TPO (Thermoplastic Polyolefin)
TPO roofing membranes do not contain organic material.
These roofs consist of a single ply of TPO roofing membrane. TPO is classified as a weldable thermoplastic, meaning it can be hot-air welded. TPO roofing and PVC roofing are not compatible for welding with each other. Some roof system manufacturers report that the welded seam of their membranes are stronger than the membrane itself. Often, these materials are mixed with other compounds to enhance the material’s properties such as fire and UV radiation resistance. Although available in a variety of colors, TPO roofing is sometimes called ‘white roofing’ or ‘cool roofing’.
The resulting white roof system, if clean, is highly emissive and reflective of solar heat and radiation compared to dark roof surfaces.
TPO is available in non-reinforced and reinforced formats – reinforcement is either of polyester or fiberglass scrim fabric. TPO is typically applied as a fully adhered or mechanically fastened system and the material remains weldable throughout its service life.
