. Here are some pointers to consider:
1. Door opening heights should be a minimum of 6 feet 8 inches or 7
feet. For greater flexibility, though, consider a front door opening
that’s 8 feet tall and 42 inches wide, for moving large pieces of furniture through. An alternative is to select a door having a decorative side light panel that opens. The extra 14 inches or so will
greatly save time that would otherwise be spent by movers who
must carefully lift and manipulate large furniture pieces sideways,
backwards, or upside down.
2. A front door should be a minimum of 36 inches wide—which is
still a tight fit for numerous oversize pieces of furniture available on
the market today. If the front door width is any less, then the house
should have another outside door at least 36 inches wide so you’ll
have the ability to move large items in and out. The recommended
thickness of a 36-inch+ exterior door is at least 1 ⁄ inches.
3
4
3. Secondary outside door openings to a basement, kitchen, laundry,
or garage can be 32 inches wide, with thicknesses of 1 ⁄ inches.
3
8
4. If you happen to position a bedroom door at a right angle to the end
of a hallway, make sure the hallway is extra wide, and the door
opening is 36 inches, or you’ll never be able to maneuver large
pieces of furniture such as dressers and headboards into the room.
5. Consider each individual passageway if you want interior doors to
open inward or outward, as safety and convenience dictate. Basement stairway doors should always open away from the stairs.
6. When planning patio/garden openings, figure that they consist of
sliding and stationary glass panels with widths of at least 36 inches
per panel.
HINGED DOORS
Because hinged doors are used in every house in some fashion,
exterior or interior, they deserve additional comment:
351
352
HOW TO BUILD IT
1. They are easier to open and close than all other doors except
swinging cafe doors.
2. They permit you to use their backsides for storage space, a major
advantage in closets.
3. Their operation is noiseless except when slammed.
4. When properly hung, exterior models close tightly and stop drafts,
dirt, and insects from penetrating around the edges.
5. Exterior and interior doors should be hung with three hinges.
Ball-bearing hinges typically provide the smoothest operation.
The middle hinge helps support the door while maintaining correct alignment. At the same time, on hollow doors there is typically a horizontal reinforcement board placed through the door
center to provide a sturdy base or support for the doorknob hardware. If you plan to install a doorstop with a hollow door, position the stop where that center reinforcement board runs. If the
doorstop is placed elsewhere, it may punch a hole in the unsupported facing.
6. Interior doors should swing into the rooms they close off from
hallways. Otherwise they interfere with hallway traffic.
7. Doors on hall closets must obviously swing into the hall, however,
and it’s often advisable to swing a kitchen door into a hall so it
doesn’t create traffic problems within the kitchen work areas.
8. Whenever possible, bathroom doors should swing in; but if the
bathroom is too cramped, the door can be hung to swing outward.
9. Doors between adjoining rooms other than bathrooms can be
swung whichever way will cause the least inconvenience.
10. Doors at the head of stairways must swing away from the stairs.
11. Whether a door should be hinged on the right or left depends on
which position will interfere less with furniture placements and
passage through the doorway.
12. Ideally, storm doors should be placed so that they can swing back
into a corner out of the way.
13. Every exterior hinged door (and other types for that matter)—
front, back, or side—should have a step down to the outside, a sill
DOORS
353
forming the bottom part of the frame and entrance. This 8-inch
step down is to prevent water from entering the house during
heavy rains or snows.
PET DOORS
In warm-climate regions if you own a dog or cat, you might consider installing a pet door next to one of your side or rear entrances
(Fig. 14.13). Several companies manufacture ready-to-install units that
are two-way, self-closing, silent, chewproof, energy efficient (fitted
with a weather seal), and lockable.
The main reason that pet doors are energy efficient is because a pet
exiting and entering through a small pet door prevents the full-size
exterior door from opening for those same tasks. A full-size exterior
door opening allows a substantial amount of heated or cooled air to
escape outdoors. Then whatever conditioned air is lost must be
replaced, thus increasing energy usage and cost. Units are also available with foam insulation inside the metal rise and the height adjustment components for further energy savings and noise reduction.
Consider that pet doors are available for
practically any situation, even panels constructed to fit in a glass or screen door
track, as are units available having 1⁄2-inch
dual pane insulated glass with foam
weather stripping on both edges. Some
models have a locking steel close-off cover
that keeps animals in or out. A pin lock is
available for security.
Advantages
1. You needn’t be present to let your pet in
and out during the day or night.
2. You needn’t worry about heating or
cooling the great outdoors by leaving a
front or rear door propped open while
you peer into the darkness and whistle
for your pet to come home.

HOW TO BUILD IT
Disadvantage
1. What might happen if your neighbors install the same types of door
for their pets?
PET DOOR CONSIDERATIONS
■ Units can be purchased that mount between 2 by 4 or 2 by 6
framing studs. Other designs include units that are complete
panels which mount in a sliding glass patio door track with a
pet door built in at the bottom. Units are also on the market to
custom-frame in an irregularly sized door.
■ The pet door or panel should have a fully weather stripped, soft,
two-way flexible flap, with magnetic closures to keep the flap
secure, or an electromagnetic release equipped with two collar
keys that have a beeper to indicate when a unit’s battery is running low. A collar key is a tiny device that attaches to the pet’s
collar—typically operates on two AA batteries. Without a signal
from the key, the pet door will not open. This system effectively
keeps out neighbor’s pets, plus squirrels, rodents, and other
wild animals.
■ Some models have settings such as “In Only,” “Out Only,”
“Locked,” or “Full Open,” in case special circumstances arise,
such as your cousin visiting with his or her pet that also needs
to go in and out throughout the day.
■ Several units come with an “in/out” indicator that lets you
know which way the pet went last: in or out.
■ A “break-in” alarm is available on some models, which goes off
or “chirps” if the pet door is forced open or smashed in.
■ Some manufacturers claim their doors will help wipe off mos-
quitoes and other bugs as the pets come and go.
DOOR CONSTRUCTION
The construction of interior and exterior doors is substantially different from one another (Fig. 14.14).
DOORS
Interior Doors
Interior doors can be built out of wood,
plastic, metal, or any combination thereof.
A solid wood door is the best and most
expensive interior door available. Solid
wood doors do a good job controlling
sound between rooms. They are made by
sandwiching a wooden core between two
sheets of high-quality hardwood veneer
such as birch, oak, mahogany, or pine.
Lighter-duty hollow-core doors can have
the same expensive veneer faces, but
sheets of sturdy wood-grain plastic also
make a practical, easy-to-clean surface.
The lowest-priced hollow-core models are
frequently covered with less durable wood
composition board.
When selecting door veneers, keep in
mind that birch and oak doors hold up better than mahogany or pine. Oak and birch
are harder woods that can resist greater
impacts.

Door construction.
Exterior Doors
Exterior doors can be categorized as wood, steel, and composition
patio doors.
THRESHOLDS AND SILLS
No matter what kind of door it is, a sturdy threshold is needed.
Door models having an adjustable threshold are excellent choices. An
adjustable threshold can be easily adjusted up or down with a screw
driver—which can help make and keep the door airtight, quiet and
energy efficient while sealing out dust, dirt, moisture, and drafts (Fig.
14.15). At the same time, located on the bottom of exterior doors, a
multi-fin threshold seal provides further defense against air penetration (Fig. 14.16). For ultimate protection in high exposure severe
weather areas, look for a composite substrate bumper swing-out sill.

The accompanying seal increases with pressure against the door to
keep out air and water. When an exterior door is installed, it’s critical
that a generous amount of caulk be applied beneath the door’s threshold, with a few beads run on top of the sill plate, and that insulation
is carefully placed around the rest of the door frame to keep out
drafts.
EXTERIOR WOOD DOORS
There are two basic styles of exterior wood doors: flush and paneled. Flush doors are simple flat-surfaced doors that can be constructed with particleboard cores between two outer surfaces of a
durable wood such as a high-grade fir, or a solid lumber core between
the two outer faces. The latter are much stronger—a better choice, and
the most expensive. Paneled doors have decorative designs cut into
them. Both flush and paneled models can be made with various
amounts and shapes of glass inserts. If you desire the highest insulating efficiency along with the beauty of real wood, several manufacturers produce real wood exterior doors having insulated cores, and, for a
DOORS
weather-tight fit, triple weather strip seals. There are even models featuring engineered wood for additional strength.
Advantages
1. They’re beautiful, particularly when stained to show off their grain.
2. They lend themselves to an infinite variety of designs and can even
be customized by a manufacturer to your specifications.
3. They can be sawed and planed to fit existing door openings or new
openings that are not carefully made, or openings that later warp
because of settling.
4. Solid-core and insulation-core wooden doors have good insulating
qualities and are relatively soundproof.
Disdvantages
1. If not taken care of, they may expand, warp, crack, shrink, and
cause sealing problems.
2. They must be periodically refinished.
3. Wood doors are combustible.
EXTERIOR STEEL DOORS
Most steel doors are really part steel and part wood: steel sheets
fabricated around a wooden frame in which urethane foam or another
insulation material is sandwiched to provide outstanding protection
against cold and heat.
Steel doors are more practical than doors made of wood. They’re
designed to prevent the principal cause of wood door failures—
warpage that results in improper closure and air infiltration. They also
resist cracking, splitting, splintering, shrinking, and bowing. Newer
door frames provide a thermal break between interior parts and exterior surfaces, eliminating winter condensation inside.
Other features that apply to many steel door models are adjustable
thermal-break thresholds, magnetic weather stripping for uniform
sealing, and fire-resistant qualities that result in excellent safety ratings. The steel-skin design makes these doors efficient and maintenance free, with the thickness of the steel skin and door width being
357
358
HOW TO BUILD IT
fairly good indicators of overall door quality. Thicker steel provides
better stability and dent resistance and offers considerable protection
against intruders.
Remember, when comparing steel doors, a lower gauge number
represents a thicker steel skin. Partly for security and partly to maintain a tight fit, units are available with a multipoint deadbolt lock—the
deadbolt engages the door’s frame in three locations from top to bottom, operated by a sturdy rack and pinion system hidden inside the
door. Another safety feature of quality steel doors is a rugged heavy
wood lock block. The insulated foam placed in the hollow can provide
insulating values of R-14 and greater.
Exterior steel doors come in many styles and finishes and are commonly fitted with glass inserts and peepholes for viewing. They’re also
available with real natural oak and other veneers permanently bonded
to the steel skin all sandwiched around a core of insulation. The steel
doors with magnetic gaskets along their edges grip like seals on a
refrigerator door give the tightest seal against the weather. For ease of
installation, they’re available with integrated framing systems that
coordinate framing components, sills, door bottoms, corner pads, and
weather stripping as a single packaged unit, completely pre-hung with
hinges. The cost of steel doors is quite competitive with those made of
wood.
Make sure that any steel door you buy is predrilled by the supplier
to accept the door hardware (handles, knobs, and locks) you desire. If
you don’t, it could cost you extra to have it done at the job site because
some carpenters don’t have the right tools to drill this type of door.
Advantages
1. They provide an excellent seal against air infiltration; some have
magnetic seals.
2. They’re well insulated.
3. They’re difficult to force open, cut open, or break through.
4. They’re not affected by moisture and won’t crack, rot, or warp.
5. They’re fire resistant.
6. Plastic decorator panels are available for some steel door models
to provide elaborate and varied finishes.
DOORS
7. They come in 20-gauge, dent-resistant wood-grain finishes that are
stainable to achieve the warm look of wood.
8. Steel doors can be purchased with stained wood, steel, or vinylcoated aluminum.
9. Steel doors are available with fully adjustable oak or vinyl caps to
provide energy-efficient fits.
10. Multiple-blade sweeps (on door bottoms) eliminate drafts.
Disdvantages
1. They come in standard sizes and are not easily adjusted to slightly
uneven openings or odd-sized openings.
EXTERIOR FIBERGLASS AND CARBON DOORS
Factory-finished or stainable fiberglass and carbon doors have
sturdy construction and a foam core that gives them high insulating
values. These doors will hardly shrink or expand with changing seasons, maintaining a tight air and moisture seal that is often further
ensured by the use of magnetic weather stripping with brass-plated
steel trim strips inlaid in the door’s edge. Of the two, carbon
expands or contracts less with temperature changes, making a
tighter seal.
Carbon door skins also require less forming pressure during the
manufacturing process, so the surface remains more porous and able
to take stain very well. Triple-locking mechanisms with heavy-duty
blocks such as those found on better wood and steel doors are also
available on fiberglass and carbon door models.
COMPOSITE PATIO DOORS
Patio doors are typically sliding glass doors framed with steel, aluminum, or wood, or French doors that provide access to a patio, porch,
deck, or garden. The wood frames are frequently clad in vinyl to eliminate the need to repaint or refinish the wood.
Double- or triple-pane glass that has a good insulating value should
be used in these doors, and weather stripping must be included along
the door edges. Design improvements have separated the inner and
outer faces so that the frames will not easily transmit heat or cold.
359
360
HOW TO BUILD IT
Advantages
1. Glass allows a view of the outside surroundings.
2. They require very little maintenance.
3. They’re great if lots of light and sunshine are desired.
Disdvantages
1. They’re easy to force open if proper precautions are not taken.
2. Poorly constructed ones will sweat.
3. When constructed without thermal-type double or better glass, they
have poor insulating value.
4. Even with the better patio doors, the wear and tear caused by the
regular door movement across the sealing material is prone to leaks
in the sealing that will allow air and moisture infiltration.
GENERAL DOOR CONSIDERATIONS
Make sure you check the operation of each door after the doors are
installed. Because doors are used so often, minor imperfections or
operating deficiencies can become very annoying.
See that:
■ All knobs, locks, and deadbolts work properly, without sticking,
and that doorknobs and latches line up with latch inserts. You
shouldn’t have to yank a door closed to latch it, or push downward or upward on the handle to engage the latch. This is especially important for a basement door. If it won’t close securely, a
small child could open it and fall down the stairway.
■ Doors hang level, with hinges that don’t squeak or bind. All
doors should swing freely, without noise or obvious friction.
The door installation must be square, with an even gap between
the door frame from top to bottom.
■ Opened doors should hold their position and not swing closed
or farther open by themselves.
■ Door frame and casing nails should be set below the wood sur-
face and puttied.
DOORS
■ There should be no leaks around the weatherstripping or
thresholds.
■ When choosing interior doors, you can increase the appearance
of interior lighting while making the room look larger by selecting mirrored doors. Interior doors are available having a mirror
built into one side. Mirrors reflect lighting, so the lighting travels around the room farther, illuminating things on its way. At
least one manufacturer offers mirrored doors with framed and
frameless mirrors on doors that swing, slide, and bi-fold open
and closed.
■ At times, we all receive unwanted visitors at our front door.
During summer or winter, heated or cooled air is lost when the
front door is opened so that unrequested solicitors can be spoken with or asked to leave. For safety’s sake, and to limit the
need for opening the door unnecessarily, consider the installation of a wide-angle peephole. Models are available that offer
excellent views of the outside. One unit even projects the view
onto a screen that’s several inches wide.
■ To protect a door’s integrity, install a door stopper that will pro-
tect both the door and its adjacent wall. Look for a model that
does not put pressure on the door itself.
■ For exterior doors, consider a built-in battery-operated burglar
alarm that, when the door is locked, any shaking of the door sets
off an audible alarm for a short time. The alarm sensitivity level
can be adjusted.
➤➤➤➤➤ POINTS TO PONDER
1. When selecting a door, ask yourself if it will operate easily and
reliably, close securely, interfere with the use of space on either
side of itself, retard the spread of fire, deaden sound, and allow
you to see to the other side.
2. A home’s front door is often the first thing a visitor (or potential
buyer) sees. It helps form an impression of the rest of the home,
for good or for worse. In short, the main entrance can make an
impression that adds considerably to a dwelling’s appearance
and even to the home’s value and saleability.
361
362
HOW TO BUILD IT
3. A little extra invested for a unique entrance door that’s more
attractive than those typically found with comparable homes
will be worth it in the short and long run.
4. Storm doors for all outside entrances/exits are a must in cold
climate locations, and also desirable in warmer locations
because they can help conserve cool air, screen out insects, and
provide ventilation.
5. If you’ve ever seen or had a child accidentally run through the
regular glass panel of a storm door, you know why only safety
glass should be used with storm doors.
6. Pocket doors, once popular years ago, are useful in locations
where there is little room to swing a standard hinged door out
of the way due to interference with traffic or the operation of
other doors.
7. For security’s sake, exterior hinged doors must have standard
hinges positioned on the interior side of the door so that the
pins can’t be removed by a potential intruder to gain access.
8. Make sure that all latch mechanisms line up correctly with
their matching plates, so the doors can be positively closed and
won’t accidentally swing open in response to window or fan
drafts or pets or toddlers pushing on them. This is especially
important with bathroom and basement doors.
9. For ease of operation, European-type latch handles provide
greater leverage and a more comfortable grip than do round
doorknobs.
10. Bifold doors are ideal for closets. They allow a maximum opening with minimum extension into the room. Extending the
height of the doors a full 8 feet to the ceiling eliminates the
need for headers and permits full-width shelves and access to
the upper area that would otherwise be lost.
CHAPTER
15
Garages
T
he garage is not often given the attention it deserves by the typical
homeowner. A brief analysis of the situation reveals no sound
reason to skimp when it comes to this important part of a house. To be
sure, many owners don’t realize that a garage costs considerably less
per square foot than the rest of the house: it doesn’t have as much
electrical, plumbing, lighting, or floor or interior wall finishing costs.
Consequently, instead of being stingy with your garage money, you’re
better off building one a little larger than you initially want. It won’t
cost much more (Fig. 15.1).
When you do plan your garage, here are some ideas to keep in
mind:
1. Few garages built today are constructed apart from the house. The
conveniences of initial construction, maintenance, and homeowner traffic patterns of an attached garage far outweigh the disadvantages.
2. However, an attached garage requires safety features not necessary
in detached models. In some locations, the ceiling and wall connecting the garage and house must be plaster, masonry, or some
other fire-retardant material, and the door from the garage to house
must be solid wood or covered with sheet metal.

3. One disadvantage with attached garages is that carbon monoxide
fumes can gather within them and seep into the house’s living
quarters. Carbon monoxide fumes are heavier than air and can
travel into a basement or lower living level if the garage is on that
same level or higher. To prevent this from happening, your building code will state the required stepdown measurement from the
house to the garage. A curb can also be a partial remedy. In any
case, if you plan a house with an attached garage, realize that there
will always be a potential danger with exhaust fumes if a car is
allowed to idle in the garage with the garage door closed.
GARAGES
4. Request a minimum of two electrical wall outlets in the garage, as
well as an outlet or outlets centered above the overhead garage
door(s) so you can put up automatic door openers at a later date if
desired.
5. Besides having at least two overhead lights installed in the main
level of the garage, if there’s a garage attic in your plan, specify a
light fixture there also.
6. Provide adequate ventilation in any garage attic.
7. If you want to heat the garage, have the outer walls as well as those
of adjoining living spaces insulated.
8. Proper flashing should be installed between the garage roof and
the wall of the house, or vice versa, to prevent water seepage there.
9. If the back of a fireplace chimney will protrude into the garage,
make sure you take this into consideration when planning the
garage’s length.
10. To keep out the elements, soil, and energy-wasting summer and
winter temperatures, make certain that the garage car doors will
seal tightly against the floor and sides of their tracks when closed.
11. For appearance’s sake, specify if you desire the trim around the
car doors to have “cut corners” at the top. This can add an interesting flair to a garage for a minimum cost.
12. If you’re having a two-car garage, decide if you’d prefer two separate car doors or a single larger model. Two doors might look more
attractive, but they require two separate door openers and need a
support post in the center, which reduces the opening clearance
that might be wanted for maneuvering a boat trailer in. Such a center post between two doors can also become an expensive obstacle
for inexperienced drivers to crunch into.
13. A single-car garage should be no smaller than 12 feet by 14 feet to
provide enough space for an automobile plus general equipment
such as lawn mowers, snowblowers, ladders, garbage cans, bicycles, and other sports items. A two-car garage should be at least 24
feet by 24 feet to comfortably handle two autos and equipment
storage. The ceiling height in either case should be at least 12 feet,
with plenty of room to install an electric garage door opener.
365
366
HOW TO BUILD IT
14. Have a water faucet installed somewhere inside the garage. The
best place is usually on a common wall with the living quarters of
the home, to avoid winter pipeline freeze. An ideal arrangement is
a utility sink center. A utility sink center will allow you to complete cleanup chores before going into the living areas of the
house. This includes messy tasks such as bathing a pet and washing off fruit, tools, greasy hands, or clothes. A variety of units are
available. An inexpensive one that does a good job is a plastic sink
24 inches wide, 24 inches long, and 12 inches deep.
15. A telephone in the garage offers numerous conveniences. When
you’re working in the garage or yard it will save you from tracking
through the house in dirty clothes, and you can at times grab a call
you’d probably otherwise miss.
16. Having a window or windows (other than in the garage door)
helps increase illumination and air circulation. From a safety
standpoint, that means you can see more of what you’re doing,
and you can get rid of fumes from a car’s exhaust. An awning window is a good choice because it can be cracked open for ventilation even in times of inclement weather.
17. Depending on your garage’s design, you may want to consider one
or more skylights for additional natural light and ventilation. Skylights can also help dissipate heat during summer, when having a
cool garage will help prevent the rest of the house from becoming
uncomfortable or needing air conditioning. Electric venting skylights are available to be operated from either a remote control or
a convenient fixed location near the entrance door to the garage
from the house. Some models even feature rain sensors that automatically cause the window to close at the first sign of rain or
other moisture. A model that fits perfectly between the trusses or
other roof supports should be selected.
In some climates, not enough heat from the home radiates into the
garage, especially during winter. A heat vent or wall heater installed in the
garage is frequently the answer. Either one offers the following benefits:
■ Snow and ice will melt/dry off cars and the garage floor.
■
Fluids and foods stored in the garage will not freeze.
GARAGES
■
Working on a car, snowblower, and any other project can be
done in relative comfort.
■
You won’t have to scrape ice and frost off your car windows in
the morning.
GARAGE DOORS
Since a home’s garage car door often makes up a major part of the
dwelling’s structure and curb appeal, it’s important to select a door
that will contribute as much beauty, security, and insulation as possible. That means avoiding marginal-quality units that eventually may
shake, rattle, warp, stick, and deteriorate, and selecting only quality
garage door and opener systems.
Modern car doors on garages either swing or roll up out of the way.
Old-fashioned sliding bypass types and hinged garage doors are much
less practical. The typical single garage car door is 7 feet high and 9
feet wide, while a double garage car door is the same height and at
least twice as wide (Fig. 15.2). Some doors have reinforced, highimpact nylon rollers with solid steel shafts. These rollers enable the
door to glide easily, smoothly, and quietly.
Insulation values can range from about R-6 to R-7. Windows in the
door will typically lower the overall insulating value. Naturally, favor
doors with higher R-values. Also, review the various decorative window design options available with doors you are considering. There
are frosted and beveled panes and assorted decorative glass inserts.
All, however, should be the shatter-resistant type.
In general, the better units feature strong warranties on the doors
and their openers.
Garage doors are constructed in a variety of materials. Below are
the pros and cons of each type of construction.
WOOD DOOR CONSTRUCTION
Advantages
1. The wood can be painted or stained to a desired color or finish.
2. Intricately carved or rough sawn panels are available to suit a
home’s exterior decor.

3. Wood doors can be precision-cut from solid 3⁄4-inch redwood or
hemlock, offering a beautiful natural finish when stained and covered with a clear-coat protectant.
Disadvantages
1. Will periodically need to be repainted or refinished.
2. It doesn’t clean well.
3. It’s capable of warping and rotting.
FIBERGLASS DOOR CONSTRUCTION
Advantages
1. It’s lightweight.
2. Doesn’t need to be painted or stained.
GARAGES
3. Can be easily cleaned.
4. Resistant to salt, air corrosion, and to rusting and warping from
exposure to moisture.
5. Lightweight and easy to lift without an automatic opener.
6. Is relatively inexpensive and requires little maintenance.
Disadvantages
1. Low strength.
2. Some fiberglass doors come with minimal insulation.
3. Not as strong or secure as steel doors.
STEEL DOOR CONSTRUCTION
Steel-door “sandwich” construction is by far the most popular with
builders and homeowners. It consists of two outer steel “skins” sandwiched or pressure bonded around a rigid polyurethane foam, polystyrene core, or similar panelized material. Panelized insulation
materials offer added strength plus predictable heat and consistent
noise insulation qualities, while injected foam insulation may decompose and develop cavities. In short, this method of construction results
in high-strength, dent-resistant, well-insulated, attractive doors. Additional desirable steel door features include the following:
■ Heavy gauge high-tensile steel skins (26- or 24-gauge) with deep
embossing to help resist denting.
■ The steel skin “layering” can include zinc/steel plating, hot-
dipped galvanizing, primer coatings, and exterior/interior finish coatings to resist rust formation. Paint colors are often white,
tan, brown, almond, or others. Some doors feature wood-grain
outside finishes and textured inside coatings that simply wipe
clean, like those of a kitchen range or refrigerator.
■ Durable heavy-duty hinges that are galvanized and coated.
■ Heavy-duty steel backup plates laminated under the inside steel
skin to support each hinge.
■ Painted galvanized steel end stiles to give hinges and rollers
extra support and a clean interior appearance.
369
370
HOW TO BUILD IT
■ Heavy-duty steel step-plates, inside and out, which help make
the door easy and safe to close without the automatic opener.
■ Steel door panels that are mechanically interlocked along their
entire length for additional strength.
■ Steel door panel joints should have seals to prevent wind, rain,
and snow from entering between sections. There are two popular types of panel seals—compression and tongue and groove
(Fig. 15.3). The compression type has an excellent seal, but
tends to wear over time. The tongue-and-groove panel seal is
effective and almost maintenance-free.
Advantages
1. With exterior skins of at least 26-gauge steel, they have good
strength and durability.
2. The insulation value, given a thickness of 2 inches of material, is
about four times that offered by a conventional wood door.
F I G U R E 15 . 3

GARAGES
371
3. Painting maintenance will be minimal as long as the exterior and
interior door skins are precoated with an epoxy primer plus a topcoat of polyester white, brown, or other color of baked enamel.
Disadvantages
1. They’re heavy.
2. If scratched, touch-ups are difficult to complete.
3. Cleaning is often difficult.
ALUMINUM DOOR CONSTRUCTION
Advantages
1. Light in weight.
2. Painting and maintenance needs are minimal, given primer and
enamel precoatings similar to those available on steel doors.
Disadvantages
1. Some models are lacking in strength.
2. Scratch touch-ups are difficult to make.
3. Cleaning can be difficult.
Swing-Up Doors
These are less expensive than roll-up
doors. They can be made on the building
site from the same materials used for the
house’s siding. Often, though, swing-up
doors consist of thin sheets of exterior plywood that are easy to work with and light
enough for the owners to open with little
bother. The drawbacks to this type of door
are that it’s so lightly constructed it often
has problems operating on its tracks, it can
warp easily, it’s not very energy efficient,
and it’s not as attractive as roll-up doors
(Fig. 15.4).
F I G U R E 15 . 4

HOW TO BUILD IT
Roll-Up Doors
Roll-up doors are the most popular and practical garage car doors
available. They come in wood, steel, aluminum, fiberglass, plastic,
masonite, and composite models. Insulated garage doors made of plastic, aluminum, or steel having fiberglass insulation inside are terrific
for saving energy. The plastic doors are also maintenance-free, with
the door’s color an integral part of its makeup so it never needs resurfacing. Any roll-up door should be trimmed on the bottom with an
astragal (rubber) strip to ensure a tight seal with the floor.
Specify the type of roll-up door propelled by torsion springs for
operating safety and ease. All roll-up doors can be efficiently connected to automatic door openers.
Garage Door Features
Perimeter weather sealing with jamb and header seals along the
exterior sides and top of the door is critical. To prevent air infiltration
the door should be equipped with the following factory-installed seals
(Fig. 15.5):
■ Between each section joint
■
Self-adjusting jamb seals on the end stiles
■
Top section header seal
■
Adjustable U-shaped bottom rubber or astragal seal with the
ability to conform with irregular floors to effectively seal out the
elements
The bottom weather seal retainer should be made of aluminum or
other rustproof sturdy design; its thickness will likely affect the door’s
durability. At least 2 inches of insulation, pressure bonded between
the sheets of steel or other material, reduces energy loss and improves
noise reduction.
Tongue and groove section joints provide excellent weather sealing.
Look for a door model with a pinch-resistant joint design that helps prevent fingers from getting caught in the door panel joints. A full plastic
thermal break will reduce metal-to-metal contact between the interior
and exterior of the door’s surface while adding to insulating efficiency.
Garage door windows should be watertight and at least double-glazed.
GARAGES
F I G U R E 15 . 5

Torsion springs should be computer-calibrated to match your door
load. The springs should be made from oil-tempered wire and must be
mounted on a continuous cross-header tube or shaft that’s appropriate
to the door’s torque load. Torsion springs mounted without a tube or
shaft are dangerous because if they snap unexpectedly they’ll whip
through the air with a powerful force.
Automatic Door Openers
It’s nice to come home late at night in a thundering rainstorm or
blizzard and push a tiny button from within the car so that your garage
door raises open for you, like magic. For the sake of convenience and
safety, automatic garage door openers are relatively inexpensive and
reliable contraptions.
373

HOW TO BUILD IT
SAFETY >>>NOTE
GARAGE CAR DOORS
Some garage car doors feature “safe” hinges designed to reduce the
chances of fingers getting pinched between sections of a closing door.
Finger shields “hide” and restrict access to section joints on the door’s
outer side. Other brands offer pinch-resistant designs where the closing
sections actually push fingers away from the section panel joints as the
door closes. The parts of some of these pinch-preventers are made from
the same prepainted steel as the door panels themselves so they blend
in with the rest of the door face.
Advantages
1. Convenience. You never have to get in/out of your car to open/close
the garage door, especially in bad weather. An inside wall button
lets you open and close the door while standing at the garage man
door from the house.
2. Safety. A built-in lamp brightens the way as you head into the
garage, or out of it.
3. Security. The opener itself acts as a garage lock, making it difficult
for anyone to jimmy open the garage door. Plus, the door is automatically locked when closed.
4. Weather protection. The opener’s shock absorbing spring(s) allow the
door to close tightly against the floor, assuring a good weather seal.
Check for the following features:
1. There should be an easy disconnect pull cord for manual operation in case of a power failure or other emergency. It should automatically reconnect when the radio control or wall push button is
pressed after the power is restored.
2. A 1⁄3-horsepower motor will handle a single-car door, but a 1⁄2-horsepower unit is recommended for double doors.
3. There should be separate up and down door travel limit nuts that
are easy to adjust for fine tuning of the desired open and closed
positions.
GARAGES
4. A heavy-gauge metal cover should protect the inner workings. It
should have a maintenance-free decorative surface.
5. There should be safety switches that are obstruction sensitive.
They’ll make the door automatically reverse itself if it contacts any
object.
6. An electric eye. Even if you aren’t planning to have children or
pets, include an electric eye to supplement the obstruction
switches. It will stop a descending door and send it back up when
a child or animal passes through the beam.
7. A keyless entry mounted to the garage overhead door jamb that
allows access from the outside via a private (and changeable) security keypad code, thus eliminating the need to leave the garage
door open for long periods just because someone will be arriving
later and needs access (such as children or other relatives). This
also comes in handy when there aren’t enough door remote units
to cover all of the family vehicles.
8. Plastic strap track drives, belt drives, and worm screw drives are
quieter than chain drive openers.
9. Remote-control coding. So the code can be changed by flipping
small switches in the remote to any up/down configuration you
desire.
10. A high-impact plastic light cover for the lamp that turns on automatically for five minutes when the door is either being opened or
closed.
11. Consider an opener with two-socket lighting. This allows for two
light bulbs to do the illumination. When one bulb burns out, the
other will continue to provide some light, providing time for the
bad bulb to be changed. This is particularly important for someone with limited mobility who needs help changing out an overhead bulb.
12. A vacation switch. The switch renders the opener deaf to all radio
signals, including those from its own remote, while you’re gone.
13. Some units come with a lighted keyless four-code entry pad that
installs unobtrusively on the outer door frame. It has its own flipup weather protection cover and allows the homeowner to press
in the correct code from the outside to open the door.
375
376
HOW TO BUILD IT
12. Fixed door opener codes can lead to thieves stealing or cracking
the code with sophisticated code-cracking devices; then, while
you are away, the thieves may open the garage door to survey what
they could take. Even if nothing appeals to them, they may leave
the door up during the middle of winter as they disappear, allowing cold air in and leaving your garage open for further vandalism.
To defeat these thieves, some keyless entry pad systems feature
anti-burglary coding mechanisms that automatically change the
access code to one of billions of new codes selected each time the
remote control unit is activated.
15. Consider a unit with a soft start/stop that prevents jerking when
starting or stopping. Again, make sure that the opener you select
will reverse itself automatically if it encounters any obstacles
(such as a small child) while closing toward the garage floor. Also
arrange for the control buttons to be positioned high enough so
children can’t reach them. This is especially important for the buttons near the inside garage man door to the house. Children will
sometimes push a control button to close the door then attempt to
dash through the opening before the door is fully lowered.
16. Units are available that operate off a direct current (DC) motor
instead of with a standard alternating current (AC) motor. The DC
motor can operate on less energy, will provide a soft start and stop
feature for smooth operation, less noise, reduced door wear, and
greater reliability.
17. A polymer-lined rail reduces metal-to-metal contact between
movable parts for less resistance and noise during operation.
18. Units are available with a light control having an energy-saver
shutoff. There’s also a motion-detecting control panel that will
turn the garage door opener lights on when someone enters a dark
garage from inside the home. A timer should automatically shut
off the same lights after a few minutes. Another option is a multifunction remote control that will turn on the opener’s lights independently of the garage door operation, and even activate or
deactivate house lights. This is helpful when a person must enter
through the small door and wants the lights on in advance.
19. Consider the feature of having a red light inside the kitchen or other
room that goes on whenever the garage car door is in a raised position.
That may save the door from being accidentally left open all night.
GARAGES
Garage Door Screens
If included, this handy feature offers the pleasure of using your
garage during warm-weather days and evenings for sitting, socializing
and partying without being annoyed by insects or dampened by rain.
Man Doors
A man door entrance to the garage should be included to permit
access into the garage from outdoors without having to raise the garage
overhead door. The best man doors are steel-covered. They’re strong,
burglar-resistant, and fare well against the weather. As with all other
outer man doors, garage entrances should be insulated with weather
stripping. Depending on your lot, if the back of the garage faces the
backyard you might consider having a second man door installed there.
SAFETY >>>NOTE
GARAGE DOOR OPENERS
Remember, a photo-eye positioned near the floor across the garage
door’s plane of travel must not be the automatic door opener’s only or
main method of preventing injury. Although the photo-eye beam mechanism—when working correctly—will prevent someone from being struck
and will reverse the door’s travel, it does not react upon the door’s edge
striking something on its way down. Indeed, sunlight, rain, or snow can
make the photo eye malfunction, as can collections of dirt or other
debris on the lens, and even a simple bump of the eye by a child’s foot
or basketball can disable the beam from proper operation. Instead, the
unit’s main safeguard must be a sensor in the opener’s drive mechanism, set so the door will automatically and immediately stop and
reverse its travel upon encountering a change in pressure or resistance
(such as the presence of a child’s head or arm) when the bottom edge
of the door strikes the same on its way down.

Some manufacturers offer a wall control inside the garage with an illuminated open/close button in case the door must be opened in the dark.

HOW TO BUILD IT
GARAGE FLOORS
The following points should be considered to ensure a trouble-free
garage floor:
1. It should have a 4-inch gravel base covered by a sheet of polyethylene or similar moisture barrier. Drainpipes should be laid under the
gravel, and the gravel should be tamped before the concrete floor is
poured.

cables. If the rag catches or tears, have the cables
inspected by a professional.
Inspect the garage door springs, rollers, pulleys, and other
hardware for signs of wear. Make sure nuts and bolts are
tight. If any component is broken, contact a professional for
repairs and avoid using the door until they’re completed.
Per the manufacturer’s instructions, periodically lubricate
the door rollers, bearings, hinges, and drive mechanism.
Test the emergency release used for power outages, then
test the balance of the door to see if the springs are properly adjusted. Follow the manufacturer’s guidelines, or
close the door and disconnect the automatic operator. You
should then be able to lift the door waist high with relative ease. The door should stay open in that position by
itself. If it doesn’t, the door spring tension should be
adjusted by the door company repair person until it does.
Test the reversing features on the opener monthly by seeing
if the photo-eye works and by placing a 2- by 4-inch block
of wood on the floor to obstruct the door to see if it will
reverse direction, as it should. If either of these safety features fails, disconnect the door opener until it’s repaired.
GARAGES
2. If no garage floor drains will be installed, the garage floor should be
poured so it begins about 1⁄2 inch above the driveway’s surface then
slopes up to about 2 inches toward the back of the garage.
3. If possible, include floor drains, one for each car space. Naturally
the floor should be sloped toward the drains to prevent any standing water.
4. To support the edges of the garage floor where the fill around the
footer might settle, specify 6- by 6-inch reinforcement wire to be
used throughout the entire floor.
5. The concrete should be poured at least 4 inches thick.
6. The garage (and basement) floor should be steel-troweled to
achieve a smooth finish. This is a time-consuming task that requires
going over the surface with a trowel many times during an 8-hour
period or until the surface hardens.
7. The part of the garage floor that sticks out past the garage door—
normally about 6 inches—should taper away from the door down
toward the driveway, ending 1⁄2 to 1 inch higher than the driveway
surface. By tapering it down toward the driveway, rainwater and
melting snow will not drain into the garage. Keeping the floor
slightly elevated prevents water from backing up into the garage
from the driveway.
8. Before parking cars on a new garage floor, the floor should be
cleaned with a solution of muriatic acid, then coated with two or
three applications of a clear sealer. The sealer improves the floor’s
appearance by preventing oils, grease, and dirt from staining the
concrete and by making the floor a lot easier to clean. It will also
prevent cement/concrete dust from rising and will help water flow
more quickly toward the drains.
GARAGE ATTIC STORAGE
The garage attic, even when trusses are running through it, can be
used to store off-season equipment of all types, including holiday decorations, lawn furniture, spare tires, kids’ swimming pools, bicycles,
and gardening supplies. To make this space accessible, cover or “finish” the attic floor and specify a set of pulldown steps. Folding or roll-
379
380
HOW TO BUILD IT
down type stairways (Fig. 15.6) are in most cases the best option. At
the same time, with attic space in the garage quite high off the garage
concrete floor, these types of stairways are far safer than using conventional stepladders.
Make sure whichever model you choose has handrail(s). Also,
when closed, the unit should latch securely against a rubber seal to
prevent drafts and insects from entering the attic.
There should be adequate lighting installed in the garage attic so
you can see and move freely about in a safe manner. The switch for the
light should ideally be located on a wall in the garage so you can turn
it on before climbing the stairs. A less-desirable alternative is a pull
string you can grab as you reach the top of the attic stairs.
If it applies to your location, avoid the use of fluorescent bulbs,
which take too long to activate in cold temperatures. Also make sure
F I G U R E 15 . 6
Folding pulldown stairway.
GARAGES
exposed bulbs are not situated where they’ll be easily bumped into
and broken.
An important consideration for a garage attic is ventilation. A thermostatically controlled ventilation fan is an excellent choice to help
remove excess summer heat and car exhaust fumes. Such a system will
also prevent dampness and mold problems. Ridge, roof, gable, and soffitt ventilation can also be employed with satisfactory results.
Electrical outlets should be installed throughout the attic so that
you can plug in tools or a vacuum cleaner.
GARAGE STORAGE
In years past, there was a time when garages fit the automobiles for
which they were built like a glove. Now garages are erected not only to
hold cars, but to shelter a wide variety of other work, maintenance,
and leisure-time items.
Consider the following ideas when planning your garage storage
space:
1. Provide enough space to store lawn mowers, snow blowers, bicycles, and other bulky objects along a side wall, and a place to keep
even larger items such as garden tractors or small boats along the
back wall.
2. No matter what size garage you plan, many cubic feet of relatively
inactive storage space can be salvaged by building one or more
shelves 24 to 30 inches deep around the two sides and the back of
the garage about 6 feet above the floor, attached by brackets fixed to
the walls. This will accommodate the storage of spray cans, garden
tools, box of rags, auto parts and supplies, and so on.
3. A huge rack for storing screens, oars, water skis, and other long articles can be hung from the ceiling over each car bay. If built over a
“walking area” at the sides or in front of where a car is stored, the
rack should clear the floor by at least 7 feet, but where it hangs over
the car it can be dropped to within 6 feet of the floor because it isn’t
over a highly traveled pedestrian zone.
4. The more you can keep items elevated off the floor, the easier and
faster you’ll be able to clean out the garage.
381
382
HOW TO BUILD IT
5. You’ll find it handy to leave one wall with the framing studs and
planks exposed—not covered with plaster or drywall board. This
permits you to attach large sheets of Peg-Board directly to the studs
and will provide an airspace to arrange hanging pegs into the PegBoard itself. Peg-Board is ideal for hanging all sorts of hand tools,
garden tools, hoses, and many other items. If Peg-Board will be
secured to finished walls, you must leave an airspace behind it
using 2- by 2-inch studs to establish a gap.
6. Heavy garden tools and items such as hand mowers, empty lawn
rollers, and long wooden extension ladders can be hung from 4-

GARAGES
inch boards nailed across open studs when steel brackets are fastened to the top edges of the 4-inch boards.
7. A lockable tool/equipment cabinet keeps small items and tools
organized and extra secure.
8. On the bottom of the exposed stud walls, and below areas having
Peg-Board, you can build 12-inch shelf inserts between the studs on
top of the block, at an elevation approximately 12 inches above the
floor (Fig. 15.7). It will work well for storing wash pails, step stools,
jack stands, bags of seed, fertilizer, and so on.
GARAGE POSITIONING
This subject is covered in the chapter on house orientation and
positioning, but in a nutshell: the garage must fit on the lot without
encroaching on an adjacent site. It should also conform to the slope of
your lot. For instance, when a garage is located on a downward side
sloping lot, instead of completely lowering the garage to meet the natural lot line or placing load after load of fill dirt to raise the lot level,
it’s best to reach a compromise between the two solutions.
Position a garage to reduce energy loads. In cold-climate areas
garages should be located on a northern part of the house, if possible.
In hot-climate areas, a garage is best suited on the east or west side of
the home to help reduce heat gain.
➤➤➤➤➤ POINTS TO PONDER
1. A garage costs considerably less per square foot than the rest of
the house costs. Instead of planning a garage that’s just large
enough for your needs, go a few steps further. It won’t cost
much more.
2. A garage can be positioned as a buffer between cold prevailing
winds and home living spaces, or on the east or west side of the
dwelling to help shade interior living areas, depending on your
location and climate.
3. If you plan to heat the garage, have the outer walls, as well as
those of adjoining living spaces, insulated. If you insulate, consider that when a warmed car is pulled into the garage after a

drive, heat radiating from the parked vehicle will be retained
longer within the garage, and will even help insulate the
adjoining part of the house.
Have a water faucet or utility sink center installed somewhere
on a common wall with the living quarters of the home.
Install a garage floor drain, or better yet, a strip drain (a rectangular lengthwise concrete drain covered with pieces of removable grating for cleaning mud or debris) so the floor can be
hosed down when needed throughout the winter.
A telephone located in the garage provides numerous conveniences. Otherwise, the opening and closing of the house door
will waste energy as the home’s heated or cooled air is lost.
Also consider installing a cable television outlet there, for
watching favorite programs while waxing a car or pursuing various hobbies and housework activities.
Automatic garage door openers must have automatic reverse
safety features and should also have an electric-eye beam
which stops a door’s downward travel when someone or something crosses the floor in the door’s path.
It usually makes sense to have a garage attic that can be
accessed by a set of pull-down stairs.
Garage attics should have lighting, a sturdy floor, and adequate
ventilation.
Plan garage shelves, Peg-Boards, racks, and hangers with the
goal of keeping items in the garage stored off the floor, so the
floor remains uncluttered and easy to be kept clean.
Fluorescent lighting will allow you to spend long periods of
time performing various activities in the garage without receiving a high electricity bill.
Sunlight Tubes installed in the garage can help provide an
inexpensive source of natural illumination.
To maximize lighting efficiency, have the walls painted white
or another bright, light color or shade.
CHAPTER
16
Fireplaces
T
he first fireplaces were logical extensions of an open campfire—
functional features that were designed to provide heat,
illumination, and a way to cook foods in early dwellings. They were
originally a necessity in all but the warmest climates and supplied
homeowners with basic needs for centuries.
Then, rather quickly, other mechanisms were invented that more
efficiently heated our houses, illuminated our rooms, and cooked our
foods. Consequently, fireplaces lost some of their functional value and
became more decorative options than necessities. They still, however,
remained a part of our houses for the atmosphere they created and the
warmth that homeowners appreciated on cold winter evenings. But
once the energy crunch hit, fireplaces were accused of being the
energy-wasters they really were, and fell further out of favor.
Not to be upstaged, hundreds of large and small companies set out
to modify the standard fireplace into units which, through various
add-on tubes, gadgets, and heat exchangers, would burn fuel much
more efficiently.
So today’s fireplaces can be divided into two main types: those
used primarily to heat a room, area, or entire house; and those used
primarily as decoration or novelty. Even with continuing concerns for
energy usage, the latter models—the fireplaces installed for decoration
and atmosphere—are still the most popular. They’re included in mod-
385

HOW TO BUILD IT
ern homes because of what they add to a room, in ways that excite our
senses of sight, sound, and smell. They’re a bit of the past to which we
still cling.
Any fireplace should at least do five things:
■ Permit combustion of fuel.
■ Exhaust the by-products of combustion from the house.
■ Deliver as much heat as possible into the house.
■ Function safely.
■ Be located so people sitting in all areas of a room can enjoy it. In
a long, narrow room, for example, it’s better to plan a fireplace
on one of the long side walls than on a short end wall. Because
people tend to cluster around a fireplace, if it’s located at one of
the short walls in an end of a long room, the opposite end of the
room (without a fireplace) would likely go completely unused.
Advantages
1. They can provide additional heat.
2. They can provide all the necessary heat in mild-climate locations.
3. They enhance the appearance and comfort of any room in any
house in any climate.
4. They provide a traditionally romantic and reassuring atmosphere.
5. They can burn as fuel certain combustible materials that would otherwise be wasted, such as coke, briquettes, and scrap lumber.
Disadvantages
1. A major concern with a typical fireplace is that it uses substantially more air than needed for combustion. The room air used for
fireplace combustion has already been heated by the primary heating system, and much of it is ultimately lost up the chimney.
Rather than assisting the primary system in its heating function,
the fireplace can interfere with its operation and usually increases
the workload of the primary system. As much as 80 percent of the
heat produced by a wood fireplace can dissipate up and out of the
FIREPLACES
chimney. To address this concept further, you can review the Fireplace Energy Efficiency Points toward the end of this chapter.
2. A fireplace heats by radiation only. Much of the air that comes into
contact with the hottest surface of the fireplace ends up outdoors.
3. Some warm air from the house will go up the chimney even when
a fire is not lit and the damper is closed.
4. Because brick and stone are poor insulators, a fireplace and chimney can create a thermal opening in the wall of a dwelling if
located somewhere in the building’s outer shell.
5. A fireplace adds to the cost of a new house.
6. When positioned within a building, a fireplace occupies valuable
floor and wall space.
7. When positioned in an exterior wall, a fireplace can occupy scarce
land.
8. A fireplace requires periodic maintenance and occasionally the
services of professional chimney cleaners.
9. Fireplaces can be messy. Storage space for wood and other fuel is
needed, and so are places to keep dirty fireplace tools such as pokers, tongs, and shovels.
10. Fireplaces can be dangerous when incorrectly built, installed, or
used. They can be hazardous when small children have free rein
throughout the house.
TYPES OF FIREPLACES
With the development of modern manufacturing processes, materials other than traditional stone and brick have been made available for
fireplace construction. Today there are numerous fireplace designs
that come ready-made or can be custom-built to suit any application.
Masonry Fireplaces
These are the original models that are still popular today. They consist of a stone or brick exterior having a lining of firebrick—a brick that
can stand high temperatures encountered when wood or other fuels
are burned. Of course, built into the masonry are various operating
387
388
HOW TO BUILD IT
accessories such as grates to hold the wood while it’s being burned and
dampers to regulate the amount of airflow through the chimney passages (Fig. 16.1).
There are several basic masonry fireplace designs, including fireplaces with a single opening constructed against a single wall (the
most popular); fireplaces constructed into a wall that divides two
rooms so the fireplace has two openings, one per each of the back-toback rooms; fireplaces built into an outside corner, open to two sides;
and even circular fireplaces of brick and
stone having sheet metal chimneys suspended from the ceiling that flare out over
the round firebox like an inverted funnel.
Because these masonry units must be
built from scratch on the building site, the
labor construction costs of masonry fireplaces are high. Once a masonry fireplace
is up, however, its maintenance expenses
and efforts are minimal. The beauty, durability, and reputation of its brick or
stonework can enhance the overall
appearance of a house’s interior and exterior and will increase the home’s saleability and value.
F I G U R E 1 6 .1
Stone generally costs more than brick

and requires a higher degree of skill on the
mason’s part. If you opt for an all masonry fireplace, make sure that
whoever will be putting it up has had experience completing others as
well. There are many tricky steps to masonry fireplace construction,
and unless they’re all done exactly right, they can cause serious structural and safety defects that might appear years later. All-masonry fireplaces, because of their weight, require at least an 8-inch-thick
concrete footer for adequate support.
Masonry and Steel Box Fireplaces
This type is similar to the all-masonry fireplace except that the firebox, or where the fuel is burned, is prefabricated of steel instead of
being constructed from firebrick. The rest of the fireplace is all
masonry. Masonry and steel box fireplaces are less costly than all
FIREPLACES
masonry units, and they still retain a handsome appearance and lowmaintenance characteristics (Fig. 16.2).
Circulating Fireplaces
A typical circulating fireplace consists of a specially designed prefabricated steel shell with firebox and damper. It greatly simplifies
construction because all a mason has to do is build the foundation and
hearth, set the prefabricated fireplace shell on the hearth, and lay finishing bricks or stones up around the shell. The shape and approximate exterior dimensions of the fireplace are already determined.
The prefabricated shell more than makes up for its restricted
authenticity with increased efficiency. The real advantage of a circu-
FIGURE 16.2
A masonry and steel box fireplace with circulator vents.
389
390
HOW TO BUILD IT
lating fireplace is that it heats not only by radiation (as a conventional
fireplace does) but also by circulating heated air directly into a room
or adjacent area. As a result, it provides almost twice the heat output
of a conventional fireplace.
The walls of most prefabricated circulating fireplaces consist of
two layers of steel separated by an airspace. Cool air enters the airspace through grilles installed at the floorline next to the fireplace. As
air passes through the bottom grilles and moves between the hot layers
of steel it gets heated and then expelled through other grilles installed
near the top of the firebox or high in the wall. To encourage constant
air movement and an even amount of heat,
manufacturers offer air inlets containing
electric fans. Fans can also be used with
the warm-air outlets placed in adjacent
rooms. The chimney may be of conventional masonry construction or made of
prefabricated steel.
Prefabricated Built-In Fireplaces
FIGURE 16.3
A prefabricated fireplace.
This type of fireplace not only reduces
construction costs but makes it possible to
install a traditional design almost anywhere in an existing house. The prefab
built-in fireplace consists of a steel firebox
complete with hearth, damper, and a prefabricated chimney as well. Prefabricated
built-in fireplaces are made with either
one opening in the front, or with one front
and one side opening. Most are constructed with close clearances. The manufacturer should detail the necessary
clearances and proper floor construction
required. Choose a unit that bears the UL
label, and check what clearances your
building code specifies (Fig. 16.3).
Another advantage to the prefabs is that
they don’t weigh much, so there’s no need
to place them on an elaborate and expen-
FIREPLACES
391
sive masonry foundation. Instead, they can be set directly on a noncombustible floor, and a fire-resistant forehearth can be integrated into
the finished flooring directly in front of the fireplace’s main opening.
Freestanding Fireplaces
Freestanding fireplaces are the least-expensive fireplaces and the
easiest to install. All it takes to erect one is to set it in position and run
a flue through the roof or the nearest exterior wall. Freestanding units
are usually made of steel or cast iron and come in a variety of designs
and shapes—round, square, hexagonal, egg, even triangular. They’re
typically finished in bright porcelains or enamels of red, green, yellow,
black, white, and other tones. They’re modern-looking but give off
plenty of old-fashioned heat because the sheet metal chimney, in addition to the firebox, also gives off radiant heat directly into the room
(Fig. 16.4).
These fireplaces can be placed right against unpainted masonry
walls, but if a wall is constructed or surfaced with combustible materials, a clearance of several inches is needed behind
them and even a greater safety margin is
required on the sides.
Woodburning Stove Fireplaces
To someone looking for more heat than
glamour, a wood- or coal-burning stove is a
good choice. Made of either steel or cast iron,
freestanding stoves can provide over 90 percent of the available heat from wood or coal
combustion. And because they’re not constructed at the building site, they’ll definitely
keep installation costs low. Another plus is
that many models have doors that can be
swung open so all the pleasures of an open
fire can be enjoyed (Figs. 16.5 and 16.6).
When strapped for funds, a home buyer
can elect to install a freestanding woodburning stove after the house is constructed, without much trouble.
FIGURE 16.4
A freestanding fireplace.
392
HOW TO BUILD IT
Like freestanding fireplaces, stoves
must be set out from combustible walls,
and although most of them stand on legs,
they should be centered on a noncombustible pad of some kind.
FIREPLACE DESIGN
Fireplace efficiency depends largely on
proper design (Fig. 16.7). Here are some
important considerations to review if
you’re thinking about including one or
more fireplaces in your house:
FIGURE 16.5
A Franklin wood stove.
1. A common but inefficient way to
include a fireplace in a home is to
have it built so it employs a chimney
at a side or end of a house where three
sides (the back and two sides) of the
chimney are exposed to the weather
(Fig. 16.8). As mentioned in the chapter on insulation, brick and stone are
of limited insulating value. They’ll
lose much more heat to the outdoors
than they’ll save for the indoors.
2. Don’t settle for a fireplace with a large
throat and a flue without an adjustable
damper. An adjustable damper will
limit the amount of warm air lost up
the chimney to only that necessary to
remove the smoke.
FIGURE 16.6
A wood stove.
3. The best place for a fireplace to be
located is away from outside walls, so
most of the heat stored in its brick,
stone, or metal parts is eventually
delivered into the house.
4. A low chimney is a dangerous design
feature.
FIREPLACES
393
5. The most efficient fireplaces follow
established guidelines, mathematical
relationships between the firebox,
opening, throat diameter, and flue
diameter dimensions. If the front
opening is proportionally too large,
the draft will be poor. A cheap way to
decrease the acceptable size of the
opening would be to raise the hearth,
but because a fireplace requires a sizeable draft, savings on energy expenses
in this manner would be insignificant—and very often negative. You
don’t have to actually know what all
the technical points are before you
plan a fireplace, but you should be
able to throw out a few ideas so your
builder thinks that he’s dealing with
someone who understands and will
accept only letter-perfect work.
Even though fireplace dimensions
FIGURE 16.7
vary tremendously, as a general rule,
the height of the opening should be Cross section of conventional fireplace design.
about three-quarter of the width, and
the depth of the firebox should be twothird to three-quarter of the opening height. For openings up to 6
feet wide, the height should usually not exceed 31⁄2 feet; 4 feet is a
good maximum for fireplaces over 6 feet wide. The average fireplace has an opening 30 to 40 inches wide and 30 inches high. The
depth is between 18 and 24 inches. A typical fireplace facing will
be 6 feet wide all the way from floor to ceiling.
6. A fireplace should be more or less in scale with the room it will be
located in. As a rule of thumb, there should be 5 square inches of
fireplace opening for every square foot of floor area.
7. Each fireplace should have its own flue, and it’s not a sound idea
to vent any other heating unit, such as a furnace, into a fireplace
flue.
394
HOW TO BUILD IT
8. Glass doors will eliminate lazy drafts
and reduce smoking, plus they’re
good safety features to have.
9. If natural gas is available in your area,
it’s smart to include a gas starter in a
fireplace, for convenience. Make sure
an isolation valve is included on the
gas line to the starter in case eventual
repairs or maintenance tasks are
needed.
10. To operate safely and efficiently, a
fireplace should be positioned level to
the floor.
FIGURE 16.8
A three-sided fireplace chimney exposure.
WHERE TO LOCATE THE FIREPLACE
Keep in mind that once you decide
where a typical fireplace will be positioned, and once it’s installed,
you won’t want to move it to somewhere else in the house.
Whenever possible, outside wall locations should be avoided. Why
heat the outdoors? The heat loss from a placement along an outside
wall is nearly 25 percent. A chimney that’s exposed to the weather
along its entire length on one or more sides is bound to cool off quickly
when the fire is low. Then, when the fire is rekindled, the products of
combustion must try to force their way out of a chimney filled with
dense, cooled gases. In contrast, heat that escapes through the chimney walls from an inside wall fireplace will help warm the house or at
the very least the garage (Fig. 16.9).
By locating a fireplace on any inside wall, especially the wall separating the garage from the living areas, the part of the fireplace and
chimney facing the garage does not need a facing of finished brick or
stone. Thus, by locating a fireplace in the way most favorable for
energy savings, material and installation costs can also be lowered.
There should be ample room around a fireplace for furniture. But
the furniture placement shouldn’t interfere with traffic in and through
the room, and it shouldn’t be situated closer than 6 feet away from the
fireplace front opening. Chairs and sofas positioned closer than 6 feet
FIREPLACES

will likely make occupants uncomfortably warm no matter what the
outdoors temperatures are.
FIREPLACE SUPPORT
A masonry chimney is usually the heaviest part of a house. It must
rest on a solid foundation to prevent settlement. Concrete footers are
recommended. They must be designed to distribute the load over an
area wide enough to avoid exceeding the safe load-bearing capacity of
the soil. They should extend at least 12 inches beyond the chimney on
all sides, and be at least 8 inches thick for single-story houses and 12
inches thick for two-story houses with basements. If there is no basement, the footers for an exterior wall chimney should be poured on
solid ground below the frostline.
CHIMNEYS
Stone and brick fireplace chimneys can be dominating features no
matter whether they’re located at the exterior of a home, or the interior.
396
HOW TO BUILD IT
Chimney Walls
Walls of chimneys with lined flues, not more than 30 feet high,
should be at least 8 inches thick if made with brick or reinforced concrete, and at least 12 inches thick if made of stone. A flue lining is recommended.
Chimneys can contain more than one flue. Building codes generally require a separate flue for each fireplace, furnace, or boiler. If a
chimney contains three or more lined flues, each group of two flues
must be separated from the other flue or groups of two flues by buck
divisions or wythes at least 33⁄4 inches thick.
Neither the chimney nor the fireplace should touch any wood or
flammable materials in the house structure. Check the local building
code for the proper clearance the chimney must have from any combustibles as it passes through floors, walls, or roofs.
Chimney Height
Proper chimney height on any house depends on the shape of the
house’s roof as well as the positions and sizes of surrounding trees,
buildings, and even hills. The chimney should extend or rise at least 3
feet above flat roofs and at least 2 feet above a roof ridge or raised part
of a roof within 10 feet of the chimney. A chimney hood should be provided if a chimney cannot be built high enough above a ridge to prevent trouble from wind eddies caused by breezes being deflected from
the roof or nearby trees. The open ends of a chimney hood should be
parallel to the ridge (Fig. 16.10).
Chimney Lining
Although a chimney can be lined with brick, there’s less chance of
soot accumulating inside the flue if a clay tile lining at least 5⁄8-inch
thick is used instead. The joints between such tiles must be completely filled with mortar and finished smooth on the inside. The lining is surrounded with a brick, stone, or concrete block wall at least 8
to 12 inches thick. The inside of the fireplace will be finished with
firebrick sides and back.
Chimney Mortar
Brickwork around chimney flues and fireplaces should be laid with
cement mortar. It’s more resistant to the action of heat and flue gases

than is lime mortar. Firebrick should be laid with fire clay. Mortar will
not stand up to intense heat as well as fire clay will.
This is an example of why it pays to have only experienced masons
work on fireplaces. It’s a shame, but they’re a disappearing breed, the
fireplace specialists—going the same way as plasterers and stone
masons. Even some of the masons who claim to know what they’re
doing, do not. They leave behind a trail of fireplaces that smoke, draw
poorly, and have flues that are constantly accumulating thick deposits
of creosote. That’s why, when putting up a masonry fireplace, it’s best
to select someone (or make sure the contractor chooses someone) who
is a proven professional.
Chimney Damper
The fireplace and chimney are large heat gobblers, particularly
when they’re not in use. Because of this, a fireplace chimney should be
398
HOW TO BUILD IT
equipped with a metal damper that can be closed when the fireplace is
not in service, to prevent a continual draft. The damper should be the
kind that opens and closes by increments, so airflow can be regulated
when the fireplace is needed. A fireplace damper is typically about 36
inches wide.
Chimney Cap
The chimney cap, by definition, is placed at the very top of the
chimney (Fig. 16.11). The top surface of the chimney cap should be
given a slight downward slope for water to run off. This watertight cap
prevents moisture from entering the brick, stone, and flue lining. Typically, the cap is made of concrete.
Spark Arrestors
Each year many fires are caused by sparks or flying embers escaping from chimneys. Those same sparks and embers can also damage
roofs. A chimney spark arrestor is a metal device with metal caging on
the sides and a solid metal top. It is fastened over the chimney top
opening to not only stop sparks, embers and pieces of burning material from getting out of the chimney, but also to prevent rain, leaves and
animals from entering. Spark arrestors can also reduce “down drafting,” which is smoke that either starts to
travel up the chimney but then backs
down the chimney, or smoke that has
escaped from the top of the chimney that
“pushes back” into the chimney due to
wind or air-movement patterns created by
nearby structures or trees. Select only
spark arrestors that are UL labeled.
Chimney Flashing
F I G U R E 1 6 .11
Chimney cap.
The intersection of the chimney and
roof should be flashed with metal shingles
which extend at least 4 inches under the
roof shingles and 4 inches up the outer
face of the chimney. They should also
overlap each other by 3 inches to provide
a watertight seal along the chimney. Coun-
FIREPLACES
terflashing should be installed over the top of the metal shingles, again
overlapping by at least 3 inches. Counterflashing should be embedded
at least 1 inch into the masonry (accomplished, of course, as the chimney is being constructed, so the 1-inch counterflashing lip can be
mortared in between a course of bricks or stone) to prevent water from
running behind the flashing and into the house. The flashing seams
where it meets the shingles should be caulked and then coated with a
rustproof paint (Fig. 16.12).
Chimney Sealing
Once the chimney is complete and cured, the contractor should
seal the outside masonry with a transparent penetrating water-repellant sealer developed for stone, brick, concrete, and general masonry.
It should be a sealer that’s specifically made for the application—that
establishes a moisture barrier yet allows the surface to breathe.

399

HOW TO BUILD IT
The exterior walls and cap will naturally encounter rain, snow, ice,
wind, and other conditions as time goes on. Those exterior chimney
components, if not treated, may eventually absorb water. If water gets
into the chimney wall, it could cause cracks and chipping, especially in
cold climates, with their alternating freeze/thaw cycles. Eventually the
moisture could work its way into the house and cause damage to your
insulation and ceiling. The masonry sealer will help keep your chimney
in good condition from the very start, and it will also help prevent
spalling and efflorescence. It should be reapplied as recommended by
the manufacturer, as a planned preventive maintenance measure.
Chimney Cleaning
All wood fires produce some creosote, and flues should be
inspected periodically to check the amount of creosote present inside
them. Creosote can build to thick deposits that become extremely
flammable and can result in dangerous house fires.
When the flue’s insides are coated with uneven surfaces of black
gummy-looking material and you can’t discern the tile and mortar
joints, it’s time for a cleaning. The term “chimney sweep” isn’t really
accurate. Creosote is so hard and gummy that it can’t be swept loose.
Rather, it has to be chipped away from the masonry with a blade. In the
meantime, care must be taken not to knock out mortar joints or damage the flue lining. Because it’s such an infrequent and important task,
and specialized tools are needed, it’s best to hand the job over to a
commercial chimney sweep or cleaning outfit.
HEARTHS
The fireplace hearth is really an extension of the fireplace floor that
protects the surrounding room floor area from catching fire. Typically,
it’s the brick, stone, or concrete pad beneath and in front of the firebox.
Practically any noncombustible material can be used, including brick,
concrete, adobe, terrazzo, quarry tile, marble, mosaic tile, slate, fieldstone, and even bronze or copper if laid over a noncombustible base.
Because the hearth cannot safely rest on the floor or wood framing,
it should either be cantilevered out from the foundation or the foundation should be extended under it. It must be supported from the
ground up, beginning with a concrete pad 12 inches thick or more typ-
FIREPLACES
ically part of the entire fireplace footer, and then brought up to the subfloor level with concrete block.
A hearth should extend at least 20 to 24 inches into the room and
at least 6 to 8 inches on both sides of the fireplace opening. It can be
flush with the floor so that sweepings can be brushed into the fireplace, or it can be raised. Raising the hearth to various heights and
extending its length is a common practice, especially in contemporary
designs. This can create a natural seat for people to rest on and warm
up for brief periods after a cold winter evening of skiing or tobogganing. When done on a smaller scale, though, raised hearths can also present a hazard for tripping over.
COVERS AND SCREENS
Suitable screens should be placed in front of all fireplace openings
to minimize the dangers from sparks and exploding embers, and to
keep young children from playing with and in the flames. Some wire
mesh screens tend to be messy looking, especially when they’re not
permanently attached to the sides of the fireplace opening. It’s better to
go with ones that are suspended across the opening and can be
removed when the fire needs tending. Glass screens or doors are even
better because they’re ideal for safety, are attractive, and they can be
closed at night to reduce heat loss that would otherwise go up the
chimney during cold weather. They can also be used to prevent any
smoke from being blown back down the chimney into a room by a
strong fluke downdraft.
MANTELS
There’s no strict rule dictating that every built-in fireplace must
have a mantel. Many do not; quite a few contemporary designs carry
the wallcovering material—usually brick or stone—right up to the
edges of the fireplace opening. Most traditional fireplaces, however,
still have mantels. Mantels can be made of practically any sturdy
material, from a slab of rough-hewn oak, to granite, marble, slate, and
even concrete. Some consist of elaborately carved wood.
All wood mantels must be set back from the fireplace opening
edges to keep the wood from catching fire. The minimum clearance
401
402
HOW TO BUILD IT
from the front of a fireplace is at least 14 inches away from the
opening.
ASH PITS
A fireplace ash pit or soot pocket is formed in the hollow space
within the foundation walls and is connected with the fireplace by a
small metal door called an ash dump. Some fireplaces have them and
others don’t; it depends on the fireplace design and how often the
owners will be burning wood. With an ash pit, to get rid of ashes and
soot you simply open the ash dump door and scrape or shovel the
ashes into the pit. Then they’re removed through a tight-fitting metal
cleanout door (about 10 by 12 inches) located in the foundation wall of
the basement. In houses without basements, the pit takes the form of a
metal bucket that is lifted out through the hearth when full.
In recent years, the ash pit is often placed on the outside of the
chimney. This arrangement is workable in houses with or without
basements, providing access to the ash pit from the outside, where the
ashes are ultimately disposed of anyway.
DIRECT-VENT GAS FIREPLACES
Are you reluctant to fuss with all of the activities associated with
wood-burning fireplaces, such as the procurement, cutting, storage
and handling of firewood, disposing of ashes, as well as performing
chimney and flue cleaning and maintenance? Then consider directvent gas fireplaces.
They come in a variety of attractive designs. Contemporary models
include corner, three-sided peninsulas, see-through, arched, bay-front
and other styles. The burning process is totally sealed from indoor air.
Combustion air is drawn from outdoors and the flue gases go back outside through one special dual-channel pipe. No air is lost during the
process, and there are no drafts or dust involved. They burn clean, efficient gas and need only an access through an outside wall right behind
or above the fireplace for the exhaust hardware (Fig. 16.13). No expensive chimney is required.
Direct-vent gas fireplaces are efficient, too, up to 80 percent. Using
one of these units can cut utility bills because it allows the home ther-

mostat to be set lower. For convenience, you can select a model with a
hand-held remote control, which allows you to simply push a button
to start a fire in the hearth. Other remote buttons control flame size,
heat output, room temperature, and optional blower speeds.
Many of the better models have optional battery-powered ignition
systems, or generate their own electricity from a pilot light. They will
operate during an electrical power outage even when your furnace
won’t.
FIREPLACE ENERGY EFFICIENCY
The two major keys toward maximizing the energy efficiency of a
fireplace are by reducing the amount of already heated up room air
that escapes up a chimney, and, by directing or sending more heat
403
404
HOW TO BUILD IT
from the fire out into living spaces. Then, by running a furnace blower
or other blower on continuous air circulation, the heated air in the fireplace room can be distributed throughout the home. There are numerous steps you can take to accomplish the above, including:
1. The fireplace can be completed with tight-fitting glass fireplace
doors with adjustable air openings. These glass doors not only
block large amounts of indoors heated air from being drawn up the
chimney while the fire is burning, but also when there is no fire.
Some doors use magnets to keep the doors closed; others use cam
mechanisms. High-temperature silicon gaskets provide excellent
seals. These doors are available in attractive finishes such as polished nickel, copper, and pewter.
2. A heat-circulating grate and blower installed in the fireplace will
greatly assist heat distribution. The quiet built-in blower draws
cool room air into the grate so that air can be heated as it circulates
through grate tubes before being blown back out into the room. The
grate is typically constructed of steel pipes, that, again, enable
cooled air to enter and heated air to be blown out. Since the grate
base is only a few inches high, it fits under the glass doors (Fig.
16.14). The heat output can be as high as 40,000 Btu per hour.
3. Models with a built-in thermostat and a variable-speed blower provide the most control over heat output
and noise levels. The thermostat turns
the blower on automatically when it
senses about 110 degrees Fahrenheit,
and off again at about 90 degrees
Fahrenheit.

4. Consider the installation of a fireback,
made of heavy cast-iron plate. Such a
fireback positioned at the back of the
fireplace will get very hot. It helps
absorb—and then radiate—additional
fireplace heat into the room, heat that’s
otherwise lost up the chimney. Many
commercial firebacks have decorative
patterns cast into their face (Fig. 16.15).

➤➤➤➤➤ POINTS TO PONDER
1. Before you rule out a fireplace,

to sell.
2. Many people install fireplaces but are reluctant to use them
because they have installed a light-color plush carpeting in the
room, or they have no place to stack the wood, or they simply
don’t want the ashes and debris from burning and handling
wood in the house. If you definitely plan to use your fireplace(s), plan the room’s furnishings and wood supply storage
accordingly, so a bit of ash or dirt here and there won’t create a
federal case.
3. Why not select fireplaces that deliver as much heat as possible
into the house? Even though they may be more expensive up
front, they’ll have a continuing positive effect on energy consumption during cool to cold weather conditions.
4. For hundreds of years, Europeans, Russians, and numerous
other groups have been using modular masonry fireplace units
in which hot fires are stoked with wood or coal, and the surrounding firebrick and attractive glazed tile absorb the heat,
store it, then gently release/radiate it throughout the day or
evening, warming the unit’s surroundings. Similar units are
presently available through a number of manufacturers and
distributors.
5. Prefabricated built-in fireplaces not only reduce construction
costs, but make it possible to install a traditional design almost
anywhere in an existing house.
6. Freestanding fireplaces are the least-expensive fireplaces and
the easiest to install. They’re typically made of steel or cast

iron, but are also available in soapstone—a handsome, durable
fireplace and stove material.
If natural gas is available in your area, it’s a good idea to
include a gas starter in a fireplace.
By locating a fireplace on any inside wall, especially the wall
separating the garage from the living areas, the part of the fireplace and chimney facing the garage does not need a facing of
finished brick or stone, plus absorbed heat can radiate into the
garage instead of being lost directly outdoors. This will save
energy and material and installation costs.
Don’t operate an open fireplace without the minimum protection afforded by spark screens. Glass screens and doors, however, are much safer.
For safety’s sake (and to ensure operating efficiencies), fireplaces, flues, and chimneys need to be put on a routine cleaning, inspection, and maintenance schedule.

Plumbing
T
he plumbing and electrical systems in any dwelling can be
considered the actual lifelines of the house. Without them
practically all modern conveniences would be impossible. Due to their
importance, both systems are strictly regulated by local and national
codes, and both are included in ambitious inspection programs
required to ensure the occupant’s safety. This chapter focuses on
plumbing.
The entire plumbing system of a house can be broken into five basic
categories: water supply, pipe types, fixtures, water heaters, and
drainage.
WATER SUPPLY
Your water source can be either public, private, or a combination of
both. Public water systems are the most worry-free, from a homeowner’s point of view. Large water pipes called mains deliver the
water directly to your house in practically all urban locations, ensuring adequate water pressure and supply. Large private water systems
often do the same thing for subdivisions beyond the reaches of public
water mains. These latter full-blown water systems, both public and
private, have strict rules and codes to follow that guarantee proper
hookups to residential and other dwellings (Fig. 17.1).

absolutely must go through joists,
the holes should be cleanly drilled
through the center of a joist, just large enough for the pipe (or
wire) with some clearance to prevent a hot pipe from contacting a wood joist (Fig. 17.2). Check local building codes; they
will provide guidelines. All told, it’s best to discourage hole
drilling.

F I G U R E 17. 2
Water Filters
If you plan to filter your water, you
might as well have a filter unit installed on
the main water supply pipe as soon as it
enters the house (Fig. 17.3).
■ A filter can remove sediment, lead,
rust, sand, silt, sulphur, dirt, excess
chlorine, and many other undesirable
elements—depending
on
what’s in your water supply.
■
By removing impurities, a filter can
reduce odors and improve the
water’s taste.

Installing filters from the start protects pipelines and water equipment, (water heaters, cooling

equipment, washers, dishwashers, and ice makers) from any
harmful scale elements.
■
Installing filters can possibly protect household members from
potentially harmful elements.
Water Wells
Beyond the big water supply systems, things get personal. Since
the first settling of America, private wells or springs have provided
rural farms and homesteads with their water. Wells are not as regulated as large water systems, and if you need one it’s best to consult
local professionals familiar with the conditions and special situations
that exist in your area. There are certain constants, however, you
should be aware of when putting in a well as your main source of
water supply:
1. Locate the well as close to the house as possible, yet as far away
from any septic disposal system as practical—preferably uphill
from it. You certainly don’t want to contaminate your water with
sewage leachate. Also consider the possibility of sewage systems
that future neighbors might install to the sides or back of your property, and keep in mind that presently uncontaminated rivers,
streams, lakes, ponds, and swamps might not always remain so. Try
to position the well at least 50 feet away from any of them.
2. When the well is completed, have it tested for water flow, purity,
taste, and even color. If any irritating characteristics persist, such as
“hard” water (having higher than usual concentrations of dissolved
solids), a metallic taste, or a cloudy or off-color appearance, determine if those qualities can be effectively handled with a water softener/treatment unit that attaches to the well.
3. Protect the pipe that transports water from the well to the house
from freezing temperatures. This can be achieved by burying the
pipe below the frost line, lagging or wrapping it with insulation, or
attaching electrically heated wire to the pipe (heat tape). It won’t
matter how good the rest of your plumbing is if the supply line
freezes in midwinter. Frozen pipes are expensive to thaw and can
cause a lot of damage if they burst.
PLUMBING
PIPE TYPES
Cast-Iron Pipe
Cast-iron pipe might be heavy and awkward to handle, but it’s so
strong and durable it’s been in general use for drain, sewer, and vent
lines for years. Compared with plastic pipe, cast iron has two major
advantages. First, it delivers its contents with much less noise. If you
can’t avoid running a waste pipe through a wall adjacent to a living or
dining room, cast-iron pipe will prevent many uncomfortable
moments you would otherwise be spending listening to water and
waste gurgle through the line. Second, cast-iron pipe is more durable,
and able to withstand the rigors of the “Roto-Rooter” and other
mechanical and chemical pipe-cleaning equipment.
Galvanized Steel Pipe
Galvanized steel pipe is what was most commonly used for transporting water before copper lines gained widespread acceptance. It’s
available in various lengths and diameters, and has a rust-resistant
coating on its inside and outer surfaces. Connections are usually made
by cutting threads into the pipe, and because this is done after the protective coating is applied, any exposed threads will rust.
Because of its strength and wall thickness, steel pipe has a long life
expectancy even when buried and is frequently used to supply natural
gas as well as water. It’s still a popular choice whenever a “rough”
plumbing line is called for. The principal drawback is the pipe’s
roughness, which contributes to water-flow friction and the collection
of mineral deposits and sediments that over the years tend to reduce
the inside diameter of the pipe in the same way that cholesterol can
accumulate and restrict a person’s arteries.
Copper Pipe
Copper makes an excellent pipe. It comes in soft, flexible, and hard
varieties, has a very long life, and—if not spliced into galvanized steel
pipe—is generally not affected by corrosion. It’s the number one
choice to supply hot and cold water throughout today’s modern
houses. Copper lines are somewhat more expensive when compared
with other piping, and so is the labor needed to install them. Individual pieces are connected by soldering them to copper unions, Ts,
411
412
HOW TO BUILD IT
elbows, and other fittings. A major advantage of copper pipe is that it
can be bent or curved rather easily, a characteristic not available with
cast iron, galvanized steel, or most plastics. However, due to their
nature, copper pipes require special pressure chambers to prevent
“water hammer”—a shuddering, rapping noise created by a sudden
turning off (or on) of the water. Like most other pipes, copper can be
ruptured by water freezing inside.
Plastic Pipe
Plastic pipe is substantially less expensive than copper, galvanized
steel, or cast iron. Plastic pipe is also simple to install and keeps labor
costs low. There’s no need to solder with torches, and no measuring
and threading the ends of galvanized steel stock. There’s only convenient plastic fittings, easy-to-cut plastic pipe, a can of plastic cement,
and a brush. Almost anyone can do it.
There are other advantages to plastic pipe. It’s extremely lightweight and easy to support. Plastic is chemically inert and unaffected
by corrosive materials. The smooth inside surface of plastic pipe aids
the movement of materials through the lines.
A few major disadvantages, though, eliminate the use of plastic
lines from several parts of a house. It’s not as strong as cast iron,
galvanized steel, or even copper, plus it doesn’t have the bending
capability of copper. Because of its tendency to crack under heavy
loads or stress, it shouldn’t be used beneath or within a concrete
slab where long, strong lengths of pipe having no splices are
needed. As mentioned before, to the unwary, the noise that water
makes when running through plastic lines can be a serious source
of irritation if used above or near first-floor living areas, especially
in multilevel houses. Plastic pipe will also burst when water
freezes inside it.
A good-natured battle wages between the proponents of cast iron,
galvanized steel, copper, and plastic for dominance over the entire
house plumbing material question. The most sensible approach, and
one favored by many residential plumbing experts, is to employ each
kind of material where its strong characteristics can be used to best
advantage. This means cast iron and steel for drainage pipes and for
piping that’s embedded in ground or concrete, copper for water supply, and plastic for venting.

OCUS
PIPE INSULATION
While traditional construction methods prescribe that pipes—especially water pipes—exposed to cold temperatures should be insulated to
conserve warmth or prevent freezing, we take pipe insulation recommendations to another level. Indeed, consider having every pipe—”hot”
or “cold”—insulated with heavy-duty fiberglass or polyethylene foam
tubes, their seams sealed with insulated tape. This should be done in
the home’s initial construction stages. Early on, it’s simple and inexpensive to do. Later, once walls, ceilings, and floors are enclosed or covered, simple access will be lost.
A couple of points to consider regarding insulating pipes follow:
■
Piping in attics, garages, crawlspaces, and outside walls is especially vulnerable to freezing if nearby cracks and other openings
let in cold air. If any areas of piping will be exposed to extremely
cold temperatures, consider using a combination of insulation
sleeves or tubes with electrical heat tape or a thermostatically
controlled heat cable. Insist that the contractor use only products
approved by an independent testing laboratory such as Underwriters Laboratories Inc., and make sure products intended for outdoors use are labeled that way. Manufacturer instructions must be
precisely followed.
■ Insulated pipes, hot or cold, will maintain more consistent water
temperatures. They will prevent hot water from losing heat and
cooling off within the line, and, conversely, will prevent cold water
from absorbing heat and warming up while it sits in the line. With
insulated piping, water won’t have to “run” as long to reach the
desired hot or cold temperatures at the faucet. In other words,
more hot water will stay hot longer within an insulated line, so it
comes out of the faucet at the desired temperature sooner than
would hot water standing in an uninsulated line that loses its heat
in a cool basement and has to run out (being wasted) at the faucet
until hot water fresh from the water heater can be drawn into its
place. Thus, insulated pipes deliver water at desired temperatures
with less waiting, less wasting of water, and less energy needed for
heating. That’s a savings of water, time, and money.

HOW TO BUILD IT
PLUMBING FIXTURES
Plumbing fixtures include the water heater, sinks, tubs, showers,
toilets, and even outside faucets. The time and effort you spend planning their locations will be the most important part of their installation.
A major consideration is where to position the water heater, and
how to keep as much of the plumbing as possible concentrated in one
area of the house. Hot water will cool off if it must stand in sizeable
lengths of pipe or travel long distances between supply and outlets.
For ease of installation and savings on materials, bathroom fixtures
should line up along one wall, and, depending on the floor plan, the
other side of such a “wet wall” full of plumbing could perhaps accommodate the plumbing support systems of a kitchen, a laundry, or
another bathroom. Compact fixture placement will keep the plumbing
clean and simple.
Another benefit of compact plumbing is that certain fixtures can
share vents. Whenever possible, locate the toilet between the tub and
sink, so the vent from the toilet can perform extra duty. Rookie bathroom planners sometimes ask builders to put the toilet on one wall,
and the bathtub on the opposite wall. That causes unnecessary piping
to be installed at an extra cost.
To save yourself from headaches later on, make certain every fixture can be turned off, preferably via a local or easy-to-get-at water
shutoff valve, in case it’s necessary to isolate the fixture so it can be
serviced or repaired.
Don’t ignore the economy that can be realized through careful planning of the house’s entire plumbing system.
F OCUS
SHUTOFF VALVES
A shutoff, or “isolation” valve, stops water or other liquids or gases
at some point within a pipeline or tank system, typically so maintenance, repair, or installation work can be performed downstream from
the valve. Localized shutoff valves should be installed for all individual
fixtures, such as faucets, bathtubs and showers, hot water heaters, boilers, dishwashers, and others. Don’t allow the plumbing and fixtures to
be installed without these shutoffs, or future maintenance will be diffi-
PLUMBING
cult to accomplish without shutting off and draining main portions of
the home’s plumbing. Shutoff valves should include the following:

■ Shutoff valves should be present at the washing machine, dish■

washer, and refrigerator ice maker.
Toilets will have one cold-water valve usually installed under the
water tank.
Hot-water heating systems have a cold-water shutoff valve near
their boilers.
Bathtub and shower valves should be located behind the faucet
controls.
In addition to providing shutoff valves the contractor should cut
an “access door” or a simple rectangular hole in the back of the
plumbing wall that can be kept covered with a thin, discrete
removable cover—they’re often located out of sight within an
abutting hallway or bedroom clothes closet. The door will allow
access for any needed maintenance once the plumbing is isolated.
The plumbing system should have an indoor shutoff valve to each
sill cock (outdoor) faucet, which enables those faucets to be shut
off and drained from the pipe to the faucet—reducing the risk of
water freezing in the outside part of the faucet and piping during
winter (Fig. 17.11).
Each plumbing system must also have a main shutoff valve, typically located where the waterline enters the house and just before
the water meter, on municipal water systems (Fig. 17.1). The idea
is to be able to quickly shut off the entire water supply in response
to serious leaks or emergencies. Again, if the water must be shut
off at the main valve, remember to follow the boiler or water-heating tank instructions for proper shutdowns. Remember that any fire
protection sprinkler systems will lose their water pressure as well.
Test all shutoff valves, from the main valve to the individual fixture shutoffs, with the entire plumbing system activated, to see if
they individually work or hold.
Insist that the contractor tag basement shutoff valves with labels
that tell what each valve shuts off, to prevent errors from being
made if you ever have to activate them during an emergency.

HOW TO BUILD IT
DRAINAGE
Sufficient capacity and pitch, tight sealing, proper venting, and
provisions for cleanouts are all important to a good, effective drainage
system. Used water and the waste it carries must be disposed of, both
for convenience and for the sake of your health. Waste creates unpleasant and potentially harmful gases that must be expelled. A drainage
system therefore has two functions: to transport water and solid
wastes to a sanitary sewer or septic tank, and to dispel noxious gases
into air you won’t be breathing.
If everything has been well planned, the waste water and materials
will flow by gravity alone. Consequently, all drainage parts must be
pitched or sloped downhill. These parts must be connected with special fittings and be large enough in diameter and smooth enough
inside to prevent accumulation of solids at any point. This also means
the fewer drainage parts, the better. It might not sound very exciting,
but it’s true: the entire plumbing installation is generally planned
around the drainage system—to drain as many fixtures as possible
with the same main pipe, and, the fewer main pipes, the better. This
setup makes venting easier, too.
There are four topics important enough to discuss by themselves
when it comes to drainage: the plumbing lines that drain the house’s
internal plumbing fixtures, the private, individual sewage system or
septic tank, cleanout plugs, and venting.
The Fixture Drainage Lines
All drainage lines must be pitched toward the sewer pipe. Tests
have proven that a 1⁄4-inch pitch per foot of run will allow practically
all waste to move freely, even though it doesn’t seem like much of a
slope. At the other extreme, a pitch of 45 degrees or more (1 foot of
pitch per foot of run) provides a much stronger flow. If a straight run
can’t be accomplished with a sizeable pitch of 1⁄2 inch per foot maximum, the largest part of the run should be made using the latter pitch
and the remainder sloped at 45 degrees.
Drainage line piping should use 45-degree elbows to minimize flow
resistance, instead of 90-degree elbows. Using 90-degree elbows will
slow down the drainage flow and increase the chance of a drainage
plug up.
PLUMBING
The slope and size of the trenches required to be excavated for the
disposal lines are also important, and depend on the type of soil and the
contour of the land. Ideally, excavators will dig all the drainage trenches
at the same time they are completing the foundation preparations.
Septic Systems
Because drainage systems that malfunction can affect the health of
the entire community, there are usually stringent regulations governing private or individual sewage systems.
The best all-around individual sewage system is the septic tank
(Fig. 17.4). The septic tank system consists of a house drain, a septic
tank, an outlet sewer, a distribution box, and a disposal or leachate
field.
The location of a septic tank and leachate field on a building site
will be partly determined by the lay of the land, since the drainage
must be downhill and away from the water supply. Also remember
that you need access to the tank when it must be serviced or repaired.

HOW TO BUILD IT
The soil pipe is the main drain from the
house to the septic tank. It’s usually made
from a sturdy 5-inch cast-iron pipe that’s
pitched at an ideal slope.
The septic tank will most frequently be
tar-coated steel or concrete (Fig. 17.5).
Concrete costs more but lasts longer. When
raw sewage enters the septic tank, bacterial action breaks down the solids into liquids and gases that drain off through an
outlet sewer into a box that distributes

them into the disposal field. This field is

an area beneath the surface of the ground that
“absorbs” and “cleans” the waste through natural processes of decay.
The size of a septic tank is important because a tank that’s too small
will accumulate sludge that can back up into the house.
If you will need a septic system, be careful when you select your
building site. Building sites seem to be getting smaller all the time.
Once wide-open land is being built up. The space required for safe
waste disposal is dwindling, and in some close-quartered neighborhoods, nonexistent.

SEPTIC SYSTEMS
A septic system is one of those hidden support systems that nobody
thinks about until something goes wrong with it. To city dwellers who
are used to the effortless convenience of sanitary sewers, septic systems are mysterious subterranean pipes and tanks that surely must take
care of themselves.
Well, nothing could be further from the truth. Ask anyone who was
raised on a farm. A septic tank system biologically breaks down household sanitary wastes. Bacteria within the system helps decompose the
solid wastes. As these tiny microorganisms grow, feed, and breed in the
septic tank and lines, most of the wastes are rendered into liquids that
are trickled or leached into the ground through a “leaching field” of
perforated pipe laid in underground beds of gravel. Some of the wasteladen sewage water that leaches through the disposal lines is addition-
PLUMBING
ally decomposed or purified by natural bacteria found in the ground
from 2 to 6 feet deep. Other wastes, however, remain inside the septic
tank in the form of a sludge that gradually accumulates. A wide variety
of factors can influence a septic system’s operation.
The contractor who installs your septic tank should supply you with
information so you can inspect and arrange for maintenance services on
the entire system. The following points are likely to be similar to the
advice you should get.
SEPTIC SYSTEM INSPECTIONS: WHAT TO LOOK FOR

by inserting a long stick into the tank. When the total depth of
solids exceeds one-third of the tank’s capacity (certainly no more
than one-half), it’s time to have the tank pumped out and the
solids removed. On many septic systems, if the sludge is allowed
to accumulate it will eventually fill the tank so there is no room
for waste to enter from the house. If this happens, the tank may
overflow and saturate the surrounding grounds with horriblesmelling raw sewage.
Sluggish or plugged waste in sewer lines.
When septic tanks are not functioning properly, a side effect is
that lines running from the home’s toilets are slow to convey
wastes from the toilets to the septic tank. Solids and waste paper
begin to settle and accumulate in the lines. Eventually, the whole
system could back up.
Unusual foliage displays above leaching fields.
Look at the grounds above and adjacent to the leaching field.
Abnormal or luxuriant lawn conditions are an indication that the
soil is being overloaded with waste-laden nutrients. Wet, soggy
soil is another characteristic of failing absorption fields or
clogged septic tanks. A good time to inspect leaching fields is
during very wet weather. The size and composition of the leaching
field should be sufficient to absorb household wastes and rainwater at the same time. If a heavy rain overloads the system, and
turns the leaching field into a swampy mess, improvements
should be considered—perhaps adding more lengths of drainage
pipe. Most problems are caused by the quality of soil around the
419
420
HOW TO BUILD IT
leaching field. If there’s a lot of clay present in the soil, good
drainage will be almost impossible to achieve.
■ Trees and large shrubs growing on leaching fields.
■ Roots can reach into the absorption beds and clog perforated piping. Make sure trees and large shrubs are not encroaching over or
immediately adjacent to septic system leaching fields.
SEPTIC SYSTEM REPAIRS AND MAINTENANCE
As far as repairs go, few individuals look forward to working on septic
systems. Special tools and equipment such as heavy-duty pumps and
vacuum units are often required.
1. Septic tanks should be cleaned periodically, or when they need it.
Most should be checked twice, or at least once a year to see that
they’re in working order. Typical septic tanks need cleaning about
every two or three years. Ideally, the cleaning can be done in the
spring. Because the waste material can give off obnoxious odors and
may contain disease bacteria, and warm weather accelerates bacteria action, it’s best to pump and get rid of the waste before hot
weather sets in. Cleaning a septic tank is not recommended as a doit-yourself project. There are qualified companies that specialize in
working on septic, well, and similar plumbing systems. They’ll have
the knowledge and equipment, and they’ll also know where to get
rid of the waste. It can’t and shouldn’t just be dumped anywhere.
2. Leaching fields should be kept free of trees and shrubs.
3. Avoid connecting nonessential home wastewater streams to a septic system. Runoff from gutters should be channeled elsewhere, as
should discharge water from swimming pools and sump pumps.
4. Review with other family members what household wastes should
not be put into septic systems.
■ If you have a kitchen garbage disposal, try not to grind and
dispose of large amounts of vegetable and fruit matter. It’s
much better to dispose of them in an above-ground composting bin or pen, along with grass clippings, leaves, and similar
vegetable and plant matter. Kitchen sink waste that’s introduced to a septic system takes more time to be broken down
by bacteria than do human wastes. If kitchen sink wastes are
sent to the septic system, it will probably mean more frequent
septic tank pumping and cleaning.
PLUMBING
■ Avoid using drain cleaners and high-foaming detergents if the
plumbing they go into is connected to the septic lines. Those
substances will kill bacteria that’s needed by the septic system
to break down regular wastes. Low- and nonfoaming detergents
are okay to wash with. So are nonphosphate and biodegradable
laundry soaps.
■ Never let petroleum products, paint thinners, solvents, cleaning fluids, dyes, cigarettes, plastics, or similar materials enter
a septic system. Most are harmful (or neutral) to the bacteria
that grows, feeds, and breeds in the septic tank.
■ Grease from cooking juices and related activities should be
reduced as much as possible. Grease, animal fats, and related
food particles tend to float and accumulate in the top layer of
lighter-than-water scum and slime that’s present in all septic
tanks. It’s usually pumped out during regular maintenance of
the tank. Naturally, never pour grease down a kitchen sink.
Instruct family members to scrape and wipe as much grease as
possible from cooking pans before immersing the pans in
soapy water.
■ Also avoid placing modern “flushable” sanitary napkins into a
septic system. Naturally, that goes double for regular types of
sanitary napkins as well.
NEW SEPTIC INSTALLATIONS
When planning a new septic system, the most critical factor is the
type of soil the ground is made of. Soil having good drainage will make
things easier. As a general rule, a three-bedroom house should have, at
minimum, a 900-gallon septic tank. A four-bedroom dwelling should
have a tank with at least 1150-gallon capacity. Since the septic tank
and system is so critical to the daily operation of a household, leave
nothing to chance. Get some professional help. Check with companies
that have installed systems near your location. They’ll know what to
look for and what to look out for as well. Also consider the following
options, all designed to take the pressure off of the septic system:
■ In many areas, building codes insist that all toilets must be con-
nected to a sanitary sewer or septic tank. These codes have not
caught up with all of the advances made by toilet manufacturers.
There are toilets available that perform their own decomposing
operations, channeling the waste (along with a very small amount
421
422
HOW TO BUILD IT
of water) to relatively small tanks that are usually installed in a
basement. These tanks need to be emptied as few times as once
per year. And by then the waste has been broken down into a
practically odorless material. Composting toilets thus greatly
reduce the amounts of solid wastes going to a septic tank, and
the overall amount of water used in a bathroom.
■ A less-radical option is one of a number of new toilets designed
to use less water per flush. Since even now, at this very moment,
new designs are on the drawing board, check with local plumbing
supply houses for news on the most water-efficient models.
■ Another workable idea is to use two separate septic tanks: one for
solid waste and the other for what’s known as gray water. Gray
water is wastewater that’s not heavily laden with solids. It
includes rinse and other water from clothes washing machines,
dishwashers, showers, bathtubs, and even sump pumps. The gray
water can be routed through its own tank to the leaching field, so
it won’t overload the main septic tank.
NOTE
■ Large vehicles should not be allowed to drive over septic tanks or
leaching fields. Be especially wary of large, heavy rigs such as
concrete trucks, front-end loaders, bulldozers, drilling outfits, and
the like.
SEPTIC TANK QUICK CHECKLIST
1. Septic tanks should be cleaned out when the total depth of solids
within it exceeds between one-third and one-half of the tank’s
capacity.
2. Have septic tanks inspected at least once a year, typically during
spring.
3. Keep trees and large shrubs from growing over the system’s leaching field.
4. Avoid routing gray or nonsanitary wastewater to the septic system.
5. Keep kitchen wastes out of the septic tank. Same with petroleum
products, paints, solvents, and similar materials.
6. Don’t use drain cleaners or high-foaming detergents if the plumbing they drain into is connected to a septic tank.
PLUMBING
Cleanout Plugs
The importance of cleanouts in a plumbing system becomes apparent as soon as there’s a blockage somewhere. Plumbing stoppages
occur due to a number of reasons, including the following:
■ Foreign objects lodged in a drainage line
■ An accumulation of hair or other matter
■ Deposits of grease, fat, or other congealed substances
These materials can completely block the discharge through
drainage lines, or at least greatly reduce effective flows. Complete blockages cause considerable damage to the lower floors when wastewater
backs up. Even partial stoppages can create conditions in drainage lines
that interfere with proper venting. In turn, poor venting results in the
escape of foul gases and odors into the living areas of the home.
Pipe drainage cleanouts should be accessible for servicing. The
contractor should provide an out-of-sight access door for any that are
located within a wall.
Venting
A plumbing or building trap is a device installed in plumbing that
prevents the intake of sewer gas into the interior piping system. A
cleanout at the trap offers access to the house’s sewer line between the
dwelling and the outside street sewer facilities. Other gases and odors
in a home’s plumbing are kept in check and vented from the house
through piping that runs up through the roof. At the same time, this
prevents gurgling or sucking sounds after a fixture is drained and protects trap seals from siphonage and back pressure.
It’s best to specify that the vent pipe or pipes be installed near the
rear of the house so that they’re not readily visible from the street
(Figs. 17.6 and 17.7).
WATER HEATERS
Until fairly recently, most homeowners had only one basic waterheater type available for their home hot-water use: a tank water heater.
Today, tank water heaters still make the majority of water heaters sold
and installed for home use. But another type of system is likely to con-

tinue to gain wider acceptance in the near future: that of the tankless
water heater. Most water heaters are fired by either natural gas,
propane, oil, or electricity.
Tank Water Heaters
The capacity of a tank water heater is an important consideration.
The water heater should provide enough hot water at the busiest time
of the day or night. The ability of a water heater to meet peak demands
for hot water is indicated by its “first hour rating,” which accounts for
the effects of tank size and the speed by which cold water is heated. A
standard tank of 40 or 50 gallons is usually sufficient for a family of
four living in a house having two and one-half bathrooms, but larger
tanks are available for high-volume water users.
A number of points regarding water tanks should be kept in mind:
1. Look for a unit that has a self-cleaning system that creates a turbulent swirling action as water enters the tank, thus fighting sediment
build-up, improving operating efficiency and lengthening tank life.
2. Some tank heaters are available with set-back adjustable thermostats. Units with multiple temperature settings are convenient
425

SAFETY >>>NOTE
HOT-WATER-HEATING SYSTEM SHUTOFFS
When shutting the water off to the boiler or other parts of a hotwater-heating system or to a hot water heater (tank), carefully follow
the manufacturer’s instructions. If a boiler or hot water heater runs out
of or low on water, serious damages (including explosion and fire) and
injuries can result.
F
OCUS
WATER SOFTENERS
Also referred to as water conditioners, when the quality of available
water is less than ideal, the installation of water softeners or conditioners can provide a number of major benefits, including the following:
■
Filtering potentially harmful contaminants out of the water
■ Removing miscellaneous unpleasant tastes and odors from the
household’s drinking water
■ Softening hard water reduces build-up of hard-water soap curd,
which can gum up the insides of appliances. Less soap-curd
deposits can mean dishwashers, clothes washers, and water heaters
will operate more efficiently, for a longer lifetime.
Hard water typically contains unusually high amounts of minerals and
metals, including iron, calcium, and magnesium. This water can wreak
havoc within a home, causing soap scum and lime deposits to form on
numerous appliances, fixtures, and plumbing components. Hard water
will leave streaking windows, bathtub and toilet rings, tainted appliances, plugged showerheads, restricted flows in pipes, and other nagging problems. Water softening is by far the most common treatment
required to hard water supplied by wells and some private or municipal
water authorities. Advantages of softening hard water are many. They
include the following:
■ Hard water causes lime scale buildup. Lime scale coats moving
parts in appliances, causing them to operate less efficiently. Lime
scale collects within water heaters, reducing heat exchange efficiencies and increasing the cost of heating water. Lime scale clogs
pipes and fixture internals and slows the delivery of water throughout the home.
PLUMBING
■ Hard water will discolor bathroom and kitchen fixtures.
■ Soft water works far more efficiently with soaps and detergent clean-
ers. For clothes, shorter wash cycles and cooler water will suffice when
soft water is employed. In some cases, for the same results, twice as
much cleanser is needed when used with hard water. Hard water can
also reduce the life span of clothes when lime “curd” deposits cause
difficult-to-remove yellowish or gray stains. For people and pets, bar
soap and shampoo usage will be reduced with soft water. Hard water
can dry skin and hair because the minerals within the water combine
with the soap to form a sticky residue that’s hard to rinse away.
People who use hard water tend to use more skin-softening lotions
and hair conditioners.
SELECTING WATER SOFTENERS/CONDITIONERS
Consider the following points when reviewing your water softener or
conditioner needs:
■ First, test your water so that you know exactly what problems, if
any, you need to solve. A local water treatment company expert can
perform a preliminary analysis, usually at no charge.
■ Conventional softening equipment works via an ion exchange. The
softening tank is full of tiny porous plastic spheres that attract
hard calcium and magnesium ions. When the spheres are full of
these hard ions, a regeneration cycle starts to clean off the spheres
so that they can be used again to soften more water. For maximum
savings, look for a sphere-cleaning system that uses a salt solution
and water. Further, a demand-initiated regeneration system actually meters water usage and only regenerates on demand—unlike
units that use timers to regenerate at preset intervals, which can
require twice as much salt and water. Give serious consideration to
a twintank system that allows switching from one softening tank to
the other as they exhaust their softening capability, to provide an
uninterrupted flow of soft water 24 hours per day.
■ Lean toward reliable systems not subject to electric timer malfunctions or power outages. Cost should not be the main issue when it
comes to water softening and conditioning. You’ll want equipment
that operates without interruption, is easy to care for, and produces consistent desired results.
427
428
HOW TO BUILD IT
and can save energy costs when water can be kept cooler during
certain times. Some models are manufactured with a timer and
integral thermostat that automatically raises or lowers the water
temperature in the tank up to four times per day, to conserve
energy. If need be, each day can be programmed differently. This
control system enables the unit to reduce the temperature temporarily when hot water is not in demand, such as when you’re
asleep or at work. A manual override can be accessed when a preset schedule must be changed.
3. Install them near the highest hot-water demand areas in order to
reduce wasted energy from running the water long distances. If
your house will have two equal demand areas, try to center the
water heater between them. If your furnace and hot water tank vent
through the chimney, they will logically need to be near each other.
However, many of the high-efficiency furnaces and hot water tanks
have their own direct vent system, allowing them to be vented
straight to the outdoors. Because a hot water heater or tank will
wear out in time, you should be able to easily access it for removal,
and the inspection panels and drain valve must also be simple to
get at for maintenance and repairs.
4. Check to see if adding insulation to your water heater will affect the
warranty. If additional insulation is desired, follow the instructions
from the water-heater manufacturer.
5. A water heater tank must have a drain near the bottom so you can
easily drain the tank when needed, and can periodically flush out
sediments that collect at the tank’s bottom. Unless you have soft
water, it’s important to drain water from the bottom of a waterheater tank periodically to help remove hard-water deposits that
may accumulate on the tank’s bottom. These deposits effectively
act like insulation. They eventually surround the heating element
and force it to work harder and harder at heating the tank’s water.
Removing these sediments by periodic draining of small amounts
of water from the tank’s bottom will help keep the system healthier
and less expensive to operate.
6. When locating a gas water heater in a garage, keep it raised off the
floor so when the pilot ignites the gas burners it doesn’t cause any
floor-hugging gasoline fumes from a lawnmower or auto to explode.
PLUMBING
Tankless Water Heaters
Also called “demand” water heaters, these tankless units provide
alternatives to the standard hot water tank. Why consider tankless
units? There’s less risk of a water rupture—with all of the water damage such an unexpected event can cause. Also, tankless water-heating
equipment will likely last longer than components of a tank heating
system. Tankless components are less subject to corrosion. The highest
quality models use stainless steel, copper, and brass for parts that contact water. If a component malfunctions, it can be repaired. There’s no
tank to rust out, so the entire unit never has to be replaced.
Too, tankless systems provide hot water where and when you need
it, without relying on a preheated inventory of heated water. Considerable energy is lost from heated water that simply stands in the tank
all day and all night. Tankless units also virtually eliminate standby
water heat losses—energy wasted when hot water cools down in long
pipes or while sitting in a storage tank. By providing heated water
immediately where it’s used, tankless water heaters waste less water.
People don’t need to let water run as they wait for warm or hot water
to reach a remote faucet. A tankless water heater, correctly sized, provides almost unlimited instant heated water as long as the system is
used within its capabilities.
For example, when someone opens a hot-water faucet within a
home’s plumbing system, the tankless water heater “senses” this—
starting the gas burner or the electric elements that heats the water as
it flows toward the faucet. By using standard fuels such as electricity,
gas, or propane as a heat source in this remarkably efficient system,
tankless water heaters can reduce a household’s water-heating bill by
10 to 20 percent, or more. The top models have modulating gas-valve
or electric-heat output, and solid-state controls maintain a steady hotwater temperature. These designs ensure a constant water temperature
from a faucet’s trickle to a shower’s full-force spray.
As a rule, tankless water heaters are a lot smaller than water-heater
tanks; some are only 36 inches high and hang on a wall (Fig. 17.8), others are about the size of a bread box. When compared with bulky water
tanks, those units use far less of valuable square footage living space.
Direct-vent models are available, as are units with electronic ignition
to save energy otherwise consumed by a continuously burning pilot
light.

A tankless water heater.
Are there any downsides to installing tankless water heaters? One
could be that in the event of an electrical failure, a tank full of already
heated water is not available, on standby, as would be with a hot-water
tank system. Another could be dependent on the affected electrical
power utility—tankless electric units draw more instantaneous power
than tank water heaters because water must be heated quickly to the
desired temperature. If electric rates include a demand charge, operation could be relatively expensive.
PLUMBING INSPECTION
It’s likely that the plumbing in a new house will be put together satisfactorily from a technical viewpoint because local codes usually
specify that licensed plumbers must perform the work, and all of that
work must then be inspected and certified. But no matter what the situation is with your house, it’s still up to you to determine if the plumbing is installed in a fashion that you feel is adequate. Here are some
guidelines to help you evaluate your plumbing system:

3. Pipe Insulation
Bare pipes do not conserve energy, so they should be insulated.
Insulating cold-water pipes prevents cooling the warm air around
them during winter, which can cause a heating system to run harder
than necessary.
Insulating hot-water pipes is useful year round. During late spring,
summer and early fall, pipe insulation will prevent the heat from
the hot water inside the pipes from radiating and warming the surrounding air, which forces the air-conditioning system to run more
often. Insulating hot-water pipes also helps prevent hot water in
the lines from cooling off before it reaches its destination faucet
or appliance.
For pipe insulation, consider 3⁄4-inch-thick-wall preformed pipe
insulation tubes, some constructed of flexible rubber or polyethylene foam. These tubes can be purchased in bulk, or by the piece,
often 3- or 6-feet long, pre-slit and self-sealing.
Make sure that whatever type you choose is rated to safely handle
the highest temperature your system can produce. If the insulation
PLUMBING
PLUMBING CHECKLIST (Continued)
✔✔✔✔✔
is not suited for the application, the insulation could deteriorate or
even catch fire. Insulate bare steel-jacketed burst-proof hoses with
flexible pipe-wrap insulation with 3⁄4-inch-thick walls.
4. Miscellaneous Plumbing Points
You should be able to conveniently turn off the water or gas supply
pipes to each plumbing fixture in the house with shutoff valves
(Fig. 17.9).
A neat way to arrange the plumbing needed by the clothes washing
machine and laundry tub is to have the plumber install an in-thewall-plumbing box (Fig. 17.10). This box will dress up the installation and provide protection to any plaster or drywall that might be
placed behind your laundry area. It’s a good method to achieve the
plumbing compactness mentioned earlier. All of the faucet, supply,
and drain piping is conveniently tied together. A laundry room
clothes washing machine will be safer and more energy efficient if
insulated steel-jacketed burst-proof water supply hoses are used.

Make sure that piping run through the basement does not “break

Include enough sill cocks. A sill cock is nothing but an outside cold
water tap for lawn watering, car washing, and other outdoors use
(Fig. 17.11). A typical dwelling should have at least two of them,
F I G U R E 17.11

PLUMBING
PLUMBING CHECKLIST (Continued)
✔✔✔✔✔
and very large houses as many as four—so you needn’t rely on
excessively long and unwieldy garden hoses. Have the sill cocks
staggered around the house with one near the driveway. In coldweather locations where freezing occurs, sill cocks should be of the
freeze-proof variety to protect your exterior faucets from freezing
and rupturing. A freeze-proof outside faucet having a long stem
shuts water off a foot or two back within the house, where things
stay warm and above freezing.
Locate a sill cock or water faucet in the garage, preferably on an
inside wall bordering the heated part of the house.
Insist that single-unit bathtubs or shower stalls be installed while
the house is being framed for a more custom built-in look.
Even if you’re not including a basement bathroom with the initial
construction, it’s a good idea to include a “service stub” or connection arrangement for one sink, one toilet, and one tub/shower unit,
so they can be easily installed later.
Vinyl, ceramic tile, and wood flooring should be installed in rooms
that will receive plumbing fixtures. You’ll have a much neater looking floor if these materials are laid down first. If carpet is the
selected floor covering, the carpeting underlayment should be
installed before the plumbing comes through, then the carpet itself
can be laid after the fixtures have been set.
To prevent cluttering up the appearance of the front of the house,
have waste vents exit through the roof at the rear of the house.
All roof stacks should be made of galvanized or other nonrusting
metal or material.
A floor pan should be installed under a clothes washer if the
washer is located upstairs.

9. No scratches, dents, or chipped surfaces on appliances.
10. Test the water heater drain valve. See if it opens easily and seals
shut when closed.
11. Operate the sump pump, the humidifier, the baseboard heat, and
all other plumbing components that may apply. Check for leaks.
12. Try all outdoor spigots. Make sure they close easily and completely.
13. Check that isolation valves are tagged as to what they shut off.
Test the isolation valves, with the system activated, to see that
they hold. Make sure with hot water heaters and boilers that the
manufacturers’ instructions are followed.
14. If the home has natural gas, ask the utility company to test or
“sniff” the gas lines, gas appliances, and areas in which those
components are present for leaks, loose fittings, and other problems. Many utility companies will do such a check as a complimentary safety service.
PLUMBING
1. All piping must be well supported. Nothing should just hang there,
wobbly or vibrating when liquids and waste materials pass
through.
2. Pipes should run parallel to inside wall studs. If any pipe runs parallel to an exterior wall stud, make sure insulation is arranged
between the pipe and both the interior as well as exterior part of the
wall.
3. Check to see if the plumber installs the correct number of shutoff
valves and cleanouts as called for in the prints.
4. Before the walls and floors are closed up by the contractor, the
rough plumbing must be inspected by the municipal inspector. You
should also make a mental note (or drawing) of what’s getting covered up. Check that all water piping has been insulated.
5. The regular plumbing lines should be water-tested and inspected
for leaks, and if there’s a gas line, it must be subjected to pressure
leak tests as provided by the building code.
6. One of the most obvious ways to conserve resources and energy is
to prevent leaks. A faucet that leaks hot water wastes both. That’s
why you should select only faucets that come with a strong warranty. The extent of coverage specified is a good indication of the
manufacturer’s quality standards. For a top-notch faucet, look for
an all-inclusive warranty, one that applies to all of the parts as well
as to the outside finish. Consider washerless, drip-free faucets as
desirable alternatives to old-fashioned units with washers and
seals—the main reasons for troublesome leaks.
7. Request outside faucets: one in the garage (on a warm wall), one at
the home’s front, and two at the back to allow simultaneous lawn
sprinkling, car washing, or garden watering.
➤➤➤➤➤ POINTS TO PONDER
1. The time and effort you spend planning the location of plumbing fixtures is the most important part of their installation.
2. A major consideration is where to position the water heater,
and how to keep as much of the plumbing as possible concen-

trated in one three-dimensional area (from basement or lowest
level to top level) of the home.
The plumbing should be planned, if possible, so waste water
and materials flow by gravity alone.
Drain a few gallons of water from the water heater tank at least
once a month. At the same time, check the tank’s pressure valve.
Know where plumbing shutoff valves are. The contractor
should label each valve as to what it shuts off. Operate each
valve several times a year to keep them in working order.
All piping must be well supported to prevent wobbly or “hammering” lines.
For maximum energy savings, insulate water heater tanks (following the manufacturers’ instructions) and water lines. Install
water heaters near the highest hot-water demand areas to reduce
wasted energy from running the heated water long distances.
When planning your landscaping, keep large trees and large
shrubs from being planted over septic tank leaching fields, and
also avoid, if possible, connecting nonessential home wastewater streams to a septic system. Runoff from gutters should be
channeled elsewhere, as should discharge water from swimming pools and sump pumps.
If a gas water heater is located in a garage, make sure it’s raised
off the floor so when the pilot ignites the gas burners it doesn’t
cause any floor-hugging gasoline fumes from a lawnmower or
auto to explode.
Whenever you have the option, elect water-saving appliances
such as low-demand toilets, smaller bathtubs, and low-flow
faucets and showerheads.

HOW TO BUILD IT
THE POWER SUPPLY
The minimum power supply recommended for most houses today is
a three-wire 240-volt, 200-ampere service, especially if the house is
larger than 3,000 square feet, if heavy-draw electric appliances such as
electric cooking ranges or clothes dryers are planned, or if such features
as central air-conditioning and swimming pool pumps will be installed.
A good indication of the power supply available at any site is whether
two or three main wires enter the weatherhead fitting on the roof or side
of the house. If only two wires are present, the dwelling has 110–120 volt
power throughout. If three, then 220–240 is available at the meter.
The circuit box is where the main electrical service is split into separate circuits. There should be at least 12 to 15 circuits to handle the
electrical needs for most homes. The cover on the panel should be able
to be tightly closed, and the main wires entering the box should be
neatly and securely affixed to the wall. Home wiring must be
grounded properly. Proper grounding provides a path for electricity to
safely travel from a defective appliance, tool, outlet, fixture, or other

ELECTRICAL OUTLETS AND SWITCHES
The rule for electrical outlets is one duplex outlet for every 12 linear feet of wall, because lamps and household appliances usually have
6-foot-long cords. When a doorway comes between, the outlets around
it should be located closer than 12 feet apart or you might have to use
extension cords in that part of the room. Kitchen outlets are best
located above the countertop to handle appliances safely. A duplex
wall outlet for every 4 linear feet of kitchen counter space will do
nicely.
Here are some other guidelines:
1. There should be light switches at every entrance to every room,
and, for safety’s sake, at the top and bottom of stairs and at garage
and basement doors. These switches should be about 3 feet away
from the steps so that the user will not trip on or down the steps
while trying to access the light.
2. Insist on “intermediate-” or “specification-” grade outlets and
wiring. There are also “competitive” grades of cheaper quality for
only a minor difference in cost. Specification grade, the best of all,
is usually recommended for heavy-duty commercial installments,
ELECTRIC
but is worth the extra cost if you want top quality, particularly in
the kitchen and in all switches.
3. Wall switches should control overhead lighting. If a room has
more than one entrance, install double- or triple-pole switches so
these lights can be turned off and on from each doorway.
4. If a room has no overhead lighting, such as a living room or family
room, wire at least one duplex outlet to a wall switch so a lamp
that’s plugged into the outlet can be turned on and off at the switch
on a wall near the room’s entrance.
5. Include at least three outside electrical outlets (two in front, one in
back), and for a large, sprawling ranch home, four. They should be
equipped with ground fault circuit interrupters for protection
from the electrical hazards posed by wet lawns and driveways, as
well as a weatherproof cap that covers each receptacle.
6. Install ceiling outlets in the garage for automatic garage door openers even if you’re not planning to use openers at first. If you decide
to add such a convenience later, you can do it without having to
spend a hefty price for a service call.
7. Be certain to plan several receptacles in the garage for power tools,
an extra freezer, a vacuum cleaner, and other items.
8. All ceiling fixtures such as lights and fans must be securely fastened to the house framing structure and not dependent on the
outlet for anchoring.
9. There should be at least one ground-fault circuit interrupter
(GFCI) duplex safety outlet above each bathroom vanity top for
hair dryers, electric shavers, and other personal care appliances.
Such outlets will help prevent shock.
10. All receptacles should be the three-hole grounded type. These are
much safer than the old two-hole ones. If an appliance becomes
faulty, the current will pass through the third wire (the ground
wire) in the receptacle rather than through you.
11. Make sure you allow for a sufficient number of outlets throughout
the home, especially for plugging in and unplugging electronic
equipment. Many of today’s home electronic items use electricity
even when turned off—they go into “stand-by” mode so that they’ll
443
444
HOW TO BUILD IT
instantly ready when needed. This stand-by energy loss is sometimes referred to as “leaking electricity.” Consider that to save this
type of energy from enlarging energy bills, try to remember to
unplug home electronics and appliances when they’re not in use.
12. It’s easy to overlook the basement when planning for outlets. Consider that refrigerators, freezers, hand tools, vacuums, dehumidifiers, sump pumps, and extension cords all require electricity.
13. Locations of certain light switches and outlets you want in special
places can be marked in advance with chalk.
LIGHTS AND LAMP WIRING
1. Wire for overhead lights in the dining area, kitchen, kitchen sink
and counter, laundry room, bedrooms, bathrooms, hallways,
garage, and basement.
2. Avoid putting recessed lights in ceilings with unheated space above. They
can’t be properly insulated and will
leak air badly. Recessed lights should
be the Insulated Ceiling (IC) type. Confirm from the manufacturer that the
units will not become hot enough to be
fire hazards.
3. Include recessed lights in all closets,
with wall switches mounted outside the
closet near the closet door (Fig. 18.1).
Even shallow closets having bi-fold
doors will need lighting on occasions.
F I G U R E 1 8 .1
Closet recessed lighting.
4. Consider some outside spot or floodlights to provide illumination for general use of the yard and for security
reasons. Ideally, some yard lighting
should be controlled from the master
bedroom as an additional security
measure.
ELECTRIC
5. Make sure there’s wiring for lighting at the front and back doors and
wherever someone can enter the house, with convenient switching
at those locations. Lighting should be wired near the main electric
service panel so you can see the circuit breakers and their labels
without using a flashlight.
SURGE PROTECTORS
A power surge may not sound dangerous, but if it strikes your PC,
TV, or other piece of electronic equipment, it can cause expensive
problems. The average home gets almost a dozen surges from lightning
every year—power surges that can damage electronic microchips. And
lightning is not the only source of high-voltage surges. Local businesses and utility companies with electrical equipment going off and
on can also help create potentially damaging power surges.
These surges may not damage an electronic device right away, but
the cumulative effects can definitely ruin equipment over time. Each
surge results in an electrical “hammering” that wears and tears at the
weakest parts of the electronics, eventually causing failure. Power
surges come from both outside and inside a home, for numerous reasons, and can even travel through phone and cable television lines.
The remedy? In addition to individual outlet plug-in surge protectors, whole-house voltage surge protectors are available for installation
with a home’s main electrical system. Such a combined two-stage
method protects electronic equipment from almost anything short of a
direct lightning strike.
Whole house surge protectors help protect every television, phone,
computer, modem, microwave oven, programmable thermostat, stereo,
fax machine, security system...the list goes on and on. Some whole-house
surge protectors are installed at the circuit breaker box, while others are
engaged at the electric meter—generally installed by the supplying utility
company. These surge protectors use very little energy and can literally
save hundreds of dollars in appliance repair and replacement costs
because modern appliances are often operated through delicate electronic
controls that can be instantly damaged by high-voltage surges.
With less power spikes and surges traveling through the home,
appliance energy-efficiency capabilities and life expectancies are
445
446
HOW TO BUILD IT
increased; even simple light bulbs will last longer and burn brighter.
The surge protectors should have monitor lights that indicate if the
units are working. Before specifying whole-house surge protection,
discuss the options with your builder or electrical contractor.
ELECTRICAL INSPECTION
Here are some wiring features to watch for as the house nears the
plaster/drywall stage, and how the electrical inspection proceeds:
1. See that in exterior walls, cables installed horizontally run along
the top of the bottom plate. This provides the least interference
with wall insulation. Most electric cable is sufficiently flexible to
comply.
2. Be careful how electric wiring is installed in bathrooms. It should
not be run through the area around the bathtub. Wiring should also
stay clear of places where long screws may be used to fasten shelving, soap dishes, or towel racks to the wall.
F
OCUS
HOME CONTROL SYSTEMS
Individuals with busy schedules can employ relatively sophisticated
home control centers by simply touching bedside controls or clicking the
mouse of a personal computer. These units can operate various home
equipment functions even from remote locations through code numbers
sent via Touch-Tone phone lines. Homeowners can better manage their
heating, cooling, and ventilation systems to save money and increase comfort. These electronic units can control functions such as the following:
■ Setting/checking security systems before leaving the home or
retiring at night
■ Setting lawn sprinklers for the next morning or evening
■ Automatically turning off/on house or Christmas lights
■ Setting what time a VCR/television should wake you up or record a
program
■ Automatically starting kitchen or other appliances
ELECTRIC
3. Wires should not be placed too close to any plumbing to avoid damage from the plumber’s propane torch.
4. After all the rough wiring is completed—known as the “roughing
out”—and checked over, the electrician will contact both the
Underwriters Laboratory inspector and the local building code
inspector who will inspect everything and, if satisfied, will issue a
certificate and notify the utility company. The utility company will
then send a representative to connect power to the house.
5. The electrician can now wire all the outlet box receptacles as soon as
the walls are insulated and covered. To finish this work, the electrician must know how you plan to complete the walls so that the boxes
can be set to project the right amount through the finished walls.
SPECIAL ELECTRICAL FEATURES
Remember to give some consideration to the following features:
1. Noiseless, no-click light switches. There are also silent touch-button switches that require only slight finger pressure. There are flatplate models that are set flush against the wall. Slight pressure on
the top turns a light on, and pressure on the bottom turns it off.
2. Ivory, colored, metallic, and other decorator switchplates are
available instead of the standard plastic brown, off-white, or tan
models that might clash with your decor. Electrical and lighting
suppliers carry them in a wide variety of models and materials.
These unique switchplates can give your house an interesting finishing touch overlooked in most dwellings today.
3. Dimmer controls enable you to adjust lighting intensity up or
down according to your needs. Illumination in a room can be
dimmed to a candlelight glow for a dinner party, kept subdued for
television watching, or turned up brightly for reading. Dimmers
are used chiefly for living and dining rooms, but can also be used
in a bathroom night-light arrangement.
4. You can have built-in automatic switches that turn on the closet
lights when the doors are opened, and then turn them off again
when the doors are closed, similar to the refrigerator interior lighting setup.
447

5. Remote-control lighting is surprisingly simple to install. It can
permit you to turn indoor and outdoor lights on or off from a central location such as the kitchen or master bedroom. A remote
kitchen switch can control front door or garage lights, for example
A control panel next to your bed can eliminate that final tour of
your house and grounds every night to turn out all lights.
6. Electrical snow-melting panels are available for sidewalks and driveways, and electrical snow-melting wire strung along your roof
gutters will prevent the accumulation of dangerous snowdrifts and
icicles on the roof slopes and gutters (Fig. 18.2).

protection against shocks and help prevent the possibility of electrocution in a bathroom. A ground fault is
a partial short circuit in an electrical
device. A person can be the electrical
ground (electricity will travel from an outside source through the person and into
the ground) when using an appliance or
tool in a damp or wet area such as a bathroom, laundry room, basement, garage, or
backyard. The partial short circuit allows
a small amount of electrical current to
flow through the individual’s body—a
condition that could be harmful or even
fatal. Regular household appliances work
by drawing power from one side of a wall
receptacle through one prong on the plug,
and returning it through the other prong to
the other side of the receptacle. If the GFCI

Lighting
A
long, long time ago, before humans discovered how to use fire,
when it got dark, it got dark. There were no switches to flip on, and
no battery-powered flashlights to illuminate pathways. Once we
mastered fire, we not only increased our comfort, safety, and
gastronomical enjoyment, but the light we gained supplied us with
more time to constructively work with.
The first lamp could easily have been a lit pool of fat drippings that
shimmered in a shallow depression near the glowing embers of a cave
campfire.
Then clay and stone lamps came onto the scene—little more than
saucer or cup-shaped receptacles for oil, grease, or tallow. They were
either open or covered, with a carrying handle on one side and on the
other a small trough or gutter in which a wick rested. This simple lamp
persisted for about 10,000 years, resisting change even into the eighteenth and nineteenth centuries, when people were still using dangerous iron lamps that burned disagreeable-smelling whale oil.
Throughout the ages, light has always been something sacred to
humans. It has been a symbol of religion, of ideas, of knowledge and
understanding. It has enabled us to take advantage of our most important sense: sight.
Lighting in these days, however, often takes a back seat. People will
frequently buy lights because they fancy the fixtures, not the effects
453

454
HOW TO BUILD IT
those features will provide. When you think of it, that’s kind of silly. It’s
like buying food for only its looks, or for how it might conveniently fit
into a refrigerator or freezer, with no regard to taste or nutritional value.
There’s often little advance planning for lighting. While homeowners pride themselves in knowing the last little detail about stereo systems, kitchen ranges, or video players, the lights that illuminate their
private worlds are completely taken for granted. That’s too bad,
because precise lighting can create a variety of moods within a room
and can help exaggerate strong points while downplaying shortcomings. Lighting can increase efficiency in work areas. Consider how
important lighting is to theater and dance. What show, what film, what
live performance have you ever seen that didn’t include strategic lighting as a major part of its overall effect? Consider museums and art galleries, and how they can make their showcase works stand out by
merely lighting them properly.
The same principles hold true for lighting in home use, in the average household. Unfortunately, most people are afraid to make advance
plans they feel might be too radical and difficult to change. Nothing
radical is needed, however, to lend a home a pleasant lighting scheme.
It doesn’t take many built-in lights to add a distinctive touch.
TYPES OF LIGHT SOURCES
Sunlight
Sunlight, or “natural” daylight, as it’s sometimes called, is plentiful—at least during the day—and free. Natural light can lift a person’s
spirits, can help display colors more accurately, and provides excellent illumination for reading or for doing intricate tasks.
People and plants function better in a natural light-filled environment. Of course, sunlight intensity can be somewhat reduced by
clouds, weather, foliage, plus the seasonal position and tilt of the
Earth’s axis. Days get longer and shorter and longer again, and some
sunlight is considerably stronger in certain locations and places.
Unfiltered sunlight, or rays strengthened and concentrated by certain
types of glass and windows, can send ultraviolet and other light waves
into the home to discolor and fade furnishings and to dry out and burn
skin on people, pets, and plants.
LIGHTING
455
Naturally, the chief source of natural light is glass in windows, skylights and doors. In earlier editions of this book, discussions about
skylights were presented only in the chapter about windows, where
they were mentioned regarding their roles providing ventilation and
natural light. Numerous advances in skylight technology, however,
made it far more logical to include some information in this, the lighting chapter, as well.
Electric Lighting
There are only two major kinds of electric lamps or “bulbs” as
most people call them: incandescent-filament lights and fluorescent
lights.
INCANDESCENT-FILAMENT LIGHTING
The first practical incandescent-filament lamp was perfected by
Thomas Edison in the late 1800s. An incandescent lamp produces
light when its filament (usually made of tungsten) is heated by an electric current to a regulated temperature, at which point it glows and
emits the amount of light it’s engineered for (Fig. 19.1). The quality of
light from incandescent-filament bulbs is warm in color and gives a
friendly, homelike feeling to interiors. Beneath incandescent lights,
colors such as oranges, reds, and browns are enhanced, while the cool
colors such as blues and greens are subdued.
These bulbs provide a source of light that can be focused or
directed over a restricted area if desired, and because most incandescent household bulbs have the same
size base, the lighting from fixtures or
lamps can be increased or decreased
within limits by changing to bulbs of different wattages. Most types of incandescent lights are less expensive than
fluorescent types. And the incandescent
lighting fixtures themselves are generally
less expensive to purchase because they
require no ballast or starter—a part of a
light bulb that provides a high voltage for
F I G U R E 1 9 .1
starting the bulb and a low voltage for
running it.
Incandescent-filament light.
456
HOW TO BUILD IT
FLUORESCENT LIGHTING
Fluorescent bulbs operate by an entirely different principle.
They’ve typically been long and tubular in design, either straight, circular, or angular in the case of neon signs used for advertisements.
They’re coated on the inside of the glass with phosphors, substances
that give off light when subjected to ultraviolet radiation generated by
a low-pressure electric charge. The low-pressure electric charge is regulated by the starter or ballast that forces the charge through a mercury
vapor inside the bulb (Fig. 19.2).
Fluorescent bulbs offer greater lighting efficiencies, up to three or
four times as much light per watt of electricity as incandescent bulbs
have. They’ll also last from seven to ten times longer, largely due to
their cooler operating temperature range. Hot-burning incandescent
lights, by their very nature, burn themselves out more quickly.
Fluorescent bulbs provide lines of light and are excellent choices in
work areas where light coming from several angles is needed to effectively eliminate bothersome shadows. These lines of light are also frequently used over mirrors, kitchen work surfaces, in window
valences, corners and covers, and other architectural features. Due to
their long life spans, fluorescent bulbs are favorites in places that can’t
be conveniently reached for bulb changing. Circular fluorescent tubes
have traditionally been used in high kitchen ceilings, for example.
When considering their use, remember that some fluorescent bulbs
aren’t as quiet as incandescent lights. Most fluorescent models produce faint humming sounds, which admittedly are noticeable only if a room is
library quiet or if you’re listening for the
noise. A newer wrinkle to the lighting
scene has been the emergence of smaller,
more compact fluorescent bulbs or lamps.
Compact Fluorescent Lights
F I G U R E 19 . 2
Fluorescent light.
As a general guideline, although they
can cost many, many times what a comparable incandescent bulb costs, compact
fluorescent light bulbs are about four times
more energy efficient, provide equivalent
illumination for considerably less wattage,

produce less heat, and last up to 6 to 10
times longer. Many take the form of coiltype spiral bulbs that will fit in traditional
incandescent fixtures (Fig. 19.3). Others
are manufactured in straight, longer styles
that may not fit traditional fixture shades
or globes designed for incandescent bulbs.
For sure, compact fluorescents are great
for hard-to-reach places where changing
bulbs may be both an inconvenience and a
safety issue. When planning your lighting,
remember that not all compact fluorescents are equal. Some are constructed with

cheaper models with this kind of accompanying ballast tend to flicker at startup,
and may buzz. When planning for compact fluorescent fixtures, consider fixtures with built-in ballasts that take pin-based replacement
bulbs (Fig.19.4), which will save money because you won’t have to
replace the ballast within the bulbs every time you change a bulb.

HOW TO BUILD IT
Just be sure you know how much the replacement bulbs will cost,
where to buy them, and that pin-type fixtures will not accommodate
standard screw-threaded incandescent bulbs. Also be aware that many
compact bulbs cannot be dimmed with dimmer switches. If you want
to dim one, you’ll need to purchase a bulb designed for dimming. If
applicable and desired, make sure the same bulb can be used with
photo sensors, electronic timers, or motion detectors. Fluorescent
bulbs come in numerous makes, models, and sizes, including threeway and floodlight styles.
Some, however, have certain restrictions on what they should be
used for, such as: only indoor use, outdoor use, low-temperature use,
cannot be installed within a glass globe, or cannot be installed in an
inverted position. Compact fluorescent lights are components that are
constantly being improved, and you can expect numerous advancements in the near future.
Skylighting
Again, you’ll find a separate discussion of skylights in the window
chapter. Although it’s hard to review the same subject here without
some overlap, there are several important points worth re-reviewing:
A skylight is basically a casement window mounted in a ceiling or
section of roof framing to provide natural daylight, and sometimes ventilation, so the need for additional active daytime electric light, and
possibly powered ventilation, is reduced. Since hot air naturally rises,
opening a vented skylight will exhaust such heated air and create a
comfortable breeze inside the dwelling without relying on air conditioning. Some models are fixed in place, and do not open or vent at all.
On skylights that do open or vent, control options range from a
manual crank, to an electric motor operated by sophisticated electronic and/or hand remotes.
Many skylights come with laminated or tempered glass having lowe and tinted coatings that effectively control heat transmission and
ultra violet radiation. Compare U-value, heat transmission, and light
transmission rates of all skylights you may consider for your home.
Sunlight Tubes or Tunnels
Sunlight tubes or tunnels are, essentially, highly reflective cylindrical skylights that run from the roof down into an interior room or
LIGHTING
space (Fig. 19.5). These natural sunlight
skylights are complete roof-to-ceiling systems for efficiently bringing natural sunlight into the home.
In frequently used rooms requiring
ongoing lighting, a sunlight tube or tunnel
offers natural lighting that saves turning
on electric lights every time you enter, say,
a bathroom, kitchen, or other room where
such a natural lighting system is installed.
There are lots of makes and models available, but they all operate under the same
principle. Sunlight enters through a clear
acrylic plastic or similarly made dome on
the roof.
Acrylic does not yellow from sun exposure, and it naturally filters out some of
the damaging ultraviolet rays from the
sun. In its domed shape, it is very resistant
to breakage, even from hail. Rain will usually be enough to keep it clean. Some
domes incorporate a prismatic lens, like a
“fly eye,” that helps bend and collect lowangle or early morning light and late afternoon light down into the
tube or tunnel. Some units provide interior seals and a double-insulated diffuser lens component that creates insulating dead-air pockets
similar to those of a thermal pane window.
The insulation rating on some models is as high as R-22. Collected
sunlight travels from the roof dome through a rigid or flexible tube or
tunnel. The rigid tube or tunnel is lined with one of several types of
silvery, highly reflective linings of aluminum or equally good quality.
A rigid tube is fine for passing through an open attic; the fewer bends
(elbow joints), the better, because even though the tube is highly
reflective, some light intensity is lost each time the light bounces back
and forth inside the tube. Flexible tubes or tunnels employ sturdy construction that can be easily bent around obstacles such as chimneys,
furnace ducting, beams, and other construction components, without
using elbow joints. The captured sunlight, after being transported

HOW TO BUILD IT
down the tube or tunnel, is then diffused into a room or space through
another prismatic diffuser lens.
On sunny days, this natural skylight can easily provide the equivalence of between 600 to 700 watts of incandescent light. Even on
cloudy days there is still enough natural light to approach the illumination level of a 100- or 150-watt bulb, and what’s more, on nights
with a clear sky and full moon, an out-of-this-world moon glow within
the room is not out of the question.
HOME LIGHTING USES
Few homes will rely on one or the other type of bulb exclusively.
Most dwellings employ a combination of incandescent and fluorescent fixtures. What follow are three different ways in which both types
of lights can be used in modern dwellings.
General or Background Lighting
General or background lighting is a low level of illumination required
for general living activities. It’s the level of lighting provided by ceiling
fixtures such as overhead lights in a bedroom, or from lighted valances
(shields affixed to the wall that direct light from a source behind them
upward, downward, or both ways), coves, cornices (shields affixed to the
ceiling that direct light from a source behind them downward), and wall
lighting, or portable lights in groups of three or more that cast relatively
low but adequate levels of light throughout a room.
Local or Task Lighting
Local or task lighting is the light you want focused on relatively
small areas or limited areas used for specific activities such as reading,
playing cards, typing at a computer keyboard, playing billiards,
sewing, painting, shaving, cooking, and eating. These are the lamps
and fixtures people are most familiar with, including floor, desk, and
table lamps, and other lighting arrangements such as recessed ceiling
downlights in a bathroom to illuminate a bathtub or hand basin.
Accent or Decorative Lighting
Accent or decorative lighting comes from fixtures planned to create
certain moods and atmospheres, plus fixtures designed and positioned
LIGHTING
to emphasize artwork, plants, and any other items important to a person’s lifestyle or interior decor. Many different kinds of fixtures and
bulbs can be used in creative ways here, limited only by the owner’s
imagination. Spotlights, floodlights, all sorts of decorative lights, and
even candles, will create a host of effects.
While planning your home you have to decide how much of each
of the lighting types you need. Then look through designer books,
magazines, and lighting sales literature for ideas, and, if possible, visit
actual houses that pay attention to lighting schemes. It doesn’t take
many well-placed lighting built-ins for a house to be considered
unique, and such a home will gain a special quality not found in the
vast majority of dwellings that treat lighting merely as a necessary
afterthought, not a part of the house to be carefully planned for maximum effect.
With general lighting, the light rays are usually diffused over a
wide span. This diffusion is best accomplished by translucent glass
or plastic. In a room in
which the light is completely diffused, it will be
coming from all sides,
either directly or indirectly
(bouncing off other surfaces) including the floor
and ceiling, so no shadows
are cast.
Dimmers can be useful
to increase control over a
variety of lights by taking
charge of the voltage or current applied to the bulb or
tube, thus giving a full
range of light intensities.
Dimmer Lights
Dimmer light switches
that come with intensity
slide on and off controls
(Fig. 19.6) allow you to

461
462
HOW TO BUILD IT
simply turn a light on or off without setting or resetting the dimmer
intensity level each time. By operating lights at less than their maximum output, energy savings can be realized. Dimming can also add an
interesting mood to a room while quietly extending the life of affected
light bulbs. Light bulbs dimmed just 10 percent on a regular basis are
estimated to last about twice as long as a bulb burned at full brightness. For flexibility, dimmer switches are available that allow dimming the same light fixture from multiple locations.
Under-Cabinet Lights
The kitchen is one room to consider for the installation of low voltage under-cabinet lighting that will make counters brighter and safer at
a savings compared to operating overhead fixtures that illuminate the
entire room. Because basic kitchen lighting can place the fixture at the
center of the ceiling, cooks working at counters frequently find themselves working behind their own shadows. This will make food preparation difficult and sometimes even dangerous. Under-cabinet lighting
gives an effective lighting output that can be focused directly on tasks
at hand. Fixtures are available with swiveling heads that allow home
cooks to pinpoint illumination exactly where it’s desired.
Automatic Light Switches
Also called motion-activated light switches, these “automatic” controls (see Focus on Motion Detector Lighting) are typically activated by
a sensor that detects a moving object that emits heat, such as a person
or animal. When the activating creature leaves the room, the light will
automatically turn itself off, preventing lights from being left on unintentionally. These switches should also have electric eyes so that the
lights do not come on if there is already enough daylight present. Units
having adjustable daylight sensors for this purpose will allow the level
of darkness to be preset for when motion will begin to turn the lights
on. For rooms where you spend a lot of time in the evening, watching
television or reading, you can install a light control that gradually
brightens the lights as night falls. It senses the current conditions and
maintains a preset desired brightness level within the room. Automatic light switches can be great indoors for bedrooms, kitchens, stairwells, closets, garages, attics, and laundry and utility rooms. It’s nice

MOTION DETECTOR LIGHTING
Motion detector lighting can provide both convenience and cost-efficiency. No more fumbling for light switches when entering a closet,
garage, basement, attic, or laundry room—especially when your arms
are full of groceries, tools, or laundry. Feel more secure when you come
home to an illuminated entryway, deck, or patio (Fig. 19.7). Some units

463
464
HOW TO BUILD IT
can be adjusted to sense motion up to 50 feet away and within a 120degree radius. It’s also convenient for visitors to park their vehicles
outside in a well-lit driveway, and to approach the home’s entrances on
illuminated walkways. Motion-detecting units can come with solar-powered security lights. The solar panels are normally tethered with long
cords so the panels can be located in a remote place. Solar units are
also available with amorphous collectors that make use of energy present in low-light levels during morning, dusk, and even overcast and
rainy days. Heavy-duty batteries allow units to work in below-freezing
temperatures.
Indoors, why allow lights to be on for long periods of time, especially
if you have children who are constantly forgetting to turn them off?
Motion-sensing wall switches exist that activate when a person enters
a room or area. Lights can easily be “tuned” to stay on for 1 to 10 minutes after no motion is detected. Sometimes a wide field of view for a
sensor works best for a particular situation, and other times a narrow
field is desired. Motion-detecting units are available for both. Installation of these convenient components can be specified along with the
main electrical system.
or laundry. The electricity savings from not leaving the lights on by
accident will quickly pay back the cost of the switch, and when children are involved, the savings can be even greater.
LIGHTING TERMS
Lighting terms are constantly being tossed about by various experts
and publications. Here are a few that you
should be familiar with:
■ Semi-direct—light is directed 60 to 85
percent downward.
■ Semi-indirect—light is directed 60 to
85 percent upward.
■ Recessed—lighting

flush to a ceiling, wall, or other surface
(Fig. 19.8).
LIGHTING
465
■ Valance—light sources shielded by
a panel attached parallel to a wall,
usually employed across the top of a
window. Valance lighting provides
illumination both downward and
upward, unless the valance possesses a top (Fig. 19.9).
■ Indirect—a system in which over 85
percent of all the light is cast
upward toward the ceiling.
■ Direct—over 85 percent of all the
light is cast downward toward the
floor.
F I G U R E 19 . 9
■ Accent—directional
lighting to
emphasize a particular area or
object (Figs. 19.10 and 19.11).
■ Cornice—light sources shielded from direct view by a panel of
wood, metal, plaster, or diffusing plastic or glass parallel to the
wall and attached to the ceiling, and casting light over the wall
through direct or downward lighting (Fig. 19.12).

General diffuse lighting.
LIGHTING
■ Cove—light sources shielded by a ledge and casting light over
the ceiling and upper wall, usually through indirect or upward
lighting (Fig. 19.13).
■ General diffuse—almost an equal amount of light produced in
all directions, such as the light emitted from a suspended globe
(Fig. 19.14).
■ Luminous—a lighting system consisting of a false ceiling of dif-
fusing material with light sources mounted above it (Fig. 19.15).
■ Track—one electrical outlet supplying a number of separate fit-
tings that can be positioned anywhere along a length of electrified track. It’s very versatile for ceilings or walls, with vertical or
horizontal tracks (Fig. 19.16).
■ Wallwashers—when installed about 3 feet away from a wall,
wallwashers will light up the wall evenly from top to bottom or
bottom to top, without spilling or wasting light away from the
wall into the room. Angled closer to a wall of paintings or art
groupings, wallwashers will splash light onto varying surfaces,
leaving interesting shadows contrasted in between.
■ Downlights—round or square metal canisters that can be
recessed into a ceiling, semi-recessed, or ceiling mounted to
cast pools of light on the floor or on any surface below them.
They can be a spotlight, a floodlight, or an ordinary bulb. A
spotlight will throw a concentrated circle of light. A floodlight
will cast a wider, cone-shaped light. An ordinary bulb will provide soft, diffuse, all-over lighting.
■ Uplights—fixtures put on the floor, behind sofas, plants, or
other appointments, under glass shelves, and in corners where
they will lend a beautiful dramatic accent, bouncing reflected
light off ceilings and into the room, creating moods that could
hardly be imagined possible by day.
Exterior Lighting Considerations
■ Consider solar powered security lights (Fig. 19.17), where solar
panels collect free natural light during the day and store it as
energy in rechargeable batteries. No exterior supply wiring is
needed. For motion-sensing models, at night, a halogen bulb

turns on automatically when any
motion is detected and remains on a
certain length of time—30 seconds
or so—after the motion stops. Other
models are triggered by timers or
automatic photocell electric eyes set
to specific darkness levels (that turn
on automatically at night, and off in
the morning).
There are units available that
work by solar panels so the light
itself can be located in a shady area if
need be. Some can function in temperatures reaching 40 degrees
Fahrenheit below zero. You can aim,

switches, and weatherproof housings
seal for protection against the elements. Some units will operate
for nights without an intermediate charge. Different styles of
solar-powered lights can solve a variety of specific lighting challenges. Wall-mounts, hanging units, column-mounted coach
lights similar to a lamp post, pagodas, and tier lights that are wallmounted or ground-supported cover most situations.
For entryways, decorative lantern units are common
choices. Many have adjustable motion sensitivity and manual
override so you can activate the light from a standard wall
switch. Motion-sensing flood lights directed at rear and side
entranceways or walkways are recommended by many security
experts. Even on cloudy days, built-in batteries will keep them
working. At dusk, an electric eye automatically switches on an
accent amber LED. When motion is detected within about 20
feet of the light, a bright halogen bulb comes on for about 3 minutes to scare away unwanted visitors. Remember that the key
factors to consider when selecting a motion-sensing light are the
sensitivity range and field of view. Those two factors determine
the area of security coverage for an individual light fixture.
■ To assist evening delivery persons, visitors, emergency service
providers, and others, solar-powered house number lights are

available. Numbers 4 inches high illuminate at night and can be
clearly seen from the street. They need only a couple hours of
sun during the day and are completely weatherproof. Mailboxes
with solar-powered lights also use rechargeable batteries that
can be activated at night by a remote control feature that allows
you to turn on the lights from inside your home.
■ Hanging garden lights are another outdoors option. They come
with an adjustable height hanging hook. They’re ideal for illuminating steps, walkways, entryways, porches, decks and patios.
General Lighting Considerations
■ Use lower-watt bulbs for nonworking spaces.
■ Choose light fixtures that are easy to access and clean. Remem-
ber that dirt absorbs light.
■ To get the most from your lamps, walls and ceilings painted
white will maximize the amount of reflection into the room.
■ Lighter color and shades of furnishings such as carpeting,
draperies, and upholstery will minimize the amount of artificial
light required by a room.
■ Mirrors spread light within a room. By strategically placing mir-
rors where they will not be blocked by furniture, illumination
can be spread and extended to where needed.
■ Selecting fluorescent-bulb fixtures over incandescent-bulb fix-
tures results both in energy savings and longer individual bulb
life. This becomes especially important with fixtures that illuminate from hard-to-reach areas inside garages, stairwells, foyers, attics, or anywhere you need a ladder to change the bulbs.
Standard 4-foot-long bulb fluorescent fixtures with reflective
backing and electronic ballasts are great for workroom, garage,
and laundry areas.
■ Bulbs having the Energy Star label, though they typically cost
more to buy, run with less pollution, less energy, and will last
longer.
■ Use lamps and other fixtures having three-way controls (for
bulbs having three separate wattage levels, such as a bulb for a
LIGHTING
table lamp set up as a reading light, with the brightest intensity
setting to read by). Three-way bulbs enable you to use the lower
settings when the brightest is not necessary.
■ When choosing night lights, consider 4-watt mini fluorescent or
electro luminescent models. Some use as little as a few cents per
year to operate. Some have auto-off features that will turn the
light off after 10 to 30 minutes; after 9 or 29 minutes the bulb
will blink twice—signaling that it is only 1 minute away from
turning itself off.
■ Have you ever been frustrated by children who leave closet
lights on forever? Then consider door frame buttons that turn on
the light as the door opens—similar to that of a refrigerator. As
the door is closed, it pushes the button in and the light turns off.
Of course, you’ve got to train those same children to keep the
closet doors closed, or install an automatic door closure.
■ To provide cost-effective security lighting while you’re gone,
consider electronic timer/light switches. The best ones enable
you to set different light schedules (six on/off times) for each day
of the week. Some even have random lighting schedules. Even
for just an evening out, it’s an effective strategy to have indoor
lights go on at dusk, or at other times while no one is home.
■ Remote control entry door locking and lighting controls allow
you to illuminate and unlock an entry door from as far as 30 feet
away, providing both security and convenience. This helps save
energy by eliminating the need to leave your outdoor lights on
all evening until you return, and allows you to use both hands
to carry items to the door, instead of using one hand for keys.
With the remote, you may need one less trip back to the car, as
well as one less opening and closing of the entry door. Each time
the door is opened, heated or cooled air can escape.
➤➤➤➤➤ POINTS TO PONDER
1. Built-in lighting—opposed to lighting fixtures simply added on
after the rooms are planned—will add a distinctive touch to
any home.
471
472
HOW TO BUILD IT
2. Fluorescent lamps offer greater lighting efficiencies than do
incandescent-filament lamps. Initially, setting up for fluorescent lighting is more expensive, but those expenses will eventually be recaptured with lower energy costs.
3. Fluorescent lamps—due to their cooler operating temperature
range—will typically last up to ten times as long as many
incandescent bulbs. That’s why fluorescent lamps should be
considered in places that can’t be conveniently reached for
bulb changing.
4. If absolute quiet is a major factor, such as in a small office or
library, remember that fluorescent bulbs aren’t as quiet as
incandescent light. Most fluorescent models produce faint
humming sounds. On the other hand, so do personal computers—and few individuals notice or complain about computer
background noise.
5. Most homes are constructed with plenty of general or background lighting such as overhead lights in bedrooms. Identify
places where local or task lighting will be needed and try to
plan recessed or track lighting units to focus on those areas.
6. Dimmer switches make sense wherever accent or decorative
lighting is installed. Dimmers increase control over lamps by
taking charge of the voltage or current applied to the bulb or
tube, thus allowing a full range of light intensities.
7. Make sure fixtures are rated for the bulb wattages you plan to
use in them. For example, avoid burning 100-watt bulbs in fixtures rated for only 60 watts.
8. If your children are notorious for leaving certain lights on all the
time, such as bright lights over a makeup table, consider putting
the lights on a 15-minute (or so) timer switch that will automatically turn off the lights unless the timer is manually reset.
9. Make sure all stairways have adequate lighting that’s controlled
by switches at both ends of the stairway.
10. Consider twice before installing fixtures in places that are
extremely difficult to access, such as in vaulted ceilings and twostory-high entrance foyers. At the very least, plan how the bulbs
will be replaced without the use of extra-long ladders. Also,
avoid putting recessed lights in ceilings with unheated space
above. They can’t be properly insulated and will leak air badly.
CHAPTER

Heating and Cooling
Y
ou could plan the most attractive and utilitarian home design
imaginable, locate it on a site with a breathtaking view, and furnish
it with the finest appointments, yet unless the temperature and
humidity within such a dwelling are maintained properly, the house
would be unpleasant to live in. Heating and cooling systems are
probably the hardest working components of any home, especially in
homes located in climates having temperature extremes.
For discussion purposes, heating systems can be broken down into
two topics: types of fuel, and types of heat production and delivery
systems.
TYPES OF FUEL FOR HEATING
There are six primary types of fuel available for home heating use:
electricity, fuel oil, gas, coal, wood, and solar.
Electricity
Electricity is readily available almost anywhere.
Advantages
1. It’s a clean fuel that leaves no residue to contaminate the house or
the atmosphere.
473

474
HOW TO BUILD IT
2. It requires no chimney to vent exhaust fumes and smoke.
3. It’s a fuel that can be depended on in the future because it can be
produced from almost any other type of fuel—gas, oil, coal, nuclear,
solar, wind, and hydro or water power.
Disadvantages
1. Its fuel rate charge depends on the local utility company.
2. Breaks in the main supply line could leave you and your neighbors
temporarily without supply.
Fuel Oil
Like electricity, fuel oil enjoys a comprehensive, efficient distribution that makes it readily available practically everywhere.
Advantages
1. If the oil fuel burner is routinely serviced and adjusted for maximum efficiency, fuel oil is a relatively clean source of combustion.
2. The supply is stored on the property. Once it’s in place there’s no
worry about it being cut off.
Disadvantages
1. It must be stored in a tank that’s usually located underground. The
tank requires certain safety and fireproofing precautions, all of
which combine to make the initial setup cost fairly high.
2. Money is tied up in the inventory stored.
3. The use of fuel oil may require a chimney.
4. If burned in an out-of-tuned unit, fuel oil will give off dirty emissions that will soil the interior of a home.
5. Fuel oil is not a renewable resource.
Gas
Gas comes in two forms: natural and liquid. Natural gas is not available in certain areas. Liquid or bottled gas can be purchased almost
anywhere.
HEATING AND COOLING
Advantages
1. Gas is a clean fuel.
2. Natural gas requires no on-site storage.
3. The liquid type can be maintained on the property.
Disadvantages
1. The natural gas supply and rate depend on the local utility company.
2. A liquid gas supply requires a storage tank.
3. Liquid gas ties up money in inventory.
4. The use of gas may require a chimney.
5. Gas is not a renewable resource.
Coal
Coal is an old-fashioned fuel that, while remaining a popular fuel
supply for the generation of electricity, is rarely used any more to heat
individual homes. It’s not readily available in all areas.
Advantages
1. Its supply can be maintained on the property.
Disadvantages
1. If you’ve ever read Victor Hugo’s Germinal, then you know what a
dirty, filthy substance coal is—even before it’s burned.
2. It’s dirty when burned, too.
3. Coal leaves large amounts of ashes after combustion occurs.
4. Naturally, the use of coal requires a chimney.
5. It’s a hot-burning fuel that possesses above-average risk of starting
house fires.
6. Its supply requires substantial storage capacity, as well as money
tied up in inventory.
7. It’s not a renewable resource.
475
476
HOW TO BUILD IT
Wood
The availability of wood depends on the local supply of hardwoods
such as oak, ash, maple, cherry, and elm.
Advantages
1. The supply can be maintained and even grown on the property.
2. If you have the equipment and time you can procure the supply
yourself.
3. It’s a renewable resource.
Disadvantages
1. Substantial labor is required to place or have the hardwood put in
storage, to move it to a stove or fireplace, and to remove the ashes
after combustion.
2. If handling and preparing the wood yourself, there’s danger
involved with using chainsaws, hand axes and mauls, and power
splitters.
3. The inventory takes up a lot of room and ties up money.
4. The use of wood requires a chimney.
5. There’s some risk of house fires.
6. Wood can bring dirt, insects, and fungi into the house.
7. The combustion of unseasoned wood can cause smoke to taint interior furnishings.
Solar
Solar energy depends on the amount of sunshine available.
Advantages
1. It’s clean.
2. There’s no charge for sunshine.
3. It should be readily available for the next few billion years.
4. It lessens the reliance on endangered and imported fuels.
HEATING AND COOLING
Disadvantages
1. Unless substantial expense is incurred, not much long-range solar
energy can be stored up. Even at best, it’s minimal when compared
with the storage capacity of other fuels.
2. How often have you known your local weather forecaster to be 100
percent accurate? There’s an inability to predict with assurance the
amount of sunlight that will occur during any one season.
3. Backup systems are needed.
4. It’s relatively expensive to plan and install a solar system.
TYPES OF HEAT PRODUCTION AND DELIVERY SYSTEMS
When it comes to selecting a heating system, there are four major
types to consider: forced-air, hot-water, heat pumps, and electrical.
Beyond those are lesser-used solar and wind-powered units.
Forced-Air Heating Units
These systems burn fuel to create a supply of warm air that’s blown
(or forced) by a fan through a duct system to various parts of the house.
During its operation, this type of furnace heats air that’s drawn from
the rooms and then sends it back through ducts and registers out again
into the rooms (Figs. 20.1 and 20.2). The enclosures that route the air
back to the furnace are known as the return ducts, and those supplying
the air are supply ducts. Before the air comes back into the furnace
from the return ducts, it goes through an air filter where most of the
fugitive airborne dirt and dust is filtered out to protect the furnace
from fouling its working parts.
Advantages
1. Forced-air systems are very versatile. Air can be heated, cooled,
humidified, dehumidified, filtered, and circulated, all through the
same distribution system.
2. A forced-air system is quick to respond manually or automatically
via the thermostat to temperature changes.
3. There’s no freezing of pipes to worry about.
477

HOW TO BUILD IT
F I G U R E 2 0 .1
Forced warm air heating system.
4. Forced-air units can operate with a pilotless ignition that uses an
electrical spark generated only at the moment the fuel flow begins.
5. A forced-air unit requires simple, low-frequency maintenance. The
filters need occasional cleaning or changing, and the electric
motors and a few moving parts may need a few drops of oil periodically. Only once a year will a typical furnace need tuning up by a
professional. In units that are heavily run, though, such tune-ups
will usually save more in energy than they cost to have done.
HEATING AND COOLING
FIGURE 20.2
Wall register with damper.
6. The installation price of forced-air heat is fairly low.
7. The distribution system requires less floor or wall space when compared with radiators for water or steam heat or electric baseboard
heat.
8. The forced-air system is adaptable to all six main types of fuel supplies.
9. Forced-air systems can be designed with more than one blower or
with special devices so the heated air can be directed to particular
locations, with each having its own thermostat. The ducts can also
have fins inside them, or movable baffles that can be used to regulate the airflow to various rooms.
Disadvantages
1. Some of the by-products of combustion—the unburned gas, oil,
soot, or other contaminants—can come out through the registers. A
poorly maintained, dirty forced-air furnace, for instance, will
inevitably transport small amounts of airborne soot through the
supply ducts and onto walls, floors, and furnishings. This process
is likely to be so gradual and insidious that the graying of white
walls, for instance, might only be revealed by washing a small area
near one of the registers or by removing an old picture from a wall.
2. Another disadvantage of forced-air heating is heat cycling. Because
the blower operates on an off-and-on basis, the room temperature
varies near the thermostat setting from an over-warm to underwarm condition and then back again. There’s a constant over-compensating going on.
3. If a blower motor is too large, or a duct system has not been properly designed, the movement of air in a room can be uncomfortable.
479
480
HOW TO BUILD IT
4. The sounds of the blower unit can be conveyed all over the house
through the ductwork.
Forced-Air Heating Considerations
1. Consider opting for a forced-air furnace with a high-efficiency (over
90-percent efficiency) condensing unit that exhausts directly outdoors via a pipe. Condensing furnaces can use true sealed combustion air drawn through a small pipe, minimizing the chances of
backdrafting, carbon monoxide poisoning, and chilly indoor drafts.
A lower-cost alternative is an energy-efficient (over 80 percent efficiency) conventional forced-air furnace that exhausts through a
chimney flue.
2. The furnace’s casing and blower compartment should be insulated.
3. The furnace operation should be quiet, with a direct-drive blower.
4. Look for an easy-to-change filter arrangement. Some units have filter doors/covers that attach magnetically, enabling the cover to be
pulled off and put back on without the use of tools. If it’s difficult
to access the filter, you’ll be less likely to change the filter as often
as should be. The filter should be replaced or cleaned regularly to
remove accumulations of dust and other particles.
5. See that there’s a drain installed for condensation discharge.
6. The air-intake pipes and furnace exhaust port should be located
above the snow line in cold-climate locations. In all areas, they
must be kept unobstructed and clean.
7. Some forced-air furnaces are two-stage models with low and high
heat output levels. They use two-stage burners, operating in lowoutput mode during moderately cold weather, and high-output
mode during cold temperatures. The furnace adjusts its own mode
of operation to best suit the circumstances. Since the furnace runs
longer in a low-heat stage (than it would in a high-output stage),
there is more continuous air circulation for household comfort and
more effective air cleaning.
Two-stage heating models offer the following advantages:
■
Increased heating comfort
■ Quieter operation
HEATING AND COOLING
■ High heating capacity to ensure comfort on coldest days
■ Longer and fewer heating cycles which provides
■ Increased air circulation
■ More consistent house temperatures
■ Improved indoor air quality
■ Reduced drafts
■ Less wear and tear on the furnace
8. Variable-speed blowers that automatically adjust to heating needs
are superior to single-speed blowers and are able to deliver better
air quality and comfort. That’s because different airflow capacities
are needed for different heat output levels. Once a furnace starts its
cycle, the blower motor on a variable-speed unit operates slowly,
then softly ramps up to full speed—preventing chilly drafts while
conserving electricity. When shutting down, the variable-speed
unit ramps down into slow speed and brings itself to a stop.
Variable speed motors offer the following advantages:
■
■
■
■
■
■
Quieter heating and cooling operation
Improved electrical efficiency all year long
Increased comfort in both heating and cooling
Economical use of continuous fan
Increased cooling efficiency
Better humidity control in cooling
Important features can be had with variable-speed blowers:
■ Furnaces with soft start and soft stop are considerably quieter
and use less energy than units without those features. They
maintain a more constant temperature, without the push and
pull of cold then warm, then cold, then warm corrections that
commonly occur with single-speed blowers.
■ They also achieve better humidity control while cooling the
household air because they run longer in the low speed.
■ They reduce furnace-caused “drafts” and minimize the shock of
blowers that abruptly come on at full speed and abruptly stop.
9. Forced-air “zoning” features a system that operates via individual
area thermostats and motorized duct dampers. They allow a home to
be segmented into zones that are individually controlled with their
481
482
HOW TO BUILD IT
own thermostats. The units typically come with a clean air filter
reminder and indoor relative humidity display, with fully modulating dampers and adjustable temperature set points. Energy is saved
by cutting back heat to zones where and when it’s not needed.
Hot-Water Heating Units
With this type of system, water is heated in a boiler by a gas, oil, or
other burner and then pumped throughout the house via a piping network equipped with radiators that ultimately distribute heat into the
rooms (Fig. 20.3). Two basic types of radiators are used. One is the familiar under-the-window style modernized with an attractive grilled cover
(Fig. 20.4), and the other is the low-profile baseboard radiator (Fig.
20.5). The disadvantages of the former are that they jut into a room and
interfere with furniture placements and drapes. The baseboard system
gives more outside wall coverage and efficiency. For these reasons it’s
generally the favored of the two. The best baseboard models are the
long, low kind about 6 to 10 inches high and up to 10 feet long, and
longer. They’re often made with copper or aluminum heating fins. The
most elite, quiet, and expensive baseboard units are the cast-iron makes.
Advantages
1. Hot-water heat is a clean, effective, and fairly quiet way to heat a
home.
2. Hot-water heating systems are adaptable to many of the more popular solar heating arrangements.
FIGURE 20.3
Hot water radiator.
HEATING AND COOLING
483
3. Hot-water heating can be zoned to
allow you to maintain different temperatures throughout the various parts of a
house.
4. Hot-water heat is a more even heat than
the heat supplied by forced-air systems.
5. Hot-water gives a moist, warm heat that
won’t dry people or furnishings out.
6. Hot-water does not create or stir up
dust, relieving allergies and easing
home cleaning requirements.
Disadvantages
1. Humidifiers, dehumidifiers, air cleaners, and air conditioners must be added
as separate systems, thus incurring
extra expense. There’s also no ductwork already in place to provide for the movement of air needed by
such add-ons.
FIGURE 20.4
Radiator.
2. Hot-water units can be difficult to keep clean. The insides of the
pipes can develop mineral deposits that reduce heating efficiencies.
3. Some hot-water systems tend to rattle and clink when the heat goes
on and off.
4. If a pipe breaks, a whole floor could get soaked.
FIGURE 20.5
Cast-iron baseboard heating unit.
484
HOW TO BUILD IT
5. The actual production of heat is not spontaneous; it takes time for
the process to start up and become operational. The complete
cycling of the water takes time initially when compared with the
immediacy of forced-air heat.
6. This type of heating system is generally more expensive than
forced-air units to purchase and have installed.
7. Having to keep furniture away from the radiators can be annoying.
8. If a home with hot-water heat will be idle during periods of freezing
temperatures, there’s the possibility of frozen and broken pipes, or
else the entire system might have to be winterized.
Hot-Water Heating Considerations
1. Look for a gas or oil “high-tech” hot-water boiler heating unit with
direct venting for greatest efficiency.
2. If your home is in an area with frequent temperature swings, a twostage low/high heat output noncondensing gas boiler will allow for
increased efficiency. When temperatures are extremely cold, the
burner operates in the high-output mode. The rest of the time the
boiler will run in low-output modes. This translates to less energy
use and increased comfort.
3. A water heater coil can be added to hot-water home heating systems to increase water-heating efficiencies.
4. Dust on radiators or baseboard units acts as insulation, and wastes
heat. These components must be accessible to be kept clean in
order to operate efficiently.
Electrical Heating Units
Another popular but less used heating system than forced-air and
hot-water is electrical. Straight electrical heating systems use electricity directly as a heat source. In essence, electricity is converted to heat
when it moves through conductors that resist the flow of current. The
conductors or heating elements become hot and give off heat. The heat
is then typically distributed via baseboard heaters that come in a wide
range of sizes (Fig. 20.6), with different output ratings so they can be
used for general heating or for supplementary purposes.
HEATING AND COOLING
485
Advantages
1. An electric heating system is one of the
simplest and least-expensive heating
systems to install. There’s no ductwork,
plumbing, or expensive furnace or
boiler needed.
2. It’s an unobtrusive and practically
silent heat.
FIGURE 20.6
3. Depending on the circumstances—
where and how it’s used—electric heat

can be very cost-efficient. Each room
can have its own control, permitting variations in the amount of
heat provided. If these controls are judiciously used, the cost of
operation can be quite low.
4. Maintenance is practically nonexistent. There’s no furnace or boiler
to service, repair, or replace.
5. Electric heating units offer the cleanest heat available.
6. Because there’s no fuel burned, there’s no need for a chimney.
7. Electric heat is adaptable to wind and other locally powered electrical sources.
Disadvantages
1. Electric heat is a very dry heat. Humidification is usually necessary
during times of low humidity.
2. Sometimes electrical heating element surfaces get hot enough to
pose a danger to young children.
3. The practical justification for electric heat can depend heavily on
what the local electric rates are in the area: how they compare with
other fuels economically.
Heat Pump Units
Earlier editions of this book contained brief discussions about heat
pumps, because years ago, the verdict on them was still out. Now, the
verdict is in, and heat pumps are certainly heating and cooling systems to be seriously considered. Just ask your local electric company.
486
HOW TO BUILD IT
Essentially, there are two basic types of heat pumps: air-to-air (or
air source), and geothermal. They collect heat from the air, ground, or
water outside the home and concentrate it for use inside. They both
also function as central air conditioners, cooling by collecting heat
inside the house and then effectively pumping it outdoors.
AIR-SOURCE HEAT PUMPS
These units (Figs. 20.7 and 20.8) employ air to store and deliver
both heat and coolness, depending on which is needed at the time.
The most common is the split-system heat pump. The main compressor, fan, and heat exchanger coil are located outdoors in a unit that
looks like a central air-conditioning compressor. Another fan and heat
exchanger coil is located inside the house within a unit that resembles
a furnace.
FIGURE 20.7
Air-source heat pump system.
HEATING AND COOLING
487
FIGURE 20.8
Air-source heat pump system.
In simple terms, an air-source heat pump heats the home during
times of cool or cold outdoor temperatures by pumping refrigerant
through a tubing or piping system that absorbs heat from the outside
air (believe it or not, there is heat available to be drawn from cold air),
carries the heat into a coil within the indoor unit, where a blower
forces the heated air through ducts to various rooms. When outdoor
temperatures are very cold, a backup electric strip-heating system
kicks in to help deliver heat throughout the home. During times of
warm or hot outdoor temperatures, the heat pump refrigerant absorbs
heat from the air inside the house, then pumps it through the outside
tubing or piping where the heat is released outside of the home.
Advantages
1. One unit can provide year-round comfort.
488
HOW TO BUILD IT
2. Units are fairly quiet.
3. No fuel delivery problems.
4. The units operate cleanly—no ashes, smoke, or soot is created. The
walls, furniture, and draperies stay clean longer.
5. Units are safe—no flames, no combustible gases, no storage of flammable fuels, no flue.
6. No worry about the future availability of heating fuels.
Disadvantages
1. Supplemental heating may be needed in areas with extreme cold
temperatures.
Air-Source Heat Pump Considerations
1. Look for two-level output capability: either two separate compressors (a large and small one) or a single two-speed compressor, both
with variable-speed blowers. With two-level output, each setting
can be tuned to run at the most efficient speed. The low-output
level will be run most of the time and will switch to the higher level
during very cold or hot weather.
2. External fittings installed in a totally sealed manner to prevent system leaks.
3. To reduce compressor operating sounds, a well-insulated compressor compartment.
4. Air filters located within the return air duct or at the indoor section
of the system.
GEOTHERMAL HEAT PUMPS
Geothermal units take advantage of the Earth’s relatively constant
ground temperature to provide very efficient heating and cooling in
any season. These are also referred to as ground-source or watersource pumps. After all, the earth is like a huge solar sponge, soaking
up energy from the sun and holding it about 6 feet below the surface,
where the soil’s temperature is between 50 and 55 degrees Fahrenheit.
Geothermal heat pumps, via heat transfer solutions traveling through
piping buried 6 to 8 feet underground, use the natural thermal mass of
HEATING AND COOLING
the Earth to withdraw heat during cold weather and to transfer heat
into during hot weather.
Geothermal heat pumps are made from two main components:
1. An indoor unit, with a compressor to circulate refrigerant, an evaporator coil to provide heat exchange between the heat transfer solution and refrigerant, a reversing valve to “switch gears” from
heating to cooling or cooling to heating, and a blower fan to send
warm or cool air through the household.
2. The underground heat-exchanger piping that’s run underground,
which allows heat transfer solution to collect heat from the ground
during winter and disburse home-captured heat to the ground during summer.
HEAT PUMP BACKUP HEAT
A geothermal heat pump does not create heat; rather, it just moves
heat from inside out, or outside in. In moderate climates, a backup
electric resistance heating system or a warm-air furnace may not be
needed. However, in extreme climates, such a backup system should
be in place.
■ With auxiliary electric resistance heat, consider getting a
“smart” controller that monitors the home’s temperature level
and brings up just enough resistance heat, in small stages, to
raise the outlet air temperature as needed.
■ When a warm-air furnace is the backup, electronic controls
choose between the operation of the heat pump or the furnace,
depending on the weather. As the outside temperature drops,
the heat pump becomes less efficient (it’s harder to draw heat
out of colder air). When the outside temperature drops to the
point where it’s no longer economical to run the heat pump, the
controls automatically switch the heat pump off and turn the
furnace on. That way, the heat pump and furnace operate at
maximum efficiency. The installation of this system costs more
than typical heating systems, but it’s very efficient and results in
very low energy usage.
There are two basic types of piping delivery/collection systems:
closed end and open end.
489
490
HOW TO BUILD IT
A closed-end system uses a solution of water/antifreeze that circulates (is pumped) through a closed ground loop of pressurized piping
that’s connected to the indoor heat pump. The Earth has the ability to
store heat energy. To use that stored energy, heat is extracted from the
earth through the liquid antifreeze solution and is pumped to the heat
pump or heat exchanger. There, the heat is used to heat the home. In
the summer, the process is reversed. Indoor heat is extracted from
within the home, then transferred back to the soil, where it dissipates.
The ground pipes are typically buried in narrow trenches 6 to 8 feet
deep. In a small yard, the pipes can be placed in vertical holes drilled
deep into the ground. To save the possibility of expensive repairs later
on, make sure the installing contractor pressure tests the piping loop
before covering up the trenches (Fig. 20.9).
The other option exists for homeowners with access to a pond or
well—an open-end system for drawing water from a well, lake, or
FIGURE 20.9
Closed-end geothermal heat pump system.
HEATING AND COOLING
pond and using it as a heat-transferring solution. Since ground water
is at a relatively constant temperature year-round, it provides a good
heat source. First, however, because of strict water usage regulations,
check the local and state laws, ordinances, codes, covenants, or
licensing requirements to see if it’s even an option. Also understand
the quality of the water that will be used. It should be tested for hardness, acidity, and iron content before the heat pump is installed.
Unacceptable water quality can cause mineral deposits to build up
inside the piping and related components, which could clog the system and make it inoperable within a relatively short time (Fig.
20.10).
The installation of geothermal units should be completed only by
experienced contractors who know how local building codes apply,
who know exactly what to do, and who supply the homeowners with
accurate, detailed records of the heat exchanger piping arrangement
F I G U R E 2 0 .1 0

491
492
HOW TO BUILD IT
and location. Such information will be necessary for any future construction or maintenance required by the system.
Advantages
1. These units are very energy efficient. Ground- and water-source
heat pumps require less supplemental energy to operate than airsource pumps need because the ground and water provide more
consistent temperatures year-round. It’s much easier during the
winter to pump heat from 55-degree soil, than it is from frigid outdoor air. In the summer, the situation is reversed, when it’s simpler to draw heat from inside the house and transport it to the
55-degree, cooler ground than to, for instance, a 92-degree, moist,
midafternoon atmosphere.
2. The closed “earth loop” piping system is inherently quieter than
noisy outdoor condenser fan units with other types of systems.
3. Added safety with geothermal units—there are no fuel tanks, no
flame, no fumes, no emissions, and no need for flues. They eliminate dangerous by-products of combustion, such as carbon
monoxide. This also results in improved household air quality.
4. A clean energy source—no ashes, soot, or fumes. Walls, furniture,
and draperies stay cleaner longer.
5. No fuel delivery problems.
6. The geothermal unit within the home is sheltered from rain, snow,
hail, and extreme temperatures and from pests such as squirrels,
rodents, and birds.
7. Additional energy savings can be realized by diverting indoor heat
to the home’s water heater for practically free hot water all summer
and for adding supplementary heat during winter, for reduced-cost
hot water then.
8. Although initial installation costs of a ground- or water-source
heat pump system is higher than that of many other systems, when
comparing all fuel types, these heat pumps are among the most
economical heating and cooling alternatives available today. Such
a system, with its low energy consumption, will be an attractive
feature for buyers if the home is ever put on the market.
HEATING AND COOLING
9. Geothermal systems are reliable and have low maintenance and a
long life span.
10. One unit can provide year-round comfort.
11. Some electric companies have offered financial assistance or
rebates to encourage the installation of heat-pump systems.
12. Some states and provinces have tax credits for installing geothermal systems.
Disadvantages
1. Supplemental heating may be required in areas of extreme cold
temperatures.
2. Initial installation costs will probably be higher than other heating/cooling systems.
Geothermal Heat Pump Considerations
1. Cabinet and compressor compartments should be insulated for
noise control.
2. Look for two-level heat pump output capability and a variablespeed blower.
3. Consider purchasing an optional water heater that can be used
for heating the house water with the heat pump. Some manufacturers offer a hot-water de-superheater that produces hot
water for household use whenever the unit runs in the cooling
mode.
4. Another option is the “space-heating-priority water-heating system.” If both the house and water heating tank need heat, the heat
pump first kicks in to take care of the home heating system, and
then to take care of the water heater.
5. Check out the warranty on the system’s underground piping. Naturally, the longer the warranty, the better. Fifty years is not unheard of.
Solar Units
A typical solar heating system that uses the sun for an energy
source includes four major components:
493
494
HOW TO BUILD IT
■
Collectors to harvest sunlight and convert radiant energy to
thermal energy
■ A storage medium that can hold enough heat to last through a
night or through periods of cloudy weather
■ A distribution system to convey the heat to points of use
■ A backup system that will take over when stored solar heat is
exhausted because the sun has not been cooperating
The collector is often a heat-absorbing metal plate with an array of
tubing that can be an integral part of the plate or merely bonded to it.
Usually this assembly is in a black frame with a layer of insulation at
the back and a glass or plastic-covered airspace on the surface that
should face the sun.
The heat transfer can be made through liquid or air that passes
through the collector, picks up heat, transports it to storage, and later
distributes it through the house.
Electric Thermal Storage Units
An electric thermal heating system can be an excellent solution for
new homes, can meet the requirements of hard-to-heat rooms, and can
easily be added at a later date for additions to home living spaces or
basements. These units employ electricity to create heat and store it in
ceramic bricks, crushed rock, or water for later use (Fig. 20.11). If the
homeowner’s electric utility company offers lower rates for consuming
electricity during off-peak hours, this type of heating system can have
considerable cost advantages.
Electric thermal heating systems come in central heating systems
and individual room systems.
Electric thermal heating units create enough heat to warm the home
immediately at night and heat their storage mediums (ceramic bricks,
crushed rock, or water) during off-peak hours when electrical demand
is least (and less costly), typically late at night. Then during peak electrical usage times, typically during the day and early evening, the heating elements are automatically turned off or down while the stored
heat is released to warm the household. It’s a great way to use electricity late at night when it’s less expensive, convert the energy into heat,
and store the heat for later use.

Advantages
1. Units operate fairly quiet.
2. Units are dependable, the heating elements have no moving parts,
which means long life.
3. Units are located indoors out of the weather.

3. No fuel delivery problems.
4. The units operate cleanly; no ashes, smoke, or soot is created. The

5. If the electric utility offers low off-peak hour rates, they can make
efficient use of electricity.
6. Units are safe—no flames, no combustible gases, no storage of flammable fuels, no flue.
7. No worry about the future availability of heating fuels.
Disadvantages
1. If individual room units are used, their placement in rooms will
take up wall space.
2. These units are designed for heating only, cooling would involve
separate equipment.
Electric Thermal Storage Units Considerations
■ An option that exists in some units, when stored radiant heat
isn’t enough to keep the room temperature at the desired thermostat setting, a quiet fan will circulate air through the core of
heated bricks or stone and warm the spaces by convection.
Radiant Floor Heating Systems
Radiant floor heating can provide a cost-effective, quiet, gentle
heat, with delivery by warm-water piping or electric wiring floor panels or mats. If you’re serious about investigating radiant floor heating
possibilities, consider meeting with contractors experienced in their
installation. There are numerous flooring situations for which this
type of heating will work, but the components must be customized
and installed to suit the type of floor planned. For instance, hydronic
(liquid) hot-water piping systems use small-diameter piping laid
within the floor in “wet” installations where the tubing is embedded
in a concrete foundation slab, or over a previously poured slab, or even
within a relatively thin thickness of concrete that’s been poured over
the top of a subfloor. Ceramic tile has typically been the floor of choice
for radiant heating, but that has been changing lately, as radiant floor
HEATING AND COOLING
heating options expand. “Dry” installations still involve tubing, but
the tubing is either suspended beneath the subfloor or is laid between
two subfloor layers, or is actually built into a sandwich-style subfloor.
This form of home heating has recently seen considerable innovation, so do a last-minute check on what’s available before making a
decision. In any case, the piping or tubing holds hot or warm water
heated by a gas, oil, or similarly-fired boiler and/or a circulation pump
(or geothermal heat pump) that circulates the water to heat the flooring. A manifold of valves controls the water distribution, and a thermostat controls the temperature—some control the temperature of
water in a boiler, while others may control the room temperature.
Another alternative for smaller homes or homes in locales with low
heating demands, is simply using a standard water heater/tank to supply the radiant floor heating. Water piping systems may cost a bit more
to install, but they’re very efficient.
Carpet, tile, vinyl, engineered wood flooring types can all be positioned over the hot-water piping that’s typically installed in a masonry
floor by a plumber or HVAC contractor. Electric panel elements provide
another option for radiant floor heating. They’re relatively inexpensive
to install, but may cost more to operate, especially if reduced off-peak
energy rates are not available from the local electric utility company.
Advantages
1. It’s quiet, even, comfortable heat.
2. It’s clean, there’s no dust generation.
3. Radiant heat does not dry out the air, there are no drafts, and less
outside-air infiltration.
4. It’s invisible, blending nicely into the home’s structure, with no
bulky ductwork or registers.
5. It’s a safe heat, with no or very few moving parts.
6. It’s energy efficient.
7. It warms from the floor up, and feels great on the feet.
Disadvantages
1. Maintenance on the piping or electrical panels could be costly.
497
498
HOW TO BUILD IT
2. A separate system is usually needed for cooled-air delivery.
3. It’s not as responsive as other forms of heat; it takes a long time for
a floor to heat up.
4. Electric heating can be relatively costly unless the electric company
offers off-peak rates when radiant floors can be heated up or
“recharged” at night.
Radiant Floor Heating Considerations
■ Recent innovations in concrete and other masonry flooring
make suitable matches with radiant floor heating. Consider that
contractors specializing in custom-concrete counter tops, table
tops, and other furniture and furnishing innovations are rapidly
becoming more available to general contractor, architects, and
the housing industry in general.
■ Laminated wood flooring is often preferred over solid wood,
which reduces the possibility of wood shrinking and cracking.
■ Early versions of radiant floor heating systems often failed due
to leaky tubes caused by corrosion from chemical reactions that
took place between the metal piping and concrete. Now plastic,
ceramic-coated, rubber, copper, and other noncorrosive tubing
is in use by most manufacturers.
COOLING SYSTEMS
Because all of the same ductwork will be shared, most forced-air
heating units are readily adaptable at a modest surcharge to include
mechanical air-conditioning. The heat pump automatically includes it
because the same equipment is used for both heating and cooling operations. If your primary heating system is not one requiring ducts, and
you still want central air-conditioning, it will have to be a separate system.
For the highest comfort, a multilevel cooling output model is best.
It matches the cooling output to changing cooling requirements of the
home. A two-speed unit is like having two systems in one: a low-speed
system for mild days and a high-speed system for hot and humid days.
Such a dual system usually operates about 80 percent of the time in
HEATING AND COOLING
low speed. Longer low-speed cycles mean better dehumidification, air
cleaning, and air circulation, for increased household comfort. Some
available cooling systems have two separate, different size compressors in the outdoor unit. When the outside air temperature is below
about 85 to 88 degrees, the small compressor runs the system. When
the outside air temperature reaches the high eighties and beyond, the
system switches to the larger compressor. On very hot days, when neither compressor alone can handle the desired cooling requirements,
both compressors kick in at once, for maximum effort. A second style
of multilevel output unit employs two-speed compressors. These multilevel output units are most effective when they use variable-speed
indoor blowers that automatically adjust to match the cooling output
required. The blower motors should have a quiet soft-start feature so
they’ll slowly ramp up to full speed, then slowly ramp down when
proper cooling levels are reached.
There are a number of important points that shouldn’t be overlooked when you’re considering the installation of air-conditioning:
1. When comparing bids from air-conditioning contractors, look at the
seasonal energy efficiency ratings (SEERs). That’s how the various
units are compared. Seventeen or 18 are excellent. Fifteen or 16 are
good, and thirteen or 14, acceptable.
2. Don’t oversize a system in hopes of getting quick cooling. If oversizing is much greater than 15 percent, a fast cool-down of the air
will occur, but without efficient moisture removal. The result will
be cold, clammy, very uncomfortable air.
3. If possible, locate outdoor compressors away from decks, patios,
bedroom windows, and dryer vents. Also avoid interior corners
that tend to accentuate the compressor noise. Try instead for a
shaded area out of the limelight. That way the noise won’t bother
anyone and no direct sunlight will unnecessarily increase the compressor coil’s workload.
4. A well-designed unit’s top will keep dirt, leaves, and debris from
clogging the insides, so hot air can be discharged upward away
from adjacent plants, patio, or grounds.
5. If you’re not starting out with air-conditioning and you plan to add
it later, arrange for a large enough heating equipment room so the
499
500
HOW TO BUILD IT
air-conditioning coil, air cleaner, and humidifier can be comfortably installed.
6. Provide a means of draining condensation water from the coil to a
nearby fixture.
7. If you plan on expanding your home at a later date, make certain
the size of your air-conditioner will accommodate it.
8. If you’re not going to have a forced-air system with ductwork, consider having the proper ductwork for air-conditioning installed
when the house is being constructed even if you’re going to wait to
have the air-conditioning put in.
9. Make sure that refrigerant used by any proposed cooling system
will be readily available in the future and is not being phased out to
comply with existing or expected environmental regulations. The
refrigerant must be both ozone- and environmentally safe.
DUCTS
Ducts can be considered the main delivery vehicles for heated and
cooled air within a home having heating and cooling systems serviced
by some type of air-moving blower unit. Two kinds of material are
used in combination to manufacture ductwork for forced-air heating
and independent air-conditioning or cooling systems: galvanized
sheet metal and fiberglass.
Galvanized sheet metal ducts are manufactured in a shop and
brought to the job site for installation. These ducts offer good support
and are put together using strong fasteners, including rivets. By themselves, however, sheet metal ducts can be annoyingly noisy. Insulating
the outside of the duct with 2-inch thick fire-resistant fiberglass duct
wrap insulation with a vapor-retarding face or liner will cut down on
noise vibration, will help control moisture condensation, and will give
thermal support by preserving the heated or cooled air temperature as
the air travels to its destination. When the sheet metal ducts are manufactured or installed, the seams, joints, and corners should be of a
good design and craftsmanship, tightly fitted to form a good seal. Sheet
metal construction offers numerous advantages: it’s durable, its
smooth surfaces offer little resistance to air flow, it can be custom-fitted to odd shapes and sizes, it isolates the outer insulation jacket from
HEATING AND COOLING
the air stream—preventing penetration of the insulation by dirt and
dust—and cleaning can be easily accomplished on the smooth surfaces with yearly dust vacuuming or in response to special situations
such as smoke or ash contamination from a fire.
Duct System Considerations
1. Insulate the outside of sheet metal ducts using 2-inch thick fireresistant fiberglass insulation with a vapor barrier.
2. To make cleaning easier, access port doors or covers can be
installed. Although few builders or home buyers think of this, duct
access ports provide the means for vacuuming collected dust from
ductwork once a year. It will keep the system, the air it supplies,
and the entire household cleaner and healthier.
3. With forced-air units total duct travel distances, as well as the number of bends and turns in the ductwork, should be minimized. The
more 90-degree bends or Ts used, the shorter the allowable or functional run can be, due to increased resistance to the airflow experienced by air swirling and losing momentum in curves and bends.
Wherever possible, 45-degree bends should be used instead of 90degree components to improve airflow efficiency. Ducts with curved
sides move air more efficiently than ducts with sharp corners.
4. In cold climates, have ducts run within heated areas of the house.
This will help maximize the amount of heat retained within the
ducts and will place more heat where it’s wanted, at a lower cost.
5. If there’s a basement, make sure a few heat outlets are placed there
to help supply warmth when needed and to cut down on dampness. They can simply be adjustable louvers installed in one of the
main heat supply ducts.
6. Warmed or cooled air that’s blown down a main or “trunk” duct
line will bounce off an end cap and disperse down the various
branch lines. If there’s a duct opening or open line at the end of the
trunk, much of the conditioned air will take the path of least resistance and continue down that path—starving the rest of the ducts.
7. There should be dampers on each branch where the branch comes
off the main trunk, so that the amount of air entering any particular
duct branch can be somewhat controlled. An unused bedroom may
501
502
HOW TO BUILD IT
thus be “sealed off” during winter and left unheated if desired. To
set dampers once the system is running, use a thermometer to
check individual room temperatures, then adjust the airflow
dampers as needed.
8. Ducts with humidifier connections will need a nearby water source
and drain.
9. Finally, do not locate air return ducts in bathrooms or kitchens;
they will pull undesired humidity back into the system from showers, baths, and cooking.
In short, carefully plan the location of furnace ducts and their outlets. Once your house is finished and occupied, you must keep furniture, rugs, and other obstructions away from the return registers,
heating and cooling vents, and related components.
REGISTERS
The purpose of heating and cooling outlets or registers is to supply
the heat or cooled air where it’s most needed, usually near the exterior
walls and windows (Fig. 20.12).
Two or more are often needed in large rooms or along extended
walls beneath long picture windows. What’s needed is a “curtain” of
warm air or cold air thrown up (or down) from the registers around the
perimeter of the house, between the occupants and the outside temperatures. The heat sources work best when they’re located along the
bottom of a wall beneath the windows. This position counteracts the
most likely places where cold might seep into the room. In warm-climate areas the registers can instead be located in the ceiling, directly
over windows on exterior walls, because cool air falls.
Here are some other considerations:
1. Make sure that no registers contribute to unwanted noise transmission between rooms. Two-sided or double-opening registers that
serve two rooms at once are fine in certain instances, but be on guard
against any doubling up that violates someone’s privacy. These double registers can be a big source of interroom noise transmission.
2. Floor-mounted supply registers are more efficient than the baseboard type. It remains a good practice, however, to use the base-
HEATING AND COOLING
board registers in rooms such as kitchens, bathrooms, and laundries to prevent water, wax, or other materials from entering the
duct system.
3. Return registers are best mounted on the walls in the interior of a
home. They should be positioned near the floor in cold-climate
areas and along the ceiling in warm-climate locations.
4. After the completion of the heating/cooling rough-in, the heating
contractor should install temporary covers over all outlets and registers, both supply and return, to prevent debris, dust, and other
materials from getting into the ductwork during the remaining construction. If temporary covers are not installed, fine dust particles
will enter the duct work and eventually coat every room in the
house when the blower turns on. Even so, it’s a good idea to request
that air ducts be cleaned at the end of construction, because even

503
504
HOW TO BUILD IT
with attempts to temporarily cover the registers, some dust, dirt
and debris may still inadvertently enter the ducts. On a related
note, make sure the heating/cooling system is disconnected and
cannot operate when the registers are covered, because restricted
air flow can damage the entire system.
5. The more areas that can be tapped for return air, the faster and more
efficient the system will be. The best systems include many more
than the minimum number of inches required for return air.
6. Registers should be scratch-resistant rustproof, with easy to operate
and set dampers.
THERMOSTATS
Thermostats shouldn’t be placed where they’ll be affected by
drafts, or in the hottest or coldest parts of a home, or in places where
they’ll interfere with furnishings and decor. Place thermostats on
inside, not outside walls.
Thermostats should be located away from heat sources such as fireplaces and registers, and from cold sources such as doors and windows, for dependable readings.
Programmable Thermostats
Programmable thermostats are electronic conveniences that can
save lots of energy. They’ll allow a heating or cooling system to be
turned down or back automatically at preset times, so heating or cooling units won’t be running full blast while occupants are sleeping or
away. Although these controls aren’t recommended with heat pumps
or radiant flooring heating systems—units meant to be run under
steady operation or systems that are difficult to shut on and off—
they’ll work wonders with many other systems.
Programmable Thermostat Considerations
1. Look for a programmable control that can store and repeat multiple
daily settings, for wake-up, daytime, evening, and sleep times.
Some “smart” units will even learn how long it takes to heat or cool
the house, so that it “knows” when to start heating or cooling in the
future. Many of those same units are also able to remind the occupants when to clean or replace the system’s air filter.
HEATING AND COOLING
2. Thermostats for heating and air conditioning should be positioned
on an inside wall where they will not be subject to draft, or heat
from televisions, lamps, and other appliances.
3. Units exist which retain programmed settings during a power outage. Better units need no batteries and operate off memory chips.
4. Some models offer a temporary program override feature for awayfrom-home vacations or holidays. You can override the program
and set the temperature down for the time you will be out of town.
5. If you go with zoned hot-water heat or have adjustable fans on your
forced-air system (dual-control fans), consider having more than
one thermostat strategically located in the house.
6. One of the newest designs is a thermidistat. It controls the furnace,
air conditioner, blower, and humidifier independently, for total
comfort.
NOISE
A noisy heating or cooling system can be annoying. There’s no justification for such noise, except that it costs the manufacturer a trifle
less and saves the builder a trifle more.
Ask to be taken to a home that already employs the heating/cooling
system that you’re considering. Listen to it start, operate, and stop. Be
sure you do all three because sometimes a burner fires with a bang, or
pops when the flame goes out. Sometimes the motor that runs a circulating pump or blower is noisy. Fan noises can be transmitted through
the ductwork (like through an old-fashioned speaking tube), and quite
often the noises created in boilers are carried throughout the house in
the metal piping.
How much attention you pay to these noises depends on your sensitivity to disturbing sounds.
SIZE AND LOCATION
You shouldn’t go with an oversized furnace or air-conditioner
unless it’s in anticipation of a room or space you plan on adding at a
later date. An oversized unit will run inefficiently in a smaller space
than it was engineered for.
505
506
HOW TO BUILD IT
Try to locate the furnace/air conditioner in as central a location as
possible to get an even distribution of heat and coolness. The air conditioner’s outside compressor, as mentioned earlier, should be installed
in an out-of-the-way place in the shade where it won’t annoy anyone.
AIR CLEANERS
Forced-air heating and air-conditioning systems are ideal for the
application of electrostatic air cleaners. They not only clean the air,
but tend to make it smell fresher too, which is a feature that’s becoming more important with today’s comprehensive sealing of houses. The
accompanying reduction of air infiltration has actually reduced the
amount of fresh air that used to move into homes through various
uninsulated surfaces and cracks in the outer shell.
Air cleaners remove up to 95 percent of airborne dust, bacteria, and
even viruses. Air cleaners have many benefits:
■ They can filter out unseen microscopic particles that float in the
air, including dust, pollen, mold, plant spores, bacteria, viruses,
dust mites, pet hair, dander, cooking smoke, and other miscellaneous particles—making the air cleaner and more comfortable
for everyone, pets included.
■ Air cleaners also keep heating and cooling equipment coils
cleaner, protecting operating efficiencies and lowering costs.
■ Cleaner air minimizes time required for cleaning dust and soil
throughout the home.
The other types of heating systems aren’t so accommodating to the
air cleaners, and separate units must be installed in individual rooms.
HUMIDIFIERS
Heat tends to dry out the air inside a house and make it uncomfortable. This is particularly true of forced-air systems. If mechanical
means for supplying moisture are not available, the humidity inside
the home can drop to the level of dryness found in a desert. This condition causes shrinking of wood and other materials, which might
open gaps in the house structure and shell and permit air infiltration.
HEATING AND COOLING
Low humidity causes a variety of problems:
■
Dry, itchy skin, dry-throat coughs, and cracked nasal membranes on people and pets
■ Sharp static electrical shocks
■ Ceiling and wall cracks that may allow hot or cold air to enter
hurting energy efficiency
■ Dehydration of some house plants
■ Excessive wear of fabrics, carpets, and other furnishings. Wood
shrinks; floors creak, banisters wobble, drawers loosen, gaps
appear in moldings
■ Household members often feel colder in homes having dry air
As with air cleaners, humidifiers can be installed directly onto a
duct system (Fig. 20.13). They can be hooked up to a constant water
supply so they’ll continually and automatically put needed moisture
into the air. For houses heated with systems other than forced-air,
humidifiers must be placed in appropriate areas throughout the home
to accomplish the same thing.
Dehumidifiers can also be needed in certain locations and times of
the year, usually in basements during hot and wet weather conditions.
Individual units run by electricity will usually do the job.
CEILING FANS
Running a ceiling fan allows you to raise an area’s air conditioner
thermostat by as much as five degrees for the same results. In winter,
reversing the fan’s rotation direction will send warm air near the ceiling to gently flow outward and down along the walls. Some ceiling
fans also function as air cleaners, with air filters hidden inside each
blade. As the fan circulates room air, the air constantly passes through
and is cleaned by the blade filters.
General Heating and Cooling Equipment Considerations
1. No matter what type of heating unit is selected, the indoor mechanical equipment location must not break up the interior floor plan. If
the main unit is placed in the basement, consider how it will impact
507
F I G U R E 2 0 .1 3
Humidifier.
the living spaces there, but remember that it will need plenty of air
circulation and must be easily accessible for maintenance and
repairs.
2. For the sake of noise reduction, the main unit should be placed
away from quiet living spaces such as bedrooms, family rooms, and
offices or libraries.
HEATING AND COOLING
3. A whole-house humidifier adds needed moisture to the air in a
home during seasonal dry spells and other times of low humidity.
Properly humidified air feels warmer than drier air of the same temperature, so you can effectively lower your indoor settings and still
enjoy comfortable conditions.
4. Wherever it’s placed, the mechanical equipment needs to be accessible for maintenance. Filters should especially be easy to get at,
with an overhead light nearby.
5. For any heating unit that’s exhausted through a chimney, make sure
the chimney has the proper liner to safely handle the exhausting.
Water vapor is a by-product of fuel combustion and can condense
on inside masonry chimney surfaces, especially those on exterior
walls. Resulting water can then be absorbed by the chimney and
transferred through walls. This can result in damp patches on interior and exterior walls, blistering paint, peeling wallpaper, stains
on the ceiling around the chimney, and white stains on the outside
surfaces of the chimney itself. During winter, chimneys may be subject to numerous freezes where the condensation freezes and
expands. This “works” on mortared joints, bricks, or blocks, and
could cause cracks and crumbling masonry which could, in turn,
lead to openings in the flue and possible incursions of dangerous
carbon monoxide into the home.
6. Rubber isolator (vibration) pads placed beneath the corners of a
forced-air furnace or heat pump blower unit will help absorb vibration and lessen operating sound levels.
7. If you choose hot-water baseboard heat but also want separate
forced-air central air-conditioning, the air-conditioning sheet metal
ductwork with outside insulation should be installed overhead
with outlets in the ceiling. The most efficient air-conditioning is
where outlets are overhead (cool air falls). The most efficient heating runs along the floor (heat rises).
8. If you’re putting in hot-water baseboard heat, and know that you’ll
want central air-conditioning at a later time, prepare for that eventuality by having the sheet metal ductwork with outside insulation
installed overhead, complete with ceiling outlets.

HOW TO BUILD IT
➤➤➤➤➤ POINTS TO PONDER
1. Forced-air heating and cooling systems are very versatile. Air
can be heated, cooled, humidified, dehumidified, filtered, and
circulated, all through the same distribution system.
2. A hot-water system is a clean, effective, and fairly quiet way to
heat a home. It can supply heat to specific areas or zones in a
house, and withhold heat from seasonally unused parts of that
same house. It also can be adapted to some household water
heaters and some solar heating arrangements.
3. An electric heating system is one of the simplest and leastexpensive heating systems to install. There’s no ductwork,
plumbing, or expensive furnace or boiler needed.
4. Although initial installation costs of a ground- or water-source
heat pump system are higher than that of many other systems,
when comparing all fuel types, these heat pumps are among the
most economical heating and cooling alternatives today—
when their low energy consumptions are considered.
5. Don’t oversize an air-conditioning system in hopes of getting
improved performance or quicker cooling. If oversizing is
much greater than 15 percent, a fast cool-down of the air will
occur, but without efficient moisture removal.
6. If possible, locate outdoor air-conditioning compressors away
from decks, patios, bedroom windows, and dryer vents.
7. In warm climates, it’s better to place heating and cooling registers in ceilings. In cold-climate locations, they should be positioned at floor levels. If you have separate heating and
air-conditioning systems (i.e., hot-water baseboard heat and
forced central air), the heating should be at floor level with the
air-conditioning in the ceiling.
8. If you’re not going to have a forced-air heating system with
ductwork, consider having the proper ductwork for air-conditioning installed when the house is being constructed, even if
you’re going to wait to have the air-conditioning put in.
9. Heating and air-conditioning ducts should be insulated on
their outside, not inside.
10. To prevent “false” readings, thermostats should be located
away from heat sources such as fireplaces and registers, and
from cold sources such as doors and windows.
CHAPTER

Insulation
T
here aren’t many people who live in a climate where they don’t
have to worry about protecting themselves from temperatures that
are periodically too hot or too cold. Since the oil embargoes and the
realization that many of the energy sources on which we depend are
not unlimited, insulation in houses has taken a position of high
priority no matter what the location.
In its most universal application, insulation belongs inside or
against any barrier located between a heated space and an unheated
space, or between a cooled space and an uncooled space. Applied to
the structure of a house, this means that insulation should be within
all exterior walls, in attics or under roofs, beneath floors exposed to
the outside as well as floors covering unheated crawl spaces or slabs,
and in extremely cold locations, on walls in a heated basement.
In short, insulation should envelop all living areas of your home,
leaving no openings except doors, windows, and necessary vents. As
discussed in the heating and plumbing chapters, the heating or cooling
ducts and hot water heater and pipes must be insulated to provide
energy efficiencies, especially when such ducts and pipes pass
through unheated or uncooled spaces.
Fortunately, sealing a home against heat conduction and air infiltration is a relatively simple process if done during construction of the
house, and it’s fairly inexpensive, considering the energy saved in the

HOW TO BUILD IT
long run. If insulation is not properly planned and must be added at a
later date after the house has been completed—now that can run into
big problems and big expenses.
Most insulation is installed after the framing is complete and the
electrical, plumbing, and heating systems have been roughed in and
inspected.
R-VALUES
Insulation quality is often expressed in “R-values.” An R-value is
merely a quantitative expression of the ability of any material to resist
the passage of heat. For example, a fiberglass batt 6 inches thick has an
R-value of approximately 19. The same material in batts 12 inches
thick will possess an R-value of about 38. The greater R-value, the
greater the material’s resistance to the passage of heat (or coolness),
and the better its insulation value.
Table 21.1 gives an insulation materials comparison. Table 21.2
lists some of the same kinds of insulations, and shows what their most
common thicknesses equal in insulating values.
Because heat rises, the potential heat loss in a house is greatest
through the roof, and least through the floors. Therefore, different recommendations exist for insulating those areas as well as the walls—
each with a different, appropriate R-factor.
Here are some conservative recommended R-values for your house:
walls—R-20; floors—R-27 (above grade), which includes overhangs,
cantilevers, and below projecting windows; and ceilings—R-40.

U-VALUES
On occasion you might find the thermal qualities of an insulation
material expressed in terms of “U.” The U-value is the reciprocal of the
R-value and can be determined by dividing the R-value into the numeral
value. For example, a fiberglass batt having an R-value of 19 has a Uvalue of 1⁄19, or .053. Basically, the lower the U-value, the greater the thermal resistance of the material, and the better its insulation quality.
TYPES OF INSULATION
While it’s true that each material used to make up your house possesses some insulating value, the effectiveness of individual types of
materials varies greatly. For example, a 1-inch-thick blanket of fiberglass insulation has the same insulation value as approximately a 31⁄2inch thick layer of pine wood planking, a 22-inch-thick wall of
common brick, a 40-inch-thick layer of solid concrete, or a 54-inchthick (41⁄2 feet!) layer of stone.
The most popular types of insulation used in modern homes are
blankets and batts of fiberglass and rock wool, rigid boards of polystyrene, fiberglass board, rigid foam boards, and various loose forms of
fiberglass and rock wool.
Fiberglass and Rock Wool Blankets and Batts
These two products make up about 90 percent of all homeowner insulation (Figs. 21.1 and 21.2). They’re made of compressed fibers that come

in a continuous roll form (blanket) or in rolls
having perforations along every few feet or
yards so you can pull off regular rectangular
pieces (batts). Both blankets and batts are
available in various thicknesses and widths,
and with or without facing material or vapor
barrier material on one side.
Fiberglass and rock wool also come in

ing if they come into direct contact with
your skin. Rock wool is the less bothersome of the two. Although loose insulation is more economical to purchase and
install, it will eventually settle and lose
some of its insulating value, and it’s difficult to move out of the way, if need be.
Fiberglass and rock wool insulation can
be used throughout the entire house, for

ity and air infiltration. They both have good
insulation values and are among the most economical types to purchase.
Rock wool insulation batts are available in semirigid models with
unique flexible edges designed to compress as the batt is placed into
walls, attics, ceiling, and floor frames. The flexible edge springs back,
expanding against whatever it is filling, to give a tight fit.
Rigid Boards
Rigid foam and Styrofoam insulation “boards” are used for basement walls, concrete slabs, cathedral ceilings, and exterior walls
before finishing (Fig. 21.3). Rigid boards are manufactured in a variety
of materials:
POLYSTYRENE RIGID BOARDS
Polystyrene is a plastic that, in rigid board form, dents easily and is
highly combustible, but is also very weather- and moisture-resistant.
INSULATION
515
It’s excellent for below-grade or exterior
wall applications. Used indoors, it’s a fire
hazard unless covered by 5⁄8-inch-thick
sheets of fire-resistant gypsum board.
FIBERGLASS BOARD

insulation family. It’s often covered by 5⁄8inch-thick fire-resistant gypsum board on interior walls and ceilings.
F I G U R E 21. 3
RIGID FOAM BOARDS
These boards have the highest insulating qualities of all rigid board
materials. They form their own vapor barriers, too. Foam board dents
easily and must be handled gently. Like many other rigid board insulations, because of its flammability, it should be covered by 5⁄8-inch
thick fire-resistant gypsum board on interior walls and ceilings.
Loose Insulation
Loose insulation can be hand-poured or blown into walls and other
voids (Fig. 21.4).
FIBERGLASS AND ROCK WOOLS
By far the most popular loose insulation. It’s efficient and inexpensive.
PLACES TO INSULATE
Even if you live in an area having a
mild climate, your home will be more
comfortable if it’s well insulated. It’s not
possible to have too much insulation in
the walls and top floor ceiling, or in floors
over carports, garages, porches, and other
areas exposed to the weather, provided the
insulation is installed correctly.
F I G U R E 21. 4

516
HOW TO BUILD IT
To prevent fire hazards, always keep insulation away from chimneys, exhaust flues, attic ventilators, and, in general, all other heatgenerating components and fixtures. Local building codes and product
manufacturers provide clearance guidelines and requirements.
There are six primary areas that should not be overlooked: basements, floors, walls, attics, ducts and plumbing, plus cracks and joints
that require caulking.
Basements
Insulation should not be installed against a wet or damp wall.
Before insulation can be applied, a dry wall in necessary; after, basement or masonry interior walls may be insulated by several methods:
■ First, by putting up furring strips followed by applying insulat-
ing blankets or batts in the usual way, with a vapor barrier facing the living area of the basement.
■
Another method is to attach rigid board insulation to wood nailing strips which are bolted to the walls. Sheets of extruded polystyrene foam are very efficient per unit of thickness. The foil-faced
vapor barrier should be placed toward the living spaces.
For either insulating method, consider using a separate vapor barrier on the back side of the insulation to prevent moisture from wall
dampness from entering or collecting against the insulation.
After basement insulation is put up, it should be covered with an
approved fire safety-rated finishing material such as 5⁄8-inch-thick fireresistant gypsum board. Find minimum guidelines for this in your
local building code.
1. In general, rigid sheets of extruded polystyrene foam are the most
efficient per unit of thickness. They’re good to add to any masonry
or concrete surface.
2. The exterior of basement foundation walls may be insulated with
extruded polystyrene rigid foam insulation. Rigid foam insulation,
with its tongue and groove design, also makes an excellent barrier
against moisture and air infiltration. It can be used below grade
because of its exceptional moisture resistance, for applications
such as concrete and masonry walls.
INSULATION
3. When foam panel board installation is complete, all joints should
be sealed with construction insulation tape.
Floors
Prudent insulation of floors can save 5 to 15 percent of your heating costs. It’s easy to insulate under floors during construction, and not
very expensive. Here’s what to consider:
1. Insulate between the top of the foundation wall and the sill plate
under the first-floor decking. This will stop air infiltration more
than it “insulates,” which is important when it comes to overall
energy efficiency and savings. Resilient polyethylene foam insulation strips are used to make an airtight seal between the masonry
foundation and the sill plate (Fig. 21.5).

2. The subfloor junction with the sole plate should be sealed. The
framing crew can place a double bead of caulk on the subfloor
before the sole plate is put in place (Fig. 21.5).
3. Underfloor insulation is important unless the first floor sits over a
heated basement. On a house with a basement, typically the furnace
is located in the basement with ducts (if a forced-air system) running
to the upper floors. Some heat will be released from the furnace and
ducts in the basement, heat that rises and helps warm the floor
above. If your house is instead built over a crawl space, consider that
a floor over an unheated crawl space can be insulated by laying blanket insulation with a vapor barrier that faces up (Fig. 21.6). The insulation bottom must be covered with approved material per your local
building code so it’s not exposed. To insulate over a concrete slab,
lay a hard, rigid board such as plywood, over the top of the slab.
4. Seal where pipes, electric wires, or telephone and television
cables penetrate the sole and top plates.
INSULATION
5. Seal around plumbing drains, and beneath bathtubs by blocking
large openings with pieces of construction sheathing and sealing
the remaining cracks with expanding foam.
6. For soundproofing, insulate the floors between a first and second
story. You can use blanket or batt fiberglass or rock wool insulation.
7. Fiberglass batts are excellent for insulating along or between the
perimeter joists. There should be a vapor barrier that faces the living side, and the insulation should be covered with a fire safetyrated material that’s specified or approved by your local building
code. One example may be 5⁄8-inch fire-resistant gypsum board.
8. All floors above cold spaces, such as vented crawl spaces, must be
insulated, and so must floors in a room that is cantilevered beyond
exterior walls below.
9. Floors of slabs built directly on the ground need insulation.
10. With crawl spaces, the insulation should be positioned with the
vapor retarder toward the warm side of the structure (in coldweather climates). The insulation can be supported with nylon
banding or metal insulation supports. The bottom of the insulation should be protected or covered by a material specified or
approved by your local building code.
Walls
Sides, tops, and bottoms of windows and doors should be insulated, with all cracks around window and door sashes and frames
filled with insulation loosely pressed into place, then sealed with
strips of vapor barrier tape, which serves as a vapor barrier. Tape
should be stapled into wood so it holds firmly.
Conduit, electrical outlets (notorious energy wasters), switch
boxes, and other fixtures and built-ins should be insulated. Fiberglass
can fill larger holes and gaps around the conduit, electrical outlets,
and switch boxes. Heat-generating electrical items must have a clearance from insulation. Reference your local building code and the fixture manufacturer’s recommendations.
1. The openings formed near corner studs, cavities, and T-junctions
created during the framing construction should all be filled with

insulation before the entire framing is completed. Otherwise it
will be very difficult, if not impossible, to get insulation into some
of those places.
2. The spaces between wall studs should be lined or filled with blankets or batts during framing. The insulation should be placed in
the stud cavities with a vapor barrier facing the living area of the
house.
3. For additional R-value, use insulated sheathing or apply rigid
board insulation to the outside of regular sheathing that might
have a low insulation value.
4. Interior walls should be insulated if you want soundproofing.
Fiberglass works well for sound control.
5. If the exterior walls of a house are covered with house wrap prior to
the application of the siding, air infiltration will be greatly reduced.
6. Drafts can be prevented around electric light switches and wall
outlets with inexpensive fire-retardant plastic foam gaskets that fit
behind the cover plates. The contractor should use only UL
approved products.
7. Insulation should be placed behind plumbing access panels and
warm-air registers.
8. Insulating the garage walls and enclosing them with drywall or
plasterboard will help retain the heat from your vehicles during
winter.
9. Knee walls are partial walls that extend from the floor to the
rafters, commonly found in one and one-half story homes and
most frequently used for bedrooms or bonus spaces. They should
be insulated.
10. Stipulate in the contract that the contractor is responsible for the
initial cleaning, both interior and exterior, of windows. Dirty glass
can block as much as 40 percent of available solar energy coming
through during the day, which could contribute to as much as 3 or
4 percent of your heating bill.
11. If your walls have metal frames, consider having continuous insulation sheathing placed over the outside of the wall framing,
between the metal framing pieces and your exterior siding.
INSULATION
12. Consider having window coverings quoted as part of the house
contract. Window insulation is available in a variety of shutters,
shades, draperies, and panels. Most curtains, blinds, shades, and
drapes provide some insulating value when closed over a window. During sunny winter days, windows receiving direct sunlight should be uncovered, since they will let in more heat than
they’ll lose.
Qualities to look for in window coverings include the following:
■
Flame-retardant materials that won’t produce dangerous fumes
if ignited
■
Moisture resistance
■
Durability
■
Quality of opening/closing mechanisms
■
Ease of operation
13. Unless exterior doors come with bottom seals, request door
sweeps be installed and positioned so the door bottom seals when
closed.
14. Openings that have been made in walls for plumbing or heating
components should be plugged to keep air and sound from traveling through. Larger openings and gaps where the walls and floors
were drilled for pipes and wiring can be packed with unfaced
fiberglass insulation. Smaller cracks and openings can be sealed
with silicone caulking.
15. Foam panels installed over the outside of exterior wall sheathing
can increase insulating values. Some tear-resistant foam panels
unfold over sheathing to form a nearly airtight seal all around the
house. This rigid foam panel board siding is made of “fanfolded” panels that minimize the number of seams and greatly
reduce the potential for air infiltration. Once the few existing
joints are covered with construction insulation tape, an efficient
seal is complete.
16. Exterior walls can receive added protection from the application
of house wrap after taping the joints or sheathing and
caulking/that helps block the chill from wind, rain, and snow.

HOW TO BUILD IT
Attics
Particularly in a single-story house,
most heat loss occurs through the attic. By
installing sufficient attic insulation you
can cut up to 30 percent of your fuel bill.
F I G U R E 21. 7
Ceiling insulation.
F I G U R E 21. 8
Cathedral ceiling insulation.
1. The most common method of insulating an attic is to staple blanket insulation between the ceiling joists with the
vapor barrier on the side closest to the
home’s living areas (Fig. 21.7). Attic
insulation should be at least 15-1⁄2 to 18
inches of standard fiberglass batts. In
cold-climate areas consider insulation
with even greater R-values.
2. If you have cathedral ceilings, the
proper way to insulate is to install batt
material between the roof rafters against
the underside of the roof sheathing or
deck before the installation of dry wall
or plasterboard (Figs. 21.8 and 21.9).
There should be an airspace of at least 3
inches between the top of the insulation
and the underside of the roof sheathing
or deck. This space is needed to ensure
proper ventilation and to provide
enough space for attic rafter and other
vents to function properly.
3. Any attic overhead pulldown doors should be hinged on one side
of the door frame and equipped with springs so that when closed,
the door can be snugly secured. The insulation that fits over the
attic side of such a door should be able to be pulled over the opening before the door is closed, unless it’s permanently attached to the
top of the attic door itself. There should also be a rubber seal
around the door frame to stop any possible air infiltration.
4. Soffit vents must not be blocked by insulation. In the attic ceiling,
baffles can be placed where the attic ceiling insulation approaches
INSULATION
F I G U R E 21. 9

soffit vents to help maintain airspace required between insulation
and roof sheathing. The baffles help prevent insulation from blocking soffet vent air flow into the attic, and help prevent insulation
from blowing into unwanted areas. (Fig. 21.10).
Attic baffles are typically extruded polystyrene, used to help
maintain constant airflow from soffit vents through the attic to the
ridge vent, preventing heat buildup. They increase attic cross ventilation; reduce cooling energy loss; minimize moisture buildup, heat
gain, and roof ice dams; and help extend the useful life of the roof.
They also keep insulation out of unwanted areas, prevent insulation
from blocking airflow from soffit vents into the attic, and keep loose
fill insulation away from recessed light fixtures or other heat-producing devices and from spilling over attic hatch door openings.
5. Attic accesses should be insulated—the back of the hatch or door
with a piece of fiberglass blanket or rigid board. The bottom of the
hatch or door should be weather-stripped to prevent heat from
transferring into the attic from below.
6. Connections between the heated space and the attic, such as
plumbing and vent stack openings, must also be sealed.

F I G U R E 2 1 .1 0
Attic rafter vent baffles.
One access cover design available is molded from lightweight
polystyrene plastic to form a hollow shell. The shell is then filled
with fiberglass insulation. The insulated cover is large enough to
cover attic stairs. Double foam weather stripping seals are attached
to the bottom edge, providing an airtight seal around the opening.
It’s hinged on its side to attic joists for easy opening.
7. Recessed lighting fixtures can be a major source of heat loss, but
you need to be careful how close insulation is placed next to a heatproducing fixture unless the fixture is marked “I.C.”—which means
“Insulated Ceiling,” which further means “designed for insulation
contact.” For all recessed lighting fixtures, verify local building
codes and light fixture manufacturers recommendations for proper
insulation clearances.
INSULATION
F I G U R E 2 1 .11
Duct insulation.
Ducts and Plumbing
By insulating heating and cooling ducts, pipes, and water heaters,
you can reduce your annual heating costs by as much as 10 percent.
1. Wherever heating ducts run through unheated parts of a house,
such as through attics, basements, or garages, they can waste as
much heat or more than they deliver. That means the occupants pay
for a lot more heat than they receive. Two-inch-thick blanket insulation is manufactured in sizes designed for wrapping around ductwork and pipes (Fig. 21.11).
2. Well-sealed vapor barriers should exist on the outside of the insulation on cooling ducts to prevent moisture buildup.
3. Water pipes need insulation, too, especially cold-water pipes
exposed to freezing temperatures in winter and hot-water pipes
installed between a water heater and fixtures. The pipe insulation
will also muffle gurgling noises and will prevent the irritating problem of condensation during warm temperatures when cold-water
pipes tend to “sweat” and drip condensate onto basement floors,
carpeting, and furnishings (Fig. 21.12).
4. For hot-water tanks, carefully read the manufacturer’s instructions
to see if additional blanket insulation is allowed. Some companies
may void the warranty if insulation is applied over the tank. If addi-
525
526
HOW TO BUILD IT
Pipe insulation.
tional insulation is permitted, instructions
must be followed to the letter, because
many critical parts cannot be covered
safely or effectively. The top or bottom of
the tank, the thermostat control, pilot
access, drain valves, pressure-relief
valves, power supply wiring, air vents,
hood drafts and other components could
become hazards if covered with additional
insulation. In all cases, make sure the tank
air vents and hood draft are clear at all
F I G U R E 2 1 .1 2
times for safe ventilation to the outdoors.
If a tankless water heater is selected, follow the manufacturer’s instructions as to
where pipe insulation can be installed.
5. Outside faucets should be able to accept a pre-made foam faucet
insulation cover for the winter, as a temporary weatherization to
prevent freezing winds from entering the house. The cover should
fit flush and securely against the exterior wall.
6. Wherever ducts penetrate a wall, ceiling, or attic floor, there must
be effective fits and tight seals. On hot water heaters, air vents or
hood draft openings must not be blocked with insulation—which
could prevent toxic fumes from being properly vented outdoors.
Likewise, neither should the top or bottom of the tank, the thermostat control, pilot light access, drain valves, pressure relief
valve, power wiring, or any other critical parts be blocked. Follow
the instructions from the water heater manufacturer for installing
insulation.
Caulking
A house is made of many different materials. With age, temperature
changes, vibration, and general wear, cracks will develop where the
different construction materials meet. Even when doors and windows
are weather-stripped, air can infiltrate through these other cracks and
joints in the floors, walls, and roof. Individually, these small cracks
might seem insignificant, but together they can cause chilly drafts and
raise heating or cooling costs.
INSULATION
They also invite insects, leaks, and rot-causing moisture. Although
you can’t expect to seal up your house completely, by caulking it thoroughly you can curb most of the drafts and heat loss. It’s a simple and
inexpensive process, yet it can cut up to 10 percent off your heating bills.
The caulking itself is an ideal solution for sealing narrow gaps and
cracks. It’s a soft, rubber-like material that will conform to any opening, will stay supple, and won’t crack or deteriorate for at least several
years, or—depending on the type of caulk used and the application—
for many years.
The following checklist presents key areas that should be caulked
in the typical house:
CAULKING CHECKLIST
✔✔✔✔✔
Around window and door frames
Anyplace a crack occurs between brick or pieces of siding
Between the foundation and the house framing walls
Around the outside of an air-conditioning unit that protrudes from a
window
Where the wood sill meets the foundation
Where exhaust hoods and fan covers pass through a wall
Where plumbing pipes enter the house (severe cold wind chill at a
tiny opening can cause a pipe to freeze)
Where telephone, cable, and electric wires enter the house
Where trim meets wood siding, brick, mortar, and other materials
Where door or window frames meet walls
Under window sills
Where floors meet walls
At corners formed by siding
Between porches and the main body of the house
Where chimney or masonry meets siding (chimney caulking is needed

✔✔✔✔✔ CAULKING CHECKLIST (Continued)
Around heating and cooling ducts and pipes running from a separate
outside central air-conditioning unit
Around pipes going to sinks and behind toilets
Around roof flashing vents, and pipes
In gutter and downspout joints
Around vents and fans
At mortar joints
Where two building/siding materials meet (i.e., brick meets stucco
or wood)
Around exterior basement doors
At window stops
Make sure weep holes at the bottom of storm windows are not
caulked or otherwise plugged. They allow moisture from condensation
to drain out or evaporate.
At seams between door jambs and door stops
Underneath metal or wooden door thresholds
Between window and door drip caps and siding
On split or broken siding
Where framing meets flooring
On gaps in the attic around pipe penetrations under the insulation, and
anywhere else cracks or gaps exist between the living area and attic.
Note: Silicone caulk stays flexible and is ideal for gaps where movement or
seasonal expansion/contraction occurs. However, most makes of silicone
caulk cannot be painted. They need to be purchased in appropriate colors.
When caulking, for gaps of 3⁄8-inch or more, the crack should be packed with
foam backer rod before the caulk is applied, so the seam won’t crack later.
VAPOR BARRIERS
In addition to insulation, a home’s living areas should also be sealed
with appropriate material (called a vapor barrier) applied along the inside
of the studs, the ceiling joists, and the floor joists—mainly to prevent the
INSULATION
movement of moisture from the living areas into the insulation. Insulation loses some of its efficiency when it becomes damp or wet, and if
moisture is not retained inside the living spaces of a home, the occupants
won’t be as comfortable and will need more heat to achieve a satisfying
inside temperature. In humid locations, however, where air-conditioning
is often running to remove moisture from the inside air, the vapor barrier
will prevent outside moisture from entering the living areas.
Vapor Barriers for Walls and Ceilings
There are three methods for applying a vapor barrier to exterior
walls or ceilings:
1. Install insulating blankets or batts having faces of vapor barrier
backing such as treated kraft paper or aluminum foil placed on the
living area side of the wall or ceiling.
2. When unfaced blanket or batt insulation is used, a separate vapor
barrier must be provided. Aluminum-backed plaster and drywall
are not effective choices because their seams don’t overlap.
3. Staple or nail polyethylene sheet material to the interior of the studs
and ceiling joists. This is probably the most effective vapor barrier.
Vapor Barriers for Floors
If blanket or batt insulation is applied between the floor joists, a
vapor barrier (per local building code specifications) should be
installed against the subfloor. The covering of the insulation on the
bottom should likewise be per code specifications.
A Safety Note
Peel back insulation and flammable vapor barriers away from the
heat-producing components or features in a house. Chimneys, flues,
stoves, electric fans, and heating sources can all be potential fire
starters. The heat-producing equipment manufacturer and your local
building code should provide guidelines for proper clearance.
SUMMER AND WINTER PROTECTION
Where possible, provide shade for sunny east, south, and west
walls and windows. Use roof overhangs, shade trees, sun screens,
529
530
HOW TO BUILD IT
shades, or interior draperies. Try to be flexible; shade makes for easier
cooling in summer, yet sunshine streaming in through a window in
winter can be a welcome sight.
Consider placing evergreen trees on the north side of the house to
help block the cold northern winter winds.
✔✔✔✔✔
SOUND CONTROL INSULATION CHECKLIST
Consider using fiberglass insulation in walls, ceilings, and floors to
control sound.
Install thick padding and carpeting to reduce impact sound. Heavily
padded carpets absorb sound far better than bare or tiled floors will.
Choose solid wood (not hollow core) interior doors with threshold
and jamb seals, where privacy is desired.
Have all windows, wiring, and piping holes caulked.
Use at least double-pane storm windows to help reduce sound transmission.
Telephone hookups, doorbells, intercoms, or audio built-ins should
be installed on interior walls only, never on common walls or corridor
walls.
Wiring, where it penetrates connecting structures, should be insulated with nonhardening caulk or dry packing.
Ceiling fixture openings need to be sealed, using before-mentioned
precautions around heat-producing components.
Electrical outlet holes should be neatly cut out to reduce sound
leaks.
Fire-retardant plastic foam gaskets may be included behind all
electrical outlets and switch covers on both sides of common walls
they’re placed in, blocking a direct route between rooms for airborne
noise.
A well-planned layout will minimize flowing water noise.
Plumbing fixtures and wall plates need caulking.
A nonhardening silicone or butyl-based caulk is also need for the
perimeter of drywall panels. Caulking around the floor, corner, and
ceiling of drywall or plasterboard must be done before the panels go
up against the wood studding. This makes sure acoustical gaps from
INSULATION
SOUND CONTROL INSULATION (Continued)
✔✔✔✔✔
warped or uneven studs are filled. The flexible caulk will help reduce
vibration.
Window treatments can help minimize sound transmission from the
outside. Heavy draperies and quilted or pleated shades will help
absorb noise better than thin metal or vinyl blinds or curtains will.
F I G U R E 2 1 .1 3
Resilient channels.
An additional sound control relies on resilient channels, U-shaped
metal strips, applied to wall studs and ceiling joists with a 1⁄2-inch by
3-inch gypsum nailing strip at the bottom. The channels help break
up sound waves and isolate noise. Fiberglass or mineral wool batts
should be stapled in the stud spaces. Since the channels are resilient,
they deaden sound transmission (Fig. 21.13).

Another sound-controlling wall features studs that are staggered
within the wall so no individual stud actually touches both inner surfaces of the wall. Insulation is snaked through the studs along the
entire length, leaving no gaps for sound to get through.

INSPECTION
All insulation is tightly installed, with no air gaps.
Vapor barriers face the interior of the home sides that are heated.
No punctures have been made in vapor barriers. Any rips or tears
have been repaired.
Ductwork is insulated.
Plumbing is insulated throughout the house.
All openings to the outside for plumbing, wiring, and gas lines are
sealed.
➤➤➤➤➤ POINTS TO PONDER
1. Insulation should envelop all living areas of your home, leaving
no openings except doors, windows, and necessary vents
(which may, in turn, be individually insulated, too).
2. Heating and cooling ducts, and water piping should be insulated to provide energy efficiencies.
3. Much of the insulation should be installed after the framing is
complete and the electrical, plumbing, and heating systems
have been roughed in and inspected.
4. Because heat rises, the potential heat loss in a house is greatest
through the roof.
5. Although interior walls and floors are not exposed to outside
temperatures, they should also be insulated to provide sound
barriers between rooms.
6. Insulation belongs between the top of the foundation wall and
the sill plate under the first-floor decking. Insulation should also
INSULATION
be stuffed into the cracks and small spaces between rough framing and the jambs, heads, and sills of windows and doors, and
used to fill spaces behind conduit, electrical outlets, switch
boxes, and other built-ins. Enough air space should be included
between insulation and any devices that produce heat or get hot.
7. Seal where pipes, electric wires, or telephone and television
cables penetrate the sole and top plates. Insulating foam is a
viable alternative to caulk when large gaps must be sealed
because foam fills cracks, holes, and other voids, assuming the
shape of the cavities. It does not shrink and sticks to most surfaces, including wood, metal, masonry, glass and most plastics.
8. Make sure that contractors don’t skimp on the quality of caulking they use. There isn’t much additional cost that separates
medium-quality caulking from top-quality caulking. If special
color caulking is used (as with stucco), see that you receive a
few tubes for future touch-ups and so you can purchase more of
the same caulk later.
9. Insulation loses effectiveness when damp or wet. Vapor barriers
must be applied between the living areas and insulation to prevent movement of moisture from the living areas into the insulation.
10. Where possible, provide shade for walls and windows with roof
overhangs, trees, blinds, shades, or interior draperies, and plant
evergreen trees and shrubs for wind blocks.

Wall Covering and Trim
T
he materials you select to cover your inside walls, plus the trim
that’s installed along corners and joints, are features that should
weigh heavily in your decorating scheme. They’re part of a home’s
inside cosmetics—what you and your visitors will see—and part of
the home’s structure.
WALL COVERINGS
There are a number of possibilities to select from when it comes to
covering or finishing off the inside walls. The most popular materials
are drywall, plaster, and paneling. If drywall or plaster is selected,
then specify if you want the finished surfaces painted or wallpapered.
Drywall Installation
Drywall consists of large (usually 4- by 8-foot) panels of prefabricated gypsum plaster sheathed on both sides with paper (Fig. 22.1).
■ Panels are measured to fit, cut to fit, and screwed (or screwed
and glued for extra strength) to the rough walls.
■ The screws must be slightly countersunk or driven so that the
heads pass slightly through the surface of the drywall.

Drywall—vertical application.
■ A smooth continuous surface is achieved between adjacent pan-
els through filling in and troweling over the joints, cracks, and
spaces with a plasterlike “joint” compound after a thin watersaturated paper tape has been applied to each crack or space.
■ Screw depressions from the countersunk screws are filled in
with the same joint compound, then troweled smooth.
■ Lightweight but sturdy metal angles are installed wherever two
pieces of drywall form right angles, to strengthen the corners.
Edges are then troweled smooth with a thin layer of joint
compound.
WALL COVERING AND TRIM
537
■ Once the joint compound dries, it’s smoothed out with fine-grit
sandpaper. A second coat of joint compound should then be
applied and also sanded smooth when dry. The second coat
should then be followed by a third and final coat.
Final finishing is accomplished with more sanding and by lastminute “point-up” work—taking care of any minor irregularities and
making edges sharper. When everything is dry and sanded smooth, the
entire surface is painted, usually white. Once painted, there should be
no evidence of panel joints or nail indentations.
At an additional cost, special finishes may be applied to drywall (and
ceilings) in “skim” coatings of topping compounds similar to plaster. A
skim coat can be left smooth, swished, dappled, ridged, or otherwise be
finished to obtain a variety of unique textures (Fig. 22.2). Some contractors will apply a coating of material, and while it’s still wet, take a large
sponge and press it against the surface, drawing out the plasterlike material in many tiny points that look like miniature stalactites. It’s a way to
have your own walls and ceilings finished in a manner that you’ll find
nowhere else.
Drywall Considerations
■ Drywall should not be applied in extreme heat or cold, to avoid
the possibility of warping or shrinkage.
■ Drywall should be carefully fit to minimize the number and
sizes of gaps.
■ Specify that contractors must use approved scaffolding for reach-
ing ceilings and high walls. Some
contractors actually use stilts to
reach indoor heights—a dangerous
practice.
■ When specifying drywall, look for 5⁄8-
inch thick fire-resistant gypsum
board. Check to make sure it meets
your local builing code.
■ When extra strength is desired, wall
adhesive can be applied to all studs
before installing drywall.
FIGURE 22.2
A textured ceiling—dappled finish.
538
HOW TO BUILD IT
■ Screws provide better holding power than nails will, with less
chance of “pop outs,” where fastener heads loosen and work their
way back through the surface of the drywall.
■ Request that all joints be taped, with three separate coats of joint
compound, each sanded smooth. Each successive coat should
leave a wider swatch or track and a smooth finish.
■ Special moisture-resistant gypsum drywall must be used along
all wall areas around shower stalls and bathtubs—and wherever
else there’s the likelihood of water or moisture present.
Advantages of Drywall
1. Drywall is relatively inexpensive to purchase and install.
2. It’s less inclined to crack than plaster.
3. It’s easier to repair than plaster.
4. Drywall can be installed quickly and doesn’t take as long to set up
as plaster does. The rest of the finishing work can proceed without
much delay.
Disadvantages
1. Drywall must be painted because its finished appearance is not uniform. All joints, screw indentations, and repairs are whiter—due to
the joint compound—than the rest of the drywall surfacing, which
✔✔✔✔✔ DRYWALL INSPECTION CHECKLIST
The following is a checklist of items that shouldn’t be overlooked with
drywall:
Cuts should be clean around register openings, wall switches, and
outlets so that covers and fixtures do not allow gaps or exposed
spaces in the drywall.
When viewed lengthwise, there should be no warped or bumpy surfaces. Nor should there be uneven surfaces to the touch.
Inquire as to how long the contractor will guarantee the drywall
against defects.

is a gray or buff color (whatever the shade of the drywall’s outer
paper layer).
2. The modular construction and the taping of drywall sections can
sometimes be discerned, especially if it’s a less-than-perfect installation. This can be worse than an occasional crack in a plaster wall.
PLASTER
Before drywall was invented, plaster was the number one way to
finish off a home’s interior walls.
Plaster Installation
Plaster is a mudlike building material that’s applied over plasterboard lathing which supplies a secure base for the plaster to adhere.
The lathing is a wallboard that usually has a gypsum core sandwiched
between layers of paper and a cardboard or foil backing that serves as
a vapor barrier. The outer layers of paper absorb water quickly so that
plaster sticks to the lath before it begins to slide. The inner layers are
treated to resist moisture.
■ Specify 5⁄8-inch-thick fire-resistant gypsum board, if it meets
your local code.
■ The lath may be solid or perforated. Perforated material
improves bonding capabilities between the plaster.
■ Gypsum lath should be applied to the studs with screws. If extra
strength is desired, it can also be glued to the studs.
■ Gaps between applied sheets should be minimized.
■ Plaster is typically applied in either a single 1⁄2-inch-thick layer
or two 3⁄8-inch-thick coats, one on top of the other.
Plaster Considerations
■ Plastering should not be done in extreme heat or cold.
■ Contractors should use approved scaffolding to reach high areas
(not stilts).
■ Screws, not nails, should be used to fasten lath to studs; for
extra strength, also apply glue to the studs.
539
540
HOW TO BUILD IT
■ Plaster can be finished in smooth or textured surfaces to com-
plement any decor. Ask the plaster contractor to show you
samples of the various options. If possible, view homes featuring different plaster options to compare looks.
■ Specify how you want the plaster finished in each room. In bath-
rooms and kitchens consider smooth surfaces for easier cleaning.
Advantages
1. Together with its lathing, a plaster wall is thicker and provides better insulation values than drywall.
2. A plaster wall is more fire-resistant than a surface finished with
drywall.
3. Plaster, with its lathing screwed to the studs, is more rigid than drywall, and less likely to bend or buckle.
4. It provides better soundproofing than drywall.
5. With plaster, a wider variety of creative artistic effects are possible.
The topping layers on drywall cannot create such startling designs
and surface modifications.
Disadvantages
1. Plaster costs more to install.
2. Plaster cracks easier than drywall does and is more difficult to repair.
✔✔✔✔✔ PLASTER INSPECTION CHECKLIST
The following is a checklist of items that shouldn’t be overlooked with
plaster:
Cuts should be clean around register openings, switches, outlets, and
fixtures, so no voids in the plaster show.
When viewed lengthwise, there should be no undulations or bumps in
the plaster’s surface. Nor should there be any uneven surfaces to the
touch.
Inspect closely for cracks.
Ask how long the contractor will guarantee the plaster work against
cracks and other defects.
WALL COVERING AND TRIM
541
3. Plaster takes longer to install. It takes time for it to dry or set up
that could otherwise be used for completing more of the wall finishing work.
PANELING
Prefabricated panels of wood and other materials are used to cover
walls because of the panels’ beauty, variety, low-maintenance qualities, and simple installation methods (Fig. 22.3). In fact, the finishing
job on drywall or plaster walls that will be covered by paneling can be
less than perfect, thus saving time.
You can find panels constructed to look and feel like a wide selection of building materials, including marble, stone, brick, and stucco.
There are even panels that simulate a wallpapered surface. These
handy prefabricated sheets are becoming increasingly popular in
kitchens, bathrooms, foyers, and even in main living areas planned
FIGURE 22.3
Paneling.
542
HOW TO BUILD IT
in today’s modern dwellings. They are still not, however, as widely
accepted as wood and wood-simulated paneling designs.
Plywood makes very good paneling for walls. It’s durable and will
add a rich look to a family room, recreation room, study, den, or dining area. Wood species such as elm, pecan, birch, and certain kinds of
walnut lend themselves nicely to use on the plywood veneers.
Paneling should be installed against walls that have already been
roughly finished in drywall or plaster, so the paneling will have sufficient backing to prevent waviness or buckling. Care must be taken to
ensure that all sections of paneling are plumb and fitted tightly
together, with adequate nailing along their edges.
Advantages
1. Paneling will not show cracks in the walls.
2. It is easy to install.
3. It adds to the insulation and sound proof values of the walls.
4. It can create many different moods for a room or area.
Disadvantages
1. Making repairs to damaged paneling can be very difficult.
2. Paneling adds to the overall expenses of wall finishing beyond the
costs of drywall or plaster.
3. It’s another step in the construction of a house that takes additional time.
TRIM
Look in any home and you’ll see wood or other trim installed wherever different construction finishing materials intersect: along joints
for instance, and corners, door frames, windows, and other built-in
house features. Trim makes an otherwise unattractive meeting place of
two planes or surfaces (such as plastered walls and wood flooring,
drywall and carpeting, wood paneling and vinyl flooring) into an
attractive border accent.
WALL COVERING AND TRIM
Trim can also have functional applications: it can tightly hold
down edges of paneling, carpeting, and linoleum, and when placed in
dining areas at chair-back height from the floor, it will prevent the
chairs from scratching the walls.
The cost of a house’s interior trimwork will vary, depending on
what you specify. Here are some general points to consider before
planning the trim for your house:
1. Even though hardwood trim is more expensive, it’s the best and
most common choice because it’s more durable than softwood trim.
2. Decide whether you want the trim to be stained, sealed, varnished,
or painted. Some contractors will charge extra, depending on how
the trim will be finished.
3. Specify where you want trim to be used. Some places in a house are
not necessarily trimmed unless you make specific arrangements for
them, such as around open doorways or around closet exteriors.
4. Be careful not to mix or have too many different molding shapes.
Match up the kind of trim material you select with the basic style of
your home.
Trim Considerations
■ If you plan to have bookshelves, get quotes along with the trim.
■ Trim needs to be protected before installation. It should be kept
out of main traffic areas to avoid dents, scratches, and waste.
■ Whenever possible, all of the trim should be purchased from the
same supplier, so pieces match. Otherwise, different shades,
grades, finishes, and dimensions may not match well together.
Top grade no. 1 trim material is well worth the relatively minor
extra cost.
■ Specify in which finish you want the trim stained.
TYPES OF TRIM AND MOLDINGS
The following types of trim are a good representation of what’s
available on the market and what each is most commonly used for

HOW TO BUILD IT
CASING TRIM
Casing trim is the molding applied
around doors and windows to cover the
junctions of the door or window frames
and finished wall. It’s available in several
styles and sizes. Doorway casing runs all
the way to the floor, past and adjacent to
baseboard trim that stops snugly against it.
BASE OR BASEBOARD TRIM
F I G U R E 2 2 .11
Trim/molding.
Base trim or molding covers the gaps
between the floor and the finished walls.
Its style is usually the same as the door
and window casing, but larger in size.
Plasterers and drywall finishers will
assume that the baseboard is at least 21⁄2
inches high and will leave unfinished that
part of the wall that is less than that distance from the floor. If you select base that’s less than 21⁄2 inches, check
with your contractor to ensure that the drywall or plaster walls will be
finished near enough to the floor so no unfinished wall will show
above the baseboard.
BASE SHOE TRIM
Base shoe trim is molding applied between the finished floor and
the baseboard. It’s very flexible and can fit tightly along both the floor
and baseboard trim, despite any irregularities of the structure that can
be present even in the best of wood construction.
BASE CAP TRIM
These narrow sections of trim may be used to handsomely “cap” the
tops of plain flat baseboard moldings. If you choose to use them, they’ll
also close any gaps that might exist between the wall and the baseboard.
CROWN-AND-BED TRIM
Crown-and-bed trim is a decorative molding used to soften sharp
lines where two planes meet. Usual applications are at corners where
walls and ceilings intersect. Such moldings are ideal for decorative
WALL COVERING AND TRIM
trimwork, around a fireplace mantel for instance, or to make picture
frames. The backs on most crown trim sections are hollow.
STOP TRIM
Stop trim is molding nailed to a door jamb to stop a closing door.
It’s also used on windows with sliding sashes.
STOOL TRIM
Stool trim is molding used at the bottom of windows to provide a
snug joint with the lowered sash.
PICTURE TRIM
Picture trim molding was so named because it was originally
designed as a perimeter trim from which pictures could be hung. It can
still be used that way, but a more modern application is to use it as a
substitute for crown trim.
SHELF EDGE OR SCREEN TRIM
This molding is designed to cover the raw edges of screening on
doors or windows, to decorate the edges of wood members such as
shelves, or to conceal exposed plywood edges.
CORNER GUARD TRIM
Corner guard trim is used to protect and finish outside corners.
DRIP CAP TRIM
Drip cap trim can be installed for use at top edges on the exterior side
of doors and windows to prevent moisture from getting inside the walls.
CHAIR RAIL TRIM
Chair rail trim is a decorative and functional molding installed
about 32 inches above the finished floor or at whatever height is best
for a particular application that would protect the walls in a room from
dining room chair or other furniture damage.
WAINSCOTING
Wainscoting can be wood planks with tongue-and-groove arrangements, paneling, or other similar materials installed on the lower
547
548
HOW TO BUILD IT
portions of interior walls, often between the baseboard and a chair rail.
The wainscoting is applied first, then the chair and baseboard trims
are fastened over the wainscoting’s bottom and top edges.
PLY CAPS
Ply caps are moldings used at the top of wainscoting to provide a
smooth finish. They’re also effective for edging plywood and for framing any panel, especially if the panel will be used as a slab for, say, a
table top.
ROUNDS
Rounds can be purchased as quarter-rounds, half-rounds, and full
rounds (Fig. 22.12). Typical applications for full rounds are as closet
poles, curtain rods, and banisters; for half-rounds, as decorative surface trim or seam covers; for quarter-rounds, as decorative trim for
inside corners and as shelf cleats.
HANDRAILS
Handrails are installed along one or both sides of a staircase
(Fig. 22.13).

Rounds.
1. When planning major-installation wall coverings such as wood
paneling, stone, and tile, give them plenty of thought because
they’re expensive and difficult to replace.
2. Even heavy-duty paneling should be
installed against walls that have
already been finished in drywall or
plaster, so the paneling will have sufficient backing to prevent waviness or
buckling.
3. Consider that paint and wallpaper are
the simplest wall surfaces with which
to make subtle and dramatic decorating changes.
4. Between drywall and plaster, remember
that drywall is less expensive, easier to

repair and work with, and is less inclined to crack than plaster. Plaster, however, lends itself to a wide variety of finished
textures when professionally applied. A plaster wall is also
more rigid, more soundproof, and more fire-resistant than
drywall.
549
550
HOW TO BUILD IT
5. Whenever you have a choice, go with stain-resistant, washable
wall surfaces. Avoid the use of flat paints for kitchens, bathrooms,
and children’s rooms. Instead, opt for semigloss or gloss coatings.
6. Even though hardwood trim is more expensive, it’s a good
choice because it’s more durable than softwood trim. If the trim
will be painted, though, softwood can be an acceptable choice
(dents and scratches can be filled with wood filler and coated
with touch-up paint).
7. Any home can benefit from the use of unique molding. Moldings can provide architectural details—at relatively small
costs—that can make the interior decor of a home far more
attractive than it would otherwise be.
8. Be careful not to mix or have too many different molding
shapes. Match up the kind of trim material you select with the
basic style of your home.
9. Consider asking the contractor for extra pieces of trim and
molding, finished exactly like those used throughout your
home, in case you eventually need to replace or add pieces for
repair/addition/maintenance reasons. Naturally, make this
request before the main trim is installed, and realize that you
may have to pay a minimal charge for the extra pieces.
10. Inexpensive vinyl trim is often an acceptable material for use
in utility rooms, sunrooms, and basement bathrooms. Extensions of a room’s carpeting can also be used as wall trim if it
suits the decorating plan.
CHAPTER

Burglar-Proofing Your Home
I
t’s true that crimes of violence, though on the rise, occur much less
frequently than crimes against property. But it’s also true that crimes
against property, such as burglary, can easily turn into crimes of
violence if an intruder is discovered and confronted.
Most thieves, burglars, and housebreakers are amateurs. Sure, on
television shows they sand their fingertips, pick combination locks,
scale buildings with grappling hooks, dress in color-coded outfits, and
perform near-perfect crimes; but in real life they’re not that classy.
Instead, most are opportunists searching for unlocked doors, open
windows, and unattended pocketbooks.
According to law enforcement experts, these amateur burglars and
housebreakers worry about three things:
■ Delay in getting into your home.
■ Being forced to work where they can be observed.
■ Having to make noise in the process.
In other words, they don’t want to cause a commotion. They don’t
want to get caught. That’s why they’ll pass by a house that has good
door and window locks and other characteristics that will delay or
announce their entry.

HOW TO BUILD IT
DOOR LOCKS
Older homes and apartments were usually built solid, with doors of
thick oak—heavy, sturdy, impossible to kick in. Unfortunately their
locks were often flimsy by comparison.
Many were mortised locks that were recessed into a hole or slot
cut from the door’s outer edge near the knob. Sometimes their locking bolt fit securely into its door frame receptacle, other times not.
If the door was “hung loose” or wobbly, often only 1⁄8 inch of bolt
kept the door locked.
Most of the remaining old-fashioned locks had keyholes, the kind
you can look through. They could be operated with skeleton keys, the
same keys that sell for under a dollar per set in any hardware store.
Not too safe.
Because skeleton locks are so easy to defeat (to open through picking or simply using other skeleton keys), many residents installed
chain units to supplement their protection. A chain lock is merely a
short chain permanently fastened to the door or door frame that, when
attached to its receiving fixture, prevents the door from being opened
more than a few inches. Again, not safe. The chains afford little safety
from a determined intruder. All the intruder has to do is kick or smash
the door with enough force to rip loose the screws holding the chain’s
receptacle to the door or frame.
Since the days of keyhole locks, safer locks have been designed and
put into use . . . some of the time. Other, unsafe locks have also come
onto the market and are being frequently used in new construction
because they’re inexpensive to produce and easy to install.
These relatively new locks are called key-in-knob locks. To open
the door from the outside you insert a key directly into a hole in the
knob, and turn. To lock it when leaving, you simply push a button on
the inside knob, or push the inside knob and turn, then slam the door
shut. The locking bolt is spring-operated.
A key-in-knob lock is the easiest modern lock to thwart. Unless
antidefeating features are built into the lock, it can be broken into in
several ways:
1. By force. Most of these locks are constructed of flimsy materials. By
placing a piece of widemouth pipe over the outside door handle,
the knob can be snapped off. And because its locking bolt is always
BURGLAR-PROOFING YOUR HOME
553
short and beveled, a crowbar or similar tool can often pry the door
open from its frame.
2. By guile. The simplest way to defeat a key-in-knob lock is to loid it.
To loid it? Yes, loiding is a new word, invented in honor of the keyin-knob lock. You probably won’t find it in your dictionary, but it
comes from the word “celluloid.” It means to open a lock by inserting a thin plastic strip (like a credit card) between the bolt and jamb
so the plastic strip releases a spring-operated catch.
If you are not yet convinced that key-in-knob locks, by themselves,
are unsafe, inquire at your local police department.
From the worst, let’s jump to the best: a single cylinder deadbolt,
operated by a key from outside and a thumb-latch inside. It throws a
1-inch rectangular (not beveled) bolt into its receptacle, and if
installed properly, cannot be pried or loided.
There is a hitch, however: if any glass is situated in or near the door
someone could break it, reach in, and turn the thumb latch from
inside. In this case, two options are available:
1. Replace the glass.
2. Replace the single cylinder lock with a
double-cylinder model—a lock operated
by key from inside and out.
The first option is the safest. That’s what
most locksmiths and law enforcement
agencies recommend. A lock that requires a
key on the inside could be hazardous in
case of a fire or other emergency. Avoid
using double-cylinder locks.
Doors already equipped with a key-inknob lock can be made safer by having
good single-cylinder deadbolts installed
above the key-in-knob lock.
In most cases, strike plates (what the
door bolt or latch locks into) should be
fastened into the door frame or jamb with
long screws, preferably 3-inch (Fig. 23.1).
F I G U R E 2 3 .1
Securing a strikeplate.
554
HOW TO BUILD IT
This setup will resist heavy blows or force that might otherwise
defeat the lock by ripping the strike plate right out of the door frame.
A lock cylinder having six pins instead of the typical five makes it
substantially harder to “pick” open. Also, unusual key designs such as
dimpled faces are harder to duplicate by illegal means.
One newly marketed door lock can be operated with either a key or
by turning the knob after a 3- or 4-digit access code is entered. This
means you could never accidentally lock yourself out, ever again.
Temporary access codes can also be set up so guests, servicepersons,
or relatives could let themselves in for some specific purpose without
knowing your master code. Various alarm settings are available to
scare off intruders who might try to turn the knob while attempting to
guess the code.
Remember, your door will be a lot more secure if it’s soundly
constructed and well-fitted to a sturdy frame. Doors having solid
wood construction at least 13⁄4 inches thick and metal doors will both
do the job.
DOOR HINGES
Door hinge pins should be located on the inside of all doors that
lead outside your home; otherwise an intruder could gain entrance by
prying up the pins with a screwdriver.
DOOR PEEPHOLES
As mentioned in the chapter on doors, peepholes should be
installed in doors to the outside that afford no other view of callers.
Plastic lenses will fog, scratch, and deteriorate in a short while. Quality
glass peepholes, with a viewing field of 180 degrees, will last a lifetime.
SLIDING DOORS
Sliding glass doors are usually situated in a family room or kitchen
dining area, facing the rear of the property. That’s great for housebreakers. Remember, they like to work in dark places where no one can
watch them.
BURGLAR-PROOFING YOUR HOME
Although most sliding doors consist of two glass panels, usually
only one of them is permanently fastened. To safeproof sliders you
must—if the window/door manufacturer has not—prevent intruders
from sliding the movable door open by force, and prevent them from
prying the movable door up and out of its track.
Probably the most common way to prevent someone from opening
the movable panel by force is to place a long wooden dowel or piece of
broom stick in the bottom track. This is not foolproof, however,
because it won’t prevent someone from simply prying the door away
from and out of its track. A special steel or wood bar that locks into the
sliding track (frequently called a “Charley Bar”) will prevent housebreakers from prying the panels off their tracks and may be purchased
commercially.
In addition, a simple cylinder lock will pin a bolt through both
doors where the doors overlap. The pin must be able to be released
quickly by anyone indoors in case of an emergency. Make sure to use
a single-cylinder lock that does not require a key to open from inside.
WINDOW LOCKS
If determined housebreakers can’t negotiate your exterior doors,
chances are they’ll turn their attention to your windows.
The windows most vulnerable in an average house are the basement windows. They should be capable of latching and locking
securely closed from the inside.
Other windows should be locked or fastened in fixed positions, either
closed all the way or opened a few inches for air in warm weather.
Double-Hung Windows
These windows are probably the most commonly used today. They
operate upward and downward, and lock with a simple metal latch.
Approach a locked double-hung window from the outside. Try sticking a knife blade up the crack and see if you can jiggle the latch with
it. An experienced housebreaker can open all but the most tightly fitting windows in this fashion. Older windows often suffer from dry rot
around their latches, and the screws that fasten the latch to the wood
can easily be pulled out.
555
556
HOW TO BUILD IT
Make certain your double-hung windows all have effective locking
mechanisms.
Casement Windows
These windows operate by means of a crank near their bottom. A
latch locks the window to a center post. Don’t include any casement
windows without effective locking latches.
Sliding Windows
These windows can be secured the same way as sliding glass
doors.
Skylights
Skylights should be locked with latches when not in use. The
openings can be protected with metal grilles latched close.
MAKING YOUR HOME SAFER
Here is a list of things you can do to help prevent burglars and other
intruders from selecting your home as a target.
1. When leaving home for several days or more, stop mail, milk, and
newspaper deliveries. Arrange for other services, when needed,
to continue as usual, such as lawn mowing and snow removal.
Consider keeping a spare car or one of your neighbor’s cars
parked conspicuously in the driveway.
2. Also, when gone, use automatic timers to turn on one or two
lights at night to fool a burglar into thinking that someone’s
home. A good choice is a bathroom light (a bathroom with an
outside window). That’s a room that could be in use at any hour
of the night.
3. While on vacation, have a relative or friend visit your home to
alter the positions of drapes and blinds and change the settings
on timers that activate lights, radio, and television so regular
patterns are not obvious.
4. Consider hiring or arranging for a house sitter during extended
absences.
BURGLAR-PROOFING YOUR HOME
5. Give your neighbors phone numbers to call in case they observe
any unusual activities that need to be reported or investigated.
Offer your assistance to them in return.
6. Never leave a key hidden outside. Instead, trust a nearby friend or
relative with one in case the police are summoned while you’re
absent. Don’t mark the key or your key ring with your name or
address. If you’re nervous about losing your keys, keep one or two
extra sets, one at home, the other with a relative or trusted neighbor.
7. Register any alarm system and advise local authorities who to
contact if your alarm goes off while you’re away.
8. Even if you don’t have burglar alarms, alarm system decals placed
on doors and windows will make burglars think twice before taking on your home. It could steer them in another direction to a
different residence.
9. Ideally, maintain lighting at all points where an intruder could
gain entry.
10. Photosensitive outside flood- and door lights that automatically
turn on and off at dusk and daylight do a good job of illuminating
the grounds.
11. If your neighborhood is dimly lit or completely dark, ask local
authorities to replace existing bulbs with others of higher wattage,
or to add new posts and lamps.
12. Keep landscaping shrubs and trees a reasonable distance from
entrances and windows, or at the very least trimmed low and
tightly cropped against the house. If too large and close they could
give burglars cover to work from.
13. Strong door locks, particularly deadbolts as mentioned earlier,
encourage burglars to move on because “forced entry” time with
less-sturdy locks is much shorter.
14. Consider installing storm windows and doors with locks.
15. Garage overhead doors that can be opened from inside an automobile by a radio remote-control unit eliminate the need for you to
get out of the car until you’re safely within the garage. They also
act as a locking device when the door is in the closed position.
557
558
HOW TO BUILD IT
16. During the day and early evening you can leave a child’s toy, a
scooter or wagon, outside, up against the house, to make it appear
that someone’s home.
17. It’s best not to display your sex and marital status on your door or
mailbox.
18. Telephone answering machines are good if programmed with a
message saying you are unable to come to the phone now, but
you’ll call back soon. Never leave a message that you’re on vacation
and will be gone until a certain date.
19. A barking dog of any size will usually scare off all but the boldest
of burglars.
20. Don’t let strangers look into your home through your windows.
Venetian and other blinds, shutters, and window treatments
prevent burglars from casing the inside of your house.
21. Peepholes on exterior doors having no windows are a must.
22. Door speakers or intercoms will allow you to speak with whoever’s at the door before opening it.
23. Request that your water, gas, and electric companies call in
advance, if possible, and arrange your appointments so you know
they’re coming ahead of time.
24. The police in your area will probably perform a free security
inspection if you schedule it with plenty of advance notice. It’s
one of the best ways to learn if you’re leaving yourself open for
trouble.
Further Safeguard Your Valuables
Record the descriptions and serial numbers of valuable items and
engrave the ones without them. Polaroids or other photos can be used
for insurance records. Include articles such as bicycles, guns, cameras,
stereos, televisions, binoculars, sewing machines, and power tools on
your protected list. Keep the records in a safe place, but not inside
your home.
Use a safe deposit box for valuables that needn’t be kept in the
house.
BURGLAR-PROOFING YOUR HOME
MONITORING SYSTEMS
Also known as burglar alarms, monitoring systems have come a
long, long way since “turn-the-Doberman-pinscher-loose-in-thelocked-house days”:
■ In-House Monitoring Box System.
Located at an out-of-theway location in the house. When activated by an intruder’s
entry, it will set off a loud horn, siren, or bell. This usually
works fine as long as neighbors are close enough to hear and
respond to the alarm if you’re away.
■
Central Monitoring System. Monitored by a central base
outside of the home, for a monthly fee. It directly and swiftly
summons police, fire, or medical emergency assistance. It dispatches personnel to respond to, inspect, and reset the alarm.
It will notify any other designated party as directed by the
homeowner and will also trigger an outside alarm.
Central monitoring systems can be linked from the home to the
central base in a variety of ways.
1. Directly Connected. By special telephone lines leased specifically
for that purpose, which can also be tied into police and fire departments. In addition to alarm signals, these lines will indicate line
faults or cuts to the receiving base.
2. Digital Dialers. These, too, send alarm signals over telephone
lines to a central monitoring office or to the police department.
The difference is that they send the signals over regular phone
lines. Regular lines won’t indicate faulty or cut wires. To remedy
this situation a local sounding device should be installed to go off
if the telephone line is disturbed or cut.
3. Automatic Dialers. These dialers deliver a prerecorded message or
a coded signal to the alarm company office, to an answering service,
to the police station, even to a neighbor, over regular phone lines.
This type of alarm should also be equipped with a local sounding
device to indicate if telephone line problems or tampering occurs.
4. Long-Range Radio Signals. These alarm signals are sent to a central
base station direct, by radio transmitter. They avoid the telephone
559
560
HOW TO BUILD IT
line problems and tampering, but require test signals to be transmitted occasionally to verify if the system is functioning.
Sensory Devices
These sensors are the eyes, ears, and other intruder-sensitive
senses of the monitoring systems.
EXTERIOR MONITORING SENSORS
■
Electric eyes/motion detectors will alert you of someone’s
approach. Can also be triggered by animals and can lead to
frequent false alarms.
■ Magnets for gates on fenced-in yards can alert you when the
gates are opened. Easily defeated, however, if an intruder climbs
over the fence.
PERIMETER SENSORS
■
Magnetic switches are attached to doors and windows and
adjacent frames. They’re wired to signal a control unit when a
magnet moves away from its switch.
■ Plunger contacts are concealed, recessed into doors or win-
dows. They operate the same way as a hidden light switch on
automobile and refrigerator doors.
■
Current-conducting foil consists of thin ribbons attached to
windows, door panels, and walls to monitor any breaking of
the surface. Unless trickily camouflaged by modernistic decor,
the foil is very noticeable.
■ Vibration or shock detectors monitor someone or something
shaking or breaking through walls, doors, or windows.
■
Special screens are available to cover windows and other
openings. They contain inconspicuous alarm wires to protect
against forced entry through the screen material. They’re
installed so an alarm will also sound if the entire screen is
removed from the opening while the system is on.
INTERIOR SENSORS
■ Photoelectric beam eyes are simple and effective. They cast an
invisible infrared light beam across hallways, rooms, stairs, and
BURGLAR-PROOFING YOUR HOME
other locations. When a beam is interrupted or “broken,” an
alarm sounds.
■ Heat detectors, although installation is simple (just plug into a
wall outlet), these units are very sensitive and can result in false
alarms more often than other types of monitor sensors, especially if pets are kept in the house. Anything that generates body
heat passing near the device is detected by the sensor.
■ Pressure mats are flat switches placed beneath mats, which, when
pressed by footsteps, alert the monitoring/alarm system.
■ Motion detectors fill the area with microwaves that are moni-
tored in a specific preset pattern. By entering the area, a person
changes the pattern and triggers an alarm. Air-conditioning and
heat vents, loose-fitting windows, phones, or anything else that
might interrupt the microwave pattern could result in faulty
alarm soundings.
■ Closed-circuit television uses a hidden camera to show outside
the door or other exterior views around the house. This setup is
of little use to a homeowner when he or she is asleep or away
from home.
Alarm System Features
1. Automatic Shutoff. Make sure the unit will automatically turn
itself off after five minutes or so. A burglar isn’t going to stick
around to wait for it to stop and if you’re not home you don’t want
the alarm to sound indefinitely. This feature is particularly beneficial if you’re not at home and the alarm is triggered accidentally
(a false alarm).
2. Area Zones. Consider a monitor box that has various area zones to
allow identification of the problem area.
3. Battery Backup. If the alarm system is not battery-powered, be
certain it at least has battery backup. Battery-operated systems
should have a way of automatically reporting impending battery
failure. A service/maintenance contract that includes automatic
battery replacement when needed is a nice safeguard.
4. Wired/Wireless. The wired systems involve hiding the wiring
installation to protect the system from being disabled and defeated.
561
562
HOW TO BUILD IT
Wireless systems are more costly and involve conspicuous sensors,
but are easily installed by anyone. It’s a good idea to inspect places
where each type has already been installed.
5. Disarming Codes. A system that permits you to readily alter the
entry disarming codes for added security.
6. Changeable Delay. Each system will give you time to enter/exit
before the alarm is set to operate. Check that the system you choose
allows for the delay time to be changed according to your needs.
7. Instant Arming. See if the system can be set for instant arming to
protect you the very moment you enter the house.
8. Panic Button. A button or device that lets you manually sound
the alarm if you know or suspect something is happening. Some
systems offer portable wireless emergency buttons that resemble
garage door openers.
9. Smoke Detector Connection. The monitor has a place for a smoke
detector to be added on line.
10. Range. Wireless systems must be powerful enough to cover the
whole area of your house.
11. Warranty. Investigate the length and coverage. Some are good for
two years, parts and labor.
12. Insurance Discount. Check if the system you’re considering will
enable you to get a discount on your homeowner’s policy.
13. Access Panel. Installed at the door or other strategic location to
allow you to arm and disarm the system. Push-button pads are
replacing lock-and-key arrangements because the push buttons
are easier to reset.
14. Malfunction Signal. Some visual or audible signal should be
provided to alert you to a problem within the system.
15. Tamper Resistance. Any components that can turn the system on
and off or render it otherwise inoperable or ineffective should be
tamper-resistant.
16. Instructions. They should be detailed and legible, so you’ll understand the system’s operations very thoroughly. Be aware of what
the system will and will not do.
BURGLAR-PROOFING YOUR HOME
17. All components should meet requirements of the Underwriter’s
Laboratories and other standards such as Factory Mutual, as well
as all applicable local standards, regulations, and codes.
ALARM INSTALLATION COMPANIES
When evaluating a burglar alarm company, consider the following
points:
1. When responding to television, radio, newspaper, or phone book
ads, don’t give out your name, address, or phone number right
away. First request and check references. Favor a well-established
company having a record of successful operations.
2. When checking company references, find out what bonding organization covers them and for how long. Ask which manufacturer they
buy from and find out if it’s reputable. Personally call on people who
have bought the installations of whichever company you are asking
about. Check with the local Better Business Bureau, Consumer
Protection Agency, Chamber of Commerce, and the police to see
if many complaints have been filed against the company in question. Find out how long the company has been in business.
3. Review the various alarm features so you know what you want and
need. Investigate their approximate cost so you will be talking
from a position of strength when the contractor enters the picture,
and so the installer cannot sell you devices you don’t require.
4. Once the installer arrives, he or she will carefully inspect all doors
and windows, furnishings, and valuables in order to recommend
what equipment you should have installed for optimum protection.
Remember, though, the more elaborate the system, the more profit
the installer makes. If the contractor realizes you know little about
alarms and what they cost, understands your financial worth and
living habits, and perceives that you are fearful of intruders, he or
she may target you for as expensive a package as possible.
5. Evaluate the service policy. What’s warranteed and how long does
the coverage last? A quality system should cover parts and labor
from both the manufacturer and the contractor for two years from
the date of installation.
563
564
HOW TO BUILD IT
6. All components and installation methods must meet the requirements of all applicable local standards, regulations, and codes.
7. Since any system of this type will require service from time to
time, you must be sure that the company you deal with can supply
prompt service. Ask what a service call will cost and get the
answer in writing.
8. Insist on receiving verbal as well as written instructions covering
all the important details of the system’s operation.
9. When considering overall costs, remember to think about the
distance to the alarm company if you’re using them as a central
monitoring station, the amount of wiring required in and to your
home, and the cost of local line rates.
10. An intruder should not be able to easily disarm the system. The
parts and wiring should be concealed as much as possible.
➤➤➤➤➤ POINTS TO PONDER
1. Remember, there’s nothing a burglar likes more than privacy.
Make a point to “case” your new home by walking the building
site before and as the dwelling is being erected. What would a
potential intruder see from the front street, from the sides, and
from the backyard? Use that information to help make your
new residence less “burglar friendly.”
2. Use lighting (especially motion-detecting and other intruderresistant) fixtures to your advantage.
3. The same goes with landscaping components. Consider that
some “small” shrubs and trees stay relatively small throughout
their lives, while others will grow to be huge unless regularly
pruned back. Don’t let your landscaping overpower the place.
Keep door and windows tastefully free from heavy foliage.
4. Insist on quality, sturdy locks for all exterior doors and windows.
5. View the home’s exterior shell as an envelope that attempts to
seal the inside living areas against opportunistic intruders from
the great outdoors. What are the weakest points? Find them in
advance, and make sure they’re reinforced by your burglarproofing plan.
BURGLAR-PROOFING YOUR HOME
6. Remember that even though “secondary” interior doors—such
as doors leading from the kitchen to a garage, breezeway, or
sunroom—may have sturdy deadbolt/locking mechanisms, the
outer doors of garages, breezeways, and sunrooms also need to
be outfitted with similar strong locks to prevent burglars from
gaining entrance to areas where they can work sight unseen.
7. Watch out for simple installation mistakes such as hinges/bolts
positioned outside instead of inside, or open access wiring to
exterior security lighting or alarms.
8. Make sure pet doors are not large enough for a slender person
to slip through. Burglars have indeed sent children into homes
in such a fashion, to pop open locked doors from within.
9. Before building, enlist someone from your police department’s
crime prevention unit, or from your insurance company’s loss
prevention department to give recommendations on how to
build security into your plan.
10. Occasionally test the effectiveness of your security. Ask a
trusted friend, relative, or neighbor to determine how he or she
would try and gain entrance (without using heroic means).

Bathrooms
B
athrooms rank right up there next to kitchens when it comes to the
most important rooms in a home. As such, the quality and number
of bathrooms in a house can greatly affect the dwelling’s resale value.
Bathroom components will also contribute considerably to the amount
of energy the family uses. Unless those components are chosen with
water and energy conservation in mind, too many energy dollars will
be going down the drain. Naturally, your family’s needs will also help
determine how many bathrooms you’ll want, and how they’ll be
appointed.
In a nutshell, bathrooms usually consist of a hand sink or lavatory,
a toilet, and a tub/shower unit (Fig. 24.1). Bathroom lavatories or sinks
are available in numerous types, styles, sizes, and colors.
TYPES OF BATHROOM SINKS
The main types of bathroom sinks or lavs include vitreous china,
porcelain/enamel over cast iron or steel, marbleized bowls or counter
units, solid composites, and concrete.
Vitreous China Sinks
These sinks are inherently acid resistant, and although they can be
stained by rust, copper corrosion, and certain other persistent staining

substances, vitreous china is considered
an excellent material, with good resistance
to chipping (Fig. 24.2). Vitreous china can
also be formed into very fancy bowls and
even into original works of art that are substantially more expensive than most other
bathroom sink units.

These are practically the least-expensive sinks you can purchase. They’re less
durable and more susceptible to chipping
and normal wear than the others mentioned here.

Marbleized Bowl/Counter Units
There are two kinds of marbleized bowl
and counter units: acrylic plastic and cast
methacrylate, both of which can contain
veining that simulates, in a highly polished surface, that of marble (Fig. 24.3).
They’re even referred to as synthetic marble. Both come in various colors and finishes, including high-gloss “onyx”
models.
These sinks are frequently integrated
into a vanity countertop, with one-piece
construction. They have a popular appearance, are easy to clean, and can be molded A marbleized sinktop.
into beautiful patterned bowls (in the form
of a seashell, for example).
The main drawback to marbleized surfaces is that the finished layers are very thin. A heavy scratch can penetrate the coating and
expose the white material underneath, which is difficult to cover up
or repair.
Solid Composites
Sinks and counters made of solid composite materials are made
with the color, often a bone white, all the way through the material.
If scratched there’s no color change and the mark can be easily
removed with steel wool or fine sandpaper. Solid composites can
also be sawn, drilled, and filed with standard carpentry tools for
custom applications. It’s one of the better materials for bathroom
(and kitchen) counters and sinks, but it’s also one of the most
expensive.
Concrete
Sinks and countertops made of concrete that’s custom-formed,
stained and sealed can be created right on site by individuals who specialize in finished concrete work. (See the section on kitchen countertops.) It’s an option that you may want to consider if you like
components that are artistically stylish and one-of-a-kind.

HOW TO BUILD IT
STYLES OF BATHROOM SINKS
More and more people are turning to designer and continental-style
lavs and lav sets. The following styles of sinks can be purchased in a
wide range of materials and prices in round, oval, or sculptured bowls.
■ Wall-hung lavs requiring no floor supports or pedestal—for
more openness and ease of cleaning.
■
Lavs supported by cabinets or pedestals.
■
Lavs supported by metal legs.
■
Lavs built into ceramic-tile surfaced counters.
■
Lavs recessed into countertops of plastic laminate. China sinks
are popular with plastic laminate countertops.
■
Single-piece sink and counter units, either molded or sculptured.
BATHROOM SINK INSTALLATION
A bathroom sink should be large enough for comfortable use, especially if it must suffice to wash your hair or bathe an infant. Try not to
select anything smaller than 20 by 24 inches. In master bedrooms, consider a double-bowl arrangement.
Every sink should have at least a narrow backsplash along the back
of the wall it’s mounted against, to protect the wall from spilled or
splashing water. A drip edge should be included at the front and side
ends of the countertop or around the tops of basin lavatories to prevent
water from overrunning the top surfaces onto the floor. Sinks should
also have an overflow prevention catch hole that drains water after it
reaches a certain upper level in the bowl.
TOILETS
Toilets or “water closets” are made in various grades, from lowcost models to luxurious units with gold-leaf seats. The best buys are
usually in the middle of any manufacturer’s range. Toilets also come
in water-saving designs that operate with less water than standard
models—an especially helpful feature if you’re in an area having
BATHROOMS

metered water, if you draw water from a
well, or if you experience periodic water
shortages.
Most toilets are made of vitreous china,
although some manufacturers carry injection-molded ABS plastic tanks as well.
The important features to look for in a
water closet are:
■ Sanitary self-cleaning action
■
Size of the free-flow water passage
■
Quietness of the flushing action
FIGURE 24.4
A siphon-jet toilet.
Types of Water Closets
There are only three basic types of toilets that you should be aware
of: siphon-jet, reverse-trap, and washdown. The first two are the only
ones you should consider for inclusion in your home.
SIPHON-JET BOWLS
The free water surface in a siphon-jet toilet bowl covers practically
the entire visible bowl area (Fig. 24.4). Water and wastes exit the
siphon-jet from the rear of the bowl.
1. A siphon-jet bowl is usually manufactured in an elongated oval
form that’s attractive and comfortable.
2. It’s the most sanitary of the three types mentioned.
3. The free-flow water passage is the largest of the three, with less
chance of becoming obstructed.
4. It’s the quietest type of the three.
5. It’s available in a one-piece wall-mounted unit that makes cleaning the bowl itself and the bathroom surfaces around it simple.
6. When made in a single piece, however, the cost is quite high
because any chip or flaw destroys the entire unit at the factory
and in your home. When the bowl and tank are separate units
the cost for the combination drops.
572
HOW TO BUILD IT
REVERSE-TRAP BOWLS
A reverse-trap bowl is a shorter type of
toilet than the siphon-jet (Fig. 24.5). Like the
siphon-jet, water and wastes exit the reversetrap from the rear of the bowl. The reversetrap toilet has a free water surface covering
roughly two-thirds of the bowl area and has
a smaller water outflow passage.
1. It’s a little less sanitary than the
siphon-jet.
FIGURE 24.5
A reverse-trap toilet.
2. It’s moderately quiet in flushing
action, and the most popular type
with builders of middle-priced
houses because it costs quite a bit
less than siphon-jet models in similar combinations of tank and bowls.
WASHDOWN BOWLS
Washdown bowls are old-fashioned type toilets that can be distinguished by their vertical front profiles. They have very small free
water areas, half that of the siphon-jet and the smallest of the three
types mentioned. Water and wastes exit the washdown models from
the front of their bowls.
1. It has a noisy flushing action.
2. It’s not effective in self-cleaning.
3. It’s the least sanitary of the three types mentioned.
BATHTUB AND SHOWER UNITS
A typical home features one bathroom having a combination bathtub and shower, and another bathroom with only a shower (Fig. 24.6).
Bathtub and Shower Sizes
Choose bathtub and shower units you’ll feel comfortable in, and
plan them in advance so the bathroom framing can be erected to size.
BATHROOMS
FIGURE 24.6
A bathtub/shower unit.
Many sizes of bathtubs are available. The usual widths are 21⁄2 to 4
feet, and lengths, 4 to 6 feet. Typical tub depth is 12 to 15 inches above
its floor surface. Numerous special models such as sunken units and
old-fashioned tubs with legs are on the market. Remember that the
deeper bathtubs will result in less water splashing.
A small shower stall is only about 30 inches square. It’s preferable to
go with one that’s between 36 and 48 inches in both width and depth.

Types of Bathtubs and Showers
FIBERGLASS TUBS AND SHOWERS
Fiberglass tubs and showers are
extremely popular units that come either
as a single molded piece complete with
walls, or with separate walls that are
assembled around the tub (Fig. 24.7). Most
new construction uses the single unit
tubs/showers having molded walls.
Advantages
1. They’re easier to clean than other
types.
2. They tend to resist mildew better
than ceramic tile surfaces.
FIGURE 24.7
A fiberglass tub and shower.
3. They solve the age-old problem of
getting a watertight joint between
the tub’s edges and the adjoining
wall surfaces.
4. These units can be purchased with their own ceilings attached.
5. Fiberglass units are warmer to the touch than the harder models,
especially during cold weather.
6. They don’t soil as quickly as conventional porcelain.
7. They can be purchased with molded-in soap holders and seats.
8. They’re very attractive and come in numerous colors.
9. They’re soft and forgiving.
Disadvantages
1. They flex under the weight of even a medium body. Sufficient
support must be placed beneath the units during installation to
prevent the fiberglass floor from “giving.”
2. When the shower water strikes the bottom of a fiberglass unit, it
tends to be somewhat noisy unless insulation is installed
between the bottom of the shower and the top of the floor, to
absorb sound.
BATHROOMS
ENAMELED CAST-IRON OR STEEL BATHTUBS
Cast-iron or steel tubs finished in regular enamel rarely come in
any other color than white. The same tubs finished with acid-resisting
enamel, however, come in white and colors. Because you can’t tell by
observation which grade of enamel is used on white tubs, the manufacturer’s warranty must be requested. Elect the models with acid
resistant enamel if a cast-iron or steel bathtub best suits your decor.
The walls above a cast-iron or steel bathtub can be finished with a
number of coverings including ceramic tile and glazelike hardboards.
Tiles come in a huge variety of colors, sizes, and patterns. The glazed
hardboards work well when installed with adhesive over a suitable
backing material such as gypsum board. Their joints, corners, and
edges are trimmed in color-matching metal moldings in various
shapes to fit the junctures. A few manufacturer’s lines of glazed hardboards have unusual patterns and themes such as of ferns, lace, multiple lines, metallics, antiqued and textured woodgrains, and other
modern surface representations.
Advantages
1. They’re exceptionally sturdy.
2. They’re a lot quieter than fiberglass.
3. The adjoining walls can be finished off in practically any way
that would best suit your decor.
Disadvantages
1. The enameled or porcelain surfaces chip very easily.
2. These tubs tend to show water stains after a period.
CERAMIC TILE BATHTUBS AND SHOWERS
Ceramic tile bathtubs and showers are just that—tubs and showers
built in place with walls and floors of ceramic tile. Often people going
with this type of bathing facilities elect to have the tub sunken
beneath the floor level. Ceramic tile applied with cement is the most
permanent installation. Tile applied with mastic glues is second best
because its performance is highly dependent on well-maintained
caulking. If water works its way through the joints, the mastic base
could deteriorate.
575
576
HOW TO BUILD IT
Advantages
1. They’re unique and colorful.
2. They offer unlimited patterns, designs, sizes, and shapes. They
can provide the ultimate customizing possibilities.
Disadvantages
1. They’re expensive.
2. The tile installation must be of superior workmanship or the
tiles will eventually loosen and the tub will leak.
3. Tiles are more difficult to clean than the other types of tub and
shower surfaces (especially the small mosaic tiles).
WHIRLPOOLS
Whirlpool bathtubs—once found only in expensive, exclusive
homes—are now available for most budgets and have become standard

fare with many contractors. Whirlpools, in addition to lending beauty
to a bathroom, are also functional. Available in a huge variety of attractive materials and colors, with many equipment options, whirlpools
provide relaxing comfort for their owners and will often improve a
home’s market value and sales potential (Fig. 24.8).
Present-day whirlpools are more energy efficient than ever—some
models giving up as little as 1 degree in temperature every 15 minutes,
with electricity to run the whirlpool circulation pump costing only a
few cents per use. During winter, the warmth that’s slowly “lost” from
the hot water can help heat the surrounding room space. The main
cost of operation is heating the water that’s used from the hot water
tank.
Some important features to select from are the tub material (cushioned models are available); the number, power, and control of water
jets; plus the shape and size (gallon capacity) of the tub. Massage jets
in the whirlpools inject an adjustable mixture of water and air to control the jet force. The size or horsepower of the pump and number of
speeds are often good indicators of the relaxing and massaging capabilities of the unit.

FIGURE 24.9

Bathtub and Shower General Considerations
A number of points should be considered while you plan your
home’s bathing facilities.
1. The plumbers should set any tub or shower unit in place before
the framing is completed (Fig. 24.9). Some of the larger molded
BATHROOMS
fiberglass units won’t fit into the house once the framing work is
finished.
2. If a tub/shower unit comes from the manufacturer covered
with protective plastic or paper, fine. The covers will protect
the unit’s finish while construction work goes on around it. If
not, it’s advisable to tape plastic around the inside of the tub,
with some thick paper on the bottom for padding, so somebody
can step inside and work around the tub without damaging the
finish.
3. A tub/shower unit should be securely fastened to the walls. This
is especially important with tubs that use ceramic tile for wall
protection. Any movement later on will cause the tub to crack
away from the tile.
4. The floor of the tub/shower should have a nonslip surface.
5. The tub/shower unit should have handles that you can live
with.
6. Remember not to place the bathtub beneath a window. This
design fault will mean providing some form of shower curtain to
cover the window, especially if the tub is equipped with a showerhead. In cold weather, a window over the tub can create
unpleasant drafts, and whenever the window must be opened,
you’ll either have to reach across the tub or step into the tub to
get enough opening leverage.
7. Specify tub/shower color.
8. Insulation should be placed in the shower walls, as well as
under the tub and in the cavities surrounding it. The insulation
will help retain the heat in the shower stall or tub. Consequently, the tub will require less hot water to stay warm.
9. All plumbing holes or penetrations through walls and floors
should be sealed with urethane foam or a similar insulation.
Remember the hole in the sub floor around the tub drain; it can
be a major source of heat loss.
10. One additional possibility, when planning tub and shower
enclosures, is the use of custom-formed concrete that’s stained
and sealed. It can be of the same type, style and finish as concrete that’s used for the room’s sink and sink countertop.

FAUCETS
The selection of faucets is a matter of personal taste. Many, many
styles are available, from high-tech to old-fashioned, constructed with
many different materials. One thing for sure, the quality faucets will
last longer and retain their appearance over the long haul.
They will also likely come with aerators. An aerator is another
device that can help save energy within your water supply. Shower
and faucet aerators are typically located in place of the standard faucet
or shower head screen. They add air to the spray to lower the flow.
High-efficiency aerators can reduce water flow from between 2 to 4
gallons per minute to less that 1 gallon per minute, which is sufficient
for most bathroom sink activities. The aerator simply reduces the
amount of water in the flow, which saves the energy that otherwise
would have been needed to heat the amount of water saved. There is a
slight reduction in flow pressure, but it will barely be noticeable There
are three basic grades of faucets: good, marginal, and cheap.
Good faucets are constructed with solid brass innards having
tough coatings of chrome, nickel, brushed or polished brass, or other
durable materials. Marginal faucets are usually made of lightweight
zinc or aluminum castings that will tarnish quickly, drip, and look
dreadful within a short time. Cheap faucets can be identified by their
crosslike handles, with four horizontal spokes coming out from their
center.
Faucets really get a good workout from the average family. Cheap
faucets just won’t do the trick. One drippy faucet may waste as much
as 50 gallons of hot water per day! Literally, money down the drain.
That’s a powerful reason for selecting a quality-made reputable brand.
In general, faucets having luxury features cost more than the
straight models. Push-pull or dual-control handles, or single-levercontrol faucets are certainly convenient, though, and are made in models of high quality.
You might realize a better price if you select all your plumbing fixtures, sink, tub, and shower, from the line of a single manufacturer.
Once the faucets are installed, check to see if the cold water is on
the right-hand side of each fixture. Believe it or not, people have been
scalded while discovering that their faucet handles had been reversed
by mistake.
BATHROOMS
✔✔✔✔✔ SHOWER/BATHTUB SAFETY VALVE CHECKLIST
Select a unit that will maintain constant water temperature.
Look for a model where you can set the sensitivity comfort zone
range between two temperatures so it’s simple to fine-tune water
temperatures.
Some units feature a preset temperature memory, which lets you set
the water temperature where you like it and the faucet “remembers”
to return to that temperature the next time it’s turned on. Certain
units allow as many as three preset bathwater temperatures to be
programmed—to accommodate different people’s preferences.
The fixtures should restrict water flow entirely until the set temperature is reached to prevent hot or cold water shocking.
Some units have safeguard rotation-limiting mechanisms or stops
that prevents a control handle from accidentally being bumped into a
fully “hot” position.
Last-temperature memory is a feature that many homeowners find
convenient.
Temperature limit stops allow you to limit how far the hot water can
be turned on. This is a feature that’s important when children or
elderly users are involved.
The best units are corrosion-, clogging-, scalding-, and erosionresistant.
Volume controls allow the water delivery rate to be adjusted as
desired.
Some are self-cleaning.
SHOWER NOZZLES
It usually takes substantially more water for a bath than for a
shower, as long as a person spends a reasonable amount of time in the
shower, and doesn’t overdo it. Even so, an efficient shower head is a
component that can help save energy and water costs. Regulating the
water going through the shower head to match the needs of the task
can greatly reduce waste and save on heated water usage. Flow restrictors with a shut-off valve and temperature controls will help with the
shower head’s efficiency.
581
582
HOW TO BUILD IT
■ Flow Restrictors: A shower-head flow restrictor can effectively
reduce the water flow from around seven gallons per minute in
the heaviest volume showers, to as little as a gallon and a half per
minute, without cutting back on pressure and without appreciably decreasing the quality and effectiveness of the shower spray.
On average, they’ll cut a family’s total energy expenditure for hot
water by over 40 percent. A shower head control should allow
the spray to be shut off altogether while a person lathers up,
shampoos, or shaves, and then to turn it on again at the same
temperature and pressure when needed to rinse.
■ Temperature Control: This is a shower handle control with
scald guard protection that maintains the temperature even if
there’s a change in water pressure. It prevents wasting water
while you try to get the desired temperature setting back.
The shower nozzle you choose should have a flexible ball joint for
directional control, plus a control to adjust the spray. Self-cleaning
showerheads make the most sense to buy. Consider a unit that’s handheld, with a pullout hose and adjustable spray and pulsating massage
sprays. Cheap nozzles offer little or no control of spray direction or
quality.
An automatic diverter control should come with a combination
tub/shower. It automatically diverts the water back to the tub faucets
after someone has taken a shower. Such a setup prevents the next person who might want to take a bath from being pelted with hot or cold
water. Omission of the diverter, an inexpensive item, can also cause
accidental scalding of children.
Shower Shock and Bathtub Shock Safety Valves
Shower and bathtub “shock” occurs when water pressure fluctuates because of changing water supply demands. For example, turn on
one faucet, and the water flow may be very strong. Turn on a second
faucet at the same time, and the pressure of the first may drop somewhat. If, while someone showers, a toilet is flushed, or a dishwasher or
clothes washer turns on, the person showering may be jolted by a
“shocking” change in water temperature (as, for instance, less cold
water makes it to the shower, and the shower water comes out hot).
With traditional faucets, a sudden change in water temperature is
BATHROOMS
what we notice most. The actual thermal shock event is a change in
water pressure. In the case of traditional bathroom faucets, if there is a
demand for cold water elsewhere in the house, the cold water pressure
at the faucet is reduced, leaving mostly hot water in the mix. An additional demand for hot water causes pressure on the hot side of the
faucet to lessen, leaving mostly cold water in the mix. Flow further
weakens with each new water outlet put into operation, causing rapid
temperature swings which could either scald or chill.
Water “shock” can be prevented by specifying bathroom plumbing
equipped with either pressure-balance or thermostatic valves. Such
valves provide a measure of safety by eliminating surges of hot or cold
water from the shower.
Pressure-balancing valves detect changes in pressure and instantly
adjust water flow to keep temperatures constant. Pressure balance
valves are designed to keep hot and cold water pressure equal at all
times. Valves use diaphragms or pistons to accomplish these feats by
adjusting the inlet ports of the faucet’s control valves.
Thermostatic valves cost more but allow you to dial in a desired
temperature, which will be maintained even as water pressure varies.
Thousands of people are injured every year from thermal shock.
The most severe scalds are caused by high-temperature water flowing
into a tub or shower. Young children and the elderly are particularly at
risk.
A second common scald injury is when someone slips in the
shower or tub and bumps the valve handle or grabs it as he or she falls,
and it gets fully turned to hot. If a person who so falls does not move
immediately, serious burns can result. The elderly often have reduced
temperature sensitivity and can unknowingly scald themselves. Thermal shock can also cause broken bones and other impact injuries that
occur as victims try to escape burning or freezing water.
Shower and tub thermal shock can be avoided through the installation of pressure-balancing or thermostatic bathtub or shower fixtures.
These fixtures will hold the bath or shower water temperature steady
to within a few degrees even though toilets are flushed or dishwashers
are started elsewhere along the home’s plumbing lines. The installation of these valves can also save on heating costs and water bills. With
fluctuating shower temperatures, time and water can be wasted just
trying to arrive at an optimum shower water temperature. Some build-

BATHROOM CABINETS
There are two types of cabinets that you
should consider for installation in your
bathrooms: medicine cabinets and lavatory cabinets.
Medicine Cabinets
Medicine cabinets are used for storing
medicines, razors, toothpaste, and other
items of personal hygiene. These cabinets
come in a variety of styles. Four of the
most popular are as follows:

■ Hinged mirror door cabinets with light-
ing fixtures positioned on both sides
(Fig. 24.12).
■ And more economical cabinets consist-
ing of single mirror doors on recessed
cabinets without lights (Fig. 24.13).
Lavatory Cabinets

ably more storage space. They also eliminate unsightly plumbing connections
below the sink, help develop the bathroom
decor, and can even be used to accommodate a built-in clothes hamper.
TOWEL WARMERS
Towel warmers (Fig. 24.15) are clever
devices that come in a number of different
types and models. All of them supply the
luxury of warm towels after a shower,
bath, or morning face wash. Some units
use electric low-wattage heating elements.
Many towel warmer bars or “tubes” are
oil-filled and permanently sealed to provide safe, even heating. Some towel warmers are simply extension units of hot-water
radiator/registers, and heat the towels

Towel warmer.
Raising the heat throughout the house
in order to warm the bathroom is a common practice, but it isn’t very energy efficient. When you want a warmer bathroom,
it’s far more effective to simply raise the
temperature there instead. The three most common ways to do that are:
1. Electric radiant heating panels installed on walls, ceilings or
floors provide heat on demand. For walls or ceilings, even a small
panel can supply the warmth needed. Because of their radiant
nature, these panels heat people and objects with a gentle warmth
without overheating and drying out the room’s air. Radiant units
are ideal for just one room. In a bathroom, people can stay warm
while in the tub or drying off even though the temperature of the
air in the bathroom is the same as the air in the rest of the house.
2. In addition to the electric radiant panels, radiant floor water
heating systems are particularly popular with people who have
allergies. That’s because radiant systems cause very little air

movement, compared with that of more traditional ducted
forced-air heating systems. There are less fugitive particles in
the air, such as airborne dust, mold spores, and animal dander.
3. A third common method of direct bathroom heating is the ceiling forced-air fan heater. Some models also provide a built-in
ventilation fan and light.
VENTILATING FANS
Energy Star-rated ventilating (or exhaust) fans, vented to the outdoors, should be installed in bathrooms to control moisture levels. The
shorter and straighter the ductwork is from the fan to the outside, the
more efficient the fan will be. If the duct must pass through an attic or
other unheated space, all ventilation ductwork should be insulated.
Excessive moisture can quickly deteriorate building materials and
furnishings, will promote the growth of mold, and can cause allergy
problems with many individuals.
Operating a vent fan is typically more efficient than simply opening a window. The fan should be designed
to quietly run for the proper amount of
time to remove moisture and odors. If it
runs too long, it draws excessive heated or
cooled air from the house. If it runs too little, then mold, fungus, and wall material
damage could occur. One of the best and
most energy efficient features to have is a
quiet automatic timer switch. (Fig. 24.16).
The fan goes on when you start the timer,
then shuts off when the desired time
period ends.
Depending on how much moisture and
humidity is present, and what the bathroom temperature is, you simply touch
the 5-, 10-, 15-, or 30-minute key to set the
timer, or bypass the pre-set keys if a different time is needed. Another reason that
F I G U R E 2 4 .1 6
having a timer is convenient is that it
gives you the ability to remove humidity

VENTILATION FAN CONSIDERATION CHECKLIST
✔✔✔✔✔
Is the unit UL approved?
Is the unit grounded with a ground-fault circuit interrupter (GFCI)?
Does the unit have a built-in damper that eliminates metallic clatter
while preventing backdrafts?
Is there a balanced high-efficiency blower?
And a permanently lubricated motor?
Resilient motor mounts for isolating vibration?
Quiet performance? Listen to a demo unit before agreeing to a particular model.
Is there a built-in nightlight control switch?
Size the vent fan properly for quiet operation. Don’t buy more fan
than you need. No matter how well the unit is designed, all other
things equal, the larger the airflow capacity, the louder the fan noise.
BATHROOMS
for up to 30 minutes after you leave the room without the worry of forgetting to turn the fan off later. For maximum efficiency, match the
bathroom ventilation or exhaust fan to the size of the room based on
cubic feet the fan moves per minute. That’s typically how the fans are
rated.
If your calculation falls between two sizes, look at the different
brands and models to find the best match. If there’s not a model with a
perfect fit, go up to the next higher fan based on cubic feet per minute.
The best exhaust fans will combine a heater, fan, room light, and nightlight into a single unit. More advanced units also have heaters that circulate warm air while removing moist air at the same time.
Automatic Ventilation Fans
Automatic ventilation fans, mounted in bathroom ceilings, will
automatically activate lamps and ventilation fans (Fig. 24.17) based on
need, to help prevent cosmetic and structural problems that can be
caused by excessive moisture buildup. Most automatic fans are operated either by:
1. Motion sensing, where sensors automatically turn on the fan,
light, or both when a person enters the room. If the user forgets
to activate or deactivate the light or fan as he or she enters or
leaves the room, the unit will do it anyway. There’s typically an
adjustable automatic shutoff time, from about 5 minutes to 60
minutes after motion stops. There should also be an adjustable
sensor where the sensing field can be modified to match specific
conditions.
BATHROOM CHECKLIST
✔✔✔✔✔
The following is a checklist of items that shouldn’t be overlooked when
you’re planning bathrooms:
A waterproof shower light.
A low-permeability vapor barrier on the inside surface of the bathroom framing to help prevent moisture from condensing in the wall
cavities.
Electrical outlets well out of reach of the shower, tub, and lavatory
water.

✔✔✔✔✔ BATHROOM CHECKLIST (Continued)
Soap holders at the lavatory, tub, and shower.
Toothbrush holders.
Shutoff valves at each fixture so water can be turned off for repairs
without turning off the main water supply to the house.
Consider having a built-in linen closet.
Consider that the plumbing plan include the installation of a PVC pan
underneath the shower as a protection against leaks.
A toilet paper holder located so it’s not subject to splashing water
from sinks, tubs, or showers, or to dripping from washcloths hanging
on a towel bar above.
A grab-bar or safety bar should be installed to serve two purposes: to
help a person using the tub to get up easily, and to help the bather
step out of the tub safely.
One 36-inch towel bar (the longest standard bar available) for each
person using the bathroom. This gives ample space for a folded bath
towel, hand towel, and washcloth. Use towel rings only for supplemental towel or washcloth storage, or for drying off wet towels.
Install the shower soap dish as far from the shower head and as high
up on the back wall as practical. Centering the dish between the ends
of the tub or shower stall results in the rapid melting of the bar soap
under prolonged exposure to the water spray.
A combination ceiling unit that includes an exhaust fan, an electric
fan-forced heater, and a light. A good ventilation fan or exhaust fan
is important for removing odors and excess humidity in the air. Such
humidity can be harmful to the walls, paint, paper, and insulation.
Consider installing several tasteful garment hooks.
Specify whether you want glass sliding doors or a shower curtain for
your shower. Doors cost considerably more, but to some people, doors
are marks of luxury. To others they represent more surfaces to clean.
The best way to select fixtures is to compare brands and see what
line of fixtures most appeals to you. Stick to one brand for each line
of fixtures. In selecting colored fixtures such as nonwhite tubs and
toilets, remember that there is a good color match between fixtures
of the same brand, but noticeable variations in the same color when
fixtures of different manufacturers are compared.
BATHROOMS
BATHROOM CHECKLIST (Continued)
✔✔✔✔✔
Anywhere sinks meet walls, or where tub or showers meet flooring,
needs to be caulked.
Moisture-resistant insulation should be installed along tub/shower
bottoms and sides to help maintain constant water temperatures.
When selecting faucets, make sure they’re compatible with the models of lavatories you’re planning.
Have ground-fault circuit interrupters (GFCIs) specified on all
receptacles.
Allow no electrical switches within 60 inches of any water, if possible.
Have a clear walkway space of at least 21 inches in front of the lavatory and toilet.
Have the toilet paper holder installed within easy reach from the toilet.
Install one or more grab-bars for safe bathtub or shower entry/exit.
Be sure all shower and bathtub faucets are protected by pressure balance temperature regulators or temperature-limiting devices.
Be sure bathroom, bathtub, and shower flooring are slip-resistant.
Install a removable handheld showerhead for flexibility when showering.
Be sure there is generous storage space, including
– Counter/shelf space around lavatory
– Grooming equipment storage
– Shampoo/soap storage in shower/tub area
– Hanging space for linens
– Towel storage/towel warmers
Be sure bathtub faucets are accessible from outside the tub.
Make child toilet seats available. They have smaller openings and
wider seat areas to make small children feel secure. They can include
molded hand grips on the sides for children to hold onto.
Install a toilet tank bowl with an insulated liner to help provide
quieter operation and prevent tank sweating that could eventually
damage the floor.
Be sure bathroom fasteners are rustproof. Even toilet seat and toilet
lid fasteners will eventually rust.
Specify the desired colors of bathroom items (tubs, showers, sinks,
toilets, and so on) so that it’s figured in the quote.

2. Humidity sensing, where monitors detect rapid increases in
humidity brought about by the bath or shower, and the fan turns
on automatically.
Inline Ventilation Fans
A remote inline vent fan is a quiet and effective bathroom exhaust
option. Sometimes called “tube” fans, these units are mounted in attics,
attached with a flexible dryer duct to a grille in the bathroom ceiling.
Since the fan motor is located away from the bathroom, the operation is
practically without sound (but will not have other built-in options such
as lights or heaters). Also, the units must be turned on and off as needed
with wall switches. By using a T duct fitting, one inline fan can vent two
or more areas simultaneously (such as two separate bathrooms).
ELECTRIC MIRRORS
This interesting product is often overlooked as a possibility, but it’s
a great bathroom feature. If you dislike waiting for a fogged-up bathroom mirror to clear after a hot shower or bath with the ventilation fan
working overtime, an electric mirror could solve the problem. An electric mirror gently warms enough to prevent condensation, thus allowing you to finish in the bathroom more quickly and to waste less
energy there.
LIGHTING FOR THE BATHROOM
All bathroom lighting, especially lighting in bathrooms without
windows, has to be well thought out. You need general plus very good
task lighting for shaving and applying makeup. And don’t forget lighting to read by in the bathtub.
Some of the most successful lighting for bathrooms is created by
indirect rather than direct light sources. Light can be bounced off a
white ceiling, concealed behind battens, and doubled off mirrors.
Where ceilings are low, choose flush recessed fittings so that you
won’t hit them while toweling off.
Lighting can also create interesting focal points that are particularly
important for internal bathrooms without windows. In fact, lighting
can even be employed to create a fake window effect.
BATHROOMS
➤➤➤➤➤ POINTS TO PONDER
1. The quality and quantity of bathrooms in a house may greatly
affect the home’s resale value.
2. Elect water-saving fixtures whenever possible. Toilets, faucets,
showerheads, and even bathtubs all can be purchased in models that take less water per use than standard units do.
3. Remember that many one-piece bathtub/shower units may not
be able to be used in bathroom additions or expansions because
they’re too large to fit through typical stairways. They need to
be installed along with the original home wall framing.
4. Make sure bathtub and shower units have nonslip surfaces.
5. Tub and shower glass doors should be made of safety glass, and
so should all mirrors used adjacent to the tub or shower.
6. Bathroom electrical outlets should all be GFCI (ground-fault
circuit interrupter) types.
7. Consider installing safety railings or support handles near tubs,
showers, and toilets.
8. Whirlpool off and on switches should be located far enough
away from the tub that no one in the tub can turn on the unit.
9. Don’t skimp on the bathroom ventilation fans; a quality fan system is required to address moisture control and healthy air
movement.
10. You should be able to unlock a bathroom from the outside in
case a child or other person locks himself or herself in.

Kitchens
I
f there’s one overall most important room in a typical house, it’s the
kitchen. Just look through the shelves of any library, bookstore, or
magazine rack. Dozens and dozens of books have been written entirely
about kitchens, and countless magazines devote their pages to the
same subject. Kitchens have spawned enormous manufacturing
invention, variety, and capacity with seemingly limitless amounts of
materials, appliances, and other items designed and marketed
specifically for home kitchen use.
It used to be that the kitchen—with its fireplace in constant use—
was the most regularly heated room of the house. It was the family
gathering place, where household members cooked, ate, talked, studied, and played cards and other games. Today, even without a wood
burning fireplace, the kitchen is still the most frequented room in the
typical home.
Ask any real estate agent which room in a home will best up the
dwelling’s market value, and he or she will invariably answer “the
kitchen.” As discussed in chapter 1, a kitchen functions as the hub in
any household. In kitchens, we prepare our meals, eat our meals,
socialize, relax, and work.
One way to look at kitchens is to think of their four major components: dining facilities, countertops, appliances, and cabinets.

HOW TO BUILD IT
DINING FACILITIES
Even if you plan to have a formal dining room, you’ll still find dining accommodations in the kitchen a convenient necessity. Consider
one or both of the following two options:
1. A table placed in the kitchen, out of the traffic flow (Fig. 25.1).
Such an arrangement, also referred to as a breakfast nook, can be
openly situated between the kitchen and another room (a family
room, for example). In some homes, the kitchen table is simply
put in a corner out of the way. Wherever it’s located, the kitchen
table and chairs should always be as close as possible to food
preparation and cleanup areas.
2. A snack bar or counter is frequently used instead of a table with
chairs (Fig. 25.2). The counter itself can be employed to separate
the kitchen from an adjacent family room or eating area, whether
F I G U R E 2 5 .1

KITCHENS
it be a nook or formal dining room. A counter is especially nice
because it encourages excellent communications and socializing; it allows whoever is working in the kitchen to carry on conversations with family members or friends while those guests
comfortably enjoy food and drink at the counter.
COUNTERTOPS
Of all parts in a kitchen, countertops get the most use. And they’re
not only used regularly, but are also subjected to the greatest abuse and
the most frequent cleaning. To be truly serviceable, a countertop surface must be able to resist moisture, heat, color fading, sharp knives
FIGURE 25.2

HOW TO BUILD IT
and blows, scratching, and staining from all sorts of nasty foods and
substances such as grape juice, beets, and Easter-egg dyes.
Countertop materials include plastic laminates, wood, ceramic tile,
solid composites, stainless steel, and concrete. And these are not your
old-fashioned versions. A lot of innovative engineering and manufacturing has gone into modern countertops. As result, they’ve got great
appearances and even greater durability. Most are simple to care for
and will last practically a lifetime.
Plastic Laminates
Plastic laminate countertops are by far more popular—due to a
combination of price, availability, and utility—than all the rest. They
come in many different styles, designs, and colors. The best ones are
factory-made in a single laminated piece consisting of a rigid base covered by a hard, heat-resistant plastic topping about 1⁄16 inch thick. This
topping is formed or molded under heat and pressure with a rolled
front edge and a vertical “backsplash” that abuts whatever wall the
countertop is mounted against.
Plastic laminate countertops come in two types of construction:
custom and postformed. The custom-made top has an advantage of
greater flexibility in shape—it’s made to fit. But it also has a joint
between the top and backsplash section that is difficult to keep clean,
plus a seam in front that’s exposed to wear and, like all laminate
seams, might come apart if the cement fails. A well-made top, though,
even with seams, will last indefinitely with proper care.
The postformed top is molded under high pressure by machinery
designed specifically for producing countertops. The result is a
smooth countertop with a seamless rounded back joint that’s easy to
clean, and a seamless smooth lip or drip edge on the front that prevents spilled liquids from running off the countertop onto the floor.
Although it’s not as nice a setup as factory-integrated laminated
models, the same kind of hard, heat-resistant types of plastic can be
adhered to flat plywood countertops, with square edges finished off in
the same plastic through the use of narrow strips that are cemented
onto the edge surfaces. The exposed edge corners are dark, showing
the thickness of the plastic laminate itself. The edges can also be covered with stainless steel or aluminum trim. In the best countertop
installations there are no joints in the worktop surface.
KITCHENS
Less-expensive polyester and vinyl plastics can be used instead of
the durable plastic previously mentioned. But both polyester and
vinyl are more susceptible to heat damage from cigarettes, hot skillets,
or other hazards.
Wood
Wood countertops are constructed of hardwood blocks or boards of
maple, beech, birch, or oak glued together in a thickness of about 11⁄8
inches or more. Wood makes an excellent, attractive surface for cutting
on and for handling hot dishes, but requires more care in cleaning and
maintenance. Plywood doesn’t make an acceptable countertop by
itself, but is commonly used as a base for other finishing materials.
Wood in the form of compressed hardboards treated with a protective
coating of tung or other oil is a low-cost alternative suitable for inexpensive kitchen designs.
Ceramic Tile
Ceramic tile makes a beautiful, easy-care countertop if well laid. It’s
colorful, distinctive, and heat- and fade-proof. It’s also hard and noisy
and can cause dish and glass breakage. Neither does it provide a good
cutting surface (a wood or plastic chopping/cutting board can take
care of that problem easy enough). Tiles can be large or small, glazed
or unglazed with nonporous vitreous bodies, and laid plain or in patterns. Stone can also be used in place of ceramic tile.
Solid Composites
Solid composites are tough, nonporous materials. They’re exceptionally durable and easy to work with. Because of their solid substance and homogeneous color, accidental burns or scratches can be
rubbed out of the countertop with common household abrasive cleaners. These countertops also come with integrated sinks. This material
is more expensive than laminated plastic, and the choice of colors is
somewhat limited, but improving as new lines are being introduced.
Concrete
Since the last edition of this book, custom and production concrete
countertops have made quite an entrance. It’s not that they haven’t
been used before. They’ve been fairly common in many other parts of
599
600
HOW TO BUILD IT
the world. It’s just that these new and improved versions have recently
been promoted by high-end users, architects, kitchen designers, writers, and builders. Now these countertops are finding their way into
typical new construction, although they’re still at upper price ranges
because of the skilled labor needed to create them—not because of the
cost of their raw materials (after all, like other concrete, countertop
concrete is made simply of water, cement, sand, stone, and color pigments). When correctly mixed, formed, cured, and finished, concrete
countertops can be artistic statements, their design limited by only the
imagination.
They may include colorful tile and stone embedded in their surface, and can offer numerous colors and texture effects. Depending on
the skill of the fabricator, features such as integral sinks, drain boards,
and decorative splash plates and edges can all be included as part of
the countertop, without seams or joints. The counters can be either
pre-cast to fit a mold that’s designed exactly to your specifications, or
cast on site. At the same time, some owners opt for matching kitchen
tables, decorative tiles, or other products that can be made with the
same color and type of concrete. Some manufacturers offer readymade finished concrete sections that can be arranged and installed as
a countertop.
Concrete, though sturdy, does have its drawbacks. It must be carefully
sealed in order to resist stains, and the seal needs to be protected with
occasional waxings. Even then, the surface may need resealing within a
year or so. Cutting on a concrete countertop will likely leave marks.
Stainless Steel
Stainless steel is another option. It’s the first choice of commercial
food service institutions such as restaurants and hotels. Stainless steel
is hard, durable, sanitary, heatproof, attractive, and expensive. It’s usually satin-finished to avoid any evidence of scratches, but constant
cleaning will eventually polish the work area anyway. On the negative
side, stainless steel is noisy and tough on dishes and glassware. And
when dirty with gritty substances, it gives some cooks the shivers
when they touch it.
Countertop Placement
Give careful thought to where you locate your counter space.
KITCHENS
1. You’ll want some near the entrance you use from the garage, to
set groceries on.
2. Some should be placed adjacent to the refrigerator where you
must put away groceries and take out food for meals.
3. If possible, try to arrange for continuous counter space from
cooking range to sink to refrigerator. The refrigerator, however,
should never be placed between the sink and the range because
it would divide the counter and impede the kitchen work flow.
4. A countertop next to the range is convenient to temporarily put
hot foods on before serving them.
5. There should be counter space on one side of the sink and dishwasher for rough cleaning and stacking of dishes and glassware
and for placing food brought back from the dining area. Another
clear countertop should be planned on the other side of the sink
and dishwasher (usually to the left) for placing the washed and
drying dishes and utensils.
APPLIANCES
The most basic kitchen planning concepts revolve around a very
simple arrangement of three common-to-all-kitchen areas: the food
preservation and storage area (refrigerator), the food preparation and
cooking areas (range, oven, and microwave), and the food mixing and
cleanup areas (sink, disposal, and dishwasher) (Fig. 25.3).
If you’re going to have a well-planned, modern kitchen, it’s wise to
outfit it with top-rated appliances. Here are four considerations you
can use to help select individual units:
1. Try to favor major appliances designed so their main components can be serviced and repaired from the front.
2. Self-diagnostic electronic controls make appliances more reliable and make it easier for service technicians or knowledgeable
appliance owners to troubleshoot problems.
3. Always compare warranty coverages.
4. Investigate the availability, reputation, and rates of the local
manufacturer’s service dealer—if there is one.

APPLIANCE EVALUATION AND OPTIONAL SERVICE CONTRACTS
Product Evaluation
It’s your first and strongest line of offense and defense against inferior appliances. Product evaluations are 95 percent of finding and purchasing the best values for your dollars. Many builders may be able to
purchase whatever appliances you select. If you happen to pick out
units that exceed the builder’s allowance, you’ll likely have to pay the
difference, but you’ll still be ahead because the builder’s cost is typically at a hefty discount.
KITCHENS
Here are some guidelines that have worked well for
consumers:
1. Select appliances and other items with established brand names
known for quality and dependability. Unfamiliar makes can be difficult and expensive to have repaired. Choose a model that best suits
your requirements. It needn’t be the least- or most-expensive model.
2. If possible, ask for a demonstration so you see the item in action
and you can learn how to operate it.
3. Find out what the availability is of competent service technicians
and spare parts. How quickly can a service call be arranged?
4. Read the warranty or guarantee made by the manufacturer. Resolve
any questions before making your selection.
Service Contracts or Extended Warranties
It’s becoming standard fare. Walk into any appliance store, electronics
shop, automobile dealership, or real estate firm. Purchase what’s
offered, and some salesperson will invariably inquire if you also want to
include, at extra cost, a service contract.
A service contract is really a form of insurance. Consider that no company in its right mind would offer an insurance policy—or a service
contract—without fully understanding the possible outcomes based on
known mathematical probabilities, and without making sure that those
probable outcomes favor the company—not the consumer. For example,
a two-year-long service contract on a new clothes dryer might cost
$120. You can be sure that the manufacturer arrived at that price based
on the knowledge that average repairs on the unit in question during
the first two years of a typical owner’s use will cost considerably less
than $120. Well, if that’s the case, then why would you ever consider or
want a service contract?
There are reasons. Perhaps you’re planning to use the appliance more
frequently than the typical user does. What if you’re the designated
uniform washer for a grade school soccer team? You know that for the
next few years—during your stint as uniform washer—you’re really
going to put 10 year’s worth of usage into your new dryer. In that case,
the service contract could likely come into play on your behalf.
603
604
HOW TO BUILD IT
Simply put, purchasing a service contract or extended warranty is a
gamble. It’s in your best interest to see that the odds are tipped at
least as far as possible toward an outcome that will be favorable to you.
If you simply feel more comfortable with and can afford service contracts and extended warranties whenever they’re offered, so be it. You’re
well covered, and you’ll be unlikely to experience any major repairs.
But, unless you plan to use those items harder than most other individuals do, you’ll probably be paying a premium for the coverage. For those
purchases that will be used for routine service, that’s why it’s important
to do your homework before you buy. Find out which makes and models
have the least number of problems, are the least expensive to run and
own, and are superior performers. If you buy the best-value items to
begin with, and if no special or extenuating circumstances exist, you
aren’t likely to need a service contract. So, in a nutshell, before you go
for any repair-type service contracts, you must have a clear understanding of what’s being promised in all of the fine print, and you must do a
thorough evaluation of your own needs and how you will be using the
item in question.
Here are some additional considerations:
■ Is the contract already covered, in full or in part, by a manufacturer’s warranty? This happens. A manufacturer will warrant its
product and another company—a different company offering
extended or other warranties—will accept payments for the same
protection.
■ What does the contract include? Labor? Labor and parts? Must you
pay for the repairperson’s travel time? Some contracts cover only
certain components, such as the motor in a washing machine, or the
heating elements on an electric range, or the picture tube on a television.
■ What if the repair is needed at night or on a weekend? A hot water
heater that fails on a freezing Friday night in February needs to be
fixed before Monday morning. If the service contract doesn’t specify
seven-days-a-week repairs, a costly overtime charge could result.
■ Does the cost of the service contract rise as the item ages? It likely
will. Naturally, expected repair costs are minimal during the early
life of most appliances and major components. Ask about maintaining the contract in the third, fourth, fifth, or later years.
KITCHENS
■ Never take a salesperson’s word for what a contract covers. He or she
may forget important details or may misunderstand the terms. Find
out what a contract includes and excludes by reading it yourself. Pay
attention to items such as the following: Where will the product be
serviced? In your home? In a repair shop? In a manufacturer’s service center? Is the contract transferable if you sell the item? How
much time do you have to decide if you want the service contract?
■ Find out who is offering the service contract: the retailer or dealer
you’re buying the item from, the manufacturer, or an independent
third party?
■ Find out who will be performing or who you can have do the repairs.
Regarding appliances or individually manufactured units, will repairs
be made by technicians trained to service your product?
■ To check on the reputation of a company offering service contracts,
ask the Better Business Bureau or your local consumer protection
office.
APPLIANCE CHECKLIST ✔✔✔✔✔
1. Prepare before you buy. Compare and evaluate products and services.
2. If reasonable, favor established, reputable, local retailers.
3. Buy quality. Generally, select appliances and other items with established brand names.
4. Always ask for a demonstration.
5. Ask about parts and service availability.
6. Favor service contracts (or “repair insurance”) if you plan to give
unusually rough use to whatever you’re buying.
7. When purchasing items for normal use, buy models offering superior
performance and maintenance records, and you won’t need a service
contract.

HOW TO BUILD IT
Refrigerators
A refrigerator should be large enough to accommodate your
expected family size and still be able to take care of all the entertaining you plan. Consider which modern options, if any, you’d like, such
as automatic ice maker, fast freezer, or ice water spout. Make sure the
model you want will fit into the spot allocated on the plans. And
whenever possible, the refrigerator door should be reversible, so with
a simple changeover it can open from the right or the left, in case you
want to remodel some day or relocate.
Here are some available options for refrigerators:
■ Adjustable rollers at the base so the unit can be moved without
being lifted.
■ Reversible doors.
■ Recessed handles.
■ A textured door that won’t show dirt and smudges.
■ A door heater to prevent excess condensation during hot,
humid weather.
■ Door lights that signal problem conditions such as power out-
ages, an open door, warm inside temperatures, and dirty condenser coils.
■ An automatic ice maker with dispensers for crushed or cubed
ice and chilled water, conveniently illuminated by a nightlight.
■ A front-door compartment that enables a built-in counter to
drop out from the door to provide easy access to often-used
items such as milk or juice.
■ If lack of space is a problem, some units come only 24 inches
deep.
■ A self-defrosting freezer.
■ Ice trays and buckets.
■ Removable door dikes that allow you to completely remove the
ice bucket.
■ Removable covered storage containers/dishes that are designed
for freezer, microwave, and dishwasher use.
KITCHENS
■ A vacation economy setting.
■ Adjustable internal and door shelves.
■ Humidity-controlled crispers.
■ Extra cold meat compartments.
■ Egg storage bins.
■ Extra deep, movable door storage bins for gallon containers,
3-liter bottles, or six-packs.
■ Movable retainers on door shelves to keep small, tall, or oddly
shaped items in place.
■ See-through compartments allowing viewing of food without
opening them.
■ Sealed snack pack compartment for keeping items such as cold
cuts and cheeses fresh.
Ovens
The oven can be a part of the cooking range, situated under the
burners, or it can be a separate unit built into the kitchen cabinets.
Consider a double oven if you do a lot of baking or entertaining. Make
sure the ovens aren’t placed next to the refrigerator where cooking heat
could affect the operation of the refrigerator.
Here are some available options for ovens:
■ Self-cleaning.
■ Electronic ignition. This takes the place of standard pilot lights
in gas ovens, to save on fuel.
■ Broiler pan/rack.
■ A window plus a hand towel bar on the oven door.
■ A clock with an automatic timer.
■ A removable oven door.
■ An electronic meat thermometer.
■ An automatic rotisserie.
■ Chrome finish for easy cleaning.
■ A porcelain enamel-on-steel finish is also excellent.

HOW TO BUILD IT
Cooktops
The range or top burners can be a separate unit built into a countertop, with at least four individual burners. In some makes, the burner
tops can be temporarily removed so other cooking devices such as
grills and rotisseries can be substituted.
Popular new types of electric cooktops can be purchased with
sealed elements that replace hard-to-clean drip bowls. Food spills end
up on the cooktop around the heat element where cooler temperatures
will not “bake” the spilled material onto the finish.
There are two kinds of new cooktops: inductive and glass ceramic.
Inductive cooktops are made with electric coils located beneath a glass
ceramic surface. Magnetic energy generated between the cooktop coils
and the pots and pans placed on the cooktop surface creates heat that
cooks the food. Because the glass ceramic cooktop surface is nonmagnetic, the current flows through it, reaches the metallic pots and pans,
heats them but leaves the rest of the cooktop surface cool to the touch.
Cooking on induction stovetops has certain advantages:
■ Cooking starts or stops immediately, with no preheating or
cooldown time required. This means you can bring milk that is
about to boil over back to the preboil temperature within a second of the heat being turned down.
■
Cleanup is simple because spills don’t bake on.
■
Only the part of the cooktop that comes in contact with the pan
heats, which helps to save energy.
■
It’s safer than heating with other types of cooktops.
■ Glass ceramic cooktops use halogen lamps that provide instan-
taneous heat on demand. A resistance coil around the element’s
outer edge assures even heat distribution.
■
Cleanup is easy because the surface of the cooktop around the
elements remains cool.
■
Heating is uniform across the element, and heat control is very
precise. The reheating ability of the elements is extremely rapid.
■
For safety, temperature limits are employed to prevent heat
surges and to protect the elements from overheating.
KITCHENS
Other considerations for cooktops include the following:
■
Grime-resistant control knobs are the best. The most popular are
plastic injection-molded knobs with markings that won’t rub off
and are flush with the knob so they don’t collect grease, dirt,
and grime.
■
Removable cooktop sections that can be replaced with a grill,
rotisserie, or griddle having easy-to-clean nonstick finishes.
■
If the cooktop is mounted as part of a range, a cooking light
should be furnished.
■
“On” indicator lights will remind the cook when a cooktop surface unit is turned on.
■
Some solid disc units contain temperature limits that will automatically reduce heat if a pot boils dry or if a unit is accidentally
left on without a pot or pan on its surface.
Cooktop Ventilation
Whether gas or electric, most grill-cooktops have built-in ventilation systems. Their downdraft designs pull smoke, odors, moisture,
and grease from the cooktop through a vent to the outside. This setup
offers several advantages over ventilation that’s positioned above a
cooktop.
■ A downdraft system uses a quieter and less-powerful fan than is
required of an overhead ventilation hood.
■
It provides design options for kitchens that can’t accommodate
updraft or overhead ventilation systems.
If your cooktop won’t have a built-in downdraft ventilation system,
the alternative is an overhead vent hood. Look for the following
options:
■
The fan should come with several speed settings.
■
It should use removable grease filters.
■
There should be a nightlight.

Microwave Ovens
Don’t overlook the inclusion of a microwave oven. Inexpensive
models are available for placing on a countertop or mounting in a wall
cabinet or beneath a hanging cabinet. They’re particularly useful in
conjunction with freezers, because they eliminate the chore of defrosting food beforehand. Combination microwave/convection ovens are
available that offer the best in both cooking methods.
Available features include the following:
■ Countertop, built-in, or beneath-cabinet mounts
■
A built-in clock/timer
■
Window and interior light
■
Multiple power levels
■
Auto start
■
Adjustable shelves
■
Meat probes
■
Humidity or weight sensors to calculate cooking time
■
A defrost setting
■
A ventilation system
■

■
A temperature cook/hold setting that allows food to be kept at a
desired temperature for up to one hour or until the clear/off pad
is touched
■
Wood-grain cabinets
Dishwashers
Some people would never have a kitchen without a dishwasher.
Others hardly ever use the one they have. It’s up to your own personal
preference. Here are some features to consider if you’re planning to
have a dishwasher in your kitchen:
■
A warning alarm that signals a blocked drain.
KITCHENS
■
An energy-saving option that will shut off the heater in the drying cycle to save energy when dishes can air dry overnight or
throughout the day.
■
A soft-food disposal.
■
A choice of wash cycles: normal, short, light, energy saver,
china/crystal, rinse only.
■
Changeable front panels that allow damaged panels to be easily
replaced or existing panels to be replaced with different color
panels to match changing decorating schemes.
Disposals
The disposal is another appliance that draws mixed reviews. Some
people love disposals—the way they can just whirr through almost
anything short of bones. Other people are afraid of them, of the noise
and the blades—can they trust them with children?
If you plan to include one in your kitchen sink, look for the following:
■
Stainless steel construction
■
A model insulated for sound depression
■
Continuous feed
■
A noncorroding nylon hopper and polyester drain housing
■
Child safety features
Food Processors
These appliances make it quicker and easier for both new and experienced cooks to tackle much of the work involved in food preparation. Small quantities of foods can be minced in seconds—onions,
garlic, parsley, raw meat, cooked eggs, practically anything. Look for
the following options:
■
Continuous feed for processing large amounts
■
An S-blade for chopping
■
A reversible slicer/shredder disc
■
Up-front controls for easy access
■
On/off pulse action

Automatic Chrome Can Opener/Scissors Sharpener
This appliance should provide the following features and advantages:
■
It will open cans, bags, jars, and bottles.
■
It will automatically power-pierce lid, open can, then shut itself
off. A magnetic finger securely holds lid.
■
The sharpener hones household knives, shears, and other cutting instruments.
Cordless Wet and Dry Vac
This appliance is designed for wet, soggy, and dry cleanup tasks.
■
It’s great to have close by for spilled flour, beans, liquids, potting
soil—almost anything.
■
One option to look for is a motorized brush attachment that
cleans carpets, upholstery, and bare floors.
■
Other popular attachments include a crevice tool, a ceiling
wand, a furniture brush, and a squeegee.

HOW TO BUILD IT
Sinks
Many of the best kitchen sinks are made of either stainless steel or
enameled cast iron. Both are easy to keep clean and will retain their
good looks over the years. There are also porcelain-on-steel sinks that
look like cast iron but are hard to keep clean, chip easily, and lose their
gloss quickly. The more expensive line of stainless steel sinks contain
higher percentages of chrome alloys, which provide better appearances and a reduced tendency toward “water spotting.”
The style of sink you choose should have at least two wash bays or
bowls and a rinse spray gun.
A triple-bowl kitchen sink (Fig. 25.4) allows hand dish washing in one
bowl, rinsing in a reduced-size center bowl, and placing items in a drying
rack staged in the third bowl. This quick-wash and dry system enables
dish washing to be completed while the washing water is still hot.
If desired, an optional garbage disposal makes cleaning dirty dishes
and cookware faster and easier, but can be a headache if not properly
used and maintained.
It’s not absolutely necessary, but it sure is handy to include an automatic dishwasher. If you decide on one, place it next to the sink and be
sure to allow at least 18 inches between any side wall or counter running at right angles to the machine’s front. If you cram a dishwasher all
the way into a corner, then two people won’t be able to load or unload
it at the same time.

KITCHENS
SINK/PULLOUT SPRAY FAUCETS
Consider purchasing a comfortable, palm-fitting pullout main
kitchen sink faucet. It will allow easier washing and rinsing of larger
items in the sink and the filling of containers that would otherwise be
too large for a fixed sink faucet spout to handle. With fingertip control,
this faucet’s flow can change from an aerated stream for rinsing vegetables or cleaning around the sink, to a functional steady stream for
basic sink use.
FAUCET FILTERS
When choosing a kitchen sink faucet, consider one with a functional “carbon block” filter. Unless you have included a main house
water filter with your plumbing, take a look at faucets that come with
replaceable filters right inside the faucet’s neck, out of sight, and available in pullout models. These faucets and their filters accomplish the
following:
■
Reduce common impurities such as chlorine and lead.
■
Should not remove beneficial fluoride.
■
Improve water taste and reduce odor.
■
Can typically be switched from filtered to unfiltered flow.
■
Filter cartridge offers quick and easy replacement, right at the
sink.
■
Inconspicuous filters are positioned out of sight, inside the
faucet.
■
Units are stylish.
■
Are available with built-in filter life indicators to provide visual
and audible feedback signals for remaining filter life, for showing water is being filtered, and monitoring battery strength.
CABINETS
Kitchen cabinets have always been the focal point of any kitchen
(Fig. 25.5). More than anything, they set the flavor of the room and
make or break its appearance. It’s no coincidence that they’re usually
615

the first to be changed when kitchens are remodeled, and countless
home improvement contractors earn their living by replacing or giving
facelifts to kitchen cabinets. Nowhere else in the typical house are so
many different items kept. If it weren’t for kitchen cabinets and drawers, chaos would prevent numerous cooks from staying organized and
efficient in the kitchen.
Most kitchen and other cabinets (bathroom cabinets, for instance)
are manufactured in one of three ways: custom-made, factory-made,
and custom factory-made.
Custom-made cabinets are constructed in a local cabinet shop
according to your exact plans. Such a method offers practically unlimited selection as to material, design, and finish, but it’s also the most
expensive. If your needs are unusual, though, custom-made cabinets
could be your best option. Your builder should get bids from several
cabinetmakers before you make a final decision.
KITCHENS
Factory-made cabinets are built to the specifications of the different
lines the factory carries. Your choices are thus limited in the selection
of material, design, and finishes. These cabinets range in price from
inexpensive to very expensive, depending on the individual manufacturers and lines.
Custom factory-made cabinets are assembled at a centralized plant
in response to orders taken by local kitchen cabinet outlets. You can
expect a much greater choice in material, design, and finish than with
factory-made cabinets. Prices are usually less than those of custommade cabinets and more than those of the medium and economy
grades of factory-made models.
For your kitchen cabinets, give careful thought not only to cost, but
to what cabinet style, type, sizes, quantities, and accessories will best
suit your needs.
Cabinet Considerations
■ Base cabinet depth should be around 24 inches.
■ The floor-to-countertop height should be about 36 inches.
■ Cabinets installed over countertops should be at least 12 inches
deep and about 30 inches high.
■ There should be about 18 inches of clearance between the coun-
tertop and the bottom of wall cabinets.
CABINET STORAGE CHECKLIST
✔✔✔✔✔
Kitchen storage space is obviously most efficient when it’s conveniently located. This is particularly true in the cooking area, where most
kitchen work is done. It follows that, when planning a kitchen layout
you must arrange for enough storage space of the right kinds to be
made available near each of the major appliances for utensils, foods,
seasonings, cleaning supplies, and other items that are used at the various work stations.
Here are some sample checklists of items you should plan storage
space for near the kitchen cooking range, refrigerator, and sink.

Types of Cabinets
There are four basic types of cabinets you can select from: unfinished wood cabinets, stained wood cabinets, painted wood cabinets,
and wood and plastic laminate cabinets.
UNFINISHED WOOD CABINETS
Like any unfinished product, unfinished wood cabinets can be purchased at a substantial savings if you decide to finish them yourself or
have the house stainers do the job for you, before or after the cabinets
are installed. If this method is selected, the cabinets can be finished off
to exactly match other woodwork and trim throughout the house.
STAINED WOOD CABINETS
Stained wood cabinets are finished at the shop or factory in a carefully controlled environment that ensures an excellent application
and curing of the many finishing coats that are available.
WOOD AND PLASTIC LAMINATE CABINETS
Wood and plastic laminate cabinets are finished either at the factory or at a local shop. They’re constructed of wood or a wood product
619
620
HOW TO BUILD IT
such as particleboard, and then covered with a plastic laminate. The
plastic laminate offers a wide variety of bright and wood-grain colors
and patterns, and is easy to clean.
Special Cabinets
Apart from the standard cabinets that are set squarely against a
wall, other units are available to fill special storage space needs.
■ Pull-out disposable and recyclable bins in the kitchen will per-
mit easy handling of those materials without having to access
the garage frequently.
■ Two-way cabinets have doors on both their fronts and backs.
When suspended from a soffit over a counter peninsula or
island, they permit you to put dishes away from the sink side
and to take the same dishes out from the dining-room side when
setting the table. Matching two-way base cabinets can also be
purchased.
■ Quarter-round cabinets are used at open ends of cabinet rows to
give a rounded-off look and to permit items to be stored on the
front or side of the cabinet from several angles. Similar halfround cabinets and shelves can also be purchased when
needed.
■ Mixer cabinets are used for storing large electric mixers. A
mixer cabinet is a base unit with a shelf that pulls out and up.
■ A bottle cabinet is a base cabinet with pullout trays that are
eggcrated to hold bottles.
■ When wall and floor cabinets are located on both sides of an
interior corner, a revolving round “lazy Susan” cabinet tray
arrangement can make good use of otherwise hard-to-access
space.
Cabinet Slide-Out Shelves
Consider having some of your lower shelves as pullout trays that
will give greater visibility and ease for reaching their contents. Heavy
pots and items can be brought into full view and easy reach by simply
pulling a tray forward. Vertical drawers are particularly satisfactory
KITCHENS
below the sink, where often-used dishpans, strainers, and colanders
are kept.
Special drawers are also available with dividers for canned goods if
there is no pantry. Bread box and slide-out vegetable bins are good for
storing onions and potatoes.
VENTILATION
A poorly ventilated kitchen will suffer from chronic condensation
and the odors of your last meal. In addition to strategically placed windows and sliding doors with screens, an overhead lighted hood with a
fan that’s vented directly to the outdoors is one of the best overall solutions. But a fan built into a counter range top and vented to the outdoors is also very popular and effective. When considering hood
exhaust equipment, look for:
■ At least three fan speeds
■ Multiple light settings
■ Filter cleaning reminder
■ Seamless construction in a metal hood; otherwise grease can
collect under the edges where joints are welded.
■ Hooded vents should be vented directly to the outdoors with
straight, rigid, smooth, fire-proof metal sections to provide practically effortless airflow.
■ The terminal (outdoor) vent should be kept as far as possible
away from windows so exhausted air won’t draft back into the
house when the windows are open.
LIGHTING
The kitchen should have enough illumination, day or night, for
cooking, work, or socializing. If possible, locate a window over the sink.
Large windows and skylights are always helpful to the family chef.
A kitchen should have task lighting installed under wall cabinets,
for the sink, range, and counters. The same goes for all other kitchen
work areas and centers.
621
622
HOW TO BUILD IT
Consider fluorescent lights underneath cabinets that hang from a
soffit over countertops to illuminate counter work surfaces. Plan
recessed lights in plain soffits above work counters and ranges (if a
light isn’t already in a range hood).
There should be separate lighting over the main kitchen area. A
light over a table with chairs or over an eating nook should be dimmercontrolled.
KITCHEN WALL FINISHES
The walls of a kitchen, especially the wall surfaces above the work
counters, should be finished with an easy-to-clean material. Three
popular, functional wall finishes are as follows:
■ Fabric and vinyl wallpapers—these have excellent surface
washability and durability characteristics. They come in a wide
variety of colors and patterns.
■ Predecorated wallboards—these colored and patterned vinyls
come in factory-manufactured sheets that are easily cut to fit
and applied to the walls.
■ Ceramic tile—ceramic tile is durable and attractive, but it
requires a little more maintenance and effort to keep clean.
MISCELLANEOUS
1. Make sure there are enough electrical outlets along the
countertops.
2. Consider locating broom and pantry closets in or near the
kitchen.
3. Specify on your prints the make, model, color, and style of the
sink, refrigerator/freezer, dishwasher, range, oven(s), microwave,
garbage disposal, and exhaust system.
4. Consider having a small desk in the kitchen where you can sit
down to thumb through cookbooks, make out shopping lists,
check bills, and make telephone calls. The desk should be large
enough to accommodate a computer, too, for allowing Internet
KITCHENS
access to cooking information and to enable family members to
perform computer work between kitchen tasks.
5. A portable telephone in the kitchen is a must. If the phone rings
while you’re cooking supper, you can bring it over to the range
top and keep stirring that sauce or stir frying those potatoes
while talking.
6. Every surface in the kitchen should be easy to clean with a
damp sponge: countertops, walls, floors, appliances, and cabinets.
7. There should be plenty of receptacles for portable appliances
such as coffee makers, blenders, toaster ovens, radios, bread
machines, and electric skillets.
8. Ground-fault electrical circuit interrupters (GFCIs) should be
supplied in all kitchen and bathroom receptacles.
9. A fire extinguisher should be within an easy reaching distance
to the cooktop, and smoke alarm protection should be included
near the kitchen.
10. Allow enough space for at least two waste containers: garbage
and trash.
➤➤➤➤➤ POINTS TO PONDER
1. When designing a kitchen, carefully consider its four major components: dining facilities, countertops, cabinets, and appliances.
2. Of all parts of a kitchen, countertops (or food preparation tops)
are used the most. Plan generous amounts of them.
3. Make sure there are plenty of GFCI electrical outlets along the
countertops.
4. Kitchen cabinets have always been the focal point of any
kitchen. More than anything else, they set the flavor of the
room and make or break its appearance. It’s to your advantage
to select quality-grade cabinets. They’ll look better and wear
longer.
5. Consider installing broom and pantry closets in the kitchen, if
there’s enough room. Cookbook shelves and a small computer

desk/work station have also become popular modern kitchen
features.
If possible, a window should be located behind or to the side of
the kitchen sink, to provide natural lighting during the day.
Because food preparation tasks entail lots of fine handwork,
plan enough task lights into the kitchen. Recessed or track
lighting units make excellent choices.
Remember, when planning the location of appliances, that certain units, such as trash compactors, garbage disposals,
blenders, food processors, and stove/cooktops with front-unit
controls, should be off-limits to young children.
Good ventilation in a kitchen is a must. That can include window/screen units, sliding glass door/screen units, and rangetop
fans.
The walls of a kitchen, especially the wall surfaces above the
work counters, should be finished with durable, easy-to-clean
materials.
Consider running two phone lines into the kitchen, in case the
household cook plans on being on the Internet while preparing
meals.

Floor Coverings
T
he selection of a particular floor covering depends on where it will
be used, its appearance (available styles and colors), durability, ease
of care and maintenance, price, and the buyer’s personal taste. It’s an
excellent idea to visit a number of large home stores and specialized
flooring stores to see available floor coverings, and get a feeling for
what’s new. There are certainly many floor coverings to consider when
planning your home, including carpet, laminate, vinyl, linoleum,
wood, cork, bamboo, tile, stone, brick and concrete.
CARPETING
An almost limitless array of carpeting is manufactured for homeowners to choose from. Practically any quality, basic material, texture,
color, weave, or price range can be had for the asking. It’s an all-around
excellent floor covering that can literally be used anywhere in a home.
Certainly, carpeting is an interior decorator’s dream because it can
create as many moods as colors can influence. It can stretch small
spaces into large, and shrink large spaces small. It can supply a rich,
modern look to a room or create a statement of cool neutrality. It feels
wonderful beneath bare feet and is equally enjoyed by small children
who can tumble and fall on it without injuring themselves. It helps

HOW TO BUILD IT
control sound from echoing through a home by absorbing noises and is
relatively simple to replace when worn out.
On the other hand, it’s tough to remove a cupful of spilled grape
juice from a lily-white shag. Carpeting shows various stains and soils
and can pose big cleaning problems if chewing gum, grease, ink, or
various foods and drinks become embedded in its yarn tufts. Pet odors
can also find refuge in carpeting, and during times of low humidity,
static electricity can collect and shock people who touch metal lamps
or even one another. Also, when carpeting is installed in high-traffic
areas of a house, no matter what its quality, it will eventually show
wear paths, can be marred by dropped cigarettes, and cannot be refinished in any way. When soiled, carpeting needs either time-consuming shampooing or must be professionally cleaned.
There are carpets custom-tailored to solve a wide variety of problem situations: fibers designed to control the static electricity that
draws dust or gives shock on cold, dry days; carpets having soil resistance built right into the fibers themselves; industrial grade carpeting
designed to take unbelievable punishment, indoors and out; textured
carpets with a mixture of sheared yarns and loops engineered to camouflage stains and look good while doing so; and lustrous sheared
velours and velvets that look so plush that people are afraid to step on
them.
You can tell quality carpet by its material and nap or yarn density.
Wool makes excellent carpet, but it’s expensive. Nylon is the most
popular, accounting for over 75 percent of all carpeting manufactured
today. Acrylics, polyesters, rayon, and polypropylene or olefin are no
longer as popular as they once were, but are all still used for specific
applications, the latter, for instance, in kitchens and wherever indooroutdoor carpeting is needed.
Carpets used to be woven, but are rarely woven anymore. Instead
they’re tufted—a process by which yarns are looped through a woven
backing then locked into that backing with an adhesive and then
another thin layer of backing. Then the yarn loops are cut or sheared to
various lengths. The higher quality carpet contains a higher density of
yarn, or more yarn per square inch. The higher the density of yarn, the
greater the carpet wearability.
Because so many varieties of carpeting exist, here are some guidelines to help you plan the carpeting for your house:
FLOOR COVERINGS
1. The first decision to make is one of style. By area, do you want a
plush, a shag, or some other style better suited for each application. After you narrow down the style, begin comparing fibers
available in each of the style groups you’ve selected. A general
rule is to seek deeper and denser piles (the configurations of the
fibers) than you think you’ll need. Remember that shag carpeting is intentionally manufactured with low-density yarn to
achieve the “shag” look.
Two of the most popular styles of surface texture for carpeting are the sculptured and the plush. The sculptured style is
composed of designs created by alternate areas with and without heavy pile. The plush type has a constant pile thickness and
is more likely to show footprint indentations.
Another texture is the level loop pile, which wears well and
hides footprints nicely.
A fourth style is the frieze or twist type, which also thwarts
footprints and hides dirt and dust fairly well. Like the level loop
pile, the frieze or twist carpet stands up to rough use. And if it
has a level surface, it’s easy to keep clean. Frieze is ideal for
installations where multiple small seams must be matched—for
wrapping carpet around and between handrail supports on a
stairway, for example.
2. When checking for carpet density, watch out for crimp. Crimp is
exactly what it sounds like: mechanically induced zigs and zags
in the individual carpet fibers that add bulk and fullness. A
given amount of crimped fiber will fill more space than can otherwise be filled with the same quantity of regular, straight fibers.
The actual crimping of the fibers is on such a tiny scale, it can’t
be seen at a casual glance. When crimped fiber is spun into yarn,
air is captured between the zigzags; the yarn then looks straight
and solid, but at the same time has a fuller, fluffier look than the
noncrimped versions.
This crimping technique is used to make “high bulk” yarns
that are fluffed or tufted into some very stylish, elegant carpeting. It’s one way to obtain a plusher-looking carpet without
encountering a higher expense in the process. Crimped-fiber
carpeting might look good at first. It might feel and even sound
good, but all a consumer really gets is the same amount of fiber
627
628
HOW TO BUILD IT
that’s available in more “honest” versions with thinner piles—
plus a lot of air.
3. When choosing carpet styles and types, consider the wear that
they’re likely to receive. You’ll probably want the most beautiful
carpet in your living room, but if the room will see heavy family
traffic instead of being just a visitor’s parlor, then you might be
further ahead to avoid light-toned solid colors and favor an antisoiling plush or textured carpet instead. In general, when it
comes to the busier areas in a home—the living room, family
room, halls, and stairways, for instance, you’ll do better with
carpeting that will stand up to the traffic it receives. Bedroom
carpets receive relatively light duty and thus can be good places
to either economize or go luxury.
4. Most carpeting should have a padding of some type laid beneath
the entire surface covered. Padding helps lengthen a carpet’s useful
life by absorbing much of the footfall pressure that would otherwise
grind the carpet backing against the hard and potentially raspy surface of the floor decking. It also makes a carpet seem plusher than
the carpet really is by softening the impact of a person’s footfalls so
that walking on such a surface is more comfortable.
Various paddings are available, manufactured from hair, felt,
rubber-coated jute, cellular rubber, high-density sponge, latex
foam rubber, and urethane foam. All are acceptable when purchased in 1⁄4- to 1⁄2-inch-thick layers.
5. Carpeting should be installed on only smooth surfaces that are
relatively uniform and ridgeless. Whenever a separate cushion
or padding will be used, such undersupport should have all necessary seams covered with tape.
6. Carpeting should be planned so the least number of sections and
seams will be needed. When possible, the seams should be positioned in low-traffic areas. Carpeting should always be laid in
the same direction; that is, a butt end of a fresh roll shouldn’t be
seamed to a side of a previous roll.
Types of Carpeting
Here are brief introductions to the various types of carpeting materials available.
FLOOR COVERINGS
NYLON CARPETING
Nylon can go by various brand names such as Antron, Anso, Ultron,
and Enkalure II. By any name, nylon is the most popular carpet available. It’s especially good for entrance halls and stairways where traffic is
heaviest. It can be purchased in many bright colors, has excellent resistance to abrasion and overall strength, and is relatively inexpensive.
Advantages
1. Fairly inexpensive to produce and purchase.
2. Available in a huge quantity of styles, textures, and colors.
3. Good to excellent texture retention.
4. Good wet cleanability.
5. Excellent durability.
6. Good to excellent appearance retention.
7. Easy to maintain.
8. Excellent resistance to abrasion.
9. Good to excellent resistance to alkalis and acids.
10. Excellent resistance to insects and mildew.
11. Good resistance to compression and crushing forces.
12. Good resistance to staining.
13. Long life expectancy.
Disadvantages
1. Nylon carpeting in particular needs a good backing material to
attain dimensional stability.
2. Tends to pull and fuzz when abused.
3. Can retain oil and soil and “look dirty” easier than several
other synthetic fibers can.
4. Some discoloration might result from prolonged exposure to
sunlight.
5. Nylon has more sheen than wool and some of the other
synthetics.

HOW TO BUILD IT
6. Can develop static buildup.
7. Offers little protection against cigarette burns.
ACRYLIC CARPETING
These synthetic fibers closely resemble wool in texture, appearance, and abrasion resistance. Some acrylic carpeting, though, is very
flammable. Due to their resistance to staining and soiling, and their
low-maintenance demands, acrylic carpeting works well in kitchens,
bathrooms, basements, porches, patios, and poolside areas—wherever
dampness could be a problem, or spills are likely to occur.
Advantages
1. Good colorfastness, with good resistance to sunlight.
2. Resembles wool in appearance and texture.
3. Resists aging well.
4. Good texture retention.
5. Good to excellent wet cleanability.
6. Good resistance to static buildup.
7. Good to excellent resistance to staining and soiling.
8. Excellent resistance to insects and mildew.
9. Good resistance to alkalis and acids.
10. Good resistance to abrasion.
11. Good resistance to compression and crushing forces.
Disadvantages
1. Offers little protection against cigarette burns. Some acrylics
burn very easily.
2. Tends to pull and fuzz when abused.
3. Some loss in textile strength upon prolonged exposure to sun.
MODACRYLIC CARPETING
Modacrylic carpet fibers are acrylic fibers, chemically modified to
reduce their flammability. They wear and look like acrylic carpeting.
FLOOR COVERINGS
POLYPROPYLENE OLEFIN CARPETING
Polypropylene olefin is synthetic material that has one of the lowest moisture absorption rates of all carpet fibers. It’s easy to clean and
very resistant to stains and soils. It can be used instead of acrylics in
kitchens, bathrooms, basements, porches, patios, and poolside areas.
Be aware, though, that it isn’t as resistant to compression or crushing
as the acrylics, and doesn’t retain its texture as well.
Advantages
1. Good appearance retention.
2. Easy to maintain, with excellent wet cleanability.
3. Good durability and resistance to aging.
4. Excellent resistance to staining and soiling.
5. Excellent resistance to abrasion.
6. Good to excellent resistance to alkalis and acids.
7. Excellent resistance to insects and mildew.
8. Can be treated by the factory to give good resistance to direct
sunlight.
Disadvantages
1. Does not afford much protection against cigarette and other
burns.
2. Has only a fair resistance to compression and crushing forces.
3. Has only a fair retention of texture.
POLYESTER CARPETING
Polyester makes an attractive carpet with many fine features, but
it’s less favored than nylon, acrylics, and polypropylene because of its
resiliency deficiencies.
Advantages
1. A soft luxurious appearance.
2. Good colorfastness.
631
632
HOW TO BUILD IT
3. Excellent resistance to insects and mildew.
4. Less static prone than wool.
Disadvantages
1. Resiliency of polyester is somewhat less than that of nylon and
some other types so that dense, deeper pile construction is
needed for the same performance.
2. Stains easily with oily materials.
3. Prolonged exposure to sunlight will result in some loss of
strength.
RAYON CARPETING
Rayon is not generally recommended over any of the others. It soils
easily and gives poor resistance to abrasive wear.
Advantages
1. Unaffected by most acids and solvents.
2. Can be an attractive flooring in areas of light usage.
Disadvantages
1. Poor resistance to abrasion.
2. Soils rapidly.
3. Fuzzy types are very flammable.
WOOL CARPETING
When it comes to beautiful, durable, top-of-the-line carpeting,
there’s no doubt that natural wool fiber leads the pack. Wool is a wonderfully durable fiber that has yet to be surpassed for its excellent
appearance retention and resilience. Carpet wools are as varied as the
different types of sheep across the globe, with fibers that range from
fine and lustrous to coarse and springy.
Advantages
1. Excellent appearance and texture retention.
FLOOR COVERINGS
2. Excellent durability.
3. Good to excellent ease of maintenance.
4. Warm and comfortable to the touch.
5. Dyes well.
6. Good resistance to abrasion.
7. Good protection against cigarette and other burns.
8. Excellent resistance to compression and crushing forces.
9. Good resistance to staining and soiling.
Disadvantages
1. Expensive.
2. Offers only fair resistance to alkalis and acids.
3. Possesses only fair to good wet cleanability (but many other
cleaning methods have been developed over the years).
Carpet Protection
Although frequent vacuuming prevents soil and miscellaneous bits
of debris from becoming ground into carpeting, it also makes sense to
start out with a quality grade of carpet that already has built-in protection engineered into its construction. When reviewing carpet specifications and manufacturers’ claims, look for the following:
■ Stain resistance. Spills should bead up on the carpet’s surface,
allowing easy blotting for quick removal.
■ Soil resistance. Soil resistance helps repel dirt and prevents it
from becoming embedded and damaging to the carpet’s backing.
It also helps prevent dust and tiny bits of debris from sticking to
individual carpet fibers, making vacuum cleaning and other
soil-removing methods far more efficient.
■ Static resistance. Static electricity can build up to startling lev-
els and may pose serious problems to youngsters, senior citizens, or anyone who happens to receive an unexpected sharp
shock after touching a piece of metal such as a lamp base while
going about routine activities at home.
633
634
HOW TO BUILD IT
■ Wear resistance. This quality is typically reflected in the length
and breadth of the carpet’s warranty.
■ Color/fading resistance. This feature is especially important in
sunny climates and in contemporary homes using plenty of
exterior glass.
Carpet Warranties
Any carpet you purchase should be covered by a warranty against
manufacturing defects. The warranty comes directly from the manufacturer and is an assurance that the carpeting wasn’t made in a slipshod manner (or if it was, by accident, the company will replace the
damaged carpet or reimburse the owner). It’s the consumer’s protection against defects such as if the tufts pull out of the carpet, or if the
face of the carpet comes apart from the backing, or if the dye bleaches
out when shampooed.
Carpet warranties are very important, so important that you should
never even consider buying a carpet that’s not guaranteed against manufacturing defects. As important as such warranties are, though,
remember that they don’t guarantee performance over the long haul.

BUILT-IN CENTRAL VACUUM SYSTEMS
Central vacuum cleaning systems have come a long way since their
introduction decades ago. They’re now more powerful and more convenient. Main vacuum power units can be located in a well-vented utility
room, basement, or garage—away from daily living activities providing
quiet operation (Fig. 26.1). Tubing that runs beneath the floors or in
the attic from one end of the house to the other connects hose inlets
(Fig. 26.2) throughout the house. On many systems, when a portable
hose attachment is inserted into an inlet, the vacuum starts automatically. The long hose attachment enables the vacuuming of stairs, walls,
ceilings, and furnishings. The vacuum power plant is typically vented to
the outdoors—but not onto or near a patio, deck, breezeway, window, or
entrance.
FLOOR COVERINGS
635
Central vacuum systems are convenient for cleaning multistory homes
where you’d otherwise have to lug a portable unit up and down; they’re
also good for keeping basements, garages, and automobiles vacuumed.
Plus overall, the convenience and ease of using a central vacuum system
helps encourage household members to clean more frequently than they
otherwise might. Numerous cleaning attachments also make specific
vacuuming tasks easy.
There’s even vacuum dust pans, built into a cabinet toekick or baseboard, that accept dirt swept off vinyl, wood, concrete, and other hard
floorings. Great for kitchens, baths, laundry rooms, mud rooms—with
smooth flooring, they eliminate the need for dustpans or stooping. The
vacuum system automatically activates with the flip of a toe switch
(Fig. 26.3).

LAMINATES
Laminate floorings have recently found favor with builders, home
buyers, and remodelers, and for good reason. Various patterns and
styles can supply the look of wood, tile, and stone—without the
accompanying care and maintenance hassles. Laminates are typically
composed of four layers (if you count the printed photograph of the
wood, stone or tile finish as a layer). The top layer, also called the wear
layer, is usually made of an extremely durable material called aluminum oxide. The thickness of the aluminum oxide is often what sets
the price and warranty length of the particular laminate in question.
The thicker the layer of aluminum oxide, the more durable the product surface is. Beneath the clear surface layer is the decorative finish
(the wood plank or stone or tile appearance) layer. Supporting the top
layer is the middle or core layer which is often a sturdy fiberboard or
particleboard. The bottom layer can be made of laminated products
which sometimes include plastics and melamine. Together, the layers
are fused by pressure and heat into a user-friendly flooring. The wear
layer enables laminate flooring to withstand stains (even from notorious staining agents such as mustards, red wine, bleach, and some felttipped markers), impacts, and abuse that would damage most other
types of floorings.
FLOOR COVERINGS
It’s a good surface for high-traffic areas such as kitchens, recreation
rooms, or exercise rooms. It’s simple to care for and maintain, requiring little more than routine vacuuming and an occasional sponge mopping. It comes in a wide variety of styles, colors, and patterns that
imitate wood (narrow or wide boards), tile, and stone. The better models even have realistic, textured grains or surfaces that match the
wood, tile or stone appearances. Most laminates come in individual
boards having tongue-and-groove edges. The boards are most often
installed as a “floating floor” over a thin layer of foam, without nails,
screws or glue. Although wet areas such as bathrooms and laundry
rooms can potentially be a problem for laminates (water may leak
through the tongue-and-groove seams), that problem is sometimes
solved by using glue or sealants between each board. Check with your
contractor if you plan a wet-location installation.
VINYL FLOORING
Vinyl is a synthetic material made of petroleum products. Vinyl
flooring makes a fine floor covering for bathrooms, kitchens, recreation rooms, sunrooms, laundry rooms, or any other rooms for that
matter. It offers wide selections of patterns, colors, and even textures,
and is available at many quality levels and prices. Although it comes
in tile and long strips, most vinyl flooring is manufactured in wide
rolls so a room can be laid out with very few seams. Quality vinyl
resists grease and other staining materials, and is overall, very durable.
Lower-quality vinyl should be avoided. Some vinyl flooring never
needs waxing, while other vinyls might need waxing from time to
time.
Advantages of quality vinyl flooring
■ Wear-resistant.
■ Stain-resistant.
■ Scuff-resistant.
■ Tear-, gouge-, and rip-resistant.
■ Should not discolor from mold, mildew, or alkalis.
■ When installed properly, seams should not curl.
637
638
HOW TO BUILD IT
Vinyl floor considerations
■ Seams should minimized and protected by seam coats.
■ Vinyl flooring with greater percentages of vinyl makeup are
tougher and more cushioned than models having less vinyl
makeup.
■ Thicker vinyl floorings are more comfortable and tend to be
more tear- and puncture-resistant.
■ Ask if the vinyl flooring you’re considering comes in 12-foot
widths, to minimize seams.
LINOLEUM
Before vinyl appeared decades ago, linoleum ruled the kichens,
bathrooms, rec rooms, and laundry rooms throughout the country. The
“lin” in linoleum refers to linseed oil, which is a product extracted
from flax seed. For linoleum, the linseed oil is dried out and made into
a cement powder that bonds ground wood, cork, resins, and other natural materials into an extremely durable material that’s backed with a
jute fiber or similar layer. Linoleum, in improved versions, is once
again available. Don’t avoid considering it because you think it’s old
fashioned. It’s a natural, modern product that’s entirely recyclable, a
flooring that’s recommended for individuals who suffer from allergies
or asthma because it’s hypoallergenic. Manufacturers also claim that
linoleum does not emit gases, is a natural deterrent to bacteria, and
resists the transfer of static electricity. Linoleum is used in many of the
12-inch square (and larger) commercial tiles you see in hospitals,
stores, and other high-traffic businesses.
WOOD
Wood floor covering has been used for centuries. It comes in many
types and styles and can be used in almost every part of a house.
Wood flooring is available in hardwood and softwood varieties.
The hardwoods have excellent wearing qualities. The most popular
species are white and red oaks. Standard hardwood flooring boards
come in widths of 21⁄4 inches and random lengths. To achieve a more
FLOOR COVERINGS
custom look, oak flooring can also be supplied in random widths with
or without a distinct V-groove between the lengthwise side edges of
each plank.
Softwood floors really mean pine wood planks. They come in standard and random widths and lengths. It’s a lot less expensive than oak,
but pine will show wear more quickly than oak. On the plus side, pine
has a beautiful grain and takes staining very well.
Parquet flooring is another variety. It consists of small pieces of
wood pressed and bonded together in a square tile. A parquet floor can
be a thing of beauty, but it’s more troublesome to take care of than
plain plank flooring.
Wood flooring will not wear appreciably if its surface pores are
filled in and the entire top is sanded, sealed, and periodically resealed
with a protective finish of either layers of wax, varnish, shellac, lacquer, or hard polyurethane. If desired, wood stain can be applied
before the polyurethane. Polyurethane is available in a matte (soft
gloss) or a hard shiny finish. The choice is one of personal taste. In
addition to giving wood flooring a pleasant appearance, polyurethane
requires no waxing. Eventually, though, even polyurethane will have
to be reapplied.
Wood floors have good grease and other stain resistance and are
fairly simple to maintain.
While linoleum and carpeting must be torn out and replaced when
worn, wood flooring can be resurfaced. It’s the only floor that can actually improve with age and successive refinishings.
On the negative side, the periodic refinishings, with their laborious
sanding, can be expensive and time-consuming. Hardwood floors can
also be very noisy. You can soften up their effects by placing large area
rugs in the living spaces and by hanging substantial draperies in the
same room to absorb sound. And lastly, wood flooring not securely
nailed will squeak when walked upon.
CORK
No, not the champagne bottle stopper, but rather, a surprisingly
durable flooring or underlayment made of the replenishable bark of
cork oak trees grown around the Mediterranean Sea, in North Africa,
Spain and Portugal. Cork flooring has terrific sound absorption quali-
639
640
HOW TO BUILD IT
ties, and makes for an extremely comfortable surface to walk on. When
used as an underlayment beneath laminate, hardwood, and other
floorings, it greatly reduces the sound transfer below and above the
walking surface. Manufacturers stress that cork flooring, with appropriate finishes, is tough enough to install in living rooms, kitchens,
family rooms, hallways, practically anywhere except places likely to
get doused with water every so often, such as bathrooms and laundry
rooms. Home hobby areas and hobby craft spaces are good candidates
for cork, because users may spend a lot of time there on their feet, and
can benefit from such a cushioned surface.
BAMBOO
Like cork, bamboo is a replenishable material that has recently been
finding it way to flooring. Stronger than oak, bamboo is really a grass
that takes only about five years to grow into canes large enough for flooring use. It sounds too good to be true, because when pressed and formed
into boards, bamboo is beautiful, super-hard, durable, scratch- and
gouge-resistant, and will not absorb as much moisture as hardwoods
will. It’s produced in a variety of horizontal- and vertical-grain models,
colors, and board sizes. This flooring needs to be seen to be believed.
TILE
Tile flooring—individual square or other multisided tiles—come in
a full range of colors, finishes, and sizes in two popular types: ceramic
and quarry.
Ceramic tiles are generally glazed in bright, shiny colors and are
used to create custom floor designs or mosaics that set or follow a
room’s decorating scheme. Many ceramic tiles are made in Italy and
Portugal.
The term “quarry tile” is misleading. It isn’t actually tile that comes
from a quarry. Rather, it’s made from a mixture of clay, shale, and grit
that’s baked at high temperatures. Quarry tiles feature muted, earthen
tones that are not glazed or shiny. Their dull surfaces help create a natural look inside homes that are planned with unsurfaced or natural
building materials and decor. The term “quarry” really hails from the
old-fashioned word “quarrel,” which means a four-sided stone.
FLOOR COVERINGS
Tile makes a floor covering that possesses a lot of character, and is
often used in hard-service areas such as entrance foyers and patios,
and is equally at home in bathrooms, kitchens, and sunrooms. Tile is
ideal to use on floors that will be on the receiving end of passive solar
heating designs. During the day the tiles will soak up heat that will, in
turn, be gradually released during the evening.
Although tile is very durable and will withstand wear and tear
well, it has many seams and joints that are susceptible to cracking and
staining. These seams and joints should be periodically recoated with
an impervious surface sealer. Aside from the grout or other joint
cement, the tile itself requires little maintenance. For best results, with
the exception of bathrooms, tile should be laid in cement mortar over
a dropped or sunken subfloor.
Tile flooring has been around for many, many years, and lots of different types and grades of tile and substrates (material that tile is laid in
or set on) exist. Some tile is selected for its resistance to water absorption. Others for slip resistance, stain resistance, or (for outdoors use)
frost resistance. Final selections should be made only after consulting
contractors and manufacturers with considerable tile expertise.
STONE
If you elect to specify a natural stone floor in a foyer or room,
there’s no doubt that such a floor will be one of a kind. There are
dozens of colors and sizes of natural stones, from purple, red, and
black slate, to multitoned granites, colorful quartzites, and the softer
polished marbles.
Practically speaking, most stone used in today’s homes is either
slate or bluestone. Slate is a smooth gray, red, blue, or black sedimentary stone that splits easily and evenly into convenient slabs. Bluestone
is a sandstone that can be gray, green, blue, or buff colored. Their most
popular applications are foyers, hallways, kitchens, and sunrooms.
Although marble is the most luxurious stone that’s widely available, it’s a soft stone that tends (especially in the darker colors) to
scratch easily and to absorb stains readily unless covered with a few
coats of a good stone sealer. It’s also slippery when wet.
What all well-cared-for stone offers is natural beauty and durability, plus ease of maintenance. The seams and joints, however, will
641
642
HOW TO BUILD IT
need the same treatment as they receive with tile flooring—an impervious surface sealer.
Because natural stone is very heavy, depending on the thickness of
stones selected, floor joists should be installed 12-inch on center for
additional strength.
BRICK
If you’re considering tile and stone, you might as well look at brick,
too. It also comes in many colors, textures, and types. Brick is installed
and cared for in a similar manner to tile and stone. All three can add a
lot of character to select areas in your home.
CONCRETE
One more masonry flooring possibility is concrete. If you’ve never
seen a stained and finished concrete floor, imagine that you’re looking
at a floor that resembles buckskin suede, or a soft blue aged Italian
marble, or terra cotta in soft brown hues punctuated with bits of rust.
Circular saws can be used to cut the concrete surface to give to
effect of tile or cut stone flooring. Stained concrete can be used indoors
and outdoors. More and more independent contractors are learning
how to stain, etch, and seal thin and thick concrete slabs, which
results in competitive pricing. In addition, matching concrete furniture and countertops can be cast and finished—on site—to give a home
a one-of-a-kind decorative look.
FLOORING INSTALLATION CARE
■
The contractor should wait until the latter stages of construction
before the home’s flooring is installed—to prevent excessive
wear and tear.
■ No matter which floorings you select, make sure that when
heavy appliances are delivered, the flooring is protected by a
thin sheet of plywood or similar material.
■ Remind the contractor that no smoking is allowed. Brand new
floors can be badly marred by burn marks from dropped cigarettes or cigars.
FLOOR COVERINGS
■ Make a point to look closely at the flooring before releasing the
contractor’s final payment.
➤➤➤➤➤ POINTS TO PONDER
1. Don’t skimp on the padding when it comes to carpet. A thick,
resilient padding makes a carpet feel much plusher than it
would with a marginal, thin pad. Even though you can’t see it,
padding contributes greatly to lengthening a carpet’s useful life
by absorbing much of the footfall pressure that would otherwise grind the carpet backing against the hard, raspy surface of
the floor decking.
2. Through selective choice of colors and shades, carpeting can
create desired “moods” or “feelings” in rooms. It can be used to
liven up a simple floor plan, or tone down a starkly modern
room or dwelling. It can make a room or area look smaller or
larger. It can help separate one part of a room from another part.
3. Consider the type of use a carpet will receive before selecting
carpeting type, style, and color. Review your needs with several trusted carpeting distributors for suggestions and information on the latest offerings.
4. Become acquainted with the benefits available from laminate
flooring. If planning tile, stone, brick, or hardwood flooring,
investigate those looks in laminates, then compare cost, care,
and warranties.
5. Vinyl and linoleum floorings offer great appearance and wear,
at relatively low cost. Some so closely resemble stone, brick, or
wood that you can hardly tell the difference. Slip-resistant finishes are available for entrance foyers, kitchens, bathrooms, or
wherever flooring is likely to get wet. The better grades of these
floorings are virtually maintenance-free.
6. Major advancements have been made to all sorts of wood flooring products, coatings, and maintenance aids. Wood, when
properly installed and cared for, has excellent wear qualities, but
so do alternative flooring products such as cork and bamboo.
7. Selective use of tile flooring (sometimes with matching or contrasting wall tile) can add beautiful utilitarian, one-of-a-kind
643
644
HOW TO BUILD IT
floors to a home. The array of ceramic and quarry tile available
is mind boggling. Tile is also very durable.
8. Proper installation of tile flooring is critical to the long-term
life of the tile. Although the tile itself is rarely a problem, the
grout or joint cement can crack or loosen. The stability of the
base or underlayment the tiles rest on is also important. Make
sure the installing contractors are experienced or specialize in
laying tile.
9. Stone makes attractive, unique floors. Stones are also heavy
and hard and need professional installation techniques in addition to extra sturdy floor framing to support the weight. Brick is
installed and cared for in a manner similar to that of stone and
tile. Keep an open mind when it comes to the unique, costeffective looks of stained and sealed concrete.
10. Try to consider your entire flooring picture at the same time,
instead of going from room to room. Too many different types,
styles, and colors of flooring materials can result in a busy look
that you may quickly tire of. Real estate brokers and flooring
distributors can advise you on decorating traps to avoid.

Home Offices and Work Spaces
A
nyone paying attention to today’s demographics, social structures,
and modern career paths will acknowledge that the days of family
breadwinners starting out and finishing their careers with the same
company have changed. As large corporations continue to redefine
their own identities, and technological advances have powerful
influences over manufacturing techniques and products, more people
are finding themselves working out of their own homes or work
locations.
Magazines for entrepreneurs are flourishing. The large “office”
superstores are selling business supplies not just to small, medium,
and large companies, but to millions of small business owners who are
working a “regular” job during the day, then operating a janitorial service at night, or servicing furnaces on weekends, or buying and fixing
up small income properties. Many individuals, realizing how tenuous
their “regular” jobs are—and wishing to expand a part-time avocation
into a full-time career, carve out some space for themselves in a loft
above the garage, a corner of the basement, a spare bedroom, or a
study—even a small desk in the kitchen.
In truth, a home office can be many things. It can occupy a corner
of the dining room or be housed in the basement, a converted garage, a
spare bedroom, even an attic. The nature of the business is what typically dictates how large or elaborate the office may be. Ask yourself
645

646
HOW TO BUILD IT
questions. Will you be working alone, or will you eventually need
employees? Do you need space for a showcase for your product or service? If customers or clients need to access the office, then it probably
should be located and configured to give a favorable, professional
appearance.
Do you have special tools or supplies that require considerable
storage or must be kept away from curious children? What about the
electrical requirements? Computers, faxes, copy machines, printers,
and modems all need to be plugged in somewhere. Consider dedicated
circuits and surge protectors for your office equipment—so other
household appliances such as washing machines, refrigerators, coffee
pots, and the like won’t create internal power drains and surges that
could affect electronic equipment or the information stored within.
The surge protectors will also supply some margin of safety from
power surges that come from outside the home, too. Storms or power
blackouts can affect the way electricity is transmitted to your system.
These changes or spikes in voltage can cause major damages.
Other considerations include lighting requirements—certainly, a
productive office needs more light than that found in typical bedrooms or spare rooms. Ventilation, air-conditioning, and efficient
heating are also critical to the comfort and well-being of office occupants. Sound insulation is necessary in households with active family members.
OFFICE SPACE PLANNING
1. List your office needs, such as equipment, supplies, and furniture.
Will you need a mail room or setup? Video equipment? An exercise
area or room for a hobby? What’s important? It need not look like a
traditional corporate office to be effective. If fact, it should be
planned to enable you to carry out your activities in the easiest
ways possible. How will you be spending your time there? Put
some thought into this, so you can make those major activities your
main planning focus. Will you be in front of a computer a good portion of the time? Do you need a lot of flat, clear space? Is there a ton
of paperwork to keep track of? Do volumes and volumes of reference books need to be kept handy?
A few pointers include the following:
HOME OFFICES AND WORK SPACES
■ Consider setting up away from the busiest areas of the home.
This means away from the kitchen, front door, family traffic.
■ The office should be in a bright, well-ventilated area of the
■
■
■
■
home. Although many offices are constructed in basements, that
may not be your best option.
Resist the urge to aim your desk and chair at the door or
entrance of the room. Too many distractions.
Remove nonessentials from the office. Put seldom-accessed
items elsewhere.
Keep essentials at or within reach of your desk. Especially small
office supplies.
Realize that a home office does not have to be a separate room.
It can be part of a room, as long as there’s permanent work
space.
2. Sketch a plan, to scale. Putting your ideas to paper (or computer
monitor) will help you visualize the setup. Don’t fall into the trap
of winging the purchase of desk and file cabinets and other storage
components without knowing how everything will work together.
People sometimes purchase items that are too large for their
spaces, and the office room becomes too cramped for them to work
comfortably.
3. Figure the amount of storage you’ll need. There are two kinds of
storage requirements—for items you’ll need at hand, and materials
that don’t need to be close by. Try to arrange storage for “farther
away” items somewhere else—out of your office, to reduce congestion. But usually, additional storage capacity will be greatly appreciated. Desk space can quickly be taken up with computers,
keyboards, printers, faxes, and other bulky items. Make sure you
have some space to spread out working papers, books, and magazines you might need at the time.
4. Lighting can make or break an office. Certainly, bad lighting will
have an adverse effect on both a person’s mood and behavior, while
good, even lighting improves them plus productivity while contributing to a sense of well-being. Track lighting is an excellent
choice. It can be installed on walls or ceiling, saving desk and table
space for other uses. Dimmer switches are nice, too.
647
648
HOW TO BUILD IT
5. The decor of the room also helps create the right atmosphere for
working. Even if you’re the only one seeing it, it still matters. Certainly, if customers, clients, or visitors will be visiting your office,
consider that you are trying to build a business, and you want to be
taken seriously. The image you project through your office makes
an important contribution to your efforts. Let your work environment show that you are serious and organized about the tasks at
hand.
6. Noise control is important. Deaden the noise levels by installing the
thickest, heaviest carpeting (with a thick pad) you can find. It doesn’t have to be expensive—just substantial. You can also soundinsulate the walls, hang heavy drapes—cover those hard, echoing
surfaces with sound-absorbing materials. Also, work spaces, when
situated in the home, should have some sort of healthy take—
allowing occasional mental and physical breaks.
We suggest you combine, whenever possible, your office space
with a “health” space in which you locate the following:
Your business resources:
A personal computer with modem and Internet access.
A fax machine.
A printer.
A copy machine.
A double-line phone.
A file cabinet.
A reasonably nice desk, large enough to accommodate what
you need, with at least two pullout leaves for writing on or temporarily keeping resource materials at hand. Because most
desks become so cluttered with permanently positioned computer equipment and stacks of papers and files, there’s little
room for anything else.
8. A comfortable desk chair
