Compared to rock wool and fibreglass, earthwool has a much softer texture that is similar to cotton. The density of earth wool is usually very low, at 20kg/m3. Rockwool and fibreglass must be handled with proper protection because the microfibres can penetrate the skin. Earthwool is designed to be easier to handle with its itch-free properties. It is made of 80% recycled glass and sustainable bio-based binder. It also shares the same non-combustible properties and thermal performance as rockwool and fibreglass.
There is also a rigid version of earthwool that provides a firmer touch for use in acoustic panels. But the firm earthwool is a relatively new product, and require more testing to be done before they are commonly available for purchase.
