Insulation, Radiant and Vapor Barriers - coccoon vs. fiberglass

Any experience or comments on the Coccoon brand cellulose blown-in insulation? Say vs. other cellulose or fiberglass blown-in?

Thinking about doing an attic and an area over a garage that's located underneath part of the first floor of a house. House built into the side of a hill. Garage is basically half of the basement. Garage ceiling is sheetrocked; finished living space above -- approach would be to cut holes in garage ceiling and blow in from there. Might already have some insulation (batts) in there, but haven't checked yet.

Thanks.

I blew in R 50 into my attic using coccoon a few months ago. Worked great with no problems cept learning how to run the blower wthout it clogging.

Don't belive the time on the Coccoon! Takes longer! Send the wife shoping for the day when you do it! Make sure your vac is working!
