question about joist hangers with drywall - DIY Chatroom

I'm about to secure 2x10 joists with metal joist hangers, which will then have 5/8" ceiling drywall attached to the underside.

The protruding joist hanger may pose a problem getting the drywall to lay flat against the joists. Should the joist hanger be mounted a bit higher so that it is flush with the cross joist, or should the joist be flush with the cross joist, resulting in the hanger protruding downwards a bit?

The joist should sit tight down in the bottom of the hanger.

Also note that pre-hanging the joist hangers will probably not work
The joists seem to be off just enough that one will be high & one will be low
I put the joist hanger around the end, raise the joist up to where I want it, then nail it in place

If you are hanging them for ceiling joists, install all hangers first is fine. If for floor joists, flush the tops (floor) to the header joist with two toe-nails holding it there. (Then install all hangers afterwords). The framing member flushes, not the hanger. If you need really picky, champher the joist bottom where hanger contacts for hanger thickness.

If edge of the drywall doesn't break ON the hangers, usually not a problem. For example if your hangers are on a beam in the middle of a room and you can span a foot or two over them. If they're at the edge, you need to flush them or they can be a problem....
