wet windows

Our windows have large amounts of water condensation which drips onto the sills as well as in the little tray that collects it.
what can we do in our home to help prevent this?
what can we do to our windows to lessen the condensation

This question comes up every year around this time, especially with newer windows with high performance glass. The quick answer is, the humidity level is too high. It should be around 40%, but never higher than 50%. With the old single glazed windows, humidifiers were often used to keep humidity up, since the windows leaked so badly. Tighter windows keep in the comfort and keep out the cold, so you don't need to add moisture to the air for comfort.

If the problem is with older single glass windows, there is not a lot you can do, the glass is cold and the inside air is moist and warm, which equals condensation. Get new windows, you are wasting money on fuel. New tighter windows with hi-performance glass will save 15-30% on fuel, with no other changes.

Humidity is to high! If you are using your heat you need ventilation to remove it. Open a window about an inch or two and turn on your bath fan for a day or two.
