Today, when homeowners wish to upgrade their windows, it is strongly recommended to opt for double glazing. It has even become a compulsory standard as this type of glazing brings many benefits from an acoustic, thermal and security point of view.
Principle of double glazing
Double glazing consists of two panes separated by a zone of air or a gas such as krypton gas. It is the ability of this air layer that will define the quality of your double glazed windows as well as their performance.
Between the windows, a divider in aluminium or synthetic material can be found. It comes to land on the window frame. It is this leap that will eliminate thermal bridges and improve the insulating power of double glazing.
Proven performance of double glazing window systems
Double glazing is the most popular window system currently sold on the market. The best seller models are 16/4/4 and 4/12/4: This means that the double glazing consists of an Assembly of 2 glass of 4 mm thick plates each separated by 12 or 16 mm of air.
The quality of insulation offered by such a system is measured with insulation coefficient referenced under the letter U; If this coefficient is close to zero, then the glass will be more efficient and resistant.
The undeniable advantages of double glazing are therefore a perfect insulation through imprisonment of air from the odourless gas found between the two panes. There is no condensation on the glass, no cold feeling to the touch and a good sound insulation.
