A great alternative to real wood — natural white and ready to install, or paint to match any colour
Restoration Millwork® PVC Trim Boards
Restoration Millwork® PVC Trim Boards by CertainTeed are the professional's choice for low-maintenance exterior trim in Canada. Made from cellular PVC with FinishedEdge™ heat-sealed edges and TrueTexture™ woodgrain finish, these boards eliminate the ongoing maintenance cycle of painted wood — they will not rot, warp, or absorb moisture. Available in 3/4" (1×) and 1" (5/4) thicknesses across widths from 4" to 16", with lengths up to 18 feet, plus specialty J-Pocket Trim and Skirt Board profiles. Ideal for soffit, fascia, rakes, frieze, bandboards, column enclosures, corners, and window and door surrounds. Ships natural white and is fully paintable. Meets ICC and CCMC code requirements, carries a Class A Flame Spread rating, and is backed by a 25-year limited warranty.
