It will not be possible to turn a house into an impregnable fortress without a reliable, strong and durable front door. Metal doors are considered ideal in almost all respects; they are significantly superior to their wooden counterparts in terms of protection and safety. However, the door is different - the modern market is so oversaturated various options , that you can find both flawless and one that can be easily cracked even by an inexperienced burglar. How to choose metal front door so that she provides, pleases with appearance and impeccable service? Let's dwell on the most important points that everyone should know before going to a store or specialized company.

Attention! As you read our material, you will understand that when choosing an entrance door there are a lot of nuances and they are all important. In turn, manufacturers are forced to sacrifice some parameters in order to make their product competitive in price for the mass consumer. In the case when you are not ready to compromise and are ready to pay for a quality door according to your needs optimal characteristics, then it is better to make a door to order directly from the manufacturer, where all future nuances can be discussed and written down in the contract.

No. 1. Design features of a metal door

The strength and reliability of a door depends to one degree or another on the characteristics of each of its constituent elements:

• door leaf - the main and largest part of the structure, consists of a frame, internal and outer skin, as well as stiffeners and;
• door frame;
• lock;
• loops;
• seal in one or more circuits;
• , and other accessories.

Door leaf made of sheet steel, which is obtained as a result of hot or cold rolling, on which the properties of the door largely depend:

• hot rolled steel It has a dark color, but it is not visible under the decorative coating. This is a relatively cheap material that is more susceptible to corrosion;
• cold rolled steel will cost more, but in terms of performance it is best option– the material is not afraid of any weather influences.

The strength is also greatly influenced by the frame. The most reliable door will be the one in which the frame is made from a profile pipe with one seam. A less durable frame is made from four sections of hot-rolled profile pipe, interconnected. The most unreliable will be a frame in which each of the four segments is welded from two corners of equal length. Simply put, the fewer welds in the frame, the better, because each of them reduces resistance to mechanical loads. The outer part of the door leaf should be made only of monolithic non-welded sheet, otherwise a blow with a medium-force sledgehammer will damage the integrity of the structure.

No. 2. Steel thickness

The most important aspect that needs to be clarified when choosing a door is the thickness of the steel sheet. This parameter may vary from 0.8 to 5.0 mm: the higher it is, the more reliable and durable the door will be. Along with the increase in safety, the price and weight increase, which is also important to take into account.

Scope of use of doors with different thicknesses steel sheet is significantly different:

Some manufacturers use steel sheet only on the outside, insisting that this is enough to create a durable structure and making the internal panel, for example, from MDF. To be completely sure of own safety, it is better to choose a door with two steel sheets. On sale you can find options that reinforced with another additional sheet of steel, located between the main external and internal ones, is the ideal of strength. Such doors cost much more than their simpler counterparts, weigh more and will not be useful in all cases.

When choosing a metal door, it is recommended to pay special attention to castle zone, since when hacked it often takes most of the load. It’s great if this place is covered with a reinforcing sheet of steel or even - this is a huge plus in terms of reliability, even if the door is made of not very thick sheets of steel.

No. 3. Number of stiffeners

Between the outer steel sheet and the inner panel, no matter what it is made of, there must be stiffening ribs that are necessary to achieve maximum strength and resistance to mechanical stress. Stiffening ribs can be located vertically, horizontally or diagonally: it is important that they are located evenly throughout the entire structure, which is why it depends.

The minimum set of stiffeners is two vertical and one horizontal. It is better if there are more of them, but without going overboard, because they significantly increase the weight of the entire structure.

Stiffeners can be produced:

No. 4. Thermal insulation and sound insulation of a metal door

Metal is not the best insulator from cold and extraneous sounds, so earlier, when metal doors had just begun to appear en masse in Russia, it was common practice to install two at once: one metal to protect against unauthorized access, the second wooden to retain heat in the apartment . Today the situation has changed significantly: although a metal door has cold bridges (this is a frame and stiffeners), it can become an independent protection against drafts, odors and cold.

High heat and sound insulation characteristics are achieved through the following elements:

Thermal insulation material is inserted between the frame and the stiffeners, filling the entire space between the outer and inner sheets. More often In the production of steel doors the following insulation materials are used:

• mineral wool- the most common option. The material has excellent soundproofing and noise-absorbing properties, retains heat, does not burn or emit harmful substances, however, it is prone to subsidence, so it may require additional sheathing;
  
• has excellent heat and sound insulation properties, is durable, resistant to changes in temperature and humidity, but is easily flammable and costs more than mineral wool;
• – one of the cheapest options. The material retains sounds and heat well, but is easily flammable, and the gaps between the foam and the stiffeners will need to be filled;
  
• penoplex in many ways resembles mineral wool, but is slightly inferior to it in fire resistance;
• foam rubber and synthetic winterizer are used infrequently, since to achieve more or less acceptable insulating qualities a layer of 10 cm is required;
• paper and pressed cardboard- good insulators, characterized by low cost and light weight, but inferior in moisture resistance to other materials.

It is important that the manufacturer also fills the internal cavities of the metal profiles with insulation, otherwise we can talk about high thermal insulation qualities no need to. It is not difficult to check this - just tap the surface with a metal object: a dull sound indicates that the insulation is of high quality.

No. 5. External and internal finishing of a metal door

The steel sheets of the door leaf need decoration. When choosing interior finishing It’s worth starting only from personal preferences and the nuances of arrangement. Exterior finishing must be resistant to changes in humidity, precipitation and sunlight if the door leads to the street, and withstand mechanical stress if you have pets. In the case where the door leads to a vestibule or entrance, there are no special requirements for its external decor.

The most popular finishing options:

• powder coating involves applying special paints to the surface, which, under the influence high temperature form an anti-vandal film. There are many shades and types of coating, so there will be plenty to choose from. The main advantages include excellent performance, resistance to any weather conditions and low price of the coating. Doors that lead from the street to the room, it is recommended to coat it with powder coating on both sides, without using wood and materials made from its fibers, so that changes in humidity and temperature do not force frequent repairs;
  
• solid wood– the most expensive, environmentally friendly and beautiful way finishing of the door leaf. Using painting and carving, you can create a real work of art. In addition, the tree will serve as an additional heat insulator;
• made from wood chips, have a thickness of 7-20 mm, covered with paint, a film with a pattern or a thin cut of wood valuable species. Such panels allow you to decorate the door in any way you like, they are not cheap, and the price range depending on the type of decorative coating is decent. Another advantage is good heat and sound insulation qualities;
  
• vinyl leather- once the most popular material for decorative finishing doors. Can be of any color, imitates the structure of natural leather well, inexpensive, but not durable enough;
• – a budget option door finishes, there is a wide choice, they are easy to care for, but their durability is low;
• lamination with PVC film allows you to give the door any pattern, imitate leather or wood. The material is cheap, but short-lived, looks rustic;
• painting and varnishing can even be done independently, but the stability of such finishing is low, as is the price.

In principle, the possible finishing options for the door leaf are not limited to these materials. IN Lately It has become popular to decorate the inside: it expands the space and allows, if it is not large in size.

No. 6. Attention to hinges

When we're talking about When choosing an entrance door, there are no details. The canvas can be three times reliable, and the lock can be cunning and complex, but without good hinges, the apartment will still be easy prey for a burglar.

Today, metal doors are installed these types of loops:

As for the quantity, for a sheet weighing 70 kg (the most common option with a steel thickness of 3 mm) two loops are enough. If the door weighs more or is intended for active use with opening/closing more than 50 times a day, then it is better to install 3-4 hinges. For massive doors, hinges are selected with support bearings, which will greatly facilitate the process of opening the door and avoid squeaks.

No. 7. Features of choosing a lock for a metal door

The front door must be reliably protected not only from “rude” break-ins with a gun, autogen or sledgehammer, but also from attempts at “intelligent” intrusion. Of course, if you choose a door for country house, where they are infrequently visited, then the strength of the structure should be given equal attention, but for an apartment in an apartment building, the cunning of the lock is even more important, because it is unlikely that the noise from forceful opening methods will go unnoticed by the neighbors. However, there is no lock that cannot be opened, especially an experienced thief, so the task comes down to choose a lock that will take as long as possible to open: This will increase the chance that someone will notice the attacker, or he will give up and leave, risking being caught red-handed.

Types of locks for entrance doors:

The ideal pair is level and cylinder locks, and they must be placed at a distance of 25-35 cm from each other. For the front door you only need to choose mortise locks, preferably 3 or 4 safety classes, relying on products from reliable manufacturers. Remember that any lock can be opened, so if an apartment or house can attract “qualified” ones, it is better to install an additional lock.

No. 8. Door security classes

Like locks, entrance doors are divided into classes according to the level of safety and security:

No. 9. Entrance metal door size

The front door, ideally, should be made for a specific opening, and not the opening to be modified under a certain door. Responsible large companies offer their clients a comprehensive service, from measurement to installation, and during production they take into account the individual parameters of the doorway, but such pleasure will cost more than using a standard door.

It is advisable that the door width be more than 90 cm, otherwise large pieces of furniture will be difficult to bring into the room. The design can consist of one leaf, two, or be one and a half – if the opening is wide, then one leaf may not be enough.

By opening method doors can be right or left, external or internal. From a point of view, it is better when the door opens into the room, but this design makes it easier for thieves to gain access to the apartment, because they can squeeze out the door with a 5-ton jack.

No. 10. Manufacturers of metal entrance doors

Only a high-quality door should protect your home. Trusting your home to products from dubious manufacturers means making your apartment vulnerable, and insignificant savings when buying a door can result in dire consequences. At the moment, the largest and most proven are:

• "Elbor" is a domestic company founded in 1993. Today it is the largest enterprise in the sector in the country, has a developed dealer network, and provides warranty service.

Finally

When choosing a metal entrance door, also pay attention to quality of fittings: It’s a shame if it falls apart in a year or spoils the appearance of the door. The eyelet, handles and chains must be functional, practical and reliable. Always put reliability first, not aesthetic qualities.

Choosing an entrance door to an apartment is not an easy task and raises many questions. You need to know what qualities a design should have and what to look for when choosing. The front door is the keeper of the hearth, preventing noise, cold and uninvited guests from entering the home. It should also look presentable, as it acts as the calling card of the apartment.

Requirements for the entrance door to the apartment

Any premises, residential or industrial, greet the visitor with the front door. Choosing an internal opening door for an apartment is not difficult now. However, manufacturers offer a wide selection of products, the differences between which are in materials, dimensions, colors and styles.

Many people are unable to make an informed choice due to the wide variety. This is especially true for those who buy entrance doors to an apartment for the first time. To avoid errors, you should take into account the requirements for any input structures:

1. General reliability parameter. Entrance doors perform many functions, but the main one is to protect your home. For this reason, the chosen design must be durable and high quality, capable of protecting against intruders.
2. It must be possible to inspect the external area. It is better if the entrance door to the apartment is equipped with at least a small peephole. This will allow you to see the situation outside your home or on a flight of stairs.
3. Noise and heat insulation. The product prevents noise and cold from entering the house, increasing living comfort.
4. Appearance. It is better to choose a beautiful entrance door to the apartment so that it is yours style design fit into the interior of the home.

Before you go to the store to buy, you need to consider other points:

1. Price of the canvas. It all depends on the quality of the design. If you choose a door for a summer cottage or an old abandoned apartment, it is not necessary that it be highly durable. Cheaper analogues will also work. But if the product is installed in a new building apartment or a residential country house, then more expensive variations can be considered.
2. Opening dimensions. The canvas should easily “fit” into the doorway. Therefore, before purchasing, you should take all measurements in advance.
3. Selection of accessories. We are talking about locks, hinges, eyes, handles and so on. This takes into account the type of construction and your own preferences. Of course, it is better to choose the appropriate fittings for a good entrance door to your apartment, suitable in quality and style.
4. Availability of certificates and guarantees. This is an important point during the purchase, ensuring that all installation and operation issues are resolved.

Types of entrance doors

On construction market There is a wide range of entrance structures; they also produce designer canvases and technical models. They are classified depending on the material used in their manufacture.

Metal entrance door

This is the most popular type. Manufactured using special technology from durable materials. There are models that are additionally coated with an anti-corrosion compound, which allows the blades to be used in different climatic conditions, extending their service life.

The thickness of the metal sheets also matters: for European entrance doors it is 1 mm, for Chinese ones - from 0.5 to 1 mm, for domestic ones - from 1.5 to 3 mm. The strength characteristics of the entrance structure depend on the thickness of the metal. European models have standardized sizes, while our manufacturers also produce non-classical options.

The customer can choose the design and format of insulation.

Before choosing a metal door for your apartment, you need to familiarize yourself with the classification by level of complexity:

1. Economy class. These are simple and affordable products made from single-sheet steel 1 mm thick. For decoration, only painting is used, without insulation or sound insulation. A separate variety is metal sheets for apartments, assembled from two sheets (each 1 mm thick). For such products, finishing, heat and sound insulation filler is provided.
2. Middle class. These are products made from two sheets, each 1.5 mm thick. The finishing can be any and depends on the customer’s preferences.
3. Elite class. Entrance doors with reinforced construction, with sheet thickness up to 2 mm. They are finished with natural or artificial materials, covered with wood and veneer.

The following finishing materials are used: thermal film, polymer or powder paint, plastic or wooden lining, vinyl leather, auto enamel, varnish, MDF overlays and other materials.

Important! In order for the selected metal entrance door to successfully perform its functions, it is important to install it correctly.

Wooden entrance door

Not long ago, wood was used as the main material for the production of entrance structures. Now the user has a choice, where each product differs in its performance properties. Nevertheless, wooden panels classified as a luxurious and practical classic. Thanks to innovative technologies, their functions and properties have been improved by an order of magnitude compared to the first models, and as a result they last longer.

Wooden products are no longer as popular as before, this is due to the fact that the market offers big choice artificial materials. But some customers prefer natural solid wood. Considering design features, we can distinguish three types of wooden entrance doors:

1. Shield ones. To assemble these products, boards up to 4 cm thick are used. The frame is assembled from solid wood elements glued together. Some manufacturers supplement such entrance doors with an aluminum frame, which not only retains heat, but also extends the life of the product.
   
   
2. Paneled. In terms of design, they are similar to panel ones. They weigh an order of magnitude less, which makes transportation and installation easier.
   
   
3. Whole. This option is now the most common. For production, a solid solid wood is taken.
   
   

What materials are wooden entrance doors made from:

1. Oak. This is a highly durable and durable breed that can last for several decades. Interesting feature– oak hardens over time, which makes the canvas even more stable. The result is the most expensive entrance doors to the apartment.
   
   
2. Ash. Similar to oak, durable and practical material. A popular option due to the variety of colors.
   
3. Beech. It is better to install such a door to an apartment in multi-storey building. Beech does not tolerate moisture well, so it is not used for country houses.
   
4. Pine. The key advantage is the affordable price. Pine - soft material, so canvases from it are made especially for apartments.
   
   

Wooden doors to apartments are preferred by those customers who prefer environmental friendliness and a natural appearance.

Entrance door to an apartment with a mirror

This type is gradually gaining popularity. Many customers prefer just such entrance doors to their apartments, explaining their choice by the small size of the hallway. Nowadays a mirror can be mounted in both wooden and metal products.

An entrance door with a mirror looks organically in any interior, often acting as key element decor. The design is interesting for its decorative effect, but can also perform other functions:

1. Practicality. When leaving the apartment, you can always look in the mirror and evaluate your appearance. Of course, for this you need to correctly place the lighting sources so that the light falls on the person.
2. Visually increases the space. The light, when reflected, creates the illusion of a large corridor.

Important! To ensure the desired effect, you must carefully choose the shape and size of the mirror you install. This will highlight the style of the apartment and decorate the interior.

The mirrors themselves are practical products. Indeed, in a small hallway it is sometimes difficult to place a separate large mirror. But the door panels are just the right size.

Width of the entrance door to the apartment

Standard dimensions are determined by GOST standards, regardless of the material of construction. The main parameters are as follows:

1. Height. Standard parameter is in the range from 2070 mm to 2370 mm. To determine the specific value, the total height of the ceiling and the width of the door leaf are taken into account.
2. Width. The minimum parameter is 910 mm. For single-leaf – 1010 mm, one-and-a-half – 1310, 1510 and 1550 mm, double-leaf – 1910 and 1950 mm.
3. Thickness. There are no strict regulations regarding this value, since everything depends on the material of the canvas for the apartment. The thickness should be sufficient for the front door to perform its main functions.

Important! For entrance structures, the standard size is larger than for interior structures. This is done so that a person carrying a load can freely pass through the opening.

How to choose metal entrance doors for an apartment

The most common are metal structures. Most often, a steel door to an apartment is chosen, which provides adequate protection for the home. There are both global and domestic manufacturers on the market, producing products of different styles and sizes.

Metal has long been used to make entrance doors to apartments. This is the most durable material that provides protection against burglary. For this reason, it is popular for both residential and production premises. When choosing an iron door for an apartment, you should pay attention to the base material. The following metals are used to make products:

1. Aluminum. Such products vary in texture and shades. Aluminum is a metal that is easy to process, so making entrance doors from it is somewhat easier.
2. Steel. This metal is more reliable and durable. In addition to the main function, such entrance panels are equipped with noise and heat insulation. They are more expensive than their aluminum counterparts, but they are also better in quality.

When choosing a product for your apartment, pay attention to the thickness of the base layer - the more, the better design will protect housing. Only two materials are used as a base, but the products differ from each other due to the decorative layer. Used as decoration:

1. PVC panels. Caring for this coating is quite simple.
2. MDF. In addition to being environmentally friendly, this material provides good sound insulation. The most preferred option for office premises.
3. Powder coating. Budget exterior finishing.
4. Panels made from natural wood. Expensive, but environmentally friendly and visually attractive option.

To increase the mechanical characteristics of the entrance door to an apartment, manufacturers equip products with stiffeners. These elements provide protection against deformation and increase burglary resistance. The more stiffening ribs, the more stable the structure will be. It is worth understanding that due to an increase in the number of these elements, the weight increases, which means that the hinges will experience increased loads and fail faster.

What color should you choose for the entrance door to your apartment?

When choosing a color you need to consider general style home decoration, color of flooring material, walls, main furniture. Correct advice that will help you choose the color of the entrance door to your apartment:

1. The best solution is to choose neutral shade, which will not be combined with anything. White, black, gray or beige options look good.
2. It is optimal if the color of the canvas matches the shade of the window frames.
3. Doors decorated with drawings, stained glass or stickers look good. The focus is on design, so compatibility is relegated to the background.

Important! These tips are suitable both for choosing the entrance panel to the apartment and for interior partitions.

Rating of metal apartment entrance doors

The most popular designs are from the following brands:

1. Outpost. This manufacturer produces products at affordable prices. The company is originally from Russia, but production is organized in China, which allowed it to optimize costs. The manufacturing process is controlled, so the products differ good quality, immutability technical parameters and appearance.

5. Became. This is a group of companies that produces entrance canvases for individual orders. A special feature of the products is additional concreting, thanks to which the box is attached much more reliably, while maintaining tightness.

Is not full list companies engaged in the production of entrance doors for apartments.

Where should the entrance door to the apartment open?

In this matter, there is a main requirement - in the event of an emergency, the structure should not create obstacles during the evacuation of people. If we consider practical side, then take several points into account:

• when opening inward, you will have to stop in front of the door and step back to open it;
• the canvas that opens outward is characterized by burglary resistance, since it is much more difficult to knock it out;
• if the product opens inward, it will not be possible to install an additional door, which will not only retain heat in the apartment, but also reduce the noise level;
• if indoors small hallway, it is better to choose the option of opening outward.

In the case of apartment buildings, the following points are also taken into account:

• when swinging externally, the door leaf should not interfere with the opening of a neighbor’s door;
• if the apartments open onto a common vestibule, then the vestibule door is opened outward, and the entrance door is opened inward;
• if during opening the door touches something, for example, a counter, then it is supplemented with an opening limiter.

For the most part, where the canvas will open is the decision of the apartment owner.

Conclusion

Choosing an entrance door to an apartment is not a problem, since there are many offers: metal, wooden crafts or designs with mirrors. The main thing is that the door provides adequate protection for the apartment and at the same time matches the interior of the room. You can take into account the rating of the entrance metal doors to the apartment, but it is equally important to install the door correctly.

Choosing an entrance door is a rather important moment, since the safety of all the property of the house or apartment, and sometimes the life of the owners, will depend on its design. Today, the assortment of specialized stores is formed by many manufacturers presenting their products, which have a wide range of prices - from the most modest to the very high. Therefore, you can always choose a door that will fully meet the capabilities of the homeowners.

The purpose of the front door is not only to protect the home from intruders, as it should prevent the penetration of external noise and cold air masses. In addition, there are models that can create a reliable barrier even intense flames during a fire. How to choose a metal entrance door - advice from a professional - they are necessarily given depending on where it will be installed: at the entrance to the apartment or in a private house, as well as taking into account many criteria that directly affect the performance of this design.

Criteria for choosing an entrance door

To clarify all the nuances, we turned to the Moscow manufacturer of entrance doors, the ProfMaster company, where more than 80% of orders are individual production "to order", because this is the only way to choose a door without compromising on quality.

There is a list of main points that you need to pay special attention to when purchasing an entrance door:

• Installation location. The door can be installed on the street in a private house or at the entrance to an apartment, that is, in an entrance area protected from direct external influence. The choice of insulation material and external cladding will depend on this.
• Level of protection. Several aspects can be attributed to this criterion:

- the thickness of the metal used to make the door;

— frame design;

— the number of metal layers in the door leaf;

— the number of stiffeners inside the canvas frame;

- number and design of locks and hinges;

— presence of an overview element.

• Insulation material. To prevent the door from letting in cold masses and extraneous noise, it is insulated with mineral wool, polystyrene foam, polyurethane foam or cardboard. Some cheap models may have no insulation at all.
• Number of seals. They can be installed on the door leaf or frame, in one, two or even three rows. For fire-resistant structures, sealing contours made of special materials are used.
• Door weight. Quality product should be heavy, as it has reliable stiffening ribs and is made of high-quality, fairly thick metal sheet.
• A design solution that will harmoniously fit the door into the overall design of the facade if the door is installed in a private house.
• Fireproof qualities of materials, if you plan to purchase a door that has protection against the spread of flame.
• Anti-vandal coating - especially necessary if there are animals in the house that can scratch door trim, or in an apartment where there is no combination lock at the entrance to the entrance.
• The door must have a quality certificate or product passport, which will indicate all its characteristics.

Assessment of the main characteristics of doors

The price of such products is quite high, but you can be sure of the safety that they will fully provide. Therefore, recently more and more apartment residents and house owners prefer this particular door option.

So, the design of the entrance doors must fully meet all the criteria for safety and comfort when opening and closing them, as well as satisfy homeowners in terms of its design. Therefore, when making a choice, you need to make a list of requirements for the door structure in advance, and if the model meets them, then this option will be ideal for a specific entrance to a building or apartment.
