Moisture in Double Pain Window

Not all brands of double pane windows are the same. Segi windows have had issues. Ours are Hehr and after 11 years,not one has had a broken seal. If you have it repaired or replaced I'd be sure they warranty thier work.

I know some folks won't go without double pane and some won't have them. It has been our experience and observation that they are a great benefit unless you get a bad brand, then all bets are off.
