LCA & material health results & interpretation MFI® System
Evaluation programs
Declare
Declare labels are issued to products disclosing ingredient inventory, sourcing, and end of life options. Declare labels are based on the Manufacturers Guide to Declare, administered by the International Living Future Institute.
How it works
Material ingredients are inventoried and screened against the Living Building Challenge (LBC) Red List which represents the ‘worst in class’ materials, chemicals, and elements known to pose serious risks to human health and the greater ecosystem.
The Declare product database and label are used to select products that meet the Living Building Challenge's stringent materials requirements, streamlining the materials specification and certification process.

What's in this product and why
Declare level
'Red List Free' is achieved when the product does not contain any ingredients listed on the Living Building Challenge Red List above the 100 ppm (0.01%) reporting threshold, demonstrating full compliance with material health requirements without the need for exceptions.
What's in the product and why
All components of the MFI® system are Red List Free. The Red List, developed by the International Living Future Institute, identifies chemicals and materials known to pose risks to human and environmental health. Eliminating these substances is a key design principle for Knight Wall Systems, and material selection for these systems was guided by that standard.
The isolator and bracket head cap are made with a Red List free thermoset polymer, selected for both its compliance and performance characteristics. This material provides durability and structural reliability without relying on hazardous additives typically found in similar applications.
All metal components in the systems use steel coated with ZAM® (zinc-aluminum-magnesium), which is also Red List free. ZAM® offers excellent corrosion resistance, improving the overall longevity of the system. Steel’s ability to be recycled indefinitely without degrading its properties also contributes to reducing environmental impact over the full life cycle of the product.
What's been done in the design and manufacture in consideration of the potential human health impacts in the use stage
The MFI® system has been designed and manufactured with the intention of causing as little harm to human and environmental health as possible. By using recyclable steel and Red List free materials, the system ensures that end users do not need to be concerned about interacting with the product in either installation or long-term use.
Where it goes at the end of its life
KWS encourages consumers to recycle used rainscreen cladding support systems, which are 100% recyclable. For information on local recycling options, please contact your municipal waste management program.
How we're making it healthier
One way we are reducing the environmental and health impacts of the MFI® system is by focusing on responsible sourcing and material transparency. The steel used in the system is sourced from the USA, which helps reduce transportation-related emissions. Additionally, the steel contains at least 34.2% recycled content, meaning less new raw material is needed. This not only lowers the environmental impact of production but also promotes the use of recycled materials, making the system a more sustainable and healthier choice for both people and the planet.
