Foreword. Insulation of buildings allows you to reduce the cost of space heating, create a comfortable microclimate inside and increase the operational life of all load-bearing structures of the house. The use of rockwool mineral wool is a simple and affordable technology for many, thanks to which effective insulation can be achieved. Let's take a closer look specifications Rockwool insulation.
Rockwool technology, specifications
Rockwool is an ecological material that is obtained by melting rocks and pulling them into thin threads impregnated with a binder. The result is stone wool with a fibrous structure. The production technology makes it possible to produce strong, moisture-resistant and easy-to-handle boards with improved sound-absorbing properties and mechanical resistance to compression.
Materials production technology
Thin and elastic threads create chaotic weaves and provide high resistance of the material to deformation and shrinkage. The basalt component for the production of mineral wool provides incombustibility and guarantees increased strength of products under the Rockwool brand. In Russia, there are two factories of the company - in the city of Zheleznodorozhny and in Vyborg, they are equipped with the most modern equipment for production.
The Rockwool group of companies is a world leader in the production of materials for insulating rooms - ceilings, floors, partitions, facades of houses. For each design there are special materials produced by Rockwool. In Russia, Rockwool materials based on mineral wool are very popular, as is Isover mineral wool among large construction companies and individual developers.
Technical characteristics of Rockwool insulation
Rockwool produces a wide range of products in the form of rolls and plates. The following types of thermal insulators "Light Butts", "Facade Butts" and "Acoustic Butts" are in the greatest demand today. Rockwool mineral wool has different technical characteristics, and depending on them, the plates are used inside or outside buildings. The main characteristics include:
Thermal conductivity. Rockwool mineral wool has the best indicator among competitors - 0.036-0.038 W / m K (Watt per meter per Kelvin). The effectiveness of thermal insulation directly depends on this indicator. And the density of the material provides maximum energy efficiency of a residential building.
combustibility(fire resistance). Stone wool belongs to the class of non-combustible materials (NG) and can withstand temperatures up to 1000 degrees Celsius. In the event of a fire, the insulation does not emit smoke and prevents the spread of fire in the room.
Deformation resistance It is provided by a chaotic arrangement of the thinnest fibers, which ensures their dense interlacing, rigidity and stability of the shape of the mats. Facade Butts mats are used as thermal insulation of the facade - they are dense and rigid, resistant to deformation. In addition, Flexi mats have a springy edge on the long side of the board.
Vapor permeability. Hydrophobicity and vapor permeability determine the ability of a material to absorb and repel water, as well as to pass air. If you do not make a vapor barrier during the installation of the insulation, then the thermal insulation qualities will begin to decrease as moisture is absorbed. Light Butts waterproof mats are used in lightweight structures as a non-load-bearing layer.
Soundproofing. The ability to protect the room from noise from the material at a height. Between the fibers of the material is a layer of air, which delays all sounds. The degree of sound insulation is affected by the density and porosity of the Rockwool insulation structure. Sound-absorbing mats Acoustic Butts provides sound-absorbing capacity (within 43-62 dB).

- plates perfectly resist mechanical influences, are easy to install and quickly cut.
"Rockwool" characteristics and origins
Rockwool stone wool slabs are made from natural stones Therefore, they are used in almost any construction industry. The production process of stone wool resembles a volcanic eruption, since this is how it is naturally produced.
In order to make stone wool, ordinary stone is used, which is melted in a special furnace to a temperature of 1400-1500 degrees. The material forms an alloy, which is affected by powerful air currents, turning it into cotton fibers. With the help of additives, they are shaped and made moisture resistant. From this material, a material is formed in the form of plates, which, after hardening, is ready for use.
When studying the reviews about the Rockwool insulation, a number of characteristics that it possesses should be highlighted: environmental friendliness, Fire safety, heat resistance, sound insulation and durability.
On plates "Rockwool" the price depends on such factors as:
- characteristic of the plate;
- her appearance;
- the presence of additional properties or layers;
- the amount of material required;
- scope.

Roofing system “Rockwool”
Considering the insulating materials "Rockwool" for roofing, several types of roofing should be distinguished on which they are used. There are heaters for:
- exploited roof;
- roofs of soft type;
- adhesive roofing.
The roof is a top covering that bears a lot of load, so the materials used for its thermal insulation must be of high quality.
Since the main function of the roof is to protect the building from precipitation, in the form of rain or snow, therefore, the appearance of leaks is the worst damage to it.
The company "Rockwool" is engaged in the production of roofing thermal and waterproofing systems. This system is a type soft roof, on which there is no upper screed, and the top layer is covered with a waterproofing carpet. The roofing system consists of basic and additional elements, which make it possible to complete installation soft roof. The main part is profiled steel sheet and reinforced concrete slab.
The system includes components that have been repeatedly tested for compatibility and are characterized by a long service life of more than 45 years. Thanks to the installation of a PVC membrane and a vapor barrier layer, water vapor escapes from the room and, thus, the heating layer is dried independently. This process avoids the accumulation of moisture, the occurrence of mold and fungus, and also regulates the humidity in the room.
Roofing system "Rockwool" includes the presence of:
- films for the implementation of vapor barrier;
- heat-insulating boards;
- systems for fixing components on the roof;
- roofing waterproofing membrane;
- stone wool parts, designed for installation on sloping surfaces.
The main advantages of this system are:
- lightweight construction that does not load the building;
- high level of thermal insulation properties;
- resistance to mechanical stress;
- strength of mechanical fixation;
- the use of fireproof heat-insulating plates that protect the structure from the formation of fires and the spread of flame;
- the system provides maximum protection against atmospheric precipitation;
- quick and easy installation, as well as repair space;
- roof is installed on pitched roofs, and on roofs with a zero clone;
- high and long-term performance.
Rockwool video:
One of the most popular thermal insulation materials presented on the world market is ROCKWOOL insulation. The international holding ROCKWOOL produces several types of goods for various purposes. The main direction was and remains the production of non-combustible insulation. ROCKWOOL produces thermal insulation products under the eponymous brand in 27 countries.
Low thermal conductivity of mineral wool
The main function of any heat-insulating material is the creation and maintenance of a comfortable indoor microclimate. Which substances best meet this requirement? These are substances with low thermal conductivity. Manufacturers of heat insulators started making mineral wool insulation several decades ago. Mineral wool is the thinnest fibers compressed by a binder into a web with a thickness of 50 mm to 100 mm.
Today, the market offers fiberglass insulation, which contains sand and recycled glass. Stone wool made from basalt rocks.
stone wool
Stone wool is one of the varieties of mineral wool.
Stone wool is produced by melting basalt volcanic rock at a temperature of about 1500 C and simultaneously drawing fibers with the addition of binder components and water-repellent compounds. As a binding element, resole resins (thermosetting) are used, which are the product of the condensation reaction of phenols with formaldehyde. In the final product, the resins pass into an infusible and insoluble state, therefore they are safe for human health.
The studies carried out on the material allowed the experts to give a positive conclusion on product safety. Rockwool was one of the first companies to receive the EcoMaterialGreen certification.
Characteristics of Rockwool insulation
Insulation pack
Production features and starting materials determine the following physical and mechanical properties of Rockwool insulation:
- The best thermal conductivity coefficients among heaters of this class: 0.036 - 0.038 W / mK. The working thickness of the insulation is 50 mm.
- During long-term operation, there is no shrinkage of the web, due to the unusual structure and randomly arranged fibers. This distinguishes it from fiberglass, in which the fibers are arranged almost longitudinally. It also has a positive effect on the rigidity of the material and resistance to tearing.
- Due to the mechanical interaction of the fibers with each other, the insulation after vertical installation does not fold under its own weight.
- The thermal conductivity is significantly affected by the density of the material, that is, the ratio of mass to volume. The lower the density of the substance, the higher the thermal insulation properties. The density of Rockwool is about 35-37 kg/m3.
- Processing in the production process with water-repellent oils ensures the hydrophobicity of the insulation - the ability not to absorb moisture, repel water. Therefore, there is no destruction of the material in a humid environment, which allows it to be used for thermal insulation of wet rooms.
- Rockwool insulation has a high vapor permeability, which is more than 0.25 mg / (m x h x Pa). The insulation is able to pass through itself water vapor and air. Consequently, moisture condensate does not accumulate in structures with ROCKWOOL thermal insulators. The walls and the whole house breathe freely.
- The heater works and how soundproof material. The sound wave, passing through the rockwool layer, attenuates in it, sound absorption occurs. The overall noise level in the rooms is low.
- The structure of the insulation is such that it has many air pores, so it is easily compressed, the compression is about 30% of the original volume.
- The melting temperature of the insulation fibers is over 1000 C, therefore, under fire conditions, the material provides fire protection for building structures, delays the process of destruction of bearing supports.
- No living organisms can be inside this inorganic material and feed on it. It concerns small rodents, microorganisms, bacteria.
Applications
Rockwool can be used in different rooms
Thermal insulation materials of the ROCKWOOL brand after certification studies have conclusions on compliance sanitary standards and rules. They are recommended for use in external and internal structures of any type of buildings: residential, public, including medical and children's institutions, as well as industrial facilities, in Food Industry inclusive.
Heaters are produced in the form of plates, rolls for ease of installation in various designs. For example, rigid FACADE BATTS boards are used for facade insulation, while LIGHT BATTS SCANDIC boards are used in private construction. "Vapor barrier for roofs, walls, ceilings" is produced in rolls and is used to protect load-bearing structures from the flow of water vapor.
So, ROCKWOOL products can be divided into several groups:
- Rigid plates;
- Light slabs;
- Plates with additional rigidity;
- Rolls.
There are currently a lot of heaters, and they all differ from each other in the composition of raw materials, features of production technology, quality and price. Rockwool brand insulation is not inferior to other thermal insulation materials either in its properties or ease of installation, and is one of the most popular heaters that are chosen by both professionals and people involved in construction on their own.

Knowing the properties of a stone slab will help you understand whether it is worth buying just such a heater.
Mineral wool firmly occupies a leading position in the world as heat and sound insulating materials both in terms of production volume and in terms of the number of houses insulated with their help. In Europe and Asia, the most famous and recognizable is Rockwool insulation, which has won such close attention with high quality standards and constant updating of the product line, innovative products with unique properties or distinguished by a strict purpose, where other similar heaters cannot compete with them.
About the manufacturer
Rockwool is an international company with roots in Denmark. He has been dealing with stone wool-based heaters since the thirties of the last century. An important step towards development was the acquisition of factories in Germany and a number of other European countries, as well as the foundation of its own design office in 1957. This gave a powerful impetus to the development of both the Rockwool company itself and the insulation. Basic modifications of rolled insulation, rigid plates with different performance characteristics were created. The modern product range already includes several dozen highly specialized thermal insulation materials with optimized characteristics.
Rockwool insulation has officially appeared on our market since 1995 with the opening of a sales office. Already in 1999, the first plant was launched. In total, the market presents the products of four factories operating in Russian Federation on local raw materials and in strict accordance with the technologies and quality control of the international company Rockwool:
- G. Zheleznodorozhny, Moscow region;
- Vyborg, Leningrad region;
- Troitsk, Chelyabinsk region;
- SEZ "Alabuga" Republic of Tatarstan.
Mineral wool
The mineral wool group used for thermal insulation includes:
- glass wool;
- stone wool;
- slag wool.
It is stone wool obtained by melting rocks of volcanic origin that has the best performance and safety. This served as an impetus for the technical development and improvement of stone wool, and in particular basalt wool, which made it virtually no alternative.
stone wool
Under the definition of stone wool falls any material obtained by melting rock, followed by blowing thin threads. In different parts of the world, naturally, the mineral composition of fossil resources also differs, from which the characteristics of mineral wool from manufacturers and trademarks may vary, as will actual performance.
Basalt wool
If we consider mineral wool produced by the Rockwool concern, then it can be fully classified as basalt. A group of gabbro-basalt rocks was recognized as the main ingredient, from which it is possible to blow high-quality fiber with excellent mechanical properties. Equally important is the qualitative combination of additional components, such as a binder, hydrophobic additives, etc.
The development of the technology for the production of mineral wool, as well as all the innovative achievements of the Rockwool company, since 1957 after the formation of the design office, is associated precisely with the improvement of the properties and qualities of the used basalt wool.
Product List
A distinctive feature of Rockwool products is their intended use. In the product range there are highly specialized products, the purpose of which is strictly regulated by the manufacturer and the result of insulation is guaranteed precisely with the intended use of materials.
It is worth noting that the eternal dispute of consumers in various construction forums is tied to the density of a particular brand of mineral wool. This parameter is elevated to the absolute when considering efficiency, usability and durability. This is one of the reasons why Rockwool generally does not specify the density of mineral wool on many product lines.
The company's specialists thoroughly deduce the ideal parameters of mineral wool, the method of its manufacture, the final operational properties and characteristics in order to obtain a guaranteed result if the installation rules are followed. It's tied to the combination. a large number parameters and properties, among which the density actually fades into the background.
Such a remark is needed to explain how important it is to know about the very availability of a wide range of Rockwool solutions, that for any task in construction and insulation you can find The best decision. First of all, in terms of predictability and immutability of the result.
Light Butts
Basic, or rather universal solution. Mineral wool boards of medium hardness, excellent for insulation frame walls, partitions, individual premises such as balconies, loggias, attics. Insulation of floors is allowed only along the logs. Plates are not designed for additional load.
Starting from Light Butts and beyond, almost all types of Rockwool insulation are made using flexi technology, which means that one of the sides of the plate along the edge is somewhat softer and springier. This helps to lay the material along the crate faster and better, without creating unnecessary deformations and loads on the main part of the slab. It also guarantees that the laying of mineral wool on the crate with a well-maintained step will be dense without cracks and gaps. The manufacturer also guarantees that there will be no shrinkage of the heater during the entire period of operation.
Light Butts SCANDIC
A series created for the insulation of a private house. The performance characteristics repeat exactly the properties of the conventional Light Butts, and all the innovations relate to the transport and installation features associated with the material. Light Butts Scandic is packed in sealed packages in a compressed form, when the plates take up a third less volume. This means that packages with a standard amount of insulation can easily fit into passenger vehicles or more into a truck.
The main constructive thought concerns the method of manufacturing insulation boards so that after any even prolonged deformations, the board returns to its original shape.
Facade Butts
Plate dimensions - 1200x500 (600) mm, thickness 50-180; 1000x600 mm, thickness 25-180 mm;
The purpose of the Facade Butts insulation is to create heat-insulated facades with a thin layer of plaster. The density of the plates is increased compared to conventional Light Butts. It is mounted on a surface with mechanical fastening by plastic expansion bolt shields with a wide head.
Venty Butts
A group of semi-rigid insulation boards, intended primarily for the arrangement of ventilated facades. There is no need to use wind protection for them, which reduces the cost of work and speeds up installation. Dry mechanical fastening with the help of special dowels, the number of which is determined by the construction or insulation project.
floor butts
Durable insulation boards with special impregnation with hydrophobic compounds. Designed for thermal insulation of floors and ceilings under a floating screed with a high sound absorption coefficient. Additional fastening is not required, it is enough to lay the slabs tightly over the area of the insulated floor with the lining of the damping tape around the perimeter and proceed with the arrangement of the screed and floor covering.

Designed for roof insulation, including the arrangement of an exploited roof with a cement-sand screed or paving slabs. Plates with dimensions of 1000x600, 1200x1000, 2000x1200, 2400x1200 mm are made with a thickness of 60 to 200 mm, which allows you to install the required thickness of protection in one layer. Distinctive feature Ruf Butts is a two-layer structure. Upper layer 15 mm is made denser than the lower one, this significantly reduces the weight of the plate and facilitates installation.
For fastening, a mechanical method is used with dowels, clamping with a cement screed or adhesive based polyurethane adhesive in case of installation over polymeric waterproofing membranes.
