Twista Whirlybird

Born under the brutal Australian sun, built for it too. Twista is a 100% Australian-owned company that’s been crafting roof ventilation systems tough enough to survive — and thrive — in some of the harshest conditions on earth.

For over 30 years, we’ve been the quiet force behind cooler homes, drier roofs, and lighter energy bills across Australia. With more than 353,500 installations (and counting), Twista has earned trust not just from everyday homeowners, but from big names like Westfield, KFC, and Lendlease.

We don’t believe in shortcuts. Every Twista ventilator is built using premium-grade materials, hardened steel ball bearings, and designs tested against real-world chaos — scorching heat, driving rain, even the occasional hailstorm. Our ventilators don’t just spin; they work overtime to drag out hot air, moisture, and stale pockets of air without chewing through electricity. No gimmicks. No apologies.

We offer both DIY kits and professional installation around Sydney — and we back every ventilator with a rock-solid 10-year structural warranty, plus a 12-month installation guarantee if we do the fitting ourselves.

At Twista, we’re proud to keep roofs cooler, homes healthier, and energy bills lower — all without relying on fragile tech or expensive power bills. Just simple, reliable engineering that keeps working year after year. That’s the Twista way.

We’ve been at this for over three decades. Not sitting in boardrooms — up on roofs, in the heat, testing, tweaking, and installing ventilation systems that actually stand the test of time. Since the early '90s, we’ve grown from a small Sydney-based outfit into a nationally recognised name in passive ventilation, trusted by everyone from suburban homeowners to major commercial developers. Whether it’s 45°C summers or torrential downpours, our products are out there spinning, cooling, and staying strong.

Our team’s strength comes from a mix of hands-on trade experience and deep technical knowledge. From metal fabrication to aerodynamics, our crew includes qualified roofers, engineers, and installers who know how to turn steel and airflow into a long-lasting solution. More than degrees on a wall, our real education has come from 30+ years of solving problems — one roof at a time.
