Soundproof ceiling in the apartment under the suspended ceiling

Stretch ceilings are rapidly gaining popularity - they allow you to create perfectly flat surfaces with a high decorative effect. But here is an effective barrier to penetration of noise, they are not able to become - soundproof qualities of stretched PVC or fabric fabric are not large.

If the noise from the upper floors becomes a real problem, then before the start of the process should be treated complexly. This means that, along with the choice of decorative qualities of the future ceiling coating should be thought through and high-quality sound insulation of the ceiling in the apartment under the tension ceiling.

Today, there are many materials that can create silence in the apartment, and they are quite suitable for mounting on the ceiling. Some and from vukoisolators are quite popular and have been used for many years not only to reduce noise levels, but also to warm the surfaces, since they have the appropriate properties. In addition to them, completely new materials are also on sale, which are specially designed for effective sound insulation.

Sound insulation materials for the ceiling

Before considering various materials for noise insulation, it should be noted that in recent years there have been stretch ceilings, which also have the property to reduce the level of external noise. The structure of the canvas has finely perforated structure of acoustic type , due to which the absorption of sound vibrations takes place. Naturally, if you install only such a sheet without additional noise insulation of the overlapping surface, the effect will be far from complete, and therefore it is recommended to install the ceiling tension in combination with acoustic materials.

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

• Various types of mineral wool or modified sound - and heat insulators made on on its basis.
• Styrofoam, ordinary and extruded.
• Cork cloths and plates.
• Foam mats.
• Modern soundproof material on mineral basis " Texound ".

Whatever material is chosen for noise isolation, it is always necessary to prepare the surface of the ceiling for installation work and to install a framework for the tension web that will subsequently hide the construction of the soundproof barrier.

Surface preparation and installation of the framework

The installation of any sound-absorbing materials under the suspended ceiling can be done in various ways by the - by gluing, laying between the guide rails or fastening with the - "fungi" anchors. In some cases, it is better to use two locking principles, especially when the base of the ceiling is not perfectly even. For example, glued or installed between the guide plates are additionally fixed with - mounts "fungi".

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

• If the ceiling has a qualitatively painted surface, then the sound insulation can be mounted immediately. Such a surface does not require special preparation, and the role of the primer will be performed by the colored layer.
• In the event that the ceiling coating is damaged, it is better to completely or partially remove it.
• Then, on the surface is passed rigid brush to remove fine dust and dust that can prevent the gluing of plates or sheets.
• Further, comes priming the surface of the ceiling and walls by 100 ÷ 150 mm from their joint in 2 ÷ 3 layers. Each subsequent layer of primer is applied only after the previous one has dried completely. It is very important to work well the joints of the ceiling with walls and corners, as it is in these places that the spots of dampness and mold are most often present. For priming, special formulations having an antiseptic effect are used. Such a primer will create on the surface a stable film , which not only protects from the emergence of foci of microflora, but will also promote good adhesion of materials.

ceiling surface After the surfaces have been primed and dried, it is possible to proceed to fixing the guide profiles along the perimeter of the room for the installation of a stretch ceiling.

• For this, first of all, along the entire perimeter of the room, the height is fixed, on which the guides will be mounted. This process ss pr is carried out with the help of a building level and a painted marking cord on which an even line is repulsed on the wall. Instead of the build level for the line, it is better to use a laser level that will determine the boundary of the profiles fixing all around the perimeter of the room.
• The next step of the is the cutting profiles of the correct size.

• Since the profile is metallic and is a good noise conductor, the must be installed on the side that will be adjacent to the wall, before attaching the soundproofing tape to the .

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

• Next, the profile is pressed against the wall by the side with a glued tape and fixed on it with screws or dowels through the drilled holes.

Fastening is made in steps of 100 ÷ 150 mm. Such a frequent arrangement must be maintained, since fastening elements will have a very large load on these and from mass, and web tension force.

• Then, the installation locations of the lighting devices are planned. For them special areas are prepared and fixed, for example, from a bar, on which fixtures will be fixed. The thickness of the beam is selected depending on the distance to which the tensioning sheet will be lowered from the base ceiling base. The platforms should be level with the profile installed on the wall, or provide the necessary distance from the canvas, if the installation of recessed luminaires is supposed.

• After this, the electrical cable is connected to the mounting locations of the lighting elements. The cable must be reliably fixed on the ceiling or on wooden elements - its sagging is not allowed.
• Further, fastening elements are installed on the mounting locations of the luminaires, which are included in the kit, so that after the tension of the cloth, the auxiliary parts of the devices are under it.

Now can switch to soundproofing. They may vary - depending on the material selected.

Sound Insulation Features and Technologies Now, knowing how to prepare a ceiling for its sound insulation and install a framework for a stretch ceiling, you can go to the materials. To determine the choice, you should consider their characteristics and installation methods.

Mineral wool

materials Mineral basalt wool is most commonly used for heat and soundproofing works both on ceilings and on walls. It has good performance and is most suitable for living quarters of all similar fibrous materials.

But it is better in our case to take not an ordinary stone wool - today we are producing advanced types of this material, and their names directly indicate their purpose. This is, for example, " Shumanet BM " or " Noisy " C2 and To 2.

• " Shumanet BM"

This material consists of basalt fibers and is characterized as sound absorber premium. One side of the mats is reinforced with a layer of fiberglass, which makes the surface more rigid , and the inner porous layer is well protected. This rigid "cover" keeps the plates intact and not the gives the them to deform, and also prevents small particles from entering the room through a perforated tension web.

Packaging of panels "Shumanet"

Characteristics of sound-absorbing panels " Shumanet BM" complies with the requirements of SNiP 23 ÷ 03 ÷ 2003 "Noise protection".The main ones are listed in the table:

Material characteristic name	Parameter value
Standard plate size, mm	1000 × 500;1000 × 600
Plate thickness, mm	50
Density of the material, kg / m³	45
Number of plates in the package, pcs.	4
Area of ​​plates in one package, m²	2.4
Weight of one package, kg	4,2 ÷ 5,5
Package volume, m³	0,1 × 0,12
Sound absorption coefficient( average), dB	23 ÷

water absorption by partial immersion in water for 24 hours	not more than 1 ÷ 3%

Prevalence nt ulcers ukopogloscheniya defined for special acoustic tests, conducted in the laboratory NIISF RAASN in Moscow. This material has a low percentage desiccation , so it can safely be used in rooms with high humidity.

• « Noisy »

Fiberglass panels «Noisy»

Another with one material for a soundproof covering of the ceiling is « Noise-locker ».It is produced in two varieties and is labeled With 2 and To 2. Therefore, if sound absorbing plates are selected, special attention must be paid to the marking:

Material characteristic name	Parameter value
C2	K2
Standard plate size( mm)	1250 × 600	1200 × 300
Plate thickness( mm)	20
Density of the material( kg / m³)	70	90-100
Number of plates in the package	10
Area of ​​the plates in one package( m²)	7.5	3.6
Weight per package( kg)	11	8.8
Packing dimensions( m³)	0.15	0.072
Sound absorption coefficient average,( DB)	26-27	20
Combustibility( GOST 30244-94)	NG( non-flammable)
Water absorption at partial immersion in water for 24 hours	Not more than2%	No more than 3%

- C2 is most often used for insulation and soundproofing of floors, because it is made from hydrophobic staple glass fibers.

- K2 is used for all surfaces. It is made from basalt fibers, and usually it is this " noise-stop " used for soundproofing ceilings.

Often these materials are used in a complex, since With 2 has a higher coefficient due to absorption, and to 2 is less harmful to human health. Therefore, the first layer is fixed glass fiber plates, and from the top they are covered with basalt mats. With this use, they can reduce the noise level to 46 DB .

Installation of mineral wool soundproofing boards

The installation is carried out in the following order:

• If noise isolator is planned to be laid between the guide rails , then the is first marked with on the ceiling on the ceiling. Having determined the reference points for the arrangement of all elements, lines are broken off, along which the guide rails will be fixed. These elements are fixed at a distance of 550 ÷ 600 mm from each other, depending on the width of the selected sound absorbing plates.

Laying soundproof panels between the batten rails

For the frame, a wooden beam or metal profile can be used. The guides should not have a thickness that lowers them below the of the anchored on the profile walls for the tension web.

If metal profiles are used for the of the crate, they must also be glued with a special tape, otherwise the effect of will be reduced.

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

This option is acceptable in the case if the apartment has a high ceiling and plans to lay a thick layer of soundproof material. This should be anticipated in advance, still when securing profiles for a stretch ceiling.

• The next step of is the assembly of acoustic material boards. They should be as close as possible to the ceiling surface. If the sound insulator fits into the crate , then it is recommended to fill with its for the entire thickness. The material must be laid between the elements of the frame.
• If the crate is not installed, then for reliable connection soundproof slabs with a ceiling one of the adhesive compositions is used. This can be an adhesive in the spray form, which has recently been increasingly used for mounting. Another option is mounting glue on cement or gypsum basis.

Application of

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

- For example, if the ceiling is concrete, then glue can be used on a cement or gypsum basis. For mounting on the painted surface, it is better to choose a glue spray that perfectly fixes the mats on the ceiling, without additional fixation by "fungi".Spray the adhesive best in the open air, for example, on the balcony, and then immediately put the mats and fix them to the ceiling surface.

Fixation of glued blocks on the ceiling

- If a glue based on gypsum or cement is used, it is necessary to additionally fix the mats with - fasteners, for which directly through the soundproofing mats, through holes in the ceiling with depth 50 ÷ 60 mm.

Glue spreading on cement or gypsum basis

For each of the mats, it will be necessary to use five to six

fastening elements to fix .

Additional fixation with dowels "fungi"

If a perforated sheet is used as a stretch ceiling, on its is covered with a vapor barrier on top of the room and is fixed with fixings - "fungi".

• Sound insulation between elements, , , is covered with a membrane and fastened to bars using staples and a stapler, and to metal profiles - with double-sided tape or - to the ceiling using "fungi".

Protective vapor barrier membrane on top of

mats After to Lei, if used, it will completely dry out, you can proceed to the installation of the stretch ceiling.

Use of EPS polystyrene panels

For sound insulation of the ceiling surface, different types of expanded polystyrene are used, which is produced in a convenient form for installation in the form of slabs of different sizes. Their thickness can be from 20 to 100 mm.

There are two classes of this material - conventional, non-pressed polystyrene( it is usually called polystyrene) and extruded. Their characteristics vary among themselves according to most parameters:

Comparative characteristics of expanded polystyrene and extruded polystyrene at an average thickness of 50 mm
Characteristics of the material	Extruded polystyrene foam	Polyfoam
Water absorption in% by volume for 30 days, no more	0.4	4
Water absorption in% by volume for 24 hours, no more	0.2	2
Vapor permeability, mg / m × h × Pa	0.018	-
Thermal conductivity in dry condition at temperature( 25 + -5), W /( m × OS) not more than	0,028 - 0,03	0,036-0,050
Sound absorption coefficient, DB	23-27	42-53
Strength limit for static bending, MPa	0,4-1,0	0,07-0,20
Compressive strength at 10% linear deformation, MPa, not less than	0,25-0,50	0,05-0,20
Density, kg / m2, within	28-45	15-35
Operating temperature range, оС	-50 to +75	-50 to +70
Flammability	From G1( moderate combustibility) to G4( combustible)

non-compressed

polystyrene This class of material is marked PSB-C , that is, self-extinguishing polystyrene foam, non-pressed .

Polystyrene panels PSB-C

Polystyrene consists of different sizes of - granules and the density of the material that directly affects its sound-insulating properties depends on it.

For the insulation of the ceiling, it is better to use a foam having a low density, since the material is lighter in weight and lower in thermal conductivity. The density itself will be prompted by the marking itself - so, for the ceiling mounting, the is good for the PSB-C 25 or 35.

The foam is well attached to the surface, provided the glue is correctly matched for it. Usually, cement-based compounds, "liquid nails" or assembly foam are used for fixing. As an additional fixer to the ceiling surface, the - "fungi" attachments are also used.

• Extruded EPS polystyrene

This material has a higher density, because it is extruded by squeezing molten mass under pressure through the forming nozzles.

Extruded polystyrene foam board

The plates of this material often have a "lock" part of the spike groove or of the , slats that guarantees the creation of a seamless surface, and in turn, increases the heat and soundproofing qualities of the created layer. Styrofoam with a thickness of 20 mm is able to dissipate the impact noise and reduce the effect of it by 20 ÷ 27 DB , and this parameter increases with increasing thickness of the material.

For mounting extruded polystyrene foam , the same compositions are used as for non-pressed foam.

The advantages of both types of expanded polystyrene for ceiling mounting include:

- Light weight, which guarantees the reliable mount on the horizontal surface of the ceiling.

- Mold resistance.

- Low coefficient of t t conductivity.

- High enough level of sound absorption.

The negative qualities of this material, for its use in residential premises, can be called:

- The material is flammable, and during combustion emits with smoke hazardous for the life of of a person substance. In addition, melting, it spreads, transferring the fire to closely located surfaces and objects.

Polyfoam is unsafe in terms of flammability and toxic smoke

- Any styrofoam does not tolerate UV light.

- With prolonged use, the material begins to decompose independently, releasing hydrocyanic acid, hydrogen halides , nitrogen oxides and other dangerous compounds. To a greater extent is subjected to this phenomenon when the non-pressed polystyrene is exposed.

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

Installation of any type of expanded polystyrene occurs identically. On its surface is applied one of the selected adhesive compositions, and the plate is pressed against the ceiling.

Styrofoam plates fixed to the ceiling surface

Then through holes are drilled, and through them the fastenings - "fungi" are driven into the capital ceiling. Usually for a plate, planted on the glue, only two fasteners are sufficient.

If this method is chosen, it should be clearly understood that the simplicity of installation does not justify the very low soundproof properties of this material. The effectiveness of such protection against noise is more than doubtful.

Sound insulator Texound

Texound has recently appeared on the Russian market and therefore the still did not have time to gain due popularity, as not many of them know the advantages of this material before other soundproofers. The most important thing about is its dignity, especially for apartments with a small footprint and low ceilings - a small thickness that does not completely conceal the area, unless, of course, " Texdown " is used in combination with other materials.

The roll of the modern noise isolator - Texunda

" Texdown ", despite its small thickness, has a very high density, and is able to dissipate and absorb sound waves of high intensity. Such a coating not only protects the room from unwanted noise from outside, but also does not allow sound waves that form inside the apartment to go beyond the its limits.

" Texdown " is available in rolls or sheets, packed in polyethylene. The main characteristics are given in the table:

Material characteristic name	Parameter value
Material density( kg / m³)	up to 1900
Sound absorption coefficient( average)	25 ÷ 30
Combustibility( GOST 30244-94)	G2
Tensile elongation,%	300
Production materials	mineral aragonite, plasticizers, polyolefins, spunbond

In addition, Texound has the following qualities:

• Resistance to temperature changes - it does not lose its original qualities even with freezing up to - 20 ° C .
• The elasticity of the material makes it similar to dense rubber.
• The material is impervious to moisture and has strong antiseptic properties, so mold will never appear on the on it .
• The operating period of the material is unlimited.
• " Texdown " fits well with other heat and soundproof materials, complements and enhances their effect.

« Texdown » is produced in different sizes. Can have conventional and self-adhesive surfaces, felt or foil padding:

Mounting " Texound "

" Texound " can be fixed on any substrate, whether concrete or wood, plasterboard, metal, plastic and other surfaces, the main thing is that they are prepared for its installation. Preparation is the same as for any other soundproof material.

" Texdown " is installed as a single sound absorbing material or in combination with other heat insulators.

First installation option

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

Adhesive "Texdown" on the ceiling surface

• Adhesive is applied to the surface of the material and walls, then pauses for 14 ÷ 20 minutes, and only then the Texaunda "is pasted onto the ceiling.
• Since the material has a sufficiently large weight, it is glued in small sheets.
• Cloths are pasted overlapping to 40 ÷ 50 mm. After the overlapping installation, a smooth cut is made, then the edges of the sheets are combined and welded together with warming up with using the building hair dryer or gas burner.

Welding of joints of material

• Some masters prefer to glue the canvas with "Hermetic" or "Liquid nails" glue.
• Self-adhesive " Texound " mount completely just , so the to the layer on one side of it is it is put - it is necessary to remove the protective film , to press to the surface and fix the material on the ceiling.

Convenient in the work of "Texdown" with the already applied adhesive layer

• After mounting on the adhesive of the canvas, it is necessary to fix the - with "fungi", which are placed at a distance of 350 ÷ 500 mm from each other.

Additional fixation with dowels "fungi"

The second variant of installation

This variation nt pr and the installation of a false ceiling includes several operations. They are carried out before fastening the guides for the tension ceiling. Of course, such an approach is possible only at a sufficient height of the room.

• Ceiling is installed on the ceiling , mineral wool slabs are laid - according to the technology described above.
• Then on sheets of gypsum cardboard, having laid them on a desktop, " Texaunda " are pasted.

"Texund" is pre-glued on the sheets of gypsum board

• The next step is the drywall with sound insulator is mounted on the crate with self-tapping screws in steps of 100 ÷ 120 mm.
• Joints between the webs are welded with hot air or glued together by the "Sealant".
• After the installation of the drywall, you can proceed to install the guides for the tension ceiling.

The third variant

• In this variant Texound "is glued to the ceiling, as in the first installation method, fixed with" fungi ".
• After this, a frame made of metal profile or beams is mounted on the suspension or directly on the ceiling.

If a wireframe construction is required, it can be fixed after the finishing of the ceiling with the "tessound"

• . Further, between its guides one of the types of mineral wool - is laid: it can be " Schumanet " or " Noise detector ".
• On top of the frame it is desirable to cover with plasterboard, and only then go to the operations for installing the tension ceiling.

Sound insulation of the ceiling with acoustic foam rubber

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

As is known, foam rubber has a porous structure that is able to dissipate vibrating waves and absorb vibrations. Vibrational waves are particularly noticeable in panel houses, since concrete walls have a metal reinforcement, which is a good conductor for low and high frequency sounds.

Acoustic foam mats

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

Foam mats are very light , so they can be glued to any surface with conventional silicone or even a double-sided mounting tape.

When using this material without additional finishing, you can choose a color solution that will match the color scheme of the entire interior, as it produces 10-12 matt colors. Under the suspended ceiling, you can not think about the color solution and purchase a more affordable acoustic foam - white or gray.

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

The relief of acoustic foam

The reliefs of foam rubber have their names, corresponding to the picture - they are "Wedge", "Pyramid" and "Wave"( egg tray).In addition, foam rubber elements are produced, having a special shape, designed to neutralize the propagation of low-frequency sounds.

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

Installation of foam insulation

Fixation of mats on any surface can be called the simplest of all installation works associated with the installation of soundproof materials. Foam can be attached to heated silicone, to glue spray, "Liquid nails" or double-sided adhesive tape.

Spray adhesive

If the mats are to be closed, for example, with gypsum boards, the will have make the skeleton board , and the mounting process in this version will consist of the following steps:

• Foam can be glued to any surface,, that it was dry and clean.
• Mats are glued to the wall with one of the selected glue compounds. It is very important that the soundproof material is snug against the surface. The glue can be applied pointwise or sprayed over the entire surface of the mat.

Adhesive foam with silicone thermo-pistol

• Then, the foam is firmly pressed against the ceiling and stays for a few seconds.
• Next, next to it is mounted the next mat - and so the entire surface of the ceiling is filled.
• Then, on top of the foam, in the recesses of its relief, the elements of the are installed, 550 to 600 mm apart - this parameter will depend on the width of the drywall sheet, since they should find the at their edges half the widthbar or metal profile.
• After installation of all rails, electrical wiring is mounted, and drywall sheets are fixed on top of the of the crate.
• Next, comes installation of the frame under the suspended ceiling.

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

Another simpler and more affordable option is to glue the pore on the ceiling, and then immediately - install a skeleton for the tension ceiling, install the lighting fixtures and of the fastening elements for them.

Upon completion of the soundproofing work, you can proceed to install the tension ceiling

If the goal is to isolate the ceiling from the penetration of external noise, then from

's material above you can choose most affordable and self-installing.

In conclusion, it is necessary to note - in order to achieve the maximum effect of room noise insulation, it is necessary to cover one of acoustic materials in the room, including walls and floor, as the reinforcement belt very well transfers sound from one plate to another. Fixing soundproofing plates only on the ceiling, you can only slightly reduce the noise coming from above.
