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 method for decorating building walls. 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 landscape, 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 partition, which is filled with dry air or inert gas. Hollow glass can be divided into two-layer and three-layer. Double-layer hollow glass is composed of two layers of glass and a sealed frame to form a mezzanine space; triple-layer glass is made of three layers of glass, forming 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 is -2℃, while the indoor temperature when using triple-layer insulating glass is 13℃. In hot summer, double-layer insulating glass can block 90% of the heat of solar radiation. Sunlight can still pass through the glass curtain wall, but ordinary people do not feel the heat when in contact with it. 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 glass panels, mainly including: exposed frame glass curtain walls, semi-concealed 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 various materials such as glass plate, stone and metal, combined 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 object. It is connected to the main structure of the building through a load-bearing construction 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. Functionality: In addition to the decorative function, the curtain wall also has many functions such as waterproofing, fire resistance, thermal 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: Curtain wall panels are relatively independent of the supporting structure system, and maintenance and replacement are convenient. If some panels are damaged or need cleaning, they can be disassembled and installed separately without affecting the normal use of other parts.
