Description

Acoustic wall cladding made of perforated metal for targeted room-acoustic optimization, ideal for retrofitting in existing buildings. A seamless transition from ceiling to wall in identical appearance is possible when the wall is combined with a FURAL metal ceiling system. It can be printed individually via COLORPRINT and thus used as a visual design element. 20 tested configurations with different specifications.
