Linvisibile's Hinged door is available also in Curved leaf version. It is distinguished by the use of adjustable concealed hinges and the absence of door frames or jambs to achieve seamless continuity between wall and door.
It can be painted in the same finish as the walls, becoming almost invisible. Or the door structure can be left visible, with only the panel forming part of the design continuum and the panel finish, to create special atmospheres, in a tasteful way.
