Why is My Double Glazed Unit Misting Up? When condensation forms on the outside of double glazing it is not an issue and in fact, it is a sign that your windows are working effectively and retaining heat within your home. But when it occurs on the inside of your window panes it is an issue that needs being addressed. Moisture trapped between your windows indicates that the seals have failed – leading to higher heating costs and lower insulation. This can be caused by a variety of reasons. 1.

Typically the condensation appears as a cloudy coating and decreases the transparency of your windows. The misting in double-glazed windows is more serious and is a sign that the seals of the insulating unit are not working properly.

The moisture will then seep into the seals, which causes them to break over time. This can lead to condensation between the glass panes. Another reason for a failed double-glazed unit is that the desiccant in the unit gets saturated. The desiccant sucks up excess moisture and prevents it from getting into the glass panes' gaps. When it is saturated, the desiccant loses its ability to absorb moisture, and the moisture between the panes will grow. The formation of moisture in the gap between the strip of aluminium and the seal is usually the first sign. This is not a simple fix and it is best to replace the whole unit. Utilizing a hairdryer on a regular basis is a great method to remove condensation build up from your windows.
