Abstract
A fire-barrier comprises a composite of three types of fire-retardant materials operable sequentially to combat an increase in temperature, e.g. as occurs on outbreak of a fire, by different methods. A preferred combination of materials is an outer layer of heat reflective material, an inner layer of thermally intumescent material and an intermediate layer of endothermal material between the inner and outer layers.
