The pink ridgid scares me a bit. Will the outer jacket not get hot? I had a warming box at work we made to keep guys lunches warm in the winter. It was a plywood box and had 2" ridgid on the inside. We had 2 100 watt light bulbs in there and a little computer fan.
It worked great for a bit. But when it was left for a couple hours and not opened it started to melt the insulation. Doesn't get over 200F in there. So I'm a bit worried about your insulation. And it stinks when it melts too.
