The size of the frame of the opening under the compartment door. What should be the opening for installing an interior door

The doors in the house are extremely important, especially the way they are located. The opening is no less important. It is necessary to be able to correctly calculate its dimensions.

Building features

By itself, the opening implies the presence of empty space in the wall.

Doorways have their own construction features.

• As a rule, openings already have parameters in accordance with certain standards, and doors are also selected according to them.
• The openings were used when the old door was installed. This means that almost every one of them is the result of eliminating the previous door frame. But there are situations when it needs to be finalized to certain parameters.
• Openings can be cut into solid walls. Their creation in a wall made of wood or concrete is not difficult. It is recommended to pre-calculate whether the strength of the building will suffer.

From the above, the conclusion follows: it is necessary to identify the required dimensions of the opening, focusing on the doors to be installed.

Door Type Differences

The owner of the house should take into account that the doors are classified into several types according to materials and functional values.

Doors are entrance doors, they have increased resistance to external influences, and interior doors, used to separate rooms. In any case, the door is inserted into the opening using a box.

Both types, in turn, differ in several ways, the separation of which helps to avoid unnecessary costs for the acquisition of a new sample, its installation and installation.

• By location in the building: external and internal.
• Opening method: hinged, sliding (double compartments, for example), folding ("accordion"), rotating.

• According to the material from which they are made: wooden, PVC, aluminum, steel, metal, iron, glass.

• By number of paintings: single, double, one and a half.
• By the number of leaves: single-sided, double-sided.
• By filling the door leaf: deaf and blind.

Height and width standards according to GOST

It is important to pay attention to what parameters of the opening should be when installing the door or during construction. The average height is 200 cm, and in some cases - 230 cm, the minimum width is 60 cm, the average is 70 cm, the maximum is 80 cm. However, for extraordinary products, the width can be 55 cm, and the height is 190 cm. The box depth is 7.5 cm. The opening should be 5-10 cm larger than the door. This is necessary so that there is room for wooden, metal or assembly joints.

Sound insulation and reliability of the leaf depend on the thickness of the door. It, in turn, is determined by the depth of the opening.

This characteristic can have the following dimensions:

• 3.5-4cm for standard door;
• 2-4 cm for a hinged structure;
• 3.5-4.5 cm for a solid wood product, with a quadruple sample;
• 4.5-5.5 cm for a fresh wood door.

If the landlord wants fire safety to be at its best, it is recommended that you familiarize yourself with a table with specific size ratios.

It is not necessary to rely on GOST standards, because there is an alternative - foreign products. They require specific opening parameters. To understand them, it is recommended to familiarize yourself with this table:

Important settings for installation

Knowing about the standards for the height and width of the opening is not enough.

It is important to take into account other nuances that will tell you what to do during installation.

• The presence of unnecessary elements in the opening space, for example, partitions that will interfere during installation;
• use during installation of sheathing for piers or plasterboard frames;
• the need for a drywall partition, which can be recreated if necessary;
• wall material;
• wall thickness;
• casing width.

If you pay attention to the above points, you can avoid difficulties during the installation of the door to the entrance or between rooms.

How to calculate

The optimal parameters of the door leaf must be calculated in advance. There is an easy way to take your own measurements. To do this, take the door width, then add the box thickness, multiplied by two. To the resulting calculations, you need to add another 4 cm (gaps for installation and seams). When the height is calculated, the box thickness must be additionally added to it.

In the absence of a threshold, the thickness is added once, and in its presence, twice. But there are situations when you need to pick up a box that needs to be mounted in a previously used opening.

In this case, there is a certain plan of action:

• eliminate unnecessary elements at the measurement points. You need to remove not only the previous box, but also the platbands.
• Tidy up the main wall. It is necessary to remove uneven surfaces. Then you need to measure the dimensions in the largest and smallest places. Any indicator must be recorded.
• Measure the dimensions at least at two different points of the opening, especially if it is angular.
• Determine if the opening needs to be adjusted, for example, when it is skewed, or if it is too narrow.
• Test the hardness of the adjusted surfaces. If necessary, they need to be strengthened.

Cleaning the end surfaces of the opening does not always go smoothly, especially if the opening has been used before.

You can find out the height of the doorway with the threshold (in other words, with the bottom bar, which is also a part of the box) using the following formula: two box thicknesses are added to the height of the door leaf, then a mounting gap of 13 mm is added for free operation of the door from above, as well as 5 mm clearance for door operation from below.

The calculation of the height of the doorway without the lower box beam (without a threshold) is carried out according to a different scheme: the height of the leaf and the thickness of the box are summed up, 1 cm of indentation from the finished floor is added to them for free operation of the door, 3 mm of indentation is added from above and 10 mm on the mounting seam.

Another important nuance: measurements must be taken several times if the apartment or private house has recently undergone a major overhaul or redevelopment.

The wall is carefully studied and it is decided where it is safest to mount the door. No less carefully should you examine the slopes on the sides, find out what their geometry is. It is possible that they may be twisted or create other difficulties.

It will not work to make measurements with a tape measure alone, you will have to use a building level, in extreme cases - a laser builder. Measurements are carried out on the opening side from the bottom up.

Mounting Features

There are some subtleties that will be useful for both measurements and installation.

• It is recommended to take measurements when the floor is covered with something. The thickness of the carpet, for example, will help determine if the height of the door above the floor will change after the installation is completed.
• The sides of the opening should be parallel. To follow this, it is recommended to periodically measure the clearance at different points: in the center, at the bottom and at the top.
• You can measure the opening depth using a pair of rulers or a caliper. The minimum number of points for measurement is 3. This must be done by retreating 20 cm from the lower, upper and central parts of the opening. As a basis, you need to take the largest depth parameter. From it you can find out whether it is necessary to use additional parts for the box. The depth of the box must not exceed the wall depth.
• When the door frame is successfully installed, as a rule, there are gaps between the block and the wall. They can be eliminated with mounting foam, and then trims can be used as a finishing touch.

If the apartment does not have furniture that is difficult to disassemble, you can reduce the opening and put doors 70 cm wide. To do this, you need to build a drywall opening, you need to build up a metal frame, but first you need to remove the old door with a box and trim the slope. You can mount vertical racks for the box, fill the free space with the GKL.

This method is practical under the right conditions:

• The slopes are curved, and it is difficult to establish a profile on them.
• On the plaster, it is necessary to level the GKL, and at the same time, it is not necessary to reduce the wall depth.
• You can lower the passage by no more than 10 cm.

It is necessary to remove the layer of plaster at the installation site, then take the necessary measurements for the frame.

Then you need to arrange the profiles so that they stand in an even vertical position. The size of the opening must be suitable for the installation of the box. From drywall, you need to cut out several pieces and attach them to the wall with special glue and screw them to the profiles. They are connected to each other by jumpers that help maintain the gap.

If the opening is too high, this may cause a problem with the installation of the upper trim. Suitable options are to stick the wallpaper as low as possible or choose high capitals. The most effective solution is to lower the upper border of the opening using gypsum board and wooden beams, and then cover it with wallpaper.

Installation of non-standard doors is somewhat different.

The reason lies in the absence of boxes for these specimens, and hence the increased requirements for the quality of the arrangement of the end aperture sides. In addition, you will have to carefully monitor the parameters of the openings.

• The pendulum door can be mounted on hinges. Please note: when the door is opened, it deviates vertically in all directions in the region of 1.5 mm.
• When installing a compartment, the width of the box should be 10 cm larger than that of the door.
• The revolving door can move to the sides of the opening, but the gaps must be aligned along the entire perimeter.

The above samples do not have platbands that can eliminate defects. Each crevice can destroy the aesthetics of any, even the most attractive door. There are some difficulties when working with openings of pendulum and rotational specimens.

If the opening depth is exceeded by 14 cm, there will be a need for offset installation patterns for mounting hardware. If we are talking about sliding samples, then the opening thickness should be 2 times greater than the depth of the sash.

Benefits of Standard Values

Of course, the owner of the house is not obliged to adhere to the standard values, but the standards have some advantages that should be given a little attention.

• Huge variability. Most manufacturers create copies with standard parameters, so there is no difficulty in acquiring the highest quality door.
• Saving. Unlike standard, non-ordinary door leafs are more expensive. Unusual designs are ordered individually. As a result, there is a need for an additional investment of money to create a new interior.
• Easy to install. If the opening parameters correspond to the standard, then there will be less difficulties during the installation process.

Differences in dimensions by type of house

It is worth noting some nuances of sizes in different types of buildings. Usually in a "Khrushchev" or panel house, the wall thickness is 75 mm, and the door frame is made with the appropriate thickness. But if this fact is ignored, difficulties will arise. There is a need to install another expander or eliminate an extra element of the box.

Doing this at home will not be easy. In new buildings, the typical height of the opening varies from 217 to 220 cm. This is due to the fact that most owners make the “warm floor” system, and the height of the opening after installation becomes close to the standard.

The opening is created in accordance with the norms of SNiP. For a brick wall, its height should be in the region of 188-225 cm, and the width should be from 63 to 176 cm. For a monolith sample, the height is 187-225 cm, and the width is 62-175 cm. At the opening of a log house or wooden slabs height - 185-197 cm, and width - 57-170 cm.

But if you deviate from the standard and expand the sample by a couple of centimeters, the foam seam will no longer be reliable. It is necessary that the mounting foam has strength. Otherwise, she will not be able to rid the installed door of gaps and help it withstand loads. You will have to reduce the width of the opening with a wooden beam, the cross section of which is 5x5 cm. There is another option - to use a foam block and glue for tiles.

If the parameters of the box do not correspond to the dimensions of the walls, installing the casing will at least cause complications. In the worst case, the installation is excluded, and this will significantly affect the appearance of the door group. Therefore, measurements are carried out at three different points. If the resulting parameters differ slightly from each other and are identical to the standard ones, there is no need to buy unusual doors. However, there are no guarantees that after installation of a typical door, it will not be necessary to install extensions or remove the longitudinal elements of the frame.

Most often, in buildings made of brick, the walls are far from ideal, and a beam for additional timber is sometimes necessary. If you do not mount this element, the platband will only distort the wall more, and this is best avoided, since the appearance of the room will suffer, not to mention the door composition as a whole. When talking about new types of buildings, we should mention shrinkage and other changes in geometry that may occur. Do not mount the door too early. The wall can warp, and the door can jam.

The longest shrinkage occurs in newly built wooden houses. When the glued timber dries out, for every meter of the house there is a couple of centimeters of shrinkage, and when the log dries out - about 15 cm.

When overhauling or building, everything must be taken into account - even the width and height of the doors. The dimensions of the doorways, of course, can be arbitrary, but then you will always have to make doors to order. It's easier to comply with the standards - less costs and problems. The standard dimensions of interior doors are prescribed in GOST. Let it be old, but most of it is built on them.

Standard sizes of doorways

On the territory of the Russian Federation, there is still a standard from the times of the USSR, which describes the requirements and dimensions of doorways, interior doors. There are a lot of TU and DSTU, but they have nothing to do with standards - each manufacturer writes them for himself. You can buy doors made according to technical conditions if their quality is at their best. But doorways should be made exactly standard dimensions.

Why is it better to make them according to the standard? Because then there will be no problems with the replacement. Almost all manufacturers make doors in accordance with GOST. After all, high-rise buildings are being built taking into account all the requirements (or they should be built that way). If the opening has special dimensions, the doors will only have to be ordered. And these are high costs, and there is no guarantee that you will like the finished product.

Dimensions according to GOST

So, even with a major overhaul or construction of your own house, during the construction of interior partitions in a new building - in any case, we lay standard doorways. GOST provides for the following parameters:

• Width:
  • Single leaf 700 - 900 mm (in 100 mm increments) and 1200 mm. In such doorways, it is recommended to install doors with single-leaf canvases.
  • Under double-leaf (the term double-field canvases are used in the standard), openings are made with a width of 1300 mm, 1500 mm and 1900 mm.
• The standard height of the doorway can only be in two versions: 2100 mm and 2300 mm. The minimum allowable height is 2071 mm and 2271 mm, respectively.

These are the dimensions of standard doorways. No others. As for tolerances, the doorway can be narrower than the standard by 20-25 mm. In this case, it will also be possible to install a standard door block. Only the mounting gap will be smaller, which will not facilitate the work. That is, the narrowest doorway can be 675 mm (instead of 700 mm). According to the same principle, the tolerance can be calculated with respect to each standard width. It can be slightly reduced, but not more than 25 mm.

What to do if the actual dimensions do not meet the standard

What to do if a few millimeters are not enough to meet the standard? Depends on the material of the walls, as well as on the actual width of the passage. If the walls are machined, you can remove a few missing millimeters. Chop, grind, cut down. An ax, a chisel, a chisel, a grinder with a disc for concrete / brick, etc. Usually a couple of protrusions or curvature in some area interferes. If you align it, you can get closer to the desired size.

If the walls are made of very strong material, the only way to fit the opening to the standard is to reduce it to the next standard value. There are two ways: lay bricks, pieces of building blocks, plaster. The second option is to install a mortgage beam (treated with an antiseptic and dried), which, again, is covered with plaster, aligning it with the walls. In general, you understand the idea: it is more practical to bring non-standard dimensions to the standard.

Convenient sizes of interior doors

The height of the doorways is easier to determine. Everything is tied up at the height of the ceiling. Yes, and the choice is small - only two options - 2.1 m and 2.3 m. But what about the width? There are more opportunities here. In general, there are certain recommendations that relate to the minimum dimensions of doors. It is the doors, not the openings for them. The opening should be 70-100 mm wider. So, the dimensions of interior doors should be no less than the specified width:

• In technical rooms (pantries, bathrooms, baths and toilets), the recommended web width is 600 mm.
• For kitchens, the minimum is 700 mm.
• For living rooms, at least 800 mm is recommended.

Of course, you can increase the size of interior doors if the doorway allows. Reduce - at your discretion. But the narrowest door leaf that can be found on sale is 550 cm, and even then it is inconvenient for obese people with it. In the kitchen and the room where gas equipment can stand, the width of the doorways is dictated and controlled by the fire department. So it can no longer be done. Wider possible.

As for residential premises, openings can also be made in them for double doors. That is, up to the maximum permitted in GOST 1.5 meters. There may be wider ones, but this is already non-standard. In a wide opening, you can install not only conventional swing models, but also or. But large and wide doors look good in large areas. So the recommended sizes of interior doors are chosen for a reason. They took into account not too large rooms in our homes.

How to determine how wide the door leaf should be installed

If the doors are just going to be replaced, the easiest way is to measure the canvas that is already standing. So you definitely can't go wrong. If you will be installing doors for the first time, you need to measure the doorway and choose an option under it that will require minimal effort during installation.

How to measure a doorway

To choose the right size for a door or door unit, you need to know the exact dimensions of the opening in which they will be installed. Measurements are carried out using a conventional construction tape measure. Any parameter is measured at least at two points. If the difference is visually visible, you can measure more times, adjusting the position of the tape measure at your discretion.

The height of the doorway is measured at one and the other jamb, the width - at the top and bottom, approximately at a distance of 30-50 cm from the floor and the lintel. You can take measurements in the middle of the height. You also need to measure the thickness of the opening (wall thickness). It must be checked at least at two points on each side.

All measurements are recorded. It is better to do this on the doorway diagram. If there are deviations, we look at how serious the situation is and whether it can be corrected. If the bottleneck corresponds to the smallest possible standard opening, you can leave everything as it is. Otherwise, it will be necessary to try to correct the situation. It has already been described above.

But size isn't everything. It is necessary to check whether there are deviations in geometry. The side walls of the doorways should be vertical, and the lintel - horizontal. You can check the correctness of the form using the usual building level (bubble), but it is more convenient and more accurate using. You can check the side walls with a regular construction plumb line. If the deviations are large, they must be corrected. If their value is within a centimeter, it will be possible to compensate during installation using mounting plates and construction foam.

We select the sizes of interior doors and blocks

As already mentioned, the dimensions of interior doors are determined based on the dimensions of the existing opening. Doors are sold as a block complete with a box or only one leaf. It is more convenient to take the block - this speeds up installation. But buying a separate canvas and assembling a box will be cheaper. Here you choose either to pay less, but spend time and make extra efforts, or save time, but spend more money.

If you decide to buy a door block, make sure that its width (according to the outer dimensions of the door frame) is slightly less than the width of the opening. The minimum mounting gap is 10-15 mm, the optimal one is 25-35 mm.

When buying only a door leaf, it is assumed that it should be 80-100 mm narrower than the opening. It will be necessary to add two more jambs, and this is at least twice 25 mm each, plus a mounting gap of 10-15 mm, plus a gap on the sides of the door leaf - 5 mm. Total we get: 25 * 2 + 15 + 5 = 70 mm. This is the minimum value that must be added to the width of the door. The resulting figure must be equal to or less than the width of the doorway in which it will be installed.

Entrance door dimensions

The dimensions of the entrance door openings are also normalized. They are described in GOST 6629-88. If you want to install standard products, make openings according to the recommendations. If you are building your house, it is better not to lay the entrance doors less than the minimum width. And it's not just the difficulty of finding the right dimensions for the canvas. The fact is that there is a very high probability that the fire or gas service will force you to redo it.

Firms have their own standards for technical specifications

So, the standard dimensions of the entrance doors can be:

• web width
  • for single-leaf - 900 mm, 1100 mm;
  • for double doors - 1400 mm (700 mm + 700 mm); 1800 mm (900 mm +900 mm).
• canvas height - 2300 mm.

If we talk about what is on sale, then there are any doors. Moreover, you can order - iron or wood of any thickness. But again, this is non-standard. Although, the entrances are changed much less often than the interior ones.

A few words about what should be the doorway under the front doors. According to the same standard, it should be 70 mm wider than the leaf for single leaf doors and 72 mm wider for double leaf doors. These are the minimum values. A wider opening is possible, less is not. The height of the doorway for installing the front door should be 71 mm larger. That is, under the front door with a leaf 900 mm wide, you need an opening of at least 970 * 2371 mm. With the rest it is similar.

As a layman, we rarely come across a choice of interior doors. If such an opportunity occurs, most often we cannot choose the right interior door and correlate the dimensions of the door block, door leaf and doorway. In this article, I will show you how to choose an interior door, including without seeing the door visually, that is, in an online store.

Sale of doors in online stores

Selling doors through online stores has become commonplace of our time. On the one hand, it is convenient, you don’t need to go anywhere, a lot of shops are within the reach of a “click”. On the other hand, there is no visual contact with the goods and it is not easy to figure out the dimensions of the doors without a cheat sheet.

It’s good if there is an online consultation on the store’s website, and the price tag is formed without cheating, taking into account all the elements of the door. The last time I dealt with the online store Tudoor.ru. Unlike their counterparts, this store provides a complete door calculator, taking into account all the necessary elements, without which the door cannot be installed and function. Already at the first stage of selection, they explain to you that an interior door is not only a canvas and a box, but also hinges, a lock, platbands or platbands with an extension, the quality of which determines the quality installation and long operation of the door. Look more information on the site tudoor.ru, you will like it.

However, you can not come to the store's website without having any data at all, which door you need. And here I DO NOT mean the quality characteristics of the interior door:

• Cloth deaf or with glass;
• Door leaf made of solid wood or paneled;
• If the canvas is paneled, then with what kind of filler (cardboard or timber);
• How is the canvas finished with natural veneer or film or MDF or other modern material;
• Which door frame is offered to the canvas, from solid wood, glued laminated timber or MDF.

Here I am talking about the right choice of door sizes.

How to choose the right interior door size

To begin with, in order to speak the same language, let's remember that the interior door in the kit is called a door block. The door block consists of the following elements:

Door leaf. The movable part of the door, which performs the main function of the door, opening and closing;

Door frame. Consists of three or four strips. Two vertical posts, one upper crossbar and an optional element of the lower bar - the door sill.

Door fittings. Special decorative elements that should cover the ends of the doorway, if they are wide, the width of the box.

Door frames.Decorative strips designed to close the mounting gap between the box and the opening.

door latch or a castle.

Door hinges. There are universal, right or left. Also collapsible or not detachable.

Do not forget about the doorway, the dimensions of which are the starting points when choosing a door by size. Namely, with the correct measurement of the opening, the correct choice of the door begins.

How to properly measure a doorway

Singing in the interior partition, designed to install a door, is called a door. In standard apartments, it has standard sizes. However, you can always expand or narrow the doorway for the planned door.

You need to measure the doorway in three parameters: width, height and thickness.

opening width must be measured along a horizontal line from edge to edge.

Opening height. There are two points here. The interior door can be installed both before finishing the floor and after finishing. Both options are eligible. If the door is planned to be placed on the subfloor, then the height of the opening is measured from the subfloor to the top of the opening without gaps. If the door is placed on a finished floor finish, then it can be taken into account that the frame should be 5 mm apart if the finish is floating (laminate, board) and 2-3 mm if the finish is monolithic (tile). Usually this gap is taken into account when installing the door and it does not affect the height of the purchased box.

opening thickness. This amount is needed to purchase add-ons. If the thickness of the opening is 75 mm, then this is the width of a standard box and extensions are not needed.

Choosing a door according to the size of the opening

So, we have the dimensions of the doorway, how to choose the right interior door. Here's a little cheat sheet to help you. Clearances must be of the following values

• The gap between the canvas and the box should be 3 mm on each side;
• Between the canvas and the finishing floor 10 -15 mm;
• Between the box and the subfloor 0 mm;
• Between the box and the finished floor 4-5 mm;
• Mounting gap between the box and the opening is 20 mm on all sides except for the threshold (if any);
• Mounting gap between the door threshold and subfloor 0 mm.

Reverse calculation of the width of the opening according to the width of the canvas

There are standard sizes of door panels, according to which you can calculate the desired width of the doorway. This is the width: 600/800/900 mm and swing 1200 mm. The height of the canvases is 2000/2200/rarely 2400 mm. Box width 25 mm.

If we add these values ​​​​and add to them all the gaps from the cheat sheet, we get that for a door leaf of 2000 × 800 mm, we need a doorway of 2100 × 900 mm (rounded up), a box without a threshold.

Calculating the cost of a door online is very useful, you will immediately see the costs. And our calculator will do it without problems. All the work is done with your own hands online and you only need to know the right dimensions and material of manufacture.

Working with the calculator

First of all, you need to decide on the shape of the doors. Will it be deaf or do you want to do it with glass.

• We take the required dimensions. In this case, it is necessary to carefully measure the diagonals, because the geometry of the structure must be ideal;
• Now we make a choice of finishing material. It’s worth saying right away that natural finishes will always cost more;
• We tear out the size of the insert from the glass (if there is one). At the same time, we take into account that there will be a step for fastening;
• We measure the width of the platband. The price will depend on its width. It should also be noted that it overlaps the joint. And if your opening is not even, then this error will have to be taken into account.

Here you can make a calculation of the cost of plastic doors and made from natural materials. Videos and photos will help you make the right choice. On our site you can find articles on the manufacture of any design yourself. You just need to go to the right section and read.

Sections of the article:

Carrying out major repairs in a house or apartment in most cases ends with the installation of new interior doors. However, it is at this stage that the greatest difficulties often arise. The reason for this is the dimensions of the doorway, which often have a lot of errors in the form of wall curvature and non-compliance with GOST dimensions of interior doors. Therefore, in order to successfully complete the replacement of door structures, it is worth familiarizing yourself with the recommendations of GOST and the permissible changes in the dimensions of the openings.

Standard dimensions

It is quite important to distinguish between them according to their functional affiliation in order to determine the appropriate dimensions of the doorway. The size of the opening leading to the technological premises by the type of bathrooms may have slightly smaller dimensions than for ordinary interior doors.

• Height;
• Width.

The thickness or depth of the passage largely depends on the material of the walls and the conditions of construction, therefore they are not significant indicators.

Height

The height of the doorway for bathrooms can be from 1.9 to 2 m. The same applies to the bathroom. Kitchen aisles in most cases have a height of 2 m. For other rooms, the norm is 2 - 2.1 m. According to calculations, this is enough for comfortable movement of people with an average height of 1.7 m.

However, passages with a height of 2.2 - 2.3 m are often found. Such dimensions are explained by the ratio with the height of the ceilings. In most apartments, which have a floor-to-ceiling distance of no more than 2.6 - 2.8 m, the best option is the standard size of 2.1 m.

The main condition justifying the increase in the standard height of doorways is the need to move large pieces of furniture.

Width

According to GOST, the standard width of a doorway intended for installing an interior door, when using single-leaf structures, has an average size of 0.7 to 0.8 m. Such parameters are justified by average statistical data on the dimensions of an adult.

At the same time, the permissible width of passages for bathrooms and toilets can be from 0.55 to 0.6 m. The use of double doors for living rooms and bedrooms allows an increase in the width of the doorway to 1.2 m.

Non-standard dimensions

Currently, non-standard sizes of doorways are much more common than those prescribed in GOST. This trend is due to the desire to bring more functionality and convenience to the house, as well as highlight the individuality of the created interior style.

Most often, redevelopment lends itself to the width of the doorway in the living rooms. At the same time, the increase in parameters is carried out by more than 1.5 times. So, in an effort to add a feeling of large space, often instead of the usual single-leaf swing door of 0.7 m, the size of the opening increases to 1.6 m and a double door is installed.

Due to the presence of large furniture and with sufficient dimensions of the rooms, as well as if you want to give the room a visual expansion of space, the opening for the interior door can be expanded and have dimensions of up to 1 m. In this case, both a swing wide door and sliding door systems with one or two doors.

However, there are frequent cases of redevelopment of interior passages by reducing their width. Such actions are also allowed. But with any changes in the existing passages between the rooms in the direction of their narrowing, it is necessary to rely on the requirements of evacuation and fire safety. The main condition for compliance with these requirements is the unhindered movement of people in emergency situations.

arched doorways

Arches can be attributed to certain types of doorways. This gradation is due to the peculiarities of their designs. In the absence of the door leaf itself, the width and height of the openings can expand significantly. The main condition for redevelopment is the change of walls that are not load-bearing structures.

However, even for arches there are some engineering limitations that directly depend on the type of arched structure.

Types of structures

Arches are conditionally divided according to their shape into the following types:

• Rectangular;
• Classic;
• Ellipsoid;
• round;
• Semi-arches;
• Eastern;
• Asymmetrical.

The size of the opening of a rectangular arch in most cases is almost identical to the dimensions of the passage for a standard interior door in height and averages 2-2.1 m. 2 - 2.3 m. At the same time, the width in most cases does not change and is standard 0.8 m.

Despite some narrowing of the rounding of the ellipsoidal arch, the parameters of the doorway for its installation change significantly. So, the width is about 1 m, while the height of the passage can reach almost to the ceiling and have a maximum allowable value of 2.5 m. Such drastic changes are necessary, since with standard dimensions a passage of this shape will look ridiculous.

Round structures, like ellipsoidal ones, require significant changes to the walls. The minimum width with such an arched opening is 0.9 m, and the height, due to the large radius, also approaches the maximum technologically permitted value of 2.5 m.

A semi-arch and an eastern-type opening in most cases do not require a change in the width of the passage at standard values ​​​​of 80 cm. But asymmetric structures can have the maximum allowable width and height parameters.

Features of calculating the dimensions of the doorway

When choosing doors, it is very important to correctly calculate the dimensions of the opening. Thus, the installation of the structure can be greatly facilitated. Accurately selected height and width of the product allows not to alter the opening for the interior door.

It is important to remember that when calculating in newly built buildings, possible shrinkage must be taken into account. The timing of such processes directly depends on the materials from which the walls are made. Wooden buildings are subject to the greatest changes. At the same time, ordinary glued beams can decrease by up to 2 cm per meter of height. Logs settle up to 15 cm per 1 m.

The installation of various types of door structures can significantly affect the width of the passage. A sliding coupe door requires a width margin of about 10 cm. A roto door, due to the complexity of the mechanism, also requires an additional niche that reduces the width of the opening to accommodate fasteners.

Finishing work carried out in rooms can also significantly affect the size of the doorway. So, laying a simple, not insulated linoleum takes about 1 cm in height. Laminate reduces this figure by 2 cm. In the case of laying tiles or porcelain tiles on the floor, the height of the doorway will decrease by 3–5 cm. Laying a warm floor can take an additional 7–10 cm.
