Edge-protecting device for a door leaf
A door edge-protecting device 1 comprising an elongate body 3 with a channel having two sides 9A 9B suitable for gripping the front and rear faces of the door panel 103 and an intumescent layer 15 covering the whole of the base of the channel. The channel is preferably U shaped and the two side arms 9A 9B are preferably resiliently deflectable and form a channel where the opening is narrower than the base. A method of manufacture is also defined. A spacer 17 may be located between the intumescent layer and the edge of the door and manufactured from a mixture of plastics material and intumescent material. A smoke seal 19 may be provided on the external face of the channel. In use the edge protecting device is fitted over the edge of the door, when exposed to heat in a fire the intumescent material expands pushing the base of the channel outwards and into contact with the door frame thus creating a continuous seal between the base and the frame.
