Floor insulation for concrete under the screed in the country, on the balcony, in the bath

In a private home the task of thermal insulation of the sex does not cease to be relevant. The owners of their dwellings are trying to solve this issue with the help of different materials, each of which has its own characteristics. In order to make the right choice, you need to familiarize yourself with them.

Use of expanded clay

A concrete floor insulation for concrete must have excellent sound and heat insulation characteristics, as well as strength, frost resistance and fire resistance. Many consumers pay special attention to durability and environmental friendliness. These properties have expanded clay. If you use a certain technology for insulation, even the coldest floor will obtain excellent qualities of thermal insulation. When using expanded clay, the laying of the waterproofing layer is more than relevant. Due to the fact that the described material has a high porosity, it is able to easily absorb moisture, which can cause unpleasant consequences. After laying the waterproofing it is necessary to spread the heat insulator. In order to achieve an ideal uniformity, the backfill needs to be fitted after installing the beacon guides. The first one is installed with an indentation from the wall by 30 millimeters. The subsequent elements should be mounted parallel to the first. There must be a distance between them, which will depend on the length of the rule.

Screed floor on expanded clay

If you choose a floor insulation for concrete for a balcony, then you can choose expanded clay. This is due to the fact that this material does not have an impressive weight, which is most relevant for the case described. Before pouring the final screed, it is necessary to work on the arrangement of the fixation layer. For this purpose it is necessary to mix water with cement. The result is a uniform suspension, which should not be too dry or too liquid.

This manipulation is necessary for the liquid mixture to fill all the full spaces and expel air. After the drying of this layer, a monolithic insulated floor is obtained, which will not be afraid of moisture and heavy loads. The final stage will be a screed for final alignment.

Screed solution

If the floor is insulated with concrete, it is important to prepare the grout properly. As the most appropriate ratio of cement and sand, the proportion is 60 to 40. The liquid should be added in an amount of 10-20% of the total weight of the dry mixture. Then all the ingredients are mixed, and the resulting solution is poured onto the expanded clay layer. At the next stage, the master should level the surface with a large spatula, the length of which is 100 centimeters.

Alternative solutions for insulation of concrete floor

If you decide to choose a floor insulation for 10 mm concrete, then you can choose polystyrene foam. It has excellent quality of thermal insulation, serves for a long time and has an affordable price. If you decide to equip the heated floor in the sauna , this solution acts as the optimal one. Expanded polystyrene can be laid on an old coating made of ceramic tiles, metal, wooden or concrete surfaces. The base is strengthened with thermal insulation, then reinforced mesh is mounted, only then you can proceed to the arrangement of concrete screed.

Features of the use of expanded polystyrene

Choosing a floor insulation for concrete, you can buy expanded polystyrene. Its insulation properties are 25 times better compared to claydite-concrete. Among other things, this technique is characterized by more pleasant sensations during operation. Due to the fact that expanded polystyrene is not afraid of moisture, it can be used for work on balconies, as well as in rooms whose conditions are characterized by a high level of humidity. Such insulation for the floor on concrete can be used for the arrangement of a floating screed.

Technology of work

In rough alignment, the use of slabs of different thickness is acceptable, but it is recommended to fill the screed before the floor device. This is true if the work is done on a balcony or a loggia. Then the waterproofing film is laid, followed by expanded polystyrene, and then the reinforcing mesh is mounted. Preliminary it will be necessary to apply a fixing solution, for this purpose it is possible to use a composition for arranging the screed. The layer should have a thickness of 2 cm.

At the next stage, a screed is poured in 5-8 cm. It is important to take into account that at the final stage it is necessary to repair technological gaps located along the perimeter. In this case, fiberglass or foam is used. When using a floor warmer for concrete expanded polystyrene, it is important to consider that the roll waterproofing is overlapped. Its width should be 10 cm. Individual bands should be fixed with adhesive tape. Then you can proceed with the arrangement of the floor covering.

Applying a Penoplex

Penoplex is a foamed polystyrene, which is characterized by low thermal conductivity and excellent noise insulation, as well as durability and moisture resistance. If there is a base with any design features and configuration, foam foam is the best option. After installation, the screed is arranged.

Thermal insulation of polyurethane foam spraying technology

If you need a floor warmer for concrete in the country, then you can prefer the now popular thermal insulation in the form of sprayed polyurethane foam. This insulation material is economical, and also characterized by short terms of work. After application, a smooth coating can be obtained, which is free of joints and joints. It is possible to single out other advantages of this technique, among them the possibility of equipping a floor of 100 square meters with the forces of one brigade. It should be noted and low transportation costs, this is due to the fact that polyurethane foam is supplied in special containers in the form of barrels, the volume of which is 200 liters. As a result, it is possible to obtain an insignificant layer thickness of 50-100 millimeters, which does not steal excess space.

If you decide to use such insulation for the floor on the concrete on the balcony, it should be noted that it does not imply the use of additional vapor barrier. Due to the unique structure, the material is not capable of forming condensate. When used by spraying, you can make insulation both inside and outside the building. In the latter case, we are talking about the insulation of cellars, facade walls, as well as structural joints, which are part of the overlap. Polyurethane foam is not afraid of exposure to mold, rodents, and temperature changes. The material can not be negatively affected by natural and climatic factors. After spraying of polyurethane foam, it is possible to lay any type of screed. If there is a need for warming the floor of the first floor, then the described technique is the most suitable solution.

Features of using sprayed polyurethane foam

Choosing a floor heater for concrete under the screed, you can prefer polyurethane foam, which has an insignificant coefficient of thermal conductivity in the range of 0.021 W / m * K VC. This characteristic makes the material a leader in its field. Spraying can be carried out on a surface that does not involve additional preparation. However, the master still needs to perform dedusting, which will increase the adhesion characteristics.

It should be taken into account that the adhesion quality of the polyurethane foam is 1-2 kg / cm ² , which looks impressive. It does not absorb water and is not able to pass water vapor, so there is no need to carry out additional moisture protection. Choosing a floor warmer for concrete in a bath, many owners of private houses face a problem that is expressed by the complexity of the configuration of the rough foundation. The described materials completely solve this problem, because they can be sprayed on any surface, and the structure will repeat the existing relief. In carrying out the work, it is possible to apply a thinner layer that will perform its tasks, which can not be said about a number of competitive materials that require the need for a longer layer. This allows you to save space, for example, in bathhouses, cottages, as well as on balconies and loggias.

additional characteristics

The above concrete insulation for concrete, the photo of which is presented in the article, does not require fastening elements, which could serve as cold bridges. You can use this insulation without worrying about the health of your loved ones, as it is environmentally friendly and does not cause allergic reactions. Manufacturers guarantee the life of the insulation, which lasts for 25-50 years, which will depend on the external conditions and factors that affect the material. Polyurethane foam is not a favorable environment for the reproduction of bacteria and fungi, in addition, this insulation is not of interest to rodents. After the work, you can expect to increase the soundproofing characteristics of the floor. During the work, it is possible to spray the material, the density of which can vary from 15 to 500 kilograms per cubic meter. The final value depends on the tasks.

Conclusion

Each of the insulating materials presented above has its own qualitative characteristics. The choice must be made only after you become acquainted with their properties. For example, if polyurethane foam is sprayed with a density of 50 kilograms per cubic meter, it will perform an additional function of the waterproofing layer. If there is such a need, then you can spray the material with these features. Then it will be possible to save on the acquisition of related materials.
