Well guys, I bought a 1907 Queen Anne with wonderfull 6 foot high DH wood windows in various conditions. Windows leak air like you would not believe. Some can actually rattle. Electric baseboard heat. Short term goal is to keep the heat in this winter. Trying that heat shrink palstic inside the windows for now. Long term is to rehab the windows. I want to keep house as close to original as possible (with subtle improvements in sealing and whatnot). If you have some neat weather stripping system I am all ears.
