Earthwool R-2.5 Wall insulation offers high performance, with exceptional acoustic and energy saving properties, creating a peaceful environment in your home by absorbing sound and keeping it where it should be. It’s super soft, made using recycled glass, and available in thicknesses to suit 75mm and 90mm timber frames. Plus, installation is quick and easy. As well as providing a high result, this product is extremely durable and comes with a 50-year warranty, so will stand the test of time.

Earthwool is naturally brown – containing no added phenol, formaldehyde, acrylics or artificial colours. It is in full compliance with formaldehyde-free specifications. Earthwool doesn‘t look or feel like any glasswool insulation you‘ve ever experienced. That‘s because the natural brown colour represents a level of sustainability and handling never before achieved. We didn‘t choose brown, it just came naturally.
