Spray Foam Insulation

What Is Spray Foam Insulation?

Spray foam is a wet insulation which can be installed on floors, ceiling cavities, walls, spaces around electrical outlets and light fixtures, and gaps between walls, windows or doors. This type of insulation is offered in two different varieties: open cell and closed cell. Each variety of spray foam is designed to meet different insulation needs and purposes, providing versatility in the use of the product.

Types Of Spray Foam Insulation

Open Cell Spray Foam has an R-value of around R-3.8 per inch, expanding to about 3 inches of thickness. When this type of foam is sprayed, bubbles inside burst, leaving behind small pockets of air. Water is able to flow through the foam, which prevents mold, while also not absorbing any moisture or losing any insulating performance. Open cell spray foam is also used to muffle sound.

Closed Cell Spray Foam has an R-value of approximately R-7 per inch and expands to about 1 inch thickness. The air bubbles in closed cell foam do not rupture, which create closed air pockets and a vapor barrier. Water is unable to move through or be absorbed into closed cell foam, which also blocks mold and mildew. Closed cell foam is dense and strong, and can be left exposed after an install. This type of insulation is beneficial in flood zones, as the material repels water and creates an air seal.
