ABSTRACT OF THE DISCLOSURE The invention relates to a fire barrier device which comprises a grid of a structural cellular material. The material has cells which extend through the thickness direction of the grid from face to face thereof and have their walls defined by strip material. The walls are coated with an intumescent material. A surrounding metal frame is provided for the mounting of the grid, the frame defining an inwardly directed channel extending around the periphery of the grid and overlapping the peripheral regions of the faces of the grid. The peripheral regions nest in the channel but are free from attachment thereto so that the peripher- al regions are free to move relative to the frame under fire conditions. An intumescent material lines the frame.
