What Causes Windows to Fog Up?

Foggy windows are a common issue many homeowners face. As your trusted provider of window and door replacement services, Renewal by Andersen® of Rapid City provides an overview of what causes this to happen and what you can do about it.

Temperature

One of the main reasons behind window fogging is the difference in temperature between indoor and outdoor environments. When the warm air inside your home comes into contact with the cold glass surface, it cools down and loses its ability to hold moisture. As a result, the excess moisture forms condensation on your windows. To prevent this, make sure your home is well insulated and maintain a more consistent temperature inside your living space. 

Humidity

The higher the humidity level is inside your home, the more likely your windows will accumulate condensation. Several activities in your home can contribute to high levels of humidity, such as cooking, showering, and even simply breathing. Proper ventilation is critical to reducing window fogging caused by high moisture levels. Opening the exhaust fans in your kitchen or bathroom helps lower moisture in the indoor air.

Inefficient Windows

Older windows can often contribute to the fogging issue, as they’re less likely to be as energy-efficient as their modern counterparts. They are also prone to issues, including damaged window seals, which allow moisture to seep through and increase the chances of mold growth. Outdoor air can also enter through the gaps created by the damaged seals, affecting your home’s indoor comfort. Upgrading to new, energy-efficient windows can minimize temperature fluctuations inside your home and help prevent the formation of condensation.
