ISO 95+ GL

Firestone ISO 95+ GL consists of a closed-cell Polyisocyanurate foam core laminated on both sides to a black glass reinforced mat facer of approx. 150 g/m². Firestone foam technology incorporates a HCFC-free blowing agent that does not contribute to the depletion of the earth’s ozone layer (ODP-free). Firestone ISO 95+ GL contains between 29 and 52% recycled material, depending on the thickness of the board.
