HOW DOES the Phonic Acoustic flush box ACHIeVE ACOUSTIC PERFORMANCE?
The Phonic Acoustic Flush Box has the addition of an outer flange, designed to compresses to the plasterboard. This limits air gaps that cause sound leakage while damping vibration in the flush box.
For higher rating wall systems do I have to do anything different?
The Phonic Acoustic Flush Box does not compromise the acoustic performance of any acoustic rated plasterboard system and will maintain rating for all wall systems.
Why use the Phonic Acoustic Flush Box?
Other acoustic/fire Flush Boxes can be messy to install and often require silicon products for either fire or acoustic performance. Our Phonic Acoustic Flush Box is a simple install, user-friendly product that will save on install time and doesn’t require any additional products to achieve the fire and acoustic performance required.
How does the fire rating work?
The Phonic Acoustic Flush Box has a intumescent pad installed; the intumescent material expands when exposed to fire and covers up all the holes providing a tested system for up to 60 minutes. Tested to AS15.30.4:2014 and AS4072.1:2005.
Can the Phonic Acoustic Flush Box be used for lights and power points as well as back-to-back applications?
Yes. These Phonic Acoustic Flush Boxes (PFB) discreetly replace any standard flush box. The PFB can be used back-to-back but a minimum 92mm stud is required to fit the boxes into the wall cavity.
