FAQ
What Is Soft Open Cell Spray Foam?
Open Cell
Foam is an insulation and air sealing system that is ideal
for residential applications. An application of Spray Foam
combines both a material and a service. The material
is a lightweight foam compound. The service
is custom installation of each stud cavity or rafter cavity of
a building directly on the construction site by trained, licensed
installers. It is much more than just another insulation.
By virtue of its low permeability to air infiltration, its adhesion
to other building materials and its flexibility, it provides good
air leakage control, moisture control, and sound control, as well
as great insulation. All in one application.
Does
Spray Foam Insulation Have Building Code Approvals
Yes! Foam has approval of all four major building codes in the
United States and the Canadian building code. In fact, it
is one of the most extensively tested insulation products ever.
Concern in the 1970's over the excessive off-gassing of an early
foam product called urea formaldehyde, and related concerns in
subsequent years over the health effects of other insulating products,
specifically asbestos and fiberglass, have resulted in some of
the most thorough and sensitive emissions testing of a new building
product to date. Based upon the results of this stringent
testing, Spray Foam met
the requirements of the building codes and subsequent re-certifications
as required on a periodic basis.
What
Are The Advantages Of Foam?
The major advantage of Spray Foam is that it does more than just insulate. It
also windproofs wall and ceiling cavities from air movement, with
a 3 1/2" sample of foam proving to be about 24 times less
permeable to air infiltration than a similar thickness of fiberglass
batt. In addition, the insulating power is not diminished
by lower temperatures or by air movement. Its R-value performs
as stated. By contrast, some building experts state that
an R-13 fiberglass batt in the presence of a 10 mile per hour
breeze (the real world) diminishes the insulating power of a batt
to an R-5! Hardly the kind of protection from heat and cold
you were hoping to arrange for your family.
What
Is Spray Foam Insulation Made Of?
Spray
Foam is an organic material
developed from products of the petrochemical industry. It
is a two component system that is sprayed like paint. The
chemical constituents are similar to those used in the manufacturer
of many products already in your home, such as upholstery foam
and the foam used for pillows and mattresses---although the properties
of the foam are different.
Spray
Foam is an environmentally
friendly urethane in which the ozone-robbing CFA's have been replaced
with air and water.
How
Long Does It Take To Cure?
The foam is created within
seconds after spraying. You can watch it expand within seconds
to 120 times its original volume, literally before your eyes. It completely cures within a few minutes.
Does
Open Cell Soft Foam Absorb Water?
No; it looks like a sponge but it is actually hydrophobic,
i.e. it repels water. If placed in water it will float,
and on removal, it will dry rapidly with no loss of insulating
properties. If you ever have a roof leak or plumbing leak
in your home which would soak the insulation, the water will ultimately
settle out and it will not damage the foam. We can't say the same for other insulation. Water breaks down the glue in a fiberglass batt so the batt is
destroyed and loses its effectiveness. Water also turns
cellulose (ground newspaper) to mush and it dries out VERY slowly
(have you ever tried to dry out a wet newspaper?). The cellulose
settles into a lump leaving a large un-insulated cavity in the
wall. Of course, if it remains wet long enough, it can cause
wood to rot and foster mold or mildew growth within your walls.
Does Open Cell Foam Entrap Water?
No. As stated above,
Spray Foam is an opened cell foam which is ideal for architectural
purposes. The foam breathes slowly, and any moisture in
the buildings' concrete or lumber can escape through the foam
as the building dries out, thus eliminating any risk of lumber
rot or mildew usually associated with materials that trap moisture.
How
Long Does Spray Foam Last? Does It Change Physically?
Aging is not an issue with
Spray Foam. It is inert, and its physical and insulating properties
are constant.
Environmentally
Speaking, Is There Anything To Worry About?
No. Spray Foam has been thoroughly tested. Once it has aged
for 30 days it is a stable product and no longer has any detectable
emissions. Spray Foam has
been used in many of the American Lung Association "Health
Homes" being built around the U.S. In addition to the
ALA use, Foam Insulation is also the only insulation that has an
Are
There Glass Fibers Or Formaldehyde In Spray Foam
No to both. Glass fibers
have been listed as a suspected carcinogen by the EPA and most
fiberglass batt manufacturers now print a warning label on the
wrapper. Formaldehyde was present in an early commercial
foam called urea formaldehyde which was also used in residential
applications in the early 1970's. Spray Foam is free of both glass fibers or formaldehyde and
is a great choice for insulating your new home.
