The glycol chiller is getting there and it's time to start wrapping copper tubing around my fermenter. I have a bunch of foam to wrap around it, but it's going to absorb water that condenses and long term, it's not a very viable solution. Does anyone have any better suggestions to insulate my fermenter?

For reference, this is what I have

You could use closed-cell foam.

You could suspend this thing inside a larger container and fill with expanding urethane foam. Not the stuff in the little can, the stuff for retrofit wall insulation.
