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.
Thank you, that is why I ask questions here. I'll see if I can exchange it.
Also what adhesive to use on the small door gasket?
