Warming of constructed and rebuilt buildings can reduce the cost of their heating, create a comfortable living environment, as well as extend the life of bearing structures. The simplest and most affordable option is the use of Rockwool Standard mineral wool. Due to the versatility of this unique material, it is possible to solve all the tasks.
Technology Description
The raw materials for the production of insulation products Rockwall Standard Butts are rocks of the basalt group, which is widespread in nature. These minerals are mined in a cheap, open-pit manner, allowing them to be obtained in large volumes. The cost of the manufactured material is low. The production process of basalt mats Rockwall Standard is as follows:
- After technological preparation, the raw material is loaded into special furnaces, where at a temperature of 1500 ° C it acquires the form of a liquid molten mass.
- The resulting melt is sent to high-speed centrifuges and sprayed onto the finest trickles under the influence of centrifugal forces.
- Thin and long fibers with a length of up to 5 cm and a diameter of 15 μm harden, forming a kind of “carpet”.
- The resulting structure is treated with binders and hydrophobic compounds.
- This is followed by the stage of pressing blanks with imparting the required parameters for the density of Rockwool insulation, after which the resulting mats are further processed at high temperatures.
- At the end of the production cycle, they are cut into standard blocks with further transfer for packaging.
As a result of these procedures, ready-to-use mats of a given size, consisting of the finest basalt fibers, are obtained.
In the chaotic interweaving of threads there is a huge number of cavities filled with air. Due to this structure, the finished basalt material acquires unique thermal insulation characteristics.
Specifications
Rockwool has been producing insulation material for many years, represented by a line of models designed in the form of rolls and plates. The most popular are Light Butts, Facade and Acoustic. The main technical characteristics of Rockwool insulation include:
- thermal conductivity and density of the material;
- fire resistance;
- resistance to deformation;
- vapor permeability;
- soundproof properties.
Rockwool Standard mineral wool has the highest thermal conductivity among known analogues, amounting to 0.036-0.038 W / m K. The efficiency of thermal insulation of structural elements depends on this parameter. Fire resistance is one of the defining characteristics of basalt, due to which stone wool can withstand temperatures up to 1000 degrees. When ignited, it practically does not emit smoke and does not spread fire.
The hydrophobicity and vapor permeability of the insulation determine its ability to absorb or repel moisture, as well as let air pass through the fibers. In the absence of a protective vapor barrier layer, the thermal insulation properties of the material drop sharply as moisture is absorbed into it.
Light Batts waterproof products, for example, are widely in demand in lightweight constructions as a well-protected insulation layer.
Sound insulation or noise protection is achieved due to the presence of an air gap between the fibers, which absorbs sound waves well. This indicator is directly related to the density and porosity of the structure of Rockwool insulation mats.Well-known products of the Acoustic Butts brand guarantee sound absorption in the range of 43-62 dB.
Density and dimensions of plates
Rockwool insulation density determines its resistance to deformation loads and durability. These qualities can be achieved due to the random arrangement of thin fibers, ensuring their strong plexus. This structure gives the mats a special rigidity and shape stability. For this reason, Facade Butts plates are used for thermal insulation of the front parts of buildings. For the same reason, Flexi brand basalt mats have springy edges on one side.
In Rockwool products, the dimensions of the plates are strictly standardized and take values from the standard series. For samples of the Facade Butts, they are represented by the following set of typical values:
- length of a standard plate - 500/600 mm;
- its width is 1000 mm;
- the thickness of the workpiece is 25, 30-180 mm.
The last size of Rockwell insulation varies depending on the specific product sample. One of the possible modifications for this indicator is represented by the Rockwool Standard 50 mm product.
Thermal Insulator Benefits
Rockwool basalt cotton wool successfully competes with the best samples of organic heaters. Compared with them, it has the following advantages:
- ecological purity of the raw materials and the entire process of processing and manufacturing of the final product;
- good thermal conductivity;
- minimizing binders harmful to humans;
- excellent sound-absorbing properties;
- impermeability, defined as hydrophobicity;
- the impossibility of reproduction of parasitic microflora, rodents and harmful insects.
One of the key advantages of the material is fire safety, in terms of which it surpasses well-known synthetic analogues.
The use of insulation
Rockwool Butts product samples relate to the marketable insulation materials used for various purposes. Depending on the modification, the heat insulator is used to protect walls, roofs or provides the desired level of sound insulation. Each of these applications deserves special consideration.
For walls
Especially often products from Rockwool are used for insulation using the technology of a ventilated facade. This approach allows you to optimize the steam exchange and eliminates the possibility of wet walls. Thanks to this, you can choose a decorative facade coating at your discretion.
Membranes for walls of high thermal conductivity are available in two versions:
- regular (with a green mark on the package);
- with the addition of flame retardants to prevent accidental fires (black mark with an orange stripe).
Otherwise, the characteristics of the varieties of membrane insulation practically do not differ from one another.
For the roof
To insulate the roofs of houses being built, the Rockwool Ruf Butts model is provided in the company's assortment. The composition of this series includes basalt slabs of mineral wool insulation with a high rate of rigidity and thermal conductivity.
For all other characteristics, they are also not inferior to traditional protective materials.
Rockwool Ruf Butts brand products are also intended for the arrangement of roofing thermal insulation coatings using technologies that do not involve the use of cement screed.
For the sauna
Rockwool manufactures products designed for saunas and saunas. They are represented by samples of Sauna Butts, which are in high demand and have a low price.Basalt cotton wool for a bath is an effective insulation product, characterized by the following advantages:
- low specific gravity;
- increased heat resistance;
- good thermal conductivity.
The use of this insulator allows you to save on energy - electricity and wood.
Soundproofing Rockwool
Rockwool Acoustic Butts insulation is used for the following purposes:
- for insulation of frame partitions and decorative cladding;
- when finishing floors;
- for the purpose of additional sound insulation of ceiling structures.
These products comply with the standards for sound absorbing materials.
