Installation of basalt stone wool technonicol indoors. Technical characteristics of stone wool "TechnoNIKOL. Types and characteristics

Stone wool, one of the varieties of mineral wool, is perfect for warming the house and any room in it. With the help of our advice, you can choose the right material, make high-quality installation and take care of its long service life.

Stone wool: what is it made of

Cotton wool is made from rocks of basalt, marl or metamorphic origin. Basalt rocks are considered the best component. However, the quality will determine the acidity, which should be controlled by carbonate additions. The higher the acidity, the stronger and more durable cotton wool.

Stone wool insulation: what is it made of? Stone wool also contains a binder that holds the fibers together. The most famous substances are synthetic. They include phenol-formaldehyde resins and various impurities that make the material waterproof.

In modern production, stone insulation is made from a special component - "Pele's hair", or glass fiber. The stone wool technology for its manufacture consists of a number of stages, the main of which is the separation of the rock into fibers.

Characteristics and indicators of stone wool

The material has several important properties that are indispensable for repair or construction.

• Thermal insulation. Wall insulation with stone wool is a great way to protect yourself from the cold in winter and the heat in summer. The temperature in the room will be constantly regulated. The effectiveness of this property depends on the components in the composition. It turned out that stone wool for wall insulation is the right solution.
• Does not ignite. Even at temperatures above 1000˚C, stone wool does not ignite. Therefore, it belongs to safe materials, and, moreover, it protects other combustible parts of the house, preventing the spread of fire. Although the binders evaporate already at 200˚C.
• permanent form. Due to this characteristic, cotton can withstand mechanical stress. This allows you to use stone wool for floors that are constantly under load. Efficiency depends on the selected binder.
• Soundproofing. Provides simple protection from street or neighborhood noise as the fibers block sound propagation.
• Waterproof. Excess moisture in the room comes out without getting into the cotton wool. This property helps to maintain optimal humidity. And no matter how humid the air is, stone wool always remains dry, and mold and other muck do not start on it.
• Environmental friendliness. During production and operation, the environment is not affected negatively.

Pros and cons

Mineral wool for insulation has the following advantages:

• non-combustible;
• Waterproof;
• Stone wool - insulation for walls - has a wide range of operating temperatures;
• Eco-friendly;
• Safe during installation and operation;
• Good heat and sound insulation;
• It is easier to insulate with stone wool than with other materials.

Flaws:

• Wall insulation with wool is a costly undertaking. Don't expect to buy cheap cotton wool. Low prices for it indicate that it contains a lot of impurities and low-quality material.
• Dust. The process of insulating the walls of a house with stone wool is accompanied by an abundant amount of dust, especially if it is handled carelessly. For protection, it is advisable to take a respirator, although a regular mask from a pharmacy will do.

Stone wool: application

Wool insulation is used in the construction of baths, saunas, swimming pools, when laying communications, wells and air ducts. It is even placed in the foundations of houses.

Depending on where the insulation will be used, and what load it will have, it is divided into classes:

• Soft. Suitable for laying wells and ventilated walls.
• Semi-rigid. Suitable for walls in multi-storey buildings, for thermal insulation of pipes.
• Hard. Used in foundations, floors.

Is there any harm to health during installation?

Many inexperienced builders often confuse stone wool and glass wool, although in fact they are two different materials belonging to the same class of mineral wool. Because of this, a common myth has arisen that stone wool, like glass wool, is also harmful to health, damaging the eyes and lungs. But this is only a delusion.

The point here is its special structure. Insulation - stone fiber bound with formaldehyde resins, they do not break down and do not spread harmful substances. Therefore, we confidently declare that this building material is absolutely safe.

How to choose stone wool?

Before purchasing stone wool, you need to find out the amount of material you need and calculate the load that will fall on the insulation.

We have already said that the prices for it are high, but you can still save. The following factors will affect the cost:

• cotton wool density;
• Manufacturer;
• Binder and rock category;
• The presence of another layer of coating;
• Purchased quantity.

When buying, be sure to look at the instructions, it usually indicates the scope of stone wool and its technical characteristics. The most trusted companies are Ursa (URSA), TechnoNIKOL and Rockwool. The last company is located in Denmark; insulation materials from this country are of the highest quality, since strict certification bodies work there.

When choosing, check with the seller how the fibers are located: horizontally, vertically or in a chaotic manner. The first two types do not allow the material to deform, and the latter provides good heat and sound insulation.

Depending on the density, stone wool is usually divided into categories. Stone wool: wall slabs:

• Mark P-75. Suitable for horizontal, unstressed interior surfaces for pipe insulation.
• Insulation for walls cotton wool brand P-125. Suitable for both horizontal and vertical surfaces. It is ideal for insulating ceilings, floors and interior walls.
• PZh-175. Stone insulation for walls made of metal profiled sheet or reinforced concrete.
• Wool insulation PPZh-200. The hardest stone wool. This is used in buildings for engineering purposes, protecting them from fire.

Which mineral wool is better for wall insulation

Warming a house with stone wool begins with the choice of a manufacturer.

Stone wool "ROCKWOOL" - popular both in the domestic market and in the foreign. It has the following distinctive characteristics:

• Good level of strength;
• Mineral wool for wall insulation serves from 15 years;
• The fibers are arranged in a chaotic manner;
• Helps save electricity, as the manufacturer claims;
• An additional layer that increases resistance to moisture.

Stone wool "TechnoNIKOL".

• Produced only on the basis of basalt rocks;
• Extra layer for noise reduction;
• Light weight for easy work.

Wall insulation stone wool "URSA":

• Special packaging will make it easy to transport the material and work with it;
• Does not contain formaldehyde resins, therefore it is recommended for schools, hospitals, etc.

Buying a truly high-quality product can sometimes be difficult. Therefore, you need to know some important points.

• Pay attention to where and how cotton wool is stored. Most often, it is stored in its original packaging and wrapped in shrink film. Make sure there are no holes or cuts on the packaging. Cotton wool should not be in the open air, but under a canopy.
• If stone wool is packed in cardboard boxes (expensive heaters are usually placed in them), then its storage place must be protected from moisture. Even after a little getting wet, it will not be usable.
• Purchase goods only from trusted sellers. Give preference to those stores that are closer to you - this will reduce the cost of delivery.

Installation of stone wool

Before you properly insulate the wall with mineral wool, you need to determine where the work will be carried out. After all, the insulation of the walls of the house with cotton wool in each area will look different. On the facades, one technology is used, on the attics - a completely different one.

Balcony and loggia

The effective insulation of a house with stone wool directly depends on the quality of the surface preparation. Therefore, it is logical to talk about it briefly.

• Remove all excess debris from the loggia. Make the necessary measurements by calculating the amount of mineral wool. Estimate the load on the floor.
• Next comes the glazing of the balcony. Here it is better to give preference to plastic windows. All cracks on the frames and fencing should be sealed with mounting foam. This will greatly protect the balcony from moisture and cold.
• Waterproofing is the next step. Protective agents (roll or coating) must first be applied to the floor and ceiling. But wall protection is also desirable.

Only now you can proceed directly to laying. Insulation with mineral wool slabs occurs as follows:

1. First of all, the crate is made. It is most often made of wood (less often - of metal). The optimal thickness of the beam is 1 cm more than that of a stone wool slab. The dimensions of the cells in the lattice should be about a centimeter smaller than a piece of insulation.
2. Wool insulation for walls: laying goes from top to bottom: first the ceiling, then the walls and the floor. The ceiling needs a denser mineral wool, the usual one is suitable for walls and floors.
3. A special glue is applied to the plate, and it is placed in place in the cell. Before doing this, do not forget to clean the surface of dirt and remove irregularities.
4. You can press the slab firmly and evenly with plywood of a suitable size. Thermal insulation: stone wool is the best material for this.
5. The last step is vapor barrier using penofol (it is sometimes replaced with ordinary polyethylene).

Stone wool for attic walls

After you have installed the rafters and laid the roof on them, you can start warming the house with cotton wool. But first you need to create a layer of waterproofing. It will not allow water to get on the mineral wool and wooden structures. The best material for this is ordinary polyethylene. Fastening is carried out with a stapler.

If the waterproofing layer goes over the entire surface of the roof (up to the ridge), then it can only be insulated up to the attic ceiling. This is only done to save money. Quality repairs include insulation of the entire roof.

When laying stone wool, the most successful option is when the width of the beams on the roof is equal to the width of the slab. In this case, they simply fit between them, attached to the stapler. Additional reliability will be provided by a lath crate or a rope net laid from below. All gaps formed are sealed with mounting foam, and the crate (if it is made of wood) is treated with an antiseptic. Stone wool wall slabs insulate perfectly.

The last layer is the vapor barrier. As a suitable material, many builders choose glassine - it is cheap and performs its functions perfectly. It is attached to the rafters with a stapler, it is desirable to glue the attachment points with adhesive tape.

Insulation of walls from the outside with stone wool

In the process of insulating a house, the question often arises: is it better to insulate walls from the outside or from the inside? In the direction of each option, there are both disadvantages and positive aspects. The first option is like this:

• High protection against cold, noise, sun and wind;
• Will not let the walls freeze, because. moisture is released. For the same reason, mold and fungus do not form on the structures;
• The area of ​​the room inside will not decrease;
• It becomes possible to choose any internal design, as well as, if necessary, change it.

Convinced of the merits of this method, we insulate the stone walls of the house. The traditional way of laying looks uncomplicated: the first insulating layer is medium-density mineral wool (75 kg / m³), ​​it closes the unevenness of the wall; the second layer is high-density wool (from 125 kg/m³), its role is to create a smooth and rigid wall surface, because this will facilitate the next finishing work.

In total, wool for wall insulation from the outside should be a layer of 15 cm or more. The best option is when the thermal insulation is located between the load-bearing wall and the outer cladding.

In practice, it is possible to insulate a house with stone wool from the outside according to the following plan.

1. The first step is to prepare the surface. Rid the walls of irregularities, and apply a layer of plaster. Sometimes it makes sense to apply a couple of layers.
2. Next comes the installation of metal guides, they are fixed above the basement of the building using anchor bolts.
3. How to properly insulate a wall with mineral wool? The first layer of heat-insulating material is installed (immediately followed by the second). Glue is applied to the back of the plate, and it is pressed against the wall. According to the same scheme, all external wall insulation with stone wool takes place.
4. Metal corners that are attached to external slopes will help protect the material from deformation.
5. A facing brick is placed on top of the layer, the seams are sealed with plaster.

We considered the first installation method, called a ventilated facade. You can insulate the walls with stone wool in the second way.

The second method is called "wet". The technology is only slightly different from the previous one. Stone wool: wall insulation:

Both of these methods insulate the house equally well.

After you have insulated the walls with stone wool from the outside, you need to take care of some important things.

The thermal insulation layer will increase the thickness of the walls by about 15-20 cm. Therefore, it is advisable to lengthen the slopes, ebbs and window sills so that the weather conditions do not spoil the material.

If you decide to lay not two layers of mineral wool, but more, then this is a bad idea. The more layers, the more air pockets between them. And they lead to a deterioration in thermal insulation properties.

Wall insulation from the inside with stone wool

Warming with stone wool from the inside is much faster and cheaper, and even novice builders can easily cope with this matter. However, work can only be done in a room where there is no high humidity. The advantages of wall insulation from the inside are as follows:

• Low cost and labor intensity.
• You can put insulation not only on the entire building, but also on individual rooms in which you will live. This is quite economical.
• It is permissible to work at any time of the year, regardless of weather conditions.

Insulation of the house with mineral wool can be started by calculating the required amount of mineral wool. There is a special formula for this. Wall area (m²) multiplied by the mineral wool thickness (mm) and divided by the package volume. That is, if the area is 15, the thickness is 100, the volume is 0.432, then you will need about three and a half packages.

Do-it-yourself wall insulation with stone wool is carried out in several stages. The general scheme of an insulated wall may look something like this: first there is a load-bearing wall, followed by a layer of vapor barrier, then thermal insulation, and another vapor barrier layer, at the end there is an interior finish.

Stone wool for interior walls is suitable for medium density (look for indicators in the region of 100 kg / m³). Such mineral wool will increase the thickness of the wall by 8-10 cm. Keep this in mind when carrying out repairs. It is possible to insulate a small room with mineral wool in one day.

One of the methods for fulfilling the above plan occurs according to a relatively simple technology. Stone wool: installation:

1. A strong support is created from metal suspensions and profiles. Under it, you can put a foam-based tape to improve the thermal insulation in the room. If you plan to create two layers of mineral wool, then you will need another additional frame.
2. Then comes the vapor barrier. If polyethylene was chosen as the material, then a small air chamber should be left between the wall. It can be attached either with adhesive tape or with glue.
3. Stone wool insulation is placed inside each section in the frame.
4. Then again comes the layer of vapor barrier. This time it is better to fasten it directly to the metal profile with self-tapping screws.
5. Drywall is laid on top and the interior is finished.

Stone wool of internal walls, as well as wool of external ones, perfectly protects against unnecessary noise. This is especially useful in those houses that are located near roads.

Foundation insulation

Usually baths need insulation of the foundation, so we will first talk about them. Why is it necessary to insulate the foundation?

• Due to the difference in temperature inside and outside, condensation forms, spoiling the base of the bath. The heater also helps to cope with this problem.
• Thermal insulation will reduce the amount of wood needed for kindling.
• Stone wool can protect against some mechanical damage.

It is better to insulate with mineral wool on the outside of the plinth, because in this way the foundation will be better protected, and therefore will last longer. The installation technology shown below is suitable for a strip foundation. Warming with mineral wool:

1. Free the foundation from the earth. To do this, dig a trench with a depth of one and a half meters and a width of 50 cm.
2. After that, sand is laid, and the foundation is smeared with bitumen.
3. Then the heater is installed. Its thickness is at least 20 cm. Seal the formed seams with foam. At the corners of the bath, a layer of mineral wool is 1.5 thick. Working with stone wool is easy here.
4. Stone wool needs additional protection from a brick wall (thickness - from 25 cm), which is placed around the perimeter. At the top there will be a blind area.

A few rules and notes for quality work.

How to choose and apply glue on mineral wool

Without proper selection and use of glue, insulation can sag, ceasing to act effectively. Stone wool is a rather unusual material, and not every adhesive is capable of providing high-quality adhesion to the wall.

The highest adhesion will provide polymer-cement compositions. They are sold as a dry mix similar to cement. There are several well-known brands: "EK THERMEX", "ERESIT CT190", "ERESIT CT180".

Using the package directions, dilute the mixture with water and mix well (repeat the same after 5 minutes). The solution will retain its adhesive properties for 2 hours.

Apply the solution evenly on a flat surface of the wall so that 7-8 glue circles are obtained. On the back side of the cotton wool (closer to the edges) we also apply glue; the surface should be covered with the composition by more than half. It is also better to grease the joints. The glue hardens for some time, so it is possible to properly lay the slab. Attaching stone wool to a wall is easy.

Sometimes, for greater reliability, additional fastening may be required. Anchor bolts or slats fixed to the crate can help here.

Stone wool is one of the most popular heaters from the mineral wool category. For manufacturing, gabbro-basalt rocks are used, and the resulting product has found active use in the field of construction. Used to obtain a high-quality heat and sound insulating layer. In the modern construction market, TechnoNIKOL basalt wool is considered the most common.

Compound

In the production of insulation, specialists use rocks, or rather gabbro-basalt raw materials. Thus, the resulting heat insulator is not affected by fire. The fibers can only melt smoothly when affected by a temperature of 1000 degrees. Due to this property, TechnoNIKOL mineral wool began to be used as a protection for the house from destruction and deformation during a fire.

Detailed description

Before you buy TechnoNIKOL stone wool, you need to familiarize yourself with its technical characteristics in more detail.

Coefficient of thermal conductivity

This stone criterion may vary depending on the type of material. Be within 0.034 to 0.047 W/m*S. Thus, it becomes clear that 10 cm of insulation are able to store thermal energy as well as 38 cm of timber or 140 cm of brick.

On the photo-thermal conductivity of technonicol stone wool:

The process of insulation with TechnoNIKOL wool is carried out in 1-2 layers.

Plate Density

This characteristic of the material is determined by the coefficient of thermal conductivity. If we consider the Rocklight and Technolight material, then its density is 30-40 kg / m3, but the Technoflor material, which is used to insulate the floor under the screed, this figure is 81-185 kg / m3.

Degree of vapor permeability

This characteristic is also one of the main ones. The lighter the material, the better its vapor permeability. Therefore, the microclimate in the house will be comfortable for living.

In addition, insulation with high vapor permeability has a longer service life. This is due to the fact that water molecules do not retain steam on their surface for a long time. Since TechnoNIKOL cotton wool is 99% air, they pass steam perfectly. The degree of permeability of the material will be 0.3−0.6 mg/(m.h.Pa).

Degree of water absorption and refractory properties

Since specialists used various additives in the manufacture of TechnoNIKOL stone wool, the resulting material can perfectly retain moisture. The level of water absorption of the heat insulator will be 1-2%.

Since TechnoNIKOL mineral plates are a non-combustible material, it is advisable to use them for thermal insulation in those houses where there is a high risk of fire. TechnoNIKOL plates are not amenable to combustion, and the melting process occurs only at a temperature of 1000 degrees.

If a fire occurs, then the TechnoNIKOL stone wool will be able to delay the spread of the flame for some time. Moreover, it protects against fire and other materials that are less resistant to fire. But what is the thermal conductivity of mineral wool and how is it determined. help you understand the information in this

On the video - the technical characteristics of TechnoNIKOL stone wool:

Life time

The service life of TechnoNIKOL mineral wool is quite long even under adverse conditions. The minimum service life is 50 years. This result is achieved due to the fact that the material has excellent characteristics. Basalt fibers do not rot or corrode. In addition, they are not afraid of rodents. But to increase the service life of the material is possible only if it is properly mounted. So during installation, you must definitely take care of the hydro and vapor barrier.

But what is the difference between basalt wool and mineral wool and what is better to choose for your construction site, the video from this article will help you understand:

Varieties

It will also be interesting to learn about what it is. For those who want to know more about the exact materials, it is worth reading the contents of the article.

Mineral wool insulation in the family of thermal insulation materials owns the lion's share of 80%. At the same time, obtained from rocks such as dolomite, basalt or diabase, it is of high quality, harmless and long service life. The fibrous structure formed from molten drops is mainly used in critical structures, which are subject to increased reliability requirements. Flexible and versatile material, which is buy stone wool can be used for insulation of any building structures, communication systems, for suspended facades and other objects, the surface temperature of which does not exceed + 700°C.

Basic properties

Compared to other similar products, the insulation has a number of characteristic features, including:

1. Fire resistance maintained throughout the entire service life. The maximum temperature at which the material retains its properties reaches +1000°C. In many buildings, insulation is used as passive fire protection, which is especially important when insulating boilers, fireplaces, and stoves. The material has been assigned the flammability category NG.
2. The level of noise absorption.
3. The coefficient of thermal conductivity indicates thermal resistance and depends on the thickness of the layer. For comparison, a 10-cm sample with a density of 100 kg / m3 is taken, which should have the same properties as a sand-lime brick with a size of 200 cm, clay - 117 cm, and a wooden block with a thickness of 25.5 cm. Its value varies between 00.034 W / m * K, 034 and slightly inferior to those of fiberglass.
4. Vapor permeability determines the level of humidity in a building.
5. The service life of high-quality insulation should be at least 40-50 years.
6. The amount of shrinkage is responsible for the formation of "cold bridges" and the smaller it is, the greater the likelihood of maintaining the geometric parameters of the material.
7. Resistance to destructive microorganisms.
8. Easy to install. Soft samples can be cut with a knife, and dense ones are cut with a saw.

Expert advice:

If the insulation layer is subjected to vibration or constant vertical loads, then the sediment will be significant. If stone wool is bought loose, then over time it can clump, turn into dust, and its installation will be very expensive.

The range includes various stone wool price which depends on many nuances, but mainly on the level of quality and branding.

The right choice of heater

In the ranking of stone wool manufacturers, the leadership belongs to the Danish company ROCKWOOL (service life - 35 years), the Finnish manufacturer Paroc and the domestic company TechnoNikol. The top three are followed by the products of URSA (30 years), KNAUF (35 years) and ISOVER (40 years).

PAROC UNS soft insulation samples have a thermal conductivity of 0.039 W/m*K. They are recommended for use on objects that are not subjected to mechanical stress, for example, in the construction of frames, wall insulation, the construction of cardboard partitions, and more.

PAROC FAS boards have found application in wet plastering systems. Modified heaters, known as FAL-1, FAB-3, which have high bending strength and are indispensable when installed on curved surfaces. The FAB-3 material, only 30 mm thick, fits perfectly into door and window openings.

Stone wool is selected depending on the application, for example:

• for a sloping roof, the density of the material should be 30-40 kg / m3, the best option is PAROC insulation (PAROK);
• samples with a parameter of 50 kg / m3 are selected as a heater for walls;
• external walls are protected by a 10 cm layer. Wool density index PAROC WAS 25t; equal to 80 kg/m3;
• for residential attics and for flooring, it is recommended to buy 15 cm PAROC EXTRA products with an indicator of 40 kg / m3;
• Finnish stone wool price which is in perfect proportion with its quality.

As for the domestic products of TechnoNikol, made from raw materials of the gabbro-basalt group, in its family There are several types of heaters, in particular:

• Technolight boards are designed for unloaded structures;
• technofas is an indispensable component of plaster systems;
• technovent is used for ventilated structures;
• technoroof is recommended for insulating mastic or rolled roofs.

The presence of water-repellent elements in Techno products gives cotton wool a water-repellent ability, which allows it to be used in pools, baths, etc.

Rockwool and Knauf insulation (+500°C) is recognized as the best stone wool, capable of withstanding high operating temperatures, followed by Ursa (+400°C) and Izover (+300°C) closes the list. At the same time, all materials, except for Ursa wool (+850 ° C), retain their structure and shape when heated above + 1000 ° C. All products are represented by mats and plates, and Knauf and Rockwool additionally produce insulation in the form of cylinders. The most affordable material is Izover and Ursa, and the highest cost is for expensive and high-quality Rockwool material.

Stone wool is one of the varieties of mineral wool. It is produced from gabbro-basalt rocks and is widely used mainly in construction. It is used in the construction of buildings and structures as a heat and sometimes sound insulator. One of the most common brands of basalt wool in the domestic market is TechnoNIKOL.

This material has earned its popularity due to its not too high cost and unique technical characteristics.

How is it made

In the production of TechnoNIKOL mineral wool, the rock is preliminarily loaded into melting furnaces and heated to a temperature of 1400-1500 gr. Further, the molten stone mass is poured into a special centrifuge.

Here, tops rotating at a speed of up to 7000 revolutions per minute break it into small fibers. During this procedure binders are poured into the centrifuge. At the next stage, the fibers already impregnated with phenol-formaldehyde resin enter the lamella machine and are formed into a carpet of a given thickness.

The domestic company of the same name, founded at the end of the last century, manufactures mineral wool of the TechnoNIKOL brand. At the moment it includes more than 20 enterprises and 120 outlets operating throughout the country. The mineral wool of this manufacturer is made from high-quality materials using modern equipment, and therefore is very popular not only in Russia, but also abroad.

Scope of application

Mineral wool of this manufacturer is used, like any other, most often for insulation of enclosing structures of buildings: walls or roofs. It is also used to insulate doors, pipelines, attic and attic floors, etc.

The main advantage of mineral wool in comparison with another popular insulation today, polystyrene foam, is incombustibility. Therefore, it can also be used to isolate chimneys when passing them through ceilings and roofs.

Some disadvantage of this material is its hydrophilicity. Stone wool absorbs moisture very well. However plates brand "TechnoNIKOL" in this regard, they are considered quite reliable and of high quality. During the production process, they are impregnated with special hydrophobic compounds, which significantly increases their resistance to moisture at times.

Varieties of cotton wool "TechnoNIKOL"

Today, this company produces several types of basalt wool, designed for different purposes. So, for example, for roof insulation, the option can be used "Technoruf", and for the facade - "Technofas". For soundproofing doors, ceilings, etc., Technoacoustic wool is used. The most popular type of plates from this manufacturer is TechnoNIKOL Rocklight - a universal material with moisture-resistant additives, which can be used for insulation or soundproofing of almost any structure.

Specifications

When buying a heater of this type, usually pay attention to its properties such as:

Basically, the characteristics of cotton wool of all TechnoNIKOL lines are similar. Differences exist only in such parameters as density and thermal conductivity. For example, varieties used for floor insulation are usually rigid and able to withstand heavy loads (the weight of a concrete screed). Softer materials are more often used to isolate facades and roofs. but with good resilience. After all, they are installed without fasteners at a distance between the elements of the frame. Very dense cotton wool is also used under the plaster. But for wrapping pipes, soft flexible cotton wool "TechnoNIKOL" is usually used.

Coefficient of thermal conductivity

This indicator for TechnoNIKOL stone wool, depending on the variety, can range from 0.034 to 0.047 W / m * C. That is, 10 cm of this material are able to save warmth is as good as 38 cm timber or 140 cm brick. Warming of structures with TechnoNIKOL wool is usually done in 1-2 layers. Walls and roofs in central Russia are most often insulated with 10 cm thick slabs. For floors along logs and pipes, 50 mm material is usually used in two layers.

Plate Density

Not only the coefficient of thermal conductivity, but also the price of it largely depends on this characteristic of wool. The fact is that more rigid slabs of the same thickness of basalt fiber take more. For TechnoNIKOL stone wool, the density, as already mentioned, can vary greatly depending on the purpose of a particular line. So, the universal "Rocklight" and "Technolight", used to insulate structures that are not subjected to loads, have a density of 30-40 kg / m3. For plates of the Technoflor line, used for floor insulation under a screed, it can reach 81-185 kg / m3.

Material cost

The price of dense materials of this brand is approximately 3000-4000 rubles. This is quite a lot, but such plates are usually used in small quantities. The price of TechnoNIKOL light materials varies only in the range of 500-800 r per 1 m³.

Degree of vapor permeability

This is also a very important characteristic of mineral wool. The easier the slabs allow vapor to pass through, the better the microclimate will be in the rooms insulated by them. Besides, material with a high degree of vapor permeability And he usually lasts longer. Indeed, in this case, water molecules do not linger on its surface for a long time.

Since TechnoNIKOL cotton wool is 95-99% air, they are able to pass steam very well. The degree of permeability of the plates of this brand is 0.3−0.6 mg/(m.h.Pa). For comparison: for even the best manufacturers of expanded polystyrene, this figure is only 0.015–0.019 mg / (m.h.Pa).
