Body:
-3-1/2" thick, consisting of 1/2" plate steel with a unique proprietary fire and burglary resistant material.
-Dual seal design utilizes a silicone foam seal with a heat-expanding intumescent seal.*
[The root word, "intumes", means to react by expansion. When the intumescent seal is exposed to high temperature (above 250oF), it expands to as much as 8 times its original thickness. In this
expanded or reactive state, it has very high thermal insulating capacity and resistance to breakdown. This provides a strong positive seal between the door and body, preventing heat influx.]
