How Do I Eliminate Window Condensation in My Home?
If you recently replaced your windows and you're noticing more condensation you probably replaced your old windows because they were drafty. Slight gaps and cracks around the sashes and frames allowed air to travel freely between the outside and inside. This air movement actually prevented condensation in two ways. Primarily, the warm moist air was able to escape from the house without resting on a cold surface. Secondly, enough cold air was allowed to enter the home to create a thick blanket of cold air across the window. This layer was thick enough to prevent the warm moist air from touching the cold window surface.
Energy Efficient Replacement Windows
Your new windows improve the energy efficiency of your home, lower your energy bills, and add to your comfort by blocking air movement through your windows. Blocking this movement however may raise the humidity levels in your home causing condensation. Condensation is created from high indoor humidity and low outdoor temperatures. Since we cannot control the outside temperature, our only hope of curing or eliminating condensation is to control the indoor humidity.
In today’s modern building and construction, we continually search for a “tighter” home that retains our winter heat and summer cooling. Vapor barriers, high performance doors and windows, tile, and plastic wall coverings all conspire to keep whatever air is inside...inside. By building an energy efficient home, we create other problems that may need special attention. One of these problems is the control of moisture (humidity) in the air. The “tighter” the home, the less likely moisture will escape.
