But sliding door also let light, smells and sounds through much better. It happens because there are gaps between the door leaf and frame. Besides, to install sliding door you will have to dismantle part of the wall and to put a gypsum plasterboard to mount cassette and sliding mechanism into it.

Folding door is the door consisting of separate sections which move by guide rail set in the door aperture. It can be made of wood, plastic and other materials. Folding doors are used only as interior doors.
