The TPO Reinforced Membrane is a premium, heat-weldable, single-ply thermoplastic polyolefin (TPO) sheet designed for new roof construction and re-roofing applications. It uses advanced polymerization technology that combines the flexibility of ethylene-propylene (EP) rubber with the heat weldability of polypropylene. It includes OctaGuard XT™, an industry-leading, state-of-the-art weathering package which enables WeatherBond PRO TPO to withstand extreme weatherability testing intended to simulate exposure to severe climates. 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 creates a consistent, watertight monolithic roof assembly. The membrane is environmentally friendly and safe to install.
