The Phonic Acoustic Flush Box maximises the acoustic performance of mounting switches and power outlets.

Phonic Acoustic Flush Boxes (PFB) have been fully tested to maintain the acoustic rating of a wall. PFB has the addition of an outer flange, designed to seal to the wall lining. This limits air gaps that cause sound leakage while damping vibration in the flush box.

Testing shows that the use of our PFB maintained the overall system acoustic performance of a test wall. Canterbury Acoustic Testing Services. Report 2022-227 CATS Test Standard: ISO 10140-2:2010.

PFB has an intumescent pad installed; the intumescent material expands when exposed to fire. Tested to AS1530.4:2014 and AS4072.1:2005, for fire rating.
