Abstract: An injection molded product is disclosed and includes a shingle resembling a cedar shingle tile formed from an amorphous or semi-crystalline thermoplastic and having a wood grain direction. The injection molded product also includes streaks in the shingle that are substantially parallel to the wood grain direction and the streaks extend through an interior of the shingle and appear as contrasting streaks on an exterior of the shingle to form a variegated wood grain appearance. The injection molded product further includes an injection molded vestige in the shingle. The injection molded vestige is located adjacent to a perimeter of the shingle and the injection molded vestige comprises a location at which material entered an injection mold through a gate.

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.

Abstract: A dark-colored siding panel product includes a shell having a layered structure. The layered structure can include a substrate comprising polyvinylchloride. The substrate may be located between inner and outer layers. The inner and outer layers may be formed from a weatherable polymer. In addition, at least the outer layer may have a CIE color unit L*<75. An insulation layer may be mounted to the shell.
