PTFE, or polytetrafluoroethylene, is a Teflon™ (trade mark of Chemours) for coating glass fibre membrane that is extremely durable and weather resistant. It is used for large-scale permanent tensile and membrane structures that typically require low flammability, durability, strength and compliance with tough construction codes. PTFE varies in translucency from 7% to 15% and reflects between 68%-75% of incident sunlight. The light transmitted is diffused and glare-free. 

At Temme // Obermeier, we have extensive knowledge of PTFE coated glass fibre fabrics and Tenara™ PTFE fabrics, we help clients solve ambitious design and technical challenges bringing their sophisticated membrane structures to life.


PTFE-coated glass fibre fabric has impressive properties that make it an obvious choice for tensile and membrane architecture. It displays excellent resistance to extreme weather conditions, UV and chemicals. PTFE has a low coefficient of friction and is easy to clean. It is extremely durable and has a service life in excess of 25 years.
