Commonly used glass curtain walls nowadays are designed with double-glazed windows. They are two pieces of glass joined together with a hollow structure in the middle. This design is also called hollow glass. Double-glazed windows have very good characteristics, both in terms of sound insulation and insulation, which far exceed those of ordinary windows. Then, with respect to the fog problem of double-glazed windows, the following Xiaobian will simply introduce it to you.
About double glazing:
The sealed double-glazed window is composed of two layers of glass, an air layer in the middle. The thickness and shape of the inner and outer layers of glass (9) and (10) are different. The gap is treated with cheap sound-absorbing and sound-insulating insulation material, which changes the window. The physical performance solves the problems of the common double-glazed air curtains with thick interlayers, high cost of multi-layer composite glazing, heavy load on sashes, aging of rubber mats, and inconvenience of replacement.
Double glazing:
1. Energy conservation: Energy conservation for doors and windows has become China's national policy, with doors and windows accounting for more than 20% of the building area, of which glass accounts for more than 70% of the area of ​​doors and windows. From the perspective of the loss of energy, 70% of the energy loss of the entire building guardianship was lost from doors and windows.
We all know that single-glazed doors and windows are the most destructive point of cooling (heat) in buildings, and the heat transfer coefficient of hollow glass is only 1.63-3.1m/wk, which is 29%-56% of single-layer glass. Heat loss can be reduced by about 70%, greatly reducing the load of cold (warm) air conditioning. Obviously, the larger the window area, the more obvious the energy-saving effect of insulating glass.
2, sound insulation: Another major function of insulating glass is to reduce the noise of the decibels. General hollow glass can reduce noise by 30-45dB. The soundproof principle is that the air in the sealed space of the hollow glass, due to the adsorption of the high-efficiency molecular sieves filled in the aluminum frame, becomes a dry gas with a low sound conduction coefficient, thereby forming an acoustic barrier. If the inert gas in the sealed space of the hollow glass can also improve its sound insulation effect.
Double glass window fog
The double-layer glass fogging is the cracking of the sealant, but the ingress of water is not only a problem of cracking, because the installation does not open the sink on the profile, or the sink has been blocked. If the water surface is higher than the lower profile, it is possible that the leaking water will flow in from above (this is rare), no matter which kind of glass the glass needs to be opened and redone. The person who is looking for the installation can do it (If you spend money, you do not need to replace the whole glass). Many people have encountered this problem. When the two layers of glass enter the water, when the sun radiates, the mist rises inside. If you enter the dust, it will have a great impact on its lighting and aesthetics.
cause:
1. No open pressure balance hole and drain hole or unreasonable opening of the water can not cause the water to drain out. After long-term vaporization of water vapor, it enters the glass interlayer and generates fog.
2. The installation position of the septum is unreasonable. The septum is affixed along the edges of the glass, leaving no gaps. This can easily cause the septum to come in direct contact with the rain, and after it is adsorbed, generates vapor in the glass.
3. The glass is not tightly sealed, and the four-sided sealant is unevenly applied, with leakage.
Solution:
1. Use hollow glass as much as possible, hollow glass can greatly avoid this phenomenon.
2. Glass spacers should be installed. The middle spacer should be arranged 1-2mm away from the glass and 3-4mm from the underside of the glass. In this way, it is possible to avoid contact between the septum strips and water. Of course, good septum strips with good quality and low water absorption rate should be selected.
3. The glass must be tightly sealed and carefully handled. The main causes of this problem in actual production are caused by poor sealing.
4. Apply a layer of glass glue on the outside of the bottom layer to ease the contact of the septum with rainwater.
5. The opening of the air pressure balance hole and drain hole is very necessary.
The above points are the summary of this site for everyone to sum up the double-glazed window fog information, I believe we will have a certain understanding after reading, so that everyone will know a lot, if we still have those who want You can check it out on our website.
