Condensation inside the glass panes however, is a different story. Double glazing that has a misty appearance is more than a nuisance; it can be an indication that the seals on your window unit's insulated seals have broken down or deteriorated. Seals If condensation forms on the outside of your double glazing, this is perfectly normal and is a sign that your windows are operating well. It is due to the air outside heating up faster than your glass, and then reaching its dew point. If your windows are leaking on the inside, this is more of a concern and something you will need to take care of. This is because misting that occurs on the inside of your windows is typically an indication that there is a seal problem and that water is entering the space between two panes. The windows' seals wear down over time because of ageing and wear and tear. They also become damaged if they are exposed to harsh cleaning chemicals, which could cause damage to the material. Poor window installation can also cause misting, since the installer may not have followed the correct fixing techniques or installed the frame and insulation panels properly. The gap between the two panes of glass in a double-glazed unit is filled with a spacer bar, that creates a thermal barrier and provides insulation. The spacer bar is sprayed with a specific desiccant which absorbs moisture and keeps the gap dry. The condensation develops when the spacer bar is damaged or worn-out, and the water in the gap makes its way through the seals. -glazing that is poorly installed and maintained can cause condensation and damp, but it can reduce the energy efficiency of your house. This is because defective windows will let cold air in while letting warm air out, causi
