Of the four door types all but the board-and-batten door are built using frame-and-panel techniques. The board-and-batten door is a solid panel door featuring a series of planks with rabbeted edges held together by battens screwed across the back of the door. Frame-and-panel doors feature a panel that floats within a frame composed of rails and stiles assembled with mortise-and-tenon or cope-and-stick joints. The floating panel in the center of the door can be raised or shaped for decorative effect. The rails and stiles have an integrated molding cut into them;for added embellishment you can also cut an arch or curve into the upper rail and panel.
Veneered-panel doors feature a panel made from veneered sheet stock that is glued to the frame. To conceal the plate joints between the panel and the frame, rabbets are cut into the inside edges of the frame at the back. Glass-panel doors are essentially a frame-and-panel door with a pane of glass replacing a floating panel. The piece of glass sits in rabbets cut along the edges of the frame. It is held in place by strips of molding. A variation of the glass panel door features glazing bars that hold smaller panes in place.Joined by mitered half-laps, the glazing bars have rabbets cut along their back edges to accommodate the glass and glass stop molding.
Although a door is always made to fit its cabinet, it does not always have to be sized exactly to fit its opening, as shown in the illustration on the opposite page. Flush-mounted and full-recess doors can be time-consuming to construct because of the fine tolerances required to fit and hang them properly. They are particularly unsuitable for board-and batten doors, as these doors tend to expand and contract with changes in humidity.
One of the most commonly used doors is the one typically used for European style cabinets-a piece of laminated particleboard such as melamine simply cut to size. While inexoensive and eisier to maintain, melamine doors need edge banding to conceal their non-laminated edses.
