Wikipedia
Bargeboard (probably from Medieval Latin bargus, or barcus, a scaffold, and not from the now obsolete synonym "vergeboard") is a board fastened to the projecting gables of a roof to give them strength, protection, and to conceal the otherwise exposed end of the horizontal timbers or purlins of the roof to which they were attached. Bargeboards are sometimes moulded only or carved, but as a rule the lower edges were cusped and had tracery in the spandrels besides being otherwise elaborated. The richest example in Britain is one at Ockwells in Berkshire (built 1446–1465), which is moulded and carved as if it were intended for internal work.
Bargeboards are pieces of bodywork on open-wheel racing cars, serving a purely aerodynamic (as opposed to structural) function. They are curved vertical planes situated longitudinally, between the front wheels and the sidepods, held away from the chassis at the front on struts or other connectors, and connecting to the sidepods or extensions of the floor at the rear. In general, they are significantly taller at the front than at the rear making them trapezoidal in profile, and they curve outward in plan view, being closer to the centerline of the car at the front, and curving out towards the rear.
