Fire Retardant doors
A Fire Retardant doors is a type of door or movable barrier used as part of a passive fire protection system within buildings to prevent the spread of fire or smoke between separate sections. It is usually the only means of allowing people to pass through a fire-resistant wall.
Apart from the door leaf (the swinging panel of the door) there is the door frame which also has to meet fire rated regulations, intumescent strips, smoke seals, door hardware and the structure that holds the fire door assembly in place. Together, these components form an assembly, typically called a "doorset" which holds a rating, in hours, specifying the amount of time it is able to resist a fire at a given temperature.
Fire Doors are basically to contain a fire to a limited area and to prevent it from spreading to other areas. Fire Doors are available in Wood and Steel and also in Single Leaf, Double Leaf, Sliding (Automatic & Non-Automatic). They are generally made conforming to BS-476 Part 22 and to IS-3614 Part 2.
Depending on the duration to withhold the fire, Fire Doors are rated to 60/90/120/180/240 minutes.
