Why is My Double Glazed Window Misted?
Double glazing is a great method to boost the efficiency of your home and ensure optimal energy efficiency. However, if you notice that your windows are misting, it is an indication of a damaged window seal.
This will allow moisture into the insulation section of your windows, which can cause a drastic decrease in performance. Luckily, this issue is quite easy to resolve.
What is it?
There may be condensation on the exterior of your double-glazed windows at times especially when it's cold and windy. This is a indication that your double-glazed windows are blocking out the cold but also letting in warmth. You can clean it off or let it go by itself.
This is more likely to happen If your double-glazed windows leaks inside. This is usually a sign that the seal on your double glazing has deteriorated, or 'failed' as it is known in the industry. The moisture can get inside the two panes of glass in double-glazed units that have failed. The argon, xenon and krypton gasses that are employed in these units could also escape. When this happens, the high density gases lose their insulating properties and your window not sealed anymore.
One of the main reasons for a window's seal to fail is the natural wear and tear over years. The constant expansion and contraction of your double-glazed windows is caused by temperature fluctuations. Using abrasive chemical cleaners on your double glazed windows can also damage the seal and lead to it failing over time too.
If the seal of your double-glazed windows is damaged warm air can escape through the glass panes and cool air can enter, causing moisture buildup on the spacer bars inside the glass unit. This is often referred to as a 'blown window' and can result in expensive energy bills throughout the winter.
This issue can be resolved by replacing the glass units within your double-glazed windows. It's a less expensive alternative than replacing the entire window.

Understanding the cause of condensation is essential to understand how to handle it. Condensation occurs when the surface temperature of a glass is below the dewpoint, the temperature at which the water vapour from the air turns into liquid water. It is therefore common to observe it at late at night or in the early morning, when the dewpoint is highest and air temperature is higher than the glass surface.
Condensation inside double-glazed windows will be more frequent as the temperature drops and humidity levels rise. It is generally a natural phenomenon and does not necessarily mean that your double glazed windows are in problems. If the condensation is visible from the outside of your window and disappears once the sun rises, there is no reason to be concerned about it.
Double-glazed windows that are damaged or defective will not insulate as well as they should, which can lead to higher bills. If the seals are broken, moisture could get in between the two panes and cause an evaporation.
The causes that lead to misted double glazing are many but there are some main reasons worth checking out for:
The first indication of a problem with double-glazed windows is usually when you begin to see condensation appearing on the inside of the window. Water stains or glass damage caused by the trapped moisture between the two panes could be the next sign. This could be due to damage during installation or just gradual wear and tear as time passes. In some cases, this may be an indication that the window is reaching the end of its lifespan and requires replacement to improve the insulation efficiency of your home.
