If you ever need to add insulation to the attic of your home, it’s important to keep it from obstructing the vents. As strange as it sounds, you want air, whether it is cold winter air or hot summer air, to flow through your attic. That’s why you have soffit and roof vents. This airflow helps equalize the inside and outside temperatures of your roof to prevent condensation, mildew, and other problems.
Of course, you don’t want that air to get into the living spaces of your house, which is why you need insulation.
When you add insulation, you need to make sure that the area around the soffit vents isn’t obstructed. The easiest way to do that is to install airflow baffles (Illustration). The baffles provide space for air to flow under the roof but over the insulation. You can find the baffles in home centers.
To ensure that insulation won’t block airflow through your attic, install airflow baffles. Usually made from polystyrene foam, these simple chutes get stapled in place between the roof rafters to provide unobstructed airflow.
