Insulation for Garage: use rolls or blown insulation

I'm looking to add insulation to garage walls & maybe the ceiling (either rolls or blown insul). the large 2 car garage (27 yr old hse) is already sheetrocked & i can tell there is about 2 to 4 inches of space between the existing insul & sheetrock.
1. any opinions on blown insulation.
2. is it easy to do myself?
3. any other info would be appreciated.

Details: i live in a 27 yr old hse that has a large 2 car garage. the bedrooms over the garage are about 4 degrees cooler than the rest of of the hse. i suspect the the garage (while sheetrocked) is not well insulated. i am looking to insulate the garage, either by adding rolls of insul or blowing in insulation

 

Blowing insulation, ESPECIALLY into a confined cavity, should be left to a pro. You can rent the proper equipment, and the stuff you can rent wasn't designed to blow into confined cavities. Get a couple of quotes to have it blown in, then compare that with the cost of removing the sheetrock, hanging batts youself, then replacing the sheetrock. Since it's a garage, you'll have to use all 5/8" 'rock in order to maintain your firewalls (including the ceiling!)

 

Do you prefer cell or Fiberglass blown insulation?
