Your are quite the mad scientist David.

Hope you fire insurance agent is not a MLU fan !!!!!!!

What is the "stuff" used between that foil sandwich...?? some kind of fiber??

Will that fiber ignite if exposed to a flame or is it like Rockwool insulation which is basically mineral.

Now how are you going to install it to the engine cover??? Phil's idea of stiching with small gauge Mig wire using existing hole males sense. Or some kind of super glue that is heat resistant. There is a special silicon used to glue the seal around the doors of wood fired airtight stoves.

The foil covering is most effective at reflecting back infra red heat... the fiber backing is to prevent heat transfer to the other side.....

Ever wonder how a blanket or mat made of the same woven fabric as the "titanium" tape (see Jeggs catalogue) used for wrapping exhaust headers would perform. After all that exhaust tape can endure cherry red exhaust heat without deteriorating.
