Abstract
Abstract A siding unit for a building having an outer panel and a backing board. The outer panel includes an upper marginal portion having a generally horizontal web which extends rearwardly from the face portion of the panel and which terminates in an upturned generally vertical lip. The outer panel also includes a retainer part which extends along the upper marginal portion thereof. The retainer part extends below the web of the upper marginal portion. The outer panel includes a lower marginal or butt portion which interlocks with the panel retainer part of the siding unit in the lower adjacent siding course. The backing board of the siding unit includes upper and lower margins and has its lower margin positioned adjacent to the upper margin of a backing board in a lower adjacent siding course. The upper marginal portion of the outer panel of the siding unit is positioned and retained between the upper marginal portion of its backing board and the lower marginal portion of the backing board in the upper adjacent course. Securement means are driven through the backing board adjacent its lower marginal portion and into the building structure. The face portion of the outer panel of the siding unit is spaced sufficiently from its backing board at one or more locations so as to define air spaces between the outer panel and its backing board.
