My home is my castle. Noticeable for a long time and not by us, but for sure. And what fortress can be without strong gate? An illiterately chosen and installed door will not be able to serve as a reliable obstacle for intruders. The most correct choice today is to install in the apartment of the entrance metal door.

It will keep the property and calm of the owner in any situations and will serve for many years. Metal entrance doors to the apartment will adequately represent the face of the owners, if the choice of design, the type of finishing and accessories correspond to modern ideas about the entrance door. The range today is so great that the question is which better to put.

Requirements for iron doors and burglary-resistance classes

The choice is always associated with compliance with some criteria. To understand what is more suitable in each case, you need to decide on the main tasks. Modern requirements for the input metal doors formulate in a nutshell difficult. The main ones are the following:

• High hack resistance.
• A high level of access control.
• High quality heat and noise insulation.
• Presentable appearance and at the same time ease of use and care.
• Long warranty service and service.

The main requirement for the entrance door is a high class of reliability. That is, resistance to hacking.

There are four class hack resistance of the door:

• First. The doors are so slight, which is wedged with a simple tool. This is an economy class and you can choose it, but not for home or apartment. The most vivid representatives of this class are products of Chinese manufacturers.
• Second. Such designs are able to withstand the pressure of mechanical tools, but it will easily give up an ordinary drill. Such is also better not to put in the apartment. You can choose for a cottage, a small cottage or garage.
• The third. This design is wedged exclusively with heavy duty power tools in the hands of a specialist. Such specialists recommend choose for installation in an apartment or private house.

• Fourth. The designs of this class are called armored, as they can withstand a rifle shot. These are the best doors, but they are the most expensive.

Metal door design elements

The best, reliable metal entrance doors in the apartment, which you want to choose, are distinguished by the complexity of the design and quality of manufacture. In general, any design is a set of following elements:

• Door box. This is the basis of the structure. It keeps a canvas on it, it is she opposed to the main attempts of hackers when trying to penetrate the protected room.
• Door leaf. This structural element performs anti-burglar and aesthetic function. Thieves are often trying to cut holes in it, so the canvas should be durable. From the quality of the canvas finishing to a greater extent, the appearance of the door.
• Lock. This same constipation that prevents unauthorized penetration during intellectual hacking. It should be easy to use, strong and durable. What you need, decide for yourself.
• Loops. The quality of the web and its functionality is dependent on them, and sometimes burglary resistance of the block as a whole.
• Platbands. These items not only decorated, but also protect from access to the way between the wall and the box.
• Heat and sound insulation and seals. Thanks to these elements in the house, warm and cozy, no noise, no extraneous smells hear.
• Eye or video intercom. These optical devices provide remote control over the entrance door.

The best products are equipped with a mass of additional devices, including the shelters, anti-burglar pins, etc.

Material of manufacture

Cold rolled and stainless steel - ideal materials for the manufacture of metal doors. The canvas should not have unnecessary seams. Correctly choose from a solid sheet. Frames of door blocks from all-bent elements are considered the most reliable.

As for the thickness of the metal, the best representatives can boast the thickness of the canvas from 2 to 4 mm, between the two sheets that the ribs are mounted. What they are more, the better. You can choose with at least three, one of which is installed vertically, and two are horizontally. More reliable products have a third sheet of canvas, mounted between two main. At the same time, the ribs of stiffness are between each layer. If there are increased security requirements, it is better to choose such a door.

Pipes or corner from which the box is performed must have a metal thickness of at least 3-4 mm. You can, of course, choose the metal thicker, but such a product will weigh too much.

The best loops and canopies are made of particularly durable varieties of steel, and hinges and bearings are used in their designs. The loops are two types:

• External.
• Hidden.

Access to hidden is difficult, so they cannot be cut. It is recommended to make a choice in favor of the door with such. The outer loops are not protected, except for the strength of the material from which they are made. The number of canopies is limited only by the construction weight. If the door weighs more than 70 kg, then three or more are used, and usually - 2-3 pieces.

For fixing the canvas in the case of spillation loops apply anti-burglar pins. The time required for hacking the door depends on their thickness and material. You need to choose the most durable and durable.

Locks

According to statistics, if the thieves spent 15 minutes on the door lock and could not operate it, they leave. Locks differ in type, installation method and reliability. Immediately, we note the entrance door to the apartment is recommended to protect at least two locking devices. The choice depends on the possibilities of the wallet, as the price variation is very large.

The following types of locks are installed on the input metal doors:

• Suwald. These are the most reliable and best in terms of burglar resistance. The latter quality of such products depends on the number of Suwald. If there are no more than six, to open the lock is impossible for a simple launder. There are devices with 10 plates. Recommended for use as the main locks. The only drawback is large sizes. The choice is made taking into account the thickness of the canvas.
• Cylinder. These mechanisms provide a high level of protection against intelligent hacking, but are recommended for use as minor or additional.
• Smartlocks or electronic locks. These devices are characterized by high functionality and burglar resistance, but poorly prevent opening mechanically. In addition, they require constant nutrition. Used as additional doors protection measures.

The market has a wide selection of suvald and cylinder locks with the possibility of transcoding. When the key loss does not have to buy a new castle. A special key reprograms the lock under the second set of keys.

By type of installation, the locks differ on:

• Overhead. Installed directly from above on tight. In this regard, they do not possess great reliability. It is often used on second doors. The choice in favor of these is done if there are no options for the sch.
• Curling. Embed into the canvas. Provide maximum strength and reliability of the shut-off design.

There are models with battle systems separated around the perimeter of the canvas. These are the best and common types for entrance doors.

Sound and thermal insulation

The best input metal doors should ensure a decrease in heat loss and penetration of foreign noise in the apartment. In order to improve the quality of its products, manufacturers use insulation and seals.

The following materials are used as the heat insulator:

• Mineral wool. Material has good heat and sound insulation properties. Does not rot and absolutely harmless to humans. The best products are insulated with basalt wool.
• Polyurethan. This material in its properties is better than the first. Fully eliminates the appearance of the drum effect. Absolutely environmentalized and does not absorb moisture.

Special attention is paid to the seal and its installation. Sealing ribbons are installed in the focus on the door canvase and the box. This is done in such a way as to eliminate the occurrence of even the smallest slots, often caused noise and heat leakage.

The sealer can be from different material - silicone, plastic or rubber. Rubber is the best choice, because it retains its properties longer. For greater efficiency, the seal is glued and on the front and on the back of the canvas.

On heat and sound insulation, as well as the appearance strongly affects the quality of the finish.

Exterior finish

Most often for this use the following materials:

• Massif of natural tree. Wood has a low thermal conductivity, so it is good to keep warm.

And she looks gorgeous. But it is very expensive. This is today exclusive.

• MDF panels. The material is little inferior to the tree in its heat insulating qualities, and in appearance too. It is significantly less and used more often.
• Laminate. PVC film significantly reduces heat loss, but compete with a tree or MDF is not in a state. Such coating has inexpensive doors.

On video, you can familiarize yourself with the rules for choosing an iron entrance door:

• Leather. Today it is rare. As an insulation, an ordinary wool or foam rubber is stuffed under artificial skin. They quickly filled with moisture and rot.
• Powder coating. This is an anti-vandal coating. Wheel insulator from paint no. Today, the coatings are very popular with hammers and enamels that imitate silk coating.

Buy the entrance door is recommended directly from the manufacturer, that is, in the corporate store. Before going to the store, you should decide on the purpose and main functions of the door. First of all, it is necessary to determine the budget. Then remove the size of the box. Directly from communicating with the seller, find out the advantages and disadvantages of a particular model, and also familiarize yourself with the passport of the product. All data on materials and their quality should be reflected there.

No matter how convincingly not promoted manufacturers of wooden entrance doors their products, it is out of doubt about strength and reliability significantly inferior to steel counterparts. However, among the metal fellow, there is a gradation that shares them into categories in the degrees of protection, in terms of impeccable service and for aesthetic qualities. Steel entrance block - the acquisition is not discharge of cheap purchases. Therefore, before going to the store, you need to find out how to choose an inlet metal door, for which you need to pay, and what is not worth spending.

In priority choice reliability

We will not deceive yourself and others, proving that the "iron" defense we like in the aesthetic indicators. Although the latest Italian, and domestic models can be called attractive without reservations. We are solved on the installation of a steel "barrier", first of all, due to ultrahigh physico-mechanical characteristics of the material and due to the possibility to equip the design with the maximum number of protective devices.

First you need to pay attention to:

• on the technical characteristics of the product specified in the manufacturer's documentation;
• on the design features of the frame and the linen of the entrance door;
• by the number of mounted devices capable of complicating the solution to the problem of unauthorized penetration.

Moreover, for myself, you personally need to determine the necessary and sufficient limit of reliability in advance, since the bust in these indicators entails not only the increase in the price. Often, super reliable metal doors create absolutely unnecessary problems to the owners. It will be irrevocably breaking too complex crab locks with an overnight rigel jam, after which it comes to a trite to install a new door. Too serious canvas is difficult to open / close the children and elderly family members. In addition, the mechanisms are rapidly wear out, the frame is deformed, the canvas sails on the exterior loops.

Required and sufficient technical specifications

Let's start with the quality and thickness of the metal, on which the weight of the structure is dependent and the price. In the production of iron entrance doors does not use "Iron". It is not used in pure form anywhere, only alloys. Make sheet steel doors obtained during hot or cold rolling. Once we find out how to choose a metal door, you need to compare the properties of the material:

• The hot-rolled metal is suicide and dark on the color, but under the decorative coating of its blacks is not visible. He is more susceptible to the appearance of rust foci on its surface, quickly eats corrosion. If the manufacturer used exactly this type of material, the document will include GOST for the 19903 number.
• Cold rolled alloy is more expensive than the previous version. Without processing pleases with standard color galvanized steel. The doors made from it are not affected by direct contact with atmospheric troubles. GOST with a number of 19904 will tell about its use in the manufacture of the door.

If the alloy is oversaturated with carbon, it loses plasticity. High content of alloying elements is also nothing. Optimal for the production of doors and their further operation are sub-associated (up to 11%) and medium-carbon (up to 0.6%) steel alloys.

Next, we estimate the prospects and choose the iron door, designed to protect our property on the thickness of the steel sheet. This indicator will also find in technical documents. Its values \u200b\u200bmay vary from 0.8 mm to 4.0 mm, according to:

• the doors made of sheet steel with a thickness of 0.8-1.0 mm do not belong to the clan of the input structures. Suitable for the arrangement of economic buildings intended for storing low-value things, gardening inventory;
• the canvas of two sheets with a metal thickness of 1.0-2.0 mm is a suitable solution for equipping office space in a multi-storey business center with security;
• 2.0-2.5 mm - the norm for the door leading from the apartment in the entrance;
• 4.0 mm is the optimal option for a country mansion, especially if it does not live in it.

The thicker sheet steel, the harder and more expensive the door. It will be more expensive not only due to the cost of the material, but also due to the special installation scheme, additional powerful loops and the enhanced frame. The optimal weight of the iron door for residential facilities is considered to be 70 kg. 90-100 kg and more weighing doors for banks and bulletproof options.

Structural features of the steel door

The two main components of any door block are a canvas and a box, it is a frame that more corresponds to the product from steel blanks. The most reliable is recognized as a monolithic frame with one welded stitch, a less reliable frame, welded from four segments of the hot-rolled co-rolled pipe rod. The most "hip" type is welded from four segments, each of which in turn is welded from two equal to the length of the corners.

If shorter: the more welding seams, the worse, according to the statement of engineers. In their opinion, welding changes the initial settlement geometry. The consequences of the violation of the estimated geometric parameters can not appear at all immediately after installation, among them:

• dry and accompanying the need for application effort;
• right opposite drafts and gaps that allow you to cut the inner loop, open the door scrap or mount;
• enclosure of the canvas, the bolts of the lock system.

On the front side of the canvas should not be welded seams. The outer part must be made of the monolithic sheet, otherwise it will not withstand a strong impact of a pitchflower.

Canvas as a landmark

The canvas itself is a rectangular frame, which is attached to two metal sheets. There may be one steel outer leaf and an inner panel of array, MDF or a chipboard coated with laminated film, veneer, cheap vinyl. This feature distinguishes the entrance blocks to the capable of withstanding the attacks of the atmosphere and are not able to resist the solar rays and moisturizing.

If the owner decides which of metal doors to choose to install in the opening, communicating with the street, the answer is unequivocal - completely iron, since the temperature differences and fluctuations in the level of moisture will lead wood and materials created from its fibers. We are equipped with blocks with tandem metal-MDF apartments or an extra entrance to a country house, leading from a closed tambour in housing.

Note. The condition of full protection against hacking with infertility thieves - lomik and vague is steel cash and focus. They will close all unreliable sections and stop access to responsible details.

Recalculate the ribs of stiffness

Between the outer steel sheet and the inner panel, it does not matter from what material it is made, the ribs of cruelty are located. At a minimum there should be two vertical and one horizontal. Best of all, if the ribs are larger than the specified limit, because their number increases reliability. But simultaneously with reliability they will increase weight.

In order to reduce the weight of the ribs, they do not perform from a conventional corner or a rectangular steel pipe, but from long rolled steel with a complex profile. Bend complicated-profile ribs is almost impossible, and they are driving the door slightly.

Reliable door hinges

Those who wish to find out how to choose the right door to choose, attention should also be paid on loop. Steel door blocks equip two varieties:

• hidden loops, unconditionally eliminating the desire to cut off;
• common outdoor, cut which in principle can, but remove the canvas will not allow anti-mounted devices - small steel pins, "recessed" into special holes of the frame with a closed door.

For inexplicable reasons, the last type is most often used. Apparently because the degree of protection provide anti-conversations.

The amount of loops determines the weight of the canvas. For a standard in 70 kg, there are enough two loops if the door is not operated with increased intensity with a closing 50 times a day. Those who are going to actively move back and forth, and those who decided to install a bullet-proof door, loops will need 3-4 pieces. The loops must have a reference bearing, which will extend the term of impeccable devices and facilitates operation.

About warm and ways to save it

The metal door does not contribute to the preservation of heat, as the material perfectly conducts heat waves. The thermal insulation is placed between the outer and inner sheet of the web, for which the mineral wool insulation or foamed polystyrene is used because of the resistance of the combustion and environmental priorities. You should not hope for insulation, cold bridges are still formed in the zone of the ribs of rigidity and the perimeter of the frame. But with isolation is still warmer than quite without it.

From drafts and foreign smells will save the rubber seal. Most manufacturers equip the canvas with two rows, but experts believe that one is enough.

Castle - friend and faithful watchdog

"Invertible guard dogs", that is, not opened locks does not exist. The difference between the unreliable and reliable lock is only in a segment of the time that the attacker needs to be spent on an opening. True, too complex stopping systems are sometimes summoned by the owners themselves, because neither manufacturers nor the sellers of iron doors are not advised to get involved in constructive delights.

The most efficient shut-off option, both consumers and manufacturers recognize the presence of two castle systems of different types. It is desirable that the main one is equipped with bars for locking in several directions for a long time, and the auxiliary satisfied the owners often closing the door to the short period.

To talk about what entrance doors are beautiful and what it is better to choose to arrange a house or apartment with a prevailing interior and exterior, no washed. Opinions in all individual, there is no need to bring them to the general denominator. You can only advise to buy door blocks with an external anti-vandal coating that protects the appearance of the input group from fans to spoil beautiful things. Its, by the way, can be applied independently after installation. So, on the top of the search cliffs, we will strengthen the checkbox with the inscription "Reliability", measure the discharge according to the rules that can be found in the appropriate article, and rust to conquer sellers awareness, not forgetting that we came to buy a super durable iron barrier.

The selection of the entrance door is a fairly responsible moment, since the preservation of the entire property of the house or apartment will depend on its design, and sometimes the life of the owners will depend on its design. Today, the range of specialized stores forms many manufacturers representing their products, which has a wide range of prices - from the most modest to very high. Therefore, you can always choose such a door that will fully comply with the possibilities of housing owners.

The purpose of the entrance door is not only the protection of housing from intruders, as it should prevent the penetration of external noise and cold air. In addition, there are models capable of creating a reliable barrier even intense flame during a fire. How to choose an inlet metal door advice professionals - they are defined depending on where it will be installed: at the entrance to the apartment or in a private house, as well as taking into account the many criteria that directly affect operational qualities and this design.

Criteria for selecting the entrance door

To clarify all the nuances, we turned to the Moscow manufacturer of the entrance doors "Profmaster", where more than 80% of orders are individual production "to order", Since it is possible to choose the door without compromise in quality.

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

• Place installation. The door can be installed on the street in a private house or at the entrance to the apartment, that is, in the indoor entrance, protected from the immediate external influence. From this will depend on the selection of insulation material and external sheaving.
• Protection level. To this criterion, several aspects can be attributed at once:

- metal thickness used for the manufacture of the door;

- frame design;

- the amount of metal layers in the door canvas;

- the number of rigid rigidity inside the frame frame;

- the number and design of locks and loops;

- The presence of an overview element.

• Insulation material. In order for the door to do not let the cold masses and extraneous noise, it is insulated with mineral wool, foam, polyurethane foam or cardboard. In some cheap models, insulation may be absent at all.
• Number of seals. They can be installed on the door leaf or box, in one, two or even three rows. For fire structures, sealing contours from special materials are used.
• Weight weight. The quality product should be severe, as it has reliable stiffeners and made of high-quality, fairly thick metal sheet.
• The designer solution that harmoniously drives the door to the overall design of the facade, if the door is installed in a private house.
• Fire quality materials, if you plan to purchase a door having protection against flame proliferation.
• The anti-trimmed coating is especially necessary if there are animals in the house, which can scratch the door facing, or in the apartment, where there is no code lock at the entrance to the entrance.
• The door must have a quality certificate or a passport on the product where all its characteristics will be indicated.

Evaluation of the main characteristics of the doors

The price of such products is high enough, but it is possible to be confident in the safety that they will fully provide. Therefore, recently, more and more residents of apartments and house owners give preference to this particular door variant.

So, the design of the entrance doors must fully respond to all the criteria for safety and comfort when it opening and closing, as well as satisfy the owners of housing in terms of its design. Therefore, making a choice, you need to make a list of requirements for yourself in advance, and if the model responds to them, then this option is ideal for a particular entry into the building or apartment.

For many owners of an urban apartment or country house, the right choice of the metal entrance door is considered to be the right question. In this article, let's talk about how to choose the design under consideration, we learn what reason and decoration can be, as well as insulation and fittings of the product.

What to pay attention to when choosing

During the hike to the store to purchase the entrance door, you must pay attention to the following details:

• Protective design functions. The product must be protected from hacking thieves. In this regard, the door should differ in high indicators of reliability and strength.
• Duration of operation. The more the product will serve, the better for the consumer. It should be noted that some manufacturers give a one-year warranty on their goods.
• Door filler material. The thermal conductivity and soundproofing design indicators depends on its properties.
• Choosing outdoor doors, many consumers pay special attention to the appearance of the goods, but this selection criterion is not always correct. Materials should not be present in the doorway fabric. In addition, the door should not creak during operation.

Another nuance of the selection of the design under consideration is considered to be a choice of country to the manufacturer. As you know, in the domestic construction market there are not only Russian, but also Chinese models, as well as goods received from Europe. Each of them has its advantages and disadvantages.

So the products produced in China differ in comparative cheap, but they do not differ in good protective qualities. European goods cost much more expensive from domestic counterparts, but such doors are manufactured in accordance with European standards. That is why the door canvas does not always fit into our movements, so the most optimal option will be the choice of the domestic model.

And now you will get acquainted with the advice of experts on the selection of steel entrance doors in the apartment:

• For lack of drafts, it is better to choose a tubular type insulation, and not the products made in the form of a W symbol, as in the refrigerator and other household appliances;
• The door canvas close from two sides with metal bent with welded or solid sheets with a thickness of at least 1.5 millimeters;
• Inside the design requires a set of several ribbiness to increase the strength of the product. In total, the door is provided from 2 to 5 transverse edges.
• Entrance doors must have at least two locks, which will increase the protective functions of the product, will prevent the penetration of thieves in the apartment;

• To prevent bending of the band, the molding is set, made in the form of a symbol T;
• Standard door loops usually serve up to 7 years. For a smooth stroke of the design during opening and closing, loops are used on bearings. Hidden products do not allow to remove the input structures even after the dispensing of the loops, but such results need to be achieved only after installing the anti-low pins.
• A better finishing option is considered to be a surface with applied powder paint, which is characterized by high resistance to different atmospheric influences.

Base Door and Frame

The frame of the entrance door consists of a metal closed P-shaped profile. On the frame of the product under consideration using point welding, sheet steel of a certain thickness is fixed. In order to enhance the design, ribbon ribs are used. High-quality products have two ribs vertically, three more - in the horizontal direction. Depending on the location of the lock, the average rigidity element may have a monolithic structure or separated into two independent parts on the locking area.

In the construction market you can find a huge number of types of door frames. Products from the profile pipe, metal corner or bent to a certain shape of a steel sheet are considered the most popular options for manufacturing such a design. According to experts, the best material for obtaining a high-quality and reliable basis is the use of a profile pipe with a wall thickness from 3 to 5 millimeters.

Buy boxes made of curved sheet or corner, is not recommended, since such elements are bending and twisting during operation. At the same time, the base of the profile pipe has improved stability and convenience in the installation. Such a detail is well fixed in the walls of the wall even with their own hands, without the help of specialists.

If we talk about the bases of the curved sheet, then such products have good indicators of heat and sound insulation, but they have limited strength compared to the analogs from the profile pipe. The thickness of the door leaf is set to the width of the frame. So for apartments, this parameter must correspond to a size of 50-70 millimeters.

If the entrance door is installed in a country house, then the thickness of the base may increase to 100 millimeters. Such an increase in parameters contributes to improving reliability and safety, as well as heat and soundproofing product quality. The enlarged mass will make the canvas more attendant, so the skeleton selection is better to exercise in favor of standard options.

Insulation

The instended doors protect the apartment or a private house from drafts and foreign sounds that are coming from the entrance or street, prevent the heat outlet. How to insulate the metal entrance door are asked by many of the owners of real estate, because each such material has its strengths and weaknesses. Next, we describe the most popular types of door structures insulation.

To begin with, consider the foam. Sheets of such thermal insulation material have good insulating indicators, do not absorb moisture, and also do not succumb to deformations. The polyneolster has negative qualities, this is the possibility of penetration of cold through educated gaps, as well as a low degree of fire safety.

Such products are well suited for the insulation of the door leaf installed in the apartment. If the input structure is installed in a country house, the foam is not suitable as the insulation through the possibility of freezing. To eliminate the problem, the formed clearances between the labored sheets are poured by mounting foam.

The second type of the insulation of the foam rubber has good insulating and soundproofing indicators. The main disadvantage of the material under consideration is the possibility of disrupting the structure during operation. In this regard, the foam rubber is not recommended for installation at the entrance doors of country buildings.

Another popular product for insulation of the designs under consideration is the mineral wool. These products enroll in construction stores in the form of rolls or mats. For insulation, the door is better to use the last variant, as the slab thermal insulation is characterized by improved strength indicators. The material under consideration is not amenable to burning, has a small cost. The main minus of mineral wool is the possibility of absorbing moisture, so before laying such products need careful waterproofing.

Door hinges

The details under consideration are used to mount the door leaf to the frame. With the help of the door loops, they can perform their basic functions, open and closed, but when choosing these elements, you must pay attention to their type and use. Let's deal with this question in more detail.

For mounting input groups, the following types of loops can be used:

1. Universal. Such products differ from the analogues with an increased period of operation, make it possible to open the web in both directions (left and right). Universal loops are not removed during the movement of large-sized furniture, to remove the door you must completely unscrew such a product.
2. Removable or disconnect loops are considered easier in operation. With their help, you can remove the canvas even without unscrewing.
3. The screw loops allow you to open the door to any side, they are used to operate structures with protrusions in the end part.
4. Bar loops make it possible to open outward and inside at the same time, with the possibility of 180 degrees can be rotated. Such elements are reliably disguised in the opening, they are regulated in three points.

When choosing loops, special attention must be paid to the quality of the goods. You should only trust proven manufacturers. Dimensions of the product have special importance. So the height of 7.5 centimeters is used for the input groups weighing 10 ... 25 kilograms. For standard entrance doors weighing 25-40 kilograms you need to pick up loops of at least 10 centimeters in height.

Outer and interior doors

The designs under consideration may have different types of external and interior decoration. It depends on the personal preferences of the customer, the stylistics of the living room and the neighboring rooms, the design options for the facade of the building. For many models, internal and external finishes differ, although in some cases the surface of the products is performed in the same color range.

The most popular finishes are considered:

• painting;
• using laminated fiberboard on the inside of the door;
• powder spraying on the surface;
• lining.

The main requirement for external decoration is the resistance to aggressive factors. In this regard, even a cheap Chinese product should look an armored or bulletproof. If two entrance doors are installed on the box, then the inner design is preferably made wooden.

To finish the inner surface of the web, wood products are most often used, such as veneer, array or lining. In some cases, the frame can be covered with laminated Fiberboard slabs. The factory entrance door usually has a painted metal surface from both sides.

Furnitura

When choosing doors for the home, you must pay special attention to the fittings of the product (locks and handles). In the modern market there is a huge number of models and types of locks, which differ in each other by means of locking (cylinder or suburb), as well as the installation method. The latest models should be divided into mounted, mortise and internal.

Picking up the castle, try to acquire more expensive products, since cheap analogues are unlikely to underline the thief. In the modern market, there are mainly Chinese products, although a really high-quality product can be purchased from a Ukrainian or domestic producer. In addition, the good performance indicators have European goods.

Door handles can be stationary or pressure. So the latest models lock the input design using a simple press. Such models will not protect the house from possible hacking. In this regard, it is necessary to install stationary handles away from the location of the lock.

Seals

Such small but important parts of the entrance door as seals are used to prevent the penetration of the drafts in the middle of the room. Such elements protect the house from outsided sounds and heat output, contribute to a more dense fit of the canvas to the frame. In practice, several different insulation are used, then we describe the most common varieties.

Rubber products have a different cross-section profile. The fact is that the door canvas can have a certain form of the groove, under which it is necessary to select the sealing gasket. Rubber seals are characterized by high rates of durability and strength, a small cost.

The most secure for a person from the point of view of ecology is the sealing agents on silicone basis. Such materials are recommended to establish on the doors of children's institutions and educational institutions. Another positive quality of the silicone sealer is considered an acceptable cost.

Major seals can be considered as comfortable. These products appeared on the modern construction market relatively recently, but already aroused increased interest among consumers. Magnets are introduced into the structure of the elastic base, they improve the degree of fitting of the door leaf to the frame due to the links between the substance and the metal.

Features of fire doors

By design, fire doors differ slightly from ordinary entrance groups. Such products can be sliding, folding and sliding. This design includes special products that impede the combustion process. In addition to improved properties on the obstruction of the ignition, DP have good frost resistance and explosive indicators, they are also considered shock-resistant and wired.

Finishing the surface of the door design is processed by special powder paint. The main element here is considered metal sheets, thickness from 2 millimeters. Mineral wool is used as the heat insulator. Polystyrene foam, foam or cellular cardboard for fire-resistant doors are not suitable.

An integral part of the design under consideration is considered a threshold that provides protection of rooms from exposure to smoke and carbon monoxide arising during a fire prevents the penetration of drafts and insects. For glass fire doors, automatic thresholds are used, since they cannot be mounted in the design of the product. Another mandatory element of such a door is the automatic closer.

Making the overhaul of its housing, many owners think about installing a new entrance door. Almost all entrance doors are now made from metal. Therefore, to choose a high-quality design to your apartment, you need to understand a little in the technical characteristics and the installation process of iron doors. How to choose and install the iron door, you can learn from our article.

Steel door

The main purpose of the entrance door is the protection of your home from illegal penetration. Therefore, for greater security, it is worth stopping your choice on massive metal doors from thick sheet steel, with already embedded reliable locks. Pay special attention to the loop, they must be protected from spill.

Metal door design
