How to install double interior doors. High-quality installation of double-leaf interior doors. Benefits of double swing interior doors

Installation of interior double doors has a number of features. First of all, this concerns the availability of special tools, and secondly, technological features.

First you need to get acquainted with their division into types. It occurs according to the following parameters:

• By general principle: can be hinged and sliding;
• production material: aluminum, glass, plastic, MDF or wood;
• by design: paneled, paneled glazed, deaf, massive.

Initially, you need to properly dismantle old door. This applies primarily to the box and platbands. Dismantling is carried out using: an ax, a hammer and a pry bar.

It is important to remember that if the old box needs to be kept intact, then the procedure should be as follows:

• removal of platbands;
• cleaning from cement and foam;
• removal of self-tapping screws, in the case when the beam was fixed with nails, they can also be carefully cut off with a grinder.

After removing the box, the remnants of leveling materials are removed from the doorway using a perforator. When the plaster is laid with high quality, has a smooth surface, it can be left only by cleaning off the remnants of the mounting foam.

The next step in the installation is to take measurements. First you need to consider what kind of structure will be installed: sliding or swinging. After all, each of them has a number of opening features.

Sliding doors are well suited and fit into rooms with a small area. After all, due to them, space is significantly saved. To install them, you will need to purchase a special design, necessary work hinged doors.

Note: you can build a plasterboard box, where the doors will subsequently “go in” after opening. However, it will significantly reduce the space of the room that could be used for furniture.

The swing method of opening door panels is very popular. After all, it increases the level of sound insulation, unlike a sliding door. However, swing doors take up more space in the room and require more free space for maneuvers. This type of door is most often installed in large rooms.

After the design of future doors is selected, you can proceed to measuring the existing opening. To subsequently decide whether it requires changes (reduction or increase). It is worth remembering here that the width of the box should be 110 mm less than the opening.

Under this type of door, the opening should already be wider than both leafs and another plus 100mm.

Assembly and installation of the door frame

Before proceeding with the collection of the box itself, it is required to verify the conformity of the beam, and if discrepancies are identified, adjust it to the required dimensions. Next, the procedure is as follows:

It is worth remembering: so that in the process of screwing in the screws, the wooden elements remain intact, without cracks, you should drill a hole immediately before this. Accordingly, if the diameter of the self-tapping screw is -3.5 mm, then the drill should have - 2.5 mm.

Box installation

Because of how accurately the installation of the box was carried out, most of the performance and the subsequent correct operation of the double-leaf door itself actually depend. This will require the use of a level with three eyes and wooden wedges.

Sequence of actions:

1. The assembled box must be placed in the opening. Use a level to level the structure. Here you will need to monitor not only the coincidence of the vertical lines, but also then, no matter what the edges of the box go beyond the opening itself.
2. After setting the box in all respects, it must be fixed. This is where wooden wedges come in handy.
3. Drilling holes for self-tapping screws in the box. In parallel, it is necessary to make marks on the wall.
4. Drilling holes in the wall according to the marks. To do this, you need to pull the box out of the opening.
5. Putting traffic jams and fixing the box in the opening.
6. Foaming of the remaining cracks.

Only after all this, the door is hung, the locks are inserted and the frame is framed.

Here everything goes much faster and easier:

1. The rollers are screwed to the door leafs.
2. Marking the height of the guides for the rollers.
3. Outlining, with the help of a level, lines. Fixing a bar on it (its thickness should be from 40 to 50 mm). He is screwed to the wall.
4. Installation of guides on the bar.
5. Door hanging.

Now you see that there is nothing difficult in installing any type of interior double doors.

Everything you need to know about door bolts (end bolts). We tell you with what interior doors we use them and explain what to look for when choosing. At the end of the article, instructions for inserting a crossbar into a double door sash.

1. WHAT DO YOU NEED mortise door bolts?

Swing double doors are popular in private houses, apartments and commercial premises. They are double (equal) and one and a half (unequal).

Usually, one leaf is left movable, and the other is fixed. For what? Firstly, one leaf is almost always enough for the passage. Secondly, if both are left working, then they can no longer be closed with a latch. In addition, the doors will be unstable in the opening, annoying with their knock from the slightest draft.

The passive sash is fixed with crossbars - they are also called end stops or end bolts. Such fittings are invisible on the door and reliably immobilize the sash (which other double door latches cannot boast of - ball and magnetic mechanisms). There is nothing to say about ease of use - everyone knows how the latch works. Need to open both doors to bring in furniture or ventilate the room? Click on the top, click on the bottom, and you're done.

Mortise crossbars are also used for other purposes - for example, for fixing a window sash or wardrobe door. Someone locks the tailgate of the pickup truck with them. Application options - weight, you just need to choose the right product in size.

2. HOW MANY DOUBLE DOOR SHOULD BE NEEDED FOR ONE DOUBLE DOOR?

Usually two are installed: one at the top and one at the bottom of the end (or rather, a vertical strapping bar) of the canvas. To do this, two grooves are milled at the installation sites for the dimensions of the crossbar. The mates are attached coaxially to them: one to the upper bar of the box, the other to the threshold (or to the floor).

If there is no threshold, and you are not ready to make a hole in the floor, install one upper end bolt. True, the fixation will turn out to be less stable. In addition, this option is only suitable for light canvas (~ up to 30 kg).

3. HOW TO CHOOSE THE LATCH FOR A DOUBLE WOODEN DOOR?

Drawing diagram of Palladium crossbars: pay attention to the dimensions

[Infeed Depth]

In modern interior doors, the strapping beam is rarely thicker than 25 mm. If you have just such doors, then in order not to weaken their design, select crossbars with a tie-in depth of up to 15 mm (like Palladium).

[body width]

On sale you can find reinforced built-in latches up to 3 cm wide. But this is an option for thick and very heavy entrance canvases. In turn, wooden interior doors usually have a thickness of up to 50 mm. And if you narrow the selection to the middle segment and economy - up to 40 mm. In both cases, we recommend buying a 16 mm wide end bolt. Our Palladium 5-1/2" and 6-1/2" models are just the right fit.

[body length]

For the lower crossbar, 140 mm is enough. As for the top, the longer it is, the lower it will be located and the more convenient it is to open it. Therefore, choose its length so that you and everyone else who will use the door do not have to reach for it. If you have standard doors 2 m high, then we recommend a bolt 140 or 160-165 mm for the top fastening. This is a universal option.

It's pointless to choose standard door long end caps. They will be visible from the end when the door is open. In addition, this saves space on the strapping bar and retains the ability to install a multi-point lock-rail (a popular device in Europe that requires a lot of space at the end).

4.HOW TO INSTALL A DOOR BAR (END LATCH) FOR DOUBLE DOORS

The installation of the crossbar in the canvas is carried out before inserting the loops. You will need tools: a milling cutter, a chisel, a hammer, a screwdriver, a pencil, a ruler or a carpenter's square. Installation order:

1. Attach the end bolt from the edge of the leaf (from the top edge - for the top bolt, from the bottom edge - for the bottom bolt). Make sure that it is located strictly in the center of the butt, and circle with a pencil.

2. Place a 16 mm cutter under the depth of the ledger.

4. If the door bolt is square, chop the edges with a chisel.

5.Install the bolt into the groove.

6. Screw the self-tapping screws from the kit with a screwdriver.

It is better to install the striker of the end latch when the doors are already hung, but the handles have not yet been cut in. The main thing at this stage is to accurately mark the hole on the box where the pin will slide. The future hole must be strictly coaxial with the pin.

After marking, drill a hole. The diameter should be such that the pin enters freely, but without noticeable play (otherwise the door will click). After that, screw the striker onto the remaining self-tapping screws from the kit without sinking it into the box. Ready!

Looking for where to buy end bolts for swing double doors? In our catalog you will find two models in seven colors with a length of 140 or 165 mm (optimal for interior and entrance doors).

All Palladium crossbars are made of steel with TsAM (for many competitors, they are made of steel with silumin, which is worse than TsAM in everything). Although we are positioning them as door latches, you can use them in any way you like.

No tags

A double-leaf model of an interior door is most often used in the following cases:

• the door opening is large;
• the room is small.

Double doors are often used in small rooms and rooms with wide doorways.

Compared to a solid web, this design in open form takes much less space. This product is also popular due to its appearance. The door leaf can be hinged or sliding. Sometimes you can find swinging models, but they are not popular. Installation of such a design is not particularly difficult.

Tools and materials that will be needed to install the door:

Tools for mounting interior doors.

• construction foam;
• perforator, chainsaw or grinder;
• bars;
• self-tapping screws;
• milling cutter;
• crossbars;
• racks;
• spacers made of wood;
• metallic profile;
• electric drill;
• building level;
• angle brackets;
• plumb;
• knife;
• cellophane;
• masking tape.

How to prepare an opening for installing double-leaf doors with your own hands?

Before installing such a structure, you will need to prepare an opening for it. If you need to dismantle the box earlier installed door, then this can be done by using a hammer and several screwdrivers various sizes. After that, the opening should be cleaned of excess plaster mixture and construction foam. To expand the doorway, you must use a grinder or puncher. In this case, everything will depend on the material of the wall. You can reduce the opening to the desired size using a plaster mixture.

The walls must be prepared for the final finish and aligned to the maximum - the door frame should not adjust to the bumps and go out of plane.

Drawing of a double-leaf swing door.

After that, the door opening is calculated. On sale you can find interior double doors that do not fit the dimensions of a standard opening. The calculation of its width can be made according to the following scheme: the width of the canvas, the gap between it and the bar, as well as the thickness of the box are summed up. The result obtained must be multiplied by 2 and add a few millimeters to it for mortgages. As an example, we will consider standard width doors 60 cm and box thickness 2.5 cm: (600 + 3 + 25) * 2 + 4 = 1260 (mm). In the same way, you can calculate the height of the opening. However, in this case, it will be necessary to take into account the gap between the structure to be installed and the floor base, which is approximately 1-2 cm: 2000 + 10 + 25 + 15 = 2050 (mm). In the process of making the threshold, you will need to sum up the height of the door, two thicknesses of the box and the gap between it and the canvas, which is multiplied by 2.

How to properly assemble a door frame?

Installation and assembly of the finished box

Some of the door options are sold complete with fasteners and box elements, which are prepared for assembly. In this case, the installation process will not take much time. You will need to decide on the opening side of the structure, measure the length of the racks, taking into account the unevenness of the floor base. In accordance with its height, it is necessary to saw off the lower part of the racks. Next, dowels are installed in the holes, which are located in sections on the side parts of the racks of the box. After that, all the elements are pulled together to the maximum and fixed with angle brackets. To do this, recesses are located on the back of the box.

Door blocks can be supplied ready for installation, the design provides grooves for fitting hinges. However, in some cases there are no such grooves. Then you need to perform some steps to cut them.

How is the box installed?

In the process of assembling the box, the first thing you need to do is to fit the bar to the dimensions of the canvas.

Scheme of manufacturing a door frame.

Its dimensions are two web widths and 6 mm for possible gaps. When calculating the height of the box, 10 mm for the clearance in the lower part and 3 mm for the clearance in the upper part must be added to the dimensions of the entire structure. The top bar and the ends of the uprights that adjoin it must be cut at an angle of 45 °.

Next, you need to assemble the door frame. Its corners are connected by several self-tapping screws, the length of which should reach the central part of the second bar. Two fasteners are screwed at an angle from the side rack element upwards, the third is placed between them, but is screwed at the top.

After that, the hinges are installed. On the door it is necessary to note the placement of the fastening-swivel mechanism. To do this, on the end of the canvas you need to measure 20 cm and attach a loop. Its outline will need to be circled with a simple pencil or a sharpened knife. At this point, at the desired depth, you need to select a groove. It can be prepared with a chisel, but in order for the recess to be made accurately, you will need to use a milling cutter. With this tool, you can do the job quickly and without errors.

Through the plate of the loop, which is laid in the recesses, with an awl, it is necessary to mark places for fasteners, and then drill holes for them. Their diameter should be 1.2-1.4 mm less than the diameter of the fasteners. Using the same method, on any of the wings you need to make a recess for the crossbar.

Sectional door frame installation.

Next, you need to put doors on the box, mark a place for the hinges on the bars, and then make a notch on them in the same way as on the canvases. On sale you can find fastening mechanisms that do not need preparatory work. However, they are rarely used because experienced craftsmen such devices raise some doubts.

Hinges must be installed on all sashes and racks of the structure. Then a crossbar is installed on any of the canvases.

How is the installation of the box in the opening?

In the process of installing the box in the opening, using the building level, you will need to check the accuracy of its placement.

The structure is fixed to the wall with self-tapping screws of great length (approximately 8-10 cm). The first step is to fix the side racks. Spacers made of wood must be mounted between them and the wall.

The resulting space around the box must be filled with construction foam. It is necessary to take into account the level of its expansion (1:5). The elements of the door block will need to be protected from building foam. After it has hardened with a knife, you need to carefully remove the excess, and then close the gap with a platband. You will need to hang the door leaf with your own hands in the appropriate place, after which you need to drill a hole for the locking plate of the crossbar at a small angle.

Installation of guide elements

Sliding door installation.

Sliding doors are a good alternative to swing doors. With their help, you can free up some of the space, which is important if repairs are being carried out in a small apartment.

When choosing double doors, you will need to pay attention to the material from which they are made. If a single guide element is enough for a wooden structure, then a heavy glass structure will need to install several fixtures. The lower guide element must be planned so that the structure can be deepened into the floor. It must be fixed before finishing the floor base. The horizontality of this element must be checked with a building level.

To determine the position of the upper guide element, which is fixed first of all, the door must be leaned against the opening and a horizontal line should be drawn along its upper part. In this case, it will be necessary to take into account that a gap of 12-14 mm should remain between the floor base and the canvas. It will be possible to immediately place a gasket of the required thickness under the structure.

After the interior doors are purchased, it remains to pick up accessories for them. The choice of loops is unlikely to cause difficulties. It is enough to take reliable and damage-resistant models. The difficulty is the selection of pens. Today they are represented by an impressive variety of options, so it can be difficult to decide.

Important! Handles on the door - products that allow you to achieve comfortable operation of the canvas. With their help, it becomes easy to close and open the door. Sometimes they are supplemented with a latch or lock. In addition, they act as an interesting element of decor that complements the interior. Therefore, their choice is important, even small details should not be missed.

What are door handles?

Handles are represented by an impressive assortment. At the same time, simple staples are found in stores, as well as elegant carved options. The choice should be based not only on the appearance or their resistance to damage, but also on the installation features. This is important if you decide to attach latches, handles or locks to the box yourself. There will be no particular difficulties if you choose easy-to-install varieties.

Among the variety of door handles, there are three main categories:

1. Products for outlets.
2. Plank fasteners.
3. Knobs.

Of course, simple brackets are not taken into account. They are often installed in rooms where there is no need for decoration or design selection. Moreover, each type of handle is suitable for a particular canvas. The most difficult choice is for sliding structures that need internal or hidden models.

For swing double doors, the choice of products is more impressive. You can give preference to those that look elegant. An interesting option becomes handles "moon". Their creation belongs to the British manufacturer. Such latches have a separate locking mechanism, which is simply necessary in separate rooms.

Overhead models and features of their design

If you decide to choose overhead products for your own doors with two leaves, you should familiarize yourself with their internal device. After brackets, these models are considered the simplest in design. They are designed to increase the convenience of opening and closing doors. Clamps are used independently or together with mortise and overhead locks.

Such designs work on the principle of pressing, so they are often called pressure. These models, when pressed, hide the tongue in themselves and the door opens. When you release the handle, the tongue snaps into place. It acts as a latch that holds the canvas in the closed position.

The principle of installing such clamps with locks on the box is extremely simple. Do not worry that they will not complement the double doors. It is enough to indicate this feature in the store and you will be offered those models that are specifically designed for this type of box. The principle of fastening is based on the location in the right place, and screws are used as fasteners.

Remember that products designed for double swing doors are called paired. However, their installation has no fundamental differences. An important advantage is the ability to choose decorated products for the interior box. They are made from any material, are represented by carved elements, can be in the form of plants, animals.

Twisting patterns and plank constructions: their main features

Interesting varieties of door handles - twist. They are two elements at once, connected by a single metal axis. Their hallmark becomes a spherical shape and a symmetrical arrangement on the door leafs. Often prefer models decorated in metal colors. Bronze designs with ornaments are also in demand, adding a touch of luxury to any room.

Models on the bar are considered the most popular. They are used for interior doors, allowing you to perform several functions at once - unlock and lock doors. At the heart of the latches with locks is a reed latch and a special push handle. Such designs are also produced specifically for double swing doors. At the same time, they are additionally equipped with locking mechanisms or a traditional stopper. The advantage of the models is the ability to fix the canvas in the closed position.

Handles on a socket and interesting knobs: the advantages of designs

Recently, designs on the outlet are beginning to be in great demand. They resemble balls or discs. The principle of operation is based on the action of a lever. To open the model, it is rotated around its axis. Sometimes the handles are also egg-shaped, which simplifies the way of opening.

At the base of the handle is a round figured plate. With its help, the product is fixed in the closed position of the double door. Appearance products are elegant, and the choice is diverse, so you can safely use them in your own interior by installing them on boxes.

Attention! Choose handles designed for double swing doors. If you decide to purchase just two handles on a socket, their installation will be difficult or even impossible. If difficulties arise, contact the consultants who work in each store, including online portals.

Knob handles for the door frame become an alternative to models on the outlet. They have a complex device, and the design is represented by a rotary type handle, which has the shape of a ball. Inside it is a mechanism for opening and closing. It is also worth understanding that this mechanism is capricious in operation. For double swing models, it becomes not the best solution. So it's better to choose more simple models, which will harmoniously complement your interior.

Choosing door handle material

When choosing handles for double interior doors, consider the material from which they are made. Ideally, it should match the material of the canvas or be in harmony with it. Among the most popular options are the following:

1. Tree.
2. Metal.
3. Plastic.
4. Strained glass.
5. Natural raw materials. They can be bones, horns.
6. Combined options.

Make the right choice. For example, metal or glass handles are suitable for glass doors. Models made of plastic will look awkward. For wooden doors you should choose wooden or metal handles. Plastic structures are supplemented with products from a similar material. For metal doors it is better to choose metal handles to achieve harmony. If you do not know what to give preference to, take a closer look at the combined materials that will complement any interior boxes.

Additionally, the style of the room should also be taken into account. For modern trends, for example, minimalism, options made of wood or bones will not be the best option. But these same handles will optimally complement classic interior or a room decorated in the now popular eco-style.

The last material selection parameter for door handle become its characteristics. If strength and safety are important to you, make a choice in favor of metal products. To add grace and lightness to the room, choose glass structures for canvases. Plastic models will help save money, but prepare for the fact that they are unlikely to last for a long time.

Choosing a handle lock

Many decide to install a lock for double doors. It helps to restrict movement and entry into the premises. Today, the following types of locking mechanisms are distinguished:

1. Fallen.
2. Roller.
3. Magnetic.

Each of them is considered to be in demand. Roller - one of the most famous. It can be found more often than others in doorknobs. This is a roller or ball on a spring. When it hits the groove, the door is fixed in the closed position. At this point, it will be impossible to open it.

Falevye mechanisms are useful for movable doors. In order for them to close, you will have to get the oblique tongue into the groove. In this case, you do not need to use a key - the mechanism functions perfectly without it.

The magnetic mechanism is considered to be in demand. Its main advantages - noiselessness and softness of work. To do this, there are two magnets on the door jambs. They are located opposite each other. The result of the installation of such a mechanism will be smoothness and lightness. If you are looking for comfort, you can safely choose just such a mechanism, it will not disappoint and will guarantee a long service life. There are also models of handles without an opening mechanism at all, for example, staples.

When choosing handles, listen to your own requirements and preferences. You should be comfortable using them in the interior. Perhaps such a choice parameter as tactile sensations will come to the fore. Metal models will be cold, carved designs are uncomfortable. The wood will be pleasant to the touch, but it may lose its original appearance over time. Pay attention to all the details, and then the door handle will harmoniously complement the door, and its use will be as comfortable as possible.

Until recently, installing interior doors with your own hands was a rather difficult task and required serious experience and skills from a person. Now everything has become much easier, having a good tool and knowing the procedure for installing interior doors, any House master able to finish the job in a day. Next, we will step by step analyze how to install it correctly. interior door two ways.

Variants of canvases for interior doors.

Before you put an interior door, you must first select it. When choosing, there are 2 main criteria - this is the size of the structure and the material from which the doors and the box to them are actually made.

Material selection

Not so important is the installation of an interior door in wooden house or in a room of an urban high-rise building, the design must be not only beautiful, but also reliable, and this primarily depends on the material.

Fiberboard is perhaps the most common option. The design is a hollow box on both sides closed with thin sheets of fiberboard and based on a frame made of wooden bars.

You should not rush to install such a door, of course it is light and cheap, and it can look quite decent, but not everything is in order with reliability, such a design can be broken even with a fist, plus there is a high probability that in a couple of years it will begin to exfoliate.

MDF is the golden mean between cheap fiberboard and good wooden structure. The array is dense, durable, and most importantly completely environmentally friendly. Self-assembly interior laminated MDF sheets at home is a great way out if there are no funds for installers, and beautiful door I want to.

The MDF canvas must be laminated with high quality, then it will not visually differ from the wooden one.

Natural wood - traditionally it is believed that the installation of wooden doors is the most the best option, but this is wrong, here you need to look at the quality and the manufacturer. Believe me, sometimes it is better to insert interior doors from good MDF laminate than to take a raw pine, which in six months will lead.

At the time of buying wooden canvases the quality of the forest must be carefully assessed.

If you decide to change interior doors and you have a high-quality wooden loot, then it is not necessary to touch it, you can only replace the canvas. In this case, the technology for installing interior doors will be much easier.

GOSTs, tolerances and unclear questions

The size of the doorway for installation is perhaps the most important of the initial parameters. To this day, all such structures are made according to Soviet GOSTs, by the way, the Chinese are also guided by these dimensions, but in Europe, despite the supposedly uniform standard, many countries do it their own way.

So if our minimum web width starts from 600 mm and further in increments of 100 mm, it reaches 900 mm, then France produces canvases starting from 690 mm, but the graduation also comes in increments of 100 mm.

Germany, Spain and Italy, as well as all the countries of the former socialist camp, in this respect are guided by almost the same standards as our manufacturers.

Interior doors have clear standards that you need to check before you install an interior door yourself.

As for tolerances, a gap of 3 mm is left between the box and the canvas itself on the sides and top. According to the rules, at least 20 mm must be made between the floor and the canvas. This slot is needed for normal ventilation in the apartment.

Any gap can be left along the perimeter of the box in block structures, up to several millimeters, the main thing is that the box becomes even, but if we cut the doors in a wooden house with our own hands, then we set a tolerance of at least 15 mm, it is needed in case the house gives shrinkage.

When an interior door is selected, installation is already the last stage, before that you need to read the description in detail, because the price can be indicated depending on the configuration, there are 3 options:

1. Only the door leaf is for sale - this option is good if the door is planned to be installed on an old box;
2. The canvas is sold together with the box, but the box comes unassembled, here, even before you install the interior door with your own hands, you will have to cut it to size and assemble the box, which in most cases is even good;
3. Fully assembled units with a finished frame, canvas, locks and hinges are installed only if preparation of the opening is not required. There it is enough to cut the racks in height and install the interior door yourself.

Do not forget that it is not enough just to install interior doors in the opening, a complete installation of an interior door provides for the arrangement of platbands, extensions (if necessary) and accessories, so it is also advisable to take them right away, otherwise the shade may not come up later.

Installation of interior doors will not be complete without platbands and fittings.

There is one more important question- when to install interior doors during repairs? So, the instructions for installing interior doors say that such structures are mounted at the very end of the repair, after finishing the walls, floor and ceiling, but before installing floor skirting boards.

Two mounting options

With dimensional tolerances and other acute issues sorted out, now it's time to find out how to install the interior door yourself. But in order to assemble and install the structure, we need a tool.

A few words about the instrument and related material

To install interior doors, we need:

• A hacksaw for wood, but ideally it is better to have a miter saw, it does not leave chips, plus you can set the exact cutting angle there;
• To expose openings between the box and the wall, wedges are required;
• Hammer;
• Chisel;
• Screwdriver;
• Electric drill;
• Plumb;
• Level;
• Pencil;
• Roulette.

Install interior doors yourself good tool unreal.

Important! Safety regulations categorically prohibit cutting a tree with a grinder. If you value your health, don't even think about it.

Of the auxiliary materials for installing doors you will need:

• Mounting foam;
• masking tape;
• self-tapping screws different sizes and sections;
• Anchor bolts with dowels.

Opening preparation

Ideally, before installing an interior door, the edges of the walls should, if not plastered, then at least leveled with a cement-sand mortar.

But in real conditions, the preparation of the doorway for the installation of an interior door ends with fitting the dimensions to the box, because then the impartial cracks will foam up and close with platbands, so there is no point in bringing special beauty.

It is advisable to level the doorway before installing the box.

There is one here important point: often the installation of a double interior door requires an expansion of the opening, and so, when it comes to piers, they can be “redrawn” as you see fit. But if the wall is load-bearing, then a slight expansion of no more than 5-7 cm is allowed, otherwise there may be problems, both with the wall and with the law.

Box assembly

Do-it-yourself door box can be assembled in two ways - this is with cutting the corners of the upper bar at 45º and joining the bars at a right angle. Both methods are good, but it is believed that the 45º corner joint will look more elegant.

Really high-quality corner trimming can only be done with the help of trimming, if you are assured that an ordinary plastic miter box and a hacksaw for wood are suitable for this, do not believe it, you can ruin the boxes.

The vertical posts are cut off at 45º first, after which you can proceed to trimming the upper horizontal bar. In order to set aside 3 mm, it is convenient to use a piece of fiberboard as a template.

We measure the gap relative to the upper bar with a template.

• You put the top bar cut on one side and slide it along the cut of the template;
• Then go to the opposite side of the door and, applying the same template, mark the cut line.

Trimming the top bar at an angle using trimming.

Now we lay out the finished, trimmed slats of the box on the floor and once again control the dimensions.

It looks like a door frame cut at an angle.

• The box is fastened in stages. First you need to tightly connect the planks to each other the way they should be;
• The slats of the box when screwing the screws can crack, so that this does not happen, before assembling, we need to drill channels for the screws. This is done with a 2.5 mm drill (we have a 3.5 mm self-tapping screw);

Preparing to fasten the box.

• Now you can screw the screws into the ends of the box on both sides, and there should be 2 screws on each side of the corner.

There is a small nuance here, the vertical bar of the box to which the hinges will be attached completely on both sides does not need to be tightened, we still have to remove it.

Fixing the box with cutting at an angle.

If miter saw is not in your arsenal, then it is better to mount the box strips at a right angle. Perhaps this is not so aesthetically pleasing, but the step-by-step instructions will be somewhat simpler.

We start by trying on the upper crossbar, we will cut it between the two side posts. Some masters mount the crossbar above the side racks, there is not much difference, here it’s already convenient for anyone.

Along the perimeter of the box, we have a side in which the door leaf lies when closing. To embed the upper cross member, on the side racks we need to remove this side. To do this, we apply the upper crossbar to the rack, mark and cut the side with a hacksaw, and clean out the place for installation.

Now we just have to insert the top bar between the two side posts, drill holes for a pair of self-tapping screws and secure the inserted bar with self-tapping screws.

If you decide to put the bar on top of the racks, then there you will need to cut the inner side on the top bar, then drill and drive the screws from above, as shown in the diagram below.

Do-it-yourself installation of a bar placed on top.

Installing hinges and handles

For a door, installing hinges is one of the most important steps. In principle, you can embed a lock and hang hinges after mounting the box in the opening, but if you mount the doors yourself (without assistants), then it is better to do it right away.

Loops are overhead and hidden. Butterfly overlay hinges are easier to work with, since you don’t need to cut anything in the door leaf and frame, so we’ll start with them.

A little advice: if the door should open on the right side, then you insert the hinges on the right, respectively, for left-hand opening, the hinges must be mounted on the left rack.

Installation of loops begins with markings on the canvas itself. According to the rules, the distance from the top or bottom point of the canvas to the loop should be 200 - 250 mm. You can measure with a tape measure, as in the photo below, but if there was no tape measure at hand, then use the loops themselves, where the standard size is 100 mm.

We make markings for the installation of loops.

Do not confuse: the small (inner) part of the butterfly loop is attached to the door leaf, and the large one, to the box post. Before screwing the screws under them, you need to drill holes, only after that the screws are driven.

All hinges have recesses for the heads of the screws, so make sure that these recesses “look” up. If the hinges are installed the other way around, then the heads of the self-tapping screws will remain above the hinges, respectively, the doors will not close completely.

We drill holes for butterfly loops.

The box is practically assembled, now we put it on the floor and put the door leaf inside. As you remember, we should have 3 mm around the perimeter of the canvas, so we immediately insert as many homemade fiberboard templates as possible (3 mm thick) between the box and the canvas.

One part of the loop is screwed to the canvas, in order to screw the second part of the loop to the box, we make a mark on the box. Then we unscrew the self-tapping screws fixing the bearing vertical bar and fasten the counterpart of the hinges to it. Then we return the bar of the box to its place and fix it completely.

We fasten the hinges to the vertical rack of the box.

Self-installation of hidden loops is not much more complicated than the above method. The difference lies in the fact that in the door leaf and the box you need to cut grooves for the hinges. This is done with a mallet, chisel and knife.

We cut grooves for mounting hidden loops

As for the installation of the door handle, you can read about it in detail, as well as view it on the video in this article. And do not forget that the hinges must be lubricated, you can find out about the rules for lubrication.

There are different ways to install interior doors in a wall opening, it all depends on the specific conditions. Next, we will consider the simplest and most popular options.

Method number 1. Classic

At the moment, our box racks must be cut to the height of the opening, the hinges and lock are embedded, the door is closed, and 3 mm thick templates are inserted between the canvas and the box.

When door block inserted into the opening, first of all, wooden or plastic wedges are driven around the perimeter, they will hold the block until it is finally fixed.

The classic scheme for installing interior doors using wedges.

Fixing is a rather crucial moment, here we expose the block vertically and horizontally. Keep in mind: the wall is not always strictly vertical, so check the box with a plumb line.

It is better to check the vertical by plumb.

In order for the door block not to fall out from a strong push, it must be firmly fixed with anchor bolts or at least long self-tapping screws. We recommend using anchor bolts with a thickness of 6 - 8 mm.

The principle is simple:

• Drill a through hole in the box and slightly drill into the wall;
• Remove the door block and drill holes for dowels at the drilling points;
• Put the box in place and fix it with anchors. The box should become clear in level, since before that we have already verified everything.

If you fix the box with long self-tapping screws, then they are installed around the entire perimeter with an interval of half a meter, but the caps of the self-tapping screws need to be somehow hidden. You can close them with a decorative strip or plastic lining.

Anchor bolts are a powerful thing and 3 points are enough to fix the box - two points under the hinges and one under the lock plate. In combination with mounting foam It's enough.

Now we fill the perimeter of the box with mounting foam. We move from the bottom up, the foam must be blown out without fanaticism, because when it expands, it can squeeze out the door frame.

Plus, at the time the foam is blown in, the door block must be assembled and three-millimeter templates must be inserted around the perimeter, this will protect the box from deformation.

Remember: only on the "bare" foam (without screws or anchors) the door block cannot be fixed.

Method number 2. Metal hangers

If mounting the box on self-tapping screws or anchors is not suitable for you, the same can be done using metal hangers. These hangers are used for mounting frames under drywall.

Use of hangers to fix the door frame.

The technology is similar:

1. Collect the box;
2. Insert the box into the opening and level it;
3. Fix the box with wedges in the opening;

1. Bend the wings of the hangers along the wall;
2. Mark the entry points for dowel-nails and drill holes for them;
3. Attach the wings of the suspensions to the walls with dowel-nails;
4. Fill with foam and wait until it hardens.

The size of the box for double-leaf interior doors is twice as large, respectively, the probability of squeezing out the racks and the crossbar with mounting foam is higher, so installation on suspensions is optimal here.

Conclusion

Both of the above methods have been tested in practice and work perfectly. The same craftsmen who wish to install interior sliding doors we have prepared step by step instructions.

Installing interior doors with your own hands is not as difficult as it seems.
