Grooved Wooden Slates
Envirotech Grooved Wooden Slats are 16 mm thick acoustic panels made out of a high density MDF board substrate made from residues of hardwood and softwood gluing together with wax and resin under extreme pressure, with a laminated facing as per the approved shade/ species & finish. The EGWS have a width of 2420 x 575 / 128 mm and a groove size 3.2 mm at an interval of 14/28/56 mm alternatively. The thickness of the panel is 16 / 12 mm as per the requirement of the client.
.
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.
The EGWS Panels are to be fixed on GI 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 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 EGWS wooden acoustic panel fixed on GI Channel grid as mentioned above shall be the final finish.
