2 INTERIORS: CEILING VOID BARRIERS SIDERISE insulation solutions for interiors SIDERISE has over 40 years of experience in designing, developing and manufacturing acoustic and fire insulation solutions for building interiors. NOISE CONTROL - A KEY FACTOR Ask people what they most want at work and they will probably say a bit of peace and quiet. We may moan about the noisy neighbours at home but when it comes to the working environment we complain. The most common demands are for improved privacy for discourse and reduced disturbance from intrusive noise. Noise control has become a key factor for consideration by those responsible for building design. The designers challenge is to create an environment that meets an occupant s specified acoustic needs. Proper acoustics, the unobtrusive sum of all sounds, is the key objective for a comfortable environment. DELIVERING EXCEPTIONAL ROOM-TO-ROOM SOUND REDUCTION With over 40 years of expertise we can deliver exceptional room-to-room sound reduction performance for building interiors. We provide interior insulation solutions for: New International Airport, Doha, Qatar Wales Millenium Centre, Cardiff, UK 30 St Mary Axe, London, UK One Canada Square, London, UK Offices Healthcare Education Retail Leisure and Sports Industry SIDERISE products are made from robust sustainable materials, and we are always happy to provide customers with bespoke acoustic and fire solutions to suit their needs.

3 Version 1 : March 2015 SIDERISE ceiling void barrier range The SIDERISE ceiling void barrier range is designed to effectively reduce sound transmission via hidden voids resolving the common issues that cross-talk causes. RESOLVING THE ISSUE OF CROSS-TALK The inclusion of products from the SIDERISE ceiling void barrier range can normally remedy the problem for the conditions described above. Where a common voids sits above the partition it is usual to install the product directly in line with the partition. The Sound Reduction Index or SRI (Rw) of the cavity barrier is not normally required to equal that of the partition itself. This is due to the presence of other obstructions in the room-toroom sound path (e.g. the suspended ceiling). The individual performance of the barrier need only be sufficient to correct the shortfall between the partition and the untreated crosstalk path. Fig 1. Sound Transmission Path CROSS-TALK - A COMMON PROBLEM The sound separation achieved between adjoining rooms or offices is often severely limited by cross-talk via a common void. This occurs when the transmission loss associated with this sound path is less than that provided by the primary separating element, for example, a partition. Voids affected by cross-talk include: Suspended ceiling voids at partitions Access floor voids below partitions Cavities at floor slab edges to façades SUSPENDED CEILING SYSTEMS The actual value of these paths can vary substantially. For ceiling voids, 15-40dB Dnf,w (DnCw) would usually be associated with most suspended ceiling systems., An acoustic engineer can assess a minimum SRI value for the cavity barrier with knowledge of either the existing overall path value or details of the individual path obstructing elements. The SIDERISE technical department can assist in this area. OPEN-CELL AND PERFORATED SUSPENDED CEILINGS Occasionally conditions arise that demand substantially higher SRI values of the cavity barrier, such as ceiling voids formed by open-cell or substantially perforated suspended ceilings. Twin barrier or multiple element arrangements can then be employed to accommodate almost all possible sound performance criteria. Rw values are for the barrier arrangement alone. Room-toroom performance (DnCw) would normally be significantly higher. T: +44 (0) Interiors@siderise.com 3
