What is the best soundproofing? Overview of the best soundproofing materials for apartment walls

Protecting the premises from external noise is an urgent problem for residents of apartment buildings. To solve it, the modern construction market offers a wide range of soundproofing and sound-absorbing materials. Thin soundproofing is one of the effective means of protection. It allows you to reliably protect the home from extraneous sounds.

Peculiarities

In contrast to thick soundproofing materials with a soft structure and a sound absorption coefficient of up to 0.95 units, thin materials stand out with a lower value. Its value usually does not exceed 0.5 units. The coefficient of foam and polystyrene foam is 0.25 units and corresponds to class E. To ensure good protection, it is necessary to use materials not lower than class C.

With a high level of extraneous noise, thin soundproofing materials should be used as part of multilayer structures. In the case of moderate noise and the impracticality of installing a thick panel, it is quite acceptable to use such materials. Noises are divided into three types. They are:

• structural;
• percussion;
• air.

The use of thin soundproofing materials can only protect the room from airborne noise. These include:

• barking dogs;
• operation of the vacuum cleaner and TV;
• crying baby;
• talking and singing.

The indicator of the degree of protection of the material against airborne sound is called the sound insulation index and is denoted by the symbol Rw. The higher the numerical value of Rw, the higher the insulating properties of a particular material. Impact and structural noises have a different nature of origin and wavelength. Therefore, it will not be possible to cope with them with the help of thin sound insulation.

Advantages and disadvantages

The popularity of the use of thin sound insulation is due to a number of positive properties:

• Significant savings in room space due to the small thickness of the material. After its installation, the area of ​​\u200b\u200bthe room practically does not change.
• Easy installation is due to the absence of the need to install a metal frame, laying thick slabs and subsequent sheathing of the structure with plasterboard sheets.

• A wide range of materials with different values ​​of the sound insulation index makes it easy to choose the right type.
• The environmental safety of soundproofing materials is achieved due to the absence of toxic substances in their composition.
• A significant reduction in the time of work in comparison with the time required for the installation of other types of insulation.

The disadvantages include the high cost of some models and the low efficiency of thin materials. Many of them should only be used in conjunction with other types of sound insulation.

Classification

According to their operational characteristics and purpose, thin materials are divided into two classes.

sound-absorbing

They convert sound energy into heat and significantly reduce the intensity of the reflected wave. These are fiberglass and basalt slabs, which can be attributed to thin types of sound insulation only conditionally. Despite the fact that the minimum thickness of the sheets is 3 cm, their installation requires the installation of a frame with further cladding with plasterboard sheets. As a result, the thickness of the structure exceeds the values ​​that fall under the definition of thin sound insulation.

Polyurethane foam panels, which are called acoustic foam rubber, do not require the installation of a frame. They are mounted on the base with glue. The advantage of using this material is that there is no need to level the wall before applying the sticker. The minimum thickness of such a panel is 3.5 cm, which makes it possible to classify this type of sound insulator as a thin type.

Another popular remedy is liquid soundproofing, which refers to sound-absorbing agents. The material is applied to the wall and covered with a decorative panel or plasterboard. The thickness of the applied layer should be at least 3 cm. The thinnest representative of sound-absorbing materials is a roll cork, its thickness is 0.8 cm. This type of soundproofing material is considered universal.

With it, you can reliably protect the room from extraneous sounds, effectively decorate the space, using the material as a decorative coating. When choosing a cork sheet, it should be borne in mind that the diameter of the crumb should not exceed 3 mm. Models made of 6 mm crumbs are somewhat inferior in soundproofing qualities to fine-grained material. Therefore, you need to choose the material carefully.

Soundproof

These types of soundproofing block the path of the sound wave, preventing sound from entering the room. The most common materials of this type are GKL and GVL. However, they should be mounted at a distance, leaving a gap between the sheathing and the wall for filling with sound-absorbing tiles of at least 3 cm. As a result of a multi-layer structure, the total thickness of the “pie” can be 4 cm. This is a conditionally thin type and cannot be considered as an absolutely thin sound insulation .

Decorative panels are a fairly effective type of sound insulation. Therefore, they are in demand among consumers. The sheets have a layered structure, they are made in the form of a cardboard frame with a mineral filler inside. Quartz sand is more often used as a filling, which obliges to seal the sections of the panels with adhesive tape when cutting them. This is practically the only drawback of this material.

Thin materials include some models of acoustic boards made of soft fiberboard with a thickness of 1 to 3 cm. The panels have a multilayer structure. They consist of a reinforcing mesh, polystyrene foam and waterproofing. This type also includes decorative boards made of wood fiber with a thickness of 1.2 to 2.5 cm.

Ultrathin

On the modern market of building and finishing materials, there are many ultra-thin films and membranes that can intercept the sound wave and neutralize it. The soundproofing characteristics of membranes are directly dependent on the frequency of extraneous sound. They differ from each other by the critical frequency. This is the name of the lowest of the frequencies, after which the soundproofing properties of the material are reduced.

Of the building materials, concrete and brick have the highest critical frequency. Rubber and steel perform well, lead has the best. However, due to its harmfulness to the human body, it is not used in the production of insulating membranes. A polymer-bitumen membrane has a critical frequency comparable to lead. Unlike it, it does not contain harmful impurities, it does not have a negative impact on human health. The material has a polypropylene coating, its total thickness is only 0.4 cm.

Mineral membranes have good performance characteristics. They are one of the thinnest representatives of sound insulation, their thickness is from 0.25 to 0.37 cm. Among them, the most famous are the aragonite variety (“Texound”) and barite mambrana (noise block or loaded vinyl). The composition of the coatings includes polymers that give the films high elasticity and plasticity.

Popular means of soundproofing are a 0.5 cm thick polyethylene coating under the wallpaper and 0.7 cm thick lead foil covered with a polyurethane foam layer. The ultra-thin wallpaper pad is made from polyethylene foam wrapped with thermolaminated sheets. To ensure the best sound insulation performance, it is recommended to use multilayer membranes, alternating them with sound absorbers. From liquid materials it is worth highlighting Green Glue with a viscous structure. It is applied to the reverse side of the GCR boards before they are installed. When solidified, the substance creates a reliable barrier to sound waves and provides good sound insulation of the room.

Kinds

Among the most popular and frequently used materials are several varieties.

Isoplaat

This is a natural, environmentally friendly soundproofing board, which includes coniferous wood fibers. The sheet size is 2.7x1.2 m with a weight of 4 kg and a thickness of 1 and 2.5 cm. The Rw index corresponds to 23 dB, which is a good indicator for a material of this class. Installation of the plate is carried out with glue. The material is characterized by good ventilation. The front surface has a smooth texture, the material is suitable for finishing the walls of an apartment and a wooden house.

Kraft

Kraft is an environmentally friendly fibreboard covered on one side with waxed paper and on the other with corrugated cardboard. The size of such a plate is 2.7x0.58 m with a thickness of 1.2 cm and a weight of 5.5 kg. The Rw index has a value of 23 dB. Plates are often used as a finish.

"Eco Soundproof"

"Eco Soundproof" is a seven-layer material made of cardboard and quartz sand. It is produced in dimensions of 1.2x0.45 m. It has a panel thickness of 1.3 cm. The Rw index corresponds to 38 dB, installation is carried out on glue for plasterboard.

Soundproofing residential premises is becoming more and more important every year. And every homeowner wants to choose the best soundproofing material that protects from outside noise. Although it is difficult to choose them according to the “bad-good” principle, since many of them have a specific purpose and, to one degree or another, perform the assigned tasks.

So what is soundproofing? As a rule, noise and sound insulation is a complex multilayer structure, which includes dense layers that reflect sound waves and soft layers that absorb extraneous sounds.

In this regard, neither mineral wool, nor membrane, nor panel materials should be used as independent sound insulation.

At the same time, it is a mistake to assume that heat insulators (cork, PPS, PPE, etc.) are able to fully fulfill the role of noise protection. They are not able to stop creating a barrier against the penetration of structure-borne noise.

Even worse, if you stick sheets of polyurethane foam or polystyrene on the wall under the plaster, then this design will increase the resonance of the incoming noise.

Overview of the best soundproofing materials

Rock Wool Acoustic Butts

Rockwool Acoustic Butts, a group of companies that have been producing basalt fiber boards for eighty years, can be put in first place.

Of the shortcomings:

• Lack of moisture resistance property.
• Few sales representatives in Russia.
• High prices.
• In the process of cutting, shedding of the mineral filler occurs. This makes it necessary to process the edges of all plates with tape or tape.

In addition, if the panels are used as an independent sound insulator, then the degree of obstruction to impact and air type noise does not exceed 7 dB. Like ZIPS, panels can resonate with low frequency noise.

Owners of apartments and houses often face the problem of insufficient sound insulation in their homes. Because of this, sounds from outside become audible in the room. It interferes with sleep and normal activities. To increase the level of comfort in the room, it is required to use additional materials for soundproofing walls and ceilings. The advice of experienced builders should be considered before starting repairs.

Varieties of noise

What is the most effective soundproofing material for walls? Today, there are many offers on the building materials market, which are designed to protect against the penetration of extraneous sounds into the home. In quiet times, even minor noises coming from neighbors' apartments or sounds from the street can be clearly heard. However, loud sounds can reach you at any time of the day, even when your apartment or house is not quiet enough.

You will be interested:

Panel and brick houses, both old and new, do not differ in high-quality sound insulation of both walls and interfloor ceilings. All sounds are transmitted through the air, causing the materials of walls and ceilings to vibrate. Even minor noises coming from the outside to the owners of the house can cause insomnia. And children's crying, screams, the sound of repairs, loud music cause significant discomfort.

If the neighbors hear everything that happens in your house, then we are not talking about any comfortable living. Houses made of wood or panels transmit sounds too well, so additional noise-absorbing materials must be used here. Noise insulation of walls in a wooden house is a stage of the same importance as wall insulation and installation of communications.

How to competently isolate yourself and your loved ones from unnecessary noise outside and inside the room? Before starting work, the first thing to do is to establish the nature of the noise and its source. Based on this, you will buy soundproofing material and sheathe them with exactly those places in the apartment where the noise comes from. For example, if a strong stomp is heard from the neighbors above, then you need to treat the ceiling with noise-absorbing material. If loud voices of neighbors or sounds from the street interfere, then it is necessary to sheathe walls and partitions, etc. Noise isolation can be done independently or use the services of specialists, in any case, it should not only protect the residents of the house from outside sounds, but also not sound coming out of your room.

Noise types

There are different types of noise:

• air - sound that propagates in space through air. This is the sound of voice, musical technology, TV;
• structural - the sound that the gas and water pipeline systems in the house, the pump, the garbage chute make;
• shock - noise from mechanical actions or from movements (stomping of feet, knocking, movement of a car). Such sound is transmitted through walls, the earth's surface, solid objects.

What kind of noise should you protect yourself and others from? There are specially developed sanitary standards that allow a certain volume of sound in residential premises. The regulatory document states that for daytime the volume should be no more than 65 dB, and for night time - no more than 45 dB, while children's crying has 80 dB.

Sound level versus sound pressure table

Loudness greater than 120 dB is considered hazardous to human health. That is why it is so important to ensure peace and quiet in the home by lowering the sound transmission of walls and other building structures.

The nuances of the process to improve sound insulation

Before buying noise-absorbing products and proceeding with their installation, it is necessary to carefully inspect the walls and ceiling for defects (cracks), and also close up holes around inaccurately mounted sockets using fiberglass for this. The following factors also contribute to the increase in noise in the house:

• if the building materials themselves have low soundproofing properties;
• if the doors and window frames of the old design, or low-quality double-glazed windows;
• if finishing materials poorly absorb noise.

In order for the money and effort spent to give the expected result, it is necessary to focus not only on the sheathing of the room with absorbent materials, but also to do a number of related work:

• replace old doors with more modern ones, with elastic seals along the contour;
• change wooden windows to double-glazed windows;
• install seals on interior doors;
• cover the building from the outside with materials with high sound-absorbing properties;
• use materials with a low level of sound reflection for finishing the facade.

If you do all of the above work, then this will not only save you from unnecessary noise outside and inside, but also significantly insulate the building.

Materials for absorbing noise in the house

There are many ways to soundproof walls in a residential building. Consider the characteristics of some of them and options for their use.

Cork noise insulators

Outside, you can use thick cotton fillers, but if you need to sheathe the walls inside, then the smallest thickness of the material is important so as not to take up a lot of room space. Porous cork wallpapers or cork wood panels will do just fine with this.

Cork not only does not let noise through, but, like any tree, retains heat, and is also used as a finishing material. Corridors, hallways, children's rooms are often trimmed with such wallpaper.

Loaded vinyl (or noise block)

If square meters are especially small, then it is impossible to do without vinyl film. Its thickness is not more than 3 mm, but at the same time the film is very heavy - 5 kg per square meter. This is what provides a large noise absorption coefficient.

Loaded vinyl (noise block) - high-quality, dense, but expensive membrane

Vinyl film is flexible, resistant to moisture, and the mineral dust that is added to it absorbs sound. One layer of material is capable of delaying sound at 25 dB, two layers - more.

ZIPS

ZIPS panels glued under the wallpaper.

They are a two-layer "sandwich", consisting of panels, inside of which there is a basalt fiber with a solid gypsum-fiber sheet.

Soundproofing panel ZIPS-Module floor

Such panels have a thickness of up to 7 cm and absorb up to 10 dB.

Substrates

Soundproof underlays and underlays for wallpaper.

This thin material is easily glued to the wall and is not at all expensive, but the effect of such sound insulation will not be great.

Fiberglass

Fiberglass slabs act as the middle layer in sound-absorbing partitions.

They are placed inside the interior partitions or between the floor slab and the suspended ceiling. So that the fiberglass does not crumble during installation, it is wrapped with a special non-woven fabric.

Drywall

He also has the ability to delay sound, of course, in combination with other materials, for example, a “sandwich” of fiberboard, chipboard and drywall.

Mineral wool

Mineral wool, ecowool, basalt wool.

These are fibrous materials that absorb noise well, but have a large thickness, through which they cannot be used in a small room.

Expanded polystyrene

The material is environmentally friendly and durable. It has low thermal conductivity, therefore it is used for thermal insulation. It is thinner than mineral wool, resistant to moisture and mechanical stress. Able to delay sound at 4 dB. Often used as an insulating material in combination with others.

In general, it should be remembered that any type of noise-absorbing structure alone will not give the desired result. The more materials are combined when protecting the house from extraneous sounds, the better the effect will be.

Room soundproofing process

To completely block sound vibrations from one room to another, it is necessary to block all directions of sound wave propagation.

Walls and partitions

Most often, walls and interior partitions are isolated from extraneous noise. Various mineral wools are very easy to install, so they are used more often.

Soundproofing walls in a frame house

To do this, perform actions in the following sequence:

1. Horizontal slats are nailed to the walls, this is a crate for ventilation.
2. A vapor barrier film is glued to the crate.
3. Construct vertical racks of aluminum.
4. Mineral wool or ZIPS panels are laid between the racks. The material inside is fixed with slats.
5. Then the vapor barrier film is glued again.
6. At the end, the walls are sheathed with some kind of finishing material.

Floor

To muffle the sound penetrating into the apartment through the floor, fibrous bulk materials are used: ecowool, basalt wool, etc. A cork and rubber substrate will also be good.

Isolate the floor like this:

1. The old floor is torn off, and waterproofing is laid on the logs and between them.
2. Next, lay the material for soundproofing.
3. Then again put waterproofing material.
4. On the top give a rubber-cork substrate.
5. And then chipboard plates are laid and the space between them and the wall is compacted with felt.

Ceiling

It is possible to seal the ceiling so that the noise penetrates less, both from inside the room and from the side of the attic, if it is a private house. It is also desirable to negotiate with neighbors in a high-rise building, then the effect will be better.

Suspended ceiling soundproofing

Soundproofing the ceiling is done in this way:

1. Dismantle the old coating from the ceiling.
2. A construction stapler attaches a vapor barrier tape.
3. Next, fill the gap between the suspended ceiling and the coating with sound-absorbing materials. These can be foam boards, basalt wool, Ursa type roll insulation.
4. If the ceiling is made of wooden beams, then mineral mats are laid between the beams.
5. Sheathe the ceiling with finishing material.

findings

Soundproofing the walls in a wooden house is a necessary procedure, since in addition to protecting against unwanted noise, the above materials provide heat conservation in the home. And living in a warm and soundproof house is much more comfortable.

When doing a major renovation or moving into a new apartment, you need to take care not only of obvious things like a washbasin in the bathroom, but also of invisible factors of your comfort. Soundproofing the walls in the apartment - that's what will allow you to enjoy the silence and strengthen the nervous system!

The nervous system suffers the most from noise. Doctors diagnose insomnia, hysteria, apathy, and a decline in vitality in people who are “sick” with noise. This "disease", if you think about it, is waiting for us everywhere, it is worth stepping over the threshold - the noise of vehicles, the squabble of passengers on the bus, the rumble in the office or at the factory. Progress is certainly accompanied by an increase in the noise level! The only place we expect to find salvation from it is our own home.

However, thin walls cannot protect us even from the usual conversation of neighbors, not to mention a quarrel or a noisy feast. The maximum noise level that a person at work can carry is 85 dB, although already at such decibels it is recommended to wear protective headphones. At home, this figure should not exceed 30 dB at night and 40 dB during the day. It is not necessary to measure them - trust your feelings. If extraneous sounds annoy you, then they are too loud.

Most often, conflicts due to noise arise among residents of panel and block houses. Modern materials and technologies that do not allow extraneous sounds to penetrate your home will help you avoid quarrels. However, do not forget to make soundproofing even if the source of the noise is yourself!

On the market you will find a lot of solutions to this problem, but do not rush to fork out. You can also get rid of noise with improvised means. Your task is to eliminate the mistakes and shortcomings of the builders. Our tips may seem too simple to you, however, by following them in a complex, you will significantly improve the acoustic condition of the apartment.

Soundproofing walls in an apartment - a step by step diagram

Step 1: Outlets

First of all, pay attention to the sockets located on the inter-apartment walls. Quite often, for ease of installation, builders make a through hole in the wall to make it easier to mount sockets. It is very easy to verify the special role of sockets in breaking silence - at the moments when you hear noise, gently put your ear to the socket, and you will see that it is just the weak link.

Turning off the electricity in the apartment for a while, dismantle the product. It is quite possible that you will even stumble upon the bottom of a neighbor's outlet. Insert a pre-prepared washer made of compacted mineral wool or basalt fiber into the hole. Then apply a layer of gypsum mortar on top of the washer, leaving room for your outlet. If the wall seemed quite thin to you, you should think about moving the outlet to another place. However, if nothing bothers you, install the product in place.

It should not be used as a noise insulator - it is very dense and poorly dissipates and reflects sound, moreover, some of its types are quite combustible. If we are late with advice, then just plaster the foam properly.

Step 2: Cable Junction Boxes

In new buildings, junction boxes for connecting electrical networks are usually hidden under the ceiling in the area of ​​\u200b\u200bthe center of the inter-apartment walls. As in the case of sockets, they can be installed in through holes. Everything that prevents sounds from penetrating from the next room and vice versa is plastic covers. Alas, their sound absorption coefficient is quite low.

Finding the boxes under the wallpaper is very simple - lightly tap the screwdriver handle on the wall, a characteristic booming sound will give out the location of the node. However, if you are not an electrician by profession, it is better not to go there yourself! This business should still be handled by a specialist, otherwise you can leave half the house without light. What does not prevent you from preparing materials for soundproofing - all the same washer made of mineral wool, gypsum mortar.

Step 3: Isolate the Risers

According to building codes, the risers of water supply and heating pipelines should be closed with vibration-isolated "sleeves" at the points of passage through the interfloor ceilings. It looks like this: a pipe of a larger diameter (comparing with a riser) is embedded in the ceiling. A gap of several centimeters should form between the walls of this pipe and the riser. It is sealed with soundproofing material and non-hardening acoustic sealant. True, this is all in theory - in practice this is done very rarely!

Often, builders simply close up risers in interfloor ceilings. After some time, gaps will necessarily form between the pipe and the ceiling, through which noise will be heard. And the risers themselves perfectly transmit impact noise, which in this case is not extinguished by anything.

If the builders are simply too lazy to fill the gap between the pipe and the sleeve, immediately correct this omission. If there is no sleeve at all, clear and remove the layer of coating around the riser, trying to penetrate deeper, but without fanaticism! Then wrap the base of the pipe with asbestos cloth or fiberglass and cement it. After cutting off the excess, seal the joints with sealant.

The older the house, the more flaws you can find! Over time, cracks through which unwanted noise penetrates form at the junction of walls, floor and ceiling. As soon as it becomes possible to make a complete or partial repair, carefully check all joints, seal all cracks. After carrying out this complex of quite feasible tasks, you may be surprised how much less noise began to penetrate into your apartment.

The market can offer dozens of options. Among them there are both really effective and novelties that have not yet been tested in practice. In any case, the law of soundproofing is immutable - if you want to achieve a significant effect, you need to use several materials.

Multilayer structures should be composed of materials of different density and nature. For example, drywall reflects sound, while mineral wool absorbs and dissipates it. By the way, it is cotton and fibrous materials that have the highest sound absorption coefficient - this is facilitated by their uneven structure. Overcoming such an inhomogeneous barrier, the sound loses its strength. However, soft soundproofing materials have one significant drawback - they are too thick.

It is unlikely that you will want to lose 8-10 cm from each wall, and that is how much is required to equip a structure made of crates, cotton wool and drywall.

Semi-rigid and rigid materials have a much lower sound absorption coefficient, but they are much thinner. These include pressed rock wool boards, cork sheets, drywall, and a number of modern membranes such as stressed vinyl. Such materials should be used only in combination with each other, by themselves they will not produce the desired effect, no matter how their manufacturers praise them. It is imperative that there is also a layer of air between the layers of sound insulation - getting into such an environment, the sound is significantly dissipated.

If, after completing a set of works, you find that it has become quiet in your apartment, and only occasionally especially loud sounds are heard through the walls, it will be enough for you to apply a soundproof substrate under the wallpaper. The backing is glued like regular wallpaper, only you do not have to pick up patterns and wipe off excess glue.

Thin soundproof panels SoundGuard Ekozvukoizol with quartz sand! Only 13 mm!

The main rule in soundproofing is mass and layering. It is under this law that thin soundproofing panels with quartz filler were developed by SoundGuard. SoundGuard Ecozvukoizol panels consist of seven-layer cardboard and quartz filler - burnt sand of super fine fraction (like in an hourglass).

The thickness of the panels is 13 mm, and they weigh 1m2 - 18.5 kilograms. Due to the large weight and multi-layered panels, they provide a multiple reduction in shock and sound wave energy in the entire frequency range. In addition, this result is achieved due to the massiveness, multilayeredness, elastic-viscous consistency and free, not interconnected, filler particles.
