Abstract: Door and glazing frames include intumescent material positioned in a dado that is formed in a jamb side surface. Trim materials are positioned over the intumescent material to improve the appearance of the frame and to prevent tampering with and damage to the intumescent material. The jamb trim is preferably made of a cut hardwood panel having a thickness that allows heat to be transmitted to the intumescent material in the event of a fire so that the intumescent material will expand and fill a clearance space between the frame and the door or glazing. The expanded intumescent material inhibits the transmission of smoke and heat between the door and door frame. After expanding, the intumescent material will char and solidify, which may provide an added benefit of structural support for the door and or glazing.

Abstract: A thermal barrier fabricated from pumice, or pumice-like material, and a suitable binder is provided. It may be formed as a self-supporting or load-bearing structural member, or as a thick coating for IR signature reduction. A first embodiment may be used to build a structure, e.g., a room onboard a ship that serves as an effective thermal barrier. Should a fire start in the room, the thermal barrier prevents rapid spreading of the fire and provides crews additional time to fight the fire. A second embodiment, as a thick coating, reduces the IR signature of a radiating body, such as an exhaust stack, by a factor of four. This thick coating helps shield an object from IR surveillance devices or seekers, resulting in much shorter acquisition and tracking times for these IR devices and seekers. In addition to benefits as a thermal barrier, structural members using concepts disclosed for this invention may provide inherent blast and shock resistance.
