What is the difference between a glass curtain wall and aluminum alloy doors and windows?

Glass curtain wall, also known as building curtain wall, curtain wall, is a kind of façade frequently used in modern architecture. It is generally composed of metal, glass, stone and artificial board. It is installed on the outermost layer of the building and acts like a wall. Beautiful, windproof, rainproof, energy-saving, etc., the curtain wall does not bear any structural load, only connected to the structural plate or column to withstand its own weight and resist wind pressure.

Aluminum alloy doors and windows refer to aluminum alloy doors and windows, referred to as aluminum doors and windows, which are made of aluminum alloy extruded profiles for frames, rafts and fan materials. Including aluminum alloy as the force-bearing member (the member that bears and transmits the self-weight and load), the wood and plastic composite door and window, referred to as aluminum-wood composite door and window, aluminum-plastic composite door and window.

For a long time, the definition of the curtain wall and the door and window in the industry has not been unified. Both of them belong to the building maintenance structure, and they do not share the force of the main structure. Some boundary practices make the qualitative doors and windows or the curtain wall become a problem. In order to ensure the appearance and consider the cost saving, many companies often use the door and window materials to design and manufacture the curtain wall effect. To some extent, it not only brings trouble to the construction acceptance, but also the maintenance structure thus produced also poses a hidden danger to the safety. . In order to avoid the continuation of such conditions, the concept of the glass curtain wall is clearly defined in the "Technical Specifications for Glass Curtain Wall Engineering": it consists of a supporting structural system and a panel, which can have a certain displacement capacity relative to the main structure, and does not share the main structure. The external maintenance structure or decorative line structure that is affected.

One point is mentioned here: there is a certain displacement capacity relative to the main structure. The door and window as the maintenance member of the support in the hole of the main structure cannot meet the ability of the main body structure to have a certain displacement. In the curtain wall design, the overall frame is suspended on the outside of the main structure, and the relative displacement can be ensured by designing measures such as expansion joints.
