About this detail

This architectural detail shows the head condition of a nail fin window integrated into a rainscreen wall assembly. An aluminum window frame features a fully welded window flange set in a bead of sealant, with a non-rot one-quarter-inch shim made of HDPE Starboard or Extira. A starter bar with ember protection WDM 98 mesh sits above the window. The wall assembly incorporates fiber cement panels over one-half-inch hat channels installed per manufacturer specifications, creating an air gap. Waterproofing layers include a fluid-applied water-resistive barrier, Perm-A-Barrier Ultra self-adhered sheet membrane extended six inches minimum, and stainless steel through-wall flashing with sealant and backer rod at joints.
