Parsippany, New Jersey – GAF has introduced a new non-halogen flame retarded polyisocyanurate insulation designated EnergyGuard NH Polyiso.
The company claims that this makes it the first roofing manufacturer to offer a full line of Red List free roofing assemblies across its product range.
The board retains the inherent properties and performance factors of standard polyiso insulation, including a UL Class A roofing fire rating and a very high insulation value. However, it contains no halogenated flame retardants.
The company has replaced TCPP flame retardant with a non-halogenated material with the same flame-retardant properties, in recognition of the growing number of jurisdictions where legislation restricting flame retardant use has been introduced. The new board has a Declare label that designates it Red List free.
The boards are made from glass-reinforced cellulosic felt or coated glass facer, bonded to a core of non-halogenated isocyanurate foam. It attains a Class A roofing fire rating, despite the absence of halogenated flame retardants, and no ozone-depleting blowing agents are used in its manufacture, said the firm.
“There is increasing interest in Red List Free products,” said Jeanine Mulcahy, GAF’s product manager for insulation and fastener systems. “The development of EnergyGuard NH Polyiso insulation board is one more indication that architects and contractors who share our commitment to sustainable design can count on GAF for environmentally preferable products.”
