  • the present invention provides an acoustic insulated ceiling system.
  • the system comprises a first profile and a second profile.
  • the system comprises a carrier layer connected to the first profile and the second profile. As such the carrier layer is suspended between the first profile and the second profile.

  • the top layer is a plate, i.e. a top plate.
  • the top layer is arranged above the intermediate layer.
  • the top layer supports on the intermediate layer. The top layer extends from the first profile to the second profile.
