This allows moisture to get into the window and condense onto the cold glass, which reduces efficiency. This issue can be easily prevented by utilizing extractor fans in damp areas like bathrooms and kitchens and also by opening windows to promote airflow. Dehumidifiers can also be helpful in reducing the amount of moisture. Seals Usually when double glazing turns misty, there is something wrong with the window seals. This could be due to the glass unit itself, or it could be because the windows are getting old and are more prone to issues. In any event, you must be sure to have your windows checked immediately to avoid further damage to the double glazing's insulation properties. The key to the effectiveness of double glazing is the gap between the glass panes that is often filled with an inert gas, such as Argon to improve energy efficiency. This creates a barrier that keeps cold air out and warm air in, which is why double-glazed windows are more efficient than single-glazed windows. However, with time, this seal may be damaged, and when it does, moisture will start to seep in and create a fog-like appearance. This can be rectified in some cases by using a defogging tool which can be purchased at hardware stores or online. The procedure involves drilling into the window an insignificant hole, injecting desiccant that absorbs moisture, and then sealing the hole. However defogging kits are only just a temporary solution and should be repeated as the inert gasses do not replace the original ones lost when the seal came down. Another method to fix the problem is to replace the gasket seal on the frame of the window. It's a simple and inexpensive method to improve the insulation properties of your windows. It is also important to note that it's importan
