Beat the heat with whirlybird ventilation installation. Experience cooler internal house temperatures and improved airflow. Stay comfortable today!

When it comes to regulating the ventilation and internal temperature of a house, homeowners often rely on windows and air conditioning systems. But these solutions do not truly work together as they only negate one another. One great alternative to these systems is through a whirlybird, a type of roof vent that maximises wind power to extract hot air and moisture.

This roof vent uses a spinning turbine that is installed on the roof of a building. As the wind blows over the turbine, it causes the turbine to spin, creating a suction effect that draws hot air and moisture out of the roof cavity and exhausts them outside the building. This specific system can be found in residential and commercial buildings in areas with hot and humid climates.

Now, here are some ways how a whirlybird can reduce the internal temperature of a property, especially a residential building or a house.

Extracts Extremely Hot Air

A whirlybird is designed to extract hot air from the roof cavity, which is the space between the roof and the ceiling. This hot air can reach temperatures of as high as 70 degrees Celsius on hot days. By removing this particularly hot air, the whirlybird can reduce the temperature of the roof space, which can then help decrease the internal temperature of the house.

Maximises Natural Ventilation

Aside from extracting hot air, a whirlybird can also work by harnessing the natural power of the wind in extracting hot air from the roof cavity. As the wind blows over the whirlybird, it causes the turbine inside to spin, drawing hot air out of the roof cavity. This specific function creates a natural ventilation system that can reduce the house’s internal temperature.

Improves Insulation

By reducing the temperature of the roof cavity, a whirlybird can likewise improve the effectiveness of insulation. Insulation works by slowing down the transfer of heat from the roof to the ceiling. However, if the roof cavity is hot, it can reduce the effectiveness of insulation. By drawing out hot air from the roof cavity, a whirlybird can improve the effectiveness of the insulation, which can cut down the temperature of the house significantly.

Controls Property Moisture

A whirlybird does not only extract hot air, maximise natural ventilation, and improve insulation, but it can also help control the moisture levels in the roof cavity. Moisture can build up in the roof cavity due to condensation or leaks, leading to mould growth and other problems. By ventilating the roof cavity, a whirlybird can reduce moisture and prevent moisture-related problems from occurring, which can often lead to damage to structures.

Improves Air Quality

A whirlybird can improve the house’s air quality by removing stale air and replacing it with fresh outside air. It then reduces the concentration of pollutants, allergens, and other contaminants, which can improve respiratory health and overall well-being. The internal house temperature may not be reduced with this functionality, but it can ensure the comfort of everyone.

A whirlybird can be an effective way to reduce the internal temperature of a house by extracting hot air from the roof cavity and replacing it with cooler outside air. It operates using natural wind power, does not require electricity, and can help to improve insulation, control moisture levels, increase comfort, and improve air quality. All these functions and benefits make a whirlybird unit a worthwhile investment for any homeowner.
