About EnergyGuard™ Ultra Tapered Polyiso Insulation

EnergyGuard Ultra 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. EnergyGuard Ultra Tapered's CGF facer is moisture resistant, resistance to mold and more durable than the GRF facers.
