Abstract: A colonial storm shutter assembly with improved impact resistance includes shutter blade elements having a corrugated configuration that exhibits superior structural strength and bending resistance while providing an attractive face. Triple, double and single shutter blade elements overlap to provide enhanced structural strength and simplify assembly. Side frame structures include a reinforcing portion on the outside wall which provides increased strength particularly in the miter joint with top and bottom frame structures. A storm bar includes a center storm bar clip which bolts to the side frames of two shutter panels when in the closed configuration to provide enhanced structural rigidity. Center fastening angles are bolted to the side and top/bottom frames at both the top and bottom where the two shutter panels meet in the closed configuration to provide further structural strength and resistance to opening.

Abstract: A Bahama-style storm shutter design with improved impact resistance includes shutter blades which span the width of the shutter, supported at each end by an end cap locked within side rails and supported in the middle by a center mullion having slots machined to approximately matching the blade cross section. The storm shutter design eliminates the need for extra structure to attach shutter blades to the side rails, thereby eliminating cost and fabrication complexity. The pass-through center mullion provides structural support to the shutter blades, enabling the use of full width shutter blades and eliminating center blade attachment structure.
