The choice of the entrance metal door to the apartment. Choosing an entrance door to an apartment: the main criteria for choosing a metal door, professional advice Entrance doors what they should be

Entrance doors are an element of protection of the living space, and also complement the interior of the housing inside. There are many options for such designs, differing in the level of functionality, appearance and other parameters. Therefore, the selection and installation of entrance doors require knowledge of their features and characteristics.

Criteria for choosing entrance doors for an apartment

The quality of the front door determines the comfort of the living space, the level of protection from noise from the outside and the provision of thermal insulation of the apartment. Therefore, the choice of product is carried out taking into account several basic criteria. This allows you to choose a high-quality door that will last for decades and will not lose its performance characteristics.

Manufacturers produce many models of entrance doors with a variety of characteristics, so after spending some time, you can choose the product that you need

Since the door to the apartment performs a protective function, it must be made of high quality materials. If the cost of a door is suspiciously low compared to the average market price of products with the same characteristics, you should not choose it. Cheap models may be without insulation, with poor build quality, or with other shortcomings that will show up during operation.

The design of the front door requires a solid frame, good heat and sound insulation, as well as the possibility of precise installation of high-quality fittings.

The device of a high-quality front door assumes the presence of durable elements and a multilayer structure using heat and sound insulating materials. This design is characteristic of both wooden and metal products.

When choosing, consider criteria such as:

Types of doors and their features

Manufacturers produce a variety of door options for apartments, which differ in functionality, appearance, characteristics and cost. Knowing the features of each type of entrance door, taking into account the required level of sound and heat insulation and penetration protection, helps to make the right choice.

Many manufacturers specialize in the manufacture of one type of entrance doors, for example, only from metal or wood. Therefore, it is better to first determine the acceptable web material, and then select a product with the desired characteristics and design.

metal entrance doors

Models of metal entrance doors are in demand for installation in an apartment. They have a multilayer structure, which includes an outer metal sheet, stiffeners, a sound and heat insulator, and an inner lining. Lock, handle, hinges, anti-removable pins complete the design. The leaf with the box during installation is equipped with sealing tapes that run along the perimeter of the box and prevent the door from knocking during movement, as well as the penetration of cold air.

Metal doors must have a solid frame and an outer leaf with a thickness of at least 2 mm

A good door leaf should be made of metal with a thickness of at least 2-3 mm. In many models, the inner side of the leaf is made of a less durable material, since it does not provide much protection, because to open the door it is enough to cope with the outer sheet. The thickness is easy to check by pressing on the metal, which should not sag.

Stiffening ribs increase the stability of the structure against torsional forces. The longitudinal, transverse or combined arrangement of these elements prevents intruders from entering the premises.

Wooden doors for an apartment

Wooden doors can also be installed in apartments, which are also presented in a wide variety. They have inserts in the form of panels or glass. The latter option is rare, since glass elements reduce the thermal insulation ability of the canvas and its protective properties.

Wooden doors look solid and beautiful and provide a high degree of protection against intrusion.

For the manufacture of entrance structures, oak, pine or ash wood is used. The material is treated with an antiseptic, subjected to grinding and staining. Subject to manufacturing technology, strong, beautiful and durable canvases are obtained.

Soundproof doors

To achieve a high degree of sound insulation, the front door leaf is adjusted so that it fits especially tightly against the frame. Cloths have a multilayer structure, including soundproofing material, which is often used as foam. It is light weight and absorbs noise well.

Good soundproofing qualities of the door can be achieved by a tight fit of the leaf to the jamb, the presence of special materials in the leaf and the device of a vestibule in front of the entrance to the apartment

In metal doors, soundproofing material is placed between the stiffeners. A universal option is mineral wool, which absorbs noise and prevents heat loss. Sometimes a vibration filter and splen are used, which provide sufficient protection and are suitable for entrance doors.

Anti-vandal entrance doors

Anti-vandal doors have the maximum degree of protection against burglary, which especially makes sense to install in apartments located in the entrance without a combination lock. If the entrance to the building is equipped with a reliable locking device, then anti-vandal structures may not be used, since the entrance is well protected from intruders.

The main feature of this version of the canvases is that they have a reinforced lining, and the thickness of the steel sheets is more than 2.5 mm. The design is complemented by hidden hinges, a reinforced door frame, armor plates in the places where the lock and handle are located. The final protection component is anti-removable type canopies that prevent the door from breaking.

Doors with a reinforced structure are designed for installation in rooms located in poorly protected entrances.

Externally, the anti-vandal door practically does not differ from the usual one, and on the outside there may be a coating of laminated plastic, high-strength film or powder paint. These options withstand mechanical stress and prevent scratches.

Entrance doors with MDF trim

Metal sheets on the outside should have a durable layer, and on the side of the room, the aesthetic finish of the doors is more important. For this purpose, MDF panels are often used, which are sheets with a thickness of 8 mm or more, covered with a laminated film that imitates the structure of natural wood. Such panels are made from thin wood shavings mixed with adhesive and water-repellent components. As a result of hot pressing, plates are formed that are durable, affordable and practical.

In order to make the door aesthetic from the side of the room, you can pick up an MDF panel with any pattern.

Between the outer sheet of metal and the MDF panel there are layers of insulation and stiffeners. Thus, the panel performs not only a decorative function, but also provides additional sound insulation.

Entrance door with a mirror

From the side of the room, the door can be finished with panels, upholstery with soft materials or some other coatings, but a mirror made of durable glass looks especially impressive here. This door design is practical and looks original. The reflective surface can be small or the size of the entire door.

A small mirror on the front door allows you to abandon other mirror elements in the hallway

The mirror is placed in the middle with a distance of about 10 cm from the edges of the canvas. Such intervals allow you to install a lock and a handle without the risk of damaging the glass. It is worth considering that doors with a mirror are often made of metal, and a reflective insert is mounted in an MDF or wood panel.

Fireproof door models

Metal structures, in the manufacture of which fire-resistant materials were used, are called fire-resistant. Such products prevent the penetration of fire from the entrance, delaying the spread of flames. The door block does not deform when exposed to high temperatures, and the leaf materials do not emit acrid smoke.

Fire doors are made of special materials that do not support combustion and do not emit harmful substances at high temperatures.

The design of the door is tight and does not let the flame through for a period of 15 minutes to 6 hours. Such products are convenient in old houses, during the construction of which a lot of wooden elements were used.

Table: pros and cons of different types of doors

Dimensions of entrance doors for an apartment

An important role in the choice of products is played by the dimensions of the front door. There are models with standard parameters that provide convenient operation, safety and practicality of structures. GOST and SNiP regulate the performance of both doors and openings. For example, for a panel house, the optimal opening height is 1950–1980 mm, and the width is 740–760 mm. For a brick building, these parameters are within the following limits: width - from 880 to 930 mm, height - from 2050 to 2100 mm.

The main parameter of the door is the width, since the ease of use depends on it.

According to GOST 24698–81, the standard height of metal entrance doors must be at least 2–2.3 m, and the width can be from 800 to 1800 mm. If the opening has a width of more than 1.2 m, then it is necessary to install double-leaf structures consisting of two canvases, the width of which must obey certain rules:

The opening in an apartment building often has standard dimensions. Any redevelopment or change in the geometry of the opening is coordinated with the relevant authorities. At the same time, doors can be made according to an individual project.

Features of installing the front door to the apartment

To mount the entrance structure, you need to align the opening, which must have the correct geometric shape and neat edges. This will ensure easy alignment of the box and proper fixation of the canvas.

screwdriver;
drill;
building level;
foam gun;
roulette.

To align the box, you will need wedges and spacers 1.5 - 2 cm high, as well as self-tapping screws and anchor bolts that will allow you to fix the structure.

The front door leaf is hung on the box, which must be perfectly aligned in the doorway.

The installation of the entrance door must be carried out in accordance with the installation technology and taking into account the features of the type of construction. If the installation is carried out independently, then you need to perform the following steps.

A box is placed in the prepared opening, installing it from below on spacers, and fixing it with wedges on the sides and top. These elements help to align the structure. The quality of alignment in all planes is checked by the building level.
Wedges and spacers help to fix the box exactly vertically and horizontally
The canvas is hung on loops, check the absence of tension and deformation. If there are such defects, then the door is removed from the hinges, and the position of the box is corrected. The box is fixed in the opening with the help of lugs or holes in its structure. Anchor bolts with a length of at least 12 cm are installed so that their heads are recessed inward.
After leveling the door frame, it is fixed with anchor bolts so that their heads completely go into special hidden holes.
After that, the canvas is again hung on the loops, the evenness is checked and the position of the loops is corrected. The lock, handle and peephole are mounted in advance. A rubber seal is attached around the perimeter of the box to prevent slamming, and a closer is also installed. The gaps between the box and the wall are filled with mounting foam.
The door must be hung so that it closes tightly and presses against the jamb, and the anti-burglary elements go entirely into the reciprocal sockets in the box

How to repair a door

The front door is exposed to temperature changes, humidity and dirt, frequent opening / closing. As a result, the canvas is damaged and various breakdowns occur, for the elimination of which you need to know the repair technology.

The set of tools for repairing breakdowns depends on the type of defect. Screwdriver, rubber seal, tape measure and level are the main elements. Mounting foam and a cylinder gun may be needed to remove or adjust the door frame if necessary.

If distortions of the door frame appear, it must be released from the fasteners and leveled by installing linings in the right places

During the operation of the structure, the following breakdowns may occur that require repair:

a broken door handle or lock must be replaced. To do this, you need to purchase new products with the same characteristics and dimensions as the old ones. Broken parts are removed, and new ones are fixed in their place;
scratches on a wooden door can be eliminated with furniture wax, special corrective markers. With these means, the damaged area is treated, and the excess is removed with a napkin;
if the hinges are damaged, they must be replaced. In the event that the door sags, tighten the hinge bolts, controlling the position of the leaf with a level;
if cold air passes through the cracks, then the rubber seal must be replaced. A new tape is laid along the perimeter of the box in the area of adherence of the canvas.

Types of finishing the door to the apartment

Wooden canvases do not require special finishing, but are always painted or coated with a layer of protective varnish. This prevents deformation of the product and protects it from contamination.

The wooden parts of the doors must be covered with a layer of varnish to protect the wood from damage and dirt.

The current version of the door trim is leatherette upholstery. This is acceptable for older structures that are strong but have lost their appearance. For finishing, you will need leatherette of the desired color, foam rubber sheets about 5 cm thick, special nails with a wide hat, a ruler and a knife. Upholstery should be done as follows.

Doing a major overhaul of their homes, many owners are thinking about installing a new front door. Almost all front doors are now made of metal. Therefore, in order to choose a quality design for your apartment, you need to understand a little about the technical characteristics and installation process of iron doors. How to choose and install an iron door, you can learn from our article.

Steel door

The main purpose of the front door is to protect your home from illegal entry. Therefore, for greater security, you should opt for massive metal doors made of thick sheet steel, with reliable locks already embedded. Pay special attention to the hinges, they must be protected from cutting.

metal door construction

There are three types of metal entrance doors made of sheet steel:

DS 1 - with one protective sheet on three stiffeners. The disadvantage is the lack of sound and heat insulation, so you need to install a second door. The price of products with class DS 1 is about 10,000 rubles.
DS 2 - has two protective sheets on three stiffeners. It is also equipped with three special locks that will not allow you to remove it from the hinges, even if you cut them out. When attempting to access the transom system, the door will be blocked by an automatically closing beam. The price for such models is about 20,000 rubles.
DS 3 - sheets are attached to four stiffeners and has crossbar protection systems on the side and top. Also DS 3 contains a system of protection against drilling of the lock. The most reliable degree of protection will cost about 35,000 rubles.

Metal doors are not subject to mandatory certification. But if the manufacturer is confident in the quality of their products, they must comply with the requirements of GOST 31173-2003 “Steel door blocks. Specifications” and have a corresponding certificate.

Heat and sound insulation of a metal door

In addition to the strength of the door, another important factor is its heat and noise insulation. After all, if every sound from the entrance is clearly audible in the apartment, and in winter it blows cold from the door, then living in such conditions is at least not comfortable. Therefore, when buying an iron door, purchase models already insulated by the manufacturer and equipped with rubber seals. Consider the price factor, the cheaper the metal door, the less the manufacturer paid attention to its heat and sound insulation. Trying to save money at the expense of a low price, you can increase the cost of subsequent insulation.

metal door design

The next thing to pay attention to is the type of exterior and interior door trim. The range of design of iron doors is large, from the usual powder paint, to non-standard finishes with patterns or laminate sheathing.
Remember that a beautiful design is not always an indicator of quality, and sometimes vice versa, behind a beautiful design, manufacturers try to hide the low technical characteristics of the door.

Manufacturers of metal doors

On our market there are metal entrance doors of both domestic and foreign manufacturers:

Chinese metal doors

- Chinese doors are the cheapest, but when buying them, you should pay increased attention to the quality of the material from which they are made. Among Chinese iron doors, it is quite possible to find models acceptable for operation, the main thing is to take into account the thickness of the sheet iron and check the quality of the fittings.

European metal doors

- The products of leading foreign manufacturers are not cheap, but the quality of their workmanship is on top. Thick steel, a high degree of protection, a pleasant appearance and reliable fittings are worth the money. Most often there are iron doors of the Italian brands “Fbs”, “Dierre”, “Di.Bi”, which rely on the design of their products. There are also Israeli doors under the brands "Pandoor" and "Mul-t-Lock", which offer high quality doors with reliable locks.

Russian metal doors

A good option is the Russian-made entrance doors of premium class: “Senator”, “Pro-Tek”. Pleased with reliable locks, the possibility of quick warranty service, vandal-resistant coating and adapted design. If you look for cheaper door options, then in the segment from 12 to 25 thousand rubles. there are many domestic manufacturers. Among them, we single out such firms as: “Le Grand”, “Torex”, “Condor”, “Guardian”, “Guardian”. Due to high competition, the quality of service for Russian companies is constantly growing, so their products can become the golden mean between price and quality.

Standard sizes of metal doors

When buying an iron door, it is important to measure the doorway correctly. In old houses, the doors are installed in a wooden box, which must be removed, so the width of the opening will increase after dismantling.

It is better to entrust the measurements of the opening to an experienced person, since one cannot make a mistake in this matter. It is better to choose the largest possible size for your opening so that there are no problems with bulky items.
There were times when the entrance doors were installed with a width of only 70 cm! According to SNiP 21-01-97, this violates the fire safety technique, since the front door is an emergency exit.

Many people prefer to make a door to order, as they want to increase the opening. In addition, bespoke items have better locks that can be changed, a wide choice of finishes and good thick metal.

Below are the standard sizes of entrance doors for apartments and houses:

860x2030 mm;
880x2050 mm;
900x2100 mm;
950x2100 mm;
1000x2100 mm and above.

Installation of a metal door

Having bought an iron door, it is important to install it correctly. If you do not have experience in this type of work, then it is better to contact professionals. Moreover, many door-to-door stores provide this service as a bonus upon purchase. So that you can control the installation process, read the main stages of door installation:

Dismantling the old door - at this stage, the old canvas is removed from the hinges, the trim and the door frame are removed, the doorway is cleaned from the remnants of the solution or the assembly exchange.
Installing a new door in the opening - the box is level, set in the correct position and temporarily fixed with wooden wedges.
The final fastening of the frame in the opening - depending on the model of the door, the frame can be mounted on anchor bolts or metal pins. Some models have additional fasteners in the form of metal strips that are fixed to the wall with dowels. Be sure to check that the installers have secured the box to all available fasteners.
Filling the gaps with foam - at the end of the installation, the space between the box and the opening is filled with mounting foam. The drying period of the foam can be from five hours to a day.
Processing slopes - after drying, the excess foam is cut off with a knife and the slopes of the doorway are made.

Types of locks for a metal door

There are times when the owners are not satisfied with the locks installed in the door and they want to replace them with more reliable ones. In such cases, it is necessary to buy a new lock, but before doing this, check out the main types of door locks for metal doors:

Level lock

- Level lock - the design of this type of lock is one of the first invented by man, despite this, level locks are considered one of the most reliable. The principle of operation of the lever lock is quite simple. Its mechanism consists of plates - levers, which, when opened, line up in a certain combination on the key. If the combination does not match, it is impossible to open such a lock. Lever locks for metal doors are produced by brands: Barrier, Guardian, Elbor, Kale, Cisa, Mottura, Mul-T-Lock.

Combination lock

- A combination lock is a combination of two or three types of locks in one mechanism. Combination locks have a high cost, but justify the price due to their increased reliability. Produce combined locks for metal doors brands: "Guardian", "Barrier", "Elbor", "Kale", "Cisa", "Mottura", "Mul-T-Lock", "Vachette", "Asix", "Iseo ".

cylinder lock

Cylinder locks - the main advantage of cylinder locks is the ease of repair and replacement of the lock. It is enough to replace the central secret mechanism - the “larva” cylinder. The principle of operation of a cylinder lock is quite simple and consists in lining up the pins inside the cylinder in a certain combination. Such locks are produced for metal doors “Kale”, “Cisa”, “Mottura”, “Mul-T-Lock”, “Vachette”, “Asix” , Iseo.

Remember that no matter what type of lock you choose, installing it on a metal door requires certain skills and special tools. Therefore, if you are not confident in your abilities, entrust the work to specialists.

You won’t be able to save on buying a quality door, so it’s better to save up for a reliable option than to buy the cheapest one. It is important to take measurements carefully, and if necessary, increase the size of the opening to a safety standard.

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 door to order directly from the manufacturer, where you can specify and write down all the 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.

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.

The theater begins with a hanger, and the house begins with the front door. The TAM.BY team launches a new special project "Door reception". In it, we will tell you how entrance doors are made, tell you which models are highly durable and reliable, and explain how to properly care for one or another of their types.

Let's start by figuring out how to choose a quality front door. Alexander Petrovich, Deputy Development Director of the Steel Line company, the No. 1 manufacturer of entrance metal doors*, helped us with this.

The first factor to consider when choosing an entrance structure is where it will be installed. Doors for an apartment and a house differ significantly in technical characteristics. They have different requirements and are produced using different technologies.

How to choose an entrance door for an apartment?

A high-quality apartment door should have the following characteristics:

— reliable sound insulation: you should not hear how the elevator opens or the neighbors in the entrance are talking;

— burglary resistance: the door must be strong so that it cannot be opened;

— tightness: a tightly closing door will protect you from a cold draft, as well as smells from the entrance;

— durability: it is important that the locks work properly, the coating of the handles is not erased, the finish is not damaged, and that the door closes softly and quietly all the time you use it;

— modern design: the front door is one of the elements of the interior, so it should be in harmony with the decoration, furniture, interior doors.

Each of these parameters is influenced by various factors that must be considered when choosing an entrance door.

Noise isolation

The sound insulation index for an apartment door must be at least 32 dB. This indicator is influenced by the thickness of the MDF panels, the number of sealing contours, the accuracy of the construction and the type of filler.

Metal transmits sounds much better than MDF. Therefore, panels should be installed on both sides of the door. The minimum thickness of MDF, which will provide good sound insulation, is 10 mm. But 16 mm thick panels cope even better with this task.

The more sealing contours on the inlet structure, the more reliably it protects against extraneous sounds. A quality door should have at least two of them. But even ten sealing circuits will not provide proper sound insulation if there are gaps between the door leaf and the frame. Therefore, be sure to pay attention to the accuracy of the manufacture of the structure.

As for the filler, the best option is mineral wool. Its thickness must be at least 50 mm. It is necessary to remember one feature of this material: from vibration, mineral wool settles over time and lets noise through. To avoid this, the filler must be fixed along the entire height of the door leaf.

Burglary resistance

Burglary resistance determines the reliability of the input structure. It is influenced by various characteristics of the door leaf, box, locks.

The first step is to evaluate the thickness of the steel: the optimal indicator ranges from 1.0-1.5 mm. Structures assembled using the spot welding method are stronger than those made using manual arc welding. The seams in the latter are fragile and over time the door can be deformed. But the most reliable structures are made using bending technology. This means that the canvas and the box are made from a single sheet of steel, bending it using high-precision equipment. The more bends, the stronger the geometry of the structure. The principle of automobile crash tests applies here: the more stiffening ribs a car body has, the more reliable it is.

Resistance to burglary also depends on the accuracy of manufacturing the input structure. If there are gaps in it, the attacker will be able to get to the edge of the canvas with a crowbar and bend it.

It is important that the door is equipped with anti-cuts and steel plates in the lock area. You also need a mortise armor plate for a cylinder lock. Unlike the consignment note, the mortise armor plate is installed in the body of the lock, so it cannot be knocked down.

Also pay attention to the burglary resistance class of locks: it must be at least the third. Locks of the fourth class are even more reliable. Products of Russian, Turkish and Italian production have proven themselves best. It is worth buying locks from trusted brands that have been on the market for a long time.

tightness

If the door is sealed, it will reliably protect against drafts and odors from the entrance. The manufacturing accuracy of the input structure largely determines its tightness: the smaller the gaps, the better. You also need a durable seal that does not wrinkle over time and does not require complex maintenance.

Pay attention to the tightness of the door leaf to the box. It is best to purchase designs with a porch regulator. Thanks to him, you can adjust the tightness of the door leaf and be sure that the door closes hermetically during the entire period of operation.

It is important that there is an overlay with spring-loaded curtains on the lever lock. When closed, they close the hole for the lock and do not let air out of the entrance, which cannot be said about curtains without springs.

Durability

The service life of the input structure largely depends on the quality of the loops. If something has happened to the locks or the handle, they are easy to replace. But if the hinges fail, you will have to buy a new door.

In order for the hinges to serve as long as possible, they need to be periodically lubricated. It is inconvenient to remove a heavy door leaf every time, so it is better if special holes for lubrication are provided on the hinges.

The design of the loops is also important. Over time, the house shrinks, which can change the geometry of the opening. In this case, the hinges on the support bearing work unevenly and quickly grind off. Hinges with a steel sphere at the base are considered much more reliable. They self-center and continue to work evenly in any position.

The door to the apartment should not rust. A high quality polymer coating is responsible for this. Before buying, pay attention to whether there are inclusions, hairs, crumbs and other changes on the surface. If you find them, you have a short-lived coating in front of you. Most likely, the door was painted by hand in violation of technology. The first signs of rust will appear on the canvas within a year.

How to choose the front door for the house?

The door of the house, unlike the apartment door, goes directly to the street, and not to the entrance. Therefore, the entrance structure must provide good thermal insulation. It should not freeze and pass cold air even at very low temperatures.

Another important characteristic is weather resistance. The door of the house is operated in different climatic conditions: it is affected by the sun's rays, frost, rain and snow. Therefore, the entrance structure must be made of weather-resistant materials.

steel door

The main advantage of a steel door is a high level of burglary resistance. Other characteristics vary depending on the quality of the input structure.

When choosing a steel door for your home, pay attention to the sealing system. Mineral wool is not suitable for outdoor structures, as it absorbs moisture and loses its heat-shielding properties. It is important that the door has a thermal break: this will protect it from freezing.

Before buying a door, check with the seller if there is a layer of insulation between the stiffeners of the door leaf and the interior trim. If it is not there, then the canvas will freeze through the ribs. Ice forms in places where metal parts protruding into the house (they are called moldings) come into contact with the outer sheet of steel.

Remember that no matter how good a door is in terms of thermal insulation, it will not perform its function if it is not installed correctly. For any outdoor structure, "warm installation" must be carried out.

In order for the door not to rust at high humidity outside, it must undergo a special anti-corrosion treatment. The threshold and joints of the box elements are considered the most vulnerable zones: it is in them that corrosion begins. The first rusty smudges can be seen already six months or a year after the installation of the door.

Choose doors whose vulnerable parts are treated with a zinc-containing solution. Even more reliable designs are made of galvanized or stainless steel. They are not afraid of atmospheric influences.

Door panels should be made of heat and moisture resistant MDF. This coating has a greenish tint. It is treated with a special composition and resistant to moisture.

aluminum doors

Aluminum doors and galvanized steel doors are durable and strong options for home and office. Such structures are not afraid of changes in temperature and humidity, are fireproof, are not subject to corrosion and distortions, and provide a high level of sound insulation. Also, aluminum doors retain heat well, but they must have a thermal break.

The advantages of aluminum door structures include the fact that they do not require complex maintenance. It is enough to lubricate locks, hinges and other moving parts with machine oil or grease once every six months.

Aluminum entrance doors have only one significant drawback - their high cost. In addition, they are inferior to steel structures in terms of burglary resistance.

PVC doors

Plastic entrance structures are rarely installed in residential buildings. They are more suitable for office and industrial premises. Nevertheless, PVC entrance structures provide good heat and sound insulation. In addition, they are resistant to any weather conditions.

Plastic doors are characterized by low burglary resistance, so it is not recommended to install them in the house. In addition, a small variety of finishes is unlikely to allow you to choose an option that fits perfectly into the interior.

Wooden doors

Entrance doors made of natural wood are suitable for those who love classics and elegance. But this is far from the most practical option for the home.

Wooden doors are environmentally friendly and beautiful. In addition, unlike metal, wood is not afraid of corrosion. However, natural wood doors have a number of disadvantages. They have poor fire resistance properties. But the problem can be solved by processing the door leaf with special tools. Another disadvantage of wooden doors is instability to external influences.

Due to fluctuations in humidity and temperature, the door leaf may swell or, conversely, shrink. And this means that the structure will not close well. In addition, temperature and humidity affect the coating of a wooden door: it can crack and wear out. If these defects are not eliminated in time, moisture can get on the wooden sheet and cause it to rot.

Competent care of a wooden door will help to avoid many problems. Remember that wooden doors do not tolerate changes in temperature and humidity, so you should not put heaters, humidifiers, air conditioners next to them.

If the coating of a wooden door is severely worn or scratched, it should be completely renewed. But it is better to entrust this work to professionals.

“Steel Line” has been making entrance doors for more than 20 years. We are known at 14 corners of the world. We control the high quality of our dzvyarey and with soul we put ourselves and the skin at the stage of creation.

*on the contest "Choice of the Year"

Metal doors are used to equip apartments, houses. Such products have high strength, wear resistance, are not susceptible to moisture and retain heat well.

When choosing models, pay attention to the security system and technical reliability.

How to choose a metal door

The basis of a metal door is made of aluminum or steel. Steel structures are more durable, provide high-quality noise and heat insulation.

Aluminum sheets are lightweight, so they are easy to install. This material allows you to realize many options for finishing.

Pay attention to the way the door opens. It is better to choose designs that open on both the left and right sides. External or internal doors to choose - depends on taste preferences.
Consider the technical characteristics of the model, because it will be constantly under mechanical and thermal influence. To keep the look longer, opt for powder coating or oak paneling.
The level of noise and heat insulation are important criteria. As a rule, a metal door is insulated with mineral wool, polystyrene foam, corrugated cardboard.

Mineral wool is best suited for internal filling of the product, it is an environmentally friendly material with high thermal insulation properties. Other materials are cheaper, but can crumble quickly.

The door must have a reliable system of protection against intrusion. Locks of 1-4 classes of burglary resistance are built into metal structures that are used for domestic purposes.

By type, locks are divided into lever locks with increased secrecy and cylinder locks, which are subject to recoding in case of loss of keys. As a rule, modern models are equipped with these two locks.

Pay attention to the quality of accessories. It includes door hinges, handles, chains, eyes, and other decorating elements. The aesthetics and beauty of these details also testify to the reliability of accessories.

Notice the door hinges. Do not buy products that are equipped with less than three hinges. Consider the opening angle of the structure: 90, 120, 180 degrees. The higher this figure, the better.
It is better if the model is made from a single-curved profile.
When choosing a door, specify the thickness of the door leaf. The minimum figure is 40 mm, but the structure will not be protected.

The thicker the canvas, the more reliable the protection and the higher the thermal insulation characteristics. In severe winters and constant frost, the best option would be a thickness of 80-90 mm.

Pay attention to the thickness of the sheet, the optimal indicator is 2-3 mm. Do not purchase products with a steel thickness of less than 0.5 mm, such designs are prone to dents and have a short service life.

The thickness of the door frame must be twice as large to withstand the fastening of the fittings.

The most vulnerable places of the door leaf must be sealed with stiffeners. This improves the performance of the product, reduces the risk of deformation.
Pay attention to whether the product is equipped with an armor plate, this is a mandatory component of the kit.
Choose models with ball hinges and anti-cuts that are attached from the side of the hinges.
The tightness of the structure is ensured by a double-circuit seal, which protects against the ingress of foreign odors, drafts and retains heat well.
The diameter of the locking bolts must be at least 16-18 mm.

The design and decoration of the door depends on your preferences. A popular finish option is plastic panels, which are durable and impact resistant.

With the help of polymer coloring, the structure acquires a new color and protective characteristics. Lacquering is a type of coating with a high level of resistance. Wood trim is the most environmentally friendly and effective way to decorate.

When choosing a color, be guided by your taste, but keep in mind that dark canvases will retain their presentation longer.
It is desirable that all fittings are made by one manufacturer.
The presence of a manganese plate will prevent the door from being drilled.
