What Is Spray Foam Insulation?

Spray foam insulation insulates and seals air leaks in one application. Spray foam insulation is comprised of two products that react when combined. This reaction causes the foam to expand and, when installed, fill cracks and crevices. Spray foam insulation also dampens sound transfer and deters mold growth.

There are two types of spray foam insulation – open cell spray foam insulation and closed cell spray foam insulation. Open cell spray foam is lighter in weight than closed cell spray foam and is flexible. Closed cell spray foam insulation is heavier and more dense than open cell spray foam. Closed cell spray foam has a higher R-value than open cell spray foam and is more resistant to moisture. It is frequently installed in areas such as crawl spaces where there is higher moisture composition.
