Glass curtain wall refers to a building container or decorative structure supported by a structural system and has a certain displacement capacity relative to the main structure, but does not participate in the load of the main structure. There are two types of walls: single-layer glass and double-layer glass. Glass curtain wall is a beautiful and novel way to decorate the walls of the building. Its biggest feature is that it seamlessly combines architectural beauty, architectural function, building energy conservation and architectural structure. It is not only simple, luxurious and modern, but also can reflect the surrounding scenery, have a good decorative effect, and integrate walls and windows, greatly reducing the weight of the building. The glass curtain wall of modern high-rise buildings uses a combination of mirror glass and ordinary glass, and the hollow glass is used in the cabin, which is filled with dry air or inert gas. Hollow glass can be divided into two layers and three layers. Double-layer hollow glass is composed of two layers of glass and a sealed frame to form a mezzanine space; three-layer glass is composed of three layers of glass, forming two spaces between the two layers. Hollow glass has the advantages of sound insulation, heat insulation, frost resistance, moisture resistance and strong wind pressure resistance. It has been measured that when the outdoor temperature is -10℃, the temperature in front of the single-layer glass is -2℃, while the indoor temperature when using the triple-layer insulating glass is 13℃. In the hot summer, the double-layer insulating glass can block 90% of the solar radiation heat. The sunlight can still pass through the glass curtain wall, but ordinary people do not feel hot when they touch it. The rooms with insulating glass curtain walls can be warm in winter and cool in summer, which greatly improves the living environment. Framed glass curtain walls are glass curtain walls supported by metal frames around the glass panels, mainly including: exposed framed glass curtain walls, semi-hidden framed glass curtain walls and hidden framed glass curtain walls.

Advantages

1. Aesthetics: The curtain wall has a variety of exterior designs. Different materials such as glass, stone and metal panels can be used, with different colors and textures to create a unique visual effect, highlighting the beauty and modernity of the building.

2. Non-load-bearing: The curtain wall does not bear the structural load of the main building. It is connected to the main structure of the building through a load-bearing structure system and only serves as a fence and decoration. This makes the design of the curtain wall more flexible, and lightweight materials can be selected if necessary.

3. Functions: In addition to the decorative function, the curtain wall also has many functions such as waterproofing, fire resistance, heat insulation and sound insulation. These functions can effectively protect the interior space of the building and improve the comfort and safety of the building.

4. Energy saving: The use of energy-saving materials such as hollow glass and low-emissivity glass, combined with double-layer or multi-layer structures, effectively reduces energy loss and improves the thermal insulation performance of the building.

5. Convenient maintenance: The curtain wall panels are relatively independent of the supporting structure system, and their maintenance and replacement are convenient. If some panels are damaged or need to be cleaned, they can be disassembled and installed separately without affecting the normal use of other parts.
