What Is PTFE coated fiberglass?

Polytetrafluoroethylene (PTFE) coated fiberglass is the most durable membrane used in facade systems. PTFE coated fiberglass provides uncompromised and unequalled beauty, longevity, and functionality. PTFE was developed by DuPont in 1938 and has been used in building applications since the 1970s.

  • Projects requiring superior fire resistance
  • Exhibition spaces
  • Museums
  • Transportation hubs
  • Leisure
  • Retail
  • Projects located in tropical, arid or extremely cold climates

What are the advantages of PTFE coated fiberglass?

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

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

Maintenance benefits of PTFE coated fiberglass

  • Regularly self-cleaning with rainwater
  • A manual clean every 2-5 years is recommended, but because the fabric strength can support human weight, this can be done easily with jet-washers or soft brushes and access to the roof
  • 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

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

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

How is PTFE coated fiberglass used?

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.
