A flexible fire barrier (10) comprises insulating layers (16a, 18a) and metallic layers (16b, 16c, 18b, 18c). The barrier also comprises two outer layers (12, 14) formed from heat-resistant woven glass fibre cloth. The layers are secured in overlying relationship by mechanical fastening means. The barrier has a joint formed between edge portions of two adjacent lengths of the barrier. At the joint, the insulating layers and the metallic layers of the adjacent lengths overlap one another and the outer layers (12, 14) of the adjacent lengths are joined together to hold the insulating and metallic layers in their overlapping condition. |
