Glass curtain wall refers to a building enclosure or decorative structure that is supported by a structural system and has a certain displacement capacity relative to the main structure, but does not share 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 building wall decoration method. Its biggest feature is that it organically 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, has a good decorative effect, and integrates 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 hollow glass is used in the compartment, which is filled with dry air or inert gas. Hollow glass can be divided into two layers and three layers. Two-layer hollow glass is composed of two layers of glass plus a sealed frame to form a mezzanine space; triple-layer glass is composed of three layers of glass to form two interlayer spaces. Hollow glass has the advantages of sound insulation, heat insulation, frost resistance, moisture resistance, and strong wind pressure resistance. It is measured that when the outdoor temperature is -10℃, the temperature in front of the single-layer glass window is -2℃, while the indoor temperature using triple-layer insulating glass is 13℃. In the hot summer, double-layer insulating glass can block 90% of solar radiation heat. Sunlight can still pass through the glass curtain wall, but ordinary people do not feel hot when they come into contact with it. Rooms with insulating glass curtain walls can be warm in winter and cool in summer, greatly improving the living environment.
Frame-supported glass curtain walls are glass curtain walls supported by metal frames around the glass panels, mainly including: exposed frame glass curtain walls, semi-hidden frame glass curtain walls, and hidden frame glass curtain walls.

Advantages

1. Aesthetics: The curtain wall has a variety of exterior designs. It can use a variety of materials such as glass, stone, and metal plates, combined with different colors and textures to form a unique visual effect, enhancing 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 the supporting structure system and only serves as a enclosure and decoration. This makes the design of the curtain wall more flexible, and lightweight materials can be selected as needed.

3. Functionality: In addition to the decorative function, the curtain wall also has multiple functions such as waterproofing, fireproofing, 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-E 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 panels of the curtain wall are relatively independent of the supporting structure system, and maintenance and replacement are convenient. When some panels are damaged or need to be cleaned, they can be disassembled and installed separately without affecting the normal use of other parts.
