How to choose entrance doors to the 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 secure your apartment from intruders with additional actions: carry out, arm the apartment and install. These are additional costs that can be avoided. However, there are nuances that affect reliability. It is heat and burglary 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 make the right decision.
The first thing you should pay attention to is the material used to make the doors. Wood or metal is most often used in production. Let's look at the features of each. High-quality wooden entrance doors to an apartment are expensive. They are quite reliable, and it is precisely such products that create prestige for their owners. Not every wood is suitable for making a high-quality structure. Better to use:
Products made from other types of wood are significantly inferior in strength and operational characteristics. In this case, it is better to purchase doors made of metal. Price category different. We will tell you further how not to get confused and know what to look for when choosing.
The front door must meet two criteria - reliability and security. Therefore, when choosing, it is important to consider the thickness of the base and outer sheet. It is important that the structure has stiffening ribs. It would seem that the higher these parameters, the better. Excess weight will lead to wear on the hinges due to rapid inertia when opening.
Let's consider the main characteristics of metal entrance doors to an apartment in more detail.
Not every metal is suitable for entrance doors. Medium-carbon and medium-alloy alloys are considered optimal. You can check the sheet thickness in the technical data sheet, but you should know the basic classification:
The optimal weight of the product should be within 70 kg. Structures weighing about 100 kg are installed in cans.
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 lead to wooden panel into disrepair.
It is mandatory to install steel casing and vestibules that will hide all areas and protect the premises from unauthorized entry.
Stiffening ribs are installed between the sheets. The minimum set is 2 vertical and 1 horizontal. As their number increases, the reliability and weight of the structure increases.
When selecting a product, it must meet the following criteria:
You should choose a lock only from reliable manufacturers. They guarantee high quality and reliability of the models.
For urban conditions or private houses, installing 2-3 loops is enough. They must be supplemented with ball bearings. This increases their service life. Elements can be hidden or external, which are attached to the stand and canvas by welding. External hinges spoil appearance products, and they can be easily cut. Hidden ones are much more reliable. However, they have their drawbacks:
The hinges are closed with a platband, which makes it difficult to break the door.
The main thing when choosing is the design of the canvas. The finish must be practical, resistant to mechanical damage and weather conditions. This is especially important for private houses and cottages. Vandal-proof powder coating meets these requirements.
The inner fabric should fit harmoniously into. Manufacturers offer designs with removable internal panels that can be changed if necessary.
Many manufacturers are engaged in the manufacture of structures. How not to get confused and choose the best steel entrance doors for an apartment in terms of price-quality ratio? We have compiled several rules that will make it easy to navigate this market segment:
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 outside sounds and smells from the entrance do not penetrate into the room. Therefore, you should pay attention to these parameters.
Sound and heat insulation of the entrance door is made with mineral wool, polyurethane foam or polystyrene foam. In addition, they will protect the room from external sounds. According to professionals, the best design is one filled with polyurethane foam. In addition, to ensure sound insulation, it is necessary to maintain a tight seal between the canvas and the frame. To do this you need to install 2 circuits sealing gum along the perimeter of the frame. You can, if necessary, check with the seller about how to add an additional metal entrance door to the apartment.
Another important parameter– door thickness. It must be at least 60 ml, then the product will meet all the required characteristics.
Entrance door designers have developed a completely new model with a mirror panel. 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:
You should know this! The only drawback of the designs is the inability to install a peephole. If necessary, a video peephole can serve as an alternative.
You cannot skimp on the safety of your home. The entrance door must fully meet all requirements modern life. To better navigate the models, we have compiled a rating the best manufacturers 2017-2018 in different price segments.
The products first entered the market more than 17 years ago. In addition to manufacturing steel entrance doors to apartments, they produce locks. The products are in great demand due to their high quality and reasonable price.
The manufacturer offers 3 types of designs:
All models have hidden hinges, which increases their safety.
Advice! If you need to remove elements, you should contact the manufacturer directly or a service center.
As proof of the above, here is a consumer review of Forpost products.
xumuk032 Russia, Bryansk, door “Forpost” 228: Advantages: durable coating, good insulation, looks decent.
Disadvantages: the keys to different locks are almost the same in shape and color.
This is a steel door with a metal thickness of 1.5 mm on the outside. The inside is also metal, but a little thinner. Filling: polyurethane foam. And also a bunch of locks.
The outer side is made of steel 1.5 mm thick with weather-resistant coating. That is, this one is suitable for installation directly on the street. The interior of the canvas and the box is coated with polymer. Which is also very successful, because... when installed between the street and a heated room, there will be condensation, and polymer coating is not harmful, unlike MDF....

The history of the Elbor manufacturer begins in the 70s of the last century. The following series of doors are currently produced:
High quality sets the product apart from the market of similar products.
The manufacturer first began production in 1994. Products are different high cost, which is not surprising. It has received the highest awards for quality and durability. Products have a certificate fire safety. Currently, the market offers products of different designs in a wide price range, but if funds allow, you should choose the premium class. On the manufacturer's website you can see photos of entrance doors in different price ranges.
This manufacturer produces doors in good value"price-quality". Mineral wool is used for thermal insulation. The design is resistant to external influences, the canvas is painted with a special varnish composition. Doors can be installed. No obvious shortcomings were identified, and therefore it is worth paying attention to the product when choosing.
Metal doors from the manufacturer "Stal" are similar to those produced by the Elbor plant. The only difference is model range. The manufacturer does not produce premium models; the main production is designed for the average consumer. The products are made from sheets with a sheet thickness of 2 mm, a profile is used complex design, which increases the strength of the doors.
Choosing an entrance door to an apartment is not an easy task and raises many questions. You need to know what qualities a design should have and what to look for when choosing. The front door is the keeper of the hearth, preventing noise, cold and uninvited guests from entering the home. It should also look presentable, as it acts as the calling card of the apartment.
Any premises, residential or industrial, greet the visitor with the front door. Choosing an internal opening door for an apartment is not difficult now. However, manufacturers offer a wide selection of products, the differences between which are in materials, dimensions, colors and styles.
Many people are unable to make an informed choice due to the wide variety. This is especially true for those who buy entrance doors to an apartment for the first time. To avoid errors, you should take into account the requirements for any input structures:
Before you go to the store to buy, you need to consider other points:
On construction market There is a wide range of entrance structures; they also produce designer canvases and technical models. They are classified depending on the material used in their manufacture.
This is the most popular type. Manufactured using special technology from durable materials. There are models that are additionally coated with an anti-corrosion compound, which allows the blades to be used in different climatic conditions, extending their service life.
The thickness of the metal sheets also matters: for European entrance doors it is 1 mm, for Chinese ones - from 0.5 to 1 mm, for domestic ones - from 1.5 to 3 mm. The strength characteristics of the entrance structure depend on the thickness of the metal. European models have standardized sizes, while our manufacturers also produce non-classical options.
The customer can choose the design and format of insulation.
Before choosing a metal door for your apartment, you need to familiarize yourself with the classification by level of complexity:
The following finishing materials are used: thermal film, polymer or powder paint, plastic or wooden lining, vinyl leather, auto enamel, varnish, MDF overlays and other materials.
Important! In order for the selected metal entrance door to successfully perform its functions, it is important to install it correctly.
Not long ago, wood was used as the main material for the production of entrance structures. Now the user has a choice, where each product differs in its performance properties. However, wooden panels are considered 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, and as a result they last longer.
Wooden products are no longer as popular as before, this is due to the fact that there is a large selection on the market artificial materials. But some customers prefer natural massif tree. Considering design features, we can distinguish three types of wooden entrance doors:
What materials are wooden entrance doors made from:
Wooden doors to apartments are preferred by those customers who prefer environmental friendliness and a natural appearance.
This type is gradually gaining popularity. Many customers prefer just such entrance doors to their apartments, explaining their choice by the small size of the hallway. Nowadays a mirror can be mounted in both wooden and metal products.
An entrance door with a mirror looks organically in any interior, often acting as a key decorative element. The design is interesting for its decorative effect, but can also perform other functions:
Important! To ensure the desired effect, you must carefully choose the shape and size of the mirror you install. This will highlight the style of the apartment and decorate the interior.
The mirrors themselves are practical products. Indeed, in a small hallway it is sometimes difficult to place a separate large mirror. But the door panels are just the right size.
Standard dimensions are determined by GOST standards, regardless of the material of construction. The main parameters are as follows:
Important! For entrance structures standard size more than for interior ones. This is done so that a person carrying a load can freely pass through the opening.
The most common are metal structures. Most often, a steel door to an apartment is chosen, which provides adequate protection for the home. There are both global and domestic manufacturers on the market producing products different styles and sizes.
Metal has long been used to make entrance doors to apartments. This is the most durable material that provides protection against burglary. For this reason, it is popular for both residential and production premises. When choosing an iron door for an apartment, you should pay attention to the base material. The following metals are used to make products:
When choosing a product for your apartment, pay attention to the thickness of the base layer - the more, the better design will protect housing. Only two materials are used as a base, but the products differ from each other due to the decorative layer. Used as decoration:
To increase the mechanical characteristics of the entrance door to an apartment, manufacturers equip products with stiffeners. These elements provide protection against deformation and increase burglary resistance. The more stiffening ribs, the more stable the structure will be. It is worth understanding that due to an increase in the number of these elements, the weight increases, which means that the hinges will experience increased loads and fail faster.
When choosing a color you need to consider general style home decoration, color of flooring material, walls, main furniture. Correct tips to help you choose the color of the entrance door to your apartment:
Important! These tips are suitable both for choosing the entrance panel to the apartment and for interior partitions.
The most popular designs are from the following brands:
This is not a complete list of companies manufacturing entrance doors for apartments.
In this matter, there is a main requirement - in case emergency the design should not create obstacles during the evacuation of people. If we consider practical side, then take several points into account:
In the case of apartment buildings, the following points are also taken into account:
For the most part, where the canvas will open is the decision of the apartment owner.
Choosing an entrance door to an apartment is not a problem, since there are many offers: metal, wooden crafts or designs with mirrors. The main thing is that the door provides adequate protection for the apartment and at the same time matches the interior of the room. You can take into account the rating of the entrance metal doors to the apartment, but it is equally important to install the door correctly.
A metal entrance door is undoubtedly necessary for modern apartment and at home. Its main function is protection from uninvited guests. The first thing a guest or visitor to an institution may notice is the iron door. Its quality indicates a serious approach to home improvement and imparts solidity to the organization. Its function is also to prevent the release of heat from the room in winter and to maintain coolness inside the building in summer.
Manufacturers vying with each other to talk about a wide range of metal products, so it will not be easy for an inexperienced buyer to choose a metal door. However, it is doubtful that a cheap product will be of excellent quality. The costs of developing the design and manufacturing the product from high-quality metal alloys affect the price, and a strong, reliable input block will not be cheap. This is the main reason why the buyer devotes a lot of time to the question of how to choose a metal entrance door.

Naturally, the protective function will be the main one. Which ones are better to choose? Constructive decisions, 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 heavy weight increases wear on the hinges and fastenings of the box.
You can find a wide variety of entrance doors on sale, how to choose best option? It is better to choose doors based on the required strength (leaf, locks, fastenings), aesthetics and how additional element insulation and sound insulation interior spaces. To decide which protection option will be optimal for a given case, let’s consider the main protection indicators.
Features of steel processing
Steel for door design can be processed in two ways, and the choice of method will greatly influence the final quality of the product. Looking at the documentation and certificates, you can see one of the values:
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 will tell you 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 valuables are not 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 may turn out to be very heavy and not very convenient to use.
Entrance doors are classified according to reliability classes. This is reported by GOST R 51072-97, which provides for 13 classes of entrance doors. Among them, designs 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:
It goes without saying that this applies 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 it most likely has not been tested, and the quality may be questionable.
The quality of metal entrance doors is greatly influenced by the number of stiffeners. These are metal elements that are under outer sheet and are installed to enhance protection. The best entrance structures will have more than two vertical and one horizontal stiffeners.
However, as their number increases, the weight of the entire block increases. In order to reduce weight, modern stiffeners have non-standard shape, which allows you to maintain the strength of the product and reduce the weight load on the hinges.
Entrance metal doors can have various options internal filling. Among them, several methods of making a frame are possible.
As you can see from this list, the first frame manufacturing option with the fewest welds is the best. With the appearance of each new weld, the structure may become skewed and change the originally conceived geometry. Putting a box with a minimum number of welds is the best option.
The door leaf is made of steel and has stiffening ribs and a frame inside. The side facing the home may have an additional layer of aesthetic material.
You need to choose a metal entrance door with knowledge of the features of the hinges. They, just like the canvas, will help protect the room from burglary. The design uses two types of loops:
Hidden hinges automatically eliminate the possibility of removing the sash and entering the apartment. External ones can be cut off, so entrance door hinges are additionally equipped with anti-removal devices: pins or tongues. Please note the presence of these devices in the selected design.
A standard blade weighing less than 70 kg is mounted on two loops. If you plan to frequently open and close the sash, or the leaf is over standard weight, you should take care of installing 3-4 loops. The supplied support bearing will help the hinges work for a long time and with high quality.
How to choose the right entrance door, taking into account the locks? The optimal option is one with two locks of different devices:
There are locks:
As a standard, two cylinder locks or one cylinder and one lever are installed in the entrance structure. An electronic lock can be installed additionally. It is worth considering some features that will help eliminate possible lock picking:
It's also worth remembering that cylinder locks do not tolerate mechanical shocks well.
Let's consider which metal doors And better retain heat inside and noise outside. The metal structure itself will not be able to create good thermal insulation, and manufacturers are concerned with creating insulation 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 sealant is laid in two areas where the door frame and leaf join in the closed door position.
The door peephole, which has already become traditional, should provide a wide overview, a clear and precise picture. In addition to the peephole, modern manufacturers make it possible to purchase doors with a built-in video peephole, from where the image is transferred directly to your home computer.
Aesthetics
Modern entrance doors are very different from their counterparts twenty or thirty years ago. If necessary, you can choose either a massive or an elegant option without sacrificing strength. The outer surface can be coated with paint, and the most best coatings For inner surface This:
A variety of colors and textures allow you to decorate the room as the owner wishes. The front door as simply a security guard for the premises 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 apartment building it might make sense to color it outer side sashes in color steel doors entrance so as not to attract unnecessary glances. It is also possible to apply anti-vandal spraying to the canvas, which will protect it from external damage.
Imported products stand apart: the designs are solid, but expensive, the price of products from Polish, Italian, and German manufacturers starts from 30 thousand rubles and ends in disappointing six-digit figures.

The products of large domestic manufacturers are not inferior in appearance to foreign ones, and please with decent quality and reasonable prices.
Choosing a high-quality and durable metal entrance door that will last for many years is a very important issue. It is worth dedicating some time to study the known information and the selection of local stores. The cost of a steel structure will be repaid by ease of use and good protection from uninvited guests.
My home is my castle. It was noticed a long time ago and not by us, but for sure. And what kind of fortress can there be without strong gates? Illiterately chosen and installed door will not be able to serve as a reliable barrier for intruders. The most correct choice today is to install a metal entrance door to your apartment.
It will preserve the property and peace of mind of the owner in any situation and will last for many years. Metal entrance doors to an apartment will adequately represent the face of the owners if the choice of design, type of finish and fittings correspond to modern ideas about the entrance door. The range today is so wide that the question is which one is better to buy.
The choice is always associated with compliance with some criteria. To understand which ones are more suitable in each case, you need to decide on the main tasks. It is difficult to formulate modern requirements for a metal entrance door in a nutshell. The main ones are the following:
The main requirement for an entrance door is a high reliability class. That is, resistance to hacking.
There are four door burglary resistance classes:
The best, reliable metal entrance doors to an apartment that you need to choose are distinguished by the complexity of their design and workmanship. In general, any design is a set of the following elements:
The best products are equipped with a lot of additional devices, including recesses, anti-burglary pins, etc.
Cold rolled and stainless steel — ideal materials for making a metal door. The fabric should not have unnecessary seams. Choose the right one from a single sheet. Frames of door blocks made from solid bent elements are considered the most reliable.
As for the thickness of the metal, the best representatives can boast of a sheet thickness of 2 to 4 mm, between two sheets of which stiffeners are mounted. The more there are, the better. You can choose from at least three, one of which is installed vertically, and two of which are installed horizontally. More reliable products have a third sheet of canvas mounted between the two main ones. In this case, there are stiffening ribs between each layer. If there are increased security requirements, it is better to choose such a door.
The pipes or angle from which the box is made must have a metal thickness of at least 3-4 mm. You can, of course, choose thicker metal, but such a product will weigh too much.
The best hinges and awnings are made from especially strong grades of steel, and their construction uses hinges and bearings. There are two types of loops:
Access to hidden ones is difficult, making it impossible to cut them off. It is recommended to choose a door with exactly these. External hinges are not protected by anything other than the strength of the material from which they are made. The number of canopies is limited only by the weight of the structure. If the door weighs more than 70 kg, then three or more are used, and usually 2-3 pieces.
Anti-burglary pins are used to secure the canvas in case of sawing off the loops. The time required to break open the door depends on their thickness and material. You need to choose the most durable and durable ones.
According to statistics, if thieves spent on door lock 15 minutes and they couldn’t open it, they leave. Locks differ in type, installation method and reliability. Let us immediately note that it is recommended to protect the entrance door to the apartment with at least two locking devices. The choice depends on the capabilities of the wallet, since the price range is very large.
The following types of locks are installed on metal entrance doors:
There is a wide selection of lever and cylinder locks on the market with the ability to recode. If you lose your key, you don't have to buy a new lock. A special key reprograms the lock for a second set of keys.
According to the type of installation, locks differ in:
There are models with crossbar systems spaced around the perimeter of the canvas. These are the best and most common types for entrance doors.
The best metal entrance doors should reduce heat loss and the penetration of extraneous noise into the apartment. In order to improve the quality of their products, manufacturers use insulation and sealants.
The following materials are used as a heat insulator:
Particular attention is paid to the seal and its installation. Sealing tapes are installed in the recesses on door leaf and box. This is done in such a way as to eliminate the occurrence of even the smallest cracks, which often cause noise and heat leakage.
The seal can be made from different material- silicone, plastic or rubber. Rubber - the best choice, since it retains its properties longer. For greater efficiency, the seal is glued to both the front and back of the canvas.
Thermal and sound insulation, as well as appearance, are greatly influenced by the quality of the finish.
Most often the following materials are used for this:
And she looks gorgeous. But it is very expensive. This is an exclusive today.
In the video you can familiarize yourself with the rules for choosing an iron entrance door:
It is recommended to buy an entrance door directly from the manufacturer, that is, in a company store. Before going to the store, you should decide on the purpose and main functions of the door. The first step is to determine the budget. Then take the dimensions of the box. Find out the advantages and disadvantages of a particular model directly from communication with the seller, and also familiarize yourself with the product data sheet. All data on materials and their quality must be reflected there.
No matter how convincingly the manufacturers of wooden entrance doors promote their products, they are undoubtedly significantly inferior in strength and reliability to their steel counterparts. However, even among their metal counterparts there is a gradation that divides them into categories according to degrees of protection, according to periods of impeccable service and according to aesthetic qualities. A steel entrance block is not a cheap purchase. Therefore, before you go to the store, you need to figure out how to choose a metal entrance door, what you need to pay extra for, and what you shouldn’t spend money on.
Let’s not deceive ourselves and those around us by proving that we like “iron” protection for aesthetic reasons. Although the latest Italian and domestic models can be called attractive without reservation. We decide to install a steel “barrier”, first of all, because of the ultra-high physical and mechanical characteristics of the material and because of the ability to equip the structure with the maximum number of protective devices.
First of all, you need to pay attention:
Moreover, for yourself personally, you need to determine in advance the necessary and sufficient limit of reliability, since going overboard in these indicators entails not only an increase in price. Often, super reliable metal doors create absolutely unnecessary problems for owners. Overly complex crab locks break irreparably with the top bolt jamming, after which you have to simply install a new door. A door that is too heavy is difficult to open/close for children and elderly family members. In addition, the mechanisms quickly wear out, the frame is deformed, and the canvas sags on worn out hinges.
Let's start with the quality and thickness of the metal, on which the weight of the structure and price depend. No iron is used in the production of iron entrance doors. It's generally in pure form not used anywhere, only alloys. Doors are made from sheet steel obtained through the process of hot or cold rolling. Since we are figuring out how to choose a metal door, we need to compare the properties of the material:
If an alloy is oversaturated with carbon, it loses its ductility. A high content of alloying elements is also useless. Medium-alloy (up to 11%) and medium-carbon (up to 0.6%) steel alloys are considered optimal for the production of doors and their further operation.
Next, we will evaluate the prospects and choose an iron door designed to protect our property based on the thickness of the steel sheet. We will also find this indicator in technical documents. Its values can vary from 0.8 mm to 4.0 mm, according to which:
The thicker the sheet steel, the heavier and more expensive door. It will cost more not only because of the cost of the material, but also due to the special installation scheme, additional powerful hinges and a reinforced frame. Optimal weight iron door for residential properties it is considered 70 kg. Doors for banks and bulletproof options weigh 90-100 kg or more.
The two main components of any door block are the leaf and the frame, also known as the frame, which is more consistent with a product made from steel blanks. The most reliable is a monolithic frame bent from a profile pipe with one weld; less reliable is a frame welded from four sections of hot-rolled profile pipe. The most “flimsy” type is welded from four sections, each of which in turn is welded from two corners of equal length.
In short: the more welds, the worse, according to engineers. In their opinion, welding changes the initial design geometry. The consequences of violating the calculated geometric parameters may not appear immediately after installation, including:
On front side The fabric should not have welded seams. The outer part must be made of a monolithic sheet, otherwise it will not withstand a strong blow from a heavy sledgehammer.
The canvas itself is a rectangular frame to which two metal sheets are attached. There may be one steel outer sheet and an inner panel made of solid wood, MDF or particle board covered with laminated film, veneer, or cheap vinyl leatherette. This feature differentiates the entrance blocks into those that can withstand atmospheric attacks and those that cannot resist sun rays and hydration.
If the owner decides which metal door to choose for installation in an opening connecting to the street, the answer is clear - completely iron, since temperature changes and fluctuations in moisture levels will render wood and materials created from its fibers unusable. They equip apartments with metal-MDF tandem blocks or an additional entrance to a country house leading from a closed vestibule to the housing.
Note. The condition for complete protection against burglary using simple thieves' methods - a crowbar and a crowbar - is steel cashing and ledges. They will close all unreliable areas and prevent access to critical parts.
Between the outer steel sheet and the inner panel, no matter what material it is made of, there are ribs of cruelty. At a minimum there should be two vertical and one horizontal. It is best if there are more ribs than the specified limit, because their number increases reliability. But at the same time as reliability they will increase weight.
In order to reduce weight, the ribs are not made from a regular corner or rectangular steel pipe, but from long products with a complex profile. It is almost impossible to bend the complex-profile ribs, and they add little weight to the door.
Those who want to know how to choose the right entrance door should also pay attention to the hinges. Steel door blocks equipped with two types:
For inexplicable reasons, the latter type is most often used. Apparently, because the degree of protection is provided by anti-removals.
The number of loops determines the weight of the fabric. For a standard of 70 kg, two hinges are sufficient if the door is not used with increased intensity with closing 50 times a day. Those who are going to actively move back and forth, and those who decide to install a bulletproof door, will need 3-4 hinges. The hinges must have a support bearing, which will extend the service life of the devices and facilitate operation.
A metal door does not help retain heat, since the material perfectly conducts heat waves. Thermal insulation is laid between the outer and inner sheets of the fabric, for which mineral wool insulation or foamed polystyrene is most often used due to its combustion resistance and environmental priorities. You should not rely on the presence of insulation; cold bridges still form in the area where the stiffeners are located and along the perimeter of the frame. But with insulation it is still warmer than without it at all.
A rubber seal will eliminate drafts and foreign odors. Most manufacturers equip their canvases with two rows, but experts believe that one is enough.
There are no “incorruptible guard dogs,” that is, locks that cannot be picked. The difference between an unreliable and a reliable lock is only the length of time that an attacker will need to spend on opening it. True, overly complex locking systems sometimes fail the owners themselves, which is why neither manufacturers nor sellers of iron doors advise getting carried away with design refinements.
The most effective locking option, both consumers and manufacturers recognize the presence of two locking systems different types. It is desirable that the main one be equipped with crossbars for locking in several directions for a long period of time, and the auxiliary one is suitable for owners who often close the door for a short period.
There is no point in discussing which entrance doors are more beautiful and which are better to choose for arranging a house or apartment with an established interior and exterior. Everyone has individual opinions, there is no need to reduce them to a common denominator. We can only advise you to buy door blocks with an external anti-vandal coating, which protects the appearance of the entrance area from those who like to spoil beautiful things. By the way, you can apply it yourself after installation. This means that at the top of the search rock, we will strengthen the flag with the inscription “reliability”, measure the opening according to the rules that can be found in the corresponding article, and rush to conquer the sellers with awareness, not forgetting that we came to buy a super strong iron barrier.
