The most sound-absorbing material. Soundproof materials. ISOPLAAT - tiled soundproofing material

All noise can be classified into three categories: airborne, impact and structural. The most common type, of course, is airborne noise - these are the sounds of passing vehicles, the buzzing of equipment and the sounds made by animals and people.

The sound insulation index - Rw - will tell about the ability of a particular material to protect against noise.

Impact noise, as the name implies, occurs when shocks occur, for example, when hammering nails or moving furniture. Finally, structural noise is the sounds of nature penetrating through the structural elements of the house.
The key characteristics of a soundproofing material are the actual sound insulation and sound absorption. It must reflect or absorb sound, preventing it from entering the room.

From the point of view of acoustic engineers, there are no soundproofing materials in nature - only special designs in which structure is extremely important. Often, builders use multilayer systems in which sheets of dense drywall alternate with layers of porous materials, such as mineral wool. But, unfortunately, they reduce living space and are quite expensive.

The secret of effective sound insulation is the combination of a special design and material.

Overview of popular soundproofing materials

Modern technologies allow the use of simpler and more profitable materials that provide isolation from external and internal noise. So, ZIPS sandwich panels have proven themselves well on the market. They are a combination of dense gypsum fiber and soft glass wool layers. Their thickness varies from 40 to 130 mm, and Rw is 10 dB.

A thinner material is ISOPLAAT heat and sound insulation boards. Their thickness does not exceed 25 mm, while their sound insulation index is twice as high as that of ZIPS - 23 dB. In addition, ISOPLAAT is made from environmentally friendly fibers of coniferous trees. The plates are mounted with glue and "breathe" well.

The thinnest panels are EcoZvukoIzol and Kraft - 12 mm and 13 mm, respectively. The former are made of a seven-layer cardboard profile with the addition of quartz sand, the latter are made of fibreboard. Both those and others are easily attached with ordinary glue. The sound insulation index of both is approximately equal to 23 dB.

Finally, it is worth warning about the most common misconceptions. There is an opinion that materials such as cork, PPE, polyurethane foam do a good job of soundproofing and at the same time, thanks to their small thickness, help to save square meters. In fact, this is not entirely true - they only absorb impact noise, but do not at all isolate from the air.

Overview of soundproofing materials

A wide range of materials is used for soundproofing rooms, and each type is designed to be used taking into account the characteristics of the room, the type and source of extraneous sounds.

You will need

- sound-reflecting materials
- sound-absorbing materials
- combined soundproofing
- damper soundproofing materials

Instruction

The main obstacle to getting extraneous sounds into the dwelling is an array of walls, partitions and ceilings. The lack of density and thickness of fences is a very urgent problem for the communal residential sector. The solution to the problem is the use of a wide variety of soundproofing materials designed to increase the comfort of housing and protect owners from external stimuli. However, you need to know that certain types of materials are designed for use in specific situations.

The most common materials used for soundproofing rooms are rolled layers made of dense and elastic substances: rubber, bitumen, cork or rubber. The main purpose of such noise insulators is to reflect powerful sound vibrations propagating at a low frequency - the so-called impact noise. Examples of such are the sounds of a working drill or hammer drill, household appliances. The main feature of these sound sources is the propagation of vibration through the material of walls and ceilings. Sound-reflecting materials repel this vibration due to the mechanical properties of elasticity, preventing it from penetrating the insulation layer.

There is another source of extraneous annoying sounds - airborne noise. These include human speech or animal sounds, music, or car alarms. To eliminate such noise, sound-absorbing materials are used, which have a low density and a special structure: fibrous or cellular. Fibers are the basis of glass or mineral wool, while the cellular structure is characteristic of polyurethane, polyethylene foam or expanded polystyrene. Such materials effectively scatter sound vibrations with high frequency and low amplitude, due to which the room

Peace and quiet - every resident of an apartment building or a house located near a noisy highway dreams of this. Fortunately, soundproofing materials, combined with their proper use, will help get rid of all kinds of noise. This will be discussed - how to properly apply soundproofing.

Often, by noise, many people mean only one type of sound - air. These are the sounds that come to us from the outside: passing cars, screams of children in the yard, barking dogs, a construction site nearby. However, there is also an impact type of noise (hammering nails into the wall, the notorious drilling in the neighborhood, rearranging furniture) and structural noise - in this case, the sounds are transmitted directly through the building structure, the elements of which are joined rigidly and without the use of soundproofing pads.

A person feels comfortable with sound vibrations within the limit of 25 decibels., although sanitary standards somewhat overestimate this rate - up to 30 dB at night and up to 40 dB during the day. Of course, each person has his own standards of perception - someone calmly endures all 60 dB, but more decibels can make you seriously nervous.

For this, soundproofing was invented - its task is to reflect noise, not to allow them to pass through walls and other obstacles into your environment. Good for those who have thick walls - by themselves they perfectly reflect sound vibrations. However, this hardly applies to most panel houses and new buildings. In addition to sound insulation, there is also sound absorption - the ability of materials to absorb sound waves. Most granular, fibrous or cellular materials just have this ability.

Among such materials, soft, semi-rigid and hard are distinguished. Soft sound absorbers are made of fiberglass or mineral wool, as well as felt and ordinary wool. These include pumice and vermiculite - the so-called porous aggregates. Semi-rigid materials include plates made of the same fiberglass or mineral wool, as well as materials with a cellular structure, for example, polyurethane foam. By the way, their sound absorption coefficient is slightly higher than that of soft ones, but their specific gravity is greater.

Airborne noise is the easiest to deal with - porous and fibrous materials that can be mounted both outside and inside the building are saved from it. In addition, they have another property - thermal insulation, so their use is doubly beneficial. Impact noise can also be "plugged" with closed-cell materials by laying them around the perimeter of walls and ceilings. But structural noise is a more significant problem, because the materials must be laid at the construction stage.

For noise insulation of structural noise, it is recommended to use soundproof panels as the main element in the construction of structures. The panels are produced under different brands, such as FonStar, Sonoplat, Tycho, SoundGuard and others. The choice is yours. We can only recommend Ticho Group products in terms of price-quality ratio. .

Vibroacoustic sealant is used when filling joints in the construction of floating floors, cladding and frame partitions. The material provides a high degree of vibration isolation, does not cause metal corrosion, has good adhesion to most building materials such as brick, concrete, ceramics, wood. The cured sealant is odorless, but when working with it, ensure good ventilation of the premises and avoid contact with skin and eyes.

Silica fiber gaskets are a lesser known material used for soundproofing rooms with high fire safety requirements. This material is safe for humans and non-flammable. It is important to note that the presence of one type of sound insulation does not guarantee peace and quiet in your house or apartment - you need to skillfully arrange these materials in order to achieve a really significant effect.

For protective materials of this kind, such an indicator as the sound insulation index, measured in dB, is characteristic. The second indicator is the degree of sound absorption, which is measured from 0 to 1. The closer this degree is to one, the better the material. As already mentioned, thick walls themselves protect the comfort of our home from extraneous sounds. However, to increase the massiveness of walls and ceilings is a task too difficult for the layman, and inefficient.

The most acceptable way of soundproofing in this case is to create a multilayer structure from hard, cellular and soft materials, which can be done with your own hands from popular building materials.

In most cases, drywall acts as a rigid material - its thickness is optimal for interior work, when it is important to preserve as much living space as possible. Drywall acts as a soundproofing material, while a layer of soft material takes on sound absorption. As already mentioned, these include glass wool, mineral wool, polyurethane foam and other cellular formations. For effective sound absorption, the layer of material in a multilayer structure must be at least 50 mm and make up at least half of the entire structure.

The task of soundproofing floors, as well as in the house, is performed by an acoustic ceiling - also a multilayer structure that reduces the energy of sound vibrations and absorbs them. This requires the formation of an air space between the floor and the ceiling area - it is filled with pressed mineral or fiberglass boards.

After all, there is a cheaper polyethylene foam! Quite often, laminate flooring manufacturers offer it along with their products. Polyethylene foam is used both for soundproofing floor coverings and floating floors, and for sealing joints. It is resistant to almost all solvents, it is in good contact with cement and other finishing materials. However, when wetting the space filled with polyethylene foam, good conditions are created for mold colonies. In addition, prolonged loads lead to a loss of material thickness (up to ¾ of the original value), which in turn leads to a loss of soundproofing properties.

The composite material, consisting of two layers of polyethylene film and expanded polystyrene beads, is an improved version of the use of polyethylene. The top layer provides protection against moisture penetration into the structure. The lower film lets air and steam into the space between the films, but from there they are removed through the seams. Such ventilation prevents the accumulation of moisture and mold. The composite material does not deform and serves for a long time - from 20 years. When laying, the use of adhesives is not required.

The cork-rubber backing consists of cork and rubber granules. This material perfectly dampens the vibration of household appliances and other appliances. It is effective to lay such a substrate both under elastic and hard floor coverings: linoleum, parquet, laminate, tile. However, the cork-rubber coating needs additional protection from moisture, since it serves as a medium for the emergence and development of mold.

To ensure a good level of comfort, both for life and work, it is very important to create a pleasant sound environment. To solve this problem, soundproof materials are used. They are widely represented in the construction market. You can choose a solution according to any parameters: place of application, cost, scope of work, etc. Moreover, in a number of materials, sound and noise insulation is combined with thermal insulation or waterproofing, which is very convenient.

Soundproof materials

Installation of soundproofing walls can be done by yourself, although it is better to turn to teams specializing in this. Also, given that soundproofing work requires rather dirty processes, you should try to install soundproofing even at the stage of preparing the room for finishing.

There are several types of noise that can be grouped into two groups:

Airborne noise. These are sounds that are carried through the air: screams, conversation, laughter, music. Such noise comes from neighbors through small gaps and cracks in walls and ceilings, as well as through open windows;
impact noise. These are sounds that are carried along hard floors and walls. Otherwise, shock noises are also called vibrations. Such sounds are especially irritating and unpleasant: perforator drilling; subwoofer; slamming doors; stomp; jumping.

To measure airborne or impact sound, special equipment is required. There are various models of such devices: from professional expensive ones to household ones with quite affordable prices up to 2000 rubles. Regardless of the cost, the principle of operation of noise measuring instruments is the same. Converting vibrations of the trapping membrane into electric current. The greater the amplitude of oscillations, the more amperes are generated. The final data is displayed on the scoreboard.

Noise level tester

According to SNiPs, the acceptable noise level in residential buildings during the daytime (from 7:00 to 23:00) is 40 decibels (dB), which is comparable in volume to a normal conversation.

The upper noise threshold for this time should not exceed 55 dB, which is comparable to the volume level of a typewriter or light clapping of the palm on the table. At night in residential buildings, the upper sound threshold is set at 40 dB, but the recommended noise level is 20-25 dB (whisper volume).

Often these requirements are not achievable. And often not because of someone's malicious intent, but because of the features of the house: thin walls, thin partitions, through holes for electrical boxes and sockets, and much more. If the vibration insulation in the house does not meet the desired, then the best solution would be to install special soundproof structures or materials.

Materials for sound insulation must be selected based on how high-quality sound insulation of walls is required. Preference, ceteris paribus, is usually given to those materials whose sound insulation index is higher. The sound insulation coefficient, sound insulation index or impact sound reduction index is a qualitative indicator that reflects how many dB the impact noise transmitted through walls and ceilings will be reduced.

Specialized types of sound insulation

There are many types of soundproofing materials. Some of them are used exclusively in construction and decoration, and some are universal.

A separate section highlights automotive noise insulation. Materials that are used on car bodies can also be used in construction.

So, for example, automotive vibration-damping mastic is perfect if you need to reduce the volume of a tin roof and barn walls made of metal corrugated sheet. The mastic is applied with a brush or, if the consistency allows, with a spray gun. It dries quickly and dampens noise and vibration quite well.

Another good soundproofing solution in an apartment, which is borrowed from the automotive world, is vibration-damping materials such as Vibroplast or the like. Sheet and roll materials are made on a bitumen basis, akin to Shumaizol or Soundizol. An important difference is that Vibroplast is self-adhesive. It is very easy to mount it - you just need to peel off the protective layer and press the sheet against the surface to be insulated. Convenient solution for vibration isolation of small areas. For example, this way you can improve or a balcony door.

To create a practically soundproof house, it will not be enough to use only one of the materials listed. On each element of the structure, some of their own decisions will be appropriate and effective. It is best if a combination of several materials is used: for vibration absorption, sound insulation and sound absorption.

Noise is not such a harmless phenomenon as it might seem: it is no coincidence that its level and time, acceptable for noisy work and entertainment, regulated by law.

If you suffer from riotous neighbors, the noise of running equipment, or screams coming from the sports ground, don't try to get used to: it can cause health problems(from hearing loss and nervous disorders to hormonal disruptions and cardiovascular diseases).

In cases where it is impossible to neutralize the noise source, the only reasonable solution would be the acoustic insulation of your own apartment.

Overview of modern materials

The first thing to know about acoustic insulation is that sound absorption and sound insulation are different concepts.

Soundproofing- this is the establishment of obstacles in the path of a sound wave that will not allow sound to penetrate into the room or, conversely, to spread outward. Sound absorption occurs due to the conversion of sound energy into heat and a decrease in the intensity of the reflected wave.

Naturally, different materials are required for these purposes: soundproof materials must have sufficient large mass and density, and sound-absorbing - to have soft, porous texture.

So, we list the main sound-absorbing materials:

Fiberglass or mineral wool boards(better than basalt) are quite effective, but have a noticeable thickness (from 3 cm). They are embedded in a special frame inside the casing of plasterboard or gypsum fiber sheets.
Expanded polyurethane panels(acoustic foam rubber, "sound-absorbing pyramids") are simply attached to the glue, and under them it is not even necessary to level the surface. The thickness of such a panel is from 3.5 to 10 cm; the height of each pyramid is from 2 to 7 cm.
Liquid soundproofing- only the name, in fact, sound absorption occurs. It must be applied in a thick layer (at least 3 cm), without particularly leveling: you still have to cover it with drywall or a decorative panel.
Cork sheets or roll cork- the coating is decorative, but with a thickness of 0.8-1 cm, you can use it for sound insulation. Sound absorption will be more effective if the diameter of the pressed chips is no more than 3 mm (be sure to pay attention to this, because there are chips up to 6 mm in diameter).

For soundproofing, products from the following list are usually used:

Wall cladding with plasterboard or gypsum boards with fastening to a wall on a relative. Between the wall and the sheathing, a gap of at least 4 cm wide must be provided for filling with noise-absorbing materials (see above).
Soundproof panel systems(ZIPS or sandwich panels) - industrial version of the previous version; their thickness varies from 5.5 to 13.5 cm. Finished sandwich panels are mounted directly on the wall in a frameless way.
Decorative soundproof panels- thin (1.2-1.5 cm) layered material from a cardboard frame and loose mineral filler (eg quartz sand). To prevent sand from spilling out when cutting panels, it is necessary to seal their sections with special adhesive tape.
Acoustic boards made of soft fibreboard- ply construction, including waterproofing, polystyrene foam and reinforcing mesh. Depending on the thickness of the filler, the plate can turn out to be thin (from 1 cm) or wide (about 10 cm).
wood fiber panels(usually coniferous trees) is also relatively thin (from 1.2 to 2.5 cm) facing material with soundproofing properties.
Thin high density membranes in essence, the material is homogeneous, but for the convenience of attaching to the wall, they sometimes have a coating.

How to choose the right insulation material?

If you do not take into account the financial component and subjective preferences for the color of the panel sheathing, then There are only two main criteria:

Who will carry out the work: professionals or the residents themselves?
What is more important: to reduce the decibel level as much as possible or to save the useful area of the apartment?

If the installation is planned to be done by hand, then it is better to choose sandwich panels (ZIPS), which are assembled in a frameless way, or any coating that is glued to the wall with the entire surface.

More complex complex insulating structures are best left to install by professionals.

The answer to the second question allows you to choose between:

wall cladding with multilayer panels or drywall (with subsequent filling with soft noise-absorbing material);
thin soundproof coatings.

Read also about choosing the best material for facing the facade of the house.

Thin soundproofing materials

Objectively, thin soundproofing is not self-sufficient: even manufacturers in the description of the material often indicate that it is intended for use as part of "puff" panels.

Nevertheless, many people prefer to do everything possible for sound insulation even in the case when, for some reason, “sandwich” designs are not applicable.

Here is a list of the most common materials and their approximate thickness:

lead foil in a “case” made of polyurethane foam - 0.7 cm;
polymer-bitumen membrane coated with polypropylene - 0.4 cm;
mineral membranes - 0.25-0.37 cm;
polyethylene insulation for wallpaper - 0.5 cm (more details in the next sections).

Among thin single-layer materials, those that have high mass and density and as high a critical frequency as possible (preferably outside the range that can be heard by the human ear) - that is, definitely not polyethylene.

Not everyone knows that the soundproofing capabilities of a material depend on the frequency of the "hostile" sound. So, the critical frequency is the lowest frequency, after which the soundproofing characteristics of the material are reduced.

From familiar materials highest critical frequency has lead, one level lower - steel, concrete, brick, rubber. If you choose according to this criterion, then the best option is a lead membrane. But since lead is not the healthiest element periodic table, it is worth taking a closer look at the polymer-bitumen membrane: this artificial material has a critical frequency of lead, but does not contain harmful impurities.

The most popular mineral membranes - aragonite (texaund) and barite (noise block, loaded vinyl) - contain polymers as a binder, which give the material plasticity and elasticity. The small thickness of the membranes allows them to be used in several layers to improve the effect, alternating with noise absorption.

With a little stretch thin sound insulation can be attributed to the previously discussed:

acoustic boards (minimum thickness 1 cm);
decorative panels made of wood fibers (from 1.2 cm);
rolled cork coating (from 0.8 cm).

The main ways to isolate noise with your own hands

Plastic windows can cope with the noise coming from the street, but the main thing here is not to overdo it: you should not order a two-, three-chamber double-glazed window, since more glass not only does not improve, but in some cases may degrade soundproofing. It is better to install a single-chamber package (of two glasses) with as much distance as possible between them.

It is much more difficult to level the noise coming from indoor sources (in our case, an apartment building). Fortunately, the preparatory stage of soundproofing your apartment able to fulfill any who has ever dealt with renovations.

It is better to start by sealing the joints between the plates and sealing other cracks and holes. If the gaps are large, blow them out with foam or, at worst, tightly rammed with rags, if small - just gently putty over.

The next important point is to get rid of through sockets (for this you will have to slightly redraw the electrical wiring) and strengthen all the rest in the socket.

Now it's the turn of the plaster (of course, high quality, elastic, with good adhesion). It turns out that a thick layer of plaster plus putty already gives a good level of sound insulation: in a standard situation, when the neighbors have no repairs, no holidays and no fights, you can sleep or work in peace.

Soundproofing the walls in the apartment: video instruction.

If “standard” situations are rather an exception to the rule, then additional acoustic insulation is indispensable. For DIY installation fit:

soundproof sandwich panels (ZIPS);
decorative panels with loose filler;
panels made of wood fibers or compressed cork chips;
thin high-density insulating coatings;
liquid soundproofing;
polyethylene backing for wallpaper.

All these materials do not require special installation skills: with their help, everyone can equip a soundproof room!

For wall insulation in spacious rooms, preference should be given to combined multilayer structures: their soundproofing characteristics are significantly higher than that of homogeneous materials.

If you are a professional in the field of repair and construction work, it will not be difficult for you to sheathe the walls with mineral-filled or fiberglass-filled plasterboard inside the sheathing: this option is a classic of acoustic insulation, but will cost less good finished panels.

How to soundproof walls under wallpaper?

So, the walls are prepared for finishing putty. If you decide to make light sound insulation with polyethylene foam, then it is not necessary to putty to the ideal, the material itself perfectly hides small irregularities.

The polyethylene foam substrate for wallpaper is usually already pasted over with paper on both sides and rolled into rolls, so it is simply cut into pieces of the desired length and glued to the plaster (without overlap!) with heavy wallpaper glue.

Be sure to take care in advance that during work and when the material dries the temperature in the room was above 10◦C.

When the substrate dries, you can glue any wallpaper: both ready-made and for painting (material has water repellent properties, so the water emulsion will not damage it).

Acoustic ceiling insulation

The purpose of soundproofing a ceiling is to get rid of not only air (spreading through the air), but also structural (spreading through the floor slabs) noise.

The last type of noise is also called vibration or shock: this includes sounds that occur when furniture is dragged, heavy objects fall, walking on heels on parquet, etc.

Important: no matter which method of soundproofing is chosen, the first step is to foam or putty the gaps between the plates.

Whatever the original height of the room, it is better to sacrifice centimeters: the best solution for impact sound insulation is the installation of a suspended plasterboard or stretch ceiling.

Moreover, the gap between the ceiling and the newly formed ceiling must be filled with good noise-absorbing material (see photo) (Never use styrofoam!).

Pay attention also to the fact that the fasteners (and the substrates under them) are also soundproof.

Both stretch and suspended ceilings have many enthusiastic supporters among professional builders, so it's up to you to decide. An additional advantage in favor of the tension will be that its coating itself is already is a decorative element, while the drywall construction needs to be puttied, wallpapered or painted.

If the height of the room is so low that you cannot even think of reducing it, it is worth trying decorative ecological soundproofing panels. (1.2-1.5 cm thick) or an ultra-thin aragonite soundproofing membrane.

Important: soundproofing one ceiling (without walls and floor) will not help to completely remove even noise from neighbors from above, since sound can also propagate through wall partitions.

The review of materials for acoustic insulation carried out here is, of course, not complete, but it can be a starting point for your search.

Sleep badly and feel uncomfortable? Have you become annoyed for any reason? The best soundproofing materials for an apartment will help you cope with your problems and create the conditions for a good rest.

The reasons for poor sound insulation are:

inadequacy of the construction of the house to the norms-standards;
fencing failures. Voids and gaps reduce sound insulation;
noise beyond measure in the apartments of neighbors or from the street from the outside.

Every owner of an apartment or house makes every effort to solve the inconvenience of everyday life and protect himself from unnecessary noise. Soundproofing is required to create comfortable living conditions, both in your home and to avoid conflicts. Active games for children, home theater, musical instruments - a partial list of objects and related activities for scandals.

To determine the choice of raw materials, it is necessary to establish the type of noise.

Distinguish:

Air. Sounds transmitted from the outside by air: busy traffic, deafening music, industrial enterprises.
Shock. Drilling walls, driving nails during repairs. However, specially designed insulation is necessary when carrying out systematic work using a jackhammer.
Structural. The road transmits vibration to the walls of the apartment, converting it into decibels.

Attention! Noise from the motorway reaches 70 dB.
Soundproofing materials absorb sounds from the outside or prevent the spread from the apartment. It is required to find a suitable material for the interior of the room.

What to look for when choosing sound-absorbing material for your home?

When performing soundproofing work, the following should be taken into account:

Room dimensions.

For small rooms - a children's room or a bedroom - a drywall sheet is suitable, which will not reduce the usable area. In spacious rooms, sound-absorbing multi-layer structures are installed in a special frame, which occupy a lot of space. Styrene, mineral wool or kraft cardboard.

The purpose of the room.

Materials suitable for the bedroom should not be used in the kitchen, which is characterized by high humidity and temperature fluctuations. Select stable insulating materials.

Invoice.

Its use in monolithic concrete houses differs from frame buildings. The quality of sound insulators depends on the price.

Invoice quote.

It is required not only to correctly combine sound insulators and soundproofing materials, but also to take into account their qualitative properties. The purpose of the texture is interior decoration, therefore substances harmful to health are excluded from the composition: bitumen and lead, mercury and formaldehydes, volatile resins, EPDM compounds and volatile resins.

Sealing joints and cracks.

The structures require integrity and solidity. Therefore, eliminate all unnecessary holes and holes. Unsealed connection, uninsulated air pipes, risers and sockets reduce sound insulation. Sealing joints with soft mastic or sealant.

Qualified installation.

To achieve an effective result, competent mounting is required. Qualified workers in soundproofing, repair and decoration will come to the rescue. It is important that soundproofing based on design ideas matches the interior inside the apartment or house and does not interfere with engineering communications.

Soundproofing for ceilings

Often it is not enough to stick the roll insulator. Cork or tile wallpaper will help solve simple problems. To soundproof the ceiling, you will have to give up the height of the apartment. The most effective technique is the construction of a ceiling structure.
Distinguish:

stretch ceiling made of film or fabric, which is installed on pre-fortified brackets;
false plasterboard ceiling. Mineral wool or other soundproofing material is placed in a metal frame attached to the ceiling;
suspended ceiling. When installing the frame, soundproof fillers are used: cork, polyurethane foam blocks, coconut fibers, basalt wool cork. Closed with panels.

Practical video tips on installing ceiling soundproofing with your own hands:

Wall soundproofing

Before work, they inspect the wall and close up cracks and cracks. The fastest and most convenient way is to rub with cement. Pull out electrical outlets and check for voids. If necessary, lay with mineral wool, seal the hole with putty or cement before putting the outlet in place.

Soundproofing material and installation methods are selected according to the price, efficiency and quality of sound insulators, as well as the footage of the “eaten up” usable space.

A variety of textures are used for decorative soundproofing of walls. The construction services market provides a wide range of products. Are especially popular with consumers:

drywall;
soundproof panels;
roll material.

Video instruction for working with spare parts panels for soundproofing walls:

Drywall installation

Assemble the frame. If the walls are thin, fix the profile on a rubber lining. Mineral wool or other material as a noise absorber is embedded in the prepared crate. The structure is covered with plasterboard sheets. Shpatlyuyut, finishing.

Assembling the soundproofing panel

With a perfectly even coating, the panel is installed immediately on the wall. Fastening thanks to the notch-protrusion lock or using construction adhesive. The problem of leveling the wall covering is solved in two ways: by assembling the frame, as is the case with mounting drywall or putty.

The panel installation is quite simple. No finishing required as surface coating is available. A variety of materials and colors: paper tapestries, fabric, wood or stone lamination.

Pasting of roll noise insulators

Save money and time. Convenient to use. Glue is used for dense vinyl or non-woven wallpaper. The work is not very difficult, the result is good for an inexpensive material. Rolled sound insulators cope with 60% of noise.

Sound insulation for partitions

As a rule, sheathing is used in two or three layers. Installation is carried out in various variations: drywall, plywood, glass-magnesite or gypsum-fiber sheet. The construction of 2 layers of plasterboard sheets with a sheet of gypsum fiber has not only massiveness, but also positive resonant properties. Vertical fastening of sheets with screws at a distance of 25 cm, so that the layers are connected with a shift. The joining of the plates is sealed with putty or silicone sealant.

More about soundproofing partitions - in the video:

Frameless coating

ZIPS panels, unlike a metal frame, are attached directly to the wall. They present a sandwich consisting of dense plasterboard sheets and a plastic sound absorber made of staple glass wool.

For adhesion of the plates, a tongue-and-groove docking is used, for strengthening - a vibration-proof assembly. Plus: the minimum "eaten" usable space. Cons: expensive.
