By doing overhaul In an apartment, you should not limit yourself to making an even screed on concrete slabs. An important question is a solution to the problem of installing a high-quality soundproofing layer.

The main goals of floor soundproofing are to minimize the noise level penetrating into apartments located on the floor below and protect against noise produced by neighbors below. Noise sources, their characteristics and noise standards are determined by SNiP 03/23/2003. This document was developed using the following regulatory documents: GOST 17187-81, GOST 27296-87, SP 23-103-2003, SNiP 2.07.01-89.

The traditional way to solve this problem is to lay elastic materials: linoleum or carpeting. However, the issue can be completely resolved high-quality sound insulation floors from lower neighbors in this way is impossible.

The “floating floor” system is one of the floor soundproofing options

One of the ways to solve not only the problem of floor sound insulation, but a number of other, no less important problems, is the “floating floor” system.

The term “floating floor” means a multi-layer flooring, which does not have a rigid connection with the ceiling. The elastic materials used in the design effectively absorb vibration and prevent sound transmission to the room below.

Although there are quite a few options for installing a floating floor using a wide range of materials, there are three main types: concrete floating floors, prefabricated and dry screed.

A logical question arises: why use such a fairly complex system, if there are traditional, more simple ways soundproofing devices? The reason for the popularity of floating floor technology is due to the following reasons:

• This most effective floor soundproofing technology.
• One of the layers of the floating floor is thermal insulation material, most often mineral wool, which allows you to increase the level of heat conservation in the apartment.
• “Prefabricated floor” and “dry screed” technologies simplify and speed up the process as much as possible. installation work, since they are carried out without labor-intensive “wet” processes.
• The use of such a soundproofing system makes it possible to install heating elements electric or water “warm floor”.
• Floating floors can be installed both during construction and renovation.
• The system perfectly solves the issue of eliminating floor unevenness.

Construction of a concrete floating floor

This type of soundproofing floor covering is a strong, reliable, durable base.

Concrete floating floors are installed in rooms with significant loads on the floor - in warehouses, garages, parking lots. This technology is also suitable for installing a warm water floor, since good thermal conductivity of the top layer of the structure is important for it.

The procedure for performing concrete floating floor technology:

1. The base is cleaned, unevenness is first eliminated - depressions are sealed and bulging areas are removed.
2. For the purpose of waterproofing, bitumen mastics are applied to the base or special dry mixtures are used.
3. Edge tape is glued along the contour of the room.
4. If mineral wool is used for the cushioning layer, then a vapor barrier must be laid on the base with mandatory gluing of the joints.
5. A cushioning material is placed on the prepared base, which is mineral wool or polystyrene foam.
6. A polyethylene film is placed on top of the cushioning layer, which will serve as a separating layer between wet screed and laid sound and heat insulation layer.
7. Then pour cement-sand mortar, the quality of which can be improved with the help of special additives. Screeds are used for reinforcement metal mesh.

Floating prefabricated floor technology

This type of floor includes coatings made from parquet or tongue and groove boards or laminate.

These coatings must be laid through cushioning material on a level base, since unevenness will lead to deformation of the material and their rapid failure. Minor flaws, such as scratches, are acceptable.

An insulating material is placed on the base, which is most often foamed polyethylene with a uniformly closed cellular structure. Foamed polyethylene can be used for all types of floor coverings, and is available in two types:

• physically cross-linked (or gas-filled) polyethylene foam;
• chemically cross-linked polyethylene.

The second option is polystyrene foam. The thickness of the insulating material is 2-5 mm.

Elements of the finished floor covering are laid out at a distance of 10 mm from the wall. This gap is necessary so that when the coating expands under the influence of temperature, it does not swell, resting against the wall.

Prefabricated floating floors are least effective in terms of sound and heat insulation.

Dry screed technology

The installation of a floating floor of this type eliminates the use of solutions. This method involves leveling the surface for subsequent laying of the prefabricated floor. The difference between this soundproofing technology and a concrete floating floor is that dry mixtures of fine-grained materials, such as expanded clay or perlite sand, are poured onto the base.

Dry backfill allows you to quickly level the base on which the remaining layers are laid. This method is much cheaper than concrete floating floor technology.

Stages of dry screeding:

1. The base of the floor is prepared by removing all old coverings. The cracks and recesses are sealed with a solution prepared from a dry mixture. For this purpose, you can use Remstream-T.
2. Using a laser or water level, mark the height of the bedding.
3. An edge strip is fixed between the wall and the future bedding, for the manufacture of which foamed polyethylene or mineral wool is used.
4. Since fine-grained bedding has low moisture resistance, it is necessary, in order to create moisture protection, to spread a plastic film over the entire area with an overlap of at least 250 mm at the edges. The edges are glued with reinforced tape.
5. The bedding is laid to the marked level and compacted.
6. Most often, gypsum fiber boards are laid on the bedding in two layers, fastened together with glue.

This is one of the most simple options dry screed technology.

If the initial task is to create reliable thermal protection, then polystyrene foam or extruded polystyrene foam can be additionally laid on the bedding. If the main goal is sound insulation, then mineral wool is used.
The maximum thickness of polystyrene used for these purposes is 100 mm. To soundproof the floor of the second and subsequent floors, as a rule, polystyrene foam boards 30 mm thick are used.

Cork soundproofing underlays

Traditional options for floor soundproofing are the use of a substrate under the finishing flooring, which performs three main functions: smoothing the surface of the base, sound insulation and heat insulation.

A practical substrate for laminate or linoleum is cork material, which has a cellular structure. Small air bubbles located in millions of cells of the cork structure ensure uniform load distribution over the entire floor area. This is an excellent material for heat and sound insulation. In addition, the cork substrate is resistant to high humidity in the room, which allows you not to worry about its possible deformation.

Based on natural cork chips they produce following materials for floor soundproofing:

• Sheets made from cork chips are not subject to rotting, mold formation, and are not destroyed by rodents. This chemically inert material has a service life of at least four decades and reduces noise levels by 12 decibels.
• The cork rubber backing is made from a mixture of granulated natural cork chips and synthetic rubber. Can be used under all types of floor coverings. Requires additional moisture protection devices using polyethylene film. Has the maximum among cork materials noise-absorbing characteristics - reduces the noise level by 18-21 decibels.
• The bitumen-cork substrate resembles appearance roofing felt with crumb topping. Such a substrate is laid with the bitumen layer up and the cork down. Does not require additional waterproofing, noise reduction level reaches 18 decibels. The main disadvantage is the difficulty of laying on the base.

Other types of materials for sound insulation

Prices for materials for soundproofing floors

If you are in doubt which sound insulation for the floor to choose without compromising family budget, see in the table the cost of the materials indicated in the article and some other materials (prices for March 2019 for Moscow), as well as the reviews below:

Soundproofing the floor: reviews

You can watch a brief overview of the properties and use of materials for soundproofing floors in an apartment in this video:

Illiterate installation of even the most modern soundproofing materials can lead to a complete lack of effect from their use. Therefore, before starting work on soundproofing the floor with your own hands, it is advisable to get advice from a qualified acoustics specialist.

Unfortunately, apartments in multi-storey buildings have very low level soundproofing. This is especially true for buildings built from reinforced concrete panels. Not only do the interior wall panels themselves have a very small thickness, but their structural structure does not contribute to the absorption of sound, and some of their components even conduct it, for example, fittings. Therefore, soundproofing the floor in an apartment has become an urgent necessity for many.

Not so long ago it was very difficult, and sometimes almost impossible, to purchase materials for sound insulation, and apartment owners came up with different ways protect your home from loud music or emotional conversations of neighbors. Old carpets, leftover styrofoam packaging, and even egg trays were used.

Today at construction stores- a huge selection of different soundproofing materials, and craftsmen offer numerous ways to design a soundproofing system. To choose the option that is more suitable for a particular room, you need to consider the characteristics of some of them, and how they fit into the room. concrete floor.

Kinds sound insulators and how to install them

Not every soundproofing the material is suitable for a specific apartment. For example, to create a sound-absorbing system using wooden sheathing, you must have high enough ceilings. The sheathing will be at least five centimeters in height, plus the thickness of the plywood laid on top - and the volume of the room will be significantly reduced, the ceiling will be lower. Therefore, in this case, you need to choose materials that have a small thickness and, at the same time, greater noise absorption efficiency.

Soundproofing MaxForte

Floor sound insulation for floating screeds is made using modern MaxForte materials. Each material has its own installation characteristics.

MaxForte Shumoizol. The rolls are spread with the soft side on the floor, the edges are placed on the walls. After work, all excess can be easily cut off. The joints between the rolls are coated liquid rubber MaxForte Hydrostop.

« Texound »

Characteristics

Not long ago in Russian construction market a modern soundproofing material has appeared - “Texound”, which, it turns out, has been produced for more than twenty years, and during this time it has fully justified all the characteristics claimed by the manufacturer. With a thickness of only 3.7 mm, it is considered one of the best sound absorbers.

This is what Texound looks like in rolls...

This material is produced at mineral based and is ideal for flooring in residential areas. In addition to floors, it is mounted on ceilings and walls, thereby achieving maximum protection from noise, and at the same time minimizing the loss of area and total volume of rooms.

It must be said that Texound has a high density and, accordingly, significant mass, which is seven kilograms per m², therefore it seriously weighs down structures, which is important when placing it on walls or ceilings. But it was him high density and creates protection against noise penetration.

Positive and negative sides

The material has the following advantages over others sound-absorbing materials:

1. It is flexible and elastic, and also has the ability to stretch.

2. Its installation is simple and straightforward.

3. The material does not respond to temperature changes.

4. “Texaund” is not hygroscopic and is not susceptible to mold or rotting processes.

6. Ideally fits on any surface.

7. Has an unlimited service life.

8. And most importantly, it has a high absorption coefficient of airborne sound waves and noise.

The only disadvantage of Texound is that it must be used in combination with thin insulation or other material, i.e. To achieve the desired effect, it is not recommended to lay it on a concrete slab without a backing.

Texound

Installation

When arranging sound insulation, you always want to achieve the maximum effect, and in order to achieve this, you must act strictly according to the instructions and recommendations given by the manufacturer of the material.

Approximate layout of "Texound"

As mentioned above, Texound must be laid on a prepared base. Any sheet or roll insulation- it can be thin foam polyethylene - polyethylene foam, drywall, plastic or plywood. If the ceilings are high and it is possible to make sound insulation from a thicker layer, then mineral wool can be used for one of the components.

• The concrete slab is thoroughly cleaned with a vacuum cleaner.
• Next, the base is laid on it. If it is an elastic material, then it is better to secure it with glue.

Polyethylene foam will raise the floor by only three to five millimeters. The best option It still counts as drywall. This is because, firstly, it will make the floors perfectly smooth and cover the defects of the slab, and this will protect Texound from damage, and secondly, it itself is a good sound insulator.

• After the base is ready, coat it on top special glue, wait 10-15 minutes, and then carefully lay Texound, extending 10-12 centimeters onto the walls.

Spreading "Texaunda"

• When the material is laid, it is necessary to carefully connect the joints between the sheets using hot air or glue. The sheets must create an airtight coating, otherwise the soundproofing effect will be reduced.
• Next, “Texound” is covered on top with another layer of plasterboard or 10 mm plywood. In total, without decorative coating, the floors will rise by 23.7 millimeters.
• Any flooring can be laid on top of plasterboard. covering - linoleum, laminate, carpet, etc. - it will also create additional sound insulation.

If you increase the number of layers and use materials with different densities for them, the sound insulation will be several times better.

Mineral wool

Three types are used for sound insulation and insulation mineral wool- These are stone wool, slag wool and glass wool. They all can have different thickness and are produced in rolls or slabs.

Mineral wool can be of different densities, on which thermal conductivity and its ability to withstand external loads will depend. In addition, the material differs in its coefficient of moisture and heat resistance.

1. Stone wool

Stone wool is a heat-resistant material and can easily withstand high temperatures, reaching up to 500-550 degrees. This sound insulator is made from fibers obtained by melting rocks.

Rolls and slabs of basalt wool

Most best view stone wool - basalt, it is an environmentally friendly sound insulator, as well as excellent insulation. Another advantage is that it does not contain binders - formaldehyde resin, unlike some other types of mineral wool.

Basalt wool, produced in slabs and rolls, can be used for soundproofing work without installing the sheathing, since the material has a high density.

stone wool

1. Glass wool

This is the most affordable type of mineral wool, but it is more difficult to install due to the prickly fiberglass. Installation must be carried out with gloves and a protective mask on the face, since the thin hard fibers that make up the material dig into the skin and can get into the eyes and respiratory tract.

Most inexpensive option- glass wool

Glass wool has a lower density than stone wool, and it must be laid in a lathing. This kind of material is mainly used for non-residential premises, for example workshops, or for external insulation or soundproofing.

glass wool

1. Slag

This type of mineral wool is made from blast furnace slag and cannot be used in rooms with high humidity, since the material contains substances that, when interacting with moisture, will aggressively affect the metal. In addition, it cannot be used for external work, since there it will not be protected from moisture.

The material is hygroscopic, i.e. absorbs moisture well, which quickly reduces its quality. This material, in principle, can be used for sound insulation by laying it between the sheathing joists, but it is not advisable to use it in residential premises.

From the presented characteristics we can conclude that of the three types of mineral wool, only stone wool is ideal for soundproofing the floor of an apartment basalt wool.

Installation

Installation of mineral wool on floors for sound insulation is quite simple, and can be done in two ways: with or without the use of bar sheathing.

• The first thing to do with any soundproofing device is to prepare the surface of the base. All debris and dust are removed from it using a vacuum cleaner.
• Next, if on concrete the floor will be revealed cracks, they need to be widened and sealed cement mortar or a special repair putty, then allow these areas to harden well.
• Then it is better to lay a thin heat- and sound-insulating polyethylene foam on the concrete slab.
• If you decide to lay logs, then you need to correctly calculate the step of their installation; it must correspond to the width of the mineral wool slabs so that they fit tightly between the bars.

The bars are selected to be the same thickness as the thickness of the soundproofing material. After marking the floor, logs are attached to it; they should not be located close to the wall, but at a distance equal to the thickness of the insulation.

The next step is laying the slabs between the bars.

When all the material has been laid, they lay it on top plywood sheets They are secured to the sheathing bars using self-tapping screws.

If small gaps have formed between the sheets of plywood, they need to be sealed with wood putty.

After the putty has dried, linoleum, carpet or laminate can be laid on top of the plywood.

If you want to enhance the sound-absorbing effect, you can lay a cork covering on top of the plywood, which also has excellent sound-absorbing properties.

• Another option may be soundproofing without the use of wooden sheathing, and working on it installationcarried out in the following way.

Foamed polyethylene is also placed on the cleaned floor, which must be secured together with adhesive tape. This material should be found on the walls on the thickness of the entire soundproofing layer.

Along the walls of the entire perimeter of the room they place strips cut from mineral wool slabs, their height is about 15 centimeters.

Sheets of plywood or durable plasterboard are laid on the substrate, close to the sound insulator installed on the walls.

The next step is to lay the slab sound insulator close to each other. It is pressed as tightly as possible against the strips of material installed on the wall.

Another layer of plywood is laid on top of the mineral wool slabs and secured to the floor.

If small gaps have formed between the sheets of plywood, they also need to be sealed with putty.

After the putty has dried, you can proceed to installing a decorative floor covering.

As you can see from the description of the work process, everything can be done with your own hands, thereby protecting yourself from noisy neighbors living below.

Video - an example of soundproofing with mineral slabs

Cork soundproofing and covering

A material like cork is great sound insulator. It is made from decorative coating, which is laid according to the laminate principle. In addition, a cork underlay is produced, which can be laid under any decorative floor covering.

Cork flooring absorbs noise well in the apartment and reflects outsiders loud sounds from outside.

If we compare the level of noise protection of cork flooring with concrete wall, then its overwhelming advantage will be revealed - two cm of plugs can easily replace ten cm concrete slab or five cm of a wall built from pine beams.

With a two-centimeter thick plug, the sound level entering the apartment from the outside will be reduced by almost half. If you want to reduce noise more, then you can use cork as one of the layers of the soundproofing cushion, for example, when installing “Texound” - different densities of materials will help increase soundproofing Effect.

Decorative cork covering is of higher quality. It is produced in the form of tiles, panels and rolls. It can be used either separately from the cork backing or in conjunction with it to enhance the sound absorption effect.

Both options are an excellent protector from extraneous noise, but, in addition, cork is an excellent heat insulator, although it is small in thickness. The big advantage of this material is its environmental friendliness and the fact that it can “breathe”.

In order for the coating and substrate to work effectively, it is necessary to install them correctly.

cork flooring

Installation

Since the installation of a decorative coating and a cork backing can be done in a complex manner, they can be considered together.

The first thing to install, of course, is the cork backing. To install it, you need to prepare the surface, as for any other type of sound insulation. There should not be any debris left on the base, even small ones.

Under cork backing It is necessary to lay sheets of foamed polyethylene or other similar material. It should rise up the walls by 5-7 centimeters. The polyethylene is held together with special tape.

And he dealt with it.

Then sheets of plywood are laid on top of the cork and secured to the floor.

The selected decorative coating is laid on this solid base, which can be a laminate with cork covering or tiles of the same material.

Video - an original solution to the problem of sound insulation

In the presented video - very interesting way performing soundproofing of the floor using modern material with pronounced anti-vibration properties "Shumoplast". If it is possible to purchase, it is quite possible to do this work yourself.

When choosing sound insulation for a floor, you need to consider how much sound travels through the floors. The choice of material and its thickness will depend on this. In addition, you need to take into account the height of the ceilings in the apartment - if they are low, then you should choose a thin sound insulator.

What else you need to remember - if you want to make a room as noiseless as possible, you need to install a sound insulator not only on the floors, but also on the walls, and even on the ceiling.

Probably one of the most current problems modern multi-storey buildings, it's a constant noise. Of course, this issue can be resolved at the construction stage, but due to the cost, developers do not do this, leaving this problem to new residents.

Nature and sources of noise

The roar of cars can be heard from the street, and the neighbors also cause a lot of disturbance: some have a dog that constantly barks, others have children running around the house, and others suddenly started renovations and the list of irritants is only growing. The question of how to live quietly and calmly does not leave you.

There are a lot of modern materials and solutions that will help you. We will try to tell you in detail how to soundproof floors.

Most people who are thinking about soundproofing the floor in their apartment make the same common mistakes.

You should not ask others who do not understand this issue. Trust only professionals!

They understand exactly which material will help in a given situation, and which exactly should not be used.

Don't rely on carpets, paint, tall cabinets and so on. At most, they will help remove echoes, but will not get rid of sounds.

If you know exactly what kind of noise you want to get rid of, this will save you a good amount of money and the work itself will be easier and faster to carry out. Be sure to conduct a series of studies (we will talk about them in detail below) and determine where the sounds are coming from.

1. Airborne noise (neighbors talking, dog barking, etc.).
2. Shock noises (clamping in the apartment, sounds of moving furniture, etc.)
3. Structural noise (elevator sound, ventilation equipment and so on).

Once we have decided on the sources, we determine the oscillation frequency. It is for this that we select sound-absorbing material ( permissible load indicated on the packaging).

Next, we carefully inspect the apartment for cracks and crevices. They are more common panel houses, but it’s better to check brick ones too. Don't forget to check switches and sockets. Sometimes it is more expedient to make electrical fittings external rather than internal.

Any cracks found must be sealed before starting insulation work.

Innovative materials and methods

Let's consider two basic approaches to solving the problem of floor soundproofing:

Floating floor. We take sound-absorbing material and overlap it on the walls. It should rise above the level of the future screed.

In this case, our floor will not touch the walls. In this case, the screed can be used dry or regular.

This method provides maximum noise reduction, but there are several disadvantages:

Soundproofing substrate.

The work is carried out in two stages:

1. Level the floor.
2. We put the underlay and the floor covering on top.

Unlike the previous option, it provides weaker insulation. However, it will relieve you from household noise and loud neighbors.

This option is suitable for those who want to do everything quickly and without outside help, because... No special skills are needed here. There will be no additional load on the floors, and the price will please you.

Three most popular methods

Cork sound insulation.

The easiest and fastest option. Does not require huge financial investments and major repairs.

We purchase ready-made floor coverings and rejoice. They best absorb shock vibrations.

Most often used:

This option helps solve two problems at once: they eliminate extraneous noise and look beautiful, only polyurethane requires additional covering with flooring.

Insulation under self-leveling floor.

It's more quality option. First, we raise the old floor to the base. We make a floating concrete screed.

We carry out the work in several stages:

This isolation method is very effective, but there is a drawback. Such a structure will put a load on the load-bearing walls, so calculate everything accurately to avoid incidents.

Soundproofing a wooden floor.

Basic materials

In order to receive good result, it is important to choose the right material, focusing on its characteristics.

Let's look at the most popular materials.

Styrofoam- This is the most common material. However, it is important to remember that ordinary polystyrene foam will not work for sound insulation. It is important to remember that the denser and thicker the foam (up to 5 mm), the better the quality of work you will perform.

Expanded polystyrene– it is often used as Alternative option. It is more durable than foam and much lighter.

Minvata– in addition to noise insulation, it provides additional insulation. The material will last 40 years if you install it correctly.

However, when using mineral wool, waterproofing should be carried out, as it is very sensitive to water. Also, cotton wool will be a source of additional dust and synthetic resin, and this is a health risk.

Expanded clay– very inexpensive and safe, and will last a very long time.

Cork sheets– do not rot and eliminate shock and vibration noise well.

Foamed polyethylene– has very affordable price, and even a beginner can handle the installation. It is not susceptible to moisture and does not rot.

Perlite– is often used, but this is the most losing option. Thickness directly affects quality; the load on the house structure will increase.

Glass wool– very light and therefore ideal for houses from the old foundation. Perfectly absorbs noise from shocks and vibrations, and also ensures fire safety.

Innovative materials

Tecsound
. Does not respond to changes temperature regime and does not rot. It is unpretentious to install and will last a very long time.

When ignited, it goes out quickly, without outside help. It is important to remember that it cannot be laid without a backing.

Isoplaat – made from coniferous trees. Mainly isolates airborne noise (27 dB). Provides natural ventilation and is easy to install. However, this is quite an expensive material.

Noise stop – It helps well in the presence of noise from impacts (more than 39 dB). The advantages of this material include small thickness (20 mm), long service life and ease of installation. The biggest drawback is subsidence.

Vibrostek-V300 – It is made on the basis of fibers containing glass. You can purchase it in the form of rolls. Often used as a substrate, as its thickness is only 4 mm. Protects against noise up to 29 dB.

This is a durable material that can withstand heavy loads, naturally the price tag on it is high.

Isover suitable for wooden floors. Isolates sounds up to 38 dB. A relatively inexpensive material, it has low thermal conductivity, but absorbs moisture very easily.

Maxforte – can withstand moisture for a couple of hours, which eliminates the need to install additional waterproofing.

Rolls can be installed both under self-leveling floors and under floor coverings. Absorbs noise from impacts up to 27 dB. Withstands temperature fluctuations from -25 to +85 C. It will last you quite a long time, but it is not very attractive to rodents and insects. Refers to expensive materials.

Soundproofing – is a lining material. Absorbs noise up to 23 dB. It is a waterproof insulator and does not rot. The price tag will pleasantly surprise you, because with all its advantages, the price is reasonable.

Schumanet – it is a kind of fiberglass made of many layers. Absorbs noise up to 23 dB. Has good waterproofing. Very durable material, with relatively little large thickness. Does not ignite.

Remember that this material can only be installed at above-zero temperatures

In any apartment building, even if it is built according to the most modern technologies, structural elements of the floor, in contact with ceilings, walls, water supply and heating pipes, become conductors of sounds and noise from steps, moving furniture, falling objects. Any room in the apartment, be it a bedroom, children's room, home theater, living room or kitchen, must remain private for the owners and not create discomfort for neighbors, and reliable sound insulation of the floor in it is one of the main conditions for ensuring comfort. For this, between everyone structural elements A layer of sound-absorbing material is laid on the house and floor, which dampens noise and prevents its spread.

The construction market offers a variety of natural and synthetic materials, which provide good sound insulation gender and improve acoustic characteristics premises. Among noise-absorbing materials based on natural fibers, the most popular are:

• kaolin and basalt wool;
• stone wool based on various rocks;
• fireclay;
• expanded perlite;
• foam glass.

Mineral wool is one of the most popular insulating materials that prevents the penetration of not only sound, but also heat waves

Besides the beautiful soundproofing properties, all types of mineral building wool are endowed with other important properties in construction:

• fire resistance;
• vapor tightness;
• hydrophobicity;
• environmental Safety;
• durability.

The disadvantage of mineral wool is the thickness of the slabs from it is from 25 mm, and therefore in cases where every centimeter of the height of the room is expensive, or for other technological reasons, good sound insulation of the floor in the apartment is ensured using such synthetic roll materials as:

• polyester foam;
• polyurethane foam;
• polypropylene foam;
• polyethylene foam.

Materials created from foamed polyurethane perfectly prevent the passage of sound negative due to the presence in the structure large quantity air-filled "bubbles"

According to their structure, sound-absorbing materials are:

• porous;
• perforated;
• membrane

The porous group includes the most popular foam glass, aerated concrete, fibreboards, all types of construction wool. To soundproof floor structures, you should choose materials with a porosity of 80% and a pore diameter of no more than 1 mm.

Membrane soundproofing material creates a strong, dense barrier to the passage of sound waves, the energy of which is spent on overcoming this obstacle

Membrane materials include materials in which a reduction in sound intensity is achieved by expending energy to overcome forced vibrations. These are sheets of plywood, thick thick cardboard, soundproof fabrics.

In perforated materials, the propagation of sound is prevented by air-filled cavities and holes. These include sheets of perforated gypsum, asbestos cement, etc.

Methods for soundproofing floors

The most modern, effective, environmentally friendly and easy-to-use way to reduce noise levels in apartments and private residential buildings is a “floating floor” design.

The floating floor system is the most effective method soundproofing

It got its name because a floor structure of this type consists of several layers and not a single element of it comes into close contact with the surfaces of the interfloor ceiling and walls, and therefore does not spread sound waves to them or receive sound waves from them. There are three types of "floating floor":

• floating concrete pavements;
• floating dry screeds;
• floating prefabricated floor coverings.

Floating concrete pavements

This method is ideal for cases where, in addition to noise-absorbing properties, increased strength and high thermal insulation properties base and high thermal conductivity of the finishing floor covering, for example, when installing a “warm floor”.

Laying down floating concrete covering, the floor concrete is covered with a layer of moisture-impermeable thick film, on which the soundproofing of the floor under the screed, most often mineral wool, is laid. It is important that a layer of noise-absorbing material is laid not only on the concrete floor, but also along the contour of the room, laying an edge strip of it along the walls. Thus, the concrete screed seems to float or float independently of the base and walls. The width of the edge tape should be greater than the final height of the floor structure, and after completion of the work, its excess is cut off with a sharp knife.

A reinforcing metal mesh is laid on top of the insulating layer, beacons are placed and a concrete screed is poured over them.

Advice: Due to fast setting concrete mixture it is prepared in small portions and immediately poured, but in one room it is necessary to screed within one day. In two or more steps over several days, you can pour the screed in rooms with differences in floor height, while leaving space between the individual fragments of the screed. expansion joints width of at least 10 mm.

If there are slopes and other flaws on the surface of the base, it is leveled using a layer of fine expanded clay or sand. To prevent the floor from sagging over time, the backfill is compacted to maximum density.

The final flooring can be laid only after the screed has completely hardened, that is, after 4-5 weeks. The design of a floating concrete field significantly increases the load on the floors, its thickness reduces the height of the room, and therefore its use is not always possible or advisable.

Dry screed - floor soundproofing

Dry screed is an effective, quick and easy-to-use method of creating a “floating floor” and increasing its noise-proof characteristics. Before soundproofing a floor using this technology, you need to choose the right sound-absorbing material. Mineral wool slabs have the highest index of noise reduction from impacts: with a thickness of 20 mm they dampen 46.5 dB.

A vapor barrier and mineral wool material are placed on the concrete base, and backfill is placed on top, compacting the layer tightly and leveling it along the beacons. Along the perimeter of the room along the walls, an edge strip made of sound insulation material with a thickness of 20 mm and a height exceeding the final thickness is attached future design floor. The excess is cut off with a sharp knife after finishing the work.

Gypsum fiber boards are laid in two layers on top of the backfill layer, making sure that the gap between the wall and the slab is at least 10 mm. The slabs of the second layer are laid with a shift relative to the first so that their butt seams do not coincide. The gypsum fiber layers are glued together with PVA glue and then fastened with self-tapping screws. The length of the screw must correspond to the thickness of the two layers of coating so that it does not extend beyond its limits.

This option for soundproofing floor structures is very popular, since installation is carried out without the use of concrete and “wet” stages, all elements of the “layer cake” participate in sound absorption, and the final floor covering can be laid immediately after laying the last gypsum fiber sheet. The thickness of the floor structure on a dry screed does not exceed 30-40 mm and almost does not reduce the height of the room.

Prefabricated floors - soundproofing option

This type of “floating floor” includes laminate, parquet, tongue and groove solid board and other similar coatings equipped locking system"tenon and groove".

On a carefully prepared, perfectly level base, first floor sound insulation under laminate or parquet is laid, and then covering panels are mounted on it with a gap from the walls of at least 10 mm. Elastic polyethylene foam with a closed uniform cell system, expanded polystyrene or cellulose sheet materials are used as sound insulation, but they provide minimal sound-absorbing effect and largely play the role of a substrate.

To enhance the sound insulation characteristics of a laminated or wooden floating floor, a cork substrate or a special soundproofing membrane Texound is laid on the polymer layer, a layer of plywood is laid on it, and only after that the finishing floor covering is installed. The thickness of the soundproofing layer in such systems does not exceed 2-5 mm, which does not at all affect the height of the room.

Important: Regardless of the method of soundproofing the floor structure, the baseboards should be attached to only one surface: either to the wall or to the floor, placing cork or cork under it or in the gap between it and the wall. rubber gasket. It is not recommended to use nails, since metal is also a conductor of sound.

We hope you are convinced that soundproofing a floor with your own hands is a task that can be done by anyone who has basic skills construction work. You just need to be patient and choose the best way and the corresponding noise-absorbing material, and, having completed the work, enjoy the peace and tranquility in the apartment.

The modern world is filled with a variety of different sounds and noises. The constant impact of these irritants on the human body leads to stressful conditions. Only when you come home can you relax, unwind and truly enjoy the silence.

Modern soundproofing methods will help create the most comfortable living conditions without extraneous noise, both in a private house and in an apartment.

Application of soundproofing materials

Almost all materials used in construction have the ability to suppress external noise, but it is quite low. Therefore it is recommended to use Additional materials for sound insulation, capable of creating silence and the most comfortable conditions.

Initially, you should make sure that there are no holes or cracks in the surfaces of the walls, floors and ceilings. A high level of sound insulation of the floor in an apartment can be achieved by increasing its thickness through multilayer structures.

A competent combination of several types of soundproofing materials will create the maximum effect of protection from extraneous sounds without damaging the structure of the room.

Main types of material and its characteristics

In the modern construction market you can choose different kinds materials that will help get rid of excess noise. They differ from each other in format, price category and content.

Let's look at some of the most well-known and proven materials for floor soundproofing shown in the photo in more detail.

Mineral glass wool

Synthetic fibers arranged in a chaotic manner give this material lightness and elasticity. Among its main positive characteristics, it should be noted high thermal insulation, sound insulation, fire-resistant properties, long term service, environmental safety, light weight and ease of installation.

Due to the fact that the material does not cause corrosive processes, it can be laid between metal pipes for insulation or sound insulation. You can install this material without special skills and knowledge, which makes it even more attractive.

Perhaps the only drawback of this material may be its thickness while saving every centimeter.

Foamed polyethylene

This material is usually used as a substrate for floor structures. In terms of its price category, it belongs to a fairly inexpensive materials. Installation is very simple.

Its disadvantages include its fragility, since over time it cakes, as a result of which its soundproofing abilities deteriorate.

It is also worth noting the lack of moisture resistance when wet - islands of mold can form on the surface, which will negatively affect the body, while being hidden from view.

Cork backing

This material is available in two versions - sheets and rolls. Pressed cork chips are especially known for their long service life.

The main differences include a high level of protection from vibration and noise, as well as resistance to rotting processes. When working with such material, you should strictly follow the attached recommendations for its installation.

Rubber-cork backing

Durable and fire-resistant combination material consisting of synthetic rubber and granulated cork. It is used as a soundproofing material for various floor coverings.

It is necessary to protect it from moisture and mold formation using vapor barrier materials.

Expanded polystyrene

Produced in sheets of varying thickness and density. Basic positive characteristics– this is strength, long service life. The material has almost zero moisture absorption, it can be used in rooms with high level humidity.

It has good sound insulation and thermal insulation qualities and is distinguished by its ease of installation.

Soundproofing the floor in the apartment

There are two main options for soundproofing floors: under screed and without screed.

Soundproofing the floor under the screed

The working surface is cleaned, and if there are defects, partial repairs are made. Afterwards, a layer of prepared soundproofing material is laid, followed by a layer of waterproofing.

The sheets of the top layer must be laid overlapping with projections on the walls of 5-10 cm. Carefully leveled upper layer filled with concrete screed. After it has dried, you can begin laying out the main floor covering.

It should be taken into account that the period completely dry concrete screed will be about 25-30 days.

Soundproofing floors without concrete screed

This option is carried out only if the floor is based on a high-quality concrete covering. On the previously prepared surface it is necessary to lay several layers of waterproofing and a layer of elastic gasket. Then line the panels with cellulose.

Subtleties of high-quality sound insulation

When organizing soundproofing work, several nuances should be noted in order to avoid unpleasant surprises:

When completely or partially laying communication systems underground, it is necessary to insulate them; for this, it is recommended to use elastic materials.

Skirting boards must be attached to only one of the surfaces - the wall or the floor - otherwise they can become noise conductors.

You must purchase building materials only from a trusted seller who can provide a quality certificate for the product. Saving on such materials can negatively affect the health of household members.

There are no special difficulties or big secrets in the process of laying soundproofing materials. Anyone who is familiar with basic construction skills can do this kind of floor soundproofing work with their own hands. A little patience and you can enjoy the long-awaited silence.
