Made from cellular PVC, CertainTeed Fiber Cement Skirtboard is the ideal solution for meeting U.S. building codes requiring 6" ground clearance. When used as a transition panel between siding styles, Fiber Cement Skirtboard offers added ease of installation, performance and style. It also features our Patent Pending DualStart Design - smooth finish on one side; TrueTexture wood grain on the other. While CertainTeed cellular PVC looks and feels like top-grade lumber, it provides performance and aesthetic advantages that wood and other materials just can't match, with no worries about rotting, warping, moisture or insects. It is suitable for residential and light commercial applications. Our trimboards come with FinishedEdge®. The product edges are heat sealed using a proprietary CertainTeed process that creates a smooth finish, preventing dirt from collecting on the surface. This "smooth edge" feature is also available on all corners. Restoration Millwork comes in Natural White and does not require painting for protection.
