Firestone insulation boards ISO 95+ GL

The Firestone Polyiso insulation boards offer high-energy efficiency for which Polyisocyanurate (PIR) boards are renowned. Compatible with all types of Firestone single-ply roofing systems, this lightweight, easy-to-handle insulation is suited for direct application onto steel roof, concrete or wood deck. It provides outstanding thermal resistance and compressive strength.

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.

As part of a Firestone Total Roofing System, Firestone ISO 95+ GL demonstrates a series of features & benefits:

• Compatible with all types of single-ply roofing systems: ballasted, fully adhered and mechanically attached.
• Suited for direct application onto steel roof, concrete or wood deck.
• Outstanding thermal resistance and compressive strength.

• ISO 95+ GL boards are Factory Mutual (FM) approved.
