Hello all. We moved into a 25 year old house in August. Over the wonderfully "warm" Wisconsin winter, we discovered that the patio door leaked cold air like crazy (even with the outer screen and storm sliders). We wanted to get a single swing patio door anyhow (as we had track problems with the old door this summer/fall). I have been looking into brands available locally and would appreciate feedback. The brands we are currently considering (no particular order): Peach Tree, Anderson, Jeld-Wen, and Pella. My father and I will be installing the unit ourselves. Thanks for any feedback!
