Abstract: An integrated multi-layer metal insulation structure thermally isolates an interior system from external environments more than 1200° C. Three or more refractory metal sheet layers are separated from one another by respective standoffs, where refractory metal comprises any elemental or alloy metal with a melting point more than 1600° C. Each standoff is in the form of a skeletal cage framework of refractory metal ribs with cells between the ribs. Successive interlayers are offset from one another to shunt the heat transfer laterally at each sheet layer. The ribs may have cutouts and the cells may be partially open. Each crate standoff limits thermal transfer from one sheet layer to the next to less than 2.5 W/mK, including the cells restricting air flow to substantially eliminate convective heat transfer and the skeletal cage framework creating a tortuous thermal path that lowers conductive heat transfer to less than 5% of environmental exposure.
