Double glasing is formed by combining two glasses under factory conditions with dry air between them. Double glasing units, also called insulating glass, reduce heat losses by half compared to single glazing. The most important benefit of the insulating glass is that it maintains the temperature in the spaces with the heat control it provides. In addition, thanks to the coated insulating glass, the solar heat input is reduced by 40%, keeping the spaces cool in summer. Thanks to these features, heat-insulated double glazing greatly reduces the use of air conditioning and electricity. In addition, it is a very effective material in sound insulation. It is a preferred application in many places with its aesthetic appearance.
