Terms of the Trade: What Is a Turbine Vent?

Lead Image

Turbine vents are used for removing hot air from spaces, including attics. Hot air rises, but will remain trapped in a room because of a roof or ceiling if there are no vents to allow it an escape route. Turbine, or whirlybird vents, are installed on top of a roof and use wind power to suck the hot air from an attic or other room. As wind passes through the vent, a series of vanes spins, providing more air circulation than a standard vent.
