This lets moisture seep into the glass that is cold, reducing the efficiency and appearance. This problem can be easily prevented by using extractor fans in damp rooms such as kitchens and bathrooms, and also by opening windows to promote airflow. Dehumidifiers can also be helpful in reducing moisture. Seals Usually when double glazing turns blurred, there is something wrong with the window seals. It could be due to the glass unit itself, or it could simply be that the windows are getting old and have become more prone to problems. In either case, you should have the windows checked promptly in order to avoid further damage to the double glazing's insulation properties. The space between the two glass panes is filled up with Argon or a similar inert gas to improve energy efficiency. This arrangement creates an insulation barrier that keeps warm air in and cold air out, and is one of the main reasons why double glazed windows are more efficient than single-glazing. However, with time, this seal could fail, and when it does, moisture will start to seep in and cause a foggy appearance. This can be rectified in certain situations by using the defogging kit that is available in hardware stores or on the internet. The procedure involves drilling a small hole in the window, then injecting an inert gas that absorbs moisture, then sealing the hole. However defogging kits are only an ineffective solution and will need to be repeated since the inert gasses do not replace the original ones that were lost when the seal came down. Another way to fix the issue is to replace the gasket seal around the frame of the window. This can be done relatively inexpensively and easily and is an effective way to improve the insulating properties of the windows. It is also important to note that it's essential to use quality
