Glass curtain wall refers to a building envelope or decorative structure that has a certain displacement capacity relative to the main structure by the supporting structure system and does not share the effect of the main structure. There are two types of walls: single-layer and double-layer glass. The glass curtain wall is a beautiful and novel architectural wall decoration method, which is a distinctive feature of the modernist high-rise building era.
The glass curtain wall of the modern high-rise building uses hollow glass composed of mirror glass and ordinary glass, and the interlayer is filled with dry air or inert gas. Insulating glass is divided into two layers and three layers. The two-layer insulating glass consists of two layers of glass and a sealed frame to form a sandwich space; the three-layer glass consists of three layers of glass to form two interlayer spaces. Insulating glass has the advantages of sound insulation, heat insulation, frost resistance, moisture resistance, and strong wind pressure resistance.According to measurements, when the outdoor temperature is -10°C, the temperature in front of the single-layer glass window is -2°C, while the indoor temperature using three-layer insulating glass is 13 ° C. In the hot summer, double-layer insulating glass can block 90% of the solar radiation heat. Sunlight can still pass through the glass curtain wall, but most of the sun does not feel hot. The room with hollow glass curtain wall can be warm in winter and cool in summer, greatly improving the living environment.
