Offices require good control of reverberation to eliminate excessive reflections for improved privacy and comfort. Closed plan office with partitions terminating at the ceiling line will require high STC ceiling panels for room to room privacy.

For general office and open plan offices designs and call centres with lower reverberation time requirements we recommend our ISO class A absorbers, Triton 25, Triton 50, Triton Duo 35, Triton Duo 60 ceiling absorber panels.

For meeting rooms with parallel walls we recommended that at least one wall be lined with our Fabwall stretch fabric acoustic panels to prevent flutter reflections and reduce reverberation.
