The selection of glass type affects the energy-saving effect of windows during heating period

With the continuous progress of technology, there are more and more types of glass. Currently, the main glass varieties aimed at energy conservation include heat absorbing glass, coated glass, insulated glass, vacuum glass, etc. Among them, the promotion and use of insulating glass is a symbol of the progress of the times. Hollow glass is sealed by two or more layers of glass to seal the air layer, and the intermediate layer is filled with inert gas with high viscosity coefficient and low thermal conductivity coefficient to reduce convective heat transfer in the interlayer. Therefore, the design should determine the spacing of the glass appropriately based on the needs of thermal resistance and the economic scale of the frame material, and generally should not be less than 9mm. To improve the insulation performance of doors and windows, three glass panels can be made. In addition, glass coated with low radiation film can greatly reduce the radiation heat transfer between glasses. Of course, if insulating glass can be matched with LOW-E or SUN-E glass, due to its excellent optical and thermal properties, its insulation performance is more outstanding.
