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.

The fibers aren't that big an issue. If you want better heat tolerant fibers you can use basalt fiber. The problem is the matrix, which softens under heat unless you use exotic things like ceramic matrix composites which are brittle.

  Asbestos is rock.

    And rock is as heavy as rock.

Some casual googling earlier suggests to me that fiberglass ladders are fiberglass/polyester, not fiberglass/epoxy.
