ICESUN Vacuum 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, which doubles the wind pressure resistance and anti-shock effect compared with common vacuum glass and tempered Low-E argon insulating glass. There are some specific characteristics of ICESUN Tempered Vacuum Glass:

1. Basic Characteristics
Tempered vacuum glass consists two panes of glasses which are separated by an array of supporting pillars and welded together by glass at very low temperature. Vacuum between glass is 10-4Pa, where the heat convection does not exist, the heat conduction drops to minimum, with the LOW-E layer reflecting more than 95% of the infrared radiation, so the heat between the inner and outer glass plates can not be exchanged, and the excellent heat insulation effect is achieved. Tempered vacuum glass size: maximum 3000 x2000 mm; minimum 200 x200 mm; thickness 6~20 mm.

2. Science and Technology Innovation
2.1 Vacuum Eye

We have solved this worldwide problem 15 years ago. We set up this nail size vacuum eye at the corner of glass. When the internal vacuum is constant, the vacuum eye remains unchanged. When the vacuum degree drops, the vacuum eye becomes smaller. The vacuum degree disappears (when the vacuum glass leaks) and the vacuum eye disappears. The disappearance of vacuum eye indicates that the conduction and convection in the glass will increase greatly; it also indicates that the LOW-E film will soon oxidize and the radiation heat transfer will also increase greatly; at present, only ICESUN products have vacuum eye design (invention patents and trademarks are granted), which allow users to know the life of their windows at any time.

2.2 Low Temperature Welding
The welding process of low temperature glass retains the toughness of tempered vacuum glass, and the strength of glass is increased by 5 times. ICESUN tempered vacuum glass is tested in United States and granted SGCC safety certification.

2.3 Long Life, Resistance to Condesantion
Aerospace grade welded glass and tempered glass are perfectly combined to block gas leakage. 50 years of high vacuum, the low radiation energy saving activity of nano-silver film is perfectly preserved, the air leakage of organic glue and metal edge is avoided, and the international problem of LOW-E glass oxidation failure is cured by the US IGCC certification provement, dew condensation only appears at -30℃.

3. Basic Technical Features
3.1 Sun Protection
Tempered vacuum glass could reduce indoor glass temperature by 30℃, and nano-silver film could block infrared and ultraviolet. With these benefits family are kept away from air conditioning disease, and eyesight and skin are protected. We did one test that ICESUN tempered vacuum glass was installed in the test room, the indoor and outdoor temperature difference was 100℃, the test lasted 385 days continuously, the tempered vacuum glass was intact without damage, the deformation was only 1%, and the ultra-high insulation performance remained unchanged. This shows that tempered vacuum glass could be used safely in any harsh environments.

3.2 Resistance to Wind Scale 9
The wind resistance performance of tempered vacuum glass is twice as much as insulating glass. Tempered vacuum glass is an ultra-thin material formed by the connection of two panes of tempered glass and titanium alloy under atmospheric pressure. It has high deformation resistance under the action of external force. Our industrial tempered vacuum glass technology improves its wind pressure resistance and strength, far better than ordinary vacuum glass and argon filled tempered LOW-E insulating glass.

3.3 Sound Insulation and Noise Reduction
ICESUN tempered vacuum glass sound insulation performance is 11 decibels better than conventional insulating glass. The maximum sound insulation of tempered vacuum glass can reach 41 decibels. For different needs of users, we can compound hollow or glued glass to make super quiet transparent glass with strong sound insulation. Tempered vacuum glass keeps you away from noise hazards.

3.4. Protect the Eyes, Protect the Fetus
3.5. Suitable for Various Installation Angles and Elevations
3.6. Ultra-light & Thin, Invariant

ICESUN 12.4mm tempered vacuum glass, compared with 20~50 mm conventional insulation glass is much lighter, which pose less pressure on structural frame materials, hardware components. Windows are not easy to droop and deform, and their service life is longer.
