Roof tensile membrane is a type of architectural covering made from a lightweight, flexible material such as ETFE (Ethylene Tetrafluoroethylene) or PTFE (Polytetrafluoroethylene). These membranes are tensioned over a supporting structure, forming a continuous, weatherproof surface. The real scene photo refers to an actual photograph of such a tensile membrane installed on a building's roof, showcasing its design and structure.
