Window Condensation : What causes it?

As we all start to give in to the changing temperatures and switch on the heat in our homes, there are some familiar annoyances that reappear.  Window condensation is a top complaint of many homeowners, blocking their beautiful views of the changing fall colors outside.





What causes it?


It is the excess humidity in our homes. Warm air holds more humidity and when comes into contact with the cold surface of the window, it manifests itself in the form of condensation.  The issue is not our windows, it is controlling humidity through ventilation.


How do you prevent it?


1. Run bath fans and kitchen exhaust fans for longer than just showering time or cooking time.

2. Ventilate appliances like your clothes dryer or gas burning stove to the outside.


3. Be sure the louvers venting your attic or crawlspace are open and not blocked.


4. Open the fireplace damper or air out your house for a bit to allow the air full of moisture to escape.



The excess humidity issue




Heating and Ventilating magazine did a study on the sources of water vapor in the home:
- Cooking for a family of four = 4.5 lbs./day
- One shower = .5 lbs.
- Laundry = 30 lbs./wk
- Human occupancy = 6 to 8 lbs./day
- Dishwashing 1.2 lbs./wk
The typical family of 4 easily creates 150 pounds of water vapor a week which is more than 18 gallons of water!
Allowing this air to normalize itself is the key to preventing many moisture issues within the home, come learn more at our workshop next week with Cindy Ojczyk, who specializes in the science behind beauty:
