What Is A Curtain Wall

The curtain wall is the outer wall enclosure of the building, which is not load-bearing and hangs like a curtain, so it is also called "curtain wall", which is a lightweight wall with decorative effect commonly used in modern large-scale and high-rise buildings. It is a building envelope or decorative structure composed of panels and supporting structure systems, which can have a certain displacement capacity relative to the main structure or a certain deformation ability of itself and do not bear the role of the main structure (the external wall frame support system is also a kind of curtain wall system).
