The Benefits of Spray Foam Insulation
Types of Spray Foam Insulation
There are two different types of spray foam insulation, Open Cell Spray Foam and Closed Cell Spray Foam, each with their unique benefits discussed below.
Open cell spray foam
Open cell spray foam insulation works as an insulator and air barrier. Weighing only 0.5 pounds per cubic foot, open cell spray foam gets its name from its broken cell structure, which allows air to fill the empty space inside the material. The typical R value of open cell foam is 3.7 per inch. Open cell spray foam insulation is vapor permeable, dampens sounds and eliminates air infiltration.
Closed cell spray foam
