If you want to use what pro recording studios use, as well as the manufacturers of high-end absorption panels, then you want what's known as "compressed fiberglass" or "rigid fiberglass."
Two of the more popular versions of this are the Owens-Corning 703 & Owens-Corning 705. This is a specialty item that you cannot find at Home Depot or Lowes, and depending on where you live, may have to be mail-ordered. If you can pick it up in-person at a supplier like I did, then after buying some spray-glue and fabric, you can make 2' x 4' x 2" thick pro acoustic panels for about $12 a pop! Compare that to the $50-$200 often charged.
Everything that you need to know is here: http://www.ethanwiner.com/acoustics.html
There's plenty to read & learn there to keep you busy for awhile. In fact I think that this site would be a great read for most A'goners.
I made myself a bunch of these and they much improved the acoustics of the room. And they look great too. They are also light-weight and easy to move around.
Good luck,
Ray
