Sound and strong acoustic stud

A simple new innovation for partitions in hotels, student halls and change of use projects, Siniat’s Resilient Acoustic Stud is the only product of its type in the world

In association with

The sound insulation of any partition is governed by three factors:

  • The air gap between the two surfaces of a partition
  • The mass of the two surface boards
  • The amount of connection between the two faces

A traditional metal C-stud gives a partition structural and impact strength, but it actively transmits airborne and impact sounds from one face of a partition to another. To overcome this, designers need to specify a twin frame partition or a traditional single frame with multiple boards at each side or add additional components such as a resilient bar.

In contrast, Siniat’s new Resilient Acoustic Stud (RAS) has a resilient shear-resistant material sandwiched between two metal profiles, which provides acoustic and thermal break properties, preventing airborne and impact sound from passing through separating walls.

It achieves 58 Rw (-6Ctr) in laboratory testing, providing at least 43 DnTw + Ctr on site. This meets the performance requirements for Part E: Rooms for Residential Purposes and Part E: Change of Use and has the following benefits:

  • A 17mm thinner partition
  • A simpler design using less material
  • Up to 50% quicker installation time than the traditional Resilient Bar System method
  • Student accommodation with Siniat's Resilient Acoustic Stud
