Most homeowners believe the purpose of attic ventilation is to remove heat that builds up in the summer. That’s accurate, of course…But what that answer leaves out is just as important as what it includes.
If you’ve ever walked into the stuffy confines of a room that’s been completely closed for a lengthy period, you know air tends to stay in place. You also know that just opening a door or window doesn’t solve the problem immediately. A flow of air must be established to produce the air exchange needed to remove all the stale air. That’s what an efficient ventilation system must do – provide a steady, high volume of air movement.
