Rating of TOP-5 entrance doors with thermal break from the manufacturer

To make it easier for you to choose, here is a rating of doors with thermal breaks. This is the optimal solution for installation at the “house/outdoor” border to retain heat indoors.

An excellent option for a summer cottage or as a temporary frost-resistant door for a private home. The outer coating is made of durable powder coating and looks neat and discreet. The inside of the canvas is treated with a practical laminate with imitation of natural wood. Sound and heat insulation is provided by filling with expanded polystyrene, penoplex and isolon. Thermal release material, cork sheet, does not let out warm air and blocks cold air from the street.

A light model without decorative elements will provide reliable protection against unwanted entry and create comfort in your living space. Powder-coated exterior cladding withstands heat and frost. It can be easily cleaned with a damp cloth without fear of scratching. Burglary resistance is provided by two reliable Guardian locks.

Standard sizes, coating color, equipment can be changed upon individual request.

For this price you will receive reliable protection from unwanted intrusion, a comfortable atmosphere in the room, and decoration of the interior and facade.

MDF panels look like solid wood, but are not inferior to it in performance characteristics. Three seals in combination with a thermal break and high-quality fillers allow you to save on heating and underfloor heating. Sealing tapes block not only drafts, but also unnecessary sounds and dust.

A representative and stylish model will emphasize the status of a private home and will be a godsend for those who consider a bathhouse not just a place for water treatments, but a whole ritual for recuperation.

The beautiful finish of dark MDF panels with geometric milling with a glass insert is perfect for a wooden building. Noise and thermal insulation is made with one of the best fillers - mineral slab "ROCKWOOL". This is an environmentally friendly material that does not emit harmful substances when heated.

Elite model, suitable for installation in cottages, theaters, and administrative buildings. Exquisite veneer finish looks representative and stylish.

The optimal steel frame thickness of 1.5 mm provides reliable support for a heavy non-standard door. If necessary, strengthen the walls. The design provides 3 protrusions around the perimeter, but a design with 4 sealing contours is possible.

Glass inserts visually make the model lighter.

"STAL-GROUP" offers production according to your sizes at an affordable price.

External and internal finishing

The external finish of the front door must be resistant to impacts and scratches, and if it goes outside, then, in addition, it must withstand frequent exposure to precipitation and sunlight.

The most popular exterior finishing options:

• Powder coating is obtained by applying special paints to the metal surface, which are baked under high temperature to form a durable, damage-resistant film. The color of the coating can be almost any. Its advantages include low price, strict and laconic appearance, good resistance to precipitation, sunlight, and mechanical damage;
• solid wood is beautiful and expensive. By choosing a specific type of wood and the method of processing it (painting or varnishing, carving), you can obtain the desired appearance of the canvas. Wood has excellent heat and sound insulation qualities. The downside is that it’s easy to leave a scratch on the surface, and besides, wood is afraid of changes in temperature and humidity. In order for the finish to be durable, you will have to regularly treat the wood with protective agents. If the door faces the street, then the treatment will have to be carried out more often, and it is better to have additional protection in the form of a canopy over the entrance to the house;
• MDF panels allow you to perfectly imitate any type of wood, but at the same time they are not so afraid of precipitation and temperature changes. MDF panels are made from wood chips, have a thickness of 7-20 mm, and are covered on top with veneer (a thin cut of natural wood), paint or PVC film with any pattern. The panel can be either absolutely smooth or have a relief, which gives it additional solidity. Most commercially available doors with a thermal break are finished with MDF panels, since this is the optimal combination of price and quality;
• other finishing options (including finishing with vinyl leatherette, plastic panels or PVC film alone) are almost never used in doors with thermal breaks, as they have dubious operational and decorative qualities.

For interior decoration use:

• Powder coating is practical and inexpensive, but many are not satisfied with the too simple type of finish, which, moreover, does not always fit into the interior of the hallway. If the door leads to the vestibule, then this option is more than acceptable;
• wood is an ideal option for interior decoration. And if such cladding is not recommended for ordinary metal doors (condensation will quickly destroy it), then for doors with a thermal break this is a very suitable solution, although it will not be cheap;
• MDF panels will also not suffer from condensation if the canvas is protected by a thermal break, so they are perfect for interior decoration;
• a mirror is usually used only for partial decoration of the door, but in some cases it can completely occupy the entire space of the door leaf. This is a great way to expand the space of a small hallway and save space for other things, because you don’t have to hang a mirror on one of the walls. True, the mirror weighs a lot. Plus, the front door gets dirty quite quickly, so washing the mirror will become almost a daily task.

Qualitative differences between doors with thermal break

Experience shows that entrance doors in homes are often susceptible to aggressive environmental influences. Over time, such door blocks lose a significant share of useful functions, and may even become completely unusable. This is especially true for classic wooden doors, which are very susceptible to water, abnormal temperatures, and are not resistant to parasites such as moss, fungus, and rodents. In winter, such ordinary metal and wooden doors can become covered with frost and ice, which not only worsens the appearance of the door, but also reduces the amount of heat in the room.

Photos of ordinary wooden and metal doors at low temperatures.

In addition, wooden doors burn well, so they are absolutely unreliable in case of fire situations. Quite the opposite can be said about steel doors with a thermal break, which have a number of undeniable advantages:

• good heat and sound insulation;
• absence of freezing and condensation;
• biological inertia;
• fire-resistant properties;
• resistance to UV rays, corrosion, high humidity, temperature changes;
• high resistance to mechanical damage;
• durability;
• universality of application - absolutely everywhere and in any climatic latitudes.

What are thermal break doors?

Today, the use of standard metal entrance doors is associated with a large number of problems. The main disadvantage of such products is that they are not able to prevent heat loss in the home. Thus, cold air accumulates inside the room. To prevent this, manufacturers use different types of insulation (when making a door leaf, a layer of heat-insulating material is laid between the steel sheets of the frame).

Entrance metal doors with a thermal break are insulated structures, the leaf of which contains layers of insulation and special thermal insulating gaskets. It is the latter that have low thermal conductivity. Most often they are polyamide inserts of different thicknesses, located between two insulation materials and in other vulnerable places, reducing heat transfer from one material to another.

On video: doors with a thermal break - what are they and when are they needed?

What is used for thermal break?

Different types of insulation are used as thermal breaks:

• polyvinyl chloride;
• mineral wool;
• Styrofoam;
• cork.

The best are considered to be cork materials, which have excellent heat-saving characteristics and protect the metal sheet from freezing even in the Far North.

As a result, the metal sheets do not warp, are hermetically sealed and do not let cold air into the apartment or country house.

Recommendations for selection

When choosing an iron entrance door with a thermal break for a country house, do not forget about the purpose and requirements for this type of product:

Such doors are not intended for indoor use (such a solution does not provide any rational or aesthetic benefits).

High-quality models must be made of steel sheets with a thickness of at least 2 mm. This metal protects the rupture zone during severe cold and heavy precipitation.

The standard width of the canvas is 860 mm, it is better to choose a thickness of up to 100 mm. If necessary, you can order a door according to individual parameters, the craftsmen will make it in a short time, having agreed with you on the material and type of insulation.

For reliable fastening and long-term operation, such doors must be equipped with strong hinges, a reliable locking mechanism and high-quality fittings.

It is preferable to choose models with levers for fixing the leaf in the door frame. This will increase the degree of protection against hacking.

Thermal doors are an excellent option for a private home or cottage. They look great with any design of a living space, are reliable, practical, durable and, most importantly, protect from cold weather, strong winds and extraneous noise.

The choice of such a door design should be approached with special responsibility. Before purchasing, be sure to check the quality certificate for the product, study the technical characteristics and dimensions. It would be a good idea to read customer reviews about products from different manufacturers. This will allow you not only to choose the best model, but also save a small amount of money.

Know-how technology at your doorstep

The secret to the quality of doors with a thermal break lies in the unique production technology of the door block.

This technology was developed to improve the quality of living conditions in climatic latitudes with abnormal temperature and atmospheric phenomena. In 2000, doors with thermal breaks gained popularity, and to this day the demand for these models is growing rapidly. This technology consists of a unique method of filling the space with heat-insulating materials between 2 steel door leaves. This technology prevents heat loss and condensation on the inside of the door block.

Materials used for the manufacture of thermal doors

The following materials are used in the production of standard doors with thermal break:

• sheet steel for boxes and panels;
• foil-coated isolon as insulation for the frame;
• penoplex, foil, polystyrene foam as insulation for the canvas;
• cork sheet, isolon and penoplex for thermal break.
• All doors are equipped with high-quality and beautiful fittings.

The use of such materials can significantly reduce the influence of low temperatures on the structure, and thermal break allows you to almost completely block heat loss due to the impossibility of contact between high and low temperatures. As you can see, the materials used are quite common and inexpensive, but it is their correct location inside the door structure that makes such a barrier an excellent way to insulate your home.

What are quality models made of?

Getting acquainted with the rating of entrance doors with a thermal break will help you get an idea of ​​what such products should be like. The best of the best are designs that include:

1. several layers of insulation made of materials with different levels of heat transfer. Thus, stone and mineral wool, foiled polyethylene foam, and polyurethane foam are combined in one fabric. Not only the sash, but also the frame is filled with insulating materials;
2. the actual effect of a thermal barrier, when direct contact between the external and internal metal parts of the block is completely eliminated;
3. seals that equip the canvas and frame;
4. decorative panels made of solid wood or MDF, forming an additional “line of protection” on the path of cold air.

Installation of doors with thermal break

Long-term and comfortable operation of the door largely depends on correct installation. When installing the door system, you should avoid distortions of the frame, strictly maintain the gaps recommended by the manufacturer and adhere to the instructions. Only then can a door with a thermal break cope with the tasks assigned to it. The basic algorithm of actions looks like this.

1. Before installing the frame in the opening, remove the door leaf from its hinges. To do this, open the door and lift it up.
2. To prevent freezing of the door and the appearance of condensation, fill the internal cavities of the box with polyurethane foam.
3. After the foam has completely dried, you can begin installation. Place the box in the opening so that the platband is pressed tightly around the perimeter.
4. Adjust the position vertically and horizontally using mounting pads and wedges.
5. To adjust the position, use a mounting level or plumb bob.
6. If it deviates from the vertical, do not press the box against the wall with great force so as not to deform it.
7. The permissible deviation from the vertical and horizontal plane is 1.5 mm/1 m or no more than 3 mm over the entire length.
8. If there are deviations of the posts in different directions (twisting effect), the total tolerance does not exceed 3 mm.
9. An installation gap of at least 20 mm must be maintained between the threshold and the floor.
10. Drill through the mounting holes in the box for installation of fastening hardware. These can be anchor bolts, dowels, concrete screws.
11. Carefully check the position of the door frame in different planes and secure, starting from the side where the hinges are located.
12. Place gaskets in the gaps between the wall and the embedded element to prevent deformation when tightening the fasteners.
13. Fill the installation gaps with foam, after moistening the wall surface with water from a spray bottle. It is better to start filling from the threshold and gradually move from bottom to top.
14. After hardening, remove the spacer wedges and cut off excess dried foam with a knife.
15. Hang the door leaf and leave the door open.
16. Install door hardware.
17. Check the tightness of the closure using the handle.
18. If necessary, adjust the position of the rebate.
19. Ideally, the door closes easily with a slight push forward. There are no gaps between the canvas and the box.

If you doubt the result, then you should not take the risk and do the installation yourself. It is better to seek help from professionals.

What is thermal break? Door design with thermal break

Doors with a thermal break are a very simple and at the same time ingenious invention. The design is based on physical laws. To prevent heat transfer into the door, it is necessary to prevent contact between the two metal parts of the door, and this can be done by using a layer of material with low thermal conductivity. This material, in essence, is a thermal break. This insert is placed between the insulation layer and the metal frame (visible in the image). Design details may vary slightly.

Thermal break allows you to completely eliminate heat leakage from the room, and also forget about the formation of condensation and ice, because the inside of the canvas will not be cooled. A similar result can only be achieved by using a double door, where the air gap plays the role of a thermal break.

Thermal explosion is carried out, as a rule, from polymer materials, less often - from wood. The thickness of the insert may vary. Manufacturers do not hide that such a system remains effective at a temperature difference of no more than 40C. With more significant differences, even doors with a thermal break can “cry”, but, of course, not to the same extent as ordinary metal doors.

Everything else about doors with a thermal break is the same as in ordinary metal doors:

• outer and inner steel sheet 3 mm thick (2 mm is possible, but this is a less safe option). Doors made of too thin steel, although they are cheaper, can be opened almost with a can opener, and even the coolest lock will not save you. Sometimes the internal panel is made of MDF, which makes the design cheaper, but its burglar-resistant qualities will also be lower;
• metal door frame made from a single profile pipe or several parts;
• Stiffening ribs strengthen the structure and act as its skeleton. At least there should be one horizontal and two vertical ribs, but the more, the better;
• insulation fills the voids between the stiffeners;
• the door design also provides for the presence of a seal, and the door itself is installed in the door frame and is held on it by hinges;
• the lock ensures security; in some doors it is additionally protected by a metal plate;
• handle, hinges and eyelet.

When they talk about the thermal break of doors, they usually mean the thermal break of the door leaf, i.e. element that isolates one outer part of the metal from the inner one. However, high-quality doors also have a thermal break in the stiffeners and a thermal break in the frame.

Advantages and disadvantages of doors with thermal break

Doors for your home with a thermal break allow you to retain heat even at temperatures outside the window below -30 degrees. Also, canvases have other pros and cons.

Tambour or door with a thermal break for a cottage?

Entrance doors to a house with a thermal break can be single-leaf or double-leaf, with different types of insulation. The cheapest options are with sheet steel 1.2 - 2 mm thick, the middle class has steel - 2-3 mm, premium - 4-5 mm. Thermal doors are also divided into metal, plastic, aluminum. As an alternative to street doors with a thermal break, you can build a vestibule or make two doors, the air between which will act as a thermal break. But these techniques have their drawbacks. The cost of building a vestibule plus installing a cheaper door leaf will be no lower than buying a good insulated door with a thermal break, or even more. The same applies to the installation of double doors. There is another added inconvenience - when entering/exiting, you need to open two doors.

It is worth thinking about a vestibule if the entrance is located on the north side. Because when opened, cold air rushes into the house, which is not pleasant. The same applies if a large family lives in the house, whose members regularly go to work, school, or other matters. Another option when you should prefer a vestibule is if there are several adjacent rooms to it, for example, on one side the entrance to the house, on the other to the garage, utility block.

Outdoor insulated doors with thermal break

When planning to buy a steel door with a thermal break, do not reduce the importance of other methods, which, together with modern technology, can make your home a real oasis of comfort and coziness

These methods of thermal insulation include seals used to connect the sash more closely to the frame. There is a wide range of materials with an adhesive and magnetic base, which are attached along the perimeter of the canvas in one, two or three rows (the third row is applied directly to the box). Thanks to this, the sash closes almost silently, does not allow drafts and street noise to pass through, and prevents heat loss, so that during operation you will be completely protected from the unpleasant effects of cold weather.

Magnetic seals are the most modern means of protecting your home from drafts and dampness. They are strips of elastic material placed in a frame with a magnetic insert, which ensures the attraction of the steel leaf even if the door was not initially closed tightly. The triple sealing contour involves placing an adhesive or magnetic strip not only around the perimeter of the leaf, but also at the junction of the sash with the frame. Such an addition to the package will help extend the service life of the product, as well as achieve the maximum level of insulation of the structure as a whole.

Insulation of the box involves the use of a special layer of polystyrene foam, expanded polystyrene, mineral wool or mineral wool slabs. The principle of operation of thermal insulation materials is based on creating obstacles to the movement of cold air inside the sheet. For this purpose, the cavity between two sheets of steel is filled with inserts of material having a porous or fibrous structure inside.

When choosing this or that insulation, pay attention to its performance and physical characteristics. Thus, mineral wool slabs have a long service life, but have significant weight

And light glass wool, with a significant increase in ambient temperature, can release harmful substances.

Prices for doors with thermal break

The price of doors with a thermal break in Moscow varies widely. The cost depends on the number of layers of insulation and the materials used for it, design features, and finishing. Budget door leaves can be bought for 20,000 - 25,000 rubles. Business class products cost 40,000 – 60,000 rubles. You can buy premium doors with a thermal break at prices ranging from 80,000 to 200,000 rubles.

Note that the initial price of the manufacturer in the process of repurchase and subsequent resale increases significantly. Therefore, you need to buy products from those stores that cooperate with manufacturers directly, like. We work without advance payment. Prices are fixed and do not increase after placing an order, as is the case in many other online stores. You can buy doors from Thermo (Bravo), Argus and other reliable manufacturers without overpayments.

Thermal break in metal doors: what is it and how does it work

The operating principle of such structures is based on the use of special insulating layers - they level out temperature differences. Thermal break is ensured by inserting an intermediate layer of material with poor thermal conductivity into the canvas or box. Typically, this is a polymer insert that runs between two insulating materials, one with high thermal conductivity.

Structure and location of heat insulators in doors with a thermal break

The thermal break prevents the door from overheating or hypothermia, creating a comfortable room temperature even when it is overcooled or overheated. The thermal break is installed around the entire perimeter of the door.

Which products are considered the best?

At the boundary with the street, models with standard insulation are not always as effective as we would like. An excellent barrier to heat loss is created when two doors are installed one behind the other at the entrance. But the size of the room and finances sometimes do not allow organizing a vestibule. Outdoor doors with thermal breaks occupy high positions in the rating if:

• slow down the heat exchange between the hallway and the external environment. On frosty days, the canvas remains cold on the outside and warm on the inside;
• don't "cry". The interior decoration of the structure is unharmed and attractive, since water does not accumulate on it, which can cause rotting, swelling of the wood and other negative phenomena;
• don't freeze. There is no condensation, which means there is no frost or ice crust on the product. There is no piercing cold from the passage in winter.

The rating of outdoor insulated doors with a thermal break for the home includes solutions that cannot boast of very low prices. However, thanks to them, significant savings are achieved. Firstly, heating costs are reduced. Secondly, the need to purchase a second block and install a vestibule disappears. Thirdly, household members get sick less often, which, of course, is a plus not only from a financial point of view.

What is thermal insulation made from?

As a rule, when producing thermal insulation, manufacturers use polystyrene foam, polyvinyl chloride, and mineral wool. Or a completely new lightweight material, izolon. They provide not only thermal protection, but also the tightness of the door leaf. Which can create a reliable barrier to twenty-five degree frost.

But when buying a door, check with the seller to see if fiberglass was used in the production. The fact is that at elevated temperatures, it releases harmful substances. If you live in an area with hot summers, then it is better to refrain from such a purchase. In regions with a temperate climate that does not suffer from heat, such a door will be safe.

Manufacturers use wood to make the most environmentally friendly break doors. Undoubtedly, wood has excellent thermal insulation. However, such doors are quite expensive. Not every consumer will be able to afford them.

Domestic door manufacturers

There are two main tricks that can prevent you from choosing a good door. The first is the belief that foreign goods are better. This opinion is very wrong, because the success of local companies rests precisely on quality, demand and good reviews. And the competition for domestic factories is not easy - you constantly need to develop something new and immediately implement it into the technical process. The second wrong idea is to choose a door at the lowest cost. The door design itself with a thermal break has several layers of expensive materials, so the finished product, in principle, cannot cost little. One conclusion can be drawn - it is better to choose a Russian manufacturer. True, there are quite a few of them, and it’s easy to get confused.

Materials for arranging a thermal break

Thermal break can be made from different materials, which naturally affects the performance characteristics of the canvas. Among the most common materials we note:

• PVC is the most budget option, but also the least practical, as it can hardly withstand frost and at temperatures below -250C loses its performance qualities;
• wood is the direct opposite of PVC. It is expensive, but works most effectively as a thermal break. As a rule, oak inserts are used, but there are also models with cork inserts;
• fiberglass perfectly insulates metal parts, but when heated it can release toxic substances, therefore it is not recommended for use in residential premises;
• basalt wool and polystyrene foam are optimal materials in terms of performance and price, a combination of which is used in most modern doors.

Please note that a thermal break can be achieved not only by inserting the appropriate material or attaching it to self-tapping screws and bolt-nuts (which is done in most cases), but also by creating micro-cuts in the box and canvas. Theoretically, if you violate the integrity of the metal, you will be able to break the cold bridges

In practice, micro-incisions are made using a laser, and they do not eliminate the formation of cold bridges, but only reduce their area. Reviews indicate the low effectiveness of this solution, so we will not recommend it.

Dimensions of steel doors with thermal break

Door sizes depend on the specific manufacturer. You can choose a door system with a leaf width of 0.86-1 m. The height can be 2-2.5 m.

It is possible to order an individual door on special order - for example, with carved forging

Important! In such models, the width of the sash can reach 7 cm or more.

Doors with a thermal break for a private house

The most popular models are those with a thermal break for installation in a private home, since in this case the hallway is directly adjacent to the street. Installing a metal door with a thermal break completely eliminates the occurrence of such negative consequences of cold weather as the formation of condensation and ice on the inner surface.

High-quality insulation of the entrance allows you to significantly save on heating, which in country apartments is of particular importance for the homeowner: the heating systems used can be adjusted, giving them less load, so that fuel and energy costs will be significantly reduced. Thanks to this, the purchase of an expensive model with a thermal break pays for itself within the first two to three years of operation.

However, modern manufacturers offer a fairly wide range of models that are manufactured using various components. The buyer has the opportunity to choose a product that is optimal in terms of financial costs, with decent thermal insulation qualities.

You can reduce the price by choosing a design with inexpensive finishing and fittings: even affordable materials (laminate, powder coating) can become the basis for creating a beautiful and durable entrance door.

By installing a metal entrance door with a thermal break, you can significantly reduce the cost of heating your home, because the efficiency of heat conservation increases. This benefit will be especially beneficial for homes that are heated by electricity.

Thermal doors not only minimize heat loss, but also have a significant level of sound insulation

Let's consider the characteristics and advantages of outdoor entrance doors with a thermal break:

• profitability due to reduced heating costs;
• reliable assembly system;
• ease of operation;
• high quality coating;
• resistance to the appearance of frost and ice;
• eliminates the possibility of condensation formation;
• high level of sound insulation;
• high degree of fire safety;
• endurance to the influence of low temperatures.

Despite the large number of advantages, steel doors with thermal breaks also have disadvantages. The presence of all the above benefits depends on several conditions that must be adhered to. Firstly, if the operating conditions of the doors are accompanied by high humidity, there will be a risk of ice formation. To avoid this, you will need to organize a supply and exhaust ventilation system.

Entrance doors with a thermal break have a rather heavy structure, so the builder will take care of periodic lubrication of the hinges

Secondly, entrance doors for a country house with a thermal break put forward increased demands regarding the quality of installation work. Slope, skew, deformation changes in the canvas - any error made during installation can negate the thermal insulation qualities of the structure.

Thirdly, you will definitely need to buy handles with a similar function as additional equipment for the front door with a thermal break. Conventional fittings will serve as a source of heat leakage.

Characteristics of materials for insulated entrance doors

When choosing a product, it is advisable to pay attention to the quality and features of the thermal insulation material. The frame of reliable structures is made of thick sheet steel. At the same time, the width remains standard - about 86 cm. Steel has more advantageous characteristics than PVC or wood.

High-quality thermal doors are left with a thermal break not only in the door leaf, but also in the frame

There are products made from thin steel on sale. You should not buy into the low price and light weight of such doors as they are very easy to open. To do this, just use a can opener. It is desirable that there is reinforcement on the canvas. A door with this design will be more difficult to break into.

Note! If there are steel sheets on both sides of the door, then before purchasing the door you should check their integrity and make sure there are no holes. As a rule, the thickness of this material is 1.8 mm.

Most entrance doors with a thermal break for a private home have a heavy structure, which cannot but affect their performance and service life. To extend the period of effective use of the product, it must be equipped with reliable and durable hinges. Standard fixing elements are not suitable for these purposes. The best option would be special levers that secure the canvas in a stable position.

It is worth considering that an important nuance when installing doors with a thermal break is the correct installation of the frame and insulation of the seams

What is a thermal break?

This is an insulation layer, a paronite gasket that performs a protective function and lies between the panels of the device and at the junction points of the box, during the assembly of which paronite washers are used. Tightness is achieved through rivets using a bolted connection. Polyvinyl chloride, isolite or mineral wool are also widely used. Insulation with the above materials can create a thermal break of up to 25 degrees. When using fiberglass, you must remember that at high temperatures, this item releases harmful compounds into the air. When using such an interlayer, it is necessary to take into account climatic conditions and production characteristics. Thermal conductivity of steel is 58 W/NS. Paronita – 04.4 W/N.S. This is 145 times lower than steel, but it provides a full opportunity to cut off temperature differences along the entire perimeter of the structure, and most importantly reduces vibration and structural noise.

Thanks to this layer, the temperature difference between the street and the interior is smoothed to a minimum.

The interlayer liner, paronite, is by far the best composition that is not afraid of dampness, temperature and pressure differences. Visually, you can observe a flexible, spacer sheet, often used as a seal. Made from asbestos, rubber and other mineral compounds.

Thermal rupture is a good solution for metallurgical facilities, engineering enterprises, chemical and oil industries, namely production sites exposed to high temperatures and pressure.

When releasing this type of addition, they are guided by the laws of physics. The main task is to prevent a quick meeting of cold from the street and heat coming from the room.

An illiterate approach to purchasing can lead to additional problems related to the quality of operation.

An unscrupulous manufacturer or seller, in order to sell a more expensive product, recommends a design whose backing is made of balsa wood or solid wood. It is an excellent heat insulator and a good sealant. It also has a high price due to the high cost of the natural material, but it has poor moisture resistance, is more susceptible to freezing and is not applicable for the manufacture of washers for breaking bolted joints.

Criteria for choosing a door with a thermal break

When purchasing a door with a thermal break, you should additionally consider the following nuances:

• Canvas dimensions. This parameter depends on the size of the doorway. As for the door thickness, this parameter should be selected based on operating conditions. In harsh climates, it is advisable to opt for a thicker door structure.
• Design features of thermal break. It is desirable that the thermal break be an independent structural element that does not require the use of bolts or self-tapping screws for fixation. Otherwise, there is a risk of “cold bridges” appearing.
• Country of origin. It is recommended to give preference to domestic doors. Compared to cheaper Chinese counterparts, they are distinguished by high quality, excellent design and long service life. Before purchasing, you should definitely study the product passport, which should indicate all the most important characteristics.

It remains to add that installing doors with a thermal break is a rather complex task that requires the involvement of professionals.
