Whirlybird wind-driven ventilator systems — also known as wind vents or turbine vents — are one of the simplest and most effective ways to extract heat and moisture from commercial warehouses, sheds, attics, and roof spaces.
Built for New Zealand Conditions
Suntrenz Wind Vents are engineered specifically for New Zealand’s climate. While there are plenty of vent options on the market, we stick with what we know works best — straight-vane wind vents built with high-quality bearings for smooth, reliable, long-term performance.
We don’t need to compare or criticise competitors — the results speak for themselves. Many of New Zealand’s leading shed builders have come back to Suntrenz after trying cheaper alternatives that simply couldn’t stand the test of time.
We also offer a 15 Year Manufacturer’s Warranty!
Designed for a Seamless Fit
While we do not offer profiled flashing systems for our wind vents, the base flashings are manufactured wider than most on the market. This design is intended to eliminate the need for additional flashings, allowing the wind vent to be successfully installed using the flashing supplied.
Prior to dispatch, Suntrenz can also fold the base flashing to specified measurements upon request, making on-site installation simpler and more efficient. Wind vents are available colour-matched on request.
How They Work
As the wind turbine spins — even with a light breeze — it creates a natural suction effect that draws hot, stale air out of the roof cavity. This reduces internal roof temperatures, prevents condensation and moisture buildup, and helps extend the life of your roofing materials.
Keep Your Shed Cool This Summer
Many sheds across New Zealand become unbearably hot during the warmer months. Suntrenz Whirlybird Roof Vents provide year-round ventilation, spinning continuously even in the lightest breeze — no electricity required.
Constructed from lightweight, high-strength aluminium, they’re completely rust-free and feature large exhaust openings across all sizes to deliver maximum ventilation performance.
What they say?
Shane Morton “Great service, Good communication and the whole process from enquiry to actioning the order to install was done in a timely fashion. Very happy with the workmanship and the Whirly Birds that were colour matched to our roof making them look like they are meant to be there rather than an after thought.”
