Benefits of Acoustic TripleDeck / MultiPanel

  • Non-load bearing partitions can be built off the finished floor surface
  • Laid straight onto the joists, no sub-deck required
  • Easy installation process, uses only one primary component to provide insulation and a finished floor surface
  • Offers high performance to height ratio

Typical Applications

  • Refurbishment projects where the floor boards are to be lifted
  • Ideal for use when improving an existing structure where access is only available from one side
  • When height restrictions exist but reliable performance is still required
