I just stumbled onto this industrial material surplus yard. Good thing it’s not close to me or I’d be spending a lot of cash there. This high temperature insulation looks interesting. I’m not sure what it’s rated for. Apparently they have several warehouses around the country but headquarters is in Illinois.

I have discovered my inner Beavis through interpretive dance. I learned it from this tiny ad:
