What is basalt?
Basalt is a volcanic stone. To be precise: it’s solidified lava, which originates from volcanic eruptions. Our planet provides us with enormous quantities every year. To get an idea of how much basalt is being created: every year, 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.

That means basalt is not only a natural material, but also non-depletable. This makes it a responsible choice, as we’re not exhausting the earth’s valuable resources.
