High-End HardiPlank. The company that invented fiber-cement siding now has a premium line of this workhorse building material. Artisan Premier Lap Siding is thicker than the standard product and supposedly casts more dramatic shadow lines. Tongue-and-groove ends - rather than butt joints - enhance dimensional stability. The 5/8-inch-thick siding comes in 5 1/4-inch, 7 1/4-inch, and 8 1/4-inch widths and costs $2.50 per square foot. James Hardie Building Products, 888/800-7864, artisanluxury.com
