Traditional swing doors are not always good decision. When opening for such a model, you need to leave a fairly decent area unoccupied. But sliding doors on rails and rollers do not take up any space when opened.
Sliding folding door mechanism
Sliding system mechanism
There are several options interior doors of this kind, but the principle of movement remains largely the same. Its essence is to ensure not opening, but displacement of the sash along the wall or the second sash. In this case, the area near the doorway remains free, and the doorway remains open.
Bottom guide sliding doors
To achieve this effect, a special mechanism is used. Along the movement of the door leaf, a profile is fixed to the floor, wall or ceiling special type– guides or rails. Rollers are installed on the door itself. When opening, the rollers move along the guide, and the sash moves to the side.
Sliding doors with glass inserts
There are 2 types of such a system.
- Floor-mounted - the door leaf is inserted into two guides - upper and lower. The main rollers in the lower part of the blade ensure movement along the lower guide, the upper rollers move along the upper rail, holding the blade in a strictly vertical position. This option is very reliable and durable.
- The suspension system assumes the absence of a bottom guide. In this case, the rollers are fixed only in the upper part of the product. When opened, the rollers move along the top rail, simultaneously providing both movement and retention in a vertical position. The option is more effective and more suitable for interior doors: the lower guide forms an unpleasant threshold, and in this case it is missing.
Hanging sliding door system
However, the hanging system requires reinforced fittings, so it is not suitable for doors made of heavy materials - solid wood, glass, for example. In the photo - doors on rails in Leroy Merlin.

Types of interior doors
In Russia, a solution of this kind is extremely popular, so you can find products that are optimal in cost and quality not only in specialized stores, but also in large hypermarkets, for example, Leroy Merlin. There are always several dozen different models in the catalog.

But before choosing a product by color or shape, you need to decide on the type of interior door and the opening principle, and they are different.
- Sliding doors - 1 or 2, the most famous option in Russia. This is a classic model - hanging or floor-standing, made in all possible styles. The guides can be installed both on the wall and on the opening or even on the ceiling, and the material used for manufacturing is very different - from chipboard to glass.
Sliding interior doors differ from the option for a sliding wardrobe in the principle of convergence.
The doors do not fit one behind the other, but are joined in the center of the doorway, so that only one rail is fixed to the floor.
- Cassette - the sash moves according to the same principle, but moves not along the wall, but inside it. More often this is not a recess in the main wall, but a false panel that is mounted on the outside of the wall. The solution looks very elegant. Doors can be either single-leaf or double-leaf.
- Folding - the mechanism of interior doors on rails and rollers of this kind is different. When opened, the sash folds at least twice and then moves to the side of the opening. In this case, it blocks part of the opening, but practically does not occupy the area of the room. The rollers are attached only to the top of the product in the center of each part of the sash. They move along the upper guide, the lower one is missing. Folding of the leaf is ensured by ordinary door hinges.
The key to quiet and smooth operation of sliding interior doors is high-quality fittings. Roller structures have a complex structure and require the use of an expanded set of elements.
The set includes:
- guides. As a rule, modern door systems are hinged. Large and heavy sliding panels often equipped with a floor rail. Guides are made of steel and aluminum;
- rollers equipped with bearings. Elements often have a rubberized shell for soft movement;
- components for rotary models. The functioning of these original products provides a rotating mechanism;
- pencil cases. Metal constructions built into the wall, only the sash remains visible;
- special handles.
The main criterion is the weight of the sashes. For heavy sliding doors made of solid wood or glass, it is better to purchase reinforced rollers. Also pay attention to the following nuances:
- the rail should be twice as long as the interior panel;
- the floor track should ideally have a seal that prevents clogging;
- aluminum profile is quieter than steel;
- the number of accessories is selected based on the size and number of sections.
You can evaluate the entire range in person in the showroom in Moscow.
To ensure that the interior door does not swing, but slides to the side, various mechanisms with guides for sliding doors are used. Let's understand how these systems work.
Before planning which mechanism you will use when installing sliding sashes, you need to decide on the type of structure itself. They can have one flap that slides to the side or several. They may be moving in the general direction, or at least one leaf will move in the opposite direction. Particularly interesting are designs of 4 or more parts, and they can move apart not only along their plane, but also fold like an accordion, which creates completely new ideas for using space.
So, the simplest type is exactly what was described in the first example, that is, one-, two-, three- or even four-leaf doors. The first option, when opening, moves freely along the guides, usually to the right, but the 2 doors diverge to the sides, like in an elevator or in a subway car. If the door has 3 parts, the 2 outermost ones are on the same level and move apart in opposite directions, and the 3rd one covers one of the leaves, moving in the same direction as it. And finally, the 4 parts are divided into 2 pairs, each of which moves opposite to the other, and one panel overlaps the second when opened. Another type is the same two-, three- and four-leaf doors, but of the cascade type. Their main difference is that all the doors move only in one direction.
One- and double doors They can be moved either along the wall, covering part of it in the open position, or buried in it, going into special grooves.
Sliding interior doors
The next option is compartment doors, when two doors, converging when closing the opening, do not close, but, moving along two parallel guides, slightly overlap their edges. In this case, if the opening is sufficiently wide, 1 part can be stationary, and the second can move freely along the guides. In essence, the previously discussed three-leaf version can be made as a coupe if the middle, third part, closing the opening, slightly overlaps the edge of the panel moving towards it along parallel runners.
Next comes the radius sliding door. To make such a structure, you need to have a rounded wall instead of one of the corners and an opening in this area. Otherwise, except for bending along a certain radius, the doors are not much different from ordinary sliding ones. In the open position, they will overlap small sections of the wall on the sides of the opening, and in the closed position, they will close together, like in an elevator. Accordingly, the single-leaf version simply slides to the side along the guides. In some cases, radius doors can be buried in special grooves if the wall is thick enough or the niche is made of plasterboard.
And finally, the last type is accordion sliding doors. Doors of this type are equipped with rollers sliding along the top edge on special turning platforms. The panels themselves are connected to each other by ordinary or piano hinges, several pieces each, depending on whether such structures are made in the form of one or two “curtains”. It is noteworthy that the width of the sashes can be different, for example: narrower at the edges, and wider closer to the middle of the opening. The number of panels in each group is practically unlimited, except for the distance between the side ends of the interior opening.
Having chosen the one you like with the doors sliding to the sides, you need to carefully consider all the mechanisms available today that are included in the sets of sliding systems (SRS).
There are relatively few of them, and the simplest type is suspended. In fact, this is only one guide along which the rollers move, but it is very powerful and can withstand heavy loads. A groove is made at the bottom of the door leaf into which a ridge stop placed on the threshold fits so that the door does not swing when moving. However, if the groove does not allow it to move from side to side, then it can quite warp slightly in its plane, due to the relatively free position of the rollers inside the guide.
Hanging view of a sliding door structure
Unlike not very reliable (albeit inexpensive) suspension systems, which quickly become unusable during active use, KRS with two guides are much more durable. This option provides for each sash of the structure a lower groove in which an additional roller moves, which also serves as a stop. As a rule, such mechanisms are installed on compartment doors and accordions.
It should be taken into account that the presence of bearings in the rollers increases their service life and increases the smooth movement of the panel. The number of wheels is also of considerable importance; for panels with a large weight, 4 rollers are required in each carriage.
So we've covered everything possible options, which you can install in your home with your own hands. However, now you need to correctly combine sliding systems for interior doors and the type of preferred design.
As already mentioned, compartment and accordion doors require lower guides. Moreover, the first option requires a separate gutter for each panel and a separate suspension system, respectively, while with an accordion the mechanism moves exclusively in one plane. Conventional sliding doors work on the same principle, and you can make them hanging for savings and ease of assembly with your own hands.
Bottom accordion guides
Radius sliding structures are much more interesting. Of course, their mechanism is no different, but all the carriages are rotated in relation to each other in an arched guide. Such a design must have a support roller and, preferably, more than one, so that the sash does not jam during sudden movement.
Glass doors also have some special features if they do not have wood, metal or plastic frame. When mounting rollers directly to thin glass, special overhead slats with rollers in the upper part are used; they are screwed along the entire length through small holes. At the bottom, instead of a roller or stop, a narrow guide groove is sometimes installed.
How to properly install a sliding system with your own hands
How to install a sliding door system with your own hands - step-by-step diagram
Step 1: Marking
First of all, you need to take into account that even for the simplest suspension mechanism former door frame does not fit, and therefore the jambs will need to be dismantled. Only when you have an empty opening left can you make markings under new design. Stock up for the future decorative panels for masking the top guide and platbands for finishing the ends of the opening.
Now we measure the height of the sash and add 15 millimeters to the result obtained for the lower gap. We measure the required distance along the wall from the floor and make marks along which we draw a line, after which we place the door next to it, wedging it from below with wedges, and check the correctness of the calculation.
Step 2: Install the Guide
We measure the width of the already assembled mechanism (you need to check it in action to make sure there are no defects). Then we add the width of the guides and mark the locations of the fasteners, focusing along the line of the top edge of the door panel. We disassemble the mechanism for further assembly already on the sash. If there is only one top rail, you can fix it with your own hands on a pre-attached one to the wall. wooden beam. If there should be 2 or more hanging profiles for rollers, then special brackets are installed, screwed to the wall with several long screws.
Hanging the door
And finally, the most crucial moment - in the lower part of the door you need to either make a groove with your own hands, if a stop knife (comb) or a leash will pass there, or secure a plate with a lower roller. The latter needs a special gutter, which is mounted on the line of movement of the door and acts as a threshold; to install it, use a plumb line or laser level so that the sash does not become distorted. Now all that remains is to hang the door on the mechanism, securing the previously installed hinges using a special adjusting screw, which allows you to more accurately set the height of the door relative to the floor.
When assembling such a system with your own hands, special attention should be paid at the very beginning to aligning it with the level of the guide so that there is no tilt towards the opening of the sash. Otherwise, we can confidently predict that the door will open on its own, and the load lock will quickly fail. IN as a last resort, you can make a slight tilt towards closing, then the sash will always strive to close, but the small tilt angle (no more than 2 degrees) will not allow it to do this quickly. If you make synchronously sliding doors with your own hands, do not forget to adjust the cable to final assembly systems.

What sizes of door leaves are there?
Taking measurements to order a future sliding design, it is necessary to take into account that the size of the door leaf should be 10 cm larger than the dimensions of the opening where it will be installed. This will ensure there are no gaps and create maximum effect privacy.
The standard sizes available for serial sliding doors on rails and rollers manufactured in Russia are 600 mm, 700 mm, 800 mm, 900 mm.
If the opening where the structure is supposed to be installed is larger, you can use two or more canvases instead of one - depending on whether the customer simply wants to block the opening or delimit the room into several separate spaces. Classic option is a product consisting of one or two canvases.
