Enclosures must be heat insulated to ensure that the indoor climate is as comfortable as possible.
To prevent unnecessary heat loss, mold, fungi and condensation, expanded polystyrene for the warm floor has been widely used.
Professional builders refer it to one of the most optimal, reliable and modern materials.

Choosing foam polystyrene
In most cases, expanded polystyrene for a water-heated floor is a plate of different colors( often blue), which at first glance resemble foam rubber.
This material is one of the varieties of foam, which is obtained by combining the atoms of two elements: hydrogen and carbon.
It is produced by foaming an extruded granular material using volatile oil products. To obtain the desired effect, dry water vapor is used.
The greatest popularity among potential buyers was won by extruded polystyrene foam for the warm floor.
It is one of the best heaters, having a low coefficient of thermal conductivity.

Another characteristic that can be attributed to the weighty advantage of the material - low capillarity and low absorption of water and its vapors.
Thermal conductivity of expanded polystyrene does not change even under constant exposure to moisture.
Extruded polystyrene foam has one of the lowest vapor permeability among heat insulation materials.
In a layer 2 cm thick, it is commensurable with that of a roofing material.
Recently, the market is rich in products that have a low coefficient of flammability due to the addition of special flame retardants.
It does not change its physical properties in a wide operating temperature range - from -50 to + 85 degrees.
Among other significant advantages are:
- Environmentally friendly material;
- Is an unfavorable environment for the reproduction of fungi, mold and pathogenic bacteria;
- Resistant to chemical agents;
- The density of the material is 33-38 kg / m.cube;
- Easy to use and lay.
Foamed polystyrene foam for the warmer floor has become increasingly popular.
Its distinctive feature is a metallized coating that is placed on both sides of the thermal insulation material.
One of the advantages of this type of expanded polystyrene is durability. According to the manufacturers, it is able to serve more than 70 years with the operating range from -40 to +40 degrees.
The foamed protective layer makes the heat insulator resistant to solvents and other corrosive media.

However, without the addition of flame retardants, it is referred to easily combustible materials( ignition temperature - modest 210-220 degrees).
Therefore, it is recommended to buy material at the end of the brand which is the letter "C".
We proceed to laying
Before laying a warm floor on a concrete floor or cement-sand screed, it is necessary to draw up a work plan and strictly follow it.
Styrofoam can be laid under the warm floor with your own hands, as the technology of the work is very simple.
At first, the floor must be laid logs of wooden beams. It is generally recommended to use a 10x10 cm beam, but if the height of the room is insufficient, you can use a 5x5 cm beam.
The wood must be flat and dry, soaked in antiseptic substances.
The next step is laying the substrate between the lags. It is recommended to use a polyethylene tape, which is used as a lining under the laminate.
It is recommended to lay foil extruded polystyrene under a warm floor, which will act as a kind of screen that reflects heat back into the room.
They are covered with the whole area between the lag. Then, over the insulation will be laid pipes made of metal-plastic, through which the coolant will flow.
It is recommended to make a small distance between the lags - from 50 to 80 cm.
In order not to be mistaken and not to cut the heat insulator in the future, do not damage its structure, first they buy the material and adjust the size bars to fit it.
All logs should be laid in one plane so that the clean floor surface is flat.
From the edges, the substrate is wrapped on the side of the log and nailed using a stapler or small galvanized nails.

If the concrete floor base is not in perfect condition( many depressions, hillocks, cracks and chips), it is necessary to improve it.
Today, the expanded polystyrene foam for the warm floor is widely used.
Its main feature is the presence on the surfaces of protrusions, through which pipes with coolant are passed. It excludes their longitudinal and transverse oscillations.
Market prices
Nowadays it is possible to buy expanded polystyrene for the warm floor in the shops and in the markets.
It is recommended to trust manufacturers who have proven themselves among customers for many years.
Today, the price of expanded polystyrene for the warm floor can fluctuate in a very wide range.
The cost of one square meter starts from a modest 25 y.e., However, the materials of famous manufacturers can reach in price up to 150-200 y.e.
