Advantages, disadvantages and main problems of glass curtain wall application

glass curtain wall is not unfamiliar to you. You can also see many office buildings, commercial buildings and landmark buildings using glass curtain wall when walking on the street at ordinary times. Now many stores, villas and hotel rooms will also choose to use glass curtain walls for decoration. In fact, even the sunshine room we most often contact is also a kind of glass curtain wall, which is gradually becoming the aesthetic mainstream in modern urban architecture

the origin of glass curtain wall is the development

the continuous progress of glass manufacturing technology has promoted the application and development of glass in the construction industry. The development path and trajectory of glass curtain wall can be roughly divided into the following stages: the windows of houses in the early stage of human activities, the Gothic church construction period and its subsequent period, the enlightenment application of plant garden greenhouses and commercial corridors, industrial buildings, and the popularization of large areas of office and office buildings

it is internationally recognized that the building with the earliest application of glass curtain wall is the fiberforge system of Harold, San Francisco, USA, designed by Willis Jefferson Polk and built in 1918. It uses continuous glass fiber belt or carbon fiber belt building. It adopts reinforced concrete structure, and the glass curtain wall is hung on a cantilever cement board extending 3 feet from the axis of the outer wall, It has all the characteristics of modern architectural curtain walls: it has a structural system of glass panels and supporting glass panels, has a certain deformation capacity relative to the main structure, and does not bear the role of the main structure

After the reform and opening up, with the increasingly frequent exchanges with foreign countries, some foreign advanced construction technology and technology have been gradually introduced into China, and the construction curtain wall technology has made great progress in China. In 1981, the domestic leading glass curtain wall project appeared on the facade of the Canton Fair Exhibition Hall, which has the characteristics of modern glass curtain wall and can be used as the beginning of the era of glass curtain wall in China

why are glass curtain walls used

curtain wall is the coat of a building, the soul of a building, and the external expression of the level of architectural style. As a beautiful and easy-to-use design material, glass makes many designers rely on glass to create beauty in design. We can also find that there are more and more glass curtain wall buildings around us. Glass, which successfully uses the green element bismuth in the periodic table on low-cost solar cells, is also very consistent with architectural aesthetics. For example, it can create empty inspiration and a sense of extension

office buildings and other high-rise office buildings have a high demand for natural lighting, and the lighting of glass curtain walls is very good. The design of the glass curtain wall is white, and the waste plastic may make the interior of the building more open when the sky is full of light. The glass curtain wall is atmospheric and clear enough to see the scenery outside, so that people can enjoy the beauty and life in a transparent space, which brings vision and spirit to people. 1 Comfort on a large trip

advantages and disadvantages of glass curtain wall performance

the glass curtain wall adopts hollow glass composed of mirror glass and ordinary glass, and the interlayer is filled with dry air or inert gas. The insulating glass has two layers and three layers. The two-layer insulating glass is composed of two layers of glass and a sealing frame to form a sandwich space; Three layers of glass is composed of three layers of glass to form two sandwich spaces. Insulating glass has the advantages of sound insulation, heat insulation, frost resistance, moisture resistance, increased daylighting, and high wind pressure resistance

glass curtain wall also has some limitations, such as light pollution, large energy consumption and so on. Coated glass or coated glass is used on the curtain wall of the building. When direct sunlight and sky light irradiate the glass surface, the reflected glare is generated due to the specular reflection of the glass. However, with the development of glass curtain wall technology and the continuous emergence of new material technology, the materials used in glass curtain walls in buildings can better solve the problems of light pollution and energy consumption

the main problems in the use of glass curtain wall

safety problems are the most important ones to pay attention to after the actual use of glass curtain wall. The glass curtain wall has been damaged, cracked or even fallen off due to long-term use, and falling debris injured passers-by. Such accidents have indeed occurred, and there is more than one case. In fact, many local housing and construction departments have issued relevant notices to restrict the use of glass curtain walls, pointing out that large-scale use is not allowed without special use requirements, among which special requirements refer to public buildings such as airports, theatres, office buildings and hotels

there is also the cost problem. Compared with the traditional ceramic tile structure, the glass curtain wall is more expensive, and a comprehensive inspection of the curtain wall project should be carried out one year after the completion and acceptance of the curtain wall project, and then every five years. The inspection and maintenance price of the glass curtain wall in practical application is not low. However, the sensory enjoyment and building value improvement brought by glass curtain wall are also beyond the reach of traditional ceramic tile structure
