Professional Whirlybird Installation

Queensland & NSW Whirlybird Installation

Are you tired of paying excessive energy bills to keep cool in the summer?

Back in 2017, Australia recorded the highest energy costs in the world!

Fast forward to the first quarter of 2019, and Australia’s energy prices again reached record highs, a trend which is expected to continue with providers blaming rising coal and gas prices, and scarcity of hydro energy due to frequent droughts.

What if there was a way to significantly reduce the heat your home retains without using a single watt of electricity? That’s just one of the many benefits of installing a whirlybird can bring to your home and your hip pocket.


Cost Benefit Of WhirlybirdDo whirlybirds really work?

Let the data speak for itself. Your roof space can frequently reach 70 degrees Celsius in the hotter months. That turns your ceiling into a giant heat radiator.

It’s estimated that 25-30% of your net heat gain is coming from your super-heated roof space. Ceiling fans effectively facilitate this heat transfer, a bit like a fan-forced oven. Air conditioners give relief while they are on, but the moment you switch them off, the 70 degrees roof space carries right on pumping hot air into your living space.

Unlike fans and air conditioners, whirlybirds get at the source of the problem by expelling hot air from your roof space. This means your air conditioner doesn’t work so hard, and your ceiling fan doesn’t just keep pushing hot air around.


How can whirlybirds benefit you in the winter months?

During the winter months, your roof space is typically very dark, still, and damp. Activities like cooking and showering naturally create damp, warm air which we then pump into the roof space via extractor fans. Added to this, when it is very cold outside and warm inside, condensation forms on the inside of the roof covering, further moistening the environment. All of these factors make your roof space the perfect incubator for mildew and mould. This can lead to respiratory symptoms and allergic reactions. Whirlybirds constantly extract damp air out of your roof cavity, and as such, contribute greatly to a mould free environment during those damp winter months.

An added side effect of dampness in your roof space is that it can compromise some of the structural elements of your roof. If you have a wooden roof structure, a damp environment makes it prone to rot. Furthermore, termites much prefer damp, pre-softened timber to eat. So a damp roof space does part of the termites' job for them. For those with steel roof structures, a damp environment significantly speeds up the oxidisation (rust) process, eventually weakening the structure. Either way, a damp roof space speeds up the ageing process of your roof, resulting in premature replacement and increased expense.


How do you set up a whirlybird?

Our first recommendation on this is to use a trained professional.

A word of caution: Be sure to take all safety measures.

Before starting, take a few minutes to write a list of all potential hazards and how you intend to mitigate each one. Sadly, on average, 29 Australians die every year from work-related falls. These are not all falls from multi-story structures. 50% of these falls are actually from heights of 3 meters or less!


Where do you put whirlybirds?

For maximum effectiveness, whirlybirds are best installed on the upper part of the roof.

  • For tiled roofs; aim for the third tile down from the ridge.
  • For steel roofs; aim for less than a meter from the ridge cap.
  • For aesthetics; install your whirlybird on the least visible side of the roof, usually the side that does not face the road.

Do whirlybirds let rain in?

Whirlybirds are designed to push air out and keep the rain out. That said, be careful of cheap imitations on the market, as these may be poorly designed and manufactured, which could lead to leakages in time. Rest assured that a quality whirlybird coupled with a quality installation will not leak. Read our answer to the question "Do whirlybirds leak?" for more information.


How many whirlybirds do I need?

This depends on your house size. The average Australian home would need about 4. More precisely, 1 whirlybird is needed for every 25 square meters. So a 75 square meter flat needs 3 whirlybirds, but a 125 square meter family home needs 5 whirlybirds.


Why use Twister whirlybirds?

  • 24/7 ventilation: Most whirlybirds only spin when there is a breeze. Not so for Twista whirlybirds. The patented design draws energy from the rising warm air in the roof cavity, meaning that it can keep ‘whirling’ 24/7, windy or not. This is great news since the hottest days are often those without any breeze.
  • Bigger than the rest: Being at 420mm in diameter, Twista whirlybirds are 97% bigger than most other ventilators on the market. More size equals more heat expulsion. Twista also offers the extra-large ‘Grande’ whirlybird measuring 500mm, and the jumbo ‘industrial’ range measuring 720mm. Whatever the application, Twista is bigger than the rest.
  • Maintenance and noise-free: Due to its unique design and quality components, the Twista whirlybird is maintenance-free. It will last as long as your roof does. One special feature is that Twista uses 2 high-quality steel bearings. This greatly reduces friction, meaning that the whirlybird can spin more easily without so much as a whisper.
  • Impeccable design for Australian conditions: The Twista Ventilator Company takes great pride in both the product and their reputation. After several years in the roof construction industry, Gabriel Andrews designed the unique Twista whirlybird in 1999. In 2002 he founded the Twista Ventilator Company to bring this unique product to the market. Since then, the design has grown in popularity, developing a sterling reputation in the process.
