Why is My Double Glazed Window Misted? Double glazing is a fantastic way to improve the efficiency of your home and ensure optimal energy efficiency. However, if you notice your windows misting then it's usually an indication of a broken window seal. This allows moisture into the insulation portion of your windows, which can decrease their performance drastically. Luckily, this problem is fairly simple to fix. What is it? It's possible to get condensation on double-glazed windows, particularly when it's extremely cold and cold and windy. This is a normal sign that your windows are working well, keeping cold out and the warmth in. You can clean it off or let it go on its own. If your double-glazed window is leaking on the inside this is a bigger problem. This could be a sign of a broken seal or failure in your double glazing. When a double glazed seal unit breaks down or fails, moisture can get in between the two glass panes of your window. The argon, xenon, or krypton gases that are used in these units may also escape. Once this occurs the high-density gasses lose their insulation properties, and your window no longer functions as an enclosed unit. Natural wear and tear is one of the main causes for the seals to fail on windows. The constant expansion and contraction of your double-glazed windows is caused by changes in temperature. Double glazing seals are susceptible to damage by using abrasive chemicals on them. If the seal of the double-glazed windows you have is broken warm air can escape between the glass panes, and cool air can enter and cause moisture to build up on the spacer bars inside the glass unit. This is often referred to as a 'blown' window and it can result in expensive energy bills throughout the winter. Replacing the glass units in your double-glazed windows could solve this issue. It's a less expensive alternative than replacing the entire window. It also guarantees that your home will be properly insulated and sealed.

In extreme cases, black mould can even grow on window frames and cills which can be harmful to you or your family. Understanding the cause of condensation is vital to know how to best deal with it. Condensation occurs by the temperature of the glass is below the dew point - the point at which the water vapour in the air becomes liquid water.

As the weather turns colder and the humidity levels increase condensation inside double glazed windows is more likely to occur because it forms much faster. In the majority of cases, it's a natural phenomenon and does not indicate any issue with the double glazing. If the condensation appears only on the outside of the window and disappears once the sun comes up, there is no reason to worry. Double-glazed damaged or broken windows will not effectively insulate your home as they should, and this can result in higher energy costs. If the seals are damaged then moisture could pass through the two glass panes and will eventually cause an effect of mist.

The next stage will be when you start to notice water stained or damaged glass that could be caused by the trapped moisture between the two panes of glass. This could be due to damage caused during installation or just gradual wear and tear over time. In some cases, this may be a sign that the window has reached the end of its life and requires replacement to improve the insulation efficiency of your home. How do I get rid of it?
