Rockfon® Plenum Barrier Board installs quickly above interior partitions to provide additional sound blocking benefits. This plenum barrier efficiently expands and contracts with deflection and is easy to install and cut, due to its stone wool core. For optimal performance, combine with CAC 20-40 ceilings.

Performance Properties:

  • Improves sound insulation and privacy between rooms 
  • Installs quickly above interior partitions in ceiling plenums or under interior partitions in raised-floor plenums
  • Lightweight and easy to cut 
  • Conforms around pipes and ducts 
  • Expands and contracts with building deflection

Noise Reduce Coefficient (NRC)

Sound absorption is measured in accordance with ISO 354.

Sound absorption data αp, αw and absorption class are calculated in accordance with ISO 11654. Sound absorption properties of islands and baffles are quantified by the equivalent sound absorption area Aeq expressed as m² per item.
