Brad Diepholz found the following information.

 

In planning the location of intake and exhaust vents two other factors must be considered.

 

  1. Intake and exhaust vents must be positioned so they assure continuous airflow along the underside of the roof sheating. As I spoke about in the introduction this is where ventilation is most effective. During the summer months airflow along the sheathing removes heat before it can radiate to the attic floor. During the winter months airflow along the sheathing removes moisture before it can condense into water droplets or frost.
  2. Intake vents must be located so there is little possibility of rain or snow infiltration. Conventional intake products require installation in the soffit of maximum weather protection.

 

Types of vents-

In describing how ventilation works we discussed intake and exhaust vents in general terms. Perhaps giving the impression that a single type existed to serve each function.

 

However you can choose from a wide range of intake and exhaust components allowing you to tailor ventilation systems to the specific characteristics of every home.

 

In general ventilation components can be divided into two broad categories. The intake vents and the exhaust vents. Within each category there are various styles. Ventilation components are either fixed or powered.

 

Fixed ventilation components are exactly that. The units that don’t require moving parts or power assistance for proper functioning. But do not let that description lead you to believe fixed ventilation is a low-tech alternative to high efficiency systems.

Just the opposite is true. Fixed ventilation components form the core of all attic ventilation systems from the simplest to the most sophisticated. In most cases your initial goal should be to try to design a ventilation system that uses only fixed vents or ridge vents.

 

A ridge vent is a special high-efficiency type of fixed ventilation. Since fixed ventilation can be used to create an entire system units are available for both intake and exhaust functions.
