Steelwork Isolation System – Farrat CineSTEEL MAX

  • Commercial cinemas.
  • Multiplex cinemas.
  • 4DX cinemas.


Steelwork acoustic isolation system, designed for use with stadia seating frames, supporting 4DX cinema technologies.

Features and benefits:

  • Developed following research into cinema motion technology.
  • High performance.
  • Designed specifically for 4DX auditoria.
  • Incorporates high damping isolators to control and constrain vibration while still providing high levels of sound insulation.
  • The system is based on hot-rolled structural steel supporting 150 mm thick cast in-situ concrete stadia.
  • Future-proofed using the most extreme calibration routines from 4DX suppliers, CineSTEEL MAX not only isolates the vibration from adjacent auditoria, but also controls the inertial response in the structure that the 4DX seats are mounted to, offering superior motion feedback and a more immersive 4D experience.
  • Warranty: Up to 25-years.
