What is TPO Roofing?
Thermoplastic Polyolefin (TPO) is a single-ply reflective roofing membrane made from polyprophylene and ethylene-propylene rubber polymerized together. It is typically installed in a fully adhered or mechanically attached system, allowing the white membrane to remain exposed throughout the life of the roof. The first sheet of TPO roofing membrane was installed in 1989 and since then millions of square meters of TPO has been installed worldwide.
TPO roofing membranes are highly attractive in regions with more cooling degree days – when cooling equipment is used – than heating degree days. TPO membranes reflect UV radiation keeping the surface of the roof and the building cool during summer months. This helps reduce cooling costs, and also decreases the amount of carbon emissions.
TPO is highly resistant to tears, impacts, and punctures yet remains flexible to allow for building movement – it is available in 3 different thicknesses, 0.045”, 0.060”, and 0.080”. TPO can be installed on low and high slope surfaces and can be heated and reshaped multiple times, which is particularly helpful when completing roof details.
