The seal recently broke in the large pane of glass in our otherwise great sliding patio door. Besides a little condensation, are there other problems associated with this broken seal? ("Loss of energy" is what I was told by one person.)Since I will begin my search to replace this door, what should I be looking for to get a simple yet quality door? I do not want to lose my view, so the more glass the better. I am also interested in one of the newer screens that allows you to see better. I would appreciate any advice. Thank you!
