TPO Roofing Systems: Thermoplastic Polyolefin single-ply roofing aka TPO. This product can be fully adhered or mechanically fastened to almost all types of decking substrates, PolyIso-Insulation boards and even parapet walls through the different pre-enginnered installation specifications. Depending on the project needs the single-ply membrane is available in 50, 60, 70, or 80 mil thickness. This membrane is composed of three layers, a TPO polymer base, a polyester-reinforced fabric center and a thermoplastic polyolefin compounded top ply.
When compared to other single-ply roofing products TPO is primarily the only product that is mold resistant, non porous so dirt cannot accumulate, extremely durable against punctures and tearing and highly flexible for thermal expansion and contraction. It is also reflective and energy efficient and when coupled with the right insulation is an excellent choice to help lower electric bills.
