Designed specifically for Cathedral Ceiling designs, works equally well in traditional applications. Baffle allows airflow and prevents insulation from blocking airflow. These are Extension Pieces, which work with Accuvent baffles for each rafter opening. These “extensions” extend the ventilation path up to the ridge vent. A favorite choice of “spray foam” insulation applicators. 100% recycled flame retardant plastic meets the new EnergyStar Thermal Bypass Checklist requirement.
