Westlake Royal Building Products has added an 11-inch board-and-batten profile to its Celect Cellular Composite Siding line. The manufacturer says the low-maintenance vertical profile is easy to install and has an interlocking seam design that keeps moisture out. With the aesthetic of wood and available in 15 fade-resistant colors and in ready-to-paint Celect Canvas, the siding is treated with Kynar Aquatec coating for protection against UV, dirt, insects, and seasonal staining. westlakeroyalbuildingproducts.com
