    I need to insulate some PVC bathroom drain lines that are in the ceiling above a bedroom. I'm hoping to find a solution that doesn't require me to spend alot of money for 5' of pipe. Any ideas would be much appreciated.

    Thanks!

    I assume this means the room is already finished. If the pipe overhead is noisy, then the pipe in the wall may also be, once you eliminate the sound from overhead, which is probably "masking" it.
