Glass curtain wall refers to the supporting structural system and glass composition. Relative to the main body, the structure has a certain displacement capacity, do not share the main structure of the role of the building envelope or decorative curtain wall structure, because of its absorption of infrared ray, reduce the solar radiation into the room, the indoor temperature and other advantages, so in China's construction engineering has been widely used. Glass curtain wall is a kind of beautiful and novel decorative method of building wall, which is a remarkable feature of the era of modernist high-rise buildings.
Under normal circumstances, the glass curtain wall is made of aluminum alloy or other metal rolled hollow type rod to do the skeleton, with glass closed and become the house enclosure wall. There are single and double glazed walls. Reflective insulating glass 6mm thick, wall weight about 40kg/m2, light and beautiful, not easy to pollution, energy saving and other advantages. The inner side of the outer glass curtain wall is coated with colored metal coating, which looks like a mirror from the outside.
Advantages and disadvantages of glass curtain wall
Advantages:
Glass curtain wall is a new type of wall, it gives the biggest characteristic of the building is the architectural aesthetics, architectural function, architectural energy saving and architectural structure and other factors organically unified, the curtain wall building from different angles to present different colors, with the change of sunlight, moonlight, lighting to give people dynamic beauty. In the major cities of all continents in the world have built magnificent and gorgeous glass curtain wall buildings, such as New York World Trade Center, Chicago oil Tower, Sears Tower have used glass curtain wall.
Disadvantages:
Glass curtain walls also have some limitations, such as light pollution, large energy consumption and other problems. In addition, the glass curtain wall is not clean and transparent pollution resistance, especially in the atmosphere of more dust, serious air pollution, drought and less rain in the northern region, glass curtain wall is easy to dust and dirt, which for the urban landscape, not only can not increase "light", but lose "face". The material used is inferior, the construction quality is not high, the color is not uniform, the ripples are different, due to the uncontrollable light reflection, resulting in the chaos of the light environment. However, with the continuous emergence of new materials and new technologies, these problems of modern curtain wall are gradually brought into the comprehensive research system of architectural modeling, building materials and building energy conservation, and are deeply discussed as a whole design problem.
