Soundproofing the ceiling with your own hands, what materials. Soundproofing walls in an apartment using modern materials: types and self-installation

If you live in an apartment building and multi-storey building, then noise from neighbors cannot be avoided. To live comfortably in an apartment, you need to solve the main problem - to get rid of the neighbor's noise from above, because any movement or noise creates the biggest problem, what sound insulation to choose for the ceiling in the apartment and what sound insulation is better.

To live comfortably in an apartment, you need to solve the main problem - to get rid of the neighbor's noise from above, because any movement or noise creates the biggest problem

The quality of sound insulation leaves much to be desired in any type of house: brick, block, panel and even monolithic. All at home united by one problem– bad interfloor sound insulation floors. There is a separate section about soundproofing walls.

Noise from any source hits the ceiling, causing it, in turn, to vibrate and re-radiate noise into the apartment below. There is no escape from the mechanical impact on the interfloor partition.

How do ceiling soundproofing materials differ from each other?

For arranging a ceiling for sound insulation, materials with effective sound absorption are suitable. The arrangement of the ceiling is carried out using various methods, for each method manufacturers soundproofing materials came up with our own option.

But no matter how good the noise-reducing material is, it must have the following properties:

• Soundproof– the sound wave is not absorbed, but reflected. The sound wave does not rock the ceiling because the material has decent mass and internal loss.
• Sound-absorbing– the sound wave is absorbed using special pore channels. The material has a fibrous composition, there is friction in the pores, which has the function of inhibiting the sound wave.

For arranging a ceiling for sound insulation, materials with effective sound absorption are suitable.

The sound wave may not penetrate the material, but it will rock and generate secondary noise, so it is better to use a structure with sound-absorbing material inside and massive sound-proofing material on the outside.

When choosing a material, you need to pay attention to the following indicators:

• Material thickness.
• Sound insulation coefficient.
• Flammability.
• Certificate of absence of substances harmful to the body.

How to choose the right material?

The following materials are considered the most popular today:

• mineral wool. Material made from raw materials with non-flammable properties. It does not shrink and can be purchased in sheets 5 cm thick.
• mineral slabs- a convenient material to use, and the soundproofing method with cotton wool is considered the most effective. But only the ceiling in this case will become lower by 15-20 cm. So the increased thickness of the ceiling structure is not always good option, especially if the ceiling height is not pleasing.

Another disadvantage of cotton wool is the danger to human health. You will need high-quality insulation so that the material does not have negative impact per person.

• polyurethane foam. The sound-absorbing material has a tight grip, so it can protect against impact and airborne noise. The material absorbs not only noise from neighbors, but also sounds from your apartment. The disadvantage of polyurethane foam is its toxicity in case of fire. Therefore, such soundproofing arrangement is considered dangerous.
• sealing self-adhesive tape. This material is made from environmentally friendly raw materials and perfectly retains heat in the house.

High-quality insulation will be required so that the material does not have a negative impact on humans.

A good option is the use of heat and sound insulating panels made from environmentally friendly pine wood fiber.

There are alternative materials for soundproofing the ceiling. For covering the ceiling, for example, cork and foam sheets are used. Even with the advent of more modern materials, the love for cork cannot be changed.

But cork sound insulation is only suitable if your neighbors above have a concrete screed or laminate, and cork only saves you from impact noise. The screams of children, loud music, barking dogs - will be accessible to your hearing with cork sound insulation.

Reed tiles and foam glass can be used as soundproofing materials. For sound insulation they are sometimes used natural material: coconut fiber, peat, flax tow.

3 most successful ways to soundproof ceilings in an apartment

Even with good quality and the effectiveness of sound-absorbing material, the technological process of installing the structure is of paramount importance in understanding the physical processes of acoustics. There are no soundproofing materials for acoustics - There are soundproofing structures.

If the design is incorrect, the material will be of no use, so you need to choose effective method soundproofing ceilings and competently approaching the technology of installing a noise-reducing frame.

Today, ceilings can be soundproofed in different ways: using soundproofing boards, using thermal insulation composition or suspended structure. Each method has its pros and cons, and is applicable in a specific case. To achieve a noise-reducing effect, the following conditions must be met:

The most popular method of soundproofing a ceiling is using soundproofing material. Basalt wool, cork, polyurethane foam block or coconut fibers are used under drywall. The ceiling structure can be made in three versions:

• False ceiling made of plasterboard with a metal frame.
• with a film or fabric covering, which is stretched over special brackets.

Any of these options is installed according to the following scheme: installation of a vibration-isolated structure or an independent frame, then any sound-absorbing material, which is sheathed with plasterboard or hidden under an acoustic stretch ceiling.

NEW! An example of soundproofing a stretch ceiling with your own hands

When soundproofing a stretch ceiling, the main task is to fill the empty space between the floor slab and the stretch ceiling with a special sound-absorbing material, which:

1. Provides maximum absorption of noise entering the room from neighbors
2. Will dampen the suspended ceiling so that it does not resonate
3. Creates a favorable acoustic environment in the room and muffles noise entering the room

Sound insulation of a stretch ceiling implies high requirements for the environmental safety of the material, since when installing the canvas, holes remain through which harmful substances into a living space.

The optimal sound-absorbing material is MaxForte EcoAcoustic– white hypoallergenic polyester fiber boards or SoundPRO(thin 12mm new generation material). Both materials are environmentally friendly and do not contain harmful phenol-formaldehyde resins.

MaxForte EcoAcoustic

MaxForte SoundPRO

EcoAcoustic and SoundPRO differ in thickness, 50 mm and 12 mm, therefore, if there is no limitation on the thickness of sound insulation, EcoAcoustic is used, if you need to make it “thinner,” then SoundPRO is used.

Both materials are mounted in the same way:

1. A stretch ceiling baguette is installed (what the canvas will be attached to next)
2. Either MaxForte EcoAcoustic slabs or MaxForte SoundPRO rolls are fixed to the prepared ceiling surface (floor slabs). Fastening is carried out using ordinary dowel mushrooms.
3. After the ceiling surface is completely covered with sound-absorbing material, the stretch ceiling itself is installed.

The advantage of this method is that it saves height, since EcoAcoustic or SoundPRO fills the empty space between the floor slab and the suspended ceiling, thereby not taking away the height of the room.

Step-by-step guide: Soundproofing plasterboard ceilings

This method is popular among people who plan to install sound insulation with their own hands. Plasterboard slabs are easy to install; you may not even have any construction skills. This method does not require the use of a specific material; various soundproofing materials are suitable: mineral wool, polyurethane foam blocks, cork, coconut fiber, etc.

Do-it-yourself frame ceiling soundproofing performed according to the following scheme:

Soundproofing the ceiling is a whole system - “ layer cake", in which each "layer" performs its own task.

1. A frame is assembled from a conventional ceiling metal profile (for example, KNAUF 60x27),
   this is the future “skeleton” of sound insulation: what all other layers will be attached to.
2. The frame is attached to the ceiling using VibroStop PRO vibration suspensions. Their task is to break the rigid connection between the floor slab and the metal frame, and along the perimeter the profile guides are attached to the wall through 2 layers of damper tape (through which the drywall will later come into contact with the wall). As a result, vibrations (and sound is, first of all, vibration) will not transfer to the new plasterboard ceiling. More to the point in simple words, then the task of VibroStop PRO is to remove the impact noise that arises from stomping, falling objects, and the grinding of furniture on the floor of neighbors above.
3. Special acoustic plates are installed inside the mounted frame MaxForte ECOstove-60 they have a maximum class “A” for noise absorption, they remove airborne noise: screaming, crying, loud TV or music.
4. Next, GVL sheets (gypsum fiber sheet) are attached to the metal profile. All sheet joints must be coated with vibroacoustic silicone non-hardening sealant.
5. The last finishing layer is gypsum board sheets (plasterboard sheet). They are attached to the gypsum plasterboard, and the joints of the gypsum plasterboard and gypsum plasterboard are made staggered.

Tricks and secrets of sound insulation for suspended ceilings

Stretch ceilings provide a lot of advantages for the use of any soundproofing materials.

According to experts, a suspended ceiling is more effective in soundproofing a suspended structure. Acoustics are leveled out in this case thanks to the main feature of a stretch ceiling - sound damping in a soft texture. The suspended ceiling serves as a resonator.

If you decide to install a suspended ceiling yourself, then the sound insulation will be the same as for a suspended structure or a plasterboard ceiling. The frame is made of slats or a metal profile, a special material is glued into the resulting cells, and finally the fabric is stretched onto special brackets.

Stretch ceiling effective in houses where builders used floor screeds.

Manufacturers are trying to simplify the technological process of installing a stretch ceiling, and now you can purchase acoustic material with a perforated surface. The new canvas has special micro-holes through which noise is neutralized more effectively.

An affordable and popular method is covering the ceiling with mineral wool slabs. It has been proven that such material can absorb up to 90% of noise, and installation of the structure is simple.

Ceiling installation with mineral wool slabs consists of special design installations, in the cells of which noise-insulating material is placed. After the frame is filled with cotton wool, the structure is sheathed with plasterboard. A smooth surface can be painted, plastered, or wallpapered.

You can install a suspended ceiling yourself, how to do it? Installation instructions are the same as for soundproofing plasterboard ceilings:

• The space for the frame is marked.
• The suspended structure is assembled using slats or hangers.
• Soundproofing boards are installed in the resulting cells: mineral wool or fiberglass.
• The soundproofing material is hemmed with a decorative coating.

Installation of a suspended ceiling with mineral wool slabs can be done in another way:

If you have settled on a suspension system, then it is most logical to use cotton wool; installation of polystyrene foam is also allowed. Only Styrofoam cannot be glued, over time it will move away from the ceiling, forming an empty space.

The suspended ceiling structure not only protects from noise, but also hides any unevenness, giving the ceiling a very beautiful appearance.

How else can you achieve results?

One way to solve the problem of soundproofing the ceiling is to install a “floating” floor in the apartment above. If you have good relations with your neighbors, then the simple technology has an excellent noise-absorbing effect.

The floor is covered with polyethylene foam in the form of granules, then covered with technical cork. The resulting structure is filled with a concrete solution, and after drying, the floor covering is installed.

You can use a rolled substrate with a polyethylene foam base as floor sound insulation or use compositions based on polymer fibers.

Ceiling soundproofing cost

The construction services market offers more and more new products. Many companies can install not just a specific ceiling, but an entire comprehensive soundproofing system that will use different types material.

Prices for soundproofing work depend on the type of surface, installation option and level of noise reduction. For example, if you are planning to install an acoustic suspended ceiling, you will have to pay 240-600 rubles per square meter.

Most inexpensive option soundproofing— installation of a two-level ceiling structure made of plasterboard. The cost of the work will depend on the method of sound insulation and the choice of material.

The price for soundproofing a turnkey ceiling will cost on average 1,500 rubles per square meter. If soundproofing is needed to create a special room, for example, to build a recording studio, then the cost of soundproofing work will increase.

The ceiling is the main area in the apartment through which noise penetrates. The problem of “noise from the neighbor above” can be solved by the method of partial sound insulation: installing a soundproof suspended ceiling structure.

But soundproofing the ceiling will not always help get rid of the problem; most likely, you will need to protect the walls and floor from noise and sounds penetrating into the room from all sides.

Video instructions

Even the most imperturbable person can be enraged if you constantly pester him with annoying noises. Alas, living conditions in panel houses are such that soundproofing the ceiling in an apartment is not a whim, but a harsh reality. We offer you an overview of modern materials with current prices and useful photos, which will allow you to choose the best option for you and save as much as possible more nerve cells.

Criteria for materials

• environmental safety - no harmful substances during operation;
• layer thickness - the thinner the better;
• moisture resistance - the ability of a material to be used for a long time in conditions high humidity;
• noise absorption coefficient is the main indicator; the higher it is, the more preferable the choice seems;
• weight - this indicator determines the way in which the ceiling in the apartment will be soundproofed: if it is large enough, then a special frame will have to be built for installation.

What materials are there?

All modern materials, actively used for soundproofing the ceiling in an apartment, can sufficiently prevent the spread of noise waves in all directions. This means that after installation, not only will you no longer hear the active kitchen conversations of your upstairs neighbors, but they will also stop hearing your no less active ones. However, it’s not just about the kitchen and loud conversations, is it?

Mineral wool

• low cost;
• good efficiency;
• frame installation method.

Perhaps the most common option, which has received popular recognition due to the successful combination of low price and good level of noise absorption. In terms of this indicator - up to 85% - there is simply no equal to mineral wool among materials that are equally affordable in cost.

However, you have to pay for the opportunity to save in time spent: in order to install mineral wool in a city apartment, you must first equip the frame.

Someone will say, just think, can this somehow scare you? But the point is not the complexity of installation, but the precious centimeters that this very frame takes away from the final height of a particular room.

Add to this the considerable thickness of the layer of mineral wool itself - and you get a completely bleak picture for an expectedly low apartment in a panel or brick building.

Mineral wool is most often supplied in rolls.

Price it fluctuates within 800-1000 rubles per roll 18 square meters.

You can also read about the use of mineral wool for soundproofing the ceiling in an apartment with a suspended ceiling in our other article.

Basalt slabs

• affordable price tag;
• high noise absorption;
• frame installation method;
• good moisture resistance.

Essentially, in the form of basalt slabs we have the same mineral wool, compressed for greater convenience for end consumers. Of course, unlike roll options, such slabs are much easier to install on the ceiling, but still, to soundproof the ceiling in an apartment, you first need to build the same frame on which the material itself is then fixed.

The thickness of basalt slabs is similar to the thickness of mineral wool, which means that the problem of losing centimeters of height remains relevant even if this option is chosen.

Price : 850-110 rubles per package 4.32 square meters.

Glass wool

• low price;
• high noise absorption rate;
• poor moisture resistance;
• low level of security.

Glass wool is often used to soundproof the ceiling in an apartment, but in terms of the ratio of advantages to disadvantages, this modern material still cannot be considered the best option.

Judge for yourself: in rooms with high humidity - and this is the kitchen and bathroom - glass wool can swell and crumble, releasing substances harmful to humans into the space. The fiberglass used to make this material can potentially cause irritation when in contact with the skin - would any parent in the world allow such a threat to the health of their child in his own apartment?

In addition, the use of glass wool on the ceiling of an apartment often threatens problems with overheating of the wiring, which also entails serious consequences.

Price - from 600 rubles per roll 15 square meters, but we emphasize that this is an extremely impractical soundproofing material, inferior to alternative solutions in all respects.

Cork

• high cost;
• impeccable sound insulation;
• thin layer;
• high level of security;
• environmental friendliness;
• non-frame installation method.

In all respects, it is an ideal modern material for use in soundproofing the ceiling in an apartment. Does not require the creation of a special sheathing, is elementary in installation, friendly both in environmental and in practical terms- can be successfully used even in the most humid rooms.

The only negative is the price. Take a look at the price tags that are now on display in popular construction stores - and decide for yourself whether you can afford such an expensive sound insulator for the ceiling of your apartment.

Wood boards

• average cost;
• average sound insulation;
• considerable thickness;
• exemplary environmental friendliness.

It is perhaps appropriate to draw parallels with cork sheets - after all, we are dealing with such an organic material, however, in a number of characteristics, wood-based panels sold everywhere are noticeably inferior to them. The only gain in price is not commensurate with how much you lose in the most important thing - the level of sound insulation and the height of the room.

Here are the current prices for popular brands of wood boards. Study them thoroughly, but keep in mind all the disadvantages that we mentioned above.

Foam plastic

• simple installation;
• easy;
• average level of absorption of noise waves;
• flammability;
• release of harmful substances during operation.

Of all the modern materials available for soundproofing ceilings, foam is perhaps the most undesirable. And not at all because it does not cope so well with absorbing sound vibrations - it is simply not entirely safe.

During operation, under the influence of changing temperature conditions or high humidity, it can become deformed and release harmful substances into the space that a person can potentially inhale.

Moreover, he has highly flammable- which creates a permanent risk of fire in the apartment.

The only advantage of using polystyrene foam for such purposes is low price.

On average, a square meter will cost you from 100 rubles and higher. However, is it possible to allow such a situation that the bargaining chip for savings becomes your personal safety and the health of your loved ones?

Acoustic membranes

• frame installation;
• ideal noise absorption;
• impeccable performance properties;
• safety and environmental friendliness;
• heavy weight;
• high price.

This modern material is made from compounds of rubber, polymers and various minerals and gives a head start in terms of resistance to sound vibrations to everything that we listed above. If you decide to soundproof the ceiling in your apartment using acoustic membranes, then you will reliably protect yourself from extraneous sounds, and also prevent the active spread of noise coming directly from you.

There are a huge number of options on sale, each of which is perfect for solving the task. However, it’s better to take a look at the prices first - to once again figure out whether such costs fit into your budget or will you have to look towards cheaper materials for soundproofing the ceiling in an apartment?

Liquid sound insulators

• use as a layer between sheets of drywall;
• high price;
• easier installation compared to acoustic membranes;
• safety;
• reliable noise insulation properties;
• ease of use.

If you don’t want to bother with the installation of the acoustic membranes discussed above, then there is a reason to turn your attention to some liquid materials produced in the form of polyurethane foam. Especially if you plan to install a suspended ceiling made of plasterboard. It is impossible not to note the enormous ease of use - such materials are sold in the form of tubes, which, during direct installation, are sprayed between the sheets of drywall used.

Look at what liquid materials for soundproofing the ceiling in an apartment are now popular and how much this “pleasure” generally costs.

Conclusion

Of course, for those who have soundproofing the ceiling in their apartment on the agenda, finding modern materials to complete the task is not a problem - a wide range of products is far from the largest hardware store will serve as clear confirmation of this. However, really choose best option choosing a material for sound insulation from a variety of possible ones is a much more difficult task. It seems that our review of the most popular materials for soundproofing ceilings in an apartment will serve as a good navigator for you, and the prices for modern materials for soundproofing ceilings that we have given will save your time and help you more accurately adjust to the allotted space. renovation work budget.

Good sound insulation means silence and a relaxing time in the apartment. Various types of insulation aimed at reducing the noise level in the room help to achieve such conditions. To find out what materials for ceiling soundproofing are used in modern construction, let's look at the most popular ones today.

When choosing materials for sound insulation, it is necessary to take into account their effectiveness. This is due to the types of noise that will have to be absorbed. All noise that occurs is divided into two types:

• airborne noise is formed from air vibrations created by the mechanical action of some objects, for example, a closing door. They penetrate into the room through cracks and even sockets;
• shocks are formed from mechanical impacts on the ceiling. A strong stomp of feet spreads across the ceiling of the lower apartment. But with poor sound insulation, it can be heard in the apartment located on the floor above.

The maximum level of silence can be achieved by soundproofing not only the ceiling, but also the walls together with the floor.

Designs for ceiling sound insulation

To lay materials for soundproofing the ceiling, you can make additional structures:

• mount on a metal frame suspended ceiling. It is attached to the floor slabs with hangers;
• install a suspended ceiling, which is fixed with special brackets around the perimeter of the room. Modern manufacturers offer a huge selection of fabric-based or PVC stretch fabrics;
• You can make a hemming structure from any sheet material, attached to metal frame on the ceiling.

When making any of the structures, it is necessary to leave a gap between it and the floor slabs for laying soundproofing material.

Arrangement of sound insulation without making a frame

By doing the soundproofing of the ceiling in your apartment yourself, you can avoid the labor-intensive and costly process of making a frame. This method is suitable for laying sound insulation under a suspended ceiling. There are two ways to do this:

Separation of soundproofing material by type

The structure of each material has its own characteristics, which determine the percentage of noise elimination in the apartment. Properly selected material can provide 99% silence protection. To understand the structure of the entire noise protection system, you need to know that according to functionality, materials are divided into two types:

• The structure of the sound-absorbing material has a soft, porous or fibrous filler at its base. A sound wave passing through a material is first slowed down and then completely absorbed. Such materials include slabs based on felt, basalt and padding polyester, mineral wool;
• soundproof. Its functionality is exactly the opposite of the type considered. The dense and strong structure does not absorb sound, but reflects it away from itself. Such materials are concrete, brick and other analogues.

The best noise protection effect is achieved by using both types of material together. It is a kind of sandwich construction with two outer layers of sound insulation and one inner layer sound absorption.

Types of materials

Good sound insulation of an apartment, made by yourself, depends on the thickness and quality of the material used. Today, the consumer is offered a huge selection of well-known products and new products, for example, membranes, cork and others.

Basalt wool

Basalt wool has a high degree of sound absorption due to the fact that it has a special sound absorption structure that differs from basalt insulation panels. Materials with such a base include slabs different manufacturers, for example, “Shumanet BM” or “Acoustic Butts”. The slabs are resistant to fire and rot. Their disadvantage is the release of small particles and an unpleasant odor. chemical substance. But this problem is easily solved with the installation of additional sealing. Sound absorption efficiency basalt wool observed when using slabs with a thickness of 50 mm.

"Zvukanet Universal"

This type of insulation is made from fiberglass. Fourteen-millimeter filler is enclosed in containment– polypropylene membrane. Once installed, the insulation does not require sealing, which reduces the complexity of DIY work and is cost-effective.

Minvata

Probably the first and most common material can be considered mineral wool. In addition to noise absorption, it reduces heat loss, is easy to install, and has a lower cost compared to other modern insulation. Mineral wool is available to consumers in the form of a mat or roll.

To install it, you will need to construct a wooden frame on the ceiling with your own hands. Its slats should have a smaller pitch so that the cotton wool fits tightly under them. For reliability, mineral wool is nailed down with nails or plastic umbrella dowels.

The disadvantage of mineral wool is its instability to dampness. To prevent it from swelling from moisture, waterproofing is laid underneath it and covered with a vapor barrier film on top. This is especially important in apartment rooms such as the bathroom and kitchen.

Traditional polystyrene foam

A slightly outdated, but not inferior in popularity, material is polystyrene foam. It is also an excellent insulator. And although it cannot be classified as an environmentally friendly raw material, moreover, it is fire hazardous and releases toxic substances when burned, expanded polystyrene is in demand. This is due to its low vapor permeability and ease of installation with your own hands without outside help.

Its structure consists of balls increased in volume due to gas saturation, which gives them greater elasticity. The slabs are produced in thicknesses from 20 to 100 mm. Their noise absorption level is 23–25 dB.

During installation, the slabs are fixed to the ceiling polyurethane foam or liquid nails. For reliability, plastic umbrella dowels are used.

Wood based insulation

Environmentally friendly Izoplat and Izotex boards are made from wood fiber without the addition of fastening agents. adhesive compositions. Wood is used in their production coniferous species trees. The slab thickness of 125 mm reduces sound transmission by 23 dB, and the decorative surface is available in four colors. Its edges have a tongue-and-groove connection, which allows you to do it yourself seamless styling. The slabs are fixed to the ceiling with glue or nailed with staples onto a wooden frame.

What is the Isotex ceiling panel made of?

Natural cork, due to its porous structure, reduces noise penetration at low thickness. The boards are environmentally friendly and have light weight, but are highly expensive. To protect your apartment from noise penetration, cork slabs are glued to a plasterboard sheet, after which this sandwich is attached to a frame for a false ceiling with the insulation inside. If the cork is simply glued to ceiling slabs ceiling, then it will protect the apartment located on the floor above. This is the peculiarity of the cork slab.

Soft fiberboard boards, for example, “Softboard” are made from wood waste without synthetic additives. The wood is split into fibers and piled like wool. Finished slabs 8-20 mm thick are fixed to the ceiling with plastic umbrella dowels.

Ecowool is an affordable insulator. Although it is made from recycled paper, the material is resistant to rotting and damage by rodents. Ecowool is used when installing a false ceiling, simply pouring it onto plasterboard up to 70 mm thick.

Natural fiber insulation

Toward natural and environmentally friendly clean materials include slabs made from felt, coconut and flax fiber. Insulation is recommended for use in children's, medical and residential premises.

Eco-friendly insulation and insulation Coconut, fire safety class G3-G4

Membranes

Membranes have been gaining popularity recently. The small thickness of the PVC sheet of 3 mm can reduce the noise level by 26 dB. It can be used as the main insulator when installing a false ceiling or as protective layer basalt insulator. Installation is easy to do yourself. The only negative is the heavy weight, so you will need 2-3 people to work.

Ceiling soundproofing membrane

Liquid insulation

Easy-to-use liquid insulation is packaged in special containers, from which it is applied to the ceiling with a mounting gun. A good sound insulation effect is obtained by installing a two-layer false ceiling. Liquid insulation is applied between two sheets of drywall, screwing the resulting pie with self-tapping screws to the frame.

Modern environmentally friendly insulation

Finally, I would like to pay attention to two more environmentally friendly and modern materials:

Having considered many types of soundproofing materials, I would like to add that this list may be far from complete, since progress does not stand still, and new types of insulation will appear over time.

Despite the beauty and practicality of stretch ceiling covering, it cannot boast of high soundproofing characteristics. IN apartment buildings The problem of noise from neighbors is especially pressing. In this case, before installing the tension fabric, the ceiling is soundproofed. There are many materials available for sale that are suitable for these purposes. They all differ in their characteristics and installation features. We will look at the features of each sound insulator and the nuances of its installation, which will help the consumer find the answer to the question of how to soundproof a ceiling under a tension covering.

Selection of soundproofing material

Even when using acoustic tension panels, protecting an apartment from extraneous sounds will be ineffective. If such fabrics are used in conjunction with insulators made of other materials, the noise absorption of the coating will increase significantly.

Today you can find the following materials for soundproofing the ceiling on sale:

• mineral wool and products based on it;
• expanded polystyrene;
• cork slabs and rolled products;
• foam;
• Mineral-based sound insulator Texaund.

Before installing any insulator, the base surface must be prepared. In addition, it is necessary to install baguettes for the tension fabric, which will subsequently hide the sound insulator.

Preparing the ceiling and installing the supporting frame

Work to prepare the base surface depends on its condition:

1. For high-quality painted ceiling surface acoustic materials can be installed without prior preparation.
2. It is better to completely remove weak base surface coatings and finishes with defects.
3. After this, the ceiling is cleaned with a wire brush down to the floor slabs and the dust is removed.
4. The primer is applied in several layers. The primer coating is applied to the walls to a height of 15 cm. Before applying each layer of primer, the first layer must be completely dry. If mold is present, use antifungal primers.

After preparing the base, install the load-bearing moldings. To do this, the installation level of the tension covering is drawn along the perimeter of the room on the walls. For this they use laser level and painting cord. The baguettes are cut to length and self-adhesive soundproofing tape is attached to their back side. After this, the profile is applied with tape to the wall and screwed with self-tapping screws.

Then the installation locations are marked on the base. lighting fixtures. For this purpose, special platforms made of plywood or OSB are installed. The bases for the devices are mounted at the same level as the tension fabric and are mounted on perforated hangers. Power supply cables are laid to the installation sites of lighting devices.

Features of soundproofing materials and installation technology

After preparing the base surface and installing the mounting moldings, sound insulation can be installed under the suspended ceiling. Since there are many acoustic materials suitable for these purposes, we will consider their features and installation nuances in detail.

Roll sound insulation MaxForte

Recently, turnkey ceiling soundproofing is often done using a new generation of roll insulation - MaxForte from SoundPro. With a thickness of 1.2 cm, this product protects well from impact noise and airborne sounds. The noise insulator does not contain glue and can be used in frame and frameless insulation systems.

The advantages of MaxForte from the SoundPro brand include the following:

• does not emit unpleasant odors;

• resistant to rot and moisture;
• not susceptible to damage by insects and mold;
• retains original dimensions (does not shrink);
• provides maximum sound absorption.

Important! MaxForte is attached to the ceiling surface using dowel mushrooms.

Mineral wool

It is better if the soundproofing of the ceiling in an apartment under a suspended ceiling is carried out not with ordinary mineral wool, but with modified products based on it - Shumostop K2 and C2 slabs, as well as Shumanet BM.

Schumanet slabs are made from basalt fibers. On one side the product is reinforced with fiberglass. This ensures high rigidity of the material.

Technical characteristics of the sound insulator:

• dimensions – 1x0.5 m or 1x0.6 m;
• thickness – 5 cm;
• density - 45 kg per cubic meter;
• There are four slabs in the package;
• area of ​​one element – ​​2.4 m²;
• package weight – from 4.2 to 5.5 kg;
• volume – 0.12 m³;

• average sound absorption – up to 27 dB;
• when immersed in water for a day, water absorption is no more than 3%.

Shumostop slabs are produced in two varieties C2 and K2. Their characteristics are as follows:

1. Dimensions – C2 1.25x0.6 m, K2 1.2x0.3 m.
2. Thickness – both slabs are 2 cm.
3. Density – 70 kg/m³ for C2, 90-100 kg/m³ for K2.
4. There are 10 slabs sold per package.
5. Element area – 7.5 m² C2, 3.6 m² K2.
6. The weight of one plate is 11 and 8.8 kg, respectively.
7. Volume – C2 0.15 m³, K2 0.072 m³.
8. Average sound absorption is up to 27 dB for C2, up to 20 dB for K2.
9. Both materials are non-flammable.
10. Water absorption per day is 2-3%.

When using mineral wool slabs, the price of ceiling sound insulation will be the most affordable. Typically, C2 and K2 products are used simultaneously, because the fiberglass insulator absorbs noise better, and the K2 elements are not harmful to health. Therefore, C2 is attached to the ceiling first, and then K2. In this case, the sound wave damping reaches 46 decibels.

Installation features

The frame installation method involves the construction of sheathing on the ceiling surface. To do this, marking is first performed. Then the guides are attached (their pitch depends on the width of the slabs). The frame is made of metal profiles or wooden blocks.

When using steel profiles, they are additionally sound insulated. To do this, use self-adhesive tape. Depending on the thickness of the sound insulator being laid, the frame is attached directly to the ceiling or suspended from it using perforated hangers. After assembling the frame, acoustic slabs are laid. They should fit snugly against the guides and fill their entire thickness. The material is laid without gaps, without any gaps.

The frameless installation method involves gluing the slabs to the surface with gypsum or cement-based glue, as well as adhesive sprays. Choice glue mixture depends on the material of the surface to be glued. For concrete ceilings, mixtures based on gypsum and cement are suitable. Additionally, dowel-fungi are used (5-6 pieces per slab). For painted surfaces it is better to use spray adhesives (additional fixation with dowels is not required).

Important! If perforated tension fabrics are used, then to protect against mineral wool getting into the air, the insulator is covered with a vapor barrier film. To fix the film, use dowel mushrooms, double-sided tape or fastening with staples to the sheathing.

Expanded polystyrene

Soundproofing the ceiling in an apartment under a suspended ceiling is performed using regular and extruded polystyrene foam.

Characteristics for regular (extruded) polystyrene foam are given below:

1. The percentage of water absorption per month is 4 (0.4).
2. The percentage of water absorption per day is 2 (0.2).
3. Vapor permeability is absent in foam plastic (for extruded material it is 0.018).
4. Thermal conductivity – up to 0.05 (up to 0.03).
5. Sound absorption – up to 53 dB (up to 27 dB).
6. Density – up to 35 kg/m² (up to 45 kg/m²).
7. Strength – up to 0.2 MPa (up to 0.5 MPa).
8. Mechanical strength for static bending – up to 0.2 MPa (up to 1 MPa).
9. Operating temperatures – from minus 50 to plus 70 (75°C).
10. Flammability – G1-G4.

If unpressed self-extinguishing polystyrene foam is used, then it is better to choose PSB-S class 35 or 25 products. The material is attached to the surface with liquid nails, cement-based adhesives or polyurethane foam. For additional fixation, dowel-fungi are used. The same can be said about fixing extruded polystyrene foam.

The general advantages of all polystyrene foams include their low thermal conductivity, high degree of sound absorption, resistance to mold damage, and low weight. The disadvantage of the material is flammability and the release of toxic substances during a fire.

Soundproofing Texound

Texaund is characterized by high sound absorption and low thickness. This dense material absorbs and scatters sound waves well because it has a high density.

Texaund is produced in the form of rolls and plates and has the following characteristics:

• density – reaches 1900 kg/m³;
• flammability - G2;
• average sound absorption – up to 3 dB;
• elongation under tensile loads – up to 300 percent;
• composition – polyolefins, plasticizers, spunbond, aragonite.

The insulator is available in different sizes and has the following advantages:

1. Resistance to temperature changes (withstands even freezing at a temperature of -20 degrees).
2. Its elasticity is similar to rubber.
3. The surface is not susceptible to fungi.
4. High moisture resistance.
5. Unlimited service life.
6. Can be used in combination with other acoustic materials.

Important! On sale there is Texaund with a self-adhesive base, on a felt pad, with a foil layer, and a regular one.

Mounting options

There are three ways to install this sound insulator:

1. If Texaund is used as an independent sound absorber, it is glued to the ceiling surface with special glue (liquid nails or sealant). The composition is applied to the ceiling and insulator. After a quarter of an hour, the canvas is applied to the base and pressed tightly. Due to its heavy weight, Texaund is glued in separate sheets. Adjacent slabs are first laid with a slight overlap, then cut with a cutter and joined at the ends, followed by welding gas burner or a hair dryer. After this, the sheets are additionally fixed with dowel mushrooms, which are mounted in increments of 0.5 m.
2. The second method involves preliminary installation on the ceiling of mineral wool laid in the gaps of the sheathing. After this, Texaund is glued to the drywall, which is then mounted on the sheathing. The joints are glued with sealant or welded with a construction hairdryer.
3. In this option, Texound is first attached to the ceiling surface, as described in the first method. Then the frame is mounted from wooden beam or metal profile. Mineral wool is placed between the guides. The frame is hemmed with plasterboard or vapor barrier film. The tension covering is being installed.

Acoustic foam

This is the most affordable insulator, which has an impressive service life and is used both independently and in combination with other acoustic products. Because of its lightness, foam rubber is glued to the base with silicone or double-sided tape. The thickness of the foam rubber plates is 25-100 mm. The relief pattern of the surface may also differ. There are special reliefs that are designed to dampen low-frequency noise.

To prevent neighbors from above from bothering you with the details of their everyday life, it is recommended to arrange at least basic sound and noise insulation of the ceiling. And how to do this correctly for tension systems - we will tell you in today's instructions.

The “cardboard quality” of many domestic buildings has long been the talk of the town. To prevent neighbors from above from bothering you with the details of their everyday life, it is recommended to arrange at least basic sound and noise insulation of the ceiling. And how to do this correctly for tension systems - we will tell you in today's instructions.

Types of noise and methods for eliminating them

In the context of construction and renovation, noise is divided into two main categories: structural and airborne, the name corresponding to the path of its propagation. The sources of each type of noise also usually differ. Airborne - this is music, the human voice, the sounds of animals and working household appliances. Such noise is neutralized by damping air vibrations in a layer of porous, easily compressible material.

Structural noise, otherwise called impact or structural noise, occurs when there is intense impact on various parts of the building structure. Examples of such noise include chatter from washing machine, the sound of heels, although the most notorious is still the noise from an impact drill or hammer drill. The spread of noise of a structural nature is eliminated with the help of damper inserts at the junctions of one part of the structure with another, for example, between the ceiling and the reinforced belt of the wall.

In addition, in fact, even structural noise is perceived by humans as airborne, that is, at some point the building transmits vibrations to the air. A secondary way of sound insulation can be to dampen this vibration over the entire area of ​​communication between the walls and ceilings and the space inside the apartment, however, this method is considered more expensive in terms of material consumption.

One must come to terms with the fact that it will not be possible to completely eliminate the penetration of noise into the apartment from the outside, just as it will not be possible to achieve complete absorption of sounds arising inside the room. However, it is quite possible to bring the noise absorption of walls to the standards specified in SP 51.13330.2011. Thus, the optimal degree of sound insulation of walls is about 80–90 dBA for low-frequency noise (walking, impacts) and half as much for high-frequency noise (music, voice).

Does a suspended ceiling provide any advantages?

When working with a stretch ceiling, we are faced with a flat canvas enclosed in a frame of a baguette profile. Unlike suspended ceiling structures, the only way to transmit structural vibration is through the connection of the fastening profile to the walls.

The propagation of low-frequency structural noise through the ceiling is prevented by gluing damper tape under the mounting profile. If this is not done, you can end up with some kind of speaker the size of the entire room. Note that not all frequency ranges will be amplified through the ceiling; for example, high-frequency noise is damped due to the elasticity of the film.

With air noise and structural vibration of the ceiling, the situation is somewhat worse: the tension canvas practically does not prevent their spread and even enhances it. At the same time, the plane of the rough ceiling remains completely free for installing any kind of sound insulation of any thickness.

Dependence on the type of building

Work to eliminate construction noise must be planned in accordance with the structure of the building. In frequent cases, the most attention is required to the junctions between walls and floors and the peculiarities of sealing joints and technological cavities. In some cases, you can even come to the conclusion that surface installation of sound insulation will not give the desired effect.

A classic example of this is panel house with single-layer flooring with hollow slabs. In such buildings, acoustic resonance often occurs due to the rigid connection of the slabs to the wall panels. The optimal solution is not soundproofing the ceiling, but cooperation with neighbors above to install their floor using floating technology.

Frame floors without filler can be modified by adding polystyrene chips or sawdust, which will have a good effect on their sound absorption. In some cases, it is useful to re-seal the load-bearing beams in the walls or technological seams. For example, you can install damper pads and inserts made of porous incompressible material.

Selection of sound-absorbing material

In ordinary cases, installing slab or roll materials, dissipating air vibrations to produce white noise with acceptable intensity. In this case, both special composite materials and conventional insulation materials such as mineral wool are used.

Soundproofing the ceiling with mineral wool

The advantages of special materials include their high efficiency, while the disadvantages include their equally high cost. The best damping of air vibrations occurs at the boundary of two dissimilar media, for example, cardboard and mineral wool. A secondary role is played by the shape and size of the cells, the density of the materials and the order in which the layers are applied.

All these principles can be used when self-production soundproofing cake. However, you should avoid the advice of amateurs and understand that materials such as polyurethane foam, EPS, egg trays, cork and other “innovative” noise absorbers do not have any positive effect, and in some cases even worsen the situation.

The most suitable are felt, mineral wool with a density of 40–60 kg/m3, acoustic mineral wool, wool and coconut fiber. From specialized materials You can cite Tecsound rolls and AcousticWool mats as the most effective for soundproofing ceilings.

Features of installation of sound insulation

Performing soundproofing of the ceiling when finishing it tension fabric, you avoid the need to install a frame suspension system that prevents the spread of structural noise. All that is necessary is to attach one or more layers of sound-absorbing material to the rough surface.

The separation of air media should first be ensured, since the direct transmission of airborne noise occurs most intensively. In general, covering the ceiling with cellophane helps, but such actions require caution so as not to disturb the climate in the room. If the ventilation and insulation system requires free gas exchange through the interfloor ceiling, it is necessary to use vapor-permeable membranes.

In general, sound insulation is attached to the ceiling using disc dowels used in a wet façade system. Their length and installation pitch depend on the thickness of the material, its density and ability to retain its shape. It is most difficult to install multilayer insulation, where temporary fixation of the applied layers is required. For these purposes, you can use point gluing or a structure that supports the cake until it is finally fixed.

In one of the most effective noise absorption pie concrete ceiling pasted over with two layers of corrugated cardboard on silicate glue, then a temporary support system is assembled from the ceiling profile for gypsum boards. Acoustic wool is laid in rows on the slats in mats of 60–70 mm each, and a felt carpet about 10 mm thick is placed under it. Denser material in the bottom layer allows for better noise absorption and the use of fewer fasteners.

Pairing with soundproofing walls

When installing ceiling sound insulation, it is important not only to tightly join the elements of the insulator itself, but also to achieve minimal interaction with the sound insulation of the walls. A suspended ceiling allows you to build false wall cladding not right up to the ceiling, and you need to take advantage of this advantage.

To be sure that at the corner junction of the wall and the ceiling there will be no space left for the free propagation of airborne noise, the edges of the ceiling sound insulation must be wrapped and brought into a hidden plane just below the level of the tension covering.

If there is a filler behind the false wall that helps absorb sound, you should make sure that its upper open edge is smooth and the ceiling insulator will fit snugly against the wall insulation. No special fastening is required in this place, you just need to achieve a tight laying without air gaps and make sure that the rigid surface of the sheathing is at some distance from the horizontally located insulation layer, that is, does not rest against it. published
