GAF

GAF has introduced its EnergyGuard™ 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. These new boards offer excellent roof protection from foot traffic, storms and hail, and are 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. GAF EnergyGuard™ HD is a half-inch thick, high-density ISO cover board with an R-value of 2.5, the highest of any cover board. For more information, visit www.gaf.com.
