Fire rated door and fire rated window

DETAILED DESCRIPTION The invention teaches that the foregoing object can be accomplished by a fire rated glass door assembly configured to inhibit the spread of fire and smoke in the region of a wall of a building, said fire rated glass door assembly comprising a fire protection partition of a building; a door jamb; said door jamb comprising a substantially contiguous and unitary frame structure; said door jamb being configured to be disposed in stationary manner in said fire protection partition of a building; said door jamb comprising a material to provide said door jamb with a fire rating and thus with the capability to withstand fire a predetermined time with a predetermined fire temperature on the fire exposed side of said door jamb and a predetermined maximum temperature on the non-fire exposed side of said door jamb; at least one door leaf; sad at least one door leaf comprising a glass pane to provide said at least one door leaf with a fire rating and thus with the capability to withstand fire a predetermined time with a predetermined fire temperature on the fire exposed side of said door leaf and a predetermined maximum temperature on the non-fire exposed side of said door leaf; said at least one door leaf comprising a substantially contiguous and unitary frame structure; said at least one door leaf being configured and disposed to be mobile in reference to said fire protection partition of a building; said at least one door leaf being disposed, upon assembly, to be at least partially enclosed by said door jamb; at least said door leaf comprising a first side and a second side to form a compartment therebetween; said compartment extending over a substantial portion of said door leaf; and a material being disposed in said compartment; said material in said compartment comprising a flowable material to impart to said door assembly a fire rating and thus with the capability to withstand fire a predetermined time with a predetermined fire temperature on the fire exposed side of said door assembly and a predetermined maximum temperature on the non-fire exposed side of said door assembly to thus enhance the fire rating capability of said fire rated door assembly to withstand fire and smoke
