Product Feature: Durable, Energy-Efficient Composite Insulation

HD Composite

InsulFoam HD Composite

InsulFoam HD Composite roof insulation system combines lightweight EPS with high-density polyisocyanurate for use in adverse weather.


Our composite insulation panel is ideal for new or retrofit roof systems requiring resistance to misuse, abuse and sever weather.  The 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.

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), TP (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, and is available in standard 4′ x 8′ panels, with thicknesses ranging from 1.5″ to 7″.  We also produce custom lengths and widths with little or no impact on lead time.

“InsulFoam HD Composite insulation brings together the best features of two leading roof insulation materials for an extremely competitive price.  The R-values of the EPS remain stable over time for exceptional long-term insulation, and the polyiso caps that off with additional insulation and a protective layer.  The product is substantially more lightweight than gypsum and OSB for fast install, while standing up to abuse.  It provides long-lasting, energy-efficient roof insulation in a range of harsh climates.”  – John Cambruzzi, Regional Sales Director
