The present invention provides for a starter course for an exterior insulation panel application. The starter course has an outer surface, an inner surface, a lower edge, an upper edge and side edges. The outer surface is generally planar. The inner surface is provided with raised structures to provide drainage channels there between, the raised structures being provided over at least the upper half of the inner surface of the starter course. The raised structures extend across the starter course from one side edge to the other and from the upper edge to at least half way to the lower edge. The portion of the inner surface from the lower edge upwardly to about half way to the upper edge is free of the raised structures.
