Abstract
Abstract A method of replacing damaged panels of a cladding system includes the use of a replacement panel. The replacement panel includes a sheet having a side hanger secured to a major surface of the sheet at each of opposed sides of the sheets and extending beyond their adjacent side of the sheet and a bottom hanger secured to the major surface of the sheet adjacent bottom edge of the sheet and having an exterior facing groove. After the damaged panel is removed, an opening is provided defined by the top hanger of the removed panel, vertical splines and a horizontal spline. The exterior groove of the bottom hanger is mounted on the horizontal spline and the panel tilted in position against adhesive provided on outer surface of top hanger. Extending portions of the side hangers are screw fastened to underlying ones of the vertical splines. Thereafter, the space between the previously installed panel and replacement panel is filled with a layer of silicone.
