Why Condensation Forms on Windows

Condensation on windows is a common issue for homeowners in colder climates like Ottawa. When warm indoor air comes into contact with cold glass surfaces, moisture forms on the window.

While occasional condensation is normal, excessive moisture on windows can indicate that the window insulation is no longer performing properly. Older double pane windows may develop seal failures that allow moisture to enter between the panes of glass. When this occurs, the window may appear foggy or cloudy.

Failed window seals also reduce the insulating properties of the glass. This means that heat escapes more easily during winter and outdoor temperatures affect the interior environment more quickly.

Replacing older windows with modern insulated units can help reduce condensation and improve energy efficiency. Many newer windows include argon gas insulation and improved sealing systems that prevent moisture buildup.
