What we usually call glass filling refers to filling the middle layer of insulating glass with an inert gas - argon.
The purpose of inflating is to improve the thermal insulation performance of the glass, thereby achieving energy saving effects. According to performance simulation calculations, if common 70 series casement windows are used, equipped with 34mm insulating spacer glass, and paired with three-glass and two-cavity 12mm insulating glass, the thermal insulation performance of the glass can be improved by up to 6.43%. Although this data is a simulation result, in actual applications, it can significantly improve the heat conduction effect of windows.
Today we will first learn about the inflatable process of insulating glass.
There are two filling processes for inflatable glass: online filling and offline filling.
Online gas filling: During the insulating glass production process, the gas is inflated before the glass is joined. The gas filling process is completed automatically, with high efficiency and stable gas concentration. After inflating, the glass continues to the next step of production.
Offline inflation: After the combined insulating glass is punched in the heat insulation spacer, the air in the middle of the glass is replaced by inflating the holes. Offline inflation requires controlling the air flow state to ensure that the gas can evenly replace the air in the middle of the glass. In addition, make sure the hole is sealed after drilling.
