Window Condensation Prevention
If you're troubled during the winter by condensation on the windows of your home, you aren’t alone. Window condensation is a common problem in cold climates.
If you're experiencing condensation on the surface of your windows, that doesn't indicate that they're defective but rather, conditions may have created that cause a “dew point.” Simply put, the dew point is the temperature at which the water vapor in the air becomes saturated and condensation begins on solid surfaces. Condensation forms on interior glass surfaces when there’s too much moisture in the air. According to Andersen Windows + Doors, recommended humidity levels in winter months should not exceed 30-35 percent.
There are several ways in which you can help reduce the interior humidity in your home; they include checking your ventilation, using a dehumidifier, opening blinds and curtians during the day, leaving ceiling fans on, and using an exhaust fan in the bathroom.
