Flintlastic® Ultra Glass SA is CertainTeed’s unique, most robust, self-adhering base or interply for hybrid roof systems with a non-self-adhered cap sheet. This 120 mil membrane is manufactured with a heavy duty fiberglass reinforcement saturated and coated with SBS-modified bitumen, offering exceptional durability. Flintlastic® Ultra Glass SA is suitable for use in both new construction and reroofing and may be directly adhered to approved substrates, including but not limited to insulation, concrete, and plywood/OSB. Flintlastic® Ultra Glass SA delivers measurable labor savings over traditional fully adhered asphaltic membranes without compromising waterproofing protection. This versatile base ply can be used in CertainTeed two-ply, low-slope roofing systems for up to 31 1/4 - year warranty durations for Credentialed Contractors. Reach out to your local CertainTeed Territory Manager to request a sample and demonstration of Flintlastic® Ultra Glass SA.
