I have 9 foot walls in my basement. I intend to put a drop ceiling in at 7.5-8 feet.
If drywall is stacked vertically at 8feet tall, there will be a gap above the ceiling between rooms.
Putting sound-proofing etc aside, does anyone know if code allows this gap, or do all rooms have to be sealed from one another above the ceiling? I already have a lot of mechanicals (ducts, gas lines etc) running thru this space so some areas cannot be sealed with drywall.
I am checking with local code, but wanted to get a general idea first...
