Jump to:
+44 (0)1656 730833 Website

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) 27-44dB
  • Dnf,w up to 55dB
  • 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.
