Why is My Double Glazed Window Misted?

Double glazing is a fantastic way to improve the efficiency of your property and secure optimal energy efficiency. If you notice that your windows are misting this could be an indication that the seal on your window has broken.

This will allow moisture into the insulation area of your windows, which can reduce their performance dramatically. This problem is easy to solve.

What is it?

You may see condensation on the exterior of your double-glazed windows at times particularly when it's cold and windy. This is a typical indication that your double glazed windows are securing the cold, but letting in heat. You can clean it up or let it go by itself.

This is more likely to happen if your double-glazed window mists inside. This could be an indication of a broken seal or malfunction in your double glazing. If a double-glazed sealed unit breaks down, or fails, moisture may get in between the two glass panes of your window. The argon, xenon and krypton gasses that are used in these units can also leak out. Once this happens, the high density gases lose their insulation properties and your window is not sealed anymore.

One of the main reasons for the seal of a window to wear out is normal wear and tear that occurs over the years. The constant expansion and contraction of your double-glazed windows are caused by temperature changes. Cleaning with chemicals that are abrasive on your double glazed windows can also cause damage to the seal, and cause it to break over time.

If the seal of your double-glazed windows has failed warm air can escape between the glass panes, and cool air can get in, causing moisture buildup on the spacer bars within the misty glass unit. This is commonly referred to as a 'blown window' and could result in costly energy bills throughout the winter.

Replacing the glass units of the double-glazed windows you have can solve this problem. This is a more cost-effective alternative than replacing the entire window. It can also guarantee that your home will be adequately sealed and insulated. You should also ensure whether the company that is replacing your double-glazed windows is insured. This will safeguard you in the event of unexpected issues.

What is the reason for this?

Understanding the reason for condensation is essential to understand how much does it cost to replace misted double glazing to best deal with it. Condensation is caused by the temperature of the glass is below the dew point - the point at which the water vapour in the air becomes liquid water. It is therefore common to see it at late at night or in the early morning when the dewpoint is high and the temperature of the air is higher than the glass's surface.

Condensation inside double-glazed windows will be more frequent as the weather becomes colder and humidity levels increase. It is generally a natural phenomenon and does not necessarily mean that your double glazing has a problem. If the condensation is visible from the outside of your window and disappears as the sun rises then there is no reason to be concerned about it.

Double-glazed windows that have been damaged or faulty will not insulate as well as they should, which could result in higher costs. If the seals are damaged then moisture could pass through the two glass panes and eventually cause the misting effect.

The causes of the problems that lead to misted double glazing are numerous but there are some main reasons worth checking for:

When you see condensation on the inside of your window, this is usually the first indication that something is wrong. The next stage will be when you begin to observe water stains or damage to the glass that could be caused by moisture that is trapped between the two panes of glass. This could be caused by the installation process or simply wear and wear and tear. This could indicate that your window is coming to the end of its life and needs to be replaced to enhance the insulation performance of your home.
