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

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

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

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

It is initially required to properly dismantle old door... This applies primarily to the box and platbands. Dismantling is carried out using: an ax, a hammer and an assembly.

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

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

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

The next stage of the installation is the measurement. First, you need to think about which structure will be installed: sliding or swing. After all, each of them has a number of opening features.

Sliding doors fit well and fit into small rooms. Indeed, due to them, space is significantly saved. To install them, you will need to purchase a special design, necessary work swing doors.

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

The swing door opening method 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 the future doors has been selected, you can proceed to measuring the existing opening. To later determine whether it requires changes (decrease or increase). It is worth remembering here that the width of the box should be 110 mm less than the opening.

For this type of door, the opening should already be wider than both canvases 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 compliance of the timber, and if discrepancies are detected, adjust it to the required dimensions. Further, 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 just before that. Accordingly, if the diameter of the self-tapping screw is 3.5 mm, then the drill should be 2.5 mm.

Box installation

Because, how accurately the installation of the box is carried out, in fact, most of the performance and the subsequent correct operation of the double door itself depend. This requires the use of a level with three eyes and wooden wedges.

Priority of actions:

1. The assembled box must be placed in the opening. Using a level, you need to align the structure. Here you will need to monitor not only the coincidence of the vertical lines, but also then, whatever the edges of the box do not go beyond the opening itself.
2. After setting the box in all parameters, 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. Placing plugs and fixing the box in the opening.
6. Foaming the remaining gaps.

Only after all this, the door is hung, locks insert and framing.

Here everything goes much faster and easier:

1. The rollers are screwed to the door leaves.
2. Height markings for roller guides.
3. Outlining, using a level, line. Fixing a bar on it (its thickness should be from 40 to 50 mm). It is screwed to the wall.
4. Installation of guides on the bar.
5. Hanging the door.

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

Everything you need to know about door bolts (end latches). We tell you with what internal doors they are used and we explain what to look at when choosing. At the end of the article, there is an instruction for inserting a deadbolt into a double door leaf.

1. WHAT DO WE NEED A SLIDING DOOR BARS FOR?

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

Usually, one flap is left movable, and the other is fixed. What for? Firstly, one sash is almost always sufficient for the passage. Secondly, if you leave both 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 latches. Such fittings are invisible on the door and reliably immobilizes the sash (which other double door latches cannot boast of - ball and magnetic mechanisms). There is nothing to say about usability - everyone knows how the latch works. Do you need to open both doors to carry furniture or ventilate the room? Click at the top, click at the bottom, and you're done.

Mortise crossbars are also used for other purposes - for example, to fix a window sash or a wardrobe door. Someone also locks the rear side of the pickup with them. There are a lot of options for use, you just need to choose the right product in size.

2. HOW MANY BATTLES DO I NEED FOR ONE DOUBLE DOOR?

Usually two are installed: one at the top and one at the bottom of the end (or rather, the vertical strapping bar) of the canvas. To do this, at the installation sites, two grooves are milled for the dimensions of the crossbar. Mating parts 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. However, the fixation will be less stable. In addition, this option is only suitable for light canvas (~ up to 30 kg).

3.HOW TO CHOOSE A MUTTING PIN FOR DOUBLE WOODEN DOOR?

Drawing diagram of Palladium crossbars: pay attention to the dimensions

[Insertion depth]

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

[Body width]

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

[Body length]

For the lower ledger, 140 mm is sufficient. 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, we recommend a 140 or 160-165 mm ledger for top fastening. This is a versatile option.

It makes no sense to pick up on standard door long end latches. They will be visible from the end when the door is open. In addition, this saves space on the strapping beam and retains the ability to install a multi-point lock-rail (a device popular in Europe that requires a lot of space at the end).

4.HOW TO INSTALL THE DOOR CRANK (END LOCKET) FOR DOUBLE DOORS

Installation of the crossbar into the canvas is carried out before inserting the hinges. You will need tools: a router, a chisel, a hammer, a screwdriver, a pencil, a ruler or a carpenter's square. Installation order:

1.Attach the end ledger from the edge of the blade (from the top edge for the top ledger, from the bottom edge for the bottom ledger). Make sure it is exactly in the center of the end, and trace with a pencil.

2.Place a 16 mm router bit under the waling depth.

4.If the door deadbolt is square, hack off the edges with a chisel.

5. Install the deadbolt in the groove.

6.Using a screwdriver, tighten the screws from the kit.

It is better to install the strike plate of the end latch when the doors are already hung, but the handles are not yet 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 fits freely, but without noticeable backlash (otherwise the door will click). After that, screw the striker plate onto the remaining screws from the kit, without sinking it in the box. Done!

Are you looking for where to buy end bolts for swing double doors? In our catalog you will find two models in seven colors, lengths 140 or 165 mm (optimal for interior and exterior doors).

All crossbars "Palladium" are made of steel with TSAM (many competitors have steel with silumin, which is worse than TSAM in everything). Although we position them as door latches, you can use them however you like.

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 spaces with wide doorways.

Compared to a solid sheet, a similar design in open form takes much less space... This product is also popular for its looks. 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 the installation of interior doors.

• construction foam;
• puncher, chainsaw or grinder;
• bars;
• self-tapping screws;
• milling cutter;
• crossbars;
• racks;
• spacers made of wood;
• metallic profile;
• electric drill;
• building level;
• corner brackets;
• plumb line;
• 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, this can be done by using a hammer and several screwdrivers different sizes... After that, the opening should be cleaned of excess plaster mix and construction foam. To expand the doorway, you must use a grinder or a punch. In this case, everything will depend on the wall material. You can reduce the opening to the desired size using a plaster mixture.

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

Drawing of a double 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 web, 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 added to it a few millimeters for mortgages. As an example, we will consider a standard door width of 60 cm and a box thickness of 2.5 cm: (600 + 3 + 25) * 2 + 4 \u003d 1260 (mm). The height of the opening can be calculated in the same way. However, in this case, you need 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 \u003d 2050 (mm). In the process of manufacturing the threshold, you will need to sum up the height of the door, the two thicknesses of the box and the gap between it and the canvas, which is multiplied by 2.

How to assemble a door frame correctly?

Installation and assembly of the finished box

Some of the door options are sold complete with fasteners and frame elements, which are ready for assembly. In this case, the installation process will not take much time. You will need to decide on the side of the opening 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 into the holes, which are located in the cuts on the side parts of the box racks. After that, all the elements are pulled together to the maximum and fixed with angle brackets. For this, recesses are located on the back of the box.

Door blocks can be supplied prepared for installation, with the structure provided with grooves for hinges. However, in some cases, there are no such slots. Then you need to perform some steps to cut them.

How is the box installation carried out?

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

Door frame manufacturing scheme.

Its dimensions are two widths of the canvas and 6 mm for possible slots. 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 posts that are adjacent to 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 post upward, the third is placed between them, but screwed in at the top.

After that, the hinges are installed. On the door, it is necessary to note the location of the fastening and turning mechanism. To do this, measure 20 cm on the end of the canvas and attach a loop. You will need to circle its outline simple pencil or a sharpened knife. At this point, to the desired depth, you need to select a groove. It can be prepared with a chisel, but in order for the groove to be made accurately, you will need to use a router. With this tool, you can get the job done quickly and without errors.

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

Sectional door frame installation.

Next, you need to put the doors on the box, mark the place for the hinges on the bars, and then make a recess 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 used quite rarely, since experienced craftsmen such devices raise some doubts.

It is necessary to install hinges on all doors and posts of the structure. Then the crossbar is installed on any of the canvases.

How is the box installed 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 secure the side struts. Between them and the wall, spacers made of wood must be mounted.

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). 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. Do-it-yourself door leaf will need to be hung in the appropriate place, after which a hole needs to be drilled for the locking plate of the bolt at a small angle.

How to mount a double-leaf interior door?

Installation of guide elements

Installation of a sliding door.

Sliding doors are a good replacement for 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-leaf doors, you will need to pay attention to the material from which they are made. If a single guide element is sufficient for a wooden structure, then a heavy glass structure will require the installation of several fixtures. The bottom guide must be planned so that the structure can be deepened into the floor. It must be fixed before finishing the floor base. The horizontalness 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 must 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 the fittings for them. The choice of loops is unlikely to be difficult. It is enough to take a model that is reliable and resistant to damage. The difficulty is the selection of handles. Today they are represented by an impressive variety of options, so it can be difficult to decide.

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

What are the door handles?

The pens are represented by an impressive assortment. At the same time, there are simple staples 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 clips, 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 sockets.
2. Clips on the bar.
3. Knobs.

Of course, simple staples are not taken into account. They are often installed in rooms where there is no need for decor or design selection. Moreover, each type of handle is suitable for a specific canvas. The most difficult choice is for sliding structures that need interior 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 the handle "Moon". Their creation belongs to a British manufacturer. Such latches have a separate locking mechanism, which is simply necessary in separate rooms.

Overhead models and their design features

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

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

The principle of installing such latches 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 specially designed for this type of boxes. The fastening principle is based on 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 of any material, represented by carved elements, can be in the form of plants, animals.

Stranding models and bar structures: their main features

Interesting varieties of door handles are twists. 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 leaves. They often prefer models decorated in metal colors. Also in demand are bronze designs with ornaments, 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 - to unlock and lock doors. The latches with locks are based on a tongue latch and a special push handle. Such designs are also produced specifically for double swing doors. Moreover, they are additionally equipped with locking mechanisms or a traditional stopper. The advantage of the models is the ability to fix the canvases in the closed position.

Rosette handles and interesting knobs: design advantages

Recently, designs on the outlet are 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 makes it easier to open.

The handle is based on 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 varied, so you can safely use them in your own interior, installing on boxes.

Attention! Choose handles designed for double swing doors. If you decide to purchase just two handles on an outlet, 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 the models on the rosette. They have a complex structure, and the design is represented by a swivel-type handle in the shape of a ball. The opening and closing mechanism is hidden inside it. It is also worth understanding that this mechanism is capricious in operation. For double swing models, it becomes not the best solution. Therefore, it is better to choose more simple modelsthat will harmoniously complement your interior.

Choosing the material of the door handle

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, for glass doors, metal or glass handles are suitable. Plastic models will look awkward. For wooden doors it is worth choosing wooden or metal handles. Plastic structures are complemented 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, it is worth considering the style of the room. For modern trends, for example, minimalism, wood or bone options 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 parameter for choosing a material for door handle become its characteristics. If strength and safety are important to you, opt for metal products. To add grace and lightness to the room, choose glass structures for canvases. Models made of plastic will help to save money, but prepare for the fact that they are unlikely to last long.

Choosing a handle lock

Many people 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. Fale.
2. Roller.
3. Magnetic.

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

Folding 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.

A popular type is considered a magnetic mechanism. Its main advantages are noiselessness and softness of work. For this, there are two magnets on the door frames. They are located opposite each other. The result of installing 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 the durability of operation. There are also models of handles without an opening mechanism at all, for example, a staple.

When choosing pens, listen to your own requirements and preferences. You should be comfortable using them in your interior. Perhaps such a parameter of choice as tactile sensations will come to the fore. Metal models will be cold, carved structures will be uncomfortable. 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 home master able to complete work in a day. Next, we will analyze step by step how to properly install interior door two ways.

Options 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 frame for them are actually made.

Material selection

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

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

You should not rush to install such a door, it is certainly light and cheap, and it may look pretty decent, but not everything is in order with reliability, such a structure can even be broken with a fist, plus it is highly likely that in a couple of years it will begin to delaminate.

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 canvases at home is an excellent solution if there is no money 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 installing wooden doors is the most the best option, but this is wrong, here you need to look at the quality and the manufacturer's firm. Believe me, sometimes it is better to insert interior doors from good MDF laminaterather than 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 evaluated.

If you decide to change the 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 issues

The size of the doorway for installation is perhaps the most important of the initial parameters. To this day, all such designs 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 in their own way.

So if our minimum width of the canvas starts from 600 mm and further with a step of 100 mm, it reaches 900 mm, then France produces canvases starting from 690 mm, but the graduation also goes with a step of 100 mm.

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

Interior doors have clear standards that need to be checked before installing the interior door yourself.

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

Along the perimeter of the box in block buildings, you can leave any gap, up to a few millimeters, the main thing is that the box becomes even, but if we cut doors in a wooden house with our own hands, then we set the tolerance at least 15 mm, it is needed in case the house gives shrinkage.

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

1. Only a door leaf is sold - this option is good if the door is planned to be installed on an old frame;
2. The canvas is on sale along with the box, but the box is disassembled, here, even before installing 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 blocks with a ready-made box, curtain, 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 the interior doors in the opening, the complete installation of the interior door provides for the arrangement of platbands, accessories (if necessary) and fittings, so it is also advisable to take them right away, otherwise the shade may not be suitable later.

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

There is one more important question - when to install interior doors during renovation? 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 the floor plinths.

Two mounting options

We figured out the size tolerances and other pressing issues, now it's time to find out how to install the interior door yourself. But in order to assemble and install a structure, we need a tool.

A few words about the tool 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 the openings between the box and the wall, wedges are required;
• A hammer;
• Chisel;
• Screwdriver;
• Electric drill;
• Plumb line;
• Level;
• Pencil;
• Roulette.

Install the interior door yourself without good tool unreal.

Important! Safety regulations categorically prohibit cutting wood with a grinder. If your health is dear to you, don't even think about it.

Of the auxiliary materials for installing doors you will need:

• Polyurethane foam;
• Masking tape;
• Self-tapping screws different sizes and sections;
• Anchor bolts with dowels.

Opening preparation

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

But in real conditions, the preparation of the doorway for the installation of the interior door ends with adjusting the dimensions to the box, because then the impartial cracks will be foamed and covered with platbands, so there is no point in bringing special beauty.

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

There is one important point here: often the installation of a double interior door requires the expansion of the opening, and so, when it comes to the walls, they can be "redrawn" as you see fit. But if the wall is 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.

Assembling the box

Do-it-yourself door frame can be assembled in two ways - this is by cutting the corners of the upper bar at 45º and joining the slats at right angles. Both are fine, but a 45º corner dock is said to look more elegant.

Really high-quality corner trimming can be done only 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 spoil the boxes.

The vertical posts are cut at 45º first, after which you can proceed to trimming the upper horizontal plank. 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 top bar with a template.

• You put the upper bar cut on one side and move it along the cut of the template;
• Then go to the opposite side of the door and use the same template to mark the cut line.

Trimming the top plank at an angle using a bevel.

Now we lay out the finished, trimmed box strips 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 as they should be;
• The strips of the box when screwing in 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 (our self-tapping screw is 3.5 mm);

Preparation for bonding the box.

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

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

Fixing the box with an angle cut.

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

We start by trying on the upper cross member, we will cut it between the two side posts. Some craftsmen mount the crossbar above the side posts, there is not much difference, here it is already as convenient for anyone.

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

Now we just need to insert the upper bar between the two side posts, drill holes for a pair of self-tapping screws and fix 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 upper bar, then drill and drive the screws from above, as shown in the diagram below.

Installing hinges and handles

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

Hinges are overhead and hidden. It is easier to work with overhead butterfly hinges, since you do not need to cut anything in the door leaf and frame, so we will start with them.

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

Installation of loops begins with marking on the canvas itself. According to the rules, the distance from the upper or lower 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 the tape measure is not at hand, then use the loops themselves, there standard size is equal to 100 mm.

We make markings for the installation of loops.

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

All hinges have pockets for the screw heads, so make sure that these sweats "look" up. If the hinges are installed the other way around, then the heads of the screws will remain above the hinges, respectively, the doors will not close to the end.

We drill holes for butterfly hinges.

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 patterns from fiberboard (3 mm thick) between the box and the canvas.

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

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

Self-installation of secret loops is not much more difficult than the above method. The difference is that grooves for the hinges must be cut in the door leaf and the frame. This is done with a mallet, chisel and knife.

Cut out grooves for mounting hidden hinges

As for the installation of the door handle, you can read about this in detail, as well as watch the video in this article. And do not forget that the hinges must be greased, you can learn about the rules for greasing.

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

Method number 1. Classic

At the moment, our box racks must be cut to the height of the opening, the hinges and the lock are embedded, the door is closed, and templates with a thickness of 3 mm 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.

Fixation is quite a crucial moment, here we set 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 a plumb line.

In order for the door block not to fall out from a strong push, it must be rigidly fixed with anchor bolts or at least with 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 points of drilling;
• Put the box in place and fix it with anchors. The box should be clearly 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 hidden somehow. You can close them with a decorative strip or plastic overlays.

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

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

Plus, at the time of blowing out the foam, the door block must be assembled and three millimeter templates must be inserted around the perimeter, this will protect the box from deformation.

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

Method number 2. Metal hangers

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

Using 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 the 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, there is a greater likelihood of extrusion of the pillars and crossbar with foam, therefore, installation on hangers is optimal here.

Output

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

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