Floor insulation in the apartment: the most popular ways

Paul is the coldest plane in the apartment, and this is a fact. Even with proper heating of the room, the floor will always be heated below the air temperature. And this is normal from the point of view of the laws of physics. But does not always contribute to comfort and comfort in the apartment. Therefore, people in most cases cover the floors with carpets, carpet, linoleum and other floor coverings in order to at least somehow increase the temperature of the floor. It is known that the cold air is harder and, accordingly, lowers down, so it can also penetrate through poorly baked inter -sequinus joints at home, raw basements and corner gaps. Each self -building expert will say that up to 30 % of heat goes through the floor. Naturally, people begin to more intensively heat the apartment (thermal cores, air conditioners, converters, etc. D.), accounts are growing, and in the apartment it was as cold and remain. The only correct and most effective solution will be high -quality floor insulation, which will reduce heat loss and improve comfort in the apartment.

Types of insulation materials

Ceramzite floor insulation

The floor insulation in the apartment occurs due to the use of materials with high thermal insulation characteristics, that is, they retain heat as much as possible and prevent its exit beyond the dwelling. The most used are:

Fanding (arbolite, expanded clay, chips) – have high thermal insulation indicators and a low price;

mineral wool and glass wool – have excellent warmth – and soundproofing properties, are not exposed to fire, hygroscopic, are not infected with mold and fungi, as well as inedible for rodents.

Polistyle and polystyrene foam – bad thermal conductors, moisture – and fire resistant, do not deform under the influence of external factors, and also perfectly absorb nois.

Important! It is impossible to distinguish the best material from this triple, since the choice of the heat insulator depends on the condition and type of floor, which must be insulated. That is, each material has its own specific purpose.

Warming of wooden floors

Sexual pie – as an option

The traditional method of insulation of the wooden floor involves laying the heat insulator into the space between the lags. To do this, first it is necessary to remove the flooring, if any, and open the floor (tear off the boards from the lag).

Then, an important point is the flooring of a vapor barrier layer (polyethylene or polypropylene film). The material is laid over up to 20 cm, and the seams are qualitatively glued with a two -sided adhesive tape, and the film is also raised to the walls to a height of up to 10 cm. Such a measure is necessary to prevent moisture from entering the thermal insulation layer from the outside.

Then you need to cover the insulation. For wooden floors, they are equally good like expanded clay, so mineral wool. The only question is how much the owner of the apartment is able to spend money. Proper insulation of the floor with expanded clay (mineral wool) implies a thorough filling of the inter -lane space used by the material. The work should be done so that there is no layer of air on the floor anywhere, otherwise the loss of heat is guaranteed, although not in the previous volumes.

The next step is to lay vapor barrier on top of the heat insulator. This is necessary to prevent moisture from the apartment.

At the end, it is necessary to cover the floor with boards again. If old boards have no flaws and damage, then they are quite suitable for further operation. If the boards were turned into dust in places, and when walking, the creaks were noticed, then the flooring is recommended to be replaced. Typically, experts use OSB sheets or a dense plywood, but if the means allow, then of course the use of new, even and soaked in a special solution (protection against parasites and mold) of the boards will be the perfect option.

The final stage is the installation of the flooring, which it will decide already the owners of the apartment.

Insulation of concrete floors

In most city apartments, the insulation of the concrete sex is the most urgent issue. If you add more cracks between them to cold slabs, then the floor becomes just icy time. Therefore, the first thing to do is to warm the floor, otherwise living in a multi -storey building will be simply unbearable. The term floor insulation, each master implies in his own way and personally tries to derive the perfect formula for solving this problem. Consider the most effective methods of thermal insulation of cold floors.

Option No. 1

The insulation of the floor of the first floor or tenth is not particularly different, the main thing is to do everything correctly, observing the technological sequence and using high -quality materials. It is possible to significantly increase the thermal insulation of the floor in a multi -storey building by laying the insulation between the concrete screed and the inter -story floor slab. First you need to get rid of the old cold screed, to clean the surface of the slab from garbage and eliminate irregularities.

Important! Before laying the insulation, it is necessary to tighten vapor barrier material – polyethylene or polypropylene film. It is preferably a whole piece without cuts and holes, but also lay vapor barrier overlap with stripes up to 20 cm. The seams must be glued with double -sided adhesive tape, and the edges should be brought to the walls to the height of the screed.

Next, it is necessary to lay the thermal insulation material (polystyrene, isuver), then cover it with another layer of vapor barrier and begin to reinforce the screed. It is necessary to lay a metal mesh along the area of ​​the room and using the wire to knit its sheets among themselves. When this work is done, you can start filling the screed. Minimum thickness of the concrete floor – 5 cm. After drying out to fully strengthen the upper layer, it is advisable to open it with a layer of special primer, on which any decorative flooring can be covered in.

Option No. 2

In this case, the insulation of the concrete floor is similar to the wooden one, only it is necessary to lay the lags on the concrete floor, cover the insulation between them, but the end of the wooden floor on the lags will be the ending action.

Pay attention! First of all, it is necessary to cover the vapor barrier film, and only then can you begin to carry out the above operations.

PPU spraying

Floor insulation in the apartment of PPU

Today, one of the most effective and common methods of floor insulation is the spraying of a layer of polyurethane foam. To carry out such a procedure, a special installation of high pressure is necessary, so such insulation of the floor with your own hands is not always possible. A PPU layer is applied to a pre -prepared concrete surface. When interacting with oxygen, polyurethane foam is foamed and turns into a porous homogeneous mass, which is an ideal heat insulator. Thus, you can insulate not only the cold floor of the apartment, but the basement of houses, a garage, industrial buildings and the like. PPU does not ignite, does not emit toxic gases, environmentally friendly and not edible for rodents, cockroaches and mold. In addition, when using polyurethane foam, vapor barrier is excluded, since PPU is also an excellent waterproofer.

Alternative floor insulation

If the heat loss through the floor is not so large, but still, when frost, you have to dress warmer, there is a sufficient simple, but often effective solution. The first thing you can do is buy a carpet and cover it in a room. The possibility of using carpet or linoleum of a compacted concept is also not excluded. These floor coverings hold heat very well and are very practical to use. In extreme cases, it is necessary to remove the existing floor covering (laminate, linoleum, parquet, etc. D.) and cover a special foamed polyethylene on a concrete base. This material is a wonderful heat insulator that does not require large investment. The main thing is to put it evenly on the floor and again install the flooring again. The effect will be instant. More sophisticated residents have their own idea of ​​the “warm field”. Having a special soldering iron for plastic pipes, they solder the pipes in such a way that the result is a coil or spiral. The entrance and output of the “warm” floor is connected to the general heating system (centralized or autonomous). A screed is poured at the end, and then a decorative flooring is mounted. Having such a floor, no frosts are no longer afraid.

We suggested that you choose. We only want to note that we talked about the most popular ways of warming the floor in an apartment, repeatedly tested in practice. With the right work, thermal insulation of the penis will really be effective.
