A naturally renewable resource


  • A natural resource found in abundance around the world, diabase rock is the primary raw material used to manufacture our stone wool products
  • The natural process by which diabase is formed is taking place right now all over the world

Volcanic activity means that nature creates new reserves of diabase rock every year – around 38,000 times more than the entire Rockwool Group extracts.

For more information on the high abundance and renewability of raw materials for stone wool production, view a recent independent article by clicking below.
