Polytetrafluoroethylene is a Teflon-coated woven fiberglass membrane that is extremely durable and weather resistant. PTFE Fiber Glass membranes can be installed in climates ranging from the frigid arctic to scorching desert heat with an expected project life exceeding 30 years. PTFE Fiber glass coating is chemically inert, capable of withstanding temperatures from – 100F to +450F. The Low-surface free energy of the material creates a surface which is readily cleaned by rainwater. PTFE’s Fiberglass yarns maintain ultimate tensile strength of 500,000 PSI and a modulus of elasticity of 10.5 x 106 PSI compared to steel which offers 40,000 PSI and 29 x 106 PSI respectively
