DuraPlank Vinyl Sidingby Royal Building Products

Royal's DuraPlank is vinyl siding with a difference -- a foam-reinforcement layer. This gives the siding an R-value of 3.46; a flatter, more traditional look; and greater impact resistance. The resilient foam backing is closed cell for waterproofness, corrugated for drainage and airflow, and loosely attached to allow expansion and contraction. The siding is 12 feet 3 inches long with a 7-inch exposure and comes in twelve colors. A 100-square-foot pack costs $160. 800/387-2789, royalbuildingproducts.com
