How to choose the front door to a private house. What to do if the front door in a private house freezes through The metal door freezes what to do

Entrance doors are a kind of bastion, which must reliably protect its owners from unauthorized entry, as well as provide full-fledged temperature and humidity conditions in the house. A good door panel prevents cold air from entering from outside, but sometimes even professionally installed structures freeze up. What exactly should be Entrance door V a private house so that it does not freeze even in severe frost, and you will learn how to solve problems of this kind from our article.

What is the essence of the problem?

In your private house, the entrance Iron door freezes through. This is a very unpleasant situation, but, unfortunately, very common. Of course, there is no point in panicking in this situation, but you should not let the problem take its course.

Why does the front door in a private house freeze through? There are a number of explanations for this:

1. Sharp temperature jump. When there are frosts on the street, and heating devices are functioning with might and main in the house, then in the end we get a huge difference between temperature conditions from the outside of the door panel and the inside. From the side of the room on the door, due to a sharp temperature drop, drops form and, cooling down, they freeze.

Condensation in a significant amount - the cause of freezing

1. High thermal conductivity facing material. Doors made of metal cool down quickly, thus becoming a source of cold. And due to the same condensate, it is converted into drops, which, accordingly, become frost.
2. The presence of one door in front of the exit to the street. If the door leaf is in full contact with outdoor weather conditions, then sooner or later, there will be a freezing problem.
3. Sagging or lack of insulation material in the panel. High-quality samples must be insulated, but, unfortunately, not all models of such structures are equipped with heat-insulating layers. If low-quality “consumables” are used, then after a while they lose their performance and cease to perform their functions.

Insulation should be placed in separate sectors, in which case its subsidence or wrinkling is excluded

Much depends on the quality of the insulation itself. If work on the insulation of the front door is carried out independently, choose a heater famous brands with quality certificate.

An example of high-quality (left) and low-quality (right) insulation

1. The presence of gaps on the door panel. Defects of this kind may remain after the installation of the product or occur during the operation of the structure. Cold air masses pass through the cracks. Moreover, precipitation can enter through such defective places.
2. Poor sealing of butt joints. The rubberized sealing cuff, which is pasted over the entire perimeter of the loot, provides protection from drafts and frost, but after a while this element falls into disrepair and loses its performance characteristics. In addition, far from always people install a sealant.

In addition, often the metal front door in a private house freezes due to deformation of the component parts of the opening. Due to prolonged use or improper handling, the elements of the opening can be deformed, which, in turn, leads to the formation of all the same cracks and gaps.

Often freezing door leaf is due to its thin walls. It is an insignificant barrier to the path of cold air masses. Ennobling your home with a metal door, be extremely attentive to its filling. An unprepared door panel is not able to withstand the harsh winter frosts and will be bound to frost. And there is no getting away from this, any model of domestic doors will sooner or later begin to freeze.

The main reason why the front door in a private house freezes through is too thin construction. The thinner the sheets from which the panel is made, the more it will be covered with frost.

What is the danger of freezing the door leaf?

Most people who are faced with such a problem prefer to let things take their course and wait for the long-awaited warming. But at the same time, such a nuisance should be resolved immediately, since freezing can lead to other equally pleasant situations:

• loss of thermal energy, which can lead not only to discomfort, but also to the development of colds;
• the presence of frost on the door leaf leads to cracking of the outer panel, which in turn significantly reduces the life of the structure;
• if you do not deal with freezing, then because of this phenomenon, the lining will begin to deteriorate;
• the course of such a process causes the presence of frost on the slopes of the front door, which also quickly brings them into disrepair;
• violation of the full functioning of the locking mechanism, as well as handles;
• Excessive humidity in the room leads to the development of mold and mildew.

In addition, the frozen door leaf undergoes deformation during use. Even in warmer times of the year, the door will continue to seep through, and over time it will simply stop closing.

As soon as freezing of the front door is detected, it must be removed and insulated at the first warm windows. Even one very cold winter enough to have to change the entire block in the spring.

How to prevent freezing

When frost is found on the door panel, it is necessary to make every effort to solve the problem as soon as possible. Qualified specialists offer three options to remedy this problem.

Checking the insulation

At the first sign of freezing, check the insulation

If the front door freezes through, then the problem may lie precisely in this. Either you became a victim of fraud and you were given a sample that was not equipped with an insulating layer, or the heat insulator turned out to be of poor quality and eventually settled in the canvas or crumbled. According to statistics, 9 doors out of 10 freeze through precisely because of the lack of insulation material or its poor quality.

In this case, you need to remove the inner decorative sheet or upholstery and check the condition of the insulation. If it is not there or it has become unusable, then you need to replace it with a new one. Styrofoam, polystyrene, mineral wool, fiberglass cloth act as a good heat insulator. Such materials are placed in the inner cavity of the door leaf and fixed with a quick-drying adhesive base. A good alternative would be a self-adhesive insulation that will protect the room not only from heat loss, but also from extraneous sounds and noise coming from outside.

It remains only to “sew up” the structures with a decorative coating.

Interior trim replacement

Replacement interior decoration

Often, freezing of the front door in a private house occurs due to the insignificant thickness of the inner door leaf. If the structure from the inside is an MDF-sheet with a thickness of 0.6-1 cm, then the cold will easily penetrate into the room.

Loot check

seal for door frame

Often the cause of the formation of condensate and hoarfrost is a poorly insulated loot. If the door system is equipped with a metal box, then in order to protect it from interior you need to trim the frame with slopes or MDF. This method of resolving a problem situation is not difficult to implement and is financially beneficial in comparison with others. alternatives troubleshooting.

At the same time, one should not forget about the sealant, which “passes” along the perimeter of the entire box and the outer edge of the door tight. The presence of insulation will significantly reduce the number of cold bridges and make the door silent.

Adhesive rubber seal

Knowing what the front door should be like so that it does not freeze, you can take care of its insulation in advance and prevent the formation of frost.

Many people are faced with such a problem as fogging or freezing of the front door. Owners of private houses suffer especially from this, the doors of which often have direct contact with the street.

Fogging and freezing of the door is an extremely unpleasant thing and, moreover, it also damages the door, which simply becomes unusable in the shortest possible time. Therefore, if you notice the first signs of condensation or freezing on the door, start acting immediately.

But, first, let's try to figure out why the problem of fogging and freezing of the door arises, and then we will find ways to eliminate the troubles associated with condensation on the door.

Causes of door fogging

The main and most common reason for the appearance of condensate is the banal difference in surface and ambient temperatures. This is where the physical law comes into play. state of aggregation water, the catalyst of which is the metal surface of the door. Wooden doors, as a rule, do not bring such problems to the owners, and all because the thermal conductivity of the metal is three hundred times higher than the array.

And, if the first reason why the door sweats turned out to be trite, then the second is no less simple - the doors are not insulated or this work was done poorly.

Other reasons may be poor mounting of the keyhole or handle to the metal surface. Weak fit of the door leaf to the frame due to errors in the installation and installation of the metal deri. Specialists also call such places "cold bridges", which can lead to fogging even insulated doors. So, to make it clearer, we structure the reasons why the door fogs up:

• Critical difference between ambient and indoor temperatures.
• Lack of insulation or poor-quality insulation of the internal cavity of the door.
• "Cold bridges" - lock holes, handles or a weak fit of the door frame to the walls of the house.

Reasons why the door freezes through

The reasons why the door freezes are almost identical to the reasons why the door sweats. It can even be said that the freezing of doors is a consequence of sweating. But, so to speak, to consolidate the material, we repeat once again and clarify some points:

• Critical temperature difference. When it is cold outside, and all the batteries and heating devices are working in the house, this gives a significant temperature difference between the outer and inner door leaf, which leads to the fact that the door sweats, and when it cools down, it freezes.
• Climatic temperature fluctuations in the off-season.
• The absence of insulation in the door cavity or its shrinkage due to the dishonesty of the door manufacturer and the poor quality of the insulation material.
• Small thickness of the iron sheet and a minimum of door cladding.
• Cavities, cracks and gaps in doorway, which are the very "cold bridges" that we mentioned above. Such defects may appear as a result of door depreciation or initially - during installation.
• Low sealing of the joints of the box structure. The rubber that runs along the perimeter of the box can become thinner or dry over time, which leads to the loss of its main functions - protection from drafts, frost and precipitation. In addition, many unscrupulous fitters "forget" to install it altogether.
• Deformation of parts of the door frame. As a rule, this happens with rough depreciation or improper distribution of loads on the details of the opening, which will lead to the appearance of "cold bridges".
• One door is basically not enough because of climatic conditions or private houses.

What threatens freezing doors

In the early stages, it is far from always possible to recognize that the door is freezing through, and when this problem takes obvious forms, the amount of work to eliminate it can unpleasantly surprise and hurt your pocket. But let's try to isolate all the signs of this "disease" of the door at an early stage.

Under the influence of constant humidity and temperature changes. The door leaf is the first to be surrendered, which swells, peels off along the edge; glued decor in the form of panels, laminate or veneer - swells and may fall off. Not only the appearance is lost when the door freezes, but the elements of the box also become unusable: slopes, sills and platbands. Over time, the problem of freezing the door will grow like a snowball, and lead to breakage or jamming of the lock, as well as limiting the movement of the door leaf. As a result, the door will have to be completely replaced.

But that's not the whole bunch of troubles. Moisture can get on the walls and floor, which can provoke the appearance of fungus and mold.

How to fix the problem of condensation.
Additional measures to protect the door from freezing and fogging.

So, you have identified your problem: the door is sweating and freezing. Now let's think about how to get rid of these troubles.

If the problem lies in the insulation, then the door must be removed from the hinges and disassembled. Manufacturers can arrange the insulation in different ways: inside a solid product or under an additional panel. If there are additional stiffeners in the door structure, they will ideally help prevent the insulation from sagging and for a sufficiently long time the problem of door freezing will not return to you. If there are no such ribs, and the design allows them to be installed, it is advisable to do this.

To use insulation so that the door does not sweat and does not freeze, you can completely different. Experts do not limit the choice and recommend everything: loose, soft and hard types of substrates. Loose, as a rule, are used to insulate non-separable door structures. In other cases, use sheet heaters. Soft ones lose their shape faster than they are significantly inferior to hard heaters. But the most best option- foam blocks.

Professionals advise combining insulation and a heat-reflecting substrate, fixed with adhesive mixtures to fix the position. In such works, mounting foam is also indispensable, which will reliably protect all joints from the penetration of moisture and cold, and also exclude the appearance of "cold bridges". When the insulation securely “clings” to the surface of the door sheets, collapsible door structures can be assembled and returned to their rightful place.

Another of the most reliable ways to eliminate the causes that cause the door to sweat and freeze through is to increase the thickness of the door leaf.

Even an insulated door can sometimes continue to sweat and freeze. This is no longer due to the quality of the door, but due to harsh climatic conditions. There are only two exits. About the second - the installation of an additional door or an extension of the veranda - we'll talk later. But about the thickening of the door leaf - now.

For such work, you can use various materials, which not only insulate and seal the door, but also preserve its aesthetic appearance. Often use MDF sheets. They have sufficient strength, are resistant to many types of impact, provide additional sound and heat insulation. In order for the result of the fight against freezing to be reliable and durable, the thickness of the MDF sheet must be at least twenty millimeters.

Soft upholstery is another option to prevent freezing and fogging of doors. This is an old and proven method that people have been using for many years. Most often used on wooden doors. All that is required is leatherette, an insulating substrate and a heat reflector. For maximum effect, it is also desirable to make insulating rollers around the perimeter of the door frame.

In some cases, when the door sweats and freezes, it is enough to confine itself to manipulating the door frame.

Cracks, voids, crevices - all the same "cold bridges" that let cold and moisture pass through the door frame, lead to intense freezing and fogging of the door edges and the frame itself. If the door is wooden - unwanted guests in the form of fungus and mold will not keep you waiting long. In this case, there is only one option - overhaul and insulation of the loot. The door will have to be removed from the hinges, although it will not be subjected to any procedures. We fill the hole itself with insulation and mounting foam.

Small cracks and cavities can be eliminated with putty and sealant, and in cases where the wooden shell has begun to dry out, use a special primer or glue.

A metal shell can be saved from freezing by framing MDF panels or slope equipment, which will not only have a protective effect, but also perform a decorative function.

There are times when steel door freezes around the perimeter of the canvas. In this case, it is enough to simply seal the joints - installing an additional sealant. In principle, such a gasket should be in any door, regardless of whether the door freezes through or not.

Such a gasket can be made from a special rubber material, which has a small width and adapts to the shape of the box with gutta-perchio. If you do not have the opportunity to use such a rubber material, then a hollow rubber tube or the foam rubber we are used to is quite suitable, and even better its modern prototype is isolon, which is lighter and has a denser structure.

All of the above options are glued to the perimeter of the box with a special adhesive tape. And do not forget about the sills, but you need to work with it carefully so as not to disturb the tightness of the door leaf and, at the same time, so that the door does not move.

Another of the options that we promised to consider is the installation of a door. Sometimes all of the above options simply cannot save the door from fogging or freezing. Then it is worth resorting to the latter - double door. As a rule, this happens in cases where the apartment is located on the ground floor or in a private house, but the provocateur of all these troubles is a certain climate.

When installing an additional door, the main thing to observe the main condition is to make the doors multidirectional. And, of course, make sure that there is enough space in the corridor for such insulation.

In private houses, you can replace the installation of a second door with the construction of a dressing room or a veranda. But it's up to you how to fix the problem when the door sweats or freezes.

Owners of private houses often face the problem of freezing the front door. Constant contact with cold air and precipitation leads to the fact that in winter there is a possibility of reducing its thermal insulation properties. If the lock in the door began to jam, it opens worse, condensation is observed on the inside, which means that it is urgent to find out the causes of freezing and eliminate them. Otherwise, there is a risk not only to freeze in your house, but also to get damage to the door, which will lead to a decrease in service life or breakage. Together with the door, the lock can also freeze - then there is a risk one day simply not getting into the house.

Causes

So, the first thing you need to find out the reasons for the freezing of the front door:

• The temperature is too low outside, but in the house, on the contrary, it is quite high. This leads to the formation and freezing of condensate.
• The insufficient thickness of the door leads to the fact that it quickly freezes and conducts cold into the room.
• Fluctuations in outdoor air temperature.
• The presence of cracks in the locks through which frosty air passes.
• The absence of insulating materials between the door and the frame, their complete or partial wear.
• Deformation of the door structure appears, skew occurs and gaps form.
• If the space between the sheets in a metal door is not insulated or low-quality materials are used, the thermal insulation is significantly reduced.

Among the above reasons, one can single out factors of external influence and errors or breakdowns of the structure itself. If the influence from the outside cannot be adjusted in any way, then you can try to cope with the rest of the reasons.

What to do

There are several options for solving the freezing problem. You can use one or combine several.

Replace the insulation inside the door

The inner filler of the canvas may lose its insulating properties over time. Its service life directly depends on the quality of the materials used. However, even the most expensive heaters will not serve you forever, so you can try to fix the door freezing problem by replacing the filler. Options for this can be foam blocks, mineral wool, corrugated cardboard, foamed polyurethane, bulk materials. It is also recommended to change the filler just for preventive purposes.

Install an extra door

Perhaps the right solution to prevent freezing of the door would be to install an additional one. However, this requires a number of conditions. If the second door is supposed to be placed inside the house, that is, you need to have a sufficient supply of space, because it will reduce the area of ​​\u200b\u200bthe corridor. Installing it outside is even harder, because for this you will have to complete the veranda. It is necessary to design the second door so that it does not interfere with the opening of the first door. As you can see, this is a very expensive method of warming a house.

Increase the thickness of the door leaf

The thin metal used in the manufacture of the door cannot be made thicker. An increase in the thickness of the door leaf can only be done by replacing the facing material, for example, with high-quality MDF panels (painted, veneered, laminated). During the production of the latter, a film layer is applied to its elements, the function of which is to make the material resistant to external influences. You can also use plastic, artificial leather (mainly for wooden doors). It should be borne in mind that the thicker this layer is, the greater the likelihood of maintaining dryness.

Eliminate defects in the door frame

If there are cracks or gaps in the wall of the house, it is worth repairing them with building materials. You can stick insulation tape around the entire perimeter of the door frame. You need to make sure that there are no cracks in the frame. If they are still present, they are sealed with putty or sealant.

Seal all existing gaps

Installing a sealant, which is often rubber and foam rubber, will help solve this problem. An additional function of this gasket is soundproofing. However, when installing these elements, it should be taken into account that they should not interfere with the operation of the door, not complicate the process of opening it. It is possible to seal the gaps between the lock and the canvas using mounting foam. It is important not to forget that all the small cracks and gaps together can greatly reduce the thermal insulation of the house.

If the door is still frozen

The above methods will help to some extent to increase the thermal insulation of the front door. If you do not have special skills to carry out all these actions, or you do not have tools and materials available, you will have to use the services of professionals. It may well happen that the efforts and funds expended on repairs and improvements old door, do not justify themselves. If, nevertheless, a set of measures has been taken to improve the thermal insulation in the house, but this does not help, or the situation improves only for a short time, you should think about changing the door.

A new door will not only make your home warmer and more comfortable, but will also help to avoid such unpleasant phenomena as mold and fungus. It also saves a lot of time and effort. If you start high-quality care for the front door while it is still new, you can significantly extend its life. And it will serve faithfully for many years.

How to find out that the iron door freezes through? What to do in this case? There are many methods that will help in solving this problem. Freezing is often associated with the mechanisms that are included in its package.

Freezing of the entrance structure

How to determine that the door leaf in a private house is freezing?

Often people begin to notice late that a metal door freezes through in their home. If this is noticed at the initial stage, then it is easier to solve the problem. Due to the fact that condensate accumulates on the input structure from changes in temperature and humidity, there is a negative effect on the canvas. Initially, the canvas begins to increase in size, and then a kind of edge appears. If the installation is decorated with decorative elements, then already at this stage they will become unusable and lose their appearance and aesthetic qualities.

Attention! If a metal sheet freezes, then the locking mechanism will suffer along with it, it will simply fail. If the door leaf is made of wood, then because of this problem, fungus and mold begin to develop.

Freezing of the input wooden model

Consider the main signs by which you can identify the initial freezing:

• Jamming of locking mechanisms in the cold season;
• The presence of constant drafts in the room;
• Condensation formed on the door from the inside;
• If the facing material is swollen, the door may freeze around the entire perimeter.

Attention! If there are the above prerequisites, then do everything possible to prevent the structure from freezing.

What can cause freezing of the input structure?

Each owner of the house is interested in why it freezes door structure. The reasons for this may be different. The installation takes on a freezing appearance if it is made of low-quality material.

Consider the main causes of freezing of the input structure:

• Sharp temperature changes. That is, if a low temperature prevails on the street, and the room is heated, then a temperature mismatch occurs. Condensation settles on the door, which eventually freezes;
• High level of thermal conductivity of iron material. The design, made of iron, has the feature of quickly cooling down and letting cold into the room;
• Small thickness of the door leaf. If the iron is thin or the structure does not have internal insulation, such a door lets cold air into the room, which leads to freezing;
• Existing gaps and cracks in the structure. More often, such a mistake is made in the initial process of installing the door. Cold air enters through these cracks;
• skew doorway. In the process of prolonged use and improper handling of the structure, deformation occurs, due to which gaps are formed.

Changing the insulation of the input installation so that freezing does not occur

Let's move on to immediate action and figure out what to do if the structure freezes. Initially, if metal doors with a sealant freeze in a private house, then you need to pay attention to the sealant in the design. If the door is of high quality, then it is well insulated. If the installation was purchased in a ready-made version, then the manufacturer should have thought about this aspect. If the door is made by the owner, then this is his personal mistake.

Seal replacement

Initially, the replacement of the seal begins with the fact that the door is removed from the hinges and its canvas is disassembled. Depending on what kind of design we have in front of us, the seal can be located inside the whole installation or under the panel.

Soft or loose substrates are used, there are also dry types. The latter type of seal is used in models that cannot be disassembled. As for other types of doors, sheet-type heaters are used for them. Soft seals are rarely used, as they are of little use. Therefore, nowadays they are accustomed to using foam blocks.

To prevent freezing from repeating, experts recommend using heat-reflecting sheets in work, which are fixed with glue, when using a sealant. To begin with, the necessary sheet is cut so that it is well suited for the door leaf. The heat reflector and the foam itself are fixed with glue on the door frame.

Attention! After the final adhesion of the material to the surface, the structure can be returned to its place.

The possibility of increasing the thickness of the canvas

If, when the above conditions are met, freezing does not stop, then do not give up. All due to the fact that the door has insufficient thickness. How to solve such a problem?

Increasing web thickness

The entrance structure should not only have high strength and be outwardly beautiful. To achieve this factor, various Decoration Materials with the help of which the finishing of the canvas itself is made. Often today external design made from veneer. It can provide the front door with additional sound and thermal insulation. If freezing occurs, then the veneer suffers first. Due to this, the front door should be finished with high quality material.

Attention! If the layer of interior trim is thick, then this can be a kind of guarantee against freezing.

Sealing existing joints in the installation

What to do if the freezing of the input structure occurs along the perimeter of the web? by the most simple solution will be - sealing existing joints. They install a seal that prevents the passage of drafts and cold air.

Often, a simple rubber-based sealant is used for such work. You can also use a foam seal. Isolon is considered the most modern sealant. You can find it in the construction market, by appearance it resembles foam rubber, but its qualitative properties are much higher.

Installation of the second entrance door

To prevent freezing of doors, the owners of apartments and private houses resort to installing a second front door. This method not only helps protect the room from cold and condensation, but will also provide additional protection against burglary.

Second entrance door

Before installing such a design, decide whether there is enough space in the corridor for the second door? So that the installations do not interfere with each other, the installation is carried out so that the canvases open in different directions.

Currently, the problem of freezing the door leaf can be faced not only by those who live in a private house, but also in an apartment. Which method of insulation to choose, it is up to the owner of the room to decide. For best results, treat the surface with an anti-fungal agent.

And for more information on how to install the second door, you can learn from our training video.

Often this problem also applies to the front doors in private homes. But unlike windows, the problem is not insufficient air convection. What to do if the door is frosted over, condensation and frost form on it?

We note right away that the appearance of condensate mainly concerns metal entrance doors. For them, this is a very urgent problem, wooden doors are less susceptible to it.

Before dealing with the problem of condensation and frost on the front door, let's deal with possible reasons this unpleasant phenomenon.

The first reason for the appearance of condensate on the entrance metal door is quite clear and understandable - a significant difference between the temperature inside the house and outside. If it is -10 °C outside the door, and +23 °C in the house, you will agree how condensation does not appear here.

The thermal conductivity of metal is almost 300 times higher than that of wood. That is why, loved by many, popular metal entrance doors give off heat so quickly. They are cold to the touch, without proper thermal insulation they cannot protect the house from heat loss.

The second reason comes from the first: the doors are simply too thin and not insulated enough. Inside the metal front door there should be a layer that will help it keep warm inside the house and prevent condensation and frost from forming.

Reason three: cold bridges. In addition to the canvas of the metal door itself, cold can be carried out by:

• lock;
• door frame;
• metal ribs.

That is, all the metal parts of the door equipment that pass through the canvas serve as cold bridges. By the way, in a wooden door, the lock can also become a bridge of cold, like a box and fasteners. Therefore, to say that wooden door completely protected from all problems with the appearance of condensate and drizzle is not necessary.

Condensation on the front door is unpleasant in itself, and in addition can cause the following problems - locks and other metal parts will rust under the influence of constant, strong humidity throughout the cold season. Mold can appear on the door slopes, they will turn black, this is unattractive and unhealthy. In addition, a frozen lock is difficult to open.

You can deal with condensation and freezing of the front door in the following ways:

• Order a high-quality, multilayer door with effective insulation and insulation of all cold bridges. Yes, it will cost a lot, you will have to pay for the quality. But on the other hand, there will be no problems with retaining heat inside the house and water leaks on the inside of the door initially.
• Engage in insulation of a low-quality, empty metal door inside. You can use regular foam, but this is not a very effective option. Better choose more modern insulation, which should be laid inside the door. There are specialists who provide such services.
• It is advisable to cover the metal sheet with powder polymers having weather-resistant treatment. It is also possible to finish the outside of the door with impregnated panels special formulations protecting against temperature fluctuations.
• Cold bridges can be dealt with by filling all hollow metal elements with mounting foam. Also, the place where the door frame fits to the door opening is carefully blown out with mounting foam.
• Install insulation tape around the perimeter of the box, it is simply glued to the canvas. The lock can be covered with a special sliding cover - it will not become reliable insulation, but it will block the direct access of cold air for sure.
• Insulate slopes, for example, with foam or mineral wool, and plaster and paint on top.

Most effectively, a vestibule or veranda will protect against condensation on the front door and the appearance of ice. Such a simple walk-through unheated room in front of the house becomes a layer that does not allow the coldest air to get to the front door. And even though it will be cold in the vestibule itself, it will still be warmer than on the street. That is, the temperature difference will be noticeably lower.

For the same reason, another entrance door, additional, helps to get rid of problems with condensate. Inside the house, it is advisable to install another door, preferably wooden or plastic, so that the metal is less exposed to temperature differences. The more layers, the warmer - this principle works not only when dressing in cold weather, but also when warming the house, remember this.
