Somebody told me well you ll save money in the winter if you cover your turbines up tom.
Attic turbines are an important component of attic ventilation.
These all work well and are typically installed near the top or the peak of the roof called the ridge.
The answer is yes they really do.
Most residential homes have some type of attic ventilation.
They also create zones of negative pressure that could pull the ac cooled air into the attic.
Well now you know.
Unlike turbines this venting style does not have any moving parts.
It could be dormers gable end vents ridge vents turtle vents or turbines vents.
Attic turbines should spin as heat rises.
One static vent style is the turbine vent which uses wind to power its enclosed fan all it takes is a light breeze to rotate the blades and suck heat out of the attic view example on the home.
In fact the same vents are still in place on the home and each time the slightest breeze blows they do a great job of pulling air from the attic space.
To get the best performance these vents should be within three feet from the ridge.
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.

Wind driven roof vents will pull more air from the attic but only when the wind is blowing.
Solar power is safer to use with an attic fan.
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.
The safety and effectiveness of an attic fan is a subject that is hotly debated but line powered products usually cost more to operate than they can produce in savings during the summer.
A turbine vent is a passive ventilation device.
Improperly ventilated attics can have issues with mold and mildew as well as ice buildup and leaks in winter and can increase home cooling costs in summer.
The popular ridge and soffit ventilation systems and the traditional metal pot vents are also passive ventilation systems.
A ridge vent runs across the top of the roof s peak.
A turbine has a series of vanes that spin as wind passes through them.
