The width of the front door frame. Dimensions of metal doors: what is important to know. How to calculate a doorway

The feeling of security is created by entrance metal doors, and they must meet the following requirements:

• reliability and aesthetics;
• ease of use;
• fire safety;
• high-quality sound insulation;
• long service life.

Can install Russian or imported door.

Installation of a domestic metal door

In Russia, they are made by professionals with extensive experience in this industry. On modern technological equipment, a box is made of a one-piece molded profile with a stiffening rib, which prevents the door from deforming during operation. Included with the canvas are necessarily porches and platbands. The platband is needed to close the gaps after installing the door frame, and the gap between the door leaf and the frame is closed with a porch.

It is possible to produce input steel doors not only standard sizes, but also to order, taking into account all the wishes of the customer: dimensions, metal thickness, materials for heat and noise insulation, fittings, exterior and interior finishes. Performance of work in the execution of a manufacturing order is not standard door costs the customer much more. Their size is determined, as a rule, by two values:

• canvas dimensions;
• opening dimensions.

Building Blocks metal doors for residential and non-residential premises are defined by GOST 31173 - 2003. The document clearly describes all the most important parameters that must be observed in the manufacture of steel doors produced in the Russian Federation.

Steel sheets in the manufacture must be welded together with strong seams, without cracks and sagging.

Door opening dimensions

A door frame made of a flexible profile must be at least 1.5 mm thick. The thinner thickness used can lead to deformation door leaf. Then you need to repair or replace the canvas. If a rectangular profile is used in the manufacture, then its dimensions should be 40x50 mm.

In modern panel housing construction, they are prescribed in the master plan for development and should be:

• width - 740-760 mm;
• height - 1950-1980 mm.

In houses built of brick, the following are considered acceptable:

• width - 880-929 mm;
• height - 2050-2100 mm.

Typical series of houses built at the end of the last century had doorways:

• width - 830 - 960 mm;
• height - 2040 - 2600 mm.

In modern housing construction, building codes and standards are not always maintained. Each firm strives to outdo the competitor in providing even such small conveniences as larger doors. You can, of course, buy a standard one, providing quality installation its complementary materials.

Non-standard dimensions of the opening must be measured. Completely remove all overhead parts old door and clean the opening from debris and crumbling plaster. It is necessary to check the verticality of the opening walls with a plumb line and measure the distance between the walls, the floor and the upper point of the opening.

Metal doors must have a strictly geometric shape: height, width and diameter. A deviation of 3 mm is allowed. The design must have a high quality outer coating. If external or interior decoration does not correspond to that specified in the sales contract, the customer may request that the product be replaced.

Heaters for metal doors

The canvas can be hollow, or, at the request of the customer, be filled with an insulating material that reduces heat loss and increases sound insulation.

For this are used:

• mineral wool;
• polyurethane foam;
• polystyrene, etc.

Such soft insulation as mineral wool must be isolated from the metal surface with a layer of waterproofing.

This layer is necessary to isolate the condensate that forms during temperature changes. Mineral wool filled with vapor condensate can cause significant damage to a metal surface, even if it has an anti-corrosion coating.

Rigid insulation is inserted into the canvas tightly, without gaps.

Bulk insulation can also be used, but only if crossbars are not installed inside. Otherwise, they will be blocked.

External insulation of metal doors is not required.

The door frame is insulated mounting foam or loose insulation is poured through the drilled holes.

All materials used for heat and sound insulation must meet the requirements of sanitary safety. In addition, a rubber seal is laid along the perimeter of the door frame, and a magnetic seal is laid along the edges of the door leaf, which increases the fit. With the help of the installed eccentric, the tightness of the door leaf to the frame is adjusted.

Finishing metal doors

External and internal finishing of metal doors can be various. Russian manufacturers offer many finishes that are of high quality:

• vinyl artificial leather of Russian and foreign production;
• Genuine Leather;
• laminated wood panels;
• powder thermal spraying;
• MDF panels covered with PVC film or veneer or painted in any color, 8 or 16 mm thick, with any milling pattern (even according to the client’s sketch);
• paneled (with fine wood trim);
• installation of double-glazed windows is possible;
• it is possible to use forged elements, embossing, stained-glass windows, automatic and manual wood carving, stone inlay, various kinds artificial aging.

Decorative trim used in the manufacture must be made of quality materials and have a strong bond with the base. Facing parts made of wood must be completely covered with varnish or other protective material and have a small area of ​​contact with metal.

Door hinges and locks

When mounting hinges on metal doors, anti-removable pins are installed. By welding or riveting, they are fixed in the frame of the door leaf or door frame.

They are installed from 2 to 5 pieces. The more you install them, the more holes you need to drill. And this leads to a decrease in performance.

For greater security, manufacturers recommend installing 2 various types locks: level and cylinder.

Lever locks have a complex system of protection not only from unauthorized opening of the door, but also from its drilling.

Cylinder locks are easy to operate, extreme situations it is possible to replace not the entire lock, but only its part - the cylinder. In it, the plates are arranged in a combination that makes it possible to open the door only with the key intended for this lock.

- the first thing that guests see and at the same time your main protection against intruders and ill-wishers. Therefore, the choice of this element should be approached with attention, taking into account all the recommendations of specialists, as well as the requirements and standards of GOST. Consider what the front door can be: dimensions, design features and basic manufacturing materials.

In the vast majority of cases, it has a greater width than all other openings in the house. As for the design, it can be the most diverse, and in this matter the only limitation is the manufacturer's imagination. The most popular materials for making entrance doors metal, wood and MDF are considered.

There is no relationship between the material of manufacture of the door and its size, so exactly the same requirements apply when choosing. Be sure to take into account a number of design features, which, however, are not related to the material.

The easiest way is to divide the doors into groups depending on what design they have:

• single-leaf doors are familiar to everyone and you can even say standard version, which is a canvas inserted into a frame. Usually the width of such a door does not exceed 100-110 cm. A single door can be the most ordinary and simple, or it can become the realization of all the most daring design ideas, truly decorating the house;
• bivalve doors are usually used in private houses, since with a standard opening height, the width of the door increases by about 1.5-2 times. This is certainly a more convenient option, however, its implementation requires a lot of free space on the sides of the house;
• transom doors. For such a solution, you will need to increase the height of the doorway. Moreover, the door leaf can remain standard, and the upper part of the structure is fixed separately, without harming the structure. In most cases, decorative glass inserts are used for this purpose, since they serve additional source light and allow you to visually lighten the design of the door.

Helpful advice! If what you really want is impossible to establish, and available options you are not satisfied, you need to think about alternative options. For example, one-and-a-half doors are an excellent compromise if there is not enough space for double doors. In this case, one of the canvases is smaller and serves as a decorative insert.

Standard door dimensions: Main settings

Regardless of which type of construction you decide to give preference to, the standard dimensions of the front door are the parameters that you need to familiarize yourself with in any case:

1. Front door height. Usually for a standard door, the opening height is about 2070-2030 mm. But it is necessary to determine the exact value individually, resorting to measurements.
2. Front door width. The minimum width of the front door, which can be - 900-910 mm, there are also single-leaf doors - 1010 mm. One and a half doors come in different widths - 1310 mm, 1310 mm and 1550 mm. Double doors are usually noticeably wider - 1910 and 1950 mm.
3. Door thickness. There are no standards in this case, since the thickness of the leaf is determined by the material, as well as some design features of each specific product. But, despite this, you need to understand that the thickness of the door must be sufficient so that it copes with its main task - protecting the house. It is for entrance doors that the thickness of the leaf matters the most. It is believed that if we are talking about a metal sheet, then its thickness should be at least 2 mm, but otherwise you can focus on your own preferences and opening parameters.

Schematic representation of dimensions

The front door should usually be larger than all the other doors in the house or apartment, as this will not only allow you to freely enter the house, but also, if necessary, bring in loads.

Is it possible to useentrance doors of non-standard sizes

In many modern houses, especially if they were built according to individually developed projects, GOSTs are simply not taken into account. But the recommendations of SNiP are highly discouraged, although in many cases they are also bypassed. So in a private house, you can use any doors of non-standard sizes.

Of course, you will have to agree on the dimensions of the front door to the house with standard indicators, but there is no need to accurately compare the indicators. It is enough to try to maintain the ratio of the elements to each other, and all the necessary measurements can be made right at the construction site.

The size of a metal front door or a wooden structure can reach 900-2000 mm in width and 2000-2400 mm in height. Expanding the doorway further does not make sense, unless we are talking about building a residential building, but about a public institution, for example, a small hotel, cafe or a very large house.

How to choose entrance doors with a frame: dimensions and designs

It is extremely important that the dimensions of the iron entrance doors or the leaf made of any other material are correctly correlated with the opening. First of all, it should be possible to place the box in the opening without problems in such a way that there are small gaps around. This free space will allow you to set the structure as evenly as possible, and the gaps can be easily replaced. This is a great option, however, it is far from always available, since it is assumed that the doorway is initially perfectly cleared and it is possible to make all the necessary measurements.

Well, as for the correspondence of the box and the canvas, it is best that these two elements are initially included in the kit. So, you can avoid the problems associated with their mismatch. If we talk about the separate acquisition of these elements, then you need to select the canvas very carefully, not forgetting that it must be smaller than the opening, otherwise the box simply will not fit.

For the rest, you just need to try to provide gaps of at least a few millimeters so that the movement of the door is not limited in any way.

• opening method also has great importance. Of course, this largely depends on the size of the front door. In a private house, for example, there are much fewer restrictions, but in apartments you have to adapt to the situation. The size of the door in this case should be such that it can be opened without problems, and the passage on the site is minimally limited;
• The outer finish of the door is also of great importance, since it performs a protective function and prevents the loss of functionality and attractiveness. appearance doors as a result of exposure to various temperatures and mechanical influences. Powder coating and oak paneling proved to be the best in this matter;
• noise and heat insulation is another mandatory criterion. For soundproofing and insulation of the front door is usually used mineral wool or polystyrene foam;
• security system - something that protects the door from breaking and the visit of unexpected guests. In addition, attention should be paid to the quality of the fittings used, since they determine not only the attractive appearance of the door, but also its reliability.

Helpful advice! An ordinary household door can be equipped with a lock of 1-4 burglary resistance classes, but you need to understand that this is not the most important point and the strength of the door itself must also be appropriate. After all, there will be no sense in a reliable lock if the door itself can be easily knocked out with one blow.

Best inputmetal doors: dimensions with boxand without, characteristics

Each entrance door stands out among others with some special characteristic that allows us to call this model the best. Consider several options for doors that, for one reason or another, were named the best.

1. The best door with a thermal break is the North. This door can provide reliable protection from the cold even at outdoor temperatures down to -40 degrees. All places that are considered problematic for entrance doors are perfectly sealed in this case. Such a door weighs a lot - 100 kg, however, due to high-quality polymer-powder coating, the design does not look heavy and bulky. With proper care, this door can last for many years. The width of the entrance door to an apartment of this model can be 860 mm or 960 mm, and the height is always standard - 2050 mm. The thickness of such a canvas is 80 mm.
2. Akron 1 is best door, which can only be found for installation in an apartment. As already mentioned, apartment owners are much more limited in their choice, and you need to understand that the size of the front door in Khrushchev will not allow you to roam. This model is a great combination. small size, reliability and attractive appearance. The thickness of the door leaf is 65 m, and there are also 2 sealing contours. The design is equipped with a Guardian 10.11 lock of the second class of burglar resistance. Mineral wool is used to provide heat and sound insulation.
3. Arma Standard-1 - a door made of bent metal profile, which has stiffeners, due to which the structure is more dense. The complete set of this door has everything you need: a peephole, fittings, a cylinder and lever lock. There is also an additional protection against burglary - anti-removable pins. From exposure external factors the door is powder-coated, which provides it with reliable protection. With a leaf size of 880x2050 mm, the thickness of this door is 80 mm.

Able to provide reliable protection from the cold even at low sub-zero temperatures

Of course, you need to select the front door based on individual wishes, the size of the opening, as well as financial capabilities. But it’s definitely not worth saving on such an important thing, because it is it that provides you with security, heat and sound insulation from the outside world and gives you a sense of calm in your own home.

Install in country house or an apartment, a metal door is a great idea, because the product will provide reliable protection of the premises not only from thieves, but also from cold, extraneous noise, and drafts. To buy a product, you need to choose it based on the size of the opening of the entrance metal door. Measurements must be taken carefully. This is easy to do on your own, having a tape measure at hand. Or you can call a measurer from a company that installs doors. Next, consider what are the dimensions of the entrance metal doors, and how to correctly calculate all the parameters of the input structure.

The product has several parameters that should be considered when buying and installing. These include the geometric dimensions and weight of the canvas. The mass of the sash, in turn, depends on the width and height, as well as the thickness of the metal sheets.

Typically, the weight of entrance metal doors of standard sizes is 70-80 kg. If the product is too light, has a mass of 50 kg or less, then you should not buy it. Such a canvas is not durable, it can be easily opened.

Two types of metals are used for the manufacture of doors: aluminum or steel. The first is lighter and the second is stronger. Also, when choosing products, it is worth considering the purpose of the input system, its type, and design features.

The door kit includes:

1. Box It is performed in the form of the letter P, if necessary, supplementing with a threshold. Made from metal corner. The thickness of the metal door frame is usually 80-90mm.
2. sash. It is made in the form of a canvas, represents sheets of metal soldered together.
3. Stiffening rib. They protect the structure from warping, twisting and other deformation. They can be transverse or longitudinal, often both types are combined.
4. Interior and exterior finishes wood boards, MDF or plastic panels, paint, artificial leather).
5. Insulation. It can be located inside the canvas or outside under the finishing material, for example, leatherette.

In addition, all accessories are included in the kit. It includes hinges, locks and other locking mechanisms (latches), eyes, closers, handles, rubber seals.

If it is necessary to mount a door in a country house, before buying it, you should think about arranging the visor. It is better to order it right away. This simple device will protect the canvas from precipitation and direct sunlight, thereby reducing burnout.

How to take measurements yourself?

To choose a metal door in a store or order it on the Internet, you should first calculate the dimensions of the entrance metal doors with a frame. You need to approach this issue very responsibly. If there is a plan for an apartment, then the dimensions of all openings on it are indicated. However, it is better to double-check them with your own hands in reality. After all, over time, any structures shrink.

Sizing process of iron door with frame:

1. First you need to take a ruler or tape measure. It is easier to work with a tape measure, it is more convenient, it allows you to measure large quantities, especially for the height of the opening.
2. The old door must be removed, be sure to remove the threshold. It will not be superfluous to check the curvature of the opening with the help of a level. If the distortion is significant, then first you need to align it. Otherwise, the new product will not function normally, it will wear out, and the locks will not close well.
3. To obtain the width of the door, you need to measure the distance between the verticals. All parameters are written in millimeters. Measurements need to be done several times in height, preferably 3-4 times, choose the minimum value. It is important to remember that the width of the opening is not the width of the sash, because a box is also installed in the aisle. It is between its verticals that it is necessary to make measurements.
4. In the same way, measurements are made 3-4 times between the upper and lower levels. Record the lowest height value.
5. Measurements must be accurate. After all, if the product turns out to be smaller than the opening, then you will have to think about how to fill it. When the canvas is larger, you will have to expand the passage. One way or another, errors cause a lot of inconvenience and problems.

The door leaf can have standard sizes or non-standard. In the first case, the choice of models is quite large. Standard sizes of iron entrance doors, as a rule, are found in apartments, since most of them are built according to standard designs. In the second case, you will have to order the manufacture of the sash according to individual parameters.

Non-standard sizes of openings are more typical for country houses, non-residential premises. Their production will cost more than typical products.

Also, when taking measurements, it is necessary to take into account in which direction the sash will open. If out, then in apartment building it should not block the passage on the stairs, the entrance to neighboring rooms, and so on. That is, it is necessary to pay attention to the usability of the design.

Standard sizes

According to GOST, the standard dimensions of entrance metal doors can be as follows:

• the width of the doorway can vary from 70 to 1540 mm;
• the height should be 2055-2060 mm, here the difference is not so big.
• the thickness of the canvas must be 75 mm.

The most successful is the width of the opening in the range from 900 mm to 1000 mm. The height in most cases is taken as 2 meters. Most often, those products that are found in stores have a width of 800-900 mm. According to the standard, the dimensions of the box should be approximately 6-7 cm larger than the parameters of the sash. The parameters of the block in this case will be 870 mm and 970 mm, respectively, and its height is 2070 mm. The deviation should not exceed 10 mm, in extreme cases - 15 mm.

In addition to these characteristics, we must not forget that the threshold needs a height of 25 mm to 45 mm. A higher one is not equipped so that people in a wheelchair can overcome the barrier or a baby carriage, it can be easily brought in or taken out of the house. And in order to install the box, the size of the opening for the metal door should be 1-2 cm larger than the box. These gaps are blown with foam after installation.

Single and double leaf models

The height of structures can vary from 2 meters to 2.3 m. In some cases, transoms are equipped in the upper part of the opening. This is typical for a private house, where the size of the opening for the entrance iron doors too big. They don't have to be rectangular. The arched shape with stained glass windows looks beautiful in a country house.

As for the width, for different types it differs:

1. Single-leaf structures are equipped with one canvas. It can be narrow at 600mm or 650mm wide. Such models are mounted in typical premises, technical, warehouse. Standard canvases are more common.
2. Bivalves can have both working full or only one, they are also called one and a half. They have one part, narrower, closes tightly and opens only when necessary. The width of one-and-a-half doors is 1200 mm with a working part of 800 mm, as well as 1400 mm with dimensions of the working canvas of 800 mm or 900 mm.
3. For double-leaf doors, both leafs are the same size, they are equally functional. Each leaf will be 600, 800 or 900 mm wide.

Door thickness

Metal doors can be made simply from a sheet of metal (cold version) or in the form of a frame with insulation inside. Apply sheets with a thickness of 1.5-2 mm. The smaller one is unable to provide structural strength, protection against burglary. Sometimes it is increased to 3 mm. Thicker metal is not used so as not to significantly increase the mass of the door. The exception is bulletproof products, fire-fighting, they require reinforced hinges that can withstand the appropriate weight.

The thickness of the sheet in the manufacture of conventional, standard insulated sheets ranges from 60 mm to 80 mm. If the products are of a reinforced class, then this indicator will start from 80 mm and reach 100 mm.

This setting is affected by:

1. Sealant, its dimensions. This is a rubber contour, which is located around the perimeter of the canvas. The seal provides a stronger fit of the sash, as well as the tightness of the structure. 2 or 3 circuits are mounted on the door, then the total thickness of the door will be 80 mm.
2. Insulation. Up to 25% of the heat leaves the room through the door. Several layers of insulation are mounted in the canvas, their number and density of the material determine the thickness of the sash.

Strengthening the door, increasing its thickness should not be thoughtless. The maximum weight of the structure cannot exceed 200 kg.

Norms of other countries

In the EU countries, there are standards for the size of entrance metal doors, called DIN. For the manufacture of metal doors, rather light steel is often used.

IN different countries the concept of "standard size" may differ:

1. Products from Spain are produced with a width of 600-1000 mm.
2. Canvases from France have a different width: 690-990 mm.

Therefore, when installing imported products in a domestic opening, it will have to be significantly altered (increased or reduced), depending on the size of the steel doors with a frame. Also, various brands have completely different term product warranties, you should pay attention to this when buying a product.

Most of the door models that are produced in China are the same size as our GOSTs. But their performance is not always "on top".

In order to avoid any hassle with the installation of a metal door, you need to correctly calculate the dimensions of a metal door with a box: height, width, depth. If you plan to order goods along with installation, then it is easier to entrust this matter to the measurer. With self-purchase and installation, you can do all the measurements with your own hands using a tape measure.

Steel systems according to GOST 31173–2003 consist of 2 parts: an outer box, which is a static rectangular frame, and an inner leaf, which opens and closes during operation. These structural nodes have many characteristics, including dimensions. If these indicators are important for the sash, when an overall sofa is brought into the house or apartment. - Then the dimensions of metal doors with a frame, more precisely, the width and height play a role at the installation stage - the structure must enter the opening, and with minimal gaps. When choosing a block, these parameters are taken into account first of all, which can be both standard and arbitrary.

Standard sizes

Entrance systems are structures in which the dimensions of the canvas, box and opening are completely dependent on each other. All these parameters are standardized and, if necessary, the width and height of one element can be used to easily calculate the geometry of 2 others. If the standard parameters of a 1-leaf sash are 2.0 × 0.6 / 0.7 / 0.8 / 0.9 m, then the corresponding size of the door frame of a metal door is 2.071 × 0.67 / 0.77 / 0.87 / 0.97 m. It is obvious that the outer element is longer and wider than the inner one, respectively, by 71 and 70 mm. This principle also applies to 2-floor standard models: 2.0 / 2.3 × 1.202 / 1.402 / 1.802 m versus 2.071 / 2.371 × 1.272 / 1.472 / 1.872 m.

Similarly, the geometries of openings and frames are interdependent, between which mounting gaps of 15 – 20 mm are arranged along the perimeter. The former are diverse, since buildings erected both 1 year and 20, and 40, and 100 years ago are in operation - it is not surprising that various building standards were in effect at different periods of time. Modern steel systems, presented in the Dvermet MSK online store, are dimensionally suitable for niches in houses of any age.

On modern market the most popular systems: 0.88 × 2.07 m and 0.96 × 2.07 m. They fit well into most entrances. Or without affecting the reinforcement, they allow you to increase the niche.

Custom sizes

If for apartments it is almost always possible to choose standard sizes of entrance metal doors with a frame, then with private houses the situation is slightly different. These buildings are often built according to special projects, so the geometry of the openings is very different. Such niches are provided both for 1-leaf systems, and for 2-leaf, one-and-a-half, with side blank inserts, with upper transoms. As a result, it is not always possible to find a finished product - all that remains is to apply for individual order. It is carried out after measurements of the opening, and the final one - without slopes, plaster and other layers.

In order to obtain the results by which a block with a frame is selected, corrections are made to the geometry of the opening. When installing the product, mounting gaps of 1.5–2.0 cm are arranged on all sides. It is these numbers that are subtracted from the previously obtained data.

Dimensions of fireproof metal doors with a frame

The online store "Dvermet MSK" offers to purchase fire fighting systems DMP EI 60, which meet all regulatory requirements, including federal law No. 123. Dimensions of metal door frames: 0.85 × 2.05 m; 0.87×2.05 m; 0.95×2.05 m; 1.3×2.05 m. This product has a quality certificate.

In order to quickly and correctly install the front door, you must first choose its size, determine the type of canvas. Today, metal entrance doors are installed, which are sheathed in various materials.

In order to avoid any problems when installing the doors, it is necessary to correctly measure the dimensions of the doorway.

They can be reinforced, have a layer of insulation. in old and new houses are different, doors with one and two wings are installed.

Features of the English and metric systems of sizes

When choosing a door, it is important to immediately consider which measurement system the manufacturer uses. Today, metric and English are used. The English system uses the unit of measurement - feet. For example, a standard opening has a height of 6 feet 8 inches or 203.20 cm. At the same time, the width is 2 feet and 9 inches, translated into familiar units of measurement, it is 84 cm.

The metric system is characterized by standard parameters:

• 2170 * 700;
• 2419 *1910;
• 2040*826 for normal wooden door;
• 2050 * 860 for metal reinforced.

Separately, it is necessary to take into account the presence of one or two wings.

Metal doors plain and sealed

When determining the values ​​for doors and windows, the need for reinforcement and insulation has always been taken into account. Input constructs are no exception to the rule. It is important to immediately foresee what kind of canvas is needed, single or double leaf, or insulated, is there a need to install additional reinforcement to protect against burglary.

Ordinary metal doors can have standard parameters:

• for a web of 850-2050 mm, an opening of 880-2080 is required;
• for 890-2070 mm, an opening device in 920-2100 is required;
• at the entrance door leaf of 970-2070 mm, the opening should have dimensions of 1000-2100;
• for a leaf in 1200-2070 (with a double-leaf door), an opening in 1230-2100 is required.

If reinforced webs are used, then the parameters are as follows:

• for a door leaf of 865-2050 mm, an opening of 900-2080 is used;
• for a web in 905-2070, it is necessary to use an opening at 940-2100;
• if the canvas has dimensions of 985-2070, then an opening of 1020-2100 mm is needed.

The size can be changed if the lining is made of natural wood with great thickness. Therefore, before buying, it is required to measure the existing opening, freed from the old structure.

Standard dimensions for doors in apartment buildings

In order for the front door to be chosen correctly and installed in accordance with all requirements, you need to know the following standards:

1. For new buildings today, the following dimensions are mainly used: height - from 1950 mm to 1980 mm, width - from 740 to 760 mm. It is important to pay attention to the series of the house, since the width of the opening largely depends on the size of the staircase.
2. Brick apartment buildings have larger openings, the width is 880-920 mm, and the height ranges from 2050 to 2100 mm.
3. The dimensions of the entrance doors of the old-style houses are different. More often these are single-leaf doors with a width of 830 mm to 960 mm, a height of 2040 mm to 2600 mm. Bivalve sizes are large, but it all depends on individual project at home, as there is no standard single value. It is impossible to reduce or increase openings without prior approval from certain authorities, as this can lead to various troubles.
4. The nine-story city houses that were built in the 70s have standard sizes close to the houses of the old series. The entrance can have dimensions of 1280*2550mm.

When choosing a door leaf, attention should be paid to the convenience and safety of the structure.

Staircases of apartment buildings do not differ large sizes, therefore, it is necessary to choose doors based on this. There are no such restrictions for private houses. When choosing, you need to pay attention to the convenience and its reliability, security from hacking.

The advantage of standards:

In the case of non-standard sizes of the doorway, doors can be made to order.

1. The widest selection. Basically, all manufacturers produce collections taking into account standard or close to them parameters. The choice of materials for finishing in this case is more extensive.
2. An individual order is an unplanned financial cost, and a standard order will always cost less. There will be an opportunity to spend funds on the selection of more exclusive decorative elements.
3. Ease of installation. The closer the dimensions are to standard, the easier it is to install. Additional works for decorating cracks, installing additional canvases is not required, and this is a significant time saving. Otherwise, installation will turn into a lengthy and annoying process.

What regulations apply?

The dimensions of the entrances may be different, but it is important to pay attention to the standards adopted today:

1. According to SNiP 210197 clause 6.9, all entrance doors belong to the group of emergency exits. They must provide free passage. The height of the canvas must be greater than 1.9 m, and the width may vary, but its minimum value depends on the purpose. For example, the width for residential premises may have a minimum value of 80 cm, but for office, commercial buildings it cannot be less than 120 cm.
2. Metal entrance openings that go to the landings, to the lobbies, should not have a width less than the flight of stairs. All data on this matter can be found in SNiP clause 6.29. This allows you to ensure the safety of the exit for those living in the house. This is especially important in emergency situations. We must not forget that too narrow entrances make it difficult to deliver to the house household appliances, massive pieces of furniture.

When choosing sizes doorways it is necessary to pay special attention to GOSTs, types of sheets, the presence of reinforcement or insulation of the sheet, design features. It is better to experiment with the selection finishing materials, exclusive decorative elements than with dimensions. The search for a suitable product can be delayed, and the result is not always impressive, so the standard is easier and more convenient.
