A building curtain wall refers to the non-load-bearing exterior wall cladding of a building, typically composed of panels (glass, metal, stone, ceramic, etc.) and a supporting structure behind them (aluminum beams and columns, steel structures, glass ribs, etc.).
A building curtain wall is an exterior cladding structure or decorative structure composed of a supporting structural system and panels, capable of some displacement relative to the main structure, and does not share the loads of the main structure.
A curtain wall is the exterior wall cladding of a building; it is non-load-bearing and hangs like a curtain, hence also called a suspended wall. It is a lightweight wall structure with decorative effects commonly used in modern large and high-rise buildings. It consists of a structural frame and inlaid panels, and is a building envelope structure that does not bear the loads and actions of the main structure.
