So firearms would actually be safer in a non-insulated steel cabinet?
Not "safer", but in most cases there's no real value in claims of the majority of non UL or ETL (and many UL) fire rated "safes" because if the fire actually reaches where the "safe" is the internal temperatures are high enough your valuables are damaged/ruined. It takes a very highly rated "gun safe" to get your guns out unharmed in a fire at the location of the "safe". Most "safes" claim fire protection because of drywall/gypsum liners that cook moisture out. They steam cook the interiors your valuables are sitting in. THEN the time it takes to get the items out while they're in that environment adds to the problem. And that's not even the fire department or sprinkler contributions. The more effective protection comes from ceramic or older concrete liners that don't cook out moisture. There are some very sad threads at THR and elsewhere about the condition of firearms in famous maker "safes" after a fire.

Cautionary note about the videos, understand that the folks opening the safes aren't gun guys or firearms condition assessors so their "those look great" comments aren't what you'd base the condition on after you looked over your guns hours or days after the fire.
