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.
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.
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.
