Our contribution

Part 1

ISOVER glass wool products do not and never did contain asbestos. They are also free from lead, polychlorinated biphenyl (PCB) and mercury.

ISOVER glass wool fibres are not classified under any criteria of the European Regulation. They are exonerated from the carcinogenic classification; this exoneration is regularly checked and certified by the European Certification Board for mineral wool (EUCEB)3. All ISOVER glass wool products are EUCEB certified and RAL certified in the German market.

Under the European Union’s REACH4, ISOVER glass wool fibres are not a Substance of Very High Concern.

  2. Glass wool fibres are exonerated from the carcinogenic classification if they fulfil requirements defined in the Note Q of the European Regulation EC n° 1272/2008. Exoneration criteria refer to the dimensions of the fibres but also to their chemical composition and their bio persistence.
  3. The Mineral Wool industry has initiated a voluntary independent certification scheme (EUCEB) ensuring that all certified products placed in the market are in conformity with all EU regulatory requirements, including bio-solubility. To ensure that fibres comply with the Note Q criteria, all tests and supervision procedures are conducted by independent and qualified experts and institutions.
