How to make soundproofing in an apartment under a stretch ceiling. Soundproofing the ceiling in the apartment - modern materials Cheap soundproofing of the ceiling

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 to avoid them is 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, a 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 sound insulation

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.

1. Solid- based on pressed mineral wool with the inclusion of natural porous materials such as perlite or vermiculite.
2. semi-rigid- plates with a fibrous cellular structure based on mineral and basalt wool.
3. 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 of 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 mounted on 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.

1. 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.
2. 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.
3. 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 floor plan depicted on a scale - 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

1. Prepare the ceiling according to the above technology. Wait for the primer to dry completely.
2. Mix the required amount of glue according to the instructions on the package.
3. Apply glue to the plate over the entire surface in a thin and even layer with a spatula.
4. The laying of the plates begins from one of the walls, tightly fitting them to each other.
5. 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.
6. 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 for a multilayer structure.

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 dowels-fungi - 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 bar 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 soundproofing 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

1. On the prepared ceiling, a frame from a bar is mounted in the manner indicated above.
2. Soundproof mats or rolls are placed between the frame bars.
3. A vapor barrier film is laid on top of the soundproofing layer, fixing it on the frame bars using a construction stapler.
4. Additionally, the structure is fixed with dowels at the rate of 5-6 pieces per square meter of the ceiling.
5. 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, the 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 entire 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.

Ways to soundproof the ceiling

There are several ways to install soundproofing on the ceiling. Basically, the choice depends on the stage of apartment renovation and financial capabilities. For example, if you have just started a major overhaul of a room, it will not be difficult to soundproof the ceiling by making a frame and installing plasterboard sheets on it. If the need for soundproofing arose after the repair was completed, then you can use the method of gluing plates or membranes to the ceiling in order to avoid the “dirty” installation stage.

Installation of soundproofing on the frame

Soundproofing the ceiling with a frame method is carried out at the very beginning of the repair. For fast and high-quality work, you will need the help of a partner. Installation of insulation is carried out as follows:

1. Remove the old coating from the ceiling (lime, emulsion, decorative tiles, etc.)
2. Seal all cracks between walls and floor slabs with cement mortar.
3. Treat the ceiling with adhesive.
4. Glue the soundproofing membrane over the entire surface of the ceiling.
5. Make markings on the ceiling for the frame guides. Place the guides at a distance of 30-40 centimeters from each other.
6. Based on the markings, install the hangers for the guides. Fix the hangers to the ceiling with dowel screws, having previously treated the screw and the junction with a vibration-isolating sealant.
7. Using screws, install the rails on the hangers. During installation, using a level, check the correct horizon of the guides.
8. Install on rails, fasteners for insulation. For the manufacture of fasteners, you can use a metal tape for suspensions.
9. Place the sound deadening material between the frame rails.
10. Install sheets of soundproof drywall or other finishing panels on the frame.
11. Seal the seams between the sheets and apply the finish coat.

During the installation of sound insulation, do not forget to timely bring all the wires for lighting to the right points and make holes for lamps or a chandelier.

Soundproofing ceiling without frame

Soundproofing the ceiling without making a frame is best done using ZIPS panels. This type of sound insulation is a sandwich panel consisting of a sound-absorbing layer, sheets of weighted drywall and vibration-isolating fasteners.
Installation of a soundproof panel system consists of the following steps:

1. Prepare the surface of the ceiling: remove the old coating, cover all cracks, even out uneven surfaces.
2. Along the perimeter of the ceiling, glue strips of insulation on the wall, with a width exceeding the thickness of the panel by 1-2 centimeters.
3. Start the installation from the corner of the room and with the help of a partner, attach the panel to the ceiling.
4. Through the holes in the panel, make markings for the screws of the fasteners.
5. Lay the panel down and drill holes in the ceiling for the fixing screws.
6. Mount the panel to the ceiling using special vibration-proof mounts supplied with the panels.
7. Thus, install the panels over the entire surface of the ceiling.
8. After installing all panels, do or .

In addition to using ZIPS panels, for soundproofing without a frame, mineral and synthetic fiber slabs are also used, which are installed on the ceiling with glue or plastic umbrella dowels.

Noise is an annoying factor and therefore has a negative impact not only on the comfort of living, but also on human health. Therefore, the desire of homeowners to protect themselves from extraneous sounds penetrating into the apartment is natural. This is achieved by soundproofing the enclosing structures of individual rooms or housing as a whole.

The maximum effect is provided by the sound insulation device on all bases of the apartment or premises - floors, walls and ceilings, but even after that it is impossible to achieve complete isolation of housing from external noise. However, it is realistic and even necessary to minimize the factor of outside sounds entering the house, so let's consider how to soundproof the ceiling from noisy neighbors from above - one of the components of the scope of work on soundproofing an apartment.

Sources and characteristics of noise

Sound is a type of wave, an oscillatory movement of air or another medium, capable of being perceived by the human ear. The human ear perceives sound waves in the range of 16-20,000 Hz.

Noise is a set of sounds that are not desirable for human perception at the moment, loud music or a cocktail of soft melodies is also noise.

Reality in the topic of noise protection of housing

Operating in R.F. SNiP 23-03-2003 "Protection from noise" defines a list of tools that construction companies must use to ensure noise protection of housing - from design to technical. But these measures, as a rule, are not enough to satisfy the wishes of homeowners, even if the noise level in the apartment does not exceed the permissible values. In the event that the actual conditions exceed the noise standards, it often turns out that non-compliance with the requirements of SNiP by the builders took place due to objective reasons, for example, the housing under construction belongs to the economy class - equipping the building with the necessary sound insulation would lead to an increase in the cost of construction by about one and a half times.

One way or another, additional soundproofing of housing, in particular, soundproofing the ceiling in an apartment, is a useful and sometimes necessary operation that homeowners most often do at their own expense.

Types of noise

Noise is a negative factor that needs to be eliminated, regardless of its nature. But in order to do it more efficiently, you need to have an idea about the characteristics of this phenomenon, which even has its own classifications.

One of the significant classifications of noise is according to the propagation medium:

• air - sound waves transmitted through the air (human speech, radio and television equipment, vehicle sounds, etc.);
• structural - vibrations propagating through solids (various kinds of vibration, scratching, cutting, etc.);

Structural noise is a type of impact - knocking.

The speed of sound propagation in solid media is many times higher than in air due to the difference in density values, so structural noise, especially impact, is a stronger irritant. However, we are not talking about targeted, accentuated sound insulation - this operation should most effectively reduce the penetration of sounds of any nature into the apartment.

The choice of the degree of performance of sound insulation

The production of sound insulation should be rational, it can be selective - with reference to the functional purpose of the premises.

For example, in a hall where the TV is on most of the time and everyone is awake, for homeowners it is not as relevant as in bedrooms or children's rooms. But for neighbors, if guests are often received in the room, the sound insulation of your hall would be very useful.

In addition, the soundproofing of the ceiling in an apartment on the top floor of a high-rise building, due to the lack of neighbors from above, is not as in demand as it is on the lower levels.

Whether it is necessary to isolate the ceiling bases in all rooms of the apartment, or limit it to selective execution, is up to the owner of the home, especially in a situation where the ceiling height is in the region of only two and a half meters, and the insulation layer will take another seven centimeters, at least.

The degree of arrangement of sound insulation also depends on the material of the building structures, the infrastructure of the area and other objective factors, without taking into account which the effectiveness of the operation may not be sufficient. Therefore, before soundproofing the ceiling in an apartment, in addition to familiarizing yourself with the technologies, it is advisable to consult with those who have already performed such decoration of rooms in your area.

The effect of a soundproofing device can be measured using a special device - a sound level meter, by measuring the noise level in the room before and after work begins.

Types of soundproof materials

The range of modern materials used for soundproofing various types of ceilings is wide enough to make the best choice for specific operating conditions.

According to the principle of operation, they are divided into sound-reflecting and noise-absorbing.

Sound-reflecting materials are dense in structure and, taking sound vibrations onto their surface, reflect it, depending on the angle of incidence. The thicker such a coating, the better the reflection, since the degree of sound transmission through the shell is inversely proportional to its thickness.

Noise-absorbing materials have a fibrous or viscous structure that dampens sound waves when they meet and does not redirect them to the other side. The effectiveness of such a shell also depends on its thickness and the individual characteristics of the material.

Important! Soundproofing material with heat-insulating properties also acts as a heater, which adds functionality to the arranged coating at no additional cost.

According to the design, soundproofing materials can be of the following types:

• rolled - mineral wool, ecowool, penofol, staple weave fiberglass, foamed rubber, felt in combination with polymers;
• sheet - mineral wool, penofol, gypsum board, basalt cardboard, staple fiberglass, cardboard puffed with sand, soundproof sandwich panels;
• plastic - vibrosealants of various types;
• decorative - cork sheet and panels, fiberglass, acoustic foam rubber.

The list of materials can be continued for quite a long time, moreover, the range is constantly updated with new developments with higher characteristics.

Functionality of anti-noise coatings

Sound-absorbing materials of a fibrous structure, for example, mineral and glass wool in rolls or sheets, successfully cope with airborne noise, but the effective layer thickness must be at least 50 mm.

Structural noises are transmitted along the supporting structures, therefore, to neutralize them, the seams between the elements are filled with the following insulating materials - vibro-sealants, silica fiber, fiberglass.

To neutralize impact noise, materials are needed that do not absorb, but gently repel the sound wave, which dampen its energy with their elastically deformable porous structure - pressed crumb sheet, extruded polystyrene foam, compositions of cork with rubber.

Important! The maximum effect is obtained by the use of a thoughtful combination of several of these materials, which are most suitable for the existing noise impacts.

Designs of noise-protective coatings of ceiling bases

How to soundproof a ceiling depends largely on the condition of its surface, more precisely, on its evenness and the choice of alignment method.

If the ceiling does not need leveling, or it is decided to level it using plastic mixtures, then after the completion of these works, a frameless installation of a soundproofing coating is performed.

If it is decided to level the ceiling with drywall, then the soundproofing layer is laid between the lintels of the frame, on which the plasterboard is mounted. Such a soundproofing device is a passing operation and, of the same name as the alignment method, is called a frame.

Sometimes a frame structure is also used on flat ceilings - when the thickness of the layer of soundproofing material and, accordingly, its weight are significant, or a combination of several types of insulators is used.

Frame method of soundproofing ceilings

There are many ways to perform soundproofing using frames. They differ in frame materials, its design and location in an insulating shell.

First of all, it is necessary to decide on the choice of insulating materials and the sequence of execution of their layers to protect against noise.

On the bearing base of the ceiling, it is advisable to mount a sound-absorbing shell (thickness from 5 cm), on top of which a sound-reflecting material will be installed on the frame.

The use of mineral wool as an inner layer has confirmed the effectiveness of this choice for many years, so consider this option and one of the frame methods, which is quite budgetary and therefore widespread.

On the ceiling, markings are made for a frame of steel ud- and cd-profiles, taking into account the thickness of the insulator. Then, with the help of a vibro-sealant, a special vibro-overlay tape is attached to the walls, on top of which ud-profiles are mounted.

Hangers are mounted on the base according to the marking, but with foam pads to isolate the elements and brackets from the base concrete. There are also ready-made brackets on sale, the so-called vibration suspension, which have a porous gasket that dampens vibration.

If mineral wool is chosen as the internal filler, then it is fixed on the ceiling, mounted on suspensions - the sheets are installed end-to-end. After filling the entire base area with an insulator, the cd-profiles of the frame are mounted to the hangers and ud-profiles. Thus, mineral wool is securely fixed on the ceiling with a frame, on top of which two more layers are mounted - from plasterboard sheets and gypsum fiber, which will act as a sound-reflecting coating.

GKL joints are sealed with special gypsum-based compounds, for example. Fugenfüller manufactured by Knauf.

On top of the arranged sound insulation, finishing is performed.

Frameless ceiling soundproofing

This method requires the evenness of the surface of the concrete ceiling base, since the insulating material, when attached to the ceiling, will repeat its profile. In addition, when using material landing on adhesive mixtures, a maximum contact area and a solid base providing good adhesion are required.

The range of noise-insulating materials offered by manufacturers today, which can be used in a frameless way, is very wide. Among them are self-adhesive materials of roll and sheet execution, sound-absorbing membranes, liquid noise insulators, and so on. But it should be borne in mind that the more advanced the technology, the more it will require financial costs. Consider one of the ways of frameless implementation of noise protection, which does not require significant investments.

Do-it-yourself soundproofing the ceiling with a frameless method is technically easier than using a base. Consider a variation of the method described above with fastening the sound insulator with plastic hollows.

Instead of mineral wool, in this case it is rational to use expanded polystyrene sheets - finishing putty on a rigid base is easier.

A sheet of mineral wool or expanded polystyrene is applied to the dried primed surface and the holes for drilling are marked with puncture marks in the corners. The mat is removed and holes of such a diameter are drilled according to the marks on the ceiling so that the fungus enters there without a gap.

Then the element is covered with a layer of PVA glue, applied to the place and temporarily fixed with fungi, slightly wedged with baited anchors so that the sheet is pressed to the base. Thus, all soundproof mats are attached to the ceiling.

A day later, the baited anchors are removed, the fungi are pulled out, and a fine-mesh (2x2; 3x3 mm) reinforcing steel mesh is attached to the mineral wool shell, piercing it with fungi at the places of the holes drilled in the ceiling and finally driving in the anchors - as a result, the cap of the plastic hollow should press the mesh with the insulator to ceiling.

The mesh is primed with a latex-based compound, and after drying, with a wide spatula, the ceiling is layer-by-layer plastered with leveling mixtures - two layers of a cement-based composition, one layer of gypsum finishing putty. After the mixtures have dried, the ceilings are painted using an airbrush.

Decorative noise protection

A variation of frameless soundproofing is the decoration of ceilings with decorative tiles made of soundproofing materials. This material eliminates the need to design the joints of elements and perform finishing - the tile itself is a finish that performs heat and sound insulation functions.

Such materials also require careful preparation of the base for finishing, but their installation takes much less time.

The price range of soundproofing materials for finishing the ceiling in an apartment is wide - from budget PVC material to expensive finishes made from natural cork or coconut fibers.

Important! When choosing a means of isolation from among the decorative ones, it should be borne in mind that manufacturers attach more importance to the decoration of such material than to its functionality, and modern decorative noise protection materials do not always justify their price.

Conclusion

Despite the responsibility of the work that is performed on such a visible base, do-it-yourself ceiling soundproofing is often more effective than that performed by employees who allow minor deviations from the technology. Therefore, given the availability of technology, it is better to follow the principle “if you want to do it well, do it yourself.”

The main gist of the article:

1. Protecting your home from noise is important.
2. Builders are not always to blame for insufficient soundproofing of housing.
3. The execution of noise protection is possible with your own hands.
4. Knowing the components of the noise factor will increase the efficiency of the final result.
5. The functionality of sound protection is more important than its artistic performance.

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. And how to do it right 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 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. Examples of such noise are the rattling of a washing machine, the clatter of heels, although the most infamous is the noise from an impact drill or hammer drill. 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 the 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 on the draft ceiling that dissipate air vibrations until white noise is formed with 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 damping of air vibrations occurs at the border of two heterogeneous 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 soundproofing pie. 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 of air environments should first be ensured, since direct transmission of airborne noise occurs most intensively. 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, the fixing of the sound insulation to the ceiling is done by means of plate-shaped dowels used in the wet façade system. 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, the concrete ceiling is glued with two layers of corrugated cardboard on silicate glue, then a temporary support system is assembled from the ceiling profile for the plasterboard. 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 is no space left for the free propagation of airborne noise in the corner junction of the wall to the ceiling, 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 dense 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, it does not rest against it. published

Stretch ceilings are rapidly gaining popularity - they allow you to create perfectly flat surfaces with a high decorative effect. But they are not able to become a sufficiently effective barrier to the penetration of noise - the soundproofing qualities of stretched PVC or fabric fabric are small.

If the noise from the upper floors becomes a real problem, then you should treat the problem comprehensively before starting the operation. This means that along with the choice of decorative qualities of the future ceiling covering, high-quality sound insulation of the ceiling in an apartment under a stretch ceiling should also be thought out.

Today, there are many materials that can create silence in the apartment, and they are quite suitable for mounting on the ceiling. Some of the sound insulators are quite popular and have been used for many years not only to reduce noise levels, but also to insulate surfaces, as they have the appropriate properties. In addition to them, brand new materials are also on sale, which are designed specifically for effective sound insulation.

Soundproofing materials for the ceiling

Before considering various materials for, it should be noted that recently stretch ceilings have appeared, the canvases of which also tend to reduce the level of external noise. The fabric structure has finely perforated acoustic type structure, due to which the absorption of sound vibrations occurs. Naturally, if only such a canvas is installed without additional sound insulation of the floor surface, the effect will be far from complete, and therefore it is recommended to install a stretch ceiling in combination with acoustic materials.

Today, to protect apartments from extraneous noise coming from upper apartments, the following materials are used:

• Various types of mineral wool or modified sound and heat insulators made on its basis.
• Expanded polystyrene, regular and extruded.
• Cork cloths and plates.
• Foam mats.
• Modern sound-proof material on a mineral basis "Texound".

Whatever material is chosen for sound insulation, a prerequisite is always the preparation of the ceiling surface for installation work and the installation of a frame for a stretch fabric, which will subsequently hide the design of the soundproof "barrier".

Soundproof materials

Ceiling surface preparation and frame installation

Installation of any sound-absorbing materials under a stretch ceiling can be done in different ways - by gluing, laying battens between the rails or fixing with dowels - "fungi". In some cases, it is better to use two fixing principles, especially when the base of the ceiling does not have perfect evenness. For example, glued or installed between the guide plates are additionally fixed with fasteners - "fungi".

Whatever soundproofing material is chosen, before installing it, it is necessary to prepare the surface well, in order to avoid poor adhesion or the occurrence of mold in the future.

• If the ceiling has a high-quality painted surface, then sound insulation can be mounted immediately. Such a surface does not require special preparation, and the painted layer will act as a primer.
• In the event that the ceiling coating is damaged, it is better to completely or partially remove it.
• The surface is then brushed over with a stiff brush to remove fine debris and dust that may interfere with the bonding of the boards or sheets.
• Further, the surfaces of the ceiling and walls go 100 ÷ 150 mm from their junction in 2 ÷ 3 layers. Each subsequent layer of primer composition is applied only after the previous one has completely dried. It is very important to process the joints of the ceiling with walls and corners well, since it is in these places that dampness and mold spots most often occur. For priming, special compositions with an antiseptic effect are used. Such a primer will create a stable film on the surface, which will not only protect against the occurrence of foci of microflora, but will also promote good adhesion of materials.

After the surfaces are primed and dried, you can proceed to fixing the guide profiles around the perimeter of the room for mounting the stretch ceiling.

• To do this, first of all, around the entire perimeter of the room, the height at which the guides will be mounted is beaten off. This process is carried out with the help of a building level and a colored marking cord, with which a straight line is beaten off on the wall. Instead of a building level, it is better to use a laser level to outline the line, which will determine the boundary for fixing the profiles immediately around the entire perimeter of the room.
• The next step is cutting the profiles to the desired size.

• Since the profile is metal and is a good conductor of noise, before installing it, it is necessary to stick a soundproof tape on the side that will be adjacent to the wall.

The tape is usually already equipped with an adhesive layer protected by a film, which is removed only before installation.

• Further, the profile is pressed against the wall with the side with the glued tape and fixed on it with self-tapping screws or dowels through the drilled holes.

Fastening is carried out in increments of 100 ÷ 150 mm. Such a frequent arrangement must be maintained, since these fasteners will be subjected to a very large load both from the mass and from the tension force of the web.

• Then, the places of installation of lighting fixtures are outlined. For them, special platforms are prepared and fixed, for example, from a bar, on which lamps will be fixed. The thickness of the beam is selected depending on the distance that the tension web will be lowered from the base base of the ceiling. The platforms must be flush with the profile installed on the walls, or provide the required distance from the canvas if recessed fixtures are to be installed.

• After that, an electric cable is connected to the places where the lighting elements are installed. The cable must be securely fastened to the ceiling or wooden elements - it must not sag.
• Further, at the places of installation of the fixtures, the fasteners included in the kit are installed so that after tensioning the web, the auxiliary parts of the devices are under it.

Now you can move on to soundproofing work. They may vary - depending on the material chosen.

Characteristics and installation technologies of soundproofing materials

Now, knowing how to prepare the ceiling for its soundproofing and install the frame for the stretch ceiling, you can move on to the materials. To make a choice, you should consider their characteristics and installation methods.

Soundproof materials MaxForte

MaxForte SoundPro- rolled sound insulation of a new generation, effectively absorbs sound. With a thickness of only 12 mm, it provides high protection against impact and airborne sound. Absolutely safe: no glue in the composition. Can be used in frame and frameless schemes with stretch ceilings.

Advantages:

• rolls without phenol and odor;
• not afraid of moisture;
• maximum class “A” for sound absorption.

MaxForte EcoAcoustic- material from acoustic sintepon (polyester fibers). Only primary raw materials are used in production. For maximum sound absorption, the material passes the technology of aerodynamic laying of fibers.

MaxForte EcoAcoustic

Advantages:

• suitable for allergy sufferers and asthmatics;
• free of phenol and fiberglass;
• resistant to moisture, do not rot;
• there is no environment for the formation of mold and insects;
• the material does not shrink and retains its shape;
• maximum class "A" for sound absorption.

The main characteristics of the material are shown in the table below:

Installation of MaxForte soundproofing is simple. The entire area of ​​\u200b\u200bthe ceiling is covered with material, and fastening can be done with ordinary dowel-fungi.

Materials based on mineral wool

Mineral basalt wool is most often used for heat and sound insulation works both on ceilings and on walls. It has good performance and is the most suitable for living quarters of all similar fibrous materials.

But it is better in our case to take not ordinary stone wool - today improved types of this material are being produced, and their names directly speak of their purpose. This, for example, "Shumanet BM" or "Shumostop" C2 and K 2.

• "Shumanet BM"

This material consists of basalt fibers and is characterized as sound absorber premium class. One of the sides of the mats is reinforced with a layer of fiberglass, which makes the surface more rigid, and the inner porous layer is well protected. Such a rigid "cover" keeps the plates intact and does not allow them to deform, and also does not allow small particles to enter the room through the perforated stretch fabric.

Schumanet panels packaging

Characteristics of sound-absorbing boards "Shumanet BM" complies with the requirements of SNiP 23÷03÷2003 "Protection from noise". The main ones are shown in the table:

	Parameter value
Standard plate size, mm	1000×500; 1000×600
Plate thickness, mm	50
Material density, kg/m³	45
Number of boards in a package, pcs.	4
Area of ​​boards in one package, m²	2.4
Weight of one package, kg	4.2 ÷ 5.5
Packing volume, m³	0.1×0.12
Sound absorption coefficient (average), dB	23÷27
Flammability (GOST 30244-94)	NG (non-flammable)
	Not more than 1÷3%

The sound absorption coefficient was determined during special acoustic tests conducted in the laboratory of the NIISF RAASN in Moscow. This material has a low percentage moisture absorption, so it can be safely used in rooms with high humidity.

• "Noise stop"

Fiberglass panels "Shumostop"

Another material for the soundproofing ceiling coating is Noise Stop. It is produced in two varieties and is marked C 2 and K 2. Therefore, if sound-absorbing boards are selected, special attention should be paid to the marking:

Name of material characteristics	Parameter value
	C2	K2
Standard plate size (mm)	1250×600	1200×300
Plate thickness (mm)	20
Material density (kg/m³)	70	90-100
Number of boards in a package (pcs.)	10
Area of ​​boards in one package (m²)	7.5	3.6
Weight of one package (kg)	11	8.8
Packing volume (m³)	0.15	0.072
Sound absorption coefficient average, (db)	26-27	20
Flammability (GOST 30244-94)	NG (non-flammable)
Water absorption at partial immersion in water for 24 hours	No more than 2%	No more than 3%

- C2 is most often used for insulation and soundproofing floors, as it is made from hydrophobic staple fiberglass.

— K2 is used for all surfaces. It is made from basalt fibers, and usually just such a "noise stop" is used for soundproofing ceilings.

Often these materials are used in combination, since C 2 has a higher sound absorption coefficient, and K 2 is less harmful to human health. Therefore, fiberglass plates are fixed in the first layer, and on top they are covered with basalt mats. When used in this way, they are able to reduce the noise level to 46 dB.

Installation of mineral wool sound insulation boards

Installation is carried out in the following sequence:

• If the noise insulator is planned to be laid between the batten guides, then first, markings are made under it on the ceiling. Having determined the reference points for the location of all elements, the lines are beaten off along which the frame guides will be fixed. These elements are fixed at a distance of 550÷600 mm from each other, depending on the width of the selected sound-absorbing boards.

For the frame, a wooden beam or a metal profile can be used. The guides should not have such a thickness that will lower them below the profile for the tension web fixed on the walls.

If metal profiles are used for the crate, then they must also be pasted over with a special tape, otherwise the effect of sound insulation will be reduced.

• The frame can be mounted directly to the ceiling or with hangers. They are fixed to the ceiling surface with dowels, and the crate elements are already fixed to them.

This option is acceptable if the apartment has a high ceiling, and it is planned to lay a thick layer of soundproofing material. This should be foreseen in advance, even when fixing the profiles for the stretch ceiling.

• The next step is the installation of acoustic material slabs. They should fit as tightly as possible to the surface of the ceiling. If the sound insulator fits into the crate, then it is recommended to fill it to its full thickness. The material must be laid at a distance between the elements of the frame.
• If the crate is not installed, then for a reliable connection soundproof slabs with a ceiling, one of the adhesive compositions is used. It could be the glue the form of a spray Recently, it has been increasingly used for installation. Another option is a cement-based or gypsum-based mounting adhesive.

The choice of composition depends on the surface on which the material will be mounted.

- For example, if the ceiling is concrete, then you can use cement or gypsum-based glue. For mounting on a painted surface, it is better to choose a spray adhesive that will perfectly fix the mats on the ceiling, without additional fixation with “fungi”. It is best to spray the glue outdoors, for example, on a balcony, and then immediately bring the mats in and fix them to the ceiling surface.

- If glue based on gypsum or cement is used, it is necessary to additionally fix the mats with fasteners - "fungi", for which through holes are drilled directly through the sound insulator mats in the ceiling with a depth of 50 ÷ 60 mm.

On each of the mats will need to use for fixing five six fasteners.

If a perforated canvas is used as a stretch ceiling, then in order to avoid fibers from mineral wool entering the air space of the room, it is covered from above with a vapor barrier film, and already on top of it is fixed with fasteners - “fungi”.

• The sound insulator laid between the elements of the crate is also covered with a membrane and fixed to the bars with staples and a stapler, and to metal profiles with double-sided tape or to the ceiling using "fungi".

After the glue, if it has been used, dries completely, you can proceed to the installation of the stretch ceiling.

Using Styrofoam Panels

For soundproofing the surface of the ceiling, different types of expanded polystyrene are also used, which are produced in a form convenient for installation in the form of plates of different sizes. Their thickness can be from 20 to 100 mm.

There are two classes of this material - ordinary, unpressed expanded polystyrene (commonly referred to as Styrofoam) and extruded. Their characteristics differ among themselves in most parameters:

Comparative characteristics of foam and extruded polystyrene foam at an average thickness of 50 mm
Name of material characteristics	Extruded polystyrene foam	Styrofoam
Water absorption in% by volume for 30 days, no more	0.4	4
Water absorption in% by volume for 24 hours, no more	0.2	2
Vapor permeability, mg/m×h×Pa	0,018	-
Thermal conductivity in a dry state at a temperature of (25+ -5), W / (m × ° C) no more	0,028 - 0,03	0,036-0,050
Sound absorption coefficient, dB	23-27	42-53
Ultimate strength in static bending, MPa	0,4-1,0	0,07-0,20
Compressive strength at 10% linear deformation, MPa, not less than	0,25-0,50	0,05-0,20
Density, kg/m2, within	28-45	15-35
Operating temperature range, °C	-50 to +75	-50 to +70
combustibility	From G1 (moderate flammability) to G4 (combustible)

• unpressed Styrofoam

This class of material is marked PSB-S, that is, self-extinguishing polystyrene foam, unpressed.

Styrofoam consists of granules of different sizes - the density of the material depends on this, which directly affects its soundproofing qualities.

To insulate the ceiling, it is better to use foam plastic, which has a low density, since the material is lighter in weight and lower in thermal conductivity. The marking itself will tell you the density - for example, PSB-S 25 or 35 is well suited for mounting on the ceiling.

Styrofoam is well attached to the surface, provided that the glue is correctly selected for it. Typically, cement-based compounds, "liquid nails" or polyurethane foam are used for fastening. As an additional fixer, “fungi” mounts are also used to the ceiling surface.

• Extruded polystyrene foam

This material has a higher density, as it is made by extrusion - forcing the molten mass under pressure through the molding nozzles.

Plates of this material often have a "castle" part of the tongue-and-groove or in the form of lamellas, which guarantees the creation of a seamless surface, and, in turn, increases the heat and sound insulation qualities of the created layer. Expanded polystyrene with a thickness of 20 mm is able to dissipate impact noise and reduce the effect of it by 20 ÷ 27 dB, and this parameter increases with increasing material thickness.

For mounting extruded polystyrene foam the same compositions are used as for non-pressed foam.

The advantages of both types of expanded polystyrene when mounted on the ceiling include:

- Light weight, which guarantees secure mounting on the horizontal surface of the ceiling.

- Resistant to mold.

- Low coefficient of thermal conductivity.

- A fairly high level of sound absorption.

The negative qualities of this material, for its use in residential premises, can be called:

— The material is combustible, and when burning, it emits substances dangerous to human life with smoke. In addition, when melting, it spreads, transferring fire to surfaces and objects close to it.

- Any polystyrene foam does not tolerate ultraviolet exposure.

- With prolonged use, the material begins to decompose on its own, releasing hydrocyanic acid, hydrogen halides, nitrogen oxides and other dangerous compounds. More prone to this phenomenon unpressed Styrofoam.

However, it should be noted that high-quality material, which includes fire retardants, is less combustible and is self-extinguishing. Such expanded polystyrene, of course, has a higher price. It is difficult to determine the quality of the foam at first glance, therefore it is recommended to familiarize yourself with the certificates of conformity, or purchase one plate and conduct experiments on it, which will determine the choice.

Installation of any type of polystyrene foam is identical. One of the selected adhesive compositions is dotted on its surface, and the plate is pressed against the ceiling.

Then through holes are drilled, and through them fasteners - “fungi” are driven into the main ceiling. Usually, only two fasteners are enough for a slab planted on glue.

If such a method is chosen, then it should be clearly understood that the ease of installation does not at all justify the very low soundproofing qualities of this material. The effectiveness of such noise protection is more than doubtful.

Sound insulator "Teksound"

"Teksound" Relatively recently appeared on the Russian market and therefore has not yet managed to gain due popularity, since not many people yet know the advantages of this material over other sound insulators. Its most important advantage, especially for apartments with small footage and low ceilings, is its small thickness, which does not hide the area at all, unless, of course, Texound is not used in combination with other materials.

A roll of modern noise insulator - "Teksaunda"

Texound, despite its small thickness, has a very high density, and is able to scatter and absorb sound waves of great intensity. Such a coating not only protects the room from unwanted noise from the outside, but also does not allow the sound waves that form inside the apartment to go beyond its limits.

"Teksound" is available in rolls or sheets packed in polyethylene. The main characteristics are shown in the table:

In addition, Texound has the following qualities:

• Resistance to temperature extremes - it does not lose its original qualities even when freezing to -20 ° C.
• The elasticity of the material makes it similar to dense rubber.
• The material is immune to moisture and has pronounced antiseptic properties, so mold will never appear on it.
• The operational period of the material is unlimited.
• "Teksound" goes well with other heat and sound insulating materials, complements and enhances their effect.

"Teksound" is produced in different sizes. It can have ordinary and self-adhesive surfaces, felt or foil addition:

Name	Release form	Standard material dimensions in mm
Texound 35	rolled	1220×8000×1.8

Installation of "Teksounda"

"Teksound" can be fixed to any base, whether it be concrete or wood, drywall, metal, plastic and other surfaces, as long as they are prepared for its installation. Preparation takes place in the same way as under any other soundproof material.

"Teksound" is installed as the only sound-absorbing material or in combination with other heat insulators.

First mounting option

In this case, "Teksound" is used as an independent sound-absorbing layer. It is glued to the surface. ceiling with special glue, which produced by the same company and sold in canisters.

Sticking "Teksounda" on the ceiling surface

• The adhesive composition is applied to the surface of the material and the wall, then a pause is made for 14 ÷ 20 minutes, and only after that the Teksaund canvas is glued to the ceiling.
• Since the material has a fairly large weight, it is glued in small sheets.
• Cloths are glued with an overlap of 40 ÷ 50 mm. After installation on the overlap, an even cut is made, then the edges of the sheets are aligned and welded together with heating from using a building hair dryer or gas burner.

• Some craftsmen prefer to glue the canvases with Sealant or Liquid Nails glue.
• Self-adhesive "Texound" Mounting is quite simple, since the adhesive layer on one side of it has already been applied - you just need to remove the protective film, press it to the surface and fix the material on the ceiling.

Easy to use "Teksound" with already applied adhesive layer

• After mounting on the adhesive, the canvas should be additionally fixed with fasteners - “fungi”, which are placed at a distance of 350 ÷ 500 mm from each other.

Additional fixation with dowels-"fungi"

Second mounting option

This option for installing a false ceiling includes several operations. They are carried out before attaching the guides for the stretch ceiling. Of course, this approach is possible only with a sufficient height of the room.

• Lathing is being installed on the ceiling, mineral wool slabs are laid - according to the technology already described above.
• Then, on the sheets of drywall, laying them on the desktop, the Texound canvases are glued.

"Texound" is pre-pasted on drywall sheets

• At the next stage, drywall with a sound insulator is mounted on the crate with self-tapping screws in increments of 100 ÷ 120 mm.
• The joints between the canvases are welded with hot air or glued with "Sealant".
• After completing the installation of drywall, you can proceed to the installation of guides for the stretch ceiling.

Third option

• In this option, "Teksound" is glued to the ceiling, as in the first installation method, it is fixed with "fungi".
• After that, a frame made of a metal profile or timber is mounted on suspensions or directly on the ceiling.

If a frame structure is required, then it can be attached after finishing the ceiling with "texaund"

• Further, one of the types of mineral wool is laid between its guides - it can be "Shumanet" or "Shumostop".
• From above, it is desirable to sheathe the frame with drywall, and only then proceed to the installation of the stretch ceiling.

Soundproofing the ceiling with acoustic foam

Acoustic foam rubber is by far one of the most affordable and effective materials for soundproofing room surfaces, including the ceiling.

As you know, foam rubber has a porous structure, which is able to scatter vibration waves and absorb vibrations. Vibration waves are especially noticeable in panel houses, since concrete walls have metal reinforcement, which is a good conductor for low and high frequency sounds.

Acoustic foam rubber has a long service life and can be used both as an independent sound insulator and in combination with other materials.

Foam rubber mats are very light, so they can be glued to any surface using ordinary silicone or even double-sided mounting tape.

When using this material without additional finishing, you can choose a color solution that will match the color scheme of the entire interior, as 10-12 mat colors are produced. Under a stretch ceiling, you can not think about the color scheme and purchase more affordable acoustic foam rubber - white or gray.

Thickness, or rather, the height of the relief pattern of foam rubber can be from 25 to 100 mm. In addition, there are several relief patterns on the surface of the material, which also allows you to make a choice.

Foam rubber reliefs have their own names corresponding to the pattern - these are "Wedge", "Pyramid" and "Wave" (tray of eggs). In addition, special-shaped foam rubber elements are produced, designed to neutralize the propagation of low-frequency sounds.

Acoustic foam rubber is not very popular for open use in an apartment, as it quickly accumulates dust. But it does not lose its soundproofing qualities at all even if it is covered with decorative material - the main thing is that the foam rubber fits snugly against the surface of the ceiling or wall. That is, for a stretch ceiling - this is an excellent option.

Installation of foam soundproofing

Fixing foam rubber mats to any surface can be called the simplest of all installation work related to fixing soundproof materials. Foam rubber can be attached to heated silicone, spray adhesive, Liquid Nails or double-sided mounting tape.

In the event that the mats are planned to be closed, for example, with drywall, you will have to make a frame crate, and the installation process in this option will consist of the following work steps:

• Foam rubber can be glued to any surface, as long as it is dry and clean.
• The mats are glued to the wall with one of the selected adhesives. It is very important that the soundproofing material adheres tightly to the surface. The adhesive can be applied pointwise or sprayed over the entire surface of the mat.

• Then, the foam rubber is firmly pressed against the ceiling and adheres for several seconds.
• Further, the next mat is mounted close to it - and so the entire surface of the ceiling is filled.
• Then, on top of the foam rubber, in the recesses of its relief, crate elements are installed, at a distance of 550 ÷ 600 mm from each other - this parameter will depend on the width of the drywall sheet, since they should find their edges at half the width of the bar or metal profile.
• After installing all the guides, electrical wiring is mounted, and sheets are fixed on top of the crate
• Next, the frame is installed under the stretch ceiling.

In this case, drywall will serve as an additional layer of sound insulation.

Another, simpler and more affordable option, can be gluing foam rubber to the ceiling, and then immediately installing a frame for a stretch ceiling, installing platforms for lighting fixtures and fasteners for them.

If the goal is to isolate the ceiling from the penetration of external noise, then from the above materials, you can fully choose the one that will be most affordable and self-assembly technology.

In conclusion, it should be noted that in order to achieve the maximum effect of soundproofing a room, it is necessary to cover the whole room with one of the acoustic materials, including walls and floors, since the reinforcing belt transmits sound very well from one plate to another. By fixing soundproofing boards only on the ceiling, you can only slightly reduce the noise coming from above.
