Knauf Insulation's fiberglass manufacture will be formaldehyde-free next month.

Knauf Insulation will become the first fiberglass insulation manufacturer to be entirely formaldehyde-free across its product portfolio by the end of the 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 commitment to sustainable insulation products through its Ecose Technology, a plant-based binder that replaces traditional formaldehyde-based ingredients.

Knauf Insulation is the North American division of Knauf Group.

Matt Parrish, CEO of Knauf Insulation North America, said: “Achieving completely formaldehyde-free product lines is a momentous achievement for Knauf and our industry.

“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 aa alternative to the phenol formaldehyde binders traditionally used in fiberglass insulation products.

That innovation is the foundation for the company’s entire fiberglass portfolio, delivering performance and comfort without added formaldehyde or dyes.
