I looked up g11 and g10 for their structural heat limits, because I know they have a higher heat resistance than most fiberglass, and are limited to around 150c/ 300f. I looked up what a typical house fire burns at which is 600c/1100f.
This is actually a great case where asbestos shines. It's nonconductive and can stand very high temperatures. If not for the whole cancer thing.
