Has anyone closed the open gap to the double wall insulation?

Looking at trying to stuff high temp insulation around the perimeter of the double wall. The double wall is open to the internal temperature of the grill, so in my opinion useless. The air barrier is at the same temp as the grill. If the gap could be closed I think it would act as a true isolated air insulator.

Yup, I went ahead and inserted insulation, then sealed the gaps with 1" graphite impregnated glass gasket rope. The internal plates are easy to remove. I'm about to post up the project.

I'm 19hrs into a slow smoked brisket, the barrel was literally cold to the touch this morning after 12 hours. Saves pellets as well, more efficient.

Are you doing the lid also?
Also if you don't mind what was the length of total rope needed?
1/2" or 1" thick insulation and will (1) 24 x 36 roll cut it?

This is the insulation I was looking at using

Ceramic Fiber Insulation Blanket Roll (6# Density, 2300°F) (1in.x24in.x60in.) for Kilns, Ovens, Furnaces, Forges, Stoves

I used 1/2" ceramic blankets and 12ft of the 1" rope.

I just completed my post on the project here;
