Designed to effectively close small apertures and voids encountered in a wide range of building conditions. Used in small and/or irregularly shaped cavities at ‘tops of walls’ which can be found in a wide range of buildings, both new and existing.

The type and thickness of the closure are normally selected in conjunction with the manufacturer's technical department.

Influencing factors include:

• acoustic performance.
• deformation required for fitting.
• size & depth of the aperture.
• dimensional variability.
• shape complexity.
• degree of resilience/recovery required.

Acoustic void closures for tops of walls are supplied as either die-cut or sheets, these semi-rigid composite sheets are designed to close small apertures and voids.

Benefits

• Acoustic performance (Rw) 27-44 dB.
• Dnf,w up to 55 dB.
• Improves ‘room to room’ sound separation.
• Flexible allowing for ease of installation.
• Suitable for new build and refurbishment projects.
