Mist between the glass windows is often caused by a crack in the seal, and it's something that needs to be repaired quickly to prevent mould or damp developing in your property.
Condensation Between the Windows
If you notice condensation forming between your windows, this could be an indication that the sealing in the gas insulating the windows has failed. upvc window repair can be a serious problem that should be addressed as soon as possible particularly in winter, when humidity is at its highest. This could also cause damage to sills, sealant and mould.
Ideally double-glazed windows shouldn't be able to experience condensation between the panes. This problem can be caused by excessive humidity or a particularly cold snap. This issue is usually resolved without the need to replace the entire window. A professional can drill tiny holes in the glass and then spray the inside of the window with a special cleaning solution. The moisture is then sucked out of the window, and an anti-fogger device can be installed to stop any further buildup of moisture in the future.
Condensation can also occur between windows due to air leakage, or other factors outside the window. If this is the case, it will likely take longer for the moisture to accumulate in the window as the air must be warm enough for the water molecules to vaporise. In these situations, it may be better to replace the double glazed windows rather than repair the existing sealed units.
A double-glazed window is constructed consisting of three or two pieces of insulated glass held together by a frame made of metal. The gap between the two of the window is filled with a non-toxic gas for insulation such as argon or krypton and then sealed tightly. The seal blocks the gases that are insulating from escape and also prevents moisture and air from getting into the gap.
As windows age, seals may deteriorate allowing moisture to leak between the glass panes. It is crucial to recognize when seals are beginning to leak because it indicates that the double glazing is no longer performing as well as it did in the past. This could result in a decrease in efficiency in energy use, higher heating bills, property damage, and the risk of condensation forming between the windows.
Mist

The condensation occurs because the air outside is hotter than the glass, and reaches the dew point of the window before the air inside.
