How well do roof turbines work?
While a turbine looks a little complex at first glance, it’s actually very simple. Much like a window, this round vent is powered by the wind. 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.
How many roof turbines do I need?
A general guideline is homeowners need one square foot of roof vent for every 300 square feet of ceiling space, if your home has a roof with a vapor barrier, or 1:300. If not, you should have one square foot of roof vent for every 150 square feet, or 1:150.
Are roof turbines necessary?
Why do you need roof turbines? During winter months, warm air rises into your attic. Without proper ventilation, the extra moisture in the heated air will cause wood rot, mildew, mold and exterior problems like ice dams. Roof turbines remove attic moisture and reduce the risk of costly roof damage.
Should I cover my roof turbines in the winter?
You should absolutely leave your roof vents open during the winter – do not cover them! During the winter, roof ventilation works to keep temperatures even. Closing your vents makes the attic space too warm and dry – dangerous conditions for mold as well as pests.
Do whirlybird roof vents work?
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.
What is the purpose of a roof Turbine?
Roof turbines utilize the free power of the wind to boost attic air circulation. This reduces attic heat infiltration through the ceiling into living spaces and lowers utility costs. Roof turbines also exhaust humidity that condenses in the attic, damaging insulation and promoting mold.
Do turbine roof ventilators work?
Even though roof turbines do not consume any energy they remove air just like active ventilators. This is because when the wind flows, it moves the fins of the turbine vent making it work as an active ventilator. But roof ridges work based on the principle of convection of heat.
Do you need to cover roof turbines in winter?
Winter Ventilation. There are many types of vents that you may have on your roof, including turbine, soffit, rafter and metal pot vents, but you should not cover any of these roof vents during the winter. All of these vents serve the purpose of creating air circulation, which is vital to keep your attic and roof from being damaged in the winter.
How does a wind turbine roof vent work?
The concept behind wind turbine vents is that the turning blades will help force air out of the attic. Hot air naturally rises, so if attic air is heated above the ambient air temperature a vent will allow the less dense hot air to escape.
