TPO (thermoplastic Polyolefin) single-ply roofing Systems incorporate 45-mil, 60-mil, 72-mil or 80-mil (TPO) Thermoplastic Polyolefin membrane. TPO Membrane is comprised of three layers – a TPO polymer base; a strong, polyester-reinforced fabric center (scrim) and a tough thermoplastic polyolefin compounded top ply. The smooth surface resists dirt pick-up and biological growth compared to other thermoplastic membranes. TPO membranes carry the ENERGY STAR ® rating having exceeded the stringent program guidelines based upon solar reflectance and heat emittance. ENERGY STAR compliant TPO membranes with their high reflectivity ratings help reduce the amount of energy required to maintain cool building environments.
