ETFE

ETFE is quickly gaining popularity in North America. It has been used on innovative and prominent projects, including the U.S. Bank Stadium in Minneapolis and Mercedes Benz Stadium in Atlanta.

The material has many attractive attributes, combining design practicality and structural cost saving with an aesthetic appeal to broaden creative possibilities.

What is ETFE?

ETFE (ethylene tetrafluoroethylene) is a fluorocarbon-based polymer originally developed by the aeronautics industry for its high resistance to corrosion and temperature variations. Architects have discovered ETFE as a viable building material and are leveraging its light weight and unique transparency properties.

Transparency in Performance

The material allows for up to 95% transparency and the passing of ultraviolet light, which is responsible for the promotion of photosynthesis and plant growth, making it an ideal material for stadia. ETFE is also customizable. The amount of solar shading and transparency can be adjusted by modifying the translucency, density, number of layers, and design patterns.

ETFE systems use air-filled pneumatic panels, which significantly reduces the roofing load, and in turn cost, of the structural support systems necessary compared to traditional roofing, especially for large-span roofs.

ETFE allows owners and architects to create stunning buildings that provide greater natural light while reducing structural loads. Project teams see an increased benefit in the early engagement of ETFE Specialists to provide detailed design input. In construction, specialists support the team through a diligent review of the installation.
