Denver Union Station, Colorado, USA, features a tensile fabric canopy engineered and produced by Structureflex. The roof consists of polytetrafluoroethylene (PTFE) coated glass fibre, combined with a single layer of ethylene tetrafluoroethylene (ETFE) film. Sunlight is filtered to allow daylight to pass through the weatherproof canopy without the accompanying heat. Image Structureflex.
