Condensation or fogging between the panes is usually a sign that the seal holding the glass panes together has deteriorated. This can be fixed with the reseal.
Seals
Seals are a crucial component of double glazing because they increase the efficiency of energy and insulation of windows. They are located between the glass panes and uPVC frames, they create a vital airtight barrier which helps keep out rain, wind, drafts, and condensation which can cause damp on windowsills and walls. Window seals can also help to keep warm and cold air from each other, which can reduce heating costs.
It is not common for window seals to develop defects. This usually happens due to exposure to extreme weather conditions and elements like high winds, snow and rain. However, it can also be the result of improper installation or the use of chemicals, such as paint strippers, which can damage the rubber.
If the window seals fail, moisture and humidity could seep through the glass panes causing fogging or misting. Double glazing may lose its insulating properties when the inert gasses between the panes is no longer present.

Locks
