Question on this type of ceiling in a basement. There are HVAC running in these both parallel and perpedicular. The span is about 19 feet about the only thing I can think of is trying this option.
In order to save ceiling height, is it possible to add a 2x4 along these joists for drywall that would hang about a 1/4" or 1/2" below the main 2 x 4?
1. What can I use to isolate the new 2x4 from the existing Truss?
2. I want to avoid a hat channel due to cost.
3. Is it even going to help or are there any suggestions.
thank you in advance
