Earthwool DIY Multi-Use Insulation Rolls provide a cost-effective thermal and acoustic barrier for energy-efficient construction. The consistent quality, low dust, and clean-cutting resilient glasswool make fabrication easy and installation fast. Earthwool insulation can be used in timber and metal frame applications in residential structures.

These applications include thermal and acoustic treatments to walls, ceilings and floors. Knauf Insulation offers Earthwool in a wide range of sizes and R-values. Earthwool insulation can be used for cavity walls, floors, ceilings, attics, basements and crawlspaces. It is highly resilient, recovering quickly to full thickness. It also greatly reduces the transmission of noise in the home.
