Firestone ISO 95+ Polyiso Insulation offers high-energy efficiency through the highest R-value ratings per inch versus other insulation materials and is compatible with all types of commercial roofing systems. The lightweight, easy-to-handle insulation is especially suited for direct application on FM approved and UL classified steel roof deck assemblies. Standard flat ISO 95+ is available in board sizes of 4’ x 4’ and 4’ x 8’ and in thicknesses from 1” to 4”.
Firestone ISO 300 offers a closed-cell polyiso foam core laminated to a polymer coated glass-fiber mat facer that is moisture resistant. ISO 300 was originally designed for cold-applied modified bitumen roofing systems, because it maximizes coverage rates of adhesives and achieves enhanced code approvals for some assemblies. ISO 300 can be used with all Firestone Roofing Systems.
