Best way to install 2-layers of Drywall on RSIC ceiling and walls
I'm going to be installing drywall to my rehearsal space over Christmas break. I am using RSIC-2 clips ordered from PAC International and I already have the 5/8" fire rated drywall ordered and ready to deliver on Dec 26th.
My question is, what is the best method to install the drywall? I've seen the staggered method with backer rod between each ceiling-to-wall and wall-to-wall connection point. But I've also seen where people install both layers of drywall on the ceiling first and then the 2-layers on the walls, still with backer rod between all ceiling-to-wall and wall-to-wall connection points.
What is the preferred or best option? The main reason I want to know is I want to make sure my last layer of drywall matches up with the center of the hat track to be able to install the maximum amount of full 4x8 sheets of drywall.
For example the last sheet on the ceiling using the staggered method will start 2.625 inches away from the framing member (using RSIC-2 and 5/8" drywall), putting the 'drywall edge' hat track at 50.625 inches from the wall framing member. Whereas just installing both ceiling layers first I just need to make sure I have a gap (thinking 1/2 in) from the wall framing members, putting the 'drywall edge' hat track at 48.5 inches.
I think 2 1/8" is a big difference in where to install the 'drywall edge' hat track and won't allow the first piece of the last layer on the ceiling to be a full 4x8 sheet of drywall without having the butt joint of the next piece not be on the hat track.
I may be over analyzing this ...
As far as the whole project I'm in a basement with 8ft high walls and I have properly isolated the HVAC system, light fixture, power outlets, and will be correctly treating the window and door per Rod's book.
