What Causes Ice on Windows?

Ice on windows is a common concern, particularly during extreme cold temperatures. This phenomenon is the result of condensation – where warm, humid air meets the cooler surface of your windows, leading to moisture accumulation. The issue will be far more common and severe with older, aluminum frame windows, but during extreme cold snaps, even newer windows can be affected.

If you've noticed this issue with your new vinyl windows, fear not—there are practical steps you can take to address and minimize the condensation that leads to this ice.

The Causes of Condensation

Several factors can contribute to the appearance of condensation on your windows, such as…

High Humidity Levels

Elevated indoor humidity increases the likelihood of condensation. Everyday activities like cooking, bathing, and even the presence of numerous houseplants can contribute to higher humidity levels.

Temperature Variations

Rapid temperature changes, especially during colder seasons, create conditions favourable to condensation. Understanding and managing these fluctuations is crucial to addressing the issue.

Addressing Condensation

To tackle condensation on your windows, consider implementing the following proactive steps:

Ventilation

Inadequate ventilation traps moist air indoors, fostering condensation. Proper ventilation is key to maintaining a balanced indoor environment and preventing moisture buildup. Ensure proper ventilation by using exhaust fans during activities that generate moisture, such as cooking and showering. A dehumidifier can also be a valuable tool in controlling indoor humidity levels during the cold winter months when ice is likely to occur.

Air Circulation

Promoting air circulation can be as easy as allowing some space between furniture and windows. This prevents the formation of stagnant air pockets that contribute to condensation.

Temperature Management

Maintain a consistent indoor temperature to minimize the temperature differential between the indoor air and window surfaces. Adjust your thermostat appropriately to create a more balanced environment.
