INTUMESCENT MATERIALS ABSTRACT The invention provides an improved casing material for locating, at door edges a brush-like material for preventing the passage of cold smoke, and an intumescent material which expands to obstruct. A tubular body has a slot for the bristles which project outwardly from a brush-like base located in- side the casing, and an internal housing for the brush base insolates the slot from an interior portion of the body. A second slot is provided opposite the first slot. The construction of the body is such that the slots can be opened locally so that the brush base can be fitted through the first slot and the intumescent material may be passed, in strip form, through the second slot.
