Expect healthy
indoor air quality and energy efficiency in your new home!
Retrofit your old home!
SPF -
otherwise know as Sprayed-in-place Polyurethane Foam is the
most effective way to achieve a complete air-seal for the
life-time of your home. Enjoy a much more comfortable
interior climate!

A garage is being
retrofitted to house a work shop. Situated in
Southern California, the interior heat never
reached more than 78 degrees after the
insulation - without air conditioning. Before:
the temperature reached 90+ degrees almost every
day! |

SPF seals cracks, seams and crevices in
the entire envelope of your home around the
perimeter of your home. Properly installed, foam
is guaranteed to stop all air leaks or drafts,
and even sharply reduces the chances for mold .
Foam bonds
tenaciously to just about any surface to create
a structurally sound air barrier. Just the air
tightness alone creates vastly improved energy
efficiency. High r-values improves the
performance even more!
What is the
best insulated device in your house? The
refrigerator, of course. And you guessed it, it
is insulated with foam. |

| The Highest
R-value in the Market
Insulation is commonly rated
in terms of thermal resistance: R-value measures resistance
to heat flow. The higher the R-value, the greater the
insulating effectiveness. SPF has the highest R-value (up to
7 per in.) of all standard insulation materials.
Reduces or Eliminates the Dew Point
By eliminating air flow in the cavity
(sometimes referred to as "convection looping", cold air
never gets to touch hot surfaces. The temperature difference
between inside and outside is gradual and thus reduces or
eliminates condensation. Besides outright plumbing or water
intrusion problems, condensation is the best source for mold
growth, and thus must be controlled.
Meets
Building Code Requirements.
Foam is approved by all three national
building codes. It will outlast your building. A number of
brands offer life-time warranties. Its exceptional thermal,
structural and quiet characteristics will save energy
expenses for the life-time of the building while improving
interior comfort dramatically.
Creates a Healthy Living Space.
Sprayed polyurethane foam effectively
protects your living space form unwanted moisture build-up
and condensation within the building envelope. Likewise,
foam does not have a cancer warning label unlike to
predominant insulation material. Installed by a
professional, the foam effectively seals any structure
against unwanted condensation and energy loss by convection.
Combined with up-to-date ventilation techniques, foam is the
first step toward creating the best, most habitable indoor
living space. It is indoor air quality that you can feel.
"Spray polyurethane
foam insulation can be applied to a home under construction
and will not only insulate, but will also reduce air leakage
in the building envelope."

Department of Energy Insulation Fact Sheet, August 1997
"Spray polyurethane foam alone can provide an air and
water-tight barrier."

There are many different formulas and
densities for various foam insulations on the market today. Choices include
open-cell foams which are economical and let the structure breathe. Closed-cell
foams provide higher R-value and they are waterproof. These foams are also more
expensive.
There are some DIY packages, but these are
only economical for the smallest projects. Most often, foam is installed by
trained professionals using equipment often valued more than $50,000. Obviously
this is CPI's business, we can provide you with an equipment solution and
training which will allow you start a very profitable business.
CPI's Polymer Spray Rigs allow contractors
to spray the entire range of different foams from block fill and cavity
insulation to roofing foam and coatings. Likewise, our equipment can handle open
and closed cell formulas.
An important characteristic of foams
is density which is expressed as pounds per cubic foot (lb/ft3 ) of
fully cured, installed foam. Higher density foams are harder and also
practically waterproof. If the perm perm rating is better than "1", the foam is
designated "waterproof". Closed cell foams are made of completely bubbles
"glued" together. Often cell foam has a significant percentage of "burst"
bubbles, thus creating a "labyrinth" of channels. All of this is obviously only
observable under a microscope.
As a rule, open-cell foams are around .5
density Also important is that the foam is water-blown meaning that there is
water in the formula which reacts into CO2 or carbon dioxide -
obviously deemed entirely harmless.
Closed-cell foam density is 1.8 or higher
(1.8 to 2: insulation foam, 3: roofing foam, higher density foams are used in
mining, molding and similar applications). The foams use CFCs such as 245fa, The
newest of these CFCs are relatively harmless (so do not attack the ozone layer
unlike earlier versions).
Both open cell and close cell foams
provide superior air sealing. Since the foams are spray-applied, the form a
monolithic barrier which will perform for a very long time. The choice of foam
depends on the particular application.
In any case, it is recommended to consult
with an insulation professional for the best decision. CPI can provide you with
the names of local experts.
