Sounds like I'm good to go.


Sorry i hadn't seen this earlier or i could have replied.
This is pretty standard practice for running vapour barrier into the joist ends or at the ceiling, however most builders don't bother with the acoustiseal caulking. I however do and thankfully, (but with exception in our basement), the rest of our house was constructed in this method. I was pleasantly surprised to find the tarry black substance while drilling down from the attic into a wall stud below.
