Where metal or vinyl siding has been applied, window trim has been covered. Storm windows are of wood or aluminum. Required Original windows and doors shall be retained including sashes, lintels, sills, shutters, decorative glass, pediments, hoods, and hardware. When deteriorated beyond repair, they shall be replaced with units and trim resembling the original. Recommended Wood frame storm win- dows and doors painted to match the original should be used but should not damage existing frames. If new sashes or doors are installed, the existing or original materials, design, and hardware should be used. When metal storm doors are used, they should be painted, anodized or coated to match the exist- ing. When awnings are used they should be of can- vas material. Figure S.
