ETFE foil

ETFE foil (ethylene tetrafluoroethylene) is a lightweight, durable, and transparent plastic material used in architectural roofing and cladding. Its high optical clarity allows sunlight to pass through while providing excellent resistance to weather, UV radiation, and chemical corrosion. ETFE foil is often used in innovative, modern structures like stadiums and atriums because it is flexible, easy to install, and can be formed into large, seamless surfaces. Its unique properties promote energy efficiency by enabling natural light while maintaining insulation, making it a practical and sustainable choice for large-scale architectural applications.
