In an effort to make your home more comfortable and cozy, you often come up with the idea of replacing conventional swing doors with sliding doors (they are also called sliding, sliding, hanging). The good news is that you can install sliding doors yourself without any problems. The bad thing is that a normal mechanism costs about the same as a high-quality blade. What is captivating about them is that when open they hardly “eat up” space. They either hide in the wall (a better, but more difficult to implement option), or move along it.
You can hang interior sliding doors yourself
All this is true, but there is a significant drawback - a very low degree of sound insulation, especially in the sliding door version. When the canvas simply covers the opening. When installed in a pencil case (in the wall), the situation is a little better, but the degree of sound insulation of a swing door cannot be achieved even with this installation method. If all this doesn’t scare you, you can start studying the systems, selecting them, and then installing them.
Features of sliding doors
In fact, sliding doors are not a feature of the door, but a method of opening. Almost any interior door can be installed in this way by additionally mounting a mechanism - a profile and rollers, which will be closed with a decorative panel. However, there are small exceptions. This way you cannot install models:
- with protruding decorative elements - moldings, since the gap between the door and the wall should be minimal - only 2-3 mm (for this reason, special requirements are placed on the evenness of the wall);
- with a rebate - these models are created specifically for better sealing of the doorway. Closely adjacent to the door frame, doors with a rebate provide sound insulation and the absence of drafts.
Which one to choose?
Sliding doors are used in residential premises where there are no temperature changes, significant mechanical stress and other unwanted loads. Therefore, it makes no sense to choose canvases from the point of view of strength and reliability.
As a rule, they are selected based on their decorative qualities - taking into account the characteristics of the interior, wall decoration, and furniture design.
For some users, the main selection criterion is the external qualities of the canvas. This is a completely acceptable and somewhat justified approach, since the aesthetic value of the sliding panel is no less important than the functionality.
It is inappropriate to advise anything in an area where it is customary to be guided by taste and personal preferences. We can only advise you to choose canvases based on the working qualities of the material and possible troubles associated with them.
For example, it is not advisable for dog owners to install canvases made of soft materials - pets will quickly scratch them when trying to open them. In addition, you need to carefully examine the fittings - rollers and guides. Their strength affects the quality of work and the overall service life of the blade.
Sliding doors: installation
It is recommended to choose the door size so that the door leaf is 5-8 cm wider than the doorway. This is a prerequisite if the sliding door is installed without refining the doorway, i.e. without extras and platbands. But if you install the door in a different way - by refining the doorway, a slight discrepancy in size can be leveled out by installing platbands.
The third installation option is used when you need to embed a lock. To form a seat, which is not provided for during standard installation, an additional strip is used from which the protrusion is made.
Advantages and disadvantages
The advantages of sliding doors are considered to be:
- attractive appearance;
- economical use of apartment space;
- safe and convenient use;
- the ability to quickly zone or vacate areas of the premises;
- adjustment, correction of asymmetrical or uneven openings;
- a large number of design, size, and construction options;
- prices for sliding panels are no different from the cost of other types of interior doors;
- Self-installation is possible, even with no experience.
There are also disadvantages:
- when the canvas moves, noise is heard, which is transmitted through building structures and is clearly audible to neighbors below;
- sliding doors protect rooms well from prying eyes, but do not provide protection from noise, odors, and do not have sufficient strength;
- sliding panels are not able to retain thermal energy in the room;
- the canvas does not need free volume, but requires a free wall plane - if there is a narrow section of the wall, it makes no sense to install a sliding structure.
- a large load on the mechanics forces frequent repairs and replacements, which requires expense and effort.
Despite some disadvantages, sliding doors are very popular. They are in demand due to their safety and ease of use, ease of installation and the ability to independently install the canvas and move it from one opening to another.
The only really important drawback is the need to have space to move the canvas. The sash needs a free section of the wall equal to its width. If there is furniture, household appliances nearby, or there is another opening, installation of the sliding panel becomes impossible.
The problem can be partially solved by rearranging the furniture. But it is impossible to remove interfering openings or protruding sections of walls, which automatically cancels the installation of sliding doors.
If the opening is wide
If the doorway is much wider than standard sizes, double sliding doors are installed. These are the same double interior doors, but they open by moving the leaves along the rails. It is very convenient if the package includes a synchronizer. This is an additional mechanism that, when one leaf is pulled back, simultaneously moves the other leaf to the opposite side.
The sliding door can be fixed in a certain position or use the automatic opening/closing function. Note! The sliding mechanism must be monitored so that the door does not jam at the wrong time. Choosing a high-quality opening mechanism will help prevent this risk. Fortunately, all doors from our catalog are equipped with reliable devices.
Types of sliding structures for premises
Sliding doors consisting of one leaf are fairly simple designs; there is not a wide variety of models, however, there are several aspects that allow the classification of products. There are many more types of multi-leaf systems, for example, telescopic or radius.
Mechanism installation method
Depending on the location chosen for installation of the structure, all sliding models can be divided into two types.
Sliding doors located inside the opening. The entire system is completely located in the plane of the load-bearing wall, and the opening sash is recessed into it. This principle of operation allows us to eliminate one of the disadvantages of sliding models, namely the difficulty of placing interior items directly next to the wall along which the canvas moves. In this case there is no interference for this. In addition, on the wall itself you can easily hang accessories and other elements: clocks, bookshelves, photographs, paintings, etc. There is also nothing that interferes with the installation of decorative floor skirting boards.
Sliding doors placed inside the opening
However, for such a sliding door to function, a niche in the wall must be thought out in advance, even at the stage of renovation work in the home. Otherwise, you will have to install a special frame, which will reduce the usable area of the room.
A structure mounted on the wall above the doorway . The door moves along its surface. In apartments and houses, sliding systems are usually installed, equipped only with an upper guide. This allows you to get rid of an unsightly and inconvenient threshold. The lower supporting guide is added only when the reliability and durability of the structure requires it (for example, if the canvas is very heavy).
Door mounted on the wall above the doorway
The mechanism can be mounted both on the wall and on the ceiling. In the latter case, it becomes possible to visually increase the height of the room.
Important! High demands are placed on the quality of the fittings used to install a sliding door. You should not save on these products, since they largely determine the functional characteristics of the entire system.

The appearance of the videos themselves is of great importance. It is desirable that the wheel has a pressed bearing. This will help extend the life of the system. The shock-absorbing spring will add softness to the ride.
Material
The design of doorways is of great importance for creating a harmonious and holistic interior. The choice of type of structure is made based on the preferences of the owners of the premises and their material capabilities, as well as compliance with the overall design. The door leaf can be made from:
- wood;
- materials containing wood fibers;
- glass;
- plastics;
- metal (aluminium).
Glass cloth
Using glass in the manufacture of a sliding door allows you to add light to the room and visually expand the space. Glass and mirror panels can be installed anywhere, since they are completely unaffected by external influences, both climatic and mechanical. Therefore, installing such models in bathrooms or kitchens does not create problems.
Glass sliding door
The only significant drawback that glass construction has is its relative fragility. However, modern methods of glass processing make it possible to create an impact-resistant material that is not so easy to break. The disadvantages include the need for frequent and careful maintenance of door panels made of glass. Otherwise, the door will look sloppy. Well, the price category of many models does not belong to the budget category.
To make the glass sliding structure look attractive, many techniques are used:
- glass coloring in bulk;
- material tinting;
- glass frosting;
- sandblasting;
- painting, etc.

Mirror doors can significantly increase the area of a room.
Wooden doors, panels made of wood materials
The classic version of an expensive interior door is structures made of solid wood. However, they are quite bulky, which often leads to the need to use a bottom guide.
Wooden interior door
Modern analogues of wooden doors that imitate natural materials are products made from MDF panels or laminated chipboards. The first option seems to be the most preferable in terms of product performance characteristics, as it is more resistant to various environmental influences. But products made from chipboard are economical, which often becomes a decisive factor when choosing a model.
Models finished with natural veneer are as close as possible in terms of aesthetic characteristics to wooden structures.
Plastic door
The retractable model can also be made of polymers. These designs cannot boast of particular attractiveness and variety of finishes, however, modern technologies make it possible to give such products various, quite interesting textures.
Plastic door
The advantages of polymer systems include their lightness, durability, resistance to moisture and relative low cost.
Features of adjusting plastic doors
Metal door
The door can be made of aluminum. This option for designing an opening is quite rare, as it is suitable for a limited number of styles. Connoisseurs of comfort are unlikely to like the abundance of metal in the room. But when decorating a room in a high-tech or modern style, aluminum door structures will perfectly suit the decor.
It is also popular to combine different materials when making canvases. The most commonly used combination of various materials with glass. When choosing a sash option for decorating a doorway, a combination of wood and glass, as well as metal and glass elements, is popular.

What size opening should be for a sliding door?
The size of the opening for a sliding door depends on whether you will decorate the doorway with trim and trim from the same door, or whether the doorway will be left without a frame
Doorway without frame
The height of the doorway without refining should be no higher than the height of the door leaf. The width of the doorway should be at least 50 mm narrower than the width of the door leaf. For example: if we take a door leaf of standard sizes 800*2000, then the size of the opening should be 750*2000
Doorway with frame
Ennobling or framing the doorway allows us to set the desired width and height of the opening at the time of installation. As mentioned above, the height of the opening should ultimately be the same as the height of the canvas, and the width should be at least 5 cm narrower. Taking into account the width of the platbands, we have a power reserve of 5 on each side. Thus, the maximum dimensions of a doorway for a refinished sliding door can be a couple of centimeters wider than the door leaf and 5 cm higher than the door leaf. For example: if we take a door leaf of standard sizes 800*2000, then the size of the opening should be no more than 800*2050 mm.
Features and installation procedure
You can install sliding doors yourself even without much experience. It is quite possible to do without installers. It will take a little time, and also installation instructions. We will try to give a detailed description of the process with photos and video materials.
Self-installation of sliding interior sliding doors
The systems may differ slightly, but the general rules remain the same. There are several requirements that must be met before installation:
- The opening must be level, otherwise you will have to take a canvas that covers all deviations with a margin.
- The load-bearing capacity of the sides of the doorway should be high, as should the wall above it.
- The opening must already be finished: plastered and painted, covered with wallpaper or decorated with decorative panels.
Next we proceed to assembly. First you can attach the rollers. Different manufacturers have their own recommendations. Some recommend retreating 1/6 of the width of the door leaf from the edge; in other systems, they are attached immediately from the edge, and the mounting plates provide the indentation. This is the system we install: in it, roller platforms are installed immediately from the corner.
Marking the installation location of the rollers
We center them, measuring so that the distances are the same. Having positioned the plate, use a pencil or marker to mark the locations for the fasteners. Drill holes in the marked places. The diameter of the drill is 1 mm less than the diameter of the screw.
Securing the Roller Shoes
We set the plates and screw in the screws. The length of the fastener depends on the weight of the canvas, but not less than 70 mm. We twist them exactly perpendicularly, otherwise unnecessary stress will arise.
Installation of rollers
Supports for the rollers are inserted into the installed plates. They are fixed with a lid on the side surface. Next, roller platforms are screwed onto the threaded pins.
Roller platforms are screwed onto the pins
It is also convenient to install handles and locks before hanging. They need special, mortise ones. If you bought a ready-made kit, the required holes are available. If you have used a regular canvas, you will have to trace the outline with a pencil and remove the excess with a chisel. After the handle or lock fits into the recess, the attachment points are marked, holes are drilled for them and the fittings are installed.
Handle installation
Next, you can begin installing the guide. With mounted rollers, this will be easier: you know exactly at what height the bottom edge of the rail should be.
The most convenient way is to hang sliding doors on a dry wooden beam. Its cross-section is less than 50*70 mm, its length is twice the width of the door leaf + 5 cm. We cut the guide to the same length.
We measure the length of the carrier and mounting bar
Having aligned the guide along the beam, it is attached to the beam with self-tapping screws no less than 8 cm long. The number of fasteners is at least three, departing 10 cm from the edges and in the middle (more often is possible, less often - not).
Attaching the guide to the beam
Now you can measure at what height to mount the timber. A guide with a beam is “rolled” onto doors with installed rollers. This way you can accurately note how tall the doors are. We drill at least four holes in the side edge of the beam for mounting to the wall.
The guide with the beam “rolls” onto the rollers on the door
Add 7-10 mm to the resulting mark - the doors should hang and not shuffle along the floor. 7 mm is the minimum gap, which is sufficient if there is no floor covering in the opening. If they are planned (later to lay laminate, carpet, linoleum, etc.), then the thickness of these coverings must also be taken into account.
Trying it on to the doorway
To prevent the canvas from “walking” during installation, it is wedged with small wooden wedges. At least two stops are required - near both rollers.
We wedge the canvas
Having placed the beam against the wall and adjusted its position using a level, we mark its position with a pencil. If the wall allows, you can fasten it to the wall through and through, but for this you need to use self-tapping screws at least 120 mm long, or better yet, place it on anchor bolts.
If the wall, for example, is concrete, the installation of dowels is required. To do this, you need to transfer the marks for the fasteners to the wall. This can be done using a thin and long drill, the diameter of which is smaller than the drilled hole.
Transfer the marks to the wall using a thin drill
An even simpler option: a long thin nail. It is inserted into the hole and a mark is made on the wall with a couple of blows. The following procedure is known: drill holes for the dowel plugs, insert the plugs, hammering them in if necessary. Then we install the doors.
Attaching sliding doors to the wall
Stoppers must be secured along the edges of the guide. They are inserted from the sides, the required location is established experimentally (so that the canvas covers the opening completely when closed, and rolls back sufficiently when opening. They are fixed using clamping screws.
Installing stoppers on sliding doors
Having opened the doors, we install the flag roller on the floor. It fits into a groove cut into the bottom of the blade. It is necessary to ensure that the doors do not deviate vertically.
Installing Flag Roller
First, we insert it into the groove, mark holes for fasteners, drill, then secure with short self-tapping screws (length about 15-20 mm).
This is what the installed flag roller looks like with the doors open
At this point we can assume that the sliding doors have been installed. They are already fully functional. Finishing work remains. The mounting beam with the guide is covered with a decorative overlay, matched to the tone of the door leaf. It can be nailed directly to the timber with finishing nails.
The decorative overlay can be nailed directly to the beam
Only when you put it out, make sure that the wheels are closed. It’s much more beautiful this way)) Now that’s it, you’ve installed the sliding doors with your own hands.
A video tutorial on how to install such a door is shown below. There are several installation options.
We install cassette-type sliding doors (in a pencil case)
The process of installing the guide and hanging the door leaf is almost identical to those described above. There is no need only for finishing, but all other stages are necessary. Instead of installing a decorative strip, a false wall is mounted at a distance of at least 10 cm from the wall. It is usually made from plasterboard profiles, which are covered with wall plasterboard. But this is not important - you can use gypsum fiber board or plywood, or any other suitable material.
Where does the distance of 10 cm come from? The thickness of the door leaf and the gaps on both sides are 5 cm. At least another 5 cm is added to this for installation of the profile. So it turns out to be 10 cm.
Since the main load will fall on the wall, the frame made of profiles need not be reinforced. If such a wall does not seem very reliable to you, you can insert wooden blocks inside, which are screwed with self-tapping screws. This will make the structure very rigid.
The basic principles for calculating a pencil case for a sliding door, as well as marking features and principles for preparing a doorway for installation, see the video.
Main advantages
This design visually expands the space and saves useful space. It is easy to use; the doors open easily, without any effort. The design is resistant to mechanical damage.
Hinged doors do not open on their own, for example due to strong wind or draft. Installing an automatic opening system makes it even easier to use the door and extends its service life; installation can be easily done independently.
Should I try to install the doors myself?
Replacing a door in an apartment or house occurs for various reasons: breakage or unusable condition, interior renovation or complete repairs. And they usually trust the installation of a new door to the craftsmen, but you can do it yourself.
Hanging interior door
In principle, there is nothing complicated in installing an interior door. The main thing is not to rush and be smart, then everything will work out.
Hanging structure with an interesting design
Carefully plan your work process, find out what material the model is made of and what technological features this product has. In addition, installation requires compliance with a certain sequence in the work process.
How to decide on a color?
Interior doors play an important role in the interior of a room and must be of high quality and attractive.
Hanging door in the interior
The main requirement: the canvas should not stand out against the background of the walls and the entire interior. Therefore, it is advisable to select colors that echo the color of furniture, wallpaper and flooring. If you don’t yet know how the room will be decorated, then you should stick to neutral shades. This will be the best solution.
If you are a fan of non-standard things, then choose a door in a rich and bright color. Then, in order to maintain harmony, it is advisable to update the color of the baseboards or window trims. It looks attractive.
If the guide is furniture, then for an ideal combination you will need a door 3-4 shades lighter. To dilute the too dark color of the model, use colored inserts.
Hinged door in the interior
An original solution would be a door with sides of different colors. Such models are ideal if neighboring rooms differ greatly in design and style. Such models are ordered individually.
Principles of sliding systems
Based on the design features, there are two large classes of sliding systems:
- sliding-folding;
- parallel-sliding.
The sliding-folding design resembles a book or an accordion: when opened, the sash does not move along the vertical surface, but moves to the side. There are single-leaf and double-leaf models. One canvas is formed by 2 or more vertical sections, which are connected to each other by a hinged fastening.
The design of the sliding and folding door resembles a book
Disadvantage of the device: it does not prevent the penetration of odors and sounds. Therefore, sliding doors are used primarily as a decorative element and for conditionally dividing living space into zones.
The parallel-sliding design is represented by one or several sashes. They move on rollers on rails along or inside the wall. This device provides a high degree of sound insulation and has a long service life . It is ideal for wardrobes and interior doors.
Parallel sliding door leaves move along or inside the wall
Parallel sliding systems have several varieties, which differ from each other in the number of sashes and in the method of opening.
Sliding doors
They may consist of one or two leaves. They work according to the same scheme: they move along a vertical surface. The only difference is that double-leaf doors have leaves that diverge in different directions. It is worth noting that this model saves space and decorates your interior. It is ideal for the living room, children's room, kitchen, dressing room.
Sliding doors save living space
Cassette doors
This model differs from the previous one by the presence of a niche in the wall, where the panels slide in when the door is opened. You can buy a niche ready-made complete with a sliding system or make it yourself from plasterboard or other building materials.
The cassette door leaves slide into a niche in the wall
Radius doors
The radius model is a non-standard design solution. It differs from other models in that it is not designed to save space, but rather the opposite. Therefore, this type of door is intended for large premises: supermarkets, offices, country houses, and sometimes apartments.
The radius door has a semicircular shape
As for the design features, the radius model is similar to traditional sliding solutions. The main difference is the semicircular shape of the products.
Cascade doors
This version of the sliding system is designed in the same way as the traditional one. But it is not similar to other designs in that each blade moves on a separate rail .
In a cascade system, each leaf moves on its own rail
This system is used as a partition between rooms or all the doors are assembled on either side of the wall and the room is closed only to the width of one of them.
Internal doors
They are designed so that the entire structure is located inside the opening. The canvases move towards each other, leaving ½ of the opening for passage.
This configuration allows you to change the location of the part of the opening open for passage
Saving Tips
Installation of sliding doors should be carried out on high-quality roller carriages. Despite the high cost of the mechanisms, they significantly save money in the future. Cheap rollers quickly break down with frequent use and need to be replaced. High-quality carriages will last a long time.
The cheapest way to make a door leaf is from plain or laminated chipboard or MDF. This material can be decorated to your taste. This can be done using varnish, paint, self-adhesive film, wallpaper or any other method.
For wooden doors, you should choose material that has been dried in special cabinets. Otherwise, the structure may become deformed in the first months of operation, and then the frame will have to be redone.
Questions and answers
Finally, we should consider a few questions that most users often have. You can answer them in advance, without waiting for them to become relevant:
Are there locks or latches for sliding doors?
Yes, such castles exist. They are equipped with a special type of tongue with a step that engages with the socket. There are a lot of options for the design and design of such mechanisms on sale; you can choose the appropriate and most convenient lock or latch.
Is it possible to install sliding doors on an opening in a load-bearing wall?
If during installation it is not necessary to cut out part of the wall (as required by the installation of cassette-type panels), then sliding walls can be installed on load-bearing walls. Cassette structures can only be installed on internal partitions that do not perform load-bearing functions.
How dangerous are glass sliding doors?
They are not dangerous. Tempered glass has high strength and hardness. It is possible to break it, but to do this you need to set yourself a task and purposefully act in this direction. Glass sheets pose the only danger to the owner’s wallet - they are expensive and require qualified paid installation.
What maintenance is required for sliding doors?
It is necessary to monitor the condition of the rollers and regularly clean the grooves in the lower guides, where dust and small debris constantly accumulate. You also need to lubricate the rollers and monitor the strength of their attachment to the canvas, and tighten loose screws. In addition, it is necessary to maintain the cleanliness of the canvases themselves (which is usually done during each cleaning. Otherwise, there are no special requirements.
How to reduce the noise level when moving the sashes along the guides?
This is a difficult question, since it all depends on the material and weight of the canvas, the thickness and material of the ceiling and many other factors. In any case, it is recommended to place an elastic band (rubber or EPDM) under the guides. This will make the sash move softer and quieter.
Differences in sliding mechanisms
The mechanisms that form the basis for the functioning of sliding systems are of two types:
- Hidden or in-wall. The name already speaks for itself: the device provides for the movement of the canvas inside the wall. This design must be planned at the stage of wall construction, since a door holder will be installed inside it. It expands by reducing the usable area, but this frees up space along the vertical surface. You can put furniture here and hang pictures.
- Open or external. This system does not require special construction work, so it can be installed at any time. The sliding structure is designed so that the doors move on rails along a vertical surface. Therefore, space on one or both sides of the wall should be left free.
If we compare these two types with each other, then the open mechanism gives more freedom of action . You can choose a four-panel design, which is especially suitable for wide openings.
With two guides
The canvases move on wheels along guides that are located below on the floor or above. Due to this device, the doors do not warp during operation.
The disadvantage of the design is the regular contamination of the bottom rail groove.
Door leaves with two guides do not warp
With one guide
This type of mechanism assumes that the main parts of the structure will move only on the top rail. This option is called “suspended”, since the canvas is in a suspended state.
Installation of a system with one guide is carried out only on strong walls. The device includes: aluminum profile, frame installation kit, roller mechanisms, stoppers.
The quality of the design largely depends on the rollers. Avoid plastic wheels without bearings, as they negatively affect the service life and overall performance of the device . Choose rollers with silicone or rubber tires. Their quantity is determined at the rate of: 1 set per 70 kg of door leaf weight.
To prevent the doors from falling off the upper rails, stoppers are used during installation. And special flags prevent the appearance of gaps. The main advantages of this mechanism are: soft and quiet movement of the valves and a highly durable system.
Stoppers prevent the sashes from derailing
The choice of type of guide mechanism depends on the type of product. So, when installing a cascade door, two roller mechanisms and guides with 2 gutters are installed on each leaf, and upper and lower rails are equipped for the glass door.
Manufacturing materials
There are no restrictions on these design characteristics.
- Tree. A traditional material that is well known to everyone, its cost falls into the middle price category. Can be used for a long period of time and is repairable.
This door is sure to attract the attention of your guests.
Photos of interior doors made of wood in the interior - GlassO. Only impact-resistant types or triplex are used. The latter is very expensive, but has the highest physical parameters. The service life is practically unlimited.
Glass sliding interior doors
Sliding glass doors. Sandblasting - OSB, MDF, chipboard, fiberboard. The simplest and cheapest designs; to improve the appearance, a polyethylene film imitating various types of natural wood is glued to the surface. Performance characteristics meet the requirements for budget products.

Wide interior doors
You can often find combined options; wooden door leaves have glass inserts and vice versa. The specific choice should take into account the actual design style of the interior, the purpose of the doors and the planned intensity of use.
Rollers are made of metal or wear-resistant plastic; each material has its own strengths and weaknesses.

Doors on rollers
Interior doors on rollers have gained great popularity due to the ability to use them to save space and beautifully decorate the interior, due to various stylish design elements. Simply put, they are a variant of the design used in the manufacture of sliding wardrobe doors.
Hinged doors on rollers are quite heavy, so they open and close smoothly. Interior doors with a compartment system are rarely used in everyday life due to the strict mechanical requirements for precision movement, so the design uses a bottom rail, which worsens performance in residential premises.
Also, dirt constantly collects at the place where the rails pass, which in turn interferes with the normal movement of the door leaf, leads to deterioration in the quality of the supporting element and even to the roller itself jumping out. A top-mounted roller door has no such disadvantages.
To ensure that hinged interior roller doors have the least amount of play, auxiliary roller blocks are used in the lower part of the structure. There may also be special pads for limiting travel, which are installed on the floor.
All roller doors are divided into various subtypes, differing in the installation method and opening principle.
