Rock wool (sheet rock) is an insulating material obtained from diabasic igneous rocks, basalt, and dolomite, with adhesives added; it naturally has an excellent thermal insulation capacity and good sound-absorbing properties.

Rock wool does not absorb any water or moisture, and also has excellent fire behaviour: it does not contribute to the development or the spread of fires. Available in rolls or panels, in thicknesses ranging from 3 cm to 20 to 200 mm and densities from 40 Kg/mc up to 165 kg/mc.

Used for cladding, ventilated roofs, flat roofs, and REI walls.
