   Do Whirlybirds need eave vents?

   • Unlike metal roofs, there isn’t as much need for eave vents. Whirlybirds are designed to spin in even in the lightest winds. Whirlybirds extract hot air via two ways; convection and creating a vacuum. The vacuum potential is driven by the wind speed and drawing heat out of the roof space. The stronger the wind, the more powerful the extraction.

   • To be honest, they are hideous to look at compared to the more sophisticated ridge vents. Under the right conditions, a whirlybird can move considerably more air than a ridge vent. A turbine vent will rotate at even a small wind which sucks out the air from the attic. The more the wind the more powerful will be its venting.
