  • Eggman, 25 January 2004Hi John, Once again, thanks for your time. Please have patience with me. I still don't think I have stated my question clearly enough. I think the two room info was…

  • Eggman, 25 February 2004Steve, Thanks for the latest input. I have been hunting/gathering materials and have completed the tear-out of the sixties era basement treatment. I hope to begin…
  • knightfly, 25 February 2004I'm not able to tell from the pix what Bruce used to wrap his ducts - maybe he'll check in soon and you can ask him - or you could PM him, and that might speed things…
