Lomanco® Intake Vent Product Line Galleries

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.

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.

The 105 Continuous Soffit Vent, SV-10 Starter Vent, and CV-4 Cirk-L-Vents are also available in copper.
