Interroom wall insulation in a wooden house. Soundproofing walls in a wooden house

The advantages of a wooden house over stone buildings attract more and more people to such buildings. An environmentally friendly, warm and comfortable house that retains heat for a long time is an indicator of the refined taste and a certain wealth of its owner. In addition, a wooden house is not electrified, and dust is practically not collected in it. However, soundproofing is always necessary for a comfortable stay.

What is soundproofing for?

Along with a lot of advantages, wood is an excellent conductor of sound, and the structure of it has many resonant frequencies, at which the sound is amplified several times. This property of wood products is used in the creation of musical instruments, the manufacture of special resonant panels for concert halls.

However, in a built wooden house, a huge number of sounds amplified by resonance, and even those that are simply transmitted through the walls without amplification, will cause a lot of trouble to the owners who want to relax in silence. That is why, when building wooden houses, the need for soundproofing with the use of modern materials must be taken into account.

It should be borne in mind that according to the principle of implementation, two main types of sound insulation are distinguished:

• soundproofing is the implementation of a number of measures to reduce the penetration of sounds from the outside into the living space;
• sound absorption - taking measures to reduce the passage of sounds from the room to the outside.

When planning soundproofing measures, the permissible noise level requirements should also be taken into account. In particular, for residential premises, the maximum daily level is set at 40 dB, and during the day 30 dB. This level can be measured with the help of special devices - sound level meters. Increasing the level of sounds (noise) above these limits significantly reduces the comfort of staying in the room, and the level of 120 dB is already dangerous for the hearing organs.

When clarifying the factors affecting the noise level in the room, it should be taken into account that:

• whispering creates a sound level of 20 dB;
• quiet speech - 40 dB;
• noise from a passing car - about 80 dB;
• music player - an average of about 90-100 dB;
• fireworks and firecrackers - up to 130 dB.

Types of noise

Before planning measures for soundproofing, it is necessary to take into account the main sources of noise and the types of noise from which it is necessary to protect the interior of a wooden house. External noise can be divided into several types.

Acoustic

These are sounds that propagate through the air and are acoustic waves. The sources of such noise can be both the conversations of neighbors and the working audio equipment (players, tape recorders, amplifiers, radio tape recorders, TV), the sounds from the operation of car engines, the voices of animals.

Drums

This kind of sound is transmitted quite well and far directly by solid bodies, to which shock or vibration is applied. Such sources include, for example, perforators, hammer blows, the clatter of walking people, the sound of objects falling on the floor, the sound of a train moving along the rails.

Combined noises

This is the presence of noise, both acoustic and percussive. For example, the same perforator creates two types of noise. When the nozzle is exposed to the surface, frequent impacts are created, and from the operation of the perforator engine - acoustic noise.

Thus, when carrying out sound insulation, it is necessary to take into account which particular sources of noise are nearby, and from which type of noise it is necessary to isolate the room. In addition, the intensity of the sound (its loudness) should also be taken into account.

Types of sound insulation and its installation

First of all, for effective sound insulation, it is necessary to eliminate sound bridges in the room, which occur at the junctions of wooden parts and beams. Sounds are transmitted through these bridges very effectively, in addition, additional resonant frequencies arise in these places, at which the sound is amplified.

When soundproofing rooms, various materials and compositions are used, such as stitched mats, ready-made slabs of various materials, rolled sound insulation, liquid compositions applied by spraying.

The use of one or another material depends on the type of construction of the walls, floor and ceilings of the room. So, in case of a frame design, it is necessary to fill the inner part of the wall with special soundproof materials, and in this case the wall consists of three parts (two outer covered and inner soundproof).

• In the case of limited thickness between the outer parts of the wall, they are used as a sound and heat insulator. foam polyethylene or polyurethane.

• To reduce sound transmission between the wooden parts of the house, apply glass wool soundproofing and other materials. They are placed between beams and joists, eliminating direct contact between the wooden parts of the structure. And also to reduce the level of sound transmission and vibration, the beams are wrapped with special construction felt, and a polypropylene or cork substrate is placed under the floor. Such work is carried out even during the construction of the house, since later it will be difficult to complete them.

• Very simple but very effective is flooring in places of emphasis on sound insulators without rigid attachment to the base. Thus, a "floating floor" is obtained, not connected to the rest of the structure. This provides very high quality sound insulation. And the option of fixing floors on damper support springs or brackets is also used, which requires the use of special springs (brackets) designed for a large load. In this case, the load is calculated based on the total weight of the floor with furniture plus the weight of several people (depending on the area of ​​\u200b\u200bthe room).

• For additional interfloor noise and heat insulation between the ceiling and the floor of the next floor, most often expanded clay crumbs fall asleep. It is lightweight yet does its job well. Sometimes sand is also covered, but at the same time it is necessary to significantly increase the overall strength of the structure, given that the total weight of the structure will increase, use stronger materials for the ceiling. In order to reduce the total weight, leaves or dry sawdust are added to the sand.

You can start soundproofing with your own hands, gradually applying certain methods.

In particular, you should start with carefully sealing all the cracks through which sound passes, with special mastic or putty. The voids made for the installation of electrical switches are filled with mounting foam. Seal the entrances of water and gas pipes to the house using elastic sealants.

In the implementation of interior soundproofing, soundproofing materials are placed in the voids of wall partitions. Often, sound insulation is combined with thermal insulation by using heat-insulating materials lined with drywall.

In general, the sound insulation of walls in a wooden house requires an integrated approach with the elimination of all possible sound conductors in the room. At the same time, the location of air ducts is also taken into account, which, especially made of wood, are excellent conductors of sounds both inside the room between rooms from neighbors, and outside - into the room.

Cork soundproofing known for a long time, it was used in the construction of various houses and buildings. For example, on the Black Sea coast in Gagra (the former name of Gagra), a small castle was built especially for the rest of the members of the royal family, in which cork slabs were laid in all walls and doors in order to increase the efficiency of sound insulation. Thus, the sounds from the outside practically do not penetrate into the rooms of this building.

Currently, cork wood panels are also used for interior decoration. Such panels, in addition to excellent appearance, successfully perform the function of soundproofing. Cork wood soundproofing membranes are used not only in home decoration, but also in the construction of professional recording studios, where high-quality soundproofing of the room where sound is recorded is essential for obtaining high-quality sound.

As well as the soundproofing of a wooden structure can be performed using modern special liquid adhesives. At the same time, the quality of sound insulation is at a fairly high level.

Very often, foam, polyurethane and other materials are used for soundproofing, which quite successfully absorb a sound wave, are not subject to corrosion and are very durable.

If you had time to read something about soundproof linings, you noticed that the airborne noise insulation index Rw with all its pluses and minuses is given as the main acoustic characteristic of building structures. The fact that for the structures of interfloor structures in the building regulatory documentation, one more soundproofing indicator is additionally introduced - the index of the reduced impact noise level Lnw, indicates that the problem of providing the required soundproofing of floors is at least twice as complicated. This is confirmed by practice - according to statistics, more than half of residents' complaints about increased noise can be classified as "noise from neighbors from above", the reason for which is precisely the insufficient level of insulation of the floors.

Standards for soundproofing floors. Soundproofing characteristics of the main existing floors

The main regulatory document regulating the soundproof properties of building structures is currently the updated version of SNiP-23-03-2003 "Protection from noise". According to this SNiP, the index of airborne sound insulation by a floor between two apartments should not be lower than Rw = 52 dB, and the index of the reduced impact noise level under the floor should not exceed Lnw = 60 dB.

The amount of airborne sound insulation required is relatively simple. In mass multi-storey construction, this issue has long been solved by the production of prefabricated reinforced concrete elements or the implementation of monolithic ceilings of the required surface density and thickness.

For hollow core reinforced concrete slabs with a thickness of 220 mm and vibropressed reinforced concrete slabs with a thickness of 160 mm, the insulation index is approximately on the verge of Rw = 52 dB.

But for structural slabs with a thickness of 140 mm, of which, for example, a significant part of the housing stock was built in Moscow, the airborne noise insulation index rarely exceeds Rw = 51 dB. And this despite the fact that the SNiP introduced back in 1977, however, like the current SNiP, updated in 2012, sets the value of the airborne sound insulation index with an overlap of at least Rw = 52 dB!

One way or another, the soundproofing ability of a structure in relation to airborne noise is formed at the stage of prefabrication of building elements. And if the density of concrete during manufacture was not significantly violated, depending on the choice of a particular structure, it is possible to predict its sound insulation with a high degree of confidence. The task of builders in the field of airborne sound insulation is to ensure that during the construction of the building, they do not additionally spoil it through numerous gaps between the slabs or unsealed technological holes (for example, for heating pipes) in the wooden floors between the apartments of the house. At present, during the construction of "elite" monolithic housing of category A, the thickness of interfloor structures can reach up to 250 mm. In this case, the airborne noise isolation index turns out to be equal to Rw = 55 dB and higher.

At the same time, when the house has already been built, it is hardly possible to reduce the thickness of the bearing slabs without a major overhaul. Thus, if during the construction of a house a good indicator of airborne sound insulation was obtained, then it is likely to remain so, at least for the coming years (until the formation of through cracks).

With the provision of the required impact sound insulation - an indicator of the level of reduced impact noise under the ceiling - the situation is much worse. Firstly, what kind of insulation will be obtained: good or bad, is almost entirely determined on the spot by the direct executors, i.e. builders. Secondly, no one can guarantee that the new tenant will not destroy the additional soundproof structure on top of the structure slab during the subsequent repair, thereby drastically worsening the impact sound insulation.

The point here is the following: although the magnitude of impact noise insulation is determined by the massiveness of the structure, however, even with a one and a half meter thick floors (which is typical only for bomb shelters), it still does not meet the regulatory requirements. For example, the already mentioned monolithic reinforced concrete floor with a thickness of 250 mm has a reduced impact noise level of about Lnw = 74 dB. This value seriously falls short of the requirements of the current SNiP, where the impact noise level should not exceed Lnw = 60 dB.

It is necessary to say a few words regarding the standard itself and the methodology for assessing the level of impact noise. If the increase in the Rw index indicates an improvement in the sound insulation characteristics of the structure, then with regard to impact sound insulation, the situation improves if the value of the noise level under the floor becomes lower. When conducting acoustic tests in a special chamber, a so-called "poplar" machine is installed on the ceiling from above, which threshes on the floor with specially calibrated hammers at a given frequency. The sound level generated by the machine, measured in the room below (corrected for measurement standardization) and represented by a single number, is called the normalized impact sound level. Thus, the lower this index, the better the design from an acoustic point of view.

Increasing impact sound insulation by overlapping from the side of the room above (floor soundproofing)

If the level of airborne sound insulation is determined primarily by the massiveness and thickness of the floor slab itself, then with regard to impact sound insulation, the problem is always solved by additional structures. Reducing the level of impact noise is carried out either by installing an additional floor structure on an elastic base on the carrier plate, the so-called. "floating floor", or the use of materials with their own high impact noise reduction rates (linoleum, carpet, etc.) as a finishing floor covering.

An uncoated reinforced concrete slab with a thickness of 140 mm has a reduced impact noise index of about Lwn = 80 dB. In contrast to the "missing" to the norm in the case of airborne noise of a couple of decibels, here the difference with the maximum permissible value (Lwn = 60 dB) is as much as 20 dB. This approximately corresponds to the case when a neighbor from above laid ceramic tiles directly on the ceiling. At the same time, absolutely all movements from above become audible in the lower room.

The option, when a piece parquet floor is laid on a slab without any soundproofing measures through a sheet of plywood, firmly takes second place on the pedestal of the nightmares of the lower neighbors. It should be noted that the situation with parquet boards widely used on the market is much better from an acoustic point of view. According to the laying technology, an elastic layer must be laid between the base (floor slab) and the board itself. Depending on the sound insulation performance of the elastic layer, good performance can be obtained in terms of impact sound insulation. For example, the use of Akuflex rolled material with an impact sound insulation index Lnw = 20 dB as a substrate for a laminate with a thickness of 8 mm makes it possible to meet the requirements of building codes (Lnw = 60 dB) in the case of a reinforced concrete structure 160 mm thick.

However, the most effective method of dealing with impact noise in a wooden house is to use the following floating floor design (Fig. 1). A layer of elastic soundproofing material is laid on the slab, on top of which a leveling screed is arranged. At the same time, the edges of the soundproofing material should be led onto the walls around the entire perimeter of the room to be insulated so that the screed does not have rigid ties along the contour of the so-called. "sound bridges", the presence of which leads to a significant reduction in the effect of soundproofing floors.

To enhance the effect, Shumostop boards can be stacked in two layers.

You can also look at the instructions for installing a soundproof floor using Shumostop-C2, K2:

During the construction or renovation phase, there are two dangers to a successful impact sound insulation installation. The first is that sound insulation in a wooden house will not be performed at all, considering these costs as unnecessary. In the case of a single owner of a single apartment, the argument is: "I'm not rich enough to pay for the rest of my neighbor from below."

The second danger is that sound insulation will be performed, but with sound bridges. Unfortunately, even where far-sighted designers and investors have provided for a competent floor arrangement, there will always be a negligent foreman who did not explain to the workers the meaning of this event. As a result, it is often necessary to hollow out the screed around the perimeter of the room in the hope of obtaining the planned effect.

To date, there is a huge selection of materials on the market that can be used with greater or lesser success under the screed as an elastic layer. These are all kinds of materials based on expanded polyethylene foam (PPE), cork, rubber, needle-punched glass and synthetic fibers, mineral and glass wool.

Among this set, I would like to highlight several materials that have the highest acoustic properties. First of all, these are Shumostop-C2 and Shumostop-K2 slabs with a thickness of 20 mm. When a screed with a surface density of at least 80 kg/m3 is installed over them, the impact sound insulation index of this design is Ln,w = 39 dB. This allows you to meet the most stringent impact noise requirements with a large margin for any thickness of the structure's base plate. For example, the sound of a glass bottle breaking on the floor in the lower room is perceived as the fall of a light coin. The advantages of this design include the fact that it also protects against airborne noise (ΔRw ~ 8-10 dB).

For uneven wooden floors, the Shumoplast leveling mixture is well suited, which is laid on the ceiling under the screed over the entire area of ​​​​the floor of the protected room and is wound vertically on the wall to provide acoustic decoupling of the screed from the walls. With a mixture thickness of 20 mm, it allows you to level local unevenness of the floor surface and the remains of construction debris up to 10 mm in caliber, reduce the level of impact noise by 28 dB. The design using this material also protects against airborne noise (ΔRw ~ 7-9 dB).

To achieve the normative values ​​​​of sound insulation of wooden interfloor ceilings in terms of impact noise, it is often sufficient and significantly less thick (3-5 mm) rolled materials, for example - Shumanet-100, Shumanet-100Combi or Shumanet-100Hydro, which are also placed under the screed.

It should be noted that all the mentioned materials, especially with their small thickness, are exclusively impact sound insulators. Their ability to reduce noise in the downstairs room only becomes apparent when used as a resilient pad in a floating floor structure. The use of these materials to increase sound insulation in a wooden house by applying them to the ceiling or walls from the side of the lower room is devoid of practical meaning.

To protect against impact and airborne noise in a wooden house, prefabricated floor structures using ZIPS-POL panels (Fig. 2) also work effectively, providing impact noise insulation index in the range from 32 to 38 dB and additional airborne sound insulation 6-9 dB. The advantage of such structures is the simplicity and speed of installation. At the same time, for their successful application, an absolutely even, pre-prepared floor surface is required.

Increasing the insulation of airborne and impact noise by overlapping from the side of the underlying room (ceiling soundproofing)

The problem of increasing the insulation of wooden floors from the side of the underlying room is extremely relevant both in the case of airborne noise and in relation to impact noise.

When two vertically located premises (apartments) belong to different owners, it is often impossible to agree on the joint performance of soundproofing work. And since the neighbor below always suffers from impact noise, it is he who will have to pay for someone's negligence. At the same time, it is important to realize that those 20 dB of IMPACT noise reduction, which could easily be obtained by installing a floating floor on the side of the upper floor, cannot be made up by any means from the side of the lower floor. Practice shows that the effectiveness of soundproofing measures "from below" due to ceiling height restrictions and the requirements for the complexity of soundproofing measures rarely exceeds 18 dB.

In cases with noisy premises located on the first floors of residential buildings - cafes, restaurants or shops - an inverse problem arises. It is required to protect the upstairs living quarters from loud sounds (airborne noise), especially at night. Also, when arranging a recording studio or any other room where complete silence must be ensured, the wooden floor must be additionally insulated. And for noise of any type.

To date, one of the most effective designs of additional noise insulation of the ceiling is considered to be a frame ceiling on vibration suspensions, the thinnest solution with which (115 mm) is shown in Figure 3.

Such a design, thanks to the use of ceiling vibration suspensions Vibroflex-Connect PP, allows to achieve an increase in the value of the airborne sound insulation index by 17-19 dB. By replacing vibration isolating suspensions with more efficient ones - Vibroflex-K15, you can get 19-21 dB.

Let's consider a special case. The restaurant is located on the first floor of a residential building. The measured index of airborne sound insulation by the original structure, which is multi-hollow reinforced concrete slabs with a thickness of 220 mm, was Rw = 48 dB (calculated value Rw = 52 dB). According to the current SNiP, the airborne sound insulation index by the overlap between residential apartments and restaurants located below should be at least Rw = 57 dB. According to our practice, the airborne noise isolation index, where neighbors from above really stop writing complaints about the establishment, is at least Rw = 65 dB. Thus, with the help of the false ceiling design, it is necessary to add at least ΔRw = 9 dB, and preferably all 17 dB. It is not difficult to make sure that the design described above solves the problem with a margin.

The above scheme for additional noise insulation of the floor with some changes (as a rule, an increase in the ratio of the skin to the floor up to 200-300 mm) is also used in the construction of studios, concert halls and cinemas.

Our video will help you better understand the features of mounting a frame ceiling on vibration suspensions:

For all structures using a false ceiling, the following points are fundamentally important:

• the presence of vibration suspensions;
• lack of rigid connections of the frame and facing sheets with the walls (adjacent to the walls through the Vibrostek-M anti-vibration gasket).

To solve more "modest" acoustic problems, you can use less thick (53, 55 or 83 mm) frameless structures using ZIPS panels (Fig. 4), which, depending on the panels used, provide additional sound insulation in the range from 9 to 14 dB.

In conclusion, it should be noted that when carrying out any soundproofing work, one should be attentive to the problem of indirect noise transmission in the building. Through the "third" walls and partitions, there can be such a strong sound transmission that, ignoring this fact and directing all efforts to additional sound insulation of one floor, you can not get the expected acoustic effect.

It would seem that living in your own wooden house or a cottage made of SIP panels eliminates the impact of noise from neighbors, playgrounds and car parks, to which residents of apartment buildings are so accustomed. However, often the place of urban noise replaces the noise of a highway, a nearby railway track or an industrial enterprise located a couple of kilometers from a cottage village. In addition, extraneous noise is created by hail, rain and gusty winds. The sounds of nature that interfere with normal sleep are especially audible on the top floor, mansard roof and attic.

How to make soundproofing in a wooden house?

It is recommended to carry out work on soundproofing a private house in parallel with the construction of walls and partitions, and the installation of thermal insulation. For a wooden house, only composite materials are suitable that do not contain combustible polymers and other flammable synthetic additives.

Soundproof materials

We have already written about modern materials for soundproofing a house in one of the previous articles. Today, there are about a dozen innovative products on the construction market for maximum noise protection. Building materials that combine sound and heat insulation properties are produced by MaxForte, Korda, SoftBoard, KNAUF, Technikol, Parok and other manufacturers from Russia and Europe. The products are supplied in the form of rolls, strips, mineral plates and flexible mats.

Types of noise

The noise propagated in a room can be classified according to the way the sound waves are transmitted.

• Airborne noise is transmitted through the air and has no physical connection with the building envelope. The simplest soundproofing of a wooden house can easily cope with it (the noise of cars and trains outside the window, the sounds of TV in the living room, the sound of water in the shower).
• Impact noise is created by physical contact between an object and a surface. It spreads along the body of the surface and adjacent building structures (a child running on the top floor of the house, the sound of rain on the roof, lowering heavy sports equipment onto the floor or a frame welded to the floor).
• Structural noise is created when an object enters the structure itself. This type of noise is able to overcome the maximum distances within a residential building (driving nails into the floor with a hammer, drilling holes in the wall with a perforator).

In addition, noise, like any other sound, can be grouped according to the frequency spectrum:

• Low - the elderly hear it well, but children hear it poorly (the hum of long-distance trains, the background of industrial enterprises, the vibration of the phone on the table).
• Medium - most people can hear it well (people talking in the house, watching TV, washing machine operation).
• High - children hear it well, elderly people hear it poorly (squeak when electronics work, play the violin, sharpen knives).

Soundproofing walls, floors and ceilings

Soundproofing the walls in a wooden house is an important but insufficient procedure. Most impact and structure-borne noise is transmitted from one structural element of the house to another, allowing extraneous sounds to seep through floors, ceilings, hidden partitions and panels. Therefore, the issue of sound insulation should be addressed comprehensively, affecting all vertical and horizontal planes of the house.

load-bearing walls

When arranging the soundproofing of the load-bearing walls of a wooden cottage from the inside, it is necessary to give preference to materials of small thickness. These include natural cork and polyethylene foam. By choosing a thick insulator, you will lose the useful area of ​​\u200b\u200bthe house and deliberately reduce the size of the rooms.

For low-budget construction, you can use proven materials such as mineral or stone wool, as well as foam, but you will have to sacrifice footage - these materials are thicker. The golden mean is the installation of drywall. The building sheet has an average thickness and is relatively inexpensive.

Before soundproofing the load-bearing walls inside the house, it is necessary to conduct a thorough inspection of them to identify cracks, chips, backlashes and cracks. Any deficiencies found must be corrected. If you arrange noise absorbers in an already built house, you need to dismantle the sockets, and visit the foam or fiberglass in their holes, thereby creating a local blockade for sound waves. The entrances of any pipelines in the room must be sealed with elastic sealants.

To fix sound insulation, special wooden profile structures or their analogues made of galvanized metal are installed. Such crates are fixed vertically to the floor and ceiling, without fixing them to the walls, otherwise the fasteners can become a conductor for sound. Insulating materials are tightly laid in the area between the profiles. After the installation of sound insulation, slabs of high-quality drywall are installed on top of the crate, the seams and attachment points are puttied. This completes the rough finish of the walls with soundproofing.

Internal partitions

Thin wood, from which the internal partitions of the house are made, is a good conductor of not only warm air, but also sound waves. Therefore, without a quality insulator, the owners of the house will hear even the quietest squeaks of doors and the running of a cat or dog, while being in another part of the house.

To reduce the noise level, it is necessary to sheathe the partitions with drywall on both sides or install a three-layer structure from external sheet materials such as chipboard and fiberboard, as well as an internal soundproof layer. You can make homemade partitions using various noise-absorbing materials, such as volcanic igneous basalt slabs, or use finished products with battens.

Floor

When choosing floor sound insulation, preference should be given to those materials that absorb not only airborne noise, but also protect against impact sounds. To do this, it is necessary to consider the structure of the material - if it is dense, then children's running on the second floor will not be heard by guests on the first floor. In addition, it is important to take into account the possibility underfloor heating installation. Not every sound absorbing material can be heated.

Modern materials are suitable for soundproofing the floor of the house - dense types of mineral and glass wool, polystyrene foam. Separately, it is worth noting expanded polystyrene (EPS) - bulk or tile material, which has proven itself for "floating" floors. The maximum sound insulation effect is achieved due to the weak adhesion of the foamed polystyrene to the structural elements of the house.

Relatively popular for soundproofing the floor in a wooden house is crushed and heat-treated volcanic glass - expanded perlite. Depending on the size of the fraction, its bulk density can be from 40 to 500 kg per cubic meter, which allows you to choose the material for different floors of the building.

Overlappings

Just below the floor of the sleeping floor and the flooring of the attic, “sound bridges” should be avoided. These are small tubules formed by the contact of wooden elements. Their appearance is undesirable, because thanks to the "sound bridges" the waves are easily transmitted through the structural elements of the building from one point of the house to another. Therefore, it is required to place damping materials between floor beams and floor joists. In this case, it is not required to fasten the logs to the beams. Between the lags it is necessary to tightly lay sound-absorbing materials. From above, the logs can be covered with a thin layer of polyethylene foam.

Ceiling

To soundproof the ceiling in a wooden house, special gaskets are used, which are placed between intersecting structural elements. Products absorb vibrations and reduce impact noise. It is necessary to assemble the ceiling in such a way that the installed logs form a lattice. The lattice structure increases rigidity, which, in turn, has a positive effect on the level of sound absorption. Among other things, interfloor structures are covered with sand and expanded clay. Backfilling can only be done on polyethylene film laid over Texound membranes, Isotex panels and other similar materials.

Soundproofing a house from SIP panels

The methods of soundproofing SIP-houses practically do not differ from the methods of noise protection of wooden buildings. Since OSB boards are lightweight, the main task of the cottage owner is to increase the mass and resistance of materials to sound waves. With the help of traditional drywall (GKL and GVL), the RW sound insulation index in a house made of SIP panels can be raised to European standards. A popular and proven material among the owners of SIP-houses are sound-absorbing slabs "Acoustic Butts" from Rockwoll.

The slabs are made from safe stone wool and can be installed to absorb noise in studded partitions, load-bearing walls, false ceilings and joist floors. In addition, to reduce the volume of extraneous noise, it is recommended to use decorative and technical cork coatings.

Do windows and doors need to be soundproofed?

Windows and doors are the most vulnerable places that transmit sound well into houses made of SIP panels. It is necessary to install window and door blocks in the openings of the assembled house kit in accordance with GOST. The problem of street noise penetration is solved by soundproofing door and window openings, as well as by installing multilayer entrance doors and double-glazed windows.

Metal doors with a leaf thickness of 70-90 mm are sold by Guardian, Torex, Termo and other manufacturers. Cork sheet, isolon and extruded polystyrene foam, laid in 3-7 layers between steel sheets, reliably protect the house not only from noise penetration, but also from icing.

When choosing noise-insulating double-glazed windows, you need to pay attention to the type of glass. It is recommended to mount windows made of film or laminated triplex with intermediate layers of PVB (Polyvinyl Butyral) or EVA (Ethyl Vinyl Acetate).

High-quality sound insulation of a private house is to significantly reduce the amount and strength of noise penetrating from the street. This event contributes to the creation of the most convenient, comfortable atmosphere for living in the cottage. It is clear that the soundproofing of each house requires an individual approach, because the choice of materials and the technology for their use directly depends on the characteristics of the structure, the type of surface to be treated and, of course, on the requirements of the owners of the cottage. However, speaking in general, the whole process of soundproofing a private house comes down to creating additional sound protection for various parts of the structure, and below we will talk about this in more detail.

Sound insulation of load-bearing walls in the house

The key feature of load-bearing walls is that they “default” well delay sounds coming from the street, but often this is not enough. For example, if a house is built from ordinary red brick, its ability to stop noise to create a truly cozy and quiet environment inside the building will not be enough. And in order to achieve high-quality sound insulation of load-bearing walls, experts advise resorting to the creation of a multilayer structure. It consists of two layers of brick, between which there is an air gap. This is one of the most effective ways of soundproofing, which is used even at the stage of capital construction.

Between the layers of bricks, an insulator layer is mounted, which not only prevents extraneous sounds from entering the house, but also helps to retain heat in it.

Sound insulation of partitions

The need for soundproofing partitions arises if the walls inside the house are built from beams and mounted on a metal profile. If concrete or brick was used as a building material for the construction of partitions, their additional sound insulation is not needed.

For soundproofing partitions, it is better to use soundproof panels, which today can be bought at every specialized store. Of course, such structures will increase the load on the interior partition, but at the same time they will turn into an insurmountable barrier to noise and become a reliable barrier to acoustic waves.

Soundproofing floors in a private house

If the cottage consists of several floors, professionals advise to additionally isolate the floors. This event is in many ways similar to the sound insulation of load-bearing walls. An excellent solution to the problems of excess noise is a high-quality floor screed on the upper floor and the construction of a false ceiling (multi-layer structure) on the lower one.

Soundproofing doors and windows

The quality of double-glazed windows and the correct installation of them have a direct impact on the soundproofing characteristics of doors and windows. However, in order to achieve the maximum effect, additional processing of door and window openings will not interfere. For this, classic sound insulators are often used - any fibrous material that absorbs sound waves well. It is necessary to perform sound insulation of windows and doors at the stage of installation of these parts of the structure, because after the installation is completed it will be impossible to do this.

Materials for soundproofing houses

A wide range of materials used for high-quality sound insulation of private houses is presented on the modern market. The choice of one or another of them, as mentioned above, depends on many factors, in particular, on the characteristic features of each insulator.

Soundproof materials fall into two categories:
