Although Alberta has been experiencing a milder winter then we have in the past, our prairie weather always has a sneaky way of creeping its cold back in. As winter brings chilly temperatures, it’s common to notice condensation or even frost forming on your home’s interior windows. While this might seem inevitable, there are several steps you can take to reduce or prevent this issue, keeping your windows clear and your home cozy.
Condensation happens naturally when warm, moisture-rich air inside your home comes into contact with a cold window surface. Air can only hold a limited amount of water vapor depending on the temperature. When warm air cools against a chilly window, it loses its ability to hold moisture, causing water droplets to form on the glass. If temperatures are low enough and moisture levels are high, frost can also develop.
To reduce condensation on your windows during colder temperatures, focus on managing indoor humidity levels. Proper ventilation is essential, especially in areas prone to moisture buildup like kitchens and bathrooms. Let natural sunlight warm your windows by keeping curtains and blinds open during the day. If you use a humidifier, adjust it to around 20% to 25% on the coldest days, and consider running a dehumidifier if condensation becomes persistent. Ceiling and exhaust fans are also helpful for circulating air and minimizing moisture buildup—be sure to run them during and after activities like cooking, showering, and cleaning for at least 60 minutes. These simple steps will not only help keep your home comfortable but will also keep your windows frost free until Springtime is here!
