Moisture Problems – Why Does Condensation Occur on Interior Surfaces?
Condensation on inside of window and condensation on inside of window in cold weather… Condensation can occur on any surface that is below the “dew point” of the air with which it is in contact. The “dew point” is the temperature at which condensation will occur for a given humidity level. In most houses in winter, the inner surfaces of the windows are the coolest surfaces in the home. Condensation will typically appear there before it appears on other surfaces. Condensation is less likely to occur on interior walls, because they are typically warmer than “dew point.” Occasionally however, condensation may occur on cold spots such as nail heads, in corners of outside walls where insulation is reduced, or in confined spaces where the circulation of warm room air is restricted. In extreme cases, condensation may lead to mildew and the growth of mold. What To Do To reduce or eliminate excessive condensation, the humidity level must be decreased and/or the ventilation increased. To reduc
