CertainTeed Flintglas MS Cap Sheet is a roll roofing product designed for use as a cap sheet over inorganic and organic built-up roofing systems. It may also be used as a heavy-duty, venting type base sheet when installed mineral side down and either mechanically fastened or spot mopped over lightweight insulating concrete decks or existing smooth surfaced membranes. It is surfaced with ceramic granules to provide a durable, heat reflective weathering surface when used as a cap sheet.
CertainTeed Flintglas MS Cap Sheet is manufactured on a durable, high quality fiber glass mat which receives a heavy coating of weathering grade asphalt and is surfaced with ceramic granules. The fiber glass base mat provides excellent strength and moisture resistance in conjunction with a reflective, durable granule surface.
CertainTeed Flintglas MS Cap Sheet may be applied in either hot asphalt or approved cold adhesive such as CertainTeed's FlintBond. Rolls should be stored upright, off ground, completely protected from the weather. Roof decks shall be structurally sound, dry, smooth and meet or exceed minimum requirements of the deck manufacturer, local code and CertainTeed. Roof decks shall provide positive drainage.
