Not sure how low it would hold yet. I've had it down to 58F, but that's it. I'll be figuring this out soon enough, because I plan to do a couple lagers soon. I don't imagine it will be a problem to hold 45F for fermentation, but any lower and I might be pushing it. Cheers! |

Update on mine. Finally was able to find some time tonight to make good progress. Got the wheels installed, door installed (need smaller latches, though. All wood cut and installed, and 3 of the 6 sides of foam insulation are cut and installed.
I added 6 new pics to my gallery for this project at: jboehle Album - HomeBrewTalk Gallery
I think if I had another good night of free time I will be able to finish it up. Need to get some foamed insulation in a can to fill the big gaps, glue the floor, ceiling, and door insulation on, install the latches, seal all the small seams with silicone, mount the Ranco temp controller. |

TwoHeads, you mentioned somewhere about airspace behind the insulation...what's the benefit of that?

A small gap between the insulation and the "skin" of your chamber (in my case, the plywood"), will increase the R rating. The air is just one more barrier between the hot outside air and the cold air inside the chamber. Same principle as a Thermos or double-paned windows. It's a lot harder for the heat to be conducted if there is no physical connection between the hot air and the cold air. |

No problem, and feel free to copy! You'll be following in the long tradition of copying others great ideas for a ferm chamber. Can't remember which one I saw first for my inspiration, but mine is certainly not original. Good luck, and be sure to post back with some pics of the build!
Cheers! |

Not necessary on the back wall, it's an insulated and shared wall with my house.
