ETFE (ethylene tetrafluoroethylene) consists of modified copolymers of ethylene and tetrafluoroethylene. It has been widely used in the construction industry in recent years.
It has been suggested that the use of ETFE in construction can reduce build cost by 10% on small projects and up to 60% on large-scale projects. Costs are also reduced during the installation process when sheets of ETFE film can be 'welded' together with a blow torch and spans of up to 180 ft (55 m ) can be achieved with sufficient structural support.
