Attaching dry wall to ductwork

My son in law had a large addition made to his house which resulted in ductwork to feed the addition running below the joists in an existing basement powder room. He now wants to put a ceiling in the room but does not want to lose anymore head room. He wants to attach the drywall directly to the ductwork. I am not sure if that is a good thing to do, has anyone ever done anything like this??



thanks

Jack P.

No he doesn't. Not really.

Apparently this is a hard ceiling. Build a frame from wood. Not sure what exactly you have going on but you can use 2X to build frames for each side of the duct and then run 1X underneath the duct to tie the sideframes together and attach the rock to. You need to leave a small amount of room for the duct to expand and contract or it will make noises as it tries to move within the wood.

That 1 1/2 inches would be nice but it;s not a good idea to mount rock directly to the duct.

Thanks NAP. I didn't think it was a good idea but I was thinking about the wieght, not expansion/contraction.
