All but two of my windows are new replacements, and the two older ones get condensation/ice on the INSIDE of the storms. I'm assuming heat is escaping the old windows and condensating on the storm window. This is also in the kitchen and cooking seems to make matters worse. Any suggestions on what to do. I assume I just need to figure out a way to keep the heat in but I want to make sure that's what's causing the condensation first.
