The Sure-Weld Reinforced TPO Membrane is a heat-weldable, premium, single-ply thermoplastic polyolefin (TPO) sheet designed for new roof construction and re-roofing applications. It is formulated with additional flame retardant for higher-slope fire code approvals. Sure-Weld EXTRA is thick for significantly higher strength and weatherability.
The membrane is environmentally friendly and safe to install. 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.
All Sure-Weld TPO membranes include OctaGuard XT™, an industry-leading, state-of-the-art weathering package. OctaGuard XT technology enables Sure-Weld TPO to withstand the extreme weatherability testing that is intended to simulate exposure to severe climates.
