CertainTeed is adding a new heavy-duty base sheet for modified bitumen roofing systems that boasts superior performance in an easy-to-install, time-saving design. Featuring a durable, self-adhering sheet with a sanded top surface, the new Flintlastic Ultra Glass SA Base Sheet is ideal for use in two-ply, 20-year commercial roofing systems.
Suitable for use in new construction or re-roofing over a variety of substrates, the Flintlastic Ultra Glass SA Base Sheet offers the high-tack characteristics and pliability that contribute to a smoother, more uniform application without the need for adhesives or hot asphalt.
The Flintlastic Ultra Glass SA Base Sheet is flexible and designed to meet a wide variety of performance requirements. When used as a first ply over a non-nailable or an insulated substrate, the base sheet provides excellent moisture resistance. The base sheet can also serve as a vapor retarder when installed under roof insulation.
