LandVac tempered vacuum glass does not have the problem of internal condensation and at the same time, the dew point of the outer surface is also very low. 

Taking the indoor temperature of 20°C and relative humidity of 70% as an example, LandVac tempered vacuum glazing will not condensate when the outdoor temperature is as low as -50°C, which not only maintains a transparent view but also avoids the growth of mould.

Note: Insulating glass will condense when the outdoor temperature is -3°C.
