I can't answer about if it is glued throughout but we changed our carpet out for vinyl in the motorhome we had. We bought the really thick stuff that is meant to just float, although you can use some double sided tape on the edges. It is kind of a pain to put in as a single piece, it is difficult to handle and lay. Looks really nice once in though. Using the thicker stuff is a help to prevent tearing so easily while putting in. I think it is Armstrong that makes it.
