A structural insulated panel for use in a mine safe room comprising a carbon foam material with a liquid permeability of no greater than about 3.0 darcys, a density of from about 0.03 g/cc to about 0.6 g/cc and a bimodal pore distribution with at least about 90% of the pore volume about 10 to about 150 microns in diameter and at least about 1% of the pore volume about 0.8 to about 3.5 microns.
A mine safe room comprising a structural insulated panel which comprises a carbon foam material with a compressive strength of greater than about 2000 psi, a liquid permeability of no greater than about 3.0 darcys and a bimodal pore distribution with at least about 90% of the pore volume about 10 to about 150 microns in diameter and at least about 1% of the pore volume about 0.8 to about 3.5 microns.
