SIDERISE CVB | Acoustic Void Barriers

Siderise acoustic void barriers are primarily intended to reduce sound transmission via hidden voids offering potential ‘cross-talk’ paths to adjoining areas. Typical examples include, suspended ceiling or raised access floor voids at partition lines, and the cavity formed at floor slab abutments to curtain walls.

• Frequently the sound separation achieved between adjoining rooms or offices is severely limited by ‘cross-talk' via a common void. This occurs when the transmission loss associated with this sound path is less than that provided by the primary separating element (e.g. partition or floor).
• The inclusion of Siderise acoustic void barriers can normally remedy this problem for all of these conditions.
• Note: This product was previously known as Lamaphon CVB series acoustic void barriers.
• Sound Reduction: Tested systems up to 49dB (Rw)
• Fire resistance: up to 1 hour

  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. The surface weight of the polymeric membrane (P10) is 10 kg/m².
  
  Features and benefits:
  Sound Reduction: Tested systems up to 49 dB (Rw) (twin barrier system).
  Fire resistance: up to one hour.
  Improved room isolation and reduced 'cross-talk'.
  Simple to fix and easy to cut to accommodate service penetrations.
