CONTINUOUS SOFFIT VENT

INSTALLATION INSTRUCTIONS

Continuous Soffit Vent can be combined with all types of

high ventilators for a balanced ventilation system. It installs

in the soffit as close as practical to the facia and offers

these advantages:

• Continuous Soffit Vent provides a continuous vent

opening for uniform distribution of intake air across the

underside of the roof sheathing.

• Continuous Soffit Vent keeps infiltrating snow and

rain away from ceiling insulation with a special louver

pattern. Intake air from half of the louvers is directed

toward the flow of air from the other half, creating a

gentle turbulence that permits snow and rain to fall out

of the air stream onto the vent or adjacent soffit, rather

than being carried to the insulation. 1/8˝ louver

openings prevent entrance of flies, bees, wasps and

other insects – yet are large enough to avoid being

clogged by dust and dirt.

• Continuous Soffit Vent installs easily on almost all

types of construction.

The most effective airflow through the attic space is provided by

low intake venting located along the soffit, combined with high

venting for exhaust. Research and experience have shown that

ridge vents are the ideal high venting, providing a uniform flow of

air along the underside of the roof sheathing and along the entire

ridge to help prevent summertime heat buildup and wintertime

moisture condensation. However, regardless of the type of high

vents used, a continuous soffit vent along the outer edge of the

eave provides proper air intake.
