The Raw Materials of Glass Curtain Wall?

In recent decades, after continuous improvement, the quality of Glass Curtain Wall has been significantly improved: First, "tempered." After the toughening treatment (heat treatment) of the glass impact strength than ordinary glass increased by 3 to 5 times, and even if the fragmentation is only broken into sharp glass blocks without sharp corners. Second, "hollow." The curtain wall glass made of double (or even three), between the two pieces of glass filled with dry air or inert gas, can greatly enhance the insulation, heat insulation, noise performance. It is measured that when the outdoor temperature is -10 ° C, the temperature in front of the single-glazed window is -2 ° C, whereas the indoor temperature using the three-layer insulating glass is 13 ° C. It should be emphasized that the hollow glass filled with air must be dry, it is to prevent water vapor condensation in the inner layer, affecting the transparency. Third, "double silver." The glass is coated with two layers of very thin silver film, this "double silver glass" can well penetrate the visible light, but the solar heat radiation (infrared) reflected off. On hot summer days, double-decker double-silver insulated glass absorbs 90% of visible light and blocks up to 90% of solar radiation.

Improved Glass Curtain Wall, a new look, very popular, "the scenery inside and outside the infinite." From the outside, tall buildings seem to wear a beautiful glass coat; Into the building, the light is transparent, everywhere is the "big screen", panoramic view of the infinite scenery. During the day, the indoor bright hall greatly reduces the electricity consumption of artificial lighting. At night, the glass curtain wall is transparent and the building has become the "Crystal Palace". There are also other charming landscapes lit by the lights and never sleeps.

Due to these advantages of glass curtain wall in architectural design, it quickly became popular all over the world. Manhattan in New York, Ginza in Tokyo, Causeway Bay in Hong Kong, and Lujiazui in Pudong, Shanghai have all become glass curtain wall mansions. Although the glass curtain wall entered China only in 1984, China has become the number one glass curtain wall power in the past 20 years: the area of ?? Glass curtain wall soared to 200 million square meters, accounting for 85% of the world total; China's curtain wall glass production, then accounted for 75% of the world. Light is Shanghai, there are more than 3,000 buildings wearing a gorgeous glass curtain wall coat.

However, there are shortcomings of the Glass Curtain Wall: First, although the glass quality has been greatly improved, but it can not completely eliminate the phenomenon of self-explosion, in order to avoid falling from the sky "glass rain" hurt pedestrians, glass curtain wall building usually around the establishment of green belt; Second, the reflection intensity of the glass curtain wall is about 10 times that of ordinary decorative materials, and the "light pollution" caused thereby can cause harm to human health. Therefore, residential buildings, school buildings shall not be used glass curtain wall.
