Glue sound insulation to the ceiling. Soundproofing the ceiling - how to make soundproofing

When it comes to soundproofing the ceiling, the first thing you think about is getting best results for their money.

But for this you need to know the basic soundproofing principles, methods and understanding of sound processes, which are the subject of a section of physics - acoustics. There are many soundproofing technologies and materials available, but only a few will be suitable for a given situation.

If you are planning to soundproof the ceiling with your own hands, then find solutions that will be inexpensive and easy to install soundproofing of the ceiling. The more knowledge you have, the more consciously you approach the question of how to soundproof a ceiling, the better the end result will be.

Ceiling soundproofing is based on selection sound-absorbing materials And technical solutions at the installation site in order to achieve a reduction in noise of impact, air, and structural origin.

What is the difference between sound and noise? Sound, as is known from physics, is mechanical vibrations molecules of a substance under the influence of forces capable of creating changes in the position of the molecules of a substance in one place and transmitting this effect to neighboring molecules. This creates a sound wave that is perceived by the human auditory organs.

A sound wave is characterized by amplitude, frequency, phase, and speed of propagation. It is characteristic that the speed is almost independent of the frequency of the wave. Therefore, the human ear perceives sounds in the same order in which they are reproduced by the sound source. Otherwise it would be difficult to discern what was coming from the loudspeaker.

There is another effect of sound force on the hearing organs, when the threshold for the perception of sound frequencies in the range of 16-20000 Hz is exceeded, but the force of pressure on the eardrum depends on the volume level, measured in dB (decibels).

A value of 0 dB corresponds to a pressure of 20 microPascal, which determines the lower threshold of audibility, and 120 dB is the upper threshold, the short-term impact of which is painless. Prolonged exposure to 80 dB will cause hearing loss.

Loud sound protection is performed soundproofing materials for the ceiling. They absorb the wave, converting vibration energy into heat. The sound dissipates and the intensity of the impact decreases. The phenomenon of refraction is taken into account in the manufacture of the material. It is known that when a sound wave passes from one medium to another, the following phenomena occur:

More often these phenomena occur simultaneously. Diffraction phenomenon– the ability of a sound wave to bend around obstacles. The size of the wavelength is compared with the size of the obstacle: if the wave is smaller, then it is reflected, and if, on the contrary, or comparable to the size of the obstacle, then the sound wave is diaphragmed. If, for example, this is a gap, then the wave goes around it too. Resonance and interference are also taken into account in the design of soundproofing systems.

Phenomenon reverberation occurs in a confined space. Sound vibrations are repeatedly reflected from walls, ceilings, floors, and other objects. The final perception is distorted, causing discomfort. This is noise.

The concept is rather subjective, not amenable to strict assessment. Concept of the term "soundproofing" used for indoors, and for cars they use the term "soundproofing". Note that the noise created by undefined sounds does not have to be loud. A quiet snoring coming from the next room is enough to cause insomnia.

Street noise during the daytime is not as perceived as if it occurred at night. For some, noise does not cause discomfort, while for others it interferes with any activity. Levels sound pressure on the eardrum are most severe during low-frequency vibrations. It's determined Sanitary Standards SN 2.2.4/2.1.8.562-96. Table 3.

Soundproofing materials for ceilings

Purpose of soundproofing ceilings- prevent sound penetration from outside, absorb sound waves generated by sound sources indoors.

It is logical to assume that an effective way to protect against these phenomena would be to limit the influence of sources of sound creation, which is not always possible to do, because not every neighbor can be agreed upon, and street noise cannot be controlled. So we have to look for soundproofing material for the ceiling.

Protection against reverberations comes down to the proper placement of sound-absorbing materials for the ceiling, walls, as well as the use of interior materials:

  • curtains on the windows;
  • cushioned furniture;
  • bookshelves;
  • acoustic screens;
  • carpets on the floor.

Among modern soundproofing materials for ceilings, the following can be distinguished:

  1. MaxForte SoundPro is a new generation of roll sound insulation. Created taking into account theoretical developments in the field of building acoustics. With a thickness of 12 mm, it provides effective protection against impact and airborne noise. Maximum class “A” for sound absorption. Ideal for small apartments where every centimeter counts. No glue or chemicals included. The material is completely non-flammable.

    Suitable for soundproofing ceilings, walls and floors. Can be used in framed and frameless schemes. Rolls are not afraid of moisture and do not attract insects and rodents.

  2. MaxForte EcoPlate - basalt slabs made of volcanic rock, have excellent acoustic properties. Without smell. The material contains no impurities of slag and blast furnace waste.

    It is used for sound insulation in the most complex facilities: cinemas, recording studios, restaurants. High ratio sound absorption αW at all frequencies (including low). Completely non-flammable material.

  3. MaxForte EcoAcoustic – polyester boards (acoustic synthetic padding). To maximize sound absorption, aerodynamic fiber laying is used during production. The material is made from homogeneous raw materials, does not emit harmful substances, and does not contain glue.

    During installation they do not crumble, do not generate dust and do not prick. Working with the material does not require special clothing, gloves or a respirator. Suitable for allergy sufferers and asthmatics. Not afraid of moisture.

  4. Vibration Stop Pro – vibration isolating mount to eliminate impact noise. Allows you to reduce vibrations transmitted to the profile and provide additional sound insulation of the ceiling and walls at a level of 21 dB.

  5. MaxForte sealant - used for sealing seams, joints and holes. Does not allow sound or vibration to pass through. High waterproofing properties. Contains fungus and mold inhibitors. High adhesion to all types of surfaces.

Also, effective sound insulation of the ceiling is performed by acoustic panels. Let's start our selection with them.

Acoustic panels - soundproofing material for ceilings

CFAB™ Cellulose Panels– panels based cellulose. Made from 65-75% recycled materials, an alternative to traditional synthetic fiberglass panels. Some panels from foreign manufacturers have a density expressed in 1 lb/ft3 = lb/ft3. Which, translated into standard units, will be 16.02 kg/m3.

If you see the panel density indicated in lb, then most likely these panels are from a foreign manufacturer. Here is a brief description of CFAB™ Cellulose Panels:

The sound absorption coefficient is characterized by a value from 0 to 1. Moreover, the lower the value, the higher the reflectivity. A value of 0 is total reflection of the sound wave, and 1 is complete absorption. Coefficient of 0.4 and higher for sound-absorbing materials. They are used to protect against airborne noise (which is transmitted through the air). In addition to the sound absorption coefficient, there is a characteristic sound insulation index (RW), expressed in dB, which is used for structures (prefabricated systems).

What density of mineral wool to use for soundproofing the ceiling depends on nature of the noise: if it is airborne noise, then a density of 70 kg/m3 and an absorption coefficient of 0.7-0.8 are sufficient; at a noise level of 25 dB a person feels comfortable. This applies to soft materials such as the CFAB™ acoustic panel. With a thickness of 50 mm and a density of 48 kg/m3, the sound absorption coefficient reaches 0.9.

If you need to improve the acoustics in a home theater room, then choose a soundproofing material for the ceiling taking into account the interior. Perhaps several absorbing screens installed around the perimeter of the walls and on the ceiling will be enough. Apply CFAB™ or Echo Eliminator™ directly to a wall or ceiling.

See the picture for how to soundproof the ceiling and walls using a frameless method.

What materials and tools will you need for frameless soundproofing of the ceiling with your own hands? If the ceiling is concrete, then the ceiling soundproofing device is performed gluing acoustic panels. You will need: a metal scraper or brush, primer, putty, glue, measuring and cutting tools, Remedies.

The order of work is as follows:

  1. Preparing the ceiling. Remove with a scraper or brush old cladding in places where it does not hold well. Then all the cracks and cracks are puttied, allowed to dry, then a primer is applied to the ceiling.
  2. Gluing panels. Mark the boundaries of the panel on the ceiling or wall, then back side The panels are sealed with “liquid nails” and additionally smeared with glue. Press the panel against the ceiling or wall and hold for 5-10 seconds.

Advice. To rationally use the material, before soundproofing the ceiling, estimate how many whole panels you will need. Gaps are left between the wall and the ceiling, so start gluing along the middle axis of the ceiling, this will maintain symmetry.

Installation of ceiling sound insulation frameless way They are made as an addition to an already finished gypsum ceiling or to a pre-prepared and leveled concrete ceiling.

It is more difficult to achieve maximum sound insulation of the ceiling and walls from structural And impact noise. Structural noise is formed in sewer and water pipes, but this problem has already been practically solved in modern construction: plastic pipes successfully act as a damper on the path of sound waves.

As for impact noise transmitted through blocking structures, everything is much more complicated here. We need to solve the problem comprehensively. The best soundproofing of the ceiling from such sounds is suspended ceiling systems: slatted ceilings, plasterboard ceilings, stretch ceiling.

Suspension systems - the best sound insulation of the ceiling

There are suspension systems that differ in the method of attaching the frame and the types of suspensions (clips).

Consider a universal hanging system that is suitable for ceilings and walls.

Attention! The gypsum board wall and ceiling panels are separated by damper clips from the ceiling and wall.

I wonder how it affects suspended ceiling for sound insulation with such a suspension system?

If you pull it in addition to this system, then more two layers of media of different densities: canvas and air gap between ceilings. A sound wave, passing through an additional structure, will be refracted in 2 media and give each of them its energy. A suspended ceiling takes away 80-100mm of the ceiling height. You can assemble a structure from gypsum plasterboard using special ceiling hangers for wooden beam 50 x 50 mm.

Do-it-yourself ceiling soundproofing

This is the kind of hanger you need for assembly.

Installation of ceiling soundproofing begins with markings. Here is an approximate diagram of how the hangers and bars of the first row of gypsum boards should be positioned.

First, the lathing is made, then a 19mm gypsum board is sewn to it, mineral wool is laid, and then a second insulating layer of gypsum board with a thickness of 12.5mm is hemmed to the gypsum board. This is what such a pie will look like.

Here's the height additional design will be 75 mm. Sound insulation on the ceiling (1), made with mineral wool (4), is in a multilayer structure and protects against all types of noise: airborne, impact, structural.

If in this design, instead of gypsum board (1), there was a stretch ceiling sheet, then attaching sound insulation to the ceiling (6) would complicate the work: sheets of mineral wool would have to be glued to the old ceiling before installing the ceiling, but after installing the stretch ceiling, finishing would not be needed.

Source of noise in the bathroom most often are the sounds of working washing machine, the noise of water falling on the shower tray, the operation of the exhaust fan,

Soundproofing the ceiling in the bathroom will partially solve this problem. Can be pasted on the ceiling sound-absorbing material, cover it from below with a suspended ceiling - the problem of airborne noise will be solved. Eliminate vibration of the washing machine using spacers for the supports. Choose a fan with low noise level.

Thin ceiling sound insulation involves the use of soundproofing materials as damping pads. These materials provide excellent protection against vibration sounds and are used for soundproofing cars.

When choosing a particular material for sound insulation, be guided first of all effectiveness of problem solving. Airborne noise insulation is achieved using soft, thick materials with a porous structure. Impact noises are isolated fibrous materials high density.

If it is difficult to choose what kind of sound insulation you need, consult with sales department consultants and other specialists. Unfortunately, you can only fully check whether soundproofing the ceiling helps, and also find out what the effectiveness of the soundproofing material is by installing it. Testing of the material by the seller in the presence of the buyer is not always as effective as after final installation on site.

Remember, the ceiling soundproofing device is effective even with noise reduction by 5-10 dB is a good result, reducing the level of impact on the hearing aid by almost 2 times. In Table 3, the average daytime equivalent noise indicator is determined to be 40 dB, and the nighttime equivalent value is 30 dB. This is what we should strive for.

Good sound insulation means silence and a relaxing time in the apartment. Various types of insulation aimed at reducing the noise level in the room help to achieve such conditions. To find out what materials for ceiling soundproofing are used in modern construction, let's look at the most popular ones today.

When choosing materials for sound insulation, it is necessary to take into account their effectiveness. This is due to the types of noise that will have to be absorbed. All noise that occurs is divided into two types:

  • airborne noise is formed from air vibrations created by the mechanical action of some objects, for example, a closing door. They penetrate into the room through cracks and even sockets;
  • shocks are formed from mechanical impacts on the ceiling. A strong stomp of feet spreads across the ceiling of the lower apartment. But with poor sound insulation, it can be heard in the apartment located on the floor above.

The maximum level of silence can be achieved by soundproofing not only the ceiling, but also the walls together with the floor.

Designs for ceiling sound insulation

To lay materials for soundproofing the ceiling, you can make additional structures:

  • mount a suspended ceiling on a metal frame. It is attached to the floor slabs with hangers;
  • install a suspended ceiling, which is fixed with special brackets around the perimeter of the room. Modern manufacturers offer a huge selection of fabric-based or PVC stretch fabrics;
  • You can make a hemming structure from any sheet material, fixed to a metal frame on the ceiling.

When making any of the structures, it is necessary to leave a gap between it and the floor slabs for laying soundproofing material.

Arrangement of sound insulation without making a frame

By doing the soundproofing of the ceiling in your apartment yourself, you can avoid the labor-intensive and costly process of making a frame. This method is suitable for laying sound insulation under a suspended ceiling. There are two ways to do this:

Separation of soundproofing material by type

The structure of each material has its own characteristics, which determine the percentage of noise elimination in the apartment. Properly selected material can provide 99% silence protection. To understand the structure of the entire noise protection system, you need to know that according to functionality, materials are divided into two types:

  • structure sound-absorbing material It is based on a soft, porous or fibrous filler. A sound wave passing through a material is first slowed down and then completely absorbed. Such materials include slabs based on felt, basalt and padding polyester, mineral wool;
  • soundproof. Its functionality is exactly the opposite of the type considered. The dense and strong structure does not absorb sound, but reflects it away from itself. Such materials are concrete, brick and other analogues.

The best noise protection effect is achieved by joint application both types of material. It is a kind of sandwich construction with two outer layers of sound insulation and one inner layer sound absorption.

Types of materials

Good sound insulation of an apartment, made by yourself, depends on the thickness and quality of the material used. Today, the consumer is offered a huge selection of well-known products and new products, for example, membranes, cork and others.

Basalt wool

Basalt wool has a high degree of sound absorption due to the fact that it has a special sound absorption structure that differs from basalt insulation panels. Materials with such a base include slabs different manufacturers, for example, “Shumanet BM” or “Acoustic Butts”. The slabs are resistant to fire and rot. Their disadvantage is the release of small particles and an unpleasant odor of the chemical. But this problem is easily solved with the installation of additional sealing. The effectiveness of sound absorption by basalt wool is observed when using slabs with a thickness of 50 mm.

"Zvukanet Universal"

This type of insulation is made from fiberglass. The fourteen-millimeter filler is enclosed in a protective shell - a polypropylene membrane. Once installed, the insulation does not require sealing, which reduces the complexity of DIY work and is cost-effective.

Minvata

Probably the first and most common material can be considered mineral wool. In addition to noise absorption, it reduces heat loss, is easy to install, and has a lower cost compared to other modern insulation. Mineral wool is available to consumers in the form of a mat or roll.

To install it, you will need to construct it on the ceiling with your own hands. wooden frame. Its slats should have a smaller pitch so that the cotton wool fits tightly under them. For reliability, mineral wool is nailed down with nails or plastic umbrella dowels.

The disadvantage of mineral wool is its instability to dampness. To prevent it from swelling from moisture, waterproofing is laid underneath it and covered with a vapor barrier film on top. This is especially important in apartment rooms such as the bathroom and kitchen.

Traditional polystyrene foam

A slightly outdated, but not inferior in popularity, material is polystyrene foam. He is also excellent insulation. And although it cannot be classified as an environmentally friendly raw material, moreover, it is fire hazardous and releases toxic substances when burned, expanded polystyrene is in demand. This is due to its low vapor permeability and ease of installation with your own hands without outside help.

Its structure consists of balls increased in volume due to gas saturation, which gives them greater elasticity. The slabs are produced in thicknesses from 20 to 100 mm. Their noise absorption level is 23–25 dB.

During installation, the slabs are fixed to the ceiling polyurethane foam or liquid nails. For reliability, plastic umbrella dowels are used.

Wood based insulation

Environmentally friendly Izoplat and Isotex boards are made from wood fiber without the addition of fastening adhesives. Coniferous wood is used in their production. The slab thickness of 125 mm reduces sound transmission by 23 dB, and the decorative surface is available in four colors. Its edges have a tongue-and-groove connection, which allows you to create a seamless installation with your own hands. The slabs are fixed to the ceiling with glue or nailed with staples onto a wooden frame.

What is the Isotex ceiling panel made of?

Natural cork, due to its porous structure, reduces noise penetration at low thickness. The slabs are environmentally friendly, light in weight, but highly expensive. To protect your apartment from noise penetration, cork slabs are glued to a plasterboard sheet, after which this sandwich is attached to a frame for a false ceiling with the insulation inside. If the cork is simply glued to ceiling slabs ceiling, then it will protect the apartment located on the floor above. This is the peculiarity of the cork slab.

Soft fiberboard boards, for example, “Softboard” is made from wood waste without synthetic additives. The wood is split into fibers and dumped as wool. Finished slabs 8-20 mm thick are fixed to the ceiling with plastic umbrella dowels.

Ecowool is an affordable insulator. Although it is made from recycled paper, the material is resistant to rotting and damage by rodents. Ecowool is used when installing a false ceiling, simply pouring it onto plasterboard up to 70 mm thick.

Natural fiber insulation

Toward natural and environmentally friendly clean materials include slabs made from felt, coconut and flax fiber. Insulation is recommended for use in children's, medical and residential premises.

Eco-friendly insulation and insulation Coconut, fire safety class G3-G4

Membranes

IN Lately membranes are gaining popularity. Small thickness PVC sheets 3 mm can reduce the noise level by 26 dB. It can be used as the main insulator when installing a false ceiling or as protective layer basalt insulator. Installation is easy to do yourself. The only negative is the heavy weight, so you will need 2-3 people to work.

Ceiling soundproofing membrane

Liquid insulation

Easy-to-use liquid insulation is packaged in special containers, from which it is applied to the ceiling with a mounting gun. A good sound insulation effect is obtained by installing a two-layer false ceiling. Liquid insulation is applied between two sheets of drywall, screwing the resulting pie with self-tapping screws to the frame.

Modern environmentally friendly insulation

Finally, I would like to pay attention to two more environmentally friendly and modern materials:


Having considered many types of soundproofing materials, I would like to add that this list may be far from complete, since progress does not stand still, and new types of insulation will appear over time.

In contact with

To soundproof the ceiling in an apartment, two design options are currently used - frame and frameless suspended ceiling systems.

Note also that there is a third, often most good option sound insulation of the ceiling in the apartment, - insulation of the floor of the neighbor above. Unfortunately, this option is most often not applicable for objective reasons. At the same time, it is worth recognizing that it is significantly cheaper, and is also much more effective in protecting against impact noise. Therefore, if your upstairs neighbor is ready to meet you and the current SNiP “Noise Protection” halfway, we recommend solving the problem on his part.

Frameless ceiling sound insulation systems

The most famous frameless ceiling sound insulation system among modern materials for ceiling sound insulation on the Russian market is called ZIPS and stands for Sound Insulating Panel System. The soundproofing structure in this case consists of a ZIPS sandwich panel, which has eight vibration-isolating fastening units, and a finishing sheet of weighted plasterboard AKU-Line. The sandwich panel without gaps is mounted directly to the ceiling through vibration units using special fasteners, and the drywall is screwed to the panel. The panels are joined together using the tongue-and-groove principle.

Depending on the thickness of the system (from 53 to 133 mm), the indices of additional airborne noise insulation are 9-18 dB for floors with an initial sound insulation of 50 dB. Note! Indicating the type of floor for which the additional airborne noise insulation values ​​were obtained is extremely important, since various manufacturers talk about the “achievements” of their designs on load-bearing structures with their own noise insulation of less than 40 dB, where it is much easier to add 15 dB, not to mention 10 dB. The main characteristics of ZIPS systems - thickness and efficiency are given in Table 1.

Table 1 Comparison of frameless soundproofing ceiling structures

*ΔRw - index of ADDITIONAL airborne noise insulation provided by the structure

Distinctive feature ZIPS is the complete readiness of this system for quick and high-quality installation: vibration-isolating fastening elements included in the design, a set of special fasteners for various types of floors and vibration-isolating gaskets. Therefore, the likelihood of errors when installing ZIPS systems is minimized. This good foundation to the use of ZIPS for those who care about the final result, namely, high level soundproofing the room. It is important that these systems have been produced for 17 years, and the total footage of insulated surfaces has already exceeded 2 million square meters. At the beginning of 2016, the manufacturer introduced the third generation ZIPS system - model ZIPS-III-Ultra. The design is only 55 mm thick, but provides up to 13 dB of additional airborne noise insulation.

Video about the soundproofing panel system ZIPS-III-Ultra:

IMPORTANT NOTE: Due to the high popularity of ZIPS in the market of modern noise reduction materials, currently a large number of different manufacturers produce and distribute their sandwich panels, which are very similar in appearance to ZIPS panels. Such products are made from combinations of various materials, but they lack the most important component for noise reduction - vibration-isolating fastening units. Only a design containing vibration units truly provides high acoustic characteristics of frameless systems with an additional level of noise reduction. In the absence of vibration-isolating fasteners, any sandwich system is not much different from the Soviet version of an additional level of noise reduction in the form of dry plaster on gypsum beacons, and its effect does not exceed 2 - 4 dB.

Frame soundproofing ceilings

Frame soundproofing systems traditionally consist of more elements than frameless ones. To obtain the declared acoustic effect, they must be installed correctly, which significantly increases labor costs and the impact of installation quality on the final result. However, these systems also have an undeniable advantage: such solutions are based on plasterboard technologies that are widely known to every builder and are essentially a kind of “tuning” of well-known modern designs suspended ceilings from gypsum plasterboard. Another important advantage of frame ceilings is the ability to simultaneously use them not only to reduce noise, but also to level the surface of ceilings.

The set of components that make up an effective soundproofing suspended ceiling in an apartment is a combination of both general construction and special sound-absorbing modern materials. So, in order:

Metal carcass. For the construction of frames of suspended soundproof ceilings, they are used metal profiles Ultra Steel from Gyproc. The profile elements are produced in Russia, and the choice of this manufacturer is due to the high quality of the products. The metal frame is a general construction element of a suspended ceiling and is also used for ordinary cladding, partitions and ceilings.

In addition to this Album, the values ​​of additional sound insulation and suspended ceiling structures, indicating their thicknesses, are given here in Table 2.

table 2 Comparison of modern frame ceiling soundproofing structures

*ΔRw - index of ADDITIONAL airborne noise insulation provided by the structure.

It should be noted that the effectiveness of both frame and frameless systems of additional sound insulation is indicated by a “plug” of two decibels. Thus, the manufacturer sets a certain margin of safety for the results of their use, since laboratory values ​​( upper value interval) are not always achievable at real objects even with full compliance with installation technology. This demonstrates Acoustic Group’s responsible approach to guaranteeing acoustic efficiency for its branded products.

Ecology of consumption. House: The “cardboardness” of many domestic buildings has long become the talk of the town. To prevent neighbors from above from bothering you with the details of their everyday life, it is recommended to arrange at least basic sound and noise insulation of the ceiling. And how to do this correctly for tension systems - we will tell you in today's instructions.

The “cardboard quality” of many domestic buildings has long been the talk of the town. To prevent neighbors from above from bothering you with the details of their everyday life, it is recommended to arrange at least basic sound and noise insulation of the ceiling. And how to do this correctly for tension systems - we will tell you in today's instructions.

Types of noise and methods for eliminating them

In the context of construction and renovation, noise is divided into two main categories: structural and airborne, the name corresponding to the path of its propagation. The sources of each type of noise also usually differ. Aerial - this is music, the human voice, sounds of animals and working household appliances. Such noise is neutralized by damping air vibrations in a layer of porous, easily compressible material.

Structural noise, otherwise called impact or structural noise, occurs when there is intense impact on various parts of the building structure. Examples of such noise include chatter from washing machine, the sound of heels, although the most notorious is still the noise from an impact drill or hammer drill. The spread of noise of a structural nature is eliminated with the help of damper inserts at the junctions of one part of the structure with another, for example, between the ceiling and the reinforced belt of the wall.

In addition, in fact, even structural noise is perceived by humans as airborne, that is, at some point the building transmits vibrations to the air. A secondary way of sound insulation can be to dampen this vibration over the entire area of ​​communication between the walls and ceilings and the space inside the apartment, however, this method is considered more expensive in terms of material consumption.

One must 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 arising inside the room. However, it is quite possible to bring the noise absorption of walls to the standards specified 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 suspended ceiling provide any advantages?

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 through the connection of the fastening profile to the walls.

The propagation of low-frequency structural noise through the ceiling is prevented by gluing damper tape under the mounting profile. If you don't do this, you can end up with some 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 air noise and structural vibration of the ceiling, the situation is somewhat worse: the tension canvas practically does not prevent their spread and even enhances it. At the same time, the plane of the rough ceiling remains completely free for installing any kind of sound insulation of any thickness.

Dependence on the type of building

Work to eliminate construction noise must be planned in accordance with the structure of the building. In frequent cases, the most attention is required to the junctions between walls and floors and the specifics of sealing joints and technological cavities. In some cases, you can even come to the conclusion that surface installation of sound insulation will not give the desired effect.

A classic example of this is a panel house with a single-layer ceiling hollow slabs. In such buildings, acoustic resonance often occurs due to the rigid connection of the slabs to wall panels. The optimal solution is not soundproofing the ceiling, but cooperation with neighbors above to install their floor using floating technology.

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-seat load-bearing beams in walls or technological seams. For example, you can install damper pads and inserts made of porous incompressible material.

Selection of sound-absorbing material

In ordinary cases, installing slab or roll materials, dissipating air vibrations to produce white noise with acceptable intensity. They are used as special composite materials, as well as conventional insulation materials such as mineral wool.

Ceiling soundproofing mineral wool

The advantages of special materials include their high efficiency, while the disadvantages include their equally high cost. The best 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 these principles can be used when making your own noise insulation cake. However, you should avoid the advice of amateurs and understand that materials such as polyurethane foam, EPS, egg trays, cork and other “innovative” noise absorbers do not have any positive effect, and in some cases even worsen the situation.

The most suitable are felt, mineral wool with a density of 40–60 kg/m3, acoustic mineral wool, wool and coconut fiber. Among specialized materials, rolled Tecsound 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 tension fabric, you avoid the need to install a frame suspension system that prevents the spread of structural noise. All that is necessary is to attach one or more layers of sound-absorbing material to the rough surface.

The separation of air media should first be ensured, since the direct transmission of airborne noise occurs most intensively. In general, covering 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 attached to the ceiling using disc dowels used in a wet façade system. Their length and installation pitch depend on the thickness of the material, its density and ability to retain its shape. It is most difficult to install multilayer insulation, where temporary fixation of the applied layers is required. For these purposes, you can use point 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 with silicate glue, then ceiling profile A temporary support system is being assembled for the gypsum board. Acoustic wool is laid in rows on the slats in mats of 60–70 mm each, and a felt carpet about 10 mm thick is placed under it. Denser material in the bottom layer allows for better noise absorption and the use of fewer fasteners.

Pairing with soundproofing walls

When installing ceiling sound insulation, it is important not only to tightly join the elements of the insulator itself, but also to achieve minimal interaction with the sound insulation of the walls. A suspended ceiling allows you to build false wall cladding not right up to the ceiling, and you need to take advantage of this advantage.

To be sure that at the corner junction of the wall and the ceiling there will be no space left 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 covering.

If there is a filler behind the false wall that helps absorb sound, you should make sure that its upper open edge is smooth and the ceiling insulator will fit snugly against the wall insulator. No special fastening is required in this place, you just need to achieve a tight laying without air gaps and make sure that the rigid surface of the sheathing is at some distance from the horizontally located insulation layer, that is, does not rest against it. published

The concept of modern housing includes an impeccable interior, fashionable and comfortable furniture, stylish decorative items, as well as a variety of high-tech equipment that makes life easier. However, despite the presence of all the listed signs, the comfort and coziness of the home environment is often disturbed by noise coming from neighbors. To eliminate it, it is enough to install a good soundproofing system.

Types of noise, options for eliminating it

Depending on the source of occurrence, all noise is divided into airborne and structural. In the first case, we are talking about sounds generated under the influence of sound waves in the air flow. This includes loud speech or music coming from the audio system and penetrating through the walls into adjacent rooms.

The source of structural noise is mechanical actions - impacts of falling objects, drilling of materials. The formation of a sound wave occurs directly on the ceiling, and the speed of its propagation is 12 times faster than that formed in air currents, which is why such noises are clearly audible.

There are two ways to protect a room from sounds penetrating from above:

  1. Providing complete sound insulation.

    This option involves not only soundproofing the ceiling in the apartment, but also the floor and walls. To achieve this, construction and repair work is carried out in full, which requires large material costs. In addition, the construction of the structure involves reducing the area of ​​the room, which is not provided for in small apartments.
  2. Installation of a stretch ceiling in combination with a soundproofing system.

    If extraneous noise is detected from neighboring apartments after the renovation is completed, it is recommended to carry out partial sound insulation, for example, install special slabs in the gap between the suspended and base ceilings, so they will fit perfectly.

When choosing optimal and reliable methods for protecting a room, it is recommended to take into account the features of the building as a whole, since each of them has its own characteristics. operational features and level of sound insulation.

Features of panel houses

When buying an apartment in panel house It’s better to immediately think about carrying out complete sound insulation. Explained this recommendation the fact that the massiveness of the walls and ceilings between floors is approximately the same, and in the event of an occurrence, the noise flow spreads throughout all the apartments of the riser. Installing insulation on the ceiling alone will not solve the problem, so it is better to combine the installation of a suspension system with additional sound insulation walls and floor, as shown in the photo.


Features of brick buildings

If the apartment is located in a thick-walled brick building, then partial sound insulation, for example, installing special materials on the ceiling, will be sufficient to eliminate excess noise.

Features of monolithic frame houses

Monolithic frame construction is characterized by the presence of heavy interfloor ceilings and light internal partitions, easily transmitting sound waves. In addition, the use of modern lightweight materials ( hollow brick, foam concrete) for the construction of external walls contributes to increased thermal insulation and noise transmission.

Regardless of the type, sound insulation for the ceiling in an apartment is the most important stage finishing, since its quality and competence determine the level of comfortable and relaxing rest for all residents. Today, with the help of modern materials and construction technologies, this problem is easily solved, despite the complexity and time of detection.


The most common methods of ceiling sound insulation include the installation of an acoustic suspended ceiling, as well as the installation of plasterboard sheets with embedded soundproofing boards of any of the following materials:

  • foam glass;
  • basalt wool;
  • reed slab;
  • fireclay;
  • peat insulation boards;
  • polyurethane foam blocks;
  • staple fiberglass;
  • linen tow in mats;
  • cork covering;
  • coconut fiber.

Reliable ceiling sound insulation is made from an additional ceiling system in the form of:

  1. suspended ceiling - slabs of the selected material are attached to a metal frame installed on top of the old ceiling;
  2. false ceiling - on top metal frame Drywall is screwed in.
  3. – a textile film covering is attached to the installed special brackets.


Regardless of how to soundproof the ceiling in an apartment, the essence remains the same: a special soundproofing fiber is laid between the installed structure and the base.

Creating sound insulation by increasing the sound absorption coefficient

When completed repair work, or if it is impossible to fulfill them as effective way, which reduces noise, there can be an acoustic stretch ceiling made of perforated fabric, which perfectly damps sound waves. An important condition for using such a design, which also acts as a limiting factor, is the height of the ceiling (in more detail: "").

With a structure thickness that successfully reduces noise of about 120-170 mm, the ceiling height should be at least 3 meters.

The design, which combines an acoustic suspended ceiling and sound-absorbing mineral wool, laid between the base and the ceiling, will provide impeccable insulation. The operation is presented as follows: noise penetrating into the room from outside through the floor and walls is absorbed by the ceiling layer. The level of effectiveness in reducing unwanted sounds directly depends on the echo of the room and the thickness of the acoustic ceiling structure.

Cork ceilings are in great demand among consumers. Similar natural materials for soundproofing the ceiling in an apartment are distinguished by special molecular structure and porosity of the structure.


Thanks to a large number modern equipment, technologies, environmentally friendly raw materials and a sound-absorbing system is created, which includes various sound-proofing components. For such installation work, experts recommend installing slabs that act as a complement to any ceiling system. Thanks to their special properties, they ensure not only the absorption of external sounds, but also those generated indoors.

Thus, it is possible to create high-quality sound insulation yourself; you just need to have an idea of ​​the degree of protection and the height of the ceilings.

What materials can be used for ceiling sound insulation?

In the modern market, soundproofing of the ceiling in an apartment is installed - materials for which are presented in a wide variety, without any particular problems. The availability of high-quality, varied design solutions will help in creating impeccable sound insulation in a room for any purpose. Let's look at the basic, most common materials.

For a complete understanding of the properties of materials, the concept of “decibel” should be defined. This is a relative value expressed as a percentage or multiple. Decibels measure the amount of sound pressure, which is equal to sound volume. If we convert dB into several times, then with an increase in the sound insulation of the ceiling surface by 1 dB, an improvement in sound insulation is observed by 1.25 times, at 3 dB - up to 2 times, 10 dB - up to 10 times.

Features of soundproofing material Isotex

Innovative soundproofing products from the Isotex company are aimed at creating effective soundproofing of a room with a minimal reduction in its area - 12-25 mm of the required height contributes to impeccable efficiency.


The 12 mm thick sound-absorbing ceiling panels provide sound insulation of 23 dB. The design is based on several heat and sound insulating Isotex boards, and the finishing coating is made of foil paper, which reduces the amount of heat loss from ceiling surface. Improved sound insulation properties are guaranteed by frameless Isotex panels, which are attached to the ceiling with liquid nails and are also assembled with a tongue-and-groove connection, which prevents the presence of gaps and cracks through which, as a rule, extraneous sounds penetrate.

Experts have proven the high practicality of these structures - with a significant increase in sound insulation of ceilings, only a small area is used than when working with frame systems.

Features of soundproofing material Isoplaat

Thermal and sound insulating boards Izoplat with a thickness of 25 mm in combination with a false, suspended or suspended ceiling provide reliable sound insulation for a room. The panels contain natural coniferous wood and are completely free of any synthetic or adhesive additives. The material does an excellent job of absorbing sound and is able to muffle impact and airborne noise coming from neighboring apartments. When using a slab from this manufacturer with a thickness of 12 mm, it is possible to increase noise insulation to 23 dB, and slabs with a thickness of 25 mm - up to 26 dB.

Soundproofing material is installed using glue without the requirement for pre-treatment and leveling of the ceiling surface, which significantly simplifies the process and reduces the cost of the work. A distinctive feature is the presence on one side of a rough, wavy layer, which allows the sound wave to be dispersed. The other side of the slab is smooth - it will need to be plastered, painted or covered with ceiling wallpaper.


Acoustic material“Zvukanet” for wallpaper is presented in the form of a soundproofing membrane, which will provide good sound insulation for the ceiling in the apartment and on the walls. The reduction in household noise reaches 21 dB. The system is covered on both sides with paper, on top of which wallpaper is glued. Available in 14 m rolls, 500 mm wide.

Green Glu is a high-quality vibration and sound insulation material, helps absorb vibration and sound waves, and can be used in combination with thin frame systems. During installation, it is laid as a layer between gypsum fiber boards or gypsum boards. One tube with a capacity of 828 ml is enough for 1.5 square meters.

Each layer has a certain thickness - 3 mm, 0.5 mm and 3 mm, respectively. Material dimensions – 3x1 m.


In short, domestic and foreign manufacturers provide a varied selection of materials manufactured according to the latest technologies taking into account the needs of the modern consumer. If desired, a combination of compatible insulation options is allowed. As an example, we can consider the possibility of creating a highly effective soundproofing system from a membrane that helps absorb sound waves, in combination with similar slabs.

Key points when creating ceiling soundproofing


The best is considered to be a frame sound-absorbing system made of plasterboard slabs using special membranes. Modern materials And reliable fastening will guarantee optimal design efficiency.

Ceiling sound insulation "Premium"

To build such a structure, plasterboard with a two-layer Texound 70 membrane and two-layer gypsum plasterboard is required.

Installation work is carried out in the following sequence:

  • ThermoZvukoIzol is applied to the pre-prepared ceiling;
  • the Texound-70 membrane is attached as the first layer using glue or dowels;
  • installation of direct hangers or hangers on rods is carried out;
  • a profile measuring 60x27 is fastened with subsequent inter-profile lathing. Heavy construction requires reliable fastenings and at least five hangers per square meter of material.
  • a noise-absorbing Rockwool mineral wool layer with a density of up to 60 kg per 1 m3 is placed in the inter-profile gap;
  • membrane material Texound-70 is glued on top of the profile on the front side (it is directed towards the wall surface);
  • The first sheet of gypsum board is attached to the profile, after which you can install a second sheet on top of it, as well as a second layer of membrane.


To achieve the greatest efficiency of Premium soundproofing material, it is enough to ensure air gap about 50-200 mm between mineral wool and Texaun-70 membrane. Depending on the thickness of this layer, the thickness of the entire structure is determined - 90-270 mm, so you should initially decide on the loss of area in favor of improving sound insulation.

The difference is this:

  • ThermoSoundIsolation layer with membrane material not attached to the floor slab;
  • the structure of direct hangers must be wrapped in Texound-70 membrane. The finished soundproofing system “Economy” will be no more than 66 mm thick.

What difficulties arise during installation work?

Soundproofing device, like any other type construction work, is accompanied by a number of inconveniences and difficulties:

  1. Laying and fastening of materials is carried out at height, so at least two workers are required, and for the convenience of their movement, scaffolding will be needed, which must either be rented or purchased.
  2. High-quality materials for sound insulation, offered by trusted manufacturers, will cost the same price as their subsequent decorative design.
  3. If the soundproofing structure is exposed to moisture, the risk of damage will increase. mineral wool slabs, which can be avoided by choosing expensive and moisture-resistant materials, such as cork panels.
