Pediments are the portion of the trim that is located above the pilasters, which are the column like frames on the sides of windows and doors. Directly below the pediments though, between the pediment and the pilasters, is a crosshead or breast board. The crosshead is the flatter, protruding section directly above the door. Pediments can be purchased by themselves or can come with a crosshead already attached. These Pediments are manufactured out of a high density urethane, which is made to resemble wood without the maintenance required by wood products. Urethane products are resistant to cracking, splitting and rotting. They are usually less expensive than wood alternatives.
