Is there any cancer risk from the fibres of rock wool?
• The International Agency for Research on Cancer (IARC) — part of the World Health Organisation — in October 2001 carried out a review of man-made vitreous fibres concluded that mineral wool insulation was ” unclassifiable as to its carcinogenicity to humans”. The safety of mineral wool insulation fibres is now beyond doubt and mineral wool insulation fibres should be cleared of any suspicion of carcinogenic effect, and removed from IARCs list of suspected carcinogenic agents.
