Liquid sodium silicate fills between two window panes.Wire mesh glass - usually Georgian wired.Fire-resistive windows must remain intact under fire conditions and hose stream impact resistance, and can include: Some fire doors are equipped with integral windows which also have a rating, or have been incorporated at the time of the door test and be subject to the overall door's product certification. Seals may vary in chemical composition, expansion rate, expansion volume, and/or charring characteristics. When intumescent seals are used in the door design, use of the correct seal is crucial in the fire rating performance the door assembly. Gaskets to prevent the passage of smoke.An intumescent strip, which expands when exposed to heat.All of the components of the fire door assembly must bear a listing agencies label (with the exception of ball-bearing hinges which meet the basic build requirements of ANSI 156.2 and NFPA 80) to ensure the components have been tested to meet the fire rating requirements.Įdges of a fire door usually need to have fire rated seals which can be composed of: Together, these components form an assembly, typically called a "doorset" which holds a numerical rating, quantified in minutes or hours of resistance to a test fire. The door frame includes the fire or smoke seals, door hardware, and the structure that holds the fire door assembly in place. Glass sections (including vision panels)īoth the door leaf (the swinging panel of the door) and the door frame are required to meet the guidelines of the testing agency which provides the product listing.Components įire doors may be made of a combination of materials, such as: In the UK the British Woodworking Federation outline the difference between a 'Fire Doorset' and a 'Fire Door Assembly'. All fire doors must be installed with the appropriate fire resistant fittings, such as the frame and door hardware, for it to fully comply with any fire regulations. In the UK, it is Part B of the Building Regulations that sets out the minimum requirements for the fire protection that must be implemented in all dwellings this includes the use of fire doors. Starting September 2016, a common CE marking procedure was available abolishing trade barriers within the European Union for these types of products. In Europe national standards for fire doors have been harmonised with the introduction of the new standard EN 16034, which refers to fire doors as fire-resisting door sets. In North American building codes, it, along with fire dampers, is often referred to as a closure, which can be derated compared against the fire separation that contains it, provided that this barrier is not a firewall or an occupancy separation.
