Siderise CBX Flexible Acoustic Void Barrier for Suspended Ceilings is a lightweight solution specifically engineered to prevent the flanking transmission of sound through the void above suspended ceilings. Designed to enhance the acoustic integrity between adjacent rooms or spaces, the CBX barrier effectively closes off the common air path that sound can exploit over partitioning. It is typically installed vertically within the void, running from the top of a partition wall up to the structural soffit above the suspended ceiling grid. This flexible acoustic barrier is highly adaptable, allowing for straightforward installation around services and irregularities within the void.

Siderise CBX is a thin, flexible quilt that incorporates a central heavy membrane and an 'anti-creep' layer, flanked by foil-faced glass fibre insulation. This unique composition allows it to effectively hang in ceiling voids above partitions, significantly enhancing room-to-room sound separation and minimising flanking noise. Its composition delivers excellent sound reduction performance, helping to achieve desired acoustic ratings and ensure occupant comfort and privacy in commercial, educational, healthcare, and residential buildings. The Siderise CBX is an essential component for robust acoustic design, ensuring that sound doesn't bypass the main partitioning system.
