They are incredibly effective at venting hot attic air, but there’s not always room for them. When an attic space needs ventilation but there’s no more room for ridge vents, turbine vents are usually the next best solution. They are very flexible regarding placement, and there’s almost always room for them.
What do turbine ventilators do?
A non-electric alternative to ventilation, these vents use the natural force of wind and air pressure to spin and vent out stale attic air. They do it with a series of specially shaped vanes that catch the wind and provide rotary motion. This pulls hot, humid air from the attic.
How much do roof turbine vents cost?
