Turbine Roof Vents How They Work

The popular ridge and soffit ventilation systems and the traditional metal pot vents are also passive ventilation systems.

Turbine roof vents how they work.

Cool air in hot air out attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents. While a turbine looks a little complex at first glance it s actually very simple. Intake vents located at the lowest part of the roof under. The intake should be installed at the soffits or blocking where the walls meet the roof.

Wind driven roof vents will pull more air from the attic but only when the wind is blowing. All things being equal wind driven turbine vents also known as a whirlybird roof vent do move more air than flat vents but only when the wind blows. How do turbine roof vents work. A turbine vents spins with the slightest breeze.

A ridge vent runs across the top of the roof s peak. The same steps can be used when doing a whirlybird roof turbine vents. Turbine vents use a combination of wind and convection to extract stale hot air from inside your home and replace it with the cool clean air from the outside. Flat roof vents have no moving parts to break or squeak but don t vent as much air as wind driven vents.

Whirlybird roof turbine vents are as easy to install as turtle vents and are one of the most popular ways remove hot air out of the attic space. Dependable construction has made a video on how to replace a turtle vent on a roof. A turbine has a series of vanes that spin as wind passes through them. It houses a circular fan that s very sensitive to breezes.

A turbine is installed directly on the top of a roof and uses wind power to suck hot and humid air out of the attic. Unlike turbines this venting style does not have any moving parts. A small 12 inch diameter turbine vent with a constant wind speed of 5 miles per hour mph can remove 347 cubic feet of air per minute cfm from the attic space. When the wind blows the right way it turns the fan which in turn draws up air from the attic and disperses it.

Because warm air rises up the wind powered vents with their spinning action tend to suck the air outside. A turbine vent is a passive ventilation device. Much like a window this round vent is powered by the wind.
