Common Belief: Attic ventilation is not needed when a proper vapor retarder is used on the attic floor.*

Truth: Even with a good vapor retarder, proper ventilation is essential to prevent damaging condensation. Eave vent openings at the roof overhang combined with a ridge vent, roof vent, or gable vents, are effective ways to create a positive movement of air in and out of the attic.

*Note: Check your local building codes on ventilation and moisture control requirements in your area.
