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.
Benefits of EnergyGuard™ Barrier Polyiso Insulation include:
High Insulation Value - provides the highest R-value per inch compared to any other type of insulation of equivalent thickness
Meets the requirements of ASTM D3273 for resistance to mold growth
Excellent dimensional stability
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
