Abstract: An insulated wall finishing system consisting of several components all of which have a central core made of rigid foam core material such as EPS foam. One or both sides of the central core are laminated with a gypsum product, formica, wood or wood by-products. The components consist of a straight wall panel, a corner column and Partition “T”, when combined and interconnected allows the installer to construct a perimeter wall and interior walls. Each wall panel further contains a plurality of right-angled metal supports oriented vertically within the panel, which allow for more rigidity and also offer a point of attachment for heavy objects such as pictures, cabinets, televisions and similar object. Each wall panel further contains a plurality of vertical holes or chases oriented vertically within the panel to allow for the routing of plumbing, electrical and audio visual utilities within the panel.

Abstract: Cathodic protection to prevent corrosion of embedded steel, e.g. reinforcing rods in concrete, is obtained by applying a graphite-alkyl methacrylate composition to the exterior of the concrete.
