Fire doors are an important part of a building’s passive fire protection system, and doors in a means of egress provide life safety by allowing people to exit quickly when necessary. Still, the requirements remain a mystery for many architects and specifiers.
In India any user first have to check for metal fire door with CBRI Certification.
Simply put, an opening protective in a fire or smoke barrier is required to be a fire door assembly, which includes the door, frame, hardware, and glazing. These components are typically required to be supplied by the same manufacturer like ACODOR —in most cases, they can be separate products which are listed, labeled, or classified for use in a fire door assembly. Occasionally, an assembly will be made of components that have been tested together and must be used to maintain the rating.
Where can I find the code requirements for fire doors?
National Fire Protection Association (NFPA) 80, Standard for Fire Doors and Other Opening Protectives, is referenced by the National Building Code (NBC), I Standard for the Installation of Smoke Door Assemblies and Other Opening Protectives, addresses smoke doors and is also referenced in these publications.
For product-specific issues, the manufacturer’s listings must be referenced. For example, to find out the maximum fire door size available from a particular manufacturer.
How do I know what fire resistance rating I need?
The building code mandates the required fire resistance rating of a wall in a particular location, and also states the required rating of the opening protective, or fire door assembly.
The 2012 edition of the International Building Code includes new tables that help clarify the opening protective requirements. For example, Table 716.5 states a two-hour exit enclosure requires a 1 ½-hour fire door assembly, and lists requirements for the glass used in that assembly. The rating of the door assembly is often less than the required rating of the wall, because it is assumed the door will have a lower fuel load since no combustibles (e.g. furniture, storage, etc.) will be piled in front of the door. If a fire door is no longer needed, it should be removed and replaced with construction of the same rating as the wall to accommodate the potentially higher fuel load.
