Is the insulating glass filled with an inert gas to prevent fogging?

The insulating glass is sealed, and sufficient molecular sieve is used to absorb the water vapor in the hollow cavity. During the production, attention should be paid to the control time and process. Then, with good raw materials, the insulating glass without inert gas can guarantee no fog for more than 10 years. of. So, since filling with an inert gas does not prevent fogging, what does it do? With argon as an example, the following points are what it really does:

After filling with argon gas, the internal and external pressure difference can be reduced, the pressure balance can be maintained, and the glass burst caused by the pressure difference can be reduced.

After inflating argon gas, it can effectively improve the K value of the insulating glass, reduce the condensation of the indoor side glass, and improve the comfort level. That is, the inflated insulating glass is less prone to condensation and frost, but not inflating does not cause fogging. The direct cause.

Due to the characteristics of argon as the inert gas itself, the heat convection in the insulating glass can be slowed down, and the noise reduction effect of the insulating glass can be further improved, that is, the insulating glass can be insulated and the sound insulating effect can be better.

Can increase the strength of a large area of ​​insulating glass, so that it will not collapse in the middle without support.

Increase the wind pressure resistance.

Because it is filled with dry inert gas, the water with moisture in the hollow cavity can be replaced to keep the environment inside the cavity drier and prolong the service life of the molecular sieve in the aluminum spacer frame.

When using low-emission LOW-E glass or coated glass, the filling gas is an inert inert gas, which can protect the film layer from reducing the oxidation rate and prolong the service life of the coated glass.
