Wind driven roof vents will pull more air from the attic but only when the wind is blowing.
Power roof vent vs turbine.
So let s take a look at the differences between the ridge vent vs.
A ridge vent as the name indicates is located at the ridges where your roof peaks and runs along the top of those ridges.
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.
Roof vents help keep your home cool prevent moisture problems and generally encourage healthy airflow.
Most of the time this is not productive as a ridge vent will compete with a solar fan or a roof turbine will detract from a ridge vent.
Flat roof vents have no moving parts to break or squeak but don t vent as much air as wind driven vents.
Also an active roof vent should not be within 10 20 feet of a passive vent if you decide to add or change your attic ventilation.
Compared to turbine vents ridge ventilation blends very well with the design of your roof hence your home.
Roof turbine s wear out lose their functionality.
You should not mix active and passive ventilation systems.
Gable vents do offer some benefit but are less efficient than other forms of attic vents and mostly aid airflow for only a portion of the attic space.
A ridge vent runs across the top of the roof s peak.
Turbine vents are those ice cream cone looking vents that turn in the wind using a series of vanes like a weather vane allowing warm moist air to escape at the top of your roof.
Turbine vents use outside wind to power the spinning vent and allow airflow into and out of the attic.
All aura gravity ventilators are made of rust free aluminum.
Two types of attic ventilation vents compared turbine vents roof with turbine attic vent.
Turbine vent two of the most popular styles.
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.
A turbine has a series of vanes that spin as wind passes through them.
Air movement in the attic helps prevent moisture buildup on rafters and on the bottom of roofing materials.
Picture above shows both roof vents a rotary turbine vent on the left and an aura gravity ventilator on the right with curb mount flanges.
A roof turbine can be made of galvanized steel that rusts as shown above.
In summer air movement helps rid the attic space of.
