Features and Benefits

Product Dimensions

Each sheet is 24″ x 48″ x 2″.

Noise Reduction

Excellent sound absorption characteristics, an important benefit for today’s office and interiors.

Indoor Air Quality

Certified for indoor air quality as a low emitting product by UL Environment GREENGUARD and the more stringent GREENGUARD Gold standard; also verified to be formaldehyde-free.


Carbon-negative: Knauf Insulation’s 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.

ECOSE Technology is a revolutionary binder chemistry that enhances the sustainability of our products. The “binder” is the bond that holds our glass mineral wool product together and gives the product its shape and brown color. ECOSE Technology is a plant-based, sustainable chemistry that replaces the phenol/formaldehyde (PF) binder traditionally used in glass mineral wool products. Products using ECOSE technology are formaldehyde-free and have reduced global warming potential when compared to our products of the past.

Glasswool insulation with ECOSE® Technology contains three primary ingredients:

  • Approximately 50% recycled post-consumer glass content verified every 6 months by UL Environment.
  • Sand, one of the world’s most abundant and renewable resources
  • Knauf’s green chemistry initiative ECOSE® Technology, which reduces binder embodied energy by up to 70%

This product contains no materials or chemicals on the International Living Building Institute’s Red List.
