Seem fine winter and summer. There is a failure of logic here somewhere. Windows from factory are filled with dry air or a heavy gas like Argon. The seal is nearly 100%. No condensation is observed. A small leak develops and at some point, condensation is observed. A slightly larger leak is installed and the condensation goes away, permanently? I find it hard to believe that condensation can't happen still. It's not like the very slow leak would concentrate the water vapor inside the panes. It simply acts as a low pass filter giving a DC value of the signal with the AC component largely removed. The hole in the glass changes the time constant allowing the water vapor to leave, but only very slowly. When temperature changes more rapidly condensation will continue to form. > Seems to me like a vented 2-pane window is less prone to condensation > than a single-pane. Less heat conduction to drive condensation. There was enough heat conduction to condense inside the window before the hole was drilled. Drilling the hole will only impact the RC time constant of the water vapor levels inside the window. The heat conduction is not related to your issue. The inside of the outer pane will be colder than the inside of a single pane glass. So if there is water vapor inside the window it will condense. -- Rick C
