Air sealing for casement windows
My 1950’s apartment has a large window. They are about 10 feet long and 4 feet high. There is a fixed center panel and a casement on either end. Single pane, metal frame. The frames are a bit wracked out of square, probably from earthquakes over the years, and won’t close fully. (coastal southern california mild climate but winter nights are in the 40’s with a medium Santa Ana wind ).
basically there’s a variable gap on the casements, anywhere from 1/4″ to almost 1″. Can anyone recommend a decent draft-stopping product/technique? I’d like to also be able to open the windows for those random February 75 degree days, but can live without that. I tried the rolled peel and stick weather stripping, but sizing becomes an issue and the material seems to get beat up by the sun, wind, and dust and wont stay long…
