Hi Bob, the stuff you are using I think it is Mylar coated fiberglass. If it is close to the exhaust pipes, it may melt the coating? Friend of mine bought some from Spruce. I put the propane torch on it and the coating melted instantly.

You can tell Mylar film because even a match will do that. It's just poly film with a thin (basically painted or sprayed on) coating of aluminum. 99% plastic. Worthless for insulation near any form of heat source, and almost always labeled as "flammable".

But, Buly, a propane torch is over 3000degF. Way above the 1000F Bob quoted for his material. Not a very fair test, is it? =)
