  • Two way Fire Resistance Rating
  • Inter-tenancy
  • Corridors
  • Interior walls
Scope of Use

Whisperwall:

  • Developed to provide superior acoustic properties with additional fire rated properies
  • Interior wall construction

Double Steel:

  • Generally used where two way FRR (Fire Resistance Rating), or superior acoustic performance is required
  • Mainly inter-tenancy walls and corridors

Staggered Stud:

  • Commonly used to provide effective resistance to sound transmission and acoustic impact
  • Two way FRR
Limitations on Use

Double Steel and Staggered Stud:

  • Recommended maximum wall height is 2700mm

Whisperwall:

  • To achieve tested STC values install Pink Batts glass wool acoustic installation R1.8
  • No SRP Continuous Nog Tracks or spliced SRP Studs to be used, doing so will compromise STC values
