Permanent Kettle Insulation

[Jetpack_Maniac]

I have been toying with the idea of using a spray-on ceramic insulation on kettles or other brew gear. I'd do the walls and the lid but leave the bottom exposed. I currently use electric but I'd leave optionality open. Layering insulation can be quite a pain so the idea of convenience and permanence appeals to me.

Is this something has ever done?

I put insulation on a metal mash tun that was 1" rockwool insulation wrapped in sheet aluminum. The exposed insulation on the top and bottom was covered in RTV silicone. I made it to be removable if necessary but I never did. I do think that wrapping a vessel with 1" of closed cell foam with some velcro closures is easy enough.

That sound interesting. Do you have pictures of the setup?

Fitting the aluminum sheet and compressing it so I can rivet on the draw latches.

Rockwool isn't super flexible, but it will conform with some persuasion.

RTV silicone filling the gap, about 1/8" thick...
