I'm in the process of framing the soffits around HVAC ducts and plumbing in my basement using this website as a guide - http://www.familyhandyman.com/DIY-Projects/Indoor-Projects/Basement/Basement-Finishing/how-to-finish-a-basement-framing-and-insulating/Step-By-Step#step5. My original plan was to use 2x4's laid flat for the lookouts (bottom of soffits) in order to retain the most headspace in the room. However, I will have some wide soffits (mostly 4', but one at ~6') and I'm worried about sag once the drywall is installed. I have no way to secure the middle of these runs as the HVAC ducts take up the entire space.
What is the maximum length of a flat 2x4 before you have to start worrying about sag? Would flipping the 2x4's on end be my only other option?
