Learn 6 Tips To Prevent Condensation On Windows

Window condensation happens when the temperature of the window is cooler than the dew point in the air. When condensation occurs in the summer, it is usually only a visual problem that will go away as the outdoor temperature rises through the morning. However, condensation in the winter can be more problematic as it occurs in relatively low or high humidity and can cause problems such as warping, mold, mildew and wood rot around you window frames.

Use the following tips to help prevent window condensation in the winter:

1. Open your window treatments - Opening the blinds or drapes of your home during the day allows the sun to warm your window to eliminate condensation. You also have the added benefit of passive solar heat gain for your home.
2. Blow warm air on your windows - By blowing warm air across your windows, either with your heating vents under the window or a small heater, you warm the interior of the window which will help prevent condensation.
3. Make sure your home is well vented - Opening all air vents in your home will help to disperse the moist air throughout your home, preventing it from collecting on the windows. When cooking or showering, remember to turn on an exhaust fan to draw the moisture out of the room and reduce the internal moisture in the home.
4. Humidifiers and dehumidifiers - If you are experiencing excess window condensation, turn off the humidifiers in your home and let the air dry out. Similarly, you can use a dehumidifier to dry out the air in your home caused by environmental humidity.
5. Air Infiltration - Inspect your window casing for cracks on the inside and outside of your home because this is how a home get air infiltration which causes condensation. Caulking these areas will close cracks and gaps and prevent condensation caused by air infiltration. If you have excessive areas of need outside the scope of a small DIY project, it may be best to get an energy audit and have professional air sealing performed throughout your home. This will not only prevent condensation caused by air leakage but also improve your home’s comfort level and energy efficiency.
6. Replacement Windows - Replacing your single-pane glass windows with a double or triple-pane glass will reduce condensation because the glass on the inside of the window is a lot warmer than the layer on the outside. When looking at replacement windows, look for windows with low-E coatings as this will increase energy efficiency and reduce the among of radiant heat transfer. This will prevent condensation and make the room more comfortable.
