Soundproofing the ceiling under a suspended ceiling by hand. Sound insulation for suspended ceilings: types and installation methods. Installation of thin composite sound insulation with glue

Stretch ceiling is a finishing that allows you to obtain a perfectly even surface without laborious puttying work. Communications are hidden under the canvas or PVC film. The design can be multi-tiered and supplemented with lamps. The benefits are obvious. There is only one drawback - such canvases are not soundproof, so soundproofing the ceiling becomes a problem that must be solved before installing the finishing. Let's consider materials suitable for use, their features and installation techniques.

Types of materials for soundproofing suspended ceilings

There are several types of insulating materials suitable for installation under stretch fabrics:

boards of ordinary or extruded polystyrene foam;
heat insulators based on mineral wool, its modifications;
cork sheets and slabs;
foam mats;
modern mineral-based sound insulators such as Texound.

On a note! There are acoustic stretch ceilings on sale that have noise-proofing properties. The structure of the fabric with fine perforations dampens minor waves. To achieve 100% results, it is recommended to do additional insulation.

Characteristics of materials for ceiling insulation and installation technology

Before soundproofing the ceiling, the user should study the main indicators of materials, choose best option for use in an apartment.

Mineral wool

Conventional mineral wool insulation is used to insulate walls and ceilings. Today, manufacturers offer improved materials that are more practical.

Schumanet BM

The material is made on the basis of basalt fiber, with a reinforced side and a porous membrane filling. The reinforcement is made of fiberglass, so the slabs are protected from deformation and maintain shape stability throughout their entire service life.

Main characteristics:

size (cm) 100x50 or 100x60;
thickness 5 cm;
area of slabs (4 pcs.) per package 2.4 m2;
sound absorption coefficient up to 27 dB.

The material belongs to the category of non-flammable, according to its characteristics it complies with SNiP.

Noise stop

The slab product is available in two types and is marked C2, K2 - the letters matter when choosing the material.

Main characteristics:

Options	C2	K2
Material of manufacture	Hydrophobic staple glass fiber	Basalt fiber
Application	Insulation insulation of floors	Insulation, insulation of ceilings
Size(cm)	125x60	120x30
Thickness(cm)	2	-
Density (kg/m3)	70	90–100
Total area of slabs in packaging (m2)	7,5	3,6
Sound absorption coefficient (dB)	27	20

The materials belong to the group of non-combustible materials and are most often used in combination. C2 has a high noise insulation threshold, K2 is safe for health. First, fiberglass slabs are laid, then basalt - this design absorbs sound waves up to 46 dB.

Rules for laying out mineral wool slabs

Soundproofing of the ceiling in the apartment under suspended ceiling in the following way:

The base surface is equipped with lathing. The cells are formed in increments of 55 cm. The frame can be wooden or metal. The width of the guides is less than the distance from the base ceiling to the tension fabric.

Important! The metal profile for the frame is covered with a special tape to improve the quality of sound insulation.

Laying out slabs of acoustic material. Place tightly to the base surface. When laid out on a frameless surface, the slabs are glued end-to-end. Laying in the frame is carried out with a tight connection between the sheathing parts - by surprise.
The adhesive composition is selected according to the type of ceiling. For concrete - cement, on a painted surface - spray. After fixing the slabs, additionally secure the insulation with dowels - 5 fasteners per sheet.
Place a membrane on top of the slabs to reduce the risk of fibers falling onto the tension fabric. The membrane is fixed to the sheathing using staplers or double-sided tape.

After the glue has dried, the trim is stretched.

MaxForte

Moisture resistance, resistance to mold and mildew. The product is not food for rodents.
Unlimited service life.
Compatibility with any other insulating materials.

The product is produced in different sizes, supplemented with a self-adhesive, foil or felt layer.

Laying Texound

The type of installation depends on the basis on which the soundproofing of the ceiling in an apartment under a suspended ceiling is made.

There are three installation methods:

Laying on a flat surface is carried out using glue. First, the composition is applied to the plane, left for up to 15 minutes, then sheets of insulating material are applied. Installation is overlapped, with overlapping edges up to 5 cm. After this, make an incision along the alignment zone, join the edges of the elements and weld them gas burner or a hair dryer. It is permissible not to cook, but to glue the joints with liquid nails. After fixing with glue, the canvases are secured with dowels in increments of up to 50 cm.

On a note! Sheets with an adhesive base are easier to install - remove the protective paper, lay the material on the ceiling, and press it.

The sheathing is formed, mineral wool insulation is placed in the cells, and Texaund is placed on top. Seal the seams between the sheets with sealant, then line the ceiling with gypsum plasterboard sheets and install the tension fabric.
The entire ceiling is covered with Texaund sheets, taking into account the welding of the seams. A sheathing or frame is installed on the surface for laying out mineral wool insulation. Then the surface is hemmed with gypsum board sheets, after which it is finished with tension fabric.

On a note! To ensure strong fixation, Texound is always recommended to be secured not only with glue, but also with dowels. Homakoll adhesive is sold in 8 liter canisters.

Expanded polystyrene panels

Modified foam boards are up to 10 cm thick and are made from unpressed or extruded polystyrene foam.

Characteristics:

Unpressed foam plastic is designated PSB-S and is produced from granules of different sizes, which determine the density, strength and sound insulation performance. For finishing ceilings, it is recommended to use materials with medium and low density, light weight, for example, PSB-S 25/35. Fixation with glue without aggressive solvents, so as not to deform the materials. Laying end-to-end, seal the seams with tape, additionally secure with dowels.

Extruded polystyrene foam has a high density and is produced by extrusion - pressing raw materials through special molding nozzles. The plates are equipped lock connection tongue and groove, which makes installation easier. They are also produced in the format of small lamellas; after laying out, a smooth monolithic surface is obtained.

Important! With a thickness of 2 cm, extruded polystyrene foam dampens and disperses shock and sound noise up to 27 dB. The indicator increases with increasing thickness.

The same materials are used for laying out the sheets as for standard polystyrene foam.

Advantages of both types of expanded polystyrene:

light weight;
resistance to mold, mildew;
reduced coefficient of thermal conductivity, increased coefficient of sound absorption.

Flaws:

The materials belong to the flammable class. When heated, substances harmful to the body are released.
Does not tolerate UV rays.
During its service life it will self-decompose, crumble and require replacement.

Installation is simple, the slabs are glued to the ceiling, then fixed with dowels. For hardware, holes are pre-drilled in the elements. Drill with a drill, being careful not to crumble the foam.

Acoustic foam

The porous structure of foam rubber provides high-quality absorption of impact noise and sound waves of significant strength. Materials are used as a main or additional layer; it is permissible to veneer any surface, including walls and floors. Fixation with double-sided tape or glue. This is the most affordable ceiling sound insulation, the price of which does not exceed $10 (650 rubles) per 1 m2.

Long service life, light weight and a variety of color and texture solutions allow the use of foam mats for surface finishing as a finishing coating. Relief products have a cone height of up to 10 cm.

On a note! The mats are available in different texture solutions: Wave, Cells, Pyramid. Sheets are also produced to insulate low frequency waves.

The installation rules are simple:

For fixation, heated silicone, spray glue, liquid nails or double-sided mounting tape are used.
For suspended or suspended ceilings, a lath is formed or a frameless installation option is used.
The foam rubber is laid out on a clean, dry surface. It is important to ensure that the sheets adhere tightly to the base.
Laying elements end-to-end, filling the entire surface of the ceiling plane. The lathing is installed on top of the material in increments of 60 cm - it all depends on the relief of the sheets.
Lamps are installed on top of the sheathing, and the plane is hemmed with plasterboard sheets in case suspended ceiling or sheets of drywall will serve as an additional insulating layer.

Advice! Foam rubber sound insulation under a suspended ceiling is glued to the base base. The basic rule is to lay it tightly to the surface without gaps or gaps, so it is better to coat the sheets entirely or use the composition in the form of a spray.

Preparatory work on the ceiling and rules for installing the frame

Lathing is required for bases with uneven surfaces and protrusions. Forming a frame reduces the risk of a loose fit of materials for soundproofing the ceiling and increases the quality indicator.

Preparatory work is carried out as follows:

Assess base surface coverage. Smooth ceilings do not require preparation; the insulation is fixed on them immediately.
If there are areas of peeling paint or plaster, clean the areas and remove dust. Prime the surface with a deep penetration primer containing antiseptics. Apply 2 coats of primer, allowing the first to dry before applying the second.
After drying the ceiling, find the lowest corner in the room, mark the height of the frame formation along the wall, and transfer the marks to all corners. Connect the points with a horizontal line - this is the border of the frame guide rails.
Cut profiles the right size. Cover metal elements with soundproofing tape on the side adjacent to the wall. Press the profile with the tape to the wall, screw it with self-tapping screws or dowels in increments of up to 15 cm.
Mark the mounting points for the lamps. Install special bases made of plywood or timber under the devices; the thickness of the base depends on the weight of the lamp.

Important! The base plane is located at the same level as the tension fabric. The platform should not protrude under the finishing.

Connect the cable to the lamps. Install the necessary equipment, pull the cable tightly to the ceiling, secure with clamps. It is more convenient to lay the wires in a special protective corrugation - this will reduce the risk of fire in the event of a short circuit.

Now, fasteners are installed in the area where the lamps are installed, so that after the fabric is stretched, the auxiliary elements of the devices are under the finish.

If it is impossible to carry out the work with your own hands, the owner has access to a service from the craftsmen. How much will turnkey ceiling soundproofing cost depends on the coverage area, volume preparatory work, layout techniques and materials.

To achieve high-quality sound insulation, it is recommended to decorate all planes of the room with materials, since reinforcing belt is a good conductor of sounds. In this case, finishing the ceiling solves the problem by only 30%.

Soundproofing the ceiling in an apartment under a suspended ceiling hides defects in the ceiling, communications (electrical wiring, ventilation ducts) and soundproofing materials. Tensioners and suspension systems– this is a kind of decoration hiding mounting elements.

Advantages of this method:

The speed of preparing the ceiling for frameless installation soundproofing panels;
Possibility of replacing old wiring without making grooves;
Wide selection of suspended ceilings with sound insulation (additional sound insulation).

It should be said right away that soundproofing stretch ceilings or, as they are also called, acoustic - do not guarantee 100% sound insulation, but in combination with other soundproofing materials installed between ceiling space, give positive effect.

The soundproofing effect of soundproofing stretch ceilings is achieved by the special properties of the fabric. The French company Barrisol produces microperforated fabrics noise absorbers, improving acoustics in the house. There are suspended ceilings soundproofing impact noise: clatter of steps, work household appliances, creating vibration waves.

The essence of such a system is isolate transmission sound vibrations from the main ceiling to the suspended ceiling and the walls of the room. This task is performed by damper pads installed under the tension profile. Sound waves, when passing from one medium to another, are reflected, refracted, absorbed, and bend around obstacles. The energy of the sound wave is damped by the micropores of the fabric, where it turns into heat.

Sound waves are partially reflected from the canvas (2), but most are absorbed by micropores (3), which are applied in an amount of 250,000-300,000 per 1 m2. The diameter of the holes is 0.1 mm, the distance between them is 2 mm.

Part of the sound waves penetrates the canvas, where, upon transition to air environment they are refracted, partially extinguished, reflected from the main ceiling and finally extinguished by tension fabric. The hanging profile (1) is attached to the wall using sealing soundproofing adhesive and screwed with screws for strength. This soundproofing of a stretch ceiling effectively prevents the spread and absorption of noise, improving the acoustics in the room.

Damper suspension (1) only partially prevents the propagation of impact noise, which have a different nature of distribution: vibration from steps, the operation of household appliances is transmitted to the ceiling support (wall) and penetrates the room along the wall. This type of sound transmission is called structural.

Advice. To reduce these vibrations, the soundproofing of the ceiling in an apartment under a tension system is carried out by installing noise insulating materials that are attached to a special frame, or directly to the ceiling.

Soundproofing the ceiling under a suspended ceiling

The problem of noisy neighbors cannot always be solved with acoustic tension systems. The best decision – soundproofing the ceiling under a suspended ceiling. This will provide protection from impact noise. Additional sound insulation of a stretch ceiling in the apartment is carried out by installing soundproofing mats mounted directly to the base of the floor. The picture shows the soundproofing of a suspended ceiling in an apartment. Selected acoustic system CLIPSO ACOUSTIC.

The kit includes: (1) – acoustic canvas, (2) acoustic mats, covered vapor barrier film, (4) – fastening plastic dowel umbrellas, (3) – wall profile.

Installation instructions for ceiling sound insulation under a suspended ceiling

Before attaching the soundproofing mats to the concrete slab, work is carried out to clean the old cladding and lay out communications (electrical, ventilation ducts).

Before installing wall profiles, mark the locations of the grooves (1) so as not to damage the wiring. Seal the gaps between the ceiling and wall polyurethane foam, this will create a damping soundproofing layer.

Installation of profiles is carried out by applying glue to the side adjacent to the wall.

After installing the profiles around the perimeter of the room, they begin installing sound insulation of the stretch ceiling using acoustic mats with a vapor barrier. In addition to vapor barrier functions, the film protects the ingress of small particles onto the canvas.

The acoustic panel is secured with 4-5 plastic dowels with wide heads. This is what the room looks like after installing soundproofing of the ceiling in an apartment under a suspended ceiling with soundproofing panels.

All that remains is to stretch the acoustic sheet. This is what the ceiling looks like after installing sound insulation under a suspended ceiling in an apartment.

This method of sound insulation is called frameless. Let's consider another method that is suitable for both soundproofing suspended ceilings and soundproofing suspended ceilings - this is frame method. This method performs sound insulation and thermal insulation at the same time.

Soundproofing the ceiling under a suspended ceiling with frame manufacturing

The method is based on installing a frame, inside of which a sound is placed insulating material. Before installing the frame, the floor is prepared: the old finish is cleaned, uneven areas and cracks are puttied. Then a damping soundproofing tape is glued along the perimeter of the wall.

Vibrosil glue, onto which the soundproofing tape is glued, together form a damping layer separating the ceiling panels and the wall. The damper (anti-vibration) suspension shown in the picture dampens floor vibrations. The hangers are attached to the concrete slab to the width of the soundproofing panels.

After installing the damper suspensions (1), profiles are screwed to them, between which noise insulating materials are placed.

Here (1) is an anti-vibration suspension. (2) – ceiling metal profile. (3) – damper tape. After installing the profiles, soundproofing sheets “SCHUMANET” are laid between them. GKL is attached to the profiles with self-tapping screws.

GKL - (1), sound insulation - (2), trimming the visible part of the soundproofing tape - (3). The installation height of the profiles is adjustable horizontally. With this installation, the ceiling height will be shortened by 8-15 mm. Next comes Finishing work, primer, smoothing seams, putty, painting or wallpapering. If the height allows, then finishing is not performed. GKL is decorated with a stretch ceiling.

In a private house Soundproofing the ceiling in an apartment under a suspended ceiling is carried out by installing a frame of 50x50 mm bars between the floor beams or directly on old ceiling. For better insulation sleeping area performs a single wooden frame as shown in the picture.

Vertical wooden racks(1) – board 50 x 100 mm, (2) – horizontal beam, (3) – ceiling lathing. The wooden fiber structure of the timber dampens impact noise. Then there are several soundproofing options:

Laying sound insulation into the sheathing and then covering the frame with gypsum board sheets;
Covering only the walls with gypsum fiber board sheets, followed by installation of a stretch ceiling;
Covering the frame only with gypsum board sheets, without installation soundproofing materials, since sheets of plasterboard with a fibrous structure are themselves excellent soundproofing materials.

Instead of traditional gypsum fiber board, the sound insulation sheathing under the suspended ceiling is made with fiberboard sheets, PVC panels, wood siding, eurolining...

Advice. Do not forget that sound insulation, like thermal insulation, loses its specifications if the material gets wet. Performing soundproofing of a stretch ceiling in an apartment with high humidity, take care of vapor barrier.

Useful video

In the video, let's look at expert advice on what you can do to protect yourself from noise from above:

A soundproof stretch ceiling is only part of the solution to the problem of noisy neighbors. It is much easier to negotiate with neighbors about soundproofing the floor, especially when they are doing renovations. Arrange for a soundproofing underlay to be placed under the finished floor. If neighbors live under your apartment, then you must soundproof your floor yourself: lay a carpet, place shock-absorbing mats under household appliances.

IN It is difficult to achieve high-quality sound insulation in city houses. Extraneous sounds especially bother residents of panel houses, where sound insulation requirements are, by definition, lower. In order to make their apartment comfortable and ensure silence, the owners have to take care of the soundproofing themselves. Soundproofing the ceiling in an apartment under a suspended ceiling is the easiest to install, since there are no additional strength requirements for the insulating layer.

Room with suspended ceilings

Types of sound insulation for suspended ceilings

Modern construction technology involves the use of metal-reinforced structures. Steel perfectly conducts any sounds, and vibration is transmitted to the entire structure. IN apartment buildings The main conductors of noise are floor panels. Stretch ceilings are a design that involves placing the canvas at a certain distance from the floor slab, thereby creating a gap of sufficient width for high-quality sound insulation.

Soundproofing the ceiling in an apartment under a suspended ceiling is the easiest thing to do, since no other type of ceiling allows such freedom in choosing insulating materials.

Mats of their mineral materials

For insulation works Porous materials are suitable, which are also excellent insulators. Slab insulation materials, which are widely used in construction work, can serve as excellent sound insulators, since their fibers absorb sound waves. Soundproofing the ceiling in an apartment under a suspended ceiling is most often performed using this type of material.

Mineral materials based on fiberglass or basalt have a number of positive qualities:

resistant to combustion, does not melt, does not emit dangerous gases;
has a high absorption coefficient of sound waves;
repels insects, fungi and mold do not develop on it even if it gets wet.

Styrofoam

Polystyrene foam is a lightweight and easy-to-use porous material that can be used to relieve residents of extraneous sounds and significantly insulate a room. Polystyrene foam is easy to use, it is light in weight, and is easily and quickly attached to the surface.

Since foam plastic boards have a rigid shape, fastening can be carried out without the help of glue, only with the help of dowels. Due to its rigidity, the surface of the foam can be plastered or covered with additional layers of materials, which improves the quality of sound insulation. Despite all the advantages, noise insulation of the ceiling in apartments under a stretch ceiling made of foam plastic is rarely done, since it has a significant drawback - flammability. When exposed to fire, it instantly ignites and burns, releasing huge amounts of heat and toxic gases.

Attaching foam to the ceiling with glue

Acoustic foam rubber is a mat with a special surface shape. Cone-shaped protrusions and recesses themselves serve as effective sound absorbers, and in combination with a porous material, such as foam rubber, the effect of such mats becomes very noticeable. The profile height ranges from 2.5 to 10 centimeters, the pattern resembles an egg cassette.

Installation is carried out using a special adhesive composition, and the work does not require special training or physical strength. The only drawback of the material is flammability; foam rubber flares up instantly and when burned it melts and drops hot drops of polymer, which is why the use of foam rubber as an insulator is limited.

Roll sound insulation

A thin, durable and elastic polymer, which often already has a factory-applied adhesive layer. Installation of such soundproofing occurs quickly; additional fastening with dowels is carried out in large increments, which speeds up the process. The thickness of the rolled material is not large, so sound insulation can be done even in a limited space. The sound insulation of the ceiling from rolled materials in an apartment under a suspended ceiling is made on a mineral basis, and a polymer is used as a binder, so the insulator does not ignite immediately, burns very slowly, does not form droplets or acrid smoke, which makes it ideal from the point of view of fire safety.

Stages of installation of sound insulation

Depending on the type of soundproofing material, the installation method is selected. Rigid panels, such as polystyrene foam, are attached using special dowels, soft mats - basalt slabs - are mounted using wooden guides, and glue is most often used to attach roll insulators. Despite general recommendations in each specific case it is necessary to develop an individual method of work.

Fastening with polymer adhesives

For each type of material, special adhesive compositions, which provide high-quality grip, but do not destroy the sound insulation itself. Mineral slabs and glass wool are amorphous materials, the only ones that do not collapse under the influence of aggressive chemical compounds, so the composition of the glue is not particularly important for them. Polystyrene foam and foam rubber are corroded by acid, which may be contained in some compounds. Roll materials They are also planted only on glue recommended by the manufacturers.

Fastening with dowels

For sound insulation and insulation, a special fastening method is used - using mushroom dowels.

With this fastening method, the main thing is to correctly calculate the pitch. If the insulating material is light in weight and has a rigid shape, then dowels can be placed no more often than every 60 cm. It is better to fasten soft mineral boards more securely, reducing the step to 30 - 40 cm. Typically, such dowels are used in conjunction with glue, such fastening will be especially reliable.

Modern Construction Materials And great amount information on this topic allows you to solve the issue of sound insulation on your own, without the help of professionals.

This article will help you protect your apartment from extraneous noise with minimal effort and financial resources.

What materials are used for sound insulation

If you decide to protect your home from the penetration of extraneous sounds, first of all, you need to select materials to perform this work.

First of all, you need to determine the nature of the extraneous noise. The sounds that penetrate the apartment can be divided into two conditional categories:

1. Shocks - occur during the operation of vibrating household appliances, when walking or falling objects on the floor. These sounds travel through solid materials.
2. Air. These include: noise from musical instruments, TV, audio equipment, as well as loud conversations. These sounds are transmitted through the air and are clearly audible in Soviet panel houses.

Sometimes, it is quite enough to purchase suspended ceilings with sound insulation, which “stop” both airborne and impact sounds.

This is achieved through air gap between the main and suspended ceilings, the absence of a metal frame and the use of soft fabric that absorbs any noise. The main disadvantage of soundproofed ceilings is their high price. However, there are no guarantees that the installation of these structures will provide complete protection from extraneous noise.

When choosing a material for sound insulation, it is necessary to take into account not only the above criterion, but also the following factors:

thickness of the material (no more than the space between the main and suspended ceilings);
availability of documents confirming their quality and safety for health;
sound absorption coefficient;
flammability level;
warranty period;
complexity of installation.

All currently existing ceiling soundproofing materials can be divided into three groups:

1. Soft (fiberglass, different kinds cotton wool).
2. Semi-rigid (slabs based on mineral wool).
3. Solid (compressed mineral and natural materials).

Sound absorption coefficient inversely proportional to the density of materials. For example, soft sound insulators with a minimum density of 10 kg/m3 have a coefficient of 0.95, and hard ones, with a density of up to 400 kg/m3, have a coefficient of 0.4.

Important point! Remember that high-density sound insulators absorb low-frequency sounds best, while soft materials absorb mid- and high-frequency sounds.

Taking into account all the information presented, we can conclude that to select materials it is necessary to determine the nature of extraneous noise, and then use an insulator, based on its density and sound absorption coefficient.

If the sound insulation of a suspended ceiling in an apartment does not suit you, correct the situation using one of the following materials:

mineral wool;
expanded polystyrene;
basalt fiber;
acoustic membranes;
slabs based on basalt fiber;
natural materials.

In specialized retail outlets you will be offered not only the listed soundproofing options, but also other materials, each of which has its own disadvantages and advantages.

Preparatory work

If you have decided on the choice of insulator, then you can begin preparatory work.

The main goal of these actions is to ensure reliable fixation of the material, as well as to prevent the occurrence of mold, fungi, etc.

A high-quality painted ceiling, without damage or cracks, does not require any preparatory work, you can safely install the sound insulator.

The damaged surface must be carefully treated, adhering to the following recommendations:

1. Areas with obvious defects are removed.
2. Using a stiff brush, remove dirt, dust, small bumps, etc. (the entire ceiling area is processed).
3. The ceiling and walls are primed (about 10 cm from the corner, along the entire perimeter of the room). This needs to be done 2-3 times, but each subsequent stage of work is performed only after the previous layer of primer has dried.
4. After preparing the ceiling, you can proceed to the installation of guide profiles.
5. Using a construction cord and a level, the places where the fixing elements of the stretch ceiling will be strengthened are determined.
6. Next, you need to cut the profile and glue soundproofing tape in those places where it will be adjacent to the wall. This is necessary so that extraneous noise does not spread throughout the room through metal structures.
7. The next stage is installation of the profile using dowels.
8. Be sure to mark the places where lighting fixtures will be installed. They are being treated electrical cable and the full range of work on installing lamps is carried out. At this stage you need to pay attention Special attention the electrical cable so that it does not sag, there is no damage to the insulation or potential short circuits.

If you look at it, you don’t need any special knowledge or experience to carry out the preparatory work.

A grown man who knows how to use a level and can drill holes in walls should be able to complete this task.

Mineral wool as a sound insulation material

If you have already wondered what soundproofing a suspended ceiling is, then you should know about the use of mineral wool as a soundproofing material.

This is a high quality sound insulator with excellent performance characteristics, which is sold in construction stores in rolls or slabs.

The main advantages of the presented material are:

relatively low cost;
cotton wool does not burn;
there are no difficulties during the installation process;
additionally acts as insulation.

But there are also certain disadvantages: Using cotton wool as an insulator, you will not be able to install built-in lamps, in addition, this material is very afraid of water.

Installation of wool using the frame method begins with marking the ceiling for subsequent fixation metal profile or wooden blocks. Don't forget to add soundproofing tape. This is necessary to prevent sound transmission through solid materials.

Between the frame elements, mineral wool is placed tightly and a vapor barrier film is attached. It will not only protect the cotton wool from moisture, but will also prevent debris from damaging the ceiling canvas.

Alternative option fixation of the presented material - adhesive method. It involves the use of mineral wool slabs, onto which special glue is applied. Additional fastening elements in this case are plastic dowels.

Among the specialists in this field of activity, there are those who use only the frame method, while other craftsmen prefer to glue slabs. In this case, subjective factors play a decisive role.

The use of polystyrene foam to protect the apartment from extraneous noise

Unlike the previous material, Expanded polystyrene has high moisture resistance, while it has excellent elasticity, reasonable cost and a long service life.

Installation of polystyrene foam is within the capabilities of anyone who knows how to work with their hands.

In order to strengthen presented material, there is no need to make a frame (another positive point), it is enough to use glue, dowels or liquid nails.

This insulator is designed to absorb impact sounds; it copes with other types of noise much worse than mineral wool.

Acoustic membranes and other modern soundproofing materials

Recently, sound insulation of stretch ceilings using acoustic membranes.

The presented material is produced on the basis natural ingredients (natural material– aragonite).

Unlike expanded polystyrene and mineral wool, the thickness of which can reach 10 cm, this material is very thin - up to 4 mm.

Main advantages acoustic membranes are:

High elasticity.
Ability to absorb sounds over a wide range of frequencies.
Ability to dampen impact noise.
Environmental Safety.
Doesn't lose his functionality in case of sudden changes in ambient temperature.

Main disadvantage This soundproofing material is due to its heavy weight.

In order to reliably strengthen the acoustic membranes, it is necessary to first make metal carcass or a structure made of wooden blocks.

Important point! This soundproofer cannot be installed alone; due to its heavy weight, you will need at least one assistant.

The desire to use materials of natural origin in almost all spheres of human activity has become the reason for the expression of interest to cork insulators.

This is a very light, environmentally friendly material that perfectly performs its main functions - protecting the apartment from extraneous noise.

Installation of cork slabs carried out using glue (low weight allows you to do this quickly and reliably). The main disadvantage of this material is its high cost, which is an order of magnitude higher than the price of other sound insulators.

Another type of ecological safe materials, which you can purchase if a suspended ceiling with sound insulation does not protect well from noise, this wood fiber boards. They are produced from waste from wood processing enterprises, furniture factories etc., without the use of synthetic ingredients.

The thickness of the slabs rarely exceeds 2 cm, which makes it possible to lay them in two or three layers, overlapping the joints. Wooden sound insulators are not deformable and “are not afraid” of exposure to adverse external factors.

To install wooden slabs, you can use ordinary plastic dowels. The joints between them must be treated with sealants or liquid nails.

In addition to the listed options to protect your apartment from noisy neighbors, soundproofing materials have recently been increasingly used on a fabric basis. They are made from polyester, treated with substances that form a thin film.

Their installation is carried out without any particular difficulties, and the manufacturers of these products claim that the functionality of the material is maintained throughout its entire service life, even if you very rarely use it. major renovation in room.

Another positive point The use of fabric-based sound insulators is their ability to absorb noise, both outside and inside the room. If you relax with friends or listen to loud music, your neighbors will not come running to you asking you to be quieter.

A detailed analysis of the presented topic proves that soundproofing the ceiling in an apartment under a suspended ceiling will help you always feel comfortable in your home, without fear of unexpected “concerts” in neighboring apartments.

At the same time, in order to make high-quality sound insulation, you do not need to spend a lot of money or look for experienced specialists; you can complete this task yourself.

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.

You can find it on sale today following materials for soundproofing the ceiling:

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:

For high-quality painted ceiling surface acoustic materials can be installed without prior preparation.
It is better to completely remove weak base surface coatings and finishes with defects.
After this, the ceiling is cleaned with a wire brush down to the floor slabs and the dust is removed.
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:

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;
flammability class - NG (does not burn);
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:

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

Using steel profiles They are additionally soundproofed. 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. The choice of adhesive mixture depends on the material of the surface to be glued. For concrete ceiling 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:

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

TO common benefits All polystyrene foams are considered to have low thermal conductivity, high degree sound absorption, resistance to mold damage, light 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:

Resistance to temperature changes (withstands even freezing at a temperature of -20 degrees).
Its elasticity is similar to rubber.
The surface is not susceptible to fungi.
High moisture resistance.
Unlimited service life.
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:

If Texaund is used as an independent sound absorber, it is glued to the ceiling surface 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 with a gas torch or a hair dryer. After this, the sheets are additionally fixed with dowel mushrooms, which are mounted in increments of 0.5 m.
The second method involves preliminary installation of mineral wool on the ceiling, 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.
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.
