The dimensions of metal doors are the determining factors from which it is necessary to build upon when choosing and installing them. The quality and durability of the entrance structure depends on how accurately the standard for door production and the preparation of the opening for its installation is taken into account, taking into account all technical features.
Characteristics affecting the dimensions of the door:
- the material from which the door leaf with the box is made,
- type of door and its purpose,
- opening size
- manufacturer,
- weight.
What should be the doors in height and width
The standard to which the dimensions of the front door must meet is mandatory confirmed by the standards of GOST and SNiP and determined by the metric system. According to it, the size of the entrance opening for residential-type houses should be from 700 to 1540 mm in width, 2055-2060 mm in height and 75 mm in thickness.
The optimum width is 900-1000 mm.
According to these data, the size of the door leaf is selected:
- width from 600 to 900 mm,
- height 2 m.
Most of the paintings presented on the domestic market have standard dimensions of 800 or 900 mm excluding boxes. According to GOST, the parameters of the box must exceed the parameters of the door leaf by 6-7 cm, which means that the dimensions of the entire door block will be 870 or 970 mm in width and 2070 mm in height with an allowable deviation of 10-15 mm.
Also, when calculating the web in relation to the opening, it is necessary to take into account the technical clearance for mounting (10-20 mm) and the characteristics of the threshold height (25-45 mm).
Type of door construction
According to the type of design, the doors are distinguished:
- with transom,
- single leaf,
- one and a half
- bivalve.
Single-leaf are divided into standard and narrow. The width of the narrow can reach 600-650 mm. Their installation is permissible only in the case of an atypical layout of the building as an entrance group to a technical or storage room.
Other types of doors are non-standard and large-sized openings are mounted. Bicuspid entrance groups can consist of 2 canvases of the same size or have one wide and one narrow canvas (one and a half).
The width (mm) of one and a half is:
As a rule, in one-and-a-half constructions, the narrow part of the canvas remains dull and stationary, and in bivalve structures, both parts of the canvas can be movable. Their standard width in mm is:
The height in this case can vary between 2000-2300 mm. Non-standard constructions also include entrance groups with side and upper transoms, which are made to order.
Mass indicators: features that affect
It is also important to pay attention to the conformity of the dimensions of the canvas with the box. The slightest deviations in linear dimensions can lead to difficulties during operation or to a complete replacement of the input group. So, for example, using doors that are non-standard in height / width or purchasing them separately from the box, there is a risk that the weight of the metal door will deform the vertical support pillars of the box.
The result may be:
- difficulty opening / closing the web,
- door leaf warping,
- formation of crevices and drafts.
To avoid this, you must adhere to the following rules:
- it is necessary to purchase a door with a box from one manufacturer and in one set,
- the thickness of the canvas, as well as its height and width should correspond to the parameters of the box,
- fixing elements to the door and fasteners of the box to the opening should be used in a certain amount and selected taking into account the characteristics of the mass of the canvas.
Weight indicators depend on:
- steel thickness
- number of stiffeners:
- the presence of filler
- type of skin.
The optimal weight of a metal door is 70-80 kg with a box. Such characteristics as insufficient thickness and weight (less than 50 kg), as a rule, are found in Chinese manufacturers and indicate poor quality.
Doors weighing more than 100 kg belong to heavy-duty structures, however, they are also non-standard and, due to this, can cause problems during operation.
More detailed information regarding the selection of their dimensions can be found on the video.
What should be considered when calculating the dimensions of a door structure?
In the process of selecting a door entrance structure with a box, products should be purchased that have smaller dimensions than the opening itself. After measuring the width of the canvas, it will be enough to add an additional 70 mm to the obtained indicators. If we are talking about domestic manufacturers, the canvas in such products can have a width starting from 60 cm. The maximum dimensions can reach 90 cm.
In order not to make a mistake in size, it will be necessary to measure the entrance aperture as correctly and accurately as possible. In this case, you must take into account all the tips and recommendations above. Only a correctly selected front door can reliably protect the home not only from the penetration of intruders, but also from the vagaries of nature. With such a design, a warm and comfortable atmosphere will reign in any home.
Thickness is an Important Size of a Metal Door
Despite the fact that the thickness of the doors does not have a clear regulation according to GOST, this value remains a very important parameter. After all, it is from her that the stability of the iron doors to attempts to unwanted entry into the apartments, as well as the degree of protection of the premises from the fire, will depend.
You can easily familiarize yourself with the dimensions and thickness of a metal door on the Internet or in a specialized store
Single-layer steel structures should be no thinner than 2 mm. Welded metal sheets can have a thickness of up to 6 mm. Such doors are the most durable and massive, they can protect even a safe.
Each metal door consists of several sheets of steel. Between such canvases, stiffeners are installed, which make the structure stronger.
It is interesting that imported designs usually have a smaller thickness than domestic ones. Chinese doors, even with large dimensions, are made of fairly thin steel sheets. So, if the thickness of one sheet of the Russian door reaches 6 cm, then the canvas of the Chinese counterpart does not reach 4.
Standard door sizes
Standard dimensions are provided, the existence of which allows manufacturers to choose the overall dimensions of the entrance metal doors and simplify mass production. They are the most common parameters and are contained in state standards (GOST).
Height. A standard opening can be of various heights - from 207 to 237 cm. The specific figure varies depending on how high the ceiling is and how wide the door leaf is.
Width. The minimum width of the opening should be at least 91 cm. Bivalve structures can reach 200 cm.
Thickness. This parameter does not matter much, so the thickness can be any - doors that are not too wide are not made. However, this parameter affects the reliability of the door, its weight, sound and heat insulation qualities. To choose the right thickness of the door, it is necessary to proceed from the thickness of the walls and the box.
Useful Tips
Standard sizes may vary depending on the country of manufacture. In the CIS countries, the standard sizes are as described above, but in European countries the standards are different. It is quite possible that in the store entrance metal doors will be offered not in sizes familiar to the Russian consumer, but higher and wider. Dimensions can reach 240 cm in height and up to 945 mm in width.
Do not be afraid to purchase a box of non-standard width. It is unlikely that it will be possible to find a box with a width of more than 50 mm, and most often there will be products with a width of 20 to 30 mm.
When constructing a private house, it is better to design it in advance so that the openings are of standard size. This will allow you to put standard doors, which will save money on ordering doors of custom sizes, or to further reduce or increase the opening.
So, the door is easiest to choose based on standard sizes. The entrance metal door structure is preferable to other options because it better protects the house or apartment from thieves, it is moisture-, noise-, soundproof. The dimensions of such doors in the vast majority of cases are standard. Accuracy of measurements and the right choice in accordance with them is the key to success.
Custom Doors
The factories offer a wide range of interior doors with ducts and fittings, including non-standard options. But there are cases of inconsistency of manufactured products to the existing opening. In this case, you can adjust by increasing or reducing the height and width to the desired indicator. An alternative solution is to order custom designs with custom sizes.
The cost of manufacturing doors for an individual order will be higher in comparison with the purchase of finished products. But this will allow you to realize interesting ideas. For example, you can put the door of the compartment.
How to measure the opening
If the door has a door sill, the length of the opening can be calculated by summing the height of the threshold with the parameters of the panel, duct and mounting seam.
Fig. 7. Measurement of the width of the opening Fig. 8. Definition of indicators with and without a nut
When determining the dimensions, it is better to take into account the gap that will remain between the panel and the box
But this figure is 1-2 millimeters, so with approximate calculations it can be ignored
Varieties
Metal doors are very popular today, as they are durable and durable. Almost all modern owners of their own homes use similar products as input structures. Their use inside the living room is not relevant, since they have considerable weight and not such an original design that could be adapted to the specific style of a particular room.
Metal door leaves almost always come complete with a box, which eliminates its additional arrangement. These products are classified according to many characteristics. One such characteristic is the purpose of the canvas, which allows you to divide them into the following types:
- Input. These structures are intended for installation in places that directly contact the street. Such designs are durable and quality finishes. The metal is additionally treated with protective compounds to prevent its rapid corrosion. A subtype of such products are the front doors, which are installed directly on the entrances of multi-storey buildings.
- Housing. The name already speaks for itself. Doors are used as entrance directly to the apartment. Such constructions are additionally protected, since vestibule systems are externally installed.
- Office These canvases are a type of apartment door designs. But they are already distinguished by a somewhat increased level of security (they are equipped with thick metal, high-quality locks and the like).
- Technical These products are the simplest, as they are used only temporarily. They are installed as input in new buildings.
- Tambourine. Canvases of this type are also entrance, as they restrict access to the territory of several apartments. Products are distinguished by increased heat and sound insulation.
- Special The canvas of such a product is made according to certain requirements. Therefore, such designs can be protected from burglary, bulletproof, and also have high resistance to high temperatures (they can withstand open fire for a certain period of time). Each such door is checked according to various standards that regulate their minimum characteristics.
With regard to burglary resistance, the door leaves on this basis are divided into several types. First-class constructions correspond to Chinese doors that can be opened with a simple knife or with the application of physical effort. The most durable are modifications of the 4th class. These products are already supplemented not only with thick sheets of steel, but also with hidden hinges, high-quality fittings and so on.
Another parameter by which the doors can be classified is their design features.
Depending on this, the following models are distinguished:
Single leaf. Cloths of this type are equipped with a single leaf, which can open in one or two directions. This type of door is the most common. It is used almost everywhere, since such doors are compact and practical. The width of the structure together with the box can vary from 600 to 2000 mm
Please note that in this case the canvas itself will be slightly smaller, since the frame takes about 10-15 cm
All these types of doors can be supplemented with a transom, which is an independent partition above the frame.
Common parameters
GOST states that the parameters of the box must correspond to the dimensions of the canvas, taking into account the gaps required for installation of the structure. If the manufacturer created the model correctly, the indicators will be as follows:
The proportionality of the frame and the thickness of the wall opening must be observed. If you purchased a canvas of a smaller size - it does not matter, you can use such a device as an extension. He will close the gap tightly and hide the miscalculation.
The standard size of the door frame, which is prescribed in regulatory enactments, for a door to a room in height should be 190-200 cm. If the doorway is two meters, then the door itself is ordered a few centimeters less. If this is not taken into account, then she will not be able to freely close and open.
The standard web thickness is 4.5 cm. The width, as a rule, depends on the dimensions of the room itself.
Double doors have their own characteristics. Wide openings may be present at the entrance to any room, but most often they are found in living rooms. GOST reports that the width of these paintings should vary from 120 to 150 cm. These parameters contain functionality and ease of use.
The largest sizes of door frames used by manufacturers in Russia for interior doors are 90 cm wide. They are usually placed in industrial production, in offices or in large country houses. The opening should be proportional to the room itself. If the room is small, then the massive door leaf will look ridiculous or bulky. It is worth noting that in the Soviet "Stalin" this parameter was used, since the living area is very spacious. Such doors are produced in small quantities, and not very large enterprises make them exclusively on order.
Determining the size of the door and frame
The dimensions of the entrance metal doors can be determined independently, or you can turn to specialists who are involved in the installation for help. When measuring, you must be accurate. At the same time, it will be very difficult to determine the size required to install the metal door, if the old one stands still. Therefore, in this case, the help of professionals can not do.
Professional companies will advise on the optimal choice of a door that will meet the qualities and functionality for a particular room. They will make calculations that will determine the exact dimensions of the box of the metal door and the canvas itself. In addition, their help will not be superfluous in determining the optimal price.
Based on this, it will be easier for you to make a choice in favor of a finished design or custom-made door according to individual sizes. No one will understand the variety of manufactured products better than a specialist.
The correct selection of the entrance metal door
The entrance metal door, first of all, performs the main function - preventing unauthorized access to the room. Therefore, the classic front door must be reliable, but in addition to this, it must combine elegance and beauty.
The modern entrance door must be selected based on two important criteria - size and quality. In fact, even observing these rules, one may encounter many difficulties. After all, even the presence of GOST on the door leaf and the box can not guarantee you reliability. Since there are no general strict standards for all types of doors. Namely, metal entrance doors are not subject to mandatory certification, which can lead to the acquisition of poor-quality construction, and, as a result, the unreliability of the room and short service life. However, there are certain standards, although not all manufacturers rely on them.
But, for example, office doors, or for retail outlets and industrial premises, are very diverse, so there is no way to systematize them. Therefore, the standard, both in size and in GOST, is more relevant to doors installed in residential premises. And for other types of premises, sizes are determined individually.
Can I use custom size entrance doors
In many modern houses, especially if they were built according to individually developed projects, GOSTs are simply not taken into account. But it is highly not recommended to neglect the recommendations of SNiP, although in many cases they are bypassed and
So in a private house you can use any doors of non-standard sizes.
Of course, it is necessary to coordinate the dimensions of the entrance 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 among themselves, and all the necessary measurements can be made right at the construction site.
The size of a metal entrance door or a wooden structure can reach 900-2000 mm in width and 2000-2400 mm in height. It doesn’t make sense to expand the doorway anymore, except that it’s not about building a residential building, but about a public institution, for example, a small hotel, cafe or a very large house.
One and a half doors look very impressive and do not require large space
What else is worth paying attention to when choosing an entrance door: expert advice
In addition to all the main parameters that were considered, experts strongly recommend paying attention to some little things that later play a big role for the functionality and life of the door:
The first thing you should pay attention to is their number. The design with less than three loops is short-lived,
pay attention to the angle of opening the door - the maximum figure can be 90, 120 or 180 degrees,
the minimum permissible door leaf thickness is 40 mm, but at the same time such a door will not be fully protected
Therefore, it’s better to refuse such a purchase,
When choosing the front door, it is important to pay attention to the angle of its opening
metal sheet must not be less than 0.5 mm thick
The thinner the base, the shorter the life of the door,
it is important to pay attention to the presence of the armor plate, as it is considered a mandatory element and should be included in any case,
the thickness of the box should exceed the thickness of the door leaf by 2 times. This is necessary so that the fittings can be held and not cause damage to the structure,
it is better to give preference to models with ball loops and anti-cuts,
a one-piece profile is always preferable, as it is more reliable,
the presence of stiffeners is a prerequisite for those places of the canvas that are most vulnerable
So the strength of the structure will increase significantly.
These are the main aspects to consider when choosing a door. Among minor issues, a couple of other aspects can be noted: the presence of a manganese plate eliminates the risk of drilling a door
In addition, it is desirable that all fittings be produced by one company.
In the matter of the appearance of the front door, you can fully focus on your own preferences. The only thing you need to understand is that the dark door will retain its original appearance much longer.
The design of the front door should fit the interior of the hallway and be like a continuation of the house, part of it
As you can see, in the process of choosing the front door you need to take into account many parameters, the main of which are design features and dimensions. Iron doors must be well-fortified and equipped with reliable hardware
And, of course, it’s important that you like the front door visually, because you have to use it every day
What are the standard sizes of entrance plastic doors with a box in an apartment, cottage, private, country, country house according to GOST: width, height
Doors made of plastic are firmly entrenched in our lives. Today they are installed in stores, offices, shopping centers and other similar institutions. Plastic (PVC, polyvinyl chloride) is a well-known material from which not only door frames are made, but also windows. Today, many people have already been able to appreciate the strength and reliability of such structures, their simplicity in operation and maintenance.
During the manufacture of plastic doors, inserts made of metal are used. Therefore, such structures are also called metal-plastic. According to GOST, plastic doors have the following parameters:
- Height: from 2 m 17 cm to 2 m 42 cm.
- Width: from 70 cm to 91 cm.
By design, PVC doors are divided into the following categories:
- Single door. These doors can only open one way.
- Double doors. These doors, as a rule, open in both directions. They have a shtulp system of closing, thresholds, transoms on the side or top.
Standard for Plastic Entrance Doors
According to the type of filling, PVC doors are divided into the following types:
Deaf (insulation is located inside the door).
Glazed (in such doors there is a double-glazed window or a sheet of glass).
- Light (the lower part is made of canvas, the upper part is made of glass).
- Decorative.
Metal doors
Depending on the needs of the owner of the house, metal doors are placed single-wing, one-and-a-half or double-leaf. There are standards for the sizes of each of these types. Moreover, for each type, changes in height are possible when such doors are installed with a transom.
The following gradation of species is related to quality. The lineup includes the following models:
- "Standard" is a simple canvas, often imitating wood,
- "Elite" - increased thickness of the metal sheet and hidden loops,
- “VIP” - the thickness of the iron entrance door is even greater; there is an enhanced lock system.
Models are distinguished by the reliability and quality of the materials used.
What are the standard and minimum sizes of entrance doors in apartment buildings?
Thanks to standard doors, firms are given the opportunity to use special equipment that does not need additional reconfiguration for minimum dimensions.
Standard door leafs have the following advantages:
- On the market you can always find a large assortment of doors, which makes it possible to choose the most ideal model, taking into account your wishes and preferences. Firms make classic models of metal, insulated versions that are not afraid of temperature changes.
- Easy installation. Doors almost coincide with the size of the openings. They are fastened simply: the door is fixed with anchors. Non-standard elements are mounted more difficult. Here it is necessary to further expand the doorway.
- Price. Standard doors reduce significantly costs. And all because production algorithms are used that can be automated without problems. Many modifications are made from inexpensive materials. This also affects the cost of the product.
- Universality. After installation, the doors can be replaced without problems: the old canvas is dismantled, a new, standard size is inserted.
There are minimum and maximum parameters
To choose the right door for a new apartment, consider the following standards:
- If you purchased an apartment in a new building, then you will have to buy a door: 1 m 95 cm high - 1 m 98 cm wide, 74 cm wide - 76 cm.
- If your future apartment is in a brick apartment building, then the door will suit you: from 88 cm to 92 cm wide, from 2 m 5 cm to 2 m 10 cm high.
- In old apartments, designs are suitable: from 83 cm to 96 cm (width), from 2 m 4 cm to 2 m 60 cm (height).
Installation procedure
Before starting the installation, it is necessary to dismantle the remains of the old fasteners and completely clean the entrance arch from the plaster. When installing heavy steel inlet structures, the box is fixed in the inlet to steel bolts or fittings in pre-prepared holes. So it will be more difficult to crack, and it will be more stable during operation.
The next step will be sealing, which will require mounting foam. The box is bursting with wedges, bolts are tightened and then foam is poured between the frame and the entrance arch. After it dries, you can hang the canvas itself. If necessary, insulation can be laid on the outside of the input opening.
What are the standard sizes of entrance wooden doors with a box in an apartment, cottage, private, country, country house according to GOST: width, height
Similar designs have a variety of openings, with different sizes. These dimensions depend on a large number of indicators. So, if there is cladding or glazing, the door will have the following parameters:
- Width - 90 cm.
- Height - 2 m 10 cm.
The indicators that affect the parameters of the openings include:
- Dimension grid that is inside the frame.
- The number of flaps.
- The threshold value.
There are standards for the size of wooden doors
The thickness of the protective strips, which must be installed, may depend on the material:
- Plank of wood - up to 19 mm.
- Particleboard strip - up to 3 mm.
- Plastic strap - no more than 2 mm.
Dimensions of openings by type of building
Serial houses have always been built according to some standards, but the problem is that over time these standards have changed and now we have several types of doorways. Conventionally, the dimensions of the openings are usually tied to the types of buildings.
- Often in old pre-war houses, the width of the opening exceeds 1 m, and the height can reach 2.5 - 2.7 m,
- Post-war brick houses or as they are also called "Khrushchevs" were made with an opening width of 88 - 95 cm. The height here ranges from 2.05 - 2.1 m,
- In panel "brezhnevka" openings became narrow, on average they were 195x85 cm, with a tolerance in one direction or another up to 50 mm,
Door with box dimensions and options for openings
Examples and options
Nothing more - the usual standard metal entrance door with no frills. She looks strict and reliable.
A steel door with glass closed by a forged grating of a custom size is an example of style. To install it, it was required to increase the doorway.
Large door with a semicircular arch - the original box forced to enlarge the doorway and give it the necessary shape. But the entrance group turned out to be very attractive.
Another impressive door in the form of an arch, but this time amazing luxury. The combination of metal, glass and gold-painted carved forging and decor makes the product an excellent example of an artwork.
You will learn more about how to determine the size of entrance metal doors with a box from the following video.
In width
According to state standards, there are several parameters. Minimum specifications - 900,910 mm. The maximum size of a single-leaf web is 1010 mm. If we talk about one and a half designs, their width varies from 1310 to 1510 mm. Doors, consisting of two parts, have such parameters - 1910, 1950 mm.
By thickness
In terms of this parameter, there are no strict rules and regulations. The thickness directly depends on the overall design and the material used. The thickness should be optimal for the main task - to protect the premises from unauthorized entry.
The design of the doors can be double or single. Depending on the number of parts of the front door, the dimensions indicated in GOST will change. Single-leaf have a maximum permissible width of 1100 mm. The height of the entrance doors is 2300, the mass is 80 kg.
How to measure
There are a number of rules that should be considered when independently measuring the parameters of the input box and the canvas. Work can be provided to builders, however, you need to pay for it or take measurements yourself. You can take measurements with a tape measure of 3 meters.
- To take measurements, you need to get to the front of the wall with the front door installed. It is necessary to dismantle the platbands, if we are talking about the old model of the door.
- Sizing. It is not enough to measure the height near one slope or the width at the lower threshold and go to the store to purchase a box with a canvas. The width must be measured in three places - above, in the middle and from below. Height is measured near the right and left slopes. The thickness of the doorway must be measured in three places, as well as the width.
When all measurements are made, you can go to the door store. For an unmistakable choice, you must know the measurement system.
What is the entrance metal door with a box
We will find out what elements and details are included in the standard metal entrance door kit. So this is:
- The canvas itself.
- Wireframe.
- Framing,
- Special reinforcements that make the door more reliable construction.
- Sealant. It is necessary for heat, and for the door to fit snugly on the jamb: it closes and opens without problems.
- Platbands for doors are also part of a multicomponent design.
- Various additional accessories: peephole, door lock, handle.
- Door locks for metal doors.
But how to install an electronic lock on the front door with your own hands will help to understand this information.
As you can see, there are many elements of which the door consists. And it is necessary that they all function properly - only then the product will fully fulfill its role as the main "guard" of the home, and will not allow the owners of the house or apartment to freeze. But what kind of self-adhesive sealant for metal doors exists, and how to use it, this information will help to understand.
Recommendations
Please note that the size of the product is affected by the type of material from which it is made. For example, if the door is armored and thick, then the size for the same opening will be larger than that of a product from an ordinary profiled pipe. In addition, the size largely depends on the seal that is used in this product. For example, the sealant can be four- or six-ribbed, which gives additional rigidity, and, accordingly, the thickness of the structure.
You should also learn how to properly install the door.
Given the above, and other nuances, the approach to choosing an entrance door made of metal should be individual.If the owners of standard standard dwellings built during the Soviet Union can not really “bother” with the dimensions, since they have a standard doorway, those who bought housing in a new building will have to be careful in choosing: after all, modern housing is distinguished by an individual layout, unusual solutions, different heights of ceilings and openings. But is it possible to change the lock in a metal door, and how to do it right, is indicated here.
In addition, be sure to consider if a product is selected in a house or in an apartment building. If in a private house, then there may be much more options, since there is the opportunity to "fit" the doorway. But if the product is selected in a high-rise building, then the walls, especially the bearing ones, should not be touched, so you should select a door that is exactly suitable for the opening in size. It is also worth learning more about how it looks and how a magnetic seal for metal doors is used.
Standard door sizes: thickness, height, width
Previously, the entrance doors were sold separately from the boxes, and the buyer purchased separately the canvas itself, and separately - the platbands. And now it’s common practice to sell a ready-made unit with a box, which simplifies the task for both the seller and the buyer. And the standard sizes adopted in our country take this moment into account. We find out what sizes of doors are the most "running", and are recommended by state standards.
- So, if the opening height is from 207 to 210 cm, and the width is 88-96 cm, then the size of the metal entrance door with the box should be 205 cm high and 86 cm wide.
- If the width of the opening is the same, however, the height is 98-106 cm, then the product must already be acquired in the following dimensions: 205 cm in height and 98 cm in width.
- If the standard opening height is 270-210 cm and the atypical width is 90-98 cm, then the model is selected with the following parameters: 205 cm in height and 88 cm in width.
- If the opening is very wide (100-108 cm) at a standard height, then the size of the metal door should be 205 cm high and 98 - wide.
But how to choose a seal for metal doors, and what you should pay attention to, is outlined here.
Here are the dimensions of the entrance doors made of metal, which are considered standard. Please note that the dimensions are indicated with the box. The above parameters can be taken as a standard, and already starting from them, calculate the size for an individual layout.
Key Features
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.
For the manufacture of doors, two types of metals are used: aluminum or steel. The first is lighter, and the second is stronger. Also, when choosing a product, it is worth considering the purpose of the input system, its type, design features.
The door kit includes:
- Box. It is performed in the form of the letter P, supplementing with a threshold if necessary. Made from a metal corner. The thickness of the metal door frame is usually 80-90 mm.
- Sash. It is made in the form of a canvas, represents sheets of metal welded together.
- Stiffening rib. They protect the structure from distortion, twisting and other deformation. They can be transverse or longitudinal, often both types are combined.
- Interior and exterior finish (wood boards, MDF or plastic panels, paint, artificial leather).
- Insulation. It can be located inside the canvas or outside under the finishing material, for example, dermatin.
In addition, all accessories are supplied. It includes hinges, locks and other locking mechanisms (latches), eyes, closers, handles, rubber seals.
If necessary, mount a door in a country house, before buying it, you should think about arranging a visor. Better to order it right away. This simple device will protect the canvas from precipitation and direct sunlight, thereby reducing burnout.
How to make measurements yourself?
To select a metal door in a store or order it on the Internet, you should, first of all, calculate the dimensions of the entrance metal doors with a box. We need to approach this issue very responsibly. If there is a plan for an apartment, then the dimensions of all the openings on it are indicated. However, it is better to double-check them with your own hands in reality. Indeed, over time, any design shrinks.
The process of sizing an iron door with a box:
- First you need to take a ruler or tape measure. It’s easier, more convenient to work with roulette, it allows you to measure large values, especially with regard to the height of the opening.
- The old door must be removed, be sure to remove the threshold. It will not be superfluous to check the curvature of the opening using a level. If the skew is significant, then first you need to align it. Otherwise, the new product will not function normally, will become frayed, and the locks will not close properly.
- To get the width of the door you need to measure the distance between the verticals. All parameters are recorded in millimeters. Measurements need to be done several times in height, preferably 3-4 times, select the minimum value. It is important to remember that the width of the opening is not the width of the sash, because the box is also installed in the aisle. It is between its verticals that it is necessary to make measurements.
- In the same way, measurements are taken 3-4 times between the upper and lower levels. Record the smallest height value.
- Measurements must be accurate. After all, if the product is smaller than the opening, then you have to think about how to fill it. When the canvas is larger, you will have to expand the passage. Anyway, 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. The standard sizes of iron entrance doors are usually 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 characteristic for country houses, non-residential premises. Their manufacture will cost more than typical products.
Also, when taking measurements, it is necessary to consider in which direction the sash will open. If it is outside, then in an 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 convenience of using the design.
Single and double models
The height of the structures can vary from 2 meters to 2.3 m. In some cases, transoms are arranged in the upper part of the opening. This is typical for a private house, where the dimensions of the opening for the entrance iron doors are too large. They do not have to be rectangular. The arched form with stained-glass glazing looks beautiful in a country house.
As for the width, it is different for different types:
- Single-leaf structures are equipped with one canvas. It can be narrow in 600 mm or 650 mm wide. Such models are mounted in typical rooms, technical, warehouse. More common are standard canvases.
- Bivalves can have both workers full or only one, they are also called one and a half. They have one part, narrower, which is closed 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 a working canvas of 800 mm or 900 mm.
- Double doors have both canvases of 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 breaking. Sometimes it is increased to 3 mm. Thicker metal is not used, so as not to significantly increase the weight of the door. Exception - bulletproof products, fireproof, they require reinforced loops that can withstand the appropriate weight.
The thickness of the web in the manufacture of conventional, standard insulated cloths is from 60 mm to 80 mm. If the products are reinforced class, then this indicator will start from 80 mm and reach up to 100 mm.
This parameter is affected by:
- Sealant, its dimensions. This is a rubber contour that 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.
- Insulation. Through the door from the room leaves up to 25% of the heat. 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
The EU countries have their own standards for the size of entrance metal doors, referred to as DIN. For the manufacture of metal doors, fairly light steel is often used.
In different countries, the concept of "standard size" may differ:
- Products from Spain are produced in a width of 600-1000 mm.
- Canvases from France have a different width: 690-990 mm.
Therefore, when installing imported products in a domestic opening, you will have to significantly alter it (increase or decrease), depending on the size of the steel doors with a box. Also, different brands have completely different warranty periods for products, it is worth paying attention to when buying a product.
To avoid the hassle of installing a metal door, you need to correctly calculate the dimensions of the metal door with the box: height, width, depth. If you plan to order goods with installation, it is easier to entrust this business to the measurer. With an independent purchase and installation, you can do all the measurements yourself with the help of a tape measure.
Door Measurement Systems
There are two systems for measuring door structures - metric and English
It is important to know their differences, so as not to get confused when choosing
When measuring and choosing a door, it is recommended to listen to the advice of builders:
- The sheet of steel used in the manufacture of the entrance door leaf should not be less than 2 mm. With insufficient thickness, the material will not be able to perform its functions.
- Choose the opening mechanism in the apartments so that when you open the door outward, it does not interfere with the neighbors.
- Take into account the weight of the structure. With non-standard dimensions, it is necessary to additionally strengthen the bearing wall and ceiling.
- For reliability, it is better to use wooden or metal cloths. Durable material will allow you to achieve maximum levels of protection of the room and durability.
- Wooden doors should be equipped with platbands. With a large width of the walls, doborniki are used.
- In cold climatic zones, you need to choose structures with high thermal insulation.
- It makes no sense to install a double-wing structure in an apartment or a small private house. They are used in shopping centers, cinemas, catering establishments, and hotels.
- To install the front door does not need to purchase specialized equipment. The work is carried out using a hammer drill and anchor bolts.
It is important not to forget about the design. The front door should be in harmony with the interior and meet the tasks assigned to it.
Metric
This is a measurement system familiar to the population of the CIS countries. It uses kilograms, meters, centimeters and millimeters. There are two standard indicators used for entrance doors of different materials. The size of the wooden structure: 2040 mm - height, 826 mm - the width of the front door. Metal size: 2050 mm - height, 860 mm - width. These are standard dimensions.
English
This is a foreign measurement system that is used in Western countries. The unit of measure in it is foot. It is 30.48 cm. In addition to being used in Western countries, branded models can be measured in feet.
If you have a desire to purchase an expensive door construction from foreign manufacturers, you need to understand the companies and know the foreign designations of quantities.
For error-free acquisition of the front door, you need to conduct independent measurements, pre-select the material, opening mechanism and design. If you have doubts about your capabilities and skills, you can call people involved in the installation of entrance and interior doors.
Models of metal doors
Almost all modern manufacturers produce metal doors according to the same standard standards. Let's talk a little about these standard models so that you have an idea about them.
- Standard Model. This is an economy-class door whose top cover imitates wood.
Model "Elite". This is a metal entrance door that is already insulated. In addition, the dimensions of this model can be selected individually. The hinges are hidden from view, and the outer casing is made of thick durable metal. But how you can use gaskets for interior doors in the groove, and how to choose the right one, is indicated here.
Platinum Model. This is one of the expensive models. It uses compacted durable material, and the locks are equipped with additional protection. But what are the aluminum profile locks for sliding doors, you can see here.
VIP model. This is also a product made of especially durable metal. Sizes are selected individually. Additional crossbars provide reliable protection of the home from intruders.
Models such as Stained Glass or Grandstyle decorated with decorative glazing. These models are more suitable for private homes.
Model "Arch" made with a rounded top, ideal for arched doorways.
In addition to those listed, manufacturers offer other interesting models of entrance metal doors. A variety of finishes, materials, degrees of protection and other characteristics allow the buyer to choose a product with any request. In such a door most often there are rather thick glasses, but if you still have to change it, it is best to familiarize yourself with the information on what to insert instead of glass in the interior door.
Dimensions of metal doors with a box
The dimensions of the metal doors are slightly different from the above standards. The fact is that such structures are stronger and heavier than wooden or plastic paintings, and therefore have completely different dimensions.
Particular attention should be paid to doorway measurements if you intend to install a metal door
Regardless of the width of the doorway, you can put such doors. They have several options for standard dimensions.
There are only two standard heights of metal doors, and their width can be completely different. So door structures with a height of 200 cm can have a width of 60, 70, 80, 90 or 120.2 cm. If the vertical size of the product is 230 cm, then its width will be 90, 140.2 or 180.2 cm.
Metal doors are superior to wood and plastic products in fire safety, strength and resistance to burglary. Therefore, they are the most sought after products in the construction markets.
How to choose the size of the metal entrance door with a box
When choosing a door to your apartment, you must be guided by the principle: "Measure seven times - cut once", since the front door is very difficult to fit under the doorway. As a rule, in modern times, metal devices are installed at the entrance to the apartment. Back in Soviet times, such products were exclusively at the entrances to the basement warehouses, and for apartments they chose ordinary chipboard products with a filler. However, now you will find such doors only in new buildings, and then as a "makeshift."
Until recently, certain dimensions were not respected in the manufacture of metal entrance doors. In this regard, many apartment owners have encountered the difficulty that the size of the entrance metal structure is much larger than the size of the entrance box. This made installation very difficult, it was necessary to expand the opening, and this took extra effort and time.
Dimensions according to GOST
Now there are fewer such cases, as a rule, this happens if you order a poor-quality door with a Chinese-made box. A GOST 24698-81 determined the standard sizes according to which there is an arrangement of an entrance doorway in houses under construction.
Here are the dimensions of the entrance door frame in accordance with GOST in millimeters:
- Height: 2071, Width: 671,
- Height: 2071, Width: 770,
- Height: 2071, Width: 870,
- Height: 2071, Width: 970,
- Height: 2071, Width: 1272,
- Height: 2371, Width: 970,
- Height: 2371, Width: 1472,
- Height: 2371, width: 1872.
And this dimensions of the entrance metal door (canvas) according to GOST in millimeters:
- Height: 2000, Width: 600,
- Height: 2000, Width: 700,
- Height: 2000, Width: 800,
- Height: 2000, Width: 900,
- Height: 2000, Width: 1202,
- Height: 2300, Width: 900,
- Height: 2300, Width: 1402,
- Height: 2300, width: 1802.
The dimensions of the canvas and the boxes correspond to each other according to the number in the columns.
Manufacturers comply with these sizes.. Such processes are carried out both by domestic and the bulk of European companies. However, Chinese-made metal entrance doors have a much larger range of sizes.
Quality standards
Each metal door will find its consumer. The fact is that today this market is well developed. Domestic and foreign manufacturers make metal sheets, given:
- safety standards
- strength,
- fire resistance
- level of security against hacking.
Based on the foregoing, these are the criteria that are followed by most bona fide manufacturers. Web thickness should be not less than two millimeters. if one metal sheet is used, and not more than six millimeters, if the sheets of the structure are spot welded together.
In order for the web to be rigid, V or U-shaped “stiffening ribs” can be placed between the metal sheets. Standard metal products consist of two sheets of steel sheet.
Typically, domestic products have a large thickness of metal sheets. Imported products, on the contrary, are thinner. So, for example, Chinese metal products, regardless of size, can not boast of a sheet thickness of more than three or four millimeters. However, if the canvas is made to order, then, in both cases, the thickness may be different.
Custom-made products may have more metal sheets in the canvas. On the basis of this, such canvases can have an individual thickness, size and decorative design. But the safety standards and overall parameters established GOST R 51072–97, GOST 31173–2003 and GOST 6629–88 must be respected.
Standard and custom sizes
Metal products and openings are:
- standard
- non-standard
- bivalve
- semi-soluble.
Most commonly applied aperture size 800x2000 mm. That is, the box has dimensions of 2017x870 millimeters. Such dimensions of doorways can be found more often than others.
However, when purchasing new metal products, it is necessary to take into account the factor that the entrance openings may vary in size in the houses of the old and new layouts. So, for the old layout, it may be necessary to manufacture a non-standard canvas.
But often, in the doorways of old houses there is a frame from a wooden frame, which allows you to expand the entrance and install metal products of available sizes. In new buildings, the doorway cannot be expanded in this way, because, as a rule, the edging there is steel.
Regarding double-leaf products, it is possible to install it with the smallest width of the door frame 1272 mm, but it is recommended to use the width not less than 1472 millimeters. For the installation of semi-leaf paintings it is necessary to be guided by dimensions of 970 millimeters.
Non-standard, as well as double and half-leaf metal doors, are usually ordered for installation in cottages and private country houses.
The variety of models of metal products
Standard canvases differ from each other not only in height and width, but also in model. Here are some basic models:
- “Standard” is a basic model of an economy class that imitates valuable species of wood. Such a door is covered with vandal-resistant decorative material and has a complete set of necessary fittings and accessories,
- "Elite" is a modern model, which is distinguished by hidden hinges, a reinforced lock case and a crossbar system,
- Platinum - belong to the classic elite models of entrance metal doors. Has a reinforced protective protector of the protective mechanism,
- VIP - a modern door that is equipped with a reinforced deadbolt system and an Interactive cylinder,
- “Metallic”, “Quadro”, “Stained-glass window”, “Grandstyle” - all these models are glazed metal entrance doors. but different in design,
- "Arch" - represents a standard door of arched type.
Standard Entrance Door Sizes
To replace an old product or install a new one, it is necessary to carefully familiarize yourself with the different sizes of the entrance doors. As a rule, there are parameters determined by GOST, but if there is a need, today you can make an order for a door according to your individual requirements. Although this option may not be suitable for all models.
Basic requirements for entrance doors
Designs can have various indicators of reliability, which are dependent on design features, well, as well as on the material used and the integrity of the manufacturer. If at least one of these components is not available, then this affects the entire structure, or more precisely, its reliability.
The essential components of each product for this purpose are:
- reliable fortifications
- sealant material
- door frame
- door leaf and frame,
- high-quality fittings (hinges, locks, handles, etc.),
- platbands.
As a rule, the dimensions of the metal entrance doors also depend on the material used. For example, for complex armored doors, a very thick metal corner is usually taken as the basis, the thickness of which is at least 50 or 60 mm. In other cases, they can also use a special profile pipe. The manufacture of such a frame often takes from one to two sheets of high quality steel. The ribs are located on the inside, they give rigidity to the structure. They are usually from four to six. And it will be better if the ribs are located in addition to vertical in the horizontal direction.
The cavity of the entire structure must be filled with insulating and sound-absorbing material over the entire area of the door. The final door size also depends on the types of fillers.
How to choose the front door?
It is important to remember that today there are a lot of standards for dimensions and you need to act individually for each individual case. Also, do not forget that the houses have completely different sizes due to the rapid development of the latest technologies. Therefore, it is not so easy to choose the right product.
It can be concluded that the question of what are the standard sizes of entrance doors today is already a thing of the past. Standards need to be followed usually only in interior options.
When installing doors, you need to focus on where this structure will be mounted, for example, in a house or in an apartment. In the first embodiment, the choice is much easier to make, which is caused by the load on the wall, which is much less than in apartment buildings.
Measurement system
The standard size is 91 centimeters for opening the front door. Based on these data and taking into account the thickness of the associated gaps and the thickness of the box, certain door parameters can be distinguished.
- When establishing a standard canvas with one leaf, the size will be 204 by 82.5 cm.
- For metal products 205 by 86 96 cm.
- And if desired, it is possible to put a canvas with two wings, however, given that the width will be approximately 200-205 by 160 cm.
Immediately you need to prepare for the fact that the initial lunette may not correspond to these numbers, because current builders do not particularly adhere to the rules and norms. Because of this, most likely, if the house was not built by you yourself, you will need to seek the help of trained specialists who are able to custom-make the product. For residents of the private sector, there is the opportunity to make a remake of the lumen.
There is an opportunity to try to solve this problem with the help of additional tools that are used specifically for these purposes. To avoid a headache, before leaving for the store, you must accurately take measurements from the opening.
How to measure the front door?
In order not to make a mistake when purchasing a door structure, it is necessary to accurately and correctly measure the width and height of the opening.
This procedure is done as follows:
- Measurements need only from the plane of the walls. For this, it is first and foremost necessary to remove platbands around the entire perimeter, they also occupy a certain area.
- Next, you need to use a centimeter to calculate the indicator for width and height. In that case, the code numbers do not meet the standards, you have to work on the clearance, narrowing or expanding it.
- It is also worth considering unforeseen circumstances. If, for example, the building is quite old, then the walls may crumble or the plaster will fall. To do this, you must first clean the passage.
Calculations depend on the evenness of the surface, so you need to pay special attention to the surface. The best option is to always carry a plumb line or a building level. because it is these tools that can do a flatness check.
Standard dimensions
When you already have all the dimensions of the doorway on your hands, you can roughly orient yourself in a suitable design format.
Often the ratio of these parameters is as follows:
- If the width of the doorway is 88-96 cm, and the height is 207-210 cm, the block size will be 205 by 86 cm,
- If the lunette has a value of 207-210 by 98-106, a suitable block would be 205 by 96 cm,
- If the baseline is 207-210 at 90-98, you need a block at 205-88 cm,
- When the doorway has the following parameters 207-120 by 100-108 cm, it is worth choosing a product with dimensions 205 by 98 cm.
These values are considered standard, which is why these data can be safely repelled when acquiring a system.
We take into account the door frame
It is worth considering the dimensions of the door with the box, in the sense of the entire installation structure, as a whole, making calculations. Why is this so important? Once the doors were sold on their own, that is, there was only a door leaf on sale. But today, thanks to the development of technology and design designs, the box is now an integral part of the entire kit.
This moment is of great importance for homeowners, because they have a wide selection of products. For example, it is possible to install the so-called double complex at the entrance, this will create some kind of vestibule, where there will be a separation between the house and the street. At the same time, it is protected by doors on both sides.
This method will make it possible to create a separate room where there will be a change of street clothes to home, as well as such a vestibule will provide additional protection against cold and noise from the street. This design fits easily with the standards, so there is no need for special passage sizes.
If the owner cannot determine exactly what he wants, for example, to order an arched door or a double-wing model, then it is not particularly necessary to measure the opening. For the most part, houses have a lunette of this size: height 207 and 237 cm, and width 87, 97, 127 cm. And if you need to install double doors, the width should be equal to 187 cm.
What material to choose?
1. When discussing the choice of materials from which the front door will be made, it is worth considering that at the moment it is metal that is considered the most popular material, because it is difficult to compete with its strength. However, with additional protection (fencing in private houses) or additional doors (in apartments), it is possible to pay attention to other options as well.
2. The door structure may be made of tempered glass, PVZ and many other similar materials. The main convenience is that the dimensions of the plastic entrance doors can be ordered separately, just for your needs. At the same time, the price of such a product will be cheaper at times metal.
3. If you purchase a ready-made PVC door, it is worth noting that finishing work on the doorway will need much less, because the installation of such a model is much easier, unlike other "serious" doors. Also, if you wish, you can make a choice in favor of products that will be made of various materials, which is very convenient when creating a harmonious picture of the interior of the room.
When choosing plastic doors, it is important to note that when installing such a product, one must not forget about the additional elements that are necessary in the inevitable order, in order for the products to perform a protective function one hundred percent.
Extras to Remember:
- Metal inserts in the form of plates having a closed section. They are needed to increase the strength of the profile of the box and sashes,
- Additional locking mechanisms interacting with folds and shutter mechanisms,
- Crossbars in the design of locking mechanisms. They are installed in the door leaf (such as metal products),
- Elements of the anti-vandal system must be present. These are such as shultzi, gate valves and other similar parts,
- If a plastic door is mounted in an office building, installing an electric door closer will not be superfluous.
In no case should you neglect your safety when installing plastic doors. Additional protection will always be necessary.
Summarize
In conclusion, I want to say about the manufacturers of door systems. If you make a choice of doors of our domestic manufacturing plants, their products are manufactured in accordance with GOST 6629-88 and SNiPa. All standards were developed, focusing on the physical dimensions of an ordinary layman. As for the import options, then the top they correspond to our domestic doors, and as for the width, they can vary significantly. Because of this, this point must be considered when acquiring a door structure.
Domestic products are made taking into account the walls of 750 millimeters. If for some reason this parameter does not correspond, then it can be corrected with the help of developed schemes, such as, for example, additional rail.
In general, the main dimensions that you need to navigate are the width and height of the doorway itself. But the thickness can be fixed at any time.
Standard sizes of entrance metal doors with a box
Choosing the front door is the first step in protecting every home. And no one should take this question lightly. Convenience and time during which the door will perform its functions depend on a responsible and serious decision. There are many standards that define doorway parameters.
If everything is clear with the buildings of the last century, then new multi-story or private houses are being built according to different plans and technologies.Therefore, to accurately understand the standards of entrance doors with a box is not an easy task. And in a private house it is much easier to mount a door (you can adjust the opening without damage to all floors) than in a high-rise apartment - the load on the walls is much higher, as a result of which the building is in danger.
- Doorway Dimensions
The panel house provides for the dimensions of the door leaf, according to GOST:
- Width in the range of 740-760 mm,
- In height within 1950-1980 mm.
In a house that is built of brick, the following are considered valid values:
- Width within 880-930 mm,
- Height within 2050-2100 mm.
The same type buildings of the last century had doorways:
- Width - 830 - 960 mm,
- Height - 2040 - 2600 mm (over 2200 mm - non-standard parameters).
To make a qualitative measurement of the doorway for those dimensions that deviate from the standards, it is necessary to dismantle the old door frame. And the place where she previously stood was to clean up the remains of debris: old mounting foam, plaster, paint and putty. This is desirable to do immediately, because when installing a new door, cleaning excess material reduces the speed and ease of installation. You also need to check the level (horizontal and vertical), measure the distance along the entire perimeter of the opening - between the sides of the wall, as well as the bottom and top of the opening.
Height, width, thickness - these are indicators of the dimensions of the metal door, which should have a strictly rectangular shape. According to GOST, a deviation of up to 3 mm is permissible.
- Standard sizes of metal doors
The most common sizes of metal doors and openings for them are regulated by SNiP and GOST standards. In the event that the opening does not meet the requirements of these rules and standards, it must be brought to the required standards BEFORE installation begins. All products coming into mass production are marked with which it is easy to determine which type the door belongs to.
Below are their main parameters:
1 - marking according to SNIP,
2 - parameters of the metal door leaf, mm,
4 - Dimensions of the opening, height / width, mm.
(1) 21-7, (2) 2000x600, (3) 2050x668, (4) 2050-2100 / 670-720,
(1) 21-8, (2) 2000x700, (3) 2050x768, (4) 2050-2100 / 770-820,
(1) 21-9, (2) 2000x800, (3) 2050x868, (4) 2050-2100 / 870-920,
(1) 21-10, (2) 2000x900, (3) 2050x968, (4) 2050-2100 / 970-1020.
- Metal products of custom sizes.
Many houses are built according to individual projects, so there was a need to develop non-standard types of doors, but they also have their own standard parameters, which were thought out by masters for greater ease of use.
Non-standard products have already got their name - “high entrance doors”. If you intend to ennoble the appearance of your home, you need to approach it carefully and seriously.
To choose a non-standard door, it is worth knowing some data that will help to make a choice:
- For products whose height is 2500 mm, a width in the range of 600-1000 mm is characteristic. The step pitch is 50 mm in height and 20 mm in width. The standard and optimal door leaf parameter is 900 x 2500 (width X height, mm).
- In an opening measuring 1040 x 2550, it is more appropriate to install doors of 940 x 2500 mm. In this case, the landlord will receive unhindered entry into the room (910 x 2470 mm, with an installation frame). Such a passage will help to bring any household appliances and large furniture into the house without unnecessary efforts.
If you still have doubts, then a non-standard entrance door of 940 x 2500 mm is the best option when installing in a building.
- Door leaf thickness
Not only the general parameters of the product are important for the characterization of operational properties - not the least role is played by such indicators as the thickness of the door leaf and metal sheets. The first parameter is not fixed and may vary.
- 60-80 mm - a standard indicator of a door installed at the entrance to an apartment or private house,
- 80-100 mm - a standard reinforced design that combines thermal protection and burglar-resistant properties.
All iron entrance doors are made taking into account durability, heat resistance, and, accordingly, safety. According to the standards, the total thickness of the door metal sheet varies between 2-6 mm. Between the sheets of steel are placed "stiffeners", which allow the structure to maintain its appearance, not to deform over time and prevent breaking.
The total weight of the door structure must not exceed a limit of 250 kg. But, know that if the door is heavier than 200 kg, then according to GOST standards, fixing on three hinges, instead of two, is required. The same rule applies to the installation of the product, regardless of weight - in public places. According to the requirements of GOST, the middle (additional) loop should be fixed 15-20 cm. Below the top. Installation of the entire structure is carried out on special mounting ears, which are attached to the frame by welding. Such ears come with a door.
How to measure
Before placing an order on the corresponding website or going to the store, you must carefully take measurements from your own doorway so that the selected product matches the declared parameters as closely as possible. A few recommendations for taking measurements.
Make all necessary measurements from the wall. If old platbands impede this, remove them. In addition, it is necessary to clean the base of the door from crumbling plaster so that the dimensions as accurately as possible reflect the real parameters of the opening.
You can take measurements with a tape measure or sewing centimeter. After you have measured the height of the opening and its width, check the standard sizes indicated above, and if your parameters are different, measure them again. If the secondary control measurement showed the same results, then the product will have to be purchased non-standard.
How to insulate yourself
When purchasing an entrance door made of metal, you need to think about its protection from the cold, especially if the product does not provide any "built-in" insulation. The realities of our country do not allow us to do just a door leaf, and this is especially true for owners of private houses. We find out what points need to be considered when choosing material for insulation, and performing the work itself.
Keep in mind that the metal the door is made of is an excellent heat conductor, so the outside, street side of the door will have almost the same temperature as the inside, home. Due to the temperature difference on the outside, condensation is likely to form, which negatively affects the metal elements, accessories, and the canvas itself. This happens when the door is not insulated. In addition, the lack of proper insulation of the entrance metal door leads to the fact that wind and cold penetrate into the gap between the canvas and the frame, which worsens the microclimate of the home. For those who want to learn more about how the insulation of an iron door occurs, it is worth following the link.
Fibrous
Mineral and stone wool, which can be made of hard plates, or can be soft rolled, are classified in this category. The advantages of these materials include their remarkable heat-insulating ability, incombustibility, and excellent noise-insulating qualities. At the same time, their installation will be very simple, accessible even to a person who is far from any construction work.
But fibrous materials have their own minus - this is their fear of getting wet. If condensation builds up on such a heater, this can lead to a loss of cotton volume and subsidence over time. Due to this subsidence, the upper part of the door may be unprotected. In connection with this significant minus, cotton wool is not used to warm the entrance doors of private houses. However, it can be applied if the door leads to the apartment building.
Styrofoam
Polystyrene can also be included in this category, in which the bubbles are filled not with air, as in polystyrene, but with nitrogen. These materials are solid in shape, available in slabs, cut well, and are easy to install.
Moreover, the thickness of the plates can be different, which makes it possible to choose the optimal one for a particular case. These materials are not afraid of moisture, therefore, they are quite suitable for entrance doors in private homes.

This video will tell you how to measure the doorway yourself:
We examined the features of sizing and insulation of entrance metal doors. Now, with a minimum set of tools and the necessary parts, you can easily make your house warmer, and also knowingly choose what should be the metal and aluminum front door of the right size.
We also bring to your attention an article about entrance wooden doors.
Degree of protection
The specific purpose of the entrance group is also a determining factor when choosing the size or arrangement of the opening. This is how standard and technical doors differ: fireproof, armored, sound- or moisture-proof. The characteristics of special constructions significantly increase the degree of housing protection.
For example, the thickness of the fire door is 7 cm, and the armored door reaches 10-12 cm. The dimensions of fire-resistant structures are more impressive and can reach about 2500x2500 mm, which is due to the requirements for passability during evacuation. Armored can also have non-standard dimensions (1200x1900 mm), however more often they are produced with dimensions of 1200X2050 mm.
When choosing the optimal entrance structure, it is very important to consider how much a metal door weighs, its thickness and other overall characteristics. It depends on whether it will correspond to the opening and whether it will be able to protect the house from break-ins, cold and drafts.
