Earthwool Internal Wall (Acoustic) Insulation Batts provide a cost-effective acoustic barrier to reduce sound transmission through a building. The consistent quality, low dust, and clean-cutting resilient fibres make fabrication easy and installation fast.

These applications include acoustic treatments to walls, ceilings and floors. Knauf Insulation offers Earthwool in a wide range of sizes, densities 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 greatly reduces the transmission of noise in the home and also provides a thermal barrier between different temperature rooms.
