Abstract
A hinged vent chute, for providing ventilation to an open attic space, includes an elongated chute segment and an insulation dam segment. The elongated chute segment has one or more upwardly open channels, extending from a lower end to an upper end of the chute segment, that provide an air passage from a soffit region of a roof, over an interior surface of the roof, up into an open attic space beneath the roof. The hinged vent chute has a hinge or fold line joining the elongated chute segment to the insulation dam segment which permits the vent chute to be folded downward at the hinge to position the insulation dam segment for securement to form an insulation dam which prevents loose fill insulation in an attic from flowing down into a soffit region of a roof and blocking air flow. The insulation dam segment may also have one or more hinge or fold lines intermediate the ends of the insulation dam segment to permit the insulation dam segment to be folded intermediate its ends when positioning the insulation dam segment for securement to form the insulation dam.
