Features of rockwool brand stone wool. Rockwool insulation technical characteristics: applications and advantages of rockwool light butts insulation High density rockwool basalt slab

Rockwool company produces high-quality thermal insulation that is widely used in a wide variety of areas. Rockwool stone wool is one of the most popular insulation materials. It is environmentally friendly, durable and has a long service life.

A description of ROCKWOOL can start with the fact that insulation is an inorganic and natural product, made using a special technology that involves the fusion of mineral rocks. Materials such as gabbro and basalt are used as raw materials in the production process.

What are the pros and cons of Rockwool? The main purpose is the formation of effective sound and heat insulation structures. High strength of such products is provided by fibers arranged in a chaotic order. One of important features stone wool - its incombustibility. It is made from rocks with a melting point of 1500 ° C.

The scope of use is quite wide: they are used for insulating walls, floors, roofs, internal and external partitions, building facades, as well as for pipes and non-residential structures.

Rockwool specifications:

• height - 1000, 1200 mm;
• width - 500, 600 mm;
• thickness - from 40-2000 mm;
• density from 30 - 210 kg / m3.

The disadvantages of such products include the fact that they often become a habitat for various rodents, therefore, their installation should be treated with particular attention. In addition, there are speculations about the harm from Rockwool basalt wool, since compounds such as formaldehyde and phenol are used in its production. However, if in the process of its manufacture all technological process carried out competently, it is safe for human health and the environment.

Benefits and cost

Basalt Rockwool insulation has many advantages. It is environmentally friendly, safe for health and provides the opportunity to save significant amounts of energy. This material has excellent acoustic properties and good moisture insulating properties.

When describing Rockwool based on stone wool, one cannot fail to note such advantages as durability and resistance to temperature and mechanical stress. In addition, the material is distinguished by good vapor permeability and high strength.

What is the average cost of Rockwool boards? The price of a product largely depends on its brand:

Installation features

According to reviews, Rockwool is considered one of the best products, however, it is necessary to correctly carry out the installation. Rockwool thermal insulation begins with the fact that plates are glued to the prepared cleaned surfaces, which are fixed with special dowels, which provide additional reliability. Then glue is applied to the material, the reinforcing mesh is immersed in it and covered with another layer. The final stage will be painting the walls with decorative plaster.

Last time we talked about ... Today, in continuation of this topic, we will take a closer look at Rockwool insulation: dimensions, characteristics, scope. The entire Rockwool mineral wool line is made from volcanic rock called basalt. Therefore, such insulation is also called basalt or stone wool. The production was founded in Denmark and Sweden in 1937. Since that time, the company has significantly expanded and opened its branches in Europe, Asia, North America. Today it is the most famous brand among mineral wool heaters, the high quality of which is beyond any doubt.

Rockwool thermal insulation in slabs

Thermal insulation in slabs.

Thermal insulation in slabs is used for different types works. Depending on the area of \u200b\u200bapplication, the specifications material. The Rockwool manufacturer provides a wide assortment range so that you can choose the necessary Rockwool thermal insulation, the characteristics of which are optimal for each individual case.

Rockwool insulation, wall ruler dimensions:

• 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. 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 / m. cube and 180 kg / m. cube), which allows you to lower its thermal conductivity. Both materials can be applied with a thin layer of putty. For Rockwool Lamella insulation, the density specifications are somewhat different from the two previous materials and are 90 kg / m. cub.

Thanks to this, Lamella mineral wool is more elastic, it can be used on uneven surfaces. Application of a thin layer of plaster or finishing with clinker tiles is allowed. 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 range is used for facades that are plastered over a metal reinforcement mesh.

The types of insulation that fit into the inter-wall space depend on the wall material - concrete or small-piece materials, for example, brick.

For concrete, Concrete Element Butts is used, it is suitable for both monolithic structuresand for panels. For brick walls, Caviti Butts is used. The density of Rockwool insulation for concrete walls 90 kg / m2 cube, and for brick only 45 kg / m. cub.

Rockwool for roofing

Thermal insulation in plates, laminated with foil.

For the roof, two-layer and single-layer materials are used, the installation of which is carried out with and without vapor barrier films. In addition, there is thermal insulation on which a screed can be poured with a maximum load of 3 kPa. Insulation is also available, which is used in metal sandwich panels for roof installation.

Characteristics of Rockwool insulation for roofs, consisting of two layers:

• marking - Ruf Butts D (Extra, Optima, Standard);
• density of layers - Extra 130/235 kg / m. cube, Optima 120/205 kg / m. cube, Standard 110/180 kg / m. cube;
• thermal conductivity is the same for all and is 0, 037 W / m * C.

The lower the density, the lower the weight of the Rockwool insulation. Single-layer materials are marked with Ruf Butts N (Optima 100 kg / m3 and Extra 115 kg / m3) and Ruf Butts V (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 Ruf Butts Screed with a density of 135 kg / m is used. cub. For the manufacture of sandwich panels, mineral wool Sandwich Butts K (140; 155 kg / m3, 0.045 W / m * C) and Sandwich Butts C (115 kg / m3, 0.042 W / m * C) are used.

Sauna Rockwool

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. Foil beats off up to 95% of IR radiation and performs the function of water protection. The width of Rockwool insulation for saunas is 0.6 m, and the length is 1 m, the density of the material is 45 kg / m. cube, thermal conductivity coefficient of 0.036 W / m * C.

Marked as Tech Butts, presented in five positions with a density of 40 to 140 kg / m. cub. 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. cub.

Rockwool insulation in rolls

Rockwool lamellar rolls.

Types of Rockwool insulation 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 * C. They are used for thermal insulation of highways and technological equipment, can be with foil;
• Wired Mat - 50 kg / m2. cube, stitched with galvanized wire;
• Domrock, Megarock, Multirock.

Lamellar rolls are narrow rectangular parts of thermal insulation that are fixed on a foil base. This approach allows tighter materials to be rolled into rolls. These include Klimafix and Lamella Mat. The dimensions of Rockwool insulation differ only in length and thickness, and the width for all is standard 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 differs, the presence of foiling or reinforcement. 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. Warming of the building and its protection from the summer heat will be related issues here. Quite often, materials based on mineral wool have recently been used as insulation. They allow you to solve the above tasks. 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, they, according to consumers, have many positive features, among which should be highlighted:

• fire safety;
• acoustic comfort;
• environmental friendliness;
• durability;
• ability to keep warm.

Mineral wool when exposed to fire, it will prevent its spread. This sometimes creates suitable conditions for saving people. The fibers are capable of undergoing heating up to 1000 ° C. In case of fire, structures covered with mineral wool can become protective.

With extreme heating, the cotton wool layer does not smoke, and also does not become a source of molten droplets. Rockwool mineral wool, according to buyers, provides acoustic comfort. The boards are capable of absorbing structural, vibration and other noise. The protective layer copes with these tasks more efficiently in comparison with similar materials. The manufacturer managed to achieve this property thanks to the chaotic interweaving of fibers, between which air cavities are formed, communicating with each other.

Why choose "Rockwool"

Mineral wool has been awarded the EcoMaterialGreen safety label, which indicates sustainability. Thermal insulation can be used in buildings for any purpose, even for insulating children's rooms. The product is positive This indicates that the energy saved exceeds the energy cost of production.

Consumers love durability too. It is provided with a special structure that guarantees shape stability and rigidity. You can not be afraid of deformation of the plates, which do not shrink during the entire service life. Buyers especially emphasize that rock wool does an excellent job of keeping warm.

It has a low coefficient of thermal conductivity. 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 a heater with outstanding technical characteristics. For example, the coefficient of thermal conductivity is equal to the limit from 0.036 to 0.038 W / mK. These parameters are among the best among the insulation of the described class. The most commonly used thickness is 50 mm. The web does not shrink even after long-term operation.

The structure is unique, it assumes a chaotic arrangement of fibers. This difference can be highlighted when comparing mineral wool with fiberglass - in the latter, the threads are located almost longitudinally. This quality has a positive effect on stiffness 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 reversed. 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 is not destroyed. Therefore, it can be used even in damp rooms.

Insulation "Rockwool" 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 a positive effect, because condensation does not accumulate during operation, and the walls breathe freely. Insulation is also capable of performing sound insulation functions. The wave, passing through the layer of insulation, dies out, 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 - from the initial volume it can change its size by 30%. Fibers have a certain melting point, so the material under fire conditions will be able to protect structures from fire, inhibiting the process of pore destruction. The insulation starts to melt at 1000 ° C. Insulation "Rockwool" 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

50mm Rockwool mineral wool has a permanent binder among the 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 interior slabs.

A truly exclusive product is Sandik slabs, which are produced specifically for private housing construction. At the final stage, the canvases are compressed, this 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, so installation is quick and easy. Water absorption by volume is 1.5%. The material is transported in a vacuum package, so the consumer does not have to transport air anymore. You will only transport material.

It should be laid horizontally and covered vehicles are recommended for transportation. The described material is manufactured in standard size, which is 800x600 mm. As an example of a 50 mm slab, you can also consider Light Butts, which is specifically designed for lightweight roofing and lightweight structures.

One of the most popular thermal insulation materials on the world market is ROCKWOOL insulation. 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 same name in 27 countries.

Low thermal conductivity of mineral wool

The main function of any heat-insulating material is to create and maintain a comfortable indoor microclimate. What substances best meet this requirement? These are substances with low thermal conductivity. Manufacturers of thermal insulators began to produce mineral wool insulation several decades ago. Mineral wool is the finest fibers compressed by a binder into a web with a thickness of 50 mm to 100 mm.

Today, fiberglass insulation is presented on the market, which contains sand and recycled glass. Stone wool made from basalt rock rocks.

Stone wool

Stone wool is one of the varieties of mineral

Rock wool is produced by melting basalt volcanic rock at a temperature of about 1500 C and simultaneously pulling fibers with the addition of binder components and water-repellent compounds. As a binder, 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 opinion on product safety. Rockwool was one of the first to be awarded the EcoMaterialGreen certification.

Characteristics of Rockwool insulation

Insulation in the package

The peculiarities of production and initial substances 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, the web does not shrink due to the unusual structure and randomly located fibers. This distinguishes it from fiberglass, in which the fibers are located almost longitudinally. It also has a positive effect on material rigidity and tear resistance.
• Due to the mechanical interaction of the fibers with each other, the insulation after vertical installation does not fold under its own weight.
• Thermal conductivity is significantly influenced 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 makes it possible to use it for thermal insulation of wet rooms.
• Rockwool insulation has a high vapor permeability, which is more than 0.25 mg / (mx h x Pa). The insulation is able to pass water vapor and air through itself. Consequently, moisture condensation does not accumulate in structures with ROCKWOOL insulators. The walls and the whole house breathe freely.
• Insulation also works as a soundproofing material. The sound wave, passing through the rockwool layer, attenuates in it, and the sound is absorbed. The overall noise level in the rooms is low.
• The structure of the insulation is such that there are many air pores in it, so it is easily compressed, the compression is about 30% of the original volume.
• The melting temperature of the fibers of the insulation is over 1000 C, therefore, in conditions of fire, the material provides protection against fire of building structures, delays the process of destruction of bearing supports.
• No living organisms can be inside this inorganic material and eat it. This applies to 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 with 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 the food industry, inclusive.

Heaters are produced in the form of plates, rolls for ease of installation in various designs. For example, rigid FACADE BATTS slabs are used for facade insulation, and LIGHT BATTS SCANDIC slabs are used in private construction. "Vapor barrier for roofs, walls, ceilings" is produced in rolls and is used to protect bearing structures from the flow of water vapor.

So, ROCKWOOL products can be divided into several groups:

• Rigid slabs;
• Lightweight 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. Insulation of the Rockwool brand is not inferior to other heat-insulating materials either in its properties or ease of installation, and is one of the most popular insulation materials that are chosen by both professionals and people involved in construction on their own.

Video about stone slab properties

Knowing the properties of a stone slab will help you understand whether it is worth buying just such a heater.

Rockwool stone wool is a natural insulation produced by the well-known international company Rockwool. It is made by fusion of mineral rocks, the main raw materials are gabbro and basalt. In fact, it is an improved type of glass wool that is environmentally friendly and devoid of all the disadvantages. Produced in mats, plates, cylinders. Rockwool products have a number of advantages over the technical characteristics of other types of insulation materials.

The principle of production is similar to the mechanism of creating volcanic rocks during natural processes. Raw materials with the addition of coke are sent to the smelting furnace, where at a temperature of more than 1500 0 С the stone is transformed into liquid lava. The substance is cast into a centrifuge, under the influence of powerful air currents it turns into cotton wool fibers. Binders and water repellents are added to shape to provide the best Rockwool performance. Mats, plates and cylinders are formed from the resulting substance, which, after hardening, acquire the properties of a heater.

Thanks 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 binder, but does not damage the board. The mats can withstand temperatures up to 750 ° C while keeping the surface cool on the other side. Basalt wool of the Acoustic Butts brand reliably protects structures from fire.

Features of thermal insulation

Energy losses occur in areas of concrete floors, at joints, corner surfaces. Rockwool insulation keeps the rooms comfortable, preventing 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 excessive noise is attenuated. For high-quality insulation, it is enough to use products with a thickness of 100 mm. According to consumer reviews, protection against extraneous sounds reaches 60 dB. The fibers in the insulation are arranged randomly, which guarantees high strength characteristics in compression, tension and load, including point load. The mats can withstand pressures exceeding 100 kPa without any risk of deformation or destruction. When used in the arrangement wet facades Rockwool Acoustic Butts basalt wool is placed under the plaster layer, as it has a tensile strength of up to 8 kPA. It is also effective for ventilated external cladding structures. Even with strong gusts of wind, the plates remain in their original shape.

During production, stone wool undergoes a hydrophobization process; its open porous structure is 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 does an excellent job 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 the mats the most popular in protecting rooms from the cold.
