What are the primary ingredients in these products?

  • AtmosphereTM duct board, duct liner, and duct wrap contain three primary ingredients:
    Sand, one of the world’s most abundant and renewable resources
  • Post-consumer glass (Knauf Insulation has achieved a UL Environment claim validation for a minimum of 50% post-consumer recycled glass content in our insulation products)
  • ECOSE® Technology binder


What is ECOSE® Technology?
ECOSE® Technology is a binder chemistry that makes Knauf Insulation products more sustainable. It features rapidly renewable bio-based materials rather than non-renewable petroleum-based chemicals traditionally used in glass mineral wool insulation products. ECOSE® Technology reduces binder embodied energy and does not contain phenol, acrylics or artificial colors. For more information, visit


How are these products “carbon negative”?
This means the Knauf Insulation products used for thermal insulating purposes recover the energy that it took to make them in just hours or a few days, depending on the application. Once installed, the product continues to save energy and reduce carbon generation as long as it is in place.


What does it mean to have GREENGUARD Certification?
Products are certified to GREENGUARD standards for low chemical emissions into indoor air during product usage. Knauf Insulation achieved GREENGUARD GOLD Certification and is verified to be formaldehyde free. For more information about GREENGUARD standards, visit:


Will these products help my project achieve LEED® Certification?
Use of this product may help building projects meet green building standards as set by the Leadership in Energy and Environmental Design (LEED) Green Building Rating System.

  • MR Credit 4.1 – 4.2 Recycled Content
  • MR Credit 5.1 – 5.2 Regional Materials


Why is the number “3” in the Atmosphere logo?
This is a nod to our modern atmosphere, which is referred to as Earth’s “third atmosphere.” This atmosphere came about because of oxygen-producing living organisms. It is composed of nitrogen gas (about 78%), oxygen (about 21%), water vapor (up to 4%), carbon dioxide (about 0.360%), and lots of lesser compounds.
