Why is the broken bridge aluminum in the market all insulating glass instead of vacuum glass?

Broken bridge aluminum doors and windows are energy-saving doors and windows composed of broken bridge aluminum profiles, hardware, and glass. Now, all the aluminum doors and windows in the market are made of insulating glass instead of the vacuum glass that customers think. Why are all the bridge breaking aluminum doors and windows in the market all made of insulating glass instead of real empty glass?

Insulating glass, insulating glass bridge broken aluminum doors and windows are energy-saving doors and windows composed of broken bridge aluminum profiles, hardware and glass. Now the market almost all bridge broken aluminum doors and windows are made of insulating glass, rather than the vacuum glass customers think. Then why are the broken bridge aluminum in the market all made of insulating glass instead of vacuum glass? Insulating glass, insulating glass is a kind of product with two or more pieces of glass, separated evenly by useful support, and bonded and sealed around, so that the glass layers form a dry gas space. This product has the function of sound insulation, heat insulation, anti condensation and energy consumption reduction, and is widely used in construction, transportation, refrigeration and other occupations.

Vacuum glass is a new type of product. It uses properly dispersed particles as the distance. The gap layer is only 0.1 ~ 0.2 mm. There is no gas in the vacuum cavity, and the vacuum degree reaches more than 0.1 PA. As a new generation of energy-saving glass, it has better heat insulation and heat preservation functions, and its heat preservation function is about 4 times of that of single piece ordinary glass. Due to the high thermal resistance of vacuum glass, it has better anti condensation and frost functions, so it is very beneficial to the winter daylighting in severe cold areas. Vacuum glass is an impact on energy saving.

In addition to the structure of the window, the maximum heat conduction and radiation area of the window is glass. We can achieve good energy saving effect by selecting and reasonably using the glass varieties. The vacuum glass is so good, why is it used very little in the market? The main reason is that the manufacturing process of vacuum glass is high, and the cost is not low. If it is used in the broken bridge aluminum doors and windows, the price of the vacuum glass is higher than that of the broken bridge aluminum, and the gap of the vacuum glass is only 0.1 ~ 0.2 mm, so the bottom cannot be installed in the broken bridge For aluminum, it can be used in curtain wall or general aluminum alloy doors and windows. The minimum glass gap of bridge broken aluminum doors and windows is 6 mm. Therefore, it is not practical to use vacuum glass on bridge broken aluminum doors and windows. Therefore, the glass in the market of bridge broken aluminum doors and windows is hollow glass. As an energy-saving door and window, broken bridge aluminum can be analyzed from two aspects. From the big aspect, China is facing great pressure of energy conservation and emission reduction. Reducing the power consumption of building doors and windows is one of the useful energy-saving ways. From a small point of view, if energy-saving doors and windows can really have a good energy-saving effect, in addition to saving social resources, it can also save money for more customers. After all, heating and air-conditioning are used every year, and it is still a big expense. Therefore, bridge broken aluminum doors and windows have become the mainstream environmental protection doors and windows in the market.
