What is the difference between Insulating Glass and Vacuum Glass?





Vacuum glass is to seal two flat glasses with a gap between them, and use a vacuum cleaner to seal the exhaust hole. The inner surface of the two pieces of glass is coated with one or two layers of transparent low-emissivity film. Insulating Glass is not actually empty. , There is gas between the two layers of glass. In most cases, the gas is actually air, and the better quality is argon. Because the gas cannot be seen with the naked eye, it is said to be "empty". The empty glass draws a "vacuum" between two layers of glass. Basically, it can be said that there is no gas, but it is actually empty. Finally, what is the difference between Insulating Glass and Vacuum Glass?

Vacuum glass has better performance than Insulating Glass. Vacuum glass has extraordinary thermal insulation properties. Using it as window glass can quickly warm the room in winter and prevent the loss of indoor heating, thereby reducing heating and air conditioning costs and saving energy. Air conditioning is used indoors in summer, and it is not easy to escape. The sound insulation performance is good, which can prevent noise interference and create a quiet environment. In addition, in winter, even if the outdoor temperature is very low, it is difficult to condense on the indoor side of the window glass, thereby ensuring a clear view and no need to clean the condensed glass frequently.

Another feature of vacuum glass is that it is much thinner than Insulating Glass, which can save installation space and window frame materials. At the same time, due to its good thermal insulation properties, its anti-condensation and anti-fog properties are also very good, which can avoid invisible outdoor scenery and window sill dew and other annoying things. In winter, it can reduce the cold feeling in front of the windows and the wind feeling on the surface under your feet.

The wind pressure resistance of vacuum glass is about twice that of Insulating Glass made of the same glass, but the impact strength is not as good as Insulating Glass. This weakness can be solved by combining vacuum glass. For example, where needed, laminated glass technology can be used to add clear tempered glass to one or both sides of the vacuum glass to form a safety vacuum glass with high impact resistance and wind pressure resistance. Undoubtedly, this fee will increase accordingly.

Insiders know that the production process of vacuum glass is more complicated than that of Insulating Glass, and the raw materials are more expensive. The current production scale is small, so the price of vacuum glass is more expensive than Insulating Glass. The industry believes that with the changes in decoration trends, glass has indeed been widely used and production technology has been greatly improved. However, compared with other decorative materials, both types of glass are more expensive, and the appropriate amount can be selected according to the decoration needs. In home decoration, hollow and vacuum glass can be used for balconies, doors and windows to play a role in heat insulation, sound insulation and warmth.
