A panel for polypropylene injection molded siding, and for similar materials and/or uses, is mounted in lapped courses with panels attached at butt joints in a direction of elongation. Complementary tabs and slots at the panel ends can be engaged by end-to-end approach of the abutting panels. Additionally, openings for the tabs permit engagement from a position in which the panel ends are already overlapped, which reduces or eliminates the need for endwise assembly space. The slots can be discontinuous on one or both sides, openings permitting lateral insertion of the tabs at gaps, whereupon movement of the tabs along the slots engages the joint. The panels can simulate wood siding and include a step between simulated courses. A gap is provided in the edge of the panel at the step, thus forming an opening for the tab to enter and move along the slot.
