How To Beat Your Boss On Double Glazed Window Misted

Why is My Double Glazed Window Misted?

Double glazing is an excellent way to improve the efficiency of your home and secure optimal energy efficiency. However, if you notice that your windows are misting, then it's usually an indication of a damaged window seal.

This will allow moisture into the insulation section of your windows and cause a drastic decrease in performance. This is a simple issue to solve.

What is it?

It's possible to get condensation on double-glazed windows, especially if it is very cold and cold and windy. This is a indication that your double glazed windows are blocking out the cold but also letting in warmth. It can be easily cleaned off, or let it clear by itself.

If your double-glazed window has a tendency to mist on the inside though, this is a more serious issue. This is usually a sign that the seal on your double glazing has failed, or 'failed' as it is referred to in the field. Moisture may get in between the two panes of glass in a double-glazed unit that has failed. This can cause the argon, xenon, or krypton gas that is used in the windows to leak out as well. When this happens, the high density gases lose their insulating properties and your window is not sealed anymore.

Natural wear and tear is among the main reasons that cause seals to fail on windows. This is due to the constant expansion and contraction of the gasses inside your double glazed windows as temperatures rise and fall. Double glazing seals can be damaged using abrasive chemicals on them.

If the seal of your double-glazed windows has failed the warm air could escape between the glass panes and cool air could enter and cause moisture to build up on the bars that hold the glass unit. This is known as a "blown" window and could lead to expensive energy bills during the winter.

Replacing the glass units in your double-glazed windows could solve this problem. This is a much more cost-effective solution than replacing the entire window and it can ensure that your home is insulated and sealed. It's also a good idea to ensure that the company you choose to replace your double glazed windows is insured since this will protect you in the event of any unexpected issues regarding the installation.

Why is this happening?

Understanding the reason for condensation is essential to understand how to best deal with it. Condensation occurs when the temperature of a glass falls below the dewpoint - the temperature at which the water vapour from the air changes 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's surface.

Condensation within double-glazed windows is likely to become more frequent as the temperature drops and humidity levels rise. In the majority cases it is a natural occurrence and doesn't indicate an issue with the double glazing. If the condensation appears only on the outside of the window and disappears when the sun comes up there is no reason to worry.

Faulty or damaged double glazed windows won't provide the insulation as they ought to and this could result in more expensive energy bills. If the seals are broken then moisture can pass through the two glass panes and eventually cause an effect of mist.

The causes that cause misted double glazing are many but there are some main reasons worth checking for:

The first sign of a problem with double-glazed windows is typically when you start to see condensation appearing on the inside of the window. The next stage will be when you notice water stained or damaged glass that could be caused by trapped moisture between the two panes of glass. This could be due to damage during installation or simply wear and tear. In some instances this will be a sign that the window is reaching the end of its life and is in need of replacement to improve the insulation efficiency of your home.

How do I get rid of it?

Double glazing is a great investment in the energy efficiency of your home and the appearance of your windows. However, if your double glazing is misty or cloudy it can spoil the look of your windows. The solution to this problem is easy and affordable. Double glazing that has mist is a result of condensation or moisture entering the space between the double-glazed windows which must be airtight. This is typically a sign that your window seal is broken and requires repair.

It is common for double glazed windows to have condensation on the outside, particularly in cold weather. This happens when the glass is chilled by the air that has reached its dewpoint. This water vapour will become visible once it reaches the cold surfaces on your windows. It will disappear once the glass warms back up.

It is usually only when double-glazed windows get smoky that you need to take action. This is because the condensation is signalling that there is a problem to the seal between the two panes of glass in your window and could be a sign of poor installation or chemical used in cleaning products.

To get rid of condensation on your double-glazed windows, there are several options you can consider. You can wipe them clean with a damp cloth to get rid of the condensation. You can spray them with a glass cleaning solution that is specifically designed to eliminate the haze caused by condensation. You can also use dehumidifiers at home to take in moisture and prevent it from getting into windows.

There are professional steps that can be used to fix your double glazed window mist. This involves drilling a small hole into one of the windows and pumping into a desiccant that is specially designed, which will aid in drying out the window and avoid any further issues. This can be dangerous and should only be carried out by a professional. This procedure will restore your double glazed windows to their original condition and will help to ensure that you don't face problems with condensation or misting in the future.

What is the best option?

It is normal for double-glazed windows to develop condensation on the exterior surface of the glass panes. This is a sign that windows are operating efficiently and can be easily removed. The condensation is due to the temperature difference between air inside the home and the glass surface.

If you notice condensation between the panes of glass in your double glazing, it is not normal and should be addressed immediately. The window seal is damaged and moisture may enter the gap between the glass panes. This can result in windows losing their insulation properties, which will reduce the energy efficiency of your home.

The most effective way to minimize condensation on double-glazed windows is to improve the ventilation inside your home. Opening the windows on a daily basis can help lower humidity levels and allow fresh air to circulate through your home. It is recommended to make use of extractor fans in areas that generate lots of moisture such as kitchens and bathrooms. Dehumidifiers can also be useful in actively taking excess moisture out of the air and keeping it from condensing onto cold surfaces, such as windows.

Cleaning the glass of your windows with anti-fogging products is an additional way to reduce condensation in double-glazed windows. These products are available in most hardware stores. They are designed to stop the build-up of moisture. However it is important to note that these solutions aren't permanent and could need to be reapplied regularly.


If your double glazed windows are still under warranty, the most effective way to solve a problem with misting is to get in touch with a professional installer. It is recommended to go with a FENSA licensed company since they will provide a 10 year guarantee and will abide by UK Building Regulations.
