Whirlybird Ember Guard – 250mm

250mm Whirlybird Ember Guard – Bushfire Protection (AS3959 Compliant)

Protect your home from bushfire embers with this 250mm Whirlybird Ember Guard, designed to significantly reduce the risk of bushfire embers entering the roof space through your whirlybird vent during a bushfire.

Manufactured from high-quality 304 stainless steel, this ember guard is corrosion-resistant, durable, and suitable for long-term outdoor exposure in harsh Australian conditions. It is specifically designed to fit standard 250mm whirlybird roof vents and helps your roof ventilation system comply with AS3959 bushfire construction requirements.

During bushfires, embers are one of the leading causes of home ignition. Roof cavities are particularly vulnerable, and unprotected whirlybirds are a known entry point. Installing an ember guard is a simple, low-cost home hardening measure that can dramatically improve bushfire resilience.

Designed by an Australian bushfire firefighter and backed by over a decade of real-world use. Learn more about the design history of the original whirlybird ember guard →
