From wood to PVC, siding categories flaunt new offerings, expanded product lines, and improvements over past products. Here is a selection.

CLAD TIDINGS: Clockwise from left, Owens Corning's ProStone stone veneer siding has many combinations of color and texture; Microposite's siding promises shadow lines and no-repeat grain patterns; Shakertown's cedar shingle panels have grooves that channel moisture away from the wall. Specially placed grooves in Shakertown's Craftsman one-course cedar shingle panels let water flow both horizontally and vertically, channeling moisture away from the wall and down to the ground, the maker says. The Western red cedar shingles feature concealed nailing and self-leveling design. They come 8 feet long and natural, primed, or pre-finished with a semitransparent oil stain in one of four colors. 800.426.8970. www.shakertown.com.
