garage insulation

I have an oversized detached garage that is currently not insulated. I am thinking of insulating it. Not sure what insulation to get.

The same for rafters and wall?
Should i insulate the rafters, i will lose above storage tho =(. or deal with just doing the roof with styrafom?
What r- value is necessary?
What type of insulation is best for rafters and walls? Brand?
And what is the difference between all the backing types? And what should i use?

I am clueless to when it comes to insulation as you can see.

thanks for your help....

First of all heat rises. So insulating your ceiling or between the trusses is imparative for good insulation and cost savings. Forget the styrofoam. No e value in it to speak of. I used R-36 in my garage ceiling, paper faced on one side, and stapled up. Faced insulation means it has paper on one side or both. In your walls you will use either R-11 for 2x4 walls or R-19 for 2x6 walls. Hope this helps. Good Luck
