LCA & material health results & interpretation Jet Stream® ULTRA

Evaluation program


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.

Assessment scope and results


Inventory threshold: 100 ppm

Declare level:

The Declare product database and label are used to select products that meet the LBC's stringent materials requirements, streamlining the materials specification and certification process.

LBC Red List Free This product does not contain any ingredients on the LBC Red List.

LBC Compliant This product meets the requirements of the LBC Red List Imperative due to a temporary exception.

Declared This product has voluntarily self-disclosed all ingredients in order to promote transparency.

What's in this product and why

Declare level

Jet Stream® Ultra contains no Red List chemicals. The Red List is a list of chemicals that are not allowed in Living Building Challenge buildings. Being Red List free is our design benchmark at Knauf. 

Jet Stream Ultra is designed to be blown into walls and attics. This product works well in interiors, as it is virgin glass with a small amount of lubricant. The product meets GreenGuard Gold criteria and is validated to be formaldehyde-free. 

What's in the product and why

The fiber comprising Jet Stream Ultra is 98 – 99% inert virgin glass, with a small amount of lubricant added. The ingredients in this product avoid the 800+ chemicals of the Living Building Challenge Red List. The product is designated Red List Free and formaldehyde-free.

What's been done in the design and manufacture in consideration of the potential human health impacts in the use stage

Because Jet Stream Ultra is designed to be blown into walls and attics, it contains a small amount of fossil based lubricant (1 – 2%) to facilitate blowing. The remainder of the product is inert virgin glass fiber. The ingredients of Jet Stream Ultra avoid the 800+ chemicals of the Living Building Challenge Red List. 

This product has a high degree of recycled content, and environmental mining impacts are reduced approximately 60% by using recycled glass rather than virgin materials. The glass formulations used in Knauf products are audited for health & safety using the European Certification Board for Mineral Wool Products (EUCEB) exoneration process.

Where it goes at the end of its life

At this time, the product is landfilled at end of life. We take extended producer responsibility very seriously and have active programs to address end of life. There is no option other than landfills at this time.

How we're making it healthier

Knauf engages very closely with its vendors to eliminate and avoid chemicals of concern. No competitor has as many Red List free products as Knauf Insulation. We continually reduce our environmental impacts through recycled content and optimize our products by designing them to be transformative.
