  • The I-LuxB is a modular 1935 x 595mm timber slatted acoustic panel which can offer very high levels of acoustic absorption due to its large open area in front of the black tissue faced absorbent material that needs to be placed behind.
  • Battens are joined using an interlocking black rear batten.
  • It is available in four standard timbers Iroko, Beech, Oak and Pine but can also be colour lacquered, painted, varnished, stained etc.
  • Unlike cheaper import imitations which require onsite lacquering to upgrade to Class0 our panels can be supplied in a Class0 Fire Rating thus saving substantial labour time.
  • The slats are connected black rear battens. Gaps can be left either visible or hidden with a black tissue faced fibre.
