[Greenbuilding] condensation on storms

[Bob klahn]

Reducing the relative humidity is a standard answer and a necessary 
measure, but  when you say that you "caulk all my windows with removable 
caulk", do that you mean sealing between the jab and the sash?  That is 
suggested  by your mention of removable caulk.

Have you sealed the joints between the trim, casing (and  sill and 
apron, if the windows have these) and the wall surface?  I often find 
these leaking more than the sash/jamb joints.

If these are double-hung windows, how do you seal the meeting rails 
(between the upper and lower sash), another joit where I have found 
overlooked leakage.

It's awkward to speculate on limited information but, if you have 
condensation on the storm panels, you do have leakage.

An inside storm might help, but if the leaks around the inside face of 
the jamb aren't sealed, you would probably still have leakage and 
condensation.

I hope this is helpful and doesn't just re-plow old ground.
