A communicating doorway has two doors in a single door frame and each door opens away from the other. Communicating doorways are a solution to many design challenges, yet are most commonly used between adjacent hotel rooms. There, the doors can be opened to convert the rooms into a suite, yet guests in either room can close and lock their side. When both are closed, the two doors provide an extra layer of protection against thermal or noise transmission.

If the doors are required to be self closing, you could use two overhead door closers - one on each door. Yet this is often impractical due to space limitations between the two doors. It can also be difficult to install overhead closers in complicated back-to-back configurations or with conflicting closer arms.
