The mineral wool consists of extremely thin, randomly interwoven fibers, between which there is air, which provides them with a small density (from 30 to 200 kg/m3). This provides them with a low thermal conductivity (from 0.035 to 0.042 W / (m * K)). The lower thermal conductivity - the better the insulating properties of the material. The mineral wool brand reduces heat loss in winter and protect you and your home from heat in summer.
The main component for the production of mineral wool is 100% natural, environmentally friendly material basalt. Its melting point is about 1,500°C. These thermal insulation products satisfy the most stringent fire safety requirements and can be used as fire insulation and fire protection systems.
Mineral wool is safe in installation and operation, does not contain asbestos impurities. It has a very low emission of dust particles and chemicals. All products have passed the appropriate hygienic control and certification.
Rock wool has a high level of sound absorption.
Slabs of the mineral wool possess such strength characteristics that allow to use them in different systems and to ensure consistent quality, reliability and durability of these systems. All the marks of slabs have been tested, they have the necessary technical certificates and certificates confirming the specifications declared by the manufacturer.
Basalt wool has a high resistance to organic substances. No solvents or alkaline or mildly acidic environment have an impact on it. Under the conditions of normal humidity mineral wool does not cause corrosion.
Slabs are produced on a modern production line of Czech machinery company «Frydlantske Strojirny — Rasl a syn s.a.» using the technology of dry forming from mineral wool and synthetic binding agent with waterproofing modifyingagent.
Thermal insulation materials are the most effective in the dry state. Even a small amount of soaking water has deteriorated the thermal characteristics of insulating materials. Mineral fibers of wool in their nature have water-repellent properties. Moreover, in the process of the production of wool water-repellent additives are added, thus expanding the boundaries of the material usage and to make its installation in a variety of climatic conditions. The moisture content in the rock wool under normal operating conditions is less than 0.5 percent of the units of weight. Compared to many other materials, mineral wool is highly vapor permeable. Mineral wool insulation slabs are good in passing steam and they almost always stay dry, which in its turn affects the healthy microclimate in the building – on the one hand and durability - on the other.
Mineral wool slabs are not subjected to shrinkage and thermal movement. Insulation keeps its geometrical dimensions for the entire period of operation. If necessary, mineral wool of low density can be cut with a knife, and denser one – by using a hacksaw.
The term of service of rock wool for more than 70 years.
