Hinged roof vent for attic

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.

Description

TECHNICAL FIELD AND INDUSTRIAL APPLICABILITY OF THE INVENTION [0001] This invention relates generally to a panel for use as a roof vent, and more particularly, to a hinged vent panel for use on a sloping roof to allow for attic ventilation and to inhibit the flow of insulation out of an attic area into the soffit of a structure to block a soffit attic vent. BACKGROUND OF THE INVENTION [0002] Homes and commercial buildings with sloped or pitched roofs typically include an open, unheated attic. The area of the attic is typically insulated by a layer of fibrous insulation, for example, loosefill fiberglass, batts or rolls of fiberglass insulation, or other insulation materials such as cellulose, mineral wool. Building codes often require that an unheated attic be vented to release heat and moisture that may otherwise build up. Often the vents are positioned in the soffit at the eaves of the house to allow airflow from the soffit vents to the peak vents. Due to the position of the soffi...
