How to install noise insulation on the ceiling. How to make effective soundproofing of the ceiling in an apartment. Low density soundproofing installation

Few lucky ones do not face the problem of noisy neighbors upstairs. They either live on the top floor, or have an apartment in a building with five-meter ceilings and thick walls, or they are just lucky and the neighbors live very quietly. From time to time, the rest have to wonder what kind of furniture the neighbors are now moving, why they brought a horse in the apartment and why they need to play violin on the morning of the day off.

But the problem can be solved. Soundproofing the ceiling in the apartment will help create silence and comfort in the house.

Peculiarities

Before throwing away the life-saving earplugs, it is worth studying the intricacies and features of the soundproofing process. Although its installation does not require colossal efforts, it should be carried out after preparation and taking into account all possible nuances of the work.

The main advantage of soundproofing is that noises from the upper floor will no longer interfere with a quiet life. The second obvious plus is that the surface of the ceiling will turn out to be smooth and beautiful. In this case, you can do the work yourself. This technology is simple enough that a person who has never done this in his life could equip soundproofing. Also, among the pluses, it is worth noting that the work takes place practically without dust and dirt.

The main disadvantages of using soundproofing materials are the time and financial resources that must be spent on installation work. In addition to the insulating material itself, you will need to install the lathing and stretch ceiling, and this is already a significant amount and the need to hire specialists to install the stretch ceiling. If the beauty of the lathing and soundproofing is of no interest to anyone and you can do it yourself, since this is a rough layer, then the ceiling stretch canvas is a decorative element. It must be assembled by professionals.

A serious disadvantage of sound insulation is that it "hides" exclusively in the system of a stretch or false ceiling. If for apartments where its height is normal or average it will pass imperceptibly, then in small apartments with a low ceiling an extra 10 cm of height, which will be taken away by sound insulation, is an unaffordable luxury.

If water gets from the neighbors' apartment on top of the sealant, the ceiling will be damaged. The material will swell and lose its properties, and the stretched canvas will sag. Repair will cost no less than installation.

You can use materials that do not absorb moisture. For example, extruded polyurethane foam. But, with its great thickness, it does not belong to the most effective in the fight against extraneous noise. On the contrary, if installed incorrectly, it only exacerbates the situation.

Also, when deciding to install sound protection, you need to take into account the types of noise that are in the house. By themselves, extraneous sounds are equally disturbing and annoying. But it is important to know their predominant type, since material with different properties is needed to eliminate certain sounds. Some will reflect sounds, others will absorb.

Noises are:

Acoustic... This is an echo or reflection of sound from the walls of the room. This problem is typical of spacious apartments, rooms with arched ceiling vaults and high ceilings. This is a rarity in a modern panel house. But if a neighbor plays a musical instrument badly or listens to some kind of music, he will be heard without the arched vault.
Air... The quietest type of noise as it is caused by vibrations in the air. These are the sounds of doors being opened and closed, voices, steps. They penetrate from a neighboring apartment in a difficult way: through cracks in the floor and walls, sockets, ventilation shafts.
Drums. Continuous repairs from neighbors, the sound of a hammer, stamping - these are types of impact noise. Their source is mechanical impact on the floor or walls in the apartment on the floor above.
Structural... These are sounds that propagate through the structural parts of the building: floors, ceilings, walls, ventilation.

The material from which the high-rise building was erected is also important. One can be denser and less permeable to sound (this applies to a concrete structure with thick ceilings), the other is made of porous materials through which any noise passes freely (blocks), and the third is something in between (bricks).

In a modern panel house, the quality of the material can be different. In one case, the noise is almost inaudible, in the other it may seem that the walls and ceiling are literally made of cardboard, the sound insulation is so low. Solid brick is distinguished by a good indicator of sound insulation. It does not need a complex structure and a thick layer of additional insulation.

The situation is more complicated with monolithic-frame houses, where hollow bricks and porous blocks are used for internal partitions. They pass a lot of sounds. Here you will have to try to ensure that the soundproofing of the ceiling gives the desired effect.

Problem case - new panel houses... They have a large number of slots through which all sounds seep from above and from neighbors on the side and below.

Soundproofing the ceiling in such a house is indispensable. It is recommended to take care of both the walls and a high-quality floor screed.

With wood floors, contrary to the beliefs of many, there are enough problems. First, wood is a good conductor of sound. Secondly, if the floor is poorly installed, sound will seep through numerous cracks. Over time, wood floors will start to squeak, and worse than that sound is hard to imagine.

With a high ceiling height (4.5-5 meters), there are practically no problems with sound insulation. Such ceilings are usually found in houses of the old foundation, and in them all the walls and ceilings are so thick that the sound on the other side is unable to overcome them.

Another thing is the modern imitation of such buildings. In these, the problem with noise is relevant, and one of the common situations is acoustic noise. This does not affect the choice of insulating material. With five-meter ceilings, you can afford to mount a layer of any thickness. The features of installation work are more important here. It is already dangerous to carry them out on your own, and in order to get to the very ceiling, you will need to erect scaffolding.

Rooms with a height of about 3 meters are considered the best option. At such a height, you can carry out installation work yourself, and removed 10-20 cm from the height will not significantly affect the interior.

The most difficult case is “Khrushchev buildings” and rooms with a ceiling height of no more than 2.2 m. They look squat even without a stretch canvas and limit design possibilities. When a few centimeters are taken away from such a height, the ceiling begins to visually “press” from above.

The most effective (but least likely) option is to negotiate with neighbors and, at your own expense, lay a thin layer of soundproofing material on their floor. This is much more reliable than protecting yourself from noise only from your side.

Types of materials and their characteristics

Modern soundproofing materials are virtually identical to wall and ceiling insulation. All the same sheet, plate and spray materials are used as a means of protection against extraneous noise in the apartment. The use of foam rubber, wool of various origins is widespread: rolled mineral wool, ecowool, basalt or stone wool, based on fiberglass.

Often used materials like foam and its modifications in the form of foam and polyurethane foam (polyurethane foam). They are slabs that can be conveniently cut into pieces of the desired length and width. These materials tend to be thicker than others because they are coarse and porous. The exception is sprayed polyurethane foam, but it is rarely used in the arrangement of soundproofing the ceiling.

Glass can also be foamed. It is produced in the form of sheet material and in spray cylinders.

Soundproofing products based on plant and natural raw materials are gaining popularity: cellulose, cotton, bamboo and coconut fiber. If ecowool is still risky to use under a stretch ceiling, since there is a risk of dust, then bamboo and coconut fiber with their unique properties can compete with cotton wool and foam. Literally healthy (antibacterial, dirt repellent, biostable), but expensive. At the same time, sound insulation is not the most effective.

Also, not the most effective material, but suitable for apartments in brick houses and private cottages, is cork sheets. The insulation turns out to be thin and saves in not the most deplorable cases.

The plasterboard layer improves the quality of the cork material, but in this case its advantage is lost - its small thickness.

As an alternative, manufacturers have started to produce composite self-adhesive materials. This is the so-called membrane sound insulation. Basically, the membrane sheets are glued to the ceiling like linoleum to the floor or very thick wallpaper. The composition contains felt and materials that reflect sound.

From modern means, liquid insulation is worthy of attention. It is applied to the working surfaces with a special gun, but is not used by itself, but serves as a "filling" in the layer between the drywall sheets.

Foam rubber

Foam insulation is practically the same as polyurethane foam insulation. This name has become a household name due to the fact that the main supplier of polyurethane foam was called "Porolon" during the Soviet era.

Of course, the insulation material differs radically from that thick, loose yellowish dust collector, which many imagine when the word "foam rubber" is used. Even its name is appropriate - acoustic foam rubber.

It is actively used for noise isolation in recording studios, large offices, restaurants and other places where silence is necessary for high-quality and productive work. The material is produced in the form of slabs of various sizes and shapes, its outer surface is embossed (wavy or "jagged").

The advantages of foam rubber are that it is easy to install (self-adhesive or on an adhesive solution), gives a good result, elastic and flexible, which allows it to be used on a ceiling with rounded corners. Easy to cut, does not collect dust.

Acoustic foam rubber isolates not only sounds coming from outside, but also coming from the room. The neighbors will be grateful for this isolation. The disadvantages are that it requires careful handling and is prone to burning. In the process, it emits toxic smoke and loses its properties under the influence of ultraviolet radiation.

Mineral wool

Often this material is chosen to make sound insulation and thermal insulation at the same time. But still, it is more intended for insulation than for achieving the decibel standards recommended by SNiPs.

Cotton wool reduces noise due to its structure of fibers, between which there are air spaces, and different thicknesses of the fibers themselves.

There are three types of wool: mineral, stone and glass wool. Each variety has its own characteristics, fiber size, technical characteristics.

All types can be used for noise insulation, but the density of the material must be taken into account. The higher it is, the more reliable the insulation will be. For example, cotton wool marked P-75 will be of little use, and PPZh-200 is able to solve problems with sound insulation for different types of noise.

Stone wool has the highest density. With an increase in density, the price also increases, but sound insulation is not the case when it is worth agreeing to half measures for the sake of economy.

The advantages of the material are that it meets all building codes, serves for a long time, does not accumulate dust, does not emit toxins, and is resistant to deformation and shrinkage.

The disadvantages include a thick layer of the entire structure as a whole, the instability of cotton wool to moisture, the need to use waterproofing. Without protection from water that can get on the cotton wool when a neighbor's apartment is flooded, the material will swell, become heavier, and lose up to 70% of its properties. Drying or replacing it will be a separate problem. Mineral wool shrinks over time.

Expanded polystyrene

The material is known as extruded (expanded) polystyrene. Its predecessor is Styrofoam, which everyone has seen at least once in their lives.

Styrofoam can also be used as a sound insulating material, but the result from the use of polystyrene and its derivatives cannot be called impressive. With a slab thickness of 40-100 mm, it still needs auxiliary materials that absorb and reflect noise.

Expanded polystyrene has some advantages. For example, it is suitable for insulation in rooms where the problem of noise is not as acute as in thin-walled panel buildings. It is lightweight and does not load the suspended ceiling.

It is possible to dispense with the installation of the frame in some cases. It also costs significantly less than mineral wool or acoustic foam, and is hydrophobic. If water flows from the neighbors from above, the material will not suffer and will not lose its properties. For these reasons, the ceiling is insulated with foam.

Penofol is used as an auxiliary element. Penofol is a thin reflective material based on polyethylene foam.

Such layering practically does not give results in terms of sound insulation. All materials are more focused on keeping warm in the room.

Cork cover

Many people choose cork insulation because the manufacturer promises serious noise reduction figures (about 20 dB). But if you think about it, the numbers are deceiving. And the point is not that the cork is not able to reduce the noise by such a number of dB, but that such a noise level does not exceed the sound of a human whisper or a ticking clock. This is nothing when it comes to regular stomping from above, continuous repairs and other unpleasant sounds.

But low efficiency is not so bad. The problem is that cork materials are capable of insulating against impact noise. That is, they drown out the sound only when the insulation is installed not under the stretch ceiling, but on the floor of noisy neighbors above.

In other cases, the effect is achieved only due to self-hypnosis and a small air gap between the stretch ceiling and cork sheets. If we have already opted for cork insulation, then it will be correct to combine it with other materials. For example, sheathe with plasterboard. This will increase the chance of finding the desired silence in the house.

The advantages of the material boil down to the fact that it is convenient for installation work. The cork backing is lightweight, easy to cut, easy to attach. The disadvantages of the material, in addition to the fact that it is almost useless in itself, includes its fear of moisture and the need to use waterproofing.

Acoustic membranes

Latest generation materials available on the market in the form of thin sheets, plates and belts. Sheets can be record thin - only 3 mm. Maximum - 15. Sheets are laid on the surface of the ceiling (floor, walls) and between materials. They help protect against impact noise. Ideally, the material should also be lined on the floor in the apartment where the noise source is located.

The tapes isolate such paths of extraneous sounds entering the apartment as ventilation pipes, drains, cracks, risers. They are aimed at reducing acoustic and airborne noise. Membranes are produced by several companies in Europe and Russia. Popular are Tecsound, Topsilent, Green glue, Zvukoizol, Shumanet.

Each manufacturer has its own secret. Most often, the material consists of several thin layers, has a large weight and high density. An acoustic sandwich is obtained by combining several layers of foam felt, polyurethane foam or polystyrene. It can also contain components of rubber, eco-fiber, foamed glass, stone wool, rubber, foam, plasticizers, mineral and plant components, reflective materials.

The advantage of the membrane is that it is a roll material of small thickness, which is glued to the ceiling or stretched under it and does not take up much space. This makes it possible to solve the problem with extraneous sounds and not lose precious centimeters in a small room with low ceilings.

Installation of thin roll material is simple and convenient. A special glue is provided for it, which is diluted like wallpaper. Some species have a self-adhesive backing. The disadvantages of the material are that with large differences in the height of the ceiling, it will first need to be leveled. If the rolls are skewed, they will become less efficient due to gaps in the web.

In addition, the material is heavy. Installation requires at least two pairs of hands. It also means that the base of the ceiling must be well finished and primed to increase adhesion. The price per roll is not the most pleasant. Membranes of European production cost about 8000-9000 rubles. 3 meters per roll.

Other options

There are a lot of alternative options for soundproofing the ceiling. In this case, both specialized and adapted materials are used. Since it is still closed from above with a decorative stretch ceiling, only the quality of the insulation is important, and not its appearance.

Materials used to arrange insulation:

Granular elastic noise plastic. These are small balls of extruded foam with added rubber and an acrylic backing. Traditionally they are used as insulation for a "floating" floor screed, but when pressed, it is convenient to use it as a material for an interlayer between the stretch ceiling and the ceiling of the upper floor.
Acoustic sealant. This is a liquid substance that does not cover the entire area of the problem surface, but treats individual zones. These are seams, joints of plates, cracks through which extraneous sounds and vibrations penetrate into the room. The product is based on silicone resins and mineral additives. Compatible with any materials.

Panels and underlays designed for insulation under flooring. They give the maximum effect if you put them in the neighbors' apartment from above, and then mount them under your ceiling. The silence will be almost like a library.
Damper tape... It is a budget-friendly alternative to acoustic tapes for treating ventilation shafts, joints and cracks. It costs many times cheaper, and in terms of efficiency it is almost not inferior to them. In addition, the main purpose of the damper tape in repair is to prevent wall cracking, as a rule, after pouring a cement screed. And this is a very large load, which indicates the high density and strength of the tape.

Drywall. Not used by itself. Usually acts as an intermediate component or, on the contrary, covers other materials on both sides. As a rule, it is combined with thin sheet materials or liquid insulation.
Roll materials based on bitumen. They are petroleum bitumen, cellulose fiber or felt, modifiers. They are mainly used for floor insulation, but also suitable for ceilings. Due to their small thickness, but good efficiency, it is advisable to use them in rooms where space saving is important. Can be combined with other materials.

Mastic to absorb vibrations and sounds. It happens on the basis of silicones, resins, bitumen, acrylic. It is applied in liquid form in several layers.
Spray-on cellulose insulation. Eco-friendly and effective insulation, but has several significant drawbacks. This is the high cost of material and procedure, the need to use special equipment, and difficult dismantling.

Sprayed PU foam... Has the same advantages and disadvantages as cellulose spraying. All materials applied in this way require pretreatment of the ceiling surface to improve adhesion.
Sprayed glass fiber. The most expensive, but also the most effective of the sprayed options. If the financial issue is not acute, it is worth giving preference to it.

Wood fiber materials... There can be several types of them. Plywood is cheap and cheerful, but not very effective, in contrast to softwood ecoplite. In difficult situations, when the noise level exceeds 25 dB, ecoplates will not be able to help. Also, they cannot be used in a room with a low ceiling - they will take away 10-14 cm in height. But the slabs have an important advantage: they already have a decorative surface on the front side. No false ceiling required.

Plates with different designs on the outside (imitation of the texture of wood in different colors) snap into place according to the tenon-groove principle, like parquet boards. This reduces the financial cost of finishing the ceiling and saves time.

The third type is soft fiberboard... They are made from coarse wood fiber without any additives. The wood is split and then "dumped" like wool. It is used as a felt material, but it has a large number of positive properties. Among them are antibacterial properties and the ability to disinfect indoor air. However, pine needles can cause allergies.

For allergy sufferers, birch fibers or board material based on raw materials of coconut, flax and bamboo are more suitable. Such slabs can be mounted either on their own or under a plasterboard layer.

Ecoplites from volcanic raw materials and glue... Particles of volcanic origin that have undergone special treatment (expanded clay, perlite fibers and others) are glued together using the safest glue - PVA. This soundproofing is recommended for use in children's rooms.
Polyester hypoallergenic fibers... Polyester is also used in children's rooms and rooms where people with allergies or asthma live (the material does not accumulate dust).
Multilayer cardboard filled with quartz sand. One "block" of such cardboard weighs about 10-15 kg, which makes it dense, and the density of the material is the key to its effectiveness in the fight against noise.

Installation technology

Soundproofing the ceiling with your own hands is a completely doable task. But this does not mean that you will not have to face some difficulties.

For example, one-handed installation of lightweight porous materials requires a flat work surface and preparation. And the installation of heavy roll materials such as acoustic membranes cannot be done alone. Although they are 3-15 mm thick, they weigh about 30 kg. Lifting such a weight with outstretched arms above oneself is not only difficult, but also traumatic.

Another important aspect is that only the ceiling finish with insulating material is considered partial. An effective system should cover all surfaces of the room area.

Since sound tends to pass through cracks in walls, ventilation and ceilings, and noisy neighbors can live not only on the floor above, you need to isolate the entire room as a whole. This is many times more expensive, longer and more difficult than finishing the ceiling, and also affects the useful and visual volume of the room.

But effective sound insulation is often not the one that is performed in your own apartment, but the one that is located in the same room with the noise source. Only understanding neighbors will agree to lay insulating materials on the floor in their apartment. Even at someone else's expense. All this does not mean that attempts to rid oneself of extraneous noise by soundproofing the ceiling will not work. They are capable of attenuating noise of 30 dB on average.

To understand what the result will be - minus 30 dB of noise - you need to listen to the refrigerator working in the kitchen, and then turn it off for 5-10 minutes. The difference will be felt right away.

The success of the event depends on two things: the correct choice of insulating material and quality installation. The type of house is considered a universal criterion for selection. In some cases, the height of the ceiling also plays a role, but here the decision must be made individually - is it worth sacrificing 10 cm of the height of the room or is it better to put up with extraneous sounds.

In a brick house, materials are needed to isolate air (acoustic) noise. The construction of brick high-rise buildings is not solid, so the percussive sounds die out as the apartment moves away from the noise source. The brick itself is worse at transmitting sounds. But they have a more common problem with airborne noise. Therefore, it is important to use lightweight, but multi-layer structures.

For example, sound insulation made of plasterboard and cork materials, alternating drywall with polyester blocks or wood fiber boards would be good protection. Drywall with polyurethane foam, mineral wool, liquid insulation is also suitable.

In a panel house and a monolithic house, the problem is the same - the propagation of shock noises practically throughout the house. If the neighbors started repairs from above, everyone will know about it. But the bottom and top floors come first. This is due to the fact that a monolithic house (as the name implies) is a one-piece structure in which all partitions and walls are of the same thickness. And if the slabs are also hollow inside, this is a double problem.

When choosing a material for sound insulation in a panel and monolithic house, it is important to take into account the thickness of the floors. If it is less than 220 cm (and this is often a phenomenon, in "Khrushchevs" - about 120 cm), first you need to eliminate this disadvantage by "building up" the thickness. Here, lightweight materials are suitable and the creation of "air" layers between the suspended ceiling and the ceiling finish. And after eliminating problems with insufficient floor thickness, a thin, but very dense material should be mounted.

The peculiarity of dense material is its high weight. Acoustic membranes, cardboard blocks filled with quartz sand, basalt wool, OSB slabs are suitable.

It is important to consider that soft materials predominantly absorb sound, while hard materials reflect. None of the materials perform these functions at the same time, so it is recommended to use layering. First, sheathe the ceiling with reflective materials, then mount the absorbing ones and reinforce all this with an air cushion between the stretch ceiling and the insulation.

From the point of view of installation technology, sound insulation on any surface can be frame and frameless.

Wireframe

It involves the construction of a frame made of steel (less often - wooden) profile, on which sound-insulating materials are laid. This technology can be afforded by the owners of apartments with a ceiling height of about 3 meters. Otherwise, the frame structure will "eat" a lot of usable area of the room.

Installation is carried out in stages.

Calculation of materials

This is a difficult and responsible stage that includes several steps.

Step one - calculating the sound insulation index. It can be determined by the thickness of the partitions and finishing materials. It is better to consult a specialist, as it is easy to make mistakes. For self-measurement, there are such guidelines: in the daytime, an acceptable (does not mean "not annoying") noise level - up to 40 dB, at night - up to 35.

Overlappings between apartments of 200-220 cm plus a floor screed from neighbors on top are able to isolate noise up to 54 dB, provided that they are made conscientiously, in compliance with building codes and regulations.

For comparison, the cries of an adult and the cry of a child are 70-75 dB. No partitions according to SNiP will protect against them. It follows from this that for effective sound insulation it is necessary to "increase" the thickness of the ceiling at least to a resistance of 60 dB.

For an overlap with a thickness of 220 cm with a high-quality screed, one layer of cork and drywall will be enough from the neighbors on top. In a thin-walled panel house, more effort will have to be made.

An easy way to calculate the required protection is to listen to the sounds from the neighboring apartment. The sound of footsteps is about 30 dB, talking - 45, shouting - 70.

Step two - calculating the absorption coefficient. This procedure is difficult for a layman. It is recommended to select materials with a noise absorption coefficient between 0 and 1.

Step three - calculating the amount of materials... Here we are talking not about the thickness, but about the total amount of all materials. It is calculated quite simply. Measure the width, length and height differences of the ceiling. By multiplying the width by the length, you get the total area. Then this figure must be divided by the footage per roll or the size of the slab of slab material in order to calculate how many sheets or slabs are needed for the ceiling. The resulting number is rounded up, plus 10% of the stock material.

The length of the profile for mounting the frame must take into account the length of one strip and the step width. The width of the step through which the planks are mounted should be equal to 30-40 cm plus rubber for gaskets in the places where the plank is attached to the ceiling. This is an important point because metal conducts sound very well. Without rubber gaskets, the frame will only exacerbate the noise problem.

For hydrophobic materials, waterproofing must be provided. This material is also purchased by area size plus 25% for overlaps and wall allowances. A damper tape is needed for fixing to the wall.

Preparatory work

These include the choice of tools and materials, work surface treatment.

Required materials: steel profiles, hammer drill, fasteners, screwdriver, level, tape measure, putty, sealant, sound-absorbing fibrous materials (for crevices), elastic rubber gaskets, metal scissors, sound-absorbing and sound-reflecting material. Stepladders or stable high structures will be needed.

Preparing the work surface means removing old lime, paint, decorative materials from the ceiling. It is also important to make its surface as flat as possible in order to mount the frame without distortions.

For leveling, ready-made mixtures are used. It is important to take into account that before leveling, the ceiling must be primed in two layers for better adhesion to the substance, and then let each layer dry well. The leveling layer itself can dry from 1 to 3 weeks. It is impossible to mount the frame on a damp ceiling.

Processing cracks, risers and joints at the ceiling-wall interface

Processing of cracks, risers and joints at the ceiling-wall interface.

According to building codes, for high-quality sound insulation, there should not be a gap of even a few millimeters between the floor slabs. Otherwise, it creates an unobstructed path for sound to penetrate between rooms. In fact, this rule is often neglected.

The situation can be remedied if all cracks are cleaned of debris and dust and filled with a non-hardening sealant. Acrylic will do. Large gaps can be pre-filled with felt or wood fiber materials and then sealed.

The situation is reversed with risers. When building a house, they are supposed to be isolated from the overlap with a special nozzle, and the risers themselves from the nozzle - with a sealant. To save time and budget, the nozzle stage is skipped at almost any facility. Due to the temperature difference inside, the pipes of the risers expand and contract, gaps and cracks appear between the walls of the pipes and the masonry. This also reduces the effectiveness of the soundproofing. Such areas require filling with a non-hardening sealant. On top of the areas treated with sealant, you need to putty.

Along with sealing cracks, it makes sense to process sockets with electrical shields. They have no direct relation to the ceiling, but they are also sources of noise transmission. It is important to consider two points: the processing of gaps and cracks around the outlets is carried out only after a power outage, the materials must be non-combustible.

Installation of a frame from profiles

Performed step by step:

Installation of soundproofing material. It has a small thickness and high density, and also levels the surface before installing the profile.
Installation of anti-vibration suspensions. These are small parts on which the guide profile is attached. Either a vibration pad should be provided in the suspension structure, or they should be mounted on an elastic rubber pad. Step - from 50 to 90 cm.
Installation of the guide profile. The profile closest to the wall is at a maximum of 15 cm from the wall. The step is determined independently - from 50 to 60 cm. It is attached to the hangers with 4 screws per 1 hanger. The guide profile can be extended in length.

Installation of an auxiliary profile. It fits across the guides. The step is 40-50 cm. The exact distance is chosen in accordance with the sheet material, for example, drywall.
Filling the profile with sound-absorbing material: cotton wool, plates, sheets.
Installation of the frame. Basically, it is carried out from drywall in 1-2 layers. Sheet thickness - 10-12 mm. If two layers of drywall are mounted, then the joints should not match. In order to perform the separation of the joints, the sheets of the upper layer are laid in a different direction. The joints are sealed with an acrylic based sealant. They also close the seam at the points of contact between drywall and walls.
If the structure touches the risers, then the pipes must be pasted over with damper tape or similar self-adhesive material.

Installation of decorative coating on the ceiling

For soundproofing without the installation of a steel or timber frame, the materials are attached directly to the ceiling surface. For fastening, dowels and screws, special fasteners with wide heads and elongated legs, glue are used.

Such insulation is used when the height of the ceiling does not allow taking away several tens of centimeters from the room, for example, in "Khrushchevs". The second case is the operational state of the house, which does not allow mounting a too heavy structure on the ceiling. The third - when materials and technologies were used in the house during the construction to protect against noise from the neighboring apartment, but these measures need to be strengthened with additional insulation.

Frameless

Frameless soundproofing is also installed in stages:

The choice and calculation of materials is similar to the calculation for a structure on a frame... If you plan to lay sheets or slabs in two layers, then the amount of materials on the ceiling area doubles. Dowels for fastening panels are used only plastic, since steel will conduct sound and reduce the efficiency of the structure.
Surface preparation. Many materials are glued with glue or have a self-adhesive backing, so it is especially important to treat the ceiling surface for frameless sound insulation. But before that, all differences in height and unevenness are eliminated. All preparation includes three important steps: cleaning the surface from paint, dust, decorative coating; expansion of cracks, blowing and filling them with a sealant, applying a leveling layer. After the leveling layer has dried, the surface must be primed in two layers.

Installation of material. Several options are possible here. Can be glued to a self-adhesive backing, glue, or fastened to dowels with a (fungus) shaped head. It is wide, flat and with perforated holes and holds well cellular or fibrous slabs. The best option is to fix the products with glue, and for additional insurance, install dowels with a step of 90-100 cm.
Joint processing... Plates and sheets do not adhere tightly to each other. It is recommended to seal the joints with damper tape or fill with sealant. You can layer materials in 2-3 layers.

Thoroughly clean plaster, paint and whitewash from the ceiling surface. The better the work surface is prepared, the stronger the frameless insulation will hold.
If the height of the room allows, choose a suspended frame, rather than frameless sound insulation.
The best insulation, especially for the first floor, is not partial (ceiling only), but complete (walls, windows, doors).
Avoid cheap materials. Good soundproofing costs good money. The budget material does not give the maximum effect.

When choosing ready-made acoustic membranes, pay attention to the manufacturer's reviews and reputation.
Prioritize weight and density over material thickness. 20cm foam is less efficient than 4cm wood-based panels.
Combine materials for sound absorption and sound reflection.
Improve the efficiency of sound insulation by sealing cracks, joints, processing cracks around outlets, risers, electrical boxes.

What types of noise are there?

As a rule, neighbors from above bother you not only with loud speech, music or TV work, but also with sounds of a different nature. Footsteps, pounding, clattering from pets' claws, hitting the floor with a ball and other similar noises are percussion noises. Unlike air, they have a different distribution pattern.

Air - collides with a wall or floor as if it were an alien environment, which significantly absorbs it.
The impact arises directly on the surface, and spreads along the concrete further along all adjacent walls.

This type of sound wave propagation is called structural. Due to the different nature of the strike and air types, the methods of dealing with them are different. What is effective for eliminating one type of noise does not work so well for another.

Why do I hear everything that happens in the neighbors?

Today, when designing and subsequent construction of houses, a certain sound insulation index has already been laid down, which is determined by the massiveness of the floors. For example, a hollow-free 140-mm reinforced concrete slab, which is widely used as ceilings, has an airborne noise insulation index of Rw = 50 dB. In this case, it is assumed that an additional leveling screed will be made. With an added thickness of 4-6 cm, another Rw = 2 dB is added.

As a result, we obtain the final index recommended by SNiP in Rw = 52 dB, indicated in the current edition of the “Code of rules for noise protection” (SP 51-13330-2011). This is quite enough not to hear the conversation in the usual tone, the volume of which is 40-45 dB. But in order to completely drown out loud conversations (70 dB), laughter and shouts (75 dB), loud music or home theater (from 70 to 90 dB) - this is clearly not enough. It turns out that for acoustic comfort the initial Rw index of the structure should be increased by 15-20 dB.

There is also a percussion type noise. Unfortunately, SNiP does not necessarily imply a device for neighbors on the floor of a floating screed. Therefore, we hear how they walk above us in heels, children run or pets clatter their claws.

Problems are solved by installing sound insulation in your apartment, which provides a total Rw index in the range from 65 to 72 dB.

How to make soundproofing from upstairs neighbors?

The most popular complaint from residents of high-rise buildings is loud noises from neighbors upstairs. There are 2 ways to solve this problem: by making insulation inside your room or from the side of the neighbor on top. The second option will be much more effective, since with the correct implementation of the floating floor technology, it allows you to get rid of both impact and airborne noise.

If it is not possible to agree on the installation of a floating floor in the room from above, then soundproofing the ceiling from neighbors may be sufficient to eliminate airborne noise. It is worth using suspended ceilings with sound insulation on a separate frame, acoustic canvases themselves are ineffective. They are designed to reduce echoes within your room.

To combat airborne noise, thinner systems are sufficient, which practically do not reduce the height of the room. We present them as "Thin" and "Optima".

Floating floor for neighbors

Frame construction in your apartment

If you are concerned about the noise of impact origin, which is more characteristic of the indirect transmission of sound along adjacent ceilings and walls, you will need to understand the channels of its propagation. It will be especially problematic when the upper tenants have tiles or laminate on the floor without a floating screed and even without a backing. In this case, the walls are an additional conductor of extraneous sounds. Therefore, in the apartment, in addition to soundproofing the ceiling, it is likely that several walls will also need to be soundproofed.

The nature of the indirect transmission of sound waves for different rooms is different. It depends on the types of enclosing structures, what materials are made of, and how they are connected to each other. You can independently determine on which walls the transmission of sounds from neighbors is strongest. To do this, with especially loud sounds from neighbors on top, put your ear in turn to all the walls. Those walls from which you can especially clearly hear what is happening above you also need to be isolated.

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 coming from neighbors. To eliminate it, it is enough to install a good soundproofing system.

Varieties of noise, options for its elimination

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

The source of structure-borne noise is mechanical action - 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, therefore, such noises are clearly audible.

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

Providing complete soundproofing.

This option assumes not only noise insulation of the ceiling in the apartment, but also the floor and 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 reduction in the area of \ u200b \ u200bthe room, which is not provided for in small apartments.
Installation of a stretch ceiling in combination with a soundproofing system.

If extraneous noise from neighboring apartments is detected, it is recommended to carry out partial noise insulation after the completion of the repair, for example, install special plates in the gap between the stretch ceiling and the base ceiling, so it will fit perfectly.

When choosing the optimal and reliable methods for protecting a room, it is recommended to take into account the characteristics of the building as a whole, since each of them has its own operational characteristics and 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 complete soundproofing. This recommendation is explained by the fact that the massiveness of the walls and ceilings between the floors is approximately the same, and in the event of a noise flow, it spreads to all apartments of the riser. Installation of insulation on the ceiling alone will not solve the problem, therefore it is better to combine the arrangement of the suspension system with additional noise insulation 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 enough to eliminate unnecessary noise, for example, installing special materials on the ceiling.

Features of monolithic-frame houses

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

Regardless of the type of noise insulation for the ceiling in an apartment, it is the most important stage of finishing, since its quality and literacy determines the level of comfortable and quiet rest of 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 soundproofing ceilings include the installation of an acoustic suspended ceiling, as well as the installation of plasterboard sheets with embedded soundproofing boards of any of the following materials:

foamed glass;
basalt wool;
reed slab;
chamotte;
peat insulation boards;
polyurethane foam blocks;
staple fiberglass;
linen tow in mats;
cork cover;
coconut fiber.

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

suspended ceiling - slabs of the selected material are attached to the metal frame installed over the old ceiling;
false ceiling - drywall is screwed on top of the metal frame.
- a textile cover made of film is attached to the installed special brackets.

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

Creation of sound insulation by increasing the sound absorption coefficient

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

With the thickness of the structure, which successfully reduces noise, of the order of 120-170 mm, the ceiling height should be from 3 meters.

The structure, which combines an acoustic suspended ceiling and sound-absorbing mineral wool between the base and the floor, will provide perfect insulation. The operation is presented as follows: noises that penetrate from the outside into the room through the floor and wall ceilings are absorbed by the ceiling layer. The level of efficiency in reducing unwanted sounds is directly related to the room's boom and the thickness of the acoustic ceiling structure.

The cork ceiling is in great demand among consumers. Such 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 sound-insulating components. For such installation work, experts recommend installing plates that act as an addition to any ceiling system. Thanks to their special properties, not only the absorption of external sounds, but also those that are generated 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 of the degree of protection and the height of the ceilings.

What materials can be used to equip the ceiling sound insulation

In the conditions of the modern market, noise insulation of the ceiling in the apartment is installed - the materials for which are presented in a wide variety, without any problems. The availability of high-quality, various design solutions will help in creating perfect sound insulation in a room for any purpose. Consider the basic, most common materials.

For a complete understanding of the properties of materials, a definition of the concept of "decibel" should be given. It is a relative value in percentage or multiplicity. In decibels, the size of the sound pressure is measured, which is equal to the sound loudness. If we translate dB by several times, then with an increase in the noise insulation of the ceiling surface by 1 dB, an improvement in sound insulation is observed by 1.25 times, at 3 dB - up to 2 times, 10 dB - up to 10 times.

Features of noise insulation material Isotex

Innovative soundproofing products from the Isotex company are aimed at creating effective soundproofing of the room with a minimum reduction in its area - 12-25 mm of the 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 construction is based on several Isotex heat and sound insulation boards, and the topcoat is made of foil paper, which reduces the amount of heat loss from the ceiling surface. Improvement of sound insulation properties is guaranteed by frameless Isotex panels, which are attached to the ceiling with liquid nails, and are also assembled with a thorn-groove connection, which prevents the presence of gaps and crevices, through which extraneous sounds usually penetrate.

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

Features of Isoplaat soundproofing material

Heat and sound insulation boards Izoplat 25 mm thick in combination with a hem, stretch or false ceiling are reliable sound insulation for the room. The panels contain natural coniferous wood and are completely free of any synthetic and adhesive additives. The material does an excellent job of absorbing sounds, is able to drown out impact and airborne noises coming from neighboring apartments. When using a slab of this manufacturer with a thickness of 12 mm, it can increase noise insulation up to 23 dB, and a slab with a thickness of 25 mm - up to 26 dB.

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

Acoustic material "Zvukanet" for wallpaper is presented in the form of a sound-insulating 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 glued. It is offered in rolls of 14 m, 500 mm wide.

Green Glo belongs to high quality vibration and noise insulation materials, helps to absorb vibration and sound waves, can be used in combination with thin frame systems. During installation, it is laid as an interlayer between GVL or gypsum board. One 828 ml tube is enough for 1.5 square meters.

Use of Topsilent Bitex soundproofing membrane. The material is made with a thickness of about 4 mm, it is not limited to a certain value of the frequency range. During installation, it allows you to increase the sound insulation of the surface (wall or ceiling) up to 24 dB.

As for the sizes, there are two options:

Roll 11.5 m long and 0.6 m wide.
Roll 23 m long and 0.6 m wide.

Texound refers to an innovative development that allows you to create the thinnest, but at the same time, effective soundproofing wall, ceiling and floor systems. Experts consider it to be the best material for protecting against high frequency noise. The panels are offered as a heavy mineral soundproofing membrane. Distinctive characteristics are the large weight and the presence of viscoelastic properties, due to which effective sound insulation of the room is achieved - about 28 dB. The material is presented with a thickness of 3.7 mm, a width of 1.22 m, a roll length of 5 m.

The Ecotishina system from Zvukanet is a non-woven sound and thermal insulation material, in the production of which high-strength polyester fiber is used, which provides high-quality sound insulation of walls, floors and ceilings. It is actively used when double wall structures and partitions are installed. The material is supplied 40 mm thick, 0.6 m wide, roll length 10 m.

Use of soundproof panels Comfort. Plates are a reliable soundproofing material that absorbs impact and airborne noise. Installation is possible on walls, floors, ceilings. When properly installed, the sound insulation level rises to 45 dB. Available on the market in thicknesses from 10 to 100 mm.

Features EcoAcoustics. It is considered a popular modern sound and thermal insulation material, shown in the photo, which includes polyester fiber, which provides a high-quality finish to any surface. Raw material layers are connected without adhesive by heat treatment. Standard sheet thickness 50 mm, width 600 mm, length 1250 mm. The package contains material with a total length of 7.5 sq. M. Color choices are limited to shades of green, white and gray.

The sound insulation characteristics of PhoneStar include a high sound insulation value of about 36 dB, a multi-layer structure. With the help of this modern material, walls, floors and ceilings are sheathed.

Shumanet-BM is another brand of mineral panels made of basalt and used for the purpose of soundproofing a room. The sound absorption level fluctuates within the 0.9 coefficient. Supplied in packs of 4 slabs (2.4 sq.m.), 50 mm thick each. Panel dimensions are standard - 1000x600 mm.

Fkustik-metal slik is a modern soundproof membrane material. The two-layer structure includes polyethylene foam and a lead plate, which improves the acoustic performance of the room by up to 27.5 dB. Each layer has a certain thickness - 3 mm, 0.5 mm and 3 mm, respectively. Material dimensions - 3x1 m.

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

Highlights when creating a ceiling soundproofing

The best is considered to be a frame sound-absorbing system made of gypsum plasterboards with the use of special membranes. State-of-the-art materials and secure fittings guarantee optimum structural efficiency.

Ceiling soundproofing "Premium"

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

Installation work is carried out in the following sequence:

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

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

The difference is as follows:

ThermoSoundIsol layer with membrane material is not attached to the floor slab;
the structure of straight suspensions must be wrapped in a Texound-70 membrane. The finished soundproofing system "Economy" will be no more than 66 mm thick.

What difficulties arise during installation work

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

Stacking and fastening of materials is carried out at a height, therefore, at least two workers are required, and for the convenience of their movement, scaffolds will be needed, which must either be rented or purchased.
High-quality materials for noise insulation, offered by trusted manufacturers, will cost the same price as their subsequent decorative design.
If the soundproofing structure is exposed to moisture, then the risk of damage to the mineral wool boards increases, which can be avoided by choosing expensive and moisture resistant materials, for example, cork panels.

The problem of panel houses is excellent audibility. Even respectable and calm neighbors, who do not throw noisy parties and do not drill walls every weekend, cause inconvenience. A variety of noises penetrate through the dividing walls and slabs: loud conversation, the clatter of falling objects, and even the sound of footsteps and moving chairs. To create a quiet and comfortable environment in the apartment, soundproofing of the ceiling will be required. Let's find out how to make it yourself and what materials to choose for different occasions.

Choosing the level of protection

The effectiveness of the soundproofing structure will depend on several factors, including:

Selected insulation material. Each type has different indicators of noise absorption.
Layer thickness. Some of the latest generation of insulators provide a high level of noise protection even at low thickness. But for traditional materials, the principle works: the thicker the better.
The number and composition of the layers. Practice shows that combining many materials with different properties and creating a multi-layered "cake" gives the best results.
Topcoat type.

For an apartment with high ceilings, you can choose any type of soundproofing system, regardless of the thickness. The most effective will be a multi-layer structure that combines roll sound-reflecting materials, noise-absorbing plates and gypsum board or gypsum plasterboard. In this case, the ceiling will be lower by 7.5–12 cm.

For a room with low walls, sound insulation under a stretch ceiling is suitable. It can also be multi-layered, but in this case, thinner materials are used. As a result, the ceiling will drop by a maximum of 6 cm, the average is only 3 cm.

If the height of the ceiling allows, no one bothers to use a large-thickness frame structure, reinforced with gypsum board, in combination with a stretch ceiling.

Types of noise and features of its propagation in different houses

To fully understand the issue, you need to know that 2 types of noises penetrate through the ceiling into the room:

airborne, caused by vibrations of the air (talking, singing, music, crying, dog barking, etc.);
shock, resulting from mechanical impact on the floor (stamping, moving furniture, hitting the floor).

What are we soundproofing: our own ceiling or the floor of the neighbors upstairs?

From the point of view of efficiency, it is much better to equip the soundproofing of the floor of the apartment located above. If there is an opportunity to negotiate with neighbors, it will be cheaper to pay for the soundproofing of the floor in their home. Impact noise protection with this approach will be significantly higher. The methods of soundproofing the floor are described in detail in.

Sound insulation systems: frame and frameless

If it is decided to protect the floor slab from the bottom from noise, from your apartment, it remains to choose the type of system, which can be frame and frameless.

Wireframe

The frame version, when properly executed, provides more reliable protection than the frameless one. The design consists of a fairly large number of elements, therefore, it involves significant labor costs. But, despite the certain complexity of the installation, it is based on, which are known to every master.

Elements of the frame system:

metal guides forming a crate;
holding the frame;
sealing tape that prevents the transmission of sound through the profiles;
sound insulating materials - sound absorbing plates, shields, sound insulating panels or membrane in various combinations;
vibroacoustic sealant;
drywall, standard or thicker soundproofing, or gypsum fiber in 1 or 2 layers.

The thickness of the structure varies between 75-120 mm. The additional sound insulation index is 11–21 dB (excluding the sound insulating ability of the floor itself).

Modification of the frame system is also used when arranging a stretch ceiling, but in this case, instead of profiles, wooden slats with a thickness of about 2.5 cm are used.

It is the frame technology that allows you to protect the room from all types of noise, both airborne and shock.

Frameless

A frameless system is more often used under a tensioning web. But there is a separate variety of it, where the same drywall acts as a finishing layer.

With a stretch ceiling, the situation is as follows: a sound wave coming from the ceiling is reflected from the stretched film, reaches the slab again and bounces off again. There is a "drum" effect. Sound insulation in such a situation will eliminate this effect and protect against airborne noise, however, its effectiveness against shock is low.

Elements of a frameless system for a stretch ceiling:

soundproofing material - membrane, plates or panels;
glue;
dish-shaped dowel-nails;
tension cloth.

The second version of the frameless system consists of the following elements:

sandwich panels ZIPS (soundproof panel system) with special vibration mountings;
vibration-insulating pad;
sealant;
special fasteners;
finishing layer of drywall, screwed to the sandwich panels.

Additional soundproofing of the floor, provided by the structure with the use of ZIPS - 11-18 dB. Thickness - 55-133 mm.

Noise insulation materials

Consider the features of common sound-reflecting and sound-absorbing materials.

Basalt (mineral wool), polyester or fiberglass slabs. They have an excellent sound absorption coefficient - up to 85%. Effective against any type of noise. They are mounted, as a rule, by the frame method. The only drawback is the large thickness. Well-known brands - Rockwool Acoustic, Shumanet, Stopzvuk, Aku-Light.

Sound insulating membranes. They have a high density and small thickness - 2.5–14 mm. Due to their structure, they do not absorb noise, but reflect, allow achieving high-quality sound protection. The disadvantage is the high cost. The most famous representatives are Tecsound (self-adhesive ultrathin heavy membrane made of aragonite mineral), MaxForte (consisting of aluminosilicate fibers, a layer of one-component rubber), Fkustik-metal slik (foamed polyethylene and a 0.5 mm thick lead plate).

Soundproof panels. Due to their massiveness, multilayer structure, elastic-viscous consistency and free filler particles, both shock and sound energy are reduced. For example, SoundGuard's EcoSukoIsol has a seven-layer cardboard profile filled with quartz sand.

ZIPS. Sandwich panels of this system consist of gypsum fiber and mineral wool, equipped with vibration assemblies for fastening, mounted on special fasteners without a frame, plasterboard sheathed on top.

Cork. Natural cork material provides good sound insulation, but to achieve a significant effect, a thickness of several cm is required. When using a technical roll cork 10 mm thick, one layer will not be enough.

In addition to these materials, coconut coir, felt, liquid sound insulation and others are used for ceilings.

Additional methods of noise isolation

As already mentioned, the degree of protection of the room from extraneous sounds depends on the final sheathing of the ceiling. For these purposes, use:

increased density gypsum board, for example Giprok "Aku-Line", Knauf Diamant;
acoustic triplex - 2 weighted gypsum fiber sheets with increased moisture resistance (GVLVU), connected with a special sealant. The total thickness is 16.5 mm. From above it is sewn up with a finishing layer of gypsum board;
noise-absorbing boards Knauf Piano.

Installation of sound insulation using frame technology

Instructions for creating a frame noise insulation system for the ceiling:

The base surface is thoroughly cleaned and primed.
All holes and slots in the ceiling slab are filled with sealant. This will prevent airborne noise from penetrating through them.
A sound-absorbing mat or multifunctional membrane of the "Texound" type is glued to the ceiling.
Vibration suspensions are attached at a distance of 50 cm from each other.
The profiles for the frame are glued with sealing tape.

According to the standard technology, a frame is mounted, which is lowered relative to the ceiling surface by 5-15 cm, depending on the required thickness of the soundproofing layer.
Soundproofing material is placed in the cells of the frame.

Two layers of drywall or gypsum fiber.
Soundproof panel + layer of gypsum board or gypsum plasterboard.
GCR layer + heavy noise-absorbing membrane + another GCR layer.

The layers of the "pie" can vary, especially since new, improved materials are constantly emerging. You can spy on effective solutions for self-implementation on the websites of professional soundproofing companies.

Frameless installation of noise insulation

The standard sequence of actions for arranging a frameless system:

Ceiling cleaning, priming.
Bonding the selected sound insulator. These can be roll varieties, panels or slabs. Sticking starts from the corner, the material is pressed tightly.

Note! The adhesive is not applied over the entire surface of the panel, but only around the perimeter and in the center. Even the slightest gaps between the elements are unacceptable.

Additional fastening of the panels with dish-shaped dowel-nails (they are called "umbrellas" or "fungi"), which are located in the corners and in the center.
Stretch ceiling installation.

Important points

When planning to make ceiling soundproofing, you need to remember that:

the best results are obtained by a combination of several materials with different properties - sound-absorbing and sound-reflecting;
self-assembly is possible only with careful adherence to technology. It is enough to forget to glue the damper tape or lay the material loosely, and the required effect will not be achieved.

And a final recommendation: since soundproofing the ceiling is an expensive event, you should consult with a specialist before choosing a material and installation. Ask your questions in the comments and get a detailed answer. The subtleties of self-arrangement of soundproofing an apartment are in the video below.

In apartment buildings, it is often very difficult to achieve complete silence. Noises coming from the street and coming from neighbors are sometimes very disturbing and annoying. Soundproofing the ceiling in an apartment can partially solve this problem. But for your peace of mind, you can additionally make noise insulation of walls and floors. It also does not hurt to replace the old windows with plastic ones. And all this can be done by hand.

Effective soundproofing of the ceiling

All noises and sounds are divided into air and percussion. The former arise from air vibrations, with the mechanical interaction of objects. They can be heard even through sockets and cracks. And the second type of noise comes from the impact on the ceiling partition. It can be a stomp of feet, which is capable of shaking, not only the ceiling of the apartment from below, but also be heard on the upper floors. Therefore, when choosing soundproofing protection, it is imperative to take into account its effectiveness.

When choosing a material, consider sound insulation properties

Ceiling structures

To isolate the room from extraneous noise, an additional ceiling structure can be assembled. This could be:

suspended ceiling - a metal frame is attached to the ceiling using suspensions;
stretch ceiling - fabric or film material that is stretched around the perimeter using brackets;
false ceiling - a metal frame is sheathed with sheet materials, such as plasterboard.

It is important to provide a gap between the structure and the floor slab. Sound insulation will be placed in it with a dense layer.

Soundproofing methods

If you want to know how to soundproof the ceiling in an apartment, we offer several ways:

Plasterboard ceiling decoration

This method of soundproofing a room is simple, but quite effective. The air gap between the ceilings and the plasterboard sheets allows an insulating effect to be achieved. And filling it with a certain sound-absorbing material provides additional noise insulation from the side of the ceiling.

Plasterboard is fixed to the ceiling using special profiles

Installation of stretch ceiling - film or fabric

This method is most suitable for isolation from extraneous noise. But it is better to entrust such works to professionals, since an inexperienced person is unlikely to be able to pull the canvas efficiently.

It is better to entrust the installation of stretch ceilings to specialists.

Acoustic ceilings

The popularity of this method is growing, thanks to the use of special perforated fabric or acoustic panels. These innovative materials have excellent sound absorption properties.

Perforated acoustic panels are excellent at absorbing noise

Thermal insulation with a unique liquid material

This method will help to solve several problems at once: get rid of penetrating noise, insulate the room, and also protect it from moisture and condensation.

Insulation not only absorbs noise, but also allows you to insulate the room

Be sure to consider the specifications of your room. If the ceilings are high, give preference to acoustic tiles, but if they are low, insulate with mineral wool and sheathe with plasterboard.

Necessary materials

The following materials are suitable for soundproofing the ceiling in an apartment:

mineral and cellulose wool;
foamed glass;
expanded polypropylene;
cork panels;
coconut fiber;
flax fiber;
basalt slabs;
felt.

The technical characteristics of cork panels, coconut and flax fibers are much better. Accordingly, the price for these materials is higher. Therefore, the most popular are mineral wool, felt and basalt slabs.

Soundproofing and insulation of the ceiling with mineral wool

To complete the installation work, you will need the following:

dowels (length 60 mm);
self-tapping screws (drill 12 mm) and for fastening drywall (60 mm);
plasterboard sheets (thickness 12 mm);
profile: wall guide and ceiling bearing;
cross profile connector ("crab");
suspension is straight.

Tools and protective equipment

Before proceeding with the installation, it is necessary to prepare tools and protective equipment for safe work:

building level;
drill and drill (diameter 6 mm);
screwdriver;
scissors for metal or grinder;
hammer;
corner (90 degrees);
tape measure and pencil;
construction or office knife.

Protect yourself when laying the insulator. To do this, before performing work, it is recommended to put on a respirator, goggles and gloves.

After you have prepared everything you need for work, proceed to calculations, drawings and installation itself.

Goggles provide perfect protection with a snug fit around the eyes

Installation sequence

When performing soundproofing of the ceiling with your own hands, use a special multi-layer structure.

The installation sequence in this case will be as follows:

insulation of electrical wires - all wiring must be enclosed in a plastic corrugated sleeve and secured with clamps;
preparation of the ceiling for the application of an insulating coating - clean and level the surface;
glue over with the selected sound insulator and support, or fix with dowels;
fix the hangers of the profiles for the subsequent installation of gypsum plasterboards (at a distance of 60 cm);
lay an insulating material on the protrusions of the suspensions, while leaving a small gap, approximately 60-100 mm;
cladding the resulting structure with plasterboard;
then you can paint, plaster or wallpaper.

The described method is quite effective, but has a small drawback. Due to the thickness of the entire structure, the ceiling height is reduced by 15-17 cm.

Multi-layer technology on the ceiling

Noise insulation of walls and floors in the apartment

You need to know that by installing only a soundproof ceiling structure, you may not achieve the long-awaited silence. In residential buildings, sound is also transmitted through internal partitions. And this means that complete soundproofing of the walls, ceiling and floor in the apartment must be made.

Floor work

For soundproofing the floor, the floating screed method is used using soundproof dense material, for example, stone wool.

The floor must be leveled and cleaned beforehand.
Glue vibration damping pads to liquid nails around the perimeter of the room. Their height should not be lower than the future screed.
Set beacons according to the level, lay soundproofing material tightly. Cover the top with one layer of plastic wrap.
Make a dry floor screed on top. The mortar is mixed in a 1/3 ratio (cement / sand). Cover the base with it 2-3 cm.
Lay the reinforcing mesh, then add a layer of mortar for another 2 cm.
Align the surface along the beacons, then remove them.
Sand the floor with a float.
Cut off excess edge at the base of the walls.

"Floating floor" will improve the sound insulation of the room by 50%

It is important to know that the soundproofing of the floor and ceiling in the apartment is carried out after all work on the walls has been completed. Therefore, the processing of seams and wall joints is a preliminary stage in the process of dealing with noise. Acrylic mass is well suited for this, which has a unique property to fill all the space around it.

Noise insulation of walls

Soundproofing the walls is possible in three ways:

Buy roll sound insulation and stick it on the wall. Use vinyl wallpaper adhesive. This is the budgetary but least efficient way. The noise level will be reduced by 50-60%.

Soundproof plasterboard construction

Operating procedure:

Cement all cracks and holes.
Make a frame for laying the insulating material. Fasten the profile, 2 cm away from the wall. It is advisable to place a vibration isolation made of rubber or cork under it.
Install sound-absorbing material. It can be soft acoustic mineral wool or glass wool, which has a higher sound absorption coefficient. Semi-rigid slabs of the same materials are also used.
Screw drywall to the profile.
Glue the joints with a special mesh, putty on top.
Wallpaper or paint the walls.
