Application

Siderise CVB/LAM acoustic void barriers are primarily intended to reduce sound transmission via hidden voids offering potential 'cross talk' paths to adjoining areas. For suspended ceilings, typical voids include those formed at partition lines.

CVB/LAM can also be used as a firestop directly above partition lines (in this case the ceiling must be broken either side of the partition). Refer to Fire Performance: Table 2 of manufacturer's technical datasheet for details. Appropriate brackets must be ordered separately.

Description

Siderise CVB/LAM is made of ‘Lamella’ orientation mineral wool (i.e. the internal fibres have a perpendicular

orientation and additionally are held in a pre-compressed state).

The Lamella construction has the advantage of being more compressible in the plane of the barrier, assisting friction and compression fitting and aiding deformation around service penetrations. Siderise CVB is faced as standard on the exposed surfaces with a reinforced aluminium foil and supplied with non-rebated edges.
