FLX Flexible Acoustic Barrier for ceiling

Siderise FLX flexible acoustic barriers for suspended ceilings are flexible composite quilts designed for free- hanging in ceiling voids above partition lines. They have been specifically developed to reduce `room to room’ sound transmission via a common ceiling void.

The product can be cut and formed around localised obstructions within the ceiling void. Being flexible and thin the quilts are ideal for remedial treatment requiring only limited disruption to an existing suspended ceiling during installation.

Siderise FLX are multi-layered composite materials. The central layer is a thin flexible bitumen fee polymeric barrier mat. The membrane barrier incorporates a laminated ‘anti-creep’ layer to prevent possible long-term elongation of the product in its normal free hanging condition. It additionally provides reinforcement to through penetrations at fixing points on each side of the membrane. To each side of the membrane there is an open cell acoustic foam insulation layer.

Siderise FLX is available as standard or with the optional feature of 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.

As Siderise FLX contain no mineral fibre based components so are suitable in applications where mineral fibres must be avoided.

Handling

Siderise FLX are heavy, flexible barriers and care should be taken when handling to protect the product from damage and the handler from personal injury.

Weight per sheet (2000mm x 1200mm std)= 26kg per sheet

Before lifting each sheet should be rolled or folded down the length of the sheet to create a package approximately 1200mm long x 300 - 500mm width/diameter. The product can then be lifted. All standard health and safety lifting/handling techniques should be observed.

In terms of 'Reaction to Fire', the products are classified to EN 13501-1. See Table 1.

The product’s acoustic performance is tested in accordance with BS EN ISO 10140-2:2021. Weighted sound reduction index (dB R_W) values are given below in Table 2.
