PTFE, or polytetrafluoroethylene, is a TeflonÂ®-coated woven fiberglass membrane that is extremely durable and weather resistant. PTFE fiberglass membranes can be installed in climates ranging from the frigid arctic to the scorching desert heat with a project life in some cases exceeding 30 years.PTFE fiberglass coating is chemically inert, capable of withstanding temperatures from -100Â°F to +450Â°F (-73Â°C to +232Â°C).TFE fiberglass membranes can be installed in climates ranging from the frigid arctic to the scorching desert heat with a project life in some cases exceeding 30 years.
