Siniat Resilient Acoustic Stud


Aimed at helping achieve acoustic performances on site. Allows for easy cutting and maintains its shape during installation (removing the chance of ‘screw popping’).


Available in two sizes, the Resilient Acoustic Stud (RAS) range is a game-changing innovation for party wall and external corridor wall partitions. It is a simple C-stud which has an inbuilt acoustic material preventing airborne and impact sound from passing through dividing walls.

RAS 90 can deliver the acoustic requirements of Approved Document E, whilst reducing the partition width by 50 mm, releasing significant development value for clients.

Features and benefits:

  • Delivers a thinner partition footprint to help generate greater sales revenue.
  • Simpler design to meet part E acoustic requirements.
  • Fully tested and warranted system - it comes with the usual Siniat Lifetime Warranty as standard.
  • The metal frame installation is up to 50% quicker to install than a traditional twin frame system.
  • There is less material to handle on site.
  • There are no resilient bars within the partition for follow-on trades to breach, reducing the risk of acoustic failure.
