Condensation Between the Windows
If you notice condensation appearing between your windows, it is an indication that the sealing in the gas insulating the windows has failed. This is a serious issue that must be dealt with immediately, particularly in winter, when humidity levels are at their highest. It could also cause damage to the sills, sealant and mould.
Double-glazed windows shouldn't be able to have condensation between the panes. However, it is not unusual to have high humidity or an extremely cold snap to cause this issue. Fortunately, this issue is repaired without replacing the entire window. A professional can make tiny holes in the window and spray a special cleaning solution inside. The water is then drained from the window and an anti-fogger is fitted to stop the build-up of moisture in the future.
Condensation between the windows can be caused by air leakage or other causes outside the window. If this is the scenario, it's likely to take longer for moisture to gather in the window as the air has to be warm enough for the water molecules to vaporise.

A double-glazed glass window is comprised of two or more pieces of insulated tempered glass that are joined by a metal frame.
