Closed Cell Spray Foam Insulation 
For Electric & Natural Gas Customers

Closed cell spray foam insulation provides a higher R-value of 6.5 per inch, is also called two-pound foam, has a density of about 2 lb. per cubic foot and an R-value of 6 to 6.5 per inch, and is significantly more expensive than half-pound foam. Closed cell foam is heavier than open cell foam as the bubbles in the foam touch each other but are not open to each other. By not being open, the closed cell foam is a barrier to water and as such has specific applications. Closed cell foam is more expensive than open cell foam.
