As far as insulation values and air sealing, spray foam and injection foam are the best processes available. Spray foam insulation provides a higher insulation value than any other commonly used product, helps air seal your home, creates a healthier living environment, is environmentally friendly, and can help reduce new construction and existing homes’ heating bills by more than half. 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. Closed-cell spray foam also has nearly zero air permeability and acts as a vapor barrier. Because the product is sprayed onto the substrate and expands to nearly 30 times its original volume, it conforms to many irregular spaces and fills voids that other insulation materials leave open. It requires no fasteners and is typically installed in a single application. Home Owner-Benefits:
