This is a sign that they are functioning properly. However, condensation within the glass panes is a different issue. Double glazing that has a misty appearance is more than a nuisance It could be a sign that the seals on your window unit's insulated seals have broken down or deteriorated. Seals It is normal for condensation to develop on the outside of double glazing. This is a sign that your windows are working properly. This is due to the air outside reaching its dewpoint faster than the glass. If your windows are leaking on the inside it is a greater concern and you should investigate it. This is because misting in the interior of your windows is typically an indication that there is a leak in the seal and water is leaking into the gap between the two panes. Window seals degrade over time due to ageing and general wear and tear. They also degrade when exposed to harsh cleaning chemicals which can damage the material. Poor window installation may also cause misting due to the fact that the installer did not use the correct fixing methods or fitted the frame or insulated panels correctly. A spacer bar is used to fill the gap between two panes of windows with double glazing. This creates a thermal barrier and also acts as an insulation. The spacer bar is sprayed with a desiccant that is specially designed, which absorbs moisture and keeps the gap dry. The condensation happens when the spacer bar gets damaged or worn out and the water inside the gap gets over the seals. Poorly installed and poorly maintained double-glazing isn't just a source of condensation and damp, it can also damage the efficiency of your home. The windows that are not properly installed let cold air in and warm air to exit, which means you will need to spend more money heating your home. If you
