duroTUF TPO membrane is a high quality TPO (ThermoPlastic Polyolefin) which has been formed into a membrane sheet and reinforced with a heavy duty polyester scrim, used to provide waterproofing protection for a variety of roofing and exterior deck applications. The duroTUF TPO membrane is reinforced with polyester fabric to provide excellent wind uplift resistance, puncture resistance and finished physical properties. TPO formulation was developed to allow for extreme pliability, flexibility and weldability during installation. Along with such installation advantages, our TPO’s state-of-the-art formulation helps our product to resist extreme weather conditions, including ultraviolet radiation and high surface temperatures

duroTUF TPO membrane is a single ply polyester reinforced thermoplastic polyolefin (TPO) membrane system which comes in 3.0m wide rolls by 30.0m long with the option of 1.14mm and 1.5mm thick.

The duroTUF TPO option will provide significantly less laps in compared with other options with excellent lap bonding. duroTUF TPO is also available in a fleece back which is used in acoustic deck systems and where substrates will have movement issues.


Hot Air Welded Seams/Laps

Hot air welding of the overlapped 50mm seams works by applying very hot air between the two membrane surfaces, softening and fusing the surfaces together, thereby creating a permanently fused, bonded sheet. One of the major advantages of hot air welding is the fact that the seam comes to full weld strength immediately.
