ABSTRACT:
A pleated ridge cap ventilator constructed from a single, generally square sheet of double-faced corrugated polyethylene sheet material which is cut and scored into a series of interconnected longitudinal panels. Each score line alternately cuts entirely through one of the two opposing planar plies of the blank and through the intermediate corrugated ply, leaving the remaining planar ply intact to hingedly connect the adjoining panels. The widths of the panels form a generally increasing progression from the outer edge panels inwardly to the center panels. The center panels are connected by removing a wider section of one planar ply and the intermediate corrugated ply, leaving the opposing planar ply to act as a bridge. The blank is then accordion folded along the score lines to form two inverted pyramid-shaped ventilating sections joined at the top by the bridge, which are bent downwardly relative to one another into an inverted V-shape of approximately the same angle as the slope of the roof. The ridge cap ventilator is then disposed over an open cutout in the peak of the roof, covered with shingles, and attached to the roof using nails or similar fasteners.
