One of a number of horizontal boards commonly used as an exterior covering on timber-framed buildings to provide weather protection; for example, used as exterior sheathing to protect the infilling between the structural timbers. The upper edges of weatherboards are commonly tapered to a thinner edge than the lower edge so they can be overlapped by the weather-boards directly above them, or they have a rabbeted upper edge that fits under the overlapping board above, to shed water. Also see clapboards, which served the same purpose but were usually not as thick as weatherboards; also siding.
