I'm just about done with my Keezer but, I have a concern about R values and temperature differences. I have a 15 cf freezer that I've divided in half with some insulting material with an R value if 3.3 (6.5 doubled). I've divided my Keezer into two sections; 1 for kegging and the other for fermentation. I plan to have the entire freezer plugged into one controller that will cool the whole unit with another controller plugged into a heating unit to keep fermentation temps higher.

So my question is 3.3 or doubling the insulation (6.5) going to give me the desired 20-30 degree temp difference that I'd need?

More insulation is better, 99.9% of the time.

Maybe this will help?
How I brew: Stir plate starters, Extract, Full boil in a Keggle, 10 gallon batches.
Brewing upgrades in progress: temp controlled ferment, stir plate re-work, building mash tun, milling station

Planned House Ales: an Amber, an IPA, a dark IPA, a Mango Ale, a blueberry oatmeal stout, a dry Irish stout, a honey wheat, Apfelwien

What kind of R-Value does your ferm chamber need? -
