Wooden Grooved & Perforated HDHMR Acoustic Wall Panel System is used for auditorium side wall treatment to improve acoustic performance and provide a premium wooden finish. The system uses 18 mm thick grooved and perforated HDHMR panels with black fleece backing, fixed over a GI stud framework with mineral wool insulation, wire mesh, non-woven fabric, and calculated air gap.
The grooves and perforations guide sound into the acoustic cavity, where the fleece and mineral wool help absorb sound, reduce echo, control reflections, and improve sound clarity. The system is moisture resistant, durable, visually appealing, and suitable for auditorium interiors requiring acoustic and decorative wall treatment.

Wooden Grooved & Perforated HDHMR Acoustic Wall Panel System is used for auditorium side wall treatment where acoustic control, decorative wood finish, moisture resistance, and long-term durability are required.
The system uses 18 mm thick high-density high-moisture resistant grooved and perforated panels fixed on a GI stud framework. The panels have grooves and perforations backed with black fleece to allow sound waves to pass into the acoustic cavity, where mineral wool insulation helps absorb sound and reduce reverberation.
It provides a premium wooden appearance while improving sound clarity, reducing unwanted reflections, and enhancing the acoustic performance of auditorium interiors.
The purpose of this system is to improve auditorium acoustics and provide a clean decorative wall finish.
It helps in:
The work starts from the existing wall surface. Panel layout, levels, track lines, and design pattern are marked as per approved architectural drawings and EIC instructions.
GI top and bottom tracks are aligned and fixed. GI stud channels are installed to create a strong support framework.
Mineral Wool RB Slabs are inserted within the GI framework to improve sound absorption and insulation.
Galvanized hexagonal wire mesh is fixed to hold the insulation securely. Plain spun bond non-woven fabric is applied for air filtration and protection.
A calculated air gap is maintained behind the acoustic panels to improve low-frequency absorption, reduce vibration transfer, and control sound transmission.
Wooden grooved and perforated HDHMR panels are fixed over the prepared acoustic backing system.
Panels are aligned properly and finished with approved protective coating to protect against moisture, dust, dirt, and surface wear.
The scope includes providing and fixing of customized wooden grooved and perforated HDHMR acoustic wall panels for auditorium side walls.
The work includes material supply, fabrication, finishing, transportation, GI framework installation, mineral wool placement, wire mesh fixing, non-woven fabric layer, calculated air gap provision, panel fixing, protective coating, alignment checking, and final cleaning.
All necessary hardware, screws, fasteners, tools, machinery, manpower, staging, consumables, and installation accessories shall be included. The work shall be executed by skilled labour at all required heights as per approved architectural drawings, site conditions, acoustic requirements, and Engineer-in-Charge instructions.
