I can try leaving them slightly open this winter, but don't
know how much this will increase heat loss. It may be worth it
if this would work. We just spent the time washing all the
windows, to get as much sunlight in the house as possible this
winter, and this will be a wasted effort of condensation is
bad.would be a waste of time because of the condensation. </div>

The thing to remember about condensation is, that when air at a
given dew point (relative humidity) contacts a surface with a
temperature less than that dew point, condensation *will* occur.
Cures for this fall into two categories, lowering the dew point of
the air, and increasing the temperature of the surface.<br>
<br>
If one is getting condensation on the exterior storms, then warm
moist air from inside is getting through the window (or surrounding
trimwork) to reach the storm, and that should be one's first
priority. Leaving the storms open will be close to not having them
at all (not recommended).<br>
<br>
I generally recommend interior storm windows to supplement that
insulation value of the windows (adding about R-2), and to act as
another air barrier. You can learn how to make them for yourself
from my website, or I am now producing kits shipped anywhere in
North America. Those in Maine can attend one of my workshops, and
also get completed windows. See:
