Window Seals VS Air Infiltration
Hello People, I have the Double-Pane WALLSIDE WINDOWS ... Installed in 1991. Just 5 years ago, I noticed some fogging/moisture in the Middle Largest Window apx. 5'x 5' of the Three window set. This moisture runs vertical near the outer edges, that butt up against the two outer lights. The outer light pannels do open up for fresh air, and have a sealed edge. I Don't feel any air movement through the seals on a windy day.
I am not quite sure where the problem is. All Help in Solving this Mystery, Will be Greatly Appreciated. Thanks, Nitrojc.
