About this detail

An aluminum storefront head frame interfaces with a twenty-four gauge two-piece sheet metal head flashing with a cleat and a painted carbozinc finish, sitting below a seven-eighths-inch exterior cement plaster system. The head member is fastened using quarter-twenty hex washer head self-drilling screws spaced at two inches from the ends and eighteen inches on center per ICC ESR-3332. Sealant is applied at the perimeter joint between the framing and the plaster return. Glazing pockets and internal thermal breaks such as TB433 and TB430ST are detailed within the extruded aluminum sections.
