Limiting the thermal conductivity by lining the inside of our vaults with a proprietary blend of a hydrogen bond fireboard and locking it in place using a stud weld process allows Fort Knox to provide the industry’s leading fire protection. Testing this process with a full 9 sensor house simulated test and showing you the exacting details in graph and product form is the only way Fort Knox vaults are tested. Others just can’t match up.
Fort Knox Vs. Other Leading Brand
"...The house was totally destroyed and we lost almost everything. Luckily, a few years before the fire I purchased one of your [Fort Knox] gun safes...I was shocked when the safe was opened and there was no damage to any of our guns or valuables."
- Steve & Mary
 
Construction and application of the fire material is a critical step in protecting your valuables. Older safes use a heat seal similar to wood burning stoves. Fort Knox uses two different seals that work in tandem with one another. First the cold smoke seal and then the Palusol seal that swells to keep the door shut. Construction matters to Fort Knox and should to you as well.
YOU DESERVE THE BEST
Fort Knox’s Inferno Shield 90 is tested to keep the inside of the vault under 350 degrees. UL Listed c-rated fireboard insulation is used on all six sides and behind the hinges to eliminate hot spots or hot pockets. Heat sensitive expanding fire seal expands to seal around the entire door on all Fort Knox vaults & safes. In addition to the high-grade UL listed fireboard and deep bend box, a dead air space is manufactured into the vault which acts as a thermal barrier, much like a thermal pane window, to give added protection. This fireproof design provides fire protection at 1680 degrees in 90 minutes.
SUPERIOR FIRE PROTECTION GETS UPGRADED
Fort Knox Inferno Shield 120 fire protection gives you the option of adding more fireboard insulation to achieve a fire rating that only commercial safes can attain. This additional fireproof protection will cause a slight decrease in the interior capacity of the vault interior, but it is well worth it! Protect your most prized possessions by adding the most valuable vault option, the Reinforced Fire Liner, and have your vault rated at 1680 degrees in 120 minutes.
