Dunite, a magnesium silicate, is a key raw material in the manufacture of rock wool, where it acts as a source of magnesium. Its special RockAq variety, with a lower moisture content than the standard grade, enhances efficiency in specific production processes.

Thanks to its low melting point, it reduces energy consumption, extends fibre-spinning time, and lowers CO₂ emissions, delivering a more sustainable and competitive process compared with other minerals such as basalt or dolomite. This makes it the ideal choice for the thermal and acoustic insulation industry.
