Re: Help with Attic Fans
Well to jump into the fray, turbine vents do work when they are not turning. You still have a 12" or 14" hole in the roof so it works like any other passive roof vent. When the wind blows they turn and are more efficient at removing the hot air just like an electric fan type.
If you are not getting proper ventilation of the attic it is most likely that added insulation or something else has covered the cool air intakes. Without the intakes you do not get proper air flow and the first turbine to turn draws air in through the other turbine. That would be called a short circuit and the drawn in air would be hot coming off the roof surface.
I think your best course of action would be to find and free up the intakes. The
cooler the attic the cooler the house because the heat from the house will rise toward the attic unless it is not properly vented.
