Next it was time to hang the ceiling. This drop ceiling by Armstrong was easy to use but it still took a long time. It took me two full 8 hour days to hang the entire space. The grid snaps together fairly easily and uses wires attached to the ceiling joists for added support. I hung mine with only 2 inches clearance (against the manufacturer recommendation) to gain extra ceiling height. Really happy with the result but this made it VERY trick to get all the tiles in place!
