Comfort in the house is created from several components, the most important of which is silence. Noise from the street or neighbors apartment building can cause irritability, deterioration of both mood and well-being. In a private house, everything is much simpler, since homeowners are able to independently regulate the noise level, apply effective methods to get rid of it, and create the most comfortable conditions for themselves.
Soundproofing the ceiling in a private house is important even if this ceiling is not the floor for the actively used second floor.
The need for soundproofing the ceiling in a private house
Speaking about the need for soundproofing work in a private house, it should be remembered that a systematic approach is important, that is, taking into account all types of noise and the ways it enters the room. And if low-frequency (impact) noise enters the room mainly through the floor and walls (if the room above the ceiling is not in use), then high-frequency noise also enters the room through the ceiling.
Therefore, it will be impossible to achieve the desired peace and quiet in the house just by protecting the walls. And by correctly combining layers of hard (concrete, brick) and soft (polystyrene, basalt wool, cork and others) materials in a multilayer “pie”, you can get the maximum result.
ADVICE. Do not think that effective soundproofing of the ceiling can always be achieved by simply increasing the thickness of the laid homogeneous material. It is much more important to choose the right soundproofing technologies. For example, for an exploited attic or attic, the use of a “floating floor” in combination with moderate protection of the first floor ceiling will be quite effective.

Principles of effective soundproofing
Experts advise starting any soundproofing work by determining the conditions for the effective operation of certain methods. In order for the structure to be constructed to really protect against any noise, it must be:
- Multilayer. The more layers with different densities will be in the protective cake of the ceiling, the more difficult it will be for the sound to reach the room.
- Plastic and elastic. soft materials they transmit sound much worse, therefore they protect against noise.
- For protection against low frequency noise- quite heavy, because the higher the mass of the building envelope, the worse the vibration passes through it.
- Properly built. All materials used for soundproofing must be used in strict accordance with the technical requirements. The frame on which they are held must be carefully calculated.

Soundproof materials: advantages and disadvantages
ADVICE. Among the materials based on basalt wool, brands such as Acoustic Butts, Shumanet BM, Ecover Light.
Acoustic Butts
In the wake of attention to environmentally friendly technologies, wood-based materials are very popular - boards made on the basis of coniferous wood without any harmful additives. The ease of installation of such structures (they are glued to the ceiling in the same way as foam plastic) and a high degree of noise protection make this material in demand in residential areas - bedrooms and children's rooms. But the complexity of production makes Isoplast and Isotex plates very expensive for the average man in the street.
Shumanet BM
Another option for soundproofing a ceiling is cork. Panels made of this natural material are able to provide sufficient sound insulation with a relatively small thickness of the protective layer. When installing the cork, it is important to follow the technology, namely, first mount the frame for false ceiling, and then install drywall boards with cork panels glued to them.
Ecover Light
ADVICE. It is possible to soundproof the ceiling from the side of a rarely used attic using ecowool - a light and loose material based on waste paper, which is applied in a layer of about 5-7 centimeters. But such a process can only be carried out by specialists with equipment for spraying the material.
The group of rare environmentally friendly materials for soundproofing the ceiling includes natural felt and coconut cloth, which are not used so often due to their high cost, but are well suited for children's rooms and bedrooms.
Soundproofing Green Glue
Among the current innovations, liquid sound insulators should be noted, which are ideal for improving the properties of a double gypsum plasterboard ceiling: for example, the Green Glue material laid between the gypsum boards is effective. An equally attractive result is demonstrated by a soundproof membrane (for example, Tecsound or a PSI canvas). The main problem of working with this material is the complexity of its installation and the need for a sufficient height of the room, since the membrane requires the installation of a double crate.
Noise insulation of walls in an apartment, modern materials for which today can be found in hardware stores, is becoming more and more relevant. This is explained simply - fences in multi-storey typical houses are not able to fully 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, not allowing him to get 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 soundproof 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 due to recent production technologies.
To date, very a large number of new soundproof materials, and it is simply impossible to cover the characteristics of all on the scale of one article. Therefore, attention will be focused on the most effective ones, which are used specifically in an apartment.
Thin soundproofing 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 spend precious inches of living space?
In this case, the innovative MaxForte SoundPRO thin soundproofing material will suit you. It has a thickness of only 12 mm, while in terms of its characteristics it is able to 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 of the Faculty of Physics of Moscow State University took part in the development of the material. In the manufacture of MaxForte SoundPRO, all important points for the efficient operation of the material: the optimal density was selected (with a low density, the sound will pass through, if it is too high - along the “skeleton”), the length of the fibers, 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 and any adhesives. Therefore, in addition to excellent soundproofing properties, MaxForte SoundPRO is safe for health.
MaxForte SoundPRO gives an increase in sound insulation from both air (loud TV, a crying child, screams of neighbors) and impact noise (noise from trampling, rattle of furniture, falling objects). It can be used for soundproofing ceilings, walls and floors, which will give a significant increase of up to 64 dB!
Installation of thin noise insulation is very simple, and not only professionals can handle it, but anyone who has ever held a hammer drill and a screwdriver in their hand.
MaxForte SoundPRO is mounted on the wall using ordinary plastic dowel mushrooms, which can be purchased at any hardware store. It is hung on the wall using the butt-to-butt technology, after which it is covered with a layer of GVL (gypsum fiber sheet). All seams of the sheets must be glued with a special vibroacoustic non-hardening sealant. After the soundproofing is sewn up with a layer of GKL (gypsum plasterboard). The seams of the GVL and GKL sheets should be in a run, that is, they should not match.
Visually about the installation of thin sound insulation MaxForte SoundPRO you can see in the video.

Thin wall soundproofing panelsSoundGuard EcoSoundIsol
EcoZvukoIzol SoundGuard panels are a unique material for soundproofing walls and ceilings, which allows you to achieve silence in the apartment and not lose usable space.
SoundGuard EcoZvukoIzol panels are made of a durable multi-layer cardboard profile 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, for example brick wall or steel door much worse). In addition to weight, due to the fine fraction, quartz sand perfectly dampens and absorbs almost all sound frequencies - from air to shock.
How to mount panelsSoundGuard EcoSoundIsol?
Installation of panels is very simple and almost anyone can handle it. are attached to the wall using SoundGuard DAP acoustic dowels, which are hammered into holes pre-drilled through the panel in the wall. After that, all seams and joints are smeared with sealant and the entire wall is sewn up with drywall.
Mineral noise absorbing material "Shumanet-BM"
This soundproof the material made from basalt fibers is considered to be a premium grade mineral sound absorbing board. One side of the mat is laminated with a fiberglass layer, which helps to preserve the integrity of the slab and keep 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 by perforated acoustic panels.
Packing of soundproof boards "Shumanet" 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:
| Indicators | |
|---|---|
| Standard plate size (mm) | 1000x500 or 1000x600 |
| Plate thickness (mm) | 50 |
| Material density (kg/m³) | 45 |
| Number of boards in a package (pcs.) | 4 |
| Area of boards in one package (m²) | 2.0 or 2.4 |
| Weight of one package (kg) | 4.2÷5.5 |
| Packing 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, in% of the total volume | Not 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 the Russian Academy of Architecture and Building Sciences.
The basis of "shumanet" are 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 stretch and suspended ceilings, and, of course, walls and multilayer partitions made in the form of a sandwich of drywall, plywood, fiberboard and other sheet materials.
Soundproofing walls using "Shumanet BM"
Installation of plates of this noise insulator takes place according to 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 an additional insulation.
Work is carried out in the following sequence:
- On the prepared one, markings are made to secure the elements of the crate. Since the width of the mats is 500 mm, and they should stand between the bars by surprise, 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.
- Further, the elements of the crate themselves are fixed, but at the same time, in order not to weaken the basic qualities of the soundproofing material, experienced craftsmen advise you to follow a number of simple recommendations:
- For lathing, it is best to use a wooden beam, and not metal profiles, since metal is a good conductor of sound, it can resonate, and wood tends to dampen sound waves.
- In addition, in order not to create bridges for the passage of sound, it is recommended to make spacers between the wall and the lathing bars from a thin soundproof material, for example, felt or strips of basalt wool 8 ÷ 10 mm thick.
- If, nevertheless, a metal profile is chosen for the crate, then it is better to move it away from the wall with a soundproof gasket by 12 ÷ 15 mm.
- In the event that the area soundproof the room is large enough, and it is possible to take out the crate for sound-absorbing material and cladding 100 mm from the wall, then you can use special 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, which effectively dampens vibrations without transferring them to the frame guides.
Special suspension used for soundproofing work If a guide bars fixed in the above way, then the sound insulator mats are mounted in two layers. The first of them is installed behind the elements of the crate, close to the wall, and the second - between the guides.
Two-layer placement of shumanet panels - Ultimately, upon completion of the installation of the Shumanet BM panels, the walls should look like this:
Next, over the mats soundproof material is fixed vapor-permeable diffuse membrane. Then they proceed to the installation of drywall or plywood sheets, which, in turn, will become the basis for the implementation finishing works. However, it is quite possible to replace this layering by fastening directly to the guide rails of a wooden decorative lining.
Next - the wall is tightened with a diffuse membrane and sewn up with drywall 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.

"Teksound" - a new direction in sound insulation technology
Texound is not yet as popular as mineral wool or polystyrene foam, as it is a relatively new sound insulator. The most important advantage of "texound" over others soundproof materials is that it practically does not “steal” the useful area of \u200b\u200bthe room, since it has a small thickness.
The main advantage of "Teksound" 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 craftsmen use "texound" in combination with thermal insulation materials, and such a bundle only increases the effectiveness of its use. But, unfortunately, the premises in apartments most often do not have extra space that can be given over to a “powerful” multi-layered sound and heat-insulating structure. In this regard, a material was developed that is able to protect rooms from excessive noise and not reduce the size of the room.
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 not be possible to achieve the desired result.
The “texound” was developed in Spain by specialists from the well-known company TEXSA, and its mass production began there. industrial production. 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 base component is calcium carbonate (CaCO³). Aragonite is very rich in this compound. In addition, calcium carbonate is the main constituent of many calcareous rocks, including chalk, marble, and others.
Harmless polymer compounds are used as binding components, and as a result, high-density membranes are obtained, but at the same time very flexible and elastic, with pronounced viscoelastic qualities, which is extremely important for sound insulation of complex building structures.
Sound insulation of rooms with this material is very effective even if canvases with a very small thickness are used. "Teksound"Able to absorb and scatter even sound waves of high intensity, which come not only from the outside, but are also created inside the room, for example, with very loud music.
Texounda canvas covered with a protective film "Teksound" is produced in canvases (membranes) and goes on sale in rolls packed in polyethylene. It has the following technical and operational characteristics:
| Name of material parameters | Indicators |
|---|---|
| Material density (kg/m³) | 1900 |
| Average web weight (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:
- "Texound" is resistant to temperature extremes. Its elasticity does not decrease at all even at negative temperatures up to -20 ° C .
- The material has a pronounced flexibility and plasticity, and this "Teksound" is somewhat reminiscent of rubber.
"Texound" with its plasticity resembles dense rubber - The material is resistant to moisture and will never become a zone of mold or fungus, as it has antiseptic properties.
- The operating time of the “texound” is not limited.
- "Teksound" is perfectly combined with other materials, and can be applied in a complex system.
"Teksound"Subdivided by its thickness, size and shape of release, may have additional layers that improve its characteristics. The main brands are presented in the table:
| Name | Noise isolator release form | Linear parameters of the material, mm |
|---|---|---|
| Texound 35 | rolled | 1220×8000×1.8 |
| Texound 50 | rolled | 1220×8000×1.8 |

Texound installation
Almost any base is suitable for mounting this material - concrete, drywall, 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 qualitatively applied 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 done 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. For mounting " texound"A special mounting adhesive is used, which is sold in liquid form, ready for use, in canisters. After greasing, it is necessary to wait 15÷20 minutes until the glue sets.
Marking and cutting canvases "Teksounda" - Further, the soundproofing material itself is mounted on the glued wall, which must be measured and cut off in advance, and also pre-lubricated with glue.
Special glue is applied both to the surface of the wall and to the Texounda canvas itself. - If self-adhesive material is purchased, then installation will be much easier, since you will not need to lay it, and you just need to remove protective film and attach the material to the wall.
- Next, the “texound” sheet must be pressed as tightly as possible to the surface, and then additionally walk over it with a roller. This must be done in order to achieve its best adhesion to the wall surface over the entire area, without leaving air bubbles.
Welding the Texound joints with a gas burner - Cloths "Teksounda"Be sure to overlap, by about 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 a gas burner - while adjacent sheets are welded. If at least small gaps are left between the canvases during installation, then the effectiveness of sound insulation will be significantly reduced.
Fully texounded doorway - If the Texound installation is carried out 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 solid sheet from wall to wall.
- After gluing the canvas, if necessary, it is additionally fixed on the wall with fasteners - “fungi”, the very ones that are most often used for mounting polystyrene foam or mineral wool.
The second option - with the use of 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:
- On the primed wall along the edges, the crate frame is fixed.
Frame for "Texound" along the perimeter of the wall - The next step is to immediately glue Texound on the entire wall in one version, and in the other, heat-insulating material is preliminarily laid. However, the first method shows a higher efficiency for sound insulation.
- If thermal insulation is adjacent to the wall, then "texound" is first fixed with "fungi", and then additionally pressed with metal hanger strips.
Fixing the "Texounda" canvases with "fungi" dowels - To achieve the required place for installing the insulation material, the metal profile of the frame is fixed in suspensions at a distance of 40 ÷ 50 mm from the wall. In this case, it is necessary to set each of the profiles according to building level, otherwise the casing of the frame will not be even.
Installation of a metal frame on top of the soundproofing sheets - The next step is the installation of insulation. The most environmentally friendly of suitable insulation materials that can be installed independently is basalt-based mineral wool. If financial funds, then you can use the above-described "Shumanet BM", which is not only noise absorbing but a good thermal insulation material.
- It fits tightly between the racks of the crate 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 heater vapor permeable diffuse membrane.
- The next step is . In some cases plywood or OSB sheets are used for sheathing.
- The sheets are fastened to the racks of the crate by 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 caps of the self-tapping screws are sealed with putty.
- Further, the surface is primed and puttied completely, and after that you can decorate the walls with decorative material.
Drywall - the most convenient material for leveling walls
The wall that received soundproofing and insulation protection, it is necessary to prepare for further work- achieve flat surface, which will become the basis for finishing materials. As well as - in special publications of our portal.

Existing schemes for mounting "texound"
Masters use various installation schemes for this sound insulator. Depending on the convenience of performing work, the area of \u200b\u200bthe room and the required efficiency of wall insulation from external noise, you can choose any of them. The only drawback of these structures is their thickness, which even in the best case will be at least 50 mm.
First option
This design will have a thickness of 50 mm.
- They begin to mount it with the fact that the prepared metal profiles from the side of their contact with the wall are pasted over with self-adhesive tape "Teksound 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.
- Further, 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 onto the sheets of drywall, on their inner side. In this case, Texound 70 is well suited.
- Thereafter. drywall is fixed on the racks of the frame, and its seams are sealed with putty.
Second option
The thickness of the structure with this option will be 60 mm.
- In this case, a thin heat insulator is first fixed to the wall. You can use foil insulation by setting it with a reflective surface towards the room. The insulation should cover the joints of the wall with the floor and ceiling, that is, go to them by 150 ÷ 200 mm.
- On top of it is made installation of a metal frame, which in the same way as in the first version of the design, it is attached to the wall.
- Further, insulation mats are placed in the frame, which are covered with drywall with Texound 70 glued to it.
It should be noted here that the heat-insulating material attached to the wall can be replaced by "Teksound FT 75", which has an additional layer of felt.
Third option
The thickness of the third design option is 70 ÷ 80 mm, as it consists of more layers.
- The first layer to the wall is installed heat-insulating material.
- The second layer is the Texound sound-absorbing membrane.
- A crate is mounted on top of it.
- Then the insulation mats are installed.
- Sandwich panels are fixed to the structure with the last layer, consisting of two sheets of drywall, 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 right choice, having determined the thickness and the best form of the Texound release.

Use of foam rubber mats as soundproofing
Acoustic foam can be called the most effective affordable material for soundproofing walls in an apartment. Due to its porous structure, this material perfectly absorbs and scatters sound vibrations.
Acoustic foam rubber is able to neutralize two types of noise - sound and vibration waves, that is, it muffles the sound and scatters low frequencies arising from surface vibrations, for example, knocking or "bass" of music.
The material is quite durable and can be mounted both as an independent soundproofing material and in combination with drywall. Foam mats are available in a wide range of sizes and can be embossed or have a flat surface.
Foam rubber is made by pressing polyurethane foam, after which it is cut into standard blocks with a size of 1000 × 2000 mm. The thickness of the mats varies from 10 to 120 mm. Domestic material is produced in two or three colors, while imported options have a more diverse range of colors, including 10÷12 colors.
Material relief types
Types of relief pattern of acoustic foam can be different. The depth of the relief determines both the total thickness of the material and its noise-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 soundproofing 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, it is most often used in large halls. | |
| "Pyramid" | ||||
| For moderate wall protection against the penetration of high and medium frequencies. | Standing wave protection in small spaces. In combination with traps for low frequencies, they can completely soundproof the room. | It is used for rooms of any size and is used in conjunction with additional soundproofing elements, such as sound traps. | Same features as wedge material type |
There are other, less frequently used acoustic foam elements.
| Name of relief type | Characteristics |
|---|---|
| "Peak" | This relief of mats is less popular and has an unusual pattern. Its lack of demand is explained by lower soundproofing qualities than those of the materials mentioned above. |
| "Bass Trap" | Waves that have a low frequency are harder to dampen because they are longer. For this, bass traps are installed in each corner of the room, which are designed for rooms of any size. |
| "Traps of high and medium frequencies" | These elements are installed in the halls big size. They are designed to capture mid and high frequencies, and create the effect of scattering low frequencies. They are installed in a vertical position, but if the blocks are cut in two and placed at the corners, they will become traps for low frequencies. |
| "Corner Block" | Corner blocks are made in the form of a triangular beam. They are installed at the corners of the room and at the junctions of two surfaces, and also serve to dissipate low frequencies. |
| Decorative ceiling tiles | Available with and without embossed pattern. They are designed to change the relief and shape of the ceiling, with the help of which an additional soundproofing effect is achieved. |
| Insulating wedges | They are used to reduce vibrations from studio equipment and are used as a substrate under 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 of panel houses choose foam rubber to reduce the sound transmission of walls. Due to its high sound-absorbing and scattering qualities, this material is able to make the room almost completely soundproof, provided that it is mounted 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 its soundproofing qualities at all when it is closed with drywall. The main condition in creating such a design is that the foam mats themselves must be glued directly to the wall base, without any lining.
Soundproofing acoustic foam walls
Installing foam rubber on the walls is not too complicated, so you can easily do it yourself. In this case, it is worth considering the most acceptable method of soundproofing for the conditions of the apartment, but it should be noted right away that the area of the room will decrease somewhat.
Installation work is carried out in the following sequence:
- In order for the foam rubber to stick easily, it is best to prime the wall surface and dry it well.
- Next, the mats need to be fixed on the wall. They must fit snugly against its surface, otherwise the sound insulation effect will be partially lost.
- You can glue foam mats on a 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 the frame lathing from metal profiles or wooden beam. Frame guides are fixed at a distance of 50÷60 mm from the wall.
- Racks are mounted in the recesses of the relief pattern directly to the wall. Mounting holes are drilled straight through the foam.
- After fixing the frame of the crate, drywall sheets, plywood, PVC panels or other finishing materials are fixed on the rails. This will in no way reduce the efficiency of the sound absorption of the foam rubber layer, since it will be the first to receive all sound waves coming from outside, absorb them and scatter them.
- In the same way, the foam rubber is mounted on a crate, and then one of the types of suspended ceilings is fixed on it.
- Logs are laid on the floor over acoustic foam rubber, on which a plank or plywood floor is laid. Further, if desired, laminate, linoleum, carpet or other decorative coating can be laid on plywood.
It should be noted that the installation of acoustic mats does not require serious preparatory repair work, and if it is decided to leave the foam panels in the open, then their installation will generally take no more than one day.
Exposed material will require frequent cleaning with a powerful vacuum cleaner to keep a large amount of dust from accumulating inside this porous material. In the event that one of the panels for some reason has moved away from the wall, it can be quickly glued into place without any special preparations.
In addition to the considered soundproof materials, others are also presented in the assortment of building stores. But today, acoustic foam rubber, texound membranes, shumanet plates and similar sound insulators can be called the most effective and safest for installation in an apartment.
How can you protect yourself from noise?
There are 2 options here:
- Ceiling insulation in your room. We recommend mounting the frame system on vibration-isolated hangers. Also, a slightly less effective, but still working option may be the use of ZIPS panels. The disadvantage of ZIPS panels is the lack of full vibration decoupling from the insulated surface. For those who want to avoid plastering works, you can combine the installation of the frame with the installation false ceiling. If you do this at the same time, you will also not lose extra centimeters in the height of the room. Especially since today there are fabric options that look like a perfectly plastered ceiling. We use German stretch fabric D-Premium Descor. His device adds only 3-4 mm of thickness.
- The second approach is isolation from neighbors. We are talking about floating floor technology, effective against airborne and, first of all, impact noise. The main thing is that the neighbors are not against its installation.
When might additional wall insulation be required?
If the walls are a noise transmission channel. We are talking about those situations where the customer is more concerned about impact noise, and in the room on top instead of a floating floor is laid ceramic tile, laminate without backing or something similar. In this case, the shock wave is transmitted from the ceiling to the walls, so they become an additional conductor of sound and exacerbate the problem. So, they also require isolation from noise.
What is a frame soundproofing system?
Frame soundproofing is mounted on site and consists of several layers.
- First of all, the frame is assembled: Knauf profiles are attached to the surface using vibration-isolated or vibration-damping hangers.
- The frame is filled with slabs of Rockwool basalt wool, the task of which is noise absorption: its multidirectional fibers with air voids scatter the sound wave, converting noise energy into heat. So in the end, noisy neighbors make your home ... warmer.
- From above, the frame is sewn up with a solid sound-reflecting layer. These can be drywall sheets (GKL), or more massive sheets of weighted acoustic gypsum fiber, which have a higher sound reflection coefficient. Reflecting from them, the sound waves extinguish the oncoming ones, and the “residue” of the noise returns to the cotton wool.
- If necessary, the sheathing can be additionally weighted with a layer of panels with sand - SoundGuard EcoZvukoizol or Sonoplat, or with a membrane if there are thickness restrictions. It should be noted the relative high cost of these materials, despite the fact that their density (1300-1400 kg / m³) is comparable to the density of gypsum fiber (1254 kg / m³). Those. if you are willing to give up a few extra mm of thickness to save 30% of the total cost, you can completely get by with an additional sheet of gypsum fiber.
It is this sequence, from the point of view of physics, that most effectively dampens sound waves. Thus, the frame system increases the absolute vibration isolation by R w =14 - 25 dB, that is, it reduces the sound volume by 3-5 times.
What is the essence of the frameless system?
This concept includes options that are attached directly to the ceiling, without a frame device. Of those presented on the market, only multilayer soundproof panel systems ZIPS deserve attention, which are sound absorbers made of stone wool and plasterboard glued together. Due to a number of technical nuances, they can only be used by performing overhaul apartments. The inability to flexibly combine the quantity, thickness and type of materials limits its soundproofing characteristics to relatively low values.
Also, some mistakenly understand frameless options as roll or membrane sound insulation, or the option of mounting stone wool on fungi. The effectiveness of this approach is practically zero, because these materials are provided by manufacturers only as part of complex frame solutions.
Why is it more often preferred to frame rather than frameless system?
The ZIPS system has serious drawbacks:
- The rigid connection between the ceiling and the panel increases the transmission of vibration and noise, especially impact noise.
- The mounting surface must be perfectly flat, otherwise the gaps remaining under the panels will transmit sound.
- If the stretch fabric is not included in your plans, the ZIPS system requires re-plastering.
Thus, the preparation of the surface for the installation of frameless sound insulation and finishing increase the price per meter and the timing of the work. Therefore, it is better to install such a system during the repair period and provided that the noise level is not high.
Why is ceiling soundproofing different from wall soundproofing?
Noise "vertically" is not only and not so much loud speech or music (that is, airborne noise). From above, we are often disturbed by the sound of footsteps, the stomping of children, the sound of a ball or falling objects. This is shock noise, and it spreads differently: not through the air, but through concrete floor and walls. Structural way sound transmission requires "its own" methods of isolation.
What determines the price of soundproofing the ceiling in a turnkey apartment?
The following factors affect the cost of the service:
- surface area to be insulated (prices are per square meter);
- choice of technology: frame or frameless design;
- the composition of the "sandwich", that is, what materials and how many layers will eventually be required to solve the problem;
- additional installation of a tension web;
- the need for dismantling or preliminary repair work.
Is it obligatory to visit a specialist at home or can an order be placed by phone?
Even if you know the parameters of the room well, they are rather abstract for drafting a project. First, the engineer must correctly set the task, determining the nature, noise level and channels of its distribution, choose the optimal design and discuss individual wishes (in terms of materials, timing, etc.). It is possible that the area of the insulated surface will change. It is impossible to resolve all these issues over the phone.
Can Rockwoool Acoustic panels be replaced with another material?
It is possible, but this may affect the effectiveness of the design. In addition, its cost will increase. As a result, instead of saving, the customer can get a more expensive and less reliable option.
The experience of the work performed proved the high sound-absorbing properties of Rockwoool Acoustic wool and the optimal price-quality ratio. Note that almost all varieties of Russian-made soundproofing wool are produced at one enterprise - the ROCKWOOL plant in the city of Zheleznodorozhny, Moscow Region. So your own search for “something new” will still lead you to the materials of this manufacturer, only repainted and in a different package, with a higher cost.
Ecology of consumption. House: The "cardboard" nature of many domestic buildings has long become a byword. So that the neighbors from above do not bother with the details of their life, it is recommended to arrange at least basic sound and noise insulation of the ceiling.

Types of noise and methods for eliminating them
In the context of construction and repair, noise is divided into two main categories: structural and airborne, the name corresponds to the way they are transmitted. The sources of each type of noise also usually differ. Air - this is music, the human voice, the sounds of animals and working household appliances. Such noises are neutralized by damping air vibrations in a layer of porous, easily compressible material.
Structural noise, otherwise called shock or structural noise, occurs when there is an intense impact on various parts of the building structure. An example of such noise is the rattle from washing machine, the sound of heels, although the most infamous is the noise from impact drill or perforator. The propagation of noise of a structural nature is eliminated with the help of damper inserts at the junctions of one part of the structure to another, for example, between the ceiling and the armored belt of the wall.
In addition, in fact, even structural noise is perceived by a person as airborne, that is, at some point the building transmits vibrations to the air. The secondary way of soundproofing can be to dampen this vibration over the entire area of communication between walls and floors with the space inside the apartment, however, this method is considered more costly in terms of material consumption.
You should come to terms with the fact that it will not be possible to completely eliminate the penetration of noise into the apartment from the outside, just as it will not be possible to achieve complete absorption of sounds that occur inside the room. However, it is quite realistic to bring the sound absorption of walls to the standards indicated in SP 51.13330.2011. Thus, the optimal degree of sound insulation of walls is about 80–90 dBA for low-frequency noise (walking, impacts) and half as much for high-frequency noise (music, voice).
Does a stretch ceiling provide any benefits?
When working with a stretch ceiling, we are faced with a flat canvas enclosed in a frame of a baguette profile. Unlike suspended ceiling structures, the only way to transmit structural vibration is by attaching the fixing profile to the walls.
The propagation of low-frequency structural noise through the ceiling is prevented by gluing a damper tape under the mounting profile. If this is not done, you can get a kind of speaker the size of the entire room. Note that not all frequency ranges will be amplified through the ceiling, for example, high-frequency noise is damped due to the elasticity of the film.
With airborne noise and structural vibration of the ceiling, everything is somewhat worse: the stretch canvas practically does not prevent their spread and even enhances it. At the same time, the plane of the draft ceiling remains completely free for the installation of any kind of sound insulation of arbitrary thickness.
Dependence on the type of building
Work to eliminate structural noise must be planned in accordance with the design of the building. In the frequent case, the junctions of walls to ceilings and the features of sealing joints and technological cavities require the most attention. In some cases, you can even come to the conclusion that surface mounting of sound insulation will not give the desired effect.
A classic example of this is a panel house with a single-layer ceiling with hollow slabs. Acoustic resonance often occurs in such buildings due to the rigid abutment of the slabs to wall panels. The best way out is not soundproofing the ceiling, but cooperation with neighbors from above in order to install a floating floor for them.
Frame floors without filler can be modified by adding polystyrene chips or sawdust, which will have a good effect on their sound absorption. In some cases, it is useful to re-seal the load-bearing beams in the walls or technological joints. For example, you can install damper pads and inserts from a porous incompressible material.
Choice of sound-absorbing material
In ordinary cases, getting rid of the noise of neighbors from above helps to install slab or roll materials, scattering vibrations of the air until the formation of white noise with an acceptable intensity. In this case, both special composite materials and conventional heaters such as mineral wool are used.
Soundproofing the ceiling with mineral wool
The advantages of special materials include their high efficiency, the disadvantages are their equally high cost. The best way damping of air vibrations occurs at the boundary of two dissimilar media, for example, cardboard and mineral wool. A secondary role is played by the shape and size of the cells, the density of the materials and the order in which the layers are applied.
All of these principles can be applied to self-manufacturing soundproofing cake. However, one should avoid the advice of amateurs and understand that materials such as polyurethane foam, XPS, egg trays, cork and other "innovative" noise absorbers do not have any positive effect, and in some cases even aggravate the situation.
Felt, mineral wool with a density of 40–60 kg/m3, acoustic mineral wool, wool and coconut fiber can be considered the most suitable. From specialized materials Tecsound roll and AcousticWool mats can be cited as the most effective for soundproofing ceilings.
Features of installation of sound insulation
By soundproofing the ceiling when finishing it with a stretch fabric, you avoid the need to install a frame suspension system that prevents the spread of structural noise. All that is needed is to fix one or more layers of sound-absorbing material on the draft plane.
Separation must first be made air environments, since the direct transmission of airborne noise is most intense. In the general case, pasting the ceiling with cellophane helps, but such actions require caution so as not to disturb the climate in the room. If the ventilation and insulation system requires free gas exchange through the interfloor ceiling, it is necessary to use vapor-permeable membranes.
In general, sound insulation is fixed to the ceiling by means of plate-shaped dowels used in the system. wet facade. Their length and installation step depend on the thickness of the material, its density and ability to retain its shape. It is most difficult to mount multilayer insulation, where temporary fixation of superimposed layers is required. For these purposes, you can use spot gluing or a structure that supports the cake until it is finally fixed.
In one of the most effective noise absorption pies, a concrete ceiling is covered with two layers of corrugated cardboard on silicate glue, then ceiling profile a temporary support system is being assembled for the GKL. Acoustic wool is laid in rows on the slats in mats of 60-70 mm, a felt carpet about 10 mm thick is covered under it. The denser material in the bottom layer allows better sound absorption and fewer fasteners.
Interfacing with soundproofing walls
When installing the soundproofing of the ceiling, it is important not only to tightly join the elements of the insulator itself, but also to achieve minimal interaction with the soundproofing of the walls. A stretch ceiling allows you to build false wall cladding not under the ceiling itself, and you need to use this advantage.
To be sure that there will be no space left in the corner junction of the wall to the ceiling for the free propagation of airborne noise, the edges of the ceiling sound insulation must be wrapped and brought into a hidden plane just below the level of the tension coating.
If there is a filler behind the false wall that contributes to the absorption of sounds, you should make sure that its upper open edge is even and the ceiling insulator will fit snugly against the wall insulator. Special fastening in this place is not required, it is only necessary to achieve tight laying without air gaps and make sure that the rigid surface of the skin is at some distance from the horizontally located insulation layer, that is, it does not rest against it. published
Noise from upstairs neighbors often annoys residents of apartment buildings. Sounds from the TV or music center, loud speech and clatter interfere with normal rest and poison life. It’s good if excessively active neighbors soundproof the floor - this method is most effective for eliminating interfloor noise. But more often you have to solve this problem yourself with the help of soundproofing ceilings.
Types of noise and methods of their distribution
Noises that annoy neighbors can be divided into two types, the preferred type of soundproofing material depends on their variety.
Distinguish noise:
- air, these include speech, sounds from audio equipment, musical instruments; such noises propagate mainly through the air and are clearly audible through thin and porous partitions and ceilings;
- structural, or shock - they occur when walking, falling objects, moving furniture, as well as during the operation of vibrating household devices, such as a refrigerator; such noises propagate through solid materials, and the intensity of their propagation is 12 times higher than air.
The level of airborne noise is regulated by SanPiN 2.1.2.2645-10 "Sanitary and epidemiological requirements for living conditions in residential buildings and premises" and is 40 dB during the day and 30 dB at night. Neighbors who turn on loud music at night can be curbed with the help of the police. Structural noises are periodic in nature, so it is difficult to measure and prove their excess level. The only way avoid them - soundproofing the room.

Since structural noise is transmitted through all building structures, soundproofing the ceiling may not be sufficient and the walls will also have to be insulated. However, installing a soundproofing layer on the ceiling significantly reduces the penetration of extraneous annoying sounds.
What is stretch ceiling soundproofing for?
It is believed that stretch ceilings in themselves are a sound barrier that significantly reduces noise. But, as practice shows, this is not always the case. Under certain conditions stretch ceiling can play the role of a speaker, which will repeatedly amplify the vibrations of the floors, as a result, the sounds coming from the neighbors from above will be transmitted downward with amplification.
This situation is possible in several cases:
- with a significant amount of cracks, crevices and gaps in interfloor ceilings through which airborne noise penetrates - music, speech;
- at a distance from the base ceiling to the stretch ceiling more than 5 cm, which is possible in case of large unevenness of the floors;
- when fastening structures not to walls, but to the ceiling, for example, in combined multi-level ceilings; in this case, the fasteners play the role of sound bridges, through which vibrations and shock noises are transmitted.
In order to get rid of noise for sure, it is better to soundproof it with modern materials even at the stage of preparing the ceiling for finishing.
Stretch ceilings do not always cope with sound insulation
Types of ceiling soundproofing
For effective soundproofing of the ceiling, materials that can absorb all types of noise are suitable. According to the degree of rigidity, they are divided into several groups.
- Solid- based on pressed mineral wool with the inclusion of natural porous materials such as perlite or vermiculite.
- semi-rigid- plates with a fibrous cellular structure based on mineral and basalt wool.
- Soft- fiberglass, mineral or basalt wool in the form of rolls, two or three layers, covered with a material that facilitates installation and prevents dusting of the fibers.
Table number 1. Comparative characteristics these materials.
As can be seen from the table, with decreasing density, the sound absorption coefficient increases. It is important to know that low-density materials are more difficult to mount: solid soundproof materials can be attached to glue, semi-rigid ones will require installation of a frame or fastening to special dowels, while soft materials must be pulled to the ceiling with twine.
When choosing a material, one more feature should be taken into account: the higher the density of the material, the better it absorbs low frequencies - the sound from a working refrigerator, subwoofer. The sound absorption of high-frequency and mid-frequency noises, which include speech, singing and music, on the contrary, worsens.
It is worth analyzing which sounds annoy you the most, and choose the density of the material based on this.
The most popular soundproofing materials
To facilitate the choice of material, you need to compare the characteristics of sound insulators that have proven themselves in the construction market.
Table number 2. The most popular materials and their description.
| Name | Type and purpose | Sound absorption | Thickness, mm |
|---|---|---|---|
| Universal rolled composite material for airborne and impact sound protection. Ceramic fiber coated with spunbond on both sides. | Up to 65 dB | 12 |
| Basalt fibre. From all kinds of noise. | Coefficient: 0.92 for 50 mm 0.95 for 100 mm | 50 or 100 |
| Rolled composite material, needle-punched fiberglass covered with spandbond on both sides. From all kinds of noise. | 28-33 dB Coefficient - up to 0.87 | 10, 12 or 14 |
| Slab sound insulator based on basalt wool. | Coefficient - 0.8 | 50 |
| Rubbery membrane material based on argonite, one side covered with spandbond, minimum thickness. | 28 dB | 3,7 |
What materials should not be used
Soundproofing ceilings has its own characteristics, because of this, the use of certain materials can be useless, and sometimes harmful.
- Styrofoam and expanded polystyrene. These popular and easy-to-use materials with good thermal insulation properties are completely unsuitable for soundproofing ceilings. They have a porous windproof structure, due to which sound damping does not occur, and in some cases it even intensifies. Expanded polystyrene can be used as a sound insulator only when installing floors to protect against impact sounds.
- Cork. This material is good in soundproofing floors and as a substrate for floor finishes, but it will be almost useless for dampening noise from neighbors from above.
- Rolled mineral wool without low density coating. The soundproofing properties of this material are not bad, but mounting it on the ceiling is inconvenient: for good soundproofing, it is necessary to ensure a snug fit of the acoustic material to the base ceiling and a gap of about 20 mm to the stretch ceiling. Loose material will sag, you will have to fasten it to special dowels, located quite often. As a result, many sound bridges are formed that perfectly conduct impact noise, which will make sound insulation ineffective.
Calculation of the required amount of materials
The required amount of soundproofing material is calculated according to the area of the room. It must be divided by the area of the insulated surface indicated on the packaging of the material, and the result should be rounded up.
For example, if the area of the room is 20 m² and the area of the insulating mats per pack is 7.2 m², then you will need 20/7.2= 2.77 packs. After rounding up to a whole number, 3 packs of material will come out.
It is convenient to do the calculation on a sheet of paper with a scaled plan of the premises - it is easier to draw the layout of the material and avoid unnecessary trimmings and joints of the insulation. It should be remembered that each gap increases the sound transmission.
For the best effect, the insulation is placed in two, and sometimes three layers with offset seams, so that the second row completely overlaps the joints of the first. In this, the amount of material obtained must be multiplied by the number of layers.
Preparing the ceiling for soundproofing
Before proceeding with soundproofing work, it is necessary to prepare the ceiling, which will help to avoid peeling of the soundproofing boards. Do it in the following sequence:
After preparing the ceiling, you can proceed with the installation of sound insulation using one of the following technologies.
Installation of thin composite sound insulation on glue
The method is suitable for fastening sound insulation such as Maxforte Standard, Termozvukoizol, Texound 70, as well as for board materials based on low-density basalt.
Pros of the method:
- high installation speed;
- reliability.
- additional costs for glue;
- toxicity.
Required materials and tools:
- aerosol glue in a can;
- knife for cutting material;
- roulette.
Mounting technology
Important! When working, it is advisable to use a respirator and regularly ventilate the room.
Installation of slab semi-rigid sound insulation on glue
This method is suitable for soundproofing board materials such as Maxforte EcoPlite and Shumanet BM, with a density of at least 30 kg/m³.
Pros of the method:
- saving time - no need to mount the crate;
- minimum gaps and sound-conducting elements;
- ease of installation.
- extra costs for glue and dowels.
Necessary tools and materials:
- glue on a cement or gypsum basis;
- spatula for applying glue;
- sharp knife for cutting plates;
- roulette;
- drill or perforator;
- special plastic dowels of the "fungus" type at the rate of 5 pieces for each plate.
Mounting technology
- Prepare the ceiling according to the above technology. Wait for the primer to dry completely.
- Mix the required amount of glue according to the instructions on the package.
- Apply glue to the plate over the entire surface in a thin and even layer with a spatula.
- The laying of the plates begins from one of the walls, tightly fitting them to each other.
- Additionally, the plates are fixed with the help of dowels "fungus". To do this, holes are drilled directly through the glued plates with a depth of 50-60 mm more than the thickness of the insulation. Dowels are hammered into them, 5 pieces per plate - in the corners and in the center. The dowel cap should firmly press the plate.
- Wait for the glue to dry and proceed with the installation of the stretch ceiling.
Important! If it is planned to install a stretch ceiling made of perforated acoustic fabric, it is necessary to insulate the slabs with a vapor barrier film and only then fix them with dowels. Otherwise, over time, basalt fibers will begin to penetrate into the room, which is unfavorable for health.
Installation of soundproofing on the frame
This method is suitable for slab or roll materials based on basalt and mineral wool or fiberglass of any thickness, including multilayer construction.
Example of installation of sound insulation on a metal frame using a membrane "100 dB Lux"
An example of mounting sound insulation on a metal frame using a matte insulator "ThermoZvukoIzol"
Pros of the method:
- no need to drill the ceiling for fungal dowels - the material is placed by surprise and held tight;
- You can build a structure of any thickness.
- extra time and money spent on the construction of the frame.
Required materials and tools:
- guides for the frame of a wooden block or galvanized metal profile;
- damper tape made of foamed polyethylene for damping impact noise;
- drill or puncher and dowels for attaching the frame;
- scissors for metal or a jigsaw for cutting frame material;
- knife for cutting insulation;
- tape measure, marker.
Mounting technology
Important! For multilayer sound insulation, the frame can be made as follows: fix the first row of guides along the room, the second - across, on top of the first layer of sound insulation laid. This will completely cover the gaps and create additional acoustic decoupling.
Installation of sound insulation with low density
When using mats or rolls based on low density mineral wool, sagging of the material can be encountered. It is solved by fixing soundproof mats with dowels and twine.
Mounting technology
- On the prepared ceiling, a frame from a bar is mounted in the manner indicated above.
- Soundproof mats or rolls are placed between the frame bars.
- A vapor barrier film is laid on top of the soundproofing layer, fixing it on the frame bars using a construction stapler.
- Additionally, the structure is fixed with dowels at the rate of 5-6 pieces per square meter of the ceiling.
- To avoid caking and sagging of mineral wool, a cord or twine is pulled between the dowels, creating a lattice or mesh over the entire surface of the ceiling.
Important! The cord or twine should not stretch, so it is better to choose nylon or other synthetic material.
After completing the soundproofing work, you can proceed with the installation of a stretch ceiling made of fabric or PVC film. You can do this on your own or with the involvement of specialists. At the same time, a gap between the sound insulation layer and the stretch ceiling should be at least 2 cm.
For the best protection against noise, you can additionally use modern fabric-based acoustic materials for the installation of a stretch ceiling. The basis of such a fabric is a polyester mesh, at the first stage of production it is poured with polyurethane, and after the formation of a film, microscopic holes are made in it.
Passing through the holes, the sound changes its frequency and intensity to values that are not perceived by the human ear, and is partially absorbed. The cost of such a film is somewhat higher than conventional materials for stretch ceilings, but their soundproofing properties are much better.
The most famous manufacturers of acoustic stretch ceilings are Clipso and Cerutti. In addition to eliminating sounds coming from the ceiling, they also dampen sound vibrations from equipment located inside the room, which will allow you not to disturb your neighbors at a later time.
Properly performed sound insulation does not lose its effectiveness for a long time, and does not require repair or replacement throughout the life of the stretch ceiling. Installation of sound insulation under a stretch ceiling will allow you to enjoy peace and quiet at any time of the day and find the long-awaited comfort.
