Hanging door mechanism. Interroom doors on rails. How to install a sliding door system with your own hands - step by step diagram

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 extended set of elements.

The set includes:

  • guides. As a rule, modern door systems are hinged. Large and heavy sliding canvases often equipped with a floor rail. Guides are made of steel and aluminum;
  • rollers equipped with bearings. Elements often have a rubberized shell for softness of movement;
  • accessories for rotary models. The functioning of these original products provides a swivel mechanism;
  • pencil cases. Metal structures are built into the wall, only the sash remains in sight;
  • special handles.

The main criterion is the weight of the wings. 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 canvas;
  • 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 personally evaluate the entire range in the showroom in Moscow.

Construction of doors on rails

How does the mechanism of interior sliding doors on rails and rollers work?

The principle of operation of the sliding mechanism door structures quite simple, and the canvas itself moves absolutely silently. The video below clearly demonstrates what such a door consists of, how it works and how it is installed.

Advantages and disadvantages of doors on guide rails

Advantages:

  • space saving;
  • easily and silently opens;
  • gives the room an original look;
  • versatility - suitable for any opening;
  • ease of installation;
  • not damaged when hitting a wall;
  • does not slam shut suddenly due to a draft;
  • the possibility of zoning a large room.

Flaws:

  • poor smell and sound insulation;
  • the possibility of foreign objects getting into the rails, due to which the canvas may stall;
  • high cost of services of professional installers;
  • quick failure in the presence of installation errors.

Where are doors on rails most commonly used?

Most often, these designs are used in houses with narrow corridors because they do not require additional space. They are also desirable in houses whose owners follow the current trends of our time.

They are also used in shopping malls, entertainment facilities, oriental restaurants, commercial facilities.




5. Corridor

What are the door leaf sizes?

When taking measurements to order a future sliding structure, it must be taken into account that the door leaf should be 10 cm larger than the size of the opening where it will be installed. This will ensure there are no gaps and create maximum effect privacy.

The standard dimensions that serial sliding doors on rails and rollers made in Russia have are 600 mm, 700 mm, 800 mm, 900 mm.

If the opening where the installation of the structure is supposed to be is larger, two canvases or more can be used instead of one, depending on whether the customer wants to simply block the opening or delimit the room into several separate spaces. Classic option is a product consisting of one or two canvases.

Interior sliding doors are a great opportunity to update the interior. Combining functionality and modern design, such doors will become an unusual element of your house. However, in order to choose not only beautiful, but also secure door, especially close attention should be paid to the mechanism.

Interroom sliding wooden doors.

Sliding doors consist of several parts. Most often this is a canvas, a fastening system and a mechanism. All necessary details sold as a set and included in the price of the door. However, in case of any breakdown, having no idea how the door works, you will have to turn to specialists, and this is an extra waste of money.

Let's try to figure it out on our own, how the mechanism works and whether it is possible to independently assemble interior sliding doors. This will help us with instructions and photos that can be easily found on the Internet.

The basis of the mechanism

The mechanism for sliding interior doors is quite simple and consists of three main parts:

  • profile guides (rails);
  • roller device;
  • bracket mount;
  • stoppers;
  • screws.

Profile guides are made of metal - often aluminum, sometimes steel. There are doors with one rail and with two, and with a single rail, it is attached only from above. The length of the rail should be twice as long as the doorway.

Sliding mechanism.

The sliding door is equipped with two rails - from below and from above. The double rail design has its advantages and disadvantages:

  1. The mechanism with two rails is more stable.
  2. As a result of the main load on the lower component, the mechanism with two rails can withstand heavy loads and has a longer service life (especially with a heavy door leaf).
  3. The best indicators of sound and noise insulation.
  4. The bottom rail forms a threshold through which you can stumble.
  5. Over time, dust and dirt get clogged into the bottom rail, making cleaning difficult.

The upper rail is involved in the smooth movement of the door, while the lower one is used as a support. But there are sliding doors, the fastening mechanism of which provides for only one rail - the top one. Such doors are called suspended, and are most popular.

Suspended sliding doors without bottom rail.

If you decide to install just this type of door, then make sure that the quality of the top rail is the highest, otherwise the rail may sag under the weight of the leaf. When installing, you must strictly follow the instructions and photos. Lasting metallic profile and reliable fittings are the key to a successful purchase of a slider, or a door on wheels.

The roller device ensures easy sliding of the door along the rail. To choose the right roller mechanism for sliding interior doors, you should pay attention to the presence of a lower rail, the weight of the leaf and its size. If the door is equipped with a bottom rail, the rollers are installed closer to the corners at the bottom and at the top in the middle. The rollers are covered with wear-resistant rubber. They use bearings that make it possible for the door to slide silently when opened. Due to the protection against dust, the bearings have long term operation.

Most often, the rollers are attached only to the canvas, however, the design of the sliding door provides for their attachment to the box, and outwardly such a mechanism looks like a groove.

Hanging doors with several leafs are equipped with a different device - rollers connect the leaf and the frame using a hinged lever.

This mechanism makes it possible to build closed door panels in one plane.

Stoppers serve as door movement limiters, at the same time fixing and holding it.

It is worth paying attention to the fittings: it looks unusual. Sliding interior doors, due to their design, cannot be equipped with conventional handles, because they will interfere with the movement of the canvases. In such doors, handles are used in a recess that do not protrude beyond the width of the leaf. If not interior doors are used, but entrance doors, then special locks and closers are attached to the mechanism.

When ordering a sliding door, an instruction with a description of the mechanism, an assembly diagram and a photo will be attached to it.

Description of a typical device

After description general principles work of all incoming parts, we give a typical description of the mechanism sliding doors. It should contain the following parameters:

  • Minimum door thickness.
  • The material from which the rollers are made.
  • The method of fastening the plates (from the corner, or in the middle).
  • The presence or absence of a latch, with which latch and profile it is placed.
  • Features of the structure of some parts, for example, some models are equipped with a built-in hinge for adjusting the position of the door. Such mechanisms are useful in uneven walls, they allow you to achieve a strictly vertical position of the canvas.
  • The list of accessories (for example: the sliding door mechanism kit includes 4 steel carriages (chrome-plated steel) with rollers on ball bearings, a lower leash, a fixing kit and 2 clamps.
  • Thus, it is easy to check the integrity of the door set.

    Schematic of the sliding door mechanism.

    Self-assembly

    Create unique interior apartments and increase the usable area of ​​the apartment easily. For this there are sliding interior doors. Do-it-yourself installation will save you money.

    It will require an understanding of the process of the mechanism and a small set of tools.

    After purchasing a sliding door with everything you need in the kit, you can proceed with its installation. To do this, we do the following:

    1. We make the markup that will be needed for the guides. To do this, measure the height from the floor to the door with a tape measure. Do not forget to add 15-20 mm to the obtained indicator for the space between the floor and the door, plus the height of the profile rails and the assembled mechanism.
    2. Make some marks on the wall and connect them with a line.
    3. There is another way to measure the height of the guides, but it is not so accurate. To do this, you need to attach a door leaf to the opening, marks are placed along the upper edge, and the parameters of the mechanism and guide are added to them.
    4. Before mounting the guides, make sure that the drawn line is strictly horizontal. The easiest way to do this is with a level. Thus, you protect yourself from annoying mistakes and the need to redo work.
    5. Now we proceed to install the guide, and we mount it so that the line is on top. The fastening method depends on the type of rail. Some models offer wall mounting with dowels, some are mounted on brackets or timber. Fasten the rail not close to the wall, but at a small distance from it, so that when the door is opened, the doorway does not interfere.
    6. Important note: the length of the rail must be twice the length of the doorway, otherwise the first time you open the door, it will simply fly off the rail. When calculating the length, add a few more centimeters of spare travel.
    7. Now you need to insert a mounting bolt inside the carriage and determine the entire resulting mechanism inside the rail. An ordinary single-leaf door requires only two rollers, while compartment doors or "accordion" doors must be equipped with rollers according to the number of movable leaves.
    8. Install the brackets for the carriages at the top of the door with a gap of 3-6 mm from the edge. This method of fastening is permissible for any canvas, except for glass. Glass doors fastened with special screw clamps. Also, given the weight of the glass, any door made of this material supported from below by the second rail.
    9. After installing the roller mechanism and fasteners, it is time to install the door leaf in place. To do this, carefully lift it up and screw the bolts into the brackets. To make work easier this stage requires assistants to secure the doors evenly and effortlessly.
    10. If the sliding doors are installed evenly, it remains to decorate the doorway and slopes. If debugging is required, it can be done using bolts.

    Because of his unusual design Sliding doors require certain types of hardware.

    Now it remains only to put the accessories. A self-made door will help you better understand its mechanism and make sure of the quality of installation.

    To ensure that the interior sash is not hinged, but moves to the side, various mechanisms are used with guides for sliding doors. Let's see how these systems work.

    Before planning which mechanism you will use when installing sliding sashes, you need to decide on the type of construction itself. They can be with one sash moving to the side or with several. They can be moving in a common direction, or at least one leaf will move in the opposite direction. Of particular interest are designs of 4 or more parts, and they can move apart not only along their plane, but also folding 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, opening, moves freely along the guides, as a rule, to the right, but 2 wings diverge to the sides, as in an elevator or in a subway car. If the door has 3 parts, the 2 extreme ones are on the same level and move in opposite directions, and the 3rd overlaps one of the leaves, moving in the same direction as it. And finally, 4 parts are divided into 2 pairs, each of which moves opposite to the other, with one panel overlapping the second when opened. Another type is the same two-, three- and four-leaf doors, but already of a cascade type. The main difference between them is that all of their doors move only in one direction.

    Single and double doors they can move both along the wall, closing part of it in the open position, and sink into it, going into special grooves.

    Sliding interior doors

    The next option is compartment doors, when 2 wings, converging when closing the opening, do not close, but, moving along two parallel guides, slightly overlap the edges. In this case, with a sufficient width of the opening, 1 part can be fixed, and the second can move freely along the guides. In essence, the previously considered three-leaf version can be made as a compartment, if the middle, third part, closing the opening, slightly overlaps the edge of the panel moving towards the parallel skids.

    Next comes the radial sliding door. To make such a design, you need to have a wall rounding instead of one of the corners and an opening in this area. In all other respects, except for bending along a certain radius, the sashes are not much different from ordinary moving 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, like in an elevator. Accordingly, the single-leaf version simply moves to the side along the guides. In some cases, radius doors can be buried in special grooves if the wall is thick enough, or a drywall niche is made.

    And, finally, the last type - doors sliding apart with an accordion. Shutters of this type are equipped with rollers sliding along the upper edge on special turntables. The panels themselves are interconnected by ordinary or piano hinges, several pieces, depending on whether such structures are made in the form of one or two "curtains". It is noteworthy that the width of the wings 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 leaves moving off 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 hanging. In fact, this is only one guide along which the rollers move, but it is very powerful, capable of withstanding a large load. At the bottom, a groove is made in the door leaf, which includes a ridge stop laid on the threshold so that the sash does not sway when moving. However, if the groove does not allow it to move from side to side, then it can completely warp in its plane, due to the relatively free position of the rollers inside the guide.

    Hanging view of a sliding door structure

    In contrast to not very reliable (albeit inexpensive) suspension systems, which quickly become unusable during active operation, it is much more durable than a KRS with two guides. This option provides for each sash of the structure a lower chute in which an additional roller moves, which simultaneously serves as a stop. As a rule, such mechanisms are installed on compartment doors and accordions.

    At the same time, it should be taken into account that the presence of bearings in the rollers increases their service life and increases the smoothness of the panel movement. 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 that 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, coupe and accordion doors require lower guides. In this case, the first option needs a separate chute for each panel and a separate suspension system, respectively, while the accordion mechanism moves exclusively in one plane. Ordinary sliding doors work on the same principle, and you can make them suspended for economy and ease of assembly with your own hands.

    Bottom rails

    Radius sliding structures are much more interesting. Of course, they do not differ in anything special, but all the carriages are deployed in relation to each other in an arcuate guide. Such a design must necessarily have a support roller and, preferably, not one, so that the sash does not jam during a sharp movement.

    Glass doors also have some features if they do not have wooden, metal or plastic frame. When mounting the rollers directly to thin glass, special overhead rails with rollers in the upper part are used, they are screwed along the entire length through small holes. In the lower part, instead of a roller or stop, a narrow guide chute is sometimes placed.

    How to 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: Markup

    First of all, it must be borne in mind that even for the simplest suspension mechanism, the old door frame is not suitable, and therefore the jambs will need to be dismantled without fail. Only when you have an empty opening left, you can mark up under new design. Stock up for the future decorative panels for masking the upper guide and platbands for finishing the ends of the opening.

    Now we measure the height of the sash and add 15 millimeters to the bottom gap to the result. We measure the required distance along the wall from the floor and make marks along which we draw a line, after which we put the door next to it, knocking it out with wedges from below, and check the correctness of the calculation.

    Step 2: Installing the rail

    We measure the width of the already assembled mechanism (you need to check it in action to make sure that there is no marriage). Then we add the width of the guides and mark the location of the fasteners, being guided by the line of passage of the upper 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 to the wall wooden beam. If the hinged profiles for the rollers should be from 2 or more, then special brackets are installed, screwed to the wall with several long screws.

    door hanging

    And, finally, the most crucial moment - at the bottom of the door you need to either make a groove with your own hands, if there is a stop knife (comb) or a leash, or fix the plate with the bottom 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 skew. Now it remains only to hang the door on the mechanism, securing the previously installed hinges with a special adjusting screw, which allows you to more accurately set the height of the sash relative to the floor.

    When assembling such a system with your own hands, special attention should be paid at the very beginning to leveling the guide so that there is no inclination towards the opening of the sash. Otherwise, it can be predicted with confidence that the door will open by itself, and the load latch will quickly fail. IN last resort, you can make a slight tilt towards closing, then the sash will always tend to close, but a small angle of inclination (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.

    Sliding doors are a very convenient and compact design, which is perfect not only for dividing interior space, but also for zoning rooms. It's universal modern version which is very popular. When choosing sliding doors, it is important to know what mechanisms they have and how they work.

    Kinds

    Sliding interior doors, depending on their design, are divided into certain types. So, there are:

    Rail with a different number of wings

    These can be structures with a rail at the top or bottom, there can also be two-rail models. The most popular are products on one upper rail. They look very elegant and unusual. These doors can be either single or double doors. It all depends on the width of the passage in which they are installed.

    Radius

    These doors are quite unusual and completely transform the interior of any room. They are quite massive. All such designs have the shape of a semicircle. Typically, they are made from tempered glass at least 8 mm thick. This design also assumes the presence of a rail mechanism. This type of door is perfect for zoning.

    "Harmonic"

    These are models that fold sideways and each sash is assembled in a zigzag pattern. Each section of such a door is superimposed on each other in turn and the door folds very compactly. The design looks very light and usually has bright design. They can be installed in any passages.

    Rollback

    Such a mechanism assumes that when the door moves, the leaf moves inward and to the side. This type of door is a sliding door. In this case, on the wall adjacent to the entrance there is special frame, in which the sash is located at the moment when you open the door. In addition, such models may have specially designated places in the wall in which this structure is hidden.

    Combined

    Principle of operation

    Most models have mechanisms with guides. The door leaf is usually presented in the form of one or two leaves, but there are also models with a large number of leaves. The canvas moves along the guides located above and below on special rollers. So, there are models with a single-track type of movement, in which the lower guides are completely absent, and the canvas moves along the top.

    Two-track type - when the door moves along the bottom rail, and it is held on top by a stop to ensure an ideal vertical position. Such a principle of operation have structures with a large weight.

    The principle of movement of the sash can be different. She can move along the wall, as if superimposed on it. The second option is to move inside the wall. It would be correct to say that door leaves hide not inside the wall, but inside the cassette located there.

    Another option is overlapping movement, when one movable sash overlaps the main deaf, standing without movement. This option is the simplest, but not very convenient, it is completely unsuitable for narrow aisles.

    Design options and their characteristics

    Door designs can be varied. So, there are the following types:

    Synchronous

    This option is different in that it allows you to open two doors at the same time. In this case, the door leaf is divided in two and opens in different directions along the wall. As a rule, lighter materials are used for this, since in general the design will not withstand a heavy door leaf. The design includes rollers, guides, a cable, a hook, as well as special fixtures for fasteners. This is a rather complicated, but generally reliable mechanism. It will be quite difficult to install such a door on your own, so installation is most often trusted only by professionals.

    Telescopic

    This design option is suitable for mounting if sliding system includes at least two doors. As a rule, these are two or three doors, which move in one direction when opened. The doors are fixed with a special synchronizer and are placed not on one rail, but on two different, parallel ones. Thus, the sashes also move apart synchronously, but one main sash pulls all subsequent ones. This design is fixed either at the top doorway, or at the bottom with an aluminum profile. It is along them that the sashes move with the help of support carriages.

    As a rule, rubberized rollers are used in this design, which allow the structure to move very smoothly and silently.

    Invisible

    This is a very convenient hidden type mechanism that hides behind a specially designed false panel. In another way, this design is called compartment. For its installation, a threshold is not used. This mechanism is fixed on the top of the door.

    A feature of the invisible mechanism is that its installation is possible only if initially during construction a place was provided for it inside the wall.

    If the thickness of the wall is not enough to hide sliding doors in it, then a special pencil case can be used for this. Thus, this indicator can be increased by the size of the pencil case. An invisible mechanism is used only if the door is not glass. Such a door leaf in this case is unacceptable to use.

    Suspension

    Such a mechanism is otherwise called Standard. It is a construction without a threshold, which also does not have a bottom rail. The door slides only along the top rail. The structure itself is of an open type and moves to the side along the wall. Hanging doors of a sliding type can be easily installed by hand.

    barn

    The mechanism of this type is most often made of steel. This design is of an open type and includes a steel guide, rollers and a door leaf. This mechanism is most often purchased for fairly spacious aisles. The barn mechanism differs in noiselessness and smoothness of the course. As a rule, this quality is provided by reliable bearings. Often this mechanism is supplemented with a special closer.

    Tram

    This design option has rollers not from below, but from above. That is, the guides are most often located on top, and the door structure is attached to them with the help of special elements and moves along it with the help of special rollers that roll only along the upper part of this skid. This mechanism is perfect for decorating an apartment or house in a retro style.

    shut-off

    Such a sliding design implies the presence of additional fittings in the form of a lock or a lock mask. The latch or lock is mounted in the locking mechanism, which will be triggered at the moment the lever is pressed. The locking mechanism may be different. For this, buttons are often used, which at one moment are able to block the movement of the door. So you can close it and lock it or open it and fix it in a position convenient for you. The locking mechanism is installed in any door leafs. Such designs can be with a latch, turnkey or magnetic.

    Sliding systems

    There are also various variations of extension systems.

    coplanar

    Such a system assumes the presence of a separate skid for each door leaf. Thus, when you open this structure, each half runs over and the other on top of it. Most often in this case, models with two door leafs are used. But if there are three canvases, then the sliding system becomes three-sliding.

    An alternative option for a coplanar extension system is to install the central section on a separate skid, and the two extreme ones on one common one. Thus, it will not be possible to open two sections at once, since two door leaves located on the same skid will not allow this to be done. When closed, they have a stepped design. open type. One part of the guide will always be visible.

    Door leafs are installed in individual skids more often than in common ones. This option is suitable for both three door canvases. This way, when the doors close, they line up and close the rails. For this, the extension system is supplemented with special brackets with a running mechanism. Such a door is somewhat reminiscent of a compartment, but when opened, the canvas shifts slightly forward and to the side, which is different from a compartment door. Closing the door, the canvases are put in place and the ladder system becomes invisible.

    The coplanar sliding system is different in that it is a combination of several types of mechanism at once.

    This is a very comfortable and versatile design.

    Fast

    This is a system whose mechanism is based on supports. It does not have a frame and it also needs guides. As a rule, these can be single or double structures. Both metal and plastic are used as a material for guides of this type of sliding systems. But the guides themselves are usually very narrow, so they save space in the room. To install such a door, milling is not required.

    Ghost, or hidden

    This design and all door fittings are completely closed from prying eyes. The guides are not visible either above or below the opening. Most often, it is still located on top, but is very inconspicuous, thereby expanding the space. There are very convenient hidden models in which the guides are not located in door frame but directly inside the door. Thus, only the mount and rollers are mounted on the wall. So the sliding system becomes completely invisible, and when you see it, you even get the feeling that the door is literally floating in the air. Such models of doors and sliding systems are perfect for more modern interiors, as they look very unusual and elegant.

    Aristo, or rotary

    It is characterized by the fact that it works from rotary mechanism. As a rule, it is used to create aluminum profiles and other accessories from the same material. This is one of the most reliable and durable sliding systems, which at the same time saves space. It is quite easy to install and operate.

    Advantages and disadvantages

    A huge advantage of any sliding design is its compactness. It allows you to reduce doorway and makes it lighter. It is also able to make the passage wider and higher, especially suspended models. Sliding design does not require a swing, so you can furnish the room into which the door leads at your discretion, without taking into account the design of the door.

    It is also a great advantage that this the door moves very smoothly and silently. She will not wake up the household with unnecessary claps and other loud sounds. Besides, sliding mechanism The door prevents animal tails or children's fingers from slamming as the door closes very smoothly.

    Separately, it should be noted the advantages of coplanar sliding door systems. This mechanism minimizes the appearance of unnecessary gaps, which cannot be said about other doors. This ensures not only the proper level of sound insulation, but also the whole structure, when closed, creates a feeling of unity. Another advantage of the coplanar system, as well as other types of closed structures, is that the guide skids are closed from prying eyes. In addition, since they are inside the structure, dust and dirt do not accumulate on them, so it becomes quite easy to care for the structure.

    The coplanar system has a lot of advantages over compartment doors, since the passage is completely free and the door takes up much less space. The same can be said about the models - "accordions", since they are compactly assembled near the door jamb when opened.

    The sliding door mechanism has various latches, which is its undoubted advantage. This way you can fix the door in a fully open, half-open or closed position and you can adjust and make it easier for yourself to pass. In addition, such a mechanism and this function allows you to prevent the doors from slamming at the wrong time.

    Another advantage of sliding doors is that they do not require a small amount of space and can be installed by almost anyone. This applies most simple mechanisms, such as a coupe or an accordion. In addition, a big advantage is appearance such products. They look more interesting compared to classic swing doors. There are more options for design and choice different types mechanism.

    But such doors have a number of disadvantages. So, some systems, such as coplanar, have limitations in the size of the doorway.

    They are only acceptable if the width of the door leaf is between 150 and 300 cm. If the width doorway more or less, then installation will be impossible. These systems also assume the presence of restrictions on weight. The door must weigh no more than 55 kg, otherwise the mechanism may not withstand. The same applies to hanging sliding doors.

    The disadvantage of almost all sliding doors and their mechanisms is that they cannot provide the proper level of sound insulation. This is due to the fact that the sliding system is not completely hermetic, in which it is very inferior swing structures. This shortcoming is due to the fact that the design includes many components and there are gaps between them. That is why sliding doors are very rarely used for installation in the kitchen or bathroom. They easily let in smells, extra noise and can distract other household members.

    Noisy meeting rooms it is better not to install such doors, since sounds will penetrate anyway. Due to the low tightness, the sliding door mechanism does not allow for proper thermal insulation, since cold air flows can penetrate from one room to another, forming drafts.

    Another disadvantage is the high cost of such structures compared to classic swing. By itself, this mechanism is not very reliable and requires special care. It must be lubricated and checked periodically.

    Swing doors are more resistant to external influences than sliding doors. Sliding models do not cope with the protective function. In addition, some mechanisms can jam, especially hidden types that hide inside the wall.

    Thus, to correct this shortcoming, you may even have to dismantle the wall, which is difficult and problematic.

    How to choose?

    Hinged synchronous mechanisms are more suitable for light door panels. This is due complex design and in the first case, the presence of an upper guide, and in the second, the presence of several parallel guides. Plastic structures are also perfect for them. For doors - "accordions" often use fabric elements.

    The most versatile is the chipboard door. Such material is lightweight and practical, in addition, it is quite inexpensive. On a par with them are universal models made of MDF, which also fit any door mechanism. Such models are often pasted over with veneer or decorated with carvings by milling.

    For many sliding door mechanisms, an important requirement for the canvases is the presence of absolutely identical sashes. That is, they must be equal in length and width.

    This applies to both coplanar models and accordions, synchronous models and sliding doors. Hidden-type telescopic structures are completely unsuitable for the use of glass doors.

    For pencil cases, you can even pick up heavy models made of wood. For folding mirror doors you can use the compartment mechanism. For lightweight door structures, almost any type of mechanism can be used. In this case, you can choose a telescopic, hidden, synchronous mechanism, as well as rotary or radius products. For models with two doors, a coupe-type mechanism is most suitable.

    When choosing a mechanism for sliding doors, great attention must be paid to the materials from which it is made. It is better if it is metal, even if the door frame is wooden. When choosing, try not to save on the purchase of such doors. Otherwise, the design will serve you for a very short time.

    Much attention is paid to the roller system. This is especially true at the time of installation, since a skew or incomplete set constituent parts and guides can lead to breakage of the entire structure. When choosing, also rely on the acceptable materials for a particular mechanism, as well as on the weight of the structure itself. If the mechanism is not too reliable, then it is better to give preference to light materials for the door. When choosing a mechanism, try to also take into account the size of the doorway and the canvas itself.
