Windmaster Whirlybird from Edmonds
The Windmaster Whirlybird is probably the best known product name in Edmonds line of roof whirlybirds. There is waste range of whirlybirds in the Australian roof ventilation market. The Windmaster Whirlybird might be the benchmark for roof whirly birds in general.
Windmaster Whirlybird – Design and Purpose
The Windmaster is like other whirly birds, designed as a wind driven turbine ventilator to exhaust heat and condensation from a roof space.
Like other roof whirlybirds it is designed for simple roof vent installation. What sets the Windmaster whirlybird apart from other whirly birds is the light wight aluminium construction – and the wide range of colours available.
As a general rule – the larger the diameter of the whirlybird – the more air it will be capable of removing. For domestic whirly birds the 300 mm is at the larger scale of the spectrum. However, there are limits to what can be achieved with the classic design of wind driven turbine ventilators.
Firstly, these limits are defined by the wind available to make the roof whirlybird spin. Secondly, by the temperature difference between the roof space and the outside ambient temperature.
There is a huge range of roof whirlybirds available in Australia. If you drive through the suburbs of most Australian towns you will see roof turbine ventilators spinning on a great many roofs.
Whirly birds have been a part of Australian roofs for a very long time. So long that a Google search won’t even reveal, who invented them! Not even how long they have been around!
What will you find? A lot of articles discussing whether Whirlybirds still deserve to be as popular as they are!
In our opinion – there are better whirlybirds alternatives around. These products have adapted to current requirements and expectations by incorporating new technology!
However, it is easy to see the appeal of roof whirlybirds:
Easy Roof Vent Installation & No Energy Consumption
Easy Roof Vent Installation and zero energy consumption has always been the main arguments for installing roof whirlybirds! to try to combat the build up of heat in Australian roofs.
Solar whirlybirds represent an even easier roof vent installation than standard whirlybirds. They incorporate their own solar panel and therefore don’t consume any energy either. The main difference is is their ability to move large amounts of air – regardless of wind and temperature.

New Airflow Capacity Benchmark
The Solar Whiz roof ventilator was introduced to Australia in 2010 and has given the Windmaster Whirlybird a run for its money.
Edmonds, who manufacturers the Windmaster, does not publish its airflow capacity, however the average wind driven roof ventilator moves approx 100 cubic meters per hour at 12 km/h winds.
The Solar Whiz domestic range offers units with capacities from 700 cbm/h to 210 cbm/h.
Please read on here, if you would like to learn more about how the Solar Whiz whirlybird compares with conventional whirlybirds, like the Windmaster Whirlybird, which for many decades have been sitting on a dominant portion on Australian roofs.
