Products / Polyglass Modibond G FR

Polyglass's APP (Atactic Polypropylene, plastomeric) granulated cap sheet with fire-retardant additives for low-slope roofing, designed for heat-welded application as the outermost weathering layer of a multi-ply roof system over a compatible base or interply sheet (may also be applied directly to non-combustible substrates). Incorporates a high-quality polyester mat for tear strength and puncture resistance, with a granulated top surface and a factory-applied burn-off film on the bottom. No UL 790/ASTM E108 roof covering class is stated on the product page or data sheet despite the "FR" fire-retardant naming; fire classification is assembly-dependent.
