Paneling that extends 36 to 42 inches or so upward from the floor level, over the finished wall surface. It is often finished with a horizontal strip of molding mounted at the proper height and protruding enough to prevent the top of a chair back from touching a wall surface.
Here's a link to Georgia Pacific, just one of the manufacturers out there!! http://www.gp.com/paneling/wainscot.html
Good luck. Again, I apologize for the sarcastic subject!
