Vacuum glass is a new type of glass deep processing product developed based on the principle of thermos. The structure of the vacuum glass is similar to that of the insulating glass, except that the gas in the vacuum glass cavity is very thin and nearly close to the vacuum.
Vacuum glass

The vacuum glass seals the two flat glass sheets, draws the gap into a vacuum and seals the vent hole. The gap between the two glass sheets is 0.1-0.2 mm, and the vacuum glass is usually supported by uniformly distributed tiny metal particles. At least one of the two sheets of vacuum glass is generally low-emissivity glass, so that the heat lost by conduction, convection and radiation of the vacuum glass is lowered to a very low level, and the working principle is the same as that of the glass thermos. Vacuum glass is the fruit of glass technology and materials science, vacuum technology, physical measurement technology, industrial automation and building science, and cooperates with various disciplines, multiple technologies and various processes.

Vacuum glass is more common than ordinaryInsulating glassMore energy efficient, but vacuum glass production costs are higher than insulating glass.
