Greetings All,
Is there a product that will minimize the noise from 2" PVC waste
piping that runs overhead through the ceiling? Since all of the walls
and ceilings are opened up and almost ready to be drywalled, this is the
time for some sound insulation/isolation. Can anything be wrapped around
the pipes, or is the sound deadened by filling up the stud/joist bays
with a product? Thanks in advance, Mark L.

Cast Iron as motioned ( Some cast is labeled the quiet one) If you go that
route the only tool you need is a snap cutter, Nut driver to fit the no hub
bands. Pipe must be supported 12 to 16 inches on each end. But if the piping
is done your best bet is to wrap with insulation. They also make a
fiberglass insulation for pipe (Kind of like that foam type) It's made for
any size pipe, Comes in deferent wall sizes. You would probably have to
phone an insulation contractor to find it. If any of the pipe is laying on
joist or rafters try to isolate it from the wood put a piece or thick
weather stripping under it, your trying to minimize the wood from amplifying
the sound of water running through pipes. What is the waste pipe for ? Is it
a second floor ? If it's a shower or tube try to stuff insulation under it
and around it. That made a big dereference in noise in my house. Is the pipe
drilled threw the joist?
