Flatting out ductwork ...
You need to maintain the same number of square inches. If the
existing is 6" round, the square inch capacity is about 27 square
inches. Stop at any tin shop, explain your problem, ask them to
make a transition that will work.
If you are framing a wall directly under the glulam, add two lally
columns that are swallowed by the wall and go through the glulam.

Trying to finish a basement, and where we intend to put a
partition
wall with a door is right where a contractor left a 6" duct
below the
floor joists. He did this to go under a piece of microlam that
is
used of support in that part of the house.
I know better than to cut into the microlam, but can I purchase
a some
ductwork that will flatten out in the area where it will pass
under
the microlam and hug the ceiling ?
If I could recover 2" I could install a standard interior door
without
modifications.
Thanks
