A reinforced composite system for constructing insulated concrete structures comprising, panels having a foam plastic core between outside and inside reinforcement layers, reinforcement layers substantially strengthen the panels during material handling and construction, greatly reducing deflection of the panels between studs when placing concrete allowing walls to be filled in one lift. The optic has a body with a cavity and a proximal opening. At least one of the first portion and the second portion defines a magnet having an exposed magnetic surface area that increases along a length of the magnet. This enables simplified direct connection between IM clients when the IM server is down. The ring connectors have a generally elliptical cross-sectional geometry with a major axis of the elliptical cross-sectional geometry extending generally parallel to a binding of the binder. The connector can optionally include panel receiving means to receivingly support two rectangular panel sections in complimentary right angle relationship above or below the joined together framing members.
