      Why EnergyGuard Polyiso Insulation?

      EnergyGuard™ Polyiso Insulation is made of glass fiber-reinforced cellulosic felt facers bonded to a core of polyisocyanurate foam. 


      Benefits of EnergyGuard Polyiso Insulation include:
      • Excellent “LTTR” value compared to any other FM Class 1 rated products of equivalent thickness.
      • FM approved, subject to the conditions of approval as a roof insulation when installed as shown in the current edition of the Factory Mutual Research Approvals Guide. FM Approved — consult for specific assemblies.
      • Lighter than most other insulating products offering comparable thermal resistance; as much as five times lighter in weight than many other materials with the same R-value.
      • Excellent dimensional stability.
      • Lower overall perm rating than many conventional insulation boards.
      • High moisture resistance and no capillarity; is stable and maintains its physical and insulating characteristics.
      • Because of its light weight, this material is easier to handle on the job site and installs faster.
      • Easier cutting in the field provides the installer with simplified fabricating on the roof deck, which minimizes on-the-job damage.

      Refer to the application specifications in the current membrane manufacturer’s application and specifications manual for proper installation procedures.
