Double-glazed windows consist of two panes of glass separated by a layer of air. Double glazing has many benefits over single glazing (where there's just one pane of glass and no air layer). Keeps warm air in, meaning your property is better insulated. This results in fewer draughts and cheaper heating bills. Keeps noise out - you'll hear far less noise from outside with double glazing. Reduces the amount of condensation on the inside of your windows. Heightens security - double glazed glass is more difficult to break than single glazing.

​

In the production of doubleglazing we use a special gas - argon or krypton - between glass and for a special request of a customer we can use triple glaze unit for even better insulation of the noise from outside and for better security.

Argon is the most commonly used gas, due to its excellent thermal performance and cost-efficiency in comparison to other gases. Argon gas reduces heat loss in double glazing by slowing down convection inside the air space. It is extremely cost-efficient, and works well with Low-e coated glazing. Argon and Krypton are colourless, odourless, non-flammable and non-reactive inert gases.
