THERMAL INSULATION GLASS

Insulating glass allows natural light to enter the room and helps reduce the negative effects of cold outdoor temperatures by reflecting heat back into the interior.

Ug represents the thermal transmittance coefficient of the double-glazed window and is measured in W/m²K. The lower this value, the better the thermal insulation.

The use of low-emissivity (Low-E) glass reduces the heat exchange by radiation between the two panes of insulating glass.

Low-emissivity glass is a type of glass that has a coating of metallic oxides (most commonly silver) with a thickness of just a few microns. This coating does not affect light transmission but significantly improves the thermal insulation performance of the glass.

A further increase in the insulating capacity of the glass can be achieved by using a gas with lower thermal conductivity than air, the most commonly used being argon.

As is known, increasing the space between the glass panes improves thermal insulation performance, but there is a limit—if exceeded, it can negatively affect thermal transmittance. However, if a third glass pane is added, the performance of the window can be significantly improved.

Additionally, using Warm Edge spacers instead of aluminum ones helps to enhance the thermal insulation performance of the glass and reduces the risk of condensation.
