Earthwool® glasswool products made using ECOSE® Technology benefit from a binder which has no added formaldehyde and is based on renewable bio-based materials instead of traditional petrol-based chemicals. The technology has been developed for Knauf Insulation’s glasswool and rock mineral wool products, enhancing our environmental credentials whilst maintaining the thermal, acoustic and fire performance and mechanical properties.

ECOSE® Technology gives a distinctive new look to Knauf Insulation’s Earthwool® glasswool products - a natural shade of earthy brown, with no added dyes, bleaches or artificial colours. Earthwool® glasswool is also less dusty and has a much softer and friendlier feel whilst retaining its rigidity and stiffness properties. The ECOSE® Technology binder is less energy intensive than the formaldehyde binders used in traditional glasswool insulation. As there is no formaldehyde or phenols used in the manufacturing process for Earthwool® glasswool, it also improves the indoor air quality of buildings where these products are installed (compared to conventional glasswool products).

The new generation of glasswool made using ECOSE® Technology is already used in buildings throughout the USA, UK, Europe and Australasia.
