You can reduce moisture by venting moisture-laden air to the outside and by bringing fresh, dry air from the outside into the home. Ventilation is accomplished in many ways. Exhaust fans placed near high sources of humidity, such as bathrooms and kitchens, are used to reduce localized humidity. Some new homes may also have a whole-home ventilation system. In its simplest form, this system consists of a central exhaust fan and a fresh air intake connected to the heating system. The system may be operated by a timer or by a switch located in a central position in the home. A more advanced ventilation system will recapture heat lost in the ventilated air and will have dedicated ventilation ducts in various locations throughout the home. Opening window coverings, even partially, during cold weather is an easy way to reduce condensation. Drapes can restrict air movement near the window which will cause the glass surface to cool, creating the perfect environment for condensation. Heat outlets placed near windows wash the window surface with warm air. This increases the temperature of the window surface and reduces the potential for condensation. Do not deflect the movement of air away from windows or cover outlets with rugs or furniture. Finally, during periods of extreme cold, keep the furnace fan running to maintain a more even heat in the home. Wood flooring manufacturers may recommend a certain humidity level be maintained to prevent warping, cracking and separating of wood flooring components. However, this floor maintenance must be balanced with the need to control window condensation and humidity in cold weather. How can I reduce condensation on my window?
