Polyiso Foam Board Insulation with CGF Facing on Both Sides
CGF is composed of coated polymer bonded fibrous glass mats bonded with organic polymer binders
and coated with organic polymer, clay, or other inorganic substances. The coating may be applied either
to the glass fibers before bonding into mats or after the glass mats are bonded together. Glass fiber mats
are coated. This facer offers enhanced performance through superior moisture resistance.
CGF also offers increased resistance to foot traffic, hail, wind uplift, and fire.
