1. A concrete form panel sheeting comprising:
- a resinous polymer core defining a concrete-form face and an opposite face, said concrete-form face and said opposite face defining edges of said concrete form panel sheeting;
a concrete-facing surface layer attached to the concrete-form face of the core; and
a stiffener sheet integral within said resinous polymer core, said stiffener sheet being oriented substantially parallel to said concrete form face and said opposite face, and substantially transverse to said edges.

Abstract
The invention relates to concrete form panel sheeting comprising a resinous polymer core defining a concrete-form face and an opposite face, and a concrete-facing surface layer attached to the concrete-form face, the concrete-facing surface layer being adapted to be contacted by fresh concrete and to release from the concrete after curing thereof, to facilitate reuse of the concrete form panel sheeting. The invention further relates to concrete forms and form networks having the inventive concrete form panel sheeting as a component therein. The invention also relates to applications using the sheeting and forms to pour concrete.
