I don't think so. We had fire sweep through; I never heard of one safe protecting contents, out of thousands of structures. In every case I'm aware of, the contents were heated to the point of melting most metals, and reducing all papers to ash. Maybe not melting firearms, but definitely rendering them useless. In many cases, the safes failed to the degree you could kick them apart. Regardless of insulation, when you put a container in a 1,500 degree environment, the stuff inside is going to be wrecked. Maybe there are some models that would have worked, but I wouldn't trust any of them.
