Bradford Acoustigard Partition Rolls are manufactured by spinning molten glass into fine wool-like fibres, containing up to 65% recycled glass content. These inorganic, non-combustible fibres are bonded together using a thermosetting resin and the product can be identified by its golden appearance and is supplied un-faced.

Features and Benefits


  • Excellent acoustic properties - helps reduce sound transmission through wall systems
  • Non combustible fibre - does not add to the fuel load in the building
  • Friction fit to suit commercial stud spacing – no stapling required
  • All products thermally rated to AS4859.1 to control performance characteristics 
  • Compression packaged - easily handled and stored on-site improving m2 per movement on site.
  • Made from a safe to handle Fibre Bio-Soluble (FBS-1) formulation
  • Made in Australia for Australian conditions
