      Why EnergyGuard NH Tapered Polyiso Roof Insulation?

      EnergyGuard™ NH Tapered Polyiso Roof 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 as it contains no potentially hazardous flame retardent chemicals. EnergyGuard™ NH Tapered Polyiso Insulation systems are a series of tapered and fill panels that, when properly installed on a low-slope roof, help drive water to the drain, thus prolonging the life of your roof system. Available in 1/16”, 1/8”, 3/16”, 1/4”, 3/8”, and 1/2” per foot slope, in both standard and extended panels.
