The Ultra Seam Flush Panel system is ideal for gable walls and soffits where a smooth flat surface is desired. Horizontal flanges of 1-1/8" or 1-1/2” seams interlock and provide attachment surfaces for concealed fasteners. The panel seam combined with attachment flanges strengthens the panel to provide good spanning capacity. Fewer supporting structural members needed for high gables and wider soffits means lower installation cost. Available in twelve inch and sixteen inch widths.
