FIBRAN geo Flexible Stone wool insulation board is industrially produced from molten rock spun into fibers. It is classified as mineral wool product for use in building insulation, according to the European Standard EN 13162 (MW - Mineral Wool insulation products). Stone wool is a natural inorganic fibrous material, widely recognized for its thermal and sound insulating properties, as well as its excellent performance towards fire protection. FIBRAN geo is produced from mineral rock, initially fused in an electric furnace at 1520°C and then spun into fibers. The loose stone wool fibers, with the addition of adhesive resin, oil and special silicon compounds that provide hydrophobicity, become cohesive, elastic, non-hygroscopic and water-repellent, formed in boards and finally shrink-wrapped in PE film in packages. The non-use of fossil fuels (e.g. coke) as a main production fuel minimizes polluting gas emissions in the environment
