Laboratory testing for the vacuum glazing, double glazing and single glazing

The most common glazing types for domestic buildings is single glazing, insulating glazing (also known as double glazing) and vacuum glazing. Currently, single glazing is becoming a thing of the past and is being replaced with its more durable and efficient counterpart, double glazing or vacuum glazing. Double glazing has been widely used in the EU and China. The unit price of double glazing has improved because of mass manufacturing. This paper describes four types of glazing systems as well as mathematical analyses of the energy transfer process through a computer programme using a computer simulation to analysis performance. The results show that vacuum glazing enjoys the best thermal performance. The overall U-value can achieve about 1.05 W/m2*K, which can have huge commercial potential for vacuum glazing. The carbon emission reduction potential of using vacuum glazing across Wuhan has also been analysed.
