      Why EnergyGuard Tapered Polyiso Foam Insulation?

      EnergyGuard™ Tapered Polyiso Insulation provides a logical and economical answer for roofs that do not permit adequate positive drainage, like low-slope roofs.

      When correctly installed, tapered insulation helps eliminate problems due to ponding water and can extend the longevity of your low-slope roofing system. It is readily available in the two most popular and efficient tapers, 1/8" (3.18 mm) per foot (305 mm) (1%) and 1/4" (6.35 mm) per foot (3.18 mm) (2%).

      • Properly designed and installed, EnergyGuard™ Tapered Polyiso Insulation Systems virtually eliminate ponding water
      • High thermal efficiency
      • Easily installed with mechanical fasteners, hot asphalt, or loose-laid in a ballasted system
      • Low point and letter codes are designated on each board
      • Engineering design board layouts are available from your plans and field verified dimensions
