Polytetrafluoroethylene (PTFE) coated fiberglass is the most durable membrane used in tensile membrane systems. Comprised of a woven glass fiber base fabric covered with Teflon®, PTFE coated fiberglass provides uncompromised and unequalled beauty, longevity, and functionality when it comes to tension fabrics. PTFE was developed by DuPont in 1938 and has been used in building applications since the 1970s.


Panels of PTFE coated fiberglass are welded together to create the desired shape. If needed, the panels are supported with cables. The fabric is then tensioned over a lightweight structural system.

PTFE coated fiberglass offers a variety of benefits ranging from its durability to its superior safety features.

Durability benefits of PTFE coated fiberglass

  • Lifespan exceeding 30 years
  • Can withstand temperatures of -100 F to +450 F (-73 C to +232 C)
  • Tensile strength of 500,000 PSI (more than 10 times the tensile strength of steel)
  • Chemically inert
  • Weather-resistant
  • Resistant to micro-organisms
  • Moisture-resistant
  • Immune to UV degradation
  • Resists the build-up of environmental pollution
  • Does not discolor over time
  • Does not become brittle over time

Environmental benefits of PTFE coated fiberglass

  • Energy Star rated
  • Cool Roof Rating Council certified
  • PTFE coated fiberglass membranes reflect up to 73% of solar heat and hold only 7% on their exterior surface
  • PTFE coated fiberglass provides thermal insulation to a degree similar to conventional glazing
  • U value of approximately 4.0-5.0 for a single-layer application
  • High shading coefficient, resulting in energy savings over traditional glass glazing

Maintenance benefits of PTFE coated fiberglass

  • Regularly self-cleaning with rainwater
  • No internal cleaning required
  • PTFE coated fiberglass installs in a buff color and bleaches to a bright white with sun exposure, so the structure self-maintains a bright white appearance over time

Design benefits of PTFE coated fiberglass

  • Flexible
  • Lightweight (approximately 0.3 pounds per square foot, or 1.5kg per square meter)
  • Single panels can be fabricated in almost any size and shape
  • Large spans can be reinforced with structural cables
  • PTFE coated fiberglass has highly elastic properties (10.5 x 106 PSI modular elasticity)
  • It does not significantly expand or shrink under stress
  • It provides a significant degree of noise absorption and sound attenuation
    PTFE coated fiberglass can support up to 1,000 pounds per square inch (18 kg per mm)
  • It can become a stage for beautiful and dramatic lighting effects

Lighting benefits of PTFE coated fiberglass

  • Highly transparent
  • It allows natural daylight to reach the people below while also providing shading
  • It is translucent, but still screens out ultraviolet rays and excess heat
  • Reflects 75% of sunlight
  • Absorbs 10% of sunlight
  • Transmits 15% of sunlight

Safety benefits of PTFE coated fiberglass

  • US Fire-Rated Noncombustible ASTM E-136, Class A Smoke ASTM E-84, Burning Brand E-108, CSFM Title 19, Pass NFPA 701
  • Inherently non-flammable
  • Class 1 rating in surface spread of flame testing
  • UK Class 0 performance in BS476 pt6 fire propagation tests

KieranTimberlake: Printed Tensile Cladding at Rice Unversity

We are pleased to have collaborated with KieranTimberlake and the outfit of a parking structure on the Rice University Campus. In their blog post, they describe the concepts they employed to create an iconic sculptural element. For more details see the KieranTimberlake blog post.

The Increasing Importance of Durability

While tensile fabric has several distinct advantages over more traditional materials like glass, one of the most important may be its ability to withstand severe weather events. Our tensile structures and tensile facades  in Miami, Jacksonville, Houston, Fort Worth, Waco, and Atlanta did not sustain any damage or require any repair despite enduring events ranging […]
