  • Super-soft glasswool
  • Made using recycled glass bottles
  • No added formaldehyde
  • Compression packed - more product per pack
  • Helps reduce energy costs

A step up from the Earthwool R-3.0 product, Earthwool R-3.5 Ceiling insulation is still an economical and energy efficient choice with slightly improved energy saving properties, enabling you to keep your home cool in summer and warm in winter. It’s super soft, made using recycled glass, and comes in pre-cut rectangles at either 430mm or 580mm widths to suit most ceiling joist centres. Plus, installation is quick and easy. As well as providing an efficient 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.
