Ampacity rating on Romex

Is it safe to install romex 'in' insulation? IE taking two bats of fiberglass and sandwiching them around the wire which is 2 inches from the bottom of the joist. I see nothing in the NEC which would require derating th cable, but it seems taht heat would not be able to dissipate like it doe sin open air.

Thanks,
Matthew

Yes, it's safe. No additional derating is required for this condition.
