How are commercial aircraft insulated and what kind of fire barrier material is being used? How much insulation is required in a typical Boeing 747 vs. a Boeing 787?

    $\begingroup$ most of what is on the aircraft is not flammable, you don't want some faulty wire torching the entire aircraft $\endgroup$ – ratchet freak Nov 16 '14 at 18:41

This article from Boeing describes fire safety on their planes, and they mention "fire-protective insulation blankets." A quick google search suggests that in non-aviation contexts, these are usually ceramic fiber. So it seems likely that at least one form of fire insulation in modern transport-class aircraft is ceramic fiber fire blankets.

  • $\begingroup$ foil-backed fiberglass is (or at least was) also used, and there are foam insulation products that are popular because unlike ceramic/glass fiber insulation they don't kick up irritating fibers when you cut and work them. $\endgroup$ – voretaq7 Nov 17 '14 at 17:53
