another portion of drywall was excavated to locate and caulk air leaks. the first photo shows an entire area where the air barrier was removed. this is definitely bad. it was apparently done so that the ceiling wall board would fit properly under the falling roof line. a bad mistake.
the second photograph is of the same southwest corner of the master bedroom but shows more area. thermal imaging found air leaks in the excavated areas. the areas leaking were caulked with prosoco air dam. note that the gap in the air barrier is repaired. also note the siga tape that replaces the black tape. the latter was laid down over the “mesh” used to hold the fiberglass in place. this completed defeated the purpose, sealing, of the black tape.
