Sound insulation panels for walls

Creating a comfortable living conditions - one of the main problems faced by owners of apartments and houses.Of course, when it comes to this, but can not help coming to the fore issues of energy, insulation and heating, water and sanitation, hygienic and beautiful decoration and so on.And very often the concept of insulation itself simply overlooked.And it is in vain - in fact create a truly comfortable accommodation is impossible, if not provided reliable protection against external noise.

Especially sharply this problem stands in front of the residents of apartments in high-rise developments.Alas, we must acknowledge that in the mass of urban construction period the emphasis was on the scale, on the shortest possible time the construction of houses, and questions soundproofing obviously did not stand a priority neither designers nor the builders, and the years of waiting for their turn in the apartment citizens are welcome anyhousing "with facilities".But what level

of sound insulation in high-rise buildings - you know, probably all.However, this issue is relevant for residents of private homes, especially if held near a busy road or railway line, or the neighbors - not to the extent of "alert" dog barking day and night.

What is the solution?Take the initiative in their own hands and ensure yourself a comfortable accommodation on their own.The modern range of construction materials Shops offers a lot to deal with the penetration of outside noise.In particular, the great demand for sound insulation panels for walls, as the most suitable for self-assembly.These products can seriously vary its structure, manufacturing materials, dimensions, installation technology.Let's try to understand their diversity.

Before proceeding to the consideration of specificmodels of acoustic insulation panels should be at least a little to understand the "physics" of sound propagation in residential buildings.This will help to understand the essence and use of appropriate materials and designs.

So disturbing noise in residential areas can have various causes.

  • First of all, the air noise - that is, one that is passed to conventional air vibrations.Typical examples - loud noises, sounds of passing on the street transport, working appliances, including televisions, audio center, etc., musical instruments and much more.Air vibrations are absorbed or reflected in part by partitions, but are able to find distribution channels through loose abutting building structures, openings, vents, holes in the walls (for example, switches and socket outlets).In addition, sufficient light partitions can be a kind of "transmission link" - air vibrations "swing" them and the wall, acting as a membrane, pass them on.
  • Many worry deliver shock noise.They are caused by mechanical action on the surface of building structures, impact or vibration properties.Fluctuations spread over floors and partitions over long distances, and do constructions acoustic noise emitters.
Impact noise is distributed over long distances , and to deal with it - the hardest

Impact noise is distributed over long distances, and to deal with it - the hardest

For such cases include the sounds of falling objects, repairs (classic examples - a hammer or a hammer), the heavy tread of neighbors above or jumping rambunctiouschildren.Sometimes the source of the noise and become household appliances.For example, the vibration exposure may produce unstable installed a washing machine or even standing on the floor subwoofer transmits overlap pronounced low-frequency oscillations.

With impact noise to fight the hardest.Sometimes it is not easy to determine the source, since the vibrations are transmitted in all directions through the building construction on several floors.

  • In addition, very often there are the so-called structural noise.It sounds or vibrations from the operating ventilation systems, power systems, placed in the building, elevators, etc.Structural noise can also be air or impact origin.
  • Separately, you can notice more and acoustic noise.They are due not to external and internal sound source.A classic example - the reflected echoes in the spacious room.With such noise has to fight not so much - they are usually invisible, if the room is finished, making furniture, and this issue is more important for sound recording, television or radio broadcasting studios and other similar premises.Yet sometimes it is necessary to resort to measures to address them in the apartment.For example, the owners are willing to take some space for the "home theater" and thus seek the most accurate transmission of sound without any distortion was reflected.

What does this mean?In order to gain clarity - universal materials capable of coping with all kind of noise does not exist.Thus, the intensity of sound waves of air can be greatly reduced by installing on their way porous or fibrous structures - the energy will be spent on vibrations of the material particles.But rigid partition in this matter is unlikely to become an assistant - is not excluded even the resonance effect, even when such a barrier will increase the noise effect.For impact sound, on the contrary, it is necessary to create a massive barrier, the manufacture of materials that will prevent the transmission of vibrations.

Some homeowners inexperience believe that any suitable insulation for soundproofing.However, practice shows that it is - far from it.Some insulation materials, on the contrary, will contribute to sound rezonatsii, creating exactly the opposite to the desired result.

2016-02-06_134245 Should I consider "Penoplex" as a sound-proof material?

You can tell right away that this is - a very controversial issue, and reasoned arguments to refuse such a lot of noise isolation.All this - in a special publication of our portal devoted to assessing the possibility of acoustic ceiling "Penoplex» .

acoustics experts say categorically - it is impossible to talk about the effectiveness of the use as sound insulation of a material.The desired effect can be obtained only by using sound insulating structures that combine several principles suppression (absorption) drum and air noise.

For example, to reduce the level of airborne noise optimal looks such a structure, made on a "massive - absorption - massiveness»:

Принцип "работы" многослойной звукоизоляционной конструкции

principle of "work" of the multi-layer soundproof construction

From the source of the noise the first "hit" assumesseptum of dense bulk material (pos. 1).Part of the sound waves will be reflected from it.In addition, the dense material is not so easy to get to fluctuate - it also consumes a significant portion of energy.

Further waves pass through a rather soft, porous or fibrous material - for example, mineral wool, foam rubber or a special wood composite.The wave energy is dissipated, wasted on the fluctuations of the loose structure, without significant transmission further.

considerably weakened the previous two layers of sound waves no longer afford to "shake" the third barrier (Pos. 3), a rigid partition and the total transmission of airborne noise is reduced to a minimum or even to zero.

To prevent the spread of impact sound approach already requires a different, for example, the use of high density materials, together with viscosity, which will be able to suppress vibrations of building structures.An example of such a material - sheets or webs "teksaunda".Despite the small thickness due to the increased density and structural elasticity of the material based on mineral effectively dampens sound and vibration fluctuations.

These and other principles taken as a basis for developers of special sound insulation panels for walls and ceilings.Their efforts are aimed at creating an effective noise barriers in combination with the maximum possible completeness of design and simplicity of its installation.

Some popular types of acoustic insulation panels for walls

panels of mineral wool

Perhaps it is worth making a reservation - this kind of material is not in itself acts as a complete structure, and is used to create sound-proofpartitions, along with other components and parts.However, mention should be made about them.

By and large, almost all fibrous insulation materials are able to absorb the sound waves.Still, manufacturers offer insulation in the assortment range of special types designed precisely for such applications.

Species sale occurs a lot.So, enjoy "Shumostop" popular boards on the basis of basalt and glass fibers.Belgorod company "IZOVOL" offers a specialized range of products "Izovol - Protection against noise".And for the more familiar you can see the panel well-known company "ROCKWOOL" with distinctive title "Acoustic Butts".

This slab of basalt fiber (rock wool), ie the material is natural, environmentally friendly.Special processing panels gives them hydrophobic properties - the material does not absorb moisture.The special advantage - a class of "NG", that is the sound insulator does not burn and does not contribute to the spread of fire.Material biostoek - that is, it does not decompose over time and does not serve as a breeding ground for mold colonies or rodent nests.

Proper use of panels "Acoustic Butts" in the system can significantly reduce the level of airborne noise - sound insulation index (Rw) all established construction reaches 63 dB.And this, incidentally, is comparable to the noise from the busy highway.

Material Density - 45 kg / m³, that is easy to work with him.The panels are easily cut, and at the same time perfectly hold them imparted shape during the production process, not showing a tendency to shrinkage.

As befits all mineral-materials, in addition to the sound insulation "Acoustic Butts" plates are distinguished and fine thermal insulation properties.Thus, the coefficient of thermal conductivity, depending on the operating conditions, ranging from 0.035 to 0.040 W / m × ° C.

boards are easy to installation size - 1000 × 600 × 50 mm.Typical

their application for sound insulation - the construction of interior partitions or the creation of additional noise barriers on the ready-made walls.

Variants of using a sound-proof fibrous materials in the wall structure

And in fact, and in another case frame construction is used, which is assembled from metal profiles or wooden beams.After laying the panels "Acoustic Batts' surface is coated in one or more layers of gypsum board or other sheet material (plywood, OSB, MDF, etc.) which have to be invoked to perform finishing.

To improve the sound insulation qualities of the created structure, it is desirable to use an integrated approach.As already mentioned, the fibrous material to help fight the spread of airborne noise, but ineffective against shock.One of the options "multi-purpose" sound insulation shown in the figure below:

One example is the integrated use of mineral wool, "teksaunda" and drywall framing system insulation

on the wall (. Item 1), which requires the creation of acoustic system design, goingframe made of galvanized steel profiles (pos. 2) or bars.To reduce vibration transmission from the floors to the frame, under the guide strips are stacked dense sound-proofing material (Pos. 3), such as "teksaund", or at least a thick felt.The space between the rails tightly filled with basalt slabs "Acoustic Butts" (Pos. 4) or other, like.

external cladding is gypsum board (item 6.), But in this case for him across the back surface of the bonded layer of the same "tesaunda" - it will significantly reduce the spread of impact noise.

Suspensions with anti-vibration inserts

Pendants with anti-vibration inserts

When mounting frame basis under the sound insulation structure is recommended to use not ordinary and special fasteners (suspensions) equipped with antivibration damper insert.This will give even greater efficiency throughout the system created.Incidentally, this also applies to all other sound-absorbing materials, which includes installation of a preset frame structure.

multilayer structure discussed above - quite effectively, but it "eats" a lot of useful floor space.If you approach from this point of view, it is advantageous to use «PhoneStar» sound-proof panel.

This - a proprietary development of the German company «Wolf Bavaria», which the designers were able to implement several principles of noise reduction in panel thickness of only 12 mm.

The panel - a multi-layered structure (triplex).Its frame itself is made of a composite based on natural cellulose fibers.The layers are separated flat space that provide undulating jumper type of corrugated cardboard.All panels are filled voids within the mineral granulate based on purified quartz sand.

This design allows for the use of noise suppression, several important conditions.

  • Firstly, it is multi-layered, which alternating different materials density.In addition, a complex form of internal jumpers repeatedly reflects sound waves in different directions, which helps them to dissipate.
  • Secondly, the particulate mineral structure is excellent absorber of sound waves.The wave energy is dissipated shear quartz grains, with the transition into heat.
  • Third, pulp plasticity prevents the transmission of vibrations, which is very important to combat the spread of impact noise.
  • And fourth - already mentioned above required massiveness - again at the expense of mineral filling.
