Thermoplastic Polyolefin Roofing System

Thermoplastic polyolefin tpo roofing systems.

Thermoplastic polyolefin roofing system. Thermoplastic polyolefin is a single ply roofing membrane that is one of the fastest growing commercial roofing systems on the market. Tpo membranes are white and highly reflective making them an excellent choice for those looking to reduce energy costs. A quality thermoplastic polyolefin tpo roof system will offer many benefits including cool roof properties that help reduce the load on hvac equipment reduce temperatures in interior unconditioned spaces and a robust weathering package that can withstand over 60 days at 275 degrees fahrenheit without cracking or showing signs of material failure. Tpo membranes are manufactured in sheets that are 10 12 or 20 feet wide.

The first sheets for membrane roofing were introduced in 1989. This membrane is composed of three layers. A thin white membrane known as thermoplastic polyolefin or tpo is an ideal roofing solution for energy efficiency. Heat welded seams provide superior strength.

Thermoplastic polyolefin compounded top ply. Tpo membranes are made with a co polymerized rubber that allows them greater flexibility in cold climates. Tpo s long term heat uv and natural fungal resistance plus flexibility without need for plasticizers also make tpo a reliable low slope roofing system. Tpo roofing systems are made up of a single layer of synthetics and reinforcing scrim that can be used to cover flat roofs.

To understand why tpo membranes are the fastest growing segment of the membrane market a little background is in order. Polyester reinforced fabric center scrim. Short for thermoplastic polyolefin tpo is a single ply roofing membrane that offers excellent performance at a cost effective price. Tpo based products have been available since the 1980s.

In the building trades the acronym tpo stands for thermoplastic polyolefin a material originally developed for pond liners and used extensively for roofing since 1989. It s a single ply membrane made from a polymerized combination of polypropylene and ethylene propylene rubber that can be attached to a roof with adhesive or with mechanical fasteners. By 1993 the earlier non reinforced membranes were replaced by fabric reinforced sheets the version available today. The seams intersections and other roof patches are applied through heat welding rather than using adhesives.

Tpo is highly reflective delivers great ultra violet resistance and is available in several color options. Tpo roofing systems thermoplastic polyolefin tpo single ply roofing membranes are among the fastest growing commercial roofing products and have gained praise across the industry for their many performance and installation advantages.
