Soundproofing walls in an apartment modern materials for which today can be found in construction stores, is becoming increasingly relevant. This can be explained simply - fences in multi-storey buildings standard houses are not able to completely protect the home from external street noise and from sounds coming from neighboring apartments.

Medical scientists It has long been noted that the presence of constant noise has an extremely negative effect on the human psyche, preventing him from getting complete relaxation and rest. That is why, unable to withstand the constant sound pressure, many city residents, especially those who live in panel houses, begin an active search for a suitable soundproofing material that will meet all the requirements for its use in apartments.

Almost all modern acoustic materials are made on the same basic principles as traditional ones. However, they have undergone significant improvement thanks to the developments in Lately production technologies.

Today there are very many a large number of new soundproofing materials, and it is simply impossible to cover the characteristics of all in one article. Therefore, attention will be focused on the most effective ones, which are used specifically in apartment conditions.

Thin sound insulation MaxForteSoundPRO

When the area of ​​an apartment or room does not limit the choice of materials, and you can install sound insulation of any thickness, this is convenient. But what if you can’t afford to waste precious centimeters of living space?

In this case, the innovative thin soundproofing material MaxForte SoundPRO is suitable for you. It has a thickness of only 12 mm, while its characteristics can compete with sound insulation with a thickness of 5 and even 10 cm! MaxForte SoundPRO — newest material, created specifically for soundproofing residential and industrial premises.

Specialists from the Research Institute of Building Physics and the Department of Acoustics, Faculty of Physics, Moscow State University, took part in the development of the material. When manufacturing MaxForte SoundPRO, we took into account all important points for the material to work effectively: the optimal density was selected (if the density is low, the sound will pass through, if the density is too high, along the “skeleton”), the length of the fibers, and their thickness. The sound-absorbing layer is calibrated and uniform over the entire area. The material is completely non-flammable. The composition does not contain harmful phenol-formaldehyde resins or any adhesives. Therefore, in addition to excellent noise insulation properties, MaxForte SoundPRO is safe for health.

MaxForte SoundPRO provides an increase in noise insulation from both airborne noise (loud TV, crying child, screaming neighbors) and impact noise (noise from stomping, grinding furniture, falling objects). It can be used to soundproof ceilings, walls and floors, which will give a significant increase of up to 64 dB!

Installation of thin sound insulation is very simple, and not only professionals can handle it, but also anyone who has ever held a hammer drill and a screwdriver in their hand.

MaxForte SoundPRO is mounted on the wall using ordinary plastic mushroom dowels, which can be purchased at any hardware store. It is hung on the wall using the “joint-to-joint” technology, after which it is covered with a layer of gypsum fiber board (gypsum fiber sheet). All sheet seams must be sealed with a special vibroacoustic non-hardening sealant. Afterwards, the sound insulation is sewn up with a layer of gypsum plasterboard (plasterboard sheet). The seams of the gypsum fiber board and gypsum board sheets should be staggered, that is, not coincide.

You can see the installation of thin sound insulation MaxForte SoundPRO in the video.

Thin wall soundproofing panelsSoundGuard EcoZvukoIzol

SoundGuard EcoZvukoIzol panels are a unique material for soundproofing walls and ceilings, which allows you to achieve silence in the apartment and not lose useful space.

SoundGuard EcoZvukoIzol panels are made of durable multi-layer cardboard profiles based on the honeycomb principle, which are filled with thermally treated mineral quartz sand. The quartz filler used is very fine, exactly the same as an hourglass. It is this filler that makes it possible to achieve an impressive weight of the panel - more than 18 kg per m2, and according to the laws of sound insulation, the heavier the material, the worse it transmits sound (cotton wool transmits sound very well, but for example a brick wall or steel door much worse). In addition to its weight, quartz sand, due to its fine fraction, perfectly dampens and absorbs almost all frequencies of sound - from airborne to shock.

How to install panelsSoundGuard EcoZvukoIzol?

Installation of the panels is very simple and almost anyone can handle it. are attached to the wall using SoundGuard DAP acoustic anchors, which are driven into pre-drilled holes through the panel in the wall. After this, all seams and joints are coated with sealant and the entire wall is covered with plasterboard.

Mineral sound-absorbing material "Shumanet-BM"

This soundproofing material made from basalt fibers, is considered a premium mineral sound-absorbing board. One side of the mat is laminated with a layer of fiberglass, which helps maintain the integrity of the slab and hold the internal basalt fibers in one position to prevent their small particles from entering the room. This is especially important in cases where the sound-absorbing material will be covered with perforated acoustic panels.

Packaging of soundproofing boards “Shumanet”

Plates " Schumanet BM" are manufactured in accordance with the requirements of SNiP 23 — 03-2003 “Noise protection”. They have the following technical and operational characteristics:

	Indicators
Standard slab size (mm)	1000×500 or 1000×600
Slab thickness (mm)	50
Material density (kg/m³)	45
Number of slabs per package (pcs.)	4
Area of ​​slabs in one package (m²)	2.0 or 2.4
Weight of one package (kg)	4.2÷5.5
Packaging volume (m³)	0.1 ÷ 0.12
Sound absorption coefficient (average)	0.95
Flammability (GOST 30244-94)	NG (non-flammable)
Water absorption when partially immersed in water for 24 hours, % of total volume	No more than 1÷3%

Acoustic tests to determine the sound absorption coefficient were carried out in the measurement laboratory of the Moscow Research Institute of Building Physics at Russian Academy architecture and building sciences.

The basis of “Shumanet” is basalt fibers

Having a low degree moisture absorption, this soundproofing material can be used not only in rooms with normal humidity, but also, for example, in the bathroom. In addition, it is excellent for soundproofing suspended and suspended ceilings, and, of course, walls and multi-layer partitions made in the form of a sandwich of plasterboard, plywood, fiberboard and other sheet materials.

Soundproofing walls using Schumanet BM

Installation of the slabs of this sound insulator follows the same principle as all types of mineral wool. However, one must take into account the fact that the material will be used primarily as sound absorber, and only then is considered as additional insulation.

The work is carried out in the following sequence:

• On the prepared surface, markings are made to secure the sheathing elements. Since the width of the mats is 500 mm, and they must stand apart between the bars, the distance between the guides should be 450 ÷ 480 mm. If mats 600 mm wide are purchased, then, accordingly, the distance between the bars should be 550 ÷ 580 mm.
• Next, the sheathing elements themselves are fixed, but at the same time, in order not to weaken the basic qualities of the soundproofing material, experienced craftsmen advise following a number of simple recommendations:

— For lathing, it is best to use wooden beams rather than metal profiles, since metal is good guide sound, can resonate, and wood tends to dampen sound waves.

— Additionally, in order not to create bridges for the passage of sound, it is recommended to make gaskets from thin sound-proofing material, for example, felt or strips, between the wall and the sheathing bars basalt wool 8 ÷ 10 mm thick.

— If, after all, a metal profile is chosen for the sheathing, then it is better to move it away from the wall with a soundproofing pad by 12 ÷ 15 mm.

- In the case that the area soundproof the room is large enough, and it is possible to move the sheathing for sound-absorbing material and cladding 100 mm from the wall, then special ones can be used to fasten the bars details - hangers. They are screwed to the wall through wooden spacers, and the bars are already fixed in them.

Another option is the use of special suspensions, which are designed specifically for noise-absorbing structures. Structurally, such a product already has a special damper layer that effectively dampens vibrations without transferring them to the frame guides.

Special suspension used for soundproofing work

If guide bars secured in the manner indicated above, then the soundproofing mats are mounted in two layers. The first of them is installed behind the sheathing elements, close to the wall, and the second is installed between the guides.

Double-layer placement of “Shumanet” panels

• Ultimately, upon completion of installation of the Schumanet BM panels, the walls should look like this:

Next, on top of the mats soundproofing material is fixed vapor permeable diffuse membrane. Then they proceed to the installation of plasterboard or plywood sheets, which, in turn, will become the basis for the execution finishing works. However, it is quite possible to replace this multi-layering by fastening it directly to the guide lathing of wooden decorative lining.

Next, the wall is covered with a diffuse membrane and covered with plasterboard or plywood

It should be noted that all sound and heat insulating materials made in mats or rolls are mounted on walls according to the same principle.

"Texound" - a new direction in sound insulation technology

"Texound" is not yet as popular as mineral wool or expanded polystyrene, since it is a relatively new sound insulator. The most important advantage of Texound over others soundproofing materials is that it practically does not “steal” the usable area of ​​the room, since it is small in thickness.

The main advantage of Texound is the highest efficiency of sound insulation with a small thickness of the material itself

This sound insulator is used for all surfaces of the room - it is fixed to the ceiling and walls, and also laid on the floor.

It should be noted that some masters use Texound in combination with thermal insulation materials, and such a combination only increases the effectiveness of its use. But, unfortunately, the rooms in apartments most often do not have extra space that can be given over to a “powerful” multi-layer sound and heat insulating structure. In this regard, a material was developed that is able to protect rooms from excess noise without reducing the room in size.

To achieve the desired effect and protect the room from outside sounds, it is necessary to cover all surfaces of the room with soundproofing material, otherwise it will be impossible to achieve the desired result.

Texaund was developed in Spain by specialists from the well-known company TEXSA, and its mass industrial production began there. It is in this country that the largest deposit of the mineral aragonite, which is the main raw material, is located.

To be more precise, the basic component is calcium carbonate (CaCO³). Aragonite is very rich in this compound. In addition, calcium carbonate is the main component of many calcareous rocks, including chalk, marble and others.

Harmless polymer compounds are used as binding components, resulting in membranes high density, but at the same time very flexible and elastic, with pronounced visco-elastic qualities, which is extremely important for sound insulation of complex building structures.

Soundproofing rooms with this material is very effective even if canvases of very small thickness are used. “Texound” is capable of absorbing and dispersing even high-intensity sound waves that come not only from the outside, but are also created indoors, for example, with very loud music.

Texaunda canvas covered with protective film

“Texound” is produced in sheets (membranes) and goes on sale in rolls packaged in polyethylene. It has the following technical and operational characteristics:

Name of material parameters	Indicators
Material density (kg/m³)	1900
Average specific gravity canvas (kg/m²)	6.9
Area covered by one package (m²)	6.1
Weight of one package (kg)	42
Sound insulation coefficient Rw (average)	28
Flammability (GOST 30244-94)	G2
Elongation at break (%)	300
Manufacturing materials	mineral aragonite, plasticizers, polyolefins, spunbond

In addition, the material has the following advantages:

• "Texaund" is resistant to temperature changes. Its elasticity does not decrease at all even with negative temperatures up to - 20 °C .
• The material has pronounced flexibility and ductility, and in this way “Texound” is somewhat reminiscent of rubber.

"Texound" with its plasticity resembles dense rubber

• The material is resistant to moisture and will never become an area for mold or mildew to spread, as it has antiseptic properties.
• The operating time of the Texound is not limited.
• Texound combines well with other materials and can be used in a complex system.

“Texound” is divided according to its thickness, size and release form, and may have additional layers that improve its characteristics. The main brands are presented in the table:

Name	Sound insulator release form	Linear parameters of the material, mm

Installation of "texound"

Almost any base is suitable for installation of this material - concrete, plasterboard, plastic, wood, metal and others. The main thing is that the surface is well prepared - leveled, cleaned of old coatings, primed and dried.

If there is a high-quality layer of plaster on the wall, then it must be primed, and then installation can be carried out directly on it.

The work can be carried out in two ways. In the first of them, only soundproofing material is used, and in the second, it is used in combination with a heat insulator.

The first option - without additional insulation

• Glue is applied to the prepared surface. To install the Texaund, a special mounting adhesive is used, which is sold in ready-to-use liquid form in canisters. After coating, you must wait 15-20 minutes until the glue sets.

Marking and cutting of Texound canvases

• Next, the soundproofing material itself is mounted on the glued wall, which must be measured and cut in advance, and also pre-coated with glue.

Special glue is applied both to the surface of the wall and to the Texound canvas itself.

• If you purchase self-adhesive material, then installation will be much easier, since adhesive will not be needed, and you will just need to remove protective film and attach the material to the wall.
• Next, the texaund sheet needs to be pressed as tightly as possible to the surface, and then additionally walked over it with a roller. This must be done to achieve better adhesion to the wall surface over the entire area, without leaving air bubbles.

Welding Texound joints using a gas torch

• Texound canvases must be overlapped by approximately 50 mm. The sheets are glued together hermetically. This process is carried out using liquid nails glue or by heating the material with hot air or gas burner– adjacent sheets are welded. If during installation even small gaps are left between the panels, the effectiveness of sound insulation will be significantly reduced.

Doorway completely finished with Texound

• If Texound is installed on the ceiling, then it is glued in small sheets, since the material is quite heavy, and it will simply be impossible to hold a single sheet from wall to wall.
• After gluing the canvas, if necessary, it is additionally fixed to the wall with fastenings - “fungi”, the same ones that are most often used for installing polystyrene foam or mineral wool.

The second option is using thermal insulation

Complex installation is carried out if the wall needs not only soundproof, but also insulate. If there is such a task, then the work is carried out as follows:

• The sheathing frame is attached to the primed wall along the edges.

Texound frame around the perimeter of the wall

• The next step is to immediately glue Texound to the entire wall in one version, and pre-lay it in the other heat insulating material. However, the first method shows higher efficiency specifically for sound insulation.
• If thermal insulation is adjacent to the wall, the “texaund” is first secured with “fungi”, and then additionally pressed with strips of metal hangers.

Fixing Texound panels with mushroom dowels

• To achieve the required space for installing the insulating material, the metal profile of the frame is fixed into hangers at a distance of 40÷50 mm from the wall. In this case, it is necessary to set each of the profiles according to construction level, otherwise the frame skin will not be smooth.

Installation metal frame on top of soundproofing sheets

• The next stage is the installation of insulation. The most environmentally friendly suitable insulation materials, which can be installed independently, is considered to be basalt-based mineral wool. If financial allow facilities, then you can use the above-described “Shumanet BM”, which is not only sound-absorbing, but a good thermal insulation material.

• It fits tightly between the sheathing posts and is pressed against the Texound mounted on the wall.
• Upon completion of the installation of insulation, the wall should look like this:

• It is advisable to tighten the insulation vapor permeable diffuse membrane.
• The next stage is . In some cases Plywood or OSB sheets are used for cladding.
• The sheets are fastened to the sheathing posts using self-tapping screws, the heads of which are recessed into the sheathing material by 1.5 ÷ 2 mm.

• Then the joints and holes from the screw heads are sealed with putty.
• Next, the surface is primed and puttied completely, and after that you can decorate the walls with decorative material.

Drywall is the most convenient material for leveling walls

The wall that received soundproofing and insulating protection, it is necessary to prepare for further work - to achieve a flat surface, which will become the basis for finishing materials. As well as in special publications on our portal.

Existing texound installation schemes

Masters apply various schemes installation of this sound insulator. Depending on the convenience of performing the work, the area of ​​the room and the required efficiency of insulating the walls from external noise, you can choose any of them. The only disadvantage of these structures is their thickness, which even in the most best case scenario will be at least 50 mm.

First option

This design will have a thickness of 50 mm.

• They begin to install it by covering the prepared metal profiles on the side of their contact with the wall with self-adhesive tape “Texound S BAND 50”. This must be done in order to avoid the transmission of sound and vibrations from the wall through the metal frame into the room.
• Next, the frame elements are fixed to the wall with dowels, and heat-insulating, sound-absorbing mats are mounted between them.
• Then, soundproofing material is glued to the plasterboard sheets on the inside. In this case, Texound 70 is suitable.
• After that. drywall is fixed to the frame posts, and its seams are sealed with putty.

Second option

The thickness of the structure with this option will be 60 mm.

• In this case, first a thin heat insulator is attached to the wall. You can use foil insulation, installing it with the reflective surface towards the room. The insulation should cover the joints of the wall with the floor and ceiling, that is, extend to them by 150÷200 mm.
• On top of it is produced installation of a metal frame, which just like in the first design option, it is attached to the wall.
• Next, insulation mats are laid into the frame, which are covered with plasterboard with Texound 70 glued to it.

It should be noted here that thermal insulation material, attached to the wall, can be replaced with Texound FT 75, which has an additional layer of felt.

Third option

The thickness of the third design option is 70 ÷ 80 mm, since it consists of more layers.

• The first layer of thermal insulation material is installed on the wall.
• The second layer is the Texound sound-absorbing membrane.
• A sheathing is mounted on top of it.
• Then the insulation mats are installed.
• The last layer on the structure is sandwich panels, consisting of two sheets of plasterboard, between which Texound is laid.

When purchasing soundproofing material of this type, it is recommended to provide the consultant of the selling company with the characteristics of the material from which the house is built. The sales consultant will help you make the right choice by determining the thickness and better shape release of Texound.

Using foam mats as sound insulation

The most effective affordable material for soundproofing walls in an apartment can be called acoustic foam rubber. Due to its porous structure, this material perfectly absorbs and dissipates sound vibrations.

Acoustic foam rubber is capable of neutralizing two types of noise - sound and vibration waves, that is, it muffles sound and dissipates low frequencies arising from vibrations of surfaces, for example, knocking or “bass” of music.

The material is quite durable and can be installed either as an independent soundproofing material or in combination with drywall. Foam mats are available in a wide range of sizes and can be textured or have a flat surface.

Foam rubber is made by pressing polyurethane foam, after which it is cut into standard blocks measuring 1000 × 2000 mm. The thickness of the mats varies from 10 to 120 mm. Material domestic production It is produced in two or three colors, while imported versions have a more diverse range of colors, including 10÷12 colors.

Types of material relief

The types of relief patterns of acoustic foam rubber can be different. Both the total thickness of the material and its sound-absorbing properties.

The main types of reliefs used for the purpose of soundproofing rooms are presented in the tables below:

Material relief height (mm)	25	50	70	100
"Wedge"
	For moderate sound insulation of walls and ceilings.	Effective for absorbing standing sound waves and echoes in medium to small rooms.	For effective soundproofing of rooms of any size.	To absorb low frequencies, most often used in large halls.
"Pyramid"
	For moderate protection of walls against penetration of high and medium frequencies.	Protection against standing waves in small spaces. In combination with traps for low frequencies, they can completely soundproof a room.	Suitable for rooms of any size and used in conjunction with additional elements soundproofing such as sound traps.	Same characteristics as wedge material type

There are other, less commonly used elements made from acoustic foam.

Name of relief type	Characteristics
"Peak"	This mat relief is less popular and has unusual drawing. Its lack of demand is explained by lower soundproofing qualities than those of the materials mentioned above.
"Bass Trap"	Low-frequency waves are more difficult to dampen because they are longer. For this purpose, bass traps are installed in each corner of the room, which are designed for rooms of any size.
"Treble and Mid Frequency Traps"	These elements are installed in the halls big size. They are designed to capture mid and high frequencies, and create a low frequency diffusion effect. They are installed in a vertical position, but if the blocks are cut in half and installed in the corners, they will become low frequency traps.
"Corner block"	Corner blocks are produced in the form of a triangular beam. They are installed in the corners of the room and at the junctions of two surfaces, and also serve to dissipate low frequencies.
Decorative ceiling tiles	They are produced with or without a relief pattern. They are designed to change the relief and shape of the ceiling, thereby achieving an additional soundproofing effect.
Insulating wedges	Used to reduce vibrations from studio equipment and used as a substrate for it.

Until recently, acoustic foam rubber was rarely used in apartments, since the material tends to accumulate dust. But in recent years, more and more residents panel houses foam rubber is chosen to reduce the sound conductivity of walls. Thanks to its high sound-absorbing and dissipating properties, this material can make a room almost completely soundproof, provided it is installed not only on walls, but also on the surface of the ceiling and floor.

It is very important to note that acoustic foam rubber does not lose any of its soundproofing qualities when it is covered with plasterboard. The main condition in creating such a structure is that the foam mats themselves must be glued directly to the base of the wall, without any lining.

Soundproofing walls with acoustic foam

Installing foam rubber on walls is not too complicated, so you can easily do it yourself. In this case, it is worth considering the most acceptable method of sound insulation for apartment conditions, but it should immediately be noted that the area of ​​the room will be slightly reduced.

Installation work is carried out in the following sequence:

• To make the foam stick easily, it is best to prime the wall surface and dry it well.
• Next, the mats need to be fixed to the wall. They must fit tightly to its surface, otherwise the sound insulation effect will be partially lost.

• You can glue foam mats using wide double-sided mounting tape, “liquid nails” or heated silicone.
• When all the walls are covered with foam mats, you can proceed to the installation of frame sheathing made of metal profiles or wooden beams. The frame guides are mounted at a distance of 50÷60 mm from the wall.
• The racks are mounted in the recesses of the relief pattern directly to the wall. Holes for fastenings are drilled directly through the foam.
• After fixing the frame of the sheathing, sheets of plasterboard, plywood, PVC panels or other finishing materials are fixed to the guides. This will not in any way reduce the sound absorption efficiency of the foam layer, since it will be the first to receive all sound waves coming from outside, absorb them and dissipate them.
• In the same way, the foam rubber is mounted on the lathing. The lathing is installed directly on it, and then one of the types of suspended ceilings is fixed.
• On the floor, logs are laid on top of acoustic foam rubber, on which a plank or plywood floor is laid. Further, if desired, laminate, linoleum, carpeting or other decorative covering can be laid on the plywood.

It should be noted that the installation of acoustic mats does not require serious preparatory work. repair work, and if the decision is made to leave the foam panels open, then their installation will generally take no more than one day.

Exposed material will require frequent cleaning with powerful vacuum cleaner to prevent large amounts of dust from accumulating inside this porous material. If one of the panels comes away from the wall for some reason, it can be quickly and without special preparation glued into place.

In addition to the soundproofing materials considered, there are others in the assortment of construction stores. But today, acoustic foam rubber, Texaund membranes, Schumanet slabs and similar sound insulators can be called the most effective and safest for installation in an apartment.

By sound insulation of airborne noise (and there is also structural noise and vibration) we correctly understand the property of a structure (not a material) not to allow sound to pass through itself. Obviously, brick itself does not have sound insulation, but Brick wall The materials themselves can be divided into sound-absorbing and sound-reflecting, depending on what predominates in them. At the same time, both are often used in soundproofing structures. In general, the principle of alternating sound-reflecting and sound-absorbing layers to increase sound insulation can be called one of the main ones in acoustics.

An example of an absorbent material is fiberglass board or polyurethane foam (foam rubber) with open pores; sound reflecting materials include concrete, glass, drywall, etc.

Therefore, the term “soundproofing materials” or “soundproofing materials” is correctly understood as materials for improving (increasing) the sound insulation of an existing barrier by installing an additional structure. For walls, this can be a gypsum plasterboard partition on a frame base with filling; for ceilings, it can also be a frame structure in the form of a suspended ceiling.

On the one hand, we see that to solve soundproofing problems, conventional building materials are always used (gypsum plasterboard, metal profile, fasteners, etc.), but in order to really get the maximum effect, it is important to understand the following. Firstly, in addition to conventional materials, it is necessary to additionally use special “sound-proofing materials” - vibration-isolating pads to reduce the transmission of structural noise, sound-proofing materials inside the frame, and much more. Secondly, it is important to know the technology of the design itself, the correct arrangement of materials relative to each other. It would be appropriate to give the following analogy: soundproofing materials are medicines for a disease, but only a professional doctor knows how, using them in combination, to cure the disease without harming the patient. In our case, the doctor is an acoustic engineer who, having made the correct diagnosis, will suggest a “course of treatment” for the “patient.”

So, now we can move on to a brief overview of “soundproofing materials”.

"ZIPS" - Sound Insulating Panel System, consisting of sandwich panels (GVL and glass/mineral fiber), fastening elements, vibration-insulating cushioning materials (Vibrosil\Vibrostek) and special installation technology. A characteristic feature of the system is its “vibration isolation” and “frameless” structure, which makes it possible to obtain higher values ​​of additional sound insulation with the same thickness in comparison with frame structures.

"Shumanet-BM" is a sound-absorbing (unfinished) mineral wool slab on a basalt base. In terms of physical and technical characteristics, it is comparable to basalt slabs with a synthetic binder. Distinctive feature- guaranteed acoustic properties, constant density of 45 kg/m3 and a lot of experimentally confirmed data on the high sound insulation properties of structures using Schumanet-BM.

"Shumanet-100" is a rolled soundproofing gasket material. It consists of a special elastic multilayer fiberglass material, impregnated on one side with a layer of bitumen covered with polyethylene film. Unlike foam cushioning materials, also used to insulate impact noise, “Shumnaet-100” is distinguished by two important features- high acoustic efficiency and durability combined with acoustic stability, namely:

"Shumanet-100" with a thickness of 3 mm has an index of additional impact noise insulation of at least 23 dB, and with a thickness of 4 mm - at least 27 dB, respectively. The 8 mm thick extruded polyethylene foam pad has an additional impact noise insulation index of only 19 dB.

For foamed materials, after 5-10 years, due to the partial disintegration of molecules, the acoustic and strength properties are significantly reduced, and the amount of residual deformation increases. Fiberglass materials, on the contrary, do not age; their guaranteed service life is up to 25 years. In addition, additional static and dynamic loads (the weight of the floor, furniture, movement of objects and people) accelerate the aging process of foam materials (collapse of air bubbles in polyethylene foam pads), which also leads to a decrease in the effective thickness of the material and loss of elastic properties.

"Shumostop-S2" - slabs made of staple fiberglass. They are used as an elastic soundproofing gasket in building structures when installing “floating floors” with increased requirements for insulation of airborne and impact noise. See below for information on technology of use.

"Shumostop-K2" - slabs made of basalt mineral fiber. They are used as an elastic edge soundproofing gasket in building structures when constructing “floating floors” using “Shumostop-S2” slabs. See below for information on technology of use.

"Vibrostek-V300" is an elastic multilayer fiberglass. It is the basis for "Shumanet-100Super". Has the same acoustic characteristics. Used as an elastic gasket to reduce the transmission of impact and structural noise.

"Vibrostek-M" is an elastic multilayer fiberglass in rolls 100 mm wide and 30 meters long. Used as an elastic gasket to reduce the transmission of impact and structural noise. It is used when installing the ZIPS panel system, as well as when installing frame structures of soundproof ceilings, partitions and cladding made of gypsum plasterboard and gypsum fiber boards.

"Lutrasil" (spunbond) is a non-woven sound-permeable fabric. Used as a cushion layer when using glass/mineral wool mats/boards to prevent the emission of particles into environment.

Thus, it should be concluded that soundproofing materials themselves are not finishing materials and the acoustic purpose and characteristics are completely different. In addition, their use in soundproofing structures can only be justified on the basis of the opinion of an expert in the field of architectural and construction acoustics (acoustics engineer) with extensive professional experience in this activity.

Noise stop

Soundproofing slabs for the installation of “floating” floors

Description

The high sound insulation characteristics of the SHUMOSTOP slab system (ΔLn,w = 42 dB) for almost any interfloor ceiling design provide an impact noise level 20 dB lower than required by SNiP. This allows us to talk about real acoustic comfort, when the sound of a bottle falling on the floor in the room above is perceived in the room below as the fall of a light coin.

Application area

SHUMOSTOP slabs are used as an elastic sound-proofing layer in building structures when constructing “floating floors” with increased requirements for impact noise insulation. In this case, Shumostop-S2 slabs act as the main working layer, and high-density Shumostop-K2 slabs act as an edge layer designed to increase the stability of the floor base along the perimeter of the room and around the columns.

Installation technology

To ensure the stability of the floor base, made using Shumostop-S2 slabs, Shumostop-K2 edge slabs with a width of 300 mm are laid around the perimeter of the room, as well as around the columns. To prevent the leveling screed from coming into contact with the surface of the walls, a cushioning material (for example, Vibrostek or Shumostop-K2) is used along the entire perimeter of the floor along the walls, the height of which should be slightly greater than the thickness of the screed being installed. Shumostop-C2 slabs are laid on the floor slab close to each other, without a gap. A waterproofing layer (reinforced polyethylene film) is placed on the Shumostop slabs and lifted along the wall to the height of the edge of the cushioning material. Then they arrange a reinforced concrete screed thickness of at least 60 mm (with one layer of SHUMOSTOP) and 80 mm with two layers. The construction of the finished floor is performed on the screed. The plinth is mounted only to one of the surfaces - to the floor or to the walls.

Technology of use

When installing a “floating” floor from a parquet board or when laying it under linoleum, VIBROSTEK-V300 is laid without overlap, pressing the panels against each other. The seams are glued together with 50 mm wide tape. The panels are cut along the contour of the floor and are not placed on the wall. When laying parquet boards, 10 mm gaps are left near the walls, which are then covered with plinths. This ensures moisture circulation. When installing a “floating” screed to prevent it from coming into contact with the surface of the walls, cut strips of VIBROSTEK-V300 are laid along the entire perimeter of the floor along them. A separating layer (reinforced polyethylene film) is placed on top of the substrate and placed on the wall to the height of the edge of the material. To cut and cut VIBROSTEK-V300, you should use sharp knives used for laying carpets.

Contact our specialists and we will advise you on SOUND INSULATION issues; You can purchase the necessary materials from us.

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

The ability of a material to protect from noise will tell you the index of sound insulation – Rw.

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 structural elements Houses.
The key characteristics of soundproofing material are sound insulation and sound absorption. It should 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 the structure is extremely important. Often, builders use multilayer systems in which sheets of dense plasterboard 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-proofing – a combination of special design and material.

Review of popular soundproofing materials

Modern technologies make it possible to use simpler and more cost-effective materials that provide insulation from external and internal noise. Thus, 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.

More thin material are ISOPLAAT heat and sound insulating boards. Their thickness does not exceed 25 mm, and their sound insulation index is twice as high as that of ZIPS - 23 dB. In addition, ISOPLAAT is made from environmentally friendly coniferous fibers. The boards are mounted using glue and “breathe” well.

The thinnest panels are EcoZvukoIzol and Kraft - 12 mm and 13 mm, respectively. The first ones are made of a seven-layer cardboard profile with the addition of quartz sand, the second ones are made of wood fiber boards. Both are easily attached with ordinary glue. The sound insulation index of both is approximately 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, due to their small thickness, help preserve square meters. In fact, this is not entirely true - they only absorb impact noise, but do not insulate at all from airborne noise.

If you are thinking about what soundproofing material to choose for your apartment, then you are concerned about the issue of excessive noise in the premises of your home. Just as often as the rest of the room’s surfaces, craftsmen today try to make the ceiling soundproof. This at the same time allows you to achieve more impressive thermal insulation characteristics ceilings

Types of sound absorbers for ceilings

You can choose organic and inorganic materials for soundproofing work. Among the first are those based on polystyrene foam, particle board or ecowool. The use of such noise absorbers implies ease of installation, affordable price and environmental safety.

Soundproofing material such as polystyrene foam is found today, perhaps more often than others, in insulation systems. It perfectly retains heat in the room, but is of interest to rodents.

Among inorganic materials, stone wool can be distinguished, which is durable and safe for human health. The cost of this insulation is very affordable, which acts as a positive feature. Stone wool can withstand low and high temperatures ranging from -60 to +400 degrees. This indicates that this insulation copes well with high humidity conditions.

Work options

Soundproofing material can form the basis of different ceiling systems, for example, mineral wool can be installed in a hollow space suspension system. The canvases fit perfectly between the frame elements. But if you decide to use polystyrene foam, it is not recommended to use glue to attach it, since the slabs have a weight under which the material can move away from the base over time and cause even more noise. You can also use glass wool, but you should remember that this material must be well protected, since its elements can pose a danger to human health. In connection with this requirement installation work using glass wool can be accompanied by more significant labor costs. When using gypsum plasterboard as a finishing coating, you should Special attention pay attention to joining the sheets, since sound penetrates well through the cracks.

Soundproofing material is usually attached between the waterproofing, which is installed on the subfloor, and the base ceiling.

Soundproofing materials for walls

If you decide to get rid of noise in a room in a comprehensive manner by also sealing the walls, you can choose soundproofing systems, which are designated by the abbreviation ZIPS. They perform several functions at once. By installing them, you prepare the surface of the walls for subsequent finishing. This material contains an insulating layer and gypsum board. The panel contains several sound insulators, namely: gypsum fiber and mineral wool, the latter is sometimes replaced with glass wool. The thickness and combination of internal components may vary. The weight is 18.5 kg, while the dimensions of one canvas are 1500x500 mm. Thickness can vary between 40-130 mm. The described soundproofing materials can be secured using structural units.

Among the natural sound absorbers, we can highlight ISOPLAAT boards, which are based on coniferous wood fibers. The size of the canvas is 2700x1200 mm, while the thickness can be equivalent to 10-25 mm. The weight is very light and limited to 4 kg.

After installing such material, you will not have to prepare the wall for installation. finishing. It is recommended to install the described slabs using glue. They allow air to pass through perfectly, which does not create the effect of a thermos in the room.

Alternative soundproofing options for walls

When considering soundproofing materials for walls, we can highlight ISOTEX panels; they are based exclusively on natural components of coniferous trees and are characterized by excellent flexibility and elasticity. If you choose this method of dealing with noise, then you will have to work with canvases whose dimensions are limited to 2700x580 mm. With a thickness of 12-25 mm, the insulation weighs 1.2 kg, which ensures ease of installation. Such soundproofing materials for an apartment look great and do not imply the need for wall finishing after installation, since their outer side has decor in the form vinyl wallpaper or linen fabric. Installation consists of connecting the plates using a lock, and if necessary, cutting can be done using a construction knife.

EcoZvukoIzol panels have gained quite a high popularity among private craftsmen, this is due to the fact that this material is environmentally friendly, as it is based on seven-layer cardboard and quartz sand. The canvases are somewhat heavier compared to those described above: their weight is 10.5 kg, dimensions are 1200x450 mm. But they are easy to work with, despite their impressive weight. If you need to adjust the panel to size, you can use a hacksaw, and at the time of fastening you need to use an adhesive composition intended for drywall.

If you are looking for soundproofing materials for an apartment, then you can consider Wall panels, which are known as KRAFT. They have environmentally friendly wood fiber elements that are outside covered with wax paper, while the inside - corrugated cardboard. Their weight is 5.5 kg, which facilitates the installation process, but their dimensions are 2700x580 mm, which implies the need to enlist the help of another person before starting work. It is quite simple to glue the canvas, and after the composition has dried, you can begin decorative finishing.

Cost of wall materials

The listed soundproofing materials for walls have a lot of advantages, but sometimes it makes it difficult to make a choice. Perhaps the price will affect this. If we compare the above materials, then ZIPS costs 1300 rubles/m2. But "EcoZvukoIzol" will cost less - 900 rubles/m 2. ISOTEX is even cheaper - within 600 rubles/m2, the final cost in this case will depend on the type of decorative coating. KRAFT is the penultimate among materials in the most affordable price category - 250 rubles / m 2. And the leader in the matter of democracy is ISOPLAAST, its price is 150 rubles/m 2.

Sound absorbers for floors

When choosing sound absorbers for the floor, the consumer, as a rule, pays attention to heat and sound insulation materials. A cork substrate, which is placed under the finishing coating, copes well with such tasks. This material is based on natural cork chips, which makes the soundproofing layer completely harmless. In addition to the fact that cork will combat noise, it will last a long time, since it does not rot and mold cannot appear or develop in it. Cork does not attract rodents. The material is chemically inert and has a lifespan of 40 years. It can reduce noise levels by approximately 12 decibels.

The listed characteristics of soundproofing materials force consumers to incline their choice in their direction. As alternative solution can choose cork backing, which contains rubber elements. Synthetic rubber in tandem with cork does the job perfectly. The degree of sound absorption here is more impressive and is approximately 18-21 decibels. But you will have to pay more for such material.

The best soundproofing material made from cork is one that contains bitumen along with the main ingredient. The advantage of the substrate in this design is that it does not require additional waterproofing works, which cannot be said about the above. But this will require certain skills, because bitumen stains hands and clothes.

Foamed polyethylene for flooring

When considering the soundproofing properties of materials, it is worth paying attention to polyethylene foam. It is also customary to lay it under a finishing coating, for example under a laminate. You can choose one of several varieties of this material. Thus, polyethylene with chemically bonded molecules and cross-linked polyethylene have more impressive soundproofing characteristics compared with non-crosslinked polyethylene. Laying this material requires mandatory waterproofing, since it can become moldy when exposed to moisture. It is advisable to lay it with some clearance, since under mechanical loads the material loses up to 2/3 of its thickness, which causes a decrease in noise-absorbing properties.

Schumanet for floors

When considering the types of soundproofing materials, you will probably come across the Schumanet soundproofer. It is a composite substrate based on a multicomponent material. It contains three layers, the first of which is polyethylene, which protects against water, the second is polystyrene foam granules, while the third is a film that allows moisture particles to penetrate into the polystyrene foam. Afterwards it is discharged around the perimeter of the room through the ventilation slots. The lifespan of the material is about twenty years. It should be installed using the rolling method; adhesives are not used.

In addition to those listed, extruded polystyrene foam is used to combat noise, which acts as the densest type of foam. It is practically like wood, it does not absorb moisture at all, it is easy to work with during the installation process, in addition, it is easy to cut using a knife. It will last about half a century. When considering soundproofing materials for walls or floors, you can choose this one.

Speaking of the above, the most impressive degree of noise absorption is provided by Schumanet-100 gaskets. At 3mm thick they can reduce noise levels by as much as 23 decibels, while if you want even more impressive results, you can use 5mm material and the sound will be reduced by 27 decibels. The gaskets described are based on fiberglass, which has a special weave. If the manufacturer used staple weave, the noise will be reduced by 42 decibels. If you decide to cover these pads, then you need to provide a gap around the perimeter of the walls, the width of which is 1 cm, which will be necessary to remove moisture.

Universal sound absorbers

When choosing soundproofing materials for the ceiling, floor and walls, you can also select fiberboard. It can be used in premises of any purpose. This material is based on wood fiber and cement. In addition to the above ingredients, you can also use synthetic fibers. In order to form an acoustic surface, acoustic fiberboard should be used. It is characterized by an increased noise absorption coefficient, the level of which is 40 percent.

Stone wool also does an excellent job of absorbing noise; the sound absorption coefficient can be equal to 99 percent. It copes well with changes in temperature and humidity, so it can be used in almost any room.

Methods for suppressing impact noise

Soundproofing materials for apartment walls, which were described above, can cope with airborne noise. But if there is a need to eliminate impact noise, then you can use a floating floor system that is not rigidly connected to the subfloor. An insulating layer is used as the basis of this system, it can be the one described above stone wool. If the sound insulation of all surfaces of the room was not enough, then special attention should be paid to doors and windows. In this case, PVC profiles come to the rescue, which have very good noise-absorbing qualities. As a rule, there is an inert gas between two windows in the hollow space. The most common of these is argon.

The range of modern sound absorbers is large, but it is worth remembering that they should be used comprehensively, in addition, sometimes the quality of sound absorption depends on the correct installation of the material. Only by following the installation technology will it be possible to achieve a positive result, and your neighbors will not disturb you, just as you will not disturb them, which is very important, especially in apartment buildings.

Soundproofing of residential premises is becoming more and more relevant every year. And every homeowner wants to choose the best soundproofing material to protect against outside noise. Although it is difficult to choose them based on the “good or bad” principle, since many of them have a specific purpose and, to one degree or another, fulfill the assigned tasks.

So what is soundproofing? As a rule, noise and sound insulation is a complex multilayer structure, including dense layers that reflect sound waves and soft layers that absorb extraneous sounds.

In this regard, neither mineral wool, nor membrane, nor panel materials should be used as independent sound insulation.

At the same time, it is a mistake to assume that heat insulators (cork, PPS, PPE, etc.) are capable of fully fulfilling the role of noise protection. They are not able to stop creating a barrier against the penetration of structural noise.

Even worse than that– if sheets of polyurethane foam or polystyrene are glued to the wall under the plaster, then this design will increase the resonance of incoming noise.

• Resistance to rotting, moisture and temperature resistance (properties do not change even at t°-20), durability.
• Versatility due to the property of stretching.
• Certification according to Russian and European standards.
• Environmental safety due to the absence of phenol-containing substances.
• Reduction of airborne noise up to 28 dB.

Flaws:

• Possibility of installation - only adhesive.
• Not applicable as an independent material for sound insulation.

The cost is above average.

Schumanet

Mineral wool boards of the Schumanet series are designed for wall and ceiling frame soundproofing systems for subsequent finishing with facing materials (plywood, plasterboard or fiber sheets, chipboard).

• Resistance to humidity, formation of mold and mildew, durability.
• Excellent vapor permeability and minimal thermal conductivity.
• Complete fire safety and non-flammability - classes KM0 and NG.
• Compliance with high sound absorption classes - A/B at any frequency, reduction of structural and airborne noise waves from 35 dB.
• Russian Federation certification.
• Easy to install due to its elastic properties.

Flaws:

An increased degree of phenol emission (slightly exceeds the permissible limit), that is, environmental friendliness is in question.

High cost due to the need to purchase many additional items. elements, the need to strictly follow the installation instructions.

ZIPS panels

The panel system from the manufacturer Acoustic Group appeared at the very end of the last century. This is a multi-layer structure, the composition of which varies depending on its purpose.

For ceiling and wall surfaces, tongue-and-groove joints are used as a base. plasterboard sheets, for floor - gypsum fiber. They are supplemented with fiberglass or basalt slabs.

To a large extent, vibration units made of polymer and silicone prevent the transmission of vibration and noise waves. Flammability degree G1 (low flammability).

Advantages:

• Durability, efficiency and biostability.
• Low thermal conductivity.
• The absence of inter-plate gaps during installation is ensured by the tongue-and-groove type of connection.
• There is no need to use adapters when attaching plates.
• Compliance with GOST requirements.

Flaws:

When mounted on a wall, the slabs can resonate by 2-3 dB with incoming and outgoing low-frequency noise up to 100 Hz.

During the installation process, many components are required, which significantly increases the final cost of installation.

SoundGuard Plates

A fairly effective product, attractive at an affordable price, produced by an alliance of experienced manufacturers who have been known on the Russian market for many years. Prefabricated noise protection structure includes:

• Drywall Volma,
• SoundGuard profiled board (consists of plasterboard with mineral-quartz filler and a cardboard cellulose panel),
• Frame profile.

According to the degree of flammability, they belong to group G2 (moderately flammable), toxicity T1 (low). The advantages of SaunGuard panels include:

Compliance with all safety requirements and certification of the Russian Federation.

Versatility - the slabs are suitable for any wall and floor bases.

Minimum thermal conductivity.

Good sound insulation performance ( airborne noise– up to 60 dB, drums – up to 36).

Easy installation, the ability to choose the installation method (adhesive, frame, using plastic dowels).

Disadvantages:

• Lack of moisture resistance properties.
• There are few sales representatives in Russia.
• High prices.
• During the cutting process, the mineral filler is shed. This necessitates the need to cover the edges of all slabs with tape or tape.

In addition, if the panels are used as an independent sound insulator, then the degree of interference with impact and airborne noise does not exceed 7 dB. Like ZIPS, panels can resonate with low-frequency noise.
