TPO (thermoplastic olefin) ROOF
The term TPO stands for Thermoplastic Polyolefin. Believe it or not, TPO is actually in a broad family of rubber roofing materials. TPO is a blend of polypropylene and ethylene-propylene rubber. In comparison to other thermoplastic membranes, TPO resists mold growth, dirt accumulation, tears, impact and punctures. It is made to be flexible and can allow for a home’s or building’s movement or settling. Reinforced TPO membranes can handle a building’s thermal expansion and contraction more effectively than other single ply roofing products.
In general TPO membranes are manufactured with wider sheets and are light weight. This means that the material is easier to install and there is less seams. Less work and time associated with the installation translates into direct savings for you for the cost of installation.
