A vertically elongated module of sheet metal has a center panel with side flanges turned inwardly along each edge, and with narrow return flanges on the free edges of the side flanges. The upper and lower ends of the return flanges have tabs turned outwardly to the center panel, and the upper and lower ends of the side flanges are turned laterally as end flanges in lapped relation to the tabs. Turning of the end flanges leaves transverse flat nailing strips along the upper and lower ends of the module. The side flanges are of less width than the width of a standard 2x4. When erected into a wall, successive modules are secured in side-by-side relation on the wide side of a 2x4 plate by nailing their lower nailing strips along the narrow side of the lower plate, and an upper 2x4 plate is similarly secured to the upper nailing strips. Furring strips are secured along the inner sides of each pair of adjacent return flanges, with the ends of the strips abutting the plates, and with the inner sides of the furring strips flush with the inner edges of the plates. Inner panels are secured across several furring strips with the ends of the panels lapped on the inner sides of the plates. The inner panels have holes near their tops for introduction of insulating material.
