Abstract: A ducted frieze vent which creates a duct-way for the free flow of air beneath the roof sheathing and between a pair of roof rafters and into the space beneath the building's roof. The frieze board employed has a sufficient thickness to accept a nail driven down through the roof sheathing as is required by many building codes. The duct-way is provided with a removable closure which is first positioned to prevent entry of airborne insulation into the duct-way. After insulation has been emplaced, the duct-way closure is removed by manual actuation of a rod by a person exterior of the building and of the insulated space.
