1. A fireproofing system for protecting an elongate member, comprising: at least one inner layer at least partially wrapped around itself to form an inner passage, the at least one inner layer being configured to generally resist heat;an outer member defining an interior opening, wherein the at least one inner layer is configured to be positioned within the interior opening of the outer member;wherein an elongate member is configured to pass through the inner passage;wherein the at least one inner layer comprises at least one of a ceramic material and another material configured to be relatively heat resistant;wherein the outer member on its own is configured to resist heat exceeding 2000 degrees F., wherein the outer member is configured to protect the at least one inner layer against heat and fire; andat least one layer of felt, wherein the layer of felt is positioned along an interior of the at least one inner layer;wherein a R-value of the at least one inner layer is greater than 50; andwherein the fireproofing system is sized and configured to provide a clearance between the fireproofing system and the elongate member once installed, thereby permitting the elongate member to move relative to the at least one inner layer. 2. The system of claim 1, wherein the another material comprises a silica or silicon-based material. 3. The system of claim 1, wherein the at least one inner layer comprises a glass-fiber material. 4. The system of claim 1, wherein the at least one inner layer overlaps around itself by at least 20 percent of its outer circumference. 5. The system of claim 1, wherein the at least one inner layer overlaps around itself by at least one-eighth of a circumference of the at least one inner layer. 6. The system of claim 1, wherein the at least one inner layer comprises at least one of a ceramic wool, a ceramic foam and a ceramic fabric. 7. The system of claim 1, wherein the at least one inner layer is provided in sheets. 8. The system of claim 1, wherein the at least one inner layer is at least partially secured to an interior wall of the outer member. 9. The system of claim 1, wherein the outer member comprises a silica or silicon material. 10. The system of claim 1, wherein the outer member comprises a thermoplastic. 11. The system of claim 10, wherein the outer member comprises high density, polyethylene. 12. The system of claim 1, wherein the elongate member comprises a structural cable. 13. The system of claim 1, wherein the at least one layer of felt comprises recycled carbon felt. 14. The system of claim 1, wherein the at least one layer of felt is positioned along an interior of the at least one inner layer. 15. The system of claim 1, further comprising at least one interior shell or member along an interior of the at least one inner member. 16. The system of claim 15, wherein the at least one interior shell or member comprises at least one of a ceramic material and another material configured to resist heat. 17. The system of claim 1, further comprising at least one metallic inner member along the innermost portion of the system, the at least one metallic inner member being configured to provide, at a minimum, abrasion resistance to the system. 18. A fireproofing system for protecting an elongate member of a structure, comprising: at least one inner layer defining an inner passage, the at least one inner layer configured to at least partially cover the elongate member, the at least one inner layer configured to generally resist heat; andan outer member defining an interior region, wherein the first layer is configured to be positioned within the interior region of the outer member, wherein the outer member by itself is configured to resist heat exceeding 2000 degrees F., and wherein the outer member is configured to protect the at least one inner layer against heat and fire;wherein system is configured to protect the elongate member or a surface; andwherein the fireproofing system is sized and configured to provide a clearance between the fireproofing system and the elongate member once installed, thereby permitting the elongate member to pass through the inner passage and move relative to the at least one inner layer. 19. A method of fireproofing an elongate member, the method comprising: providing at least one inner layer along or around an elongate member, the at least one inner layer configured to generally resist heat, wherein a clearance is provided between the elongate member and the at least one layer once installed, thereby permitting the elongate member to pass through an inner passage defined by the at least one layer and move relative to the at least one inner layer, wherein the elongate member is configured to be slidably positioned within an interior passage defined by the at least one inner layer; andproviding an outer member around an outside of the at least one inner layer;wherein system is configured to protect the elongate member against heat and/or fire;wherein the outer member is configured to protect the at least one inner layer against heat and fire; andwherein the outer member alone is configured to resist heat exceeding 2000 degrees F. 20. The method of claim 19, further comprising: providing an inner shell or member along an interior of the at least one inner layer;providing at least one metallic member along the exterior of the outer shell or member; andproviding at least one metallic member along the interior of the inner shell or member.
