Whirlybirds are a common sight on rooftops in Melbourne. These cylindrical domes with their rotating vents can be spotted on many panelled or sheet metal roofs because they offer numerous advantages for homes, factories and businesses in warm and humid areas.
If you don’t quite understand how whirlybirds work or what benefits they offer then it is high time to learn more about these functional roof accessories. The number of benefits they offer will surprise you.
These types of turbine vents are installed on rooftops. They can be installed on any type of rooftop including tile roofs but are more common in metal sheet rooftops because metal roofs require more ventilation and tend to get warmer when it is hot out.
These devices are wind-powered and will start rotating when the wind blows on it. They are designed to create a vacuum that extracts hot air from inside the building. The whirling can also start to rotate when there is no wind around due to the high air pressure from the warm air trapped inside your rooftop.
It can be quite mesmerising to stare at whirlybirds as they rotate, especially in warehouses where there might be no ceiling present. These turbines can offer many advantages to the building and those living or working inside it. Here is a quick look at some of the main advantages.
Whirlybirds are most common in hot and sunny areas like Melbourne because they are great heat management tools. It is common for home or building interiors to become very hot inside as the sun bakes on the roof materials. Warm air tends to rise up while cool air tends to sink.
This is exactly why the roof cavity or attic is usually the warmest part of the house. When there is no way for the warm air to escape, the warmth will keep spreading and circulating through your house until the entire area is toasty.
With whirly birds, all of the warm air is drawn up and out through the vents. This keeps the warmth from spreading through the building’s interior. It is estimated that a bunch of whirlybird ventilators can reduce your building’s interior temperature by up to 35%.
When it gets hot inside the house, we tend to turn on the fans or air conditioning unit. These electronic devices can increase your energy bill tremendously and, unless you have a solar system, they are not great for the environment.
Since whirlybirds reduce the overall temperature of your building interior, they reduce the need for cooling electrical devices. This saves a lot of energy and aids the environment.
In humid regions like Melbourne, a lot of moisture tends to get trapped inside the roof cavity. This moisture buildup can cause roof materials to rust or rot. Installing whirlybirds will allow the moisture to escape. This protects the roof materials and can increase the life expectancy of your roof.
Whirlybirds can improve the indoor air quality of buildings. Proper roof ventilation prevents mould and mildew from growing inside your roof and the turbines increase air circulation throughout the building. As a result, the indoor air quality is much fresher and cleaner.
