This exterior wall assembly features formed metal panels mounted on horizontal panel rails connected to a thermally broken rainscreen attachment system, with sizing and spacing determined by the delegated design engineer. A fluid-applied air and weather resistive barrier coats the exterior face of five-eighths-inch gypsum sheathing. Mineral wool board insulation fills the six-inch stud cavity. The interior is finished with one-half-inch gypsum wall board. The complete wall assembly achieves a maximum U-factor of U-0.065.
