The vacuum-mirror shows vacuum very well


When mirror becomes grey means vacuum is gone


Nowadays, windows prices continue increasing. It is very hard for users to judge whether the glass is still effective or not. Only few people can use an expensive and complex professional testing equipment to check each piece of glass every day, which leads to a lot of inferior products flooding in the market.

We spent almost a decade and finally overcame this worldwide problem: successfully set a getter mirror in tempered vacuum glass. If the mirror exists, it means the degree of vacuum is great; if the mirror becomes smaller, it means vacuum has been reducing. When the vacuum is lost, the mirror would disappear. Mirror disappearance indicates conduction and convection within the glass significantly increase; it also indicates LOW-E coating will soon fail due to oxidation so the radiation heat transfer will greatly increase. Being conscience product, the thoughtful design of getter mirror for tempered vacuum glass, helps the user to always understand the status of their windows.

After 385 days in 100 degree Celsius differential between exterior and interior glass, the tempered vacuum glass is intact and only deform 1%.
Deformation and warpage of glass is common due to a big temperature difference between exterior and interior glass.



Minimizes Dew Condensation


When the outside temperature is lower than -5 ˚C, the inner surface of insulating glass windows experiences condensation. If the temperature is lower, windows will develop both frost and condensation, which seriously affect your view. At the same time, the condensation runs down the inner surface of the glass, and damages window frames, walls and floors. Relying on its superior heat-insulating abilities, ICESUN Tempered Vacuum Glass extends the temperature limit of condensation from -5 ˚C to -30 ˚C, which allows you to avoid condensation and frost on your windows. Even in extreme cold weather, you will enjoy the beautiful view and sunshine.

Wind Pressure Load Resistance



ICESUN Tempered Vacuum Glass is ultra-thin because it is formed by two pieces of tempered glass supported by rigid steel and connected under atmospheric pressure. It has higher resistance to deformation under external force. We have the world’s only industrial tempered vacuum glass technology, which doubles the wind pressure resistance and anti-shock effect compared with common vacuum glass and tempered Low-E argon insulating glass.

Sound Insulation and Noise Reduction



With increases in urban population and traffic, noise can become a major nuisance. ICESUN Tempered Vacuum Glass effectively blocks the transmission of sound, especially powerful permeable low-frequency sounds. The integrated sound-blocking ability of ICESUN glass is more than 11dB better than that of ordinary insulating glass.



Comparison of VG and IG (R value=22 h·ft2·˚F/Btu)


The centre-of-tempered vacuum glass R value is 22. The centre-of-insulating glass R value is 7.
The thermal insulation performance of VIG is 3 times as IG’s. At the same time, the service life of VIG is 2 times as IG’s.
From the overall performance perspective, the value of VIG is equivalent to six times as IG’s.
