Earthwool Internal Wall (Acoustic) Batts

Acoustic Insulation BattsEarthwool® Internal wall batts are a new generation of super-soft, sustainable glasswool for the acoustic insulation of internal walls. This specialist acoustic range of insulation products is available in Basic Performance (11kg/m³), Ultra Performance (14kg/m³), High Density (17kg/m³, 20kg/m³ and 27kg/m³) sound absorbing performance levels.

Earthwool Internal wall batts reduce transmission from room to room or office to office. A comprehensive range of tested and warranted acoustic wall systems using Earthwool can be found at www.knaufplasterboard.com.au.

Advanced compression packaging reduces handling time and the storage space required on site.

Earthwool Internal wall batts are available at your local Bunnings Warehouse.

If you're installing Earthwool yourself then don't forget to check out our DIY Safety Instructions and Precautions before you start.

Acoustic Insulation BattsApplication
Earthwool Internal wall batts provide a cost-effective acoustic barrier to reduce sound transmission through internal walls. The consistent quality, low dust, and clean-cutting resilient glasswool makes fabrication easy and installation fast. Earthwool Internal wall batts can be used in timber and metal frame applications in residential and commercial structures. These applications include acoustic treatments to walls.

Knauf Insulation offers Earthwool Internal wall batts in a wide range of R-Values and densities to provide high acoustic performance and comfort – absorbing unwanted noise and also providing a thermal barrier between different temperature rooms. They are highly resilient, recovering quickly to full thickness.

Proven Performance

  • Preferred by professional installers concerned with quality, appearance and productivity. 
  • Excellent acoustical properties reduce sound transmission in the home when properly installed in walls, ceiling and floor systems. 

Durability

  • Earthwool Internal Wall Insulation Batts are odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria. 

Superior Handling

  • Highly resilient insulation recovers quickly to full thickness for a snug fit and superior finished aesthetics. 
  • Consistent quality materials feel good, cut easily and install fast. 
  • Low dust for easier handling and increased productivity. 

Convenient Packaging, Easier Handling

  • Earthwool Internal Wall Insulation Batts are packaged in a strong, white poly bag that offers excellent protection from abuse, dust and moisture. 
  • Earthwool Internal Wall Insulation Batts packages feature easy to follow installation instructions. 
  • MasterBag batt units (containing multiple packs) ensure reduced handling costs with improved compression – more square metres per bag, more square metres per truck load, fewer trips to the job site and less warehouse space for storage. 

Superior Service and Support

  • Knauf Insulation is totally focused on providing first class customer service, producing high quality product and ‘on time in full’ deliveries. 
  • Knauf Insulation recognises the need to establish, develop and support a professional network of distributors and re-sellers in order to service a growing insulation market. 
  • Knauf Insulation is committed to providing a comprehensive range of relevant literature and web-based technical information to support specifiers and consumers.
