Condensation Between the Windows
If condensation appears between your windows, this is an indication that the sealing in the insulating gases has failed.

It could cause damage to the sills, sealant, and even mildew or mould.

Double-glazed windows shouldn't have condensation between the panes. This could be caused by excessive humidity or a particularly cold snap. This problem is usually resolvable without the need to replace an entire window.

The water is then sucked out of the window and an anti-fogger system can be added to prevent further accumulation of moisture in the future.
Condensation between the windows can be caused by air leakage or other causes outside the window.

As the windows age, the seals will deteriorate and can allow moisture to leak into the gap between the glass panes. If the seals begin to leak it is crucial to be aware of this since it signifies that the double glazing no longer performs the way it did in the past. This could lead to lower energy efficiency, increased heating costs, damage to the property and the risk of condensation forming between windows.
