Abstract

The fire barrier consists of a frame with a set of blades located across the flow of air through the duct, and coated with a material which swells up under the action of heat, the spacing of the blades being such that the duct is completely blocked by the material afer the heating action has taken place. The blades may be of flat section (2) or of zig-zag shape, the material (3) swelling outwards in all directions. In another design, the blades may be of serpentine shape (5) with holes (6) through the vertical and horizontal faces so that when the coating material (3) swells, the holes are blocked. The slats may be part of an adjustable ventilation grid.
