What to do if the insulating glass fogs?
The main materials that make up insulating glass can be ordinary float glass or coated glass (thermal inversion) Radiation film or low radiation film glass), heat absorbing glass (all kinds of colored glass), safety glass (tempered glass, laminated glass), etc., and develop towards functional glass such as self-cleaning glass.
The problem of fogging on insulating glass is caused by many reasons. The following are detailed reasons and solutions for reference.
Reasons and solutions for fogging of insulating glass:
1. When installing hollow glass windows, the construction process is poor. After a certain period of use, the sealant inside cracks, causing water vapor to enter the interlayer of the hollow glass. As the temperature increases, the water vapor evaporates and becomes small water droplets when in contact with the glass surface, leading to the phenomenon of fogging of the hollow glass.
Solution: If the phenomenon of fog on the insulating glass is caused by the sealant not being tightly sealed, the sealant on the insulating glass can be removed with tools, and the glass window can be cleaned again. After it dries, the painting process of the glass sealant can be carried out.
2. During the installation of double-layer hollow glass, due to the incomplete installation of the water tank inside, the water surface was higher than the profile, resulting in water flowing into the interlayer of the double-layer glass. Under the irradiation of sunlight, water vapor forms mist, resulting in fogging of hollow glass.
Solution: If the sink position of the double-layer hollow glass window is not installed properly, the hollow glass window should be removed and reinstalled.
3. When installing insulating glass, if there is no gap between the partition strip and the edge of the glass when pasting, it is because when rainwater comes into contact, it will adsorb rainwater onto the double-layer glass, leading to fogging of the double-layer glass. If the difference between indoor temperature and outdoor temperature is too large, and the indoor air humidity is too high, it will cause the phenomenon of hollow glass fogging.
Solution: If the partition strip in the double-layer insulating glass has been installed, glass gaskets can be added to the double-layer glass window. In addition, the original middle partition strip can be removed and reinstalled. Pay attention to maintaining a certain distance between the bonding position of the partition strip and the edge of the glass window, usually 2mm is the most suitable. And when installing the glass window, do not get water on the partition strip to avoid affecting its installation quality. If the difference in temperature is too large and causes fogging, you can open the window for a while to reduce the difference in temperature between indoor and outdoor, and wait until the upper fog dissipates.
FAQ for insulating glass:
1. What gas is filled in the insulating glass
The hollow glass is filled with argon gas. Because the limit value of the heat transfer coefficient of insulating glass can be reduced by 5% compared with that in vacuum state after filling argon, which means better thermal insulation performance.
2. What to do if the interior of the insulating glass is dirty
You can use some desiccants to absorb the moisture inside the insulating glass. So that it looks clear and clean. The insulating glass is dirty, which is likely due to the failure of the edge sealing of the insulating glass, so something dirty will enter. At this time, we will clean the inside of the insulating glass again. Then use some good sealing materials to seal the outer edge of the insulating glass, which can reduce the appearance of dry, special, and atomized insulating glass.
