Description :
The EGWS have Dowel arrangement at side face for rigid and seamless fixation. The Panels are mounted on a Grid system by using "Z" clips and screws in order to avoid sagging. Black Acoustic fleece adhered at the back of the wooden slat to enhance acoustical properties.
Installation :
The EGWS Panels are to be fixed on GI 'Z'clamps made out of GI sheet of size 30 mm x 30 mm collar and 50 mm high to match with the installed GI frame. The 'Z' clamp is installed on a 'U' channel grid of size 50 x 32mm thick made out of GI sheet, 0.5 mm thick, ISI mark. The grid size will be 600 x 900mm fixed to wall using all screws of Stainless steel. Cavity of grid shall be filled with Tissue fiber paper laminated density 64 kg/cum with physical properties confirming to IS:8183 / IS:3144 and Shot content retained on Sieve - Type test (Ts2) as per ASTM C1355. The wooden acoustic panel fixed on GI Channel grid as mentioned above shall be the final finish.
