The vacuum-mirror ensure quality
When mirror turns gray – vacuum is lost
Advantages
Nowadays window prices continue to increase. It is difficult for building owners to judge whether the window is still thermally effective or not.
Just a few standard IG fabricators utilize the expensive and complex test devices to check every IG produced, which leads to a significant number of inferior or defective products reaching the market. It may take years for the IG to look defective, but from day one, it may not have been performing as it should!
After a decade of development, ICESUN overcame this problem by employing a novel chemically activated Vacuum-Mirror™ in the VIG. If the mirror reflects, it means the degree of vacuum is intact. If the mirror becomes smaller or turns gray, it indicates that internal vacuum has been compromised. When vacuum is completely gone, the Vacuum-Mirror™ provides the indication.
Loss of mirror reflectance indicates heat transfer through the VIG has increased. It also indicates the Low-E coating may degrade which leads to a haze forming on the glass and loss of thermal insulation properties. Thoughtful design of ICESUN’s unique VIG Vacuum-Mirror™ ensures that the owner knows the performance status of their windows.
After more than a year with extremes reaching 100°C differential between interior and exterior, the tempered VIG is intact and only deformed 1%.
Deformation of glass is a common occurrence due to large temperature differences between the interior and exterior.
Minimizes Dew Condensation
When the outside temperature is lower than -5˚C, the inner surface of typical insulating glass windows experiences condensation. If the temperature is lower, windows will develop both frost and condensation, which seriously affect your view. Perhaps more importantly, the condensation forms droplets and runs down the inner surface of the glass damaging window frames, walls and floors. ICESUN Tempered Vacuum Insulating Glass extends the temperature limit of condensation by 25˚C (from -5˚C to -30˚C) which eliminates condensation and frost from forming on the glass. Even in extreme cold weather, you will enjoy a beautiful view and sunshine.
Wind Pressure Load Resistance
ICESUN Tempered Vacuum Insulating Glass is ultra-thin because it is constructed of two pieces of tempered glass with a narrow gap supported by metal pillars. 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.
