How Attic Ventilation Works
Intake and Exhaust
"Ventilate" comes from the Latin word for "to fan." Simply put, it's the action of moving air. Out with the hot. In with the cool. And that's exactly how ventilation works. It provides conditions that allow air to flow. Every time stale, overheated air in your home or attic is vented out and fresh air is pulled in to replace it, you have what is known as an "air exchange."
But ventilation is much more than a simple breeze blowing through your house. It's a process that provides a steady, high volume of air movement. Think about it as a system of components, all sized and positioned to provide constant intake and exhaust of air.

Smoke Bomb Demo
This segment highlights how well a ridge vent designed with an external baffle uses the wind to its advantage to pull more air out of the attic in testing conducted at the University of Florida. See the Bernoulli Effect for yourself!
