A fire damper including a frame and a plurality of blades rotatably mounted to the frame such that each blade is rotatable about a respective rotational axis between an open rotational position and a closed rotational position, each blade including at least one substantially planar portion; and a side edge portion which is curved away from a plane of the substantially planar portion, wherein a first curved side edge portion of a first of the blades is adapted to engage a second curved side edge portion of a second of the blades, adjacent the first, when the blades are in the closed position; and wherein the first curved side edge portion curves in an opposite direction to the second curved side edge portion when the first and second blades are engaged.
