Re: Fiber glass for stuffing
I used some insulation board that I find online for free. I think it is Owens-Corning 703 or 705. It has no backing, it is about 2" thick.......
google that product and find out who is your local retailer... you might have to special order it. I also think you have to order a case of it, which about 12 2'x4' panels come with. You can always sell the rest or make acoustic panels with it. That is what I will be doing with my leftovers, especially since I am putting hardwood floors.
Good luck,
