I'm planning to lay some flooring in my loft. It's an old cottage and the ceiling below is lath & plaster attached to small (approx 2" x 2") timbers. These in turn are attached to the bottoms of chunky (3" x 10") oak beams running in the opposite direction. The distance between oak beams is 1.6M.
If I lay new joists (50x100) across the tops of the oaks, I lose some valuable height so I'm considering using hangers to drop them down to the same level so they sit flush with the top of the oak beams. Is this a good idea? If so, should I make them absolutely flush? I'm concerned that the part of the hanger across the top of the oaks (and the nails in it) could cause issues getting the TnG chipboard flooring level.
Many thanks for any assistance
