Disclosed is storm shutter apparatus for protecting building apertures such as door and window openings from hurricanes, wind-blown debris, gales, rain, and vandals using very low cost, low profile extrusion brackets designed specifically for installation during original building construction in combination with a variety of conventional manufactured windows, hinged doors or sliding glass doors in conventional building structures, and the use of those brackets with very low cost adjustable, lightweight isosceles trapezoidal corrugated panels. The first objective is to render building apertures compliant with the International Building Code (“I.B.C.”) even though they are constructed with conventional fenestration products unmodified for I.B.C. compliance. Another objective is to accomplish the foregoing without the expense of separate labor costs for the installation of hurricane shutters and without the expense of purchasing fenestration products modified for I.B.C. compliance.
