I bought a massive roll when I thought I was going to buy an empty van. I found one already mostly insulated so I'll need only a little bit. If you'll be there or in the area I can sell you only what you need. I believe it was 1.5 inch thickness once fluffed out, not sure might be 1.75. I can't get to my Amazon acct at the moment but will soon to update the specsfor you.
