[China Glass Net] Choosing a good door and window frame is a more important standard for the use of doors and windows, and the quality of the door and window glass determines the impact of the door and window products on the home environment. Xiao Bian often troubles a layer of water vapor on his glass when it rains. For everyone to have more experience in the purchase of door and window glass, today we will come together to see what is the quality of the door and window glass?

The door and window glass directly determines the heat insulation, sound insulation effect, energy saving effect and anti-fog effect of the window. The energy-efficient door and window glass can greatly reduce the cost of heating and cooling. The qualified insulating glass window can save the cooling and heating costs in one year. Hundreds of dollars, according to the normal service life of 30 years, the direct economic benefits of hollow glass windows can reach 10,000 yuan.
There are three kinds of glass for double glazing, namely: double glazing, insulating glass, vacuum glass.
Double glazing <br> <br> double glass may be understood as a simple superposition of the two layers of glass, the intermediate filled with air, or without any sealing treatment, the sound energy efficiency has improved only slightly in the conventional glass based on single It is simply unable to meet today's building energy efficiency requirements. However, due to the extremely low production threshold and the difference in appearance from insulating glass and vacuum glass, it is difficult for consumers to distinguish three kinds of glass, and conceptually, mass consumers do not know the difference, so double The glazing windows also have a considerable proportion in the pseudo-high-end glazing market.
Vacuum glass
Vacuum glass is a double-layer glass with a vacuum inside. Since the interior is vacuum, the thermal insulation effect of this glass is theoretically strong because vacuum has no energy-transmitting medium, and heat and sound cannot be transmitted in vacuum. . However, the inside of the vacuum glass is vacuum, and the glass needs to withstand a large external air pressure, which is prone to small explosions, and an internal explosion-proof device must be installed. Vacuum glass is very demanding in the production process. At present, there are few enterprises in energy production, and high cost leads to vacuum glass being directly confined to the large-area customized high-end commercial building curtain wall market. Vacuum is not seen in ordinary household door and window products. glass.
Insulating glass
The insulating glass is treated by double-layer glass sealing treatment, and an inert gas such as nitrogen or helium gas is added in the middle to achieve the effect of sound insulation and heat insulation, and the functions of heat insulation, sound insulation and anti-fog are second only to vacuum glass. Due to the high energy consumption of the vacuum glass production process, although the insulating glass can not compare with the vacuum glass in its own energy-saving effect, the comprehensive environmental protection and energy saving even exceeds the vacuum glass. It is also the most popular glass category for high-end doors and windows in China. Its comprehensive energy saving and building energy efficiency have reached the level of building energy conservation advocated by the state. Its production cost and mass production process are relatively simple and suitable for popular applications.
How to judge three kinds of door and window glass
We know the difference between the three types of glass. When choosing a door and window product for home decoration, how do you judge which one is it?
On the front, double-glazed, no need to distinguish, as long as the two layers of glass are superimposed, they are double-glazed. If the inert gas is sealed on the basis of this, it is the insulating glass. If it is sealed on this basis and the internal air is evacuated, Vacuum, therefore, many businesses are confused about the concept of insulating glass, vacuum glass, double glazing, even if it is insulating glass, there are manufacturers who say that it is double glazing, so it is necessary to ask the merchant some details. For example, ask if the inside is filled with nitrogen or air.
Second, how to distinguish hollow glass? Good quality insulating glass is generally produced in a dust-free closed workshop. There is no dust or imprint in the middle. If the glass is found to be blurred and both sides are wiped, it is definitely not acceptable. . The more effective way to distinguish is: when the weather is cold, the glass is not foggy. When the temperature is normal, use a piece of ice on one side of the glass. If the inside of the glass is fogged, it is an unqualified insulating glass.
Third, the so-called vacuum glass window on the market is actually a suction hole on the basis of the insulating glass, the internal air is evacuated, and then the air hole is closed. Generally speaking, it is like a vacuum storage bag for household use. However, the storage bag is a soft material. It is possible to draw a relative vacuum, and the door and window glass are hard materials. It is necessary to simply pump the air inside. It is impossible. These vacuum glasses are actually a part of the internal air drawn out relatively thin, and the effect is similar to that of the insulating glass. Another problem is that after a few years, the pore plugs are aging and leaking seriously, and the effect will become worse and worse, and later become double-glazed. Therefore, the choice of vacuum glass is that all the vacuum glass in the home decoration, most of them are just hoes!
In addition to these kinds of detection methods that everyone can do, there are some professional methods, but they are not suitable for ordinary families. Of course, depending on the nature of the three glasses, many people in the life can still find out Methods.
