Thank GBAR, I was looking for this and could not find it. I will read thru that.From the maker: Walls:
3/8 (9.5) Perpendicular 16 (406)
1/2 (12.7) Perpendicular 24 (610)
5/8 (15.9) Perpendicular 24 (610)

Storing, hanging, nailing, screwing, priming before texture, etc.
Be safe, G
Actually there will be two walls. One right against the masonry exterior wall from 3 5/8" steel studs insulated, then 2 1/2" air space and another wall from 1 5/8" steel studs with two vents to keep air moving thru the wall if that makes sense.Yea I don't no why alot of them do that with the 24" O.C. There's always a little wave in the wall because of that span but maybe it's just me. Are you furring out a wall since your using 1-5/8" studs.
Whatever is easier on you both are fine.
