    I am insulating my basement ceiling this week for my HT, and I am almost done (except around pipes and hvac). I am not sure how to do this as a pipe almost fills the entire cavity of the joist (at least on one side). Do you just fill the other side? Doesn't leaving the pipe bare allow sound to travel right through it? Any way to "fix" that? Also, how close can I insulate to lighting fixtures or junction boxes?

    Thanks.

    Hey Rob,

    I have the same situation. I plan on packing good old insulation really tight into the space.
