TPO Membranes, what are they, is it rubber?
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.
Thermoplastic Roofing: PVC vs. TPO
What is thermoplastic?
Thermoplastic refers to a synthetic substance that is softened when heated, but hardens upon cooling. Thermoplastic roofing membranes are single-ply and can be installed using a variety of methods including mechanical attachment, point-affixed and fully adhered.
TPO and PVC roof systems
Versatile, customizable, energy efficient.
The PVC roofing membrane has an extensive installation history in the roofing industry. First installed in the early 1960’s, PVC was the industry’s answer to the oil crisis, as it was the first membrane to contain half of the fossil fuels normally used in system manufacturing.
Engineers discovered that adding additional solid plasticizers to the PVC membrane allowed for additional weatherability and flexibility, where the membrane alone would be more susceptible to seasonal climate changes. PVC membranes are incredibly versatile and chemical resistant. They are available in a variety of colors, thicknesses, widths, and reinforcements, making them an excellent option for almost any roofing project. PVC roofing is highly recommended for roof-over projects.
Along with the environmental benefit of using (fewer) fossil fuels in the manufacturing process, PVC is highly reflective/UV resistant, making the membrane an energy efficient option for warmer climates.
Thermoplastic Polyolefin (TPO) History and Benefits
Cost-effective, recyclable, ENERGY STAR rated.
TPO roof systems have been installed in the U.S. for the last 30 years. TPO membranes are made with a co-polymerized rubber that allows them greater flexibility in cold climates.This membrane is best recognized for having the benefits of EPDM and PVC systems, at a more economical cost. TPO membranes are white and highly-reflective, making them an excellent choice for those looking to reduce energy costs. In addition to being ENERGY STAR rated, TPO’s recyclability makes it an excellent choice for the environmentally conscious.
