What is Spray Foam?

Spray foam insulation is a self-adhering, two-component product that gets sprayed on exposed walls, attic roof lines, sill plates, band joists, in exterior overhangs, and in crawl spaces. The material bonds to most construction material substrates including metal, wood, plastic, and brick and provides a rigid insulation system that adds structural strength to buildings. Close-cell spray foam insulation has the highest level of thermal resistance per inch of any commonly used insulation products.
