Vacuum Insulated Glass | 2018.06.28 | 1415
How can you quickly distinguish between vacuum glass and Insulated Glass

With the rapid development in various industries such as construction, automobile, decoration and renovation, home furniture, information technology, etc. and higher demand of people toward their living spaces and environment, functional processed products like safety glass, energy-saving insulated glass, and so on are widely used and applied. Due to the lacking of advertising and promotion, many people believe that vacuum insulated glass and insulated glass are the same. However, on the contrary, it is not true.

Speaking from the structural formation, there are large differences between vacuum insulated glass and insulated glass. Firstly, the gap between the two pieces of glass in vacuum insulated glass is a vacuum chamber. It is simply the absence of air. On the other hand, the gap between the two pieces of glass in the insulated glass is filled with dry air or inert gas. This difference has also resulted in a mere 0.1 to 0.2 mm gap in vacuum glass, while the smallest gap in the insulated glass is 6 mm. As such, the thinnest for vacuum insulated glass is 6 mm, and that for an insulated glass is 12 mm. The glass sides of a vacuum insulated glass are enclosed using metallic welding materials or the low-melting-point glass melting method; for insulated glass, it is enclosed with organic rubber.

The following steps can help you to quickly spot vacuum insulated glass:

Hold the glass nearer and closely observe. You can see uniformly distributed micro support pillars between the two glass panes;

The corner of the glass has an air evacuation port and a protective cap (except for the flat enclosure);

The glass sides are enclosed by solidified metallic welding materials or low-melting-point glass; the glass thickness is about 6 to 8mm.
