For improved air circulation in the attic install the durovent 22 in. Baffles are also called wind baffles venting chutes rafter vents or insulation baffles. That airflow is intended to churn the stale air in. Basic functions of baffles baffles are chutes that when installed properly can provide a channel for air to flow from your exterior soffit vents up into your attic space.

Use it between rafters to create an air channel through insulation to help keep air flowing freely in your attic. Air seal the attic baffle once the attic baffle is fixed in place seal the drywall edge against the interior wall with a bead of foam sealant then fit one of the foam blocks horizontally over it. Baffles provide a channel for air to flow through certain parts of the attic. The picture below courtesy of the epa indoor airplus program which we provide builder verification services for helps show how the system works.

The foam block should sit flush over the exterior sheathing on the outside and the interior drywall on the inside. Surprisingly even the most well insulated attic space may still require the assistance of attic baffles to provide the additional air circulation.
