I don?t know if this called something special but all I can seem to find is the stuff that goes at the bottom of your door or the stuff that is foam based and I don?t want that, this is the kind of stuff you use for internal doors, I live near a screwfix, B&Q, Tool Station and a Selco but I can?t seem to see this kind of thing on those sites, mind you I am just searching for ?draft excluders?.
