Intake Vents
Don’t Forget The Intake!
The KEY to balanced ventilation is proper intake.
Inadequate intake is the #1 cause of attic ventilation system failure. Specifically, inadequate intake results in extreme heat buildup in the summer and severe weather infiltration and moisture problems in the winter.
The intake system must provide as much as or more than the exhaust system in Net Free Area.
Intake Options
Proper vent chutes should be installed before blown-in insulation to prevent choking your intake system. A good rule of thumb is to place one between each set of rafter tails in order to maximize intake air.
If maintenance free vinyl/metal under eave panels are used, the vented panels should be installed continuously around the under eave portion of the house.
If the under eave width prohibits the use of cornice or strip vents— never use an exhaust louver as an intake vent. The most logical solution would be to install SV-10 Starter Vent or the Deck-Air™ Roof Deck Installed Intake Vent.
The 105 Continuous Soffit Vent, SV-10 Starter Vent, and CV-4 Cirk-L-Vents are also available in copper.
