Products / CertainTeed Flintlastic GTA-FR

Fire-resistant version of CertainTeed's Flintlastic GTA torch-applied, APP-modified bitumen cap sheet, with polyester reinforcement, for projects that require a Class A fire rating in torch-applied low-slope roof systems. CertainTeed's own product page describes it as supporting "Class A fire rated low-slope roof systems" without naming a specific fire-test standard for the product, so no fire_rating enum is set here. Meets ASTM D6222 Grade G, Type I. Standard asphaltic membrane warranties run ten to twenty-five years depending on system specification and product selection, through Limited Warranty on Materials, Integrity Roof System, or Integrity Roof System No Dollar Limit coverage.
