What Is A Baffle?
Just what is a baffle? A baffle is a small piece of cardboard or plastic that fits between the insulation and the sheathing and creates a small gap. This gap allows air to flow freely and keeps the insulation from covering the soffit vents. Without the ventilation provided by the baffles, air can become blocked in the attic. Baffles work much like windows — when there’s just one, not much changes. However, when you have multiple baffles you’ll get a cross breeze which allows hot air to escape.
Why They’re Important
An attic that’s not properly ventilated can lead to a number of problems. First and most importantly, ventilation keeps the air toward the roof as close to the outside temperature as possible in the winter. This helps prevent ice damming, which occurs when the roof warms up and causes the ice to melt. Without a baffle, the water can become stuck behind a section of ice, causing a pool of stagnant water. This water has no where to go, which means that it will eventually seep through the shingles and cause damage to the home’s interior.
