Insulation works both ways brother. It might help keep it cool, but if it heats up, it will help it stay warm too.

I'll send an email off to a friend who doesn't post here to see what he ended up deciding on using for his similar project (he's a PhD physicist, so I'm pretty confident he researched the hell out the coolers before he settled on a type/brand/style)
