Abstract

See full text

A method of injection molding a building product includes providing an injection mold with a plurality of gates located adjacent a perimeter of the injection mold. The method further includes commingling a first material and a second material into a flow, the second material comprising a color that contrasts with a color of the first material and injecting the commingled flow into the plurality of gates to form a building product. Thereafter, the method includes removing the building product from the injection mold. The second material extends through an interior of the building product and appears as contrasting streaks on an exterior of the building product to form a variegated grain appearance. The method also includes notching a portion of the building product, such that the building product has a substantially linear grain in an exposed portion thereof.
