Also known as turbine vents, whirlybirds are a semi-mechanical vent system installed on the roof to help eliminate the heat from the ceiling cavity.
How does Whirlybirds work?
The Whirlybird comes in a form of a cylindrical dome with fins that spins in the wind, creating a vacuum which sucks up the air in a roof cavity. It comes in two varieties: active and passive. Active vents are mechanically-driven and are easier to use as they turn continuously regardless of wind speed, resulting in a permanent vacuum whilst the passive vents require wind for the turbine to work.
Some of the benefits of installing whirlybirds:
- Heat reduction
Vents such as whirlybirds are designed to serve an incredible job of heat reduction. Its rotating effect forms a vacuum sucking up warm air. Once enough heat is removed, your roof will produce cooler air, giving you sufficient ventilation.
- Improved circulation
Whilst it is known for its cheap and easy installation, whirlybirds can also provide excellent circulation. This simple technique is highly capable of extracting high temperatures from your roof, allowing the air to circulate better.
Most homeowners spend tons of money on utility bills, most especially during summer season, as they are forced to use their air-conditioning units round the clock. Installing whirlybirds can be a great alternative. These vents help ensure that the air quality remains normal, keeping you from an increase in monthly utility cost.
- Fits all kind of roofing
Whatever your choice of specifications is or whether your roof is tiled or metal, you’ll surely find the type that will suit your needs as these vents are available in wide range of colours.
