Louvers are the vertical openings in the vent, which facilitates the flow of air, while keeping animals, insects, debris, and embers out.  The combination of inner and outer Louvers on our signature “Aura” series of vents and fans are shaped to create a positive vacuum effect which draws air out of the vent, utilizing a physical principle known as the Venturi effect.

How much clearance (vent height) your roof vent needs depends on the pitch of your roof and the climate zone you live in. If you have a 4/12 roof pitch or greater, you can have a low profile vent (1” 2” tall collar) in all climate zones. At a 3/12 roof pitch you can have a 1” or 2” tall collar in zones 1, 2, 3. Having a 3/12 roof pitch in zones 4, 5, 6, 7, 8 you will need a 4” tall collar. For roof pitches 2/12 or less you will need a 4” tall collar in zones 1 & 2. You will need a 6 inch tall collar for zones 3, 4 and an 8” tall collar for zones 5 and 6. You will need an 11″ or 12” tall collar for zones 7 and 8. Bear in mind, you can always use taller collars for additional clearance in warmer zones, but you can’t use shorter collars in colder zones when dealing with low slope roofs. Custom collar heights are also available.

The Venturi effect stimulated by even small breezes creates a positive movement of air out of the vent without the need of any part of the vent to move. This movement of air is proportional to the wind speed, and can be measured in Cubic Feet per Minute or Cubic Meters per Minute.
