A fire protection curtain having a curtain panel that includes an outer wall and a chimney defining an inlet disposed on a first side of the chimney and an outlet on another side of the chimney. The chimney is in heat conductive association with the outer wall such that heat from a source outside the outer wall is transmitted to the chimney. Such heat transmission can cause the chimney to draw air into the inlet and expel the air out the outlet by chimney effect. The curtain is flexible and sufficiently large for covering at least a portion of a structure to protect the structure from an external fire.

1. A fire protection curtain, comprising: a curtain panel that includes: an outer wall, anda chimney defining an inlet disposed on a first side of the chimney and an outlet on another side of the chimney, such that heat from a source outside the outer wall is transmitted to the chimney, which heat causes the chimney to draw air into the inlet and expel the air out the outlet by chimney effect;wherein: the fire protection curtain is flexible and sufficiently large for covering at least a portion of a structure to protect the structure from an external fire, andthe panel comprises an inner wall overlapping and spaced from the outer wall to define the chimney therebetween. 2. The fire protection curtain of claim 1, further comprising a spacing element disposed within the chimney and between the inner and outer walls to maintain a spacing therebetween and define air-channels extending therethrough for maintaining the chimney open between the inlet and outlet and maximize airflow through the chimney. 3. The fire protection curtain of claim 2, wherein; the inner and outer walls are flexible, andthe spacing element comprises a porous material having a high porosity configured to reduce restrictions to airflow, the spacing element being resiliently compressible to enable rolling of the panel and expansion of the spacing between the walls upon unfurling of the panel. 4. The fire protection curtain of claim 1, wherein the inner and outer walls are made of sheets of metal foil. 5. The fire protection curtain of claim 1, wherein the panel comprises a plurality of panels, the fire protection curtain further comprising a common vertical support from which more than one of the panels disposed vertically with respect to each other is independently supported. 6. The fire protection curtain of claim 5, wherein the vertical support comprises a cable or wire independently connected to a plurality of the panels. 7. The fire protection curtain of claim 1, wherein the inner wall comprises a thermally insulative material. 8. The fire protection curtain of claim 1, wherein the chimney is in heat conductive association with the outer wall. 9. The fire protection curtain of claim 1, wherein the inlet is on an interior of the panel, and the outlet on an exterior of the panel. 10. The fire protection curtain of claim 9, wherein: the panel comprises a plurality of panels; anda one-way divider is provided at the top and bottom of each of the plurality of the panels of the curtain to define the inlets and outlets thereof, each one-way divider extending from the inner wall of a lower panel to an outer wall of a higher panel to define the outlet from the lower panel and the inlet of the higher panel. 11. The fire protection curtain of claim 1, wherein the structure is a fixed structure. 12. The fire protection curtain of claim 1, wherein the structure is a vehicle. 13. A method of deploying a fire protection curtain to protect a structure, comprising: placing a support element around a peak of a roof of the structure;hoisting the fire protection curtain up to the support element; andunfurling the hoisted fire protection curtain over the structure; wherein the fire protection curtain comprises a plurality of curtains panels, each curtain panel comprising: an outer wall; andan inner wall held spaced from the outer wall to define a chimney between the outer wall and the inner wall to draw air into and expel the air out of the chimney by chimney effect. 14. A method of deploying a fire protection curtain to protect a structure, comprising: placing the fire protection curtain at an elevated position on the structure; andunfurling the fire protection curtain vertically to cover at least a side of the structure; wherein the fire protection curtain comprises: an outer wall; andan inner wall held spaced from the outer wall to define a chimney between the outer wall and the inner wall to draw air into and expel the air out of the chimney by chimney effect. 15. The method of claim 14, wherein the unfurling comprises unrolling or unfolding the fire protection curtain. 16. The method of claim 14, wherein the structure is a vehicle. 17. The method of claim 14, wherein the structure is a fixed structure.
