Second entrance door to the apartment: how to install and why it is needed

Two doors in one frame

In most cases, in order to have a double design, there is no need to purchase a pair of canvases.
Most often, one of them is already present in the opening and is subsequently supplemented by a second one (as a rule, a wooden model “from the developer” becomes internal, and a reliable steel product provides external protection).

Advantages of double products

The two entrance doors to the apartment form a kind of vestibule, which becomes a serious obstacle to the path of cold air.

A pair of canvases reliably protects against extraneous noise.

If there is a danger of burglars entering, the second door will also provide additional protection.

Of course, all these statements are true provided there is a sufficient degree of reliability and tightness of each structure.

Installation and its features

If you want to install two entrance doors to an apartment, it is best to contact the services of a specialist who will assess the condition of the opening’s supporting structures and the possibility of installing both leaves on one frame.

Professionals call the use of one box the more preferable option, since it minimizes the likelihood of distortions and ensures maximum geometric coincidence of elements of a rather complex structure.

Before installing two panels, the jamb may need to be reinforced so that it can withstand the increased load.

The installation of a pair of metal sashes is excluded; one of them must be wooden.

Equipment and design of canvases

If there are two entrance doors in the apartment, the insulation layer is installed only on a metal sheet.

Sealing contours can be installed on both leaves.

First of all, attention is paid to the burglary resistance and secrecy of locks installed on a metal sheet, however, the presence of a high-quality locking device on the second part will in no case become an excess.

addition to an existing canvas (with installation on one, including an expanded, box, or combination of completely autonomous blocks),

installation of a combined pair of new sashes.

For this purpose, you can choose any product from the range of wooden structures and, for maximum protection, a model from the series of metal doors “Jaguar 13 K”, “Jaguar 22”, “Jaguar 23”, etc.

By entrusting measurements and installation to the company’s specialists, clients receive the highest quality of work and the opportunity to verify the exceptional performance of the products.

How to install sliding doors with your own hands: sequence of work

Having familiarized yourself a little with the design and operating principle of sliding doors, you can safely begin installing them.

But first, let’s clarify a few points regarding the choice of a sliding system.

• Firstly, this is the length of the guide - it should be slightly more than twice the width of the canvas that will be installed on it.
• Secondly, pay attention to the profile itself and the number of rollers in the mechanism - if we are talking about a single door, then there should be a pair of rollers, and if you plan to install double sliding doors, then two pairs of rollers should be included with the guide.

Now you can proceed to the actual installation. To better understand the essence of the issue, let’s consider the sequence of work point by point.

To begin with, we prepare the door leaf and first of all screw a couple of rollers to its upper end - there is no need to select any grooves for them. We just take and fasten them with self-tapping screws at a distance of 50-100mm from the edges of the canvas. The second stage of work associated with the preparation of this part of the sliding door is to cut handles into the door leaf and, if necessary, a latch of a special design.

To insert a handle, you will need to select grooves in the blade or simply drill or cut an oblong through hole with a jigsaw (if the edges of the handles you choose are rounded).

As for the lock, its insertion is carried out in exactly the same way as installation in swing doors - the difference lies only in the design of the lock itself. I completely forgot, in the center of the lower end of the canvas you will need to cut a groove 1.5 cm deep and 5 mm wide for a floor stop - a hand router is used for this purpose, but if you try hard, a grinder with a circle for wood will do.

Now let's fix the guide - there shouldn't be any difficulties here either.

You will need to make a wooden lining under the guide - it is needed so that the canvas does not rub against the wall during operation. Essentially, this is a beautifully processed and painted wooden slat with a thickness of 10 to 40 mm (here it all depends on the degree of curvature of the walls in the area of ​​the doorway).

The rail is attached above the opening with dowels or anchor screws - the height of its installation should correspond to the height of the canvas together with the rollers, plus a centimeter gap above the floor. After the rail is installed, a guide is mounted on it using a level.

Everything here is generally simple - a few self-tapping screws solve the whole problem. Now it’s time to tackle the doorway itself - don’t you think that you can just throw it away without taking care of its appearance?

In principle, this could have been thought about earlier, from the very beginning of work. You can decorate a doorway in different ways - it can be puttied and painted, covered with bamboo wallpaper, or simply sheathed with slats.

The best option is still a door frame assembled from a smooth centimeter strip - it is twisted with self-tapping screws and installed on polyurethane foam, after which it is covered with molding.

When the doorway is ready, you can begin the final stage of work - connecting the door leaf with the mechanism (guide). If everything was done correctly before, and you did not make any mistakes when installing the guide, then this stage of work will be quite simple.

All you need is to start the rollers installed on the door leaf on the side of the guide and check their movement, install the floor guide, which ensures a constant vertical position of the door, and also install stops that limit the movement of the door leaf

Having completed the installation of sliding interior doors, or rather their main phase, all you have to do is install special shutter slats, cover the mechanism itself with a decorative panel and, in general, that’s all. But you can do without a door rail - in most cases it is only necessary if there is a lock on the sliding door.

Why do you need a second entrance door and what material to choose from? How to install a second door and features of repair, as well as operation of the structure.

The front door in an apartment is the first and most effective way to protect your own home. Such structures can be made of various materials and their main task is to ensure maximum safety. An equally important element of entrance doors is the second leaf, which provides insulation from cold, dust and dirt. Of course, not everyone installs a second entrance door, but those who value comfort and cleanliness often wonder what material to choose from.

Today, manufacturers offer customers a huge abundance of vestibule doors, which can vary in material, characteristics and other parameters. In this material we will try to consider all the subtleties of choosing, installing and operating second entrance doors.

Do-it-yourself door frame framing

To hide the installation gaps between the block and the wall, as well as to make the door structure decorative, platbands are used.

If the surface of the platband is flat, then it is not necessary to saw it at an angle of 45°. Platbands connected at right angles look impressive. If the shape of the trim strip is rounded, then sawing at 45° cannot be avoided.

Do-it-yourself door trim installation

It is recommended to first adjust the length and saw the upper horizontal casing. Then, applying the left and right posts to it alternately, saw them using a miter box.

All that remains is to secure the trim strips with special (finishing) nails, the heads of which are invisible on the surface of the casing.

A complete picture of the process is illustrated by a video of the installation of door trims.

As soon as the door installation work is completed, you need to check the correct installation:

The bathroom door is made of embossed frosted glass

We invite you to watch the video “How to install interior doors with your own hands.” After carefully studying the recommendations for installing doors and reading the photos and videos, you can easily handle the installation of the door yourself. Correctly selected and installed doors will be a reason to be proud of your work.

Second door to the apartment: yes or no

Whether or not to install a second entrance door is up to each apartment owner. Some install them to highlight the interior design, others for functionality, and others for reliability. If you have doubts about installing an additional door, you should initially familiarize yourself with the advantages and disadvantages of the product, and only after a detailed study make a decision.

The second soundproofed wooden entrance door to the apartment is smaller in size than the main structure. The door leaf can be made from various materials, which allows you to select the design in accordance with the requirements and cost. Considering the advantages of second entrance doors, the following can be noted:

In addition to the positive qualities of the second entrance door, there are also negative aspects. Firstly, a vestibule door reduces the space of the hallway, which is especially unacceptable in small apartments. The design provides that the door leaf opens into the room, which means that there should not be cabinets, cabinets or shoe shelves directly next to the doors. Before deciding to install vestibule doors, it is important to carefully consider the pros and cons.

If the apartment actually has little space in the hallway, then as an alternative it is better to additionally insulate and soundproof the entrance metal structure. In this way, you can increase the efficiency of the door leaf without compromising space. If one entrance door is used, then it should be of the highest quality, since not only protection, but also comfort depends on this.

Positive characteristics

After installing a metal door, owners often notice that noise from the street penetrates into the room. Especially if you bought the product at a low price and it is not equipped with high-quality sound insulation.

Installing an additional structure will cope with this problem, since the air cushion between the panels will reduce the noise. In addition, the air buffer will improve thermal insulation and prevent odors from outside from entering the room.

Another weighty argument is that the second door will decorate the design of the apartment and create the integrity of the interior, because usually several interior doors open into the corridor, but the entrance door is dissonant with them in appearance.

View of the doors inside the room

An additional door can be installed from the same collection as all the others.

Even a strong, durable metal structure will not always protect one hundred percent from intruders. However, after opening one sash, thieves, noticing another, may stop.

Having considered these arguments and the advantages of an additional door, let’s summarize. An additional sash is installed for the purpose of:

• sound insulation;
• thermal insulation;
• protection against foreign odors entering the apartment;
• increasing reliability;
• interior decoration.

In a private house, such a structure can be made entirely of glass or a mosquito net can be installed. In the first option, the sash will turn into an additional window, a source of natural light. The second option will allow fresh air to enter the room and will protect against the invasion of mosquitoes or other insects.

Construction of the second entrance door

Currently, vestibule doors can be made from various materials:

Thanks to the variety of options, you can choose the most suitable material in accordance with the requirements and preferences of the apartment owner. Modern materials are distinguished by their lightness, practicality and affordable price. Depending on the requirements, you can select the optimal material for the second entrance doors. In some respects, the second panel is similar to interior doors. The second entrance door to the apartment for sound insulation is the optimal solution that will ensure comfort in the house.

Photo: There are many options for a second entrance door. Author: Ksenia Bolkanskaya

The most suitable option for a door would be a leaf that does not have glass elements, which, due to their fragility, can break and are ineffective as a soundproofing material. The door leaf must consist of a frame, crossbars, panels and a frame, which is necessary for installation. Also, the canvas must have high-quality fittings, hinges and locks. To ensure maximum protection of the apartment from penetration, the lock in the second doors must have a completely different mechanism than the one inserted into the main door. Due to the difference in secretions, it will be difficult to quickly open all the locking mechanisms.

As for the box, it is mainly made from natural hardwood. The main responsibility of the design is to ensure reliable fixation of the leaf and proper operation when opening or closing the door. The box is mounted directly in the opening using special fasteners or polyurethane foam. In the second case, the reliability of the vestibule door will be lower than that of the first.

Installing a second door

The additional structure is installed in two ways. The first option is used when the main door is already in place and the owner is not going to change it. The second option is when you plan to install a door block that consists of two leaves.

Door block installation

The second method eliminates the finishing of the door frame. This method is preferable, although there are some inconveniences when installing the threshold. It is not always convenient to step over it. But in this case, there is a way out: to create a single platform that will connect two doors at once. Plus, it is recommended to consider all the new developments that exist in the field of thresholds. Today, a movable structure has become widespread - this is a profile that is made in the shape of the letter “P”. The space inside the threshold is filled with a soft seal with a spring. When the sash opens, the threshold moves down. It can be built into a canvas of any quality, and if necessary, replaced. You should not have a negative attitude towards laying such a threshold, because it will serve as protection against the penetration of cold into the room.

What material are doors made of?

Additional doors for sound insulation can be made from various materials. The most common are: chipboard and MDF panels, natural wood, plastic and a combination of materials. When deciding on the choice of a suitable material, it is important to take into account the characteristics of each of them.

Plastic canvas

Plastic doors are made directly to your dimensions and parameters. It is worth noting that this model has a high level of noise and sound insulation, modern design, durability in operation and is easy to operate. You can order a door of any design and style. The colors of the canvas can be absolutely any, and double-glazed windows can also be used as on balcony doors. All details of the order are discussed directly with a specialist. The cost of the finished product depends on the complexity of the design, dimensions and other characteristics.

Classic wooden doors

Perhaps everyone is accustomed to the fact that wooden doors are distinguished by their reliability, environmental friendliness and high cost. However, if we talk about such a material as wood, it is important to note that such products are distinguished by their unique beauty. A wooden door can become a real addition to the main interior or even a highlight. A product made of natural wood is perfect for a classic design, warm and at the same time strict. For the second entrance door, it is advisable to use hardwood, as scratches may form due to constant use. Another advantage of wood is that if scratches or other defects appear, everything can be corrected using varnish. The service life of wooden doors is measured in decades.

Door made of laminated chipboard

Chipboard is a wood material made from chips. Pressing technology produces a durable and reliable material that has a relatively low cost. Resistance to mechanical stress is ideal for the design of second entrance doors. The outer part of the chipboard board is covered with a polymer coating, which can have different colors and shades. In addition, the polymer coating provides additional strength to the fabric structure. If a vestibule door will be used in an apartment, then this material is ideal. If installed in a private house, moisture from the street will cause the slab to swell, and the door leaf will have to be replaced soon, since chipboard does not withstand moisture well.

MDF boards for doors

The production technology of MDF panels involves the use of fine sawdust mixed with an adhesive. During manufacturing, water-repellent components are also added to the raw materials, as a result of which the material perfectly withstands a humid environment and does not react to it. The door structure consists of a frame covered with MDF panels. The outer decorative layer is made of film, so there can be a lot of variety of textures and colors. The main advantage of an MDF door is its relatively low cost.

Should you choose metal or wood?

Of course, the second doors are the so-called second line of defense, so the iron structure will be much more effective. However, it is also worth considering other requirements for the canvas. The second entrance door to the apartment with sound insulation provides protection from noise, dust, cold and other factors, and a wooden surface will cope with the basic requirements much better and more efficiently.

If you want to protect your apartment from penetration as much as possible, then it is better to pay special attention to the main entrance door, and it is better to install a wooden second one. This canvas will provide comfortable conditions and aesthetic appeal to the hallway.

Double door design

A double entrance door differs from a standard entrance door only in dimensions and some design features. And the materials used for its manufacture are the same: iron (see Installing iron entrance doors: instructions for use), wood, wood-like materials, and less often - plastic. And also their combinations.

If the front door leaves are of equal width, it is called double-leaf, if different - one-and-a-half-leaf. In both cases, one blade is working, and the second is fixed in the box using lower and upper bolts or special crossbars.

If you need to bring a large item into the house, the second door can be easily opened from the inside. Although for one-and-a-half-leaf doors, the narrow leaf may be stationary and not open.

How to install an additional entrance door

An internal entrance door to an apartment with sound insulation is installed without unnecessary difficulties, and this work can be performed by any owner if he has the necessary tools. For installation you will need: a hammer drill, a screwdriver, a tape measure, a level and construction foam. The following hardware is used: screws 70 mm long and anchors. If necessary, platbands are installed along the edge of the opening in the hallway.

When installing the door, you should follow a certain procedure:

These installation steps are applicable for wooden, chipboard and MDF doors. In the case of plastic installations, installation work is carried out by specialists.

Assembly and installation of the door frame

Before you begin assembling the box itself, you need to check the conformity of the timber, and if discrepancies are identified, adjust it to the required dimensions. Next, the procedure is as follows:

• After the marking has been carried out, it is necessary to cut the box beam. The cutting angle should be 45?. It's easier and faster to do this with a miter saw. However, a fine-toothed hacksaw will also work for this job.
• The next step is inserting the hinges. They are installed on vertical parts. They are inserted using a router. If you don't have one, a hammer and chisel will do. However, if you don’t want to fuss with hinges, it is best to purchase overhead hinges (“butterflies”). They are installed without insertion.
• Assembly of all parts into a single structure. The connected elements are twisted using several self-tapping screws.

It is worth remembering: in order for the wooden elements to remain intact, without cracks, during the process of screwing in the screws, you should drill a hole immediately before this. Accordingly, if the diameter of the self-tapping screw is 3.5 mm, then the drill should have a diameter of 2.5 mm.

Correct operation of the entrance door system

When using doors, it is periodically necessary to carry out preventive maintenance, since the service life depends on this. The performance of a double door with a vestibule for sound insulation will deteriorate if care and maintenance measures are not carried out in a timely manner. Inappropriate care and maintenance will lead to mechanism failure. There is a certain list of activities that must be performed:

As the door is used, the door leaf may sag over time, and this problem can be eliminated by replacing the hinges.

Do-it-yourself installation of interior doors (video)

Well, now it's time to finish the article. All the material I wanted to share has been reviewed. I hope it will be useful to you, and you will use it if you need to install double interior doors with your own hands. Improve your own practical skills and gain new knowledge, they say: “It’s never too late to learn!” That's all, thank you for your attention, successful and easy repair!

Types of materials for soundproofing the second (vestibule) door

Second entrance doors should protect the apartment from dust, dirt and noise. It is quite difficult to ensure effective sound insulation of a vestibule door, since using different materials will negatively affect the appearance of the structure. You need to take care of sound insulation by installing wooden doors without glass inserts in advance. Such a canvas will most effectively protect the house from various sounds from the street and corridor.

If doors made of other materials have already been installed, then as soundproofing you can: seal all the cracks, stick on a good seal, use upholstery with a soundproofing lining for the outer part of the door leaf. All these measures will help minimize the degree of sound penetration inside the apartment. Also, as an option, you can try to soundproof the first entrance door, which will increase protection.

Do-it-yourself noise insulation using upholstery

If you decide to make noise insulation, then the optimal solution for the second entrance door would be to use upholstery. You can do the work yourself without resorting to the help of a specialist. First you need to check the door leaf for cracks and chips. If there are any, then they must be sealed. The same goes for the door frame. There is no point in soundproofing if there are cracks between the door frame and the wall.

The upholstery is installed on the outside of the door, and mineral wool, synthetic padding or foam rubber are used as filler. It is important to know that soft materials effectively retain sounds. The filler is attached to the door using a construction stapler, since its staples are unnoticeable and securely hold the material.

The outer upholstery can be made of leatherette or dermantine. The material is glued along the entire perimeter of the door leaf, hiding the filler. The whole process of finishing the door will not take much time, and you can do everything yourself.

Dimensions of double doors

Let us repeat that double doors can have leaves of the same or different widths. Options with the same ones are called symmetrical, while those with different ones are called asymmetrical (asymmetrical). You can often come across the term double and one-and-a-half doors, as well as equal and unequal doors. They also display the ratio of the width of the sashes.

Door blocks can be symmetrical or asymmetrical

The minimum width of a double-leaf door is 80 cm. These are two leaves of 40 cm each. Just keep in mind that the opening should be 10 cm larger. That is, the minimum size of a doorway for a double-leaf door is 90 cm. In extreme cases, it can be 88 cm The maximum standard size is 180 cm (190 cm doorway).

Double-leaf interior doors - standard sizes

Keep in mind that the standard sizes of frames for interior doors come in increments of 20 cm. The standard leaf width changes by 10 cm: 60 cm, 70 cm, 80 cm and 90 cm. If you need the same leaves, there are only five options for openings:

• 90 cm;
• 130 cm;
• 150 cm;
• 170 cm;
• 190 cm.

The doorway may be slightly wider than the specified values. A reduction of 1-2 cm is also allowed, but no more. If the existing passage does not fit into these frames, you can either use sashes of different widths or order according to your sizes. The height of the opening is also specified: standardly it should be 2.06 - 2.10 m.

Dimensions of door openings

By the way, finding narrow double-leaf interior doors can be problematic. Not all factories make options with two leaves for a 90 cm doorway. It is quite normal for a standard swing door to fit here. In this case, you can try to find narrow halves from unequal sets (with two sashes of different widths). But you will most likely have to cut the hinges and install the box yourself.

Large doorways

If the gap is larger, it will need to be sealed with something. You can do it before installing the door, you can do it after. The gap is filled with lightweight material, then plastered, aligned with the rest of the wall.

You don’t always want to reduce the height of the opening. Then you can order a vertical decorative strip (upper transom) similar in style and color to the door. This is definitely an individual project, and the door frame is more complex.

If the doorway is high, you can install an upper transom above the door

What to do if the doorway is wider? If it is, for example, wider than two meters? This doesn’t happen often in modern layouts, but you never know. Maybe you got a house with just such wide passages. You can, of course, add extra space, but there are other ways. One possible option is to make inserts of the same design on the sides. They are called side transoms. They are separated from the functional door by powerful pillars and cannot be opened.

In a wide opening, fixed parts of the same design can be added

Side and top transoms are often used together. Since the doorway is usually both wide and high. But they can also be used separately. For example, Stalinka buildings have very high and narrow openings. This is where they either add extra height or install upper transoms. Someone goes the other way - widens the opening to make it look more proportional. In general, there are different design methods.

Characteristics of the door leaf

In the design of the second entrance doors, the canvas plays an important role. Thanks to this design element, comfortable conditions are provided in the room. Depending on the material used in the construction of the door leaf, the characteristics of the product may vary.

The door leaf is based on a frame made of timber. If the door is made of solid wood, the design may vary. In addition to the frame, there are also spacers and an outer surface. A high-quality second entrance door can keep out cold, dirt and dust, thereby making the hallway comfortable and beautiful.

Characteristics of the door leaf

Technical characteristics as selection criteria

The cost and weight of the door depends on the chemical, physical and geometric characteristics of the metal. Have you noticed that we are not talking about hardware? Iron is a simple substance, a chemical element that is rarely found in its pure form even in nature. Door manufacturers use alloys of iron and carbon - carbon steel.

The content of carbon and alloying components is strictly regulated - up to 11% and up to 0.6%, respectively. The optimal steel grades for making doors are those that are classified as medium-alloy and medium-carbon.

• Hot rolled. It is distinguished by its low price, dark color, and high susceptibility to oxidation processes. Easy to process. GOST 19903 is written on the door documents.
• Cold rolled. The price is a little higher. The color is light gray, the surface is smoother, without scale. The homogeneous structure provides high tensile, tensile and bending strength. The steel is weather resistant. It is subject to the GOST 19904-90 standard.

How thick should the sheet metal be? This figure also needs to be found in the technical documentation for the door.

• 0.8-1.0 mm. Doors for storage rooms, outbuildings, utility rooms.
• 1.0-1.5 mm. A practical option for offices in secure business centers and various institutions.
• 2.0-3.0 mm. The optimal solution for doors to apartments, vestibules and entrances.
• 3.5-4.0 mm. Suitable for private homes for permanent and seasonal residence. Resistant to temperature deformation.

Are you choosing doors made of thicker metal? Be prepared for additional costs. The cost increases due to more expensive material, the need to use a reinforced frame and powerful hinges, and a completely different approach to the installation of the structure. On average, metal entrance doors for apartments, offices and houses weigh 70-75 kg. Doors weighing 90-100 kg or more are installed in financial institutions, weapons storage rooms and other critical premises.

Attaching the leaf to the door frame

High-quality vestibule doors have a groove along the entire perimeter of the leaf and door frame, the dimensions of which should be equal to two millimeters. To get a perfect fit of the leaf to the door frame, you should carefully measure the door set when purchasing. If you bought doors and a frame, and after installation it turns out that the gaps are large, then you should replace the door leaf or stick on an additional seal. Correct connection to the door guarantees maximum protection of the room from the penetration of sounds, cold and dust.

Description: Why do you need a second entrance door and what material to choose from? How to install a second door and features of repair and operation of the structure.

Glass and other inserts

Interior 2-leaf doors can be either solid or with glass inserts. You can find all-glass sashes, or maybe solid glass with a frame. In models with doors of different sizes, the smaller one can be with or without glass (solid).

There is no need to worry that it is dangerous with/from glass. Tempered glass is used, which requires a lot of effort to break. And even if it breaks, it will fall out in a bunch of fragments with soft edges or remain hanging on the film. It depends on the type of glass.

Decorating with glass was invented a long time ago

Glass doors and inserts are good because they allow you to illuminate the corridor when the doors are closed. Of course, you can put a motion sensor there to turn on the lights, so as not to walk in the dark. But the presence of daylight is often much more pleasant than artificial lighting. They also add great variety to the design. And don’t think that double doors with glass are only available in the classic style. There are a sufficient number of models that are more suitable for modern interiors than classic ones.

Conclusion

Of course, whether to install a second entrance door or not is up to everyone. Considering all the advantages of adding entrance doors, we can say with confidence that an additional leaf will not be superfluous. Using second entrance doors you can protect your home from dust, debris and cold as effectively as possible, while reducing the noise level. Also, the vestibule door will become an additional barrier for burglars, and with the use of several different locks it will be practically impenetrable. If you are installing second doors, it is important to choose and install them correctly.

Door lock

If the main function of the first, front door is to protect the house from burglars, then the second one performs completely different tasks, and therefore does not need to install an equally reliable lock. Installing a full-fledged lock on the second door is possible if you use a trick: place a modest wooden door on the outside, and a strong metal one on the inside.

It is known that an expensive front door often becomes a bait for burglars. In fact, the second and first doors in this situation change roles. The lock for the second door has very special requirements. On the one hand, it must hold the door in place (it should not, say, open due to drafts). On the other hand, it must look aesthetically pleasing or be completely invisible.

The ideal option is magnetic locks and rotary handles. They will perform the main task (prevent the door from opening spontaneously) and will not spoil its appearance. The magnetic lock will not be noticeable at all: the tongue is hidden inside the canvas until it is attracted by a magnet located in the receiving part of the riser. It turns out that for the second door one rotary or push handle is enough.

Choose: beauty or sound and heat insulation. A door with a threshold looks more aesthetically pleasing, but provides less protection from noise and drafts.

Wardrobe brush

If you are not ready to spend extra money on a special retractable threshold, go to the construction market, to the built-in wardrobes section. It is necessary to find the so-called sealing brushes, which are glued to the compartment canvas to protect it from dust. They can serve as an alternative to the threshold if the gap between the floor and the interior door is small.

Many people have a lot of questions when choosing a metal entrance door:

• Should I buy a ready-made door or order a new one?

• What nuances affect the quality of doors?

• Which burglary resistance class is best?

You will find all these questions and answers to them in this article.

Should I buy a ready-made door or order production?

It all depends on the size of your doorway. As a rule, finished doors have standard sizes - usually there are only 2-3 of them. These sizes may not always suit you. For proper installation of a metal entrance door, the doorway must be larger than the door frame.

You should never hammer a door frame into a doorway so as not to deform or warp the frame. Such a door may jam in the future.

A very large gap between the door opening and the frame is also unacceptable. Such a door can subsequently be easily pressed out with a jack or other methods.

Of course, the doorway can be adjusted to fit ready-made doors, but in addition to the expense of expanding the opening, the supporting structure may be damaged, which can cause unexpected consequences.

A finished door is usually equipped with locks from a specific manufacturer, and, based on practice, these locks are very difficult to replace; you have to completely disassemble the door leaf, attach other fasteners, etc.

Ready-made doors also have a big advantage - they are always cheaper than custom-made ones, since they are produced using an assembly line method.

Metal entrance doors - what affects the quality?

The quality of the door is influenced by the design. Each metal door consists of a leaf and a frame. The box can be profile or corner. The corner model can withstand heavy loads, because the thickness of even a very narrow corner is at least 3 mm. The disadvantage of a corner box is reduced thermal insulation.

Hollow metal profile box up to 2 mm thick. It looks more aesthetically pleasing and has good thermal insulation. The disadvantage of the profile box is the thickness of the metal, since the moving parts of the lock, especially the “tongue” subsequently wears away the metal over time, as a result of which, when closing the lock in the door, you have to press it.

Some manufacturers make a profile box from a corner, so it provides both thermal insulation and load resistance.

The door leaf can also be constructed from a profile pipe or angle. Inside the box, stiffening ribs are certainly installed and insulated, then sheathed with metal sheets on one or both sides and decorative overlays are placed.

From experience we can say that stiffeners made from profile pipes make metal entrance doors more “stiff”. Also, it should be noted that it is not at all necessary to sheathe the door with metal sheets on both sides; it is enough to do this only on the outside with 3 mm thick metal.

What burglary resistance class should I choose for the entrance door of an apartment?

First, let's find out how doors are opened.

Professional - with the help of rolls, master keys, bumping master keys and other professional tools of burglars or emergency workers (which are not sold in hardware stores).

Sometimes the metal structure itself can be made of very high quality and expensive locks installed, but, for example, with a roller, people with extensive experience and skills in the field of opening and having the necessary tools can open almost any lever lock in 20–30 seconds.
