PTFE coated fiberglass fabrics is also called architectural teflon membrane. PTFE architectural membrane is a new type of building material, it is a kind of composite material made of PTFE coating and special strength woven glass fiber in 3μm diameter, the material is soft comparing to traditional building material such as stone, steel, wood, brick and concrete, thus suitable for various shapes. PTFE-coated fiberglass membrane can come in a solid or a mesh product. PTFE (Polytetrafluoroethylene) membrane consists of a woven fiberglass fabric, coated with Teflon®, making it Class “A” 100% non-combustible, extremely durable, and weather resistant with self-cleaning properties far superior to those of most other structural materials. The chemically-inert PTFE fiberglass architectural membranes can tolerate climatic conditions ranging well outside the most extreme environments on earth (-100°F to +450°F or -73°C to +232°C), with expected design lifespans in excess of 25 years. Its low-surface free energy easily allows for complete cleaning by rainwater alone, provides total immunity to degradation by UV radiation.
