Scientists stated the fact that the impact of constant noise adversely affects the human psyche, does not allow him to fully relax and relax and worsens the overall condition of the body. Therefore, the issue of noise insulation of walls in an apartment and a private house with modern materials is becoming increasingly relevant. There is a huge amount of materials for sound insulation on the market. Below will be considered the most popular and efficient.

How to choose a material for high-quality sound insulation of walls in a private house

This question cannot be answered unambiguously. All types of sound insulation offered by modern manufacturers are divided into categories and types that have their own characteristic features.

Before buying a sound insulation material, initially determine the function performed by it. Material can be:

1. Sound absorbing.
2. Sound insulation.

The first type absorbs noise, ensuring their sinks inside the design. Sound-absorbing materials have a fibrous or grain base. Significant advantages are a small price, low weight, and therefore ease of installation.

Soundproofing structures reflect noise and interfere with their penetration into the room. Optimally solve the problem of sound penetration from the street. All of them are solid and heavy, so uncomfortable in the fastening process.

It is necessary to focus on the features of the room. In small rooms, the noise is spread faster, and the question of noise insulation is especially acute. In this case, the overall designs eat a useful place and reduce so a small metra.

Noise can be structural and air. The structural includes the sounds of moving furniture and falling objects, the tramp of children, etc. Air noises apply to air. These are the voices of people playing music and working equipment.

Air noise are eliminated with a thick and dense surface. Materials absorbing vibration help reduce the sounds of steps, shocks when repairing, falling. To get rid of structural interference, the sealing of individual zones with durable materials is suitable. The ideal solution will combine all types of noise insulation. This is an expensive and energy-proof process that reduces the free space, but ensuring the most qualitative result.

Important! Some modern materials combine all types of sound insulation.

Types of modern materials for noise insulation

Mineral wool is very popular for sound insulation

• Still remains one of the most popular options for noise insulation in the apartment. It is inexpensive and, according to professionals, is able to keep up to 98% of various noise. It is designed to finish most of the types of surfaces, but may lose properties due to increased humidity.
• Bung It is sound insulation plates, easily mounted on the prepared surface. Because of natural origin, it is more expensive than minvat, but for fence from shock noises is the best option. Not susceptible to rotting, prevents the reproduction of bacteria and microorganisms. With proper installation and operation will not lose its properties about half a century.
• Among the new products it is worth highlighting sHIPS Sandwich Panel (TermavoyoSoisoy) With layers of mineral wool and cladding of the Gribocarton. They are one of the best materials in the modern market with ideal sound exposure and noise absorption parameters at the same time. Very easily attached, but it is expensive and require laying in several layers.
• Sound insulation breathable Isoplaat plates. Produced from natural, environmentally friendly fibers of coniferous trees. Isolate the room both from drums and from aerial noise. Mounted on glue and are a plate of 2700 x 1200 mm with a thickness of 10 mm, weighing 4 kg and sound insulation index - 23 dB.

• Wall panels "Kraft" Completed from environmentally friendly fiberboard, with the front side of lined with shaded paper, and with an invalid-corrugated cardboard. Each sheet with a thickness of 12 mm weighs about 5.5 kg. RW is 23 dB. Suitable for finishing finish.
• Panel Economicalizol It is made from quartz sand and seven-layer cardboard profiles. The acoustic mat has a thickness of 13 mm. Weighs from 10 to 18 kg, but has a sound insulation index of 38 dB.
• Mineral Plate Shumanet Made of basalt fibers and is considered a premium class soundproofer. One side is embedded with a fiberglass layer that contributes to the preservation of the integrity of the mat and holding the basalt fibers in the same position. This characteristic is especially useful if the acoustic panel sewing is scheduled. Due to the low degree of moisture absorption suitable for use in wet areas.
• Texound appeared on the market relatively recently. Its main advantage is that due to the small thickness, it practically does not eat the useful area. The axial material is the limestone breed of aragonite, and harmless polymer compositions are used as binders that provide flexibility and elasticity. Even the thickness of the canvas is very effective and able to dissipate the sounds of large intensity, not only penetrating from the outside, but also indoor indoors. The sound insulation index is 28 dB.
• Acoustic porolon. Poropolone mats are one of the most efficient sound insulators in the budget price category. It is successfully used in concert halls, in studios and in large rooms. They perfectly absorb and disperse sound oscillations, can drown out low-frequency sounds (for example, bass music). The material is rather durable, has a wide dimensional range. The main condition when installing it is the mount directly on the basis of the wall, without additional linings. If not only the walls, but also the floor and the ceiling sound, but also the floor and ceiling, the room will become almost soundproof.

Price noise insulation

When buying sound insulators, you need to pay attention to such characteristics as:

• Density.
• Moisture resistance.
• Resistance to the appearance of fungus and mold.
• Fire safety.
• Stretch resistance and pulling.

The better these indicators, the more optimal properties will be material. Naturally, its price will be higher. Naturalness also affects the pricing - eco-friendly material is safer and more expensive.

If we consider each type of sound insulation separately, then the Sandwich panels will be the most expensive. Their average cost is in the range of 1000-1300 rubles per square meter.

• Plates based on mineral and glass gambles stand in the range of 200-300 rubles. for meter.
• Hypina sheets - 100-300 rubles.
• The price of sound-absorbing materials in rolls varies from 170 to 300 rubles.

How to save on sound insulation

Prices for noise insulation of walls in a country house with modern materials can be different, but in any case should not save on such indicators as fire resistance, moisture resistance, etc. Then the sound insulation system will serve for a long time and will provide additional housing safety.

From the beginning it is necessary to determine the view of the noise you want to eliminate. For example, if the dog is born by the dog of the neighbors, which means the noise prevents you has an aerial origin. In this case, there is no need to acquire expensive materials designed to fight several types of noise. Choose that soundproofer that eliminates only air noise. If you interfere with resting constant repair work - insulate the wall from structural noise.

Do not buy soundproofers intended for industrial and public premises. They have high technical characteristics, but for ordinary apartment, materials with lower indicators are suitable. For residential buildings, systems with sound insulation index from 15 dB are suitable. The index from 22 dB is suitable for premises with special requirements.

How to choose the best soundproofer

According to experts, the best soundproofers in the modern construction market are materials based on mineral wool or fiberglass. They skip air, do not burn, easily cut and, at the same time, for the pocket most consumers. But there is no universal material yet. Manufacturers offer dozens of options. To achieve the best effect, it is better to combine several of them. Most often in homes are used:

• To overcome air noise - ceramic brick, wood designs, drywall, foam concrete, fiberglass, special multi-layer panels, mineral wool.
• To overcome shock noise - cork materials, polystyrene foam, bitumen-cork substrates, polyethylene, etc.
• To overcome structural noise - vibroacoustic sealant, glass cholester, silica base substrates and other highly elastic materials.

The consumer is trying to give preference to the most durable and elastic soundproofers having a budget value. With proper installation, all sound insulators will create a pleasant and calm atmosphere in your home.

And if you still have doubts, look at the video with the comparative characteristics of different noise insulation materials:

Best noise insulation for auto comprehensive taking into account features

The best auto insulation is completely (for better effect) throughout the car in the complex with the repair and maintenance of parts, which may cause additional noise effects when faults. Speaking about full noise insulation, we mean the hood, trunk, floor insulation, doors, as well as ceiling and instrument panels in the cabin, except the engine compartment and outdoor insulation of the bottom and arches.
What is better noise insulation for a car, ask you - of course the complete, partial not only will not give you the desired result, but maybe in general to look at sight, and you do not feel a noticeable reduction in noise.

Materials

Materials used for noise insulation machines (see) are divided into different types that are better suitable for that or another area when the car is covered with noise insulation. And each eliminates a certain kind of noise.
What is noise insulation for auto better? Here the right choice will be the combination of materials of different types, it allows you to achieve almost complete car silent (ideally), now we will look at the types used in noise insulation:

Noise absorber

The noise absorber (sound absorber) is a type of materials intended for absorption (quenching) of sound waves from the air, with noise insulation, as a rule, the following noise absorbing species use.
It:

• Accent - a modern material is one of the main materials in the work on car noise insulation (standardplast), in addition to the absorbing noise of properties, has even properties of sound reflection and thermal insulation
• Bitoplast - is an excellent sealing and anti-slip material, in addition, due to the structure, it is an excellent noise absorber
• Isolon - (special porolon) Noise isolation of this material, in principle, practically does not differ from the accent described above. In the category of noise insulation of the company Standartplast, this material is estimated as a solid four (on a five-point scale)

Sound-insulating

The soundproofing material (sound insulation) is fundamentally different from the aforementioned noise absorbers, due to its cellular structure and an impermeable film covering the material outside. Sound insolations of this type have even sound insulation still tightness and heat retention.
These materials are most effective if they have a foil surface.

Vibodmosphere

Vibration absorbers (vibration insulation) are materials that are intended to reduce (quenching) the amplitude of oscillations of the plastic or metal surfaces of the car when driving. The basis of all these vibration-pitchers is one principle - viscosity and elasticity of the component of their material (for example, bitumen or foamed rubber).
Of these, the most common for today are the following:

• Bimastbom is a material based on a taught and bitumen composition, outside fooled by aluminum film, it is perfectly cut with scissors
• Bimastandard - This material is from the entire series, has the best elasticity. It does not require warm-up (other materials warmed when sticking with a construction hairdryer), perfectly falls into curve and any curvilinear surfaces, it does not have a foil coating.
• Vibroplast is the types of M1 (M2) - all the difference in their thickness: 1.5 millimeters and 2.3 millimeters, respectively. It is easy when installing, however, has the lowest CMP (deciphered as a mechanical loss coefficient) in this line of materials.
  Following the recommendations, the instructions of specialists on metal surfaces should not be applied
• The visomat is the absorbing vibration material based on bitumen, it is self-adhesive. It absolutely does not absorb moisture (unlike felt) and besides, it does not decide on time. However, for installation, it requires warming up the material to 50 degrees

AntiScrips

Stripping (anti-slip) plates and ribbons - they are intended to eliminate the creaking sounds arising in places of contact plastic or metal metal parts. Previously, folk craftsmen used to eliminate foam rubber, carpet, and even plasticine.
However, today this is no longer needed, you no longer have to select plasticine in a child.
Let it be better to master the modeling, you should simply go to the store of spare parts and choose:

• Madeline is a tissue material having a glue layer. Thanks to its decorative form, it can be used in the open form and for the processing of the joints that are present between the panels. Madelin is presented in the market two colors: black and gray
• Bitoplast is a material made on a polyurethane based, having a sticky layer, a thickness of 5-10 millimeters. Special impregnation of this bitoplast makes it very durable and waterproof, as well as increases sound-absorbing qualities

Liquid noise insulation

Surely you heard the names of the type of liquid fenders, anticorrosive. Materials from this group are used exclusively for outdoor insulation and additional anti-corrosion machining of the machine.
This car noise isolation is the best for processing wheeled arches or the bottom of the machine:

• It is important to remember that the outer surfaces of the machine require special attention to the owner
• And the reasons are clear to everyone, due to the constant impact of the aggressive environment, which increases in winter, and simply destroys the car body
• In order to avoid premature wear and, at the same time, perform noise insulation of the machine, and liquid noise insulation is necessary
• Liquid insulation according to the method of their application is divided into aerosol and painting coatings ("painting" means a brush or spatula)
• Such mastic materials have many necessary qualities, such as a wide range of temperature use, as well as resistance to chemical reagents, their resistance to constant mechanical impacts (here we are talking about anti-growing auto protection)
• Plus, in addition to performing anti-corrosion and anti-growing tasks, liquid insulation additionally protrudes and as a good additional noise insulation of the machine
• It makes no sense to lay out photos of each of the listed noise absorbers, since their great many and from different manufacturers they may look different

Elimination of noise

Any car has many foci in which noises have a different character. For example, in the car "Business" class, noise isolation is at a good level, but cheaper models do not boast of good regular protection against noise.
It is this problem that is the most relevant for owners of all domestic cars:

• Often they express discontent about bad and wonder how to fix it with their own hands
• Car owners decide these problems using a versatile approach
• The most common way to improve noise insulation is a car processing in addition to special material.
• Today, the assortment of materials as well as proposals of specialists in conducting such works a huge amount
• At the same time, self-insulation of the machine does not require special skills from you.
• Only the instruction and manual for the operation of your car are needed to make it easier to disassemble parts of the body, as well as get all the necessary insulators, as well as tools
• Competent noise insulation in the car includes full pasting of the entire surface of the body
• And if the standard (factory) processing has been produced, it lasts firmly and without any detachments, then additional trim can be laid (over) to the standard
• And when the factory materials are poorly adjacent to the surface or pee out, then they must be deleted partially or completely
• Emerging foreign sounds in the car are two species - noise or vibration
• Noise, hearing in the cabin, they are created by a motor, transmission, tires and an external environment
• Vibration arises due to fluctuations in machine systems, such as body panels as well as details of the finish, and occurs, for example, from the irregularities of the road
• In the fight against each of these stimuli, strictly defined materials are used
• So, noise insulation for auto what better?
• In order to obtain the greatest effect, many apply several layers of different absorbing noise of substances that stick to each other in order the vibration absorber - the noise absorber - again the vibration absorber

As correct

Noise isolation established by the rules will additionally protect your body from premature corrosion.
And for the best effect, you can first handle the metal of the body with an anti-corrosion agent, in addition, the complex processing of the entire cabin saves and money and time:

• It suits the price of maintenance stations can pay, but you can make noise insulation yourself, every owner here solves for itself
• From experience I can say that the best noise insulation of the machine gives an amazing effect if it seems insufficient, then after controlling its high-quality treated technique, ride on the untreated car, then it will seem to you "rattle", after which doubts about the need (and quality) car noise insulation disappeared by themselves
• Materials that have proven themselves as noise insulation - from KICX firm
• They were originally intended for their professional installation and were designed exclusively for specialists working in this area.
• Therefore, to meet such samples in retail trade today is practically no possible
• Meanwhile, the products of this company today have the highest characteristics.
• For example, floor processing agents in the machine, the engine compartment and door inside has a mechanical loss coefficient of 0.4, a similar indicator is high in comparison with other analogues
• Kicx vibration-pitchers are simply attached to any body surface
• And at the same time they do not require additional heating, which makes it easier and simplifies the entire processing process

Features

However, it is worth considering some nuances that professionals do not mention, and lovers may not know either forget:

Doors

The doors in the machines are most often isolated due to their large areas, as noises from the street fall into the salon at most through them:

• In addition, in many cars, especially small and inexpensive doors on sound insulation, manufacturers save, in order to reduce the factory cost of the machine
• It is important to close all the technological holes, apply special materials on the surface of the door housing, sneaking the trimming of sound-absorbing substances - this is the main component of good sound insulation doors
• Often, audio system columns are embedded in the trim, in which case the sound inside the cabin improves substantially

Wheel arches

Because of the largest floor area, as well as the arches of the wheels in close proximity to the sources of noise, sound insulation of these specific elements should be given the greatest attention. The arches are covered with thick and heavy materials, the floor must be coated with vibration-based vibrations.

Hood and trunk

Especially important is the sound insulation of the trunk of machines with tousnes of the type of hatchback. Work will consist of two main stages - vibration insulation and noise insulation. To reduce the noise of the motor operation, you need to be spent.

Motor compartment

When the engine compartment is noise insulation, it is worth considering that the materials will be exposed to the temperature effects as well as the effects of chemicals, such as oil, fuel and antifreeze, brake fluid, so the materials for the motor compartment are selected taking into account the heat resistance and are additionally covered with a layer of mastic protecting against external influences. .

Outside

Outside, the best will serve liquid noise insulation, which has advantages both in the convenience and availability of the coating, and in the ease of application, has a smaller weight in comparison with standard materials, it is better to stay and gives the machine to the machine for additional protection against rust.
Now you know what isolation is the best, how to stick out correctly and where what look at the video.

If the neighbors hear everything that happens in your house, then there is no question of any comfortable accommodation. Houses of wood or panels are too well missing sounds, so it is necessary to use additional materials absorbing noise. Noise insulation of walls in a wooden house is the stage of the same importance as the insulation of the walls and the installation of communications.

How correctly isolate yourself and your loved ones from unnecessary noise outside and indoors? Before starting work, the first thing you need is to establish the nature of noise and its source. Based on this, you will buy a soundproofing material and sow those places of the apartment from which noise comes from. For example, if severe hopot is heard from the neighbors from above, then you need to handle the ceiling with a noise absorbing material. If there are loud voices of neighbors or sounds from the street, then we need to see the walls and partitions, etc. Noise insulation can be made independently or use the services of specialists, in any case, it should not only protect the tenants of the house from the sounds from the outside, but not to give Peel the sounds out from your room.

Types of noise

Distinguish such noise varieties:

• air - the sound that extends in space through air. This is the sound of voice, musical equipment, TV;
• structural - sound that publish a gas pipeline system and water supply in the house, pump, garbage chute;
• impact - noise from mechanical actions or from movement (football legs, knock, car movement). Such a sound is transmitted through the walls, ground surface, solid items.

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

Table of sound level sound level

The volume is more than 120 dB is considered dangerous to human health. That is why it is so important to provide peace and silence into the dwelling by lowering the sound permeability of the walls and other construction designs.

Soundproofing Soundproofing Process Nuances

Before buying noise-absorbing money and proceed to their installation, it is necessary to carefully examine the walls and the ceiling on the subject of defects (cracks), also to close the holes around the inaccurately mounted sockets, using fiberglass for this. Increased noise in the house contribute to such factors:

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

In order for the funds spent and the forces to give an expected result, it is necessary to focus not only on the premium of the room by absorbing materials, but also to do a number of related work:

• replace old doors to more modern, with elastic contour seals;
• change wooden windows on double-glazed windows;
• install on interior doors seals;
• cover the structure outside materials with high sound-absorbing properties;
• use for finishing facade materials with low sound expression.

If you do all the above works, it will not only save you from excess noise outside and inside, but also a significant building will warm.

Noise absorption materials in the house

Funds for noise insulation of walls in a residential building there are many. Consider the characteristics of some of them and the options for their use.

Cork noise insulators

Outside, you can use thick cotton fillers, but if you need to sew walls inside, then the smallest thickness of the material is important, so as not to take a lot of room space. This perfectly articulate porous cork wallpaper or cork wood panels.

The plug not only does not miss the noise, but also, like any tree, retains heat, and is also used as a finishing material. Such wallpaper often discharge corridors, hallways, children's rooms.

Loaded vinyl (or shoe)

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

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

The vinyl film is elastic, resistant to moisture, and mineral dust that is added to it, absorbs sound. One layer of material is able to delay the sound of 25 dB, two layers - more.

Zipse

Zipse 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 dry-fiber sheet.

Soundproof Panel Zipse Module Paul

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

Substrate

Soundproofing liners and substrates under the wallpaper.

This thin material easily glued onto the wall and is not quite expensive, but the effect of such sound insulation will not be large.

Fiberglass

Fiberglass plates perform the middle layer in sound-absorbing partitions.

They are laid inside interior partitions or between the slab overlap and suspended ceiling. So that the fiberglass does not face when installed, it is wrapped in a special nonwoven cloth.

Plasterboard

It also has the ability to delay the sound, of course, in a complex with other materials, for example, "sandwich" from DVP, chipboard and drywall.

Mineral wool

Mineral wool, Equata, basalt wool.

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

Foamed polystyrene

Material is environmentally friendly and durable. It has a low thermal conductivity, therefore it is used for thermal insulation. It is thinner than mineral wool, resistant to moisture and mechanical effects. Can delay the sound of 4 dB. It is often used as an insulating material in a complex with others.

In general, it should be remembered that one kind of noise-absorbing design itself will not give the desired result. The more materials are combined when protecting the house from foreign sounds, the better the effect will be.

The soundproofing process of the room

To completely block sound oscillations from one room to another, it is necessary to overlap all the direction of the propagation of the sound wave.

Walls and partitions

Most often from extraneous noise, the walls and interior partitions are insulated. Various mineral wools are very simple in montage, so they are used more often.

Noise insulation of walls in a skeleton house

To do this, perform actions in such a sequence:

1. Horizontal rails are nailed on the walls, this is a ventilation lamp.
2. The crate is glued with a film for vaporizolation.
3. Construct vertical stands from aluminum.
4. Mineral wools or zips panel are laid between the racks. The material inside is fixed by rails.
5. Then the vapor insulation film is glued again.
6. At the end of the wall are trimmed by any finishing material.

Floor

To muffle the sound penetrating the apartment in the floor, use fibrous volumetric materials: eco-friendly, basalt wool, etc. There will also be a good substrate from traffic jams and rubber.

Isolate the floor so:

1. The old floor is lying, and the lags and between them are laid waterproofing.
2. Next laid material for sound insulation.
3. Then they put the waterproofing material again.
4. On the top give a rubber-cork substrate.
5. And then laid the chipboard plate and the space between them and the wall seal felt.

Ceiling

Seal the ceiling so that the noise penetrates less, you can from the inside of the room, and on the side of the attic, if it is a private house. With neighbors on a high-rise building, it is also desirable to agree, then the effect will be better.

Noise insulation suspended ceiling

Noise insulation ceiling is done in this way:

1. Remove the old coating from the ceiling.
2. The construction stapler is attached to the ribbon for vaporizolation.
3. Next fill the gap between the suspended ceiling and the coating sound-absorbing materials. These can be foam plates, basalt wool, URSA rolled insulation.
4. If the ceiling of wooden beams, mineral mats are placed between the beams.
5. Ceiling with finishing material.

conclusions

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

First you need to consider the advantages of quality sound insulation. Noise absorbing materials ideally must provide:

• the ability to relax and relax;
• the absence of extraneous sounds that interfere with focus on a particular occupation;
• full sleep.

It is impossible to achieve full 100% insulation of noise, in addition, there is no such need. It is enough to reduce foreign sounds to the level when they do not cause irritation and do not interfere with a full-fledged rest. With this task, the materials for noise insulation will be perfectly.

It is known that noise is sound fluctuations in air. They are able to influence a person, and most often negative.

To the sounds causing irritation include:

• loud conversations behind the wall of neighbors in the apartment;
• sounds of power tools when performing construction and repair work;
• household appliances activities;
• strying noise from the street;
• work of communication systems;
• many other unpleasants for our hearing action.

Materials for noise insulation, with the help of which it will be possible to ensure high-quality sound insulation of walls and partitions in a new building or a long erected residential structure are diverse. These include foam plastic, polystyrene foam, polyurethane foam, mineral wool and traffic jam. You will learn about them in this article.

Polyfoam is a modern product for soundproofing an apartment or at home. This foamed plastic gas-filled white mass.

Its main volume is occupied by gas, the density of which is much lower than the density of the polymer - the main raw material. This causes high heat, sound insulation properties of foam.

Specifications and properties of foam

The foam is produced both domestic and foreign manufacturers. KNAUF corporation produces its inhibit method from foamed polystyrene. Each cell consists of dense cells, and in each cell there is 98% air and 2% polystyrene.

If you need a foam, then products that are produced from ecological raw materials can be used as an example. Antipiren is added to the composition, because such a material:

• does not bother;
• not subject to rotting;
• it is not afraid of the effects of microorganisms;
• has a high service life.

Polyfoam applies to the number more in demand when insulated partitions in the apartment. First of all, this is due to its physicochemical properties, safety and operation characteristics.

The table below describes the main parameters.

Thanks to modern technologies and equipment, there is currently a production of foam of various mechanical strength, density, resistance to all kinds of impact. Its products from it are safe for humans, so widely used in the product industry, they pack goods and products intended for our power supply.

Polyfoam is widely used in other industries and has the following advantages:

• resistant to moisture and aging;
• it is not capable of influencing microorganisms;
• it is easy to work with it, it is cut by a hand saw or a knife;
• easily gluits with other materials intended for partitions and walls in the apartment or outside the house;
• simple in installation.

Polyfoam is a waterproof material, but it has a high figure of breathability. The temperature in which it is is not capable of providing negative impact on the properties of the material. For example, at a temperature indicator, 90 degrees Celsius foam will not change its properties for a long period.

Many developers choosing materials for noise insulation in a residential room, stop their choice on the foam. First of all, it is necessary to note its operational and technical properties:

1. Low thermal conductivity indicator, due to which the air is evenly distributed inside the material.
2. Durability. Under all operating conditions, the foam will last long. Even over time, he is not able to change its properties.
3. Resistance to various destruction - weak acids, alkalis, moisture. It is important that the material is chemically neutral.

Industry Releases GOST 15588-86 Led in the table of foam brand.

And indicators on physicomechanical properties must comply with the norms of the GOST, which are listed below in the table.

In order to establish a foam on the wall, a special glue or a dowel with a wide hat apply.

Consider the first option. Some experts prefer dry mixtures on a cement basis, which are distinguished by their durability, reliability and high level of adhesion.

But you can also use aerosol polyurethane types. The laying technology consists of the following steps:

1. The plates are placed on the starting bar, which is fixed around the perimeter of the surface being processed. Do this with a dowel, step is 300-400 mm.
2. The surface should be clean, without dust and dirt residues.
3. Break glue. On the package there is an accurate instruction: the mixture is suited in cold water and stirred using a construction mixer. The composition is then left for 5 minutes, for ripening, and re-stirred.
4. With the spatula, the glue is applied to the plates, evenly distributing it around the perimeter and several slaps in the middle.
5. Polyfoam put on the bar and pressed strongly in those places where glue is.
6. It is necessary to carefully monitor the slate skew. You can control this process using a level. Inaccuracies corrected with light tapping with hand or hammer on the stove. But do not forget to do it through the wooden bar, so that the foam does not destroy.
7. Plates are placed on the bottom horizontally. The subsequent row is already performed in a checker order, so that the stacks are formed.
8. The seams are filled with glue, existing surplus with a spatula are removed. Next, the glue is allowed to dry, sometimes it takes 2-3 days.

The second option makes it possible to fix the foam with a special dowel. It has a wide hat, why its contact with the surface increases significantly and it reliably presses the slab to the wall. The perforator in the wall is drilled by a hole of the required depth. There should be 5 such holes on the sheet - in the corners and in the middle.

Dowel must drown in the foam, and not oppose it. Otherwise, when putty, you will have to spend a lot of material. Only do not impose much, otherwise the foam will crack.

Sometimes for the reliability of professionals, foam plastic stick onto the wall and fix each sheet of dowels. This method is distributed in cases where the surface of the wall is uneven. Then the glue is applied at the corners and in the center of the plate. Then the foam is attached to the base. And further at the same points is attracted by plastic dowels - "fungi", adjusting the pulmonary sheet on the plane and fixing it in a given position.

Many specialists believe that the foam is better suited for soundproofing partitions and walls. It is easy to install, does not require knowledge of special skills, it is easily cut with a knife and serves a long time.

Before you begin the descriptive characteristics of the polystyrene, it is necessary to distinguish between it and the foam. There is an opinion that this is the same sound-absorbing material, since the composition is identical - air and styrene (hydrogen + carbon).

So, the differences between expanded polystyrene and foam are as follows:

1. Various manufacturing technology - the first is performed when processing dry steam, the second - by melting the granules of polystyrene foam.
2. Differences in the characteristics of production techniques.

Specifications and properties of polystyrene foam

This product is also known in construction, as well as foam. Many choose precisely polystyrene foam, because he has:

1. High strength - the material will never crumble, the bending resistance is 5-6 times higher than the foam. That is why it is better to use it in places, which sometimes are mechanically exposed, for example, for partitions in the apartment.
2. A high sound insulation indicator that is due to the presence of a set of emptiness in the polymer.
3. The density is several times higher than the parameters of the foam, so its weight is greater.

Polystyrene foam is the material whose characteristics in some cases are superior to the parameters of foam. Despite this, the last polymer is recommended to be used in cases with low loads, where the use of expensive materials is not required.

In accordance with GOST 30244-94The fire hazardousness of the unprocessed expanded polystyrene has a combustible class G4. It means that his ignition may occur:

• flame matches;
• soldering lamp;
• sparks of autogenous welding.

Material retains energy from heat source, spreads fire and initiates a flame enhancement. The fire safety indicator depends on the additives that are used in the production of material. Temperature fluctuation mode is determined by the certification class.

The usual polystyrene foam (G4) in a short time reaches 1200 ° C, and having special additives (anti-epires) in its composition, reduces the combustion temperature and corresponds to the gramificence class G1.

With burning polystyrene, a toxic smoke is formed. In the usual material, it is 36 times more than that of wood, in particular, cyanorod, bromometroof and other substances are distinguished. And depending on impurities, which are part of polystyrene foam, smoke acquires various intensity and degree of excretion of harmful substances.

Products made of polystyrene with a combustible class G4 are not allowed for use in construction. The work is used only by special additives modified by special additives. It is called self-fighting and has a combustible class G1. Domestic manufacturers are marked with the letter "C" (PSB-C).

To ensure high-quality sound insulation of partitions in the rooms, it is recommended to pay attention to the polymer whose thickness is 2-3 cm. When choosing, it is necessary to take into account that with increasing thickness will increase soundproofing qualities. Before buying, breaking the piece of material if it has granules in the form of the right polyhedra, the polymer is distinguished by high quality.

Consider in the table below the size, volume and weight of sheets of polystyrene foam production of KNAUF Corporation:

Plates made of polystyrene foams consider one of the most affordable sound insulators in the construction market. They withstand the load 6 t / m 2, easy to install and durable.

Polyurene Foolder

Materials for noise insulation include such material as polyurethane foam. This is a kind of plastic with a cellular foam structure. The composition of the material prevails a gaseous substance, the content of which varies from 85% to 90% of the total mass. The polymer consists of thousands of cells, each of which is isolated from the rest.

Severe two types of polyurethane foam:

1. The foam rubber is the elastic form of the presented polymer, the density of which reaches from 5-35% per 1 m 3.
2. Hard polyurethane foam, presented in more than thirty brands (suitable for insulation of partitions in the rooms).

The characteristics of the rigid polyurethane foam used for the soundproofing of walls and partitions in the premises include:

• low thermal conductivity;
• low weight;
• high level of strength;
• no need to use fastening elements;
• high anti-corrosion protection of metal structures;
• cold bridges in this polymer are absent;
• insulation may have different shape;
• confirmed environmental friendliness - in accordance with hygienic standards it can be used in the refrigerator for food.

Polymer spraying is possible to many materials (in which its versatility manifests itself) - on a tree, glass surface, metal and other coatings. It does not matter the surface configuration. An important point is the resistance of the polymer to acid, the ability to use in the ground.

Working with polyurethane foam must be remembered that it is not desirable for him to directly exposure to sunlight.

The durability of the PPU is 25-30 years, subject to the rules of use. Confirmed excellent climate-resistant material parameters, in particular its resistance to moisture. In the class of flammability, it refers to the categories of G1-G4. The polymer is anti-epires that prevent the spread of fire.

When exposed to open fire, the material is peculiar to burn. But in its deep layers does not spread the flame. This cellular structure of the material is explained and the fact that trichloroethyl phosphate is present in its composition - antipiren. Therefore, this material is allowed to apply in kindergartens and school institutions.

Also, polyurethane foam is distinguished by resistance to microorganisms and rotting processes.

The physical properties of this material can be considered in the following table.

The popularity of such a building material is explained by the fact that specialists have the opportunity to get it right at the site of application. Liquid products, mixing in certain proportions, create a chemical reaction with simultaneous foaming. That sometimes during construction processes is very convenient and physically justified.

It should only be remembered that specialized equipment and personal protective equipment need to work with polyurethane foam.

Basalt Vata.

Sound-absorbing materials are mineral wool, known as basalt wool. It is used for soundproofing walls, decorative partitions and ceilings in the apartment. Products made from it are supplied in the form of plates or rolls.

The table below shows the types of components and specifications.

Named material has a lot of advantages, among which thermal insulation is distinguished. This quality is confirmed by a low thermal conductivity coefficient, the lowest heat loss of all heat insulators. In addition to the above qualities, there are still a number of advantages:

1. The material is not destroyed when exposed to an aggressive medium or chemicals. Basalt wool externally does not change its appearance and does not lose qualities. She is not afraid of fungi and microorganisms.
2. The durability of the material is provided with a manufacturer's warranty, it reaches 30-40 years. True, experts say that it is possible to add a couple of dozen years to this deadlines. Its fibers have a small length, they are chaotic in basalt wool. And this provides high mechanical characteristics over long years of operation.
3. The structure of the material is not terrible vibration.
4. Basalt wool is better to carry ultraviolet.
5. The temperature differences do not affect the technical characteristics of the material.
6. Basalt wool perfectly absorbs outsiders, loud and sharp sounds.

The table shows the sound absorption coefficients of some building materials.

The use of high-quality mineral wool can not be a guarantee of reliable sound insulation, since the material is an integral element of the noise absorbing design, which is required to consider proven techniques.

Mineral wool plates on synthetic binding are manufactured by GOST 9573-96 and have the dimensions given in the table.

Physico-mechanical material indicators must comply with the following characteristics.

Product labeling produce GOST 25880. With the obligatory indication of the time of release and the conventional notation. Each package is the sign "Bear from moisture" by GOST 14192.. Basalt wool refers to the number of non-combustible materials, so it does not release toxins or other harmful substances when heated. An equally important indicator is the smoke-forming ability of basalt, which does not highlight smoke. It is mounted quite simply - the stove is stacked between profiles and keeps perfectly. It is also possible to fix it with a cement-based glue, as in cases described above with foam or expanded polystyrene foam.

Many believe that basalt wool is harmful to health. You can argue with this. It does not distinguish odors, according to the properties is similar to Natural Stone Basalt. True, phenol and formaldehyde resins are used as bindings, but if the necessary norms and demands and demands remain in the material, harmful substances remain in the associated state. Therefore, it is possible to state the fact that basalt wool is harmless to human health and its surrounding medium.

An excellent option to solve the problem of sound insulation is to cover the walls of the plug.

This coating is applied to the number of environmentally friendly materials, since the material has natural composition. The plug is capable of holding heat, has reliability and durability. No less important dignity is aesthetic appearance.

Tube is on sale in two types:

1. Sound insulation panels.
2. Rolls (film).

For its mounting to the walls, it is necessary to use a glue composition. The inner structure of the material is represented by a huge number of tiny bubbles, remarkably holding inside heat. In addition, such a structure contributes to the improvement of the acoustic picture in the rooms.

Soundproofing panels possess such indicators:

• light weight - the material is light, not sinking in water;
• elasticity - even after providing high pressure, the panel returns back to the original form;
• tightness - due to the presence in the composition of wood bark, the material becomes impermeable for substances in a liquid and gaseous state;
• high waterproof rate;
• hypoallergenia - the stove does not absorb dust, therefore it is not able to provoke allergic reactions;
• fire resistance - it does not contribute to the spread of fire, in addition, during fire, it does not allocate toxins, which is confirmed SNIP 23-03-2003;
• the inner structure of the plate provides remarkable soundproof properties, so it will be possible to provide silence in the house and calm;
• durability due to the unique structure of noise insulating plates and their qualities - elasticity and elasticity. Even after a long period of time, the material will not lose its initial properties.

The plug is a natural product that binds the link in which from polyurethane. The thickness of the plate depends on the variety - varies in the range from 0.6 to 1.2 mm. It is recommended to protect the material from the long exposure to sunlight. The ability of traffic jamming of vibration provides a significant reduction in the noise indoors where it is used.

Soundproofing of the room using traffic jams is a great option for new buildings, which do not provide for the use of special materials to ensure noise insulation. The plug can be used for walls, ceilings and decorative partitions, as evidenced by numerous reviews of specialists.

The characteristics of this material can be found in the table.

For more detailed explanations, we studied this material and described our observations and research in the article ""

If you choose sound-absorbing materials for walls, decorative partitions or ceilings in a new building, then it is necessary to be based not only on the operational properties or the advantages of a polymer, it is even recommended to pay attention to the technical properties of the product. The table presented includes a comparison of all the considered technical terms. For the analogy, the following indicators were used: density, thermal conductivity, porosity, durability, operating temperature. Taking into account each of these parameters, you will make the right choice in favor of this or that product. Such properties of sound insulation materials

So, all listed sound insulation materials are able to show their qualities only in the correctly assembled design. They differ in high parameters for each indicator, which causes the popularity of their use.
