This is a sign that they are functioning properly. However, condensation within the glass panes is a different issue. Double glazing that is misty is more than just an eye-sore 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 an indication that your windows are working properly. The reason for this is the air outside heating up more quickly than your glass and reaching its dew point. If your windows mist up on the inside, this is a bigger issue and you need to investigate it. This is because misting in the interior of your windows is generally an indication that there is an issue with the seal and that water is getting into the gap between two panes. Window seals break down over time due to ageing and general wear and tear. They also become damaged if they are exposed to harsh cleaning chemicals, which could cause damage to the material. A poor window installation can cause misting because the installer didn't use the correct fixing techniques or fitted the frame or insulated panels correctly. between the two panes of glass in a double-glazed unit is filled with a spacer bar, which acts as a thermal barrier as well as insulation. The spacer bar is covered with a desiccant coating that absorbs moisture and keeps the gap dry. The condensation happens when the spacer bar gets damaged or worn out and the water inside that gap finds its way past the seals. Double-glazing that's poorly installed and maintained can lead to condensation and damp however, it can reduce the energy efficiency of your house.
