Type 1
Acoustic void closures for tops of walls.
Application
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.
Description
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.

Material | Foam.Guidance for specification option: Closures are produced from a resilient foam material only. Commonly made from Lamacell closed cell foam. Type 1 closures are ideal for very small apertures or situations requiring a less demanding sound insulation performance. May also be produced from SIDERISE ‘V’ foam as a supporting backing infill for subsequent site application of an acoustic sealant/ mastic to the surface. |
