I'm in the process of enclosing my garage. The bottom foot of one of my garage walls is a slab step. Under the drywall on the top part is a one inch thick layer of rigid foam. I need to cover up the bottom piece with drywall, but I'm unsure how to hang it over concrete and still be up to code. I'm thinking of attaching 1 x 2 furring strips and hanging the drywall on those. Is this the right solution? Are there any moisture/insulation concerns with that method in Florida?

1x2 furring strips will work but should be pressure treated. I'd also go the extra "mile" and use green or other moisture resistant drywall.

  • Second this answer. Construction glue attach a 5/8 or 3/4 treated wood plywood or wood strips. – JeffFromCanada Oct 12 '18 at 17:19
