How to choose a reliable entrance metal door. How and what to choose the front door: we select the best option for the apartment

The front door in the apartment serves not only as a "security barrier", but also as a kind of hallmark of the owners of the premises. It is difficult to decide what to first of all be guided by when choosing: the technical characteristics of the structure, its appearance or the manufacturer's rating. How to choose an entrance door to an apartment that will meet security requirements, provide comfort in a living space and satisfy aesthetic needs? To purchase a door that meets these parameters, it will be useful to consider in detail all aspects of the choice.

To decide which front door is better to put, the choice must be justified, first of all, by the good reliability of the structure, the main elements of which are the box and the canvas.

door frame

For the manufacture of the box, manufacturers use a bent sheet, corner or profile pipe. The construction of a profile pipe with one weld has the highest strength parameters, since a bent sheet and a corner are less resistant to bending, twisting and deformation. But it must be taken into account that the thickness of the metal is also important: the optimal cross section is 3–5 mm. The number of welds also affects the reliability of the door frame: the more there are, the less durable the structure is considered.

The frame must have a threshold. A U-shaped box without a lower link is not able to provide strength to the structure.

mounting hole Mounting plate

For fasteners in the frames there are holes or special mounting plates. The second option is preferable, since it eliminates the possibility of cutting fasteners. There are two options for fastening door frames: anchor bolts or steel pins. As a rule, their number should be at least three on each side. The minimum diameter of the fasteners is 12 mm, the length is not less than 15 cm.

The next element of the box that you should pay attention to is the door porch. It is used for mounting sealing material. On sale you can find designs with one, two and even three vestibules. Since we are choosing a new entrance door to the apartment, it makes no sense to overpay for a complex structure: one porch is enough, but you should not save on the sealant - the better its quality, the longer it will last and provide protection from drafts and extraneous sounds.

An equally important element of the door frame is the platbands. They perform not only a decorative, but also a protective function, blocking access to the mounting elements.

Door leaf

Now let's figure out what parameters you need to choose a door leaf. It consists of a rectangular frame to which the outer and inner panels are attached. The outer panel is necessarily made of steel, but for the inside, manufacturers can use not only metal, but also a panel made of MDF, solid wood, chipboard with veneer, laminated film or leatherette. Since the front door to the apartment does not have to be exposed to atmospheric influences, you can choose any of these options. The optimal parameters for the thickness of the outer steel sheet are 1.5–2.5 mm.

Stiffeners are located inside the door leaf. Their minimum number is three. In low-cost designs, two vertical ribs and one horizontal rib should be present. The highest quality designs are those in which the number of ribs exceeds the minimum limit: two vertical and four horizontal elements will significantly increase the reliability of the front door. At the same time, the more elements the structure contains, the heavier it is in weight, which means that the load on the hinges increases. In order not to subsequently face such a task as tightening loops or replacing worn parts, it is better to choose a product in which the stiffening ribs are made of long rolled products and have a complex profile. They are lighter in weight and more resistant to bending.

Locks

Even the best front doors will not be secure without a good lock. Locking structures that would be impossible to open still do not exist, and yet, two locks of various types, breaking which will take a lot of time, can discourage an attacker from entering someone else's apartment.

For entrance doors to an apartment, it is better to choose two locks that differ in design. As the main locking mechanism, one should consider a device with crossbars that fix the door leaf in several directions.

Most often on steel doors you can find locks of two designs:

• The cylinder locking mechanism is quite difficult to open, but is not resistant to the use of brute physical force. An armor plate can complicate the process of knocking out the lock.
• With a special tool and certain skills, a lever lock can be opened, but it will not be easy to disable it with the use of force: the structure is located inside the door leaf and takes up a lot of space. The level of secrecy of lever locks is constantly being improved.

Security elements

The opening side of the sash is very important in terms of reliability. The preferred option is external opening. In this case, the sash is much better protected from being knocked out and squeezed out by a jack. The strength and reliability of the front door also depends on small structural elements.

Door hinges

Outer loop Hidden loop

Loops are external and hidden. The outer ones are welded to the rack of the box and the canvas, and the hidden ones are located in special sinuses, which cannot be accessed from the outside. Buying a door with hidden hinges will cost more, but is there a need to overpay? The only drawback of open loops is their location, however, the burglary resistance of the structure does not suffer from this at all. Cutting loops is a noisy process. It is unlikely that attackers will want to draw attention to themselves. In addition, there is such a security element as anti-removable pins that will protect the door from breaking even with cut hinges.

Hidden awnings affect not only the increase in the cost of the door, but also have other disadvantages:

• due to the design features, the width of the doorway is slightly reduced;
• reduce the opening angle of the sash;
• reduce the strength of the frame by organizing a niche inside the box:
• during operation, they can cause deformation of the box when the door is opened at an angle exceeding the parameters allowed by the design.

The next aspect of the choice that the buyer has to face is adjustable or non-adjustable hinge designs, which one is better? In the first case, repair of worn hinges is possible, in the second - no. In fact, adjustable hinges can be an additional problem as they tend to loosen over time. An unregulated structure cannot be repaired, but ruining such hinges is a difficult task.

When you go to the store to choose a door for your apartment, it is important to make sure that the hinges can handle the load ahead. If the weight of the structure exceeds 100 kg, it is desirable that it be equipped with three canopies. A support bearing must be present in the design of the hinges - it facilitates operation and has a positive effect on the durability of the canopies.

Anti-removable pins

This type of protection is an anchor system. The pins are located on the end sections of the sash. When the door is closed, the anchors are immersed in the holes located in the box. As a result, the door leaf remains fixed in the frame even if the hinges are cut off.

Internal gate valve

This mechanism will provide the owners with peace of mind when they are at home. The latch is installed on the inside of the door and it is not possible to get close to it from the outside. It is operated manually.

Insulating properties

The thickness of the metal, the number of loops and the design of the locks are all technical aspects. No less important is the comfort inside the apartment, which also largely depends on which entrance doors you have installed. The noise of a working elevator, tobacco smoke and other “pleasures” of a densely populated high-rise building do not go well with the concepts of home comfort and peace. How to choose the right front door to the apartment to protect yourself from extraneous sounds, smells and drafts? These problems should be dealt with by isolation.

Inside the door leaf, the insulating material must tightly fill all the voids between the stiffeners. Since we select doors not for a house, but for an apartment, where the structure will not suffer from temperature and humidity changes, there are no special requirements for the insulation material. It can be mineral wool, polyurethane foam or expanded polystyrene. All these materials provide noise absorption, serve as good heaters.

Hidden loop

Another loophole for noise and smell is the perimeter of the door. It is protected with a rubber or silicone seal.

All these measures will be ineffective if violations are made during the installation of the structure. There should be no gaps between the box and the wall. Of course, no sealing material is able to create perfect silence, since sounds propagate through the walls, but the comfort from installing a high-quality front door will be palpable.

Exterior finish options

When we're trying to decide which front door to choose, looks are as important as strength and cost. Beautiful finishes are pleasing to the eye and able to brighten up the interior, while it would be nice if the design you choose is strong and durable. Consider the advantages and disadvantages of the materials that can be used to frame the front door to the apartment, decide which decorative finish to choose.

Leatherette

Thanks to special fastening pads, which facilitated the process of "upholstery" of the steel sheet, leatherette is quite often used as a finish for metal entrance doors. The disadvantage of this material is its poor resistance to mechanical damage. It can be accidentally damaged by a sharp object. Advantages - a wide choice of color options and textures, the ability to create an original pattern on the surface using wire, additional sound insulation through the use of foam rubber or batting as a lining.

Decorative panels

Plastic or wood overlay panels are a relatively new and very popular type of finish. They have a three-dimensional or flat pattern, a large range of colors. The strength threshold for this finish is also not very high. Manufacturers offer products with additional plastic coating, but this procedure increases the cost of products.

Painting

The advantages of hammer painting are resistance to mechanical stress and aggressive liquids (as a result, ease of maintenance with the use of cleaning products). The paint gives the surface a three-dimensional structure, is easy to apply, dries quickly, has an extensive range of colors. This type of finish is most suitable if you have to choice of front door for a cottage.

Manufacturer rating

Where to buy the best entrance doors to an apartment, and which manufacturers can you trust? Be sure to take into account the fact that large manufacturers, unlike small private companies, provide a guarantee. If you purchase a door from a dubious one-day company, the chance to replace a part that has worn out ahead of time, or even a hidden design defect, is reduced to zero for free. In addition, handicraft products are difficult to check for quality - which doors are strong, what metal thickness was used in them, insulation material, etc., while the technical parameters of a factory product are specified in its passport.

It is generally accepted that European doors are better in quality than products of domestic companies. But do not forget that products, both domestic and foreign, are designed for consumers with different income levels.

• Economy class - products with a low market value, designed for people with low incomes. Meets minimum safety requirements.
• Standard - designs with high-quality exterior finish, made of durable metal. They have an average level of cost due to savings on fittings and locks.
• Business class and premium class are expensive luxury products that are most often developed on an individual order.

If we take into account such a gradation of products and the cost of delivery from abroad, it becomes obvious that domestic standard class entrance doors will cost about the same amount as economy class products manufactured abroad. And here it is up to you to decide what is more important: reliability, or which company the product has a stigma.

• The Guardian has been manufacturing steel doors since 1994. Offers standard and non-standard products, own fittings. Products comply with GOST 31173-2003. The warranty period is at least three years.
• Forpost offers a wide range of economy, standard and business class products. Many models have hidden loops that are protected from cutting. The range includes reinforced steel doors, 2.2 mm thick.
• Condor - durable, strong, reliable doors. Large model range. Modern design, rich colors. Products have an affordable cost, it is possible to purchase a high-quality door of the "standard" class on sale at a discount.
• Torex supplies beautiful models with good sound insulation, high reliability and durability parameters. Production lines are equipped with new imported equipment.
• Elbor is a brand known since 1993. Production is on a wide scale. The products are equipped with fittings of our own production, they have III-IV class of burglary resistance.

Summing up

After a detailed review of how to choose the front door to an apartment, we will compile a short list of the main aspects that you should rely on when buying:

1. The steel from which the door is made must have a thickness of 1.5 to 2.5 mm.
2. The optimal number of stiffeners is 6. Four of them are located in the horizontal direction, two - vertically.
3. The design must have a vestibule.
4. The most durable and durable will be hinges with a bearing. The number of hinges depends on the weight of the sash, if it exceeds 100 kg, the load should be distributed over three hinges.
5. A sealant is needed around the perimeter of the box.
6. The greatest degree of protection against burglary will provide two locks: level and cylinder.
7. The armor plate on the lock and anti-removable pins increase resistance to burglary.
8. The box, which is made of a profile pipe and has only one weld, is considered the most durable and reliable.

We hope that choosing the front door using these tips will be easier for you.

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

Requirements for the entrance door to the apartment

Any premises, residential or industrial, meet the visitor with the front door. It is not difficult to choose the front door of internal opening to the apartment now. Nevertheless, manufacturers offer a wide range of products, the difference between which is in materials, dimensions, colors and styles.

Many people are not able to make a competent choice due to the large variety. This is especially true for those who buy entrance doors to the 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 ensure the protection of housing. For this reason, the design chosen must be durable and of high quality, able to protect against intruders.
2. It should be possible to inspect the outer territory. It is better if the front door to the apartment is equipped with at least a small peephole. This will allow you to see the situation outside the housing or on the flight of stairs.
3. Noise and heat insulation. The product prevents the penetration of noise and cold into the house, increasing the comfort of living.
4. Appearance. It is better to choose a beautiful front door to the apartment so that it fits into the interior of the home with its style design.

Before you go to the store for a purchase, you need to consider other points:

1. Canvas price. It all depends on the quality of the design. If you choose a door for a summer cottage or an old abandoned apartment, then it is not necessary that it be high-strength. Cheaper alternatives will work as well. 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 "enter" the doorway. Therefore, before buying, you should take all measurements in advance.
3. Choice of accessories. We are talking about locks, hinges, eyes, handles and so on. It 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 the apartment, suitable in quality and style.
4. Availability of certificates and guarantees. This is an important point at the time of purchase, ensuring that all installation and operation issues are resolved.

Types of entrance doors

A wide range of input structures is presented on the construction market; designer canvases and technical models are also produced. They are classified according to the material used in the manufacture.

metal front door

This is the most requested type. They are made 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 under different climatic conditions, extending their service life.

The thickness of metal sheets also matters: for European entrance doors it is 1 mm, Chinese - from 0.5 to 1 mm, domestic - from 1.5 to 3 mm. The strength characteristics of the input 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 to an apartment, you need to familiarize yourself with the classification according to the level of complexity:

1. Economy class. These are simple and affordable products made of single-sheet steel with a thickness of 1 mm. As a design, only painting is used, without insulation and soundproofing. A separate variety is metal sheets in an apartment, assembled from two sheets (each 1 mm thick). For such products, finishing, heat and sound insulating filler is provided.
2. Middle class. These are products made from two sheets, where the thickness of each is 1.5 mm. Finishing can be any and depends on the preferences of the customer.
3. Elite class. Entrance doors with a reinforced structure, with a thickness of sheets up to 2 mm. They are finished with natural or artificial materials, sheathed with wood, veneer.

As a finish, they use: thermal film, polymer or powder paint, plastic or wooden lining, vinyl leather, car enamel, varnish, MDF lining and other materials.

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

wooden front door

Not so 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 operational properties. Nevertheless, wooden canvases are classified as luxurious and practical classics. Thanks to innovative technologies, their functions and properties have been improved by an order of magnitude compared to the first models, as a result they last longer.

Wooden products are no longer as popular as they used to be, this is due to the fact that a large selection of artificial materials is offered on the market. But some customers prefer the natural solid wood. Considering the design features, three types of wooden entrance doors can be distinguished:

1. Shield. To assemble these products, shields 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 shield ones. They weigh an order of magnitude less, which facilitates transportation and installation.
   
   
3. Whole. This option is now the most common. For manufacturing take a solid array of wood.
   
   

What materials are wooden doors made from?

1. Oak. This is a high-strength and durable breed that can last for several decades. An interesting feature is that oak hardens over time, which makes the canvas even more stable. The result is the most expensive entrance doors to the apartment.
   
   
2. Ash. By analogy with oak, a 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 a multi-storey building. Beech does not tolerate moisture, so it is not used for country houses.
   
4. Pine. The key advantage is the affordable price. Pine is a soft material, so canvases from it are made purely for apartments.
   
   

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

Entrance door to the apartment with a mirror

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

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

1. Practicality. Leaving the apartment, you can always look in the mirror, evaluating your appearance. Of course, for this you need to correctly place the light sources so that the light falls on the person.
2. Visually enlarges the space. Light, reflected, creates the illusion of a large corridor.

Important! To ensure the desired effect, it is necessary to carefully choose the shape and size of the mirror to be installed. This will emphasize 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.

The width of the entrance door to the apartment

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

1. Height. The standard parameter is in the range from 2070 mm to 2370 mm. To determine a 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 - 1910 and 1950 mm.
3. Thickness. There are no strict regulations regarding this value, since it all depends on the material of the canvas for the apartment. The thickness should be enough for the front door to perform its main functions.

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

How to choose entrance metal doors for an apartment

The most common metal structures. Most often, a steel door to an apartment is chosen, which provides adequate protection for housing. 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 an apartment. This is the most durable material that provides protection against burglary. For this reason, it is popular for both residential and industrial premises. When choosing an iron door to an apartment, you should pay attention to the base material. For the manufacture of products using the following metals:

1. Aluminum. Such products are different 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 canvases are equipped with noise and heat insulation. At a price they are more expensive than aluminum counterparts, but the quality is better.

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

1. PVC panels. Caring for such a coating is quite simple.
2. MDF. In addition to environmental friendliness, this material provides good sound insulation. The most preferred option for office space.
3. Powder coated. Budget exterior.
4. Panels made from natural wood. Expensive, but environmentally friendly and visually appealing option.

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

What color to choose the front door to the apartment

When choosing a color, it is necessary to take into account the general style of housing design, the color of the floor material, walls, and basic furniture. The right tips to help you choose the color of the front door to the apartment:

1. The best solution is to choose a neutral shade that will go with nothing. 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 windows or stickers look good. The bias is made on design, so compatibility is relegated to the background.

Important! These tips are suitable for choosing the entrance canvas to the apartment, as well as for interior partitions.

Rating of entrance metal apartment doors

The most popular designs of the following brands:

1. Outpost. This manufacturer produces products at a reasonable price. The company is originally from Russia, but production is organized in China, which made it possible to optimize costs. The manufacturing process is controlled, so the products are of good quality, unchanged technical parameters and appearance.
2. Torex. The company has been producing entrance doors to apartments for over 25 years. Thanks to solid practical experience, the fabrics produced have good consumer properties, without overpayment. The range includes fire protection options.
3. Elbor. The year the enterprise began its activity is 1976. Not so long ago, a comprehensive modernization of the company was carried out, which made it possible to increase production capacities.
4. Guardian. A distinctive feature of the products of this company is the high price, but consumer properties correspond to the premium class. For the manufacture of entrance doors to the apartment, strict international and domestic standards are taken into account.
5. Became. This is a group of companies that produces entrance canvases for individual orders. A feature of the products is additional concreting, thanks to which the box is attached many times more reliably, while maintaining tightness.

This is not a complete list of companies manufacturing entrance doors for apartments.

Where should the front 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 for the evacuation of people. If we consider the practical side, then take into account several points:

• when opening inward, you will have to stop in front of the door and step back to open it;
• the canvas that opens outwards 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 put an additional door, which will not only keep the heat in the apartment, but also reduce the noise level;
• if the room has a small entrance hall, it is better to choose the option of opening to the outside.

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

• when plowing outside, the canvas should not interfere with the opening of the neighbor's doors;
• if the apartments open to a common vestibule, then the vestibule door is opened outward, and the entrance door is opened inward;
• if during the 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 owner of the apartment.

Conclusion

Choosing an entrance door to an apartment is not a problem, as there are many proposals: these are metal, wooden products or structures 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 properly install the canvas.

It will not work 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, which are significantly superior to wooden counterparts in terms of protection and safety. However, the door of the door is different - The modern market is so oversaturated with various options., which can be found both flawlessly and one that even an inexperienced burglar can easily crack. How to choose a metal front door so that it provides, pleases with its appearance and impeccable service? Let's stop at the most important points that everyone should know before going to a store or a specialized company.

Attention! In the process of reading our material, you will understand that when choosing a front door, there are a lot of nuances and all of them are 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 event that you are not ready to compromise and are ready to pay for a quality door according to your optimal characteristics, it is better to make a custom-made door directly from the manufacturer, where you can stipulate and write down all future nuances in the contract.

No. 1. Design features of a metal door

The strength and reliability of the door to some extent depends on the characteristics of each of its constituent elements:

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

Door leaf made from 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 is dark in 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 it will cost more, but in terms of performance, this is the best option - no atmospheric effects are terrible for the material.

The strength is also significantly affected by the framework.. The most reliable will be the door in which the frame is made from a profile pipe with one seam. Less durable is a frame made of four sections of hot-rolled shaped pipe-rolling, among themselves. The most unreliable will be the frame, in which each of the four segments is welded from two corners of the same length. Simply put, the fewer welds in the frame, the better, because each of them reduces the resistance to mechanical stress. The outer part of the door leaf must be made only of monolithic non-welded sheet, otherwise a blow with a sledgehammer of medium strength 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 setting may fluctuate 0.8 to 5.0 mm: the higher it is, the more reliable and durable the door will be. Along with the increase in security, the price and weight increase, which is also important to consider.

The scope of use of doors with different thickness of steel sheet is significantly different:

Some manufacturers use steel sheet only on the outside, insisting that this is enough to create a solid structure and making the inner panel, for example, from MDF. To be completely sure of your 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, is the ideal of strength. Such doors are much more expensive than their simpler counterparts, weigh more and will by the way not 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 steel sheet or even - this is a huge plus in terms of reliability, even if the door is made of not very thick steel sheets.

Number 3. Number of stiffeners

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

The minimum set of stiffeners is two vertical and one horizontal. It is better if there are more of them, but without busting, 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, therefore, earlier, when metal doors just began to appear in the domestic space, it was common practice to put two at once: one - metal to protect against unauthorized access, the second - wooden to keep heat in the apartment . Today the situation has changed significantly: although there are cold bridges in a metal door (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 all the space between the outer and inner sheet. Most often in the production of steel doors, the following heaters are used:

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

It is important that the manufacturer also fills the internal cavities of metal profiles with insulation, otherwise it is not necessary to talk about high thermal insulation qualities. It is not difficult to check this - just tap on 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

Steel sheets of the door leaf need decoration. When choosing interior finishes it is worth starting only from personal preferences and nuances of arrangement. Exterior finish 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 when the door leads to a vestibule or entrance, there are no special requirements for its external decor.

Most popular finishes:

• powder coating involves the application of special paints to the surface, which, under the influence of high temperature, form an anti-vandal film. There are a lot of shades and types of coverage, so there will be plenty to choose from. Among the main advantages are 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 cover with powder coating on both sides, without using wood and materials created 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 to finish the door leaf. Using staining and carving, you can get a real work of art. In addition, the tree will serve as an additional heat insulator;
• made on the basis of wood chips, have a thickness of 7-20 mm, covered with paint, a film with a pattern or a thin cut of valuable wood. Such panels allow you to decorate the door as you like, they are not cheap, 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 door trim. It can be of any color, it imitates the structure of genuine leather well, inexpensive, but not durable enough;
• - a budget option for finishing the door, the choice is wide, their maintenance is simple, but the durability is low;
• pvc film lamination 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 performed independently, but the stability of such a finish is low, as is the price.

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

No. 6. Focus on hinges

When it comes to choosing a front door, there are no trifles. The canvas can be three times reliable, and the lock can be tricky 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, then for a web weighing 70 kg (the most common option with a steel thickness of 3 mm) enough for two loops. 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 pieces of hinges. For massive doors, hinges are selected with support bearings, which will greatly facilitate the process of opening the leaf and avoid squeaks.

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

The front door must be reliably protected not only from "rough" breaking with, autogenous or a sledgehammer, but also from attempts at "intelligent" intrusion. Of course, if a door is chosen for a country house, where they are rarely visited, then equal attention should be paid to structural strength, but for an apartment in an apartment building, the trick of the lock is even more important, because it is unlikely that the noise from power opening methods will go unnoticed by neighbors. However, there is no lock that cannot be opened, especially to an experienced thief, so the task is to ensure that 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 perfect pair is lever and cylinder locks, and they must be located at a distance of 25-35 cm from each other. For the front door, it is worth choosing only mortise locks, and preferably 3 or 4 security classes, relying on products from reliable manufacturers. Remember that any lock can be opened, so if an apartment or house can attract "qualified", it is better to put it in addition.

No. 8. Door security classes

Like locks, entrance doors are divided into safety and security classes:

No. 9. The size of the entrance metal door

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

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

By way of opening doors can be right and left, external and internal. From the point of view, it is better when the door opens inside the room, but this design simplifies the access of thieves to the apartment, because they can squeeze out the canvas with a 5-ton jack.

No. 10. Manufacturers of entrance metal doors

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

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

• "ProfMaster"- a small, relative to other eminent competitors from the list, trading and manufacturing enterprise. The company has been operating since 1998 and is known to the consumer thanks to the popular street doors of the Nord series. The peculiarity of the company is that it is aimed at the individual production of doors under the customer's order. Here they can make almost any entrance door at the request of the customer, which is not to be expected from large manufacturers who manufacture doors on a conveyor strictly in accordance with their model range. The company operates in the Moscow market, but delivers some individual products directly to customers in neighboring regions by a transport company.
• "Guardian" is a large holding operating since 1994. The structure includes several enterprises of different fields of activity, incl. CJSC "Portal", specializing in the production of doors.

• Dierre- an Italian company known for its advanced developments in the field of door protection. At the moment, the manufacturer is working on creating;
• Gardesa is an Italian company with several representative offices in Russia. The quality and price are high, the manufacturer uses the locks of the best Italian companies, which are developed for him on an individual order;
• Galant and Novak- Polish companies offering good doors at reasonable prices, but domestic counterparts are not inferior to them in quality.

Finally

When choosing a metal front door, also pay attention to hardware quality: it's a shame if it falls apart in a year or spoils the appearance of the door. The peephole, handles and chains must be functional, practical and reliable. Always prioritize reliability over aesthetics.

A metal front door is undoubtedly necessary for a modern apartment and house. Its main function is to protect against uninvited guests. The first thing that a guest or visitor of an institution can pay attention to is an iron door. Its quality indicates a serious approach to home improvement, gives solidity to the organization. Its function is also to prevent the release of heat from the premises in winter and to keep the building cool in summer.

Manufacturers vying with each other talk about a large assortment of metal products, so it will not be easy for an inexperienced buyer to make a choice of a metal door. However, it is doubtful that a cheap product will please with excellent quality. The cost of developing a design, manufacturing a product from high-quality metal alloys affects the price, and a strong, reliable input unit will not be cheap. This is the main reason why the buyer devotes a lot of time to the question of how to choose an entrance metal door.

You can find a wide range of high quality entrance and interior doors at the best price in the Glorious Doors store.

Naturally, the protective function will be the main one. Which design solutions are better to choose will depend on the minimum required security function. For an ordinary apartment, there is no point in greatly overestimating the strength of the structure, since a large weight increases the wear of the hinges and box fasteners.

On sale you can find a wide variety of entrance doors, how to choose the best option? It is better to choose doors based on the required strength (canvas, locks, fasteners), aesthetics and as an additional element of insulation and soundproofing of interior spaces. To decide which protection option will be optimal for a given case, consider the main protection indicators.

Features of steel processing

Steel for door structure can be processed in two ways, and the choice of method will greatly affect the final quality of the product. Referring to the documentation and certificates, you can see one of the values:

• GOST 19903– hot-rolled and more susceptible to environmental degradation steel sheet. It will quickly rust and corrode.
• GOST 19904- cold-rolled and more resistant to the environment steel sheet. It makes the finished product more expensive and of higher quality.

metal thickness

The choice of a steel door is also determined by the thickness of the metal. The reliability class of the product depends on this value, which tells about the resistance of the structure to hacking methods.

The thickness of the steel sheet should not be less than 2 mm. If this value is not met, then the structure can be installed in non-residential premises in which no valuables are stored (for example, a household room for cleaning equipment). A metal door to an apartment or residential building should be purchased with a sheet thickness of at least 2, but not more than 4 mm. Otherwise, it can be very heavy and not very convenient to use.

More about reliability class

Entrance doors are distributed according to reliability classes. This is reported by GOST R 51072-97, which provides for 13 classes of entrance doors. Among them, constructions from classes 1 to 4 are suitable for apartments and houses, and values ​​​​above 4 are used for special purposes (banks and premises for storing valuables).

Characteristics of products from the first to the fourth class:

• The first is that the design withstands physical force without additional tools.
• The second is against simple tools such as a screwdriver.
• The third is resistant to the use of scrap.
• Fourth - withstand blows with a hammer, ax, drill.

It goes without saying that this refers to the door leaf and is not related to the quality of the lock. The value of the reliability class for each specific product can be clarified in the store. If the seller does not have data on determining the reliability class of any model, then most likely it has not been tested, and the quality may be doubtful.

Stiffening rib

The quality of entrance metal doors is greatly influenced by the number of stiffeners. These are metal elements that are under the outer sheet and are installed to enhance protection. The best entry structures will have more than two vertical and one horizontal stiffeners.

However, with an increase in their number, the weight of the entire block increases. In order to reduce weight, modern stiffening ribs have a non-standard shape, which allows you to maintain the strength of the product and reduce the weight load on the hinges.

Door frame (frame)

Entrance metal doors can have various options for internal filling. Among them, there are several ways to make a frame.

• A frame made of a single pipe bent in four places, the ends of which are welded to each other.
• A variant of four straight pipe sections welded together into a single box.
• Four corners that are joined together by welding. Each of the segments consists of identical corners welded together. This version of the frame is considered the most unreliable.

As you can see from this list, the first frame option with the fewest welds is the best. The design with the appearance of each new weld can become skewed and change the originally conceived geometry. Putting a box with a minimum number of welds is the best option.

Web material

The door leaf is made of steel, inside it has stiffening ribs and a frame. The side facing the dwelling may have an additional layer of aesthetic material.

• The full metal structure is suitable for external entrance to the building. For example, it could be the entrance to an organization or the door to a private home.
• A canvas with an additional inner layer of wood, MDF or leather upholstery is suitable for a door to an apartment . At the same time, the inner layer will not quickly deteriorate due to a sharp temperature difference between the rooms.

loops

You need to choose a metal front door with knowledge of the features of the hinges. They, like the canvas, will help protect the room from burglary. The design uses two types of loops:

• hidden,
• outdoor.

Hidden hinges automatically eliminate the possibility of removing the sash and entering the apartment. The outer ones can be cut off, so the hinges of the entrance doors are additionally equipped with anti-removable devices: pins or tongues. Pay attention to the presence of these devices in the selected design.

A standard canvas weighing less than 70 kg is mounted on two hinges. If you plan to frequently open and close the sash, or the canvas is over the standard weight, you should take care to install 3-4 loops. The supplied thrust bearing will help the hinges work for a long time and with high quality.

Lock

How to choose the right front door with locks? The option with two locks of different devices is recognized as optimal:

• one padlock for closing briefly,
• a second lock of a more complex design during a long absence of the owner.

Castles are:

• cylinder, based on a pin mechanism, and they are easily cracked by drilling a cylinder;
• lever locks, the most reliable of which are locks with a large number of levers (steps on the key minus one);
• electronic - the most modern and expensive.

As a standard, two cylinder locks or one cylinder and one lever lock are installed in the entrance structure. An electronic lock can be installed optionally. It is worth considering some features that will help eliminate a possible hacking of the lock:

• it is better to choose a lock in which the number of crossbars and pins is the largest;
• it’s good if the lever lock has a manganese insert, which will be additional protection against hacking;
• if the locking bolts are hidden, cutting them will become impossible;
• the armor plate of the lock will make it impossible to cut the core.

It is also worth remembering that cylinder locks do not tolerate mechanical shocks well.

Warming and soundproofing

Consider which metal doors and better keep the heat inside and the noise outside. By itself, the metal structure will not be able to create good thermal insulation, and manufacturers are concerned about the creation of heaters and rubber seals. In production, thermal insulation is laid in the space between the outer and inner sheets of steel. An additional layer of rubber or foam rubber seal is laid in two areas where the door frame and leaf join in the position of the closed door.

• It is worth clarifying whether there is a layer of insulation in the frame. If it is present there, the thermal insulation will be better.
• A rubber seal in the form of a tape will not be as good as a tube seal. The wear resistance of the tubular seal is higher.

Appearance

A peephole that has already become traditional should provide a wide view, a clear and sharp picture. In addition to the peephole, modern manufacturers make it possible to purchase doors with an already built-in video peephole, from where the image is transmitted directly to the home computer.

Aesthetics

Modern front doors are very different from their counterparts twenty to thirty years ago. If necessary, you can choose both a massive and elegant version without sacrificing strength. The outer surface can be covered with paint, and the best coatings for the inner surface are:

• leather,
• leatherette,
• laminate,
• veneer,

A variety of colors and textures allow you to beat the room the way the owner wants. The front door as just a room guard is already considered an outdated option. Modern entrance structures fit perfectly into the design of the room. Aesthetics and harmony of style begins with the design of the entrance.

In an apartment building, it may make sense to paint the outer side of the sash in the color of the rest of the entrance doors so as not to attract unnecessary looks. It is also possible to apply an anti-vandal coating on the canvas, which will protect it from external damage.

Imported products are kept apart: the designs are solid, but expensive, the price for products of Polish, Italian, German manufacturers starts from 30 thousand rubles and ends with disappointing six-digit numbers.

How to choose entrance doors to an apartment or? Each of us has our own idea of ​​products. But everyone considers reliability, quality and design to be the main qualities. You can also secure the apartment from intruders with additional actions: hold, put the apartment on guard and install. These are additional costs that can be avoided. However, there are nuances that affect reliability. It is warm and burglar resistant. To select the best product, we conducted a market analysis and compiled a rating of entrance doors to the apartment and consumer reviews to help you make the right decision.

The first thing you should pay attention to is the door material. Most often used in the production of wood or metal. Let's take a look at the features of each. High-quality entrance wooden doors to the apartment are expensive. They are quite reliable, it is such products that create prestige for their owners. Not every wood is suitable for making a quality structure. Better to use:

• ash;
• red and black tree.

Products made from other types of wood are significantly inferior in strength and performance. In this case, it is better to purchase doors made of metal. The price range is different. How not to get confused and know what to look for when choosing, we will tell further.

Main technical parameters of entrance doors

The front door must meet two criteria - reliability and security. Therefore, when choosing, it is important to consider the thickness of the base and the outer sheet. It is important that the structure has stiffeners. It would seem that the higher these parameters, the better. Excess weight will wear the hinges due to rapid inertia when opening.

Consider the main characteristics of metal entrance doors to an apartment in more detail.

Sheet thickness

Not every metal is suitable for front doors. Medium-carbon and medium-alloyed alloys are considered optimal. You can check the thickness of the sheet in the technical passport, while you should know the main classification:

The optimal weight of the product should be within 70 kg. Structures weighing about 100 kg are installed in banks.

Web design

The canvas consists of a rectangular frame with two steel sheets. Manufacturers sometimes replace the inner panel with MDF or veneer. If, you should choose a completely metal structure, since temperature changes and humidity will quickly render the wooden panel unusable.

It is obligatory to install cashing from steel and vestibules, which will hide all areas and protect the premises from unauthorized entry.

Stiffeners are installed between the sheets. The minimum set is 2 vertical and 1 horizontal. With an increase in their number, the reliability and weight of the structure increase.

Locks

When choosing a product, it must meet the following criteria:

• The quality of the lock must match the door. A model assembled from cheap materials will not protect even the most expensive structure from hacking. And, conversely, it is useless to put a premium-class lock on Chinese products;
• a mortise lock is needed for the front door, overhead models will not work. A latch is required;
• manufacturers install 2 locks. This is necessary in order to protect against burglary, because it is much more difficult and longer to open two locks for a robber. There is another reason - it is reinsurance. In the event of a breakdown of one for the duration of the repair, you can use the second lock;
• locks need to be chosen with different designs. It is recommended to install a lever and cylinder lock.

You should choose a lock only from reliable manufacturers. They guarantee high quality and reliability of models.

Hinges and platbands

For urban conditions or private houses, it is enough to install 2-3 loops. They must be supplemented with ball bearings. This increases their service life. Elements can be hidden and external, which are attached to the rack and canvas by welding. External loops spoil the appearance of the product, besides, they can be easily cut off. Hidden ones are much safer. However, they have their drawbacks:

1. the price of the door increases;
2. hinges are hidden in special grooves, this reduces the opening of the structure;
3. smaller opening angle.

The hinges are closed with a casing, it makes it difficult to break the door.

Design

The main choice is the design of the canvas. Finishing should be practical, resistant to mechanical damage and weather conditions. This is especially important for private houses and cottages. Anti-vandal powder coating meets these requirements.

The inner canvas should harmoniously fit into. Manufacturers offer designs with removable inner panels that can be changed if necessary.

How to choose the right front door to the apartment

Many manufacturers are engaged in the manufacture of structures. How not to get confused and choose the best steel entrance doors to an apartment in the price-quality ratio? We have compiled several rules with which it will be easy to navigate in this market segment:

2. Finishing can be done in MDF, powder coating, wood.
3. When choosing, you should know in which direction the canvas will open and the location of the handle.
4. Criteria for moisture and.
5. You should pay attention to what materials the heat and sound insulation is made of.
6. Complementing the design with locks, the degree of burglary resistance.
7. Door fittings:, hinges, chains must be of good quality, otherwise they will quickly fail.
8. When choosing a product, it is important to choose a model of well-known manufacturers. They will provide a long warranty period not only for the canvas, but also for accessories.
9. Installation should be entrusted only to professionals.

Additional functions of entrance doors

A high-quality door must not only meet the requirements of reliability and safety, but also perform additional functions. For city apartments, it is important that third-party sounds and smells from the entrance do not penetrate into the room. Therefore, you should pay attention to these parameters.

Metal entrance doors to the apartment with sound insulation

Noise and heat insulation of the front door is carried out with mineral wool, polyurethane foam or expanded polystyrene. In addition, they will protect the room from external sounds. According to professionals, the construction filled with polyurethane foam is considered the best. In addition, to ensure sound insulation, it is necessary to maintain a hermetic fit of the canvas to the frame. To do this, you need to install 2 contours of sealing gum around the perimeter of the frame. You can, if necessary, check with the seller as an additional metal front door in the apartment.

Another important parameter is the thickness of the door. It must be at least 60 ml, then the product will meet all the required characteristics.

Entrance metal doors to the apartment with a mirror

Entrance door designers have developed a completely new model with a mirrored canvas. In addition to the fact that it is convenient to have a full-length mirror, it does not take up space and visually increases the space. Such products can be divided into several types:

• with mirror panel, which is attached with a special adhesive composition;
• with built-in mirror– the mirror surface partially covers the panel.

This should be known! The only drawback of the designs is the inability to install a peephole. If necessary, a video peephole can serve as an alternative.
