A wind turbine consists of curved vanes configured in a circular shape. The vanes catch the wind, turning an internal turbine that pulls hot and humid air out of the attic. … When the thermostat senses a buildup of heat and humidity, it turns on the fan and blows out the stale air through the vent.
Are turbine vents effective?
Since turbines are attached directly to attic spaces, they can siphon away that moist air effectively. … They are incredibly effective at venting hot attic air, but there’s not always room for them.
How do turbine vents keep rain out?
During installation, turbine vents are sealed at several points to prevent water penetration. The base of the vent, where the flashing meets the stack, the nail heads, the bead joining the upper and lower sections, and the vertical seams in the stack are typically sealed with roofing cement or silicone caulk.
Are turbine vents better than box vents?
Wind turbine vents are able to move more air than box vents are, but only when the wind is blowing. The spinning action is triggered by wind, which in turn, draws hot air and moisture up out of the attic. Wind turbine vents are available in multiple degrees of quality, but we recommend higher quality wind turbines.
Where should turbine vents be placed?
Near the peak of the roof on a rear slope with the turbine top exposed to the wind from all directions. when installing two, place each one 1/4 the distance from each end of the house. when installing three, place one in the center and the other two 1/6 the distance from each end of the house.
Are turbine vents waterproof?
Turbine vents have been around for a long time and are designed to not let water in. Having said that, even flat vents can let some moisture in depending on blowing rainy conditions. You may also read, How do turtles catch their food?

What is the best type of roof vents?
Which type of vent is best for my roof? In most cases, we recommend soffit vents for intake and a ridge vent for exhaust. For homes that cannot have a ridge vent, box vents are generally the second best option for exhaust.
How many Turbine vents do I need?
How Many Vents Do I Need? The general rule of thumb in these situations is of roughly one vent per every 300 square feet of attic area if the attic has a vapor barrier. If not, there should be one vent for every 150 square feet. You will need to have 1 square foot of vent area for every 150 square feet of attic space. Read: How do turtles defend themselves?
Do turbine vents need to be level?
Should turbines be level? For optimal operation, the turbine should be installed level to the ground. The turbine can also fail prematurely if the wobble continues over the life of the turbine. The turbine head may have shifted slightly during transportation and minor adjustments may need to be made.
Do whirlybirds work without wind?
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.
Do whirlybirds make a difference?
The answer to the question “do whirlybirds work?” is yes. Whirlybirds work to remove hot air from roof voids, effectively ventilating the room or space below. … The roof of a building or house acts as a heat trap. Whirlybirds work to effectively remove the heat that builds up in rooms, by sucking out the hot air.
Do whirlybirds make your house colder in winter?
Whirlybirds remove damp air which means they reduce power bills in winter. Moisture laden air from inside the home, and outside air, can condense and cause dampness. Ceiling insulation loses its effectiveness when it becomes wet, and as a result, increases the need for heating to compensate for heat loss.
How do whirlybirds not leak?
By pulling that warmer, moist air out of the building, the whirlybird vents prevent the moisture from condensing into water. This means that not only do they not leak; they actively prevent water from forming inside the property.
