The Balance of Intake and Exhaust
Ventilation works on a balance, and a Glenns Valley homeowner benefits from understanding it. Here is the picture.
Intake Brings Air In
Intake vents, usually low on the roof at the eaves, bring cooler air into the attic. Intake brings air in. It is low on the roof. It is at the eaves. It brings cool air. It starts the flow.
Exhaust Lets Air Out
Exhaust vents, usually high on the roof near the peak, let warm, moist air out. Exhaust lets air out. It is high on the roof. It is near the peak. It releases warm air. It completes the flow.
Balance Keeps Air Moving
A balance of enough intake and exhaust keeps air moving through the attic, which is what makes ventilation work. Balance keeps air moving. Enough intake matters. Enough exhaust matters. They pair. It makes it work.
Imbalance Reduces Effectiveness
An imbalance, like too little intake, reduces how well ventilation works, so the balance matters. Imbalance reduces effectiveness. Too little intake hurts. Too little exhaust hurts. Balance is key. It is worth getting right.
Intake and Exhaust, in Short
Ventilation works on a balance of intake vents low at the eaves that bring cooler air in and exhaust vents high near the peak that let warm, moist air out, with enough of both keeping air moving through the attic, while an imbalance like too little intake reduces how well ventilation works.
