Acoustic Insulation

Earthwool Acoustic Insulation offers the latest in insulation technology. The next generation of glasswool insulation, it is not only safer and more environmentally friendly than any of its predecessors, it is also easier to handle and install.

The Earthwool Acoustic Insulation Difference

Earthwool acoustic offers a range of benefits that no other acoustic insulation can match. It has been developed using advanced technology, and with the end user in mind. A firm focus has been put on quality, performance and ease of installation.

So how does Earthwool Acoustic differ from other acoustic installation options? Let’s take a look.

Advanced Compression Packaging

Earthwool Acoustic insulation can be easily transported and stored. It is easy to move and handle and takes up minimal room, perfect for projects where space is at a premium. Earthwool Acoustic rolls are packaged in strong poly bags which offer excellent protection to the insulation while in storage, guarding against dust, moisture and abuse. With the help of MasterBag batt units which contain multiple packs, you’ll get more square metres per bag and more square metres per truck load, resulting in fewer trips to Bunnings and less space needing to be set aside for storage.

Ease of Installation

Earthwool Acoustic Insulation is second to none when it comes to ease of installation. The glasswool construction is of a consistent quality, allowing for an incredibly clean cut. This also means that minimal dust is created when the rolls are sliced up. Earthwool Acoustic Insulation is a highly resilient insulation that quickly recovers from its compression packed state to full thickness, allowing for quick installation, a snug in-situ fit and excellent finished aesthetics. Detailed instructions come with each roll, ensuring that even the most inexperienced of installers will be able to work productively. Your installation teams will never be more efficient than with Earthwool Acoustic.


Earthwool Acoustic also offers superior performance, being used to upgrade both the acoustic and the thermal performance of masonry walls in structures both residential and commercial. Our Acoustic Roll can improve the Rw rating (the weighted sound reduction index) of a wood stud construction by 3-5 decibels, and a metal stud construction by 8-10 decibels, while our Acoustic Internal Wall Batts come in a range of different densities – Basic Performance (11kg/m³) and Ultra Performance (14kg/m³) through to High Density (17kg/m³, 20kg/m³ and 27kg/m³). Earthwool Acoustic can be used on both the exterior and interior walls of a structure.

Resilience and Durability

The resilience and durability of Earthwool Acoustic insulation also sets it apart from the rest. Earthwool Acoustic is completely odourless, non-hygroscopic and rot proof. It is also designed to actively discourage vermin from sustaining themselves within it, and will not encourage the growth of fungi, mould or bacteria. Earthwool Acoustic is the preferred insulation choice by professional installers interested in quality, appearance and efficiency.

What’s more, the name doesn’t lie – Earthwool Acoustic is the best choice for the earth. Made from recycled glass and with no added formaldehyde, it’s one of the greenest insulation choices on the market. And the performance is such that our customers will be using far less energy to heat and cool their homes.
