Application

Suitable for free-hanging in ceiling voids above partition lines. Suitable for both new build and refurbishment projects.

Description

SIDERISE CBX acoustic ceiling void barriers are flexible composite quilts designed for free-hanging in ceiling voids above partition lines. The range has been specifically developed to provide a simple solution to the common problem of improving room-to-room sound separation via a common ceiling void. All grades offer exceptional sound reduction properties in comparison to common ad-hoc solutions using standard flexible or resilient materials.


SIDERISE CBX acoustic ceiling void barriers are multi-layered composite materials. The central layer is a thin, flexible, heavy septum membrane. Two types of membrane are available; lead foil or a polymeric heavy salt loaded barrier. Both types incorporate to one side a laminated glass fabric 'anti-creep' layer, to prevent possible long-term elongation of the product in its normal free-hanging condition. This layer also provides additional reinforcement to through penetrations at fixing points. Both types of central membranes provide matching acoustic performance for each of the two standard surface weight options. The primary difference between the types is their mechanical characteristics when bent or deformed. The lead foil membrane tends to memorize deformation. Each side of the membrane has a soft, high-tensile glass fibre insulation layer, faced on the exposed surface with a reinforced aluminium foil.


Features and benefits:

  • Tested systems up to 49 dB Rw.
  • Fully tested acoustic performance.
  • Reduces ‘room to room’ sound transmission.
  • High performance polymeric membranes.
  • Ease of installation.
  • Durable.
