As property values throughout Australia skyrocket, we are seeing an increasing trend for developers to optimise the size of buildings placed on an allotment. Buildings are being constructed closer together sometimes in very close proximity to boundary lines. This trend towards supersized structures has created challenges for planning organisations and certifications trying to maintain the safety and stability of Australia’s building stock and the wellbeing of occupants. One challenge which emerges through the construction of buildings close to boundary lines is how to stop the spread of fire in the event that the unthinkable happens and a building catches alight.
The National Construction Code (NCC) sets our guidelines for the protection of buildings from the risk of fire from adjoining properties. The NCC requires openings in external walls be protected from fire when the walls are in close proximity to adjoining property boundaries. Openings that are less than 3m from a property boundary or within 6m of another building in the same allotment must be protected. One method is the use of fire attenuation screens.
What are fire attenuation screens?
Fire attenuation screens are designed to resist radiant heat flux and are tested in accordance with AS1530.4:2014 (Appendix B7) to determine their effectiveness. Fire Attenuation Screens applied to window openings can be used as part of a performance solution to satisfy the requirements of the NCC. When incorporated as part of a fire protection solution, Fire Engineers must specify products which will satisfy the specific requirements of the site for Fire Attenuation.
Amplimesh® OneFrame and Supascreen® with our high tensile 316 marine grade stainless steel mesh have been tested in accordance with AS1530.4:2014 to determine its fire attenuation rating. The Supascreen® product was subjected to an irradiance heat of 40kW/m2 for a period of 121 minutes. Probes were used to measure the radiant heat which passes through the screen. This outcome is reported as the screens attenuation rating, being the percentage of heat that is blocked by the screen.
Approved to: AS1530.4 – 2014, Appendix B7
Radiant Heat Flux: 40kW/m2
Duration: 121 Minutes
Result: Attenuation of Oneframe when exposed to a nominal 40kW/m2 was 41% (radiant heat transmitted) – meaning a reduction of 59%.
Test Report: FSZ 2155 & FCO – 3145 Rev A
