The heat transfer coefficient and shading coefficient of vacuum glazing can be designed and selected according to requirements. For buildings in different climate regions, vacuum glazing with different thermal performance can be selected according to local building energy-saving requirements. The cold areas in the north should focus on heat preservation to minimize the loss of indoor heat; the areas in the south, which are hot in summer and cold in winter, should not only pay attention to heat preservation in winter, but also pay attention to heat insulation in summer to reduce the entry of solar radiant heat in summer. For the lighting surfaces of the same building with different orientations, the thermal performance of vacuum glass should also be different. Only attention to detail can guarantee the best effect of energy efficiency. Vacuum glazing improves the quality of indoor environment, which reflects in noise, no condensation and comfort level.
Noise:
Generally speaking, the weighted sound insulation of vacuum glazing is more than 36dB, and the composite vacuum glazing can reach more than 40dB. The use of vacuum glazing windows or curtain walls can effectively isolate outdoor noise and improve the indoor acoustic environment. The sound insulation performance of ICESUN tempered vacuum glass is 11 decibels better than that of ordinary insulating glass. The maximum sound insulation of a single piece of tempered vacuum glass can reach 41 decibels. According to the different needs of users, we can compound hollow or laminated glass to make ultra-quiet transparent glass with very strong sound insulation performance in the world. In a word, tempered vacuum glass keeps you safe from noise hazards.
Anti-condensation:
Under normal circumstances, the super thermal insulation performance of vacuum glazing can completely isolate the indoor and outdoor ambient temperature, and the anti-condensation factor is more than 75. Even in the cold winter of minus 20 ℃ outside, the temperature difference between the temperature of the glass indoor surface and the indoor air will not exceed 5 ℃, which is much higher than the condensation temperature. The condensation temperature of ICESUN vacuum glazing is lower than minus 50 degrees.
Comfort level:
The excellent thermal insulation performance of vacuum glazing is easy to maintain the constant temperature and humidity in the room. The difference between the indoor surface temperature of the glass and the room temperature is less than 3~5℃, which eliminates the serious cold and heat radiation phenomenon, reduces the temperature gradient in front of the window, and significantly improves the comfort level of the indoor environment.
The life expectancy of ICESUN tempered vacuum glass 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, which greatly suppresses the radiation heat transfer and ensures the heat transfer coefficient (U value) of the vacuum glass. As low as 0.4W/(m2·K). At the same time, the thermal insulation performance of ICESUN vacuum glazing is 2-4 times that of insulating glass, and 6-10 times that of single-piece glass. It can meet the requirements of the international passive house for the heat transfer coefficient of doors and windows when used independently.
