A combination ventilation baffle and insulation stop (referred to as "article") is described for use in building structures to provide air passage to the space between the roof and ceiling. The article may be further utilized to prevent insulation from clogging the passage or otherwise prevent free circulation of air therethrough. The article comprises a flat rectangular body having foldable side sections to facilitate mounting between roof rafters or joist members at a location adjacent the bearing plate of an outside wall. When installed, the apparatus defines an air passage between its central section and the structure roof. The passage may be selectively sealed through use of a pivotable tab during application of insulation then subsequently reopened thereby insuring proper ventilation.
