I have blown Cellulose in my camp works very well, is affordable, easy to install, is flame retardant and most of all, I just like the stuff.

and a DreMD top Tip if your walls aren't insulated (most of mine arn't). You can cut a small hole (1" worked at camp) and blow cellulose in. I strategically drilled holes in places that would be covered with pictures, moulding, used some outlets, installed 2 blank outlet plates. All and all made the place much more comfortable (rarely ever have the A/C on over there).
