New InsulFoam® HD Composite roof insulation system combines lightweight EPS with high-density polyisocyanurate for use in adverse weather
Tacoma, Wash., September 27, 2011 – Insulfoam – a leading manufacturer of expanded polystyrene (EPS) building materials – 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. The factory laminated composite insulation provides significant field labor savings, a cover board offering high compressive strength (100 psi), and high thermal efficiency that is not available with traditional foam insulation.   www.insulfoam.com

Substantially less expensive than similar Iso composite products, the lightweight InsulFoam HD Composite insulation system makes an entire fully adhered single-ply roof system more resistant to abuse. 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.

The product has a full array of UL approvals,...
