For application in BAL zones, the G2500N can be enhanced with an ember guard crafted from non-combustible, corrosion-resistant materials such as steel, bronze, or aluminium mesh, ensuring maximum safety. The mesh aperture conforms to Clause 3.6 of AS3859:2018, with a maximum allowable opening of 2 mm.
VENT Systems specialises in ventilation and internal moisture management. Any guidance regarding the G2500N and its ember guard should be considered alongside the latest version of AS 3859, the National Construction Code, and any local regulations. It’s essential to collaborate with building certifiers, fire engineers, or specialised bush fire consultants to ensure compliance and safety in all applications.
