1. The size of the glass
Increase the size of insulating glass, hollow glass can reduce the heat loss per unit area, improve the overall effect of insulating glass insulation. As already mentioned, there are three ways of energy transfer, convective heat transfer, radiation heat transfer and conduction heat transfer.
2. Thermal conductivity of glass
In the above analysis, we can understand that if a reasonable space layer design and construction, can basically control the convection through the insulating glass and conduction heat transfer.Insulated glass heat transfer is mainly conducted by means of radiation heat transfer, if the use of high transmittance low reflection (radiation) rate of ordinary transparent glass, the insulating glass insulating performance is lower than the use of high-reflection (radiation) of coated glass or low-e glass.
3. The edge of the insulating glass seal
On the one hand, if the edge of the insulating glass seal is not good, the water vapor through the sealant layer into the proportion of insulating glass will increase, the failure rate of insulating glass will be accelerated. Any product, regardless of its initial performance is good, however, its life is very short, this product can not be said to be a good product.The other hand, if the insulating glass edge material thermal conductivity is very good, insulating glass edge and glass sealant heat transfer is relatively large, insulating glass insulation coefficient will increase, insulation performance decreased.
4. Air species and humidity between layers
In the insulating glass filled with inert gas, can reduce the insulating glass insulation, sound insulation performance, such as filled with argon and sulfur fluoride can improve the insulating glass insulation, sound insulation performance; insulated glass interior water vapor Content increases, will produce internal condensation or water, thus affecting the hollow glass aesthetic effect, will result in the transmission of insulating glass heat transfer coefficient increases, reducing the heat insulation effect.

5.The thickness of the gas spacer layer
The thickness of the gas spacer layer is mainly through the control of the thickness of the insulated glass to form a turbulent airflow within the heat as much as possible to control the gas hot and cold air flow to interfere with each other or to increase and decrease the flow of air to interfere with each other to control the convective heat transfer.
