When the days are shorter and jackets are thicker, winter has arrived. As temperatures drop, the dew point will follow, leaving “watermarks” on your window. Condensation not only makes windows foggy but can also cause property damage and mold growth.

Condensation will form on surfaces when the air has an excess of moisture. The temperature directly affects the amount of moisture air can hold before saturation. Once air becomes saturated condensation will take place. The ability of air to hold water vapor increases as it warms and decreases as it cools. Once air has reached its dew point the moisture that the air can no longer hold condenses on the first cold surface it encounters, like magic, drops of condensation form.
During colder months, indoor air is much warmer and holds more moisture than outdoor air. When warm and humid indoor air makes contact with the cooler windows, the moisture condenses on glass.

As building codes become tighter moisture generated inside does not have a way to escape. Too much moisture creates damp window frames and walls, which can lead to mold. In order to stop window condensation reduce the amount of moisture in the air. Moisture control can make your home more energy-efficient, reduce heating and cooling expenses, improve comfort and prevent mold growth.
The IW25 In-Wall dehumidifier puts control back in your hands by removing up to 25 pints of moisture a day. Designed for everyday use, the IW-25 drains directly into existing plumbing, no more reservoir tanks, to keep relative humidity below 60 percent. The hands-free IW-25 allows you to take control of moisture to prevent condensation and mold growth.
Signs Condensation is a Problem
- Your home feels damp: Relative Humidity should be maintained between 30% and 50% 2
- Discoloration of walls/ peeling wallpaper: caused by lack of ventilation and excess moisture
- Musty smell associated with mold becomes noticeable: caused by the release of microbial volatile organic compounds 3
- Warped wooden surfaces: occurs when moisture levels of wood change unevenly
