A common reason for failure of a double-glazed unit is when the desiccant within the unit is saturated. The desiccant is designed to suck up excess moisture, preventing it from making its way into the gaps between the glass panes. When it is saturated it loses its ability to absorb moisture, and the moisture between the panes will grow.

Usually, the first indication of this is when you start to notice the formation of moisture on the aluminum strip within the gap. It is important to remember that this isn't an easy fix, and the best option is to replace the entire unit.
