US Patent 8621810 Building wall system

A building wall system has a plurality of panels positioned adjacent one another for securement to a frame structure of a building via a plurality of fasteners. A plurality of rails secures a façade to the panels. Each rail has a first, second and third portion. The first portion receives the fasteners to secure the bracket to the frame structure. The second portion provides a surface for securement with the façade. The second portion is spaced from the panel so that fasteners do not enter the panel. The third portion rests against the panel to provide rigidity for the rail.
