It is the most effective way to reduce air-to-air heat transfer through glass.
Insulating glass combines two or more panes of glass that are hermetically-sealed to keep in the air space in between in order to reduce thermal losses. This leads to lower energy consumption and enables perfect transparency by reducing water condensation on the warm air side. Generally, it allows two very different requirements – keeping heat in during colder weather and keeping heat out during warmer weather.
It is usually used for external purposes such as for windows and glass wall panels of buildings. It contains all the features for safety and sound insulation, and is weather-proof and dust free.
