CDM-PSJ & CDM-PRJ

CDM-PSJ, elastomer isolation joist hangers, and CDM-PRJ, spring isolation joist hangers, are designed to support suspended ceiling systems off joist structural floors, optimising sound insulation between vertically stacked rooms.

System features:

  • Cost effective
  • Quick and easy to install
  • Standard elastomer hangers are:
    CDM-PSJ-150: 10-20 kg per hanger
    CDM-PSJ-350: 20-45 kg per hanger
  • Standard hangers spring hangers are:
    CDM-PRJ-80: 5-10 kg per hanger
    CDM-PRJ-250: 10-35 kg per hanger
    CDM-PRJ-500: 25-60 kg per hanger
  • Natural frequency at design load between 8 and 10Hz for elastomer hangers and 4Hz for spring hangers
  • Can be used to hang down most suspended ceiling systems
  • Steel elements are Zinc plated, springs are powder coated
  • Bespoke hangers can be manufactured to meet specific loading and natural frequency requirements on request
  • System comes with perimeter isolation strip to isolate the perimeter of the ceiling from the surrounding structures

To specify which CDM-PSJ or CDM-PRJ hangers you require CDM’s engineers will need the following information:

  • The weight and construction of the supported ceiling – this will determine the type of hanger
  • The weight of any elements supported off the suspended ceiling or directly off a hanger
  • The required void between the supporting soffit and the suspended ceiling
