Material for soundproofing the ceiling and method of fastening. Soundproofing the ceiling in an apartment or house - how to make soundproofing materials with your own hands. Sound insulation installation technology

One of the disadvantages of living in apartments in multi-storey buildings is the excessive presence of extraneous noise. And even when renovations are not being done in the neighboring apartments, and the music is not blaring, unnecessary sounds still penetrate into the home. This problem can be solved by installing soundproofing, but another question arises here. Installation will take up useful space, which is already not much, so one option is fine sound insulation ceiling. This will protect the apartment from unnecessary sounds and save usable space.

Types of noise

structural - it is also called structural. Occurs from impacts on the walls, for example, during renovations or rearrangements in the apartment. It is transmitted through the structural elements of the building, i.e. through ceilings and walls;
acoustic – also transmitted through walls and ceilings, but arises from external sources and is initially transmitted through the air. This could be a loud conversation, music, etc.

The most unpleasant type is structural. And it is much more difficult to protect against it than against acoustic ones. The fact is that normal sounds transmitted through the air are partially muffled when they reach obstacles.

Structural ones, on the contrary, are transmitted much faster, because in houses, all load-bearing elements are interconnected. Moreover, a lot depends on the type of house. There are three main types of multi-storey buildings:

Brick is the most successful in terms of sound insulation. Thanks to the thick walls and different materials, the problem of sound insulation is not too acute.
Panel - has a particularly poor design. Thin concrete partitions perfectly transmit any sounds. Therefore, high-quality sound insulation is the only way to ensure silence in the apartment.
Frame - walls and ceilings are thicker than in panel houses. But, nevertheless, the sounds still travel well.

Thus, if the apartment is in a panel building, you will have to try hard to ensure peace and tranquility.

Soundproofing principle

The denser the material, the better sounds pass through it. Therefore, concrete or brick cannot provide protection against sound penetration. The noise-insulating material must have a porous structure and be soft - this allows it to dampen noise. The more heterogeneous the structure of the material, the better the acoustics are suppressed.

Their effectiveness is measured by absorption coefficient. It has a range from 0 to one. The higher it is, the better the material works.

For example:

brick – 0.04;
concrete – 0.02;
wood – 0.15.

So the usual Construction Materials They do not interfere with the penetration of noise at all. For this, the absorption coefficient must exceed 0.5 units.

In general, existing materials are divided into two types:

absorbent;
reflective.

Ideally, high-quality sound insulation should combine both types. This will guarantee protection against structural and acoustic noise.

In addition, there is another division according to rigidity:

hard - have the lowest absorption coefficient. Up to 50-60%, but their advantage is their compactness; such panels can have a thickness of 1-2 cm;
semi-rigid - medium option, has good absorption and low thickness;
soft - usually these materials have the most high efficiency– they are able to absorb up to 90% of sounds. But their disadvantage is their thickness. For example, one of the most popular representatives is mineral wool. Its minimum thickness is 5 cm, and the optimal thickness is 10 cm.

Thus, you always have to make a choice between saving space and effective sound insulation.

Classic materials

Nowadays there is a large selection of soundproofing materials on the construction market. However, there are those that are the most popular. Among them:

polystyrene foam - most often used for insulation, but at the same time, the material absorbs extraneous noise well. The main advantage is low cost and ease of installation. The main disadvantage is the large thickness of the material required to achieve the result, as well as the need for a finishing coating;
mineral wool is an effective non-flammable sound insulator, but its installation requires a frame structure and subsequent coating;
expanded polystyrene is a durable material that protects well from noise, but is highly toxic;
Self-adhesive soundproofing tapes - in addition to good heat and sound insulation properties, have another advantage - they are environmentally friendly.

The main disadvantage of classic materials is their thickness. For example, the same mineral wool can take up about 10 cm of room height. Therefore, when rooms have low ceilings, it is better to look for other options for protection from extraneous sounds.

Thin materials for ceiling soundproofing

"Shumanet" is a modern soundproofing material, available in rolls and slabs

Thin ones allow you to protect yourself from the penetration of various noises, and at the same time save useful space. Of course, they will not be able to isolate the room from noise 100%, but still, they are quite effective.

Popular materials:

soundproofing lining - in fact, it is a thin polystyrene foam film. Provides leveling of the base surface of the ceiling, insulation and sound insulation. The thickness of the material is about 5 mm, and this allows you to achieve a minimum sound absorption coefficient - about 20-30% of noise;
cork covering is finishing material, however, due to its technical properties it is an excellent insulation and sound insulator. Therefore, thin cork panels can not only decorate the room, but also protect it from noise;
noise block is another name for this material, loaded vinyl. Possesses high performance sound absorption, and at the same time pleases with its small thickness - it is only 2.5 mm;
soundproofing membranes – have high elasticity and a small thickness of 4 mm. At the same time, it is easy to install and effectively reflects sound waves. The installation process itself is extremely simple: a sheathing is mounted on the base ceiling, and then an insulator is attached to it. The only condition is that the canvas must be solid and smooth. Those. All joints must be taped. And the membrane itself is well tensioned;
Green Glu compound is a mastic that is applied to the finishing material. Typically used in conjunction with suspended ceiling systems such as plasterboard;
penoplex – also relatively new material. In fact, it can be called an improved version of polystyrene foam. Compared to it, it has greater strength and better technical characteristics. On the other hand, its cost is also higher. For effective insulation and sound insulation, it is required to use slabs with a thickness of 3-4 cm;
softboard - slabs based on natural wood. A big plus is the environmental friendliness of the material and mechanical strength. Can be mounted without a frame, and the thickness of the plates is from 1 cm;
“Shumanet” are mineral slabs based on basalt. They have a good price/quality ratio and have almost 100% sound absorption.

Rolled sound insulation "Texound"

This modern materials, which allow you to protect the room from unnecessary noise. When choosing, you need to take into account the technical characteristics, as well as the specific situation, since they all work differently.

Sources of noise

Before carrying out work on soundproofing the ceiling, it is necessary to understand where noise can enter the room from. As mentioned above, it comes in two types – structural and acoustic. From acoustic, sound insulation helps well ceiling surface. But to protect against structural damage, you will have to take care of the walls.

In addition, sources may be:

places where heating pipes pass;
sockets;
any technical holes.

It must be taken into account that any building shrinks over time. And this leads to the appearance of cracks in structural elements, which gives excess decibels free passage into the room.

Sound insulation laying technology

Regardless of the material chosen, the fundamental technology for installing sound-absorbing materials will be approximately the same. It consists of the following stages:

preparation of the base surface - the ceiling must be thoroughly cleaned of old finishes and checked for cracks and damage. Particular attention is paid to corners, ceiling and wall joints and seams between slabs. If cracks are found, they must be sealed;
then the surface is treated with a primer;
after this, sound insulation material is installed;
held final finishing ceiling.

In general, there are two points that you need to pay attention to when working:

the ceiling surface must be free of cracks;
Sound insulation must be installed according to the manufacturer's instructions.

Compliance with such rules guarantees that the goal will be achieved. In addition, if possible, it is worth combining various materials. This will allow you to achieve maximum effect.

Installation under a frame system

Most often, mineral wool or polystyrene foam is placed under the suspension systems. The installation technology consists of the following stages:

preparation of the base surface;
installation of the profile system frame. In this case, all frame elements that come into contact with the walls or ceiling must be taped with a special tape. If this is not done, between the base surface and finishing so-called bridges will appear. And this will significantly reduce the effectiveness of sound insulation. Because sounds are transmitted very well through these bridges;
then the insulator is laid. Depending on the material chosen, it can either be glued or fixed with dowels. In any case, it is important to ensure that it fits tightly to the ceiling and does not sag anywhere. Particular attention is paid to the joints - there should be no gaps.

Installation without frame

If you plan to use dense materials, for example, penoplex insulation, then it can be mounted without any problems without a frame. As with any material, careful preparation of the base surface is necessary. Then the material itself is mounted:

foam boards are glued to the surface;
if necessary, additional fastening is done with anchors;
all joints are sealed with polyurethane foam or other sealant;
After the sealant has hardened, all excess is cut off and the seams are sealed with special tape.

Thus, today the construction market offers a wide variety of materials for sound insulation. In addition to classic polystyrene foam and mineral wool, there are modern solutions that can solve the problem of effectively absorbing extraneous sounds and at the same time saving usable space. And the installation of such coatings is quite simple and can be done by hand.

Do you want to protect yourself from noisy neighbors from above, but don’t know how to soundproof the ceiling in an apartment? I will tell you about 4 methods of carrying out work that I have personally tested.

Types of work and their features

Let's look at the following options for carrying out work:

Insulation with Izoplat boards;
Sound insulation using special mineral wool;
Sound insulation with mineral wool for suspended ceilings;
Using Ekozvukoizol panels as a sound insulator.

Option 1: gluing Izoplat boards to the surface

To begin with, I’ll tell you about the main advantages of heat and sound insulating boards “Izoplat”:

Natural and environmentally friendly. The boards are made from coniferous wood fibers by heat treatment and pressing. There are no chemical additives and adhesive compositions. This allows you to use this option in premises of any purpose;
Convenience. The material is manufactured in the form of sheets 2700x1200 mm. The parameters of the product are the same as conventional drywall. If desired, they can be mounted on a metal or wooden frame;

Selecting options. Sheets can have a thickness of 8, 10, 12 and 25 mm. The most commonly used option is 12 mm, but if you need to insulate the ceiling in a room with a high noise level, then it is better to use elements 25 mm thick;
Light weight. A sheet with a thickness of 8 mm weighs 6 kg, 10 mm - 8 kg, 12 mm - 10 kg and 25 mm - 20 kg. The lightness of the elements simplifies working with them;
Smooth front surface. One side of the slabs is flat, making it easier to finish.

The cost of the slabs depends on their thickness. The price of a sheet of 8 mm is 600 rubles, 10 mm - 700 rubles, 12 mm - 800 rubles, and 25 mm - 1700 rubles.

This board is ideal for soundproofing rooms with low ceilings. With its help, you can efficiently insulate the surface, while the ceiling height will decrease by only 15-20 mm. For work we need the following materials:

Illustration	Description of material
	Izoplat plates 12 mm thick. The quantity is calculated based on the area of the ceilings that need to be insulated. When purchasing, always take material with a small margin of 5-10%, since cutting inevitably generates waste.
	Liquid Nails. With their help, the primary fixation of the elements will be carried out. You can use almost any option, the main thing is that the composition is suitable for wooden and concrete surfaces. One package is enough for about 3-4 square meters.
	Dowels for thermal insulation. It is best to use options with a plastic nail. They are cheaper and do not transmit sound vibrations, as can happen with options with a steel nail. Due to the light weight of the slabs, plastic nails provide the required reliability. For work, use options with a length of 70-90 mm, no longer needed. If you cannot find similar dowels, you can use a pressure washer and a regular quick-installation dowel 60 mm long.
	Primer. Before gluing soundproofing boards, the base must be primed. This is necessary to strengthen the surface and improve the adhesion of the adhesive composition.

Tool for work:

Hammer. Used for drilling holes for dowels. Don't forget to stock up on drills required diameter and length. If the work is carried out in several rooms, there should be at least two drills, since during the work they wear out quite quickly;

Brush or roller. Needed for applying primer to the ceiling;
Liquid nail gun. The standard version for sealants is used. Choose stronger designs, since the adhesive composition is quite thick and when applied to the gun there are high loads.

Ladder, table or flooring. It is necessary to provide convenient access to the ceiling. It is best to work with three people, so the design should be such that three people can sit on it;
Wood saw or jigsaw. You can cut slabs using either a power tool or a regular one. hand hacksaw. Choose a tool with a small tooth size to minimize damage to the ends when sawing.

The work instructions look like this:

Illustration	Description of the stage
	The ceiling is being prepared. If there was whitewash or other finishing on it, it must be removed. If the surface has been painted and the paint adheres very firmly, then it is not necessary to remove it. The main thing is to remove everything that is not held securely.
	The ceiling is primed. The composition is applied over the entire surface in an even layer. The easiest and fastest way to work is with a roller. After treatment, you need to wait for the soil to dry completely. This can take from several hours to a day, it all depends on the temperature in the room and the type of composition used.
	Glue is applied to the first sheet. First, the composition is distributed in an even strip along the perimeter with a distance of 2-3 cm from the edge.
	This is how the glue is applied in the middle. It is important to apply the composition to the entire sheet. You can do this as shown in the photo, or you can do it in a different way: in zigzags, in a chaotic manner, etc. The main thing is that there is glue not only at the edges, but also in the middle.
	The first sheet is installed on the ceiling. You should start from any corner. The work is carried out by three people: two install and hold the sheet, and the third drills holes and installs dowels.
	Holes for fasteners are drilled. The distance between the dowels should be 50-60 cm. They are located both along the edges and in the middle of the sheet. During operation, ensure the vertical position of the hammer drill.
	Dowels are inserted and fastening is made. Everything here is simple and quick: first, the dowel is placed all the way into the hole, then a plastic nail is driven in with a hammer.
	The following elements are attached. Everything is done in the same way as in the first case. There is one caveat - the transverse joints of the elements should not coincide. Therefore, each subsequent sheet is cut so that there is a discrepancy of at least 20 cm between the joints.
	This is what the result looks like. If there are wide gaps between the sheets, they need to be filled with polyurethane foam. IN further surface puttied and painted or finished in any other way.

This material is also suitable for walls and floors, so you can soundproof all surfaces if you wish.

Option 2: insulating the frame under plasterboard with special wool

This type of work involves the use of special mineral wool. Such soundproofing materials have the following features:

High sound and heat insulation performance. Mineral wool perfectly dampens sound waves and at the same time serves good insulation. If you need to insulate and soundproof the ceiling, then better option can not found;

Wide range of options. Products can be either in the form of slabs or in the form of rolls. The thickness can be from 2 to 10 cm. The best option- 50 mm, this is usually enough for high-quality insulation;

Fire resistance. Mineral wool does not support combustion, which allows it to be used in rooms with high fire safety requirements;

Availability. The cost of mineral wool is low; a square meter of 50 mm material will cost you 130-150 rubles.

The following materials are needed for work:

Illustration	Description of the stage
	Acoustic mineral wool. This is the main material we will use. It is best to purchase sheet options with a thickness of 50 mm; if you need to lay a layer of 100 mm, then you can simply lay two rows.
	Frame components. This includes the following: Main and guide profile; Self-tapping screws for fastening the structure; Dowel-nails for fixing to walls and ceilings.
	Acoustic suspensions. This is the main difference between the conventional design plasterboard ceiling and a soundproofing option. The elements are fasteners with a damper gasket, thanks to which sound vibrations from the ceiling are not transmitted to the structure.
	Drywall. Typically, 9 mm thick sheets are used for ceilings, but I recommend purchasing a 12.5 mm wall version. It will serve as an additional soundproofing layer, providing the best quality sound absorption.
	Acoustic tape. Glued to the wall profile. Prevents sound waves from the walls from being transmitted to the ceiling structure.

Tool for work:

Hammer. For drilling holes in the ceiling and walls for fastening the frame;
Screwdriver. In the process of constructing the frame, you need to tighten a lot of screws; it is difficult to do this manually. The screwdriver kit must include several attachments of the configuration you require;

Construction knife. It can be used to cut both drywall and mineral wool. If you have very hard mineral wool, then it will be more convenient to use a special knife for thermal insulation materials;

Level, tape measure and pencil;
Ladder or other device for working on the ceiling.

Let's figure it out how to soundproof a ceiling:

Illustration	Description of the stage
	The walls are marked for the guide profile. For this, it is best to use a laser level, but you can get by with a regular one. The line must be at least 50 mm from the ceiling. Most often, mineral wool of this thickness is used, and constructing the frame is much easier.
	Acoustic tape is glued to the base of the profile. Remove from material protective layer, gently press it to the surface and cut it in the right place.
	. To do this, drilling is done in the wall at the location of the mounting holes for dowels. Then the choppers are inserted into the wall, and self-tapping screws are screwed into them or impact screws are driven into them.
	Suspensions are attached to the ceiling. They are located along the line of the main profile in increments of 50-60 cm. Fastening to the ceiling is done using dowels.
	The main profile is attached to the hangers. To do this, you must first use a level to set a certain position, and then tighten the screws in the right places.
	Mineral wool is placed in the frame. The sheets are carefully tucked into the cells, and the ends of the hangers, bent to the sides, serve as fixation of the material. It is important to lay the sound insulator as tightly as possible so that there are no gaps between the sheets.
	The finished surface looks like this: the sheets are arranged tightly, the entire ceiling is covered with mineral wool.
	The surface is covered with plasterboard. Here everything is done in a standard manner.

Option 3: sound insulation for suspended ceilings

If you have a suspended ceiling, you can use the option with mineral wool, but without a frame. Let's go straight to the list of everything you need:

Illustration	Description of the stage
	Soundproofing mineral wool. Both slab and roll versions are suitable. Recommended thickness - 50 mm. The ceiling height should be sufficient so that you can lower the level by 7-10 cm.
	Vapor barrier membrane. Used to protect insulation. When calculating the quantity, do not forget that at the material joints you need to make overlaps of at least 100 mm.
	Fastening for thermal insulation. The length should be 4-5 cm greater than the thickness of the mineral wool.
	Plastic clamps. Needed to connect vapor barrier sheets to each other. Instead of clamps, you can use a special double-sided vapor barrier tape, but it is not available in all stores.
	Rondol. This is the name of the pressure washer; it will be used to fix the vapor barrier.
	Dowels with mushroom head. Please note that in addition to the cap, the fastener has antennae-like protrusions. At their expense, the vapor barrier will be attached to the mineral wool. Please note that no screws are needed.

Tool:

Hammer. And a drill of the required diameter and length;
Hammer- for driving nails into dowels;

Knife- for cutting mineral wool and vapor barrier material.

In this case, sound insulation on the ceiling in the apartment is attached as follows:

Illustration	Description of the stage
	Holes are drilled in the ceiling. The standard size of mineral wool sheets is 60x100 cm. There are 5 holes made for each element - four in the corners with an indentation of 4-5 cm from the edge and one in the middle. The depth of the hole should be 1 cm deeper than necessary. In order not to constantly control the drilling depth, wrap a piece of electrical tape or adhesive tape around the drill, this will be an excellent guide.
	Mineral wool is being fixed. Installation of ceiling sound insulation is very simple: A soundproofing mat is applied to the surface; In the right place, a mushroom dowel is inserted through the mineral wool; The fastener is inserted into the ceiling; A nail is driven in to secure the element.
	When attaching, do not press the material too hard. The dowel should not press the mineral wool tightly against the ceiling. The exception is options for slabs of high rigidity; they can be pressed firmly.
	The entire ceiling is covered with soundproofing. It is important to join the elements well so that they press tightly against each other and adhere well to the walls.
	The installation of the vapor barrier membrane begins. Let's figure out how to do the work yourself: You need to start from the wall. Holes are made in the membrane for dowels; A rondole is placed on the dowel, after which it is inserted into the mineral wool. Due to the antennae, the fasteners reliably hold the vapor barrier.
	Fastening is carried out over the entire surface. The fastener spacing is determined on site. It is important that the vapor barrier is pressed tightly against the mineral wool; if there is sagging somewhere, install another fastener.
	Connections are held together. In our case, plastic clamps were used. They are pushed into the holes punched under them and tightened. Excess ends are cut off. After this, you can install a suspended ceiling; the surface is well insulated.

Option 4: sound insulation using Ecozvukoizol material

I like this option for its simplicity and versatility, since the material serves both as an insulator and as a ceiling finish. The main features of Ecozvukoizol are as follows:

Environmental friendliness. The products are a cardboard profile filled with a special mineral filler. The material does not contain chemical components and is completely safe. Another important advantage is vapor permeability, that is, moisture from the inside will evaporate without being retained in the structure;

Strength. The material is very reliable and can withstand even significant loads without compromising the integrity of the elements. The ceiling made from Ekozvukoisol is much stronger than the plasterboard version;
Simplicity installation. You do not need to lay mineral wool under the frame. Sound insulation of the ceiling is carried out simultaneously with surface covering. This saves time and effort.

As for the cost, it ranges from 700 to 900 rubles per square meter. Thickness can be 11, 12 or 13 mm. The height of the elements is 1200 mm, there are two width options - 800 and 450 mm, the weight of the first is 18.5 kg, the second - 10.5 kg.

Materials for work:

Illustration	Description of material
	Ecozvukoizol slabs. The quantity is calculated based on the area of the ceilings. Do not forget to add a small margin, since during the work you need to cut elements and waste may be generated.
	Special tape for ends. Used to seal cut ends to cover the surface and prevent filler from spilling out of the cardboard profile.
	Frame components. This includes the following: Main and wall profile; The hangers are straight; Self-tapping screws for fastening; Dowel-nails for fixing the wall profile.
	Acoustic tape for wall profile. Used to create a soundproof barrier between the frame and the walls. The quantity is determined by the length of the walls in the room.
	Vibration isolating sealant. Used to seal joints and junctions between the structure and the wall.
	Enlarged washer M5. It will be put on self-tapping screws to increase the pressing area and thereby increase the reliability of fastening.

Tool:

Hammer with drill;
Screwdriver with PH2 attachment;
Construction knife;
Tape measure, level and pencil;
Caulking gun;
Fine tooth hacksaw- for cutting sheets.

The process of soundproofing a ceiling looks like this:

Illustration	Description of the stage
	The wall profile fastening line is marked. It is necessary to draw the bottom edge of the future structure. It is important to accurately mark the perimeter so that the plane is level.
	Soundproofing tape is glued to the wall profile. Just carefully unwind the material, place it evenly on the profile and gently press along its entire length. The tape is very easy to cut with a regular construction knife.
	The guide profile is attached. The work consists of the following actions: Points are marked and holes are drilled for dowel-nails; Dowels are installed. They should enter the surface until the cap rests against the profile; The screw is driven in with a hammer; there is no need to tighten it. If you need to remove the dowel, the screw is unscrewed with a screwdriver.
	Suspensions are attached. The process looks like this: First, lines are drawn on the ceiling where the profile will go; Holes are drilled along the lines for attaching hangers; The elements are fixed with quick installation dowels.
	The main profile is inserted into the guide. The elements are aligned, the hangers are bent as shown in the photo. Then, using a level, the positions of the elements are checked. If necessary, corrections are made and the profile is fixed with self-tapping screws. The excess parts of the hangers are simply bent upward so that they do not interfere with further work.
	Jumpers are attached. Since Ekozvukoizol sheets are heavy, the frame should be reinforced with jumpers. The distance between them is adjusted to the size of the sheets. Each joint must be on the profile, remember this simple rule. The easiest way to attach the cross members is with special crab fasteners. They are simply put on the longitudinal profile, after which a jumper is placed and screws are screwed in. This creates a reliable frame for suspended ceiling from Ekozvukoisol.
	Fastening starts from the corner. Before installing each subsequent sheet, soundproofing sealant is applied to the joint. It is important that the connection is completely filled with the compound, as shown in the photo. The picture also shows how the material is fixed: washers are put on the self-tapping screw.
	If necessary, the sheets are cut. The most important thing is to take accurate measurements and mark the element before cutting. Leave a gap of 2-3 mm so that the sheet fits into place and you do not have to trim it further.
	A special tape is glued to the cut ends. It is sold together with Ecozvukoizol and is needed to ensure that the filler does not spill out of the cut areas, because inside the material has a honeycomb structure.
	All connections are treated with sealant. This is a very important part of the process, so be sure to do it ahead of time. It is important not to cover the joint from the outside, but to fill it across its entire width.
	The sheets are very carefully aligned before fastening. You must butt them together so as not to tear off the sealant from the end. The composition should appear throughout the entire joint; this is a sign of high-quality filling of the joint. After this, fastening is carried out.
	The junctions along the perimeter of the walls are filled with sealant. The better you fill the voids, the better the sound insulation you will get. Don't skimp on the sealant.
	The finished ceiling is left until the sealant dries. Then the excess composition is carefully cut off and the surface is puttied.

Conclusion

Soundproofing the ceiling is a simple process; choose any of the four options and implement it in your apartment. The video in this article will help you understand the topic even better. If you have questions, ask in the comments below.

Noise is an irritating factor and therefore negatively affects not only the comfort of living, but also human health. Therefore, the desire of homeowners to protect themselves from extraneous sounds penetrating into the apartment is natural. This is achieved by performing sound insulation of enclosing structures separate rooms or housing in general.

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

Sources and characteristics of noise

Sound is a type of waves, vibrational movements of air or another medium that can be perceived by the human ear. The human ear perceives sound waves in the range of 16-20,000 Hz.

Noise is a collection of sounds that are not desirable for human perception in this moment, loud music or a cocktail of soft melodies is also noise.

Reality in the topic of noise protection of housing

Operating in R.F. SNiP 23-03-2003 “Noise Protection” defines a list of means that construction organizations should use to ensure noise protection for housing - from design to technical. But these measures, as a rule, are not enough to satisfy the wishes of homeowners, even if the noise level in the apartment does not exceed acceptable values. If actual conditions exceed noise standards, it often turns out that the builders’ failure to comply with SNiP requirements occurred due to objective reasons, for example, the housing under construction belongs to the economy class - equipping the building with the necessary noise insulation would lead to an increase in construction costs by approximately one and a half times.

One way or another, additional sound insulation of housing, in particular, sound insulation of the ceiling in an apartment, is a useful and sometimes necessary operation, which home owners most often do at their own expense.

Types of noise

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

One of significant classifications noise - by propagation medium:

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

A type of structural noise is impact - knocking.

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

Selecting the degree of sound insulation

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

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

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

Whether the ceiling bases in all rooms of the apartment should be insulated, or whether it should be limited to selective implementation, is up to the home owner to decide, especially in a situation where the ceiling height is only two and a half meters, and the insulation layer will take another seven centimeters, at least.

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

The effect of a noise insulation device can be measured using a special device - a sound level meter, by measuring the noise level in the room before starting work and after it is completed.

Types of soundproofing materials

The range of modern materials used for sound insulation of various types of ceilings is wide enough to make optimal choice for specific operating conditions.

Based on their operating principle, they are divided into sound-reflecting and noise-absorbing.

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

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

Important! Soundproofing material with heat-insulating properties also acts as insulation, which adds functionality to the installed coating without additional costs.

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

rolled - mineral wool, ecowool, penofol, staple fiberglass, foam rubber, felt in combination with polymers;
sheet - mineral wool, penofol, plasterboard, basalt cardboard, staple fiberglass, sand-laminated cardboard, soundproofing sandwich panels;
plastic – vibration sealants of various types;
decorative – cork sheets and panels, fiberglass, acoustic foam.

The list of materials can be continued for quite a long time, and the range is constantly updated with new developments with more high performance.

Functionality of anti-noise coatings

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

Structure-borne noise is transmitted through load-bearing structures, therefore, to neutralize them, the seams between the elements are filled with the following insulating materials - vibration sealants, silica fiber, fiberglass.

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

Important! The maximum effect is achieved by using a thoughtful combination of several of these materials, which best suit the existing noise impacts.

Designs of noise-proof coatings for ceiling bases

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

If the ceiling does not need leveling, or a decision has been made to level it using plastic mixtures, then after completion of this work a frameless installation of the soundproofing coating is performed.

If it is decided to level the ceiling using plasterboard, then a soundproofing layer is placed between the lintels of the frame on which the gypsum board is mounted. Such a sound insulation device is a related operation and, with the same leveling method, is called a frame one.

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

Frame method of soundproofing ceilings

There are many ways to perform sound insulation using frames. They differ in the materials of the frame, its design and location in the insulating shell.

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

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

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

Markings are made on the ceiling for a frame made of steel ud- and cd-profiles, taking into account the thickness of the insulator. Then a special vibrating strip tape is attached to the walls using vibration sealant, on top of which ud profiles are mounted.

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

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

Sealing of gypsum board joints is carried out with special gypsum-based compounds, for example. "Fugenfüller" produced by the Knauf company.

Finishing is performed on top of the installed sound insulation.

Frameless sound insulation of ceilings

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

The range of soundproofing materials offered today by manufacturers that can be used in a frameless manner is very wide. These include self-adhesive roll and sheet materials, sound-absorbing membranes, liquid sound insulators, and so on. But it should be borne in mind that the more advanced the technology, the more financial costs it will require. Let's consider one of the methods of frameless noise protection that does not require significant investment.

Doing your own ceiling soundproofing using the frameless method is technically easier than using a base. Let's consider a variation of the method described above with fastening the sound insulator with plastic snipes.

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

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

Then the element is covered with a layer of PVA glue, applied to the place and temporarily secured with fungi, slightly wedging them with baited anchors so that the sheet is pressed to the base. In this way, all soundproofing mats are attached to the ceiling.

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

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

Decorative noise protection

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

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

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

Important! When choosing a decorative insulation product, you should take into account that manufacturers attach more importance to the artistic design of such a material than to its functionality, and modern decorative noise protection materials do not always justify their price.

Conclusion

Despite the responsibility of the work that is carried out on such a visible basis, ceiling sound insulation, which is done by hand, is often more effective than that carried out by hired workers who allow minor deviations from the technology. Therefore, given the availability of technology, it is better to follow the principle “if you want it done well, do it yourself.”

The main gist of the article:

Protecting your home from noise is important.
Builders are not always to blame for insufficient sound insulation of housing.
You can make noise protection yourself.
Knowing the components of the noise factor will improve the efficiency of the final result.
The functionality of sound protection is more important than its artistic execution.

Content

The use of modern soundproofing materials makes it possible to achieve excellent sound insulation of the ceiling even with wooden floors. No house designs provide their residents with a 100% guarantee of noise protection. As a result, soundproofing the ceiling in an apartment is very important. It is quite possible to reduce the noise level to acceptable decibels if soundproofing protection is properly installed.

What is ceiling sound insulation

Sound absorption and sound insulation are not the same thing. The first parameter evaluates the degree of reduction in the energy of a sound wave when passing through ceilings or walls. And sound insulation is how much the pressure of a sound wave is reduced when it passes through obstacles in the form of ceilings. Ceiling sound insulation is assessed by residential builders using a specific coefficient (RW) in the frequency range from 100 to 3000 Hz. If RW equal to one, then the apartment is completely soundproofed. However, this does not happen.

Soundproofing the ceiling in an apartment

If we are talking about reducing the level of decibels penetrating into the apartment from external sources, then we talk about sound insulation. Isolating the entire room from penetrating external sound waves means properly installing noise protection on the walls, floor and ceiling. Soundproofing of the ceiling in an apartment is carried out using high-tech methods using new generation sound-absorbing materials.

Builders distinguish 4 types of noise that need to be dealt with:

Impact type noise. Occurs when a sound wave is created from impacts on the floor or partitions. In residential structures, this is the stomping of feet, noise from moving furniture, or the operation of a hammer drill or drill.
Airborne noise occurs when sound propagates through the air in conditions of poor sound insulation of walls and insufficient sound absorption by ceilings. It could be loud voices, music, dogs barking, birds singing.
Noise structural type occurs when there is resonance from high-frequency vibrations of air ducts and elevator shafts. Sound waves can travel very far.
Echoes, or acoustic noises, appear in an empty room.

From neighbors above

People living in the lower apartment suffer from impact and airborne noise coming from the floors above. Sound insulation from neighbors above is often so poor that if you put your ear to the walls, you can hear someone upstairs sitting in a chair. The most a good decision How to soundproof the ceiling from the neighbors above, it is considered the arrangement of soundproofing of the floors in the upper apartment. This creates a floating floor structure. It is made on the basis concrete screed with the addition of gypsum, which is laid on a layer of sound-absorbing mineral wool such as Akustik-stop.

From impact noise

Unfortunately, neighbors above do not always agree to the costs of creating a sound-absorbing layer on their floor, so soundproofing the ceiling from impact noise is done independently. The most in a simple way The device is considered to be a frameless system. It consists of two elements - a special sandwich panel, which is mounted directly on the ceiling, and a sheet of drywall, which must be attached to the panel at the end of the work. The installation process and the order of layers can be seen in the photo.

Under a suspended ceiling

System frame type is a conventional suspended ceiling with sound insulation made of gypsum fiber board or gypsum plasterboard. The advantages of this method include the fact that the surfaces are leveled, primed, all cracks and cracks are sealed, and only then the stretch ceiling is installed and soundproofed. When arranging sound insulation, it is necessary to place sound-absorbing materials overlapping, without leaving any gaps between them, otherwise all the work will go down the drain, and it will not be possible to achieve effective sound insulation.

In a house with wooden floors

Wood serves as a very good conductor of sound waves; in addition, over time, such floors begin to creak, so soundproofing the ceiling in a house with wooden floors very relevant. To ensure noise reduction, builders lay a layer of sound-absorbing material on the floor of the upper floor, fixing it with baseboards, and install sound-insulating stretch ceilings on the lower floor from several materials at once, stacked on top of each other in layers.

In a panel house

The situation is worst in panel-type houses due to the presence of a large number of gaps between panels and a low RW coefficient. Soundproofing the ceiling in a panel house alone will not help achieve an effective level of noise reduction; you must also try to isolate the walls and partitions in the apartment from external sounds to achieve the desired result.

Soundproofing materials for the ceiling in an apartment

Depending on the tasks, materials that can ensure silence in the apartment are divided into two types: soundproofing materials for ceilings and sound-absorbing. The effect of noise insulating materials is to reflect the sound wave back to the source, which is why they have a high density. These include sheets of plasterboard, fiberboard and chipboard.

Sound-absorbing materials disperse sound throughout their entire volume, reducing the number of decibels by approximately half. These include:

Soft materials based on felt, mineral wool, fiberglass. Their RW reaches 70%. They are produced in rolls with a variety of reliefs - in the form of pyramids, wedges, waves.
Compressed semi-rigid materials consist of fiberglass, mineral wool or polyurethane boards. Their RW reaches 75%.
Solid materials based on vermiculite or pumice. Their disadvantages include relatively low noise insulation.
Sandwich panels, which are a “layer cake”, inside of which there are liquid or soft sound insulators, and hard ones on the outside.

Soundproofing panels for ceilings

Soundproofing from neighbors above can be achieved using the following soundproofing panels for the ceiling:

Phonestar, which are wooden sheets with a mineral filler sandwiched between them. Their noise insulation index RW reaches 75%.
Akustik-stop – polyurethane fire-resistant panels with cells.
Akustik-metal sli - sandwich panels consisting of lead plates with polyurethane inserts. They have a high RW coefficient, reaching up to 80%, but their cost is high.
Comfort premium – MDVP sandwich panels filled with expanded polystyrene or glass-magnesite sheet.

Rolled ceiling sound insulation

You can ensure silence in the apartment not only with the help of bulky slabs or panels. Rolled ceiling sound insulation is gaining great popularity. This method involves gluing ceilings with special materials, which are high-density membranes made of non-woven polyester fibers. These include:

Topsilent bitex;
Polipiombo;
Tecsound (Texound);
Green glue (Green glue);
The acoustic will sound;
Eco-silence sounds.

Soundproofing a ceiling without a frame

Using special panels called ZIPS, frameless sound insulation of the ceiling is made. They are sandwich panels 120 mm thick, consisting of GPL, inside of which there is staple fiberglass. Each panel has special vibration units for fastening to the ceiling. After installing the ZIPS, it is necessary to complete the arrangement of sound insulation by attaching the plasterboard to the panel.

Soundproofing boards for ceilings

Providing sound insulation using soundproofing tiles for the ceiling is in great demand. The main advantages of basalt-based mineral slabs Shumanet-BM, EcoAcoustic and Knauf include the environmental friendliness of the material, which is safe for human health. Mineral slabs are resistant to burning, rotting, and moisture. Rodents do not eat them, fungus does not grow on them, and the service life of mini-slabs is comparable to the service life of the floor on which they are attached.

Self-adhesive sound insulation for ceiling

New innovative development - cheap adhesive strip made from specially treated polyethylene Izolontape - will help in creating self-adhesive sound insulation for the ceiling. This method of creating silence in the house is convenient, practical and will not cost much. The undoubted advantages of arranging sound insulation using self-adhesive tape relates to its environmental friendliness.

Cork on the ceiling for sound insulation

Plates made from crushed and compressed oak bark will only help improve the thermal insulation properties of the room, and cork sound insulation on the ceiling will be ineffective against external shock and airborne sound waves. In this way, you can only protect your neighbors from sounds coming from your apartment. Cork boards can only be used in combination with other soundproofing materials.

Which sound insulation is better for the ceiling?

How to choose the best system sound absorption for an apartment, if the materials that guarantee protection from shock and airborne sound waves are so diverse? The best sound insulation of the ceiling is achieved when all technologies were followed during the installation of slabs, sandwich panels or roll sound insulation, and the installation of soundproofing systems was carried out by professionals. If even the slightest gap remains between the panels or slabs, then we can say that all the work has been done in vain - after all, the sound will still penetrate the cracks and spread throughout the room.

Ceiling sound insulation price

Since the materials and scope of work to isolate the room from the penetration of external sounds are different, prices for soundproofing the ceiling in Moscow may vary. Sound-absorbing materials can be bought in an online store or ordered from construction market catalogs. The price of soundproofing the ceiling in an apartment is shown in the table:

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

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

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

Soundproofing materials for ceilings

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

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

Various types of mineral wool or modified sound and heat insulators made on its basis.
Expanded polystyrene, regular and extruded.
Cork sheets and slabs.
Foam mats.
Modern mineral-based soundproofing material "Texound".

Whatever material is chosen for sound insulation, prerequisite It is always necessary to prepare the ceiling surface for installation work and install a frame for the tension fabric, which will subsequently hide the structure of the soundproofing “barrier”.

Prices for various types of soundproofing materials

Soundproofing materials

Preparing the ceiling surface and installing the frame

Installation of any sound-absorbing materials under a suspended ceiling can be done in different ways - by gluing, laying between the sheathing guides or fastening with dowels - “fungi”. In some cases, it is better to use two fixation principles, especially when the base of the ceiling is not perfectly flat. For example, plates glued or installed between the guides are additionally fixed with fastenings - “fungi”.

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

If the ceiling has a high-quality painted surface, then sound insulation can be installed immediately. Such a surface does not require special preparation, and the painted layer will serve as a primer.
If the ceiling covering is damaged, it is better to remove it completely or partially.
Then, they pass over the surface with a stiff brush to remove small debris and dust that may interfere with the gluing of slabs or canvases.
Next, the surfaces of the ceiling and walls go 100–150 mm from their junction in 2–3 layers. Each subsequent layer of primer is applied only after the previous one has completely dried. It is very important to properly treat the joints of the ceiling with the walls and the corners, since these are the places where dampness and mold stains most often occur. For priming, special compounds that have an antiseptic effect are used. Such a primer will create a stable film on the surface, which will not only protect against the occurrence of pockets of microflora, but will also promote good adhesion of materials.

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

To do this, first of all, along the entire perimeter of the room, the height at which the guides will be mounted is marked. This process is carried out using a building level and a painted marking cord, which is used to mark a straight line on the wall. Instead of a building level, it is better to use a laser level to mark the line, which will determine the boundary for fastening the profiles along the entire perimeter of the room.
The next step is cutting the profiles to the required size.

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

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

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

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

Then, the installation locations for lighting fixtures are outlined. For them, special platforms are prepared and secured, for example, made of timber, on which the lamps will be fixed. The thickness of the beam is selected depending on the distance to which the tension fabric will be lowered from the base base of the ceiling. The platforms must be at the same level as the profile installed on the walls, or provide the required distance from the canvas if recessed lamps are to be installed.

After this, the electrical cable is connected to the installation sites of the lighting elements. The cable must be securely fastened to the ceiling or wooden elements– its sagging is not allowed.
Next, the fastening elements included in the kit are installed at the places where the lamps are installed, so that after the canvas is tensioned, the auxiliary parts of the devices are located under it.

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

Characteristics and installation technologies of soundproofing materials

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

Soundproofing materials MaxForte

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

Advantages:

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

MaxForte EcoAcoustic– material made of acoustic padding polyester (polyester fibers). Only primary raw materials are used in production. To maximize sound absorption, the material undergoes aerodynamic fiber laying technology.

Prices for MaxForte EcoAcoustic

MaxForte EcoAcoustic

Advantages:

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

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

Installation of MaxForte sound insulation is simple. The entire ceiling area is covered with material, and fastening can be done with ordinary dowel mushrooms.

Materials based on mineral wool

Mineral basalt wool is most often used for heat and soundproofing works both on ceilings and walls. It has good performance characteristics and is the most suitable for residential premises of all similar fibrous materials.

But in our case it is better to take something other than ordinary stone wool - today improved types of this material are being produced, and their names directly indicate their purpose. This is, for example, “Shumanet BM” or “Shumostop” C2 and K 2.

"Shumanet BM"

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

Packaging of Schumanet panels

The characteristics of sound-absorbing boards “Shumanet BM” comply with the requirements of SNiP 23÷03÷2003 “Protection from noise”. The main ones are shown in the table:

	Parameter meaning
Standard slab size, mm	1000×500; 1000×600
Plate thickness, mm	50
Material density, kg/m³	45
Number of slabs per package, pcs.	4
Area of slabs in one package, m²	2.4
Weight of one package, kg	4.2 ÷ 5.5
Packaging volume, m³	0.1×0.12
Sound absorption coefficient (average), dB	23÷27
Flammability (GOST 30244-94)	NG (non-flammable)
	No more than 1÷3%

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

"Noise stop"

Fiberglass panels "Shumostop"

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

Name of material characteristics	Parameter meaning
	C2	K2
Standard slab size (mm)	1250×600	1200×300
Slab thickness (mm)	20
Material density (kg/m³)	70	90-100
Number of slabs per package (pcs.)	10
Area of slabs in one package (m²)	7.5	3.6
Weight of one package (kg)	11	8.8
Packaging volume (m³)	0.15	0.072
Average sound absorption coefficient, (dB)	26-27	20
Flammability (GOST 30244-94)	NG (non-flammable)
Water absorption when partially immersed in water for 24 hours	No more than 2%	No more than 3%

— C2 is most often used for insulation and soundproofing of floors, since it is made from hydrophobic staple fiberglass.

— K2 is used for all surfaces. It is made from basalt fibers, and usually this “noise stop” is used for soundproofing ceilings.

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

Installation of mineral wool sound insulation slabs

Installation is carried out in the following sequence:

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

Can be used for frame wooden beam or metal profile. The guides should not have a thickness that would lower them below the profile for the tension fabric fixed to the walls.

If metal profiles are used for the sheathing, they must also be covered with special tape, otherwise the sound insulation effect will be reduced.

The frame can be mounted directly to the ceiling or using suspensions. They are fixed to the ceiling surface with dowels, and the sheathing elements are already attached to them.

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

The next step is the installation of slabs of acoustic material. They should fit as tightly as possible to the surface of the ceiling. If the sound insulator is installed in the sheathing, then it is recommended to fill it to its full thickness. The material must be laid spaced between the frame elements.
If the sheathing is not installed, then for a reliable connection soundproofing slabs with a ceiling using one of the adhesive compositions. It could be the glue in in the form of a spray, which Recently, it has been increasingly used for installation. Another variant - assembly adhesive on a cement or gypsum basis.

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

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

— If gypsum or cement based glue is used, it is necessary to additionally fix the mats with fastenings - “fungi”, for which through holes 50 ÷ 60 mm deep are drilled directly through the soundproofing mats in the ceiling.

Each mat will need to be used for fixation five six fastening elements.

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

The sound insulator, laid between the sheathing elements, is also covered with a membrane and secured to the bars using staples and a stapler, and to metal profiles with double-sided tape or to the ceiling using “fungi”.

After the lei, if used, has completely dried, you can proceed to installing the stretch ceiling.

Use of expanded polystyrene panels

To soundproof the ceiling surface, they are also used. different types expanded polystyrene, which is produced in a form convenient for installation in the form of slabs of different sizes. Their thickness can range from 20 to 100 mm.

There are two classes of this material - regular, unpressed expanded polystyrene (commonly called polystyrene foam) and extruded. Their characteristics differ from each other in most respects:

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

Unpressed Styrofoam

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

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

To insulate the ceiling, it is better to use polystyrene foam that has no high density, since the material is lighter in weight and has lower thermal conductivity. The density will be indicated by the marking itself - for example, PSB-S 25 or 35 is well suited for ceiling installation.

Polystyrene foam adheres well to the surface, provided that the glue is correctly selected for it. Typically, cement-based compounds, “liquid nails” or polyurethane foam. Fastenings called “fungi” are also used as an additional fixation to the ceiling surface.

Extruded polystyrene foam

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

Plates of this material often have a “locking” tongue-and-groove part or in the form of lamellas, which guarantees the creation of a seamless surface, and, in turn, increases the heat and sound insulation qualities of the created layer. Expanded polystyrene with a thickness of 20 mm is capable of dissipating impact noise and reducing its effect by 20÷27 dB, and this parameter increases with increasing thickness of the material.

For installation extruded expanded polystyrene The same compositions are used as for unpressed foam.

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

- Light weight, which guarantees reliable fastening to horizontal surface ceiling.

— Resistance to mold formation.

— Low coefficient thermal conductivity.

— Quite a high level of sound absorption.

The negative qualities of this material for use in residential premises include:

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

— Any expanded polystyrene does not tolerate exposure to ultraviolet radiation.

- At long-term operation the material begins to decompose on its own, releasing hydrocyanic acid, hydrogen halides, nitrogen oxides and other dangerous compounds. More susceptible to this phenomenon unpressed Styrofoam.

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

Installation of any type of polystyrene foam is identical. One of the selected adhesive compositions is applied pointwise to its surface, and the slab is pressed against the ceiling.

Then through holes are drilled, and through them fastenings—“fungi”—are driven into the main ceiling. Usually, for a slab mounted on glue, only two fasteners are sufficient.

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

Soundproofer "Texound"

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

Roll of modern sound insulator - "Texaunda"

"Texound", despite its small thickness, has a very high density, and is capable of scattering and absorbing sound waves of high intensity. Such a coating not only protects the room from unwanted noise from the outside, but also does not allow sound waves that are formed inside the apartment to escape beyond its boundaries.

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

In addition, Texound has the following qualities:

Resistance to temperature changes - it does not lose its original qualities even when frozen to -20 °C.
The elasticity of the material makes it similar to thick rubber.
The material is impervious to moisture and has pronounced antiseptic properties, so mold will never appear on it.
The service life of the material is unlimited.
"Texound" combines well with other heat and sound insulating materials, complements and enhances their effect.

"Texound" is produced in different sizes. May have regular and self-adhesive surfaces, felt or foil addition:

Installation of "Texound"

“Texound” can be attached to any base, be it concrete or wood, drywall, metal, plastic and other surfaces, the main thing is that they are prepared for its installation. Preparation takes place in the same way as for any other soundproofing material.

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

First installation option

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

Gluing "Texound" to the ceiling surface

The adhesive composition is applied to the surface of the material and the wall, then a pause is made for 14-20 minutes, and only after that the Texound canvas is glued to the ceiling.
Since the material is quite heavy, it is glued in small sheets.
The canvases are glued with an overlap of 40÷50 mm. After installation, an even cut is made along the overlap, then the edges of the sheets are aligned and welded together with warm-up using a hair dryer or gas torch.

Some craftsmen prefer to glue canvases with “Sealant” or “Liquid Nails” glue.
Self-adhesive “Texound” is quite easy to install, since a layer of adhesive has already been applied to one side of it - you just need to remove it protective film, press it to the surface and secure the material to the ceiling.

Easy to use Texound with an already applied adhesive layer

After installation with glue, the sheets should be additionally secured with fastenings - “fungi”, which are placed at a distance of 350÷500 mm from each other.

Second installation option

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

The sheathing is installed on the ceiling, and mineral wool slabs are laid using the technology already described above.
Then, Texound sheets are glued onto sheets of drywall, laying them on the work table.

"Texound" is pre-glued to sheets of drywall

The next step is to install the plasterboard with sound insulation onto the sheathing using self-tapping screws in increments of 100 ÷ 120 mm.
The joints between the sheets are welded with hot air or glued together with “Sealant”.
After completing the installation of drywall, you can proceed to installing guides for the stretch ceiling.

Third option

In this version, “Texound” is glued to the ceiling, as in the first installation method, and is fixed with “fungi”.
After this, a frame made of metal profile or timber.

If a frame structure is required, it can be attached after finishing the ceiling with Texaund.

Next, one type of mineral wool is placed between its guides - it can be “Shumanet” or “Shumostop”.
It is advisable to cover the frame with plasterboard on top, and only then proceed to the installation of a stretch ceiling.

Soundproofing the ceiling using acoustic foam

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

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

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

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

When using this material without additional finishing, you can choose a color scheme that will match color scheme the entire interior, as 10–12 mat colors are produced. Under a suspended ceiling you don’t have to think about color scheme and purchase more affordable acoustic foam - white or gray.

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

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

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

Installation of foam rubber sound insulation

Fixing foam rubber mats to any surface can be called the simplest of all installation works associated with fastening soundproofing materials. Foam rubber can be attached to heated silicone, spray adhesive, “Liquid nails” or double-sided mounting tape.

In the event that the mats are planned to be covered, for example, with plasterboard, you will have to make a frame sheathing, and the installation process in this option will consist of the following stages of work:

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

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

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

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

If the goal is to insulate the ceiling from the penetration of external noise, then from the materials presented above you can completely choose the one that will be most affordable in price and with self-installation technology.

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