Hi!
I've seen a thread on that some days ago, but I'm still at a loss.
I have bought a Coleman cooler (2 gallons) for small batches. The lid is not insulated (i couldn't find any cooler with an insulated lid at this size). I have tried aluminum foil and styrofoam and blankets, and tested with water at mashing temps. I still get a 10°F loss over an hour at best.
Now, I'm thinking about spraying the lid with insulating foam (polyurethane), but I'm unsure about the toxicity? There is a lot of water that condensates on the lid and drops back down in the mash...
