TPO membranes, or Thermoplastic Olefin membranes, are single-ply roofing materials made from a blend of polypropylene and ethylene-propylene rubber. They are known for their durability, energy efficiency, and resistance to UV rays, making them a popular choice for commercial roofing applications. TPO membranes are typically white, reflecting sunlight and helping to reduce cooling costs. Installation of TPO membranes is straightforward, as they can be mechanically attached, fully adhered, or ballasted. Their flexibility allows them to accommodate building movement, while their heat-welded seams provide a strong, watertight bond. Overall, TPO membranes offer a reliable and cost-effective roofing solution.
