Thanks for the link, and info on the tiles. My local lowes doesn't carry it .. they only carry armstrong.
Did you have much of an issue hanging the grid at all? We did it last night, it was late, and hot/humid in the room. South West Florida, 500 gal of water, inside the garage ... not alot of fun! And then trying to work around all of the equipment in there. To say the least, the grid ended up not square ... we found out today. Maybe I'll pull it down & redo it tomorrow ... the local lowes has the grid hardware on clearance ... seems like they are discontinuing it. The tiles are 3 time more expensive than what the grid cost.
