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? =)
