I have been a reader of this forum for some time tring to get some ideas. I am currently framing my basement and I have a couple of questions. What should I do in the cieling? The cieling will be 8' with a 7' soffit for the duct work with I-beam construction. Is regular R-13 insulation fine to use or is their another recomendation. I know their is single faced and batt and several other options. What is the best way to install? The basement home theater room is directly below the dining and family room upstairs, so I am tring to minimize sound from upstairs to downstairs. I have heard of some people using a double layer of drywall, are their alternatives?
