The "R" rating is much better and is the same thing used in a refrigerator walls but is sprayed in. If a refrigerator has only 1.5 to 2 inches and you double that it would be very efficient. It does not look like you put foam on the bottom? This is very important and should be added because cold goes down and radiates out the bottom of the cabinet. In the long run the more insulation you have the less the refrigeration runs and you save more money.

Ref: Foam and Foam Board Insulation
I took a look at 4.9 and 7 cu/ft chest freezers at Home Depot, measured 2 3/4" to just 3" thickness total side, back, front, bottom (best I could) and top of their freezers. All their posted dimensions are outside dimensions, this can screw a person up thinking their corny or keg count amount will fit. Check tose internal dimensions before ever purchasing a freezer. I recall a thread with carboard disks cut out for corny kegs to check the corny keg amounts per different chest freezer brands and sizes, a darn good idea. The depth of the freezer allowing for your tap fittings to clear the lid when closed is a must unless your planning on adding a collar as my friend went to Sears using their outside dimensions and screwed up purchasing a too small of a chest. Buy the right one once or build to your needs.
Hey Death Brewer; what's the BTU's of that AC unit your using?
Will it pull down and maintain temps if in a 80 degree room all day
inside a house? My 10' x 10' basement is the coldest part of the house
reaching 72-74 degrees when we have those 92 degree bay area temps.
This for the fermenting unit not a keezer bier tap. DeathBrewer a PM sent to ya.

5000BTU...I bought this guy for $100:

Zenith 5,000 BTU Room Air Conditioner - ZW5000 at The Home Depot

I went cheap. If I did it again, I would get something better. It struggles a bit to keep it at 58F and if I turn it any lower, it's on almost all the time. Still works great, tho...My hefeweizen was fermenting at 63F yesterday and the ambient temp is about 75F.

This is cool! I would crawl in there on the hottest days of summer lol.


Just noticed this thread was old but with summer coming it might be a good bump.

I did something very similar, 4x8x2 feet. I love it and as of yet don't have a need for a freezer.

Fermentor I built this weekend. Waiting on my temp controller and going to cover the insulation on the doors. Thinking about doing a porter with lager yeast this weekend.

if you're worried about melting the foam, a thin layer of something that insulates might do it, like a rubber or silicone gasket/sheet where the paint can attaches to the chamber?
