refrigerator insulation for a Catalina 36
Cap''n, you have two basic directions you can go: either you can pull the counter off and rebuild the inside of the box from the outside, in...OR you can add to the existing insulation in one or more of the 6 sides. I chose to do the latter, one reason being that the next owner may prefer a different priority than I have (from 9 to 5 cu ft. but with 3x the efficiency), in which case s/he can just pull out what I installed.
I chose double foil-backed 1" isocyanurate foam sheet available at the time at Scotties (I think they are DOA now) and Home Depot. Easy to work with, closed cell foam, good R factor, very cheap. Don''t forget a vapor barrier on any sides you add to; getting a book to coach you on some of the issues might be helpful for you.
To finish off the interior, I lined all 5 sides (minus the top) with 3/16" PVC white sheet. Very pleasing to the eye, easy to clean, can be trimmed out with PVC trim (also at HD) using PVC cement to make waterproof joints, etc. A plastics specialist will have multiple choices of PVC and ABS sheet in stock, and will usually cut it down for you to take home, as well.
Good luck on the project!
