Window Condensation and Mold | Innovative Dehumidifiers

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 cause property damage. As stated in the Journal of the Architectural Institute of Korea Structure & Construction, “condensation and mold problems in apartment buildings have been on the rise due to high performance of insulation and air tightness.”¹

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.

**Note** – the moisture-holding capacity of air at *100^oF* (*38 ^oC*) is *10 times* the moisture-holding capacity of air at *30^oF* ¹

Tighter Building Codes

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 wall mounted commercial dehumidifier puts control back in your hands. Designed for everyday use, the IW-25 drains directly into existing plumbing, no more reservoir tanks, to help keep relative humidity below 60 percent, independently of HVAC systems.

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
