Insert backer rod around jambs and head low compression, closed cell foam against the the interior plane of the RO around the jambs <br /> jamb. Push backer rod to the back of the backer rod. See figure 7b. and head jamb. This bead should contact the <br /> cavity so it contacts casing or nail fin (or in the sill sealant plane.
