XO Cellular PVC Board is the high-quality wood replacement remedy offering rot-free solutions without giving up the look of wood. The superior exterior solution, XO can be used for trimboards, fascia, cornerboards, beadboards, columns and more, but must never be used in load bearing applications.

XO Cellular PVC Board is available in XO Smooth or XO Wood Grain (one side features the look of natural wood grain and the other side is pre-sanded to a smooth finish). When using XO Wood Grain, pay close attention and be consistent, turning the same side out throughout the job. If you know that your project will require smooth surfaces only, then simply order XO Smooth.
