This occurs through the rising of warm air and the falling of cooler air.
Types of roof ventilation systems.
The two roof ventilation options intake vents and exhaust vents should be placed to take advantage of the natural increased speed of air circulation.
The downside to turbine vents is that they don t provide much venting power on calm days.
The box vent is also known as a static vent because it has no moving parts.
Instead the box vent is installed over a hole cut out of the roof.
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.
Intake vents such as soffits are placed lower on the roof usually under the eaves.
It uses the process of natural convection so that hot air and moisture can escape into the surrounding air.
They are meant to let the air from indoors travel outdoors so there is continuous air flow.
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.
Energy saving solar powered vents and skylights are also available.
Exhaust vents unlike intake vents are installed at the topmost point of the roof.
The most common type of moving roof vent is the wind turbine.
Solar powered vents gable mounted vents louvers rotating turbine roof vents and more.
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.
Turbine vents are not low profile but in windy climates they provide more ventilation than other types of roof 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.
Intake vents located at the lowest part of the roof under the eaves allow cool.
What type of ventilation system is right for you.
See the benefits of attic ventilation a new roof is more than just shingles.
Types of roof vents continuous individual soffits soffit vents are made of aluminum or vinyl and are one of the most popular intake vents.
Has provided a great online educational tool for understanding the difference between ridge vents power vents and static vents.
Other names for this type include low profile flat or turtle vent.
