Application

For use in suspended ceiling and raised access floor voids to reduce sound transmission between rooms.

Description

SIDERISE CVB – Acoustic Void Barriers for Ceilings and Floors reduce sound transmission via hidden voids offering potential 'cross-talk' paths to adjoining areas. SIDERISE CVB is designed for free-standing in both ceiling and raised access floor voids.


As standard, the product incorporates opposing interlocking rebate joints in one direction, helping to maintain acoustic integrity at joints within the installed barrier. 


SIDERISE acoustic void barriers are available in several grades and thicknesses offering a wide range of sound reduction values. The product is also available with a choice of optional high mass central membranes to achieve substantially higher SRI values. 


Some SIDERISE CVB barriers have certified fire resistance, permitting their dual use as ceiling or floor void fire barriers. 


The rockfibre insulation core is available in two different structural forms:

  • SFO (conventional, i.e. direction of the internal fibres predominantly aligns with that of the barrier itself).
  • HSL (special ‘lamella’ construction, i.e. the internal fibres have a perpendicular orientation and additionally are held in a pre-compressed state).

The SFO form is also optionally available with the inclusion of a central limp heavy membrane. Two surface weights of the polymeric membrane are available: P5 (5 kg/m²) or P10 (10 kg/m²).


Features and benefits:

  • Sound Reduction: Tested systems up to 49 dB (Rw).
  • Fire resistance: up to one hour.
  • Improved room isolation and reduced 'cross-talk'.
  • Simple to fix and easy to cut to accommodate service penetrations.
