Drilling through wood panels

[paulga]

i was thinking something like this:
View attachment 145606

is this sleeve good for exhaust pipe insulation?

Thanks for the drawing!

what does the stand off pieces look like? it seems they are spacers between the shield and the wood panel on the back

on the sketch i put broken sides for stand off. you can use plain flat sheet instead and use just about anything for spacers to stand it off from the wood panel. maybe little blocks or rounds of aluminum or hard ceramic stand off spacers.
here's some aluminum ones: https://www.amazon.com/Aluminum-Len...27027&s=industrial&sr=1-4&ts_id=16413321&th=1

there's a few options for exhaust sleeve.
here's a silicone option: https://www.lubricationspecialist.com/exhaust-components/silicon-fire-sleeve/

or this fiber one: https://www.heatso.com/exhaust-hose-lagging-insulation-1-meter/

so the offset sides work as stand off pieces.
is a 0.8mm (22 gauge) sheet thick enough for a shield?

yes, that should be plenty thick to do the job.

here's a silicone option: Silicon Fire Sleeve: Espar Heater Parts, Diesel Truck Heaters - Lubrication Specialist

or this fiber one: Exhaust hose lagging (insulation) 1 meter

@Bmarler is the lagging wrapped on top of the sleeve? or directly around the exhaust pipe without a sleeve?

silicone sleeves seem to have an operating temp up to 500F (one example, also this one), but the exhaust temp can get higher than that (500-600F) : see Forced Air Diesel Heater Exhaust Pipe

why is this PAN sleeve that has a much higher temp rating not a good choice?
