Can the ceiling be soundproofed? Thin ceiling soundproofing: choice of material and function

How can you protect yourself from noise?

There are 2 options here:

1. Ceiling insulation in your room. We recommend mounting the frame system on vibration-isolated hangers. Also, a slightly less effective, but still working option may be the use of ZIPS panels. The disadvantage of ZIPS panels is the lack of full vibration decoupling from the insulated surface. For those who want to avoid plastering work, it is possible to combine the installation of the frame with the installation of a false ceiling. If you do this at the same time, you will also not lose extra centimeters in the height of the room. Especially since today there are fabric options that look like a perfectly plastered ceiling. We use German stretch fabric D-Premium Descor. His device adds only 3-4 mm of thickness.
2. The second approach is isolation from neighbors. We are talking about floating floor technology, effective against airborne and, first of all, impact noise. The main thing is that the neighbors are not against its installation.

When might additional wall insulation be required?

If the walls are a noise transmission channel. We are talking about those situations where the customer is more concerned about impact noise, and in the room on top instead of a floating floor, ceramic tiles, laminate without a substrate or something similar are laid. In this case, the shock wave is transmitted from the ceiling to the walls, so they become an additional conductor of sound and exacerbate the problem. So, they also require isolation from noise.

What is a frame soundproofing system?

Frame soundproofing is mounted on site and consists of several layers.

1. First of all, the frame is assembled: Knauf profiles are attached to the surface using vibration-isolated or vibration-damping hangers.
2. The frame is filled with slabs of Rockwool basalt wool, the task of which is noise absorption: its multidirectional fibers with air voids scatter the sound wave, converting noise energy into heat. So in the end, noisy neighbors make your home ... warmer.
3. From above, the frame is sewn up with a solid sound-reflecting layer. These can be drywall sheets (GKL), or more massive sheets of weighted acoustic gypsum fiber, which have a higher sound reflection coefficient. Reflecting from them, the sound waves extinguish the oncoming ones, and the “residue” of the noise returns to the cotton wool.
4. If necessary, the sheathing can be additionally weighted with a layer of panels with sand - SoundGuard EcoZvukoizol or Sonoplat, or with a membrane if there are thickness restrictions. It should be noted the relative high cost of these materials, despite the fact that their density (1300-1400 kg / m³) is comparable to the density of gypsum fiber (1254 kg / m³). Those. if you are willing to give up a few extra mm of thickness to save 30% of the total cost, you can completely get by with an additional sheet of gypsum fiber.

It is this sequence, from the point of view of physics, that most effectively dampens sound waves. Thus, the frame system increases the absolute vibration isolation by R w =14 - 25 dB, that is, it reduces the sound volume by 3-5 times.

What is the essence of the frameless system?

This concept includes options that are attached directly to the ceiling, without a frame device. Of those presented on the market, only multilayer soundproof panel systems ZIPS deserve attention, which are sound absorbers made of stone wool and plasterboard glued together. Due to a number of technical nuances, they can only be used when performing a major overhaul of the apartment. The inability to flexibly combine the quantity, thickness and type of materials limits its soundproofing characteristics to relatively low values.

Also, some mistakenly understand frameless options as roll or membrane sound insulation, or the option of mounting stone wool on fungi. The effectiveness of this approach is practically zero, because these materials are provided by manufacturers only as part of complex frame solutions.

Why is it more often preferred to frame rather than frameless system?

The ZIPS system has serious disadvantages:

1. The rigid connection between the ceiling and the panel increases the transmission of vibration and noise, especially impact noise.
2. The mounting surface must be perfectly flat, otherwise the gaps remaining under the panels will transmit sound.
3. If the stretch fabric is not included in your plans, the ZIPS system requires re-plastering.

Thus, the preparation of the surface for the installation of frameless sound insulation and finishing increase the price per meter and the timing of the work. Therefore, it is better to install such a system during the repair period and provided that the noise level is not high.

Why is ceiling soundproofing different from wall soundproofing?

Noise "vertically" is not only and not so much loud speech or music (that is, airborne noise). From above, we are often disturbed by the sound of footsteps, the stomping of children, the sound of a ball or falling objects. This is shock noise, and it spreads differently: not through the air, but through concrete floors and walls. The structural way of sound transmission requires "its own" methods of isolation.

What determines the price of soundproofing the ceiling in a turnkey apartment?

The following factors affect the cost of the service:

• area of ​​the surface to be insulated (prices are per square meter);
• choice of technology: frame or frameless design;
• the composition of the "sandwich", that is, what materials and how many layers will eventually be required to solve the problem;
• additional installation of a tension web;
• the need for dismantling or preliminary repair work.

Is it obligatory to visit a specialist at home or can an order be placed by phone?

Even if you know the parameters of the room well, they are rather abstract for drafting a project. First, the engineer must correctly set the task, determining the nature, noise level and channels of its propagation, select the optimal design and discuss individual wishes (in terms of materials, timing, etc.). It is possible that the area of ​​the insulated surface will change. It is impossible to resolve all these issues over the phone.

Can Rockwoool Acoustic panels be replaced with another material?

It is possible, but this may affect the effectiveness of the design. In addition, its cost will increase. As a result, instead of saving, the customer can get a more expensive and less reliable option.

The experience of the work performed proved the high sound-absorbing properties of Rockwoool Acoustic wool and the optimal price-quality ratio. Note that almost all varieties of Russian-made soundproofing wool are produced at one enterprise - the ROCKWOOL plant in the city of Zheleznodorozhny, Moscow Region. So your own search for “something new” will still lead you to the materials of this manufacturer, only repainted and in a different package, with a higher cost.

Modern housing, in our view, is a harmonious combination of a magnificent interior, complemented by fashionable and comfortable furniture, stylish decor items and a variety of high-tech appliances designed to brighten up and simplify our life. At first glance, it may seem that these signs of this are quite enough to create a comfortable and cozy atmosphere in the house, however, if noise is a constant companion of your home, then it is unlikely that you will experience positive emotions, but think about the feasibility of high-quality soundproofing of the apartment.

Noise: main types and methods of elimination

More than half of the residents of modern high-rise buildings suffer from noise accompaniment: a slight movement of furniture on the floor above or a small piece of furniture falling on the floor in violation of the technology of soundproofing work mercilessly beats our eardrums. Extraneous sounds (steps, claps, sharp screams, music) enter our house not only through windows and walls, but through the surface of the floor and ceiling, thereby disrupting the normal way of life and delivering a lot of negative emotions.

Specialists distinguish between airborne and structural noise.

To airborne noises include noise caused by sound waves of fluctuations in air currents that are transmitted through walls in the presence of a powerful source, for example, loud speech or sounds from the speaker of a working tape recorder.

To structural noise include noises arising from any mechanical action, for example, hitting a falling object or drilling a surface. In this case, a sound wave is formed on a solid surface (ceiling), and since the speed of sound waves in solids is more than 12 times the speed of sound in air, such noises are heard quite clearly, for example, the sound of a drill.

There are 2 options for protecting the room from noise from above:

1. Complete soundproofing

Complete insulation is provided by all surfaces in the apartment: ceiling, floor and walls. This method is associated with the implementation of a full range of construction and repair work, which means that, for all its effectiveness, it is quite expensive. In addition, soundproofing materials take up space in the room, so it is better to carry out complete soundproofing in spacious rooms.

2. Combination of partial sound insulation with a stretch ceiling

If you began to notice extraneous noises from neighbors from above only after all the repair work was completed, then it is advisable to use partial soundproofing of the room, in particular, to provide soundproofing of the ceiling with the help of special soundproofing plates that are mounted in the ceiling space between the stretch and base ceiling.

When choosing the best and most reliable means and methods for noise protection of the premises, one should pay attention to the building material for the construction of the entire housing complex, since each material has its own characteristic operational features and different sound insulation.

Panel houses. Undoubtedly, the best solution for soundproofing apartments in panel-type houses is the full soundproofing method. This is explained quite simply. Due to the approximately equal massiveness of the walls and interfloor ceilings, the resulting noise is transmitted from the upstairs apartment down through all wall structures. Insulation of one ceiling, as a rule, does not lead to the expected effect - in addition to the false ceiling, additional sound insulation of the walls and even the floor is required.

Brick houses. For soundproofing apartments located in brick buildings with thick walls, it is quite enough to carry out partial soundproofing, for example, installing a soundproof ceiling is guaranteed to solve the problem of unwanted noise "from upstairs neighbors".

Monolithic frame houses. Heavy interfloor ceilings and light internal partitions, which are characteristic of monolithic-frame houses, contribute to the rapid propagation of sound waves. In addition, lightweight materials (hollow brick, foam concrete) from which the outer walls are made increase thermal insulation and the level of indirect noise transmission.

Soundproofing the ceiling: methods

Soundproofing the ceiling in an apartment can rightly be attributed to the most important stage of finishing work, because the quality and literacy of execution depend on the peace and relaxation of all residents. Today, modern materials and innovative technologies for performing construction work can solve this problem, regardless of the complexity and time of its detection .

Among the most common methods of soundproofing the ceiling of an apartment, experts distinguish installation of acoustic suspended ceilings and finishing with plasterboard with soundproofing material , which can be:

• foam glass,
• basalt wool,
• cellulose cotton,
• reed slab,
• fireclay,
• peat insulation board,
• polyurethane foam blocks
• staple fiberglass,
• linen mat,
• cork cover,
• coconut fibre.

To perform reliable soundproofing of the ceiling, an additional ceiling system should be installed. It could be:

1. suspended ceiling - a metal frame is attached to the ceiling, on which the plates are laid;
2. false ceiling - the metal frame is sheathed with drywall.
3. stretch ceiling - a fabric or film coating is stretched onto the installed special brackets.

The free space between the structures and the main ceiling is filled with a special soundproofing material.

Sound insulation through increased sound absorption

If the repair is already completed or there is no desire to do it, then the installation of an acoustic stretch ceiling based on a specially perforated fabric that absorbs noise well will be an effective way to reduce noise. The main condition for successful application and at the same time a deterrent is the height of the ceilings. Since the thickness of the finished structure, which guarantees a significant reduction in noise levels, reaches 120-170 mm, it is recommended to install it in rooms with a height of at least 3 meters.

The combination of an acoustic suspended ceiling and a layer of sound-absorbing mineral wool placed in the free space between the suspended ceiling and the ceilings creates a sound-absorbing structure. In relation to the room, the design functions as a sound absorber: the noise that enters the room through the floor and walls is absorbed by the ceiling surface, like an odor absorber in a refrigerator. The effectiveness of reducing unwanted noise by means of sound-absorbing structures is determined by the degree of echo of the room and the thickness of the working layer of the installed acoustic ceiling.

Gained a large number of fans cork ceiling. Fine sound-proof qualities are provided by natural origin, special molecular structure of cork and its porous structure.

The rapid development of the construction industry, the emergence of innovative technologies and high-tech raw materials make it possible to create an integrated sound-absorbing system based on the use of several soundproofing materials. It should be noted that specialists often use special soundproofing plates that are additionally installed in any ceiling structure. Such plates not only absorb noise from the outside, but also those sounds that are generated in the room.

So, there are many ways to soundproof the ceiling with your own hands. Your choice is determined only by the degree of protection required and the height of the ceilings.

Ceiling soundproofing materials

The modern market offers an extensive range of soundproofing materials for walls, floors and ceilings. High quality materials for sound insulation, a variety of design solutions and excellent technical and operational characteristics allow you to achieve high sound insulation in any room. Let us dwell on the main, most common soundproofing materials.

Immediately, we note: A decibel is such a relative value as a percentage or a multiplicity. Decibels measure the sound pressure level, numerically equal to the sound volume level. For clarity, let's translate dB into "times" and get - an increase in the sound insulation of the ceiling by 1 dB means an improvement in sound insulation by 1.25 times (in this case), 3 dB - by 2 times, 10 dB - by 10 times.

Noise-insulating material ISOTEX (Isotex).

It became possible to make effective soundproofing of the ceiling independently and without loss of space with the advent of innovative soundproofing products ISOTEX (Isotex). High efficiency with little height concealment (12-25 mm).

The installation of sound-absorbing ceiling panels provides a sound insulation coefficient of -23 dB with a coating thickness of 12 mm. The panels are based on heat and sound insulating plates ISOTEX (Isotex), and foil paper acts as a finishing coating, which reduces heat losses through the ceiling. Improved sound insulation is achieved by attaching frameless ISOTEX (Isotex) panels directly to the ceiling surface using liquid nails and assembling the panels using the tongue and groove method, which guarantees the absence of gaps and cracks, the main sources of sound penetration.

The effectiveness of the panels has been proven in practice: the panel system increases the sound insulation of the ceiling while losing much less area than when installing frame structures.

Soundproofing ceiling ISOPLAAT (Izoplat)

The use of a heat and sound insulating plate ISOPLAAT (Isoplat) 25 mm + hemmed / stretch / suspended ceiling provides reliable sound insulation in the room. ISOPLAAT (Isoplat) panels, made of natural coniferous wood without any synthetic and adhesive additives, improve the acoustics of the room and effectively absorb noise, drown out shock and airborne noise trying to break into your peace from the outside. Plate ISOPLAAT (Isoplat) 12 mm allows you to achieve a noise insulation coefficient of -23 dB, and a panel of 25 mm is sound insulation - 26 dB.

Mounting the ISOPLAAT heat and sound insulating board (Isoplat) on glue without preliminary leveling of the surface makes the process convenient and economical. The slabs are distinguished by the presence of one rough, wavy surface, due to which sound waves are scattered, and a smooth surface, which is subject to further plastering, painting or wallpapering for ceilings.

Zvukanet Acoustic for wallpaper. Soundproofing membrane for soundproofing walls and ceilings. Effectively reduces household noise up to 21dB. Both sides are protected by a layer of paper. Decorated with wallpaper. Roll length: 14 m. Size: 5x500 mm

Thanks to modern technology and new generation soundproofing materials, you can successfully combine different types of insulation. For example, a combination of a membrane that absorbs sound waves and slabs of such a functional purpose will allow you to create a highly effective soundproofing system that reliably protects both from external noise and from sounds inside the apartment.

How to properly soundproof a ceiling?

So, if you are not satisfied with the noise coming from the street or from the neighbors from the apartment above, it's time to come to grips with the soundproofing of the ceiling. To do this, you can use the services of a professional master - he will advise you and help you choose the best soundproofing method, purchase the necessary materials, and you will only have to enjoy the long-awaited silence in your apartment. However, this kind of service comes at a cost. Is it worth overpaying if you can do the whole complex of simple work yourself?

We will try to help you in this matter and consider the main options for manufacturing an effective sound-absorbing ceiling system.

The most effective sound-absorbing ceiling system is considered to be a framed sound-proofing system of a plasterboard ceiling, based on the use of sound-proofing membranes. Thanks to the use of a small amount of modern materials and reliable fastening methods, you will get optimal efficiency with a small thickness of the finished structure.

Premium ceiling soundproofing system

To install the Premium ceiling soundproofing system made of drywall with 2 layers of Texound 70 membrane and 2 layers of gypsum plasterboard, you have to perform the following sequence of work:

• stick a layer of TermoZvukoIzol on the ceiling surface;
• on top of the dowels and glue, attach the first layer of Texound 70 membrane material;
• install suspensions on rods or direct suspensions to the ceiling;
• fix the profile 60x27 and carry out the crate between the profiles. Since the design promises to be quite heavy, check the reliability of all fasteners and use at least 5 hangers per 1 sq.m.
• fill the free space between the profiles with sound-absorbing material from the rockwool mineral board (density 40-60 kg/cu.m.);
• the front surfaces of the profile, which "look" towards the wall surface, paste over with strips of Texound 70 membrane material;
• install the first sheet of plasterboard on the profile. Then attach to it the composition of the second sheet of GKL and the second layer of the Texound 70 membrane.

The highest efficiency of the "Premium" soundproofing system will be provided by an air gap of 50-200 mm between the layer of Texound 70 membrane material and the layer of mineral wool. It should be noted that the thickness of the air gap determines the thickness of the finished soundproofing system "Premium" - 90 - 270 mm. Here you will have to make a difficult choice in favor of silence or the volume of the room.

Soundproofing ceiling system "Comfort"

The installation technology of the soundproofing ceiling system "Comfort" with 2 layers of the Texound 70 membrane is similar to the installation of the "Premium" system, however, there are several fundamental differences:

1. the absence of an air gap between the first layer of the Texound 70 membrane material and the mineral plate layer;
2. GKL sheets with the Texound 70 membrane are replaced by a composition of one gypsum board and a layer of the Texound 70 membrane. The thickness of the finished Comfort ceiling soundproofing system is only 80 mm.

Ceiling soundproofing system "Economy"

The installation technology of the "Economy" soundproofing ceiling system with 1 layer of the Texound 70 membrane resembles the installation of the "Comfort" system with only minor differences:

• a layer of TermoZvukoIzol and Texound 70 membrane material is not installed directly on the floor slab;
• direct suspensions are necessarily wrapped on all sides with a Texound 70 membrane. The thickness of the finished Economy ceiling soundproofing system is only 66 mm.

Difficulties in soundproofing the ceiling

When installing a ceiling soundproofing system, you may encounter some inconveniences and difficulties:

1. all work is carried out at height, which means that installation will require the participation of two or even more people, the use of scaffolding, which you will have to rent or buy;

2. the cost of high-quality soundproofing materials from trusted manufacturers, however, as well as the cost of soundproofing the ceiling, is comparable to the cost of subsequent decorative design;

3. If moisture gets on the soundproofing structure, there is a high probability of damage to mineral or basalt wool. To avoid such risks, use a more expensive and moisture resistant material, such as cork.

You can visually familiarize yourself with the creation of the best soundproofing of the ceiling by watching the video on youtube.

Even in a well-designed apartment building with a large number of neighbors, it will definitely be noisy. And especially a lot of inconvenience in this sense creates noise from above. This statement is true for any type of house - both panel and brick. This is explained, as a rule, by the not very well-equipped soundproofing of the floors between floors. Reflected from them, any noise causes oscillations of the floor and propagates below.

In addition, there is a direct mechanical impact on the floor of the apartment located on top - steps, blows from dropped objects, etc. To solve this problem once and for all, it is worth figuring out how to soundproof the ceiling in an apartment on your own.

When deciding how to soundproof a ceiling, you must first decide on the material. There are several methods to isolate your ceiling from extraneous sounds, and for each of them there is an optimal solution in terms of material.

First of all, materials for soundproofing the ceiling must, obviously, effectively absorb sound. In addition, they must protect the ceiling from the oscillating effects of the sound wave.

In other words, the material should be chosen:

• soundproof - that is, having sufficient mass to reflect sound without creating vibrations and secondary noise;
• sound-absorbing - that is, having a porous structure that “slows down” sound due to friction.

Soundproofing panels with sound-absorbing “stuffing”, finished with massive material on the outside, are best suited for soundproofing the ceiling.

In addition, you should pay attention to such properties of the material for soundproofing the ceiling in the apartment, such as:

• thickness;
• combustibility;
• environmental friendliness, that is, the absence of harmful substances in the composition.

Modern materials most commonly used in city apartments for do-it-yourself ceiling soundproofing should be considered in detail.

Mineral wool

As before, when equipping ceilings in an apartment, perhaps the most popular material for soundproofing can be called mineral wool, which, however, can only be used in a room with a high ceiling, because. significantly (up to twenty centimeters) reduces the ceiling line.

At the same time, cotton wool effectively absorbs sound, has good fire-retardant properties, does not shrink, and is convenient for installation. However, the large thickness is not its only drawback. The main disadvantage is the negative impact on human health, which necessitates the use of high-quality insulating material. Therefore, soundproofing ceilings with its help is not the best option.

Mineral wool

polyurethane foam

The next widely used soundproofing for the ceiling is polyurethane foam. It is distinguished by its high density and good sound-absorbing ability, thanks to which it will not only protect the residents of the apartment from neighboring noise, but also provide the opposite effect. However, PPU has a serious drawback - when ignited, it forms highly toxic smoke.

polyurethane foam

A good option would be soundproofing on the ceiling with self-adhesive sealing tape. In addition to protecting the ceiling of the apartment from noise from above, it also has thermal insulation functions. In addition, the material made from environmentally friendly raw materials does not pose a health hazard.

Sealing self-adhesive tape

Other materials

Highly environmentally friendly methods of soundproofing the ceiling include the use of materials such as:

• cork and other natural raw materials (vegetable fiber, peat);
• soundproof wood fiber ceiling panels.

Regarding cork insulation, we can say the following: with all the consumer love for this natural material and with all its undoubted aesthetics, the soundproofing qualities of cork are low. So, it will not save you from noise of an unstressed nature (loud music, talking in raised tones, etc.). In addition, when using it, it is important to consider what type of flooring the neighbors have on the floor from above - only concrete screed and laminate are suitable here.

Finally, the soundproofing of the ceiling in the apartment can be equipped with foam glass, reed tiles, etc.

ceiling soundproofing design

The second thing that the soundproofing of ceilings requires after the selection of high-quality material is a well-thought-out design, which takes into account such a factor as ceiling acoustics. Only with proper design of the soundproofing of the ceiling in the apartment, the materials used for it will work with full efficiency.

Nowadays, soundproofing the ceiling with your own hands allows you to use the following methods:

• installation of soundproofing plates;
• thermal insulation composition;
• acoustic suspended ceiling.

Before using one or another method, you should make sure that it corresponds to the main characteristics of the room and the materials used, and also choose the best way to fix the noise-insulating frame.

Plasterboard sheathing

Most modern users, considering how to soundproof the ceiling, choose plasterboard sheathing, under which a sound absorber is mounted (its choice in this case is not a matter of principle: it can be polyurethane foam, vegetable fiber, mineral wool). In this case, a vibration-isolated frame is first installed, on which sound-absorbing material is applied, then the entire structure is sheathed with drywall.

Installation of soundproofing the ceiling using drywall involves the following sequence of actions:

• perimeter measurement and marking for the future frame;
• installation of brackets for installation of a ceiling structure;
• gluing the membrane to the ceiling;
• frame installation;
• installation over the membrane, between the frame profiles of the sound absorber;
• plasterboard sheathing;
• coating of joints with a reinforcing strip;
• sealing seams and fine finishing of the ceiling.

The last item may include painting the ceiling or covering it with plaster as part of the room's decor. You can also paste over the ceiling covering with wallpaper.

The main advantage of the method described above is that working with drywall sheets does not require any special skills. This material is mounted extremely simply, and even those who have no building experience can handle it.

Soundproofing stretch ceilings

Stretch ceilings with sound insulation deserve a separate discussion. Professionals believe that the sound insulation of a stretch ceiling is more effective than that of another type of ceiling. In this case, the main acoustic feature is that the sound wave is damped by the soft texture of the material, while the suspension structure resonates. In addition, independently performed soundproofing under a stretch ceiling allows the use of any sound-absorbing materials.

Stretch ceiling with sound insulation can be equipped by the manufacturer or equipped with soundproof elements independently. Ready-made stretch ceilings with sound insulation are a high-strength fabric treated with liquid polymers and varnished, which ensures the resistance of the material to moisture, fading, odors and dust.

Noise insulation of a stretch ceiling is a layer of a special polymer material placed on the wrong side of the canvas. Thanks to the loose, foamy texture of this material, the room is not only isolated from noise, but also retains heat more efficiently. In addition, it is possible to purchase a special acoustic sheet, the surface of which consists of micro-holes. Perforation improves the material's ability to absorb and neutralize sound currents.

Soundproofing the ceiling in an apartment under a stretch ceiling, performed independently, is equipped according to the same principle and in the same sequence as for a ceiling with plasterboard sheathing:

• the first step is to mount the supporting structure, the material for which is a metal profile or wooden slats;
• sound-absorbing material is laid in the cells of the frame and attached to a special glue;
• then the brackets for the ceiling canvas are mounted;
• Finally, the canvas itself is stretched. Stretch ceiling with sound insulation is ready.

Soundproofing suspended ceilings

Finally, with the exception of some nuances, in almost the same way as soundproofing the ceiling in an apartment under a stretch ceiling, isolation from extraneous noise is also arranged for a suspended ceiling.

In this case, the use of mineral wool is optimal as a sound-absorbing filler. Styrofoam (polyester foam) is also suitable, but here it should be noted that it cannot be attached to glue, otherwise, over time, the adhesive layer, due to the special qualities of the foam, will no longer hold it. As a result, an air gap is formed under the ceiling, acting as a resonator.

Suspended ceiling is very aesthetic. hides all irregularities, small cracks and other defects of the ceiling. The main steps for its arrangement are the same as in the previous cases: installation of the frame, laying insulating material, sheathing. We must also not forget about all preliminary measurements and markings for a vibration-isolated structure.

But in this case, another method of mounting the ceiling structure is also possible. It is worth dwelling on it in more detail.

First, a special primer is applied to the ceiling, if its surface is not perfectly flat. Then rails for the frame are attached to the ceiling. A roll-format material is used as a sound absorber.

It is fixed on the adhesive composition to the ceiling, after which it is strengthened with suspensions. A profile is mounted along the perimeter of the room, sheathing sheets are fixed on top - it can be either drywall or some other insulating material. This is followed by fine and decorative finishing.

Conclusion

Do-it-yourself soundproofing of the ceiling as a whole is considered. It remains to add that if the sound insulation of the house structure is very poor, and the neighbors are very noisy, or there are some other special individual circumstances, then all problems cannot be solved by soundproofing the ceiling.

In addition, it may be necessary to install soundproof structures on the floor and walls. If relations with neighbors from above are quite trusting, you can enhance the effect of ceiling sound insulation by equipping the so-called floating floor in the upper apartment (of course, by agreement with the owners).

To do this, a layer of polymer granules is applied to the floor, a layer of cork is placed on top of them, and, finally, everything is poured with concrete. Only after it dries, the floor covering is installed. There is an easier way to isolate the floor from sound waves - to lay a special path made of polyethylene foam.

True, both of these methods are only suitable if the apartment of the neighbors at the time when you decided to carry out soundproofing measures was in a state of repair.

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

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

Types of noise, options for its elimination

Depending on the source of occurrence, all noises are divided into air and structural. In the first case, we are talking about sounds generated by the action of sound waves in the air stream. This includes loud speech or music coming from the audio system and penetrating through the walls into neighboring 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, while the speed of its propagation is 12 times faster than that formed in air currents, and therefore such noises are clearly audible.

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

1. Providing complete soundproofing.
   
   In this option, it is assumed not only the sound insulation of the ceiling in the apartment, but also the floor, as well as the walls. For this, construction and repair work is carried out in full, which requires large material costs. In addition, the construction of the structure involves a decrease in the area of ​​\u200b\u200bthe room, which is not provided for in small apartments.
2. Installation of a stretch ceiling in combination with a soundproofing system.
   
   If extraneous noise from neighboring apartments is detected, after the repair is completed, it is recommended to carry out partial sound insulation, for example, install special plates in the gap between the stretch and base ceiling, so it will fit perfectly.

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

Features of panel houses

When buying an apartment in a panel house, it is better to immediately think about carrying out full soundproofing. This recommendation is explained by the fact that the massiveness of walls and ceilings between floors is approximately the same, and in the event of a noise flow, it spreads through all apartments of the riser. Mounting insulation on the ceiling alone will not solve the problem, so it is better to combine the arrangement of the suspension system with additional soundproofing of the walls and floor, as shown in the photo.

Features of brick buildings

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

Features of monolithic-frame houses

Monolithic-frame construction is characterized by the presence of heavy interfloor ceilings and light internal partitions that easily transmit 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, soundproofing for the ceiling in an apartment is the most important stage of finishing, since its quality and literacy 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 soundproofing include the installation of an acoustic false ceiling, as well as the installation of drywall sheets with nested soundproofing boards of any of the following materials:

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

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

1. suspended ceiling - plates of the selected material are attached to the metal frame, equipped over the old ceiling;
2. false ceiling - drywall is screwed over the metal frame.
3. – a film textile cover is attached to the installed special brackets.

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

Creating sound insulation by increasing the sound absorption coefficient

When repair work is completed, or if it is impossible to perform it, an acoustic stretch ceiling made of perforated fabric, which perfectly dampens sound waves, can be an effective way to reduce noise. An important condition for the use of 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, about 120-170 mm, the ceiling height should be from 3 meters.

A structure that combines an acoustic suspended ceiling with sound-absorbing mineral wool from the base to the ceiling will provide perfect insulation. The functioning is presented as follows: noise penetrating from the outside into the room through the floor and wall ceilings is absorbed by the ceiling layer. The level of effectiveness in reducing unwanted sounds is directly related to the loudness of the room and the thickness of the acoustic ceiling structure.

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

Thanks to a large number of modern equipment, technologies, environmentally friendly raw materials, a sound-absorbing system is created, which includes various soundproofing components. For such installation work, experts recommend installing plates that act as an addition to any ceiling system. Due to their special properties, not only the absorption of external sounds, but also those that are formed inside the room, is ensured.

Thus, it is possible to create high-quality sound insulation on your own, you just need to have an idea about the degree of protection and the height of the ceilings.

What materials can be used to equip ceiling soundproofing

In the conditions of the modern market, soundproofing of the ceiling is installed in the apartment - the materials for which are presented in a wide variety, without any problems. The presence of high-quality, various design solutions will help in creating impeccable sound insulation in a room for any purpose. Consider 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 in percent or multiplicity. In decibels, the sound pressure is measured, which is equal to the sound volume. If we translate dB several times, then with an increase in the sound insulation of the ceiling surface by 1 dB, there is an improvement in sound insulation by 1.25 times, at 3 dB - up to 2 times, 10 dB - up to 10 times.

Features of Isotex soundproofing material

Innovative soundproofing products from Izotex are aimed at creating effective soundproofing of a room with a minimum reduction in its area - 12-25 mm of spent height contributes to impeccable efficiency.

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

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

Features of soundproofing material Isoplaat

Heat and sound insulation boards Izoplat 25 mm thick in combination with a hemmed, stretch or suspended ceiling are reliable sound insulation for the room. The composition of the panels includes natural coniferous wood, and there are no synthetic and adhesive additives.

When using a plate of this manufacturer with a thickness of 12 mm, it allows you to increase sound insulation up to 23 dB, and plates with a thickness of 25 mm - up to 26 dB.

The soundproofing material is installed with glue without the requirements for pre-treatment and leveling of the ceiling surface, which greatly simplifies the process and reduces the cost of the work. A distinctive feature is the presence of a rough, wavy layer on one side, which allows you to disperse the sound wave. The other side of the plate is smooth - it will need to be plastered, painted or pasted over with ceiling wallpaper.

Acoustic material "Zvukanet" for wallpaper is presented in the form of a soundproof membrane, which will make good sound insulation on the ceiling in the apartment and on the walls. The amount of household noise reduction reaches 21 dB. On both sides, the system is covered with paper, on top of which wallpaper is pasted. It is offered in rolls of 14 m, 500 mm wide.

Green Glu refers to high-quality vibration and noise insulating materials, contributes to the absorption of vibration and sound waves, and can be used in combination with thin frame systems. During installation, it is laid as a layer between GVL or GKL. 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 a word, domestic and foreign manufacturers provide a diverse selection of materials manufactured using 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, consider the possibility of creating a highly effective soundproofing system from a membrane that helps absorb sound waves, in combination with similar boards.

Highlights when creating soundproofing ceilings

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

Ceiling soundproofing "Premium"

For the construction of such a structure, drywall with a two-layer Texound 70 membrane and a two-layer plasterboard is required.

Installation work is carried out in the following sequence:

• TermoZvukoIzol is applied to a pre-prepared ceiling;
• the Texound-70 membrane is attached with the first layer using glue or dowels;
• installation of direct suspensions, or suspensions on rods;
• a profile with dimensions of 60x27 is attached with a subsequent inter-profile crate. A heavy construction requires reliable fastenings and a minimum of five hangers for every square meter of material.
• a noise-absorbing mineral wool layer Rockwool with a density of up to 60 kg per 1 m3 is laid in the inter-profile gap;
• on top of the profile on the front side (it is directed to the wall surface), the Texound-70 membrane material is glued;
• the first sheet of GKL is attached to the profile, after which it is possible to install the second sheet on top of it, as well as a second layer of the membrane.

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

The difference is as follows:

• The thermosound-insulating layer with membrane material is not attached to the floor slab;
• the construction of straight 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 the installation work

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

1. Laying and fastening of materials is carried out at a height, therefore, 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 soundproofing materials offered by trusted manufacturers will cost the same price as their subsequent decorative design.
3. If the soundproof structure is exposed to moisture, then the risk of damage to the mineral wool boards will increase, which can be avoided by choosing expensive and moisture-resistant materials, such as cork panels.
