<p>A fire barrier, in particular a fire barrier suitable for use with railway carriages. The barrier having a first layer being a synthetic fibre insulating material which may be a non-woven felt type material and may be a polyamide, an aromatic polyamide or may be a polysilicic acid. The barrier has a second layer being an intumescent material and may be a coating applied to at least part of one side of the first layer, an epoxy, sodium silicate, potassium silicate and a rheological modifier may be present which could be graphite, amorphous carbon or carbon black. The fire barrier provided herein is intended to be placed within, under, or on top of the floor of a train carriage so that in the event of a fire, for example, due to spillages or derailment, the carriage is insulated from fire for as long as possible. The barrier is lightweight and therefore can be retro-fitted or used to replace fire barriers in existing train carriages to maximise weight savings.</p> |
