Hello all, new to the forum, and looking for a bit of advice.
I have a 30x30x10 garage, and I am going to finish it with insulation/drywall. I have a couple questions about installing the ceiling.
First, I have a truss ceiling, which are 2x4's spaced 24 inches on center. I have read online that trusses move a bit over time due to moisture/temperature, and can cause cracks in the ceiling. I have also read that the best way to avoid this is to not secure the drywall within 16 inches of the wall or solid object, or secure it with slotted clips. Can any of you offer any advice on this?
Second, since the trusses are spaced 24 inches on center, should I use 5/8 drywall and construction adhesive to prevent sagging, or should I build a 16" on center grid with 1x3 firring strips and hang 1/2" drywall from that?
Last, I am not too sure how to connect the drywall to the solid wall at each end. Again, concerned about movement and cracking. There is a 2x4 nailed to the top plate on each end wall, that sticks out enough for a nailer for the drywall, (shown in pic) but it is solid compared to the trusses, should I be concerned about movement and cracking here, or just attach it anyways?
Thanks for any advice you can give.
