Cinderstone merges the edgy look of split-faced block with the endurance and economy of fiber cement. Available in canyon brown or field gray, the 18-inch-high-by-6-foot-long panels are ship-lapped on all four sides for a seamless fit. Multilayered coating creates an authentic finish that the maker says will survive extreme weather and resist fungus and termites. The company says its panels won't crack or rot and are backed by a 50-year transferable warranty. Nichiha, 86.NICHIHA.1;
