It could also indicate that the seals on your window units with insulation have deteriorated or broken. Seals It is normal for condensation to develop on the outside of double glazing. This is a sign that your windows work well. It is caused by the air outside warming up faster than your glass, and then reaching its dew point.

The reason for this is that misting up on the inside of your windows typically indicates that there is an issue with the seals, and that water has made its way through the gap between the two glass panes.

A poor window installation could cause misting, since the installer may not have followed the correct fixing methods or fitted the frame and insulation panels correctly. The gap between the two panes of glass in a double-glazed unit is filled with a spacer bar, that creates a thermal barrier as well as insulation. The spacer bar is sprayed with a desiccant that is specially designed, which absorbs moisture and keeps the gap dry.
