I saw the tail end of a home improvement show the other day where it looked as though they had stapled a clear plastic barrier to the bottom of the joists and were blowing in some type of insulation. I think this would be a very effective way of getting around all of the duct work, wires, pipes, etc, but I would be concerned about the insulation around and on the recessed ceiling lights I installed. The lights I installed are all insulation rated, but the lights still get hot.
Additionally, given that my workshop and media rooms are in the basement, I would like some level of sound barrier between floors and the different rooms.
I was wondering what others have done as for insulation between the basement ceiling joists for temperature control as well as sound barrier.
Your comments are appreciated.
