Itech Thermal Response (ITR) represents quality assurance to specified products in providing controlled results in fire testing.

Fire safes are designated as fire resistant (not fireproof), which entails a different temperature rise in the furnace during the endurance of the test.

The fire safes, standing upright, are monitored and measured using ceramic thermocouples placed throughout the safe to give exact temperature readings, providing you with the assurance that your Heritage safe will perform should the unthinkable happen. The classification is a result of the external safe temperature (not the furnace temperature, as promoted by some tests).

Test failure occurs when the safe's average internal temperature reaches 350º F. Paper products will char at approximately 420 F. A certified testing furnace is rated at 1950º F, generating 36 million BTU per hour of scorching heat, exposing both radiant and convection heat transfer to the safe.

A typical home fire is estimated to reach between 800º F and 1200º F. Depending on the fuel in and around the home, the typical response time for authorities in reaching and containing most home fires is 10 - 30 minutes.

Pyro-Shield Thermal Blanket

The Pyro-Shield Thermal Blanket is placed in the top of each Heritage safe, where the heat is often the highest, for increased thermal resistance.

Palusol® expands with development of foaming pressure under the action of heat. In the process a fine porous, compression resistant, non combustible, heat seal is formed. This seal fills joints around the safe door to provide superior protection against smoke and heat.
