Knauf Insulation, Inc. (Knauf), the North American division of Knauf Group, a leading, family-owned global manufacturer of fiberglass insulation, announced today that it will become the first fiberglass insulation manufacturer to be entirely formaldehyde-free across its product portfolio by the end of this year.



The final stages of the transition will begin on January 1, 2026, during which all remaining manufacturing equipment that uses formaldehyde to manufacture fiberglass insulation will be removed from the plants. This milestone reflects Knauf’s long-term commitment to high-performing, sustainable insulation products through its ECOSE® Technology, a plant-based binder that replaces traditional formaldehyde-based ingredients.


“Achieving completely formaldehyde-free product lines is a momentous achievement for Knauf and our industry,” said Matt Parrish, CEO of Knauf Insulation North America. “We’ve been on this journey for more than a decade, continually innovating to make the highest quality products for the people who make them, the contractors who install them, and the homeowners and building occupants who live with them every day.”


Knauf introduced the bio-based binder, ECOSE Technology, to the market in 2009, providing a smarter alternative to the phenol formaldehyde binders traditionally used in fiberglass insulation products, and setting a new industry standard for sustainable insulation. That innovation is the foundation for the company’s entire fiberglass portfolio, delivering performance and comfort without added formaldehyde or dyes.


In addition to a product portfolio that is formaldehyde free, Knauf is the only insulation manufacturer with a full portfolio of commercial, industrial and residential products that are Asthma & Allergy Friendly® Certified and Verified Healthier Air™.



“Our focus has always been on continuous improvement and setting a higher standard,” Parrish added. “Reaching this point reflects the dedication of our teams, our investment in innovation, and our commitment to healthier, high-performing spaces.”
