Rockwool is a mineral wool made from molten basalt and limestone rock that is spun into fibres and then compressed into cubes, blocks or slabs.
Care should be taken when handling rockwool by wearing gloves and mask. The rockwool fibres can cause irritation to the skin, and if breathed in they can also irritate the lungs.
