In Russia, with a difficult climatic conditions became popular method of insulating sandwich, where the insulating materials are a special multi-layered manner. Inside are aerated concrete blocks, and mineral cotton – mid-insulation, then foam, penofolgirovannye materials, finally, the outer layer is applied facing brick. The method makes it possible to optimally sandwich to keep warm, and in addition extends the use of the building. Mineral plates are made from natural ingredients, or rather of basalt and porphyrite. Just used in the production of basalt and porphyrite can achieve the level of 1.8 Module acidity of mineral wool. Thanks to an innovative oxygen injection process, which is used in the manufacture of basalt slabs, the temperature of the source material reaches a half thousand degrees Celsius, which is is a measure of viscosity and dynamic properties of the melt, which determine the quality of the material.
The durability of mineral wool is provided through the use of basalt rock, making stuff also resistant to external influences and can maintain its distinctive character for quite some time. The service life of mineral wool which has – at least 50 years. The level of thermal conductivity of the solid framework is the main component, which depends on the orientation and geometry of the fibers in space. Moreover, these conditions also affect the strength of mineral wool. At a certain density using mineral wool with a randomly positioned and oriented fibers are best. Strength of the material increases with an increase in the number of fibers in a vertical position – therefore, the percentage of these fibers is higher, the lower level with density mineral wool can be used to provide the desired strength. In this regard, the most advanced area of technology boards is just those that are able to make the largest percentage fibers arranged vertically. It is because mineradlnaya wool is now recognized dliderom among modern insulating materials in home construction.
