Acoustic raft made of metal for core-activated concrete ceilings

dur-SOLO ACTIVE was developed for use underneath core-activated concrete ceilings. The acoustic raft has specially developed functions that impair the thermal conductivity of the concrete ceiling much less than conventional ceiling rafts. This ceiling is especially good at absorbing medium and high frequencies. 

  • ideal for improving room acoustics
  • easy to assemble and disassemble
  • thermally conductive gel and aluminium rails for improved climate action
