Acoustic Panelling Systems

The NSL Acoustic Wall Lining System has been developed to cater for the diverse range of constructional and performance specifications required for both the Industry and commercial market.


The system is available in four thicknesses: 25, 50, 75 & 100mm sections. Minimum sizes available to suit most requirements up to a maximum size only limited by potential handling problems.

Design Features

Acoustic wall lining is constructed from perforated sheet metal with the infill sealed behind a resin bonded tissue facing to prevent particle migration. The infill is a controlled density mineral wool or glass fibre and shall is inert, non-hygroscopic, rot proof and vermin proof with a Class ‘1’ rating for spread of flame in accordance with BS476:Part 7. A separate unique peripheral retaining frame provides inherent structural rigidity for the Acoustic Panels.


Acoustic wall lining, when specified, can be finished in a high quality polyester powder paint colour from the BS4800-1982 or RAL-F3-1984 colour ranges. All acoustic wall lining and derivatives are delivered to site with the appropriate protective packing, dependent upon the type of finish specified.

Typical Applications

For use in various capacities including factory production areas, chiller compounds and commerical plantrooms. With the correct treatment the wall lining system is suitable for external applications as well as standard internal use.
