The Mechanisms of Sliding Doors

There are two main types of doors: swing doors and sliding doors. Sliding doors differ in that they move along guides with the help of wheels. They often save space, especially if you use a sliding pocket door. The sliding system is often used in the manufacture of shower doors, folding screens, partitions, and interior doors.

There are also several ways to install sliding doors. The choice of mechanism depends on the client’s desire and on the technical requirements and characteristics of the room.

A door with two guide rails. This mechanism consists of the upper and the lower rail. So the door moves along them. This design is the most reliable and provides good sound and heat insulation. The only drawback of this mechanism is the rail on the floor. It may spoil the appearance of the floor, especially in the case of interior doors.

A door with one guide rail. In such a mechanism the doors are attached only to the upper rail. The lower guide rail is missing. While choosing this type, you have to consider that the wall and the ceiling must be strong enough.  An important advantage of such doors is a quiet movement.

The mechanism of sliding folding doors. This method of door installation is used for harmonica doors and folding screens. Each door leaf is attached to the upper rail only on one side. The other side is bonded to the adjacent leaf of the door. This mechanism allows the screen to slide and fold at the same time. The external door leaf is attached to the floor on one side.
