The construction industry offers many various types thermal insulation materials. Despite their diversity, they can be divided into several main types. The most used materials for thermal insulation:

• mineral wool insulation;
• expanded polystyrene and its extruded modification;
• foamed polyethylene with metallized coating;
• polyurethane foam.

Each of the listed insulation options has its own strengths and weaknesses and optimal area of ​​application.

Properties of mineral wool insulation

Mineral wool is a modern modification of glass wool and does not have many of the disadvantages of the latter. It is made from waste from the metallurgical industry with the addition of processed basalt rocks. Available in the form of mats and rolls of various sizes.

The disadvantages of mineral wool insulation include significant specific gravity, gradual subsidence under the influence of its own gravity and “dusting” during installation.

These thermal insulation materials have the following advantages:

• high thermal insulation ability;
• good noise absorption;
• fire resistance;
• low cost.

Widely used for insulation of floors, walls, roofs, attics and basements. Used as a heat insulator for ventilated facade systems.

Expanded polystyrene - insulation characteristics

Is a foamed polymer material with high thermal insulation characteristics. It is used, like basalt insulation, when processing all structural elements of the house.

Positive differences:

• light weight;
• high sound insulation;
• good vapor barrier and compression resistance;
• resistance to moisture, chemical and biological factors;
• ease of installation.

Disadvantages: fragility, low fire resistance and the ability to release toxic compounds upon fire.

There is an extruded analogue of PPS on sale, which has better characteristics in terms of density, ductility and moisture resistance. Extruded polystyrene foam – modern insulation ny material. It is more durable and stable, easy to process, but its cost is higher than conventional foam. The areas of application of both varieties are similar.

Modern heat insulator consisting of foamed polyethylene and aluminum foil. There are many varieties available, varying in thickness, availability self-adhesive film and the number of reflective layers (there may be one or two).

Advantages of insulation:

• Small thickness with high thermal insulation ability. A sheet of penofol corresponds to the efficiency of a mineral wool board, which is 20 times thicker than it.
• Good vapor barrier;
• Protects from external influences of moisture and wind;
• Versatility. Thanks to the reflective ability of the foil, it protects against all types of heat loss: convection, thermal conductivity and radiation;
• Ecological cleanliness;
• Easy to cut and install.

It is successfully used wherever materials for thermal insulation are in demand: in construction, industry, automotive, and defense. In the residential sector it is used as insulation of any elements of buildings, water supply and sewerage pipelines, ventilation and air conditioning systems. Indispensable as a reflector installed between the heating radiator and the wall.

Polyurethane foam for thermal insulation

A progressive insulation method consisting of spraying liquid composition onto the insulated surface. The hardened and expanded polymer creates reliable protection from the cold. Thermal insulation materials such as polyethylene foam and polyurethane foam are the most effective technical solutions.

The advantages of PPU include:

• low thermal conductivity;
• seamless technology that does not form cold bridges;
• good adhesion to most building materials;
• accessibility of the most difficult places;
• anti-corrosion properties;
• resistance to moisture, fungi and mold;
• noise protection properties;
• durability.

The weak point is the instability to direct action sun rays. This can be prevented by painting or using polyurethane foam as a heat insulator in curtain facades. Therefore, polyurethane foam is used everywhere where the materials listed above are used.

Polyurethane foam is applied using sophisticated equipment operating under high pressure, and using expensive components. Only qualified specialists can carry out this work. This explains the high cost of this method.

The technologies presented above are not all options for insulating residential buildings. There are other materials for thermal insulation: expanded clay, insulating plaster, foam rubber, perlite, insulation made from recycled hemp and flax, non-woven insulating fiber, foam glass and others. They account for less than 5% of the total volume of heat insulators used. The main types of materials used were discussed above.

Thermal insulation materials are products for construction that have a low level of thermal conductivity. They are intended for insulation of buildings, technical insulation and protection of cold chambers from heating.

To decide on the choice of material for thermal insulation, you need to know its properties and characteristics. It is important that the material has low thermal conductivity. The latter is ensured by the movement of molecules that transfer heat. Thermal insulation materials help slow down their movement.

Important properties of insulation materials

Thermal insulators are called building materials with a low thermal conductivity coefficient. If thermal insulation is used to retain heat internally in a building, the materials are called insulation.

Materials for thermal insulation must have a number of properties:

• low thermal conductivity;
• porous structure;
• density;
• vapor permeability;
• water absorption;
• biosustainability;
• fire resistance;
• fire safety;
• temperature stability;
• heat capacity;
• frost resistance.

Common types of insulation

There are quite a few varieties of materials for thermal insulation, one of them is insulation with a fibrous structure, which includes mineral wool. It has high porosity, approximately 95% of its volume is air. That is why mineral wool has good thermal insulation properties and is often used to insulate buildings. Its production is quite affordable, and therefore the price too. The advantages of mineral wool include:

• does not retain moisture;
• does not burn;
• provides sound insulation;
• long service life.

It is worth noting that when moisture gets on the material, it loses its thermal insulation properties. When installing mineral wool, it is necessary to use a hydro- and vapor barrier film.

Glass wool is made from fibers that are obtained from quartz sand, soda, and lime. Materials for thermal insulation can be purchased in the form of a roll, plate or shell. According to its characteristics, it resembles mineral wool, but is a little stronger and dampens noise to a greater extent. The disadvantage is the low level of temperature stability.

Foam glass is made by sintering gas-forming agents with glass powder; it is produced in the form of slabs or blocks. Its structure has a porosity of up to 95%, which provides excellent thermal insulation properties. Foam glass is a fairly durable material for thermal insulation, with the following characteristics:

• frost resistance;
• water resistance;
• incombustibility;
• strength;
• long service life.

Disadvantages - high price and vapor tightness

Cellulose wool is a wood fiber material with a fine-grained structure, which consists of 80% wood fibers, 12% fire retardant and the remaining 8% antiseptic. Thermal insulation material is laid using two methods: dry and wet. For the wet laying method, a special installation is used, with which wet cellulose wadding is blown out. Thus, the adhesive properties of pectin are activated. The dry method can be done manually or using special equipment. Cellulose wool is poured in and compacted to a certain density. Cotton wool is quite affordable and has good insulating properties.

Materials for thermal insulation are quite varied, so it is necessary to study the properties in order to make a choice. After all, each building requires a certain material.

The choice of thermal insulation material is a responsible process. Today, many manufacturers have begun to produce insulation that can perform several functions at once. It not only makes the surface warm, but also creates reliable protection against wind, moisture, steam and corrosion.

Species

If you decide to insulate the walls, then when you go to a hardware store, you will see that the assortment outside is quite wide. Each of the available insulation materials differs not only in its thermal insulation qualities. Let's look at the main ones.

Liquid materials

Several years ago, builders actively used solid thermal insulation materials to insulate walls. But not so long ago, new ones with a liquid consistency began to appear on the construction market. In appearance and consistency, such products are similar to paint, which is why they are often called insulating paint.

In the photo - liquid thermal insulation materials for walls

The composition of liquid thermal insulation is presented in the form of small capsules made of ceramics and glass. They are filled with air or inert gas. The role of the binding component is performed by acrylic polymers. The finished product is a thick dough.

Hard materials

To insulate walls, rigid insulation materials can be used, the installation of which is much simpler. They are geometrically correct slabs, thanks to which you can obtain a perfectly flat surface. Then simply plaster or veneer it various materials. For the most part they fit like .

The photo shows rigid thermal insulation materials for walls:

Solid insulation does not shrink or wrinkle. Installation of solid insulation does not require lathing, frames or other structures. The materials are highly durable and their service life is more than 50 years.

Warm plaster

Among the advantages of this material are high strength indicators. This suggests that the surface is very difficult to damage, which cannot be said about previous materials. Warm plaster is a liquid heat insulator. This is nothing more than a cement-sand mortar with the addition of natural and polymer fillers.

In the photo- warm plaster

Thanks to them, it is possible to reduce the thermal conductivity of the original composition. The thermal conductivity of walls with a heat insulator will directly depend on the fillers used. When laying out a thin layer 1-1.5 cm thick, you can replace 50 ml of polystyrene foam. But you can understand what warm plaster for the facade looks like and how it is used by looking at the photos and information

Gas-filled plastics

This material for thermal insulation of walls is considered one of the most effective. To obtain it, the method of foaming various materials is used. The result of this process is a sheet foam insulator.

Photo-gas-filled plastics

Its installation is simple and convenient. Expanded polystyrene can easily be considered one of the leaders among all produced foam plastics. You can use a heat insulator to insulate walls from the outside. But what they are and where exactly it is used is described in this article.

Liquid foam

This is another option for liquid insulation. Its name is penoizol. Its filling is carried out using hoses between the walls, in the cracks, and in the formwork at the time of construction. This insulation option is a budget option, since its cost is 2 times cheaper compared to other analogues.

The photo shows liquid foam for walls

Liquid foam is able to resist microbes, is breathable, does not burn well, and has a long service life. But what kind of liquid thermal insulation for walls from the inside exists, in addition to the above, is described in this

Extruded polystyrene foam

Polystyrene granules are used to make this material. They are melted under high temperature. The material is then extruded from the extruder and foamed. This is what gives such .

Photo-extruded polystyrene foam for walls

Thus, it is possible to obtain strong, durable and breathable insulation. He communicates well with various coatings walls

Glass wool

This material is a type of mineral fiber. Glass scrap is used to make it. Glass wool is produced in different densities and thicknesses. If you need thin fiberglass, then you need to choose a material with a thickness of 5 cm. This is enough to replace a meter-long brick wall.

In the photo there is glass wool for the wall

Fiberglass has high fire resistance and elasticity. Characterized by excellent performance heat and sound insulation. But when installing fiberglass, you need to take care of your safety by wearing a respirator.

Election criteria

When choosing a thermal insulation material for insulating external and interior walls, a number of requirements must be taken into account:

1. Thermal insulation performance. The higher this indicator, the better material will retain heat.
2. Weight. The lighter the heat insulator, the fewer difficulties arise during its installation.
3. Vapor permeability. If this indicator is high, then excess liquid will drain freely.
4. Flammability. In this case, the indicators can determine how fire hazardous the material is and whether it poses a threat to the house and its occupants.
5. Eco-holic purity. When purchasing modern insulation, you can be sure that it consists exclusively of natural raw materials.
6. Service life. It is necessary to select insulation that has a long service life, so as not to waste extra effort and money on repeated work.
7. Price. And although the price of a heat insulator is indicated as the last criterion, for many it is the most important. Of course, you must understand what more expensive material, the higher it is technical specifications.

When working with walls, it is useful to know the difference.

Thermal insulation of walls is a responsible job that requires the choice of high-quality insulation. Today there are enough options on the construction market, each of which has its own technical characteristics and is suitable for insulating walls outside or inside the house.

Heat loss, especially in winter, negatively affects the health of apartment residents. 30% of the heat escapes through cracks in windows and doorways, and 20% is lost through the floors, mainly on the ground floor, where the heated room is in contact with the ground, if there is no thermal insulation layer. Floor insulation makes your life more comfortable: you can walk on the floor barefoot at any time without fear of catching a cold. The heat in the apartment is maintained thanks to the thermal insulation of the floor. The question arises: “Which floor insulation should you choose?”

Today we will tell you about what types of floor insulation exist, what are their advantages and disadvantages. We will introduce you to the criteria for choosing a thermal insulation layer, tell you which insulation is best for retaining heat in the house, and how to install it correctly in a particular room.

Criteria for choosing floor insulation

To choose the right material for floor insulation, you should pay attention to the following criteria.

The insulation must be:

Types of floor insulation

To choose the right thermal insulation material, you need to know what types the industry offers and what their advantages and disadvantages are.

There are several types of insulation:

• mineral;
• polymer;
• wood-chip.

Expanded clay

Expanded clay is baked clay in granules.

Despite its advantages, there are also minor disadvantages.

Expanded clay takes a long time to dry and slowly releases absorbed moisture. Expanded clay produces dust, so you need to wear a respirator when working with it.

Otherwise, expanded clay is a convenient and high-quality insulation material. Expanded clay is used to insulate walls, floors, and roofs of houses.

Polymer house insulation

These include:

1. expanded polystyrene foam;
2. polyurethane foam;
3. foamed polyethylene on a foil base;
4. penoizol-liquid foam.

Expanded polystyrene

One of the polymer floor insulation materials is polystyrene foam. This is a foamed plastic mass. Consists of individual granular cells.

• This is a durable material that, despite its light weight, can withstand high loads.
• Due to its low weight, polystyrene foam itself creates minimal load on the walls and foundation.
• It is moisture resistant, so it can be used in places with high humidity on the balcony.
• Polystyrene foam retains heat for a long time, almost without absorbing it. It surpasses many insulation materials in terms of thermal insulation.
• When insulating floors, you can get by with a small thickness of polystyrene foam.
• The price of expanded polystyrene is low, which is an important advantage of this material and attracts the attention of buyers.

An important disadvantage of polystyrene foam is that when burned it emits harmful substances which are poisonous and dangerous.

Extruded polystyrene foam

Extruded polystyrene foam differs from polystyrene foam in its manufacturing method and characteristics. Polystyrene foam is obtained by exposing the granules to steam. At high temperature the cells increase in size and fill the entire form. A foam element is added to extruded polystyrene foam when high blood pressure and temperature, which is extruded through the extruder.

The thermal insulation properties of extruded polystyrene are much better than conventional polystyrene foam. But extruded polystyrene foam has lower vapor permeability. Another disadvantage is high flammability.

Foamed polyethylene on a foil base

Foamed polyethylene on a foil base is one of the best floor insulation materials. It is obtained by melting polyethylene in a special container with the addition of liquefied gas, which acts as a foamed reagent. A foil film is applied to one side of the polyethylene foam, which reflects heat. Foil-coated polyethylene is supplied in rolls, sheets, and slabs.

• The closedness of the cells contributes to high hygroscopicity. The waterproofness of the material allows you to insulate floors and walls in baths and saunas.
• The material is resilient and elastic, durable: it can withstand significant loads and does not deform.
• Caustic acids, alkalis, gasoline and other petroleum products do not affect polyethylene.
• Laying foil polyethylene is easy and simple by hand, because it weighs little and is quite thin. Foil insulation is designed in such a way that it reflects heat back into the room. It does not transfer heat to the external environment. Therefore, it should be laid with the reflective side up.

Penoizol

Penoizol-liquid foam.

It is good because it is poured into all the cracks and hard-to-reach places.

Insulation is especially necessary when building a house, because it fills all the air voids and thereby retains heat.

Polyurethane foam

Polyurethane foam is one of the best floor insulation materials of our time.

Wood-based insulation materials include:

• plywood;
• cellulose wadding;
• sawdust.

Ecowool

Ecowool is a loose material made from cellulose. It is filled automatically or manually, covering the most inaccessible places. The cotton wool is poured into special pumps, and it passes into the room through thick pipes. Ecowool is not liquid.

The disadvantage of ecowool is its fear of moisture, so it is not recommended to use this material in rooms with excessive humidity.

Sawdust materials

Sawdust itself is not used for insulation because it does not meet fire safety requirements. Mainly used for insulation:

1. sawdust pellets;
2. wood concrete;
3. wood blocks.

Wood blocks are sawdust with the addition of copper sulfate and cement.

Sawdust granules are obtained by adding antiseptics to them, making them resistant to the appearance of microorganisms. Sawdust granules have low thermal conductivity and high sound insulation properties.

Arbolit-wood concrete. It is fire resistant. Possesses increased strength, can quickly restore its shape after excessive loads. Absorbs sound waves perfectly and retains heat.

Its disadvantage is low moisture resistance. If you want to make insulation from wood concrete, then the humidity in the apartment should not exceed 75%. A finishing protective layer should be laid on top of the wood concrete.

One of the popular insulation materials is cork. This is the best insulation for linoleum, but also the most expensive. Cork fiber is obtained by processing oak wood. The wood is crushed, the particles are glued together with suberin, which is part of oak. They are steamed and pressed to form cork fiber. The material is completely natural and does not contain any polymer additives. The material is durable, moisture-resistant, lightweight. Due to its structure (consists of cells, each of which is filled with a gaseous substance) it is considered the best heat insulator.

Cork fiber can be used as a substrate and as an independent floor covering.

How to lay insulation on the floor

Different insulation materials need to be installed differently.

Mineral wool is laid between the joists. But the glass wool should be properly insulated so that when it wears out, dust does not get into the apartment. It is very important to leave a ventilation gap.

Laying ecowool

Ecowool is laid mechanically or manually. Small particles of ecowool pass through the hose, and the operator uses air to direct the material with glue added to it onto the wall or floor. Sticking. Ecowool particles create a thermal insulation layer. Cotton wool is applied to the floors manually, both liquid and dry. It just falls asleep between the lags. Placed on top vapor barrier membrane, and then wooden floors. The price of ecowool insulation along with work is 2200 per cubic meter using the dry method and 2800 per cubic meter using the wet method.

Laying expanded clay

There are 3 options for laying insulation such as expanded clay:

First you need to sweep the floor, clean construction waste. Need to make a bed PVC film or a special vapor barrier layer. Mark the level of the screed. Then apply 10cm wide edge tape to leave a gap from the walls. Fill the floor with expanded clay, level it with a rule, and fill it with screed on top. You can separate the screed with a waterproofing layer;

Laying foam

Expanded polystyrene is laid and then filled with cement or concrete. This is a floating screed.

Logs are placed under wooden floors, and foam plastic is laid between them.

The third way to lay polystyrene foam is to lay it on a concrete floor, and on top of them are sheets of plywood.

Polyurethane foam application technology

First you need to prepare the base: remove debris. Unevenness of the base does not matter when laying polyurethane foam. The main thing is that there are no oil stains on the surface, otherwise there will be no reliable adhesion of the insulation to the base in this place. You should pay attention to the humidity of the floor; it should not exceed 5%. The air temperature must be maintained at least +10 degrees. Polyurethane foam is applied through a special nozzle. Components A and B are mixed and sprayed. The material must be evenly distributed using special equipment over the surface of the base. The specialist himself regulates the thickness of the polyurethane foam layer. The insulation dries within 24-48 hours. If the insulation is placed between wooden joists, then after the material has dried, installation can be done finishing coating. If polyurethane foam is placed on concrete base, then you need to pour a cement-sand screed on top of it, which will protect the heat-insulating layer.

Today we told you about floor insulation. We revealed the advantages of each of them and reported on the features of their installation. And which one is better is up to you to choose. We hope you do right choice.

Soundproofing walls in an apartment modern materials for which today can be found in construction stores, is becoming increasingly relevant. This can be explained simply - fences in multi-storey buildings standard houses are not able to completely 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, preventing him from getting 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 basic principles as traditional ones. However, they have undergone significant improvements due to recent production technologies.

Today, a very large number of new soundproofing materials are being produced, and it is simply impossible to cover the characteristics of all of them in one article. Therefore, attention will be focused on the most effective ones, which are used specifically in apartment conditions.

Thin sound insulation 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 waste precious centimeters of living space?

In this case, the innovative thin soundproofing material MaxForte SoundPRO is suitable for you. It has a thickness of only 12 mm, while its characteristics can compete with sound insulation with a thickness of 5 and even 10 cm! MaxForte SoundPRO — newest material, created specifically for soundproofing residential and industrial premises.

Specialists from the Research Institute of Building Physics and the Department of Acoustics, Faculty of Physics, Moscow State University, took part in the development of the material. When manufacturing MaxForte SoundPRO, we took into account all important points for the effective operation of the material: the optimal density was selected (if the density is low, the sound will pass through, if the density is too high, along the “skeleton”), the length of the fibers, and 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 or any adhesives. Therefore, in addition to excellent noise insulation properties, MaxForte SoundPRO is safe for health.

MaxForte SoundPRO provides an increase in noise insulation from both airborne noise (loud TV, crying child, screaming neighbors) and impact noise(noise from stomping, grinding furniture, falling objects). It can be used to soundproof ceilings, walls and floors, which will give a significant increase of up to 64 dB!

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

MaxForte SoundPRO is mounted on the wall using ordinary plastic mushroom dowels, which can be purchased at any hardware store. It is hung on the wall using the “joint-to-joint” technology, after which it is covered with a layer of gypsum fiber board (gypsum fiber sheet). All sheet seams must be sealed with a special vibroacoustic non-hardening sealant. Afterwards, the sound insulation is sewn up with a layer of gypsum plasterboard (plasterboard sheet). The seams of the gypsum fiber board and gypsum board sheets should be staggered, that is, not coincide.

You can see the installation of thin sound insulation MaxForte SoundPRO in the video.

Thin wall soundproofing panelsSoundGuard EcoZvukoIzol

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

SoundGuard EcoZvukoIzol panels are made of durable multi-layer cardboard profiles 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, and for example brick wall or a steel door is much worse). In addition to its weight, quartz sand, due to its fine fraction, perfectly dampens and absorbs almost all frequencies of sound - from airborne to shock.

How to install panelsSoundGuard EcoZvukoIzol?

Installation of the panels is very simple and almost anyone can handle it. are attached to the wall using SoundGuard DAP acoustic anchors, which are driven into pre-drilled holes through the panel in the wall. After this, all seams and joints are coated with sealant and the entire wall is covered with plasterboard.

Mineral sound-absorbing material "Shumanet-BM"

This soundproofing The material, made from basalt fibers, is considered a premium mineral sound-absorbing board. One side of the mat is laminated with a layer of fiberglass, which helps maintain the integrity of the slab and hold 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 with perforated acoustic panels.

Packaging of soundproofing boards “Shumanet”

Plates " Schumanet BM" are manufactured in accordance with the requirements of SNiP 23 — 03-2003 “Noise protection”. They have the following technical and operational characteristics:

	Indicators
Standard slab size (mm)	1000×500 or 1000×600
Slab thickness (mm)	50
Material density (kg/m³)	45
Number of slabs per package (pcs.)	4
Area of ​​slabs in one package (m²)	2.0 or 2.4
Weight of one package (kg)	4.2÷5.5
Packaging volume (m³)	0.1 ÷ 0.12
Sound absorption coefficient (average)	0.95
Flammability (GOST 30244-94)	NG (non-flammable)
Water absorption when partially immersed in water for 24 hours, % of total volume	No 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 Russian Academy architecture and building sciences.

The basis of “Shumanet” is 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 from plasterboard, plywood, fiberboard and other sheet materials.

Soundproofing walls using Schumanet BM

Installation of the slabs of this sound insulator follows 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 additional insulation.

The work is carried out in the following sequence:

• On the prepared surface, markings are made to secure the sheathing elements. Since the width of the mats is 500 mm, and they must stand apart between the bars, 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.
• Next, the sheathing elements themselves are fixed, but at the same time, so as not to weaken the basic qualities of the soundproofing material, experienced craftsmen advise to perform a series simple recommendations:

— For lathing, it is best to use wooden beams rather than metal profiles, since metal is good guide sound, can resonate, and wood tends to dampen sound waves.

— Additionally, in order not to create bridges for the passage of sound, it is recommended to make gaskets from thin sound-proofing material, for example, felt or strips, between the wall and the sheathing bars basalt wool 8 ÷ 10 mm thick.

— If, after all, a metal profile is chosen for the sheathing, then it is better to move it away from the wall with a soundproofing pad by 12 ÷ 15 mm.

- In the case that the area soundproof the room is large enough, and it is possible to move the sheathing for sound-absorbing material and cladding 100 mm from the wall, then special ones can be used to fasten the bars 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 that effectively dampens vibrations without transferring them to the frame guides.

Special suspension used for soundproofing work

If guide bars secured in the manner indicated above, then the soundproofing mats are mounted in two layers. The first of them is installed behind the sheathing elements, close to the wall, and the second is installed between the guides.

Double-layer placement of “Shumanet” panels

• Ultimately, upon completion of installation of the Schumanet BM panels, the walls should look like this:

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

Next, the wall is covered with a diffuse membrane and covered with plasterboard 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.

"Texound" - a new direction in sound insulation technology

"Texound" is not yet as popular as mineral wool or expanded polystyrene, since it is a relatively new sound insulator. The most important advantage of the Texound over others soundproofing materials is that it practically does not “steal” the usable area of ​​the room, since it is small in thickness.

The main advantage of Texound 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 combination only increases the effectiveness of its use. But, unfortunately, the rooms in apartments most often do not have extra space that can be given over to a “powerful” multi-layer sound and heat insulating structure. In this regard, a material was developed that is able to protect rooms from excess noise without reducing the room in size.

To achieve the 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 be impossible to achieve the desired result.

Texaund 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 basic component is calcium carbonate (CaCO³). Aragonite is very rich in this compound. In addition, calcium carbonate is the main component of many calcareous rocks, including chalk, marble and others.

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

Soundproofing rooms with this material is very effective even if canvases of very small thickness are used. “Texound” is capable of absorbing and scattering even high-intensity sound waves that come not only from the outside, but are also created indoors, for example, during very loud music.

Texaunda canvas covered with protective film

“Texound” is produced in sheets (membranes) and goes on sale in rolls packaged in polyethylene. It has the following technical and operational characteristics:

Name of material parameters	Indicators
Material density (kg/m³)	1900
Average specific weight of the canvas (kg/m²)	6.9
Area covered by one package (m²)	6.1
Weight of one package (kg)	42
Sound insulation coefficient Rw (average)	28
Flammability (GOST 30244-94)	G2
Elongation at break (%)	300
Manufacturing materials	mineral aragonite, plasticizers, polyolefins, spunbond

In addition, the material has the following advantages:

• "Texaund" is resistant to temperature changes. Its elasticity does not decrease at all even at negative temperatures down to - 20 ° C .
• The material has pronounced flexibility and ductility, and in this way “Texound” is somewhat reminiscent of rubber.

"Texound" with its plasticity resembles dense rubber

• The material is resistant to moisture and will never become an area for mold or mildew to spread, as it has antiseptic properties.
• The operating time of the Texound is not limited.
• Texound combines well with other materials and can be used in a complex system.

“Texound” is divided according to its thickness, size and release form, and may have additional layers that improve its characteristics. The main brands are presented in the table:

Name	Sound insulator release form	Linear parameters of the material, mm

Installation of "texound"

Almost any base is suitable for installation of this material - concrete, plasterboard, 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 high-quality 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 carried out 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. To install the texound, a special assembly adhesive, which is sold in ready-to-use liquid form in canisters. After coating, you must wait 15-20 minutes until the glue sets.

Marking and cutting of Texound canvases

• Next, the soundproofing material itself is mounted on the glued wall, which must be measured and cut in advance, and also pre-coated with glue.

Special glue is applied both to the surface of the wall and to the Texound canvas itself.

• If you purchase self-adhesive material, then installation will be much easier, since adhesive will not be needed, and you will just need to remove protective film and attach the material to the wall.
• Next, the texaund sheet needs to be pressed as tightly as possible to the surface, and then additionally walked over it with a roller. This must be done to achieve better adhesion to the wall surface over the entire area, without leaving air bubbles.

Welding Texound joints using a gas torch

• Texound canvases must be overlapped by approximately 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 during installation even small gaps are left between the panels, the effectiveness of sound insulation will be significantly reduced.

Doorway completely finished with Texound

• If Texound is installed 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 single sheet from wall to wall.
• After gluing the canvas, if necessary, it is additionally fixed to the wall with fastenings - “fungi”, the same ones that are most often used for installing polystyrene foam or mineral wool.

The second option is using 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:

• The sheathing frame is attached to the primed wall along the edges.

Texound frame around the perimeter of the wall

• The next step is to immediately glue Texound onto the entire wall in one version, and in the other, heat-insulating material is pre-laid. However, the first method shows more high efficiency specifically for sound insulation.
• If thermal insulation is adjacent to the wall, the “texaund” is first secured with “fungi”, and then additionally pressed with strips of metal hangers.

Fixing Texound panels with mushroom dowels

• To achieve the required space for installing the insulating material, the metal profile of the frame is fixed into hangers at a distance of 40÷50 mm from the wall. In this case, it is necessary to set each of the profiles according to construction level, otherwise the frame skin will not be smooth.

Installation metal frame on top of soundproofing sheets

• The next stage is the installation of insulation. The most environmentally safe of suitable insulation materials that can be installed independently is considered to be basalt-based mineral wool. If financial allow funds, then you can use the above-described “Shumanet BM”, which is not only sound-absorbing, but a good thermal insulation material.

• It fits tightly between the sheathing posts 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 insulation vapor permeable diffuse membrane.
• The next stage is . In some cases Plywood or OSB sheets are used for cladding.
• The sheets are fastened to the sheathing posts using 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 screw heads are sealed with putty.
• Next, the surface is primed and puttied completely, and after that you can decorate the walls with decorative material.

Drywall is the most convenient material for leveling walls

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

Existing texound installation schemes

Craftsmen use various installation schemes for this sound insulator. Depending on the ease of performing the work, the area of ​​the room and the required efficiency of insulating the walls from external noise, you can choose any of them. The only disadvantage of these structures is their thickness, which even in the most best case scenario will be at least 50 mm.

First option

This design will have a thickness of 50 mm.

• They begin to install it by covering the prepared metal profiles on the side of their contact with the wall with self-adhesive tape “Texound 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.
• Next, 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 to the plasterboard sheets on the inside. In this case, Texound 70 is suitable.
• After that. drywall is fixed to the frame posts, and its seams are sealed with putty.

Second option

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

• In this case, first a thin heat insulator is attached to the wall. You can use foil insulation, installing it with the reflective surface towards the room. The insulation should cover the joints of the wall with the floor and ceiling, that is, extend to them by 150÷200 mm.
• On top of it is produced installation of a metal frame, which just like in the first design option, it is attached to the wall.
• Next, insulation mats are laid into the frame, which are covered with plasterboard with Texound 70 glued to it.

It should be noted here that the thermal insulation material attached to the wall can be replaced with Texound 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 of thermal insulation material is installed on the wall.
• The second layer is the Texound sound-absorbing membrane.
• A sheathing is mounted on top of it.
• Then the insulation mats are installed.
• The last layer on the structure is sandwich panels, consisting of two sheets of plasterboard, 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 make the right choice by determining the thickness and better shape release of Texound.

Using foam mats as sound insulation

The most effective affordable material for soundproofing walls in an apartment can be called acoustic foam rubber. Due to its porous structure, this material perfectly absorbs and dissipates sound vibrations.

Acoustic foam rubber is capable of neutralizing two types of noise - sound and vibration waves, that is, it muffles sound and dissipates low frequencies arising from vibrations of surfaces, for example, knocking or “bass” of music.

The material is quite durable and can be installed as a stand-alone soundproofing material, and in combination with drywall. Foam mats are available in a wide range of sizes and can be textured or have a flat surface.

Foam rubber is made by pressing polyurethane foam, after which it is cut into standard blocks measuring 1000 × 2000 mm. The thickness of the mats varies from 10 to 120 mm. Domestic material is available in two or three colors, while imported options have a more varied range color scheme, including 10÷12 colors.

Types of material relief

The types of relief patterns of acoustic foam rubber can be different. Both the total thickness of the material and its sound-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 sound insulation of walls and ceilings.	Effective for absorbing standing sound waves and echoes in medium to small rooms.	For effective soundproofing of rooms of any size.	To absorb low frequencies, most often used in large halls.
"Pyramid"
	For moderate protection of walls against penetration of high and medium frequencies.	Protection against standing waves in small spaces. In combination with traps for low frequencies, they can completely soundproof a room.	It is used for rooms of any size and is used in conjunction with additional soundproofing elements, such as sound traps.	Same characteristics as wedge material type

There are other, less commonly used elements made of acoustic foam.

Name of relief type	Characteristics
"Peak"	This mat relief 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"	Low-frequency waves are more difficult to dampen because they are longer. For this purpose, bass traps are installed in each corner of the room, which are designed for rooms of any size.
"Treble and Mid Frequency Traps"	These elements are installed in large halls. They are designed to capture mid and high frequencies, and create a low frequency diffusion effect. They are installed in a vertical position, but if the blocks are cut in half and installed at the corners, they will become low frequency traps.
"Corner block"	Corner blocks are produced in the form of a triangular beam. They are installed in the corners of the room and at the junctions of two surfaces, and also serve to dissipate low frequencies.
Decorative ceiling tiles	They are produced with or without a relief pattern. They are designed to change the relief and shape of the ceiling, thereby achieving an additional soundproofing effect.
Insulating wedges	Used to reduce vibrations from studio equipment and used as a substrate for it.

Until recently, acoustic foam rubber was rarely used in apartments, since the material tends to accumulate dust. But in recent years More and more residents of panel houses are choosing foam rubber to reduce the sound conductivity of the walls. Thanks to its high sound-absorbing and dissipating qualities, this material can make a room almost completely soundproof, provided it is installed 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 any of its soundproofing qualities when it is covered with plasterboard. The main condition in creating such a structure is that the foam mats themselves must be glued directly to the base of the wall, without any lining.

Soundproofing walls with acoustic foam

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

Installation work is carried out in the following sequence:

• To make the foam stick easily, it is best to prime the wall surface and dry it well.
• Next, the mats need to be fixed to the wall. They must fit tightly to its surface, otherwise the sound insulation effect will be partially lost.

• You can glue foam mats using 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 frame sheathing made of metal profiles or wooden beams. The frame guides are mounted at a distance of 50÷60 mm from the wall.
• The racks are mounted in the recesses of the relief pattern directly to the wall. Holes for fastenings are drilled directly through the foam.
• After fixing the frame of the sheathing, sheets of plasterboard, plywood, PVC panels or other finishing materials are fixed to the guides. This will not in any way reduce the sound absorption efficiency of the foam layer, since it will be the first to receive all sound waves coming from outside, absorb them and dissipate them.
• In the same way, the foam rubber is mounted on the lathing. The lathing is installed directly on it, and then one of the types of suspended ceilings is fixed.
• On the floor, logs are laid on top of acoustic foam rubber, on which a plank or plywood floor is laid. Further, if desired, laminate, linoleum, carpeting or other decorative covering can be laid on the plywood.

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

The exposed material will require frequent cleaning with a powerful vacuum cleaner to prevent large amounts of dust from accumulating within the porous material. If one of the panels comes away from the wall for some reason, it can be quickly and without special preparation glued into place.

In addition to the considered soundproofing materials, the range includes construction stores others are presented. But today, acoustic foam rubber, Texaund membranes, Schumanet slabs and similar sound insulators can be called the most effective and safe 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 to be excellent.

Thermo Reflex insulation overview

Thermo Reflex is a new generation construction product. 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 fabrics are polyethylene foam, polyester wadding or sheep's wool. The layers are separated from each other by metallized films made of polyester material.

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

When constructing ventilated roofs of new buildings, as well as when reconstructing old ones, the use of insulating material helps to reflect heat radiation and protects against convection and heat loss. Thermo Reflex is used in a heated floor system. The aluminum contained in the material is an effective vapor barrier. If insulation is used for a non-heated floor, it creates protective screen, which prevents the penetration of radon gas into the room.

Application of insulating material in attic spaces and attics prevents heat transfer from the roof. Thermo Reflex is installed quickly and easily, no need to remove tiles or slates, no installation required plastering works. IN in this case, good finishing material will be plasterboard slabs or wooden lining. To make better use of the reflectivity of the insulating material, when finishing works 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 and maintains optimal temperature without using air conditioners. Spacer strips are mounted on the walls, onto which Thermo Reflex sheets are fixed. The panels are connected to each other using special glue. The insulating material is secured with plasterboard. In this case, air gaps of at least 2 cm are also left.

This material is effective at any time of the year. It can be used on all bases and shapes. Thermo Reflex is waterproof, flame retardant, non-irritant and non-toxic. It has a small thickness, which almost does not affect losses internal space living space. Thermo Reflex is durable in use.

Another effective insulation product for large-scale construction is Tefond. This material is a high-density polyethylene membrane. Tefond reduces the deformation of the road surface, reduces the thickness of the layers of the road “pie”, and reduces the mechanical effect on the road base. This material is safe to use, provides reliable protection, tightness and insulation of construction sites.

Tefond insulation review

Tefond can be installed with vertical installation, with a waterproofing joint, with a two-lock waterproofing system and with a standard system. Tefond is the first insulating membrane that can be installed vertically during operation. According to this system, the material is fixed only in the upper part. Drilling holes in walls is not allowed. 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, making the seams watertight. This system is the best protection against water and steam.

The material has a precise joining point, thanks to which it is possible to obtain excellent sealing by simply overlapping the edges. Even if the membrane is subjected to strong tension, there is virtually no possibility of the material rupturing. Tefond is available in rolls standard sizes. Their height is 2.07 m. This reduces material costs during installation.

Insulation 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, roads and railways, and in hydraulic work. The use of insulating materials in construction is a requirement of today.
