TPO (Rubber) roofing
TPO roofing is a single-ply thermoplastic membrane. A synthetic rubber, it is a blend of ethylene-propylene and polypropylene with scrim fillers such as talc, fiberglass, and carbon fiber that reinforce and improve its stability, strength, and performance but also add flexibility. TPO was first introduced in Europe during the 1980s and in the US since the 1990s. Today it is considered one of the fastest-growing segments of the commercial roofing market. That, in large part, is because TPO was developed to combine some of the best qualities of other roofing systems such as EPDM and PVC.
