About this detail

A concrete floor slab interfaces with a glazed storefront or curtain wall system. The slab edge abuts a back-wrapped cold-formed steel stud framing assembly insulated with batt insulation and faced with exterior sheathing and interior gypsum wallboard. A twenty-four gauge sheet metal flashing is mechanically fastened and set in a full bed of weather barrier sealant directly above the head of the aluminum mullion system. The weather-resistant barrier membrane laps a minimum of three inches and extends four inches over the sheet metal flashing. The joint between the mullion system and the adjacent construction is sealed with a compressible backer rod and a minimum one-half inch silicone sealant bead on both sides.
