Abstract

An air deflector for installation with a roof ventilator having a pair of vent parts defining a multiplicity of air passages, the air deflector comprising a base member and a generally upright air flow blocking member extending upwardly from the base member at a generally acute angle of 75.degree.. Two air deflectors extend along the entire length of the roof ventilator proximate to the outer edge of each opposing vent part. The base member is disposed between the bottom surface of the corresponding vent part, and the upright air flow blocking member confronts and is spaced apart a selected distance from the outer edge of the vent part and angles inwardly slightly toward the vent part. The top edge of the upright air flow blocking member angles slightly outward away from the vent part, and is disposed at approximately the same height as the top panel of the roof ventilator. The base member includes end notches designed and positioned to facilitate installation and retrofitting of the air deflector with a wide variety of existing roof ventilator configurations, and spacing of the upright air flow blocking member at desired distances from the outer edge of the vent part.
