Power Roof Vent Vs Turbine

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.

Power roof vent vs turbine.

Your roof just doesn t work well without them. A roof turbine can be made of galvanized steel that rusts as shown above. 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. Roof turbine s wear out lose their functionality.

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. 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. 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. Two types of attic ventilation vents compared turbine vents roof with turbine attic vent.

Unlike turbines this venting style does not have any moving parts. 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. So let s take a look at the differences between the ridge vent vs. Compared to turbine vents ridge ventilation blends very well with the design of your roof hence your home.

Flat roof vents have no moving parts to break or squeak but don t vent as much air as wind driven vents. Air movement in the attic helps prevent moisture buildup on rafters and on the bottom of roofing materials. You should not mix active and passive ventilation systems. It is hard to tell if a house has the vents installed or not if you look from the ground up.

In summer air movement helps rid the attic space of. A ridge vent runs across the top of the roof s peak. 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.

Roof vents help keep your home cool prevent moisture problems and generally encourage healthy airflow. A turbine has a series of vanes that spin as wind passes through them. A ridge vent as the name indicates is located at the ridges where your roof peaks and runs along the top of those ridges.
