Folding doors stack panels to one side to open a room completely. Both systems hang the panels from the top track for smooth folding. Each folding profile belongs to a complete door profile family — NICE door profiles are universal profiles: the same frames build eight door types, so swing, sliding, hanging and folding doors in one project share one sightline and one finish.
