ETFE, or Ethylene tetrafluoroethylene, is an exciting addition to the selection of membrane materials. It is a highly transparent extruded film applied either as a single layer membrane or as a multilayer pneumatically inflated cushion. The material has good UV stability, as well as chemical and heat resistance. At just 1% the weight of glass the material is revolutionizing the construction industry – allowing us to create structures previously unimaginable.
