European Certification Board of Mineral Wool Products

All glasswool products manufactured by Knauf Insulation are made of non-classified fibres (fibres that are less bio-persistent than every day dust) and are certified by EUCEB. EUCEB, European Certification Board of Mineral Wool Products - www.euceb.org, is a voluntary initiative by the mineral wool industry. It is an independent certification authority that guarantees that products are made of fibres, which comply with the exoneration criteria for carcinogenicity (Note Q) of the Regulation (EC) 1272/2008.To help user’s identify the safety of our glasswool fibres the EUCEB logo is displayed on our product packaging and/or labels.

Declare Recognition

Our entire Glass Mineral Wool product range has been awarded the DECLARE 'Red List Free' label.

Whether you are specifying or installing, DECLARE aims to show you that our Glass Mineral Wool range of products is insulation that you can trust. This is demonstrated in a similar way to that of food nutrition labels. The DECLARE label shows clear and transparent details such as:

  • Where a product comes from,
  • What it's made of,
  • Whether it contains chemicals featured on the DECLARE ‘Red List’. These are substances to avoid because they could be harmful to health and the environment.

To achieve the DECLARE label, we’ve gone through rigorous testing and disclosed the entire composition of our Glass Mineral Wool products down to 0.01%. Our Glass Mineral Wool range is manufactured with up to 80% recycled content and the remaining percentage composed entirely from Red List Free raw materials.

DECLARE also contributes to green building rating systems such as LEED and WELL. This means you can use Knauf Insulation Glass Mineral Wool products to deliver buildings that are proven to be healthy and good for the environment.

Through our participation in the DECLARE label scheme, architects, house builders and installers can verify their own sustainability and health and safety credentials too.
