My country has become the world's largest curtain wall door and window market

The curtain wall is the outer wall of the building. It is not load-bearing and hangs up like a curtain, so it is also called a hanging wall. It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. It is a building envelope structure that is composed of a structural frame and inlaid panels and does not bear the load and role of the main structure. The curtain wall can be divided into: building curtain wall, component building curtain wall, unit curtain wall, glass curtain wall, stone curtain wall, metal plate curtain wall, full glass curtain wall, point supporting glass curtain wall, etc. Common glass curtain wall structure forms: hidden frame, semi-hidden frame, exposed frame, point type, full glass, etc.

With the economic development in recent years, my country has become the world's largest curtain wall door and window market. The demand for building curtain wall doors and windows accounts for more than 2/3 of the total global demand, of which glass curtain walls account for more than 60% of all curtain walls. Other high-tech curtain wall products (smart curtain wall, ecological curtain wall, membrane structure curtain wall, etc.) account for a relatively small proportion, still less than 4%.

A large number of new environmental protection and energy-saving products such as aluminum alloy energy-saving doors and windows, FRP energy-saving doors and windows, aluminum-plastic composite doors and windows are emerging and new products are emerging. According to incomplete statistics, the market share of energy-saving doors and windows for buildings in various places has increased rapidly, and has accounted for 50% of the entire door and window market. Therefore, vigorously developing energy-saving doors, windows and curtain walls, whether economic or social benefits, are very huge. At present, the selection of domestic curtain wall materials has shifted from the previous single pursuit of modernization and technological content to the people-oriented trend of pursuing humanistic and artistic atmosphere, natural environmental protection, energy saving and noise reduction.
