About this detail

The junction at an entry wing wall incorporates cold-formed steel framing and exterior finishes. The wall assembly consists of 6 1/2-inch steel studs with batt insulation, five-eighths-inch glass mat exterior gypsum sheathing, a fluid-applied water-resistive barrier, one and one-half inches of continuous rigid insulation, building wrap, seven-eighths-inch hat channels, and a flush plank siding system. A movement joint is incorporated with a pre-formed ultra-low modulus silicone rubber extrusion sealed to the water-resistive barrier and covered by the flush plank siding. The window interface features an aluminum frame with an integral sill pan, metal flashing sealed to the water-resistive barrier with corner end dams, compressible insulation, and a granite sill below supported by blocking and backup sealant.
