Noise insulation of the floor in the apartment. Soundproofing of apartment: price

Noise insulation of the floor in the apartment is arranged usually in the event that at the bottom live restless neighbors. Sometimes it is necessary and in order to exclude the penetration of sounds and to the residents of the lower floor. You can arrange it using a variety of materials. Today, you can find quite inexpensive and very effective sound insulators on sale.

Types of noise in the apartment

In modern apartments and houses can penetrate only two types of noise - air and shock. In the first case, residents hear the conversations of neighbors from the bottom, the work of their TV, tape recorder, the sounds of cars passing by the house, etc. Shock is the noise penetrating through the structure of the building. This can be the slamming of doors, the trampling, the roar of the elevator, etc. And from that and from another type of noise, most often get rid by coating the surfaces with mineral wool or styrofoam.

Methods of soundproofing the floor of apartments

Noise insulation of the floor in the apartment can be performed in several different ways. The simplest is the laying of the acoustic pad under a finishing coating. As the latter one can use, for example, isolone. There are varieties of this material, designed specifically for sex. However, such a variant is not particularly effective. All that can be achieved using a soundproof gasket is to muffle the sounds of your own steps while moving around the apartment and, accordingly, to get rid of this kind of shock noise from neighbors from the bottom. In order to soundproof the room thoroughly, it is worth using materials such as mineral wool or styrofoam. So-called floating floors are used. The features of the technology of the device of this type of soundproof pillow will be considered a little lower. First, let's try to understand the advantages and disadvantages of mineral wool and expanded polystyrene.

Advantages and disadvantages of mineral wool

Noise isolation of the apartment is very often arranged with the use of mineral wool. Its merits include:

1. High degree of sound insulation. Due to its noise-absorbing properties, the mineral wool significantly exceeds many materials.
2. Ease of installation. It will not be difficult at all to polish the floors with basalt slabs.
3. Low cost. Worth mineral wool is much cheaper than most other soundproofing devices (including expanded polystyrene).
4. A light weight. Plates of mineral wools can easily be raised to any floor. In addition, they do not overload the structure of the floor.

The disadvantages of mineral wool can be attributed primarily to the fact that it is afraid of high humidity. Therefore, it is not recommended to use it for floor insulation in damp areas.

Pros and cons of using expanded polystyrene

Noise insulation of the floor with your own hands can be performed with the use of expanded polystyrene. Apply it quite often, because, firstly, it absorbs noise (95%) perfectly, and secondly, it is not afraid of moisture. In addition, polystyrene foam is lightweight and easy to install. The disadvantages of this material include, first of all, its combustibility. In rooms with an increased risk of fire, it is best to use mineral wool. Also it is not recommended to forgive them for floors in private houses. The fact is that mice are very fond of gnawing this stuff, doing moves in it and arranging burrows.

Features of the construction of the "floating floor"

The main feature of the "floating floor" design is the absence of a rigid bundle between the sound and heat insulation cake of the floor and walls. This solution allows you to protect the room not only from air, but also from shock noises. Since the floor screed in this case does not touch the walls, vibration of the sound simply does not come into it.

There is such a pie from several layers - waterproofing film, sheets of plywood, actually soundproof material, screed and finishing.

Floor insulation: materials

Sound insulation of the floor is made using the following materials:

In addition to these materials, you will need to prepare the following tools:

1. The rule for the device screed.
2. A construction knife.
3. Roulette.
4. Nails.
5. A hammer.

Sound insulation of the floor: the price

The noise insulation of an apartment, the price of which depends, of course, on the area of the premises, if it is performed independently, does not cost so much. Knowing what materials will be required, it will not be difficult to calculate the sound insulation price of the floor itself. Packing of mineral wool plates costs about 500 rubles. It is calculated approximately on 6м2 of the area. Accordingly, for warming the floor of a room of 30 m2, five such packages will be needed. Therefore, cotton wool costs 2,500 rubles. Calculate the amount of cement needed for the screed device is also simple. On a concrete layer 1 cm thick and an area of 1 m2, 20 kg of dry mixture of sand and cement (3 * 1) leaves. That is, for the device of a screed in 4 cm thick on an area of 30 m2 will take 2400 kg. To find out the amount of cement, divide this figure by 4, we get 600 kg. Standard bag weighs 50 kg and costs about 250 rubles. Thus, for 12 bags will take 3,000 rubles. This means that the sound insulation of the floor of the room in 30 m2 will take approximately 5500 rubles (excluding finishing).

Where to begin?

In order to noise insulation of the apartment turned out to be of high quality, the old floors will have to be dismantled. If the boards are in good condition, you can reuse them. However, more often owners of apartments at the same time change them. After the floors have been disassembled, you can start preparing the base.

Substrate preparation

Before the beginning of the work on the soundproofing of the floor, the surface of the floor must be carefully prepared. First of all, you should sweep away all dirt and dust. In the event that there are cracks or chips in the concrete, they must be cemented with cement mortar.

Installation of waterproofing material

The noise insulation of the floor in the apartment is usually carried out with its preliminary waterproofing. Polyethylene is not recommended for this. It is better not to stint and buy a special membrane that does not allow moisture from outside and passes it from the inside. The waterproofing film protects the heat insulator from getting moisture vapor from it from the lower floors or from the basement. Also, its use can prevent the deformation of the parquet or laminate due to increased humidity.

Mounting of the compensating tape

After laying the waterproofing layer, it is possible to start installing the compensating tape. Cut it out of the same material that will be used to soundproof the floor. Its width should be such that it protrudes slightly above the surface of the future screed. Lay it along the entire perimeter of the walls close to the ceiling. To glue such tape it is necessary and around communication pipes in the event that they are available.

Stacking plates

Before laying the insulation plates on uneven floors it is necessary to lay them with plywood. The sheets are staggered and attached to the slab by self-tapping screws. At the corners of the plywood fasteners must be screwed, as they have the property to bully. After this, you can start laying the slabs of mineral wool or expanded polystyrene. Elements of basalt insulation should be as close as possible to each other. Joints between plates of expanded polystyrene pass through mounting foam, and then they are glued with paint tape.

Screed device

Noise insulation under the floor screed gives a very good effect, and therefore is arranged quite often. In order for the concrete surface to be level, pre-level beacons are set up. Between them is laid reinforcing mesh. The solution is prepared from cement and sand in a proportion of 1 * 3. He is tossed between the lighthouses on the grid and leveled by the rule. The thickness of the screed should not be less than 3 cm. Once it is ready, you can start laying the finishing of the floor. In modern apartments is very often arranged noise insulation floor for laminate, linoleum, parquet or tile. The laminate on the concrete cover is laid in the usual way. Of course, the screed under it should be as smooth and smooth as possible. Not necessarily, but it is desirable to use a substrate.

Laying of linoleum on concrete

One of the most common options for finishing a concrete foundation is laying linoleum. It is best to purchase material on a felt basis. Attach linoleum to concrete with rubber bituminous mastic. Adhesive composition on the surface of the screed is applied with a notched trowel. The laying process starts from the corner, rolling the roll away from itself. Mastic should be applied to the underside of the linoleum. After the strip has been laid in place, it is rolled with a heavy roller, carefully leveling. If this step is skipped, then the surface of the linoleum will just bubble.

Sound insulation of the floor on the logs

Noise insulation of a wooden floor or even concrete is sometimes done on logs. This method is not as effective, but it is technically considered to be simpler. It is used most often in out-of-town single-story houses on a pile-and-grove foundation, that is, if there is no need to isolate the room from impact noise.

In this case, the old floor is simply nailed by the thickness of the soundproof material. Further, a waterproofing film is laid between them. On it the plates of a heater are mounted. Then on top of the bars on the logs a vapor barrier film is nailed. On the resultant controllable, an edging or a floorboard is mounted. At the final stage, the board is painted, varnished, or a finishing finishing material is mounted on it.

As you can see, the quality noise insulation of the floor in the apartment or in the house by oneself - the procedure is not particularly difficult. The main thing in the process of work is to observe all the put technologies.
