Vacuum double glazing, also known as double glazed or insulated glass, consists of two panes of glass separated by a vacuum-sealed space. The vacuum acts as an insulator, reducing heat transfer between the two panes and improving energy efficiency. This type of glass is commonly used in windows and doors to improve insulation and reduce energy costs. It also has the added benefit of reducing noise pollution by providing an additional barrier against outside sounds. Vacuum double glazing is available in a variety of thicknesses and can be customized to fit specific requirements for different applications. Overall, it is an excellent choice for those seeking to improve the energy efficiency and comfort of their home or building.

Parameter Value
Thickness From 4mm to 20mm
Vacuum Gap Usually between 6mm to 20mm, filled with a desiccant
U-value Measures the rate of heat transfer, lower U-value is better
Solar Heat Gain Measures the amount of solar radiation that passes through the glass
Visible Light Transmission Measures the amount of visible light that passes through the glass
Sound Insulation Measures the ability of the glass to reduce noise transmission

Note: The parameter values may vary depending on the specific product and manufacturer.

Refrigeration and cold storage: Double vacuum glass is used in refrigeration and cold storage applications to prevent heat transfer and maintain the desired temperature.

Display cases: Double vacuum glass is used in display cases and other retail applications to prevent condensation and maintain a clear view of the contents.




Q: What is double vacuum glass?

A: Double vacuum glass, also known as double glazed or insulated glass, is made up of two panes of glass separated by a vacuum-sealed space. The vacuum provides insulation and reduces heat transfer between the panes.

Q: What are the benefits of double vacuum glass?

A: The benefits of double vacuum glass include improved insulation, reduced energy costs, improved sound insulation, and reduced condensation.

Q: Can double vacuum glass be customized to fit specific requirements?

A: Yes, double vacuum glass can be customized to fit specific requirements such as thickness, U-value, solar heat gain, and visible light transmission.
