Natural and recyclable insulation material


ROCKWOOL stone wool insulation is made from volcanic rock. Stone wool is naturally non-combustible (containing no harmful chemical flame retardants) and will not give off any significant amount of toxic smoke during a fire. 

Additionally, stone wool lasts more than 60 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 made from naturally occurring volcanic rocks like basalt, diabas and gabbro. Stone wool is a highly versatile, non-combustible material that provides industry-leading thermal and acoustic insulation as well as fire protection. It creates a natural and recyclable insulation material.

Key benefits:

  • Natural, made from volcanic rock
  • Non-combustible
  • Flame retardant-free
  • Recyclable
  • Thermally efficient
  • Water repellent yet vapour permeable
  • Mould, mildew and rot resistant
  • Easy to cut and shape
  • Dimensionally stable over time – does not lose its performance traits

Possible replacement to

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