Henry TPO Membrane uses advanced polymerization technology that combines the flexibility of ethylene-propylene (EP) rubber with the heat weldability of polypropylene. Our TPO Membrane contains an industry-leading, state-of-the-art weathering package. This technology enables the TPO Membrane to withstand the extreme weatherability testing that is intended to simulate exposure to severe climates.

Physical properties of TPO 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 smooth surface texture of the TPO Membrane reduces dirt pick-up when exposed to rooftop conditions. TPO Membrane is environmentally friendly and safe to install.
