As part of a Firestone total roofing system, ISO 95+ GL insulation boards provide you with a single source of quality design, superior materials and warranty responsibility.
Before insulation is placed on the roof deck, the substrate must be clean, dry, free of debris, water, ice or snow and suitably prepared by removing all defects that might affect the quality of the application. Any unusual deck conditions or defects should be brought to the architect or building owner’s attention prior to installation.
ISO 95+ GL insulation boards must be installed using fasteners and plates, hot bitumen or Firestone-approved insulation adhesives. Insulation shall be neatly fitted to all roof perimeters, penetrations and abutments. The ISO 95+ GL board is suitable for adhered, ballasted and mechanically fastened single-ply roofing systems.
