A Clear Trend in Roofing Technology

The article discusses a clear trend in the use of lightweight, transparent and translucent materials for roofing and facade applications in major sports facility designs. The use of ethylene tetrafluoroethylene (ETFE) has become the material of choice due to its higher mechanical strength and better thermal performance. ETFE roofing and facade applications create an authentic, outdoor atmosphere in an indoor, conditioned space while providing a protected and temperature-controlled experience. This material is lightweight and reduces structural support requirements and costs, allowing for lighter and more elegant structures. Additionally, natural light can reduce lighting and energy costs during operation, and a clear but static roof eliminates the need for mechanization and the operational and maintenance costs of a retractable roof solution.
