Abstract: An endpiece and method for siding a wall to simulate wood log construction are described. A generally cylindrical core (101) of the endpiece (100) has a curved surface (103), and a flat surface (105). A decorative skin (111) attached to the curved surface (103) has a cross-sectional arc that is greater than one hundred and eighty degrees. When an endpiece (100) is installed on a plank (200), a spline (117) that attaches along a lateral edge (109) of the endpiece interlocks with a bottom spline (215) of a plank (200). Also, a first offset (113) of the decorative skin (111) engages an upper lateral edge (207) of the plank (200). An end cap (301) attaches to a surface formed by an endpiece surface (305) and a plank surface (307).

Abstract: A column and method for siding a wall to simulate wood log construction are described. The column (100) includes a partial cylinder core (101) having a channel (103) that complements the shape of the wall to which the column attaches. Lateral supports (117, 119) are attached to respective grooves (113, 115) along respective lateral edges (109, 111) that are formed at the intersection of the flat surfaces (105, 107) of the channel (103) and a curved surface (123). A decorative skin (121) attaches to the curved surface (123). In a siding system that simulates wood log construction, planks (200) are attached to wall adjacent to a column (100).
