Versicos TPO reinforced membrane is a premium, heat-weldable, single-ply thermoplastic polyolefin (TPO) sheet designed for new and retrofit low-slope roofing applications. TPO membranes can be mechanically fastened or fully adhered as part of a complete roofing assembly. Versico TPO membranes use advanced polymerization technology that combines the flexibility of ethylenepropylene (EP) rubber with the heat weldability of polypropylene. All Versico TPO membranes include OctaGuard XT™, an industry-leading, state-of-the-art weathering package. OctaGuard XT technology enables Versico TPO to withstand the 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 results in consistent, watertight, monolithic roof assembly
