carlisle syntec systems logoFor flat, or smooth roof applications B&B Roofing and Exteriors installs Carlisle’s Sure-Weld TPO reinforced membrane, which  is a premium, heat-weldable, single-ply thermoplastic polyolefin (TPO) sheet designed for new roof construction and re-roofing applications.  Physical properties of the membrane are enhanced by a strong polyester fabric that is encapsulated between the TPO-based top and bottom plies.  The combination of the fabric and TPO plies provides high breaking and tearing strength, as well as excellent puncture resistance. The relatively smooth surface of the membrane produces a total surface fusion weld that results in a consistent, watertight, monolithic roof assembly.  The membrane is environmentally friendly and safe to install.
