Kingspan GreenGuard GG40-LG XPS Insulation Board 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. Kingspan GreenGuard GG40-LG XPS 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. 48 Boards Per Pallet 1536 Sq Ft Per Pallet Features & Properties R-value of 5.0 per inch of thickness Retains insulating properties over time GWP of less than 50 Maintains integrity Lightweight, durable...easy to use Continuous Insulation (Ci) for walls Insulates foundation exteriors and protects against backfill damage Property Test Method Result Nominal Thickness 2 / 3 / 4 Nominal Board Width (ft)Nominal Board Length (ft) 2 / 4 8 Edge Profile Square Channeled Property Type ASTM C 578 VI Compressive Strength, Min.
