Abstract
A plastic sheet exterior finishing panel is provided which includes an inner layer of foamed plastic material and an outer layer of non-foamed plastic material joined to the inner layer and defining a facing surface formed to convey a desired aesthetic effect. At least the outer layer includes at least one organic, cellulosic additive for enabling the facing surface to be painted or stained. The panel may also be supported by at least one rigid support spine disposed at least along a portion of the length of the sheet. The support spine may be formed integrally with the panel. Alternatively, the support spine may be formed as a separate material having a flexural modulus which is greater than the flexural modulus of the thermoplastic sheet so as to stiffen the panel during handling, installation and use; the separate support spine is fastened or bonded to the rear of the panel, or coextruded.
