What is the effect of the thickness of the spacer layer on the energy saving of insulating glass?

This doesn't have much impact, so it depends on how big the material is and how big the aluminum strip is in the middle.

Summary. Hello dear! We're happy to answer for you! The thickness of the air layer of insulating glass is usually between 4mm and 20mm, and the thickness of the air layer has a great impact on the properties of insulating glass, such as heat insulation, sound insulation, anti-fogging, and light transmittance.

Is the thickness of the air layer of insulating glass affected by the thickness of the glass?

Hello dear! We're happy to answer for you! The thickness of the air layer of insulating glass is usually between 4mm and 20mm, and the thickness of the air layer has a great impact on the thermal insulation, sound insulation, anti-fogging, light transmittance and other properties of insulating glass. Touch the dust chain.

Specifically, the following factors need to be considered in the selection of air layer thickness:1Thermal Conduction Effects:

The thermal conductivity of the two-layer insulating glass (i.e., the thickness of the local air layer is 12 mm) is about that of a single layer of glass, which is much greater. As the thickness of the air layer increases, the thermal conductivity decreases gradually, so the choice of the thickness of the air layer should depend on the required thermal insulation performance.

2.Acoustic conduction effect: Similar to thermal conduction, the acoustic conductivity coefficient of hollow glass will also decrease with the increase of air thickness. Therefore, if the insulating glass needs to have a certain sound insulation effect, the thickness of the air layer also needs to be increased appropriately.

3.Anti-fogging effect: The anti-fogging performance of insulating glass mainly depends on the balance of humidity inside the air spring sensitive layer.

In the environment with high relative humidity, the effect of air layer thickness on anti-fogging performance is not significant. However, if the relative humidity of the environment is low, the increase in the thickness of the air layer can help improve the anti-fog performance.

4.Effect of light transmittance: Light transmittance refers to the proportion of light transmitted by the hollow trapped source excitation glass.

Since there are no pigments or impurities inside the air layer, the light transmittance of insulating glass socks is very high. Changes in the thickness of the air layer have little effect on the light transmittance, so the light transmittance is usually not one of the main considerations in the selection of air layer thickness.

In general, the thickness of the air layer has an important influence on the performance of Zhongheng closed glass. When choosing the right insulating glass, it is necessary to select the appropriate air layer thickness of the front barrier according to the actual requirements of thermal insulation performance, sound insulation performance, anti-fog performance, etc.

The composition of insulating glass: glass + air layer + glass (the most commonly used example: 5 + 9a + 5).

The sound and heat insulation effect of insulating glass mainly depends on the stability, drying, and thickness of the air layer, so it is not that the thicker the insulating glass, the better the thermal insulation effect, but the thicker the air layer of the insulating glass, the better the thermal insulation effect, for example, the thermal insulation effect of insulating glass with a thickness of 8+6a+8 is not as good as 5+9a+5.
