HD Composite Roof Insulation Panels
HD Composite panels combine closed-cell EPS foam with high-density polyisocyanurate cover board for high resistance to abuse in single-ply roof systems. The factory-laminated insulation offers 100 psi compressive strength and high thermal efficiency.
The panels can serve as an insulation underlayment for metal roofing and are also compatible with many roofing membranes, including EPDM (M-class rubber), TPO, PVC, CSPE, and low-sloped, built-up, and modified bitumen systems. HD Composite panels are available in 4-foot by 8-foot panels with thicknesses from 1.5 inches to 7 inches.
