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.
ETFE does not shrink or expand when heated.
ETFE can retain its transparency and strength for over 30 years. In addition, ETFE has a high level of heat retention, retaining longwave thermal radiation and creating a 'greenhouse effect', which can reduce energy costs by up to 30%.
ETFE is often called a miracle construction material for tensile architecture.
ETFE is strong enough to bear 400 times its own weight.
It can be stretchable to three times its length without loss of elasticity and can be repaired by welding patches of tape over tears.
