Is it possible to apply infrared film under the tiles? Installing an infrared film floor under tiles: is it worth it? Types of heated floors

Tile and porcelain tiles are very practical materials, but they are cold for walking barefoot. The underfloor heating system solves this problem and also provides additional heating to the room. At first glance, an infrared heated floor under tiles is best suited, since it has the thinnest heating elements. But in fact, the film creates more problems than the benefits when laying in tile adhesive. In this article we will look at how you can install infrared floor heating with your own hands.

Is it possible to lay film flooring under tiles?

Infrared heated floors are intended primarily for “dry” installation under laminate, linoleum, PVC tiles, and carpet. To attract customers, many manufacturers claim that their film can be laid in screed or tile adhesive under the tiles.

There are 3 main reasons why you shouldn't do this:

• Firstly, the film has low adhesion. If you immediately pour screed on it or lay tiles, it will turn out to be floating. Because of this, the concrete will have a hollow sound when tapped, and if something heavy is dropped on the floor, the screed may even crack.

Sometimes for better adhesion of the solution with top layer trying to make a lot of cuts and serifs. But imagine how difficult it will be to isolate it all. Moreover, you need to insulate it reliably and durablely, so as not to break the tiles if you start receiving electric shock from leaks and the RCD constantly trips.

• Secondly, the composition of the film itself. All tile adhesives and screed solutions are alkaline. Over time, polyester film (PET) corrodes, regardless of the thickness or number of layers. IN best case scenario you will get short circuits and sparking from exposed electrical connections.
• Third, there are rod and cable electric floors that are ideal for under-tile installation. When installing them, you don’t need to invent or invent anything; they are specially made for “wet” installation.

But there are several installation options, which are discussed below.

Necessary materials

The standard installation kit should include:

• Thermal film in a roll;
• Contact clamps;
• Set of wires;
• Bitumen insulation on a self-adhesive basis.

Additionally you will need to buy:

• Thermal reflective insulation;
• Heat-resistant polyethylene film;
• Thermostat and mounting box for it. It is selected based on the selected power of the heated floor and the type of installation (built-in or surface-mounted);
• Additional temperature sensor if necessary (one will be included with the thermostat);
• Double sided tape;
• Additional wire for mounting a thermostat. It may also be needed if you install several sets of heated floors in one room (you will need to add up their power to calculate the cross-section). The wire cross-section is selected depending on the power of the system and the material of the purchased wire (see table).

Installation stages

Preparation

Do not place heating elements under low furniture. Above the floor must be carried out good ventilation and leave a gap of at least 3 cm.

To guide thermal energy up and reduce electricity consumption, heat-reflecting insulation should be laid under the heating element. You can use materials coated with metallized Mylar or polypropylene film, but it is prohibited to use insulation based on aluminum foil, as it corrodes over time.

• Select in advance the installation location of the thermostat on the wall and install the wiring there.
• Determine the areas on which the film heated floor will lie.
• Prepare a clean and level base.
• Place heat reflective material on the floor. It is best to lay it over the entire area of ​​the room, and not just under the film, so as not to create unnecessary unevenness. Secure it with tape to the base and glue the joints.

Installation of thermal film

• Roll out a roll of thermal film on the floor. Along specially marked lines or between black silicon strips, you can cut the roll under required sizes. The copper contacts should be side down.

It is better to cut the film into pieces of the maximum permissible length in order to reduce the number of contacts. To reduce wire consumption, the contacts of the film should extend towards the thermostat.

• Attach a clamp to the copper strip. One side of it should be inside the thermal film, and the other side should be outside on top of the copper strip. To fix it, clamp it with pliers.
• Seal the cut lines with bitumen insulation. If the cut was not made along special lines, you need to isolate the entire side completely.
• Secure the thermal film with tape so that it does not accidentally move.

Connection

Laying tiles

Methods for laying tiles on film

• The first is that a plaster (painting) mesh is fixed over the polyethylene waterproofing to increase adhesion. A screed or self-leveling mixture with a thickness of 8-10 mm is poured onto it.
• The second is that the floor is sheathed with gypsum fiber sheets (gypsum fiber sheets) on top of the waterproofing. They are attached to the base with self-tapping screws between the strips of heating elements. This must be done very carefully so as not to damage them; retreat at least 6-10 mm. If the area is small, then you can first attach the film to the wrong side of the gypsum fiber board, and then lay it on the floor.

Conclusion

After this, the tiles are laid using conventional technology, which has been repeatedly described on our website. The only difference is that you need to use a special elastic adhesive for heated floors and observe temperature gaps. In order not to forget later where you can drill holes in the floor, draw a plan diagram with the location of the heating elements and cables.

Let's try to answer actual question, asked to us by clients who, before visiting our Center, read a number of articles on sites selling infrared film heated floors.
In light of South Korean expansion, there has been a significant increase in the number of new dealers offering infrared film (heating material) different designs. The use of film is offered always, everywhere and anywhere. At the same time, sellers are not embarrassed by either building codes, neither electrical safety standards, nor even the laws of physics. Among other things, it is proposed to use IR film under ceramic tiles.

Let's discard everything right away miraculous properties IR films. This is air ionization!!!, anti-allergenic effect???, neutralization of odors))), reduction in the level of electromagnetic fields, increased efficiency, etc. Well, the main feature is, of course, fantastically low energy consumption.
The film placed under the tile is nothing more than a thin heating element that transfers heat to the tile using HEAT TRANSFER. Because infrared (IR) rays do not penetrate through cement-sand screed, tile adhesive and the tile itself. In general, there are very few opaque materials that transmit IR rays. For example, silicon crystals...
So what we have is a hot film that only heats the materials in contact with it, which in turn transfers heat to the tile. In this case, efficiency is the percentage of conversion electrical energy the film's thermal performance is the same as any other electric heater- close to 100%. And to warm up flooring before comfortable temperature, any type of electric underfloor heating - thin mats, infrared film and heating cables - will spend approximately the same amount of watt/hour of electricity.

Now let's look at the options for laying film under the tiles.
1. Option KNAUF "Super sex"
Knauf Superfloor is a factory-made floor element glued together from two small-format moisture-resistant gypsum fiber sheets measuring 1500x500x10 mm offset relative to each other in two perpendicular directions by 50 mm. Total thickness - 20mm. Structures using KNAUF Superfloor are used for constructing foundations underfinishing coatings on both reinforced concrete and wooden floors. They are suitable for any type of modern floor coverings (linoleum, parquet, ceramic tiles, etc.). Laying the covering can begin immediately after the glue used to connect the floor elements to each other has dried. For gluing floor elements during installation, adhesives supplied by KNAUF group companies are used. Before the glue hardens, secure fixation is performed with gypsum plasterboard screws.
In our case Heat Plus - infrared film, and dry backfill - expanded clay, can be replaced with polystyrene foam boards.
There is a danger of damage to the film by excessively twisted screws and difficulties when installing the film over large areas. In addition, inaccessible handmade connections between pieces of film remain out of reach.

Option 2 when a sheet of SML, DSP, GVL is laid on top of the film.
Offered by many film flooring sellers.

This installation option has problems with reliable fixation of sheet protective material. When fixing with self-tapping screws, you can get into the current-carrying paths of the film and also disrupt the waterproofing of the room.

3. Option with film filling directly with a screed or glue we mark it as verified incorrect.

Conclusion

What do we have as a result? There is one plus of infrared film for tiles -the price of the film itself . Classic striped film has this advantage. Multilayer films with a continuous carbon layer are many times more expensive.

There are few minuses but...
1. Less reliability compared to classic factory-assembled cable systems. The weakest point is the connection of the current-carrying busbars with power wires done on the spot by hand
2. Complicating the floor structure due to additional layers and, accordingly, its rise in price.
3. Electrical safety. The film is intended for use in dry rooms. Grounded film exists, but is more expensive than the classic thin shielded heating mat designed for installation under tiles. In addition to all this, heating films are unshielded, so why do you need extra electromagnetic background under your feet?
4. Moisture resistance. The places where the film is connected to the supply wire are not sealed, which means that if the pipe breaks, moisture can simply short-circuit the entire system, or the phase voltage will appear on the surface of the tile.

Tile and porcelain tiles are excellent materials for flooring - durable and practical. The only disadvantage of tile floors is the heat transfer coefficient.

Ceramics are not able to accumulate heat and immediately release it environment, so tile floors always feel cold to the touch.

If in summer heat This feature can still be considered as a plus, but in the cold season the feeling of a cold floor creates a certain discomfort. Correct the situation and do tiled surface Not only practical, but also comfortable, a heated film floor under tiles will help.

Features of the operation of film heated floors

Film floors require minimal energy costs

Warm floors are a relatively new type of space heating, successfully used in both residential and public buildings. Their main difference from the classical heating method is the placement of heating elements not on the walls of the room, but directly under the floor covering. This makes it possible to create the most comfortable temperature in the lower part of the room with a minimum of energy costs.

Among all types of floor heating systems, infrared floors are the most technologically advanced to use.

1. Compared to cable systems, IR flooring has a higher coefficient useful action(efficiency).
2. Unlike water floors, IR systems do not use a liquid coolant, so the possibility of leaks is excluded.
3. IR systems emit almost no electromagnetic waves during operation and do not dry the air.

The table shows the comparative characteristics of infrared floors and water underfloor heating systems.

The effect of infrared waves is similar to the effect of sunlight

Heat transfer occurs here through infrared radiation, resulting in heating of the floor covering, as well as objects in the room.

The length of the IR wave is about 10 - 20 microns, which brings its action closer to the sun's rays: freely passing through the air, when it hits walls, ceilings, furniture, etc., it transfers its thermal energy to them.

In turn, the heated objects begin to transfer heat to the air in the room, heating it. This property in thermodynamics is called the effect of secondary convection.

However, like any heating system, infrared floors also have their disadvantages.

Tiles and underfloor heating systems

Warm floors are always covered with a finishing coating on top. IN Lately On the market finishing materials there is a huge number of the most different materials intended for these purposes.

Laminate, linoleum, carpet, parquet board– all these materials look great in any interior due to their excellent aesthetic properties, but when choosing a floor covering for a heated floor, you should be guided by slightly different criteria.

Criteria for choosing a finishing coating

When laying laminate flooring on an infrared floor, it is recommended to lay an underlay

First of all, you should pay attention to the thermal conductivity coefficient of the material. With the classic method of heating a home, when heating is done by wall radiators, the floors are the coldest part of the room, therefore most floor coverings have reduced thermal conductivity.

To protect our feet from the cold, a thermal insulation substrate is laid under the laminate, and inner part linoleum is covered with pile, etc. But what is good with wall heating is a big disadvantage with floor heating. Coatings with a heat-insulating effect block the free transfer of heat from heating elements to the surrounding air.

Tile covering does not have thermal protection

The only type of flooring that does not have thermal protection properties is tile flooring.

A floor covered with tiles practically does not retain heat, which significantly increases the efficiency of floor heating systems.

The tiles are usually laid on a concrete sub-base using a special tile adhesive.

This makes ceramics an excellent option for installing decorative flooring over warm floors. However, this does not apply to IR floors.

Installation of an infrared heated floor under tiles can be accompanied by a number of problems, both directly during the work and during its operation.

Tiles and IR floors - possible pitfalls

There are no problems when laying tiles on water or cable floors

Is it possible to lay infrared heated floors under tiles? Even experts do not have a definite answer to this question. While some people categorically do not recommend installing an infrared floor under tiles, others don’t see anything wrong with it.

Let's try to figure it out possible problems from the point of view of the features of installation of tiles and IR heating systems.

Laying tiles It is usually done on top of a layer of concrete screed. The surface of the subfloors is leveled with cement mortar.

In the case of water floors, it is optimal to fill them concrete screed

In cases with the installation of water or cable heated floors, pouring a concrete screed occurs without problems - such heating structures are recommended to be installed under concrete pouring. In this case, the fill performs three functions at once:

1. Leveling. Makes the floor surface smooth in the horizontal plane.
2. Protective. Protects heating elements – plastic pipes and insulating braiding of cables - from external physical influence.
3. Heat transfer. Concrete pouring is an excellent conductor of heat, quickly and fully releasing it to the surrounding air.

However, with IR emitters the situation is not so simple: it is impossible to screed over a film floor under tiles. Firstly, the compositions tile adhesives and screed mixtures have an alkaline environment, therefore, when the solution is directly applied to the film of heating elements, it may become unusable over time, and those contained inside it electric wires close

Secondly, a concrete screed applied directly to the film will not be able to form a strong adhesion with it due to the low adhesion of the smooth surface. As a result, the screed, which does not have a strong connection with the base of the floors, can simply crack and crumble under the weight of furniture or people moving around the room.

Warm water and cable floors are intended for pouring screeds. Infrared systems should be installed under a screed only in exceptional cases when there is simply no other alternative.

Despite all the prohibitions, nothing is impossible for real masters.

Currently, at least two main methods have been developed for laying tiles over a film heating coating.

One of the installation methods is called “dry” due to the fact that the IR heating elements in this case do not come into contact with the concrete screed. The second method is “wet”. In this case, the concrete solution is poured over the heating structure.

"Dry" method

It is recommended to lay it on top of the IR film protective film and sheets of plasterboard or MDF

The dry method of installing infrared heated floors under tiles involves the following stages of work.

Also, you should not place heating elements under low furniture - cabinets, chests of drawers, sofas. The lack of air circulation over IR floors will sharply reduce their effectiveness, and furniture may dry out and crack due to constant exposure to IR rays.

"Wet" method

This method saves money and resources

The next method, called “wet”, is simpler and faster. Thus, the financial and time costs for its installation are on average 20 - 30% lower than with “dry” technology, but at the same time, installation of an infrared heated floor under tiles is less safe due to possible contact of heating elements with cement mortar.

“Wet” installation consists of the following stages:

As we see, provided correct implementation works, it is quite possible to install warm infrared floors under tiles.

Currently, there are many ways to make your room more comfortable and functional. Heating the room plays an important role in creating comfort. How to properly install an infrared heated floor under a tile, and what is needed for this, will be discussed in our article.

Owners can choose one of the following types of heating:

• water heating;
• film heating system;
• heating using heating mats.

Advantages of heated floors

Below we will look at perhaps the simplest heated floor - IR flooring under tiles.

Its advantages are as follows:

1. The air in the room does not lose its freshness, because this type of heating does not affect it in any way.
2. Infrared heated floor under tiles, emitting waves long length, heats not only the surface of the floor itself, but also the entire body of the person who is currently walking on it.
3. This method of heat transfer allows it to be re-released from previously heated objects, which increases the overall temperature in the room even more.
4. The content of negative ions in the air increases at least 4 times.
5. During operation, infrared film does not emit dust, noise or vibration.
6. The amount of electromagnetic radiation generated is so small that it can be neglected.
7. This type of heating is perceived much more pleasant by humans during the initial low temperatures in the room than in the case of water heating.

So what is a film infrared heated floor laid under the tiles? By and large, infrared heating consists of a thin film 0.3-1 mm thick, equipped inside with an electrically conductive element. Below we will describe methods for installing infrared heated floors under tiles.

Definition with materials and tools

In order to install a film heated floor under the tiles, you will need to acquire the following materials:

• heat-reflecting substrate;
• infrared heating system;
• special dielectric mounting mesh;
• connecting wires;
• flooring, in in this case ceramic tile;
• adhesive mixture.

Laying a film heated floor under the tiles begins with preparing the rough base, which includes eliminating unevenness, cleaning, washing and drying the base. After this, the heat-repellent material is installed.

A layer of infrared film is carefully placed on top. She it's already underway V assembled form, all that remains is to spread it parallel to the heat reflector sheets. Be careful that the film is not overlapped. Otherwise, it may cause a short circuit or deterioration of the heat reflecting material.

Thermostat

The thermostat is a device for controlling the infrared floor system. Its installation is carried out in a predetermined place, and it is connected to the conductive film.

In order for temperature sensors to show correct data, they should be mounted between two layers of screed after placing a corrugated tube. After this, the temperature sensor and thermostat should be coordinated.

Heat-repellent material

Such materials come in several varieties:

• foil;
• cork;
• with a reflective surface.

Everyone selects the type of insulation based on their needs.

Electrically conductive wire

Laying an infrared heated floor under the tiles is accompanied by laying a wire running from the temperature sensor to the temperature controller. This is a fairly easy process - the wire is connected to the temperature sensor at the end of the corrugated pipe and stretches to the wall on which the control panel for the infrared floor system is located.

The wire will also need to be insulated, making sure that the tie does not get on it.

Preparatory work on the surface

The following work will be required:

1. Remove old flooring.
2. Remove roughness from the base and clean it from dust.
3. Dry the base thoroughly.

After completing these steps, you can begin the main work.

Laying the heat-insulating layer

It is worth noting that the thermal insulation should be laid with the metallized layer facing up. The thickness of the material, as a rule, should be no more than 2-3 mm.

Laying thermal film

Handle this type of material very carefully, as the film is very thin and can be easily damaged. More information about correct installation and safety precautions can be found in the attached instructions. In addition, you should not forget about high-quality insulation of joints after cutting the film!

• Do not lay the film over the entire area of ​​the room. It is better to place it closer to the center, where practically no furniture will be installed.
• If it is intended to lay infrared thermal film under large furniture, you need to think about quality ventilation.
• Allow a gap of 10 cm between the film and the wall.
• Make sure that the thermal insulation is truly dielectric.
• If you lay the film throughout the room, you can save on wiring.

Connection

Before you start laying tiles, you should connect the heated floor and make sure that the system is functioning properly. This way, if flaws are found, it will be easier to eliminate them.

Laying the finishing coating

Now you can install the tiles. The process of laying tiles can be carried out in the traditional way. It will be possible to use the heated floor system only after one month has passed after the completion of laying the ceramic tiles.

Finally

In conclusion, here are a few rules on how to properly use IR heated floors under tiles:

• You cannot install heated floors in any room at temperatures below zero.
• Be sure to provide grounding for the IR film.
• Waterproofing a heated floor, if necessary, should be considered in advance.
• Try not to damage the film; if this happens, insulate the damaged area with tape on both sides.
• The length of the film should not exceed 15 meters.
• You cannot install heated floors under any heating elements.
• Try not to bend the film more than 90 degrees.

From the above we can conclude that installing an infrared heated floor system on our own is quite real. You can clearly view the entire process of the work carried out in the attached video.

Tile is one of the best options design of flooring in a bathroom, toilet or kitchen. It does not deteriorate from moisture and is very durable. However, when walking on it, your feet may feel uncomfortable because of the feeling of cold, because this material cools down quite quickly and does not retain heat. That is why infrared heated floors under tiles are an excellent option to make both the bathroom and kitchen as comfortable as possible.

On the construction market, there are several options for organizing heated floors in rooms - these are water and electric type, moreover, the latter come in two types - cable and film. Each of them has its own advantages and disadvantages, which can significantly affect the final choice of the home owner. And all the nuances should definitely be taken into account at the stage of designing and renovating the premises.

Water floors are a system of pipes through which flows hot water, supplied from the system central heating or from autonomous boilers. Such floors are usually installed using a screed, but there are options that can be installed without pouring cement mixtures.

On a note! Due to the need to fill the screed, the height of the ceilings in the room is reduced by at least 7-10 cm. Also, water floors cannot always be installed in apartments located in old buildings due to the impossibility of connecting to the centralized heating system (the load on it will be too great ).

An electric cable floor is a system created from a heating cable laid on a rough base and also covered with a screed. Sometimes the cable can be laid without filling cement mixture. This floor, as you might guess, works from the mains.

- it is too electrical systems, only the base is heated by infrared radiation. The system consists of thin film mats laid on the floor and generating heat. Typically, such floors are laid on top of a poured screed. One of the main advantages of using IR floors is the absence of a significant increase in the floor level due to the absence of the need to pour a screed.

Is it possible to lay film flooring under tiles?

It is easy to answer this question, but before doing so, it is important to analyze the operating conditions of the floor and look at recommendations for laying the system. The instructions for the heating sheets indicate that they can be laid under laminate, wood, and even tiles. Thus, installation of this system under tiles can be done with confidence.

On a note! IR floor systems can be installed even outdoors under porcelain stoneware slabs, since such heating is not affected by water. Thus, there will never be ice-covered paths near the house.

In general, IR floors are usually laid under laminate, carpet, etc. using the so-called “dry installation” technology. But, nevertheless, they are also laid under tiles, but using tile adhesive, and sometimes screeds or mixtures for self-leveling floors. However, in the last two cases, it is important to remember some features of the work.

In general, you can use cable flooring under the tiles - it will most likely last longer than film flooring, and is a type of floor heating specifically designed for this type of work. At least for a wet installation it is ideal. However, if you install infrared floors correctly and in compliance with all safety requirements (grounding, working in a dry room, etc.), there should be no problems with them.

Operating principle of film coatings

IR floors are a fairly thin film, between the layers of which there are strips made of graphite (carbon). It is these black stripes that are the very heating elements due to which the system begins to generate heat. There are also film floors completely covered with carbon. The film is laid out on the prepared floor base, connected via wires to the power supply and begins to heat up. All surfaces around the film are heated by infrared radiation.

Infrared film - photo

Due to the operation of the film, the floor heats up very quickly, and thanks to the “smart” thermostat, it turns off after heating. Thus, the IR floor only works for about 20 minutes per hour. If necessary, the system starts up again and heats the base.

Infrared flooring has the highest efficiency compared to other types of floor heating systems. It heats up quite quickly, while consuming a very small amount of electricity. Thus, it is very economical.

The film is perfect for installation in any type of room, be it a bedroom, a nursery, a living room or a bathroom with a kitchen. In this case, the laying of the sheets is carried out in accordance with the layout of the furniture in the room - where large-sized objects will be placed (sofa, cabinets, etc.), the film is not laid. The easiest way is to install it only where your feet touch the floor - for example, at the exit from the bathroom.

Attention! There are two types of IR floors - bimetallic and carbon. It is strictly forbidden to lay the first one under the tiles.

It is interesting that, unlike other heating systems, the IR floor heats the objects surrounding it, and not the air. Thanks to this, such a system has a positive effect on the formation of the microclimate in the room; it does not dry out the air, but, on the contrary, enriches it with negatively charged ions.

Characteristics of infrared heaters

IR floors can be easily adjusted by temperature - for example, by setting the thermostat to 21 degrees, you can achieve the most comfortable floor temperature. Although in general the system can be heated up to 50 degrees, this is not necessary. Since there are now quite a few manufacturers of IR systems on the market, you can easily select equipment at the right price. Installation can be done independently and quite quickly, and this will also have a positive impact on the wallet of the owner of the premises being equipped. And in some cases, IR floors can even replace centralized system heating.

Advantages of infrared floor

IR flooring has a considerable number of advantages.

1. The IR system does an excellent job of heating the surrounding interior items. The wavelength is 5-20 microns, which allows it to pass through the tile.
2. Adjust the temperature when installed system IR flooring is quite simple, which will create an optimal microclimate in any room.
3. Such floors are economical and consume little energy.
4. Human health will not suffer from significant electromagnetic radiation, as when laying cable flooring.
5. IR floors can become a kind of air ionizer.

IR warm floor under tiles - which one is better

Disadvantages of infrared systems when laying them under tiles

But IR floors also have their disadvantages. This is especially true for the option in which the system is laid under tiles.

Infrared heated floor under tiles: installation features

Installing infrared floors under tiles is not as complicated as it might seem at first glance. But there are several nuances that are important to take into account. First you need to worry about the materials and tools that you may need for the job. This can be a heat-reflecting substrate, the IR film itself in required quantity, tape for insulating wires, tiles and glue for it, tape, corrugated tube, drywall, contact clamps, polyethylene, connection wires, scissors, etc.

Infrared floor - installation

To lay both the tiles and the infrared heating system, you need a flat base. Therefore, it must be cleared of debris and inspected for damage and protrusions. There should not be any relief on it - all cracks are sealed, and it is recommended to sand off any bulges.

Also, preliminary work on the installation of an IR floor system includes the creation of a diagram for laying IR film and the placement of various elements such as a thermostat. In this case, the location of large-sized furniture and places where the film will not be installed should be taken into account. It is important to remember that all wires running from the heating system to the thermostat must be laid in a corrugation and groove cut into the wall. However, it is not always necessary to trench walls. Sometimes the wires are laid in a narrow plastic channel that is attached to the wall surface.

Attention! It is important to work with IR heating film carefully, as it is quite easy to damage. And they cut it only along clearly marked cutting lines. By cutting the film in another place, it can be rendered unusable.

All installation work should be carried out at air temperatures above 0 degrees, as well as at a humidity of no more than 60%. It is also important to ground the entire system. Particular attention is paid to contact insulation, as well as possible places film damage.

Table. Types of installation of IR film.

View	Description
	It is used when installing on the surface of IR film of laminate or carpet. It is used for installing tiles, but rarely. Involves careful leveling of the surface, laying thermal insulation material and directly the film itself, then - installation of a protective film layer (polyethylene), sheets of drywall and directly the tile itself, which is fixed with glue. In this case, the film is not exposed to contact with caustic substances and will last a long time. But the height of the base in this case turns out to be quite significant, which is not always relevant. In addition, this method of carrying out work will be more expensive.
	Used for laying tiles, stone, etc. The so-called classic method. The work will cost less than with a dry type of installation, but it is much more complex. In this case, the surface is also prepared, then a heat reflector is laid on which the IR film is mounted. Next, it is covered with polyethylene film, reinforced and filled with a mixture for self-leveling floors. Ceramic tiles are mounted classical method(on glue) on top of this layer after it dries. The heated floor system can be put into operation approximately a week after laying the tiles.

Installing infrared heated floors under tiles

Let's look at how the LamaHeat infrared floor is installed using the wet method. This is a special type of IR flooring that looks like chicken wire and is great for wet installation.

Step 1. The surface of the subfloor is thoroughly cleaned of debris. Then a lavsan heat-reflecting substrate is laid on it. Its individual strips are connected to each other using tape.

Step 3. This canvas is connected to the electrical network using special terminals and wires. The terminals with the wires inserted into them are clamped with pliers.

Step 4. The wire connection points are insulated using pieces of bitumen insulation on both sides.

Step 5. Using a utility knife, recesses are cut on the surface of the thermal insulation for laying wires in them.

Step 6 The ends of the IR sheet where no wires are connected must be insulated.

Step 7 A layer of self-leveling floors is poured on top of the IR mesh. The layer is carefully leveled and dried.

Step 8 The tiles are laid on the self-leveling floor layer. The tiles are attached to the surface using tile adhesive applied with a notched trowel.

It is possible to lay an infrared floor under tiles, but it is important to carry out all work carefully and carefully, being sure to follow all work rules. Otherwise, warm floors of this type simply will not please the owner of the apartment with their work - they will quickly fail. In general, such a system is quite reliable and has excellent quality of work.
