Double misting of the glazing is a issue that can affect modern windows and doors. It happens when the seal fails and moisture enters the space between the two panes of glass. This could be condensation or fogging, and will not just affect the appearance of your window, but also affect its performance.

Double-glazed units comprise two glass panes sealed hermetically with a gap between them. The gap is typically filled with argon or air to increase insulation. The seal on the glass will last the lifetime of the window. However the age of the windows, the way they were initially installed and the cleaning products used to clean them can influence the lifespan of the unit. In most cases the sealed unit will fail because air enters the gap between the glass panes. This will cause water to get into the gap and create condensation.

A common problem is misting between glass panes in windows that are double-glazed. It happens when the air gets warmer faster than the glass and causes it to reach its dew point and form water on the spacer bar inside the window. This moisture can then leak out of the window, causing fogging or misty effects. The humidity can also cause the glass to fog up which may block the view and make the windows less effective.
The reason this issue is due to a leak in the seal between the two glass panes of double glazing. This could be due to many factors, including age and the way in which the windows were installed originally. Sealants do not last forever and wear out with time.
