In the processing of laminated hollow glass, there are mainly the following technological characteristics, through which the performance of laminated insulating glass can be improved.

Heat transfer of laminated hollow glass is mainly carried out by radiation heat transfer. If ordinary transparent glass with high transmittance and LOW reflectivity is used, the heat insulation performance of laminated insulating glass is much lower than that of coated or low-E glass with high reflection and low transmittance.

Increasing the plane size of laminated hollow glass can reduce the heat loss per unit area and improve the overall heat insulation effect of laminated insulating glass. At the same time, in the assembly process of laminated insulating glass doors and Windows, if the glass buckle is not installed well or sealed tightly, the whole window or glass will be breathable inside and outside, resulting in convection, resulting in energy loss and affecting its performance.

Mainly through the thickness control, the heat transfer of turbulent air flow is formed inside the laminated hollow glass, and the mutual interference of hot and cold gas or the mutual interference of the rising and falling air flow is controlled to control the convection heat transfer.

The inert gas filled inside the laminated hollow glass can reduce the heat insulation and sound insulation performance of the laminated insulating glass. The heat insulation and sound insulation performance of laminated insulating glass can be improved by filling argon and sulfur fluoride.
On the one hand, if the edge of the laminated hollow glass is not sealed well, the proportion of water gas entering the laminated insulating glass through the sealing rubber layer should be increased, and the service life of the laminated insulating glass will be reduced. On the other hand, if the side material of laminated insulating glass has good thermal conductivity, then the heat insulation coefficient of laminated insulating glass will be improved, and the heat insulation performance will be decreased.
