BAL-FZ Compliance
Our BAL-40 stainless steel vents are compliant with BAL-FZ when installed correctly in accordance with the BAL-FZ standards.
Click Here to download the construction requirements for BAL-FZ under Standards Australia AS3529:2018.
The relevant sections are:
- 9.4.3
- 9.6.1
- 9.6.5
- 9.6.6
The essential requirement for compliance is found in 9.6.5. To be compliant a sealant must be used when installing the vents to prevent gaps. The sealant used "shall be sealed with mineral fibre at the roof to prevent gaps. The material used to seal the penetration shall be non-combustible."
Airflow Through Bushfire Mesh
These vents include removable cinder mesh inserts with 2mm openings.
To be BAL-40 compliant, this cinder mesh insert must be installed. Please note that some pressure loss will occur from the added resistance caused by the cinder mesh, which may cause a reduction in airflow. We recommend a high quality centrifugal fan with a strong pressure curve, such as our AC and EC motor centrifugal fans, to minimise this pressure loss.
If you are not in a bush fire prone area, this cinder mesh can be removed, which will increase the airflow through the vent.
