Spray Foam Insulation

Spray foam insulation is a material that creates an air seal in any open cavities where it’s applied.

Spray foam can be used in attics, crawl spaces, rim joists, new build construction, pole barns, and commercial buildings. Unlike injection foam that is used in enclosed cavities, spray foam is better suited for open cavities.


What is the Difference Between RetroFoam Injection Foam and Spray Foam Insulation?

Spray foam and injection foam insulation are more similar than they are different.

Both materials create an air seal and work to make homes more comfortable and energy-efficient. The difference really comes down to how they are installed and their composition.

Spray foam insulation is best suited for open cavities, like attics, crawl spaces, rim joists, and exposed wall cavities. Injection foam is made specifically for existing enclosed wall cavities.
