Materials for thermal insulation: comparison of types and types. Electrical, sound and noise insulation materials Insulating materials for walls and floors

The problem of insulation outside and inside the dwelling is acute in any climate zone. The main task is to choose the right thermal insulation material. And it's not as easy as it seems. It is necessary to know such properties of insulation as thermal conductivity, water absorption, strength, service life, as well as the subtleties of installation.

The process of insulation usually affects all the structures of a dwelling - walls, floors, ceilings. External insulation or combined insulation (inside + from the street side) is preferable. Thermal insulation only from inside the dwelling is undesirable, since the dew point will move even deeper into the wall or move to the border of the wall and insulation.

Thus, it is not enough to optimally select a heat-insulating material; it is necessary to properly install it.

Important. The stove (inside) and chimney (outside) also need to be insulated. If this is not done, the walls close to the furnace will crack. An uninsulated chimney is covered inside with condensate, which, mixing with exhaust gases, turns into acid. It quickly corrodes the walls of the chimney, rendering it unusable.

What are heaters

Modern thermal insulation materials are diverse. In private housing construction, along with high-tech insulation (polyurethane foam, penoizol), natural insulation is still used. This is due to their availability and low cost.

The following thermal insulation materials are used inside and outside to insulate walls, ceilings and floors:

  • expanded clay (concrete attic and interfloor ceilings they are insulated with this material from the inside, expanded clay is also poured into the cavity between the walls);
  • cork (wall and floor insulation from the inside);
  • ecowool (walls, floors, attic - it is preferable to insulate from the inside due to such material properties as hygroscopicity);
  • mineral wool (walls, floors, attic floor- suitable for insulation both inside and outside);
  • polystyrene (walls outside, concrete screed);
  • penoplex (due to such a property as low water absorption, it is possible to insulate walls from the inside and outside, concrete screed, roofing, interfloor and attic floors);
  • penoizol (walls and floors - it is preferable to insulate from the inside, the property of penoizol to absorb water well requires accuracy with external insulation);
  • polyurethane foam (any surface, including metal and plastic pipes hot and cold water supply - insulation inside and from the street).




Mineral wool refers to non-combustible insulation, so it is used for thermal insulation of stoves and chimneys.

Thermal insulation materials for walls

Wall insulation is best done outside during the construction phase. Wall thermal insulation materials are divided into natural and artificial. There is also a division into bulk, plate / mat, roll and foil roll.

Natural heaters include:

  • mats and roll insulation from hemp and algae (rare and expensive insulation, suitable for thermal insulation of walls);
  • clay plaster (adobe);

Artificial thermal insulation materials for walls are:

  • expanded polystyrene (regular and extruded);
  • polyurethane foam (sprayed thermal insulation);
  • penoizol (poured into the cavity);
  • ecowool (cellulose loose insulation);
  • mineral wool (stone/basalt) in rolls, slabs, mats;
  • thin roll insulation with or without foil.

Characteristics of thermal insulation materials (comparative) can be seen below.

This parameter is measured in W / m * K. The lower the thermal conductivity, the better material keeps heat in the living room.

This parameter is directly related to the density of the insulation. Loose thermal insulation has a much lower thermal conductivity than solid insulation:

Styrofoam 0.045

Penoplex 0.032

Polyurethane foam 0.019 - 0.035

Penoizol 0.028 - 0.038

Ecowool 0.038 – 0.045

Mineral wool 0.045 - 0.07

Measured in %/day. An important technical characteristic showing how quickly thermal insulation materials absorb water. A high score is not a reason to stop using it. Insulation with high water absorption capacity requires careful double-sided waterproofing.

Comparative characteristics of materials:

Mineral wool 2

It is measured in mg/(m.h.Pa). The characteristic shows how much the material breathes. All breathable insulation can be used for thermal insulation wooden walls. According to experts, the vapor permeability of the insulation is not always useful. Often the complete clogging of pores and the organization of micro-ventilation are much more effective.

Comparative characteristics of vapor permeability:

Styrofoam 0.018

Polyurethane foam 0.04 - 0.05

Penoizol 0.21 - 0.24

Mineral wool and ecowool 0.3

Durability

This parameter is very important for thermal insulation. If the other characteristics of several heaters are the same, then it is this parameter that tips the scales in favor of choosing the most durable insulation.

Styrofoam ≤ 13

Penoplex up to 40

Polyurethane foam up to 50

Penoizol up to 75

Ecowool at least 50

Mineral wool at least 70 years old

By analyzing these data, one can personal opinion about different heaters and choose the ones that are best suited for your purposes.

Important. natural thermal insulation materials from hemp and algae have low thermal conductivity, but they absorb water well, which, coupled with high cost, makes them unpopular for insulating walls from the outside and from the inside.

The exception is expanded clay and cork. The first is poured between the walls in the well masonry and spilled with cement milk. This prevents the material from settling and increases its strength. This wall insulation is cheap, buying it is also not a problem. To reduce the thermal conductivity of insulated walls, it is necessary to mix expanded clay of various fractions.

Cork is an excellent thermal insulator. Its properties are such that cold cannot penetrate into an insulated room, and heat cannot leave it. In addition, it does not absorb water and has an attractive appearance. True, the cost of such a heater is significant, so it is more often used for finishing walls with additional thermal insulation properties.

Floor heaters

Of the many heaters for thermal insulation of the floor, expanded clay and foam plastic are often used (less often foam plastic, since it is much more expensive than foam plastic). Cork can also be used to insulate the floor (as a substrate for linoleum or carpet covering, as well as finishing). The properties of this material are unique. It does not absorb water spilled on the floor, perfectly dampens noise, has a velvety texture to the touch. Its surface is never cold.

Expanded clay is used to insulate the floor in the attic. It strongly absorbs moisture, so it is necessary to make double-sided waterproofing. Because of this characteristic, it is not recommended to insulate a wooden hemmed attic floor with expanded clay (material that accidentally picks up moisture increases significantly in weight).

High density foam is ideal for insulating floors in cement screed. The same can be said about penoplex, although it is more expensive, so it is used much less frequently for floor insulation.

Mineral wool is another insulation that can be used to insulate both the floors between floors and the attic. Due to hygroscopicity, mineral wool requires double-sided waterproofing.

The technology of floor insulation with foam plastic includes several stages:

  1. Preparation of the base (cleaning from debris and dust).
  2. Floor treatment with deep penetration primers.
  3. Laying waterproofing film(required with entry to the walls, the joints are glued with construction tape).
  4. The foam is fixed to the floor with glue, the joints are coated with sealant.
  5. Be sure to leave a gap between the walls and the insulation.
  6. A special reinforcing mesh is installed on the insulated floor (it is mounted on racks and is located at a distance of 2.5 - 3 cm above the level of insulation).
  7. It remains to fill the floor with a self-leveling mixture.


Ceiling heaters

It is possible to insulate the ceiling from the inside only if the height of the room allows it. For these purposes, aerated concrete slabs are well suited. They weigh very little and are easily attached with foam board adhesive. The joints are covered with sealant. Additionally, foil insulation can be laid.

Styrofoam and foam plastic, as well as mineral wool, are used only from the side of the attic (as described above).

Heat insulating roll materials

Thin rolled polyethylene foam insulation is a weak obstacle to cold air entering the room through micropores and cracks. However, foil roll materials- a great addition to the warming cake.

Foil thermal insulation (penofol, foil isolon) laid on top of any insulation will play a dual role - repulsive thermal insulation and waterproofing. In this case, there is no need to purchase separately waterproofing materials.

Advice. Rolled foil heaters are demanding for installation. They will not work if, for example, lining is laid directly on them. A working gap between the foil and finishing. Therefore, on top of rolled foil insulation, a crate is always made with a thickness of bars of at least 3 cm.

Various types of heat-insulating materials (bulk, roll, slab) allow for insulation various surfaces- Walls, ceilings, floors. Refractory thermal insulation (non-combustible) is suitable for insulating furnaces (not the furnace itself, but nearby walls are insulated).

From year to year, prices for energy resources are inexorably growing, and the level of income of the population remains practically the same. Looking at the unbearable bills for heating a house or apartment, it comes to understanding that the problem needs to be solved on its own - by warming the living quarters.

For this purpose, they can be used different kinds insulation for the walls of the house from the inside and outside.

Let's take a closer look possible options materials for insulation, their advantages and disadvantages.

Insulation work is best done in summer period when the air humidity is at its lowest.

Walls for insulation in the room must be perfectly dry. Dry them after additional plastering, finishing work surface leveling can be done using building hair dryers and heat guns.

Stages of surface insulation:

  1. Surface cleaning decorative elements- wallpaper, paint.
  2. Treatment of walls with antiseptic solutions, priming the surface with deep penetration into layers of plaster.
  3. In some cases, when installing polystyrene foam and electric heating elements, the walls are pre-leveled with waterproof plaster for bathrooms.
  4. should be carried out according to the instructions prescribed by the manufacturer for this type of material.
  5. Mounting the protective partition for application final finishing, or surface coverage construction mesh, her plastering.
  6. Creation of a single composition with overall design premises.

Wall insulation inside the house is one of the most effective ways to protect your home from the penetration of cold and the negative effects of condensate, the main thing is to observe technological sequence stages. You can read more about the technology of home insulation from the inside in

Tips for insulating walls in an apartment - an analysis of common mistakes:

Warming a house, made with the help of even not the most expensive materials, is not a cheap pleasure. Many types of heaters are now available for internal works, which are presented in an extensive price range. Therefore, choose an inexpensive and quality material won't be difficult.

Warm house in winter period and comfortable coolness during the hot season, as well as reduced bills for utilities will show that the thermal insulation of the room is done well and with high quality.

What material did you use to insulate the walls of the house? What guided the choice and are you satisfied with the result? Please tell us about it in the comment block. There you can also ask a question on the topic of the article, and we will try to answer it promptly.

Soundproofing the walls in the apartment modern materials for which today can be found in hardware stores, is becoming more and more relevant. This is explained simply - fences in multi-storey buildings typical houses are not able to fully protect the home from external street noise and from sounds coming from neighboring apartments.

medical scientists It has long been noted that the presence of constant noise has an extremely negative effect on the human psyche, not allowing him to get complete relaxation and rest. That is why, unable to withstand the constant sound pressure, many city residents, especially those who live in panel houses, begin an active search for a suitable soundproofing material that will meet all the requirements for its use in apartments.

Almost all modern acoustic materials are made on the same fundamentals, which is traditional. However, they have undergone significant improvement due to recent production technologies.

To date, very a large number of new soundproof materials, and it is simply impossible to cover the characteristics of all on the scale of one article. Therefore, attention will be focused on the most effective ones, which are used in an apartment.

Thin soundproofing MaxForteSoundPro

When the area of ​​​​an apartment or room does not limit the choice of materials, and you can install sound insulation of any thickness, this is convenient. But what if you can't afford to spend precious inches of living space?

In this case, the innovative MaxForte SoundPRO thin soundproofing material will suit you. It has a thickness of only 12 mm, while in terms of its characteristics it is able to compete with sound insulation with a thickness of 5 and even 10 cm! MaxForte SoundPRO is the latest material designed specifically for soundproofing residential and industrial premises.

Specialists from the Research Institute of Building Physics and the Department of Acoustics of the Faculty of Physics of Moscow State University took part in the development of the material. In the manufacture of MaxForte SoundPRO, all important points were taken into account for effective work material: the optimal density was selected (with a low density, the sound will pass through, if it is too high, along the “skeleton”), the length of the fibers, their thickness. The sound-absorbing layer is calibrated and uniform over the entire area. The material is completely non-flammable. The composition does not contain harmful phenol-formaldehyde resins and any adhesives. Therefore, in addition to excellent soundproofing properties, MaxForte SoundPRO is safe for health.

MaxForte SoundPRO gives an increase in sound insulation from both air (loud TV, a crying child, screams of neighbors) and impact noise (noise from trampling, rattle of furniture, falling objects). It can be used for soundproofing ceilings, walls and floors, which will give a significant increase of up to 64 dB!

Mounting thin sound insulation very simple, and not only professionals can handle it, but anyone who has ever held a hammer drill and a screwdriver in their hand.

MaxForte SoundPRO is mounted on the wall using ordinary plastic dowel mushrooms, which can be purchased at any hardware store. It is hung on the wall using the butt-to-butt technology, after which it is covered with a layer of GVL (gypsum fiber sheet). All seams of the sheets must be glued with a special vibroacoustic non-hardening sealant. After the soundproofing is sewn up with a layer of GKL (gypsum plasterboard). seams GVL sheets and GKL should be in a run, that is, not the same.


Visually about the installation of thin sound insulation MaxForte SoundPRO you can see in the video.

Thin wall soundproofing with panelsSoundGuard EcoSoundIsol

EcoZvukoIzol SoundGuard panels are unique material for soundproofing walls and ceilings, which allows you to achieve silence in the apartment and not lose usable space.


SoundGuard EcoZvukoIzol panels are made of a durable multi-layer cardboard profile based on the honeycomb principle, which are filled with thermally treated mineral quartz sand. The quartz filler used is very fine, exactly the same as an hourglass. It is this filler that makes it possible to achieve an impressive weight of the panel - more than 18 kg per m2, and according to the laws of sound insulation, the heavier the material, the worse it transmits sound (cotton wool transmits sound very well, for example brick wall or a steel door is much worse). Except weight quartz sand due to fine fraction perfectly extinguishes and absorbs almost all frequencies of sound - from air to shock.

How to mount panelsSoundGuard EcoSoundIsol?

Installation of panels is very simple and almost anyone can handle it. are attached to the wall using SoundGuard DAP acoustic dowels, which are hammered into holes pre-drilled through the panel in the wall. After that, all seams and joints are smeared with sealant and the entire wall is sewn up with drywall.

Mineral noise absorbing material "Shumanet-BM"

This soundproof the material made from basalt fibers is considered to be premium grade mineral sound absorbing board. One side of the mat is laminated with a fiberglass layer, which helps to preserve the integrity of the slab and keep the internal basalt fibers in one position to prevent their small particles from entering the room. This is especially important in cases where the sound-absorbing material will be covered by perforated acoustic panels.


Packing of soundproof boards "Shumanet"

Plates « Shumanet BM" are produced in accordance with the requirements of SNiP 23 03-2003 Noise protection. They have the following technical and operational characteristics:

Indicators
Standard plate size (mm)1000x500 or 1000x600
Plate thickness (mm)50
Material density (kg/m³)45
Number of boards in a package (pcs.)4
Area of ​​boards in one package (m²)2.0 or 2.4
Weight of one package (kg)4.2÷5.5
Packing volume (m³)0.1 ÷ 0.12
Sound absorption coefficient (average)0.95
Flammability (GOST 30244-94)NG (non-flammable)
Water absorption at partial immersion in water for 24 hours, in% of the total volumeNot more than 1÷3%

Acoustic tests to determine the sound absorption coefficient were carried out in the measurement laboratory of the Moscow Research Institute of Building Physics at the Russian Academy of Architecture and Building Sciences.


The basis of "shumanet" are basalt fibers

Having a low degree moisture absorption, this soundproofing material can be used not only in rooms with normal humidity but also, for example, in the bathroom. In addition, it is excellent for soundproofing tension and suspended ceilings, and, of course, walls and multilayer partitions made in the form of a sandwich of drywall, plywood, fiberboard and other sheet materials.

Soundproofing walls using "Shumanet BM"

The installation of the plates of this sound insulator takes place according to the same principle as all types of mineral wool. However, one must take into account the fact that the material will be used primarily as sound absorber, and only then is considered as an additional insulation.

Work is carried out in the following sequence:

  • On the prepared one, markings are made to secure the elements of the crate. Since the width of the mats is 500 mm, and they should stand between the bars by surprise, the distance between the guides should be 450 ÷ 480 mm. If mats 600 mm wide are purchased, then, accordingly, the distance between the bars should be 550 ÷ 580 mm.
  • Further, the elements of the crate themselves are fixed, but at the same time, in order not to weaken the basic qualities of the soundproofing material, experienced craftsmen advised to perform a series simple recommendations:

- For the crate, it is best to use a wooden beam, and not metal profiles, since metal is a good conductor of sound, it can resonate, and wood tends to muffle sound waves.

- In addition, in order not to create bridges for the passage of sound, it is recommended to make spacers between the wall and the battens of a thin soundproof material, for example, felt or strips basalt wool 8 ÷ 10 mm thick.

- If, nevertheless, a metal profile is chosen for the crate, then it is better to move it away from the wall with a soundproof gasket by 12 ÷ 15 mm.


- In the event that the area soundproof the room is large enough, and it is possible to take out the crate for sound-absorbing material and cladding 100 mm from the wall, then you can use special details - hangers. They are screwed to the wall through wooden spacers, and the bars are already fixed in them.

Another option is the use of special suspensions, which are designed specifically for noise-absorbing structures. Structurally, such a product already has a special damper layer, which effectively dampens vibrations without transferring them to the frame guides.


Special suspension used for soundproofing work

If a guide bars fixed in the above way, then the sound insulator mats are mounted in two layers. The first of them is installed behind the elements of the crate, close to the wall, and the second - between the guides.


Two-layer placement of shumanet panels
  • Ultimately, upon completion of the installation of the Shumanet BM panels, the walls should look like this:

Next, over the mats soundproof material is fixed vapor-permeable diffuse membrane. Then they proceed to the installation of drywall or plywood sheets, which, in turn, will become the basis for finishing work. However, it is quite possible to replace this layering by fastening directly to the guide rails of a wooden decorative lining.


Next - the wall is tightened with a diffuse membrane and sewn up with drywall or plywood

It should be noted that all sound and heat insulating materials made in mats or rolls are mounted on walls according to the same principle.

"Teksound" - a new direction in sound insulation technology

Texound is not yet as popular as mineral wool or polystyrene foam, as it is a relatively new sound insulator. by the most important advantage"texounda" in front of others soundproof materials is that it practically does not “steal” the useful area of ​​\u200b\u200bthe room, since it has a small thickness.


The main advantage of "Teksound" is the highest efficiency of sound insulation with a small thickness of the material itself.

This sound insulator is used for all surfaces of the room - it is fixed to the ceiling and walls, and also laid on the floor.

It should be noted that some craftsmen use "texound" in combination with thermal insulation materials, and such a bundle only increases the effectiveness of its use. But, unfortunately, the premises in apartments most often do not have extra space, which can be given over to a “powerful” multi-layered sound and heat-insulating structure. In this regard, a material was developed that is able to protect rooms from extra noise without reducing the size of the room.

To achieve desired effect and protect the room from outside sounds, it is necessary to cover all surfaces of the room with soundproofing material, otherwise it will not be possible to achieve the desired result.

The “texound” was developed in Spain by specialists from the well-known company TEXSA, and its mass production began there. industrial production. It is in this country that the largest deposit of the mineral aragonite, which is the main raw material, is located.

To be more precise, the base component is calcium carbonate (CaCO³). Aragonite is very rich in this compound. In addition, calcium carbonate is the main constituent of many calcareous rocks, including chalk, marble, and others.

Harmless polymer compounds are used as binding components, and as a result, high-density membranes are obtained, but at the same time very flexible and elastic, with pronounced viscoelastic qualities, which is extremely important for sound insulation of complex building structures.

Sound insulation of rooms with this material is very effective even if canvases with a very small thickness are used. "Teksound"Able to absorb and scatter even sound waves of high intensity, which come not only from the outside, but are also created inside the room, for example, with very loud music.


Texounda canvas covered with a protective film

"Teksound" is produced in canvases (membranes) and goes on sale in rolls packed in polyethylene. It has the following technical and operational characteristics:

Name of material parametersIndicators
Material density (kg/m³)1900
Average web weight (kg/m²)6.9
Area covered by one package (m²)6.1

Sound insulation coefficient Rw (average)28
Flammability (GOST 30244-94)G2
Elongation at break (%)300
Manufacturing materialsmineral aragonite, plasticizers, polyolefins, spunbond

In addition, the material has the following advantages:

  • "Texound" is resistant to temperature extremes. Its elasticity does not decrease at all even with negative temperatures up to — 20 °С .
  • The material has a pronounced flexibility and plasticity, and this "Teksound" is somewhat reminiscent of rubber.

"Texound" with its plasticity resembles dense rubber
  • The material is resistant to moisture and will never become a zone of mold or fungus, as it has antiseptic properties.
  • The operating time of the “texound” is not limited.
  • "Teksound" is perfectly combined with other materials, and can be applied in a complex system.

"Teksound"Subdivided by its thickness, size and shape of release, may have additional layers that improve its characteristics. The main brands are presented in the table:

Installation of "texound"

Almost any base is suitable for mounting this material - concrete, drywall, plastic, wood, metal and others. The main thing is that the surface is well prepared - leveled, cleaned of old coatings, primed and dried.

If there is a qualitatively applied layer of plaster on the wall, then it must be primed, and then installation can be carried out directly on it.

The work can be done in two ways. In the first of them, only soundproofing material is used, and in the second, it is used in combination with a heat insulator.

The first option - without additional insulation

  • Glue is applied to the prepared surface. For mounting " texound"A special mounting adhesive is used, which is sold in liquid form, ready for use, in canisters. After lubrication, it is necessary to wait 15÷20 minutes until the glue sets.

Marking and cutting canvases "Teksounda"
  • Further, the soundproofing material itself is mounted on the glued wall, which must be measured and cut off in advance, and also pre-lubricated with glue.

Special glue is applied both to the surface of the wall and to the Texounda canvas itself.
  • If self-adhesive material is purchased, then installation will be much easier, since it will not be needed for laying, and you will just need to remove the protective film and attach the material to the wall.
  • Next, the “texound” sheet must be pressed as tightly as possible to the surface, and then additionally walk over it with a roller. This must be done in order to achieve its best adhesion to the wall surface over the entire area, without leaving air bubbles.

Welding the Texound joints with a gas burner
  • Cloths "Teksounda"Be sure to overlap, by about 50 mm. The sheets are glued together hermetically. This process is carried out using "liquid nails" glue or by heating the material with hot air or gas burner- adjacent sheets are welded. If at least small gaps are left between the canvases during installation, then the effectiveness of sound insulation will be significantly reduced.

Fully texounded doorway
  • If the Texound installation is carried out on the ceiling, then it is glued in small sheets, since the material is quite heavy, and it will simply be impossible to hold a solid sheet from wall to wall.
  • After gluing the canvas, if necessary, it is additionally fixed on the wall with fasteners - "fungi", the very ones that are most often used for mounting polystyrene foam or mineral wool.

The second option - with the use of thermal insulation

Complex installation is carried out if the wall needs not only soundproof but also insulate. If there is such a task, then the work is carried out as follows:

  • On the primed wall along the edges, the crate frame is fixed.
Frame for "Texound" along the perimeter of the wall
  • The next step is to immediately glue Texound on the entire wall in one version, and in the other it is pre-laid heat-insulating material. However, the first method shows more high efficiency just for soundproofing.
  • If thermal insulation is adjacent to the wall, then "texound" is first fixed with "fungi", and then additionally pressed with metal hanger strips.

Fixing the "Texounda" canvases with "fungi" dowels
  • To achieve the required place for installing the insulation material, the metal profile of the frame is fixed in suspensions at a distance of 40 ÷ 50 mm from the wall. In this case, it is necessary to set each of the profiles according to building level, otherwise the casing of the frame will not be even.
Mounting metal frame over soundproofing sheets
  • The next step is the installation of insulation. The most environmentally friendly of suitable insulation materials that can be installed independently is basalt-based mineral wool. If financial funds, then you can use the above-described "Shumanet BM", which is not only noise absorbing but good thermal insulation material.
  • It fits tightly between the racks of the crate and is pressed against the Texound, mounted on the wall.
  • Upon completion of the installation of insulation, the wall should look like this:
  • It is advisable to tighten the heater vapor permeable diffuse membrane.
  • The next step is . In some cases plywood or OSB sheets are used for sheathing.
  • The sheets are fastened to the racks of the crate by self-tapping screws, the heads of which are recessed into the sheathing material by 1.5 ÷ 2 mm.
  • Then the joints and holes from the caps of the self-tapping screws are sealed with putty.
  • Further, the surface is primed and puttied completely, and after that you can decorate the walls with decorative material.

Drywall is the most comfortable material for alignment walls

The wall that received soundproofing and insulation protection, it is necessary to prepare for further work- to achieve a flat surface, which will become the basis for finishing materials. As well as - in special publications of our portal.

Existing schemes for mounting "texound"

Masters apply various schemes installation of this soundproofing device. Depending on the convenience of performing work, the area of ​​\u200b\u200bthe room and the required efficiency of wall insulation from external noise, you can choose any of them. The only drawback of these structures is their thickness, which even in the best case will be at least 50 mm.

First option

This design will have a thickness of 50 mm.


  • They begin to mount it with the fact that the prepared metal profiles from the side of their contact with the wall are pasted over with self-adhesive tape "Teksound S BAND 50". This must be done in order to avoid the transmission of sound and vibrations from the wall through the metal frame into the room.
  • Further, the frame elements are fixed to the wall with dowels, and heat-insulating, sound-absorbing mats are mounted between them.
  • Then, soundproofing material is glued onto the sheets of drywall, on their inner side. In this case, Texound 70 is well suited.
  • Thereafter. drywall is fixed on the racks of the frame, and its seams are sealed with putty.

Second option

The thickness of the structure with this option will be 60 mm.


  • In this case, a thin heat insulator is first fixed to the wall. You can use foil insulation by setting it with a reflective surface towards the room. The insulation should cover the joints of the wall with the floor and ceiling, that is, go to them by 150 ÷ ​​200 mm.
  • On top of it is made installation of a metal frame, which in the same way as in the first version of the design, it is attached to the wall.
  • Further, insulation mats are placed in the frame, which are covered with drywall with Texound 70 glued to it.

It should be noted here that the heat-insulating material attached to the wall can be replaced with "Teksound FT 75", which has an additional layer of felt.

Third option

The thickness of the third design option is 70 ÷ 80 mm, since it consists of more layers.


  • The first layer to the wall is installed heat-insulating material.
  • The second layer is the Texound sound-absorbing membrane.
  • A crate is mounted on top of it.
  • Then the insulation mats are installed.
  • Sandwich panels are fixed to the structure with the last layer, consisting of two sheets of drywall, between which Texound is laid.

When purchasing soundproofing material of this type, it is recommended to provide the consultant of the selling company with the characteristics of the material from which the house is built. The Sales Consultant will help you right choice by determining the thickness and better shape release of Texound.

Use of foam rubber mats as soundproofing

Acoustic foam can be called the most effective affordable material for soundproofing walls in an apartment. Due to its porous structure, this material perfectly absorbs and scatters sound vibrations.


Acoustic foam rubber is able to neutralize two types of noise - sound and vibration waves, that is, it muffles the sound and scatters low frequencies arising from surface vibrations, for example, knocking or "bass" of music.

The material is quite durable and can be mounted as an independent soundproofing material, and in combination with drywall. Foam mats are available in a wide range of sizes and can be embossed or have a flat surface.

Foam rubber is made by pressing polyurethane foam, after which cutting into standard blocks with a size of 1000 × 2000 mm is carried out. The thickness of the mats varies from 10 to 120 mm. Domestic material is produced in two or three colors, while imported options have a more diverse range of colors, including 10÷12 colors.

Material relief types

Types of relief pattern of acoustic foam can be different. Depends on the depth of the relief and overall thickness material, and his noise-absorbing properties.

The main types of reliefs used for the purpose of soundproofing rooms are presented in the tables below:

Material relief height (mm)25 50 70 100
"Wedge"
For moderate soundproofing of walls and ceilings.Effective for absorbing standing sound waves and echoes in medium to small rooms.For effective sound insulation rooms of any size.For absorption low frequencies, most often used in large halls.
"Pyramid"
For moderate wall protection against the penetration of high and medium frequencies.Standing wave protection small spaces. In combination with traps for low frequencies, they can completely soundproof the room.It is used for rooms of any size and is used in conjunction with additional soundproofing elements, such as sound traps.Same features as wedge material type

There are other, less frequently used acoustic foam elements.

Name of relief typeCharacteristics
"Peak"This relief of mats is less popular and has an unusual pattern. Its lack of demand is explained by lower soundproofing qualities than those of the materials mentioned above.
"Bass Trap"Waves that have a low frequency are harder to dampen because they are longer. For this, bass traps are installed in each corner of the room, which are designed for rooms of any size.
"Traps of high and medium frequencies"These elements are installed in large halls. They are designed to capture mid and high frequencies, and create the effect of scattering low frequencies. They are installed in a vertical position, but if the blocks are cut in two and placed at the corners, they will become traps for low frequencies.
"Corner Block"Corner blocks are made in the form of a triangular beam. They are installed at the corners of the room and at the junctions of two surfaces, and also serve to dissipate low frequencies.
Decorative ceiling tilesAvailable with and without embossed pattern. They are designed to change the relief and shape of the ceiling, with the help of which an additional soundproofing effect is achieved.
Insulating wedgesThey are used to reduce vibrations from studio equipment and are used as a substrate under it.

Until recently, acoustic foam rubber was rarely used in apartments, since the material tends to accumulate dust. But in last years more and more residents of panel houses choose foam rubber to reduce the sound transmission of walls. Due to its high sound-absorbing and scattering qualities, this material is able to make the room almost completely soundproof, provided that it is mounted not only on walls, but also on the surface of the ceiling and floor.

It is very important to note that acoustic foam rubber does not lose its soundproofing qualities at all when it is closed with drywall. The main condition for creating similar design is that the foam mats themselves must be glued directly to the wall base, without any lining.

Soundproofing acoustic foam walls

Installing foam rubber on the walls is not too complicated, so you can easily do it yourself. In this case, it is worth considering the most acceptable method of soundproofing for the conditions of the apartment, but it should be noted right away that the area of ​​​​the room will decrease somewhat.

Installation work is carried out in the following sequence:

  • In order for the foam rubber to stick easily, it is best to prime the wall surface and dry it well.
  • Next, the mats need to be fixed on the wall. They must fit snugly against its surface, otherwise the sound insulation effect will be partially lost.

  • Foam mats can be glued on a wide double-sided mounting tape, liquid nails or heated silicone.
  • When all the walls are covered with foam mats, you can proceed to the installation of the frame lathing from metal profiles or wooden beam. Frame guides are fixed at a distance of 50÷60 mm from the wall.
  • Racks are mounted in the recesses of the relief pattern directly to the wall. Mounting holes are drilled straight through the foam.
  • After fixing the frame of the crate, drywall sheets, plywood, PVC panels or other finishing materials are fixed on the rails. This will in no way reduce the efficiency of the sound absorption of the foam rubber layer, since it will be the first to receive all sound waves coming from outside, absorb them and scatter them.
  • In the same way, the foam rubber is mounted on a crate, and then one of the types of suspended ceilings is fixed on it.
  • Logs are laid on the floor over acoustic foam rubber, on which a plank or plywood floor is laid. Further, if desired, laminate, linoleum, carpet or other decorative coating can be laid on plywood.

It should be noted that the installation of acoustic mats does not require serious preparatory work. repair work, and if it is decided to leave the foam panels in open form, then their installation generally takes no more than one day.

Exposed material will require frequent cleaning with a powerful vacuum cleaner to keep a large amount of dust from accumulating inside this porous material. In the event that one of the panels for some reason has moved away from the wall, it can be quickly glued into place without any special preparations.

In addition to the considered soundproof materials, in the range construction stores others are presented. But today, acoustic foam rubber, texound membranes, shumanet plates and similar sound insulators can be called the most effective and safest for installation in an apartment.

A positive factor in modern construction is the use of new tools and technologies. Currently, some insulating materials have proven themselves well.

Overview of Thermo Reflect insulation

Thermo Reflect is a new generation construction tool. It is used to insulate ventilated roofs, floors, walls, attics and attics. Thermo Reflex consists of reflective multi-layer thermal insulation sheets. The layers of these sheets are polyethylene foam, polyester wadding or sheep's wool. The layers are separated from each other by metallized films of polyester material.

As a result of thermal radiation, overheating occurs in the premises in summer, and a significant part of the heat is lost in winter. With the help of Thermo Reflex insulation material, these transmissions are largely eliminated, since the principle of reflecting heat waves works. Thus, throughout the year, the comfort of housing is maintained.

In the construction of ventilated roofs of new buildings, as well as in the reconstruction of old ones, the use of insulating material helps to reflect heat radiation and protects against convection and heat loss. Thermo Reflex is used in the "underfloor heating" system. The aluminum contained in the material is an effective vapor barrier. If insulation is used for an unheated floor, a protective screen is created that prevents radon gas from entering the room.

The use of insulating material in attic spaces and attics prevents the transfer of heat from the roof. Thermo Reflex is fast and easy to install, no tiles or slates need to be removed, no plastering required. AT this case, a good finishing material will be plasterboard or wooden lining. In order to make better use of the reflectivity of the insulating material, when finishing work you need to leave a small air gap.

Insulation of the internal walls of the house along the perimeter provides maximum heat retention in the room in winter, maintains the optimum temperature in summer without the use of air conditioners. Spacer rails are mounted on the walls, on which Thermo Reflex sheets are fixed. Between themselves, the panels are connected with a special glue. The insulation material is fixed with drywall. In this case, air gaps of at least 2 cm are also left.

Such material is effective at any time of the year. It can be used to all bases and shapes. Thermo Reflex is waterproof, flame retardant, non-irritating and non-toxic. It has a small thickness, which almost does not affect the losses inner space residential premises. Thermo Reflex is durable in operation.

Another effective insulating agent in large scale construction is Tefond. This material is a polyethylene membrane having high density. Tefond reduces deformation pavement, reduces the thickness of the layers of the road "pie", reduces the mechanical effect on the base of the roads. This material is safe in operation, provides reliable protection, tightness and insulation of building objects.

Overview of Tefond insulation

Tefond can be mounted with vertical laying, with a waterproofing joint, according to a two-lock waterproofing system and according to a standard system. Tefond is the first insulating membrane that can be laid vertically during operation. According to this system, the material is fixed only in the upper part. Drilling holes in the walls is not used. Tefond can be used without horizontal joints on walls of any height.


A mechanical sealing system is used if Tefond is used for protection only. The end seal is sealed to make the seams watertight. Such a system is best defense from water and steam.

The material has a precise butt joint, thanks to which it is possible to obtain excellent sealing with a simple overlap of edges. Even if the membrane is subjected to high tension, there is practically no possibility of material rupture. Tefond is available in rolls standard sizes. Their height is 2.07 m. This reduces the cost of material when laying.


The insulating membrane is used to protect walls, foundations and roofs. This material covers surfaces in contact with the ground. Tefond is used in the construction of tunnels, automobile and railways, in hydraulic works. The use of insulating materials in construction is a requirement of today.

During construction or repair, walls, ceilings, floors and other surfaces are covered with special materials, to prevent heat leakage in the cold period and did not bother the heat in summer season. One of them is roll insulation, often used for large areas.

Advantages of roll material

This material has many advantages. The main thing is that the insulation in rolls does a good job of maintaining optimal temperatures indoors. There are other advantages:

The main types of insulation

Thermal insulation in twisted rolls can be used for both external and internal laying. There are options specially designed for pipes and communications. Rolled wall insulation is also available for sale directly under the wallpaper.

Raw materials for their production are also used differently. Thermal insulation from mineral components is the most common. Foamed polyethylene is also popular. Natural heaters like corks are less common and used. Some types have an additional layer in the form of foil or paper. Let's consider each option in more detail.

Special coating for thermal insulation

To improve the characteristics of their products, firms that produce rolled thermal insulation add certain coatings. The basis under them can be different.

Types of mineral wool in rolls

In this group of heaters there are several varieties. Their structure is the same, they differ in composition.

Any type of wool must be covered with a vapor barrier, especially in rooms with high humidity. And it also holds back the smallest particles of fibers that appear over time, negatively affecting a person. As part of the raw materials, formaldehydes are often used, which also affects health. Quality rolls should have a minimum of this substance

For laying mineral wool be sure to install the frame. On the walls, the panels with which it is held are pressed strongly so that the canvas does not move out over time. For the necessary protection from the cold, the number of layers can be increased.

Manufacturers often separate their product according to the purpose of the insulation. For ceilings and ceilings, the rolls will be lightened. For the main floor, walls, and other surfaces, the density of the material is usually increased. Due to this, the dimensions of the roll also change:

  • length from 3 to 8 meters;
  • thickness in 3 versions (50 mm, 100 mm, 150 mm);
  • width from 0.6 m to 1.22 m.

Insulating wool manufacturers

Hardware stores offer a wide selection of mineral wool. Consider the features of the materials of some companies specializing in this area:

Has many positive qualities. It is obtained by filling heated polyethylene with gases. As a result, a mass is formed with many closed bubbles inside, which subsequently solidifies. For special strength, it is also “crosslinked”, i.e., the bonds of molecules are strengthened by chemical means.

Therefore, there are for sale two options: stitched and, respectively, not stitched. Both types have very low thermal conductivity, but the first one still has the best performance, therefore it is more expensive (its density is 30 kg / m³). The general properties of materials are as follows:

The difference is that cross-linked polyethylene foam is able to absorb sounds well, but its fellow cannot boast of this. As a sound insulator, it works worse. Under mechanical action, the uncrosslinked version loses its shape irreversibly. The stitched one has a high compressive strength, which means it can be used for insulating horizontal surfaces.

Due to the thinness of the material, the length of the rolls can be up to 30 meters, the width is from 0.6 to 1.2 m. The thickness reaches 1 cm. . To fix the material on the wall, special glue is required.

Polyethylene foam brand Penofol

Insulation Penofol - appeared recently, but has already stood out among its own kind. It is not destroyed by weather conditions and aggressive environment. Heat insulators of this company have several varieties:

  • foil coating can be fixed on one or both sides;
  • rolls with an adhesive layer (simplifies installation even more);
  • specialized type of isolation for communication networks;
  • insulation for harsh conditions with a thickness of up to 40 mm.

Combined technology allows you to further reduce the thermal conductivity of insulated surfaces. Moisture-resistant and durable material that does not require vapor barrier costs can be used in various directions. Does not lose its properties in the temperature range from -60 to +100 С°.

Cork insulation for surfaces

An environmentally friendly and durable raw material for the production of thermal insulation is cork oak bark. Absolutely natural ingredients make rolls safe for health. The crushed bark is connected with organic glue and pressed. The thickness ranges from 2 to 6 millimeters. The length of the roll reaches 10 meters, the width is mostly meter. Most often, in this form, the cork goes under the wallpaper, on the substrate for the laminate or "warm floor".

Thermal conductivity index not inferior mineral wool, however, the layer used is much thinner. Cork insulation is slightly flammable, poorly absorbs water and delays noise. However, its density is high, respectively, and the weight is large. The margin of safety is high, the service life is declared up to 50 years. The negative side is the price of "naturalness", compared to the rest, it is quite high.

This insulation is produced mainly by Portuguese companies: Wicanders, Izora, Amorim. They propose a wide range of insulating rolls, which can simultaneously serve as wall decoration. Installation is also simple, basically the cork is “planted” on glue.

Modern technologies provide a huge selection of heat insulators for any premises and structures. The selection criteria are based on which surface needs to be covered and how much the buyer is willing to pay for it in order to maintain comfort in their home.
