Durable and recyclable insulation material


ROCKWOOL stone wool insulation is based on volcanic rock. Stone wool is non-combustible which means it can help stop the spread of a building fire and does not contain any chemical flame retardants. In addition, if it is exposed to fire it will not give off any significant amount of toxic smoke. 

Extremely durable, stone wool lasts more than 65 years without any loss of thermal efficiency, non-combustibility or dimensional stability. It can also be endlessly recycled at a growing number of locations, helping to reduce the amount of construction waste going to landfill.  


ROCKWOOL stone wool insulation is based on volcanic rocks like basalt, diabase and gabbro. Stone wool is a highly versatile, non-combustible material that provides industry-leading thermal and acoustic insulation as well as fire protection.

Key benefits:

  • Based onvolcanic rock, one of Earth’s most abundant resources
  • Non-combustible
  • Flame retardant-free
  • Endlessly recyclable
  • Thermally efficient
  • Mould, mildew and rot resistant
  • Easy to cut and shape
  • Dimensionally stable over time, with no loss in performance traits

Possible replacement to

Combustible plastic foam insulation types that often require chemical flame retardants to meet fire safety standards.
