KNAUF Insulation has announced it has become the first manufacturer in Europe to achieve a DECLARE ‘Red List Free’ label for rock mineral wool products.
The manufacturer’s unfaced rock mineral wool range, made with ECOSE Technology, has received the label. This follows ‘Red List Free’ accreditation for its entire glass mineral wool range in 2021.
Knauf explained that the DECLARE label allows architects and specifiers to see what is in a product to help them make informed choices. It includes a ‘nutrition-style’ list of ingredients, and whether it contains chemicals featured on the DECLARE ‘Red List’ – substances designated as harmful to health and the environment, such as added formaldehyde. It also includes information about where a product comes from.
“We know that the industry is increasingly asking the right questions about the environmental impact of construction products,” said Luke Davies, product manager – rock mineral wool at Knauf Insulation. “These DECLARE labels provide transparency and clear information so that those using or selling our products have a clear understanding of the ingredients that constitute them.
“They complement the comprehensive Environmental Product Declarations we already publish for each of our product ranges.”
The use of ‘Red List Free’ products is already a factor in achieving credits in Green Building Rating Systems such as LEED and the Well Building Standard. Knauf said this means the DECLARE label can be used by architects, housebuilders and installers to support their own sustainability and health and safety credentials.
To achieve the DECLARE label for its unfaced rock mineral wool range, Knauf Insulation has disclosed the composition of the products, which mainly consists of volcanic rock, typically basalt and dolomite, with around 35% recycled content.
The following products have been certified DECLARE ‘Red List Free’:
- Rocksilk® Acoustic Floor Slab
- Rocksilk® Acoustic Floor Slab Plus
- Rocksilk® Building Slabs (excluding any with additional facings)
- Rocksilk® Flexible Slab
- Rocksilk® RainScreen Slab
- Rocksilk® RainScreen Slab 455
Knauf Insulation also received a DECLARE ‘Red List Approved’ accreditation for its Rocksilk® RainScreen Slab with Black Glass Veil.
