Production of basalt

The earth produces 38,000 times more basalt through volcanic activity than the ROCKWOOL Group, of which we are part, uses for the production of stone wool

High melting point

We bring together the basalt and recycled content and heat it to a temperature of 1500 °C, and then it’s melted and whipped around by a spinning machine. After the stone wool is done, we add a small amount of binder and press it into a high-density board.

Stone wool, made from basalt, is the core material for our facade boards
