Flintlastic® Ultra Glass SA is a premium, self-adhered base sheet for hybrid roof systems with a torch-applied cap or cap set in hot asphalt or cold adhesive. It is suitable for use in both new construction and reroofing over a variety
of 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.

Installation

CertainTeed's Flintlastic Ultra Glass SA is self-adhered.  Flintlastic Ultra Glass SA is installed with 4" side laps and 6" end laps, with end laps diagonally staggered not less than 3' apart. Flintlastic Ultra Glass SA must be applied to a clean, non-nailable substrate by peeling off the siliconized backer that exposes a specially formulated SBS high-tack self-adhesive surface.

Rolls should be stored upright, off ground, completely protected from the weather. Roof decks shall be structurally sound, dry, and smooth and meet or exceed minimum requirements of the deck manufacturer, local code and CertainTeed.

Warranty Details

CertainTeed backs its commercial roofing systems with the confidence of four warranty choices:

  • Limited Warranty on Materials
  • Limited Warranty on Systems
  • No Dollar Limit (NDL) Limited Warranty
  • Full System NDL Limited Warranty

Owners and specifiers who choose the NDL or Full System NDL warranty options have the added security of manufacturer involvement in the sometimes difficult process of contractor qualifying and workmanship inspection. Consult with the roofing contractor and your CertainTeed commercial roofing territory manager to decide which CertainTeed warranty is best for your building or project.
