I have a single pane window. On the interior there is a storm window glass insert. Im getting condensation on the single pane window.. there is none on the interior insert. Does that mean warm humid house air is infiltrating the insert? And if so, would caulking the seems of the insert stop the condensation? Wanted an idea of how to correct this before I goop up the insert with silicon.

I just had all my windows in my house replaced with Pella Designer Series casement windows. Long story short.....the screens for these windows are terrible. They are warped, some retaining clips don't work and the screen wire is not stretched tight. Only three of about the 14 or so screens were made correctly. The local sales rep ordered all new to replace and they came in the same way. Have any of you experienced this with Pella and how did you rectify the problem? Do any of you have an idea how I can contact someone up the ladder at Pella to resolve this? Thanks, Ron
