Elevate ISOGARD GL Polyiso Roof Insulation Board (2 in., 4 ft. x 4 ft.)

Elevate ISOGARD GL is a rigid polyiso roof insulation board with glass-reinforced mat facers on both sides for durable commercial roofing performance. Its closed-cell foam core delivers strong thermal resistance (R-11.4) in a compact 4 ft. x 4 ft. sheet.


Key Features:

  • High Thermal Performance: R-11.4 polyiso core helps reduce heat transfer through the roof assembly.
  • Durable Dual Facers: Glass-reinforced mat facer on both sides supports jobsite toughness and secure attachment.
  • Commercial Roofing Ready: Designed for flat (and tapered systems) to support thermal performance in roof applications.
  • Flexible Attachment Options: Can be installed with hot asphalt, low-rise foam adhesive, or mechanical fastening (per assembly requirements).
  • Ozone-Depletion Free Blowing Agent: Uses HCFC-free blowing agent that is ODP-free (does not deplete the ozone layer).
