How to distinguish the authenticity of hollow glass in doors and windows

With the improvement of people's living standards, hollow glass is preferred when installing doors and windows, which can ensure the home is comfortable and dry, because it is equipped with a desiccant that absorbs moisture, preventing moisture from invading the room. It can also isolate 40 dB of noise, effectively reducing noise pollution. There are many hollow glass doors and windows on the market, and fish and dragons are mixed, so how to identify its quality? Let's take a look.

How to distinguish the authenticity of hollow glass in doors and windows

In fact, "insulating glass" is not completely "empty". The spacing between two layers of insulating glass is generally around 8 mm. Experiments have shown that if the spacing within 8 mm is completely vacuum, the pressure of the atmosphere is likely to directly crush the glass. Therefore, high-quality insulating glass must be filled with inert gases argon and krypton between the interlayers. After filling, the K value is detected, and its thermal insulation performance will be more excellent.

If the hollow glass you buy does not contain fillers in the interlayer, it is really "empty". It is very likely that you simply fix the two pieces of glass together. At best, it can only be called double-glazed glass. The effect is relatively poor. The limit value of the heat transfer coefficient of qualified insulating glass, k, can be reduced from 3.5 to 2.8, which quickly locks the temperature and does not allow the heat in the house to be lost.

Because there is water vapor in the air, if the hollow glass of the fake doors and windows is likely to enter the water vapor, it will cause fogging and blooming in the interlayer, and even moldy spots. Therefore, in order to deceive customers, some blackhearted manufacturers directly use a sandwich Perforated aluminum strips, and then placing a granular desiccant between the aluminum strips, can only achieve the effect of mixing fish beads, and can not really improve the performance of double glazing. After a long time, after the desiccant fails, it will be the same There is a phenomenon of water vapor.

How to "identify the right body"? In winter, check whether there is freezing between the glass. In the spring and summer, see if condensation will occur. Another feature is that the material of the window frame is also one of the important signs, because the insulating glass is generally made of plastic steel and not aluminum alloy.

Conclusion of the article: The method of judging the authenticity of hollow glass in doors and windows is introduced here for everyone. I hope the above will help you to distinguish insulating glass effectively. For more related knowledge, please continue to pay attention to the information platform of this website.
