I've just finished framing out my basement to double our living space. It's new construction with just a large poured rectangular concrete floor between cinder block foundation walls.
The walls turn out to be just shy of 8' from floor to ceiling. I plan to put in a suspended ceiling later so as to be able to get to all the wiring/plumbing if necessary in the future.
My question is: Should I hang the sheet rock vertically or horizontally? I've been careful to make sure that all the studs are exactly 16" on center. I've heard that horizontally produces fewer joints, but that also produces those nasty hard to hide 4' butt joints. If I hung vertically, every joint would be flush.
Many of the walls are longer than 12', and since it's just me doing the work, I don't think I have the strength to handle sheets that big.
I'm planning on doing the hanging and then bringing in a pro to do the mudwork.
Related question: Should I hang the sheetrock a smidge - maybe a half-inch off the (concrete) floor, just in case of water leakage?
Would horizontally hung sheetrock make for a stronger wall?
Any other tips?
