I will not be using fiberglass insulation as this is a timber framed building, so no place to put it, and I'm not completely sold on iso foam. I’ve had problems with tunneling carpenter ants. They are currently in the foam in the old section. Looking at Rockwool boards.
Don't get me wrong, I can see the appeal of a heated evaporator room. I wouldn't be able to justify it. Of course I've got an 8-ft-long by 5-ft wide cupola that does a very effective job of sucking out the steam - and with it quite a bit of heat. In your case, the year round use provides further justification.

And you're chatting with someone that has a radiant slab in the chicken coop! My garage is radiant heated by my outdoor wood-fired boiler. It was an easy decision to do the same for the chickens with a circuit off from the garage feed.
