CVB/P10 Acoustic Void Barrier for ceilings and floors
Stone wool acoustic barriers to provide enhanced sound insulation in ceiling and floor voids
Acoustic void barriers for suspended ceilings and floors
The CVB/P10 Acoustic Void Barrier comprises a high-density resin-bonded stonewool insulation with a central mass barrier and reinforced aluminium foil facing. It is designed to reduce sound transmission via hidden voids, such as under access floors and within suspended ceilings.
CVB/P10 Acoustic Void Barrier can reduce room-to-room sound transmission, improving privacy and preventing disturbance from neighbouring rooms
CVB/P10 Acoustic Void Barrier is suitable for use as an acoustic barrier in ceiling and floor voids upto 1200mm
Siderise CVB/P10 acoustic void barriers are primarily intended to reduce sound transmission via hidden voids offering potential ‘cross-talk' paths to adjoining areas. For suspended ceilings or raised access floors, typical voids include those formed at partition lines.
The product can be cut to accommodate service penetrations.
Siderise CVB/P10 is a bonded composite comprising a central 10kg/m² polymeric membrane with high density mineral wool either side. The mineral wool is faced as standard on the exposed surfaces with a reinforced aluminium foil.
As standard is supplied with opposing interlocking rebate joints in one direction. This feature helps maintain acoustic performance at joints between adjacent slabs.
Handling
Siderise CVB/P10 weighs 18kg/m², care should be taken when handling to protect the product from damage and the handler from personal injury.
