Insulfoam has developed a composite insulation panel for new or retrofit roof systems requiring resistance to misuse, abuse and severe weather. The new InsulFoam® HD Composite panel is a closed-cell, extremely lightweight and resilient EPS foam factory bonded to high-density polyisocyanurate cover board. It is widely compatible with a range of roofing membranes – including EPDM (M-class rubber), TPO (thermoplastic polyolefin), PVC (polyvinyl chloride), CSPE (chlorosulfonated polyethylene), and low-sloped, built-up and modified bitumen membrane systems – it is also a suitable insulation underlayment for metal roofing.
