Proper Attic Venting spray foam insulation help prevent heat and moisture from leaking into a home, resulting in energy savings, reduced maintenance costs and healthier indoor air quality. The ventilation system should include both intake and exhaust vents to create a cyclical airflow through the attic. Intake vents (soffit and gable) are critical to drawing in fresh air, while exhaust vents (ridge or power fans) ensure that hot and moist attic air can escape.

Attic baffles, also called rafter vents or insulation baffles, are another option to enhance attic ventilation. Installed between the rafters, they prevent insulation from blocking soffit vents and allow air to flow freely from soffit vents into the attic.

Attic Energy Savings Checklist

While the rectangular slotted gable vent was once the standard attic ventilation method, it’s not as effective as modern methods. Modern ridge vents, for example, are one of the most effective ways to properly ventilate an attic. They’re also more attractive, and they can blend into the roofline, making them a great choice for homes that don’t have soffit vents.

Pros – Ridge vents are a simple and effective way to improve attic ventilation, as they take advantage of the natural principle that warm air rises. These vents can be fitted to soffit and eave areas, and they work well in conjunction with other attic vents for maximum effectiveness.

Cons – Ridge vents require periodic cleaning to maintain their efficiency. Debris, nests and even paint can clog the vents, which reduces their efficiency. Additionally, the cost of running a power vent can add up over time, especially in warmer climates.
