Hi,
I would like to build a DIY fermentation chamber like the one documented here on Home Brew Talk, but I have a question or several about some modifications. From what I've gleaned across the internet, the larger the volume of space the mini fridge (4.6 cu. ft. in my case) has to cool for three carboys, the lowest achievable temperatures will not be as low compared to a single carboy inside of a mini fridge. To resolve this issue, or to improve the ambient temperature, better insulation is the key, which brings me to my question: If 1" foam board insulation often has an R-value of R3 to R6, why not use R13 fiberglass wall insulation in the 2x4" framework and as for the liner, use FRP sheets (or silver-faced foam board insulation) for easy beer cleanup? In the scenario of the latter, would that put the R-value at R16-20??
Side note: When I build my version, I will not enclose the fridge, so there will be better heat dissipation.
Thoughts?
