About this detail

The storefront head detail incorporates a deflection head track above the storefront system, coupled with a window covering and a two-inch backer rod and air seal sealant. The assembly integrates foil self-adhered membrane (FOIL-SAM), air-water barrier (AWB) taped at all edges, and pre-finished metal head flashing (PPM). Type 1 metal panels clad the exterior above, sequenced with stepped sealant applications. The sill detail features a 3/4-inch wood sill over the substrate, a color-matched one-sixteenth-inch thick aluminum angle, and sill trim with continuous sealant air seals. Flashing and membrane installations follow a sequential layering approach referenced from the window flashing sequence sheet.
