How to use ember mesh to fireproof your home

Time to get meshy!

We're no stranger to bushfire danger here in Australia and NZ. That's why it's so important to make sure your home is fitted with all the recommended fireproofing features. One of these is ember mesh – and Jack's here to help you install it!

Did you know that if you live in a bushfire-prone area, you’re actually required by law to cover openings and cavities? That’s because wind can carry bush fire embers, including leaves, twigs and other garden rubbish, into your home through small gaps.

In fact, 85 per cent of homes that burn down during bush fires are started by windborne embers, not by contact with the fire itself.

Examples of these types of gaps include:

  • Vents and weep holes
  • Eaves and ventilation openings
  • Openings in subfloor supports, such as verandas, decks, steps, ramps and landings

An effective ember guard should be non-combustible, have no more than 2mm gaps, and be made of corrosion-resistant material.

Our Jack Ember Mesh (190mm x 4m) complies with Australian Standards AS3959 for new builds. This relates to the six levels of BAL Bushfire Attack Levels – see table below. There are different ember mesh requirements for each level. The recommendations also apply to all dwellings in bushfire-prone areas.

The mesh can be used to cover any holes or gaps and is easily cut to size.

Your step-by-step guide

  1. Locate any holes or gaps

    Locate those vents…underfloor, around eaves and wall gaps, where bush fire embers, including leaves or twigs can enter.

  2. Measure and cut

    For flat openings like air vents and gaps, measure the size, then cut the ember mesh with your wire cutters to cover the entire area.

    Measure…and cut.

  3. Trim to fit

    Hold the mesh up to the opening and then trim to size if needed.

    Trim to size.

  4. Screw and secure

    Grab your screwdriver and make holes in each of the four corners. Then fasten into place.

    Hold and screw – position your fasteners…

    Knock them in.

    What a magnificent mesh!
