Some kind on insulation has been put in my m8 flat and i could do with it myself for something but i have google "draft excluder" "draft excluder rubber", "windows draft excluder" and never come across the right stuff check b&q, home base screw-fix even fleabay and nothing, so i presume i'm not using the right search term, i only need about 7-8 feet of it
