Application

The Siderise AB10 is a flexible acoustic membrane for use as a mass barrier above the Siderise CW-FS fire stops in curtain walls. Using this acoustic upgrade can offer a significant improvement to the acoustic performance of the firestop. Incorporating mass barriers such as the Siderise AB10 into slab-edge details is often crucial for controlling floor-to-floor sound transmission.

Siderise AB10 is quick and easy to install and is suitable for use in all curtain walls. The product is thin, flexible, and designed to accommodate façade movement, unlike traditional mass-barrier materials such as steel or plasterboard.

Description

Siderise AB10 Acoustic Barrier Overlay comprises a high-mass limp elastomeric membrane applied to a dense acoustic foam layer. The upper surface is faced with reinforced aluminium foil. The entire product is 12 mm thick.


Acoustic considerations:

The fire stop between the floor slab and façade represents a point of significant potential weakness in vertical sound transmission between floors.


Acoustic performance:

As the AB10 Acoustic Barrier is sold as an acoustic upgrade for our CWFS firestops, we have not tested its standalone performance, however for the purposes of assessment by project acoustic consultants, the Weighted Sound Reduction index (dB Rw) of the mass barrier layer alone is 32 dB(Rw).

Additional acoustic performance increases can be achieved by combining the AB10 and CWFS with the Siderise CVB/C-10 cavity barrier. Contact our technical team at technical.services@siderise.com for performance guidance or 1/3rd octave test data.


Acoustic improvement to the firestop zone:

The Siderise AB10 has been developed for use with our Siderise CW range of perimeter barriers and fire stops for curtain walling.

Siderise fire stops already offer a good level of sound insulation performance (typically 22-25 dB Rw). This can be increased to 37 dB Rw by the addition of a Siderise AB10 overlay.

If further performance increases are required, our CVB/C-10 cavity barrier can be used in addition to achieve up to 51 dB Rw.


Features and benefits:

  • Reduces floor-to-floor sound transmission.
  • Ideal for remedial treatment after installation of firestops.
  • Accommodates façade movement.
  • Deforms to contours.
  • Quality assured to BS EN 9001.
