The sash windows in my 1890s Victorian terrace are very drafty. Not wanting to block air circulation, I've stuck on strip brush insulation strips on the top outside rim of the lower window that meets the frame of the top window. This seems to work well, however, they are too wide for vertical lengths I am loathe to use any kind of frame sealant. Any suggestions much apppreciated
