Replacing Double Glazed Windows

Modern double glazing offers a variety of advantages, including noise reduction, UV protection and property security thanks to multipoint locking mechanisms.

What should you do if your double-glazed is showing signs of wear?

1. Excessive Condensation

In the winter, when windows and doors are closed, condensation may form inside the glass panes if the air temperature is warmer than the window's surface. This is a natural occurrence that can be prevented by opening windows, improving ventilation more generally, running a dehumidifier and keeping moisture levels low with extractor fans. However, if condensation forms regularly on the interior of your windows this is a sign that the double glazing has failed and it needs replacing as soon as possible.

In contrast, condensation on the outside of your windows is a common phenomenon and indicates that your double glazing unit is performing exactly as it should. The condensation that forms outside your windows during the morning is due to the temperature of the cold glass dropping below the dewpoint of the surrounding air. This causes the water vapour in the air to be drawn into the window where it condenses. This can be made worse by plants that create excessive moisture in your home and also by high levels of humidity.

If you notice condensation appearing inside your double glazing this is a much more serious issue. It is an indication that the seal between the two glass panes has been broken, allowing warm air from your house to find its way in while the gas that is used to insulate it is lost. This could cause serious damage to the double glazing and should it not be addressed will greatly impact the cost of energy.
