What are some of the advantages to Polyurethane Spray Foam Insulation?

THE BUILDING ENVELOPE Spray foam insulation provides a complete, seamless building envelope. A building envelope provides protection against air, moisture, heat and cold. The seamless material virtually eliminates energy-wasting air filtration VAPOR RETARDER Spray foam insulation prevents condensation of water vapor inside wall or ceiling materials. When moisture is trapped it can cause damage to the wallboard and paint as well as structural deterioration. AIR BARRIER Spray foam insulation act as an air barrier, spray foam insulation provides insulation and air sealing in one step. This prevents outside air from coming in and inside air from moving out. Air leakage can also introduce moisture into the cavity, resulting in wet insulation and mold. Spray foam insulation prevents air leakage. HIGHEST R VALUE Spray foam insulation has the highest R-value per inch. The higher the R-value the greater the insulating power. Spray foam insulation allows for more insulation in a tighter space ...  more
