I'd rethink your insulation option..
You have R30 which is great if you have up to 9" openings... non compressed.. as soon as you compress insulation the "R" factor goes down and it's less productive...
so your spending money on something that really won't deliver as your openings between cabinet and shell is only about 3-4 inches..
Youd be fine with a R-19 which will compress a bit yes, but a lot cheaper I'd guess and deliver the same result.
I bought the R30 because the packaging was damaged . They charged me $7 for the whole roll did 3 machines with the same roll. My last machine the insulating being thicker made it much easier to install the liner. Didn't have to use any cardboard , or tape dropped right in...
