The translucent membrane spanning the ceiling at Heathrow Terminal 2, UK, by Luis Vidal Architects, completed 2014, is made from ethylene tetrafluoroethylene (ETFE) produced by Taiyo Europe (evening LED back-lighting). A membrane like this is much lighter and consumes significantly less material than a solid ceiling structure.
