Ceiling soundproofing which system to choose. Soundproofing the ceiling in the apartment - modern materials
Do you want to protect yourself from noisy neighbors upstairs, but do not know how to soundproof the ceiling in an apartment? I will tell you about 4 methods of work that I have personally tested.
Types of work and their features
Let's deal with the following options for carrying out work:
- Insulation with Isoplat plates;
- Soundproofing with the use of a special mineral wool;
- Soundproofing with mineral wool for stretch ceilings;
- The use of Ekozvukoizol panels as a sound insulator.
Option 1: gluing Isoplat boards to the surface
To begin with, I'll tell you about the main advantages of Isoplat heat-insulating boards:
- Naturalness and environmental friendliness... Plates are made from softwood fibers by heat treatment and pressing. The composition contains no chemical additives and adhesives. This allows you to use this option in rooms for any purpose;
- Convenience... The material is made in the form of sheets of 2700x1200 mm. According to the parameters of the product, they coincide with ordinary drywall. If desired, they can be mounted on a metal and wooden frame;
- Choice of options... Sheets can be 8, 10, 12 and 25 mm thick. The most often 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 makes it easier to work with them;
- Smooth front surface... One side of the slabs is flat, which makes it easier to finish.
The cost of the slabs depends on their thickness. The price of an 8 mm sheet is 600 rubles, 10 mm - 700 rubles, 12 mm - 800 rubles, and 25 mm - 1,700 rubles.
This slab is ideal for soundproofing rooms with low ceilings. With its help, it is possible to qualitatively insulate the surface, while the ceiling height will decrease by only 15-20 mm. For work we need the following materials:
| Illustration | Material description |
 |
Plates "Isoplat" 12 mm thick... The quantity is calculated based on the area of the ceilings to be insulated. When buying, always take material with a small margin of 5-10%, since waste is inevitably generated during cutting. |
 |
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 both cheaper and do not transmit sound vibrations, as can be the case with options with a steel nail. Due to the low weight of the boards, plastic nails provide the required reliability. For work, use options with a length of 70-90 mm, no longer needed. If it is not possible to find such dowels, you can use a pressure washer and a regular quick-fix dowel 60 mm long. |
 |
Primer... Before gluing the soundproofing boards, the base must be primed. This is necessary to strengthen the surface and improve the adhesion of the adhesive. |
Tool for work:
- Puncher... Used for drilling dowel holes. Don't forget to stock up on boers required diameter and length. If the work is carried out in several rooms, there should be at least two drills, since in the process of work they wear out rather quickly;
- Brush or roller... Needed for applying a primer to the ceiling;
- Liquid nail gun... The standard version is used for sealants. Choose stronger designs, since the adhesive is quite thick and when it is applied to the gun, high loads are found.
- Ladder, table or deck... It is necessary to provide easy access to the ceiling. It is best to work with three people, so the structure should be such that three people can sit on it;
- Hacksaw for wood or jigsaw... Slabs can be cut using either a power tool or a conventional hand-held hacksaw. Choose a tool with a small tooth size to minimize damage to the ends when sawing.
The instructions for carrying out the work look like this:
| Illustration | Stage description |
 |
The ceiling is being prepared... If there was whitewash or other finishing on it, then 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 unreliable. |
 |
The ceiling is primed... The composition is applied over the entire surface in an even layer. The most convenient and fastest way to work with a roller. After processing, you need to wait until the soil is completely dry. 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 around the perimeter with an indent from the edge of 2-3 cm. |
 |
This is how the glue is applied in the middle... It is important to apply the composition to the entire sheet. You can do it as shown in the photo, or it can be done differently: in zigzags, in a chaotic manner, etc. The main thing is that the glue is not only at the edges, but also in the middle. |
 |
The first sheet is installed on the ceiling... You should start from any angle. The work is done by three people: two install and hold the sheet, and the third drills holes and installs the dowels. |
 |
Holes are drilled for fasteners... The distance between the dowels should be 50-60 cm. They are located both along the edges and in the middle of the sheet. In the process, observe the vertical position of the punch. |
 |
Dowels are inserted, and fastening is made... Everything is simple and quick here: first, the dowel is inserted all the way into the hole, then a plastic nail is hammered 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 next sheet is cut so that there is a gap of at least 20 cm between the joint. |
 |
This is what the result of the work looks like.... If there are wide gaps between the sheets, they need to be filled with polyurethane foam. In the future, the surface is putty 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 for drywall with special wool
This type of work involves the use of special mineral wool. Such materials for noise insulation have the following features:
- High sound and heat insulation performance... Mineral wool perfectly dampens sound waves and at the same time serves as a good insulation. If you need to insulate and soundproof the ceiling, then better option can not found;
- Large selection of options... Products can be both in the form of slabs and in the form of rolls. The thickness can be from 2 to 10 cm. The best option is 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, square meter material 50 mm will cost you 130-150 rubles.
To work, you need the following materials:
| Illustration | Stage description |
 |
Acoustic mineral wool... This is the main material we will be using. It is best to purchase sheet options with a thickness of 50 mm, if you need to put a layer of 100 mm, then you can just put two rows. |
 |
Frame accessories... This includes the following:
|
 |
Acoustic suspensions... This is the main difference between a conventional plasterboard ceiling construction and a soundproofing option. The elements are fasteners with a damper gasket, due to which sound vibrations from the ceiling are not transmitted to the structure. |
 |
Drywall... Usually 9 mm sheets are used for ceilings, but I advise you to purchase a 12.5 mm wall version. It will serve as an additional soundproofing layer, providing the best sound absorption performance. |
 |
Acoustic tape. Glued to the wall profile. Prevents sound waves from the walls from being transmitted to the ceiling structure. |
Tool for work:
- Puncher... For drilling holes in the ceiling and walls for fixing the frame;
- Screwdriver... In the process of constructing the frame, you need to tighten a lot of self-tapping screws, it is difficult to do this manually. The set with a screwdriver must have several attachments of the configuration you require;
- Construction knife... It can be used to cut both drywall and mineral wool. If you have a mineral wool of great rigidity, then it will be more convenient to use a special knife for thermal insulation materials;
- Level, tape measure and pencil;
- Stairs or other device for working on the ceiling.
Let's figure it out how to make ceiling soundproofing:
| Illustration | Stage description |
 |
The walls are marked for the guide profile... For this it is best to use laser level, but you can get by with the usual. The line must run at least 50 mm from the ceiling. Most often, mineral wool of this thickness is used, and the frame is much easier to construct. |
 |
Acoustic tape is glued to the base of the profile... Remove the protective layer from the material, gently press it to the surface and cut off in the right place. |
 |
... For this, dowels are drilled in the wall at the location of the mounting holes. Then the chopiks are inserted into the wall, and self-tapping screws are screwed into them or impact screws are hammered. |
 |
Suspensions are attached to the ceiling... They are located along the line of the main profile with a step of 50-60 cm. Fastening to the ceiling is done with dowels. |
 |
The main profile is attached to the suspensions... To do this, you must first set a certain position using a level, and then tighten the screws in the right places. |
 |
Mineral wool is laid 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 tightly packed, the entire ceiling is covered with mineral wool. |
 |
The surface is sheathed with plasterboard... Everything is done here in a standard manner. |
Option 3: noise insulation under stretch ceilings
If you have stretch ceiling, then you can use the option with mineral wool, but without the frame device. Let's go straight to the list of everything you need:
| Illustration | Stage description |
 |
Soundproof mineral wool... Both slab and roll option... The recommended thickness is 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 gaps of at least 100 mm must be made on the joints of the material. |
 |
Fastening for thermal insulation. The length should be 4-5 cm more than the thickness of the mineral wool. |
 |
Plastic clamps... They are needed to connect the 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, with its help the vapor barrier will be fixed. |
 |
Dowels with mushroom head. Please note that in addition to the cap, the fasteners have antennae protrusions. At their expense, the vapor barrier will be fastened in the mineral wool. Please note that no screws are needed. |
Tool:
- Puncher... 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, noise insulation on the ceiling in the apartment is attached as follows:
| Illustration | Stage description |
 |
Holes are drilled in the ceiling. Standard size mineral wool sheets - 60x100 cm. 5 holes are made for each element - four in the corners with an indent of 4-5 cm from the edge and one in the middle. The hole depth should be 1 cm deeper than necessary.
|
 |
The mineral wool is fixed... Installation of ceiling sound insulation is very simple:
|
 |
Do not press the material too hard when attaching.... The dowel should not tightly press the mineral wool against the ceiling. The exceptions are options for plates of high rigidity, they can be pressed strongly. |
 |
The entire ceiling is covered with a sound insulator... It is important to dock the elements well so that they fit snugly against each other and adjoin well to the walls. |
 |
Attachment of the vapor barrier membrane begins... Let's figure out how to do the work with your own hands:
|
 |
Fastening is carried out over the entire surface... The spacing of the fasteners is determined on site. It is important that the vapor barrier is tightly pressed against the mineral wool, if there is a sag somewhere - put another fastener. |
 |
The connections are held together... In our case, we used plastic clamps. They are pushed into the holes punched under them and tightened. The excess ends are cut off. After that, you can put a stretch ceiling, the surface is high-quality soundproofed. |
Option 4: noise insulation using Ekozvukoizol material
I like this option for its simplicity and versatility, since the material serves both as an insulator and as a ceiling decoration. The main features of Ekozvukoizol are as follows:
- Environmental friendliness... The products represent a cardboard profile filled with a special mineral filler. The material does not contain chemical components, it is completely safe. Another important advantage is vapor permeability, that is, moisture from the inside will evaporate without lingering in the structure;
- Strength. The material is very reliable and can withstand even significant loads without compromising the integrity of the elements. The Ekozvukoizol ceiling is much stronger than the plasterboard version;
- Simplicity mounting... You don't need to put rock wool under the frame. Noise insulation of the ceiling is carried out simultaneously with the surface cladding. This saves time and effort.
As for the cost, it ranges from 700 to 900 rubles per square meter. The thickness can be 11, 12 or 13 mm. The height of the elements is 1200 mm, there are two widths - 800 and 450 mm, the weight of the first - 18.5 kg, the second - 10.5 kg.
Materials for work:
| Illustration | Material description |
 |
Ekozvukoizol boards... The quantity is calculated by the area of the ceilings. Do not forget to add a small margin, as during the work it is necessary to cut elements and waste may form. |
 |
Special tape for ends... Used to glue cut ends to cover the surface and prevent the filler from spilling out of the cardboard profile. |
|
|
Frame accessories... This includes the following:
|
 |
Acoustic tape for wall profile... Used to create a soundproof barrier between the frame and walls. The number is determined by the length of the walls in the room. |
 |
Anti-vibration sealant. It is used for sealing joints and abutments of the structure to the wall. |
 |
Washer enlarged М5... It will be put on self-tapping screws in order to increase the pressing area and thereby increase the reliability of the fastening. |
Tool:
- Rotary hammer with a drill;
- Screwdriver with attachment PH2;
- Construction knife;
- Roulette, level and pencil;
- Sealant gun;
- Fine tooth hacksaw- for cutting sheets.
The process of soundproofing the ceiling looks like this:
| Illustration | Stage description |
 |
The line of attachment of the wall profile is marked... It is necessary to draw out the lower edge of the future structure. It is important to accurately mark the perimeter so that the plane is flat. |
 |
Soundproof tape is glued to the wall profile... Just unwind the material gently, place it evenly on the profile and press gently along its entire length. The tape is very easy to cut with an ordinary construction knife. |
 |
The guide profile is attached... The work consists of the following actions:
|
 |
Suspensions are attached... The process looks like this:
|
 |
The main profile is inserted into the guide... The elements are aligned, the hangers are bent as shown in the photo. Then, using the level, the position of the elements is checked. If necessary, corrections are made and the profile is fixed with self-tapping screws. The excess parts of the suspensions are simply bent up 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 trimmed to fit the size of the sheets. Each joint should fall on a profile, remember this simple rule. The easiest way is to fasten the crossbars using special crab fasteners. They are simply put on the longitudinal profile, after which a jumper is placed and self-tapping screws are screwed in. It turns out a reliable frame for a false ceiling made of Ekozvukoizol. |
 |
Fastening starts from the corner... Before installing each next sheet, a soundproofing sealant is applied to the joint. It is important that the compound 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. |
 |
Sheets are cut if necessary. The most important thing is to make accurate measurements and mark the element before sawing. Leave a 2 to 3 mm gap so that the sheet fits into place so you don't have to trim it further. |
 |
A special tape is glued to the cut ends... It is sold together with Ekozvukoizol and is needed so that the filler does not fall out of the cut areas, because the material inside has a honeycomb structure. |
 |
All joints are treated with a sealant... This is a very important part of the process, so remember to do it ahead of time. It is important not to cover the joint from the outside, but to fill it across the entire width. |
 |
The sheets are very neatly aligned before fastening... You must dock them so that you do not rip the sealant off the end. A composition should appear along the entire joint, this is a sign of a high-quality filling of the connection. After that, fastening is performed. |
 |
The joints along the perimeter of the walls are filled with sealant... The better you fill the voids, the better the soundproofing will be. Do not feel sorry for the sealant. |
 |
The finished ceiling is left until the sealant dries.... Then the excess composition is carefully cut off, the surface is putty. |
Conclusion
Ceiling soundproofing 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 any questions, ask in the comments below.
carrying out works
When arranging their apartment, the owners try to ensure the maximum comfort of living. Many of the modern buildings do not differ in good sound insulation (however, houses of the 80-90s also cannot boast of this). Therefore, certain measures are being taken to create soundproofing of the home. In this case, you need to pay attention not only to the walls, because sound insulation for the ceiling is also very important.
From theory to practice
The main indicator in this case will be the efficiency of sound absorption.
Note that all noises and extraneous sounds are divided into:
- air;
- drums.
Percussive sounds - arising from mechanical impact, air sounds - everything that is emitted: screams, loud music, barking of a dog. Therefore, when choosing, you should pay attention to the above in the first place.
Common methods
Undoubtedly the most popular method is overlaid materials.
In this case, the material becomes:
- polyurethane foam- block or sprayed onto the surface (the second option is considered one of the most effective;
- Cork;
- coir;
- mineral wool;
- All kinds of panels made of mineral and organic fibers.
Such a device is associated with additional work - in particular, with the installation of an auxiliary system. Systems can be of different formats:
- Hemmed(the metal frame is installed on the floor; the frame is sheathed with plasterboard sheets);
- (film or fabric coverings are stretched on special brackets);
Above the cassette ceiling
- (soundproofing panels for the ceiling are laid on the metal frame).
Cork
There are many fans of cork materials today. Sound insulation against impact noise with this material is excellent.
- By level, only 2.5-3 cm of cork material is replaced by 10-15 cm reinforced concrete slab and 10 cm of pine timber. The noise level with a 3 cm thick balsa wood is reduced by about 20-45 dB. Therefore, a single-layer 10 mm soundproofing flooring is not sufficient.
- It is assumed that a layer of technical cork of about 3-4 cm will be created, which is covered with insulation on top (if required) and sheathed decorative trim... In this case, the quality increases several times.
Professional sound insulators
The name speaks for itself - these materials are created in order to successfully absorb any noise coming from the room located above.
Mineral wool slabs
Excellent soundproofing characteristics are shown by the ceilings, which are made with mineral wool slabs. In this case, the sound absorption coefficient is about 85%.
The technology here is quite simple:
- The necessary frame structure is fixed to the rough ceiling, which is clogged with mineral wool slabs;
- Further, the frame is sheathed with plasterboard sheets;
- At the end, soundproof ceilings are finished with any desired material (applying putty, paint, wallpapering).
Advice! The method is quite effective, but it has one very serious drawback: in total, the thickness of the entire structure will reach 15 cm (maybe more). It cannot be said that it is best sound insulation ceiling, but installation of this type is the right decision, and the price is affordable.
Sound insulating sheets
At the professional level, soundproof ceilings are made with special canvases. What are the advantages of a branded foreign gasket over traditional mineral insulation that are used ubiquitously?
- Most of the materials belong to the class of slightly flammable and completely non-toxic, so they are used not only in residential premises, but also in public places: restaurants, bars, clubs, cinemas;
- These materials are very easy to assemble. It is enough to remove the protective layer and glue it to the prepared base;
- In terms of the European noise absorption classification, such soundproof ceiling panels correspond to the BFT class (the highest);
- The canvas is a membrane, the sound in which "sticks". It can be carried out from various materials: high-quality rubbers, felt and others.
- For the production of the membrane, felt is used, which is a good sound absorber;
- When the wave hits the ceiling, the polymer will bounce off the sound. But in the felt the remnants of the shock wave will be extinguished without reaching the room;
- Soundproofing materials for a ceiling of this type have a thickness of 2.5 to 14 mm, so they will not hide the ceiling space.
Plates Shumanet BM
In many construction and repair companies, sound-absorbing ceilings are installed using acoustic panels Shumanet BM. In the modern construction market, these boards are one of the best and highest quality materials for sound insulation.
Plates are widely used for finishing stretch ceilings in apartments, cottages and country houses.
- The manufacturer's instructions note that the material is absolutely non-combustible (a very important factor for many types of premises);
- The standard noise absorption coefficient is 0.9 NRC;
- Plates are subject to quality control in the installation companies.
Shumanet BM plates are fixed to ceiling tiles with the help of plastic "mushrooms". This ensures high-quality fixing of the plates in all conditions. After that, soundproof suspended ceilings or other types of products (hemming, tension) are mounted on the slabs.
Complex systems
In the Russian construction market, many companies offer customers the installation of an integrated soundproofing system, which includes 2-3-4 different materials.
- In addition, the material is assembled by many on their own. In this case, people resort to a combination system, i.e. a sound-absorbing membrane is mounted on top of the sound-absorbing plates. Such a system will have an extremely high sound absorption coefficient.
- Not so long ago, special plates appear in steel stores that can be installed over an existing ceiling system. Such soundproofing materials for the ceiling have a serious advantage: sound absorption of the noise that comes from the owner's premises occurs. Thus, the owners of this solution eliminate unnecessary noise and neighbors.
Dropped ceilings
Plasterboard installation
Sound insulation of a suspended ceiling provides for fixing to the rough surface of the hollow rack structure, which is then filled with sound-absorbing material. After that, a decorative coating is made. Sometimes soundproof gratings or perforated drywall are attached to the ceiling.
A frame of this type is mounted from a standard metal profile for plasterboard ceilings.
But there are some peculiarities here:
- The effect of sound absorption will be directly related to the size of the interior cavity of the ceiling, which is filled with the material. Therefore, it is necessary to calculate the distance from the floor slab to the outer cladding, taking into account the thickness of the sound-absorbing materials used. You need to understand that the device of such a system will necessarily lead to a significant decrease in the total height of the room, which will be very noticeable in ordinary apartments;
- The outer part of the structure is a diffuser, a membrane that retransmits sound vibrations, in particular impact noise when it is rigidly attached through the supporting frame to the walls and ceiling. To avoid this, during the installation process, it is necessary to avoid extreme hard contact. metal frame with walls (a gap is left) and a rough ceiling (soundproofing fasteners and linings are used). This ensures the sound insulation of the ceiling from impact noise;
Hangers "Vibrofix P"
- During the installation of the soundproofing structure, care must be taken to maintain the absolute tightness of the system. Even small, barely visible slots and holes will allow sound to pass through.
Conclusion
If you are planning to get the highest quality result, then it is recommended to pay attention to the cork, complex systems... But you need to keep in mind that such a device will be quite expensive financially.
To obtain a high-quality result at minimal cost, you can use mineral wool or glass wool, which is placed in the space between the rough and false ceilings.
Soundproofing the ceiling - video and photo of this process in a large number can be found on the internet. Installation of this type can be done both with your own hands and with the involvement of specialists.
Stretch ceilings are rapidly gaining popularity - they allow you to create perfectly flat surfaces with a high decorative effect. But they are not able to become a sufficiently effective barrier to the penetration of noise - the soundproofing qualities of stretched PVC or fabric cloth are small.
If the noise from the upper floors becomes a real problem, then before starting the conduct, you should take a comprehensive approach to the problem. This means that, along with the choice of decorative qualities of the future ceiling covering, it must be thought out and high quality sound insulation ceiling in the apartment under a stretch ceiling.
Today there are many materials that can create silence in an apartment, and they are quite suitable for ceiling mounting. Some of the acoustic insulators are quite popular and have been used for many years not only to reduce noise levels, but also to insulate surfaces, as they have the appropriate properties. In addition to them, completely new materials are also on sale, which are specially designed for effective sound insulation.
Soundproofing materials for the ceiling
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 the structure of the acoustic type, due to which the absorption of sound vibrations occurs. Naturally, if you install only such a canvas without additional noise insulation of the floor surface, the effect will be far from complete, and therefore it is recommended to mount the stretch ceiling in combination with acoustic materials.
Today, the following materials are used to protect apartments from extraneous noise coming from the upper apartments:
- Various types of mineral wool or modified sound and heat insulators based on it.
- Expanded polystyrene, regular and extruded.
- Cork sheets and slabs.
- Foam mats.
- Modern soundproofing material based on mineral base "Texound".
Whichever material is chosen for noise insulation, a prerequisite it is always a matter of preparing the ceiling surface for installation work and installing a frame for a stretch canvas, which will subsequently hide the structure of the soundproof "barrier".
Prices for various types of soundproofing materials
Soundproof materials
Ceiling surface preparation and frame installation
Installation of any sound-absorbing materials under the stretch ceiling can be carried out different ways- gluing, laying between the lathing guides or fixing with dowels - "fungi". In some cases, it is better to use two fixing principles, especially when the base of the ceiling does not have perfect evenness. For example, the plates glued or installed between the guides are additionally fixed with fasteners - "mushrooms".
Whichever soundproof 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 the sound insulation can be installed immediately. Such a surface does not require special preparation, and the painted layer will perform the role of a primer.
- In the event that the ceiling covering is damaged, it is better to completely or partially remove it.
- Then, the surfaces are brushed with a stiff brush to remove fine debris and dust that can interfere with the adhesion of the boards or cloths.
- Further, there is the surface of the ceiling and walls 100 ÷ 150 mm from their joint in 2 ÷ 3 layers. Each subsequent layer of the primer is applied only after the previous one has completely dried. It is very important to properly process the joints of the ceiling with the walls and corners, since it is in these places that spots of dampness and mold often appear. For priming, special formulations are used that have an antiseptic effect. Such a primer will create a stable film on the surface, which will not only protect against microflora foci, but will also promote good adhesion of materials.
After the surfaces are primed and dried, you can proceed to fixing the guide profiles around the perimeter of the room for mounting the stretch ceiling.
- For this, first of all, along the entire perimeter of the room, the height at which the guides will be mounted is beaten. This process is carried out using a building level and a painted line, with which a straight line is struck on the wall. Instead of a building level, it is better to use a laser level to mark the line, which will determine the border of fixing the profiles at once along the entire perimeter of the room.
- The next step is to cut the profiles to the desired size.
- Since the profile is metal and is a good conductor of noise, then before installing it, it is necessary to stick a sound-insulating tape on the side that will be adjacent to the wall.
The tape is usually already equipped with an adhesive layer, protected by a foil, which is removed only before installation.
- Further, the profile is pressed against the wall with the side with the glued tape and is fixed on it with self-tapping screws or dowels through the drilled holes.
Fastening is done with a step of 100 ÷ 150 mm. Such a frequent arrangement must be maintained, since a very large load will fall on these fasteners from both the mass and the tension of the web.
- Then, the places for the installation of lighting devices are outlined. For them, special platforms are prepared and fixed, for example, from a bar, on which the lamps will be fixed. The thickness of the timber is selected depending on the distance by which the stretch fabric will be lowered from the base base of the ceiling. The platforms should be at the same level as the profile installed on the walls, or provide the required distance from the canvas if the installation of recessed luminaires is planned.
- After that, the electrical cable is connected to the installation sites of the lighting elements. The cable must be securely fixed to the ceiling or to wooden elements - no sagging is allowed.
- Further, at the places where the lamps are installed, the fasteners included in the kit are installed so that after the web is tensioned, the auxiliary parts of the devices are under it.
Now you can proceed to soundproofing work. They may differ depending on the selected material.
Characteristics and technologies of installation of soundproof materials
Now, knowing how to prepare the ceiling for soundproofing and install the frame for the stretch ceiling, you can proceed to the materials. To determine the choice, you should consider their characteristics and installation methods.

Mineral wool materials
Basalt mineral wool is most often used for heat and sound insulation works both on ceilings and on walls. It has good performance characteristics and is the most suitable for residential applications of all similar fibrous materials.
But it is better in our case to take not ordinary stone wool - today improved types of this material are produced, and their names directly speak of their purpose. This, for example, "Shumanet BM" or "Shumostop" C2 and K 2.
- "Shumanet BM"
This material consists of basalt fibers and is characterized as sound absorber premium class. One side of the mats is reinforced with a layer of fiberglass, which makes the surface more rigid, and the inner porous layer is well protected. Such a rigid "cover" keeps the slabs intact and prevents them from deforming, and also does not allow small particles to enter the room through the perforated stretch fabric.
Packaging of Shumanet panels The characteristics of the sound-absorbing plates "Shumanet BM" comply with the requirements of SNiP 23 ÷ 03 ÷ 2003 "Protection against noise". The main ones are shown in the table:
| Parameter value | |
|---|---|
| Standard slab size, mm | 1000 × 500; 1000 × 600 |
| Plate thickness, mm | 50 |
| Density of material, kg / m³ | 45 |
| Number of plates in a package, pcs. | 4 |
| The area of the slabs in one package, m2 | 2.4 |
| Weight of one package, kg | 4.2 ÷ 5.5 |
| Package volume, m³ | 0.1 × 0.12 |
| Sound absorption coefficient (average), dB | 23 ÷ 27 |
| Flammability (GOST 30244-94) | NG (non-flammable) |
| Not more than 1 ÷ 3% |
The sound absorption coefficient was determined during special acoustic tests carried out in the laboratory of NIISF RAASN in Moscow. This material has a low percentage moisture absorption, therefore, it can be safely used in rooms with high humidity.
- "Shumostop"
Fiberglass panels "Shumostop" Another material for a soundproof ceiling covering is "Shumostop". It is produced in two varieties and is marked C 2 and K 2. Therefore, if sound-absorbing plates are selected, special attention should be paid to the marking:
| Name of material characteristics | Parameter value | |
|---|---|---|
| C2 | K2 | |
| Standard slab size (mm) | 1250 × 600 | 1200 × 300 |
| Plate thickness (mm) | 20 | |
| Density of material (kg / m³) | 70 | 90-100 |
| Number of plates in a package (pcs.) | 10 | |
| The area of the slabs in one package (m2) | 7.5 | 3.6 |
| Single package weight (kg) | 11 | 8.8 |
| Packing volume (m³) | 0.15 | 0.072 |
| Sound absorption coefficient average, (dB) | 26-27 | 20 |
| Flammability (GOST 30244-94) | NG (non-flammable) | |
| Partial immersion water absorption in 24 hours | No more than 2% | Not more than 3% |
- C2 is most often used for warming and soundproofing floors, since it is made from hydrophobic staple fiberglass.
- K2 is used for all surfaces. It is made from basalt fibers, and usually just such a "noise stop" is used for soundproofing ceilings.
Often these materials are used in combination, since C 2 has a higher sound absorption coefficient, and K 2 is less harmful to human health. Therefore, fiberglass plates are fixed with the first layer, and from above they are covered with basalt mats. When used in this way, they are able to reduce the noise level by up to 46 Db.
Installation of mineral wool sound insulation boards
Installation is carried out in the following sequence:
- If the sound insulator is planned to be laid between the guides of the crate, then first markings are made under it on the ceiling. Having determined the anchor points of the location of all elements, the lines are broken off along which the guides of the frame 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 plates.
For the frame can be used wooden bar or metal profile. The guides should not be of such a thickness that they lower them below the profile for the stretch fabric fixed to the walls.
If metal profiles are used for the lathing, then they must also be pasted over with a special tape, otherwise the effect of sound insulation will be reduced.
- The frame can be mounted directly to the ceiling or using hangers. They are fixed to the ceiling surface with dowels, and the crate elements are already fixed to them.
This option is acceptable if the apartment has a high ceiling and it is planned to lay a thick layer of soundproofing material. This should be foreseen in advance, even when fixing the profiles for the stretch ceiling.
- The next step is the installation of acoustic material slabs. They should fit as tightly as possible to the ceiling surface. If the sound absorber fits into the crate, it is recommended to fill it to its full thickness. The material should be laid between the frame elements.
- If the crate is not installed, then for a reliable connection noise-insulating ceiling slabs use one of the adhesives. It could be glue in the form of a spray that recently it is increasingly used for installation. Another option is cement-based or gypsum-based assembly glue.
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 plaster based glue. For installation on a painted surface, it is better to choose an adhesive spray that will perfectly fix the mats to the ceiling, without additional fixation with "fungi". It is best to spray the adhesive outdoors, such as on a balcony, and then immediately apply the mats and fix them to the ceiling surface.
- If glue based on gypsum or cement is used, it is necessary to additionally fix the mats with fixings - "fungi", for which through holes in the ceiling with a depth of 50 ÷ 60 mm are drilled right through the mats of the sound insulator.
Each of the mats will need to be used for fixing five six fasteners.
If a perforated canvas is used as a stretch ceiling, then in order to avoid the ingress of fibers from mineral wool into the air space of the room, it is covered from above with a vapor barrier film, and already from above it is fixed with fasteners - "fungi".
- The sound insulator, laid between the elements of the crate, is also closed with a membrane and fixed to the bars with the help of staples and a stapler, and to the metal profiles - with double-sided tape or - to the ceiling using "mushrooms".
After the lei, if used, is completely dry, you can proceed to the installation of the stretch ceiling.

Use of expanded polystyrene panels
For sound insulation of the ceiling surface, and different types expanded polystyrene, which is produced in a form convenient for installation in the form of plates of different sizes. Their thickness can be from 20 to 100 mm.
There are two classes of this material - common, unpressed expanded polystyrene (commonly referred to as polystyrene foam) and extruded. Their characteristics differ among themselves in most parameters:
| Comparative characteristics of 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 |
| Water vapor permeability, mg / m × h × Pa | 0,018 | - |
| Thermal conductivity in a dry state at a temperature of (25+ -5), W / (m × оС) no more | 0,028 - 0,03 | 0,036-0,050 |
| Sound absorption coefficient, dB | 23-27 | 42-53 |
| Static bending strength, 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 (combustible) | |
- Uncompressed Styrofoam
This class of material is marked with PSB-S, that is, self-extinguishing polystyrene foam, unpressed.
Polyfoam consists of granules of different sizes - the density of the material depends on this, which directly affects its soundproofing qualities.
For insulation of the ceiling, it is better to use polystyrene that does not high density, since the material is lighter in weight and lower in thermal conductivity. The density will be prompted by the marking itself - so, PSB-S 25 or 35 is well suited for ceiling mounting.
Styrofoam adheres well to the surface, provided that the glue is correctly selected for it. Usually, cement-based compounds, "liquid nails" or polyurethane foam... Fasteners - "fungi" are also used as an additional fixation to the surface of the ceiling.
- Extruded polystyrene foam
This material has a higher density, as it is made by extrusion - forcing the molten mass under pressure through molding nozzles.
Plates of this material often have a "locking" part of the tongue-groove or in the form of lamellas, which guarantees the creation of a seamless surface, and, in turn, increases the heat and sound insulation qualities of the layer being created. Expanded polystyrene with a thickness of 20 mm is able to dissipate impact noise and reduce the effect of it by 20 ÷ 27 dB, and this parameter increases with increasing thickness of the material.
For installation extruded expanded polystyrene the same formulations are used as for non-compressed foam.
The advantages of both types of expanded polystyrene for ceiling mounting include:
- Light weight, which guarantees a reliable fixing on the horizontal surface of the ceiling.
- Resistant to mold formation.
- Low thermal conductivity coefficient.
- Sufficiently high level of sound absorption.
The negative qualities of this material, for use in living quarters, can be called:
- The material is flammable, and during combustion it emits substances hazardous to human life with smoke. In addition, melting, it spreads, transferring fire to surfaces and objects close to it.
- Any expanded polystyrene does not tolerate ultraviolet radiation.
- With prolonged use, the material begins to decompose on its own, releasing hydrocyanic acid, hydrogen halides, nitrogen oxides and other hazardous compounds. To a greater extent, this phenomenon is subject to unpressed Styrofoam.
However, it should be noted that high-quality material, which includes flame retardants, is less flammable and self-extinguishing. Such expanded polystyrene certainly has a higher price. At first glance, it is difficult to determine the quality of the foam, therefore it is recommended that you familiarize yourself with the certificates of conformity, or purchase one plate and conduct experiments on it, which will determine the choice.
Installation of any type of polystyrene foam is identical. One of the selected adhesives is dotted onto its surface, and the board is pressed against the ceiling.
Then through holes are drilled, and through them fastenings - "mushrooms" are driven into the main ceiling. Usually, only two fasteners are sufficient for a slab planted with glue.
If this method is chosen, then it should be clearly understood that the ease of installation does not at all justify the very low sound insulation qualities of this material. The effectiveness of such noise protection is more than questionable.

Sound insulator "Texound"
"Texound" relatively recently appeared on Russian market and therefore has not yet managed to gain the due popularity, since not many people yet know the advantages of this material over other sound insulators. Its most important advantage, especially for apartments with a small 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 a modern soundproofer - "Texounda" "Texound", despite its small thickness, has a very high density, and is able to scatter and absorb sound waves of high intensity. Such a coating not only protects the room from unwanted noise from the outside, but also prevents the sound waves that are formed inside the apartment from leaving it.
"Texound" is produced in rolls or sheets, packed in polyethylene. The main characteristics are shown in the table:
In addition, Texound possesses the following qualities:
- Resistance to temperature extremes - it does not lose its original qualities even when freezing down to - 20 ° C.
- The elasticity of the material makes it similar to dense rubber.
- The material is impervious to moisture and has pronounced antiseptic properties, so mold will never appear on it.
- The operational period 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. Can have regular and self-adhesive surfaces, felt or foil padding:
| Name | Release form | Standard material dimensions in mm |
|---|---|---|
| "Texound 35" | roll | 1220 × 8000 × 1.8 |
| "Texound 50" | roll | 1220 × 8000 × 1.8 |

Installation of "Texound"
"Texound" can be fixed 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 soundproof 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" on the ceiling surface - The adhesive composition is applied to the surface of the material and the wall, then a pause is made for 14 ÷ 20 minutes, and only after that the Texounda canvas is glued to the ceiling.
- Since the material has a fairly large weight, 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 from help construction hair dryer or a gas burner.
- Some craftsmen prefer to glue the canvases with "Sealant" or "Liquid nails" glue.
- Self-adhesive "Texound" is very easy to mount, since the left layer on one side of it has already been applied - you just need to remove it protective film, press it to the surface and fix the material to the ceiling.
Convenient to use "Texound" with an already applied adhesive layer - After mounting on glue, the canvases should be additionally fixed with fasteners - "mushrooms", which are placed at a distance of 350 ÷ 500 mm from each other.
Additional fixation with dowels - "fungi" Second installation option
This option for the installation of a false ceiling includes several operations. They are carried out before fastening the stretch ceiling guides. Of course, this approach is only possible with a sufficient room height.
- The lathing is installed on the ceiling, mineral wool slabs are laid - according to the technology already described above.
- Then on the sheets of drywall, laying them on the desktop, the Texaunda canvases are glued.
"Texound" is pre-glued on drywall sheets - At the next stage, drywall with a sound insulator is mounted on the crate with self-tapping screws with a pitch of 100 ÷ 120 mm.
- The joints between the canvases are welded with hot air or glued with "Sealant".
- After completing the installation of drywall, you can proceed to the installation of the stretch ceiling guides.
The third option
- In this version, "Texound" is glued to the ceiling, as in the first method of installation, it is fixed with "mushrooms".
- After that, a frame made of a metal profile or a bar is mounted on suspensions or directly on the ceiling.
If a frame structure is required, then it can be attached after finishing the ceiling with texound - Further, one of the types of mineral wool is placed between its guides - it can be Shumanet or Shumostop.
- From above, it is advisable to sheathe the frame with plasterboard, and only then proceed to the operations for installing the stretch ceiling.
Noise insulation of the ceiling using acoustic foam rubber
Acoustic foam rubber is by far one of the most affordable and effective materials for soundproofing room surfaces, including the ceiling.
As you know, foam rubber has a porous structure that is capable of scattering vibration waves and absorbing vibrations. Vibration waves are especially noticeable in panel houses, since concrete walls have a 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 mats are very lightweight, so they can be glued to any surface using ordinary silicone or even double-sided mounting tape.
When using this material without additional finishing, you can choose a color scheme that will match colors of the entire interior, as 10–12 colors of mats are produced. Under a stretch ceiling, you don't have to think about the color scheme and get a more affordable price acoustic foam- white or gray.
The thickness, or rather, the height of the embossed pattern of the foam rubber can be from 25 to 100 mm. In addition, there are several relief patterns of the surface of the material, which also allows you to make a choice.
Foam rubber reliefs have their own names corresponding to the picture - these are "Wedge", "Pyramid" and "Wave" (egg tray). In addition, foam rubber elements are produced with a special shape, designed to neutralize the propagation of low-frequency sounds.
Acoustic foam rubber is not very popular for open use in an apartment, as it accumulates dust quickly enough. But it does not at all lose its soundproofing qualities even if it is covered with decorative material - the main thing is that the foam rubber fits snugly to the surface of the ceiling or wall. That is, for a stretch ceiling - this is a great option.
Installation of foam insulation
Fixing foam mats to any surface can be called the easiest of all installation works related to fastening soundproof materials. Foam rubber can be attached to heated silicone, spray glue, "Liquid nails" or double-sided assembly tape.
In the event that the mats are planned to be closed, for example, with drywall, you will have to make a frame crate, and the installation process in this version 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 with one of the selected adhesives. It is very important that the soundproofing material adheres tightly to the surface. The adhesive can be applied in spots or sprayed over the entire surface of the mat.
- Then, the foam rubber is firmly pressed against the ceiling and adheres to it for several seconds.
- Further, next to it, the next mat is mounted - and this is how the entire surface of the ceiling is filled.
- Then, on top of the foam rubber, in the grooves of its relief, crate elements are installed, at a distance of 550 ÷ 600 mm from each other - this parameter will depend on the width of the drywall sheet, since they should find their edges at half the width of the bar or metal profile.
- After installing all the guides, the electrical wiring is mounted, and the sheets are fixed on top of the crate
- Next, is the installation of the frame under the stretch ceiling.
In this case, drywall will serve as an additional layer of sound insulation.
Another, simpler and more affordable option, can be gluing foam rubber to the ceiling, and then immediately installing a frame for a stretch ceiling, installing platforms for lighting fixtures and fasteners for them.
If the goal is to isolate the ceiling from the penetration of external noise, then from the materials presented above, you can fully choose the one that will be the most affordable and according to the technology of self-assembly.
In conclusion, it should be noted that in order to achieve the maximum effect of soundproofing a room, it is necessary to cover with one of the acoustic materials in this room, including the walls and the floor, since the reinforcing belt transfers sound very well from one slab to another. By fixing the soundproofing boards only on the ceiling, you can only slightly reduce the noise coming from the top.
When it comes to soundproofing a ceiling, the first thing to think about is getting the best possible results for your money.
But for this you need to know the basic soundproofing principles, methods and understanding of sound processes, which the physics section is devoted to - acoustics... There are many soundproofing technologies and materials available, but only a few are suitable for a particular situation.
If you plan to do your own ceiling soundproofing, then find solutions that are inexpensive and easy to install ceiling soundproofing. The more knowledge you have, the more consciously you approach the question of how to soundproof the ceiling, the better the final result will be.
The soundproofing of the ceiling is based on the selection noise-absorbing materials and technical solutions at the place of installation in order to achieve noise reduction of impact, airborne, structural origin.
What is the difference between sound and noise? Sound, as is known from physics, is mechanical vibrations molecules of a substance under the influence of forces capable of creating changes in the position of molecules of a substance in one place and transfer this effect to neighboring molecules. This creates a sound wave that is perceived by the human auditory organs.
A sound wave is characterized by amplitude, frequency, phase, propagation speed. It is characteristic that the speed is almost independent of the wave frequency. Therefore, the human ear perceives sounds in the same order in which they are reproduced by the sound source. Otherwise it would be difficult to discern what is coming from the loudspeaker.
There is another effect of sound force on the hearing organs, when the threshold for the perception of sound frequencies in the range of 16-20000 Hz is exceeded, but the force of pressure on the eardrum of the ear depends on the volume level, measured in dB (decibels).
A value of 0 dB corresponds to a pressure of 20 microPascals, which determines the lower threshold of hearing, and 120 dB corresponds to the upper threshold, the short-term exposure to which is painless. Prolonged exposure to 80 dB loudness will cause hearing loss.
Loud sound protection in progress sound insulating materials for the ceiling. They absorb the wave, converting the vibration energy into heat. The sound dissipates, the intensity of the impact decreases. The phenomenon of refraction is taken into account in the manufacture of the material. It is known that when a sound wave passes from one medium to another, the following phenomena occur:
More often than not, these phenomena occur simultaneously. Diffraction phenomenon- the ability of a sound wave to bend around obstacles. The size of the wavelength is compared with the size of the obstructing barrier: if the wave is smaller, then it is reflected, and if, on the contrary, or is comparable to the size of the obstacle, then the sound wave is diaphragm. If, for example, this is a slit, then the wave bends around it too. Resonance, interference are also taken into account in the design of soundproof systems.
Phenomenon reverberation takes place in a confined space. Sound vibrations are repeatedly reflected from walls, ceilings, floors, and other objects. The final perception is distorted, causing discomfort. This is noise.
The concept is rather subjective not amenable to rigorous assessment. The concept of the term "soundproofing" used for indoor, and for cars use the term "Noise isolation"... Note that the noise generated by undefined sounds need not be loud. A quiet snoring coming from the next room is enough to induce insomnia.
Street noise during the daytime is not as perceived as if it occurs at night. For some, the noise does not cause discomfort, for others it interferes with doing something. Levels sound pressure on the tympanic membrane are most powerful with low-frequency vibrations. It is defined by the Sanitary Code SN 2.2.4 / 2.1.8.562-96... Table 3.
Soundproofing materials for ceilings
Appointment of noise insulation of ceilings- prevent the penetration of sound from the outside, absorb sound waves generated by sound sources inside the room.
It is logical to assume that effective way protection from these phenomena would be to limit the influence of the sources of the creation of sounds, which is not always possible to do, because not every neighbor can be negotiated, and the noise of the street cannot be regulated. So you have to look for soundproofing material for the ceiling.
Reverberation protection comes down to the proper placement of sound-absorbing materials for the ceiling, walls, as well as the use of interior means:
- curtains on the windows;
- upholstered furniture;
- bookshelves;
- acoustic screens;
- carpets on the floor.
Among modern soundproofing materials for ceilings, the following can be distinguished:
- MaxForte SoundPro is a roll-to-roll soundproofing of a new generation. Created taking into account theoretical developments in the field of building acoustics. With a thickness of 12 mm, it provides effective protection against impact and airborne noise. Maximum class "A" for sound absorption. Ideal for small apartments where every centimeter counts. No glue in the composition and chemistry. The material is completely non-flammable.
Suitable for soundproofing ceilings, walls and floors. It can be used in wireframe and frameless schemes. The rolls are not afraid of moisture, do not attract insects and rodents.
- MaxForte EcoPlita - basalt slabs made of volcanic rock, have excellent acoustic properties. Without smell. There are no slag and blast furnace waste impurities in the material.
It is used for soundproofing the most difficult objects: cinemas, recording studios, restaurants. High sound absorption coefficient αW at all frequencies (including low ones). Completely non-flammable material.
- MaxForte EcoAcoustic - polyester boards (acoustic sintepon). For maximum sound absorption, aerodynamic fiber placement is used during production. Material from homogeneous raw materials, does not emit harmful substances, without glue in the composition.
During installation, they do not crumble, do not generate dust and do not prick. To work with the material, no special clothing, gloves or a respirator are required. Suitable for allergy sufferers and asthmatics. Not afraid of moisture.
- Vibrostop Pro - vibration-isolating mount to eliminate impact noise. Allows to reduce vibrations passing to the profile and provide additional sound insulation of the ceiling and walls at a level of 21 dB.
- Sealant MaxForte - used for sealing seams, joints and holes. Does not transmit sound and vibration. High waterproofing properties. Contains mold and mildew inhibitors. High adhesion to all types of surfaces.
Also effective sound insulation the ceiling is made of acoustic panels. Let's start the choice with them.
Acoustic panels - soundproofing material for the ceiling
CFAB ™ Cellulose Panels- panels based on cellulose... Made from 65-75% recycled materials, an alternative to traditional synthetic fiberglass panels. Some foreign panels have a density of 1 lb / ft3 = lb / ft3. Which in terms of standard units will be 16.02kg / m3.
If you come across the designation of the density of panels in lb, then most likely these panels are from a foreign manufacturer. Here a brief description of CFAB ™ Cellulose Panels:
The sound absorption coefficient is characterized by a value from 0 to 1. The lower the value, the higher the reflectivity. A value of 0 is total reflection of the sound wave and 1 is total absorption. Coefficient from 0.4 and higher for sound-absorbing materials. They are used to protect against airborne noise (which is transmitted through the air). In addition to the sound absorption coefficient, there is a characteristic sound insulation index (RW), expressed in dB, which is used for structures (prefabricated systems).
What density to use mineral wool for soundproofing the ceiling depends on the nature of the noise: if it is airborne noise, then a density of 70 kg / m3 and an absorption coefficient of 0.7-0.8 are sufficient, at a noise level of 25 dB a person feels comfortable. This applies to soft materials such as the CFAB ™ acoustic panel. With a thickness of 50 mm and a density of 48 kg / m3, the sound absorption coefficient reaches 0.9.
If it is necessary to improve the acoustics in the home theater room, then the noise insulation material for the ceiling is chosen taking into account the interior... Perhaps a few absorbing screens installed around the perimeter of the walls and on the ceiling will suffice. Stick the CFAB ™ or Echo Eliminator ™ panel directly to your wall or ceiling.
How to soundproof the ceiling and walls in a frameless way, see the picture.
What materials and tools do you need for do-it-yourself frameless noise insulation of the ceiling? If the ceiling is concrete, then the ceiling soundproofing device is performed gluing acoustic panels... You will need: metal scraper or brush, primer, putty, glue, measuring and cutting tools, protective equipment.
The order of work is as follows:
- Ceiling preparation. With a scraper or brush, remove the old cladding in places where it does not hold well. Then all cracks and cracks are putty, allowed to dry, then a primer is applied to the ceiling.
- Gluing panels. The borders of the panel are marked on the ceiling or wall, then a sealant "liquid nails" is applied to the back side of the panel, and glue is additionally smeared. Press the panel against the ceiling or wall and hold it for 5-10 seconds.
Advice. To rationally use the material, before soundproofing the ceiling, consider how many whole panels are needed. Gaps are left between the wall and the ceiling, so start gluing along the middle axis of the ceiling, so symmetry will be respected.
Installation of noise insulation of the ceiling frameless way they are made as an addition to a ready-made plaster ceiling or to a previously prepared and leveled concrete ceiling.
It is more difficult to achieve maximum soundproofing of the ceiling and walls from structural and impact noise... Structure-borne noise is generated in sewerage and water supply pipes, but this problem has already been practically resolved in modern construction: plastic pipes successfully act as a damper in the path of propagation of sound waves.
As for the impact noise transmitted along the obstructing structures, everything is much more complicated here. We need to solve the problem comprehensively. The best soundproofing of the ceiling from such sounds is suspended ceiling systems: slatted ceilings, plasterboard ceilings, stretch ceiling.
Suspended systems - the best ceiling sound insulation
There are suspension systems that differ in the way the frame is attached and the types of suspensions (clips).
Consider a versatile suspension system that is suitable for both ceiling and walls.
Attention! Wall and ceiling GKL panels are separated by damping clips from the ceiling and wall.
I wonder how the stretch ceiling affects sound insulation with such a suspension system?
If you pull it in addition to this system, then more two layers of media of different density: canvas and air gap between ceilings. A sound wave, passing through an additional structure, will be refracted in 2 media and give each of them its energy. Stretch ceiling takes 80 -100mm of the ceiling height. You can assemble a plasterboard structure using special ceiling hangers for a wooden beam 50 x 50 mm.
Do-it-yourself ceiling soundproofing
Such a suspension is needed for assembly.
Installation of soundproofing of the ceiling begins with a marking. Here is an approximate diagram of how the suspensions and bars of the first row of gypsum boards should be located.
First, a crate is performed, then 19mm gypsum board is sewn to it, mineral wool is laid, and then a second insulating layer of gypsum board with a thickness of 12.5mm is sewn to the gypsum board. This is what a cake like this would look like.
Here the height of the additional structure will be 75 mm... Noise insulation on the ceiling (1), made with mineral wool (4), is in a multi-layer structure and protects against all types of noise: air, shock, structural.
If in this structure instead of gypsum plasterboard (1) there was a stretch ceiling canvas, then fastening the sound insulation to the ceiling (6) would complicate the work: the sheets of mineral wool would have to be glued to the old ceiling before installing the ceiling, but after installing the stretch ceiling, finishing will not be needed.
A source of noise in the bathroom more often sounds of working washing machine, the noise of water falling on the shower tray, the operation of the exhaust fan,
Soundproofing the ceiling in the bathroom will partially solve this problem. Can be glued to the ceiling sound absorbing material, cover it from below with a stretch ceiling - the problem of airborne noise will be solved.

If it is difficult to choose what kind of sound insulation is needed, consult with consultants from sales departments and other specialists. Unfortunately, it is possible to fully check whether the soundproofing of the ceiling helps, as well as to find out what the effectiveness of the soundproofing material is, can only be done by installing it. Testing the material by the seller in the presence of the buyer will not always be as effective as after final assembly on site.
Remember, soundproofing the ceiling is effective even when noise reduction by 5-10 dB is a good result, which reduces the level of exposure to the hearing aid by almost 2 times. In Table 3, the average daytime equivalent noise figure is defined at 40 dB, and the nighttime noise figure at 30 dB. This is what we should strive for.
