Bushfire Mesh

Stainless Steel Bushfire Mesh is part of the solution for your bushfire protection.

Stainless Steel Bushfire Mesh protects homes and buildings in bushfire prone areas against ember attack and radiant heat.

AS3959 Amdt 3 Construction of buildings in bushfire-prone areas
Various sections of AS3959 Amdt 3 requires a mesh to be used for screens or closing gaps greater than 3mm.

SSWM Bushfire Mesh Ember Stop range has been independently tested and meets the physical properties of AS3959 Amdt 3.
✔ Mesh with max aperture of 2mm
✔ Corrosion resistant steel
✔ Non combustible

SSWM bushfire mesh can be used in all applications:
– That requires gaps of greater than 3mm to be closed by a mesh (as above)
– The gaps between the perimeters of the mesh and the building element that it is fitted does not exceed 3mm

BAL 12.5 -FZ
SSWM bushfire mesh can be used to meet the requirements of AS3959 amtd 3 for BAL 12.5 -FZ, where mesh is referenced and if the prescribed construction requirements are met.

Product Specifications
Our range is designed so there is a mesh to suit any application, from soft to rigid.

The primary use of the mesh is for bushfire protection, how and where you install your mesh will determine which mesh is most appropriate.

What is Ember Attack?
The most common way that houses catch fire during bushfires. Research has shown that this is the cause of 80% of houses lost. Embers can enter gaps in building as small as 1.8mm, igniting timber and other materials such as leaf litter.

  • Embers are burning twigs, leaves abd pieces of debris
  • Ember attack occurs when twigs and leaves are carried by the wind and land on or around houses
  • Ember attak is the most common way houses catch fire during bushfires
  • Embers can land on top of debriss in your gutters and set fire to your house
  • Ember attack can happen before, during and after bushfire

Stainless Steel Bushfire Mesh- More Information

In the aftermath of Black Saturday which devastated parts of Victoria in 2009 many people are reassessing and increasing their bushfire protection of their properties.

The introduction of the building regulations that require consideration of bushfire protection as specified in the Australian Standard 3959-2009 (AS 3959) ‘Construction of buildings in bushfire-prone areas’ give those that are rebuilding or renovating their homes clear direction of how to protect their homes against burning embers, radiant heat or flame generated by a bushfire.

The four ways bushfires can destroy homes

-ember attack
-radiant heat
-direct flame contact
-fire driven wind

Ember attack is the most common way that houses catch fire during bushfires. Research has shown that this is the cause of 80% of houses lost. Embers can enter gaps in buildings as small as 1.8mm, igniting timber and other materials such as leaf litter.
Radiant heat is the heat created from combustion during a bushfire. It can ignite surfaces due to heat being received from fire without direct flame contact or ember attack, dry out vegetation ahead of the fire, crack and break windows and distort and melt materials such as plastic.
Direct flame contact Occurs when flames impinge on the building. This is often from a burning item or debris. When flames from the fire front may impinge on the building this is known as being in the ‘flame zone (FZ)’.
Flame –driven Wind can be destructive as it carries embers, can cause trees to fall on buildings, can break windows, loosen roof tiles allowing embers to enter the roof space.

Planning for Bushfire Victoria – Guidelines for meeting Victoria’s Bushfire Planning Requirements (CFA)
When is Bush Fire Protection required?
The new standard AS 3959 contains six science based bushfire risk categories. The BAL system is based on the potential danger of the site and construction materials to heat flus exposure, expressed as kW/m2. In determining a sites’s BAL, the Fire Danger Index (FDI), vegetation type, distance of the site from vegetation and the effective slope under the vegetation are taken into consideration.

Bushfire Attack Level (BAL) Radiant Heat Exposure (AS 3959) Description of predicted bushfire attack and levels of exposure
BAL-LOW  Insignificant The risk is very low, radiant heat on the building is insignificant to warrant specific construction requirements, however ember attack may still occur
BAL-12.5  0 to 12.5 kW/m2 Primarily risk of ember attack; risk of radiant heat is considered low
BAL-19
12.5 to 19kW/m
Risk is considered to be moderate with increasing levels of ember attack and burning debris ignited by wind borne embers; increasing likely hood of exposure to radiant heat
BAL-29  19 to 29 kW/m2 Risk is considered high. Increasing levels of ember attack and burning debris ignited by wind born embers; increasing likelihood of exposure to radiant heat
BAL-40  29 to 40 kW/m2 Risk is considered high. Increasing levels of ember attack and burning debris ignited by wind born embers; increasing likelihood of exposure to radiant heat and some exposure to flames possible
BAL-FZ  40 kW/m2 plus (Flame contact) Risk is consdered to be extreme. Direct exposure to flames from fire front is likely in addition to high levels of radiant heat exposure and ember attack.

Retrofitting homes for increased bushfire protection
The majority of houses built in bushfire prone areas pre-date the Australian Standard AS3959-2009 ‘Construction of buildings in bushfire-prone areas’, meaning they are unlikely to reach the increased level of protection specified in the new standard.

The CFA and The Building Commission are together providing practical information on upgrading existing homes to be better protected from bushfires.

For further information on retrofitting your home refer to the following guides.
