Abstract
A method of molding a building product may include providing an injection mold with a plurality of gates located adjacent a perimeter of the injection mold. The method may further include commingling a first material and a second material into a flow. The second material may be a color that contrasts with a color of the first material. The method may include injecting the commingled flow into the plurality of gates to form an injection molded building product, and removing the molded building product from the injection mold. In addition, the second material may extend through an interior of the molded building product and appear as contrasting streaks on an exterior of the building product to form a variegated grain appearance.
