A turbine vent is a passive ventilation device. The popular ridge and soffit ventilation systems and the traditional metal pot vents are also passive ventilation systems. A turbine vents spins with the slightest breeze. As soon as it starts to spin, it vacuums air out of your attic.
How does a roof ventilator work?
How Does Roof Ventilation Work? A roof ventilation system works by providing a continual flow of air through the attic space, helping remove overheated air and moisture from the attic and roof system and reduce the impact of changing temperatures and moisture conditions both inside and outside the home.17 ago 2015

Are roof turbine vents effective?

What is the most effective roof venting system?
Soffit Vents (Most Popular Intake Vent) It forms one half of the most popular combination of intake and exhaust; soffit vents (for intake) with a ridge vent (for exhaust). Soffit vents are a favorite amongst home builders and roofers because they are unquestionably the most effective intake vent for the cost.

How long does a turbine vent last?
A single 12-inch-diameter turbine vent can provide a complete change of air in the attic space every 52 minutes if the outside breeze is just 5 mph. A 14-inch diameter unit can provide a complete air change in the attic every 14 minutes if the wind is 15 mph.5 jun 2004
Are roof ventilators effective?
Does roof ventilation really work? Absolutely. Roof ventilation is an effective and efficient way to help regulate the temperature of your property, but only when done right.
How does a whirlybird roof vent work?

How does a gravity roof ventilator work?
A gravity ventilator consists of a fan built into a hole through a roof in a house. The fan helps draw the rising hot air up and out of the living spaces. ... Because a gravity vent operates mostly through the natural buoyancy of hot air, it requires little power to operate—much less than running an air conditioner.
What do turbine ventilators do?
The turbine vent It houses a circular fan that's very sensitive to breezes. When the wind blows the right way, it turns the fan, which in turn draws up air from the attic and disperses it.
