Open metal ceiling system made of individual panels

dur-SOLO type 4 is the most variable raft ceiling from durlum. Assembled down the longitudinal sides from any desired number of panels, there are hardly any limits to its design. Their weightless character is underlined by the invisible sub-structure integrated in the raft. Among other things, dur-SOLO Type 4 is suitable for use as a cooling ceiling in office buildings or for renovation projects. 

  • ideal for improving room acoustics
  • optionally combinable with core-activated concrete ceilings
  • can be dismantled easily and without tools
