I have seen several articles about replacement windows where it is reccomended to stuff pieces of batt insulation into the widow weight cavity to insulate it. I have heard that this method is unreliable. Would it be better to drill a series of 1" holes in the jamb where it will be covered by the replacement and then fill the cavity with window and door spray foam? My second question is where can I get a reusable spray foam gun that uses the disposable cans of spray foam? Thanks,
