2 PRODUCT OVERVIEW PRODUCT OVERVIEW PRODUCT OVERVIEW Resilient Acoustic Stud (RAS) is a simple, new innovation for partitions in hotels and student accommodation projects. RAS is the only product of its type in the world. It comprises two steel profile sections held together by an acoustic tape which prevents airborne and impact sound from passing through separating walls. RAS has two major benefits for specifiers and installers. Whilst meeting the requirements for Part E: Rooms for Residential Purposes and Part E: Change of Use, it provides: A 7mm thinner partition, by consolidating the resilient bar into the unique stud design Up to 50% quicker installation time than the traditional Resilient Bar System method It enables specifiers and installers to meet acoustic requirements quickly and simply, providing a useful alternative to our own Resilient Bar System which we know can be cumbersome to design and install.

3 DESIGN BENEFITS DESIGN BENEFITS HOW RAS WORKS Designed by our acoustic engineers, Resilient Acoustic Stud has a resilient shear-resistant material sandwiched between two metal profiles. The resilient insert is made of visco-elastic material and provides acoustic and thermal break properties. This innovation is our latest solution for the dry construction sector. Solutions that simplify design, improve site productivity and cut wastage. The sound insulation of any partition is governed by three factors: The air gap between the two surfaces of a partition The mass of the two surface boards The amount of connection between the two faces Whilst a traditional metal C stud provides the structural and impact strength for a partition, it actively transmits airborne and impact sounds from one face of a partition to another. Designers need to specify a twin frame partition or a traditional single frame with multiple boards at each side or add additional components such as a resilient bar to overcome this. Whereas RAS reduces the connection between the two sides of the partition within the stud itself.

5 INSTALLATION BENEFITS INSTALLATION BENEFITS INSTALLATION BENEFITS Why Resilient Acoustic Stud is up to 50% quicker than the Resilient Bar System Resilient Acoustic Stud System is a simple alternative to the Resilient Bar System it s just a standard stud and track install, which makes it up to 50% quicker to install because: It is a much simpler design using less material It does not include resilient bars which makes fixing light and plug sockets or other M&E much easier Post installation fixings (e.g. shelving) will not compromise the partition To reduce flexing RAS is made with 0.6mm gauge steel which allows for much easier installation New solution But you don t have to take our word for it... RAS is a great, practical innovation. It has fewer components than the system we d usually use making RAS simpler to install with less product on site. We no longer have to mark the boards to see where the Res Bars are located behind the partition, and it s an easy solution for M&E as sockets etc can be placed anywhere. It makes the installation process much, much quicker.

Stage Cut Siniat Resilient Acoustic Studs to length (5mm shorter than floor to soffit height) using snips or saws no unusual tools or specialist tools are required. Stage Resilient Acoustic Studs may be used as starter studs, at abutments and at junctions. Fix to structure at 600mm centres on both sides of resilient insert. Stage Friction-fit Resilient Acoustic Studs into the floor and soffit tracks, arrange studs to suit board arrangement. Studs may be spliced by boxing only (see Fig. ). Stage 5 Fit boards with Siniat Performance Drywall Screws at 600mm centres to inner layer and 00mm centres to outer layer. Do not use screws longer than 5mm for the inner layer and 5mm for the outer layer. Vertical board joints to be staggered between layers and opposing sides. Stage 7 Horizontal boards joints should be reinforced with GTEC FS50/Rx Flat Strap between board layers. Stage Door jambs to be formed in accordance with standard Siniat details using standard GTEC C Studs and U-Tracks. Stage 9 Seal perimeter of partition with GTEC Intumescent Acoustic Sealant. Stage 0 Finish partition with skim plaster (Universal and db board only) or tape and joint (all boards). Use Megadeco board and Deco Joint Filler and Deco Joint Cement to eliminate need for sealing prior to decoration.

Warranties Hands Eyes Gloves should be worn when handling metal sections and components to avoid risk of lacerations. When cutting strapping or metal sections, wear eye safety protection compliant with BS EN 66:00 A5. Sections are supplied in bundles with small packs strapped together to form larger packs suitable for forklift truck offloading. Packs should be stacked in a safe and stable manner. Pack strapping should not be used for lifting. Coils and metal sections may spring apart when strapping is released. Siniat products and components are rigorously tested together. By completing this testing we are able to guarantee the technical of our systems throughout the project lifecycle. When systems are built with the correct components and materials, installed by qualified professionals in accordance with our latest literature and relevant standards, Siniat offers our invaluable Lifetime System Warranty. In the unlikely event of failure, provided the system is unaltered, as originally designed and built, Siniat will reinstate the system to it s originally specified level giving you and your client peace of mind. When handling sections, wear overalls and suitable clothing. Respiratory If fume or dust is produced, ventilate the area of storage or work. When welding, flame cutting or grinding, wear approved respiratory equipment. Eye protection should be worn when using hand tools. Exposure to weather should not exceed months.
