This becomes more noticeable in the Autumn and Spring during Seasonal temperature changes, when moisture within the double glazed unit condenses on the inside of the double glazed units, creating small water droplets giving the impression that the glass has misted up. The main reason for a sealed glazed unit to break down is time, weather and the environment.
Over time, the wind, sun, frost and everyday environmental conditions forces the sealed unit to constantly expand and contract acting like a small pump slowing sucking in and then releasing air from between the glass panes.
The air entering the space in this way will contain the natural moisture in the air. Eventually the dessicant or silica gel (material designed to absorb the moisture that is contained within the spacer bar between the glass) becomes saturated, therefore cannot draw any more moisture from the air within the glass unit.
The result is condensation between the panes and the start of the deterioration of the insulation and vision properties of your double glazing units.
The longer that this is left before replacing the glass units, the more impaired your vision will be throughout the the glazing units.
