Abstract
A siding assembly and method of manufacture are disclosed. Each siding unit is a profile of a composite material which includes a thermoplastic polymer and a cellulosic fiber. The preferred siding unit has a tapered thickness and a convex face. Each siding unit is interconnected to adjacent siding units with a tongue and groove mechanism. The preferred siding profile has a plurality of webs, and the exposed portion of the siding has a capstock layer to improve weatherability. The exposed width of the siding'"'"'s face may be adjustable. The siding units are interconnected end-to-end by inserts which are positioned by means of an adhesive or thermal welding.
