Harmoses doors have recently been not very popular and not in demand. Now they are used quite often, from a part due to the original design, as well as in connection with some other positive characteristics of such doors.
These doors differ from others not only by the opening mechanism, but also by the method of the door leaf.
The main advantage of all folding and sliding doors and harmonica doors is no exception is their economy, in terms of the area of the premises. In general, the origin of the modern design of the farm doors comes from conventional screens, which are also folded when opening and are also laid out when closing.
Of course, hut doors are used exclusively as interior doors. By the way, the harmonica doors have advantages not only over swinging, but even before sliding doors. The fact is that they are not shifted and thereby do not leave the plane of the doorway, which means they do not soak, then where the canvases of the sliding doors are shifted. That is, we can say that the doors of the accordion are the most compact door structures. But at the same time, one cannot but mention that they differ in the worst indicators in heat and sound insulation, among all types of door structures.
