Double glazed windows are a popular choice for homeowners due to their energy efficiency and sound insulation properties. However, one common problem that can occur with double glazed windows is condensation forming between the panes of glass, leading to a foggy appearance that can be unsightly and difficult to clean. In this article, we’ll explore why double glazed windows fog up and how to get rid of condensation inside them.

Why do double glazed windows fog up?

Condensation forms when warm, moist air comes into contact with a cold surface, such as the glass on a window. In double glazed windows, there is a small gap between the two panes of glass which is filled with a gas, usually argon or krypton. This gap provides an extra layer of insulation, helping to keep the cold air out and the warm air in. However, if there is a problem with the seal around the edge of the window, or if the desiccant (a material that absorbs moisture) inside the window has become saturated, then moisture can enter the gap and cause condensation to form on the inside of the glass.

How to get rid of condensation inside double glazed windows?

If you have condensation inside your double glazed windows, there are several steps you can take to try and resolve the problem.

Check the seal around the edge of the window

If the seal around the edge of the window is damaged or has deteriorated, then it may be letting moisture into the gap between the panes. If you can see any gaps or cracks in the sealant, you may be able to repair it yourself with a sealant gun and some sealant. However, if the damage is more extensive, it may be necessary to call in a professional to replace the seal.

Improve ventilation

Improving ventilation in the affected room can help to reduce the amount of moisture in the air, which in turn can help to reduce condensation on your windows. You can do this by opening windows or using a dehumidifier to extract excess moisture from the air.

Use silica gel packets

Silica gel packets are small sachets containing a material that absorbs moisture. You can place these packets in the gap between the panes of glass to help absorb any excess moisture and reduce the amount of condensation that forms on your windows.

Replace the double glazed unit

If none of the above steps work, it may be necessary to replace the double glazed unit entirely. This will involve removing the old unit and fitting a new one in its place. While this may be more expensive than other options, it will ensure that your windows are once again clear and free from condensation.

In conclusion, while condensation inside double glazed windows can be a frustrating problem, there are steps you can take to try and resolve it. By checking the seal around the edge of the window, improving ventilation, using silica gel packets, or replacing the double glazed unit, you can get rid of condensation inside your windows and enjoy clear, fog-free views once again.
