A plastic siding panel which includes an upper connector, a medial main portion, and a lower connector. The connectors are complementary in shape so that they interlock with other siding panels of like construction. At least one of the connectors include a strip of high strength material for rigidifying the siding panel. The siding panels are fabricated by extruding a monolithic, substantially planar sheet composed of three different materials. Two of the materials are formed as layers which extend over the entire sheet. The third material is a high strength material adapted to rigidify the siding panel. After extrusion, the sheet is formed into a siding panel having a main portion, an upper connection and a lower connection.
