Whirlybirds are a popular way to ventilate buildings, but just how effective can they actually be? In this blog, we’ll break down a few key benefits of whirlybirds to help you determine the best course of action for your home or office space.
Energy-Efficient
Whirlybirds can improve the overall energy efficiency of a building, as they don’t require any electricity or other power source to operate. By keeping spaces cooler, they reduce the load on air conditioning systems, which can lower your energy bill. With no operational costs and reduced power costs, whirlybirds are a fantastic money saver for many home and building owners.
Prevents Moisture
Moisture can cause a variety of problems in your home, including mould growth, rot and structural damage. By ventilating your building, whirlybirds help prevent moisture from accumulating, reducing the risk of these issues.
Improved Air Quality
By removing hot, stagnant air and replacing it with fresh outside air, the levels of indoor pollutants such as dust and allergens are significantly reduced, which can be especially beneficial for people with allergies or respiratory issues. Moreover, whirlybirds can remove smoke, odours and industrial fumes for improved air quality.

FAQs
What do whirlybirds do?
Whirlybirds remove hot air and moisture that is trapped within your roof cavity and prevents the build-up of fumes, stale air and damaging condensation. In the hot Aussie climate, whirlybirds are a great way to keep a space cooler all year round.
Are whirlybirds noisy?
A functioning wind-powered whirlybird shouldn’t be making noise, so a noisy whirlybird is likely in need of repairs.
Do they work without wind?
Whirlybirds are designed to function in even the lightest winds, although they’ll work most effectively in more powerful conditions.
Are they weatherproof?
Whirlybirds are designed to withstand high winds and rain, meaning there should be no leaking in your home. A leaking whirlybird indicates damage and may need to undergo repairs.
Do they only work in hot weather?
Whirlybirds are practical year-round; their purpose is to ventilate your building by extracting heat and managing moisture. This reduces the risk of mould and mildew build-up, which is important even during colder periods.
How many whirlybirds do I need?
We recommend installing one whirlybird per 90m2 of roof space to maintain optimum air quality in your home.
Where will they be installed?
It’s usually best to install whirlybirds on the highest ridgeline of a roof to maximise effectiveness; this is because hot air rises naturally to the highest point, and often exposes the whirlybird to unobstructed winds. However, if a particular area of your home is more susceptible to moisture build-up, you may prefer to have a whirlybird installed in that area.
