Best weather stripping for swing open bay/bow window.
Hi all I decided just to keep my 40 y/o bow window and replace the rotten wood since it would be over $4k to replace. I need to add some weatherstripping to the windows. What type is best and how do you install it. I am thinking the rolls of adhessive foam strips and put that on the areas where the windows make contact with the stops. Should I stick it on the base or the Window? Is that the best type?

the window might have some shallow grooves cut into the frame around the edge. look for them. if so, it was designed to use a vinyl extrusion, an O with a ribbed edge. that is a compressible weatherstrip with the ribbed edge pushing into that groove to hold it in place.

in that case, go with the OEM weatherstrip, it will not deteriorate and will last longer. the big threat is if the window is opened and closed in freezing weather, which can pull the ribbed edge out of the frame.

this is in the weatherstrip area of all better home centers.

I don't think it ever had any weatherstipping. It just has wood against wood and two locks clamp it shut.

Try at Caldwells furniture and door store, you can get a replacement window and doors, cheap yet reliable. I have been their clients for years and so far those second hand items I bought from them are still in good condition today. They are known sometimes as back doors bay area shop along Bay Area, San Francisco, check them at]

Dennis and 3M make vinyl "v" strip weatherstripping that should do well. in the olden days of yore, when men were men and gnarled oak branches meant for firewood were scared, two strips of brass served the same purpose. you cut to fit, position the strip so it points out with the glue strip ready to bond to the fixed wood surface. peel the strip and press-glue the strip. then bend it in half along the fold to form the V, and shut the window on it.

The best weatherstripping would be a replacement kit available from the original bow manufacturer.
