EnergyGuard™ Ultra Polyiso Insulation

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

  • Meets the requirements of ASTM D3273 for resistance to growth of mold.
  • Offers an alternative to a paper facer; coated glass-fiber facer reduces adhesive absorption and helps to improve nail pull strength.
  • Provides the highest R-value per inch compared to non-polyiso types of insulation of equivalent thickness.
  • Easier cutting in the field provides the installer with simplified fabricating on the roof deck.
  • Available in thicknesses ranging from 0.5" to 4.6" (12.7 mm to 116 mm).
  • For Canada approvals and Data Sheet see Product Documentation Section
