The thermal insulation performance of tempered vacuum glazing is close to that of wall. Compared with ordinary hollow glass window or Low-E hollow glass window, the thermal insulation performance of vacuum glass window has obvious advantages. According to the actual test of the national construction engineering quality supervision and inspection center, the vacuum glass window is used in cold areas, and the energy saving can reach more than 50% in winter. Therefore, whether it is glass window or glass curtain wall, the transparent envelope is no longer the short board of building energy conservation, and the energy consumption of the whole building can be significantly reduced to meet the specified indicators of green building. That`s to say, tempered vacuum glazing improves the energy saving standard of buildings.

Due to the needs of building functions, when the window wall area ratio exceeds the specification requirements and needs to be weighed and calculated, the thermal index of vacuum glass window can meet the requirements of weighing and judgment.
For the needs of architectural appearance design, when a part of the enclosure structure can not meet the requirements of the specification and needs to be weighed and calculated, the thermal indicators of vacuum glass curtain wall can meet the requirements of weighing and judgment.
The expected service life of ICESUN tempered vacuum glazing can reach more than 50 years. It has a high vacuum inner cavity, so that the gas heat transfer can be ignored. At the same time, it adopts high-performance Low-E glass and the Low-E layer reflects more than 95% of the infrared radiation, so as to greatly inhibit the radiation heat transfer and ensure that the heat transfer coefficient (U value) of tempered vacuum glazing is as low as 0.4W / (M2·K). At the same time, the thermal insulation performance of tempered vacuum glass is 2-4 times that of hollow glass and 6-10 times that of single glass. Independent use can meet the requirements of international passive room for heat transfer coefficient of doors and windows.
