Last time we talked about . Today, in continuation of this topic, we will take a detailed look at Rockwool insulation: dimensions, characteristics, scope of application. The entire Rockwool line of mineral wool is made from a volcanic rock called basalt. Therefore, such thermal insulation is also called basalt or stone wool. Production was established in Denmark and Sweden in 1937. Since then, the company has expanded significantly and opened its branches in Europe, Asia, North America. Today it is the most famous brand among mineral wool insulation, in high quality which there is no doubt about.
Rockwool thermal insulation in slabs
Thermal insulation in slabs.
Thermal insulation in slabs is used for various types works Depending on the scope of application, the technical specifications material. The manufacturer Rockwool provides a wide range of products so that you can select the necessary Rockwool thermal insulation, the characteristics of which are optimal for each individual case. Moreover, each of the insulation materials is quite universal. The boards are used for thermal insulation:
- walls;
- roofs and horizontal ceilings.
- saunas;
There are also materials with improved soundproofing qualities.
Rockwool for walls
Rockwool insulation, ruler dimensions for walls:
- width 0.5 m or 0.6 m;
- length 1 m or 1.2 m;
- thickness from 2.5 cm to 18 cm.
There is a slight difference between these Rockwool insulation materials. Technical characteristics Butts and Butts D differ in the density of the material. The first has a uniform density of 130 kg/m. cube, and the second consists of two layers (94 kg/m3 and 180 kg/m3), which makes it possible to reduce its thermal conductivity coefficient. A thin layer of putty can be applied to both materials. For Rockwool Lamella insulation, the density specifications are slightly different from the two previous materials and amount to 90 kg/m. cube
Thanks to this, Lamella mineral wool is more elastic, it can be used on uneven surfaces. It is allowed to apply a thin layer of plaster or finish with clinker tiles. Venti Butts is used for ventilated facades, the installation of which is allowed without the use of wind protection. There are only four varieties of this line. The Plaster Butts line is used for facades that are plastered over a metal reinforcing mesh.
The types of insulation that are installed in the inter-wall space depend on the wall material - concrete or small-piece materials, for example, brick.
Concrete Element Butts is used for concrete; it is suitable for both monolithic structures and panels. For brick walls used by Cavity Butts. Density of Rockwool insulation for concrete walls 90 kg/m. cube, and for brick ones only 45 kg/m. cube
Rockwool for roofing
Thermal insulation in slabs, laminated with foil.
For roofing, two-layer and single-layer materials are used, the installation of which is carried out with or without vapor barrier films. In addition, there is thermal insulation onto which screed can be poured with a maximum load of 3 kPa. Insulation is also produced, which is used in metal sandwich panels for roofing.
Characteristics of Rockwool insulation for roofs, consisting of two layers:
- marking – Roof Butts D (Extra, Optima, Standard);
- layer density – Extra 130/235 kg/m. cube, Optima 120/205 kg/m. cube, Standard 110/180 kg/m. cube;
- The thermal conductivity is the same for all and is 0.037 W/m*C.
The lower the density, the less weight of Rockwool insulation. Single-layer materials are labeled Roof Butts N (Optima 100 kg/m3 and Extra 115 kg/m3) and Roof Butts B (Optima 160 kg/m3 and Extra 190 kg/m3). The thermal conductivity of a material with a higher density is slightly higher - 0.04 W/m*C versus 0.036 W/m*C. Under the screed layer, a single-layer material Roof Butts Screed with a density of 135 kg/m is used. cube For the manufacture of sandwich panels, mineral wool Sandwich Butts K (140; 155 kg/m3, 0.045 W/m*C) and Sandwich Butts S (115 kg/m3, 0.042 W/m*S) are used.
Rockwool for sauna
Thermal insulation in rolls with foil (can be without foil).
For saunas and baths, Rockwool Sauna Butts mineral wool is used, which is glued with foil on one side. The foil repels up to 95% of IR radiation and performs the function of water protection. The width of Rockwool insulation for saunas is 0.6 m, the length is 1 m, the density of the material is 45 kg/m. cube, thermal conductivity coefficient 0.036 W/m*S. Fire Batts can also be used for steam rooms, the main purpose of which is to insulate fireplaces. The material can be with or without foil, it can withstand high temperatures, density 100 kg/m. cube, thermal conductivity 0.041 W/m*S. If used for its intended purpose, you must adhere to the installation rules. In the fireplace, the cotton wool is placed no closer than 4 cm to the firebox body, and the shiny side should face inward.
Soundproofing Rockwool
The Rockwool line with enhanced soundproofing characteristics is represented by four positions, which differ in their density:
- Acoustic Butts – 45 kg/m. cube;
- Acoustic Butts PRO – 60 kg/m. cube;
- Floor Butts – 125 kg/m. cube;
- Floor Butts I – 150 kg/m. cube
Technical insulation Rockwool
The materials are used for insulation of equipment, heating and water pipes, air ducts, industrial furnaces, and various tanks. Applies everywhere except food industry. They are labeled as Tech Butts and are presented in five positions with a density from 40 to 140 kg/m. cube For communications, in addition to mats, winding cylinders are used. Let us dwell separately on . The work is mainly carried out from the outside, but there are precedents when it is necessary internal insulation. For this, Rockwool Industrial Batts 80 with a density of 80 kg/m is used. cube
Rockwool insulation in rolls
Rockwool lamella rolls.
Types of Rockwool insulation in rolls are divided into two categories:
- solid;
- from lamellas.
Solid rolls are long strips of insulation without joints. They are presented in a line called:
- Tech Mat – 43 kg/m. cube, 0.034 W/m*S. Used for thermal insulation of pipelines and technological equipment, can be with foil;
- Wired Mat – 50 kg/m. cube, stitched with galvanized wire;
- Domrock, Megarock, Multirock.
Lamella rolls are narrow rectangular pieces of thermal insulation that are attached to a foil base. This approach allows you to roll denser materials. These include Klimafix and Lamella Mat. The dimensions of Rockwool insulation differ only in length and thickness, and the standard width for all is 1 m.
Regardless of whether Rockwool thermal insulation is produced in mats or rolls, the entire line is quite versatile. The main characteristics are approximately the same, only the density of the material and the presence of foil or reinforcement differ. There are also two-layer and single-layer insulation, of course, different sizes.
If you strive to live in peace and comfort, then, like many others, you must be trying to protect your home from extraneous noise. Related issues here will be the insulation of the building and its protection from the summer heat. Quite often, mineral wool-based materials have recently been used as insulation. They allow you to solve the problems described above. In general, the category “mineral wool”, according to state standards, includes products that are classified into several varieties, among them: glass and slag wool.

Reviews
The products described are quite competitive; according to consumers, they have many positive features, among which the following should be highlighted:
- fire safety;
- acoustic comfort;
- environmental friendliness;
- durability;
- ability to retain heat.
Mineral wool when exposed to fire will prevent its spread. This sometimes makes it possible to create suitable conditions for saving people. The fibers can undergo heating up to 1000 °C. In the event of a fire, structures covered with mineral wool can become protective.
When exposed to extreme heat, the layer of cotton wool does not smoke and does not become a source of molten droplets. Rockwool mineral wool, according to buyers, provides acoustic comfort. The slabs are able to absorb structural, vibration and other noise. The protective layer copes with these tasks more effectively compared to similar materials. The manufacturer managed to achieve this property thanks to the chaotic interweaving of fibers, between which air cavities are formed that communicate with each other.
Why choose Rockwool
Mineral wool has been awarded the EcoMaterialGreen safety mark, which indicates environmental friendliness. Thermal insulation can be used in buildings for any purpose, even for insulating children's rooms. The product has a positive This indicates that the energy saved exceeds the energy costs of production.
Consumers also like durability. It is provided by a special structure that guarantees dimensional stability and rigidity. You do not have to worry about deformation of the slabs, which do not shrink during their entire service life. Buyers especially emphasize that mineral wool does an excellent job of retaining heat.
It has a low thermal conductivity coefficient. The material can be compared to a wall made of timber. The same amount of heat will pass through a 100 mm layer of insulation and a 440 mm layer of timber. These parameters can be compared with brickwork, the thickness of which reaches 1960 mm.
Specifications
Rockwool mineral wool is an insulation material that has outstanding technical characteristics. For example, the thermal conductivity coefficient is equal to the limit from 0.036 to 0.038 W/mK. These parameters are among the best among the insulation materials of the described class. The most commonly used thickness is 50 mm. Shrinkage of the canvas does not occur even after prolonged use.
The structure is unique; it involves a chaotic arrangement of fibers. This difference can be identified when comparing mineral wool with fiberglass - in the latter, the threads are located almost longitudinally. This quality has a positive effect on rigidity and tear resistance. The fibers interact with each other, so the insulation, even when installed vertically, does not fold under its own weight.
Rockwool affects thermal conductivity. The relationship between mass and volume is inverse. The lower the density, the higher the thermal conductivity will be. The mentioned characteristic is equal to the limit of 35-37 kg/m 3. During the production process, the material is treated with water-repellent oils; they provide hydrophobicity, which is expressed in the ability not to absorb, but to repel moisture. This feature can be called unique, because in a humid environment the material does not collapse. Therefore, it can be used even in damp rooms.
Rockwool insulation has a fairly high vapor permeability, it is 0.25 mg/(m·h·Pa). Thermal insulation allows air and steam to pass through. This gives positive effect, because condensation does not accumulate during operation, and the walls breathe freely. The insulation can also perform sound insulation functions. The wave, passing through the insulation layer, is attenuated, and sound is absorbed.
Compressibility and bioinertness
The structure of the insulation is unique and has many air pores, so the material is easily compressed - it can change its size by 30% from its original volume. Fibers have a certain melting point, so in the event of a fire, the material will be able to protect structures from fire, inhibiting the process of pore destruction. The insulation begins to melt at 1000 °C. Rockwool insulation is also good because it is not capable of becoming a suitable environment for the life of living organisms. This applies not only to bacteria, but also to small rodents.
50 mm insulation
50 mm Rockwool mineral wool has a durable binder among its ingredients. The material is used for thermal insulation of pipes, roofs and walls. It can become part of construction and engineering industrial buildings, office premises and residential buildings. Insulation can be used for internal floors.
A truly exclusive product is Sandik slabs, which are produced specifically for private housing construction. On final stage The canvas is subjected to compression, which saves space during transportation. The material is compressed by 60%.
The thermal conductivity of Rockwool mineral wool is quite low. The edges of such products can spring back, so installation is quick and simple. Water absorption by volume is 1.5%. Transportation of material is carried out in vacuum packaging, so the consumer will no longer have to transport air. You will transport only material.
It should be laid horizontally, and covered vehicles are recommended for transportation. The described material is manufactured in standard size, which is equal to 800x600 mm. As an example of a 50 mm slab, you can also consider “Light Butts”, which is specially designed for lightweight roofing coverings and lightweight structures.

Stone wool Rockwool is a natural insulation material produced by the well-known international company Rockwool. It is made by fusing mineral rock, the main raw materials are gabbro and basalt. In fact, this is an improved type of glass wool, which is environmentally friendly and free of all disadvantages. Available in mats, slabs, cylinders. Rockwool products have a number of advantages compared to the technical characteristics of other types of insulating materials.
The production principle is similar to the mechanism of creation of volcanic rocks during natural processes. Raw materials with the addition of coke are sent to a smelting furnace, where at a temperature of more than 1500 0 C the stone is converted into liquid lava. The substance is cast into a centrifuge and, under the influence of powerful air currents, turns into cotton wool fibers. To give shape, binders and water-repellent additives are added to ensure best characteristics Rockwool. The resulting substance is used to form mats, slabs and cylinders, which, after hardening, acquire the properties of insulation.
Due to the manufacturing process, Rockwool products are non-flammable. Even with an open fire, cotton wool does not emit harmful substances. The flame can burn out the binding component, but does not violate the integrity of the slab. The mats can withstand temperatures up to 750°C, while their surface on the other side remains cool. Acoustic Butts brand basalt wool reliably protects structures from fire.
Features of thermal insulation
Energy losses occur in areas of concrete floors, at joints, and corner surfaces. Rockwool insulation maintains comfort in rooms, preventing the occurrence of cold bridges. In any house or apartment there is a constant process of steam formation. Permeability is the main advantage of mats. They successfully cope with condensation and remove excess moisture from rooms. The parameter is 0.25-0.3 kPa.
Basalt wool from the Rockwool Acoustic Butts series has a porous structure, due to which excess noise is reduced. For high-quality insulation, it is enough to use products with a thickness of 100 mm. According to consumer reviews, protection from extraneous sounds reaches 60 dB. The fibers in the insulation are arranged randomly, which guarantees high strength characteristics under compression, tension and load, including point loading. The mats can withstand pressures of more than 100 kPa without the risk of deformation or destruction. When used in construction wet facades basalt wool brand Rockwool Acoustic Butts is placed under the plaster layer, as it has a tensile strength of up to 8 kPa. It is also effective for ventilated structures for external cladding. Even with powerful gusts of wind, the slabs remain in their original shape.
During manufacturing, stone wool undergoes a hydrophobization process, its exposed porous structure very resistant to moisture. The water absorption coefficient is 1.5%. When wet, the insulation does not lose its insulating properties. Judging by customer reviews, it copes well with its functions on internal and external surfaces, on the foundation and roof.
The main property of cotton wool - energy conductivity with a value of 0.035-0.045 W/mK makes mats the most popular for protecting rooms from the cold.
Where is it used?
There are several brands of Rockwool stone wool. Each type is designed for specific functions and is mounted on different designs buildings:
1. Insulation for roofing under PVC membrane – Dachrock Prof, Dachrock Max. Designed for flat roofs who have special requirements. For daily maintenance of equipment: solar power plants, wind systems.
2. Fasrock-L and Fasrock Max are suitable for basement floors, ceilings over garages, for cladding facades and frame structures external walls.
3. Rockwool slabs of the Rockton and Panelrock brands are made for partitions, multi-layer walls, ventilated systems for low buildings. According to customer reviews, mats are effectively used in insulating private houses.
4. Megarok, Superrock, Domrock insulation is mounted on suspended ceilings, also brands are intended for attics, attics, ventilated spaces under the roof and pitched roofs with wooden floors. Used for arranging floors on joists.
5. Rockwool is a universal heat and sound insulation, which includes a group of materials: basalt wool of the Acoustic Butts, Light, Flor, . These brands are intended for installation indoors, for finishing walls, floors, ceilings and partitions. These types are especially effective when installed in children's rooms and home theaters.
Review of opinions
Thanks to the peculiarities of production and the use of unique technologies, cotton wool has a large number of positive qualities, with virtually no disadvantages. This can be judged by reviews of Rockwool insulation:
“I did insulation at home last year. I decided to buy the Rockton brand from the manufacturer Rockwool, since it needed to be mounted on a frame. I liked that the packaging was compact and hermetically sealed. They are easy to install, the products are homogeneous, without foreign inclusions. One side is a little tighter, which is convenient for fixing. When working, they simply adjust and do not deform when you cut them. The main functions are performed perfectly - the house is warm and cozy.”
Arkady Zaitsev, St. Petersburg.
“To insulate the roof, we decided to purchase Rockwool Dachrock Prof products, since we have installed solar collector, requiring regular maintenance. Played a role in the selection positive reviews consumers. We completely agree with the opinion about the improved qualities of thermal insulation. The plates don't let through cold air, strong enough, do not deform under loads, precipitation and strong gusts of wind.”
Elena, Moscow.
“I work for a construction company, so in the process I study the characteristics different types isolation. Based on own experience and customer reviews, I decided to buy Rockwool Acoustic for finishing the rooms. I installed mats in the nursery and tiled the basement, as there is a home theater and billiards there. The sound insulation is excellent, there is no dampness, and condensation does not collect. In the future I plan to insulate the facade and roof.”
Vladimir Semin, Krasnodar.
“We bought Rockwool for our dacha and chose the Light brand for finishing interior walls. The material has a reasonable price and excellent characteristics. There have been no problems for two years now comfortable accommodation in the house even in severe frosts. Thermal insulation practically does not allow cold to pass through. You also don’t have to worry that the walls will get damp in our absence, the slabs are resistant to moisture, and mold no longer appears. In addition, there was good noise absorption, even with loud music outside, the room is quiet.”
Anna, Samara.

Preface. Insulation of buildings allows you to reduce the cost of heating premises, create a comfortable microclimate inside and increase the operating life of all load-bearing structures Houses. The use of Rockwool mineral wool is a simple and accessible technology for many, thanks to which effective insulation can be achieved. Let's take a closer look at the technical characteristics of Rockwool insulation.
Rockwool technology, technical characteristics
Rockwool is an ecological material that is obtained by melting rocks and stretching them into thin threads impregnated with a binder. The result is stone wool with a fibrous structure. The production technology allows us to produce strong, moisture-resistant and easy-to-handle slabs 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 ensures non-flammability and guarantees increased strength of products under the Rockwool brand. There are two factories of the company in Russia - in 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 premises - ceilings, floors, partitions, house facades. 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
The Rockwool company produces a wide range of products in the form of rolls and plates. The following types of thermal insulators are in greatest demand today: “Light Butts”, “Facade Butts” and “Acoustic Butts”. Rockwool mineral wool has different technical characteristics, and depending on them, the slabs are used inside or outside buildings. The main characteristics include:
Thermal conductivity. Rockwool mineral wool has the best indicator among its 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 ensures maximum energy efficiency of a residential building.
Flammability(fire resistance). Stone wool belongs to the class 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.
Resistance to deformation is ensured by a chaotic arrangement of the finest fibers, ensuring their dense weaving, rigidity and stability of the shape of the mats. Facade Butts mats are used as thermal insulation for facades - they are dense and rigid, resistant to deformation. In addition, Flexi mats have a springy edge on the long side of the slab.
Vapor permeability. Hydrophobicity and vapor permeability determine the ability of a material to absorb and repel water, as well as allow air to pass through. If you do not provide a vapor barrier when installing the insulation, the thermal insulation qualities will begin to decrease as moisture is absorbed. Waterproof Light Butts mats are used in lightweight structures as a non-load-bearing layer.
Soundproofing. The ability of the material to protect the room from noise is excellent. Between the fibers of the material there is a layer of air that traps all sounds. The degree of sound insulation is influenced by the density and porosity of the Rockwool insulation structure. Sound-absorbing mats Acoustic Butts provide sound-absorbing capacity (within 43-62 dB).
