- Applied as a liquid, spray foam insulation expands to 100 times its volume in seconds to fill every crack and crevice.
- Spray foam insulation remains flexible and after installation the integrity of the building envelope seal remains intact over time.
- Spray foam insulation acts as a complete insulation and air barrier to minimize air leakage and seal the building envelope for optimal airtightness.
- Homeowners may choose to use spray foam throughout their entire home and, in many cases, spray foam insulation is also used for air sealing. This is a perfect solution to keep conditioned air in the home since spray foam insulation easily expands to fill penetrations where conditioned air can escape.
OPEN CELL SPRAY FOAM
Open cell spray foam is soft. The walls (or cells) of the bubbles are broken and air fills these spaces. This makes the foam soft and pliable, similar to a rubber ball. The R-value of the insulation is related to the value of the air inside these broken bubbles. Open cell insulation density is up to one pound per cubic foot.
CLOSED CELL SPRAY FOAM
Closed cell spray foam is solid because the cells of the bubbles remain intact, making the product rigid. The cells are filled with a gas that makes the R-value higher than open cell foam. Closed cell foam has varying degrees of hardness depending on its density, but is typically 1.5 pounds to 4 pounds per cubic foot.
