3mm plate replacement BBQ tray for brick built BBQ. Last tin one didn't make it through winter.
Replacement charcoal tray for large brick built BBQ.
Well any sort of insulation will do and a well designed rocket stove will have an insulated firebox as well as an insulated flue. Just a short section say half a metre would do, typically a standard 5 - 6 inch pipe, wrapped with insulation or enclosed in fire cement.
Plenty of designs out there, just look for one that's got the right sort of insulation and the designer looks like they know what they're on about. Its a big subject mind and I'd want to see one that also has a secondary air inlet among other tech stuff.
They can be so efficient, all that comes out of the flue is hot air and water vapour.
beware on what insulation that you do use either use perlight or vermiculite
you dont need insulation on the flue its more on the burn chamber
as goes for secondary air it can have its problems in the wrong place it wont fire well or draw badly too big of secondary air pipe and your system cools
