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 closed plan offices designs we recommend our Knauf-Danoline™ range of perforated acoustic gypsum ceiling systems. Available in economical accessible reveal and concealed edge grid and tile designs as well as screw fixed sheet linings they provide good levels of durability and acoustic control.
Available in 3 perforation styles to suit aesthetic and non perforated panels for borders and over partition heads for room to room privacy.
Knauf-Danoline™ perforated gypsum ceilings provide an attractive perforated aesthetic and are a healthy and durable alternative to traditional mineral fibre ceilings.

For open plan office space 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 Sound Soft high impact/ tackable stretch fabric acoustic panels to prevent flutter reflections and reduce reverberation.

For premium office space we recommend our ATKAR™ brand perforated decorative acoustic panels for wall panels, column covers, quiet rooms, receptions, feature ceilings.
