PVC bead board is available in sheet sizes or individual pieces. We handle Versatex PVC Products. They have a wide variety of thicknesses for sheet goods, but if you want it for a wainscot look, like in the photo above, I would suggest the 1/2" thick material. It gives you the crisp shadow lines and depth of the bead. They also make a 1/4" and 3/8" thickness as well, but it will not give you as realistic a look as the 1/2" thickness. Other thicknesses up to 1-1/2" are also available. What application are you planning for this product? Let me know if you need pricing and availability. I would need to know quantities too. Thanks for the inquiry. Bob Myers
