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.
Cooling Degree Days
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.
Reflectivity & Sustainability
Many companies and organizations are thrilled with the environmental benefits of TPO membranes. The Earth Rangers Centre (ERC) in Woodbridge, Ontario installed an UltraPly™ TPO roof on their office building, which is currently one of the most energy efficient buildings in Canada. Operating at less than 9kWh per square foot, and using nearly 90% less energy than other buildings of its size, TPO provided the reflective roof that works in conjunction with skylights and solar panels that helped ERC reach that impressive level of sustainability.
TPO is the fastest growing commercial roofing membrane on the market today, having grown from 23% to 41% in the U.S. in seven years, as of 2013.
Since the installation of the first TPO roofs in the early nineties, hundreds of millions of square meters of UltraPly TPO roofing membranes have been successfully installed worldwide.
TPO is 100% recyclable
Benefits of UltraPly™ TPO
Durability, Flexibility and Versatility – UltraPly 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.
Economical and Easy to Install – UltraPly TPO’s flexibility allows for a rapid installation and requires little maintenance throughout its life. TPO membranes are commonly fully adhered or mechanically attached to the underlying insulation or cover board. Firestone UltraPly TPO membranes are available in rolls ranging from 5’ x 100’ to 12.4’ x 200 which reduce number of seams and cut labour costs drastically.
Cool Roofing Matters – A light coloured roof that reflects the sun’s energy can play a significant role in reducing the buildings cooling costs. It also offers benefits to the surrounding environment through a reduction of the urban heat island (UHI) effect.
Welded Seams for Long-Lasting Performance – TPO membranes are heat-welded at 926ºC with a hot-air gun. The result is a fused seam that’s stronger than the field of the membrane.
Sustainable and Environmentally Friendly – TPO membranes contain no toxic or hazardous ingredients and are fully recyclable.
