Thermoplastic Polyolefin (TPO) is a single-ply roofing membrane composed of polypropylene and ethylene-propylene rubber polymerized together. It can be mechanically attached or fully adhered and offers many of the same benefits as PVC roofing, at a lower price point. Introduced 20 years ago, it has an estimated lifespan of 10-20 years.
TPO is available in wide widths, cutting down on installation time and reducing the number of seams required. This creates a smooth surface that resists dirt and debris build up. TPO’s reflective properties help it meet and often exceed ENERGY STAR requirements which translates into impressive energy savings for building owners.
TPO is resistant to dirt, bacteria, mold, UV rays, chemicals, fire, and extreme weather. Its flexible membrane means it is not easily punctured or torn and can accommodate structural shifts due to settling and temperature fluctuations. When applied using heat welding at the seams it is practically impermeable.
TPO’s reflective white surface reduces energy waste by reflecting more than 70% of solar heat, keeping the building it covers substantially cooler. This greatly reduces energy waste and the heat island effect often found in commercial areas. TPO is also 100% recyclable at the end of its life.
TPO starts at one of the lowest price points for energy efficient commercial roofing materials. Its light weight and wide width sheets also help owners save on installation costs. Its reflectivity and the cumulative utility savings owners can expect over its lifetime further add to TPO’s value.
