For use as General Purpose Insulation for Roofing, Wall and Foundation Applications Requiring 40 psi Minimum Compressive Strength
GreenGuard extruded polystyrene (XPS) does not absorb moisture and retains its insulating properties over time, making it an ideal exterior insulation. With an R-Value of 5.0 per inch of thickness, the board increases the energy efficiency of your structures. Plus, it’s light weight, easy to handle, and easy to cut with a knife. GreenGuard Type VI 40 psi Insulation Board is designed for use in high load applications requiring compressive strength up to 40 psi. It meets ASTM C 578 Type VI requirements.
