    I've got anywhere from R-11 to R-19 right now.

    Most of the ductwork (the larger/longer runs, anyway) is hanging, bottoms 18" or more off the floor, so burying isn't an option unfortunately.

    Great- thank you for that. Should I ask that the box be replaced, as it seems like shallow board and it's definitely soft and pliable at this point? Or is it enough that they seal up the leak?
