Spray Foam Uses |
|
|
|
|
Attics
-
30-50% of your homes heat and air conditioning is
lost through air leaks in your attic. The
chimney/stack effect draws air in at the soffit,
through recessed lighting fixtures, attic stairs,
wall outlets and mechanical penetrations (water and
gas service, telephone and cable connections, etc.)
and releases it through ridge and/or gable vents.
This upward air flow creates a suction that pulls
the conditioned air up and out of your home. |
|
Using Spray Foam to Convert attics into a
semi-conditioned space in hot climates by closing
soffits, gable and ridge vents is a positive design
approach in reducing the moisture loads in houses
and buildings. This can be achieved by moving the
insulation from the floor of the attic and applying
Open-Cell spray foam directly to the underside of
the roof deck to seal all the vents (preferred
method).
|
|
This design prevents the moisture laden outside air
from entering the attic and subsequently into the
living area of houses and buildings. The air seal
also prevents the radiant heat from migrating into
the living area. Lower humidity levels create indoor
air quality that is much more comfortable to live
in. |

Basements -
In below grade spaces, the importance of thermal
insulation takes a back seat to water vapor and
moisture penetration. If the basement is unfinished,
we can apply a flash coat of closed cell foam
directly to masonry walls (block or poured
concrete). |
|
Condensation often forms when warm air comes into
contact with the cool masonry wall. This is why
basements feel damp. The foam acts as a complete
moisture and vapor barrier that keeps warm air away
from cool concrete and masonry surfaces. The result
is drier, warmer basements. |
|
|
Crawl Spaces -
Cold floors over top of a vented crawl space is a
common problem. Many floors over crawl spaces have
no insulation while others have some fiberglass
batts that often are sagging, degraded and/or damp
and even moldy from condensation as a result of cold
air contacting the warmer sub-floor. |
|
In either case, cold damp air enters the living
space above through the poor insulation, cracks and
voids not covered by the the insulation. In the
summertime, cold air-conditioned air can easily
escape through these same cracks, voids and
crevices. |
|
By applying closed-cell foam directly to the ceiling
of the crawlspace, we can effectively seal every
crack, void and crevice thus reducing harmful
crawlspace air from entering the living space above.
The foam also greatly increases the structural
integrity of the floor above and eliminates the
creaking commonly found in many older homes. |
|
|
Walls -
In new construction, walls can easily be sprayed
with open or closed-cell foam to increase structural
integrity (up to 300%), reduce drafts and complete
the "building envelope". This application can
eliminate drafts that rob heat through electrical,
mechanical and plumbing penetrations in the framing. |
|
In existing homes where walls are finished (drywall
or plaster covers walls cavities), the only
effective option would be a "drill-n-fill" solution
in-which we would drill small holes at the top of
the wall cavity to allow for a hose to be inserted
and fill the wall with cellulose insulation. |

Soundproofing
-
Spray polyurethane foam insulation is highly
effective as a soundproofing material. It can be
applied in ceilings separating different floors in
the home, in bathroom walls, music studios, band
rooms, ceiling of a garage with a living space above
it, etc. |
|
|
Garage Ceilings -
Many homes are built with little or no insulation in
garage ceilings. This is especially troublesome if
there is living space (apartment, home office,
bedrooms, etc.) located above the garage. if the
ceiling is not finished, we recommend spraying foam
directly to the ceiling of the garage. |
|
This will eliminate harmful exhaust and other
outdoor polutants (as well as moisture) from
escaping up through ceiling and into the conditioned
space above. This also will create warmer floors
(winter), fewer drafts and much more efficient
heating and cooling of the space above. |
