raumAKUSTIKS (owner: Helge Herrmann) manufactures custom sound absorbers in Berlin for room acoustics in offices, industrial, retail, hospitality and residential settings. Every AluWall absorber is made to measure: an aluminium frame with a highly absorbent polyester core (ISO-BOND®, thermal conductivity class WLG 040, fire class B1 per DIN 4102), or a glass-wool core for the A2 variant. The visible face is a seamlessly tensioned, flame-retardant fabric in any colour, optionally printed with high-resolution digital artwork (seamless up to 300 cm). Beyond the AluWall system, the range includes acoustic louvres, transparent honeycomb sound shields, microperforated acrylic glass and acoustic curtains. Installation and planning are available throughout Germany as well as in Austria, Switzerland and the Benelux countries.
