Tensile translucent membrane, also known as tensioned membrane structure, is a type of architectural structure that uses flexible materials, such as ETFE (Ethylene Tetrafluoroethylene) or PTFE (Polytetrafluoroethylene), to form a continuous, tensioned skin. These membranes are known for their ability to span large distances without support columns, providing unique aesthetic qualities and versatile applications in architecture and design.
