The window wall is divided into two types: single-layer and double-glazed. window wall is a beautiful and novel method of building wall decoration, which is a distinctive feature of the era of modernist high-rise buildings.

Window wall refers to the non-load-bearing exterior wall enclosure of a building, usually consisting of panels (glass, metal plates, slate, ceramic plates, etc.) and supporting structures behind (aluminum beams, columns, steel structures, glass ribs, etc.).

Window wall refers to the building envelope or decorative structure that can have a certain displacement capacity relative to the main structure through the load-bearing structure system and does not share the role of the main structure.

The window wall is the outer wall of the building. It is not load-bearing and hangs like a curtain, so it is also called a hanging wall. It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. The building envelope is composed of a structural frame and inlaid panels, and does not bear the load and effect of the main structure.

Unit curtain wall and frame curtain wall have their own advantages and disadvantages. Regardless of the facade type, general design and functional guidelines must be followed to meet the aesthetic requirements of the building. Any type of curtain wall can be more suitable for specific situations to meet the needs of the building.
