Wall Panelling-Fabric Finish Supply and installation of Anutone Stretch NRC wall fabric system by using FR Grade NRC fabric of size 1700mm width, shall be stretched by using wooden base 10mm thick, rigid vinyl Stretch Tracks half wrap/full wrap 15mm (FS15) and Midseam 15mm (FS15), strand board, synth PF infill with requisite accessories & tools. Wooden base 10mm is first installed on the strand board along the marking lines with metal fasteners inserted at 300mm centers . FS15 tracks to be installed on wooden base, after applying adhesive on both surfaces for a true and continuous secure grip, and heavy-duty fasteners at 150mm centers on one/both sides of Stretch Tracks. Strand square edge magnesite bonded pinewood fiber panels of size 600x1200x20mm having density 400kg/m3, weight 4kg which is fixed to wall with suitable fasteners. Synth PF 10x25mm thick adhered on strand panel by using adhesive. Fabric of width 1700mm is then aligned to the Stretch tracks by following the fabric thread line or pattern. The fabric is stretched and tucked into the Stretch tracks and secure into the locking jaws so that it will be smooth, free of wrinkles with the tucking tools. Note -minimum 50mm additional fabric is required for tucking hence maximum module wall fabric width would be 1600mm.The fabric should be 99% acoustically transparent .The whole system should give NRC of 0.75 Technical Parameters • Core - pinewoodfibre & polyfibre • Fire – 1 • Acoustics – NRC 0.85 • Climate (OC RH) – 49, 90 • Termite resistance – Yes • Light reflectance – Colour dependent • Green (RC %) – 25 • Hygiene (VoC, Clean room) – Low, Class 1

False Ceiling Supply and Installation of Anutone Subtex Nubby,square edge, Glassfibre core fully encapsulated ceiling tile of size 595x595x15mm having volume density 120Kgs/m3, weight 1.8kg/m2 which is suspended by using 0.3mm thick Anutone Skelet TrelisT15 metal grid system.Anutone Skelet TrelisT15 metal grid system of 600x600mm module includes Anutone Skelet WA15W30 wall angle with unequal flanges of 15/19mm, length 3000mm, fixed along the perimeter of walls with the help of nylon sleeves and suitable fasteners at 300mm centers. Then suspend the Anutone Skelet MT15W36 MainT with flange width 15mm, height 32mm and length 3600mm, from the soffit slab with help of soffit cleat and wire rod with leveling spring clip at 1200mm centres. Anutone Skelet CT15W12 CrossT with flange width 15mm, height 26mm and length 1200mm is interlocked into the pre-cut slots in the Main T15 at 600mm centers in the perpendicular direction to the Main T15. Finally Anutone Skelet CT15W06 CrossT with flange width 15mm, height 26mm and length 600mm are interlocked into the precut slots in the CT15W12 CrossT in direction parallel to the Main T15 to result in 600x600mm module. Anutone Subtex Nubby square edge of size 595x595x15mm shall be placed into the grid size of 600x600mm. Ensure arrow marks behind the tiles are oriented in one direction to achieve uniform shade.Optional: The system is backlined with the acoustical infill Anutone SynthPF 10x25 Technical Parameters • Fire (Class) – 1 & P • Acoustics – NRC 0.9 (For E900 Mounting) • Thermal conductivity (W/mk)– 0.066 • Climate (°C, RH) – 40, 95 • Light reflectance (%) – 85 • Green (VoC, RC %) – Low, 35
