What is ventilation?
Last Updated 4 years ago
Ventilation is simply the process of supplying a continuous supply of air through the attic space. "Proper Ventilation" consists of 50% intake ventilation, near the lower part of the attic space, and 50% exhaust ventilation, near or at the roof peak, at least 3 feet higher than the intake system.
Simply put, ventilation = Good Air In, Bad Air Out. Intake vents allow fresh air in and exhaust vents let heat and moisture out of the attic.
The Ventilation Guide provides additional information on ventilation and the different types of products available.
