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.
