How It Works
Wildfire spreads through three primary mechanisms: Embers, radiant heat, and direct flame contact.
Most homes are not lost because the fire front reaches them - they are lost because wind-driven embers ignite vulnerable areas around the structure.
Structure Defence systems combine FireSmart landscaping practices with strategically placed roof ridge sprinklers to create a humid protective zone aound your structure.
This approach reduces ignition risk and increases the liklihood your home can withstand ember exposure during a wildfire event.
Step 1
Reduce the Fuel Around the Home
The first layer of protection in FireSmart preparation.
Reducing combustable materials around the structure dramatically lowers the chance that embers can start fires close to the home.
Immediate Zone (0 - 1.5 meters)
This area should contain no combustable materials.
Typical improvements include:
Removing bark mulch, wood piles and dry debris
Replacing vegetation with rock or non-combustable ground cover
Keeping decks and gutters free of debris
Using ember-resistant vents and materials
Intermediate Zone (1.5 - 10 meters)
This area focuses on reducing available fuels and slowing fire spread.
Recommended practices include:
Pruning lower branches on trees
Spacing vegetation to prevent fire ladders
Replacing evergreen shrubs with deciduous plants
Maintaining a healthy green lawn and irrigated landscaping
Step 2
Create a Humid Protection Zone
Once fuels are reduced, the next layer of defence is increasing humidity around the structure.
Structure Defence systems use roof-ridge mounted sprinkler placement, designed to create a “humid bubble” around your home.
The system works by:
Wetting roof surfaces
Increasing localized humidity around the structure
Dampening surrounding vegetation and fuels
Reducing the ability for embers to ignite material
When operating, the sprinklers create a protective moisture layer that can significantly reduce ignition potential.
During wildfire events, embers can travel kilometers ahead of the fire front.
The humid zone created by the system help counter by:
Wetting surfaces where embers may land
Increasing moisture in surrounding fuels
Cooling roof and exterior surfaces
Reducing ignition probability
Even under heavy ember casting, maintaining moisture around the structure dramatically improves survivability.
A Layered Defence Strategy
Wildfire resilience is achieved through multiple layers of protection.
Structure Defence combines:
FireSmart landscaping practices
Professional system design
Roof and perimeter moisture coverage
Ember ignition reduction
Together, these elements create a defensible environment around your home.
Built by Firefighters
Our systems are designed using real wildfire behaviour knowledge and practical suppression experience.
The goal is simple:
Reduce ignition potential and increase survivability of your home during wildfire events.
