A frieze board is a decorative band located on an outside wall or at the top of an interior wall. The frieze board can include lettering, sculpture or other decorations. Frieze boards can also be found underneath the cornice, an interior wall or a piece of furniture such as a table.
A frieze board does not only provide decoration but can also provide function to the wall. It can help prevent air flow from entering the attic as well as keep insects and other small animals from entering and building nests. Aesthetically, the frieze board can help make a house's overhang look taller when viewed from the street.
