Just the kind of stuff I was hoping to find.

Is that 74˚C?
Searching amazon for "Car Hood Engine Firewall Heat Mat Deadener" brought up several offering from UXCELL. Delivery Monday is better than late July with aliex.

In the past I used reflective bubble wrap roll like this one, when I wanted to print ABS on an open frame printer.

I had looked at some of that bubble wrap but was concerned about flammability. The Car Hood Foam seems to be flame retardant. Does the bubble wrap sustain fire?

@brs The stuff you are looking at is generically called "Multi Foil Insulation" here in the UK. So you might find something suitable at a better price if you use that as a search term.

Yes, providing you do a good job having a low leakage box, have some convection/circulation fan and keep the volume down, 74degrees C is achievable with the rubber foam insulation I describe.

@brs Where are you based. I have quite a lot in stock I could share.

I don't know. I don't have a piece at the moment, otherwise I would test it.

@zapta I just tried burning it with a blow torch. It extinguishes within 1-2seconds once the torch flame is off which seems good to me. However, it would be good to know how to test this against standards such as UL94 or equivalent. Perhaps someone can advise?

Washington State but never mind as I ordered some on Friday evening, it arrived early Saturday morning and it was installed Saturday afternoon. Got the 5mm foam and I also put a torch to a bit of it and found that it did not sustain flame once the torch was removed. Thanks though.

@bubblevisor, if yo will buy from a repuatable vendor or manufacturer, you may find safety information you can trust. E.g. https://www.mcmaster.com/insulation/insulation-type~sheet-strip/heat-reflecting-air-bubble-duct-insulation-sheets/
