Sealant
NOTE: Figure 16 shows a window with casing but the flashing detail also applies to any clad window product.
For installation in typical wood frame construction or brick veneer (non−recessed masonry openings), figure 16
shows the proper flashing detail in shingle style fashion. Once the exterior finish such as siding or brick veneer is
installed, a bead of sealant should be applied between the finish and the window/window casing along the sides and
approximately 1−2″
(25−51) in from the ends at the head jamb (see insert). Use a backer rod when necessary.
