MUST
DO
Steps
to attic ventilation
Install all Exhaust Ventilation at the SAME HEIGHT with-
in a common attic area.
Installation of exhaust vents at more than one level on a roof allows
the upper exhaust vent to pull air in from lower exhaust vents rather
than from the intake vents. Intake air must come from intake vents
located near the lower part of the attic space to properly ventilate
the total attic area and eliminate weather infiltration.
Install ONLY ONE TYPE of Exhaust Ventilation within a
common attic area.
Exhaust Vents pull air from the easiest intake source. Vent types
cannot be mixed. The use of different types of exhaust vents could
make one of the vents act as intake for the other. Intake air must
come from intake vents located near the lower part of the attic
space to properly ventilate the total attic area and eliminate
weather infiltration.
Install a BALANCED SYSTEM of Intake and Exhaust
Ventilation.
50% Intake Ventilation - Intake vents located near the lower part
of the attic area are required to balance out your ventilation system.
50% Exhaust Ventilation - Use a Lomanco Ventilation Selector
Guide, or the calculators at lomanco.com to determine the number
of vents needed to properly ventilate an attic to meet the Ventilation
Minimum Property Standard.
