Problems with ventilation
Double-glazed windows are made up of two glass panes that are separated by a spacer bar which serves as an efficient thermal barrier that is filled with air or gas. When the seal fails, moisture can get between the glass panes and cause misting. Misting double glazing isn't just unsightly, it also reduces the efficiency of your home's energy insulation.
There are many reasons why the seal could break down However, the most significant reason is wear and wear and tear. As time passes the seals may weaken due to temperature changes, which cause them to expand and contract. Seals can deteriorate and eventually break down and allow water to get into the window.

Double glazed windows can be affected by humidity. Moisture in the air will condense on any cold surface and this is the case in particular of a glass window. The water will run down the inside of the window and form condensation or fog.
