The idea of producing stone wool was fostered on Hawaii. After volcanic eruption on the islands the natives found woolen strings of stone lying on the ground. They thought it was hair from their goddess, Madame Pele, that the temperamental lady had torn out in her rage.

Today we know that stone wool is much more than that. We have discovered the unique qualities of the material that makes it perfectly suited for a wide range of purposes.

That is why the Rockwool Group has tried to imitate the Hawaiian goddess for more than 70 years now.

The Rockwool Group has spent more than 60 years trying to improve the stone wool production process.

In the beginning everything was done manually, from the trusted employee who shoveled the approximately right amounts of raw material into the furnace and to the people wrapping up the final product.

Today a highly sophisticated machinery ensures the quick and steady production of a superior stone wool quality.
