My wife and I bought a 50's vintage home with single pane double-hung
windows. In general, it is very well-built. However, we occasionally get
moisture/condensation on the inside of two of the windows, in two different
rooms on the east side of the house. None of the other windows seem
affected. It happens mostly on more humid days, but sometimes on less humid
days as well.
So...What causes this condensation? What can be done about it? Appreciate
NOTE: The occurrences were on moderate temperature days in which neither the
A/C or heat were even on.
Cndenation happens whe moisture laden air hits a temperature below the dew
point of the air. The glass panes are affected by temperature of the
outdoors, sun, and the indor heat or cooling. The rooms are affected by
excess moisture frm the bathroom, post biling in the kitchen, et.
You cannot chane the laws of physcs, but you can outsmart them. Double pane
widows, storm windows, dehumidfiers will help.
Water vapor condenses when the humidity is high and temperature is low
enough. You can increase the air circulation near the colder windows
(use a fan, pull back draperies, etc), add storm windows, increase the
temperature and/or reduce the humidity. Occasionally we get
condensation with our double-pane windows and I just dry off the
window sills with an old towel as needed.

It depends upon how well your storm windows seal (if you have storm
windows or combo storm/screens). I have a home circa 1910 with double
hung wood windows with no seals at all, but fortunately storm/screens. So
in fall/early winter I may get condensation on inside of storm windows.
But as it gets colder the air becomes drier inside, so it is not an issue
(or is frost instead of moisture).
