Declare ‘Red List’ Free is a third party accreditation and is similar to a food nutrition label but for building products; it’s a straightforward ingredient list and allows product transparency disclosure because it identifies where a product comes from and what it’s made of.


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.


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. Our rock mineral wool products are manufactured using around 35% recycled content (recycled material mostly from the steel industry along with customer production waste).


The use of ‘Red List Free’ products is already a key factor in achieving credits in Green Building Rating Systems such as LEED and the Well Building Standard. This means the Declare label can be used by architects, housebuilders and installers to support their own sustainability and health and safety credentials.
