    Enjoyed reading your book. The forward by Joel Salatin was a nice touch. Will watch for your next publication. Thank you for showing me there is someone else out there that is trying to make a difference. Kathy D.

    Nice work documenting this ambitious DIY project, Forrest. Wonder if it might make a good piece for Acres, USA, with just a little tweaking. I’ll bet a lot of other farmers could benefit from it.

    Outstanding! THAT is what I call the perfect Asset. It’s going to change your world for sure.
    I hope you share any changes you make to it in the future. I would love to see how you use it, and how it functions when all is finished.

    your photos are most excellent. really well explained. Want to come over and build a walk-in cooler at our farm next?

    Well it looks like your ground is similar to ours. We are planning to run more underground water lines etc., and have considered purchasing a backhoe, used. Looks like the one you are using is a reasonable size and yet the ole jack hammer has come to the rescue. If we still have to use a jack hammer at times maybe a smaller backhoe would serve the purpose
    I.e. a terramite. Do you think a smaller unit would have worked for you?

    Just curious, as I am looking to have a similar project done myself. What is the average temperature at your location and what is the energy consumption per month for said temperature? Thanks!

  7. Kyle

    ^ The monthly energy consumption of the walk in freezer that is.

    I Where did you get your walk in freezer door, haven’t found where to get one..We are looking to build a smaller version of your freezer. Enjoyed your site.

    Will you be running those eight fans all day and night? If so, won’t they use a lot of energy (>.1,000 watts?) and input a lot of heat into the freezer?

    Do you have a moisture barrier on the exterior of your walk-in freezer? If not, have you have any problems with condensation rotting the wood? Any suggestions as to where to find the glassboard you used on the interior? We’re an intentional community farm looking to build our own walk-in freezer. Thanks!

    the Glass board is called FRP (fiberglass reinforced plastic) avalable at just ebout every home depot in several colors

    I would be interested in knowing the energy consumption as well.

    What is the R value per 1″ thick piece of the insulation you used?

    Hi! i am planning to make my own mobile trailer freezer, looking into your project do you think i can do it as you have done and if so how will i construct the floor.

    How did you construct your door? Wood with spray foam intterior? Did you make it yourself?

    Also, is your spray foam closed cell?

    I work for a cooler manufacturer so I may be a bit biased but for the cost to implement this I think you would have been better served purchasing a cooler in panel form. I’ll state my reasoning.

    Your cost of 45,000 is about the going rate for a cooler this size if not higher for a finished cooler this size. The R value you state of 18 is what the spray foam starts at and will drop considerably as it draws moisture in. All foam regardless draws moisture. so no way around this unless 100% vacuum sealed… The amount of wood used in the construction causes problems as well allowing for mold, moisture, and swelling to take place all reducing your refrigerant efforts.

    I would pick a cooler manufacturer that used gaskete panels, no wood, and formed pre expanded foam less susceptable to moisture. I’m not doing this to promote my business so I’ll not mention it but our R-value never gets below 18 and starts at 28. Spray foam starts usually at 32 but within 8 years under most testing has been reduced to 8.
