The Difference Between Insulating Glass And Vacuum Glass

What is the difference between vacuum glass and insulating glass? There different performance, hollow glass, not empty "hollow" in fact, two layers of glass with a "gas", in most cases the "qi" is the air, the quality is better argon gas, it is due to the air is invisible to the naked eye, so he said to "empty".


The vacuum glass is a vacuum between the two layers of glass, which is essentially free of gas and is really empty.


Why does a thermos bottle keep warm for a long time? Because it is a vacuum layer between inside and outside the inside and inside, effectively obstructs the conduction of heat. The vacuum glass is the sealing of two pieces of sheet glass, leaving the space between the gaps, and the clearance is pumped into a vacuum and sealing the vent. Two pieces of glass are coated with a layer of transparent and low radiation film. The flask bottle is composed of two layers of glass shell, cavity, empty cavity and silver. Vacuum glass is the equivalent of a thermos flask made into a flat plate, and some people joke that the vacuum glass window is actually "putting a thermos bottle on the window".


If the thermos in the home leaks, it will not keep warm, which can show the difference between the gas and gas.


The data shows that the vacuum glass is two to three times better than the insulating glass, which is more than six times better than normal single glass, which is much better than the normal wall.

Another feature of vacuum glass is thinner than insulating glass, which can save space and window frame material. At the same time, because of the good thermal insulation performance, its anti-condensation fogging performance is also very good, but it can be removed from the window of the condensation fog caused by the absence of the view and the dew to soak the window sill and so on the annoying things. Winter can reduce the cold feeling of the window and the feeling of "surface wind" under foot.


In addition to the thermal insulation performance, the vacuum glass insulation performance is better than insulating glass.


The compressive strength of the vacuum glass is about twice as high as the insulating glass made of the same glass, but the impact strength is less than the insulating glass, which can be solved by combining vacuum glass. For example, in the desired position, the glass technology of the sandwich glass can be used on the side or both sides of the vacuum glass to make the safety vacuum glass which has high impact strength and anti-wind strength. Undoubtedly, such costs will increase correspondingly.


In recent years, the most widely used of new buildings in China is insulating glass. Hollow glass is also known as the "glass of today".


The vacuum glass starts late than the hollow glass, and the vacuum glass is still in its budding stage, regardless of the maturity and scale of the industrialization technology. But because it has a strong comprehensive performance advantage than the hollow glass, the development prospect is very bright. As the production scale expands and the process progresses, the price will drop sharply. A few years later, the vacuum glass is likely to replace the insulating glass as the mainstream product of the energy efficient glass, which can be said to be "tomorrow's glass".
