To keep bushfire out of the house this summer,

make and mend, paint and fill.

Houses are rarely destroyed because approaching flames burn the cladding. Ignitions almost always start inside, from ember penetration. Most houses then burn from the inside outwards, frequently starting in the roof/ceiling space, with frame and cladding burning last.

Clean out the roof void! If you don’t have an inspection trapdoor, make one. 
Insulate above and below rafters. 
This is an extremely vital bushfire-protection job.

·        Neither embers nor flame can ignite your house if you have roof sprinklers.
- Have low flow sprinklers. And enough water to run them.
      ·        Embers from a bushfire can’t penetrate roofs if it is of continuous metal sheeting.
·        Embers can’t penetrate corrugated iron roofs if you secure loose sheets & fill nail holes.
·        ·        Sparks and embers can’t penetrate cracks if you fill them with a fire resistant expandable epoxy-type filler.
·        Sparks and embers can’t penetrate vents if you cover them with metal flywire
·        Burning debris can’t ignite cladding if you give it a low non-flammable surround.
·        Embers can’t ignite under the house if it’s a concrete slab.
·        Embers can’t ignite under the house if you enclose a raised sub-floor area
- Metal fly-wire is effective.
·        Neither radiant heat nor embers can crack windows if they’re shuttered or screened with metal fly-wire.
·        Embers can’t ignite floors if they’re slate, tile or brick.
- And they have a hard job starting on quality linoleum.
·        Embers can’t ignite curtains if they’re pure wool or of heavy quality sun-block fabric.

Insulate roof, wall cavity and beneath floor joists with mineral wool, fibreglass batts or aluminium foil laminate.
