Vacuum glass is a new type of glass deep-processing product. High-tech vacuum glass is a cutting-edge product with only independent intellectual property rights in China's glass industry. Vacuum Glass For Buildings is the most advanced transparent and thermal insulation (thermal insulation and sound insulation) material in the world. Tempered vacuum glass plays a great role in the aspects of energy conservation and sound insulation. Vacuum building glass from ICESUN is formed by pumping, welding and edge sealing two layers of ordinary glass at high temperature through high-tech means. The air pressure of the two-layer glass inter layer is a vacuum lower than 10-4Pa, which makes the gas heat transfer negligible, so it achieves excellent thermal insulation and sound insulation effect. Nowadays, Safety Vacuum Glass has been mainly used for passive house, skylight, doors and windows, solar water heater, freezer door, automobile, train doors and windows, greenhouse and other industries.
