The ceiling in my office and my (soon to be) baby’s room are sagging and in disrepair. I’ve finally decided to take them down, run new electrical, ceiling fan boxes, recessed cans- the works. And no, there’s no detail or molding being destroyed! just flat, saggy, cracked plaster.
\nMy plan is to clear out the plaster and lathe, cut homasote to fit between the joists, then a layer of 1\/2″ ply and screw 2x4s against the existing joists to snug the whole thing up against the floor above . Hopefully this will both shore up the sagging and creaky floor in the baby’s room ( no subfoor- just pine planks against the joists) and provide some soundproofing. After that I’ll add a layer of R13 fiberglass or denim insulation and seal the whole thing up with 5\/8 rock.<\/p>
The questions:
\nA) does that sound like a reasonable plan? I’m hoping the homasote will absorb at least some of the sound that transfers from our home into our neighbors home ( narrow houses with continuous shared joists).<\/p>
