Patent ID: 7856764

Claim:
A vent baffle assembly for a cathedral ceiling to provide air ventilation in a cathedral ceiling portion of a building structure from a soffit area along roof sheathing affixed to rafter beams to an elevated vent, the vent baffle assembly comprising: a first vent sheet having a first longitudinal axis and a first lateral axis perpendicular to said first longitudinal axis, and including a first longitudinal rib extending parallel to said first longitudinal axis and a first lateral stiffener extending parallel to said first lateral axis; and a second vent sheet having a second longitudinal axis and a second lateral axis perpendicular to said second longitudinal axis, and including a second longitudinal rib extending parallel to said second longitudinal axis and a second lateral stiffener extending parallel to said second lateral axis, the first and second vent sheets being positioned between two adjacent rafter beams such that the first and second longitudinal axes are generally parallel to the rafter beams, the first and second vent sheets overlapping such that the first longitudinal rib engages the second longitudinal rib to limit lateral movement between said first and second vent sheets, with the first lateral stiffener engaging the second lateral stiffener to limit longitudinal movement between said first and second vent sheets.
