What is What Is ETFE (Foil/Film): 

Ethylene Tetrafluoroethylene (ETFE) is a fluorine-based plastic polymer that offers a creative and lightweight alternative to glass. Developed over 40 years ago, ETFE has a similar light transmission to glass, but at just 1% of the weight. With a lifespan of over 30 years and excellent weathering properties, ETFE film is becoming the material of choice for outdoor and outdoor/indoor spaces in a variety of climates.
