I sleep badly and feel discomfort? Began to be annoyed for any reason? The best materials for noise insulation for the apartment will help to cope with your problems and create conditions for a full rest.

The causes of poor noise insulation serve:

• the inadequacy of the home facilities to standards standards;
• faults of fences. Emptiness and cracks reduce sound insulation;
• noise over measure in the apartments of the neighbors or from the outside street.

Every owner of the apartment or at home makes every effort to solve the inconvenience of life and protect against excessive noise. Soundproofing is required to create comfortable living conditions, both in their home and to avoid conflicts. Active children's games, home cinema, 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 noise view.

Distinguish:

• Air. Sounds transmitted from outside by air: lively traffic, deafening music, industrial enterprises.
• Shock. Drilling walls, drivening the nails during repair. However, specially intended isolation is necessary when conducting systematic work using a jackhammer.
• Structural. The road transfers the vibration of the walls of the apartment, transforming it into Decibel.

Attention! Noise from the motorway reaches 70 dB.
Noise insulating materials absorb sounds from the outside or prevent the spread from the apartment. It is required to find the appropriate material for the inside of the room.

What to pay attention to, choosing a noise absorbing material for the house?

When behavior of work on noise insulation should be considered:

• Dimensions of the room.

For small-sized premises - a children's room or a bedroom - a plasterboard sheet is suitable, which will not reduce the useful area. The spacious rooms are installed sound-absorbing multilayer structures in a special framework, occupying a lot of space. Stirol, mineral wool or kraft cardboard.

• Purpose of the room.

Materials suitable for the bedroom should not be used in the kitchen, which is characterized by elevated humidity and temperature fluctuations. Separate sustainable insulation materials.

• Invoice.

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

• Separate watches.

It is required not only to combine soundproofers and noise-insulating materials, but also take into account their quality properties. The purpose of the invoice is the interior decoration of the premises, so the substance harmful to health is excluded: bitumen and lead, mercury and formaldehyde, volatile resins, EPDM compounds and volatile resins.

• Sealing docks and cracks.

Designs requires integrity and monolith. Therefore, all extra holes and holes eliminate. Not sealed connection, uninsulated air pipes, risers and sockets lower noise insulation. Close up of joints with soft mastic or sealant.

• Qualified installation.

To achieve an effective result, competent minting is required. Qualified workers on noise insulation, repair and finishing will come to the rescue. It is important that sound insulation based on designer ideas corresponded to the interior inside the apartment or at home and did not prevent engineering communications.

Soundproofing partitions are performed exactly as well as the sound insulation of the wall, the only difference is that the sound insulation should be done on both sides. The basis of the partition - the metal frame is necessarily sampled by a damper ribbon. After that, the frame is filled with basalt or polyester wool and is trimmed. All joints are labeled with sound insulation sealant. The only difference from the noise insulation of the wall is the lack of vibrobodves. Instead, they use a special vibration-free SOUNDGUARD VIBRO WASHER for the mounting frame to overlaps.

Noise insulation of interroom partitions is not such a common task, such as the sound insulation of the walls, but if it is neglected, then in the future you can face that even a TV working in the next room will interfere with resting. In addition, the use of sound insulation materials is justified not only by creating acoustic comfort to the room. An important point is also the thickness of the erected partition. More and fewer people want to lose a large amount of useful area, making thick partitions from brick or aerated concrete and apply frame and drywall for these purposes. However, sound insulation in such structures is practically absent, so it is important to choose the correct materials that will delay the noise and will not add the thickness of the plasterboard partition.

In modern houses and offices, interior partitions are often used to distinguish between space. In order to save space, time and building materials, the frame walls from drywall, plywood and chipboard are most often erected. Sometimes, when building partitions, there is not enough attention to their noise insulation. If, for office and industrial premises, high-quality sound insulation is not so necessary, then for residential premises this question is extremely relevant.

Noise isolation of interior partitions of different types.

For comfortable accommodation in the apartment, attention should be paid to the reduction of sound permeability between adjacent rooms. Then music, noise of water or crying a child will not penetrate through interior partitions. Consider several sound insulation methods:

• "Dedovsky" method was tested by our parents. The essence is that it is worth hanging a carpet or put the wall on the wall, the noise from the next room immediately becomes quieter. The ability of soft fibers of the carpet to absorb sound and acoustic oscillations is also proved during scientific tests.
• Waste or sowing a wall with noiseless or sound insulation materials. This method is used if the interior partitions are made of durable materials - aerated concrete, bricks, clay-concrete blocks. As noise insulation, various substrates under wallpaper, rolled materials from PVC, PET or rubber, as well as a variety of membranes are used. The best option for such sound insulation is the heat - sound insulation mat SoundGuard carpet, which can be used for any surfaces.
• Noise insulation of plasterboard partitions is one of the most sought-after in the construction market. By themselves, frame structures made of metal profiles, tinted drywall are very thick. They do not just pass acoustic and vibration noise, and they can even strengthen them. Basalt wool, polystyrene foam, polyurethane foam and other noise-absorbing materials can be used for soundproofing such partitions.

Reliable noise insulation of partitions with their own hands.

It is usually imposed, much less operational requirements than to the bearing walls. Therefore, for their erection, thin-sheet materials are often used, first of all - drywall. However, the price for such convenience is relatively small strength, low heat and noise insulation.

If the first for inner walls is not so significant, then the second two points require an effective and operational decision on the construction stage. We will tell how designed and installedsoundproofing of plasterboard partitions, which materials and technologies are activated in this process.

Theoretical basis

Before assessing the insulating layers, it is necessary to understand the nature of the functions that they must perform, as well as in some major terminology.

Soundproofing is called a set of measures and technical solutions aimed at reducing the level of incoming noise.

The noises themselves are conditionally classified on three groups:

1. Impact - arise due to mechanical effects on the surface and initially distributed in a solid environment (blows, stuffs, screens, etc.)
2. Structural - formally are a type of drums, but due to their specifics are allocated to a separate group. There are due to the relative mixing of structural elements relative to each other, which is peculiar to, for example, frame houses. Constructive noise can be attributed, in particular, creaking parquet.
3. Acoustic - the most common group in which all sounds coming from external sources and entering the structure of walls and partitions from the air environment. An example of acoustic noise can be the voices of people and music.

If sound insulation is a general concept characterizing different activities, then noise absorption - a narrower, physical sphere indicating the degree of dispersion of sound waves in a solid medium.

In practice, both of these phenomena are inextricably associated with thermal insulation As a way to prevent heat loss as a result of heat exchange with an external environment.

Therefore, the modern building materials market includes many combined tools that provide comprehensive sound and thermal insulation of surfaces, although there are also "highly specialized" substances. You can learn more about them and other insulating materials from the next section.

What soundproofing material to choose?

Plasterboard partition with high-quality sound insulation is a complex comprehensive designin which it will not be possible to do with one or two insulating layers.

It will be necessary to correctly choose the sheets of plasterboard sheets, filling the partition, framework materials, and even fasteners.

So, the minimum set that will allow to extinguish up to 30% of noiseIncludes:

• Plasterboard GLC (HCLV) PC with a thickness of 9.5 or 12.5 mm - located in two or three layers with intervals filled with soundproofing material, with or without air layer.
• The main soundproofing layer is a sheet or rolled material located in the intervals of the Pie. The greatest distribution was obtained: Equata, basalt and mineral wool, felt or other substances.
• An additional soundproofing layer - is used less often and involves sizing the internal support surfaces of cork, a rubber transfect or foil substrate. For plasterboard partitions, the substrate is not too effective.
• The frame - is a supporting structure made, as a rule, from an aluminum profile. Serves for fixing drywall.

Such an approach to noise insulation of the partition will not bring due effect, even if you make the design of the multi-layer. This is explained by the vibration nature of sound waves, which are perfectly applied by the reporting surfaces of high hardness. In this case, the sheets, and the frame, and the fasteners of the frame are also served in their roles.

Reduce the effect of this chain will help the following measures:

1. application as an internal reference sheet not drywall, but OSB plates;
2. use of gaskets from microporous rubber between sheet materials and floors, ceiling, walls;
3. clamping frame profiles with soundproofing belt materials;
4. replacement of the aluminum profile on the timber bar from durable varieties of wood, for example, beech;
5. In the walls of special soundproofed dowels.

Properly performed complex of these actions will ensure the quenching of at least 80% of noise, which means that the voices, music on the average volume and the sound of the furniture of the partition will be almost not heard.

Montaja rules

The main soundproofing material is located between the supporting surfaces of the partition, which means that its layers may be several.

Fibrous materials that are supplied in rolls or sheets, depending on the specific density of the substance, were the greatest distribution. The form of manufacture places some specific installation requirements.


Soft rolled insulation is usually cut into areas equal to the height of the frames of the frame. One of the plots will have to trim and along. All sizes are performed with a reserve of 5-10%To ensure the tight fixation of the insulator in the interval.

In the case of installation of sheet noise insulation materials, their exact forming may be needed, which is relevant, first of all, with a small elasticity of the substance.

If the air layer will be located behind the layer of the insulator, admissible installation on frame platespreventing loss of sheets from the gaps.

Some nuances may occur with the simultaneous installation of heterogeneous noise and thermal insulation layers. In this case, the first, starting from the sound of the sound, have a thermal insulation layer. As a rule, its width is selected according to the width of the frame.

Thereafter put polyethylene film And begin to install, for which the most convenient use of leafy materials. They are placed in the frame of the other side of the partition or the free gap between them, for which the auxiliary fasteners can sometimes be needed.

Choosing a wall thickness

To unambiguously answer the question about the optimal thickness of the wall with sound insulation is impossible, because in each particular case a number of factors dependent from the specifics of the materials and place of installation.

Here are some main options With the range of medium thicknesses:

1. Without a separation layer, it consists of two layers of drywall (about 25 mm), a frame or two separate frames (about 50 or 80 mm) filled with insulator, and an air layer (about 25 mm), and a total of 90-150 mm.
2. With one inner separation layer, in addition to the described layers, takes into account the thickness of the middle plate (about 15 mm) and another layer. The total thickness of the partition is 160-200 mm.
3. With two separation layers (multi-layered design) or with additional insulation - they assume a margin according to 50 or 80 mm, which is consumed on the installation of another OSB plate with a layer or leaf insulation. The thickness range for the first case is 210-250 mm, for the second 240-280.

In addition, the thickness can be adjusted manually, depending on the architectural and design solutions of the premises.

Design and performing high-quality sound insulation of interior particles from drywall - a complex multi-level process, requiring responsibility, care, accuracy. But in the case of a competent approach to work, you can enjoy the complete silence and comfort of the rooms.

What sound insulation materials can be used for walls in the apartment Find out of the video:

We often face the need to divide a large room into smaller. At the same time, it is hardly paramount to newly formed rooms has acoustic polls. The separation occurs by erecting new capital or time wall structures - partitions. It is about them, or rather about how to enhance sound insulation of interroom partitions and will be discussed.

From a constructive point of view, interior partitions can be divided into two classes: single-layer and multi-layered.

Single-layer structures involve the use of any self-supporting relatively dense building material on a rigid binder (solution). These may be brick, plaster, ceramzite concrete and even reinforced concrete structures. Their sound insulation characteristics are determined, first of all, weighing and are improved by about 6 dB when it is doubled.

The porosity of the partition material also plays a role in ensuring its sound insulation qualities. However, as practice shows, the winnings due to the increase in the porosity of the material is leveled by losses due to the weight of the construction. Therefore, with rare exceptions, such partitions have sufficiently modest sound insulation.

Multilayer partitions, as follows from the name, consist of several (minimum three) alternating layers of hard (dense) and soft (lung) building materials. Dense materials (drywall, brick, metal) show sound insulation properties and work similarly to single-layer partitions: sound insulation is the higher, the greater the surface density of the material. Materials of the lung layer perform a sound-absorbing function, i.e. The structure of the material should be such that during passing through it sound oscillations the latter weakened by friction of air in the pores of the material.

It should be noted a low efficiency of use in sound insulation partitions of materials such as foam, polyurethane foam or cork. This is due to the fact that for good sound insulation materials, they have an insufficient density, and to calculate them to the class of sound-absorbing materials - too low absorption due to the lack of air purge.

The most common variant of the multi-layer partition is a three-layer frame-and-in-wing plasterboard partition. Its soundproofing characteristics depend on a larger number of factors than the single-layer partition. Ways to achieve the necessary sound insulation of the plasterboard partition only three:

• Increase the density of material of hard layers
• An increase in the distance between the extreme layers, i.e. An increase in the total thickness of the partition.
• Filling into the internal space of the septum with layers of a special sound absorber.

The most important thing is to implement the entire soundproofing potential of multilayer structures, the requirement of layer-by-layer sound through the thickness of the partition should be performed. Ideally, the sound wave must pass first only through the first rigid layer, then only through soft, then only through the second rigid layer, etc. In practice, the mandatory presence of a carrier frame leads to the fact that the sound oscillations of the first rigid layer are transmitted through a common frame (or common foundation) to the last rigid layer and re-energized them into the protected room. Thus, sound energy for rigid frame elements successfully passes specially prepared internal sound-absorbing layers traps, as a result of which the real soundproofing of multilayer structures is significantly lower than theoretically calculated values.

Select the correct sound insulation partition

When choosing one or another type of partition, the question inevitably arises: which partitions have the best sound insulation characteristics with the smallest thickness, mass and value? The traditional answer sounds like this:

Multilayer frame partitions as internal enclosing structures are preferable. With a much smaller mass (which is very important to reduce loads on overlapping and the foundation) and the thickness, they have almost the same, and sometimes greater, air noise isolation index (RW) than single-layer structures.

Soundproof frame partition on double frame 2x50mm	168 mm	65 dB.
Soundproof frame partition on double frame 2x100mm	268 mm	68 dB.

Note! For the isolation of interroom "household" noise, it is more preferable to use the structure of a light partition with a thickness of 108 mm, having a level of noise insulation, comparable in magnitude with sound insulation of a substantially more massive and thick wall with a thickness of 280 mm.

In our table, for comparing the sound insulation properties of partitions, we use the RW air noise insulation index. Despite some disadvantages, it is a very convenient parameter for a quick comparison of sound insulation of various partition structures among themselves and with the regulatory values \u200b\u200bof sound insulation of enclosing structures. In the territory of the Russian Federation since 2012, there is an updated edition of SNiP 23-03-2003 "Noise Protection", according to which the soundproofing of the ed-military wall in a residential building should be at least 52 dB (RW), and partitions between the adjacent rooms of the same apartment - not meee 43 dB.

As "sanitary standards", these numbers can still be consistent, but for truly comfortable living in the conditions of increased noise levels in modern housing they are clearly insufficient. Noise background in apartments, not even considering powerful sources, such as home theaters or Hi-end systems, over the past decades, we have grown in our country. Currently, in almost every house and each room has a TV, telephone, radio, and in the kitchen and bathrooms are washing or dishwasher, extractor, air conditioning, etc. The home computer also contributes to an increase in the overall noise background.

The existing experience suggests that for modern conditions, the air noise insulation index of the interroom partition should be at least RW \u003d 50 dB, and the ed-military wall is not less rw \u003d 60 dB. Only with such regulatory values \u200b\u200bof the enclosing structures can actually talk about acoustic comfort. However, even the wall with RW \u003d 60 dB will not fully solve the problem of sound insulation of the bedroom, if the neighbor's neighbor decided to see the new fighter in his home theater at night.

It is interesting that noise penetrating the streets through the open windows, causes much less irritation, the weaker sounds: music, screams, laughter, distinguished from the next apartment. Noise of vehicles, as well as the gross thunder, and behind the common buzzment is not worth an evil will of a particular person, while the neighbor behind the wall is preventing their TV - the person is known and clearly unpleasant ... Therefore, the domestic noise is much smaller intensity well the ear and the brain. This is due to the psychophysiological features of human hearing and psyche, and in the struggle for acoustic comfort, the dwellings with this also have to be considered.

Device of sound insulation partition

Below is the composition of the design of the soundproofing partition, which has the maximum acoustic properties with the minimum possible thickness on today. Such design easily provide an air noise insulation index from 56 to 62 dB.

First of all, these are light frame partitions on a metal frame. Interest represents the design on an acoustic profile with a thickness of 100 mm, sheathed from two sides by sheets of acoustic triplex and leaning gypsum Gyproc Aku-Line. It is time to tell about the advantages of the acoustic triplex Soundline DB and the rack metal profile of the vibrooflex-wave.

This is not only perfect for interior walls, but it can even be used as an ed-road partition for the most demanding customers. This design has a thickness of 158 mm. For those who need to do thinner - there is an option on a 50 mm profile, which also provides isolation is also quite good for interior partition - RW \u003d 56 dB with a thickness of 108 mm.

The overall effect of sound insulation of the partition also depends on the selection of the medium layer material. The main criterion for choosing such a material is the value of its dimensionless coefficient of the sound absorption α W, the values \u200b\u200bof which can vary from 0 to 1. The closer the value of α W to one, the higher the sound absorbing capacity of the material. To obtain the maximum effect, it is recommended to choose materials with α w at least 0.8. For example, a special sound-absorbing material - the acoustic mineral plate of class premium shumnet-bm is α w \u003d 0.95.

The thickness of the absorbing layer should be at least 50% of the internal space of the partition and be not thinner than 100 mm (it is natural that only one layer of the sound absorber with a thickness of 50 mm can be applied with a thickness of 50-75 mm).

To achieve the stated sound insulation indicators of partitions, the accuracy of the installation of such structures is of principle. The framework elements associated with the side walls and overlaps should be isolated with elastic pads of vibrastek-M, and the joints after installation are sealed with a sealant vibrating to eliminate indirect transmission of sound. Detailed schemes of data of these partitions with a list of necessary items are given in the album of engineering solutions Acoustic groups, ASP-401-0915 cipher.

Video instruction on the installation of soundproofing partition:

The purpose of interior partitions is to divide the inner space of the house into several separate rooms. Build them from a variety of materials, both heavy and lungs. From the type of material used and the structural features of the partition, the noise level in the house will depend on much.

The problem of sound insulation will be perfectly cope with massive partitions, and to achieve the required level of "silence" when installing light designs, a sound-absorbing material is laid between the trimbs.

The noise form different sources: the household comes from the working TV and human voices, the low-frequency is published by working engineering equipment, for example, ventilation. A special air noise isolation index has been developed, its minimum value for interior partitions 45 dB.

If you compare a heavy partition and a light framework, then with the same index, the massive will better reflect the low-frequency sounds. Acoustics - the science is complex, and only a specialist can achieve ideal noise absorption. But it should be understood that any hole in the partition, for example, slits around the perimeter of the door box, significantly worsen sound insulation.

What kind of designs are able to hold its level in acceptable limits? High recurring and sound-absorbing properties have volumetric partitions from porous materials: aerated concrete, ceramics. With a thickness of the partition 10 cm, the noise absorption index will be 40 dB, at 15 cm - 50 dB. If additional measures are required - you can leave the air layer between the two rows of masonry or separate the plasterboard wall.

Noise absorption will significantly increase the double layer of facing material.

An excellent soundproof effect can be achieved using multilayer partitions: the sound will be reflected in them with outer rigid plasterboard walls, and to be absorbed by the inner soft layer of basalt fiber-based plates. The more the rigidity of the external cladding, the better sound insulation, so you can do it in two layers. The advantage of a narrow multilayer septum in front of the monolithic - in saving the useful space.

Types of sound insulation materials

Some materials are capable of reflecting the sound, others absorb. The first group includes solid materials: concrete, metal, brick, plasterboard. In the second - materials with a fibrous structure or in the form of grains and cells. They are made on the basis of mineral or glass gamble in the form of plates and rolls.

The best result gives the use of membrane sound-absorbing materials, but their distribution limits the high price. It is very convenient to work with it, since a small thickness allows you to glue it.

Characteristics of sound insulation materials for partitions

Stiffness materials	Materials	Sound— absorption	Characteristic
Soft	Materials based on mineral wool, felt, fiberglass	0,7 – 0,95	fire safety, low weight; elasticity; nonhygroscopic; high vapor permeability.
Solid	Materials based on suspended or granulated mineral wool; Materials include porous aggregates: pumice, vermiculite, perlite.	0,5	fire resistance; high porosity; does not enter into chemical reactions; high heat insulation; frost resistance.
Semi-rigid	Mineral wool; fiberglass; Polyurene Foolder	0,5 – 0,75	low thermal conductivity coefficient; low weight; high adhesive strength; durability; high ecology.

To lay sound insulation materials, a framework will be required. If you use an aluminum profile, then it will also pass outside sounds. Therefore, under the frame put a special tape gasket from polyurethane. Profiles are attached to the ceiling, floor and walls of dowels with a pitch of 40 cm. Sound insulation organization for different partitions

Next, one or two layers of plasterboard are attached to one of the sides. Cut the size of sound insulation mats and insert them into an empty partition space. If necessary - place inside the communication and finishing works. All places where the frame is attached to hard structures, isolate with elastic gaskets.

The wooden frame is built from the bars, laying between the racks of the plate of sound-absorbing material and are trimmed with plywood, clapboard or GKL. The covering of two layers or a double-row frame with air layer significantly increase the sound insulation index.

As for the brick partition, it makes sense in the thickness of the floor brick (125 mm) to conduct sound insulation activities. It is suitable for mounted facing of a metal frame, which is covered with plasterboard from the side of the room in 1-2 layers. The gap between the plasterboard and the wall laid any of the sound-absorbing materials.

When eliminating small holes and cracks in partitions, the best result will give acrylic and silicone sealants, and not a mounting foam: it has low sound insulation properties. If you have these simple noise elimination operations, then the house will be much quieter and comfortable.
