The best car soundproofing is a set of measures. Modern materials for soundproofing walls in an apartment: all the secrets Efficient soundproofing of walls in an apartment roll thin

18.11.2019

Silence is one of the main components of a good and comfortable rest, which can be achieved in modern technological world not so easy. Extraneous sound people can perceive even during sleep, so most residents apartment buildings, want to protect their peace good and reliable sound insulation. The modern construction market is able to solve this problem, abundance a wide range sound-absorbing and noise-insulating materials. This article will tell you which ones are better, the most popular and of high quality, and what is their difference.

Types of noise in the room

Depending on the nature of the origin of the noise, the material is selected to eliminate it. And it comes in several forms:

Air- enters housing through the air and is a sound wave emanating from various types of transport, loud conversations, TV, speakers and other similar sources. These are noises that are familiar to everyone and sometimes very annoying. Penetrate into rooms through window and door openings, ventilation holes, thin exterior and interior walls.
Shock. Noise activity of this nature is a wave of sound that is transmitted through pulses in solid materials. The most common example is the work of a perforator in a neighboring apartment or a jackhammer on the street, stomping, jumping, etc. Noise from it propagates through load-bearing structures and other rigid building elements. More common for industrial premises and accompanies construction work.
Structural- this is a combined type of sound effect, which includes shock and air vibrations.

For each type of noise, their own methods and methods of soundproofing are selected using certain materials.

Important! At high levels of extraneous sounds, multilayer soundproofing materials are used.

Peculiarities

Noise insulation can be different in structure, thickness and purpose. There are two main types - thick and thin. The first has a soft base and a sound absorption coefficient ranging from 0.8 to 0.95 units, and the second has a weaker noise absorption index, which usually does not exceed 0.5. For example, the value of such a coefficient for expanded polystyrene and polystyrene is 0.15-0.20 units and, according to the classification, corresponds to the E-class. To ensure perfect protection, it is recommended to use materials of a class category of at least C.

To date, there are several best practices reduce sound load per room:

Finish the entire surface of the walls with fibers that absorb sound waves. They are usually produced as porous mats and mounted in frame structures.
Glue dense, but thin (up to 20 mm) and rigid roll materials that reflect sound effects from outside well. This method is also called frameless. Sometimes the raw materials for it are supplied in the form of honeycombs.

Naturally, the method that combines both of the above methods will be the most effective.

Important! Before starting measures to eliminate sound stimuli, it is recommended to determine their nature and sources of origin as accurately as possible. This will make it possible to avoid unnecessary expenses and better solve the upcoming problem. For example, if the outer walls do a good job of soundproofing, and only the activity of the neighbors behind the partition interferes with calmness, then it is most reasonable to isolate the adjacent internal partitions.

Classification

According to the performance and purpose, sound insulation is divided into several subspecies:

Sound absorbing. Such raw materials are capable of converting sound energy into thermal energy and thereby reducing the intensity of the impact of the wave. These include fiberglass and basalt slabs. The installation of such products involves the construction of a frame, followed by cladding with plasterboard.
Soundproof. The principle of operation of such a line of building materials is that they block the path of a sound wave, preventing the latter from penetrating into the room. These include GVL and GKL, soft fiberboard and other materials are also used.

Advantages and disadvantages

Choosing suitable material and determining the future technology of work, you need to clearly understand and understand the pros and cons of certain options.

Frame technology

Includes work on the installation of a supporting structure made of a metal profile or wooden bars and covering them with plasterboard sheets. The inner void, between the latter and the wall, is laid with a thick layer of mineral wool, cellulose-based insulation or ecowool. The advantage of such building materials is an excellent noise-absorbing function and the creation of an additional layer of thermal insulation of external and internal walls. The disadvantages, as a rule, include the difficulty of installation and an increased amount of debris and dust during its implementation, a decrease in the area of \u200b\u200brooms, since the insulation pie reaches up to 10 cm and above. Also, to perform work on this method, you will need more time and money. The most famous trade marks mineral roll insulation are Knauf, Isover and others.

Also for such events, "sandwich panels" are used, which are fiberglass mats enclosed between drywall sheets. The material has good noise-absorbing properties, easy to install, as it can be attached both to the frame and to the adhesive solution. The disadvantage is a significant thickness, which can be a critical moment for small areas.

Important! The use of two-layer drywall or gypsum fiber panels greatly increases noise suppression.

Frameless technology

This method is based on the principle of mounting sound-absorbing materials, without the construction of frame structures. We can distinguish a number of the following insulators:

Decorative panels is an innovative natural product made from wood fibers conifers. It is produced in the form of standard rectangular panels, the connecting elements of which are spikes and grooves. Installation of such a coating is very simple and convenient and can be done by hand in the shortest possible time. The surface of the finish has a decorative top layer, which eliminates the need for additional cosmetic processing of the latter. This material is impossible better fit for large areas, and only a significant cost can be called its disadvantage.

Polyurethane boards are excellent material, which, due to its absorbent properties, is even used in movie theaters and recording studios. Products are made in standard rectangles 120 by 60 cm with a layer thickness of not more than 1.5 cm. The advantage of polyurethane is ease of installation, lightness and excellent performance, and the disadvantage is its high price.

Cork coating is very interesting and beautiful. finishing material capable of absorbing extraneous sounds. Attaches by simple sticking to the wall. It has excellent qualities, but is significantly inferior to other similar materials, as it is rather thin.

Soundproofing membranes are cutting-edge raw materials with a thickness of only 3.5 cm, which allows it to be used in combination with other types of sound insulation. Installation is also quite quick and easy, as the membrane is bent and can be attached at any angle. With all this, it also has a high density, which creates an ideal protection against external irritants. The downside is the high cost.

Liquid soundproofing is know-how in the world of building materials. This exotic method has not yet gained popularity among our citizens, but it has great prospects in the future. Its undeniable advantage is excellent performance and minimal use of free space, due to the thin layer.

The thickness of the products is 1.3 cm, and the weight, depending on the size, is 10.5 and 18.5 kg, respectively. The products are mounted using a simple drywall adhesive.

Results

The method of fixing sound insulation directly depends on what type of materials you choose. There are two main types of installation - frame and frameless, each of them has its own advantages and disadvantages, which were described above. In order to do the finishing work yourself and qualitatively, and the selected coating reliably protected you and your family from unwanted noise exposure, study the instructions attached by the manufacturer or seek advice from professional acousticians.

As the quality of housing improves, when the issue of the number of square meters has ceased to be the only determining factor, the problem of soundproofing residential premises is becoming increasingly relevant. However, due to the fact that this question is quite specific, i.e. in the theory of acoustics there are a lot of implicit features and "illogical" conclusions from the point of view of common sense, a large number of myths and misconceptions have arisen and established themselves in this area.

This leads to the fact that a large number of people have formed a stable stereotype about what materials, if necessary, can solve all the problems of insufficient sound insulation. However practical use such materials, at best, will leave the situation without visible changes, at worst, it will lead to an increase in noise in the room. As a first example:

The myth of the soundproofing properties of cork

Almost everyone believes that cork is a good sound insulator. Statements of this kind can be found on many building forums. And the "technology" of application is "developed" to the smallest detail. If you hear a neighbor behind the wall, you need to paste a cork over the wall that is common with your neighbor, if the noise comes from the ceiling, then the ceiling. And the resulting acoustic effect is amazing ... with its absence! But what's the matter? After all, the seller showed acoustic test data, where the effect of sound insulation was indicated, and not a very small effect - about 20 dB! Is it cheating?!

Not really. The numbers are true. But the fact is that such figures were obtained not for "sound insulation in general", but only for the so-called impact sound insulation. In addition, the indicated values are valid only for the case when this cork coating is laid under a concrete screed or parquet board from a neighbor from above. Then you really hear the neighbor's steps quieter by 20 dB compared to how if the neighbor did not have this pad under his feet. But for music or the sound of the neighbor's voice, as well as for all other cases of using cork in other cases, these figures of "sound insulation" have, unfortunately, nothing to do. The effect is not just barely noticeable, it is zero! Of course, cork is an environmentally friendly and warm material, but you should not attribute all possible soundproof properties to it.

All of the above also applies to foam, polyethylene foam (PPE), polyurethane foam and other similar materials that have different trademarks starting with "foam-" and ending with "-fol", "-fom" and "-lon". Even with an increase in the thickness of these materials up to 50 mm, their soundproofing properties (with the exception of impact noise insulation) leave much to be desired.

Another misconception closely related to the first. Let's denote it as:

The myth of thin soundproofing

The basis for the emergence of this misconception is the struggle to improve the acoustic comfort of the room, along with the desire to preserve the original square meters. The desire to maintain the height of the ceiling and the area of the room is quite understandable, moreover, for standard apartments with a small footage and a low ceiling. According to statistical observations, the vast majority of people are ready to donate "for sound insulation" an increase in the thickness of the wall and ceiling no more than 10 - 20 mm. In addition, there is a requirement to obtain a rigid front surface ready for painting or wallpapering.

Here, all the same materials come to the rescue: cork, PPE, polyurethane foam up to 10 mm thick. Thermal soundproofing is added to them in a separate line. But for this case, these materials are sewn up with a layer of drywall, which acts as a rigid wall, ready for finishing.

Since the acoustic properties of cork and PPE for soundproofing walls and ceilings were discussed above, we will focus on thermal soundproofing.

Thermozvukoizol (TZI) is a rolled material, where Lutrasil polymeric material is used as a shell (like a duvet cover), and super-thin fiberglass fibers are used as stuffing (blanket). The thickness of such material fluctuates around 5-8 mm. I do not presume to discuss the thermal insulation qualities of VBI, but as for sound insulation:

First of all, TZI is not soundproofing, but sound-absorbing material. Thus, we cannot talk about his own sound insulation. We can only talk about the sound insulation of the structure in which it is used as a filler.

Secondly, the sound insulation of such a design largely depends on the thickness of the sound-absorbing material located inside. The thickness of the VBI, at which this material will be effective in a soundproof structure, should be at least 40 - 50 mm. And this is 5 - 7 layers. With a layer thickness of 8 mm, the acoustic effect of this material is VERY SMALL. As, however, in any other materials the same thickness. Nothing can be done - the law of acoustics!

As really effective material ZIPS panels can be recommended for additional soundproofing of walls and ceilings. For example, ZIPS-Vector panels with a structure thickness of 53 mm increase sound insulation by 9-11 dB, and the latest ZIPS-III-Ultra with the same thickness - by 11-13 dB. The panels are patented and currently have no analogues in the world.

Thus, with a total thickness of the structure of additional sound insulation of 20 - 30 mm (including a layer of drywall), one should not expect any increase in sound insulation that is noticeable to the ear.

In addition to these, perhaps the most common misconceptions, there are others, less known, but no less significant. Therefore, in matters of ensuring the required sound insulation of premises, it is best to immediately contact specialists. Sometimes a single glance is enough for a professional acoustician to immediately assess the ineffectiveness of the proposed measures or the materials used. But the most unpleasant thing is to spend time, effort and money, and not feel the results of your work.

Comprehensive soundproofing of walls, ceiling and floor will help to avoid the entry of extraneous noise into your apartment. But doing a complete soundproofing of an apartment is very expensive and not always advisable, especially in cases where a specific apartment is the source of annoying noise. If you are tired of neighbors on the floor, you can get rid of the noise in their apartment with the help of soundproofing adjacent walls. In this article, we will figure out how to soundproof walls.

With the construction of new houses, there is an increasing tendency to reduce the weight of the structure. This reduces the cost of the foundation, which negatively affects the soundproofing of the room. Not everyone is interested in hearing what his neighbors are doing. That is why the soundproofing of an apartment is a concern not only for those who live in old panel houses but also in new buildings.

Due to the large assortment of soundproofing materials on the market, you can get confused. The choice should be approached responsibly, because each material has its own purpose. Increasingly, people are interested not only in how well the material will fight sound, but also whether it is safe to use it in a residential area. Not everyone wants to breathe phenol vapors and install glass wool.

In this article, we will consider materials for soundproofing the walls of a Russian manufacturer MaxForte.

Which can be used for frame and frameless circuits.

MaxForte EcoSlab

MaxForteSound Pro and MaxForte EcoSlab

For enhanced sound insulation, a combination of materials is recommended, for example - MaxForteSound Pro and MaxForte EcoSlab. Using such a scheme will allow you to get the highest possible sound absorption, including low frequencies (stereo systems, home theaters)

But it is not always possible to "eat" precious centimeters from the wall and you need to do it as subtly and efficiently as possible. In this case, frameless soundproofing will be a proven option.

How to carry out the installation of sound insulation without making a frame with MaxForteSound Pro:

Everyone chooses the best way for themselves based on the calculation of forces, personal preferences and financial capabilities.

If you make soundproofing according to our recommendations, you can safely count on good comfort and silence.

Sound insulation of walls is carried out using the following materials:

- Self-adhesive soundproof membranes.

- Combined panels with a layer of sound-absorbing materials.

- Plates made of synthetic and mineral materials.

- Mineral wool.

Cork panels.

In addition to the basic materials, depending on the method of soundproofing you choose, you will need:

metal profile or wooden bars, for frame guides.
Drywall, chipboard, or other decorative wall covering.
Doubel screws.
Mountings for plates.
Screws.

Each soundproofing manufacturer has its own installation technology, so you may need additional expendable materials not included in the list.

Soundproofing installation

Preparatory work

Before proceeding with the installation of sound insulation, it is necessary to carry out a number of preparatory work:

Remove the old wall covering (wallpaper, decorative panels).
Remove sockets and switches. If there is a wiring junction box on the wall, remove the cover from it. Don't forget to de-energize the wiring first.
Remove the wires from the box and sockets for the switch and sockets.
Extend the wires for the switch and sockets to the length of the future insulation.
Temporarily insulate the bare ends of the wires.
Fill up the nests and the box cement mortar or mounting foam.
Inspect the wall and joints between the plates for cracks.
Seal cracks with cement mortar.

If you are poorly versed in electricity, then for work related to wiring, invite a professional electrician.

Frame manufacturing

The best way to block sound is the frame method of soundproofing, which is why we will consider it in our article:

Stick on the entire area of the wall, a thin soundproof membrane. You can use a self-adhesive membrane or use special glue to fix it.
Make a frame frame, for this, install vertical guides along the edges of the wall, as well as horizontal ones, under the ceiling and on the floor. Use dowel screws to secure the guides.
Install the vertical guides inside the frame, at a distance of 40-50 centimeters from each other.
Place sound deadening material between the frame rails. To fix the sound insulation in the frame, you can use glue or bendable metal tape attached to the guide screws.
Inspect the frame for voids and gaps. There should be no gaps and empty space in the frame.
Lead the wires of the switch, sockets and wiring through the insulation.
Install drywall sheets or other finishing boards on the frame. When installing the panels, make holes for the junction box, switch and sockets.
Seal the seams between the panels.
Install the finishing wall covering (wallpaper, plaster).
Install sockets, switch and junction box.

Methods of soundproofing without a frame

In order to save space, many people prefer to use a frameless soundproofing method. This method really allows you to reduce the thickness of sound insulation by 2-3 centimeters, but at the same time, the quality of noise insulation is significantly reduced.

For soundproofing without a frame, combined panels are mainly used, which are glued directly to the wall. After that, the panels are plastered or covered with wallpaper. In addition to gluing, panels and soundproofing plates can be installed on the wall using special fasteners located at the corners.

In addition to rigid plates and panels, it is possible to produce sound insulation without a frame using soft roll material, for example, a self-adhesive membrane. The membrane is glued to the wall and covered with finishing panels. True, the quality of sound insulation with this method leaves much to be desired.

Too loud sounds disturb the peace. They do not allow you to concentrate on successfully solving complex problems, become causes of discontent and. Their presence interrupts the rest, prevents effective recuperation. Such interference has a negative impact on the psyche and can even provoke diseases. To eliminate the listed troubles, specialized soundproofing of the walls in the apartment will help. Modern materials and methods of their application are discussed in this article.

It is necessary to determine the parameters of negative impacts that need to be eliminated completely, or to reduce their intensity to an acceptable level.

Sound vibrations are distinguished by their ability to propagate. Low frequencies are especially difficult to mute. They create vibrational vibrations, penetrate through thick walls and other elements of building structures. Medium and high frequencies are easier to hold. For this, materials with a special surface relief are used. The waves that fall into such traps are redirected in a special way to mutually reduce the amplitude of the oscillations.

Such a decision will only slightly muffle the clatter of neighbors from above. Foamed polyurethane foam has a chaotic internal structure. It has voids that provide . However, such a technology for reducing the amplitude of sound vibrations will not work effectively. It should be noted another design flaw in the figure above. Here the metal crate is attached with dowels to interfloor overlap. Through these elements, noise will enter the room.

Texound is heavier, stronger and more expensive than the options listed. This material provides good protection from noise at a small thickness. It is used to save the interior space of rooms. If necessary, an additional layer is installed to improve the thermal insulation parameters of the structure.

Soundproofing the walls in an apartment can be done cheaply with your own hands, if you take into account all the above facts and the architectural features of the premises.

Soundproofing methods

Sound insulation of walls, ceiling and floor is carried out in three ways:

- Frame - this method involves the installation of rails on the wall for the installation of cladding panels. Between the guides, sound-absorbing material is placed, after that, sound-reflecting panels are installed. In some cases, such as in recording studios, panels have a non-reflective surface, but an absorbent surface.
  The advantage of this method is the high quality of sound insulation, and the disadvantages are the high cost of work and the reduction in the usable space of the room.

- Installation of plates and membranes- in this method, the soundproofing material is installed or glued directly to the wall, floor or ceiling. After that, the plates and membranes are plastered or covered with thin panels.
  With proper observance of the technology for installing plates or membranes, the quality of sound insulation is not inferior to the frame method, and the financial costs are significantly less.

“Floating” - this method is used only for soundproofing the floor. The insulating material is spread on the floor and covered with a waterproofing layer. A reinforced screed is made on top and a floor covering is installed. The advantage of this method is the absence of rigid fasteners, which contributes to a significant reduction in vibration noise.

Soundproofing materials

Soundproof materials are of the following types:

soft insulation

Soft sound insulation materials include different kind fibers sold in rolls:

- Soundproof membranes- there are self-adhesive and ordinary, made from synthetic and natural fibers. Used for walls, ceilings and floors. Separately, for floor insulation, membranes are produced from bituminous polymers with a layer of polyester felt.

- Needle Punched Fiberglass Material- Used for walls and ceilings. Good insulation for frame structures.

- Polyester backing- made specifically for the "floating" floor, great as a substrate under the laminate.

Mineral wool- a simple and affordable heat and sound insulating material used in wireframe method isolation.

MaxForte SoundPro

New generation material based on theoretical developments in the field of building acoustics and practical experience installation work. With a minimum thickness of 12 mm, the material provides maximum protection against airborne and impact sound and is indispensable in small apartments, where every centimeter counts! Completely environmentally safe: does not contain adhesives and other chemicals. MaxForte-SoundPRO is ideal for any premises: apartments, kindergartens, schools. Also, the material acts as a fire protection (completely non-combustible) and thermal insulation!

MaxForte EcoSlab 60

Material MaxForte-ECOplate is made of 100% volcanic rock (without impurities, slag and blast-furnace waste). MaxForte-ECOplate has excellent acoustic properties, which allows this product to be successfully used for soundproofing the most acoustically difficult objects: multiplex cinemas, recording studios, listening rooms, home theaters, etc.

MaxForte EcoAcoustic

It is made from 100% polyester (polyester fibers) without the addition of adhesives. For shaping, an innovative thermal bonding technology is used (melting the polyester fibers themselves). The material is produced on modern SIMA equipment (Italy), only primary raw materials are used in the production. EcoAcoustic is completely safe for human health: the plates do not emit and do not contain harmful substances!

Sealant MaxForte

Sealant MaxForte is intended for sealing seams, joints, holes in the soundproofing of walls and ceilings, as well as in the construction of "floating" floors and floors on logs. Due to the low modulus of elasticity, the sealant has excellent vibroacoustic properties and provides a significant reduction in vibration load between building structures acting as a damping layer.

VibroStop Pro

Vibration-isolating mount designed to combat impact noise penetrating through floor slabs and walls. The use of VibroStop PRO allows you to significantly reduce the vibration load on the profile and provide additional sound insulation of the ceiling and walls at a level of 21 dB.

MaxForte Shumoizol

The rolls are spread with the soft side on the floor, the edges lead to the walls. After work, any excess can be easily cut off. The joints between the rolls are smeared liquid rubber MaxForte Hydrostop.

Advantages:

Impact noise reduction 27 dB.
The material does not tear and does not crack during laying, due to the addition of imported plasticizers to the composition.
It can be used as waterproofing, the material is waterproof.
The material can be used for dry screed and under the laminate.

MaxForte SoundPro

Installation is carried out by analogy with Shumoizol, the edges lead to the walls, the rolls themselves are overlapped by 5 cm, and the joints between them are coated with MaxForte Hydrostop liquid rubber. Next, a building film is laid, this is done so that the screed solution does not penetrate the sound insulation layer.

Advantages:

Impact noise reduction 34 dB.
Level reduction airborne noise 10 dB.
Rolls are resistant to moisture. Not subject to decay.
It belongs to the sound absorption class "A" out of five possible.
The material does not attract rodents.

MaxForte EcoSlab 110 kg/m 3

To begin with, the MaxForte tape is laid around the perimeter in two layers. The plates are placed on the floor close to each other and covered with construction film.

Advantages:

It belongs to the sound absorption class "A" out of five possible.
Completely non-combustible material.
Does not contain phenol resins.
Due to the optimally selected density of 110 kg / m3, the screed does not spring and does not burst over time.
Sound insulation at the level of 36-38 dB.

If it turned out that the apartment already has a screed, or it is an old housing stock, where the ceiling simply cannot withstand the heavy weight of the screed, an effective option is the floor on the logs.

solid insulation

The type of solid sound insulation includes simple slabs and combined panels made of sound-absorbing materials:

- Combined panels- represent a design of two sheets and an interlayer. Sheets are made from chipboard, cork or synthetic materials. Quartz sand and mineral wool are often used as an interlayer.

- Basalt slabs- made from basalt fiber. Additionally, the boards can be treated with a water-repellent compound.

- Polyester fiber boards- synthetic sound insulation, easily cut to the desired size, widely used in frame construction.

- Staple woven fiberglass boards- designed to fill the inter-profile space, insulate suspended ceilings and frames installed on the walls.

- Cork slabs are made from cork fiber. Wall panels and cork laminate can be installed without additional soundproofing materials.

foam boards- cheapest and widest known material for soundproofing. Foam boards are inferior in sound insulation quality to more modern materials, but thanks to affordable price, remain a popular option for budget repairs.

Handy soundproofing

Few people know that some interior items can serve as good sound absorbers and reduce noise levels by 20-30 percent:

- A large carpet - laid on the floor or hung on the wall - can significantly reduce the level of incoming or outgoing noise.

- furniture wall- installed along a common wall with neighbors, will save you from loud noise, turning it into a soft hum.

Thick material curtains- able to muffle the sounds coming from the street.

Soundproofing walls, ceilings and floors

Soundproofing technologies for floors, walls and ceilings are different from each other, therefore, we will consider each process separately.

Floor soundproofing

Floor soundproofing is done to block noise coming from the apartment located on the floor below, or vice versa, so that the noise produced in your apartment does not annoy the neighbors downstairs. To isolate the floor, you can use the "floating" floor method, or make a frame from a log.

In the first option, you need to spread soundproofing material over the entire surface of the floor, then make concrete screed. After that, a laminate, or other type of flooring, is laid on the screed. In the frame method, it is necessary to make a crate of wooden bars (lag). Insulating material is laid between the lags, the field of this crate is closed with chipboard or boards. To reduce vibration noise, it is recommended to place special vibration-damping pads under the logs.
Detailed article.

Wall soundproofing

You can block the sounds coming from the apartments of your neighbors on the floor by soundproofing the walls adjacent to them. Please note that it makes no sense to isolate all the walls in the apartment, including internal partitions.
For wall insulation, you can use self-adhesive soundproofing membranes, combined panels or boards installed in a special frame. Keep in mind that the thicker the sound insulation layer is, the less usable area of your apartment will remain.
Another important factor in the soundproofing of walls are through sockets, in order to block the sounds coming through them, it is necessary to fill the empty space between your and the neighbor's socket. soundproof material, such as mounting foam.
Detailed .

Ceiling soundproofing

For soundproofing the ceiling, it is better to choose lightweight materials that will not peel off due to their own weight or heavily load the ceiling frame.
If you have already installed suspended ceiling, then you just need to remove the panels and install the insulation on the main ceiling, then install the panels in place.

Remember the "golden" rule - soundproofing is much easier and cheaper to do before finishing work than after the repair is completed!
