Background

With the increasing of the environmental awareness of people, energy-saving glass products with heat preservation and insulation functions are gradually welcomed by the market, the demand of energy-saving glass is rapidly increased, and the market development potential is huge. The house area built in every year in China is about 20 hundred million square meters, the buildings which can reach the energy-saving standard specified by the state only account for about 10 percent, and most buildings belong to high-energy-consumption buildings. China is a big energy consumption country, about 30% of energy consumption comes from buildings, and the energy consumption of the buildings in China per unit area is more than 3 times that of developed countries. Wherein, the energy consumption of the glass accounts for about 50 percent of the energy consumption of the whole building. Compared with single-layer common glass, the energy-saving glass can save energy by about 75 percent, so that the energy-saving glass is not easy to push in China, and the industry development can meet important opportunities.

The doors and windows of modern buildings need to consider a series of important functions such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, burglary prevention, sun shading, weather resistance, operation hand feeling and the like, and also need to consider the comprehensive performance of production equipment, profiles, fittings, glass, viscose, sealing elements and other links, so as to finally form high-performance system doors and windows.

At present, the application of technologies such as common hollow glass, Low-E film, warm edge, vacuum glass, inert gas filling and the like reduces the heat transfer coefficient of the glass, but still has the problems of large energy-saving space and more use. For example, the common hollow and vacuum glass has low radiation blocking rate and poor heat insulation effect in summer; the vacuum glass is easy to explode automatically under the condition of large indoor and outdoor temperature difference, and the mass production scale cannot be achieved according to the current technological level; the coated glass is easy to be oxidized and loses the heat insulation and energy saving functions, etc.

Three-glass two-cavity glass windows are adopted in partial areas of China, although the heat transfer coefficient is further reduced, the radiation blocking performance is poor, the self weight of the window is heavy, the requirements for bearing of a window frame and a building are high, and the construction difficulty is increased.
