Hi, Craig.
I’ve used some ceramic insulation sheets. It looks like felt, but it’s white. I’ve found that the insulation doesn’t make much difference at all here in SoCal. What makes a big difference for me is the wind. I have a couple engines, that when running at slow speed and not very hot, even a slight breeze on a warm day can kill them. Wind barriers, or a tractor guy standing on the windward side, might do the most good. Tractor guys produce a lot of wind on their own, so you have to be careful around an open flame.
