Double glazing

How to choose this product

Double glazing consists of two panes of glass separated by a hermetically sealed layer of air or inert gas, such as argon or krypton. Since a single pane of glass conducts heat well, double glazing serves to reduce thermal transfer. The space between the panes must remain dry, since water also conducts heat well. Thus, a desiccant is incorporated into the spacers between the panes.

While pane thickness has little influence on heat conduction, it does affect the window's acoustic insulation properties. Some double-glazed windows use glass with a layer of metal oxides, which reflects solar and heating radiation, reducing its conductivity.


Double glazing is found in windows, entry doors and building facades.
