About EnergyGuard™ Barrier Polyiso Insulation

EnergyGuard™ Barrier Polyiso Insulation is made of coated glass-fiber bonded to a core of isocyanurate foam and achieves an ANSI UL790 roof rating over combustible wood decks with a ½" board thickness.

  • Lower overall perm rating than many conventional insulation boards
  • 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
