Why is My Double Glazed Unit Misting Up?

When condensation appears on the outside of double glazing, it is not a problem and in fact, it is a sign that your windows are functioning correctly and keeping heat in your home. If it appears on the inside of window panes it's a sign of an issue.

Usually condensation appears as a cloudy film and decreases the transparency of your window.

This leads to condensation between the glass panes.

Another reason for a failure of a double glazed unit is that the desiccant within the unit is saturated. The desiccant sucks up excess moisture and stops it from leaking into the gap between glass panes. But, when it becomes over saturated the desiccant begins to lose its capacity to absorb water and eventually, the moisture between glass will increase, leading to the mist that is frequently seen.

The formation of moisture in the gap between the aluminium strip and the seal is usually the first indication. It is important to remember that this is not an easy fix and the best solution is to replace the entire unit.
