Noise isolation of walls in apartment modern materials for which today can be found in building shops, it becomes more actual. This is simply explained - the fencing in multi-storey standard houses is not able to fully protect the dwelling from external street noise and from sounds coming from neighboring apartments.
Scientists-physicians of have noticed for a long time that the presence of constant noise extremely negatively influences a person's psyche, not allowing him to get a full relaxation and rest. It is the therefore, , not withstanding the constant sound pressure, many residents of cities, especially those who live in panel houses, begin active searches for a suitable soundproof material that will meet all the requirements of its application in the condition of apartments.
Almost all modern acoustic materials are manufactured on the same basic bases as traditional ones. However, they have undergone a significant improvement due to the recent production technologies.
To date, a very large number of new soundproof materials are produced and the characteristics of all on the scale of one article can not be covered simply. Therefore, attention will be focused on the most effective, which find application in the conditions of an apartment.

This soundproof material made of basalt fibers is considered a mineral sound absorbing premium panelclass. One side of the mat is laminated with an fiberglass layer, which helps maintain the integrity of the plate and keep internal basalt fibers in one position to prevent small particles from entering the room. This is especially important in cases where the sound-absorbing material is covered with perforated acoustic panels.
The plates " Shumanet BM " are produced in accordance with the requirements of SNiP 23 - 03-2003 "Noise protection".They have the following technical and operational characteristics:
Parameters of the material | Parameters |
---|---|
Standard plate size( mm) | 1000 × 500 or 1000 × 600 |
Plate thickness( mm) | 50 |
Density of the material( kg / m³) | 45 |
Number of plates in the package | 4 |
Area of plates in the packageone package( m²) | 2,0 or 2,4 |
Weight of one package( kg) | 4,2 ÷ 5,5 |
Package volume( m³) | 0,1 ÷ 0,12 |
Sound absorption coefficient( average) | 0.95 |
Flammability( GOST 30244-94) | NG( non-flammable) |
Water absorption at partial immersion in water for 24 hours, as% of total | No more than 1 ÷ 3% |
Acoustic tests to determine the sound absorption coefficient were performed by in the measurement laboratory of the Moscow Institute of Building Physics at the Russian Academy of Architecture and Construction .
Having a low degree of desiccation , this soundproof material can be used not only in rooms with normal humidity, but also, for example, in the bathroom. In addition, it is excellent for noise insulation of tension and suspended ceilings, and, of course, walls and multi-layered partitions made in the form of a sandwich of plasterboard, plywood, fiberboard and other sheet materials.
Soundproofing of walls using " Shumanet BM "
The soundproofing plates are installed in the same way as all mineral wool types. However, it is necessary to take into account the fact that the material will be used primarily as sound absorber , and only then it is considered as an additional insulation.
The work is carried out in the following order:
- On the prepared and primed wall, the marking is made for fixing the elements of the crate. Since the width of the mat is 500 mm, and they should stand between the bars, the distance between the guides should be 450 ÷ 480 mm. If mats are purchased in 600 mm width, then, respectively, the distance between the bars should be 550 ÷ 580 mm.
- Next, the elements of the are fastened, but at the same time, to avoid weakening the basic qualities of the soundproof material, experienced masters advise to perform a number of simple recommendations:
- For , the is best used with wooden beams, not metal profiles, as metalis a good conductor of sound, can resonate, and wood has the ability to muffle sound waves.
- In addition, in order not to create bridges for sound transmission, it is recommended between the wall and bars of the crate to make gaskets from a thin soundproof material, for example, felt or stripes of basalt wool with a thickness of 8 ÷ 10 mm.
- If the is still for the of the crate, a metal profile is selected, then it is better to move it away from the wall with a soundproof gasket of 12-15 mm.
anti-vibration pads. - In the case that the area of the soundproofed room is large enough, and there is the possibility to remove crate for sound absorbing material and casing 100 mm from the wall,special parts - suspension .They are screwed to the wall through wooden gaskets, and in them bars are already fixed.
Another option - the use of special hangers, which are designed specifically for noise-absorbing structures. Structurally, such an article already has a special damper layer, which effectively dampens vibrations without transferring them to the frame guides.
If guide rails are fixed in the above manner, then the soundproofing mats are mounted in two layers. The first one is installed behind the elements of the crate , flush against the wall, and the second - between the rails.
- In the end, , after the installation of the panels Shumanet BM has been completed, the walls should look like this:
Next, soundproof vapor-permeable diffuse membrane. Then they proceed to the installation of gypsum boards or plywood sheets, which, in turn, will become the basis for finishing works. However, it is quite possible to replace this layering by fastening directly to on boards wooden decorative lining.
It should be noted that all sound - and heat insulation materials made in mats or rolls are mounted on the walls on the same principle.

« Teksaund » - new direction in technology soundproofing
« Teksaund » still not as popular as rock wool or polystyrene foam, as it is relativelynew soundproofing. The most important advantage of " texaunda " in front of other soundproof materials is that it practically does not " steal " useful area premises, since it has a small thickness.
This soundproofing device is used for all surfaces of the room - , it is fixed to the ceiling and walls, and is also laid on the floor.
It should be noted that some masters use " texound " in combination with thermal insulation materials, and this bundle only increases the efficiency of its application. But, unfortunately , the rooms in the apartments most often do not have extra space, which can be given to the "powerful" multi-layer sound - and heat insulation design. In this regard, and was developed material that can protect the room from excessive noise and not reduce the room in this size.
To achieve the desired effect and to protect the room from external sounds, it is necessary to cover with soundproofing material all the surfaces of the room, otherwise it will be impossible to achieve the desired result.
The " texound " was developed in Spain by the specialists of the famous company TECHSA , and launched its mass industrial production in the same place .It is in this country that the largest mineral deposit of aragonite is located, which is the main source raw material.
If to be more precisely , then the basic component is calcium carbonate( CaCO³).This compound is very rich in aragonite. In addition, calcium carbonate is the main constituent of m m of leg lime rocks, including chalk, marble and others.
As harmless polymer compounds, harmless polymer compounds are used, and as a result, high-density membranes are obtained, but at the same time - is very flexible and elastic, with viscous-elastic qualities, which is extremely important for noise insulation of complex building structures.
The soundproofing of rooms with this material is very effective even in the case when we use paintings with a very small thickness." Texdown " is able to absorb and scatter even high-intensity sound waves that come not only from the outside, but also are created indoors, for example, with very loud music.
" Texdown " is produced in webs and is marketed in polyethylene packed rolls. It has the following technical and operational characteristics:

Tensile strain( %) | 300 |
construction materials mineral aragonite, plasticizers, polyolefins, spunbond |
In addition, the material has the following advantages:
- " Texdown " is resistant to temperature changes. Its elasticity does not decrease at all even at negative temperatures before - 20 ° C .
- The - has a pronounced flexibility and ductility, and by this the Texdown in the is somewhat similar to the rubber.
- The material is resistant to moisture and will never become a zone of mold or fungus spread, as it has antiseptic properties.
- Operating time « texound » - is not limited.
- " Texdown " is perfectly combined with other materials, and can be applied in a complex system.
" Texdown " is subdivided in its thickness, size and shape, it can have additional layers that improve its characteristics. The main brands are represented in the table:

Installation « teksaunda »
For the installation of this material is suitable for almost any base - concrete, drywall, plastic, wood, metal, and others. The main thing is that the surface is well prepared - is aligned, cleaned of old coatings, primed and dried.
If there is a quality on the wall applied plaster layer, then it must be primed, and then the installation can be carried out directly on it.
Work can be done in two ways. In the first of them only soundproof material is used, and in the second one - it is used in combination with a heat insulator.
The first option - without additional insulation
- Adhesive is applied to the prepared surface. For the installation of texound , a special mounting adhesive is used, which is sold by in ready-to-use liquid form, in cans. After lubricating, should wait for for 15-20 minutes, until the glue is seized.
- Next, the soundproofing material itself is mounted on the glued wall, which must be measured by and cut off in advance, and pre-glued with glue.
- If the self-adhesive material is purchased, then the installation will be much easier, because to Lei is not needed, and you just need to remove the protective film and attach the material to the wall.
- Further, the sheet " texound " should be pressed as close as possible to the surface, and then walk along it with a platen. This must be done to achieve the best its his clutch to the wall surface throughout the area, without leaving air bubbles .
- Cloths " Texaunda " must be laid overlapping , approximately by 50 mm. The sheets are glued together tightly. This procedure ss pr is carried out with the help of the glue "liquid nails" or by heating the material with hot air or a gas burner - adjacent sheets are welded together. If the installation between the canvas will leave at least some small gaps, the efficiency of sound insulation will be significantly reduced.
- If the installation Texound is held on the ceiling, it is glued in small sheets, because the material is heavy , and the solid sheet from of the wall to of the wall will simply not be retained.
- After gluing the canvas, if necessary, it is additionally fixed on the wall with the - fasteners "fungi", the ones that are most often used for mounting expanded polystyrene or mineral wool.
The second option - using thermal insulation
Complex installation is carried out in the event that the wall needs not only soundproof , but also insulated. If there is such a task, then the works are carried out in the following way:
- On the primed wall along the edges is fixed the frame of the crate .
- The next step on the entire wall in one version immediately adheres to " Texdown ", and in the other - pre-stacked heat insulation material. However, the first method shows more efficiency for acoustic insulation.
- In case the thermal insulation is adhered to the wall, texound is fixed first with "fungi", and then it is pressed additionally with the slats of metal hangers.
- In order to achieve the required place for the installation of a thermal insulation material, the metal profile of the frame is fixed in the suspension at a distance from the wall of 40-50 mm. In this case, it is necessary to set each of the profiles according to the building level, otherwise the skin of the frame will not be level.
- The next step is mounting insulation. The most environmentally friendly of suitable insulating materials that can be installed independently, is mineral wool on a basalt basis. If financial means are allowed, then you can use the above-mentioned " Shumanet BM", which is not only sound-absorbing , but good thermal insulation material.
- It fits tightly between the pillars and is pressed to " Texoundu ", attached on the wall.
- After the installation of the insulation, the wall should look like this:
- Heater is suitable to tighten the by a vapor-permeable diffuse membrane.
- The next stage of is the wall plasterboard plasterboard. In some cases, for plying uses plywood or OSB sheets.
- Fastening of sheets to racks of a crate is carried out by self-cutters, which caps are put in material for 1,5 ÷ 2 mm.
- drywall sheets. The joints and holes are then sealed from the self-tapping screws .
- Next, the surface is primed and shpaklyuetsya completely, and then you can decorate the walls with decorative material.
Drywall is the most convenient material for aligning the of the
walls. The wall, which received the soundproof and thermal insulation, must be prepared for further work - to achieve an even surface that will become the basis for the finishing materials.

Existing mounting schemes " texound "
The masters apply various schemes for mounting this soundproofing. Depending on the convenience of the work, the area of the room and the necessary efficiency of wall insulation from external noise, you can choose any of them. The only drawback of these designs is their thickness, which even at best will be no less than 50 mm.
The first version of
This design will have a thickness of 50 mm.
- Begin its mount from the fact that the prepared metal profiles from their side against the wall are pasted with a self-adhesive tape " Texound S BAND 50".This must be done in order to avoid the transmission of sound and vibrations from the wall along the metal frame into the room.
- Next, the frame elements are fixed to the wall with dowels, and between them are mounted heat-insulating, sound-absorbing mats.
- Then, on the sheets of gypsum board, on their inner side, the soundproofing material is glued. In the this case, the is suitable " Tesund 70".
- After this, . gypsum board is fixed on the frame racks, and its seams are sealed with with .
The second version of
The thickness of the construction with this option will be 60 mm.
- In this case first a thin heat insulator is fixed to the wall. You can use a foil heater, setting it with a reflective surface toward the room. The heater must cover the joints of the wall with the floor and ceiling, that is, the on them should be inserted on the 150 ÷ 200 mm.
- On top of it is manufactured metal frame assembly, which as well as in the first design, is attached to the wall.
- Further, heat insulation mats are placed in the frame, which are covered with plasterboard with Texaud 70 pasted onto it.
It should be noted that the heat-insulating material attached to the wall can be replaced with on " Texdown FT 75", which has an additional layer of felt.
The third version of
The thickness of the third variant of the design is 70 ÷ 80 mm, since it consists of more layers of .
- The first layer to the wall is installed heat insulation material.
- The second layer comes sound-absorbing membrane " Texound ".
- on top is mounted crate .
- Then the heat insulation mats are installed.
- The last layer on the structure is fixed sandwich panels, consisting of two sheets of plasterboard, between which is laid " Texound ".
Buying soundproof material of such type , it is recommended to provide the consultant of the selling company with the characteristics of the material from which the house was built. The sales consultant will help to make the right choice by determining the thickness and the best form of the issue " Texdown ".

Use as noise insulation foam foam mats
The most effective affordable material for soundproofing walls in the apartment can be called acoustic foam. Due to its porous structure, this material perfectly absorbs and dispels sound vibrations.
