Abstract:

A baffle vent is provided for positioning against the underside of a roof to direct air from the soffit area of the roof upwardly over the interior surface of the roof. The baffle vent is an elongated self-supporting unitary structure of sheet-like material having a generally channel-shaped cross-section defining longitudinal side walls joined by a bottom wall. Attachment flanges project from the top edges of the side walls for facilitating attaching the baffle vent to the underside of the roof. An integral longitudinal reinforcing rib is provided in the bottom wall, running along a substantial length of the baffle vent, generally parallel to the side walls, to resist collapsing of the baffle vent if subjected to external forces such as from roof insulation, handling, shipping and the like. A structure is contemplated with a plurality of the reinforcing ribs spaced in an in-line orientation longitudinally of the bottom wall, whereby the structure can be cut to length between adjacent ends of a pair of spaced in-line ribs.
