Heating mats involve the installation of thermal insulation material on concrete. At the moment, the most popular material for these purposes is polystyrene foam.

Heated floor mats with bosses

They almost completely eliminate heat loss and ensure that heat only goes upward. They must be resistant to mechanical stress so that the system does not fail. At the same time, it is important to take care of the waterproofing protection of the mats.

You can determine the functions of the waterproofing layer located under the mats:

1. Security for others adverse influence.
2. Reliability flooring.
3. Safety from leaks on floor slabs for neighbors living in apartments below.

When the installation has been carried out correctly, the mats additionally soundproof the room.

Expanded polystyrene mats and their varieties

Expanded polystyrene must also have certain characteristics for the heating system to work efficiently:

1. Firstly, the density of the material should be 40 kg per 1 m³. Only then will the system be resistant to heavy loads.
2. Secondly, the material practically does not conduct heat, therefore it ensures minimal heat loss.
3. Due to its cellular structure and other physical characteristics, polystyrene foam creates excellent sound insulation.
4. Protects from external influences laminated coating and centering locks located at the ends of the panels. Due to the good adhesive properties of the mats, the occurrence of gaps is almost impossible.
5. The installation pitch and mat sizes may vary.

Mats for heated water floors expanded polystyrene have their advantages:

• They are made according to European quality standards. Self-extinguishing raw materials are used during production.
• Wet and semi-dry screed can be laid on top of polystyrene foam.
• They do not deform, since the material is quite durable.
• They have clamps that make it possible to quickly install the pipeline.
• Installation of the heating pipeline is done according to markings applied to the surface. This promotes rapid distribution of heat energy in the room.
• Excellent physical characteristics.
• As mentioned above, they are characterized by sound insulation and thermal insulation.
• Do not harm the human body.
• They are not subject to rotting, do not allow moisture to pass through and do not swell.
• Fireproof and can withstand temperatures down to minus 180 °C and elevated temperatures up to 180 °C.

Mats, which are produced individually for laying pipes of a heated floor system on them, are a convenient solution. The slabs have bumps (bobs) on the surface. It is easy to pass pipe turns between them.

Expanded polystyrene boards can be as follows:

1. Extruded (XPS).
2. Pressless (PSB).
3. Press (PS).

They can also be smooth, embossed, foil or non-foil.

Let's take a closer look at each type.

Foil mats for heated floors

They can be made and contain mineral wool, polystyrene, basalt fiber, polyethylene foam, etc. On one side the mats cover. has different thickness (depending on the type of product). If these are slabs of foamed polyethylene, then the thickness will be from two to ten millimeters. If the slabs contain basalt fiber, then the thickness can range from twenty to one hundred millimeters.

During installation work, the mats are laid with foil facing up (for better heat reflection).

Foil plates with polyethylene foam are rarely used for installation on the first floors, where the house also has a basement. In this case, basalt fibers are often chosen.

Foil mats with basalt fiber

Film mats. Very durable polystyrene foam is used in production. The outside of the slab has foil on one side and is covered with a film of polymers.

A coordination mesh is applied to the surface of the film, which makes installation of the heating circuit easier. This allows you to save time on installation and do it yourself.

The good density of the material allows for sharp staples for fastening flexible pipes hold firmly.

The film over the foil is needed to protect the mirror reflective layer from the chemical rejection of the concrete, which comes into contact when pouring the screed on top of the thermal insulation.

Energoflex mats Energofloor Tacker

Profile mats. On the Internet you can even find such a name as mats for heated floors with bosses.

They are specially designed for installing underfloor heating pipes and are currently the most convenient. They are also made from polystyrene foam, only using the hydropellent stamping method. This makes the mats very dense and reliable for holding the shape of the pipes. Bosses are elements that are located on the upper plane.

Mounting mat Rehau Varionova

They can be in the form of a cylinder, parallelepiped or other shapes. The convexities are at such a distance from each other that the pipe is fixed very firmly and does not require additional elements fasteners The contour will not move when laying and pouring the screed.

A mat with bosses for heated floors is a structure made of high-strength polystyrene foam, so it can withstand dynamic and static loads. Such slabs are produced without coating, but still the best solution There will be a purchase of products that are covered with a strong polymer film.

Another advantage of profile mats is the ease of pipe laying. Installation can be done manually without outside help. To do this, you just need to carefully insert the pipes into the spaces between the bulges.

Expanded polystyrene mats Knauf Therm Warm floor

Mats for heated floors with clamps are inexpensive, but it is still worth considering a few recommendations so that you do not have to purchase low-quality products and be disappointed:

1. If you are faced with a choice of which design to purchase, definitely buy boards with a foil and laminated surface. You won't have to worry about waterproofing, and the heating system will work more efficiently.
2. Pay attention to the parameters: pipe diameter and laying step on the mat.
3. How thick the insulating part will be depends on the level of insulation of the floors. Consider the thickness of the screed and the final floor covering. If the floor does not need special insulation, then you can buy profile mats for heated floors with bosses minimum thickness and with a weak layer of thermal insulation, i.e. Only for light laying of pipe circuits.
4. There are many manufacturers. And in order not to make a mistake with your choice and purchase quality products, it is better to choose a trusted seller.

Laying mats

Laying heated floor mats, whatever it may be, must be done over waterproofing. The waterproofing can be a film coating of the surface of the subfloor or something else.

Bracket (harpoon) for attaching heated floors

They are fastened with locking joints. If there are any. Sometimes it may be necessary to fasten the structure to the floor if the mats are light and thin. This can be done with glue. Do not use metal fasteners as they may damage floor waterproofing and other properties of the mat.

If flat mats are installed that do not contain locking joints, then they can also be attached to the floor with glue.

There are many installation nuances, it all depends on the type of structure and its characteristics.

The pipes are laid after the warm mat has been completely laid.

Installation has its own characteristics. Before laying mats under a warm floor, several points should be completed. It is necessary to calculate the heating power (measured in Watts per 1 m²) and the area for the material. Then it’s worth deciding what the installation piping diagram will be. Schemes can be of the following types:

1. Spiral-shaped - suitable for rooms with a small area.
2. In the form of a double spiral - suitable for large rooms.
3. Serpentine - in this case, the pipes are mounted parallel to each other.

Review of manufacturers

When purchasing a mat for underfloor heating, it is important to pay attention to long-established manufacturers. Currently popular are Oventrop, Energoflex, Rehau.

Oventrop is a manufacturer from Germany that produces polystyrene foam mats. Its popular models are as follows:

• NP-35 is a version of the slab with bosses, which have excellent sound and thermal insulation properties. On one side the mats are covered with polystyrene film. They are used with conventional screed and self-leveling floors.
• WGL-045 is a version of the slab in the form of a roll; they are covered with polypropylene film. Used for pipes with a diameter of 1.4 and 1.6 cm and a laying pitch from 5 to 30 cm. Roll area 10 m².

Energoflex is a domestic manufacturer that produces quite a lot quality material. Its popular models are as follows:

1. Expanded polystyrene board. The bosses of the structure are 2 cm, they make it possible to lay pipes without additional accessories. The model has self-centering locks and applied markings. Mounted in 5 cm increments and designed for pipes with a diameter of 1.6 to 1.8 cm.
2. Energoflex TP. This is a version of polystyrene foam foil mats that have a coordinate grid on the surface (step is 50 mm).
3. Energoflex Super TP is a variant of mats for heated floors. Models are foil, with a coordination grid and a pitch of 5 cm.

Rehau is a manufacturer of polystyrene foam insulation boards from Germany. Mats with clamps for heated floors have a polystyrene foam soundproofing and thermal insulation layer three centimeters thick.

Mats for heated floors are thermal insulation design that allows you to make it in the house favorable microclimate, comfort and coziness. You should not save on insulation material and buy fakes that do not have a certificate. Most best option– purchase polystyrene foam boards, individually made for heated floors.

The efficiency of heating a home depends on the correct distribution of thermal energy. IN heating systems, called , the optimal distribution of thermal energy is provided by mats for water heated floors, used when laying flexible pipes with hot water coolant.

The figure below shows the laying of flexible pipes for underfloor heating of an autonomous heating system using heat-insulating mats.

History of application heated floors has its roots in ancient times. Streams of heated air rising from heated floors heated houses in Ancient Egypt, Greece and Rome, China and Korea thousands of years before our era. Ancient heating systems that heated marble floors from below were branched tunnel-type channels laid directly under the house. The heating agent in those days was hot air, heated by burning wood or coal in a fireplace near the house or in the basement.

The concept of ancient architects regarding home heating warm floors has been developed in our time. Heated floors are created not only in individual buildings, but also in apartment buildings with central heating. Residents of high-rise buildings are installing autonomous heating systems that allow the installation of flexible pipes with water coolant.

Modern system underfloor heating with water coolant is represented by a floor covering to which heat is transferred from the water coolant circulating through the flexible tubes of the heating circuit.

Autonomous underfloor heating includes the following operating elements:

• Flooring made from materials with high thermal inertia (wood, parquet, carpet, marble and stone). These materials slowly accumulate thermal energy from the heating circuit and gradually release it. In Fig. below shows how various materials underfloor heating coatings conduct heat and release it into the room. The thickness of the arrows symbolizes the power of heat flow from the material. Best performance– for ceramic and stone tiles, transfer heat worst of all wooden boards, covered with carpets.

• The heating circuit is made of flexible plastic of small diameter (16-20 mm), through which hot water coolant circulates.
• to reduce heat losses from the walls of the heating pipeline towards the bottom concrete base.
• Heat-conducting elements for transferring the thermal energy of the heating circuit upward to finishing coating floor of the room.
• Waterproofing of the heating circuit.

The figure below shows one of the options for arranging heating with water floor heating. The water circuit pipes are laid in layers of thermal insulation and fixed with cement-sand screed. The same screed transfers heat to the two-layer floor covering. The damper tape glues the waterproofing along the perimeter of the room wall.

Thermal insulation functions

The cylindrical surface of the flexible heating circuit tubes radiates heat evenly in all directions. In this case, part of the thermal radiation is directed downwards towards the base on which the hot tubes are laid. Thermal energy, aimlessly spent on heating the concrete base, is comparable in consumption to the energy usefully given for heating the room. Arrangement of thermal insulation in the area of ​​the heating circuit is important stage when creating an effective heating system with water floors.

The thermal insulating substrate, which is used when laying a flexible circuit with coolant, performs three main functions:

• thermal insulation hot surface heating circuit tubes from cold surface concrete base, preventing heat flows from flowing towards it (heat-saving function);
• redirection of heat flows coming from the heating circuit to the base in the opposite direction - upward, towards the floor covering (heat-reflecting function);
• rigid fixation of flexible tubes in accordance with the selected laying pattern (“snake”, “snail”, combined patterns) in order to optimize the operation of the heating system.

Insulation mats for thermal insulation

Laying thermal insulation of a water floor pipeline system is the most technologically advanced when using insulation mat. The simplest option such thermal insulation - flat mats for underfloor heating with water heating, which fully justify their name (from the German Matte - a mat made of matting, hemp or other rough material).

The tubes are laid on top of the mat and fixed on their surface to prevent the pipelines with the coolant from breaking. In Fig. Below is the laying and fixing workflow polymer pipes over smooth mat.

The installation process is greatly simplified if you use mats for heated floors with raised protrusions that facilitate quick and correct placement pipes according to the selected laying scheme.

Thermal insulation from mat must meet the following requirements:

• increased thermal insulation properties, ensuring minimal heat losses and economical operation;
• high strength qualities, allowing to withstand mechanical load from weight without deformation concrete screed, weight of the pipeline system with coolant and other loads;
• moisture resistance in case of possible condensation or leaks of the flexible pipeline;
• chemical and biological stability, preventing rotting or decomposition during operation;
• soundproofing properties;
• light weight when mounted;
• fire safety.

The following requirements apply to heat-insulating mat materials for a heating water circuit:

• low thermal conductivity;
• high level of reflectivity of thermal radiation (infrared range);
• resistance to static and dynamic influences during operation;
• material density of at least 25 kg/cubic. m;
• stability of parameters under temperature changes;
• environmental cleanliness;
• biological resistance to the effects of fungi and harmful bacteria;
• resistance to chemical aggression of concrete that corrodes the reflective foil layer after pouring the fixing screed for the floor covering;
• ease of use during installation activities.

Many helpers thermal insulation materials fully comply with these requirements, however, the installation of thermal insulation from industrially manufactured mats allows you to achieve optimal heating results for the floor covering.

Materials for heat-insulating mats

The most popular materials for mats for water-based floors in private housing construction are modifications of polystyrene and expanded polystyrene. On initial stage For the introduction of mats into heated floor systems, foil-clad polystyrene foam products were used. These were standard smooth slabs 3 cm thick made of polystyrene foam with a density of 30 kg/cube. m.

A coordinate grid was applied to the surface of the slabs, simplifying the procedure for marking and laying the heating circuit tubes. work surface The slabs with markings were covered with foil to reflect thermal radiation.

The following disadvantages were noted for polystyrene foam foil boards:

• the need to protect the reflective mirror of the foil surface of the plate from chemical aggression of the components concrete mortar, poured during screed formation;
• the need to use fasteners to fix coolant tubes on the stove;
• high probability of displacement and damage to the water pipeline when pouring the solution.

Often, when preparing thermal insulation for water-based floors, products made from polystyrene foam and polystyrene foam are confused. By chemical composition These are related materials, expanded polystyrene is a type of polystyrene foam.

The difference lies in the manufacturing technology, which predetermined the different physical and mechanical parameters of these materials:

• the density of ordinary foam plastic does not exceed 10 kg/cub.m, while the density of polystyrene foam is from 30 to 40 kg/cub.m;
• polystyrene foam has a granular structure, polystyrene foam has a homogeneous structure;
• expanded polystyrene has higher mechanical strength;
• polystyrene foam has high vapor and moisture absorption, which provokes rapid destruction of foam structures in a humid environment with temperature changes.

Polystyrene with a density of up to 40 kg/cub.m is used for the manufacture of profile mats with molded bosses, allowing the installation of a pipeline system without fixing devices. The polymer film protects the mirror layer of the foil coating from the effects of concrete mortar. Polystyrene mats are equipped with side locks, with the help of which the plates are connected to each other to form a continuous heat-insulating coating.

Mats for water floors

There are several types of mats for water floors, let's take a closer look at them.

Foil mats

Foil matte boards include mats made from mineral wool, basalt fiber, expanded polystyrene, foamed polyethylene (penofol) and other materials. One side of the plate is covered with foil.

The thickness of the heat-insulating substrate depends on the type of product:

• laying mats made of penofol have a thickness of 2-10 mm;
• mats based on basalt fiber are produced with a thickness of 20 to 100 mm.

During installation, the slabs are laid with the foil side up so that its mirror surface reflects the incoming heat from the coolant to the floor.

To fix flexible water pipes you need special devices: staples, clamps, metal mesh.

Products with a foil surface based on penofol are of little use for installing heated floors on the first floors of houses with basements. In these cases, mats based on basalt fibers are used.

Thermal insulating boards with film

High-density polystyrene foam (up to 35 kg/cubic m) is used in production. Foil is applied to the surface of the mat on one side and covered with a polymer film. A coordination mesh is factory applied to the surface of the film, making it easier to install the heating circuit.

The film is laid on top of the foil in order to protect the mirror-reflective layer from the chemical aggression of the concrete solution that comes into contact when pouring the screed over the thermal insulation.

The density of the material allows it to be securely held by sharp staples for securing flexible pipes.

Profile mats

Profile thermal insulation consists of polystyrene mats equipped with shaped protrusions (bobs) arranged in even rows along the outer surface. The thickness of heat-insulating mats with bosses reaches 35 mm. The bosses are given a cylindrical or cubic configuration, the height of the bosses is 20-25 mm. The purpose of the bosses is to ensure tight laying of the heating circuit tubes before pouring the screed.

The cost of products whose surface is filled with bosses is higher than the prices for models with smooth surface. However, they are popular due to their convenient installation, high-quality sound insulation and ease of cutting when assembling a monolithic heat-insulating board.

Manufacturers of thermal insulation mats

Manufacturers of thermal insulation products on the market building materials plenty.

At the same time, the most popular mats are from only three leading brands:

• "REHAU" (Germany) - produces polystyrene mats with sound, - and thermal insulation layers. The mats are supplied with clamps for securing the heating circuit tubes.
• “OVENTROP” (Germany) – produces smooth and profile mats. The company's products have high sound-proofing and heat-protective properties.
• Energoflex (Russia) – produces rolled foil polyethylene and polystyrene. The production of polystyrene foam boards with two-centimeter bosses was launched.

Video

Using the example of heat-insulating mats, it is obvious how the development of production technologies is changing the methods of heating a home that have evolved over decades. From simple mineral wool underlays to profile slabs that ensure precision installation and minimal heat loss - this is the result of constant innovation from leading heating equipment manufacturers.

The efficiency of floor heating depends solely on properly organized thermal insulation of the base; mats for warm water floors are ideal for this. Without this ingredient, the whole idea becomes meaningless. For this purpose, sheet or roll polymer foams – mats – are used. In this article we will look at what mats there are, how to choose and use them correctly.

Their main task is to minimize heat loss. All other functions are ranked far in second place.

Types of mats and their characteristics

Mats for water heated floors are in almost all cases made from extruded polystyrene foam. This material has a lot positive qualities:

• Low thermal conductivity.
• Service life of at least 40 years.
• There is virtually no water absorption.
• Excellent sound insulation.

Application of mats for warm water floors

But at the same time, there are a couple negative properties:

• Flammability.
• Instability to solvents.

We learned to cope with flammability. To recognize polystyrene foam as fireproof, during its production, carbon dioxide is used instead of air for foaming. But poor resistance to solvents cannot be corrected. Therefore, manufacturers place each such mat in a film of polyethylene terephthalate (PTEF) or even polyethylene. At the same time, under the film there is also a layer of foil, if there was one on the mats.

Also on sale heating mats for electric heated floors. But this is a little different, because... The heating element in this case is a resistive cable.

To facilitate the work of laying water-heated floor mats, some manufacturers produce sheets with locking fixation. The fastening of such slabs resembles the connection of a laminate.

Somehow dividing such mats into groups is quite problematic. Because they have the same material, only the release forms differ. And so, mats for warm water floors are:

• Leafy
• Rolled

Sheet mats, these are polystyrene foam boards, which have two-centimeter protrusions - pegs - formed on one side. Mats with pegs are called “mounting mats”. This size of bosses allows you to fix pipes with a diameter of up to 20 mm between them. They do not have a single sheet size. Therefore, each manufacturer has its own standard sizes and methods of attaching one sheet to another. There are “composite mounting mats” on sale, for example the NP series from Oventrop. For those top layer with protrusions, has a base thickness of only a few millimeters. And it needs to be laid on already laid polystyrene foam slabs. On the one hand, this is convenient, because you can choose the thickness of the insulation to suit your needs. But the price for such products is off the charts.

Square meter of mounting mat Oventrop costs $25, and that's without the insulating layer. Domestic manufacturers sell their products cheaper. From the manufacturing company Format, a one-piece mounting mat with an area of ​​1 m2, made of polystyrene foam 4 cm thick, costs only 400 rubles. At the same time, the Russian company integrates bottom part mat bubble film, which, in addition to improving the quality of heat and sound insulation, contributes to a more even fit to subfloor. And add here the locking joints on each sheet.

Roll mats They are the same, only narrower, sheets, but glued to a polymer matrix. As a result, they can be rolled. By appearance, they resemble a tank caterpillar. To fix the strips to each other, they have a self-adhesive tape along one edge, and an overlap film is left on the other. Such mats for heated floors no longer have protrusions for fixing pipes, but they have markings on them, in increments of 5 cm. Accordingly, you can fix the pipe in them using:

• Mounting tape.
• Staple harpoons.
• Clip.
• Reinforcement mesh.

The prices for rolled mats are also unreasonably high. For example, roll from ROTH, will cost 385 rubles/m2, this is with a material thickness of 3 cm. But it will require clamps for the pipe. Domestic manufacturer " ROLS ISOMARKET", which produces products under the Energoflex brand, offers a roll mat of the Energofloor®Tacker series, 353 r/m 2, with a thickness of 3 cm. It also has installation mats of the Energofloor ® Pipelock series, which instead of rounded pegs; oddly shaped fasteners are located on the front surface. Sheets measuring meter by meter and 30 mm thick cost 965(!) rubles.

Pros and cons of using mats when laying

The advantages of such mats include the extreme simplification of thermal insulation and pipe laying work. This is especially true for mounting mats. Simply press the pipe between the protrusions and it is already fixed.

Rolled mats are also convenient in their own way. But not by the release form, but by the fact that markings are applied to them. With its help, it is convenient not only to place pipes according to plan, but also to combine thermal insulation elements during installation.

Please note that all the advantages are not in the area of ​​increasing the efficiency of water heated floors, but exclusively in the area of ​​installation. After the work is completed, no one except you will know what is under the screed.

But the disadvantages of these materials are quite significant. And above all the price! To deal with this issue, you need to give all the prices from common denominator. Let's say the price is for 1 m 3. At the Format company, square sheet 4 cm thick, costs 400 rubles. This means that there will be 25 sheets in 1 m3. And it turns out that the price for 1 cubic meter = 400 x 25 = 10,000 rubles. Another Russian manufacturer, « ROLS ISOMARKET", a sheet of mounting mat meter by meter, 3 cm thick, is offered for 965 rubles. This means that 1 m3 will cost 33.3 x 965 = 32134 r/m3. With a declared density of 35 kg/m 3, one kilogram of this expanded polystyrene costs 920 rubles (!) And yet polystyrene itself costs about 50 rubles/kg.

By the way, an ordinary sheet of extruded polystyrene foam with a thickness of 5 cm and a density of 37 kg/m 3 costs 210 rubles/m 2, or approximately 114 rubles/kg.

How to lay pipes in mounting mats with bosses

With this foundation, the process of laying pipes turns into a holiday. Following a pre-prepared plan, you need to bring the pipe into the room, and moving along a certain route, press it between the bosses. All!

Just? Yes, but you will have to pay dearly for it (prices are written above). Even for a beginner, laying 100 m of pipe on mounting mats takes no more than half an hour. Then you can begin pressure testing the system.

Laying pipes on roll mats

Depending on the mats used, the options for attaching the pipe may also change. The cheapest way is reinforcement mesh. It is laid on top of the thermal insulation and the pipe is fixed to it using clamps (or wire). The disadvantages of this method are:

• Increasing the volume of work.
• Adding an additional item to the work - laying the mesh.
• The need to carefully monitor pipe bends (possible bending).

bupropion hcl.jpg 800w" sizes="(max-width: 533px) 100vw, 533px" />

But the advantages are also significant. This is the most reliable way. After all, the reinforcing mesh is connected into a single fabric, and this ensures its stability and solidity. And after pouring the screed, nothing but joy from the work done will be noticeable.

Fastening with mounting tape (tire) has its own characteristics. Such a tire is fixed to the surface of the thermal insulation every 25-30 cm with special clips (or anchor harpoons). The distance between adjacent tapes is no more than 25 cm. Fixing the pipe is possible in different ways:

1. The pipe is secured in the mounting tape using folding tabs.
2. The pipe snaps into the mounting strip in much the same way as between the pegs of a mounting mat.
3. The pipe also snaps into place in the mounting rail, but there is a fundamentally different type of lock.

Some manufacturers of accessories for installing water heated floors offer special metal rotary plates. But they are more required when installing water heated floors without screed.

It is advisable to use pipe fastening with clips and harpoons if all components are purchased from one manufacturer: pipes, rolled mats, tires, clips (or harpoons). With such an integrated approach, it is highly undesirable to deviate from the technological process.

The entire set of accessories is offered by the manufacturer " Rehau" But it is recommended to attach it with harpoons only to branded roll mats. Just in case, we add that the harpoons must fix the pipe every 25 cm.

A pipe with a diameter of 20 mm is laid in increments of 0.2 m. This is a standard value, but it is not an axiom! Depending on the location of rooms, windows, external walls, the frequency of installation may vary. For example, in a children's room, we recommend leaving 15 cm between pipes. The same distance is recommended in the hallway and bathroom. Near walls with windows or a balcony door, you can make the step denser, 12-13 cm.

At the same time, after passing through a critical area of ​​the room, you can take fewer steps. Carefully monitor the bending radius of the pipes! Don't reduce it!

Particular attention should be paid to the thickness of the screed. The fact is that if the screed is not massive enough (3-4 cm), then you can constantly feel the “zebra effect” with your feet. That's why The minimum thickness of the screed should be 5 cm.

At the end we will add about the direction of laying the water heated floor pipes. Try to organize the installation of the system in such a way that the hot coolant first passes through pipes laid along the coldest walls.

The use of special mounting mats when organizing a water heated floor is extremely attractive, but extremely expensive. In some cases, the cost of such thermal insulation can be half the budget.

Heating and floor heating systems have gained a strong foothold and have gained confidence among the population. Most people prefer to heat their homes this way. It is important to correctly install the system and ensure proper thermal insulation. The main function of a heat-insulating floor is to direct warm air masses from the floor heating system upward to heat the floor surface and room.

In addition to the pipes through which hot water moves, a special layer of material is needed to distribute heat.

The correct choice of such material will save on electricity. Products made of polystyrene foam installed on a structure made of water floor tubes are recognized as the best in terms of functionality.

These additional devices for the heating system must be resistant to weight loads and not deform during operation. Failure to comply with this rule will disrupt the proper functioning of the heating system itself.

Mats completely eliminate heat loss. The operation of the device is simple. Heat accumulates in this layer and rises. The cooling air descends, warms up, and air currents rise to the ceiling. This cycle happens constantly.

There is a lot written in articles on the Internet about installing a heated floor circuit. And the question of how to preserve heat using them is not considered.

Parameters of mats for heated floors

An inexperienced beginner installs a floor without a thermal insulation layer, and then wonders why so much electrical energy is wasted.

The cost of this material is inexpensive, but it significantly increases the efficiency of the warm water heating structure and its durability. Ignorance of this detail will not allow you to save money if your floor heats floor slabs or concrete screed.

Mats contain many functions. The most important are protection, distribution and direction of warm air. How does this work?

Thermal circuits are laid on a concrete base and, as a rule, filled with concrete screed on top. Naturally, during operation the pipeline will experience loads.

It is necessary to secure them at the installation stage before laying. To do this, a special protective substrate is placed under the tubes - construction mats.

It will protect the water-heated floor structure from contact with concrete. The material from which they are made must be dense and withstand heavy loads. In addition, they prevent the bevel of the laid coolants during the pouring of the screed.

It is necessary to lay a waterproofing layer on the substrate to protect the neighbors below from sudden pipeline leaks. It is installed at the top and bottom to protect it from the effects of the concrete environment.

During the operation of the underfloor heating system, the insulating layer heats up evenly and transfers heat to the concrete poured on top, distributing it over the entire surface.

The main feature is that, by generating heat, they warm up the upper base. Therefore, warm air masses quickly warm up the room.

In an apartment building, sound insulation is very important. This is another task that construction substrates cope with remarkably well.

Materials from which mats are made

Previously, the pipes in the system were laid with ecowool or ordinary foam. Today's technologies have come a long way.

Expanded polystyrene is the main raw material for the manufacture of the insulating layer. It has many advantages compared to other materials.

The advantage of thermal insulation material

The production of mats using high technologies from modern materials meets European recognized standards of safety and quality.

They have the advantages of conventional insulation materials, but they do not have their negative qualities. Advantages:

The polystyrene foam material itself is very flammable and, when burned, emits dangerous acrid smoke, so in production it is treated with special fire retardants. This allows it to self-extinguish.

Types of expanded polystyrene boards

The choice of a heat-insulating layer largely depends on the base of the floor, on the weight load, which can be quite large, and on the type of room itself. Sheets have different thicknesses, take this criterion into account when choosing.

In production, penofol is used, the thickness of which is 2-10 mm. The outer side is covered with foil, and the bottom has a plastic film.

This allows the insulating material to store heat upward and distribute heat flow throughout the room. Suitable for additional heating as it has low thermal insulation properties and is conditionally classified as construction mats. Due to low performance.

When laying coolants on such an area, it is necessary to additionally lay a reinforced mesh to secure them with clamps or brackets. In addition, they do not have a lock and the joints need to be taped.

But its use is advisable in low rooms, where every millimeter is valuable.

Expanded polystyrene boards

This is a more durable, reliable and high-quality insulation, in contrast to the cheap analogue of polystyrene foam. Penoplex is the leader in this series. It has standard length and width dimensions of 60x120 cm.

The thickness of the mat varies from 2 to 10 cm. It has a cellular structure, which has high density values ​​and can withstand heavy weights. To increase thermal insulation, the material can be rolled out on top of the laid tile mats.

The sheets are equipped with locks on the sides, which allow you to quickly assemble the coating. Some manufacturers equip them with markings for tubes, which are attached to the plane of the insulating layer with plastic clips.

They are tiles covered with foil on one side and with plastic film on the other. They are made in the form of independent tiles with a lock joint, or they are combined into rolls with a single layer of film coating.

In one case, they will need to be glued with moisture-proof tape during assembly, and in the latter, simply laid out on the floor. In essence, this is a ready-made structure that just needs to be rolled out on the floor and glued. There is no need to make an additional layer of foam foam.

Some models already have adhesive self-adhesive strips. A mesh is applied on the outside for easy placement of the pipeline on them. The grid pitch is 5 or 10 centimeters. The pipes are fastened with staples to the sheets. You can pre-lay the armored mesh.

Construction products with protrusions “bosses”.

The most convenient and easy-to-install insulation of all types presented on store shelves. Their design is designed specifically for underfloor heating systems.

Modern manufacturing technology using special stamping creates small protrusions on the surface coating, which are called “bobs.” They allow you to attach tubes in them, and the structure will not move when you pour concrete.

These protrusions can be of various configurations: round, square, cylindrical, and polyhedron. They are located at the same interval and ensure strong fixation of the tubes on the substrate area.

Their height is from 20 to 25 mm. This is quite enough for installing pipes with a diameter of up to 2 cm. The thickness of the insulating product is 4-5 cm.

Top coating varies by manufacturer and model. There are slabs that are produced without any coating at all, then you will have to buy it separately.

The sheets have locks for easy installation. These connections create a tight seal between the sheets. The cushioning layer forms a smooth surface without gaps or cracks.

Expanded polystyrene boards create a noise barrier and can reduce sound waves by up to 25 dB. Which is also not unimportant.

Aspects of choice

The cost of construction lining materials is relatively low. However, in order to buy high-quality mats for heated floors, you need to know the following rules.

When purchasing, ask the seller to show the certificate of conformity of the selected product with environmental and fire safety.

Cheap, non-certified products do not withstand the loads placed on building insulation materials well, and the purchase may disappoint you as a waste of money.

Manufacturers

There are many manufacturing companies represented on the modern Russian market. The main and proven three leading brands are:

1. NP-35 – profile mats with projections with good characteristics with a film surface on one side. Can be used with self-leveling floors.
2. WLG-045 – roll models with polypropylene film.

1. “Energoflex TP” are polystyrene foam sheets with an applied foil layer and markings for tubes, 50 mm in pitch.
2. “Expanded polystyrene board” - mats with twenty-millimeter “bobs” on which it is convenient to place tubes without fasteners. They have a locking connection around the perimeter and markings for pipes.
3. "Energoflex Super TP" is a rolled insulating material with foil and coordination markings.

Regardless of what mats will be used when installing a heated floor, experts advise installing additional waterproofing.

This must be done to protect the lower layer of the foundation from water and prevent flooding of the lower floors. Bitumen or a special waterproof film can serve as waterproofing.

It must be glued with special tape. The same adhesive tape must be used to seal the entire perimeter of the room after installing the backing.

Installation of profile lined insulating materials is the simplest. They are laid out and connected with special locks located along the perimeter of the sheet. Then the tubes of the heated floor system are laid into the protrusions and fixed in them.

Installation of smooth ones involves either a key connection or gluing the tiles to the waterproofing. Be sure to seal the joints with waterproof tape.

Rolled insulation is laid with the foil side up. It is glued to the base, and the gaps between the rolls are sealed with moisture-resistant tape.

Then, with a pencil or marker, the places for laying the structure from the tubes of the future thermal circuit are manually marked on it. The tubes are fixed with clamps or special clips.

It is important to note that the pipeline is fixed to the surface of the material only with plastic fasteners, otherwise the metal will damage not only the waterproofing, but also disrupt the technological characteristics of the mat.

Lay the system only after fixing the lining material to the floor plane. The pipes are laid out at the same distance from each other, which ensures uniform heating of the entire floor surface.

In conclusion, I want to say that this is not the material that you should save on when installing a heated water floor system.

The examples given show how technologies in their production have expanded: from basic flooring made of mineral wool, to specialized slabs, with a marked plane for the precise installation of a pipe system.

The correct choice depends on the room in which the heated floor is installed, on the careful calculation of the area, the purchased material, and on the quality of the material. And the improved material makes installation easy even for a non-professional.
