Abstract: A hinged roof vent panel is provided which includes a combination of hinged ridges that allow the panel to be cut and folded to form an insulation block which inhibits the flow of loosefill insulation which may block soffit vents and which provides suitable ventilation to inhibit condensation during cold periods and to allow acceptable airflow during warm periods. The vent panel is typically thermoformed from a thin sheet of extruded polystyrene foam into the shape described and claimed. The panel is relatively planar and stackable so that a large number of panels may be packaged together for shipping.
