We had Cardinal vinyl windows installed in Sept. 2002. The problem in condensation. The condensation occurs on the screen frame and on the outside where the window sash touches the frame,(where the weatherstrip is located). There is no condensation on the glass or no condensation inside. All the condensation is outside. When the weather drops below freezing this condensation freezes and then is difficult to open the window. Not that I want to open it in the winter, but may need to for safety reasons. Our inside humidity is about 30%.The windows were insulated and caulked around the frame when installed. Is this normal condensation or are the windows leaking warm air? Thanks for any help.

Try removing a screen and see what happens.

I think that you windows are leaking around the sashes and when the warm air hits the the aluminum frames of the screens, it freezes.

Good luck and post back to let us know,

I removed the screens. This did not help. The windows are vinyl.The moisture occurs on the outside window frame where the window sash touches it(the part of the frame that the window slides up and down on). This is hard to explain. I talked to the manufacturer and they say this is normal. Condensation occurs when warm and cold air meet. I feel if condensation is occuring on the outside then warm air has to be leaking out past the weatherstrip and hitting the cold air. Is it possible that warm air can leak through the vinyl and not the weatherstrip and this could be causing the condensation? The condensation on the frame is right where the weatherstrip has contact with the frame. Any help or suggestions are apreciated. Thank you.
