Glass curtain walls refer to a building envelope or decorative structure supported by a structural system that has a certain shear 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 walls are a beautiful and novel way to decorate the walls of a building. Their biggest feature is that they seamlessly combine architectural beauty, architectural function, energy saving and architectural structure. They are not only simple, luxurious and modern, but also reflect the surrounding landscape, have a good decorative effect, and integrate walls and windows, thereby greatly reducing the weight of the building. The glass curtain wall in modern high-rise buildings uses a combination of glass and ordinary glass, and hollow glass is used in a cabinet 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 laminated frame to form an intermediate space; three-layer glass is composed of three glasses, creating two spaces between the two layers. Hollow glass has the advantages of sound insulation, heat insulation, frost resistance, moisture resistance and resistance to strong wind pressure. The measured outdoor temperature is -10 °C, while the temperature in front of the single-layer glass is -2 °C, and the indoor temperature when using 3-layer insulated glass is 13 °C. In the hot summer, double-layer insulated glass can block 90% of solar radiation. Sunlight can still penetrate through the glass curtain wall, but it will not heat ordinary people when touched. Rooms with 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 composed of: exposed glass curtain walls, partially concealed glass curtain walls and concealed glass curtain walls.

Advantages

1. Beauty: The curtain wall has a variety of exterior designs. Different materials such as glass, stone and metal plates 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 the installed structural system and only serves as a barrier 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 its decorative function, the curtain wall has many functions such as waterproofing, fire protection, 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-emissivity glass combined with double or multi-layer structures can reduce energy loss and improve the thermal insulation performance of the building.

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