Whirlybird FAQs
How many whirlybirds do I need?
It depends on your roof size and cavity volume — as a guide, one whirlybird per 90m² of roof space is typical. We’ll assess this for you.
Do whirlybirds need power?
No — they’re wind-driven and require no electricity, so there’s nothing to wire in or maintain.
Are whirlybirds noisy?
A quality whirlybird, properly installed and maintained, runs virtually silently.
