For anyone who is burying ducts in blown-in fiberglass, I hope They can be very first insulated with duct insulation equipped which has a vapor barrier. Normally, the ducts are going to be dripping damp throughout the summer months months.
Many thanks for your response. It's possible what exactly is baffling to me, no less than, is the "shiny floor" which don't just displays mild, and also demonstrates warmth.
