Wayne, N.J.-based GAF announced the production of high-density polyisocyanurate (ISO) cover boards, which can be used as a protective layer over boardstock insulation or as a recover over an existing roofing system.
“Our new GAF High Density Cover Board is a key component for a more resilient roofing system from single ply to asphaltic,” said Justin Hardy, GAF product manager at GAF. “The ability to protect a roof from traffic and impact while adding R-value performance is a game changer.”
These cover boards offer superior roof protection from foot traffic, storms and hail, while also offering the benefit of being easy to install due to their light weight.
GAF offers two versions: HD with more than 80 psi, and HD PLUS with more than 110 psi compressive strength and a durable coated glass facer. Each of these boards is an ideal choice for protecting your roof from the elements and rooftop traffic. GAF EnergyGuard. HD is a 1/2-in. thick high-density ISO cover board with an R-value of 2.5, the highest of any cover board -- and, at 11 lbs.(HD) 13 lbs.(HD PLUS) per 4-ft. by 8-ft. board, it’s a fraction of the weight of gypsum cover boards.
Aside from its high R-value, which contributes additional energy savings to the roofing system and the building, GAF has the ability to ship three times more product on one truck than gypsum cover boards. Using fewer trucks means less carbon emissions, with the added benefit of taking less time to unload at the jobsite.
