Code of practice for fire door assemblies Ingestion-build-223009 made from unalloyed and alloyedFire doors are required to provide two main functions: a) To maintain any compartmentation of buildings, which has been introduced to limit the size and spread of fire in order to control the perceived risk b) To allow access to protected escape routes, both vertically and horizontally, without any loss of fire resistance, and limit smoke movement in the structure forming these routes, i. e. protected corridors and protected shafts.
