On a windy day the vent s turbine mechanism spins which moves hot attic air up and out.
Types of roof ventilation systems.
Moving vents have the benefits of actively removing hot air and moisture from your roof but you will have to rely on wind power to operate these roof vents.
The downside to turbine vents is that they don t provide much venting power on calm days.
Instead the box vent is installed over a hole cut out of the roof.
Intake vents such as soffits are placed lower on the roof usually under the eaves.
What type of ventilation system is right for you.
They are meant to let the air from indoors travel outdoors so there is continuous air flow.
Effective attic ventilation systems reduce damaging heat and moisture in your attic promote energy efficiency by helping to reduce the load on your air conditioner in the summer and also reduce the risk of ice dam formation on your roof.
Exhaust vents unlike intake vents are installed at the topmost point of the roof.
Ridge ventilation is suitable for peaked roof systems.
Other names for this type include low profile flat or turtle vent.
Solar powered vents gable mounted vents louvers rotating turbine roof vents and more.
It uses the process of natural convection so that hot air and moisture can escape into the surrounding air.
The box vent is also known as a static vent because it has no moving parts.
These vents are available in various types and styles and soffits are easy to install under the roof s overhang which is known as the soffit.
Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents.
Comprised of intake and exhaust vents the basic roof ventilation system can be found in a few forms including turbine vents low profile vents and ridge vents that are specially designed to accommodate specific roof shapes.
The trapped hot air goes out from the attics through the ventilation space into nature.
This occurs through the rising of warm air and the falling of cooler air.
The two roof ventilation options intake vents and exhaust vents should be placed to take advantage of the natural increased speed of air circulation.
Has provided a great online educational tool for understanding the difference between ridge vents power vents and static vents.
Intake vents located at the lowest part of the roof under the eaves allow cool.
Energy saving solar powered vents and skylights are also available.
Types of roof vents continuous individual soffits soffit vents are made of aluminum or vinyl and are one of the most popular intake vents.
