Ventilation Requirements

In order to create a consistent flow of cool, dry air through your attic, you need to make sure the air has a way to come in and go out: intake and exhaust. It’s important there is a balance between the intake and exhaust ventilation to help ensure air flows smoothly and efficiently.
