EMBER ATTACK PROTECTION
Whites EmberMesh Stainless Steel Guard covers openings and gutters to prevent the entry of burning embers.
It is corrosion resistant 316 Grade Stainless Steel wire with powder coated finish. Complies with Standard AS3959 – 2009/2011.
Protect Ember Entry Points
The updated standard AS3959 requires any gaps greater than 3mm to be sealed by a mesh with a maximum aperture of 2mm, to reduce the chances of embers settling. Examples are:
- Gaps between and under corrugated roofing
- Vents and weep holes
- Screens for windows and doors
- Eaves and ventilation openings
- Openings in sub floor supports, such as verandas, decks, steps, ramps and landings
Ember Mesh Stainless Steel Guard can also be used for gutters, to stop the build up of leaves and debris. Ensure all gaps between gutter and roofing are covered.
About Ember Attack
Burning twigs, leaves and debris create embers which can be easily carried by wind. An ember attack occurs when these embers are carried onto a home or other structure. Embers vary in size and can be small enough to enter a building through a roof space, windows, doors, vents, eaves and decks, to name a few.
