Acoustic Insulation

There are two main reasons for Acoustic insulation and they are to reduce and control the transmission of noise through structures such as walls and floors and secondly to dampen sound reverberation within a room.

Noise has the affect of raising stress levels, disrupting sleep and generally reducing your quality of life. Common noise disruptions such as traffic noise, flight paths and powerful entertainment systems have an impact on noise levels in your home. Acoustic insulation can assist in areas which are more prone to noise transference, including;

  • Bathrooms
  • Ensuites
  • Laundries
  • Home Theatres
  • Kid’s Rooms, Nurseries
  • Study
  • External Noise


Pink® Soundbreak™ is specially designed to provide exceptional acoustic performance in residential building applications. The high-density composition of Pink® Soundbreak™ makes it the ideal solution for reducing sound transfer through walls(both internal and external), ceilings and between floors, thus allowing for quieter home environments.

With a nominal density range of 24 – 26kg/m3, Pink® Soundbreak™ acoustic insulation provides the added benefit of remarkable thermal performance; this improves the energy efficiency of a home which in turn provides energy cost savings. The high density composition of Pink® Soundbreak™ makes it the ideal solution for achieving higher R-values within limited cavity spaces.

Pink® Soundbreak™ acoustic insulation is renowned for its firmness, making it easy to install between standard stud spacings – both timber and steel - ensuring it remains in place for ongoing acoustic and thermal performance. Moreover, thanks to advances in formulation, Pink® Soundbreak™ is low itch - making it comfortable to handle during installation.

EarthWool® Sound Control Batts provide a cost-effective thermal and acoustical barrier for energy-efficient construction. The batts’ consistent quality, low dust and clean-cutting resilient fibres make fabrication easy and installation fast.

Using the EarthWool® high performance wall insulation together with other design features in your home significantly reduces the amount of noise to acceptable levels.

EarthWool® is rot-proof, odourless, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria. It is chemically neutral, does not contain impurities and comes with a 50 year warranty.

ECOSE® Technology

Earthwool products made using ECOSE® Technology benefit from a binder which has no added formaldehyde and is based on renewable bio-based materials instead of traditional petroleum-based chemicals. The technology has been developed for Knauf Insulation’s glasswool and rock mineral wool products, enhancing our environmental credentials whilst maintaining the thermal, acoustic and fire performance and mechanical properties.

ECOSE Technology gives a distinctive new look to Knauf Insulation’s Earthwool products - a natural shade of earthy brown, with no added dyes, bleaches or artificial colours. Earthwool is also less dusty and has a much softer and friendlier feel whilst retaining its rigidity and stiffness properties. The ECOSE Technology binder is up to 70% less energy intensive than the formaldehyde binders used in traditional glasswool insulation. As there is no formaldehyde or phenol used in the manufacturing process for Earthwool, it also improves the indoor air quality of buildings where these products are installed (compared to conventional glasswool products).

Knauf Insulation’s Earthwool® products provide Australia with a new choice of highly sustainable insulation.

New Generation Soundscreen Batts (Previously referred to as ' Rockwool Soundscreen insulation batts ') provide high levels of thermal and acoustic insulation and reducing noise transfer levels significantly.

Bradford SoundScreenTM is a high density insulation product specifically made for wall, floor and ceiling applications where superior acoustic performance is required. It is manufactured from a specially formulated mineral wool and bonded with a thermosetting resin. The wall batt range (which can also be used on suspended floors) is formulated with water repellent to limit moisture ingress into buildings.
