Sound insulation under suspended ceiling. Stretch ceilings Apartments with finished soundproofing of the ceiling

If extraneous sounds penetrate into the apartment through the floor and walls by air, then the ceiling transmits mainly impact noise - stomping, falling things, rearranging furniture. Moreover, for sure, the “authors” of these sounds do not even suspect how loud they are heard in the neighboring apartment. Soundproofing a suspended ceiling in an apartment will help solve this problem.

Soundproofing under a suspended ceiling – enhancing the effect!

It is worth noting that in itself suspended ceiling is a good soundproofing membrane - sound waves are reflected from its soft, springy surface. It has long been known that solid, rigid bodies transmit sound waves much better than soft or inhomogeneous ones. The taming of sound waves also helps air gap, formed between the main and suspended ceilings - when getting from one environment to another, the sound loses its strength. However, the mere fact of having a stretch ceiling is not enough to completely drown out the sounds from above.

We also note that soundproofing the ceiling alone, even if done according to all the rules of acoustics, will not prevent extraneous sounds from penetrating through the floor and walls. Having set the goal of making your life quiet or, on the contrary, loud (but so that the neighbors do not hear it), you need to approach the issue comprehensively and carry out soundproofing work throughout the apartment.

However, soundproofing the ceiling is a priority task even in the complex of such work. Firstly, it’s just convenient to start with a more complex process without the fear of dropping the tool on the subfloor. Secondly, soundproofing the ceiling will allow you to evaluate the volume of the neighbors below and on the sides from a different point of view - perhaps you need to spend more on insulating the walls and floor more money than you thought before.

It is important to understand that specialists who know how to install do not always know how to make sound insulation efficiently. This is not their fault - the tasks are completely different, and this should be done different people. In this case, it is quite reasonable to use someone else’s ceiling installation services - you will save money on equipment, tools and time. But nothing prevents you from learning how high-quality sound insulation is made, express your recommendations to the master, pay him extra for his auxiliary role in the process of equipping the soundproofing layer and do it yourself necessary work, or manage the process.

Vulnerable frame - pay attention to the little things!

One of common mistakes craftsmen who install suspended ceilings - attaching special profiles directly to the walls. This does no harm to the ceiling, only benefit, but the sound insulation suffers. As noted above, sound waves penetrate through hard and solids. The profile is both solid and rigid, and is also attached tightly to the wall. Of course, it will very diligently transmit the vibrations emanating from the surface.

Just one small detail can correct the situation - a damping tape.

It costs a pittance, but its effect is considerable! The point is, when fixing the profiles, lay this very tape between them and the surface of the walls - this will not affect the quality of the fastening in any way, but there will be no direct contact, which means that the sound will be absorbed and reflected by the tape, and only the pitiful remnants of sound waves will pass to the profile.

This simple technique is, in fact, important to do when installing any structures to walls and ceilings. Are you covering your walls with plasterboard? Place tape under all contacts with the wall. Do you do slatted ceiling? Don't forget the tape! Small nuances can add up to significant results.

Insulation device - how to fill the void?

The structure of the stretch ceiling itself should make you want to soundproof it - there is so much left between the ceiling and the tension membrane usable space! In fact, you just need to competently fill the void between them. You will find a lot of materials for this, as well as manufacturers. Focus on the thickness of the empty space - if it reaches 5 mm or more, you can freely use mineral or fiberglass wool.

Cotton materials have the highest sound absorption coefficient - 0.75-0.95 (from 0 to 1). This is due to their heterogeneous structure and softness. The sound seems to get stuck between the fibers of the cotton structure. The same property is observed to a somewhat lesser extent in fibrous and porous materials. The stiffer the material, the worse it blocks sound - this rule also applies to soundproofing products. So soft cotton wool is the best option.

If the space between the ceilings is not so large, you can choose one of two options to solve the problem. The first is that you still allow the master to make the ceiling lower and fill the space with cotton wool. The absence of a chandelier will help visually make the room taller; fortunately, in our time, lighting hidden in special niches ceiling skirting boards, you won’t surprise anyone anymore.

If you don’t want to make such sacrifices, don’t. Yes, especially among modern materials. Their thickness can be only 5-10 mm, which is what you need. It can be semi-rigid pressed wool or polymer materials. Among them you will find composite panels - a combination of several materials with different structures. In any case, even if you decide to save space, try to combine thin materials. There is no need to use polystyrene foam or expanded polystyrene as sound insulation. Although they have a cellular structure, their sound absorption coefficient is not high.

Stretch ceiling with sound insulation - progress of work

So, you have decided on the material. It's time to start minor work - sealing gaps, cracks, holes. It is enough to fill small cracks with putty; larger ones should be filled polyurethane foam. If pipes pass through ceilings, the area near the ceiling must be insulated with a special acoustic sealant - to do this, remove a few centimeters of concrete around the pipes and fill it with sealant.

Among the soundproofing materials there are also those that are adhesive to the ceiling. This will save a lot of time, but if such insulation is not affordable, you can make a frame for soundproofing boards. Along the width of the slabs, attach to the ceiling (don’t forget about the damping tape!) a frame made of bars or plasterboard profile, and lay insulation boards between it. There should be no gaps or voids; you need to completely cover the entire ceiling area. It is clear that the bars and slabs should not extend beyond the profiles for the suspended ceiling; it is even better if there is an air gap between the sound insulation and the ceiling membrane.

Then all that remains is to stretch the ceiling, and it is better to entrust this work to professionals. By the way, among ceilings of this kind there are special acoustic stretch ceilings that have additional opportunity dampen and reflect sounds. They differ from ordinary canvases in that they have a perforated surface. Micro holes different forms allow the membrane to absorb sound waves well. However, this is not a panacea - it should still be used in combination with other soundproofing methods, and then the effect can be very significant!

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 tension fabrics:

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

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.

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 an apartment under a suspended ceiling is carried out as follows:

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

The new generation of rolled material is made without phenol, has the highest noise protection, and withstands moisture. Thickness 12 mm, contains no glue, used for frame and frameless stretch ceilings.

Advantages of Texound:

Resistance to temperature conditions. The material does not lose its quality indicators up to -20 C.
Increased elasticity - in this parameter the product is similar to dense rubber.
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 available in different sizes, complemented by 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 are applied insulating material. 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 construction hairdryer. 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 finishing 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:

Non-pressed foam plastic is marked PSB-S, produced from granules different sizes, which determine 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 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%.

IN apartment building It is difficult to protect yourself from sounds coming from all sides. The upstairs neighbors are especially annoying. They stomp, drop things, turn on music. All this at the most inopportune time. Therefore, a ceiling in the apartment is necessary. Especially if the height difference is significant, and the panel is supposed to be stretched at a distance of more than 50 mm from the rough base. Then it will play the role of a membrane, which will only enhance the “sound attack”.

Before choosing an insulator, you need to understand what kind of noise is causing trouble.

Two types of noise

Structural or percussive

Appear as a result of falling various objects, vibration, walking, moving furniture. Spread over hard surfaces.

Air

They are transmitted through the air and easily pass through porous or thin membranes. Represent speech, sounds made musical instruments, audio equipment, etc.

Each apartment has a different set of noises. It is important to understand their nature, only then can you choose the right insulation. In some cases it will not be needed, in others it is necessary. Under unfavorable circumstances, the canvas becomes a drum membrane, multiplying sound waves.

Why does the ceiling add noise?

The structure is fixed to the ceiling. The fasteners become sound bridges that transmit vibrations to the canvas.
The presence of significant voids in interfloor ceilings. These may be gaps, cracks, cracks, etc.
The distance between the rough base and the tension panel is more than 50 mm, which always happens with significant differences in height.

Hard

Solid slabs made of various insulators: pressed wool with porous inclusions, extruded polystyrene, panels filled with quartz sand.

For different types noise, various soundproofing coatings are chosen. When choosing, you need to take into account one pattern. As density increases, the sound absorption coefficient decreases. At the same time, dense insulators block low-frequency noise best, and high- and mid-frequency noise - worse.

Popular materials for arranging soundproofed ceilings

Mineral wool. Does not burn, does not rot, is easy to install, protects not only from noise, but also from cold. The price is low. Available in the form of slabs or rolls. Disadvantages: easily absorbs moisture, after which it loses its insulating properties. To obtain the desired effect, you have to lay a thick layer of cotton wool. It is not advisable to use it together with mortise ones to prevent overheating of the wiring.
Polystyrene. Moisture-resistant, lightweight, dense, especially extruded varieties. It comes in the form of slabs that are very easy to install. The price is low. Disadvantages: it burns with the release of toxic substances, the noise absorption coefficient is low. Especially in comparison with cotton insulators.
Acoustic membranes. Thin, flexible, yet dense. Holds sounds of low and high frequencies well. Do not burn, resistant to impact high temperatures, safe, environmentally friendly. Their main disadvantage is their high price.
Wood boards. They absorb various sounds well and, subject to special treatment, are resistant to moisture. Disadvantages: for high-quality sound insulation it is necessary to use plates of considerable thickness and weight.

Three ways to soundproof a ceiling

Installation of the selected ceiling soundproofing in an apartment under a suspended ceiling depends on its type. We'll take a closer look at three possible options.

Frame installation

The technique is used for laying rolled or slab cotton wool materials and is suitable for arranging multi-layer insulation. A significant plus is that the coating is placed “by surprise” and is securely held in the frame. Therefore, there is no need to drill the surface for additional fasteners. The system can be of any height; it holds even a heavy structure well. Significant disadvantages include the cost of money and time for constructing the frame.

To work, in addition to the insulating sheet, you will need either a block or a damper tape that will dampen impact noise.

Sequencing

Preparing the foundation. We remove the old finish from it, remove defects, cracks, if necessary. We remove dirt, dust, and treat with an antiseptic. We carefully process joints and corners. This is where mold appears before other areas.
Let's mark the base. We place marks on the areas where the fasteners of the future frame will be fixed. In order for the sound insulation to fit without gaps, we select for the guides a pitch equal to the width of the material minus 20-30 mm.
We cut out the guides. We saw off the bars with a jigsaw, and cut the profiles with metal scissors. To the reverse side metal parts glue the polyethylene foam tape.
Drill holes in the base. We fix the guides on the dowels. If the insulating mats are thick, the profiles for them are installed on suspensions with special acoustic decoupling.
We lay the plates apart so that they are well held in place. For multilayer structures, the rows are laid alternately. In this case, we make sure that there is a displacement of the seams. That is, the gaps between the tiles were in the middle of the slabs of the next row.

Multilayer systems can be laid in this way. The first row of frame profiles is installed along the room. It fits into it. On top of it, across the first row, a second row of guides is placed, into which the plates are also placed.

Glue mounting

Used for installing semi-rigid slabs with a density of at least 30 kg/cubic meter. m. Laying is carried out frameless method. Quickly, simply with a minimum of sound-conducting elements and gaps. Money is saved, as well as time for the construction of the sheathing. To secure the plates you will need glue on plaster or cement based, mushroom dowels, five pieces per element.

Sequencing

Preparing the foundation. We remove the old finish, if there was any. We seal all cracks, cracks, and other defects. We clean off dust and dirt. Prime the base with a suitable primer. This will make it possible to reduce consumption and improve its adhesion to the surface. Apply one or more layers and wait for complete drying.
Cooking adhesive composition. We dilute it with water in the proportions indicated on the package. You can stir the paste by hand, but this is time-consuming and ineffective. It is better to use a construction drill with a special attachment.
Lay the slab on level base. Using a spatula, apply a layer of glue evenly on it. Distribute it over the entire surface.
Place the insulating plate coated with the adhesive mixture in place and press firmly. We start laying from the wall. We fit the elements to each other very tightly so that there are no gaps.
We secure each plate with mushroom dowels. To do this, we drill five holes in each element. Their depth should be 5-6 cm greater than the thickness of the insulator. We make holes in the corners of the plate and in the center. We install dowels in them.

A layer of soundproofing coating underneath guarantees effective protection from noise. Provided everything is done correctly. This design is quite easy to assemble with your own hands, especially if semi-rigid slabs are chosen for installation. Properly executed sound insulation will last a long time; repairs will not be required during this period.

For apartment buildings One of the most pressing problems is good audibility between neighboring apartments. The peace of residents is often disturbed by too noisy or active neighbors, and apartment owners must control their behavior at all times in order to avoid scandals and complaints. Sound travels best through interfloor ceilings. Soundproofing the ceiling in an apartment under a suspended ceiling will help solve this problem.

The design of this finishing element itself provides for a certain level of noise attenuation. For example, lack suspended structure the fact that the sound is well conducted by the frame elements. The soft fabric of the stretch ceiling and the air gap between it and the floor slab can muffle the sound from neighbors by about 5 dB. If you use a special perforated film, which recently appeared in the arsenal of installers of such coatings, the effect will be more noticeable. True, the cost of finishing also increases significantly. You can save money if you additionally place accessible noise-absorbing elements under the film. Moreover, such a modernization of the ceiling in an apartment under a suspended ceiling can be done with your own hands without any problems.

Types of materials used for sound insulation

Sound insulation under a suspended ceiling can be done using various materials. Before stretching the stretch ceiling, you need to complete their installation. There are two types of materials:

They reflect sound waves, as a rule, have a solid mass and a dense surface - soundproofing materials.
Slow down the speed of the sound wave and dampen it due to large quantity pores – sound-absorbing materials. The rule here is: the thicker the coating layer, the better the noise-absorbing properties.

The best result is obtained by combining two types of materials. In this case, a kind of sandwich is obtained: a layer with sound-absorbing properties is covered on both sides with sound-reflecting elements.

Sound insulation of the ceiling under a suspended ceiling can be carried out using the following materials.

It is recommended to cover the structural elements of the frame in the area adjacent to the ceiling with a special damper tape. It will not allow sound to travel through profiles or sheathing beams.

Mineral wool loses its properties when exposed to moisture, so it is necessary to ensure good waterproofing ceiling at the top, and at the bottom there must be a vapor barrier membrane. A solid ceiling layer of mineral wool will reduce the height of the room by at least 10 cm.

If the first priority is to ensure sound insulation rather than insulation, then you should choose mineral wool with the appropriate properties. You can focus on the name: “Shumanet”, “Shumostop”.

Cork, wood panels

Acoustic membranes

Most modern look materials. They are distinguished by their excellent soundproofing properties, low thickness, environmental friendliness and fire resistance.

There are only two negative points: these materials have considerable weight, so it is preferable to mount them on a rigid frame, and they are quite expensive.

Acoustic membranes can be attached to the ceiling using special glue; there are also self-adhesive varieties of this coating. They can be used either in combination with other materials or as the only method of noise protection. It all depends on the characteristics of the room and the tasks being solved.

Preparatory work

The quality and durability of the ceiling sound insulation under the tension fabric will directly depend on the preliminary preparation of the base surface.

The old coating should be removed from the ceiling.
Carefully use special sealants.
It is imperative to apply a primer with antiseptic properties: after installing a stretch ceiling, it will be problematic to detect and remove mold or mildew that has appeared in time. The primer will also improve adhesion when gluing soundproofing materials.

Subtleties of sound insulation under a suspended ceiling

The variety of soundproofing materials gives rise to many combinations and designs of the soundproofing layer. Each design has its own fastening algorithm. But the following general points can be highlighted for everyone:

Sound insulation must be securely fastened to avoid any of its elements falling out onto the stretch ceiling.
Before installation, materials must be allowed to rest for at least a day in the room where they will be used.
The noise-absorbing coating should form a single plane that does not protrude beyond the level of tension of the canvas.

All joints between elements must be carefully sealed. When laying in two layers, they must be shifted relative to each other so that the joints do not coincide.

When installing acoustic membranes, such as, for example, Texound, adjacent layers are superimposed on each other. Then they are carefully trimmed with a knife, and the resulting smooth joint is sealed using a torch or a hair dryer.

Hygroscopic materials, such as mineral wool, must be reliably protected both from moisture from the outside and from water vapor from inside the room. Therefore, it is necessary to have waterproofing on the ceiling and a vapor barrier membrane between the material and the stretched fabric.
During installation frame structure it is necessary to cover its elements with self-adhesive sound-absorbing tape.
Before installing sound insulation, it is necessary to carry out all communications and remove fastening elements lighting fixtures. It is better to put the wires in special corrugations.

Please note that recessed ceiling luminaires do not combine well with mineral wool insulation. There is a high probability that they will overheat and often fail.

Mounting methods

Sound insulation can be attached in three main ways:

fit into the cells of the frame;
stick to the ceiling surface;
attached to special dowels in the form of mushrooms.

To be safe, it is recommended to combine these methods. So, if you are gluing slabs of material to the ceiling, then it would be useful to additionally secure them with fungi. Five pieces are enough: 4 are attached in the corners, and one in the middle of the slab.

Stretch ceilings are becoming more and more popular every year. This is a really easy way to create a beautiful, perfectly smooth surface. But soundproofing is theirs weakness: a stretch ceiling is not only a weak barrier to sound waves, but also often causes a drum effect: the stretched film acts like a membrane and increases the volume of sounds coming from the upper floors. To ensure that the installation of a stretch ceiling does not turn into disappointment, it is recommended that you first think about reliable sound insulation.

Sound insulation under a suspended ceiling in an apartment

Installing an acoustic stretch ceiling structure in an apartment is one of the most common ways to reduce noise levels in a room. An air gap is formed between the ceiling and the surface of the stretch ceiling, which significantly reduces the amount of noise. However, this is not enough to get rid of it completely.

Soundproof stretch ceilings in the apartment

To enhance the insulating effect, you will need to install special soundproofing material. Choosing from a variety of options, let’s take a look at some of them – Texound, Isotex, FonStar. Texaund - Spanish-made membranes - are dense, ultra-thin sheets with a felt coating. Finnish Isotex panels are made from wood fiber without chemical additives or glue. German cellulose boards VonStar contain a filler in the form of granular mineral used in water filters.

Soundproofing a stretch ceiling in an apartment

After consulting with experts and choosing the right one soundproofing material, you can proceed to its installation. Before this, it is necessary to seal the joints and cracks on the surface of the soundproof stretch ceiling, and also level it. Soundproofing stretch ceiling can be attached to metal profiles, and directly to the ceiling. The manufacturer informs you about the installation method. When attaching acoustic panels, it is important to use special vibration suspensions and anchors with a wide head. The next steps are installation of electrical wiring and the suspended ceiling itself. This is not an easy task and requires special skills. Therefore, you should entrust this stage to professionals. In order to achieve the maximum insulating effect, preference should be given not to ordinary stretch ceilings, but to those that have a perforated surface - a soundproof stretch ceiling.

Sound insulation under suspended ceiling.

In the process of repairing quartiles, citizens rarely think about sound insulation for suspended ceilings. As a result, this question arises after the renovation, when all the finances have already been invested and there is simply no energy left to redo it. However, the upstairs neighbors do not take into account the fact that your apartment has not had good soundproofing work done on the ceiling and continues to make annoying noise. In order to get rid of noisy neighbors, we wrote this article. In it you will understand in detail how best to carry out sound insulation under a suspended ceiling.

There are many things on the Internet that are not recommended for soundproofing stretch ceiling. As a rule, 90% of the information presented there is written by delitians who have never held a tool in their hands. Don't believe it.

For high-quality sound insulation, you must do the following:

If the suspended ceiling is already installed, it needs to be dismantled. During dismantling, the ceiling may rupture (if the ceiling has been installed for a long time, then the plastic has most likely already dried out and lost its elastic properties), areas in the corners are especially susceptible to rupture - they have the highest stress. Well, it’s okay if this happens, the ceiling canvas can be re-glued special glue. After dismantling the canvas, it is necessary to dismantle the baguette; there should not be any difficulties here. Next, we proceed to installation under tension. For soundproofing to work, you must follow the rules.

A soundproofing structure should not consist of the same type of material; effective soundproofing consists of a complex of such materials. This is an alternation of soft and hard material.

The tightness of the structure from an acoustic point of view must be ensured. Here we need mastic or sealants. The presence of rigid connections between elements is unacceptable. Sound tends to create vibrations, which leads to structural noise. To avoid this violation we use vibration suspensions. We also seal the construction seams between the materials with sealant or mastic.

To begin with, we assemble a frame from profiles 28*27 and a ceiling profile 63*27. A damper tape is glued between the frame and the wall (I remind you that we need to rid the frame of vibration effects - structural noise). As for the ceiling profile, it is mounted on vibration suspensions. Usually 4 pcs. per one square meter.

You can use any soft material of your choice. Fortunately, there is plenty of that on our Internet. This can be either ordinary mineral wool or a specially designed sound-absorbing k-fonik. If you are leaning towards mineral wool, then take mats with a density of up to 45 kg/m3. Soft material is necessary to absorb and dampen sound. Passing through it, the sound loses its original energy and goes out. After choosing a soft soundproofing material, all that remains is to fill the entire frame with it. Next, we mount the rigid material on top ceiling profiles. It could be like GVL sheets, and special wolf bavaria panels. The seams between the material are also sealed with sealant or mastic.

First, before attaching the panels, we apply sealant and glue the mesh to the frame. This is necessary to eliminate rigid connections between the panels and the frame. The panels are fastened with self-tapping screws. The screw caps are also sealed with sealant.

The final stage.

Installed sound insulation for suspended ceilings. The gap between the baguette and the soundproofing structure is 3.5 cm. The structure itself takes up 7 - 8 centimeters. As a result, you have an excellent soundproof ceiling that creates acoustic comfort in the room.

The sound insulation for the suspended ceiling is ready, you can enjoy the silence and beauty of your cozy nest
