- With bulk protrusions. Pretty creative way, allowing for any paving configuration, as desired by the owners. Some people think that the fixation of the pipes provides a small distance between the protrusions, but this opinion is erroneous. For this purpose, special fasteners for underfloor heating pipes (clips) are used, which ensure reliable and durable fastening of the circuit. There are special bosses to protect the tubes from mechanical influences. All components are quite expensive.
- With fixing protrusions. The main difference between this method of attachment from the previous one is that the pimples on the surface of the board can provide a secure fixation of the pipes, without the need for additional fasteners for underfloor heating. Installation is carried out simply by pressing the pipe between the adjacent ledges. To attach the underfloor heating pipes to the Styrofoam is characterized by a high degree of convenience and reliability. These boards are not damaged even when accidentally shifted on the floor, being an excellent combination of functionality, quality and price.
It should be said that such systems are often found in the market and specialized stores. Before fixing the floor heating pipe to the polystyrene foam, it is necessary to make a detailed drawing of the laying: this will allow you to buy the right amount of material in advance.
How to attach a warm floor to the penoplex?
Today, the presence of floor heating in the house or apartment is not a luxury and is not uncommon. Any private homeowner or apartment can easily buy it and install it, either independently or with the help of specialists (depending on the type and method of mounting pipes warm floor). Most often such floors are installed by people not for their comfort, but for children. In addition, the heat from the floor is evenly distributed over the entire area of the room in which it is installed. Now in the markets and in specialized stores customers are a wide range of a variety of underfloor heating. Their differences only in price and method of installation.
2 types of water underfloor heating
The most common type of water heated floor is considered a concrete installation system. That is, the pipes are filled with concrete and no additional structures are required.
The least common type of water heated floor is considered a polystyrene installation system. In this system of installation such structures are used as: plates with grooves, plates made of aluminum and the pipe itself.
Methods of fixing pipes for underfloor heating are as follows:
Fixing the pipe to the reinforcing grid
The pipe is loosely attached to the mesh (a few centimeters distance), fixed with special clamps. one clamp at a distance of one and a half meters from each other, but if the pipe bends 90 degrees, the pipe is fixed with three clamps for a more secure fixation.
On our second channel, Andrey Elfimov told about a useful tiphack on fixing the floor heating pipe to the reinforcing mesh:
Advantages: All elements of this method of fixing pipes are available in specialized stores or at the market. Simple and reliable method.
Disadvantages: Time-consuming installation process. The possibility of damage to the pipe is not excluded, since often metal plastic pipes are used.
Fixing the pipe on the mounting rails
This method is not more complicated than the previous one. Pipes are fixed with special clamps that hold tightly and protect the system from mechanical damage. Also, such systems are easy to install on the wall, the only problem is that it is quite difficult to find in specialized stores such a heating system. In addition, the difficulty arises in the preliminary marking. But in general, this method is very convenient and practical.
A very creative way of installing pipes. Because with the help of volumetric protrusions in the coating pipes can be laid in any pattern you want. Despite the small distance between the projections, many think that it will fix the pipe, but this is far from it. For fixing, you also use special clips that ensure the reliability of a lasting fixation of the pipe.
Advantages: The tube is protected by special barrels from mechanical damage. Such a system can be freely purchased at the market and in specialized stores.
Disadvantages: Rather high price for all components. To fix the pipe it is necessary to use additional elements.
This method of installation is very similar to the previous one, but there are significant differences. There are special ledges on the flooring which hold the pipe firmly in place without any additional equipment. You can fix the pipe in a very simple way: gently pressing the pipe between these protrusions.
Advantages: This method of fixing the pipe is considered very convenient and reliable. The board is not damaged by moving around on the floor. Excellent combination of functionality, quality and price.
Disadvantages: The cost is much higher than the above examples. Such a piece is quite difficult to find in the markets and specialized stores.
Fixing with a tacker
The fastening of the tube is carried out with a special device. a tucker, which holds about 120 clips. The pipe is fixed on the marking with this device. The process takes a small amount of time, but despite the speed of fixing the pipe, fastening is very reliable. The only disadvantage of this method is the cost of equipment. 230 euros. It is very difficult to find it in the domestic specialty stores. This method of attachment is suitable for installers and qualified specialists in the field.
Which way do we use?
For a long time we used the method of fixing the pipe on the reinforcement mesh. There were many reasons for this: the price, the lack of other offers and the expensive delivery to order. Now we bring in the anchor brackets and secure the pipes with a tucker. It noticeably speeds up the installation process. Difficulties usually arise when pipe lines are at a close distance. Tucker does not fit in the gap between the pipes, and our tucker often makes false positives. It is not yet known whether this is a feature of all tuckers or just ours.
The overlaying method of laying floor heating
Styrofoam for underfloor heating on wooden joists Concrete screed promotes even floor heating. However, if its laying is not possible, water circuit pipes can be mounted in heat distribution plates.
At the initial stage of the works on installation of the heating contour using the concrete-free method, the substrate is also prepared: it must be even and clean. On the subfloor a layer of waterproofing and foam plastic boards are laid, fastened together with construction adhesive tape.
The main difference between the flooring method and the concrete method is the impossibility of using smooth foam boards. It is very important that they are provided with grooves, in which the heat distribution plates will be inserted. Pipes of the water circuit are laid in grooves, which are equipped with heat reflectors.
Electric variant of heating can be laid on the foam plastic without screed only if not a cable system is used, but special mats.
Installing a light, underfloor heating system
Then, as in the previous case, check the performance of the systems and proceed to lay the final coating. The laminate flooring can be laid directly on the heat reflectors by first laying a carpet pad on them. And tiles and other flooring approved by the manufacturer for use with underfloor heating systems require a flat surface. Therefore, lay a sheet of plywood, OSB or moisture-resistant gypsum board on the heat distribution plates.
Heat distribution plates in the floating floors
In wooden houses, the installation of water loops is most often made in special wooden modules installed on foam plastic boards. Heat distribution boards are also installed in the modules, in which a water pipe or an electric cable is placed. When using the overlay method of laying contours, the thickness of the floor increases slightly.
Features and properties
At low weight, foam plastic withstands high loads, while not weighing down the construction. Without insulation the heat loss through the floor is more than 10%, and after laying the material heat loss is reduced to a minimum. Laying polystyrene under the concrete screed is one of the reliable ways to insulate the floor.
- Foamplex is a very durable material, you can walk in it with no fear of damage.
- Working with the material does not cause allergic reactions, as, for example, with mineral wool. Foam can be laid without gloves, it is environmentally friendly and does not damage the skin.
- Polystyrene does not form gases and volatile substances.
- The material does not absorb moisture, the insulating properties are guaranteed for 30 years.
- Heat loss in the room is reduced by 20-30%.
- The treated ends allow the boards to be laid flat against each other.
How to install Hep2O ed polystyrene system for underfloor heating
Installation of foam plastic is available even to those who have no experience in construction and repair. With the help of locks at the joints, the material is quickly connected, not creating difficulties in the work.

proposes to use the “Rautherm Speed” system as a fixture for the underfloor water line. It consists of a covering, on which the fine loops are placed, and a ribbon, on which the hooks are placed. The system works on the principle of Velcro. Buy the mounting system from dealers, in St. Petersburg.
A tape is wound around the pipe and placed on the mats with loops. Hooks enter the loops and fix the contour in a certain place. If necessary the position of the line can be adjusted.
The mats have a thickness of 3 mm. They are additional thermal insulation material for the floor, prevent the penetration of noise into the room.
On the outside, they have a sticky surface which is secured with tape. When laying mats detach the tape, and roll on the surface of the floor. The material is designed for pipes with a diameter of 14-20 mm. Withstands pressure of 6 bar and temperature of 95 0C. The installed system is filled with a concrete screed.
For fastening the pipeline floor water mains use a variety of devices. Choose methods according to the efficiency of installation, the cost of the product. Small costs are required for laying the pipeline with reinforced mesh and mounting tape.

The differences between foam and foamlex
For home owners who want to change their home, the quality and cost of the material can be a deciding factor. Inexpensive foam plastic differs from high-quality insulation called Foamplex. What to choose, where price and quality compete.
There are opinions that the foam board is just a beautifully decorated plastic foam, but the practical difference does not exist. However, practical use confirms the positive results.
The new insulator slowly absorbs water (5 times slower), so the foam absorbs moisture faster. For example, the foamlex is submerged in water for 24 hours, the moisture absorption rate is close to zero.
In terms of thermal conductivity, comparing these building materials, foam plastic is significantly inferior to modern foam plastic by 33%.
The foamlex shows high qualities in terms of sound insulation. Therefore, the use of such material in floor units and in wall bulkheads is preferable. The numerical values of the difference reach up to 41 dB.

According to the degree of compression, the record is established in favor of foamlex, where the parameter is three times higher than that of foam plastic.
The service life of the advanced insulation reaches 50 years. This means that it will last 5 times longer than cheap foam plastic.
If you check the merits by the amount of insulation used, with foamlex the result is half as much.
The figures eloquently emphasize the merits of modern engineering advances in the field of improvement, renewal of construction resources.
Therefore, when planning serious measures to improve your home, you should opt for extruded polystyrene foam with the best and most effective performance.

Distinctive features of the foam plastic
The Penoplex is a thermal insulating material used in construction. It is obtained by foaming polystyrene, extruding the resulting material through a molding hole. As a result of these manipulations, the structure of polystyrene is complemented by micropores filled with air. This technology allows from an ordinary foam plastic to obtain a durable material with high thermal insulating indicators.
The thickness of the board varies from 2 cm to 10 cm. Plates can have the following dimensions:
Physical properties of foamlex
From other materials, laid under the warm floor, foam polystyrene differs in a number of advantages.
- Thanks to the special structure of this material does not absorb moisture at all.
- Foamplex has the lowest thermal conductivity coefficient.
Advantages of foamlex
The laying of a warm floor on the insulation allows to heat namely a room, instead of overlaying the floor or basement room. Due to the low thermal conductivity of foamlex, the heat flux is not dispersed downwards, but is directed strictly upwards.
Independent installation of insulation
Masters before the work stock up on the necessary improvised material:
- A new type of insulation is foam plastic;
- means for gluing;
- With a measuring device (level);
- Installation reinforced mesh;
- priming material;
- polyethylene film.
The installation of foam plastic begins with a good cleaning of the working area from debris and unnecessary things. Then the insulating material is spread around the perimeter of the floor. Gaps, gaps should not be allowed.
The tiles need to be mated and taped together. Then, according to the standard scheme, installation is carried out with filling of the screed.
