Closed-cell foam is an all-in-one insulation and air sealing system. Closed-cell foam insulation is designed to solve your extreme insulation requirements. It’s ideal for whole-house applications and is supported by Building Science professionals.
What Is It?
Two-pound foam, also known as closed-cell foam, has a density of about 2 lb. per cubic foot and an R-value of approximately 6.5 per inch. Closed-cell foam is a vapor barrier at about 1.0-1.5 inches and has a permeance of .8 perm.
WHY CLOSED-CELL INSULATION?
Due to its high R-value, it’s able to minimize hot and cold spots to improve efficiency
Reduces the risk of moisture intrusion in the wall cavity
