Description
A fire door tends to be an internal wooden one whose purpose is to enable an emergency escape route through a property and help to compartmentalise a fire, preventing the spread of smoke and flames. These doors do not have to be a fire rated fire door and are usually identified by a sign with a blue circle and white text. Alternatively, a fire protection door must have a proven fire rating that is at least as high as the rest of the building’s structure. This fire rating includes the entire door assembly comprising the door frame, any glazing, intumescent fire and smoke seals and all the door furniture, such as hinges, door closers, latches and locks. Here in the United Kingdom a fire resisting door set should be subjected to either a British Standard Fire Test BS 476 Part 22 1987, or a BS/EN 1634-1 2000 test.
