ETFE or Ethylene tetrafluoroethylene, is a high-end material, found and developed 40 years ago. ETFE can be applied in a variety of Tensile Membrane Structures with single or multi-layer pneumatically inflated, with a weight equal to only 1% of the weight of glass. With a lifespan of over 30 years and good weather resistance, ETFE is becoming a great material for outdoor spaces in diverse climates.
