Beadboard is a row of narrow wood planks lined up vertically (sometimes horizontally) on the wall. In between each wood plank is a little indentation or ridge—also known as a “bead”.
Standard beadboard comes in 1.5-inch and 3-inch widths. The size is determined by the width of the flat area between the beading. You can also have custom widths made. Beadboard is usually installed vertically, although some people install it horizontally for a different look. Beadboard provides a sturdy wall or ceiling surface and adds some insulation to a wall. Beadboard can be used for ceilings, walls and cabinetry. It can cover an entire wall or be used as wainscoting, which covers just the lower portion of the wall. Beadboard adds visual interest to any remotely blank wall. It is relatively durable, an inexpensive alternative to tile, can be painted any color, and installed at any height.
