Abstract
Metal faced insulated inserts have interior and exterior surfaces with parallel longitudinal edges between an upper and lower short edge. Each longitudinal edge of each insert has two deep recesses and a central shallow recess. A plurality of generally I-shaped concealed locking beams have a central section and parallel end sections. Each end section has a central region of a thickness less than end regions to form a locking ramp. A pair of similarly configured metal facings for each concealed locking beam with opposed end parts are located within the deep recesses at the longitudinal edges of each insert. Each end part terminates in a V-shaped projection configured to allow the end regions of the concealed edge lockings to compress the V-shaped projections and allow the end regions of the concealed locking beams to mate with the metal facings.
