When choosing heaters, most developers are looking for an option that combines the maximum of useful properties. It is important to maintain a favorable microclimate in the house, ensure the removal of vapors, prevent the accumulation of condensate, and protect residents from toxic synthetic substances. Traditionally, mineral wool is famous for such properties. german Knauf company supplies the market with a wide range of insulation products designed specifically for different conditions operation.
The manufacturer manufactures slab and roll insulation from fiberglass material obtained using the advanced Knauf Ecose technology from natural raw materials: basalt, sand and resins of natural origin. The finished product has all the necessary qualities:
1. Heat saving. The coefficient of thermal conductivity is quite low (0.037-0.04 W / m2), which allows you to maintain a comfortable temperature in the house.
2. Manufacturability. Elastic fiberglass adheres to the elements of the building without air gaps, it is resistant to vibration and shrinkage, does not delaminate.
3.Low weight. Lightweight Knauf slabs and mats load the supporting structure of the building less, they are easier to install.
4. Ease of transportation and storage. High elasticity makes it possible to compress the insulation during transportation and storage - while they take up little space. After delivery, the material straightens out, completely restoring its shape and size. Reliable packaging film allows you to store heaters manufactured by Knauf outdoors under any conditions.
5. Noise isolation. According to reviews, insulation allows you to ensure silence in the house, even if there is a busy highway next to it
6. Fire safety of a heater. Knauf fiberglass mineral wool is not flammable.
7. Vapor permeability. Water vapor passes through the insulator without interference, providing optimal humidity parameters for the building and structures.
8. Chemical and biological resistance. Glass wool is odorless, does not rot, prevents the development of mold, does not enter into chemical reactions. Fiberglass is too tough for rats and mice.
9. Environmental friendliness. The basis is natural materials, and the technology of their processing does without formaldehyde and acrylic components, bleaches and dyes. During operation, during heating, during a fire, no harmful substances are emitted from cotton wool.
Despite many positive properties, Knauf insulation has a number of disadvantages that should be considered at the selection stage:
1. Danger to skin, eyes and respiratory tract. During mechanical processing of glass wool fine particles of glass dust are released. It is necessary to protect hands, organs of vision and breathing with gloves, goggles and a respirator. To prevent fiber particles from entering the room, this layer is securely covered with other materials.
2. Moisture permeability. After installation of the insulation plate, they need reliable hydroprotection, otherwise they quickly lose their qualities.
To improve moisture resistance, the company has developed a special Aquastatik technology.
Overview and description of thermal insulation properties
It is mounted on the walls and roofs of private housing constructions and high-rise buildings. Divided into several groups:
1. Insulation TeploKNAUF - a product line for private houses. This group includes roll and plate universal insulators, which are mounted on walls, roofs, internal partitions, floors. They are divided into three subgroups:
- "Dacha" - recommended for seasonal residences. Their coefficient K = 0.044 W / m2, sheet thickness - 50 mm. During installation, the mechanical load limits must be observed;
- "House" - used for year-round houses, they transmit less heat (K = 0.040). There are types with a thickness of 50 and 100 mm;
- "Cottage" - provide a higher level of protection against cold (K = 0.037), noise and moisture. Thickness - 50 and 100 mm.
All of them have the same density - 11 kg / m3. They differ in linear dimensions, which allows narrowing the intended use of a particular type Knauf products.
2. Knauf Insulation - a group of facade, roof and wall insulators designed for professional insulation of residential and industrial buildings.
What is Knauf Insulation? These are rolled or plate materials of increased rigidity, tightly fitting both vertical and inclined bases.
Depending on the purpose of application, they are divided into several types:
2.1. Facade heaters. This group includes three brands of Knauf plates: 032A (K = 0.032), 034A (K = 0.034) and 037A (K
= 0.037), with a density of 25-34 kg/m3. They are produced with a thickness of 50 and 100 mm, their linear dimensions are 610x1250 mm. They are used for insulation of ventilated facades (in 1-2 layers), as a middle layer of insulation in houses with brick cladding and in sandwich panels, mounted under siding. Materials undergo moisture protection treatment, almost do not crumble and have a long service life.
2.2. Roof. The HEATROOM series from Knauf has indicators K = 0.034, 0.037 W / m3, a density of 15 kg / m3 and high moisture resistance. The series is suitable for timber framed roofs, floors attic floor on logs, ceilings. The dimensions of the plates are the same as those of the previous type.
2.3. Universal heaters: Thermo Roll Knauf Insulation and the slab option HEATPLATE 037. The roll is laid on attic floors, attic and interfloor floors, floors on logs above basements, attached to external and internal walls and to a pitched roof. Feature of rolled Knauf: it is not too dense (11 kg / m3); with a width of 1200 mm there are several lengths (from 6 to 12.5 m).
Knauf HEAT Slab 037 (50x610x1250, 100x610x1250) with a density of 15 kg / m3 is recommended for pitched roofs, ceilings, walls of frame houses, partitions.
The price of thermal insulation Knauf
The average cost of a cubic meter of insulation in Moscow and the Moscow region:
As can be seen from the table, you can buy Knauf Insulation at a price that is much lower than the cost of Penoplex (from 3,500 rubles / m3) and Izomin (2,100 rubles / m3).
Reviews and opinions about Knauf products
“I have experience installing Knauf Cottage (50 mm). There is practically no dust: compared to ordinary mineral wool, hands do not itch - just super. One drawback: it does not hold its shape well - soft, like a blanket. When installing the top sheet, you do not feel whether it rests on the bottom sheet or there is a gap. But still, I will insulate the attic only with Knauf, so that there are no harmful substances, and it serves for a long time - at least 40 years.
Alexander Stelmakh, Moscow.
“Dacha” glass wool was chosen after reading the Knauf product catalog first. This roll insulation light, I cut it with an ordinary paint knife, however, I worked with gloves (prickly). The main thing is that mineral wool does not burn - I have a wooden dacha. The tree under this material breathes, the vapors pass through the insulation, and then there is an air gap, waterproofing and siding - such a “layer cake” does not let the cold through. The house is warm but not stuffy. The walls can also be insulated from the inside, profiles can be installed and then sheathed with drywall.
Oleg Stankevich, Samara.
"I built frame extension Knauf HEAT Slab 50 mm was laid to the log house and on the walls. The attic was insulated between the rafters with a pitched roof in two layers (100 and 50 mm), and the walls of the first floor were insulated with Knauf Cottage slabs 100 mm. When laying, there were no problems - the material between the bars keeps perfectly. After installation, the walls were tightened with waterproofing and finishing work was carried out. Now about thermal insulation: in winter, even in the most severe frosts in the house, the temperature did not fall below 21 °, and in the annex it was +18. The only negative: the roof is made of metal, the rain rattles on it - I am unhappy with the Knauf soundproofing.
Sergey, Yekaterinburg.
“To insulate the floor in the house, I decided to lay TEPLORolon 040 and did not regret it. The cost of insulation in Knauf Insulation rolls is advantageous in that you can choose packaging by square - from 15 to 30 m2. I bought a 6-meter roll - fewer joints are obtained. The mat is flexible, adheres well to the surface, it is a pleasure to work with it. In general, Knauf is a very well-known company - you don’t need to worry about harmful fumes, if only you don’t run into a fake. The floor turned out to be warm - even in the corridor you can walk barefoot.
Under the Knauf brand, not only excellent finishing materials are produced, but also good heaters made of mineral wool, fiberglass and polystyrene. The choice is truly royal, but it is not easy to understand the numerous series and areas of their application. To decide which thermal insulation and where it is better to use, we advise you to familiarize yourself with the description of the main lines from Knauf, their pros and cons.
Our review should begin with the division of all German brand products into two large families of mineral wool (Insulation and TeploKnauf) and the Therm polystyrene board line. In each of them there are interesting options that differ from each other in terms of performance.
Product lines
1. TeploKnauf (glass wool).
- Knauf Dacha.
A budget series of heaters with rather weak insulating properties - 0.044 W / m∙K. The manufacturer honestly recommends this modification only for country houses periodic residence. In winter, judging by the reviews, Dacha as a heater is really ineffective. Therefore, it is better to buy it not for housing, but to use it in auxiliary buildings like a garage.
- Knauf House and House Plus.
Plates with a thickness of 5 and 10 cm are used for insulation of city apartments and private houses. Conductivity indicators are quite common for glass wool - 0.04 W / m∙K, all other properties are also quite average. However, buyers often leave negative reviews about this heater. The main claims: non-compliance with the declared characteristics and poor acoustics.
- Knauf Cottage.
Universal insulation that can be used to insulate walls and roofs country house(read how to choose a roofing insulation). Due to the water-repellent impregnation, the boards are characterized by good resistance to moisture, but this does not mean that they can be left without the protection of special films. But the heat-saving characteristics are among the best in this line (0.037 W / m∙K). The slabs have a classic thickness of 50 mm and 100 mm in Knauf Cottage +.
Despite some differences in terms of insulating properties, all insulation options Heat Knauf have the same density of 11 kg/m3. This is a very low figure, which limits the scope of their application. Judging by the reviews, it is undesirable to use them in vertical and simply loaded structures. But in the roofing pie and between the lags of the floor, Knauf works well as a heater.
2. Knauf Insulation.
The line is positioned as a professional thermal insulation of high rigidity. It is represented by rolled and plate materials made of glass wool:
- For walls.
Plates of Teplo Stena-032A, 034A and 037A brands weighing from 25 to 34 kg / m3 are used in ventilated facade systems, as well as for insulation of double structures made of bricks or building blocks. Separately, you can purchase a modification of Teplo Slab-037 for frame buildings. Not so long ago, Knauf introduced an elastic novelty - Acoustic glass wool in the form of plates. However, according to residents, the effect of its use in ceilings and internal walls is felt with a layer of at least 100 mm.
- Roof insulation.
Insulation Heat Roofing is characterized by low specific weight (only 15 kg/m3) and increased moisture resistance. In addition to the roof slopes, slabs can sheathe the walls of the attic and even the floor, if it rests on the logs. Also, universal thermal insulation is suitable for roofing and filling interior partitions. It is produced in the form of Thermo Roll rolls with a density of 11 kg/m3, rigid sheets of Heat Plate (15 kg/m3) in the Pitched Roof and Acoustic versions. by the most large sizes rolled insulation is different: with a width of 1.2 m, its length reaches 6-12.5 m.
In the Insulation family, there was also a place for more practical thermal insulation made of basalt fibers:
- NTV - hydrophobized plates with a density of 35 to 150 kg / m3, laminated with foil or fiberglass. NTV Insulation panels are used for thermal insulation industrial equipment, but also on ventilated facades show their good side. They have a somewhat unusual size of 1x0.5 m, so consider this feature when installing the crate.
- LMF AluR - unusual mineral insulation where small strips of basalt wool are glued onto aluminum tape. The insulation is ideal for pipelines, laying under underfloor heating and installation on irregularly shaped building structures.
- FKD boards with a thickness of 20-180 mm and a density of 140-150 kg/m3 are used on facades with subsequent plaster finishing. The insulation has a high resistance to tensile loads (15 kPa). Only FKL lamellas with a transverse position of the fibers can compete with it - their peel strength of the layers exceeds 100 kPa.
- WM 640/660 GG is a special roll insulation reinforced with galvanized mesh. It is used to insulate chimneys, boilers and tanks where it is necessary to maintain a constant temperature.
- PVT are extra rigid slabs designed for floating screed or laying under cement grout. With a density of 175 kg / m3, they withstand a pressure of 50-60 kPa. Available in thicknesses from 20 to 120 mm.
- DDP - Knauf insulation for two-layer insulation flat roofs. The bottom sheets have a density of 105-110 kg/m3, specific gravity the top is in the range of 150-200 kg/m3. The compressive strength of the second layer reaches 70 kPa. Also in the DDP range there are plates for single-layer laying (RT, U and N) in rectangular and wedge shapes.
Rigid boards made of EPS foam, which is highly valued for its light weight, moisture resistance and excellent thermal insulation characteristics. The series is quite numerous, since it covers materials for all types of work that ordinary mineral wool cannot handle.
Used for underfloor heating concrete pouring or built-in heating system. Polyfoam Knauf Paul withstands a pressure of 1.4 kgf / cm2 and does not shrink. If such high strength is not needed, the Concrete range can be used for the floating screed. Sheets of this insulation work under load up to 1 kgf / cm2.
- Knauf Therm Facade.
Designed for external wall insulation and creates a flat surface suitable for plastering. This series also includes slabs from the Therm Walls line, used in frame construction, ventilation facade systems and for small-piece cladding.
- Therm Roof and Roof NL.
Heaters manufactured by Knauf for roofing. V basic version used only on the surface flat roofs, in the NL modification, they are also suitable for pitched. For insulation of roofs, attics and interfloor ceilings, you can also buy Therm Compack series slabs, designed for a load of only 0.6 kgf / cm2.
4. Therm "5 in 1".
A rather large group of universal foam insulation with the best characteristics.
- D - suitable for any structures that experience high loads: exploited roofs, load-bearing walls, foundations up to 6 m deep. The insulation of this brand is easy to recognize by the step on the edge and the applied mesh markings.
- C - option for external seamless structures for finishing with plaster. Excellent adhesion with various mixtures plates provides a textured surface.
- Insulation Knauf Term F - used to insulate walls, floors, as well as the foundation of a building, garden paths and basements. One of the most durable varieties of polystyrene boards that can withstand a pressure of 1.5 kgf / cm2.
What do buyers think?
“I am not enthusiastic about the new Heat Knauf insulation: too soft and some kind of “liquid”. Although in work they show themselves well, but only due to reduced dust formation. But it is difficult to find a place for them to use - you need a solid base and protection from above so that the cotton wool does not compress. In short, she has one road: the attic and the roof.
Artur Chernyavsky, Moscow.
“And I just resent Knauf's attempt to promote conventional foam at a clearly inflated price. I do not argue: it cannot be compared with our crumbling PSB-S insulation, but Knauf Therm is far from extruded polystyrene. Drainage grooves and a textured surface cannot increase the cost of the foam as much, so here the manufacturer is clearly greedy.
Konstantin, Moscow region.
“Knauf Dacha is not suitable for outdoor use, for indoor use with a big stretch, after all, the rolled insulation is made of glass wool. In general, this series seems to me extremely unsuccessful. Even a simple attic had to be covered with three rolls of insulation in order to somehow keep warm. I have Insulation slabs on the walls and have no problems. In the summer I will change everything to basalt.”
Ivan Viktorovich, Yekaterinburg.
“I read reviews about Knauf products, and I was very impressed that he did not prick his hands. When I tried it myself, I was convinced that there really is less dust. I also liked the thermal insulation in laying: elastic, light, does not spread. So I can’t even put a high cost in minus it. ”
Anton Tereshko, Nizhny Novgorod.
“If we take into account only thermal insulation Knauf characteristics, there are no complaints about him - he keeps the temperature in the house perfectly in any frost. But there is no sound absorption from the plates. On the first floor, it is not so noticeable, but in the attic, you can hear the metal tile in the rain like they didn’t put insulation under the roof.”
Vasily, St. Petersburg.
Summarize
Knauf impresses with an abundance of heat-insulating materials - in its assortment you can find everything to insulate your house from the foundation to the chimney. However, each series has its pros and cons, which must be taken into account:
1. Fiberglass in the Insulation and Teplo Knauf lines produces less dust than products from other brands. At the same time, it does not have the density at which one can seriously talk about sound insulation and strength.
2. Basalt fibers provide an order of magnitude better technical characteristics of the insulation. But so far, Knauf produces only special types of thermal insulation based on them - there are practically no universal offers in this series.
3. Polystyrene is the best option for total insulation. However, its fire hazard is not conducive to thoughtless use around the entire contour of the house. And the manufacturer obviously turned up the price, depriving the foam of the main advantage - accessibility.
Any Knauf insulation, provided it is used correctly, will be a good option for thermal insulation of residential and industrial facilities. In general, the materials of the German manufacturer please high quality, although for the price they are in the middle segment of the market. An excellent combination for those who want to buy the best, but are not ready to overpay for insulation.
Price
Without a doubt, the name of this company is known to anyone who has ever been seriously involved in construction or decoration. A very wide range of Knauf materials is presented on the Russian construction market, and all of them are in consistently high demand, as they are, one can safely say, a kind of quality standard.
However, in most cases, the Knauf brand is firmly associated with materials for finishing work - these are dry and ready-to-use building mixtures, soils, drywall systems with all the elements necessary for them, kits for "dry screeds" and other products of a similar plan. Meanwhile, the company also produces a very wide range of high-quality thermal insulation materials.
Insulation Knauf technical characteristics and types of which will be discussed in this publication is one of the most best options for the construction of private houses, since such thermal insulation is distinguished by the naturalness of the components, an increased degree of safety for human health. And, of course, when choosing any building materials, an important criterion, which is always given priority, is the reputation of the manufacturer. Well, in terms of high reputation and quality assurance of its products, Knauf is certainly “ahead of the rest”.
The Knauf company traces its history back to 1932 - it was founded by the Knauf brothers in Germany and at first bore the very long name "Reinische Gipsindustri und Bergwerksunternemen". Even from the name it is clear that the original direction of duration was associated with the production plaster mixtures from plaster. In the process of development of this private enterprise, the range of its products gradually expanded, and in 1949 a new plant for the manufacture of construction gypsum mixtures. In 1958, another "technological breakthrough" follows - the first production of sheets is opened for everyone now so well-known drywall.
Starting from the 70s of the last century, the assortment of the Knauf company goes beyond the scope of only gypsum products - mixtures using cement and lime are widely represented, construction chemicals produced by it, and ready-made structural parts are gaining popularity. Well, the next stages in the development are the development and implementation of the production of high-quality thermal insulation made of fiberglass, basalt fiber, and expanded polystyrene.
The Knauf company, with its investments in the development of production, came to Russia in 1993. Then other countries of the post-union territory followed - representative offices and production lines were opened in Kazakhstan, Moldova, Uzbekistan, Azerbaijan and Ukraine.
As a result, the company has grown from a small family business to the world's largest manufacturer of building materials. The transnational group of companies "Knauf" today includes more than 200 factories located in 37 countries in Europe, Asia, North and South America. In the territory Russian Federation products of this brand are produced at enterprises in Chelyabinsk, St. Petersburg, Novomoskovsk, Krasnogorsk, Kungur and other cities.
The obvious conclusion is that the company values its reputation very much and tries to fully support the popularity of its products. Therefore, goods with the Knauf brand for many decades have been one of the leading places in the construction markets of the world, deserve all the trust and never “stale on the shelves”.
It is also interesting that Knauf invests a lot of money in charity and in social projects. So, the company invested in recreating historic church Tyutchev's estate "Ovstug", sponsored the Prize. V.A. Zhukovsky on best translation literary or humanitarian work from German into Russian, actively promotes other projects in the field of culture, architecture, social policy.
So, as mentioned above, one of the areas of modern production activity of the Knauf company is the production of various types of high-quality thermal insulation. Let's address this issue.
Varieties of heaters "Knauf" according to the material of manufacture
Knauf heaters can be divided according to several criteria. Therefore, in order to make a choice, you need to consider them in more detail.
The first of the criteria can be called the material of manufacture. So, the heaters of this nonsense can be made of expanded polystyrene, or have a mineral fibrous structure.
- The Therm line of heaters is the company's expanded polystyrene thermal insulation « Knauf » , whose products are specially processed, and therefore differ from traditional boards from this material, made by other manufacturers. Heaters from this line are widely used in private and industrial construction for thermal insulation of walls, ceilings, roofs, foundations, balconies and loggias, and even road surfaces.
- "Teplo Knauf" is a line of heaters made of fiberglass and basalt fiber and used in private construction for thermal insulation. various parts Houses.
- "Knauf Insulation" - insulation materials positioned as professional thermal insulation made from basalt fiber. This type of insulation is also divided into several types, designed for use on various building structures of the building.
Let's move on to a more detailed consideration of the characteristics of heaters of various types, to a more substantive subdivision of them according to their areas of application.
Heaters "Knauf Therm" based on expanded polystyrene
"Knauf Therm" - technical characteristics and applications of heaters
Knauf Therm rigid boards are produced using the same technology as other foam insulation from extruded polystyrene foam. However, in keeping with the concept of maximum care for the health of consumers and the preservation of the environment, Knauf's technologists have successfully replaced some of the toxic ingredients with completely safe components.
For example, a manufacturer abandoned chlorine-containing compounds, which are almost always included in the foam of other manufacturers, since these components greatly simplify the production process of such insulation. In addition, these products can be classified as safe, as they do not contain aldehyde and phenolic compounds that emit toxic fumes that are extremely harmful to the health of those living in the house.
The general operational and technical characteristics of Knauf Therm polystyrene foam heat insulators are as follows:
- The thermal conductivity coefficient, depending on the specific product and its operating conditions, lies in the range of 0.31 ÷ 0.42 W / m × ˚С.
- Density - 10 ÷ 25 kg / m³.
- Compressive strength - 20÷170 kPa.
- The temperature regime of operation lies in the range from - 135 to + 80 ˚С.
- The vapor permeability coefficient is 0.02÷0.03 mg/(m×h×Pa).
- Moisture absorption coefficient for 24 hours - 0.8÷2.0% by volume.
- Flammability class G1÷G3. Thanks to the processing of Knauf expanded polystyrene boards with modern fire retardants, they are a low-flammable, self-extinguishing heat insulator.
The boards are sold in packages made of polyethylene protective film. Due to their light weight, they are easy to transport, carry, lift to floors, and install them.
Advantages and disadvantages of polystyrene foam insulation of the Therm line
Before proceeding to consider the technical aspects of Knauf Therm thermal insulation, it makes sense to consider its "pros" and "cons". Such a review, by the way, is also able to very “colorfully” characterize the insulation from many important aspects, since not everyone understands the dry numbers of the tabular parameters.
So, polystyrene foam insulation Knauf companies are widely popular due to their many advantages. These include:
- Low thermal conductivity expanded polystyrene is the most important property for a heater. So, the heat-insulating qualities of this material, having a thickness of 120 mm, can be compared with the same parameters of a brick wall of 450 mm or a concrete structure with a thickness of 2100 mm.
- moisture resistance. Expanded polystyrene practically does not absorb and does not allow moisture to pass through, so it is well suited for insulating such areas of the structure as the foundation, basement, facade and roof. Due to the fact that water does not penetrate into the structure of the plates, it is not able to act destructively on the material and reduce its thermal insulation properties.
- Small specific gravity. Plates "Knauf Therm", despite the significant geometric dimensions - are quite light, due to the fact that their structure consists of almost 98% of air. Due to its low weight, this insulation will not make the load-bearing structures heavier, will not create additional load on the foundation of the building. The issues of loading and unloading, transportation of material and its supply directly to the place of work do not constitute any particular problems. Reinforced fasteners are not required for fixing.
- Sufficient mechanical compressive strength and resistance to the corresponding deformations allows the use of such insulation for thermal insulation of load-bearing or load-bearing structures. For example, special slabs are great for thermal insulation of screed floors and for creating “warm floors”.
- Wide operating temperature range indicates that the material will function perfectly both at extremely low temperatures (without restrictions from theoretically possible), and at elevated temperatures, reaching up to 80 degrees, and at a short time- and up to 95 degrees.
- Ease of installation work allows them to be carried out even by an inexperienced master. Plates are easily marked and cut with a regular hacksaw, a sharp clerical or construction knife with replaceable blades.
- Low toxicity. Due to the exclusion of a number of potentially hazardous components from the original component composition, Knauf expanded polystyrene does not emit into environment harmful substances.
- Affordable price. Extruded polystyrene foam boards traditionally belong to the category of the most affordable thermal insulation materials among all heaters on the construction market.
With all the numerous and very significant "pluses" of this material, it has no less significant "minuses". However, Knauf's technologists, as far as possible, using innovative technologies, have reduced the negative aspects that are inherent in foams from other manufacturers.
So, the disadvantages of polystyrene foam boards include their following qualities:
- Low resistance to open fire. This material belongs to the flammability class G3. This, however, is not the highest degree of flammability, that is, the material is capable of “resisting” an open flame for a certain time, but nevertheless ...
Thanks to modern materials and technologies for their processing, the developers of Knauf Therm managed to make the heaters of this line self-extinguishing (according to the manufacturer, in the absence of contact with fire, the heater instantly goes out on its own). However, despite such innovations, at temperatures of the order of 300 ÷ 450 degrees, depending on its density, the material, when melted, is capable of becoming a fire spreader itself. At the same time, expanded polystyrene, unfortunately, during combustion also emits extremely dangerous gaseous products that can cause irreparable damage to human health.
- Low level of sound insulation. With this quality, the foam is significantly inferior to heaters made on a fiber structure. True, it is possible for him to muffle a quiet knock and vibration, but a layer of expanded polystyrene plates is not able to contain acoustic waves - it does not reflect or absorb them, and in some cases even becomes a resonator, turning into a kind of "drum".
- Poor resistance to many aggressive chemical solutions. When solvents, alkalis or acids get on the plates, the structure of the material is very quickly destroyed, the insulation is deformed, and loses its thermal insulation qualities.
- Low UV resistance. Expanded polystyrene installed on the outer surfaces of the building must be covered with a layer as soon as possible finishing material, as the sun's rays destroy its structure.
- Low vapor permeability. Styrofoam is not a "breathable" material, and the lack of free movement of water vapor can lead to condensation between insulating layer and the wall of the building - in case of their incompatibility in this parameter, as well as in case of improper installation. In any case, this imposes certain restrictions on the use of "Knauf Therm" as thermal insulation in certain areas of construction or requires a specific approach to the design of the insulating "pie".
- Susceptibility to material damage by rodents. Expanded polystyrene does not represent any nutritional value for mice or rats, but it is not toxic to their organisms either. The structure of the plates allows these animals to easily damage thermal insulation, and in products with a large thickness, mice gnaw holes and even sometimes equip their "dens". Therefore, choosing this material for external insulation of the lower part of the foundation and basement, it must be reliably protected with a durable decorative and finishing layer that will be too tough for rodents.
Types of polystyrene foam thermal insulation of the Knauf Therm line
The Knauf Therm line is divided into several groups of heaters, which are designed for thermal insulation of various house structural elements.
- Knauf Therm Roof ("Roof") are materials used for thermal insulation of roofs, interfloor and attic floors. In turn, this group of expanded polystyrene is divided as follows according to the field of application:
- "Roof" is used for insulation of flat roofs;
- "Roof NL" for pitched structures;
- "Roof Light" for insulation of ceilings from the inside of the building.
Such boards are manufactured in widths from 200 to 1200 mm, lengths from 600 to 3000 mm, thicknesses from 20 to 1000 mm (at the request of the customer) in increments of 10 mm. The material has a compressive strength of 100 kPa, a thermal conductivity of 0.039 W/m×°K, and a density of 17.0 kg/m³.
- Knauf Therm Wall ("Wall") - as the name implies, this insulation is usually used for thermal insulation of walls frame buildings, in systems of ventilated facades. Plates are produced with a width of 1000 mm, a length of 1000÷1200 mm, and a thickness of 50 to 200 mm. The material has a compressive strength of 40 kPa, a thermal conductivity coefficient of 0.044 W/m×°K.
- "Knauf Therm Facade"- slabs intended for external thermal insulation of walls, for installation in ventilated facades, as well as using the “wet facade” technology, that is, for further plastering with subsequent finishing with decorative plaster, painting with facade paints or tiling. Facade slabs are produced with a width of 1000 mm, a length of 1000÷1200 mm, a thickness of 20.50, 100 and 150 mm. Compressive strength - 100 kPa, thermal conductivity coefficient 0.038 W / m × ° K, density 17.0 kg / m³.
- Knauf Therm Floor ("Floor") - is used for warming floors and ceilings and is designed for increased load for compression. The material does not shrink, so it can be used both in residential areas, where it will experience a small load, and in garages, where the pressure on it will increase significantly. This insulation has one of the highest compressive strength, which is 120 kPa. Thanks to this property, after laying it, you can immediately equip a reinforced concrete screed. The resulting structure, with high-quality concrete and the observance of the technology of its pouring, will last for several decades without repair. Products are produced in widths of 1000 mm, lengths up to 3000 mm and thicknesses from 20 to 600 mm (in 10 mm increments) and have a thermal conductivity coefficient of 0.038 W/m×°K, a density of 20.0 kg/m³.
If the insulation is placed in a room with a small amount of traffic or other dynamic load, then plates can be used as this Knauf Therm Concrete, which is designed for a load of 1.0 kgf / cm². In this case, it will be possible to save money, since the price of this material is slightly lower than the previous option.
- "Knauf Therm Warm floor" - the surface of this material has a specific relief, which is intended for convenient installation between its bosses of the contours of pipes of a warm water floor.
This heat insulator has its own technical and operational characteristics, which include the following indicators:
- tensile strength - 140 kPa;

Advantages and disadvantages of Knauf mineral wool insulation
When choosing a thermal insulation material for different applications, almost all developers are purposefully looking for an option that will combine the maximum number of positive qualities. The insulation should ideally be vapor-permeable, that is, "breathable", made from environmentally friendly components, that is, it should not emit fumes harmful to humans, and most importantly, have minimal thermal conductivity. All these qualities are possessed by Knauf fibrous insulation materials, the range of which is quite wide and designed for use in various conditions operation of building structures.
If we consider each of the advantages separately, then they will be characterized as follows:
- Low thermal conductivity insulation materials « Knauf » reliably retains the generated heat in residential premises, which allows achieving comfortable temperatures at any time of the year, with very significant energy savings.
- High vapor permeability mineral wool materials contributes to the creation of a favorable microclimate in the house with a normal level of humidity, which reduces the risk of the appearance and development of colonies of fungus or mold on the walls and at their joints with the ceiling.
- Incombustibility mineral heaters. Similar thermal insulation materials « Knauf » belong to the NG class (non-combustible), which allows them to be used for thermal insulation in any type of building.
- High level of sound absorption makes this material an excellent solution for soundproofing your home from outside noise.
- Relatively light weight mats and rolls of insulation allows you to transport and install them yourself, without resorting to outside help. In addition, the insulation does not overload the supporting structure of the house.
- Biological and chemical resistance. The components from which heaters are made do not enter into chemical reactions with other materials, they do not rot, have no smell, and also prevent the development of pathogenic microflora.
- Long service life– it is usually estimated at 50 years or more.
- "Manufacturability" of the material, that is, the convenience in its installation. When it is installed between wooden posts or joists, the mats fit tightly to them, leaving no gaps. Heaters are resistant to vibration, do not shrink, do not delaminate and retain their shape for the entire period of operation.
- In the production of heaters, no harmful formaldehyde components, dyes or bleaches are used, therefore Knauf mineral wools are completely safe in this regard for the residents of the house.
With so many advantages, mineral heaters « Knauf » nevertheless, they have some disadvantages, which you also need to be aware of when choosing the materials necessary for construction:
- One of the "minuses" for many is decisive - this is a high price, so not every owner of a house under construction or reconstructed can afford such thermal insulation.
- Low level of moisture resistance. But, however, in order to preserve the performance characteristics of the insulation for as long as possible, it is subjected to special steel processing at the factory according to the developed by the company « Knauf » technology "Aquastatik", which at times increases the resistance of mineral wool to moisture.
- In the production of some materials for thermal insulation, fiberglass is used, which somewhat complicates the installation of insulation, since when working with it, it is necessary to protect open areas of the body, as well as organs of the respiratory system and eyes. To prevent the smallest particles of insulation fibers from entering the airspace of residential premises, the thermal insulation layer must be covered with another material that does not allow dust to pass through.
Mineral wool "Knauf" - characteristics
Insulations made from fibers obtained from natural raw materials (such as sand, basalt and natural resins) processed using modern Knauf Ecose technology are sold in rolls and mats. The material does not contain harmful substances, rodents and insects do not start in it, and in addition, it is quite resistant to external influences even if installation errors are made.
This type of product is divided into two main lines:
- The first product line is TeploKnauf. Such materials can be safely used by the owners of houses and apartments for thermal insulation of balconies, walls and floors from inside the building, as well as for facade surfaces. However, if this thermal insulator is planned to be used for external insulation, then it must be additionally protected from moisture by covering it with a waterproofing membrane.
This line of heat insulators is made from both glass fiber obtained from molten sand and glass waste, and from basalt fibers.
- The second line is called "Knauf Insulation" and is intended mainly for use by professional builders. This group of heaters is produced only from basalt fibers, which are obtained by melting natural rocks.
To understand how these lines differ, and what characteristics specific types of heaters have, it is worth considering each of them in more detail.
Heaters from mineral wool of the TeploKnauf family
"TeploKnauf" is a mineral wool produced using innovative technology, which has the so-called "3D-elasticity". Due to this quality, the material has increased elasticity, that is, it easily compresses and straightens, returning to its original shape and thereby ensuring the tightest possible fit to the insulated surfaces and to the elements of the frame crate, preventing the occurrence of cold bridges.
The materials of this line are perfectly adapted for use in residential construction, they are safe for the residents of the house, as they are made without the use of acrylic and phenol-formaldehyde resins. Any of the mineral wool in this series is processed water-repellent impregnations"Aquastatik", therefore, has good moisture resistance, almost on the border with hydrophobicity.
In turn, "TeploKnauf" are divided into three groups that have their own characteristics and purpose, which, in principle, is reflected in their name:

What layer of insulation is needed for a specific case of thermal insulation work?
The presence of such a large number of types of Knauf thermal insulation on sale can make it difficult to choose the one necessary for a particular site (building structural element) that requires insulation - but here you can focus on the recommendations received in the article. But the amount of material will already depend on the area of \u200b\u200bthe insulated structure and the required thickness of thermal insulation.
To get an answer to such questions, it is recommended to contact specialists who will determine all the necessary thermal insulation parameters on the spot. But very often such calculations can, with a sufficient degree of accuracy, be carried out independently.
How to find the area of the insulated structure in this article we will not tell - there is a separate publication for this.
Calculate area? - no problem!
It happens that the intricate configuration of a room, wall, roof slope or other building structure confuses when determining the area. If such a situation happened - refer to the publication of our portal, specially dedicated - there are considered various options, convenient online calculation calculators are provided.
So, the main snag is how to determine the required thickness of insulation. And here a certain thermal engineering calculation is required. We will not give formulas - they are all included in the program implemented in the online calculator, which will simplify such calculations as much as possible.
The meaning of the calculation lies in the fact that a properly insulated building structure must have a total resistance to heat transfer not lower than that established by SNiP for a particular region (in accordance with its climatic features). This value includes the thermal resistance of the structure itself plus the resistance of the insulation. Thus, if the design parameters are known (its structure, the thickness of the layers and the material of their manufacture), then it is easy to calculate what thickness of insulation is needed to make up for the "deficiency" of thermal resistance, which is missing to the normalized value.
Mineral wool insulation is akin - this is probably the most ancient material of this type, which was launched into constant and mass production. In this type of insulation, the basis is made up of remelted fibers, which have excellent thermal conductivity and are very easy to use.
With the help of these materials, it is possible to finish walls, load-bearing structures, ceilings, roofs, etc. Very different companies produce mineral wool insulation: Rockwool, TechnoNIKOL, Knauf, Izover, etc. Almost every product line in the range has a certain number of mineral wool models.
However, it is the Knauf company that completely specializes in wool insulation. About the products of this manufacturer will now be discussed.
1 Features, purpose and properties
It is unlikely that you will be able to meet at least one person who would not have heard of a company like Knauf. This German manufacturer over the past few decades has grown into a giant concern with a bunch of enterprises around the world.
Only goods from Rockwool, Izover or TechnoNIKOL can compete with him in the local market. The company produces building materials for home decoration. Moreover, this applies to both the finishing of walls and the installation of thermal insulation, waterproofing, etc.
Even concrete mixes, and those can be bought from Knauf. If desired, the whole house can be assembled using Knauf products in almost every production process.
Separately, we note the Knauf insulation, which is discussed in this article. Knauf insulation is characterized by the use of exclusively mineral wool materials.
This is a unique feature of the company. The manufacturer was able to launch and sell several lines of such products during its entire stay on the market, using its own unique technologies.
As a result, they managed to create a practical ideal insulation for walls, load-bearing structures, roofs, floors, etc. Any private house or a cottage can be finished with heat-insulating materials from the foundation to the roof itself, using only products from Knauf.
Mineral wool was similarly chosen because of its excellent characteristics. This material is produced using a rather interesting technology. In the production of cotton wool, it is necessary to melt mineral rocks, then process them and extract special fibers from them. It is from these fibers that the body of mineral wool is created.
The use of mineral rocks makes such material practically non-combustible, contributes to its resistance to external influences and avoids contact with rodents.
In most cases, rodents can still settle inside the insulation, but the Knauf company has also applied a special production technology here, which has reduced such cases to a minimum.
Let's look at the main pros and cons of Knauf mineral wool insulation.
Main advantages:
- Durability;
- Practicality;
- Low thermal conductivity (at the level of 0.035 W / m);
- Ease of installation;
- A light weight;
- Does not burn in fire;
- Easily handled like ;
- Vapor permeability
- Environmentally friendly and completely safe material for humans.
Main cons:
- Pretty high price;
- Some vulnerability to contact with water.
Note that Knauf insulation is not as susceptible to reactions to moisture or water as other materials from other manufacturers. That is why it is often used to insulate not only internal walls, but also facade walls, as well as foundations.
However, it is better not to abuse such things. If you look at customer reviews, you can understand that even though cotton wool slightly absorbs moisture, it will still swell after a couple of months of operation in difficult conditions, and this already promises big trouble in the future.
As for the price, the insulation for walls or load-bearing structures made of mineral wool, of course, will cost you more. But reviews of this product, and its technical characteristics, signal the exceptional quality of the material. And you have to pay for quality.
2 The main types of insulation
The Knauf company produces heaters in different configurations (there are even analogues). All of them have their own specifications, dimensions, etc. In order to perfectly understand all the features of heaters, it is necessary to evaluate their characteristics, reviews, take into account the scope and cost.
But first, it’s better to think in advance what kind of work you need to do. After all, it is quite obvious that the insulation for the walls will differ from the similar material for the roof.
Plus, it is important to note that the Knauf company is engaged in the production of at least 8 models of heaters, and they are also divided into two larger subspecies.
There are line heaters:
- Insulation (Insulation);
- TeploKnauf.
Models from the Insulation line are used in professional construction. Their technical characteristics have been significantly improved due to the improvement of production technologies and the use of more expensive raw materials.
But the TeploKnauf line performs slightly different tasks. A heater from this subspecies is needed when it is necessary to arrange thermal insulation for a private house or cottage. It can also be used for industrial purposes, but the effect in work will not be so impressive.
According to a similar technology, the division of goods is carried out by the companies Izover, Rockwool, TechnoNIKOL. Izospan with his, etc. But it is Knauf who is engaged in the production of exclusively mineral wool insulation, and even in such a large mass of varieties.
Rockwool products do not have such a wide range of products provided (the same applies to Isover), and the guys from TechnoNIKOL specialize more in foam insulation.
2.1 TeploKnauf line
We will dwell on the TeploKnauf line in more detail, because these products are used in the vast majority of cases. It is understandable, because the share of civil construction in our time is much larger than the share of industrial construction.
There are several of the most popular varieties of Knauf heaters:
- TeploKnauf Cottage;
- TeploKnauf House;
- TeploKnauf Dacha.
Each of them has its own unique technical characteristics, is produced in a separate package and is designed to perform specific tasks.
So, TeploKnauf Cottage is used, as the name implies, for finishing cottages. Although you can use it almost everywhere. The product is sold in rolls.
This is his feature. Model Cottage in slabs is impossible to buy. It is used for insulation of partitions, various kinds of ceilings, walls, and in extreme cases, even floors.
Teploknauf Dom or Dom+ is used when it is necessary to insulate wall or roof frames. The peculiarity of TeploKnauf Dom is that it is produced in the form of plates, and the plates are very elastic.
Their compression ratio can reach up to 50% like . This means that more material will fit in the TeploKnauf Dom package, since it is simply easier to press it.
It is especially convenient to use TeploKnauf Dom when arranging thermal insulation of the roof. These plates can simply be placed between the rafters, and due to their elasticity, they will quickly occupy all the space and fill the openings with their volume.
TeploKnauf Dacha is also sold in rolls. This is the cheapest insulation, which, in fact, is used for conventional insulation of attics, floors in the country, etc. Its technical characteristics are also relevant. But it is worth noting that the reviews about the TeploKnauf Dacha insulation are mostly positive.
You just need to understand that such models are represented by simpler production technologies (rolled insulation is always easier to produce), since they are intended to provide elementary work on the installation of thermal insulation.
Otherwise, the technical characteristics of materials from the TeploKnauf model range do not differ from each other. All of them have a thermal conductivity of 0.035-0.037 W/m. Quite resilient, non-combustible and poorly responsive to moisture.
2.2 Insulation line
If the TeploKnauf Dom or Cottage insulation is used to protect the walls of private houses, then the products from the Insulation line are used when it is necessary to handle large building volumes.
These will not necessarily be plants or factories, they are also used in the construction of large civil buildings: hotels, shopping centers etc. That is, wherever there is a large amount of work and a significant scope.
The following heaters of the Insulation line are distinguished:
- Thermo Stove;
- Thermo Roll;
- Acoustic partition;
- Pitched roof.
Thermo Plate is intended for processing walls. Thermo Roll is roll material from dense mineral wool mats, which are then rolled and packaged. The difference between the above two options is minimal.
In some situations it is easier to work with slabs, while in others it is better to deal with rolls. As for the technical characteristics, in addition to the dimensions, they are almost the same.
Acoustic partitions are produced both in the form of plates and in the form of rolls. This type of mineral wool is characterized by extremely high elasticity and the ability to dampen serious noise.
Knauf Pitched roofing has the best waterproofing in its class. Roughly speaking, it does not absorb water at all, as it is a water-repellent material. For mineral wool, this indicator is a big plus.
