ICESUN provides Tempered Vacuum Glass with premium quality on thermal insulation, sound insulation, wind resistance, long life and sun proof, suitable for buildings, windows, greenhouse, etc. Through the strong combination of chemical agents, aerospace grade welded Vacuum Glass and tempered glass block gas leakage and overcome the sealing failure of brittle sealing materials under the same conditions. At the same time, the high vacuum life of 50 years can maintain the high vacuum degree of the vacuum glass cavity for a long time, and greatly reduce the failure phenomena such as performance attenuation in various harsh environments. High-Tech Vacuum Glass eliminates internal condensation. Moreover, the excellent heat insulation capacity makes the inner surface of the Safety Vacuum Glass free of condensation even if the outdoor temperature drops to - 50 â??. ICESUN Environmental Vacuum Glass has stronger heat preservation function than brick wall, greatly saving energy and reducing consumption.
