Siderise FLX – Flexible Acoustic Barriers for Suspended Ceilings – Technical Data

Version: 1.00 - Release Date: December 2018

Application

SIDERISE FLX flexible acoustic barriers for suspended ceilings are flexible composite sheets designed for free hanging in ceiling voids above partition lines.

They provide a simple solution to the common problem of improving `room to room’ sound separation via a common ceiling void.

All grades offer excellent sound reduction properties in comparison to commonly employed ‘ad-hoc’ solutions based on standard flexible/resilient materials.

The barrier is extremely quick and easy to install and its flexibility allows it to be easily deformed around localised obstructions within the ceiling void.

The product is suitable for both new build and refurbishment projects.

Product Description

SIDERISE FLX flexible acoustic barriers for suspended ceilings 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 heavy salt loaded polymeric barrier. On each side of the membrane there is a Class ‘0’ open cell acoustic foam insulation layer.

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 has a tendency to memorise deformation. In consequence the final selection of membrane is normally at the contractor’s preference.

SIDERISE FLX is available as standard with two optional features:

Reinforced aluminium foil finish to one side. This facing simplifies the sealing of service penetrations as it permits the application of self-adhesive foil tapes. The finish also acts as an integral anti-creep layer.
Internal glass fabric anti-creep layer. This minimises the risk of possible long-term elongation in high void conditions. This option is not required if the aluminium foil finish described above is selected.
