Spectro-Weld™ TPO Reinforced Membrane Technical Data Bulletin (TDB)

Versico Spectro-Weld is a premium heat-weldable single-ply thermoplastic polyolefin (TPO) membrane, engineered to provide outstanding reflectance of solar radiation in new roof construction and re-roofing applications. Spectro-Weld TPO is primarily designed for appropriate photovoltaic (PV) applications where its solar reflectance of 0.88 will maximize sunlight-to energy conversion efficiencies. Spectro-Weld TPO has the highest CRRC reflectance rating of any single-ply product, which helps minimize heat gain from sunlight into the building envelope from the roof surface.
