Same company and product line, but different compound. It is "PBC" number 7100952.

Serious question guys. My inner cabinet is installed, I'm ready to install the texolite strips but the inner cabinet is about an inch and a half too low resting on the insulation to line up. I could lift it and secure the strips but then the load of the cabinet and contents would be supported primarily by the strips. Should I shim no he it up and if so with what? Foam insulation sheets?

More insulation! You can’t support the liner with textolite strips.

My guess is the original insulation has just compressed over time. Not as bad as originally thought. About 5/8ths of compression. Will be heading to Lowe's tomorrow to find some foam insulation. Should I put it under or over the original insulation?

Rick,
If you have it apart replace the insulation. There’s no benefit in keeping old insulation.

Rick appreciate you wanting to keep it as original as possible but you have to draw a line . I replaced all the insulation in my ck , thought of it as the same as replacing wiring . Why would you not go with something Better?

Rick,
I understand your desire to keep it original, but wiring and insulation deteriorate or have improved over the years. I have never completely disassembled a cabinet. Therefore, mine are original. When I do get off my lazy butt and restore some of my fridges, they will get new insulation.
New insulation will keep the moisture out and reduce rust. It will also reduce electric use. Now I don't give a damn about that, but in doing so the unit will run less and might last longer. That's the goal. There's always someone with their heat or a/c on and the door wide open negating my energy savings (if I cared) for the entire year.

I have no idea what "envirosheet" is made of. But I would strongly suggest avoiding anything containing chlorine (PVC, etc.) for wiring insulation, vapor barrier, insulation, tubing, whatever. I've seen copper corrode from long-term contact.
Personally I would recommend polystyrene (genuine Styrofoam blue board). I looked into it in depth for underground insulation in our berm home. It retains full R value after 40 years buried in earth. Comes in various thicknesses (mix or match for desired thickness).
Do not use bead board! I also do not recommend urea board.

I second that. Extruded polystyrene boards is probably the sweet spot between cost and performance. Expanded polystyrene (the white stiff that is made of lots of little beads packed together) would be fine too in that application, but less desirable. Ideally, tape the seams to seal off air flow. Different sizes can be sandwiched to get the desired thickness.
That should result in approx 30% better R value (more or less), and corresponding longer cycle times.

Well I went with the expanded polystyrene because my Lowe's didn't have the extruded in 4x8 sheets. I have the bottom pieces cut and fitted. Would you experts recommend gluing them together? I have spray 3M contact cement I was thinking would work but I also know polystyrene can react badly to solvents.

If you're referring to 3M Super 77, don't do it. It'll dissolve eps.

Tape works best with foam boards, 3M sells an all-weather tape (8067 or 8087) that works good. Flashing tape (like the 8067) is best, but any tape for insulation and sheathing should be fine. Avoid the ones that intended for specific brands of house wrap.

Rick, If you have it apart replace the insulation. There’s no benefit in keeping old insulation. Thanks for pushing me to do the right thing. I thought about it and figured this machine will be with me until I'm gone so why worry about originality for the sake of performance and longevity. Longer cycle times will hopefully mean longer life.
