Insulation
GreenGuard Insulation Board’s extruded polystyrene (XPS) construction provides superior moisture resistance. And since it does not absorb moisture, it retains its insulating properties over time. With an R-Value of 5.0 per inch of thickness, the board offers excellent thermal performance, increasing the energy efficiency of your structures. Plus it’s lightweight, easy to handle, and easy to cut with a knife. GreenGuard Insulation Board contains up to 30% post-industrial recycled material.
