SIDERISE FLX a flexible composite acoustic quilt used for free-hanging in ceiling voids above partition lines to significantly reduce sound transmission between rooms acoustic performance 23-27dB Rw.
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. The barrier’s flexibility allows it to be easily deformed around localized obstructions within the ceiling void.
SIDERISE 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 polymeric heavy salt loaded barrier. On each side of the membrane is a Class ‘O’ 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 memorize deformation. It is extremely quick and easy to install and is suitable for both new build and refurbishment projects.
