We believe insulation should be kinder to those who use it the most.

ECOSE® Technology is our unique bio-based binder which is used in the manufacture of all of our Glass Mineral Wool products.

Our Mineral Wool made with ECOSE® Technology contains no added formaldehyde or phenol. This means our insulation generates very low levels of dust, increasing the comfort of those handling it. ECOSE® Technology makes our insulation soft to touch and easy to handle.

It is made from natural raw materials that are rapidly renewable and is 70% less energy intensive to manufacture than traditional binders, so it is kinder to the environment too.


Products manufactured using ECOSE® Technology have a natural brown colour so you can see, as well as feel the difference.

Frequently Asked Questions ABOUT ECOSE® TECHNOLOGY

Did Knauf invent this technology?

Yes. The technology was developed by Knauf in order to improve environmental compatibility without compromising thermal, acoustical or fire protection performance characteristics.

What does the name ECOSE® stand for?

The name embodies the ecological and sustainable components of the binding agent technology. The abbreviation (ECOlogical, Sustainable, Environmental) highlights the ecological, sustainable and environmentally-friendly importance of this scientific breakthrough.

Why do products with ECOSE® Technology look different?

The colour change is due to the natural reaction of the binding agent during curing. No dyes or pigments are added to the products.

Is there a medical categorisation regarding the safety of this product?

We subject all of our products to extensive health and safety tests. A material and safety data sheet has been produced for glasswool with ECOSE® Technology and of course all of the fundamental quality certificates such as EUCEB remain valid.


Knauf insulation 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. ECOSE® Technology gives a distinctive new look to Knauf insulation glasswool products - a natural shade of earthy brown, with no added dyes or artificial colours. Knauf insulation glasswool is also less dusty and has a much softer and friendlier feel whilst retaining its rigidity and stiffness properties.
