1) suspended ceiling: I would only need to (or want to) suspend it 2" from the bottom of the joists because anything more would be a complete waste of space. I only need to go below the level of the water pipes.
2) tile ceiling - installed on tracks which are mounted to 1/2 or 3/4" furring strips so that the tiles can be below the level of the water pipes.
Is it possible to install a hanging ceiling only 1-2" from the joists?
Is it possible to access parts of the ceiling area, if needed, after putting up the tiles that snap into place or is that really tough to do?
