What is Spray Foam Insulation?

Typically made from polyurethane foam, spray foam insulation is a two-part formula that is mixed and applied as a liquid, expanding to fill any voids or gaps while adhering strongly to the application site. It offers an R-value of up to 7.0 per inch, making it one of the most effective insulation products on the market.

Best Places to Install Spray Foam Insulation

With its superior insulation, air sealing qualities and water-resistance, spray foam is excellent for nearly any area of the home, including:

Spray foam offers excellent performance that outshines many competing products, including fiberglass and cellulose insulation.

How Spray Foam Compares to Other Insulation Types

The main competitors to spray foam are fiberglass and cellulose. Fiberglass batts are easier to install than spray foam and a bit less expensive, but they only offer an R-value of about 4.3 per inch compared to the 7.0 per inch of spray foam.

Like spray foam, cellulose can be installed in finished walls with special equipment, but it only has an R-value of about 4.0 per inch, far less than spray foam’s 7.0 per inch. Radiant barriers offer great protection against radiated heat in the attic, but they offer minimal protection against conducted heat, unlike spray foam. Combined, spray foam and radiant barriers could be an excellent way to keep attic temperatures and roof damage to a minimum.
