When the outside temperature is lower than -5 ° C, the surface of the insulating glass will condense. With its superior thermal insulation capability, the centre condensation temperature of the tempered vacuum glass drops to -30 °C. Used in the freezer, saving electricity costs more than a thousand yuan each year. According to the different needs of customers, it is also possible to combine a special insulating glass outside the tempered vacuum glass.
