Junction 24, a brand-new luxury apartment in Kew, Victoria, was able to meet the fire protection requirements as mandated by BCA by installing a range of products from Greene Fire.
Consisting of eleven apartments in configurations of two to four bedrooms, the building features Vii cabins and MicroLouvre attenuation screens from Greene Fire.
Clause C3.2 of the BCA requires openings in external walls that need to have an FRL and are located within 3m of a property boundary in accordance with Clause C3.4 of the BCA; if wall wetting sprinklers are used, they should be located externally.
Clause C3.4 of the BCA indicates that when protection is required, windows must be safeguarded with internal or external wall-wetting sprinklers: –/60/– fire windows that are automatically closing or permanently fixed closed; or –/60/– automatic closing shutters.
Designed by 2 Scale Design Pty Ltd, Junction 24 was built by LJA Constructions Pty Ltd with Dobbs Doherty serving as the fire engineer.
Greene Fire solution
Since the windows on the western side of the apartments were within 3m of the property boundary, each opening had to be fire separated by -/60/- fire rating as required under BCA Clause C3.4. It was decided to design and install Vii cabins and MicroLouvre attenuation screens for all external openings within the 3-metre boundary.
Vii cabins are installed around windows located in close proximity to property boundaries. Being fusible link activated, the cabins do not require power or an alarm system to deploy the curtains. Vii cabins provide two hours of fire integrity to AS1530.4 and AS1905.2 requirements. All Vii cabins are gravity fail safe systems closed with a fusible link.
MicroLouvre attenuation screens are tested according to the procedure outlined in AS15304 Appendix B.7 and AS1530.8.1 as confirmed in the CSIRO Report EP164870. Also used as a fire engineered solution to protect openings close to property boundaries, MicroLouvre attenuation screens can fit into any shape and size of window.
Key benefits of MicroLouvre attenuation screens include additional privacy screening to address overshadowing in bathroom and stairway; solar shading protection without impeding external visibility; compliance for bushfire up to BAL-40 and BAL-FZ; 49.4% heat attenuation; and cost effective solution compared to wall wetting sprinklers.
