Rock Wool

Rock Wool


Rock Wool is a stable insulation material manufactured from various types of diabase rock, mainly basalt of specific predetermined chemical compositions, which is melted at super high temperature in a technically advanced but simple process. The resulting natural silicate is drum spun at very high speeds to produce 'hair-fine' inert fibres that are bonded together with a special thermosetting resin and impregnated with special additives.
