Raised-panel doors have a solid-wood frame and a solid-wood center panel. Frame-and-panel doors consist of a solid-wood frame that surrounds a panel. The horizontal top and bottom pieces of the frame are called the rails, and the vertical side pieces are the stiles.
Raised-panel doors have a thicker center panel compare to flat panel door, so that the panel can fit into the narrow grooves of the door frame, the edges must be shaped down to reduce their thickness, and this molded profile gives the panel a distinctive raised look. With frame·and-panel doors, the panel fits into a groove milled into the rails and stiles.
