EnergyGuard™ NH Barrier Polyiso Insulation

A TCPP-Free EnergyGuard™ NH Barrier Polyiso Insulation board is made of coated glass-fiber bonded to a core of isocyanurate foam and achieves an ANSI UL 790 roof rating over combustible wood decks with a ½” board thickness without the use of halogenated flame retardants.

EnergyGuard™ NH Barrier Polyiso Insulation maintains the same R-value when tested according to ASTM C1289 standard using the C518 test method at both a mean temperature of 40°F (4.4°C) and 75°F (24°C) and is better for the environment.
