<p>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 positioning around a building to protect the building from an external fire.</p> |
