[China Glass Network] What is the difference between insulating glass and vacuum glass? Vacuum glass is to seal the two sheets of flat glass, leaving a gap in the middle, vacuuming the gap and sealing the vent. The inner surface of the two sheets of glass is coated with one or two transparent low-emission films. The hollow glass is called "hollow" and is not empty. There is "qi" in the middle of the two layers of glass. In most cases, "qi" is air, and the better quality is argon. Since the gas is not visible to the naked eye, it is said to be "empty. Empty glass is to draw a "vacuum" between the two layers of glass, basically it can be said that there is no gas, it is really empty. In the end, what is the difference between insulating glass and vacuum glass? What is the difference between insulating glass and vacuum glass? In contrast, vacuum glass is superior to the performance of insulating glass. Vacuum glass has excellent thermal insulation properties. It is used as window glass to make the winter room warm and warm. The indoor heating is not easy to be lost, which reduces the cost of heating and air conditioning and saves energy. Air conditioning is used indoors in summer, and air-conditioning is not easy to escape. Sound insulation performance is good, preventing noise interference and creating a quiet environment. In addition, in the winter, even if the outdoor temperature is very low, it is difficult to condense on the side of the window glass interior, which ensures a clear view without cleaning the dew condensation glass frequently. Another feature of vacuum glass is that it is much thinner than insulating glass, saving installation space and window frame material. At the same time, due to the good thermal insulation performance, its anti-condensation and fogging performance is also very good, which can avoid the unpleasant appearance of the condensation on the window and the invisible appearance of the dew soaking window sill. In winter, you can reduce the feeling of coldness in front of the window and the feeling of "surface wind" under your feet. The wind-resistant strength of vacuum glass is about twice that of insulating glass made of the same glass, but the impact strength is not as good as that of insulating glass. This weakness can be solved by combining vacuum glass. For example, in the required position, laminated glass technology can be used to add tempered glass to one side or both sides of the vacuum glass to form a safety vacuum glass with high impact strength and wind pressure resistance. Undoubtedly, this cost will increase accordingly. As for the price issue, the price of ordinary insulating glass is 100-200 yuan / square meter, and the quality is not good. The insiders know that the vacuum glass production process is more complicated than the insulating glass, the raw materials are more expensive, and the current production scale is smaller, so the price of vacuum glass is more expensive than the insulating glass. Vacuum glass is composed of two layers or three or four layers of glass, each of which is different, generally ranging from 300 to 800 yuan per square meter. According to industry insiders, with the changes in the decoration trend, glass has been widely used and production technology has been greatly improved. In the past, insulating glass even required more than 1,000 yuan per square meter. Now, with the improvement of technology, it has been reduced to one or two hundred yuan per square meter. Vacuum glass has also been reduced a lot. However, compared with other decoration materials, these two kinds of glass are more expensive, and can be selected according to the needs of the decoration. In home decoration, hollow and vacuum glass can be used on balconies, doors and windows to provide insulation, sound insulation and warmth.
