Have you ever wondered why condensation forms on your windows and what you can do to prevent this from happening?

Window condensation occurs through a combination of the moisture in the air and the temperature. Often, window condensation is nothing to be concerned about as it occurs naturally when extreme temperature differences exist between the interior and exterior of your home or if the air outside the home is very moist. Glass is a water barrier, so when humid or extreme weather conditions exist, window condensation  naturally occurs.


People commonly blame the window for condensation build up, but most often the buildup of window condensation results  from  high humidity in your home. Humidity can build up as a result of several activities in your home such as showers, dishwashers, washing machines, humidifiers and even breathing. In fact, a family of four can add as much as a quart of moisture to the air per hour!


When Should I Be Concerned About Window Condensation?

In mild cases, there should be little cause for concern about condensation on windows. But constant and heavy condensation could cause damage to wooden window frames, walls or more, and you should take steps to mitigate the moisture in your home.


The easiest way to reduce moisture is to use exhaust vents in your bathrooms, kitchens and clothes dryer whenever you use these areas. You can also prevent window condensation by installing energy efficient windows in your home. Energy efficient windows will help insulate your windows from drastic temperature swings that cause window condensation to form in the first place.


The greatest area of concern should be if you see window condensation form between panes of glass on a double or triple pane window. If this occurs in your home, it means that your window’s seal is broken and the window needs to be replaced.

Window condensation due to a broken seal indicates that your window has lost much of its energy efficiency qualities and the window should be replaced. Double and triple pane windows have air sealed chambers that help insulate your home from outside conditions, but when this seal breaks, it diminishes the energy efficiency of the window – making condensation more likely and increasing your energy costs.
