Both Knauf Insulation Earthwool Batts and Bradford Black Batts are made from glass wool which is made from 80% recycled glass material. This glass wool must be bound together to make the insulation product. However, in the case of Earthwool Batts, which are made in Germany, the glass wool is bound together with a plant-based binding agent. This makes them less environment friendly, contrary to popular belief.
