Abstract
A smoke or fire barrier (1), comprising a head box (2) which contains a roller (9). Extending from the head box are a pair of side guides (3) which guide a metallic foil curtain (5) from the roller, where it is stored, to the ground when deployed. At the bottom of the curtain (5), where it meets the ground when deployed is a bottom bar (4). The metallic foil curtain (5) is made up of individual foil panels (6). The curtain is made from a panel of stainless steel with dimples (8) across it. The dimples allow improved characteristics when rolling and being stored as it holds its shape better. The dimples also provide improved heat transfer characteristics.
