Tpo membrane can provide combined benefits of both epdm rubber and pvc roofs but at a more economical cost than pvc.
Thermoplastic pvc tpo roof membrane.
Roofing calculator in the building trades the acronym tpo stands for thermoplastic polyolefin a material originally developed for pond liners and used extensively for roofing since 1989.
Thermoset membrane roofingis fully cured during manufacture so it cannot be bonded to an adjacent sheet with heat or solvents.
It s therefore not surprising that tpo roofing systems are quickly growing in popularity and demand in both residential and commercial flat roof markets.
The most common thermoplastic roof membranes are pvc and tpo.
Sikaplan is a cost competitive single ply pvc roofing membrane designed for low slope roofing applications.
