I just started a keezer build for my GE FCM7SUWW 7 cuft freezer. I'm building the collar out of solid red oak, and have a question about how people are installing the insulation. The collar thickness is 3/4", and I installed another 3/4" lip at the top, and I was planning on putting the 3/4" insulation under that so it'll be flush all the way down on the inside. The insulation I got is Perma R, the stuff with one side that looks like aluminum foil. I would like to have this side visible, but wasn't sure if that was the right way. Is there a difference in R value if it's installed one way or the other? The only info I could find about which way is right talks about the dead air space, which doesn't really apply here I don't think. Here are some teasers so you see what I'm talking about with the lip. I'll be posting some more pics as the build progresses. Thanks for any info on the insulation!
