How to insulate the floors in the apartment? Insulation for wooden floor. Warm floor

The problem of the cold floor is now found in many apartments, especially those located on the ground floors. In order to protect the premises from cold air and moisture that go from the ground or basement, many are thinking about how to insulate the floors in the apartment. To do this is not difficult, in addition, modern manufacturers offer a wide range of building materials that make the process of warming operational, convenient, simple and economical.

Step one - select the material

Modern materials provide ample opportunities for the competent arrangement of their housing. As a heater, experts advise the use of expanded polystyrene, expanded polystyrene, expanded clay, mineral wool or fiberglass, cork or cellulosic material. All of them can be divided into natural, that is, natural, and artificial. Distinguish these materials and the manner of application. For example, expanded clay, granulated slag and foamed glass are poured onto the surface, liquid foam or eco-wool is sprayed, and the polymer mixes the floor. However, most often in the search for a solution to how to insulate the floors in the apartment, resort to the use of roll materials that are easy to install. These are mineral wool, linoleum, linen, isolon, cork or penofol. No less popular for insulation tile materials.

Step two - determine the technology

An important issue is the choice of technology for floor insulation. For example, if claydite, mineral wool or penoplex is chosen as insulation, lagging or installation of the screed will be required. If roll materials are used, they are simply rolled out on the floor, after which the top is covered with a hard finish material, for example, wooden parquet, laminate or linoleum.

The minimum amount of space is concealed by polymer floors, which are thermal insulation mixtures. On the other hand, many people are looking for ways to insulate the floors in an apartment cheaper, and therefore polymer coatings are not suitable for all due to their high cost.

Step three - we produce competent calculations

Before choosing the building materials for insulation, it is worth to measure the area of the coating, to find out the height of the ceilings in the room. In a spacious room you can use almost any insulation, otherwise you will have to work hard and choose a material that will not hide the extra centimeters of useful space. An important role is played by the humidity level in a particular room, which is subject to finishing. For example, cellulose, flax, GVL sheets can not be used to finish rooms with high humidity, and such material as glass wool requires additional waterproofing.

How to insulate the floor on the ground?

How to insulate the floors in the apartment? This can be done in many ways, but many people choose this option. Its feature is the contact of the floor and the thermal insulation layer with the ground, and therefore you need to choose a heater that is resistant to moisture. If the house has a basement room, then you can confine yourself to a thin layer of thermal insulation. To insulate the floor, level it and then assemble the flooring, first it will be necessary to form a bulk layer, for example, from gravel or slag, which is then rammed. From above, the deck is fixed with lags, the spaces between them are covered with expanded clay or granulated slag. Depending on the type of climate, you can choose a variety of materials for soil insulation - from polyurethane foam and foam glass to expanded polystyrene and mineral wool.

Process Features

In most apartments, the floor is a screed made of concrete that is unlikely to retain heat. Since it is possible to insulate the concrete floor with the help of different building materials, it is worth starting to orient in a wide variety of options. Most often, foam polystyrene, extruded polystyrene, mineral wool or ecowool are used for this, as well as various kinds of liquid heaters. Above, the coating is finished with plywood, boards, laminate, parquet or linoleum. Sometimes, as an alternative, a combination of expanded polystyrene and a cement-sand screed is used.

Concrete overlap is well insulated with a dry screed based on expanded clay or gypsum boards. In this case, the thickness of the "pie" should be at least 7 cm. If the surface is flat, then you can limit the thickness to 2 cm - this will save useful space. You can insulate the floor with foam: this material is inexpensive, but it provides effective thermal insulation properties of the future floor covering. Popular and this way of warming, when sheets of fiberboard are used: with their help you can create a flat surface.

Arrangement of wooden floors

In the presence of wooden floors, it is advisable to deal with their insulation on the basis of lags. This is the simplest and most effective way to significantly reduce heat loss. This method is especially relevant for the insulation of floors that are located close to the ground, for example, on the ground or ground floors. To make a warm floor, you must follow a certain technology:

1. Wooden lags are installed in the foundation in increments of 0.6-1 m.

2. Bottoms are sewn on the boards.

3. The insulation material is laid on the flooring.

4. The next stage requires the laying of hydro- and vapor-insulating layers.

5. At the final stage, the floorboards are mounted, after which the flooring is finished.

The most demanded insulation for a wooden floor is mineral wool or fiberglass, which are protected from above by a layer of vapor barrier material. In some cases, builders recommend the use of sawdust, polystyrene or expanded clay - the choice depends on the preferences of each buyer.

Sawdust: the pros and cons

Choosing how to insulate the concrete floor, many are guided by roll materials, which are more convenient and easy to use. In the case of wooden houses, everything is not so simple, as most are looking for the most profitable solutions. For example, the most common method of insulation is sawdust, which is characterized by low cost, easy filling, even in hard-to-reach places, and also ecological purity. An alternative can serve as wood blocks, based on not only sawdust, but also cement, and copper sulfate. Popular for the warming of arbolite, which is obtained by mixing cement, organic aggregates and chemical additives. The plates are incombustible, easy to handle and highly resistant to bending, and they are not very resistant to moisture.

Cheaper or more expensive?

For many in the selection of building materials, the affordable value is crucial. In the same way, and a heater for the floor. The price for many building materials is low. For example, the universal method of heat and sound insulation of the premises is the use of sheets of fiberboard, which cost an average of 150-280 rubles per square meter. Foamed polyethylene "Tepofol" will cost about 500-600 rubles. For products with an average level of cost can be attributed roll heat and sound insulation URSA - it can be purchased for 1200-1500 rubles. And the most expensive are rightly considered such materials as extruded polystyrene foam and liquid heat insulation - the cost of these materials starts from 3000 rubles per square meter.
